This Quarterly Report on Form 10-Q contains forward-looking statements concerning our business, operations and financial performance and condition, as well as our plans, objectives and expectations for our business, operations and financial performance and condition. Any statements contained herein that are not statements of historical facts may be deemed to be forward-looking statements. These statements involve known and unknown risks, uncertainties and other important factors that are in some cases beyond our control and may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

In some cases, you can identify forward-looking statements by terminology such as “aim,” “anticipate,” “assume,” “believe,” “contemplate,” “continue,” “could,” “due,” “estimate,” “expect,” “goal,” “intend,” “may,” “objective,” “plan,” “predict,” “potential,” “positioned,” “seek,” “should,” “target,” “will,” “would,” and other similar expressions that are predictions of or indicate future events and future trends, or the negative of these terms or other comparable terminology.

We have based these forward-looking statements largely on our current expectations and projections about our business, the industry in which we operate and financial trends that we believe may affect our business, financial condition, results of operations and prospects, and these forward-looking statements are not guarantees of future performance or development. These forward-looking statements speak only as of the date of this Quarterly Report on Form 10-Q and are subject to a number of risks, uncertainties and assumptions described in the section titled “Risk Factors” and elsewhere in this Quarterly Report on Form 10-Q. Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, you should not rely on these forward-looking statements as predictions of future events. The events and circumstances reflected in our forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements. We undertake no obligation to publicly update or revise any forward-looking statements contained herein for any reason after the date of this report to conform these statements to new information, actual results or changes in our expectations, except as required by applicable law.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this report, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information.

Revolution Medicines, Inc. (the Company) is a clinical-stage precision oncology company focused on developing ~~novel~~ targeted therapies to inhibit frontier targets ~~primarily within the RAS and mTOR signaling pathways.~~in RAS-addicted cancers. The Company was founded in October 2014 and is headquartered in Redwood City, California.

The Company has incurred net operating losses in each year since inception. As of ~~March 31,~~June 30, 2020, the Company had an accumulated deficit of ~~$176.9~~$204.1 million. Management believes that its existing cash, cash equivalents and marketable securities will enable the Company to fund planned operations for at least 12 months following the issuance date of these condensed consolidated financial statements. The Company has been able to fund its operations through the issuance and sale of common stock and redeemable convertible preferred stock in addition to upfront payments and research and development cost reimbursement received under the Company’s collaboration agreement with Genzyme Corporation, an affiliate of Sanofi. Future capital requirements will depend on many factors, including the timing and extent of spending on research and development and payments the Company may receive under the Sanofi collaboration agreement or future collaboration agreements, if any. There can be no assurance that, in the event the Company requires additional financing, such financing will be available at terms acceptable to the Company if at all. Failure to generate sufficient cash flows from operations, raise additional capital and reduce discretionary spending should additional capital not become available could have a material adverse effect on the Company’s ability to achieve its intended business objectives.

OnIn February ~~18,~~ 2020, the Company closed its initial public offering (IPO), and issued 16,100,000 shares of its common stock (including the exercise in full by the underwriters of their option to purchase an additional 2,100,000 shares of common stock) at a price to the public of $17.00 per share for net proceeds of $250.7 million, after deducting underwriting discounts and commissions of $19.2million and expenses of $3.8million.

In July 2020, the Company issued and sold 6,900,000 shares of its common stock in an underwritten public offering (including the exercise in full by the underwriters of their option to purchase an additional 900,000 shares of the Company’s common stock) at a price of $26.00 per share for net proceeds of $167.9 million, after deducting underwriting discounts and commissions of $10.8 million and offering expenses of $0.7 million.

The condensed consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States (GAAP) and applicable rules of the Securities and Exchange Commission (SEC) regarding interim financial reporting and, in the opinion of management, include all normal and recurring adjustments which are necessary to state fairly the Company's financial position and results of operations for the reported periods. The accompanying condensed consolidated financial statements and related financial information should be read in conjunction with the audited consolidated financial statements and the related notes thereto for the year ended December 31, 2019 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 filed with the SEC on March 30, 2020. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted in accordance with such rules and regulations. The condensed consolidated financial statements for the periods ended ~~March 31,~~June 30, 2020 and ~~March 31,~~June 30, 2019 include the accounts of the Company and its wholly owned subsidiary, Warp Drive Bio, Inc. (Warp Drive). All intercompany balances and transactions have been eliminated in consolidation. The functional and reporting currency of the Company and its subsidiary is the U.S. dollar.

On February 7, 2020, the Company amended and restated its amended and restated certificate of incorporation to effect a 1-for-4.8661 reverse stock split of the Company’s common stock and redeemable convertible preferred stock. The par value and authorized shares of the common stock and redeemable convertible preferred stock were not adjusted as a result of the reverse stock split. All issued and outstanding common stock, options to purchase common stock and per share amounts contained in the financial statements have been retroactively adjusted to give effect to the reverse stock split for all periods presented.

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of

the financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, management evaluates its estimates, including those related to revenue recognition, clinical accruals, valuation of in-process research and development and developed technologies, valuation of the redeemable convertible preferred stock liability, income taxes, useful lives of property and equipment and intangible assets, impairment of goodwill, and stock-based compensation. The extent to which the COVID-19 pandemic may directly or indirectly impact the Company’s business, financial condition and results of operations is highly uncertain and subject to change. The Company considered the potential impact of the COVID-19 pandemic on ~~the~~ its estimates and assumptions and there was not a material impact to the Company’s condensed consolidated financial statements as of and for the three months ended ~~March 31,~~June 30, 2020. Actual results could materially differ from the Company’s estimates, and there may be changes to the estimates in future periods.

Financial instruments that potentially subject the Company to concentration of credit risk consist of cash, cash equivalents and marketable securities. The Company’s cash is held by ~~one~~two financial ~~institution~~institutions in the United States, which management believes to be of high credit quality. The Company invests in money market funds, U.S. government debt securities, U.S. government agency bonds, commercial paper and corporate bonds. The Company has not experienced any losses on its deposits of cash and cash equivalents.

The Company is subject to credit risk as its receivable and collaboration revenue, related party are entirely related to its collaboration agreement with Sanofi. See Note 8, “Sanofi ~~collaboration agreement.~~Collaboration Agreement.”

All of the Company’s clinical trial sites for its RMC-4630 clinical studies are currently located in the U.S. and may be affected by the COVID-19 outbreak due to prioritization of hospital resources toward the COVID-19 outbreak, travel or quarantine restrictions imposed by ~~federal, state or local~~ governments, and the inability to access sites for initiation and patient monitoring and enrollment. As a result, patient screening, new patient enrollment, monitoring and data collection may be affected or delayed. The Company is aware of several clinical sites involved in our RMC-4630 clinical studies that have temporarily stopped or delayed enrolling new patients, with exemptions if ~~appropriate.~~appropriate, and it is possible that other clinical sites may be similarly affected. These developments may delay the Company’s clinical trial timelines. Some of the Company’s third-party manufacturers which it uses for the supply of materials for product candidates or other materials necessary to manufacture product to conduct preclinical tests and clinical trials are located in countries affected by COVID-19, and should they experience disruptions, such as temporary closures or suspension of services, the Company would likely experience delays in advancing clinical trials.

The Company determines if an arrangement is, or contains, a lease at inception and then classifies the lease as operating or financing based on the underlying terms and conditions of the contract. Leases with terms greater than one year are initially recognized on the balance sheet as right-of-use assets and lease liabilities based on the present value of lease payments over the expected lease term. The interest rate implicit in lease contracts is typically not readily determinable. As such, the Company utilizes the incremental borrowing rate, which is the rate incurred to borrow, on a collateralized basis, an amount equal to the lease payments over a similar term and in a similar economic environment of the applicable country or region. Variable lease payments are excluded from the right-of-use assets and operating lease liabilities and are recognized in the period in which the obligation for those payments is incurred.

In February 2016, the ~~FASB~~Financial Accounting Standards Board (FASB) issued ASU No. 2016-02, Leases (ASU 2016-02). ASU 2016-02 provides accounting guidance for both lessee and lessor accounting models. In July 2018, the FASB issued supplemental adoption guidance and clarification to ASC 842 within ASU 2018-10, Codification Improvements to Topic 842, Leases, ASU 2018-11, Leases (Topic 842): Targeted Improvements and ASU 2019-01, Leases (Topic 842): Codification Improvements. ASU 2018-11 provides another transition method in addition to the existing modified retrospective transition method by allowing entities to initially apply the new leasing standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption.

The Company adopted these ASUs on January 1, 2020. For its operating leases with a term greater than twelve months, the Company recognizes a right-of-use asset and a lease liability on its condensed consolidated balance sheets. The Company adopted the new standard using the modified retrospective approach, which resulted in the initial recognition of a lease liability of $11.5 million, and a right‑to‑use asset of $9.1 million, with no adjustment to the accumulated deficit balance. In connection with the lease adoption, the Company also derecognized deferred rent of $2.4 million. The adoption of the new standard did not have an impact on

the condensed consolidated statements of operations. The lease liability is determined as the present value of future lease payments using an estimated rate of interest that the Company would pay to borrow equivalent funds on a collateralized basis at the lease commencement date. In order to estimate the incremental borrowing rate, management estimated its credit rating, adjusted the credit

rating for the nature of the collateral, and benchmarked the borrowing rate against observable yields on comparable securities with a similar term. As of the adoption date, the Company estimated the incremental borrowing rate to be approximately 5%. The Company determined the lease term at the commencement date by considering whether renewal options and termination options are reasonably assured of exercise. The Company elected the practical expedients permitted under ASU 2018-11, which among other things, allowed the Company to carry forward the historical lease classification of those leases in place as of January 1, 2020. The Company elected to exclude from its condensed consolidated balance sheets recognition of leases having a term of 12 months or less (short-term leases). The Company elected to apply the practical expedient and accounted for each lease component and related non-lease component as one single component.

In June 2018, the FASB issued ASU No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting (ASU 2018-07). ASU 2018-07 simplifies the accounting for share-based payments to nonemployees by aligning it with the accounting for share-based payments to employees, with certain exceptions. The Company adopted ASU 2018-07 on January 1, 2020 and concluded that adoption of the standard did not have a material impact on its condensed consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement Disclosure Framework (ASU 2018-13). ASU 2018-13 is part of a broader disclosure framework project by the FASB to improve the effectiveness of disclosures by more clearly communicating the information to the user. ASU 2018-13 is applicable to the Company for the fiscal year beginning after December 15, 2019. The Company adopted the standard on January 1, 2020 and concluded that adoption of the standard did not have a material impact on its condensed consolidated financial statements.

In November 2018, the FASB issued ASU No. 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606 (ASU 2018-18). ASU 2018-18 clarifies that certain transactions between collaborative arrangement participants should be accounted for as revenue under Topic 606 when the counterparty is a customer for a distinct good or service (i.e. a unit of account). For units of account that are in the scope of Topic 606, all of the guidance in Topic 606 should be applied, including the guidance on recognition, measurement, presentation and disclosure. ASU 2018-18 also adds a reference in ASC Topic 808, Collaborative Arrangements (Topic 808) to the unit of account guidance in Topic 606 and requires that it be applied only to assess whether transactions in a collaborative arrangement are in the scope of Topic 606. ASU 2018-18 ~~preclude~~precludes entities from presenting amounts related to transactions with a counterparty in a collaborative arrangement that is not a customer as revenue from contracts with customers. The Company adopted the standard on January 1, 2020 and concluded that adoption of the standard did not have a material impact on its condensed consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13), which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss model. It also eliminates the concept of other-than-temporary impairment and requires credit losses related to available-for-sale debt securities to be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. These changes will result in earlier recognition of credit losses. In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments—Credit Losses (ASU 2018-19) which narrowed the scope and changed the effective date for non-public entities for ASU 2016-13. The FASB subsequently issued supplemental guidance within ASU No. 2019-05, Financial Instruments—Credit Losses (Topic 326): Targeted Transition Relief (ASU 2019-05). ASU 2019-05 provides an option to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost basis. ASU 2016-13 is applicable to the Company for the fiscal year beginning ~~after December 15, 2021.~~on January 1, 2023. Early adoption is permitted. The Company is currently evaluating the impact the adoption of these ASUs will have on its consolidated financial statements and related disclosures.

In August 2018, the FASB issued ASU No. 2018-15, Intangibles—Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (ASU 2018-15). ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use-software. This ASU is effective for the Company for the fiscal year beginning after December 31, 2020, and interim periods within fiscal years beginning after December 31, 2021. The Company is currently evaluating the impact of this ASU on the Company’s consolidated financial statements.

In December 2019, the ~~Financial Accounting Standards Board (FASB)~~FASB issued ASU 2019-12, Income Taxes (Topic 740)-Simplifying the Accounting for Income Taxes (ASU 2019-12). ASU 2019-12 simplifies the accounting for income taxes by removing

certain exceptions to the general principles in Topic 740 and clarifying and amending existing guidance. ASU 2019-12 will be effective for the Company in the first quarter of 2021 with early adoption permitted. The Company is currently assessing the impact of ASU 2019-12 on its consolidated financial statements.

The carrying amounts of the Company’s certain financial instruments, including cash equivalents, accounts payable and accrued expenses and other current liabilities approximate fair value due to their relatively short maturities and market interest rates, if applicable. Refer to Note 4 regarding the fair value of the Company’s available-for-sale securities.

Assets and liabilities recorded at fair value on a recurring basis in the consolidated balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair values. Fair value is defined as the exchange price that would be received for an asset or an exit price that would be paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The authoritative guidance on fair value measurements establishes a three-tier fair value hierarchy for disclosure of fair value measurements as follows:

Level 1—Observable inputs such as unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date;

Level 2—Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the asset or liability. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active; and

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The following table presents information about the Company’s financial assets that are measured at fair value and indicates the fair value hierarchy of the valuation:

The amortized cost and estimated fair value of the Company’s available-for-sale ~~marketable~~ securities by contractual maturity are summarized below as of ~~March 31,~~June 30, 2020:

Depreciation and amortization expense for property and equipment amounted to $0.6 million and $0.5 million for the three months ended ~~March 31,~~June 30, 2020 and 2019, respectively and $1.3 million and $1.1 million for the six months ended June 30, 2020 and 2019, respectively.

Intangible assets, net consist of the following as of ~~March 31,~~June 30, 2020:

Amortization expense for the three months ended ~~March 31,~~June 30, 2020 and 2019 was $0.3 million and $0.3 million, respectively and for the six months ended June 30, 2020 and 2019 was $0.5 million and $0.5 million, respectively.

No impairment has been recognized as of ~~March 31,~~June 30, 2020. Goodwill recorded is not deductible for income tax purposes.

In January 2015, as amended in September 2016, the Company entered into an operating lease for approximately 42,000 square feet of office and laboratory space located inat 700 Saginaw Drive, Redwood City, California, ~~(Redwood City Lease). As of March 31, 2020~~or the ~~Redwood City lease had~~700 Building, with a term through April ~~2023, with~~2023. In April 2020, the Company amended the lease to lease an additional 19,000 square feet of office, laboratory and research and development space located at 300 Saginaw Drive, Redwood City, California, or the 300 Building, beginning on December 15, 2020 and ending December 31, 2030, and to extend the Company’s existing lease term for the 700 Building until December 31, 2030. The Company has the option to extend the lease term for the 700 Building and the 300 Building together for an additional ten years after December 31, 2030. In connection with the lease amendment the Company issued a letter of credit for $0.9 million, which is included in restricted cash on the condensed consolidated balance sheet as of June 30, 2020.

The annual base rent for the lease of the 300 Building is $1.2 million until December 31, 2021, after which the annual base rent will increase by approximately 3.5% in each subsequent year of the lease term. The annual base rent for the lease of the 700 Building remains unchanged through ~~January 2028. The~~April 30, 2023, and increases to $2.8 million for the 12 month period ending April 30, 2024, after which the annual base rent increases by approximately 3.5% in each subsequent year of the lease term.

In conjunction with the lease amendment, the Company assumed a lease in April 2020 for the 300 Building with a lease term expiring on December 14, 2020 for an annual base rent of $0.5 million and subsequently subleased approximately 50% of the 300 Building with an initial term expiring on December 14, 2020.

Through June 30, 2020, the landlord has provided the Company with a$3.4 million in tenant ~~improvements allowance~~improvement allowances for the ~~space leased for~~700 Building, which ~~the Company received $3.4 million, which was~~were recognized as a lease incentive. The lease amendment provides the Company with an additional tenant improvement allowance for a total of $3.3 million to complete the renovation to the 300 building, which the Company has determined to be lessee owned. The lease incentive is being amortized as an offset to rent expense over the lease term in the condensed consolidated statements of operations. ~~In conjunction with~~

Upon the execution of the amendment, which was deemed to be a lease modification, the Company re-evaluated the assumptions used during the adoption of ASC 842 for the lease. The Company determined the amendment consists of two separate contracts under ASC 842. One contract is related to a new right-of-use asset for the 300 Building, which is being accounted for as a new operating lease, and the other is related to the modification of the original lease term for the original 700 Building. As a result, the Company recorded a right-of-use asset of $6.4 million and a lease liability of $9.0 million for the 300 Building and an increase of $14.8 million to the right-of-use asset and lease liability for the 700 Building upon the lease ~~agreement,~~amendment. The Company is recognizing rent expense on a straight-line basis through the ~~Company paid a security deposit~~remaining extended term of ~~$0.3 million which is included in other noncurrent assets on~~ the ~~consolidated balance sheets as of March 31, 2020 and December 31, 2019, respectively.~~respective leases.

As part of the Warp Drive acquisition in October 2018, the Company assumed an operating lease for approximately 22,000 square feet of office and laboratory space located in Cambridge, Massachusetts (Cambridge Lease), which expires in February 2023, with an option to extend the term through February 2028, subject to certain conditions. In March 2019, the Company fully subleased the Cambridge Lease to Casma Therapeutics, Inc. (Casma), a related party, on financial terms substantially the same as the original lease. The sublease term with Casma is through the remainder of the Cambridge Lease term. The sublease by Casma and related sublease payments by Casma to the Company are fully guaranteed by Third Rock Ventures, LLC, a related party. In conjunction with the Cambridge Lease, the Company issued a letter of credit for $0.2 million, which is included in restricted cash on the condensed consolidated balance sheets as of ~~March 31,~~June 30, 2020 and December 31, 2019.

The balance sheet classification of the Company’s lease liabilities ~~were~~was as follows:

For the three months ended ~~March 31,~~June 30, 2020, operating lease cost was ~~$0.4~~$0.7 million, net of sublease income of ~~$0.4~~$0.5 million and tenant improvement allowance credits of $0.1 million. For the six months ended June 30, 2020, operating lease cost was $1.1 million, net of sublease income of $0.9 and tenant improvement allowance credits of $0.1 million. The operating cash flows ~~used~~ for operating leases ~~was $0.8~~were $0.5 million and $1.3 million for the three months and six months ended ~~March 31, 2020. The short-term~~June 30, 2020, respectively. Short-term lease costs were immaterial for the three months and six months ended ~~March 31,~~June 30, 2020.

As of ~~March 31,~~June 30, 2020, the maturities of the Company’s operating lease liabilities were as follows (in thousands):

The amounts representing the tenant improvement allowance, which are recorded in prepaid expenses and other current assets, are expected to be fully received by the Company by the end of the first quarter of 2021.

Operating lease liabilities are based on the net present value of the remaining lease payments over the remaining lease term. In determining the present value of lease payments, the Company uses its incremental borrowing rate. The weighted-average discount rate used to determine the operating lease liability was 5%7.1%. As of ~~March 31,~~June 30, 2020, the weighted-average remaining lease term is ~~3.0~~9.5 years.

As of December 31, 2019, future minimum payments and receipts under the Company’s operating and capital leases and sublease, under the prior lease standard, ASC 840, were as follows:

Rent expense under ASC 840 was $2.0 million for the year ended December 31, 2019, net of sublease income and tenant improvement allowance credits.

From time to time, the Company may bebecome involved in litigation ~~related to claims that arise in the ordinary course of its business activities.~~or other legal proceedings. The Company accrues for these matters when it is probable that losses will be incurred, and these losses can be reasonably estimated. ~~As of March 31, 2020, the~~The Company ~~does~~is not ~~believe~~currently a party to any litigation or legal proceedings that, ~~any such matters, individually or~~ in the ~~aggregate, will~~opinion of the Company’s management, are probable to have a material adverse effect on ~~the Company’s~~our business, financial ~~position,~~condition, results of operations or ~~cash flows.~~prospects.

The Company enters into standard indemnification arrangements in the ordinary course of business. Pursuant to these arrangements, the Company indemnifies, holds harmless and agrees to reimburse the indemnified parties for losses suffered or incurred by the indemnified party, in connection with any trade secret, copyright, patent or other intellectual property infringement claim by any third party with respect to its technology. The term of these indemnification agreements is generally perpetual any time after the execution of the agreement. The maximum potential amount of future payments the Company could be required to make under these arrangements is not determinable. The Company has not incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the Company believes the fair value of these agreements is minimal.

In June 2018, the Company entered into a collaborative research, development and commercialization agreement with Aventis, Inc. (an affiliate of Sanofi), or the Sanofi Agreement, to research and develop SHP2 inhibitors, including RMC-4630, for any indications. The Sanofi Agreement was assigned to Genzyme Corporation, a Sanofi affiliate, in December 2018. Pursuant to the Sanofi Agreement, the Company granted Sanofi a worldwide, exclusive, sublicensable (subject to the Company’s consent in certain circumstances) license under certain of the Company’s patents and know-how to research, develop, manufacture, use, sell, offer for sale, import and otherwise commercialize SHP2 inhibitors, including RMC-4630, for any and all uses, subject to the Company’s exercise of rights and performance obligations under the Sanofi Agreement.

In October 2018, the Company acquired Warp Drive in exchange for issuance of shares of the Company’s Series B redeemable convertible preferred stock and payment of cash. Sanofi was a stockholder of Warp Drive and received the Company’s Series B redeemable convertible preferred stock during the transaction and accordingly became an investor and related party of the Company.

Under the Sanofi Agreement, the Company received a non-refundable, upfront cash payment of $50 million in July 2018 and could also receive up to $520 million in development and regulatory milestone payments, including up to $235 million upon the

achievement of specified development milestones and up to $285 million upon the achievement of certain marketing approval milestones.

The Company has primary responsibility for early clinical development and for the manufacture of SHP2 inhibitors for Phase 1 and non-registrational Phase 2 clinical trials of RMC-4630 pursuant to an initial development plan. A joint research and development committee is responsible for preparing development plans for other SHP2 inhibitors approved by this committee for development, if any. Sanofi ~~also agreed~~is responsible to reimburse the Company ~~for 80% of~~ all internal and external ~~research~~ costs and expenses ~~incurred~~to perform the Company’s activities under the development plans.

The Company is also primarily responsible for performing preclinical research on SHP2 inhibitors, pursuant to an initial research plan ~~for 2019~~from 2018-2020. The research plans beyond 2020 will be determined by the joint research and ~~2020, and for~~development committee, over which Sanofi has final decision-making power subject to certain exceptions. Sanofi is responsible to reimburse the Company all ~~other~~ internal and external costs and expenses incurred to perform activities under the research plans, with the exception of internal and ~~development~~external research costs and expenses under the research plans for 2019 and 2020, for which Sanofi will reimburse the ~~SHP2 program.~~Company 80%. The Company is responsible for 20% of all internal and external research costs incurred under the research ~~plan~~plans for 2019 and 2020.

In the United States, the Company will share equally with Sanofi the profits and losses applicable to commercialization of SHP2 inhibitor products, pursuant to a profit/loss share agreement that the parties will negotiate based on key terms agreed in the Sanofi Agreement. On a product-by-product basis, Sanofi will also be required to pay the Company tiered royalties on annual net sales of each product outside the United States ranging from high single digit to mid-teen percentages.

The Company has primary responsibility for early clinical development of RMC-4630 pursuant to an initial development plan and also has primary responsibility for the manufacture of SHP2 inhibitors for Phase 1 and Phase 2 non-registrational clinical trials, while Sanofi is responsible for manufacturing SHP2 inhibitors for all other clinical trials and commercial supply.

Unless terminated earlier, the Sanofi Agreement will continue in effect until the later of the expiration of all of Sanofi’s milestone and royalty payment obligations and the expiration of the profit/loss share agreement. Sanofi may terminate the Sanofi Agreement in its entirety or on a country-by-country or product-by-product basis for any reason or for significant safety concerns, upon prior notice to the Company. Sanofi may terminate the Sanofi Agreement in its entirety upon a change of control in the Company, with prior notice. Either party may terminate the Sanofi Agreement if an undisputed material breach by the other party is not cured within a defined period of time, or immediately upon notice for insolvency-related events of the other party. The Company may terminate the Sanofi Agreement after a certain number of years if Sanofi develops a competing program without commencing a registrational clinical trial for a SHP2 inhibitor product candidate, and subject to certain other conditions. The Company may also terminate the Sanofi Agreement at any time, if Sanofi ceases certain critical activities for SHP2 inhibitor product candidates for more than a specified period of time, provided that such cessations of critical activity were not a result of certain specified factors, and subject to certain other conditions. Upon any termination of the Sanofi Agreement with respect to any product or country, all licenses to Sanofi with respect to such product or country shall automatically terminate and all rights generally revert back to the Company.

The Company identified the following promises in the agreement (1) the license related to SHP2 inhibitors, (2) the performance of research and development services for Phase 1 clinical studies and Phase 2 clinical trials that are non-registrational clinical trials and (3) the performance of manufacturing services for the non-registrational clinical trials. The Company determined that the license is not distinct from the services within the context of the agreement because the research, development and manufacturing significantly increase the utility of the intellectual property. The intellectual property (IP) related to SHP2 inhibitors, which is proprietary to the Company, is the foundation for the research and development activities. The manufacturing services are a necessary and integral part of the research and development services as they could only be conducted utilizing the outcomes of these services. Given the research and development services under the Sanofi Agreement are expected to involve significant further development of the initial IP, the Company has concluded that the research, development and manufacturing services are not distinct from the license, and thus the license, research and development services and manufacturing services are combined into a single performance obligation.

For revenue recognition purposes, the Company determined that the duration of the contract begins on the effective date of the Sanofi Agreement in July 2018 and ends upon completion of the non-registrational clinical trials. The contract duration is defined as the period in which parties to the contract have present enforceable rights and obligations. The Company analyzed the impact of Sanofi terminating the agreement prior to the completion of these trials and determined that there were significant economic costs to Sanofi for doing so.

The Company determined that the transaction price of the Sanofi Agreement was $196.1 million as of ~~March 31,~~June 30, 2020. In order to determine the transaction price, the Company evaluated all the payments to be received during the duration of the contract. The Company determined that the $50.0 million upfront payment and $146.1 million of estimated variable consideration for expense reimbursements from Sanofi for agreed upon research and development services as of ~~March 31,~~June 30, 2020 constituted consideration to be included in the transaction price, which is to be allocated to the combined performance obligation. Development and regulatory milestones under the Sanofi Agreement were considered but not included in the transaction price, as it is probable that a significant

revenue reversal could occur if they were included. The Company will re-evaluate the transaction price in each reporting period and as uncertain events are resolved or other changes in circumstances occur.

The license, research, development and manufacturing services are combined as one performance obligation that will be performed over the duration of the contract, which is from the effective date of the Sanofi Agreement through to the completion of studies. The Company concluded that it would utilize a cost-based input method to measure proportional performance and to calculate the corresponding amount of revenue to recognize. In applying the cost-based input method of revenue recognition, the Company uses actual costs incurred relative to estimated costs to fulfill the combined performance obligation. These costs consist primarily of internal full-time equivalent efforts and third-party costs. Revenue is recognized based on actual costs incurred as a percentage of total estimated costs as the Company completes its performance obligations. The cumulative effect of revisions to estimated costs to complete the Company’s performance obligations will be recorded in the period in which changes are identified and amounts can be reasonably estimated.

During the three months ended ~~March 31,~~June 30, 2020 and 2019, the Company recognized ~~$11.5~~$10.0 million and ~~$13.2~~$12.3 million of collaboration revenue associated with this agreement, respectively, and $21.6 million and $25.4 million for the six months ended June 30, 2020 and 2019, respectively.

As of ~~March 31,~~June 30, 2020 and December 31, 2019, ~~$16.4~~$14.6 million and $17.1 million of deferred revenue, related party is classified as current and ~~$12.4~~$11.6 million and $14.7 million is classified as noncurrent.

From December 2014 to May 2017, the Company issued a total of 14,430,799 shares of Series A redeemable convertible preferred stock at a price per share of $4.87, for aggregate proceeds of $70.1 million, net of issuance costs.

In March and June 2018, the Company issued a total of 7,731,155 shares of Series B redeemable convertible preferred stock at a price per share of $7.30 for proceeds of $56.2 million, net of issuance costs. In October 2018, the Company issued 6,797,915 shares of Series B redeemable convertible preferred stock in conjunction with acquiring Warp Drive. As part of the Warp Drive acquisition, the Company assumed $2.0 million in convertible notes payable, which was fully converted into 200,493 shares of Series B redeemable convertible preferred stock in October 2018. In November 2018, the Company issued 435,547 shares of Series B redeemable convertible preferred stock at a price per share of $10.03, for proceeds of $4.3 million, net of issuance costs.

In June and July 2019, the Company issued a total 10,004,514 shares of Series C redeemable convertible preferred stock at a price per share of $10.03 for proceeds of $100.0 million, net of issuance costs.

Redeemable convertible preferred stock consists of the following as of December 31, 2019:

Upon the closing of the IPO in February 2020, all shares of redeemable convertible preferred stock then outstanding converted into 39,600,423 shares of common stock. There were no shares of redeemable convertible preferred stock outstanding as of ~~March 31,~~June 30, 2020.

The redeemable convertible preferred stock iswas recorded outside of permanent equity because while it iswas not mandatorily redeemable, it ~~will~~would have become redeemable upon the occurrence of certain liquidation events that are considered not solely within the Company’s control. Accordingly, the redeemable convertible preferred stock has been presented in the mezzanine section on the consolidated balance sheets.

As of ~~March 31,~~June 30, 2020 and December 31, 2019, the Company’s certificate of incorporation authorized the Company to issue 300,000,000 shares and 249,000,000 shares of common stock, respectively, at a par value of $0.0001 per share. Each share of common

stock is entitled to one vote. The holders of common stock are also entitled to receive dividends whenever funds are legally available and when declared by the Board of Directors, subject to prior rights of the redeemable convertible preferred stockholders. As of ~~March 31,~~June 30, 2020, no dividends have been declared to date.

The Company has reserved shares of common stock, on an as-converted basis, for future issuance as follows:

In February 2020, the Company adopted the 2020 Equity Incentive Plan, or the 2020 Plan. The 2020 Plan became effective on February 11, 2020. The 2020 Plan provides for a variety of stock-based compensation awards, including stock options, stock appreciation rights, or SARs, restricted stock awards, restricted stock unit awards, performance bonus awards, performance stock unit awards, dividend equivalents, or other stock or cash based awards. Under the 2020 Plan, the Company generally grants stock-based awards with service-based vesting conditions only. Options and restricted stock unit awards granted typically vest over a four-year period, but may be granted with different vesting terms.

Following the effectiveness of the 2020 Plan, the Company will not make any further grants under the 2014 Equity Incentive Plan, or the 2014 Plan. However, the 2014 Plan will continue to govern the terms and conditions of the outstanding awards granted under it. Shares of common stock subject to awards granted under the 2014 Plan that are forfeited or lapse unexercised and which following the effective date of the 2020 Plan are not issued under the 2014 Plan will be available for issuance under the 2020 Plan.

As of ~~March 31,~~June 30, 2020, there were ~~5,110,075~~4,926,047 shares of common stock reserved for issuance pursuant to the 2020 Plan.

In December 2014, the Company adopted the 2014 Plan which provided for the Company to issue restricted common stock, or to grant incentive stock options or nonqualified stock options for the purchase of common stock, to employees, members of the Board of Directors and consultants of the Company under terms and provisions established by the Board of Directors. The Company generally granted stock-based awards with service-based vesting conditions only. Options granted typically vest over a four-year period but may be granted with different vesting terms.

The following summarizes option activity under both the 2020 Plan and the 2014 Plan:

As of ~~March 31,~~June 30, 2020, there was ~~$22.2~~$23.7 million of unrecognized stock-based compensation expense related to unvested stock options that is expected to be recognized over a weighted-average period of ~~3.0~~2.8 years.

Restricted stock primarily consists of restricted stock unit (“RSU”) awards which have been granted to employees. The value of an RSU award is based on the Company’s stock price on the date of grant. The shares underlying the RSU awards are not issued until the RSUs vest. Upon vesting, each RSU converts into one share of the Company’s common stock.

Activity with respect to the Company’s restricted stock units during the six months ended June 30, 2020 was as follows:

As of June 30, 2020, there was $1.8 million of total unrecognized compensation cost related to restricted stock units that that is expected to be recognized over a weighted average period of 3.3 years.

Stock-based compensation related to options granted to non-employees was $0.2 million and $0.1 million for the three months ended June 30, 2020 and 2019, respectively, and $0.4 million and $0.2 million for the six months ended June 30, 2020 and 2019, respectively.

The Company allows its employees, non-employees and directors to exercise options granted under the 2014 Plan prior to vesting. The shares related to early exercised stock options are subject to the Company’s lapsing repurchase right upon termination of employment at the original purchase price. In order to vest, the holders are required to provide continued service to the Company. The proceeds are initially recorded in other noncurrent liabilities and are reclassified to common stock and additional paid-in capital as the repurchase right lapses. As of June 30, 2020 and December 31, 2019, there were 233,361 and 349,501 shares, respectively, and $0.2 million and $0.3 million, respectively, recorded in other noncurrent liabilities, related to early exercised shares that were subject to repurchase.

In February 2020, the Company adopted the 2020 Employee Stock Purchase Plan, or the 2020 ESPP. Under the 2020 ESPP, employees have the ability to purchase shares of our common stock through payroll deductions at a discount during a series of offering periods of 24 months, each comprised of four six-month purchase periods. The purchase price will be the lower of 85% of the closing trading price per share of the Company’s common stock on the first day of an offering period in which an employee is enrolled or 85% of the closing trading price per share on the purchase date, which will occur on the last trading day of each purchase period.

The Company has reserved for issuance 528,959 shares of common stock pursuant to the 2020 ESPP. As of ~~March 31,~~June 30, 2020, there have been no ~~offering periods have commenced~~purchases under the 2020 ESPP.

~~Stock-based compensation related to options granted to non-employees was $0.2 million and $0.1 million for the three months ended March 31, 2020 and 2019, respectively.~~

The Company allows its employees, non-employees and directors to exercise options granted under the 2014 Plan prior to vesting. The shares related to early exercised stock options are subject to the Company’s lapsing repurchase right upon termination of employment at the original purchase price. In order to vest, the holders are required to provide continued service to the Company. The proceeds are initially recorded in other noncurrent liabilities and are reclassified to common stock and additional paid-in capital as the repurchase right lapses. As of March 31, 2020 and December 31, 2019, there were 292,380 and 349,501 shares, respectively, and $0.3 million and $0.3 million, respectively, recorded in other noncurrent liabilities, related to early exercised shares that were subject to repurchase.

The following table sets forth the computation of basic and diluted net loss per share attributable to common stockholders:

The following outstanding potentially dilutive shares have been excluded from the calculation of diluted net loss per share for the periods presented due to their anti-dilutive effect:

Following the Company’s acquisition of Warp Drive, in January 2019, the Company entered into a sublease agreement with Casma to sublease the Cambridge Lease. The sublease by Casma and related sublease payments by Casma to the Company are fully guaranteed by an affiliate of Third Rock Ventures.

In connection with the Company’s obligations and responsibilities under the Sanofi Agreement, in April 2019, the Company entered into a Clinical Supply Agreement with Genzyme Corporation, or Genzyme, an affiliate of Sanofi, and a Quality Agreement with Sanofi-Aventis Recherche & Developpement, an affiliate of Sanofi. The Quality Agreement was amended in December 2019. Sanofi was a related party at the time both agreements were entered into. The Clinical Supply Agreement governs how the Company will oversee the manufacture and supply of any SHP2 inhibitors requested by Genzyme for use in its clinical development activities under the Sanofi Agreement and provides that Genzyme will compensate the Company for the costs to manufacture any such product plus a 10% fee. The Quality Agreement requires that the production of RMC-4630 meets certain quality standards and puts certain conditions on the Company’s arrangements with subcontractors. The Quality Agreement does not contemplate that any consideration be paid separate from the Sanofi Agreement.

In ~~April~~July 2020, the Company ~~amended~~issued and sold 6,900,000 shares of its ~~Redwood City Lease~~common stock in an underwritten public offering (including the exercise in full by the underwriters of their option to ~~lease~~purchase an additional ~~19,483 square feet~~900,000 shares of office, laboratory and research and development space located at 300 Saginaw Drive, Redwood City, California (the 300 Building) beginning on December 15, 2020 and ending December 31, 2030.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations in conjunction with the condensed consolidated financial statements and the related notes included elsewhere in this Quarterly Report on Form 10-Q. In addition to historical financial information, this discussion contains forward-looking statements based upon current expectations that involve risks and uncertainties. As a result of many factors, including those factors set forth in the “Risk Factors” section of this report, our actual results could differ materially from the results described or implied by the forward-looking statements contained in the following discussion and analysis.

We are a clinical-stage precision oncology company focused on developing ~~novel~~ targeted therapies to inhibit ~~elusive, high-value~~ frontier targets ~~within notorious growth~~in RAS-addicted cancers. We possess sophisticated structure-based drug discovery capabilities built upon deep chemical biology and ~~survival pathways, with particular emphasis on~~cancer pharmacology know-how and innovative, proprietary technologies that enable the ~~RAS and mTOR signaling pathways.~~creation of small molecules tailored to unconventional binding sites. Our understanding of genetic drivers and adaptive resistance mechanisms in cancer, coupled with robust drug discovery and medicinal chemistry capabilities, has guided us to establish a deep pipeline targeting critical signaling nodes within these pathways. This cohesive approach underpins our clinical strategy of exploring mechanism-based dosing paradigms and in-pathway combinations to optimize treatment for cancer patients.

Our most advanced product candidate, RMC-4630, is a potent and selective inhibitor of SHP2, a central node in the RAS signaling pathway. In collaboration with Sanofi, we are evaluating RMC-4630 in a multi-cohort Phase 1/2 clinical program. This RMC-4630 Phase 1/2 program currently consists of ~~two~~four active clinical trials: (1) RMC-4630-01, a Phase 1 study of RMC-4630 as a single ~~agent, and~~agent; (2) RMC-4630-02, a Phase 1b/2 study of RMC-4630 in combination with the MEK inhibitor cobimetinib ~~(Cotellic)~~(Cotellic®); (3) an Amgen-sponsored Phase 1b study of RMC-4630 in combination with Amgen’s KRAS^G12C(OFF) inhibitor, AMG 510 or sotorasib; and (4) a Sanofi-sponsored Phase 1 study of RMC-4630 in combination with the PD-1 inhibitor pembrolizumab (Keytruda®). We previously reported preliminary data from 6387 patients who had enrolled in our RMC-4630-01 Phase 1 study and received RMC-4630 as a monotherapy as of ~~November 6, 2019~~May 4, 2020 and from 8 patients who had enrolled in our RMC-4630-02 Phase 1b/2 combination study and received RMC-4630 in combination with Cotellic® as of November 14, 2019.

Leveraging our proprietary tri-complex technology platform, we are also developing a portfolio of mutant-selective RAS inhibitors that we believe are the first potent, selective, cell-active inhibitors of the active, GTP-bound form of RAS, or RAS(ON). Initially, we will prioritize four mutant RAS(ON) targets—KRAS^G12C, KRAS^G13C, KRAS^G12D and NRAS^G12C—and expect to nominate our first development candidate from this portfolio in 2020. Our pipeline also includes inhibitors of other key nodes within the RAS and mTOR signaling pathways, such as SOS1 and mTORC1. We believe our deep, differentiated pipeline and development strategies provide us with the opportunity to pioneer novel treatment regimens to maximize the depth and durability of clinical benefit and circumvent adaptive resistance mechanisms for patients with cancers dependent on these critical pathways.

~~In addition,~~Additionally, we have ~~two~~ preclinical programs targeting two other key nodes in the RAS and mTOR signaling ~~pathways.~~pathways—SOS1 and mTORC1. Our program targeting SOS1, a protein that plays a key role in converting RAS(OFF) to RAS(ON) in cells, is currently in lead optimization stage. In addition, our preclinical development candidate, RMC-5552, is designed ~~to selectively and deeply inhibit~~for use against tumors featuring mTORC1 ~~thereby preventing phosphorylation and inactivation of 4EBP1, a downstream protein in the mTOR signaling pathway that normally suppresses expression of~~activation, including certain ~~oncogenes such as C-MYC.~~RAS-addicted cancers. We advanced RMC-5552 into IND-enabling development in June ~~2019.~~2019 and are on track to be IND-ready with this compound by the end of 2020.

We have incurred net losses in each year since inception in 2014. Our net losses were ~~$19.5~~$27.2 million and ~~$10.1~~$46.7 million for the three and six months ended ~~March 31,~~June 30, 2020, respectively, as compared to $10.1 million and ~~2019, respectively.~~$20.3 million for the three and six months ended June 30, 2019. As of ~~March 31,~~June 30, 2020, we had an accumulated deficit of ~~$176.9~~$204.1 million. Substantially all of our net losses have resulted from costs incurred in connection with our research and development programs and from general and administrative costs associated with our operations. We expect to continue to incur significant expenses and increasing operating losses over at least the next several years. We expect our expenses will increase in connection with our ongoing activities, as we:

In June 2018, we entered into a collaborative research, development and commercialization agreement with Aventis, Inc. (an affiliate of Sanofi), or the Sanofi Agreement, to research and develop SHP2 inhibitors, including RMC-4630, for any indications. The Sanofi Agreement was assigned to Genzyme Corporation, a Sanofi affiliate, in December 2018. For the purposes of this discussion, we refer to Genzyme Corporation as Sanofi. Pursuant to the Sanofi Agreement, we granted Sanofi a worldwide, exclusive, sublicensable (subject to our consent in certain circumstances) license under certain of our patents and know-how to research, develop, manufacture, use, sell, offer for sale, import and otherwise commercialize SHP2 inhibitors, including RMC-4630, for any and all uses, subject to our exercise of rights and performance of obligations under the Sanofi Agreement. ~~Such~~The intellectual property exclusively licensed to Sanofi includes our interest under any of our solely-owned or jointly-owned inventions arising out of activities undertaken pursuant to the development of SHP2 inhibitor product candidates under the Sanofi Agreement.

Under the Sanofi Agreement, we have primary responsibility for performing preclinical research on SHP2 inhibitors, pursuant to an initial research plan and budget directed toward the identification, validation and optimization of SHP2 inhibitors for 2018-2020. The research plan and budget beyond 2020 will be determined by a joint research and development committee, over which Sanofi has final decision-making power subject to certain exceptions. We have primary responsibility for early clinical development of RMC-4630 pursuant to an initial development plan. ~~The~~A joint research and development committee is responsible for preparing development plans for other SHP2 inhibitors approved by ~~such~~this committee for development, if any. Sanofi is responsible ~~for 80% of~~to reimburse us all ~~internal and external research costs and expenses incurred under the research plan for 2019 and 2020, and for all other~~ internal and external costs and expenses ~~incurred~~ to perform our activities under the ~~research and~~ development plans. We are responsible for 20% of all internal and external research costs incurred under the research plan for 2019 and 2020, in which our share of these costs is estimated to be approximately $2 million in total, representing less than three percent of the anticipated overall budget for the SHP2 program in 2019 and 2020. Sanofi is responsible for all costs under the development plan, and since our SHP2 program is in clinical development, the costs under the development plan are expected to be significantly greater than the costs under the research plan. We are responsible for the manufacture of SHP2 inhibitors for Phase 1 and non-registrational Phase 2 clinical trials at Sanofi’s cost, while Sanofi is responsible for manufacturing SHP2 inhibitors for all other clinical trials and commercial supply. Sanofi has the sole right and responsibility to perform all regulatory activities under the Sanofi Agreement, except with respect to certain trials conducted by us or otherwise conducted under our IND, including our current clinical trials evaluating RMC-4630. Once we have completed all clinical trials for a product candidate that are assigned to us under a development plan, all regulatory approvals for such product candidate are automatically assigned to Sanofi.

We are also primarily responsible for performing preclinical research on SHP2 inhibitors, pursuant to an initial research plan from 2018-2020. The research plans beyond 2020 will be determined by the joint research and development committee, over which Sanofi has final decision-making power subject to certain exceptions. Sanofi is responsible to reimburse us all internal and external costs and expenses incurred to perform activities under the research plans, with the exception of internal and external research costs and expenses under the research plans for 2019 and 2020, for which Sanofi will reimburse us 80%. We are responsible for 20% of all internal and external research costs incurred under the research plans for 2019 and 2020, in which our share of these costs is estimated to be approximately $2 million in total, representing less than three percent of the anticipated overall budget for the SHP2 program in 2019 and 2020.

Unless otherwise delegated to us by the joint commercialization committee, Sanofi also has the sole right and responsibility for all aspects of the commercialization of SHP2 inhibitors in the world for any and all uses, at its expense, subject to our right to elect to co-promote SHP2 inhibitors in the United States. Sanofi is obligated to use commercially reasonable efforts to seek marketing approval for at least one SHP2 inhibitor product candidate in certain major market countries. Sanofi agrees to provide us, and we agree to provide Sanofi, with research, development and commercialization updates through the joint committees.

During the term of the Sanofi Agreement, we may not, alone or with any affiliate or third party, conduct certain research activities with respect to, or develop or commercialize, any product that contains a SHP2 inhibitor outside of the Sanofi Agreement.

Pursuant to the Sanofi Agreement, we received an upfront payment of $50 million from Sanofi in July 2018. Upon the achievement of specified development and regulatory milestones, Sanofi will be obligated to pay us up to $520 million in the aggregate, including up to $235 million upon the achievement of specified development milestones and up to $285 million upon achievement of certain marketing approval milestones. In the United States, we will share equally with Sanofi the profits and losses applicable to commercialization of SHP2 inhibitor products, pursuant to a profit/loss share agreement that the parties will negotiate based on key terms agreed in the Sanofi Agreement. On a product-by-product basis, Sanofi will also be required to pay us tiered royalties on annual net sales of each product outside the United States ranging from high single digit to mid-teen percentages. The royalty payments are subject to reduction under specified conditions set forth in the Sanofi Agreement. Subject to certain exceptions, the royalties are payable on a product-by-product and country-by-country basis until the latest of the expiration of all valid claims covering such product in such country contained in the patents licensed to Sanofi under the Sanofi Agreement and the expiration of regulatory exclusivity for such product in such country.

Sanofi has the sole and exclusive right to file, prosecute and maintain any patents licensed to it pursuant to the Sanofi Agreement, as well as to enforce infringement of or defend claims against such patents that relate to SHP2 inhibitor products.

Unless terminated earlier, the Sanofi Agreement will continue in effect until the later of the expiration of all of Sanofi’s milestone and royalty payment obligations and the expiration of the profit/loss share agreement. Upon expiration of the Sanofi Agreement, the licenses granted to Sanofi thereunder shall become fully paid-up, royalty-free, perpetual and irrevocable. Sanofi may terminate the Sanofi Agreement in its entirety or on a country-by-country or product-by-product basis for any reason or for significant safety concerns, upon prior notice to us within certain specified time periods. Sanofi may terminate the Sanofi Agreement in its entirety upon our change of control, with prior notice. Either party may terminate the Sanofi Agreement if an undisputed material breach by the other party is not cured within a defined period of time, or immediately upon notice for insolvency-related events of the other party. We may terminate the Sanofi Agreement after a certain number of years if Sanofi develops a competing program without commencing a registrational clinical trial for a SHP2 inhibitor product candidate, and subject to certain other conditions. We may also terminate the Sanofi Agreement at any time, if Sanofi ceases certain critical activities for SHP2 inhibitor product candidates for more than a specified period of time, provided that such cessations of critical activity were not a result of certain specified factors, and subject to certain other conditions. Upon any termination of the Sanofi Agreement with respect to any product or country, all licenses to Sanofi with respect to such product or country shall automatically terminate and all rights generally revert back to us. If the Sanofi Agreement is terminated, in its entirety or with respect to a product, other than by us for Sanofi’s material breach or insolvency, we may be required to pay Sanofi royalties on worldwide net sales of reverted products up to mid-single digit percentages based on the development and regulatory status of such reverted products, in each case subject to reductions in accordance with the terms of the Sanofi Agreement.

Through ~~March 31,~~June 30, 2020, we have received an aggregate of ~~$101.4~~$110.0 million from Sanofi, including the upfront payment and research and development expense reimbursements.

In October 2018, we acquired all outstanding shares of Warp Drive Bio, Inc., or Warp Drive. In connection with the acquisition, we issued 6,797,915 shares of our Series B preferred stock and $0.9 million in other consideration, for total consideration valued at $69.0 million. The operating results associated with Warp Drive programs are reflected in our consolidated financial statements beginning on the closing date of the transaction.

In connection with the Warp Drive acquisition, we recorded $55.8 million of in-process research and development, or IPR&D, and $13.6 million of developed technology related to the tri-complex and genome mining platforms. Warp Drive’s RAS programs were accounted for as an IPR&D asset. The IPR&D asset is considered to be an indefinite-lived asset until the completion or abandonment of the associated research and development efforts. Warp Drive’s tri-complex development platform was accounted for as developed technology and is being amortized over seven years.

In addition, we recorded $14.6 million in goodwill associated with the Warp Drive acquisition, which largely relates to the establishment of a deferred tax liability for the non-deductible IPR&D intangible assets acquired. Goodwill will not be amortized. Goodwill and IPR&D will be tested at least annually for impairment. No impairment has been recognized as of ~~March 31,~~June 30, 2020.

Collaboration revenue, related party, consists of revenue under the Sanofi Agreement for our SHP2 program. We entered into the Sanofi Agreement in June 2018 and Sanofi subsequently became a related party in October 2018 as it was a stockholder of Warp Drive to which we issued equity in connection with the acquisition. We received a $50.0 million upfront payment from Sanofi in July 2018, receive reimbursement for research and development services, and are entitled to future potential development and regulatory milestones.

We substantially rely on third parties to conduct our preclinical studies, clinical trials and manufacturing. We estimate research and development expenses based on estimates of services performed, and rely on third party contractors and vendors to provide us with timely and accurate estimates of expenses of services performed to assist us in these estimates. Research and development expenses consist primarily of costs incurred for the development of our product candidates and costs associated with identifying compounds through our discovery platform, which include:

We expense all research and development costs in the periods in which they are incurred. Costs for certain development activities are recognized based on an evaluation of the progress to completion of specific tasks using information and data provided to us by our vendors, collaborators and third-party service providers. Nonrefundable advance payments for goods or services to be received in future periods for use in research and development activities are deferred and recorded as prepaid assets. The prepaid amounts are then expensed as the related goods are delivered or as services are performed.

Under the Sanofi Agreement, all of our RMC-4630 research and development expenses incurred from June 2018 to December 2018 have been reimbursed by Sanofi. All RMC-4630 development expenses and 80% of RMC-4630 research expenses in 2019 and 2020 have been reimbursed, or are reimbursable by Sanofi. These reimbursements from Sanofi are recorded as collaboration revenue. We are responsible for early non-registrational clinical trials and Sanofi is responsible for conducting registrational clinical trials.

We expect our research and development expenses to increase for the foreseeable future as we continue to invest in discovering and developing product candidates and advancing product candidates into later stages of development, which may include conducting larger clinical trials. The process of conducting the necessary research and development and clinical trials to seek regulatory approval for product candidates is costly and time-consuming, and the successful development of our product candidates is highly uncertain. As a result, we are unable to determine the duration and completion costs of our research and development projects or clinical trials or if and to what extent we will generate revenue from the commercialization and sale of any of our product candidates.

General and administrative expenses consist primarily of personnel-related costs, consultants and professional services expenses, including legal, audit, accounting and human resources services, insurance, allocated facilities and information technology costs, and other general operating expenses not otherwise classified as research and development expenses. Personnel-related costs consist of salaries, benefits and stock-based compensation. Facilities costs consist of rent, utilities and maintenance of facilities. We expect our general and administrative expenses to increase for the foreseeable future due to anticipated increases in headcount and as a result of operating as a public company, including expenses related to compliance with the rules and regulations of the Securities and Exchange Commission, the Nasdaq Global Select Market, additional insurance expenses, investor relations activities and other administrative and professional services.

Interest income primarily consists of interest earned on our cash equivalents and marketable securities.

Interest and other expense primarily consists of interest related to our capital lease and interest on other outstanding obligations.

Benefit from income taxes relates to net changes in the deferred tax liability associated with our Warp Drive acquisition resulting from changes in the effective state tax rate and changes in our valuation allowance.

Collaboration revenue, related party consists of revenue under the Sanofi Agreement. Collaboration revenue, related party decreased by ~~$1.6~~$2.3 million, or ~~12%~~18%, during the three months ended ~~March 31,~~June 30, 2020 compared to the same period in 2019. The decrease in collaboration revenue, related party during the three months ended ~~March 31,~~June 30, 2020 was primarily due to lower research and development costs incurred by us for our SHP2 program under the Sanofi Agreement resulting from lower manufacturing costs, which were partially offset by higher clinical trial costs. During the three months ended ~~March 31,~~June 30, 2019, we incurred upfront manufacturing costs related to the supply of RMC-4630 for our clinical trials.

Collaboration revenue, related party decreased by $3.9 million, or 15%, during the six months ended June 30, 2020 compared to the same period in 2019. The decrease in collaboration revenue, related party during the six months ended June 30, 2020 was primarily due to lower research and development costs incurred by us for our SHP2 program under the Sanofi Agreement resulting from lower manufacturing costs, which were partially offset by higher clinical trial costs. During the six months ended June 30, 2019, we incurred upfront manufacturing costs related to the supply of RMC-4630 for our clinical trials.

Research and development expenses increased by ~~$6.3~~$12.8 million, or ~~30%~~64%, during the three months ended ~~March 31,~~June 30, 2020 compared to the same period in 2019. The increase in research and development expenses during the three months ended ~~March 31,~~June 30, 2020 was primarily due to a ~~$5.3~~$12.3 million increase in third party costs for our ~~RAS~~preclinical research portfolio, primarily driven by higher chemistry contract research ~~organizations,~~organization, manufacturing and pharmacology ~~and manufacturing~~ costs; a $1.7 million increase in third party costs for our SOS1 program, which commenced in 2019; a $1.0 million in third party expenses for our 4EBP1 program, which included increased manufacturing and preliminary safety assessment costs; a $0.8$2.1 million increase in salaries and other employee-related expenses due to increased headcount to support our research and development programs; offset by a decrease of ~~$2.0~~$1.4 million in third-party expenses for our SHP2 program resulting from lower manufacturing costs as we incurred upfront manufacturing costs related to the supply of RMC-4630 for our clinical trials during the three months ended ~~March 31,~~June 30, 2019.

Research and development expenses increased by $19.1 million, or 46%, during the six months ended June 30, 2020 compared to the same period in 2019. The increase in research and development expenses during the six months ended June 30, 2020 was primarily due to a $20.3 million increase in third party costs for our preclinical research portfolio, primarily driven by higher chemistry contract research organizations, manufacturing and pharmacology costs; a $3.6 million increase in salaries and other employee-related expenses due to increased headcount to support our research and development programs; offset by a decrease of $3.4 million in third-party expenses for our SHP2 program resulting from lower manufacturing costs as we incurred upfront manufacturing costs related to the supply of RMC-4630 for our clinical trials during the six months ended June 30, 2019.

General and administrative expenses increased by ~~$2.8~~$2.4 million, or ~~114%~~87%, during the three months ended ~~March 31,~~June 30, 2020 compared to the same period in 2019. The increase in general and administrative expenses during the three months ended ~~March 31,~~June 30, 2020 was primarily due to increases of ~~$1.1 million in legal and accounting expenses and $0.4~~$0.8 million in insurance costs as a result of becoming a public company; an increase of $0.6 million in stock-based compensation expense; and an increase of $0.4 million in salaries and other employee-related expenses due to increased ~~headcount;~~headcount.

General and ~~an increase of $0.5 million in stock-based compensation expense.~~

~~Interest income~~administrative expenses increased by ~~$0.6~~$5.1 million, or 100%, during the ~~three~~six months ended ~~March 31,~~June 30, 2020 compared to the same period in 2019. The increase in general and administrative expenses during the six months ended June 30, 2020 was primarily due to increases of $1.2 million in legal and accounting expenses and $1.2 million in insurance costs as a result of becoming a public company; an increase of $1.1 million in stock-based compensation expense; and an increase of $0.8 million in salaries; and other employee-related expenses due to increased headcount.

Interest income increased by $0.3 million and $0.8 million during the three months and six months ended June 30, 2020 compared to the same periods in 2019, respectively. The increases were primarily due to interest income earned from higher average investment balances resulting from the net proceeds from our Series C preferred stock financing in 2019 and IPO in February 2020.

Interest and other expense was less than $0.1 million for the three months and six months ended ~~March 31,~~June 30, 2020 and ~~2019.~~2019, respectively.

Benefit from income taxes was $0.1 million and $0.7 million for the three months and six months ended ~~March 31,~~June 30, 2020 and relates to a reduction in the effective state tax rate and the resulting impact on the deferred tax liabilities from the Warp Drive acquisition. There was no benefit from income taxes for the three months and six months ended ~~March 31,~~June 30, 2019.

On March 27, 2020, the United States enacted the Coronavirus Aid, Relief, and Economic Security (CARES) Act as a result of the Coronavirus pandemic, which contains among other things, numerous income tax provisions. Some of these tax provisions are expected to be effective retroactively for years ending before the date of enactment. The company has evaluated the current legislation and at this time, does not anticipate the CARES Act to have a material impact on its financial statements.

OnIn February ~~18,~~ 2020, we closed our IPO and issued 16,100,000 shares of our common stock at a price to the public of $17.00 per share for net proceeds of approximately $250.7 million, after deducting underwriting discounts and commissions of $19.2 million and expenses of $3.8 million.

In July 2020, we issued and sold 6,900,000 shares of our common stock in an underwritten public offering at a price of $26.00 per share (including the exercise in full by the underwriters of their option to purchase an additional 900,000 shares of our common

stock) for net proceeds of $167.9 million, after deducting underwriting discounts and commissions of $10.8 million and offering expenses of $0.7 million.

Our operations have been financed primarily by our ~~IPO,~~public offerings of common stock, net proceeds of $230.6 million from the issuance of our preferred stock and ~~$101.4~~$110.0 million received under the Sanofi Agreement for upfront payments and for research and development cost reimbursement.

As of ~~March 31,~~June 30, 2020, we had ~~$347.9~~$325.4 million in cash, cash equivalents and marketable securities.

As of ~~March 31,~~June 30, 2020, we had an accumulated deficit of ~~$176.9~~$204.1 million. Our primary use of cash is to fund operating expenses, which consist primarily of research and development expenditures related to our product candidates and our discovery programs, and to a lesser extent, general and administrative expenditures. We expect our expenses to continue to increase in connection with our ongoing activities, in particular as we continue to advance our product candidates and our discovery programs and operate as a public company.

We believe that our existing cash, cash equivalents and marketable securities will enable us to fund our planned operations for at least 12 months following the date of this report.

The timing and amount of our future funding requirements depend on many factors, including:

We expect to need to obtain substantial additional funding in the future for our research and development activities and continuing operations. Sanofi reimburses us for almost all of our research and all of our development expenses associated with our SHP2 program, however Sanofi has the right to terminate the Sanofi Agreement for any reason, upon prior notice to us within certain specified time periods and upon any such termination by Sanofi with respect to any product or country, all licenses to Sanofi with respect to such product or country shall automatically terminate and all rights generally revert back to us. If we need to raise additional capital to fund our operations, funding may not be available to us on acceptable terms, or at all. If we are unable to obtain adequate financing when needed, we may have to delay, reduce the scope of or suspend one or more of our clinical trials, research and development programs or commercialization efforts. We may seek to raise any necessary additional capital through a combination of public or private equity offerings, debt financings and collaborations or licensing arrangements. If we do raise additional capital through public or private equity offerings, the ownership interest of our existing stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect our stockholders’ rights. If we raise additional capital through debt financing, we may be subject to covenants limiting or restricting our ability to take specific actions, such as incurring

additional debt, making capital expenditures or declaring ~~dividends.~~dividends, and if the debt is convertible into our common stock, the

ownership interest of our stockholders may be diluted. If we are unable to raise capital, we may need to delay, reduce or terminate planned activities to reduce costs. Doing so will likely harm our ability to execute our business plans.

The following table summarizes our consolidated cash flows for the periods indicated:

During the ~~three~~six months ended ~~March 31,~~June 30, 2020, cash used in operating activities of ~~$28.0~~$48.0 million was attributable to a net loss of ~~$19.5~~$46.7 million and a net change of ~~$11.5~~$8.1 million in our operating assets and liabilities, partially offset by a net change of ~~$3.0~~$6.8 million in non-cash charges. The non-cash charges primarily consisted of stock-based compensation expense of $3.6 million and depreciation and amortization of ~~$1.4 million and stock-based compensation expense of $1.6~~$1.8 million. The change in operating assets and liabilities was primarily due to a ~~$3.2~~$5.7 million decrease in deferred revenue associated with the Sanofi Agreement and $2.5 million increase in prepaid expenses and other current assets primarily resulting from the timing of prepayments made for research and development ~~activities, a $3.0 million decrease in deferred revenue associated with the Sanofi Agreement, and a $4.0 million decrease in accounts payable and accrued liabilities.~~activities.

During the ~~three~~six months ended ~~March 31,~~June 30, 2019, cash ~~provided by~~used in operating activities of ~~$12.6~~$24.1 million was attributable to a net loss of ~~$10.1~~$20.3 million and a net change of ~~$4.3~~$6.9 million in our operating assets and liabilities, partially offset by a net change of ~~$1.8~~$3.1 million in non-cash charges. The non-cash charges consisted of depreciation and amortization of ~~$0.8~~$1.1 million, stock-based compensation expense of ~~$0.4~~$0.9 million, ~~and~~ a loss on disposal of property and equipment of $0.6 million, and amortization of intangible assets of $0.5 million. The change in operating assets and liabilities was primarily due to a ~~$3.5~~$6.7 million decrease in deferred revenue associated with the Sanofi Agreement and a ~~$0.6~~$1.6 million increase in receivables from a related party resulting from the Sanofi ~~Agreement.~~Agreement, partially offset by a $1.5 million increase in accounts payable.

During the ~~three~~six months ended ~~March 31,~~June 30, 2020, cash ~~provided by~~used in investing activities of ~~$59.7~~$196.2 million, was primarily comprised of purchases of marketable securities of ~~$100.0~~$305.2 million and purchases of property and equipment of ~~$0.6~~$1.0 million, partially offset by cash provided by maturities of marketable securities of ~~$40.9~~$107.1 million and sale of marketable securities of $3.0 million.

During the ~~three~~six months ended ~~March 31,~~June 30, 2019 cash ~~provided by~~used in investing activities of ~~$5.8~~$50.2 million was primarily comprised of purchases of marketable securities of $55.4 million and purchases of property and equipment of $1.0 million, partially offset by proceeds from sale of held-for-sale assets of $6.0 ~~million, partially offset by purchases of property and equipment of $0.3~~ million.

During the ~~three~~six months ended ~~March 31,~~June 30, 2020, cash provided by financing activities of ~~$253.7~~$252.4 million was comprised primarily of proceeds from issuance of common stock, net of offering costs related to our IPO in February 2020.

During the ~~three~~six months ended ~~March 31,~~June 30, 2019, cash provided by financing activities was comprised of proceeds from the issuance of ~~common~~redeemable convertible preferred stock, ~~upon the exercise~~net of ~~stock options.~~issuance costs.

The following table summarizes our commitments and contractual obligations as of ~~March 31,~~June 30, 2020:

Our contractual obligations reflect our minimum payments due for office and laboratory space leases in Redwood City, California and Cambridge, Massachusetts, which are our operating leases, and our equipment leases, which are our capital leases.

Our primary Redwood City lease commenced in January 2015 and asends in December 2030. In April 2020, we amended our Redwood City lease to lease an additional 19,483 square feet of ~~March~~office, laboratory and research and development space located at 300 Saginaw Drive, Redwood City, California beginning on December 15, 2020 and ending December 31, ~~2020, ended in April 2023.~~ 2030. Under the amendment, our existing lease term for the premises located at 700 Saginaw Drive, Redwood City, California was extended until December 31, 2030.

As part of the Warp Drive acquisition, we assumed Warp Drive’s office and laboratory space lease in Cambridge, which ends in February 2023. In March 2019, we fully subleased the Cambridge lease to Casma Therapeutics, Inc., or Casma, on financial terms substantially the same as the original lease. The amounts reflected in the table above include our lease payments for the Cambridge lease, but do not reflect any offset for the sublease payments we are entitled to receive from Casma. The sublease by Casma and related sublease payments by Casma to us are fully guaranteed by Third Rock Ventures, LLC.

In April 2020, we amended our Redwood City Lease to lease an additional 19,483 square feet of office, laboratory and research and development space located at 300 Saginaw Drive, Redwood City, California, or the 300 Building, beginning on December 15, 2020 and ending December 31, 2030. Under the amendment, our existing lease term for the premises located at 700 Saginaw Drive, Redwood City, California, or the 700 Building, was extended until December 31, 2030. The annual base rent for the lease of the 300 Building is approximately $1.2 million until December 31, 2021, after which the annual base rent will increase by approximately 3.5% in each subsequent year of the lease term. The annual base rent for the lease of the 700 Building remains unchanged through April 30, 2023, and annual base rent for the lease of the 700 Building is approximately $2.8 million for the 12 month period ending April 30, 2024, after which the annual base rent increases by approximately 3.5% in each subsequent year of the lease term. These lease payments are not included in the above commitments and contractual obligations table as the lease amendment occurred after March 31, 2020.

We enter into agreements in the normal course of business with contract research organizations for clinical trials, contract manufacturing organizations to provide clinical trial materials and with vendors for preclinical studies and other services and products for operating purposes which are generally cancelable at any time by us upon 30 to 90 days prior written notice. These payments are not included in this table of contractual obligations.

We have not entered into any off-balance sheet arrangements, as defined in Item 303 of Regulation S-K.

We enter into standard indemnification arrangements in the ordinary course of business. Pursuant to these arrangements, we indemnify, hold harmless and agree to reimburse the indemnified parties for losses suffered or incurred by the indemnified party, in connection with any trade secret, copyright, patent or other intellectual property infringement claim by any third party with respect to its technology. The term of these indemnification agreements is generally perpetual any time after the execution of the agreement. The maximum potential amount of future payments we could be required to make under these arrangements is not determinable. We have never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, we believe the fair value of these agreements is minimal.

Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with United States generally accepted accounting principles. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts

of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, as well as the reported expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

For a discussion of our critical accounting estimates, see Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2019 Annual Report on Form 10-K for the year ended December 31, 2019, as filed with the SEC on March 30, 2020, or our 2019 Form 10-K. There have been no material changes to these critical accounting ~~policies and~~ estimates since our 2019 Form 10-K.

In April 2012, the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, was enacted. Section 107 of the JOBS Act provides that an “emerging growth company,” or an EGC, can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933, as amended, or the Securities Act, for complying with new or revised accounting standards. Thus, an EGC can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We are an emerging growth company. We early adopted ASC 606 as the JOBS Act does not preclude an EGC from adopting a new or revised accounting standard earlier than the time that such standard applies to private companies. We have elected to use the extended transition period for any other new or revised accounting standards during the period in which we remain an emerging growth company; however, we may adopt certain new or revised accounting standards early. We will remain an emerging growth company until the earlier of (1) December 31, 2025, (2) the last day of the fiscal year in which we have total annual gross revenue of at least $1.07 billion (3) the last day of the fiscal year in which we are deemed to be a large accelerated filer, which requires the market value of our common stock that is held by non-affiliates to exceed $700.0 million as of the prior June 30th, or (4) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period. Based on our non-affiliated market capitalization as of June 30, 2020, we will cease to be an emerging growth company on December 31, 2021.

We are exposed to market risks in the ordinary course of our business. These risks primarily include interest rate sensitivities. The primary objective of our investment activities is to preserve capital to fund our operations. We also seek to maximize income from our investments without assuming significant risk. To achieve our objectives, we maintain a portfolio of investments in a variety of securities of high credit quality and short-term duration, invested in compliance with our investment policy.

We held cash, cash equivalents and marketable securities of ~~$347.9~~$325.4 million and $122.8 million as of ~~March 31,~~June 30, 2020 and December 31, 2019, respectively, which consisted of bank deposits, money market funds, U.S. government debt securities, U.S. government agency bonds, commercial paper and corporate bonds. Such interest-earning instruments carry a degree of interest rate risk; however, historical fluctuations in interest income have not been significant for us. Due to the short-term maturities of our cash equivalents and marketable securities, an immediate one percent change in interest rates would not have a material effect on the fair value of our cash equivalents and marketable securities.

Our expenses are generally denominated in U.S. dollars. However, we have entered into a limited number of contracts with vendors for research and development services with payments denominated in foreign currencies, including the Euro, British Pound and Chinese Yuan. We are subject to foreign currency transaction gains or losses on our contracts denominated in foreign currencies. To date, foreign currency transaction gains and losses have not been material to our consolidated financial statements, and we have not had a formal hedging program with respect to foreign currency. A 10% increase or decrease in current exchange rates would not have a material effect on our financial results.

Our management, with the participation of our President and Chief Executive Officer and Chairman and our Vice President, Finance and Principal Accounting Officer, our principal executive officer and principal financial officer, respectively, have evaluated our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) prior to the filing of this Quarterly Report on Form 10-Q. Based on that evaluation, our President and Chief Executive Officer and Chairman and our Vice President, Finance and Principal Accounting Officer have concluded that, as of the end of the period covered by this Quarterly Report on Form 10-Q, our disclosure controls and procedures were, in design and operation, effective to the reasonable assurance level.

There were no changes in our internal controls over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the three months ended ~~March 31,~~June 30, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

The effectiveness of any system of internal control over financial reporting, including ours, is subject to inherent limitations, including the exercise of judgment in designing, implementing, operating, and evaluating the controls and procedures, and the inability to eliminate misconduct completely. Accordingly, any system of internal control over financial reporting, including ours, no matter how well designed and operated, can only provide reasonable, not absolute assurances. In addition, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. We intend to continue to monitor and upgrade our internal controls as necessary or appropriate for our business, but ~~cannot assure you~~there can be no assurance that such improvements will be sufficient to provide us with effective internal control over financial reporting.

On February 7, 2020, former employees, Hirdesh Uppal and Catriona Carey, filed lawsuits against us in the Superior Court of the State of California, San Mateo County. Following their termination in March 2019, the plaintiffs alleged wrongful termination in violation of public policy, retaliatory termination in violation of the California labor code and defamation. The plaintiffs were seeking compensatory and punitive damages, general emotional distress damages, prejudgment interest, cost of the lawsuit and attorneys’ fees. We carefully evaluated the plaintiffs’ claims and believed that we had substantial and meritorious defenses to those claims. In March 2020, we settled all claims asserted by Catriona Carey and in May 2020, we settled all claims asserted by Hirdesh Uppal. This matter did not have a material adverse effect on our financial position, results of operations or cash flows.

~~In addition, from~~From time to time, we may become involved in ~~other~~ litigation or other legal proceedings. We are not currently a party to any litigation or legal proceedings that, in the opinion of our management, are probable to have a material adverse effect on our ~~business. Regardless of outcome, litigation can have an adverse impact on our~~ business, financial condition, results of operations ~~and prospects because of defense and settlement costs, diversion of management resources and other factors.~~or prospects.

Our business involves risks, some of which are described below. You should carefully consider these risks, as well as the other information in this Quarterly Report on Form 10-Q, including our financial statements and the related notes and the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” The occurrence of any of the events or developments described below could harm our business, competitive position, financial condition, results of operations, cash flows and ~~growth~~ prospects. In such an event, the market price of our common stock could decline. Many of the following risks and uncertainties are, and will be, exacerbated by the COVID-19 pandemic and any worsening of the global business and economic environment as a result. Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may impair our business operations and the market price of our common stock.

The COVID-19 pandemic, or other epidemic and pandemic diseases or the perception of their effects, could significantly disrupt our business.

Outbreaks of epidemic, pandemic or contagious diseases, such as the recent SARS-CoV-2 virus, or coronavirus, which causes coronavirus disease 2019, or COVID-19, or, historically, the Ebola virus, Middle East Respiratory Syndrome, Severe Acute Respiratory Syndrome or the H1N1 virus, could significantly disrupt our business. These outbreaks pose the risk that we or our employees, contractors, suppliers, and other partners may be prevented from conducting business activities for an indefinite period of time due to spread of the disease within these groups, or due to restrictions that may be requested or mandated by governmental authorities. Business disruptions could include disruptions or restrictions on our ability to travel, as well as temporary closures of all or part of our facilities and the facilities of our partners, clinical trial sites, service providers, suppliers or contract manufacturers. As the COVID-19 pandemic rapidly evolves and spreads, both across the United States and through much of the world, we continue to actively monitor the impact that COVID-19 is having and may have on our business. The pandemic and the measures taken by governmental authorities could disrupt and delay our ongoing clinical trials, our preclinical activities, the manufacture or shipment of both drug substance and finished drug product for our product candidates for preclinical testing and clinical trials and otherwise significantly disrupt our business.

As a result of the COVID-19 pandemic, the state of California, where our corporate offices are located, and many counties where our offices are located or our employees reside, have issued orders for all residents to remain at home, except as needed for essential activities, and have placed restrictions on the scope and conduct of business activities. As a result, we have implemented work from home policies for a majority of our employees that may continue for an indefinite period. We have taken steps to ensure the safety of our patients and employees, while working to ensure the sustainability of our business operations as this unprecedented situation continues to evolve. We continue to evaluate the impact of COVID-19 on the healthcare system and work with healthcare providers supporting our clinical studies to mitigate risk to patients while taking into account regulatory, institutional, and government guidance and policies.

All of our clinical trial sites for our RMC-4630 clinical studies are currently located in the U.S., and may be affected by the COVID-19 outbreak due to prioritization of hospital resources toward the COVID-19 outbreak, travel, quarantine or other restrictions imposed by governments, and the inability to access sites for initiation and patient monitoring and enrollment. As a result, patient screening, new patient enrollment, monitoring and data collection may be affected or delayed. We are aware of several clinical sites involved in our RMC-4630 clinical studies that have temporarily stopped or delayed enrolling new patients, with exemptions if appropriate, and it is possible that other clinical sites may be similarly affected. These developments may delay our clinical trial timelines. Although we are currently not aware of any material impacts on our supply chain of our current or potential product candidates as a result of the COVID-19 pandemic, some of our third-party manufacturers which we use for the supply of materials for product candidates or other materials necessary to manufacture product to conduct preclinical tests and clinical trials are located in countries affected by COVID-19, and should they experience continued disruptions, such as temporary closures or suspension of services, we would likely experience delays in advancing clinical trials. Furthermore, the spread of the virus may affect the operations of key governmental agencies, such as the FDA, which may delay the development of our product candidates. The spread of an infectious disease, including COVID-19, may also result in the inability of our suppliers to deliver components or raw materials on a timely basis or at all. Such events may result in a period of business disruption, and in reduced operations, or doctors and medical providers may be unwilling to participate in our clinical trials.

In addition, a significant outbreak of epidemic, pandemic or contagious diseases in the human population, such as the global COVID-19 pandemic, could result in a widespread health crisis and adversely affect the economies and financial markets of many countries, resulting in an economic downturn that could affect demand for our current or future products.

While the potential economic impact brought by, and the duration of, COVID-19 may be difficult to assess or predict, a continuing widespread pandemic could result in significant disruption of global financial markets, reducing our ability to access capital, which could in the future negatively affect our liquidity. In addition, a recession or market correction resulting from the spread of COVID-19 could materially affect the value of our common stock.

Risks Related to Our Limited Operating History, Financial Position and Need for Additional Capital

We are a clinical-stage precision oncology company with a limited operating history and no products approved for commercial sale. We have incurred significant losses since inception. We expect to incur losses for at least the next several years and may never achieve or maintain profitability, which, together with our limited operating history, makes it difficult to assess our future viability.

Biopharmaceutical product development is a highly speculative undertaking and involves a substantial degree of risk. We are a clinical-stage precision oncology company, and we have only a limited operating history upon which you can evaluate our business and prospects. We currently have no products approved for commercial sale, have not generated any revenue from sales of products and have incurred losses in each year since our inception in October 2014. In addition, we have limited experience as a company and have not yet demonstrated an ability to successfully overcome many of the risks and uncertainties frequently encountered by companies in new and rapidly evolving fields, particularly in the biopharmaceutical industry. Only one of our product candidates, RMC-4630, is currently in clinical development.

Since inception, we have incurred significant net losses. Our net losses were $47.7 million, $41.8 million, and $31.1 million for the years ended December 31, 2019, 2018 and 2017, ~~respectively~~respectively. Our net loss was ~~$19.5~~$27.2 million and $46.7 for the three and six months ended ~~March 31, 2020.~~June 30, 2020, respectively. As of ~~March 31,~~June 30, 2020, we had an accumulated deficit of ~~$176.9~~$204.1 million. We have funded our operations to date primarily with proceeds from the sale of common stock and preferred stock and upfront payments and research and development cost reimbursement received under our collaboration agreement with Genzyme Corporation, an affiliate of Sanofi, or the Sanofi Agreement. To date, we have devoted substantially all of our resources to organizing and staffing our company, business planning, raising capital, acquiring and discovering development programs, securing intellectual property rights and conducting discovery, research and development activities for our programs. We have not yet demonstrated our ability to successfully complete any clinical trials, including pivotal clinical trials, obtain marketing approvals, manufacture a commercial-scale product, or arrange for a third party to do so on our behalf, or conduct sales and marketing activities necessary for successful product commercialization. Our product candidates will require substantial additional development time and resources before we will be able to apply for or receive regulatory approvals and, if approved, begin generating revenue from product sales. We expect to continue to incur significant expenses and operating losses for the foreseeable future.

Our ability to generate revenue from product sales and achieve profitability depends on our ability, alone or with our collaboration partners, to successfully complete the development of, and obtain the regulatory approvals necessary to commercialize, our development programs. We do not anticipate generating revenue from product sales for the next several years, if ever. Our ability to generate future revenue from product sales depends heavily on our, Sanofi’s, and any potential future collaborators’ success in:

Even if one or more of the product candidates that we develop is approved for commercial sale, we anticipate incurring significant costs associated with commercializing any approved product candidate. Our expenses could increase beyond expectations if we are required by the U.S. Food and Drug Administration, or the FDA, the European Medicines Agency, or the EMA, or other regulatory agencies to perform clinical trials or studies in addition to those that we currently anticipate. Even if we are able to generate revenue from the sale of any approved products, we may not become profitable and may need to obtain additional funding to continue operations.

We will require substantial additional financing to achieve our goals, which may not be available on acceptable terms, or at all. A failure to obtain this necessary capital when needed could force us to delay, limit, reduce or terminate our product development or commercialization efforts.

Our operations have consumed substantial amounts of cash since inception. Since our inception, we have invested a significant portion of our efforts and financial resources in research and development activities for our initial preclinical and clinical product candidates. Preclinical studies and clinical trials and additional research and development activities will require substantial funds to complete. As of ~~March 31,~~June 30, 2020, we had cash, cash equivalents and marketable securities of ~~$347.9~~$325.4 million. In February 2020, we raised $250.7 million upon the completion of our initial public offering, or IPO, net of underwriting discounts and commissions and offering expenses. In July 2020, we raised $167.9 million upon the completion of a follow-on public offering, net of underwriting discounts and commissions and offering expenses. We expect to continue to spend substantial amounts to continue the preclinical and clinical development of our current and future programs. If we are able to gain marketing approval for product candidates that we develop, including RMC-4630, we will require significant additional amounts of cash in order to launch and commercialize ~~such~~our product candidates to the extent that ~~such~~their launch and commercialization are not the responsibility of Sanofi or another collaborator that we may contract with in the future. In addition, other unanticipated costs may arise. Because the design and outcome of our current, planned and ~~anticipated~~potential future clinical trials is highly uncertain, we cannot reasonably estimate the actual amounts necessary to successfully complete the development and commercialization of any product candidate we develop.

The timing and amount of our future capital requirements depend on many factors, including:

Other than our Sanofi collaboration on SHP2 inhibitors, including RMC-4630, we do not have any committed external source of funds or other support for our development efforts. We expect to finance our cash needs through a combination of public or private equity offerings, debt financings, credit or loan facilities, collaborations, strategic alliances, licensing arrangements and other marketing or distribution arrangements. In addition, we may seek additional capital due to favorable market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. ~~We believe that our existing cash, cash equivalents and marketable securities enable us to fund our planned operations for at least 12 months following the date of this report.~~

Our ability to raise additional funds will depend on financial, economic and other factors, many of which are beyond our control. Additional funds may not be available when we need them, on terms that are acceptable to us, or at all. If adequate funds are not available to us on a timely basis, we may be required to:

Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights to our technologies.

To date, we have primarily financed our operations through the sale of preferred stock and common stock and upfront payments and research and development cost reimbursement received in connection with our collaboration with Sanofi. We will be required to seek additional funding in the future and ~~currently intend to~~may do so through ~~collaborations,~~a combination of public or private equity offerings, or debt financings, credit or loan facilities, collaborations, strategic alliances, licensing arrangements and other marketing or ~~a combination of one or more of these funding sources.~~distribution arrangements. If we raise additional capital through marketing and distribution arrangements or other collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish certain valuable rights to our product candidates, technologies, future revenue streams or research programs or grant licenses on terms that may not be favorable to us. If we raise additional funds by issuing equity securities, our stockholders may suffer dilution and the terms of any financing may adversely affect the rights of our stockholders. In addition, as a condition to providing additional funds to us, future investors may demand, and may be granted, rights superior to those of existing stockholders. Debt financing, if available, is likely to involve restrictive covenants limiting our flexibility in conducting future business activities, and, in the event of insolvency, debt holders would be repaid before holders of our equity securities would receive any distribution of our corporate assets. Attempting to secure additional financing may also divert our management from our day-to-day activities, which may adversely affect our ability to develop our product candidates.

Our operating results may fluctuate significantly, which will make our future results difficult to predict and could cause our results to fall below expectations.

Our quarterly and annual operating results may fluctuate significantly, which will make it difficult for us to predict our future results. These fluctuations may occur due to a variety of factors, many of which are outside of our control and may be difficult to predict, including:

The cumulative effects of these factors could result in large fluctuations and unpredictability in our quarterly and annual operating results. As a result, comparing our operating results on a period-to-period basis may not be meaningful. Investors should not rely on our past results as an indication of our future performance.

This variability and unpredictability could also result in our failing to meet the expectations of industry or financial analysts or investors for any period. If our revenue or operating results fall below the expectations of analysts or investors or below any forecasts we may provide to the market, or if the forecasts we provide to the market are below the expectations of analysts or investors, the price of our common stock could decline substantially. Such a stock price decline could occur even when we have met any previously publicly stated revenue or ~~earnings~~operating guidance we may provide.

We are early in our development efforts. Our business is dependent on the successful development of our current and future product candidates. If we are unable to advance our current or future product candidates through clinical trials, obtain marketing approval and ultimately commercialize any product candidates we develop, or experience significant delays in doing so, our business will be materially harmed.

We are early in our development efforts, and we have only recently initiated our first clinical trials for our most advanced product candidate, RMC-4630. Our other programs are in the preclinical stage. We have invested substantially all of our efforts and financial resources in the identification of targets and preclinical development of small molecules to treat cancer.

The success of our business, including our ability to finance our company and generate revenue from products in the future, which we do not expect will occur for several years, if ever, will depend heavily on the successful development and eventual commercialization of the product candidates we develop, which may never occur. Our current product candidates, and any future product candidates we develop, will require additional preclinical and clinical development, management of clinical, preclinical and manufacturing activities, marketing approval in the United States and other markets, demonstrating effectiveness to pricing and reimbursement authorities, obtaining sufficient manufacturing supply for both clinical development and commercial production, building of a commercial organization, and substantial investment and significant marketing efforts before we generate any revenues from product sales.

We have not previously submitted a new drug application, or NDA, to the FDA or similar approval filings to a comparable foreign regulatory authority, for any product candidate. An NDA or other relevant regulatory filing must include extensive preclinical and clinical data and supporting information to establish that the product candidate is safe and effective for each desired indication. The NDA or other relevant regulatory filing must also include significant information regarding the chemistry, manufacturing and controls for the product. We cannot be certain that our current or future product candidates will be successful in clinical trials or receive regulatory approval. Further, even if they are successful in clinical trials, our product candidates or any future product candidates may not receive regulatory approval. If we do not receive regulatory approvals for current or future product candidates, we may not be able to continue our operations. Even if we successfully obtain regulatory approval to market a product candidate, our revenue will depend, in part, upon the size of the markets in the territories for which we gain regulatory approval and have commercial rights, as well as the availability of competitive products, whether there is sufficient third-party reimbursement and adoption by physicians.

We plan to seek regulatory approval to commercialize our product candidates both in the United States and in select foreign countries. While the scope of regulatory approval generally is similar in other countries, in order to obtain separate regulatory approval in other countries we must comply with numerous and varying regulatory requirements of such countries regarding safety and efficacy. Other countries also have their own regulations governing, among other things, clinical trials and commercial sales, as well as pricing and distribution of drugs, and we may be required to expend significant resources to obtain regulatory approval and to comply with ongoing regulations in these jurisdictions.

The success of our current and future product candidates will depend on several factors, including the following:

This lengthy approval process as well as the unpredictability of clinical trial results may result in our failing to obtain regulatory approval to market any product candidate we ~~develop, which would significantly harm our business, results of operations and prospects.~~develop. The FDA, the EMA and other comparable foreign authorities have substantial discretion in the approval process, and determining when or whether regulatory approval will be obtained for any product candidate that we develop. Even if we believe the data collected from future clinical trials of our product candidates are promising, ~~such~~this data may not be sufficient to support approval by the FDA, the EMA or any other regulatory authority.

In addition, even if we were to obtain approval, regulatory authorities may approve any of our product candidates for fewer or more limited indications than we request, may not approve the price we ~~intend~~may desire to charge for our products, may grant approval contingent on the performance of costly post-marketing clinical trials, or may approve a product candidate with a label that does not include the labeling claims necessary or desirable for the successful commercialization of that product candidate. Any of the foregoing scenarios could materially harm the commercial prospects for our product candidates.

Further, we have not previously submitted aan NDA to the FDA, or a Marketing Authorization Application, or MAA, to the EMA. We cannot be certain that any of our programs will be successful in clinical trials or receive regulatory approval. Further, product candidates we develop may not receive regulatory approval even if they are successful in clinical trials. If we do not receive regulatory approvals for our product candidates, we may not be able to continue our operations.

Clinical product development involves a lengthy and expensive process, with uncertain outcomes. We may experience delays in completing, or ultimately be unable to complete, the development and commercialization of our current and future product candidates.

To obtain the requisite regulatory approvals to commercialize any of our product candidates, we must demonstrate through extensive preclinical studies and clinical trials that our products are safe or effective in humans. Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during the clinical trial process and our future clinical trial results may not be successful.

We may experience delays in completing our clinical trials or preclinical studies and initiating or completing additional clinical trials. We may also experience numerous unforeseen events during our clinical trials that could delay or prevent our ability to receive marketing approval or commercialize the product candidates we develop, including:

We could encounter delays if a clinical trial is suspended or terminated by us, by the IRBs or ethics committees of the institutions in which such trials are being conducted, by the Data Safety Monitoring Board, or DSMB, for such trial or by the FDA or other regulatory authorities. Such authorities may impose such a suspension or termination due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA or other regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a product, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. Many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of marketing approval of our product candidates.

If we experience delays in the completion of, or termination of, any clinical trial of our product candidates, the commercial prospects of our product candidates will be harmed, and our ability to generate product revenues from any of these product candidates will be delayed. In addition, any delays in completing our clinical trials will increase our costs, slow down our product candidate development and approval process and jeopardize our ability to commence product sales and generate revenues. ~~Significant clinical~~Clinical trial delays could also allow our competitors to bring products to market before we do or shorten any periods during which we have the exclusive right to commercialize our product candidates and impair our ability to commercialize our product ~~candidates and may harm our business and results of operations.~~candidates.

In addition, based on our own preclinical data and supported by observations by others, we are evaluating intermittent dosing schedules in our clinical program to allow us to maximize dose intensity and the depth of response. When dosed in clinical trials, this intermittent dosing approach may reduce patient compliance.

~~Any of these occurrences may harm our business, financial condition and prospects significantly. In addition, many~~Many of the factors described above that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our product candidates or result in the development of our product candidates being stopped early.

Historically, direct inhibition of any RAS protein ~~itself~~ has been challenging due to a lack of tractable, or “druggable,” binding pockets and we are not aware of any programs in clinical development that have successfully targeted any RAS(ON) protein. Given this approach is unproven, it may not be successful.

Historically, direct inhibition of any RAS protein has been challenging due to a lack of tractable, or “druggable,” binding pockets. Our tri-complex technology has enabled us to develop what we believe to be the first potent, selective cell-active inhibitors of multiple mutant RAS(ON) proteins. We are not aware of any programs in clinical development that have successfully targeted any RAS(ON) protein. We cannot be certain that our approach will lead to the development of approvable or marketable products, alone or in combination with other therapies.

The results of preclinical studies and early-stage clinical trials may not be predictive of future results.

The results of preclinical studies may not be predictive of the results of clinical trials, and the results of any early-stage clinical trials we commence may not be predictive of the results of the later-stage clinical trials. Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy despite having progressed through preclinical studies and initial clinical trials. There can be no assurance that any of our current or future clinical trials will ultimately be successful or support further clinical development of any of our product candidates. There is a high failure rate for drugs proceeding through clinical trials. A number of companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in clinical development even after achieving promising results in earlier studies. Even if our clinical trials are completed, the results may not be sufficient to obtain regulatory approval of any products. ~~Any such setbacks in our clinical development could have a material adverse effect on our business and operating results.~~

Interim, “topline” and preliminary data from our clinical trials may differ materially from the final data.

From time to time, we may disclose interim data from our clinical trials. For example, we have reported interim Phase 1 clinical data for RMC-4630 as a single agent and interim Phase 1b/2 clinical data for RMC-4630 in combination with the MEK inhibitor

cobimetinib. In both cases, this interim data included limited number of patients and time of exposure to the study drug. Interim data from clinical trials are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more data on existing patients become available. For example, we have reported interim Phase 1 clinical data for RMC-4630 as a single agent. As of the cutoff date, of November 6, 2019, 63 patients had received treatment: 49 patients on a daily dosing schedule with a median exposure to study drug of only 1.8 months, and 14 patients on an intermittent dosing schedule, with median exposure to study drug of only 1.6 months. We have also reported interim Phase 1b/2 clinical data for RMC-4630 in combination with the MEK inhibitor cobimetinib. As of the cutoff date of November 14, 2019, these data included eight patients with median exposure to study drug of only 1.4 months. Our clinical trial program is ongoing, and the final results may be materially different from what we previously reported. ~~Adverse differences between interim data and final data could significantly harm our business, financial condition, results of operations and prospects.~~

From time to time, we may also publicly disclose preliminary or “topline” data from our clinical trials, which are based on a preliminary analysis of then-available data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the data related to the particular ~~study or~~ trial. We also make assumptions, estimations, calculations and conclusions as part of our analyses of data, and we may not have received or had the opportunity to fully and carefully evaluate all data. As a result, the topline results that we report may differ from future results of the same clinical trials, or different conclusions or considerations may qualify such topline results once additional data have been received and fully evaluated. Topline data also remain

subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, topline data should be viewed with caution until the final data are available.

Further, others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the value of the particular program, the approvability or commercialization of the particular product candidate or product and the value of our company in general. In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is typically a summary of extensive information, and you or others may not agree with what we determine is the material or otherwise appropriate information to include in our disclosure, and any information we determine not to disclose may ultimately be deemed significant with respect to future decisions, conclusions, views, activities or otherwise regarding a particular product, product candidate or our business. If the topline data that we report differ from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, and commercialize, our product candidates may be ~~harmed, which could harm our business, financial condition, operating results and prospects.~~harmed.

If we encounter difficulties enrolling patients in our clinical trials, our clinical development activities could be delayed or otherwise be adversely affected.

The timely completion of clinical trials in accordance with their protocols depends, among other things, on our ability to enroll a sufficient number of patients who remain in the trial until its conclusion. We may experience difficulties in patient enrollment in our clinical trials for a variety of reasons. The enrollment of patients depends on many factors, including:

In addition, our clinical trials will compete with other clinical trials for product candidates that are in the same therapeutic areas (and that seek to evaluate patients with cancer cells having the same mutations, particularly with patients having KRAS^G12C mutations) as our current and potential future product candidates. This competition will reduce the number and types of patients available to us, because some patients who might have opted to enroll in our trials may instead opt to enroll in a trial conducted by one of our competitors. Since the number of qualified clinical investigators is limited, we conduct some of our clinical trials at the same clinical trial sites that some of our competitors use, which will reduce the number of patients who are available for our clinical trials at such sites. Moreover, because our current and potential future product candidates may represent a departure from more commonly used methods for cancer treatment, potential patients and their doctors may be inclined to use conventional therapies, such as chemotherapy, rather than enroll patients in our ongoing or any future clinical trials.

services, we would likely experience delays in advancing these trials. ~~Currently, we expect no material impact on the clinical supply of RMC-4630.~~

Delays in patient enrollment may result in increased costs or may affect the timing or outcome of clinical trials, which could prevent completion of these trials and adversely affect our ability to advance the development of the product candidates we develop.

Our current or future product candidates may cause undesirable side effects or have other properties when used alone or in combination with other approved products or investigational new drugs that could delay or halt their clinical development, prevent their marketing approval, limit their commercial potential or result in significant negative consequences.

Undesirable or clinically unmanageable side effects could occur and cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of marketing approval by the FDA or comparable foreign regulatory authorities. Results of our trials could reveal a high and unacceptable severity and prevalence of side effects or unexpected characteristics.

~~The RMC-4630-01 study is evaluating~~For example, the safety ~~pharmacokinetics and pharmacodynamic effects of RMC-4630 as~~data released for our RMC-4630-01 trial with a single agent under daily and intermittent schedules. For those receiving RMC-4630 on the intermittent dosing schedule, there was one treatment-related serious adverse event, or SAE, (grade 3 abdominal distention) as of the cutoff date of ~~November 6, 2019. No treatment-related grade~~May 4, 2020 included both serious adverse events, or ~~grade 5~~SAEs, and other adverse events, or AEs ~~had been reported as of~~and the ~~cutoff date. The most common treatment-related AEs~~safety data we released for the intermittent dosing group were anemia (35.7%), fatigue (35.7%), thrombocytopenia (35.7%) and edema (28.6%). For those receiving RMC-4630 on the daily schedule, three SAEs were deemed possibly or probably related to the treatment (dehydration, anasarca (generalized edema) and thrombocytopenia), and an additional three SAEs (extensive metastases of tumor in the lungs with grade 4 respiratory failure, fever and radiologic evidence of infectious pneumonia with grade 4 respiratory failure and a single reading of grade 3 prologation of QTc) were reported in which the investigator was unable to rule out an association with the treatment. The most common treatment-related AEs for the daily dosing group were thrombocytopenia (28.6%), diarrhea (24.5%) and anemia (22.4%).

~~The~~our RMC-4630-02 study is evaluating the safety, tolerability and pharmacokinetics of RMC-4630 and cobimetinib using intermittent dosing of RMC-4630 with daily dosing of cobimetinib. Alternative dosing schedules using intermittent dosing of one or both RMC-4630 and cobimetinib are also under evaluation. Adverse events were consistent with the expected mechanistic effects of both SHP2 inhibition and MEK inhibition. No SAEs or grade 4 or 5 AEs were reported in the RMC-4360-02 study as of the cutoff date of November 14, 2019. The most common AEs related to RMC-4630 were diarrhea (25.0%) and edema (25.0%). The most common AE related to cobimetinib was edema (25.0%).included AEs.

Although our current and future product candidates will undergo safety testing to the extent possible and, where applicable, under such conditions discussed with regulatory authorities, not all adverse effects of drugs can be predicted or anticipated. Unforeseen side effects could arise either during clinical development or, if such side effects are more rare, after our products have been approved by regulatory authorities and the approved product has been marketed, resulting in the exposure of additional patients. So far, we have not ~~previously~~ demonstrated that RMC-4630 or any other product candidate is safe in humans, and we cannot predict if ongoing or future clinical trials will do so.

Furthermore, certain of our product candidates, such as RMC-4630, are currently being, and may in the future be, co-administered with approved or experimental therapies, such as Roche’s cobimetinib, Amgen’s ~~AMG 510,~~sotorasib, Merck’s pembrolizumab, a PD-1 inhibitor, or Lilly’s LY-3214996. These combinations may have additional side effects. The uncertainty resulting from the use of our product candidates in combination with other therapies may make it difficult to accurately predict side effects in future clinical trials.

If any of our product candidates receives marketing approval and we or others later identify undesirable side effects caused by such products, a number of potentially significant negative consequences could result, including:

Any of the foregoing events could prevent us from achieving or maintaining market acceptance of the particular product candidate, if ~~approved, and result in the loss of significant revenues to us, which would adversely affect our business, financial condition, results of operations and prospects.~~approved. In addition, if one or more of our product candidates prove to be unsafe, our entire technology platform and pipeline could be ~~affected, which would have a material adverse effect on our business, financial condition, results of operations and prospects.~~affected.

Even if we complete the necessary preclinical studies and clinical trials, the marketing approval process is expensive, time-consuming and uncertain and may prevent us or any of our existing or potential future collaboration partners from obtaining approvals for the commercialization of RMC-4630 and any other product candidate we develop.

Any current or future product candidate we may develop and the activities associated with their development and commercialization, including their design, testing, manufacture, safety, efficacy, recordkeeping, labeling, storage, approval, advertising, promotion, sale, and distribution, are subject to comprehensive regulation by the FDA and other regulatory authorities in the United States and by comparable authorities in other countries. Failure to obtain marketing approval for a product candidate will prevent us from commercializing the product candidate in a given jurisdiction. We have not received approval to market any product candidates from regulatory authorities in any jurisdiction and it is possible that none of our current or future product candidates will ever obtain regulatory approval. We have no experience in filing and supporting the applications necessary to gain marketing approvals and expect to rely on third-party CROs or regulatory consultants to assist us in this process. Securing regulatory approval requires the submission of extensive preclinical and clinical data and supporting information to the various regulatory authorities for each therapeutic indication to establish the product candidate’s safety and efficacy. Securing regulatory approval also requires the submission of information about the product manufacturing process to, and inspection of manufacturing facilities by, the relevant regulatory authority. Any product candidates we develop may not be effective, may be only moderately effective, or may prove to have undesirable or unintended side effects, toxicities or other characteristics that may preclude our obtaining marketing approval or prevent or limit commercial use.

The process of obtaining marketing approvals, both in the United States and abroad, is expensive, may take many years if additional clinical trials are required, if approval is obtained at all, and can vary substantially based upon a variety of factors, including the type, complexity, and novelty of the product candidates involved. Changes in marketing approval policies during the development period, changes in or the enactment of additional statutes or regulations, or changes in regulatory review for each submitted product application, may cause delays in the approval or rejection of an application. The FDA and comparable authorities in other countries have substantial discretion in the approval process and may refuse to accept any application or may decide that our data are insufficient for approval and require additional preclinical, clinical or other studies. In addition, varying interpretations of the data obtained from preclinical and clinical testing could delay, limit, or prevent marketing approval of a product candidate. Any marketing approval we ultimately obtain may be limited or subject to restrictions or post-approval commitments that render the approved product not commercially viable.

If we experience delays in obtaining approval or if we fail to obtain approval of any current or future product candidates we may develop, the commercial prospects for those product candidates may be ~~harmed, and our ability to generate revenues will be materially impaired.~~harmed.

Obtaining and maintaining marketing approval of our current and future product candidates in one jurisdiction does not mean that we will be successful in obtaining marketing approval of our current and future product candidates in other jurisdictions.

Obtaining and maintaining marketing approval of our current and future product candidates in one jurisdiction does not guarantee that we will be able to obtain or maintain marketing approval in any other jurisdiction, while a failure or delay in obtaining marketing approval in one jurisdiction may have a negative effect on the marketing approval process in others. For example, even if the FDA grants marketing approval of a product candidate, comparable regulatory authorities in foreign jurisdictions must also approve the manufacturing, marketing and promotion of the product candidate in those countries. Approval procedures vary among jurisdictions and can involve requirements and administrative review periods different from, and greater than, those in the United States, including additional preclinical studies or clinical trials as clinical studies conducted in one jurisdiction may not be accepted by regulatory authorities in other jurisdictions. In many jurisdictions outside the United States, a product candidate must be approved for reimbursement before it can be approved for sale in that jurisdiction. In some cases, the price that we may intend to charge for our products is also subject to approval.

We may also submit marketing applications in other countries. Regulatory authorities in jurisdictions outside of the United States have requirements for approval of product candidates with which we must comply prior to marketing in those jurisdictions. Obtaining foreign marketing approvals and compliance with foreign regulatory requirements could result in significant delays, difficulties and costs for us and could delay or prevent the introduction of our products in certain countries. If we fail to comply with the regulatory requirements in international markets ~~and/~~or receive applicable marketing approvals, our target market will be reduced and our ability to realize the full market potential of our product candidates will be harmed.

Adverse events in the field of oncology or the biopharmaceutical industry could damage public perception of our current or future product candidates and negatively affect our business.

The commercial success of our products will depend in part on public acceptance of the use of targeted cancer therapies. While a number of targeted cancer therapies have received regulatory approval and are being commercialized, our approach to targeting cancer cells carrying tumor causing mutations, including oncogenic RAS(ON) pathway mutations, is novel and unproven. Adverse events in clinical trials of our product candidates, or post-marketing activities, or in clinical trials of others developing similar products and the resulting publicity, as well as any other adverse events in the field of oncology that may occur in the future, could result in a decrease in demand for any product that we may develop. If public perception is influenced by claims that the use of cancer therapies is unsafe, whether related to our therapies or those of our competitors, our products may not be accepted by the general public or the medical community.

Future adverse events in oncology or the biopharmaceutical industry could also result in greater governmental regulation, stricter labeling requirements and potential regulatory delays in the testing or approvals of our products. Any increased scrutiny could delay or increase the costs of obtaining marketing approval for the product candidates we develop.

Even if we receive marketing approval of a product candidate, we will be subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense and we may be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated problems with our products, if approved.

Any marketing approvals that we receive for any current or future product candidate may be subject to limitations on the approved indicated uses for which the product may be marketed or the conditions of approval, or contain requirements for potentially costly post-market testing and surveillance to monitor the safety and efficacy of the product candidate. The FDA may also require REMS as a condition of approval of any product candidate, which could include requirements for a medication guide, physician communication plans or additional elements to ensure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. In addition, if the FDA or a comparable foreign regulatory authority approves a product candidate, the manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion, import and export and record keeping for the product candidate will be subject to extensive and ongoing regulatory requirements. These requirements include submissions of safety and other post-marketing information and reports, registration, as well as continued compliance with current Good Manufacturing Practice, or cGMP, and Good Clinical Practice, or GCP, for any clinical trials that we conduct post-approval. Later discovery of previously unknown problems with any approved candidate, including adverse events of unanticipated severity or frequency, or with our third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may result in, among other things:

The FDA’s and other regulatory authorities’ policies may change, and additional government regulations may be enacted that could prevent, limit or delay marketing approval of a product. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have ~~obtained, and we may not achieve or sustain profitability.~~obtained.

Even if a current or future product candidate receives marketing approval, it may fail to achieve the degree of market acceptance by physicians, patients, third-party payors and others in the medical community necessary for commercial success.

If any current or future product candidate we develop receives marketing approval, whether as a single agent or in combination with other therapies, it may nonetheless fail to gain sufficient market acceptance by physicians, patients, third-party payors, and others in the medical ~~community.~~community to be viable product. For example, current approved immunotherapies, and other cancer treatments like chemotherapy and radiation therapy, are well established in the medical community, and doctors may continue to rely on these therapies. ~~If the product candidates we develop do not achieve an adequate level of acceptance, we may not generate significant product revenues and we may not become profitable.~~ The degree of market acceptance of any product candidate, if approved for commercial sale, will depend on a number of factors, including:

The market opportunities for any current or future product candidate we develop, if and when approved, may be limited to those patients who are ineligible for established therapies or for whom prior therapies have failed, and may be small.

Cancer therapies are sometimes characterized as first-line, second-line, or third-line, and the FDA often approves new therapies initially only for third-line use. When cancer is detected early enough, first-line therapy, usually chemotherapy, hormone therapy, surgery, radiation therapy or a combination of these, is sometimes adequate to cure the cancer or prolong life without a cure. Second- and third-line therapies are administered to patients when prior therapy is not effective. We expect to initially seek approval of RMC-4630 and any other product candidates we develop as a therapy for patients who have received one or more prior treatments. Subsequently, for those products that prove to be sufficiently beneficial, if any, we would expect to seek approval potentially as a first-line therapy, but there is no guarantee that product candidates we develop, even if approved, would be approved for first-line therapy, and, prior to any such approvals, we may have to conduct additional clinical trials.

The number of patients who have the cancers we are targeting, including those with the necessary mutations, may turn out to be lower than expected. Additionally, the potentially addressable patient population for our current programs or future product candidates may be limited, if and when approved. Even if we obtain significant market share for any product candidate, if and when approved, if the potential target populations are small, we may never achieve ~~profitability~~commercial success without obtaining marketing approval for additional indications, including to be used as first- or second-line therapy.

We are developing RMC-4630 in combination with Roche’s cobimetinib, with Amgen’s sotorasib, and Merck’s pembrolizumab, and may in the future, develop RMC-4630 and other product candidates in combination with one or more currently approved cancer therapies. Even if any product candidate we develop were to receive marketing approval or be commercialized for use in combination with other existing therapies, we would continue to be subject to the risks that the FDA or similar regulatory authorities outside of the United States could revoke approval of the therapy used in combination with our product candidate or that safety, efficacy, manufacturing or supply issues could arise with these existing therapies. Combination therapies are commonly used for the treatment of cancer, and we would be subject to similar risks if we develop any of our product candidates for use in combination with other drugs or for indications other than cancer. This could result in our own products being removed from the market or being less successful commercially.

We may also evaluate RMC-4630 or any other current or future product candidates in combination with one or more other cancer therapies, such as ~~AMG 510 or~~ Lilly’s LY-3214996, that have not yet been approved for marketing by the FDA or similar regulatory authorities outside of the United States or with approved cancer therapies at an unapproved dose and/or schedule, and/or with approved cancer therapies in unapproved indications. We will not be able to market and sell RMC-4630, or any product candidate we

we develop in combination with any such cancer therapies, outside existing approved labels that do not ultimately obtain marketing approval.

If the FDA or similar regulatory authorities outside of the United States do not approve ~~these other~~the drugs we choose to evaluate in combination with or any product candidate we develop or revoke their approval of, or if safety, efficacy, manufacturing, or supply issues arise with, ~~the~~these drugs, ~~we choose to evaluate in combination with or any product candidate we develop,~~ we may be unable to obtain approval of or market or any product candidate we develop.

In addition, Sanofi primarily controls the research and development activities of our SHP2 inhibitors, including RMC-4630, pursuant to the terms of the Sanofi Agreement, and may disagree with us regarding which other therapies should be evaluated in combination with RMC-4630. As a result of any such disagreement, our completion of a trial in combination with our preferred combination product candidate may be delayed or prevented. We rely on Sanofi for the supply of RMC-4630 for future combination studies and if Sanofi is unwilling to supply RMC-4630 to be used in combination with a product candidate from our pipeline, our ability to complete a trial evaluating such combination may be delayed or prevented.

We face significant competition, and if our competitors develop and market products that are more effective, safer or less expensive than the product candidates we develop, our commercial opportunities will be negatively impacted.

The life sciences industry is highly competitive. We are currently developing therapies that will compete, if approved, with other products and therapies that currently exist or are being developed. Products we may develop in the future are also likely to face competition from other products and therapies, some of which we may not currently be aware. We have competitors both in the United States and internationally, including major multinational pharmaceutical companies, established biotechnology companies, specialty pharmaceutical companies, universities and other research institutions. Many of our competitors have significantly greater financial, manufacturing, marketing, product development, technical and human resources than we do. Large pharmaceutical companies, in particular, have extensive experience in clinical testing, obtaining marketing approvals, recruiting patients and manufacturing pharmaceutical products. These companies also have significantly greater research and marketing capabilities than we do and may also have products that have been approved or are in late stages of development, and collaborative arrangements in our target markets with leading companies and research institutions. Established pharmaceutical companies may also invest heavily to accelerate discovery and development of novel compounds or to in-license novel compounds that could make the product candidates that we develop obsolete. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. As a result of all of these factors, our competitors may succeed in obtaining patent protection and/or marketing approval or discovering, developing and commercializing products in our field before we do.

There are a large number of companies developing or marketing treatments for cancer, including many major pharmaceutical and biotechnology companies. These treatments consist of small molecule drug products, biologics, cell-based therapies and traditional chemotherapy. Smaller and other early stage companies may also prove to be significant competitors. In addition, academic research departments and public and private research institutions may be conducting research on compounds that could prove to be competitive.

There are ~~also~~ several programs in development targeting SHP2, including those clinical programs run by Novartis AG, Jacobio Pharmaceuticals Co. Ltd./AbbVie Inc., and Relay Therapeutics Inc. There are several RAS pathway mutations programs, including those directed at KRAS^G12CG^12C(OFF) and KRAS^G12D(OFF)mutations, including clinical programs directed at KRAS^G12C(OFF) being conducted by Amgen Inc., Mirati Therapeutics, Inc., Johnson & Johnson, AstraZeneca plc and ~~Eli Lilly & Co.~~Genentech. Other clinical programs directed at mutant RAS are being conducted by Merck & Co./Moderna Therapeutics, Boehringer Ingelheim, ~~and~~ Gilead Sciences, Inc. and resTORbio.

Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer or less severe effects, are more convenient, have a broader label, are marketed more effectively, are reimbursed or are less expensive than any products that we may develop. Our competitors also may obtain FDA, EMA or other marketing approval for their products more rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market position before we are able to enter the market. Even if the product candidates we develop achieve marketing approval, they may be priced at a significant premium over competitive products if any have been approved by then, resulting in reduced competitiveness.

Smaller and other early stage companies may also prove to be significant competitors. In addition, academic research departments and public and private research institutions may be conducting research on compounds that could prove to be competitive. These thirdThird parties compete with us in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs. In addition, the biopharmaceutical industry is characterized by rapid technological change. If we fail to stay at the forefront of technological change, we may be unable to compete effectively. Technological advances or products developed by our competitors may render our product candidates obsolete, less competitive or not economical.

Even if we are able to commercialize any product candidates, such products may become subject to unfavorable pricing regulations or third-party coverage and reimbursement policies, which would harm our business.

The regulations that govern marketing approvals, pricing and reimbursement for new products vary widely from country to country. Some countries require approval of the sale price of a product before it can be marketed. In many countries, the pricing review period begins after marketing approval is granted. In some foreign markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. As a result, we might obtain marketing approval for a product candidate in a particular country, but then be subject to price regulations that delay our commercial launch of the product candidate, possibly for lengthy time periods, and negatively impact the revenues we are able to generate from the sale of the product candidate in that country. Adverse pricing limitations may hinder our ability to recoup our investment in one or more product candidates, even if our product candidates obtain marketing approval.

Our ability to commercialize any product candidates, whether as a single agent or combination therapy, successfully also will depend in part on the extent to which coverage and reimbursement for these product candidates and related treatments will be available from government authorities, private health insurers and other organizations. Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which medications they will pay for and establish reimbursement levels. It is difficult to predict at this time what government authorities and third-party payors will decide with respect to coverage and reimbursement for our programs.

A primary trend in the U.S. healthcare industry and elsewhere is cost containment. Government authorities and third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular products and requiring substitutions of generic products and/or biosimilars. Increasingly, third-party payors are requiring that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for drugs. We cannot be sure that coverage will be available for any product candidate that we commercialize and, if coverage is available, the level of reimbursement. These third-party payors are also examining the cost-effectiveness of drugs in addition to their safety and efficacy.

Reimbursement may impact the demand for, or the price of, any product candidate for which we obtain marketing approval. If reimbursement is not available or is available only to limited levels, we may not be able to successfully commercialize any product candidate for which we obtain marketing approval.

There may be significant delays in obtaining coverage and reimbursement for newly approved drugs, as the process is time-consuming and costly, and coverage may be more limited than the purposes for which the drug is approved by the FDA or comparable foreign regulatory authorities. Additionally, no uniform policy requirement for coverage and reimbursement for drug products exists among third-party payors in the United States, which may result in coverage and reimbursement for drug products that can differ significantly from payor to payor. Moreover, eligibility for reimbursement does not imply that any drug will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, sale and distribution. Interim reimbursement levels for new drugs, if applicable, may also not be sufficient to cover our costs and may not be made permanent. Reimbursement rates may vary according to the use of the drug and the clinical setting in which it is used, may be based on reimbursement levels already set for lower cost drugs and may be incorporated into existing payments for other services. Net prices for drugs may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the United States. Third-party payors often rely upon Medicare coverage policy and payment limitations in setting their own reimbursement policies. Our inability to promptly obtain coverage and profitable payment rates from both government-funded and private payors for any approved drugs that we develop could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize drugs and our overall financial condition.

We may fail to select or capitalize on the most scientifically, clinically and commercially promising or profitable mutant RAS(ON) target.

We have limited technical, managerial and financial resources to determine which of our lead generation stage RAS(ON) inhibitors should be advanced into further preclinical development, initial clinical trials, later-stage clinical development and potential commercialization. Initially, we are prioritizing four mutant RAS(ON) targets—KRAS^G12C, KRAS^G13C, KRAS^G12D and NRAS^G12C~~—and expect to nominate our first development candidate in 2020.~~. In selecting a development candidate, we may make incorrect determinations. Our decisions to allocate our research and development, management and financial resources toward particular development candidates or therapeutic areas may not lead to the development of viable commercial products and may divert resources from better opportunities. Similarly, our decisions to delay or terminate development programs may also be incorrect and could cause us to miss valuable opportunities.

We may not be successful in our efforts to identify or discover other product candidates and may fail to capitalize on programs or product candidates that may present a greater commercial opportunity or for which there is a greater likelihood of success.

The success of our business depends upon our ability to identify, develop and commercialize product candidates. If we do not successfully develop and eventually commercialize products, we will face difficulty in obtaining product revenue in future periods, resulting in significant harm to our financial position and adversely affecting our share price. Research programs to identify new product candidates require substantial technical, financial and human resources, and we may fail to identify potential product candidates for numerous reasons.

Additionally, because we have limited resources beyond those provided by Sanofi on SHP2 and RMC-4630, we may forego or delay pursuit of opportunities with certain programs or product candidates or for indications that later prove to have greater commercial potential. ~~For example, we currently intend to focus on the development of RMC-4630.~~ However, the advancement of this product candidate may ultimately prove to be unsuccessful or less successful than another program in our pipeline that we might have chosen to pursue on a less aggressive basis. Our estimates regarding the potential market for our product candidates could be inaccurate, and our spending on current and future research and development programs may not yield any commercially viable products. If we do not accurately evaluate the commercial potential for a particular product candidate, we may relinquish valuable rights to that product candidate through collaboration, licensing or other arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to such product candidate. For example, we licensed worldwide development and commercialization rights with respect to RMC-4630 to Sanofi and will receive only milestone payments, an equal share of profits and losses in the United States and royalties on annual net sales of each product outside the United States. Alternatively, we may allocate internal resources to a product candidate in a therapeutic area in which it would have been more advantageous to enter into a partnering arrangement.

If any of these events occur, we may be forced to abandon or delay our development efforts with respect to a particular product candidate or fail to develop a potentially successful product ~~candidate, which could have a material adverse effect on our business, financial condition, results of operations and prospects.~~candidate.

We may need to use existing commercial diagnostic tests or develop, or enter into a collaboration or partnership to develop, novel complementary diagnostics and/or novel companion diagnostics for some of our current or future product candidates. If we or our future partners are unable to successfully develop ~~such~~these companion diagnostics or complementary diagnostics, or experience significant delays in doing so, we may not realize the full commercial potential of our future product candidates.

As one of the key elements of our product development strategy, we seek to identify cancer patient populations that may derive meaningful benefit from our current or future product candidates. Because predictive biomarkers may be used to identify the right patients for our programs and our current or future product candidates, we believe that our success may depend, in part, on our ability to use existing diagnostic tests (such as Foundation Medicine’s FoundationOne^® CDX), or develop novel complementary diagnostics and/or novel companion diagnostics in collaboration with partners.

In the event that novel tests will need to be developed, we have little experience in the development of diagnostics. As such, we expect to rely on future partners in developing appropriate diagnostics to pair with our current or future product candidates. We ~~have not yet begun discussions with any potential partners with respect to the development of complementary diagnostics and/or companion diagnostics and~~ may be unsuccessful in entering into collaborations for the development of companion diagnostics for our programs and our current or future product candidates.

Complementary diagnostics and/or companion diagnostics are subject to regulation by the FDA and similar regulatory authorities outside the United States as medical devices and require separate regulatory approval or clearance prior to commercialization. If we, our partners, or any third parties that we engage to assist us, are unable to successfully develop complementary diagnostics and/or companion diagnostics for our product candidates and any future product candidates, or experience delays in doing so:

~~If any of these events were to occur, our business would be harmed, possibly materially.~~

We may seek and fail to obtain fast track or breakthrough therapy designations for our current or future product candidates. If we are successful, these programs may not lead to a faster development or regulatory review process, and they do not guarantee we will receive approval for any product candidate. We may also seek to obtain accelerated approval for one or more of our product candidates but the FDA may disagree that we have met the requirements for such approval.

If a product is intended for the treatment of a serious or life-threatening condition and preclinical or clinical data demonstrate the potential to address an unmet medical need for this condition, the product sponsor may apply for fast track designation. The FDA has broad discretion whether or not to grant this designation, so even if we believe a particular product candidate is eligible for this designation, ~~we cannot assure you that~~ the FDA ~~would decide to~~may reach a different conclusion and not grant it. Even if we do receive fast track designation, we may not experience a faster development process, review or approval compared to conventional FDA procedures. The FDA may rescind the fast track designation if it believes that the designation is no longer supported by data from our clinical development program.

We may also seek breakthrough therapy designation for any product candidate that we develop. A breakthrough therapy is defined as a drug that is intended, alone or in combination with one or more other drugs, to treat a serious or life-threatening disease or condition, and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over currently approved

therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. Like fast track designation, breakthrough therapy designation is within the discretion of the FDA. Accordingly, even if we believe a product candidate we develop meets the criteria for designation as a breakthrough therapy, the FDA may disagree and instead determine not to make such designation. In any event, the receipt of breakthrough therapy designation for a product candidate may not result in a faster development process, review or approval compared to drugs considered for approval under conventional FDA procedures and does not assure ultimate approval by the FDA. In addition, even if a product candidate we develop qualifies as a breakthrough therapy, the FDA may later decide that the drug no longer meets the conditions for qualification and rescind the designation.

Drugs designated as fast track products or breakthrough therapies by the FDA are also eligible for accelerated approval if the product has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity, or prevalence of the condition and the availability or lack of alternative treatments. As a condition of accelerated approval, the FDA will generally require the sponsor to perform adequate and well-controlled post-marketing clinical studies to verify and describe the anticipated effect on irreversible morbidity or mortality or other clinical benefit. In addition, the FDA requires pre-approval of promotional materials for accelerated approval products, once approved. We cannot guarantee that the FDA will agree any of our product candidates has met the criteria to receive accelerated approval, which would require us to conduct additional clinical testing prior to seeking FDA approval. Even if any of our product candidates received approval through this pathway, the product may fail required post-approval confirmatory clinical trials, and we may be required to remove the product from the market or amend the product label in a way that adversely impacts its marketing.

Jurisdictions where we may seek to pursue product candidates outside of the United States have processes similar to the breakthrough designation and fast track processes described above, and to the extent we desire to enter these markets, we will face similar risks and challenges as those described in the United States.

We may seek Orphan Drug Designation for product candidates we develop, and we may be unsuccessful or may be unable to maintain the benefits associated with Orphan Drug Designation, including the potential for market exclusivity.

As part of our business strategy, we may seek Orphan Drug Designation for ~~any~~ product candidates we ~~develop, and we may be unsuccessful.~~develop. Regulatory authorities in some jurisdictions, including the United States and Europe, may designate drugs for relatively small patient populations as orphan drugs. Under the Orphan Drug Act, the FDA may designate a drug as an orphan drug if it is a drug intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals annually in the United States, or a patient population greater than 200,000 in the United States where there is no reasonable expectation that the cost of developing the drug will be recovered from sales in the United States. In the United States, Orphan Drug Designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages and user-fee waivers.

Similarly, in Europe, the European Commission grants Orphan Drug Designation after receiving the opinion of the EMA Committee for Orphan Medicinal Products on an Orphan Drug Designation application. Orphan Drug Designation is intended to promote the development of drugs that are intended for the diagnosis, prevention or treatment of life-threatening or chronically debilitating conditions affecting not more than 5 in 10,000 persons in Europe and for which no satisfactory method of diagnosis, prevention, or treatment has been authorized (or the product would be a significant benefit to those affected). Additionally, designation is granted for drugs intended for the diagnosis, prevention, or treatment of a life-threatening, seriously debilitating or serious and chronic condition and when, without incentives, it is unlikely that sales of the drug in Europe would be sufficient to justify the necessary investment in developing the drug. In Europe, Orphan Drug Designation entitles a party to a number of incentives, such as protocol assistance and scientific advice specifically for designated orphan medicines, and potential fee reductions depending on the status of the sponsor.

Generally, if a drug with an Orphan Drug Designation subsequently receives the first marketing approval for the indication for which it has such designation, the drug is entitled to a period of marketing exclusivity, which precludes the EMA or the FDA from approving another marketing application for the same drug and indication for that time period, except in limited circumstances. The applicable period is seven years in the United States and ten years in Europe. The European exclusivity period can be reduced to six years if a drug no longer meets the criteria for Orphan Drug Designation or if the drug is sufficiently profitable such that market exclusivity is no longer justified.

~~Even~~We may be unsuccessful in obtaining Orphan Drug Designation for our product candidates. In addition, even if we obtain orphan drug exclusivity for a product candidate, that exclusivity may not effectively protect the product candidate from competition because different therapies can be approved for the same condition. Even after an orphan drug is approved, the FDA can subsequently approve the same drug for the same condition if the FDA concludes that the later drug is clinically superior in that it is shown to be safer, more effective or makes a major contribution to patient care. In addition, a designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which it received orphan designation. Moreover, orphan

drug exclusive marketing rights in the United States may be lost if the FDA later determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantity of the drug to meet the needs of patients with the rare disease or condition. Orphan Drug Designation neither shortens the development time or regulatory review time of a drug nor gives the drug any advantage in the regulatory review or approval process. While we may seek Orphan Drug Designation for applicable indications for our current and any future product candidates, we may never receive such designations. Even if we do receive such designations, there is no guarantee that we will enjoy the benefits of those designations.

If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit commercialization of any approved products.

We face an inherent risk of product liability as a result of the clinical testing of product candidates and will face an even greater risk if we commercialize any products. For example, we may be sued if any product candidate we develop causes or is perceived to cause injury or is found to be otherwise unsuitable during clinical testing, manufacturing, marketing or sale. Any such product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product, negligence, strict liability or a breach of warranties. Claims could also be asserted under state consumer protection acts. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit commercialization of any approved products. Even successful defense would require significant financial and management resources. Regardless of the merits or eventual outcome, liability claims may result in:

Our inability to obtain sufficient product liability insurance at an acceptable cost to protect against potential product liability claims could prevent or inhibit the commercialization of products we develop, alone or with collaboration partners.

Insurance coverage is increasingly expensive. We may not be able to maintain insurance at a reasonable cost or in an amount adequate to satisfy any liability that may arise, if at all. Our insurance policy contains various exclusions, and we may be subject to a product liability claim for which we have no coverage. We may have to pay any amounts awarded by a court or negotiated in a settlement that exceed our coverage limitations or that are not covered by our insurance, and we may not have, or be able to obtain, sufficient capital to pay such amounts. Even if our agreements with Sanofi or any future collaborator entitle us to indemnification against losses, such indemnification is limited and may not be available or adequate should any claim arise.

Healthcare legislative reform measures may have a material adverse effect on our business and results of operations.

In the United States, there have been and continue to be a number of legislative initiatives to contain healthcare costs. For example, in March 2010, the Affordable Care Act, or the ACA, was passed, which substantially changes the way healthcare is financed by both governmental and private insurers, and significantly impacts the U.S. pharmaceutical industry. The ACA, among other things, increases the minimum Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate Program and extends the rebate program to individuals enrolled in Medicaid managed care organizations, establishes annual fees and taxes on manufacturers of certain branded prescription drugs, and creates a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 70% point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D.

Some of the provisions of the ACA have yet to be fully implemented, while certain provisions have been subject to judicial and Congressional challenges, as well as efforts by the ~~Trump~~U.S. presidential administration to repeal or replace certain aspects of the ACA. ~~Since~~By way of example, in January ~~2017,~~2018, the President ~~Trump has~~ signed ~~two Executive Orders designed to delay~~a continuing resolution on appropriations for fiscal year 2018 that delayed the

implementation of certain ~~provisions of~~ACA-mandated fees, including the ~~ACA or otherwise circumvent some of~~so-called “Cadillac” tax on certain high cost employer-sponsored insurance plans, the ~~requirements for~~annual fee imposed on certain high cost employer-sponsored insurance plans, the annual fee imposed on certain health insurance ~~mandated by~~providers based on market share, and the ~~ACA. Concurrently, Congress has considered legislation that would repeal or repeal and replace all or part of~~medical device excise tax on non-exempt medical devices. In addition, the ~~ACA. While Congress has not passed comprehensive repeal legislation, two bills affecting the implementation of certain taxes under the ACA have been signed into law. The~~ Tax Cuts and Jobs Act, or the TCJA, includes a provision repealing, effective January 1, 2019, the tax-based shared responsibility payment imposed by the ACA on certain individuals who fail to maintain qualifying health coverage for all or part of a year that is commonly referred to as the “individual mandate.” Additionally, on January 22, 2018, President Trump signed a continuing resolution on appropriations for fiscal year 2018 that delayed the implementation of certain ACA-mandated fees, including the so-called “Cadillac” tax on certain high cost employer-sponsored insurance plans, the annual fee imposed on certain high cost employer-sponsored insurance plans, the annual fee imposed on certain health insurance providers based on market share, and the medical device excise tax on non-exempt medical devices. Further, the Bipartisan Budget Act of 2018, among other things, amends the ACA, effective January 1, 2019, to reduce the coverage gap in most Medicare drug plans, commonly referred to as the “donut hole.” OnIn December ~~14,~~ 2018, a Texas U.S. District Court Judge ruled that the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress as part of the TCJA. OnIn December ~~18,~~ 2019, the U.S. Court of Appeals for the 5th Circuit ruled that the individual mandate was unconstitutional and remanded the case back to the District Court to determine whether the remaining provisions of the ACA are invalid as well. OnIn March 2, 2020, the U.S. Supreme Court granted the petitions for writs of certiorari to review the case, although it is unclear when a decision will be made or how the Supreme Court will rule. In addition, there may be other efforts to challenge, repeal or replace the ACA. While the Texas U.S. District Court Judge, as well as the Trump administration and Centers for Medicare and Medicaid Services, or CMS, have stated that the ruling will have no immediate effect pending appeal of the decision, it is unclear how this decision, subsequent appeals, and other efforts to repeal and replace the ACA will impact the ACA and our business. The effect that the ACA and its possible repeal and replacement may have on our business remains unclear.

Other legislative changes have been proposed and adopted in the United States since the ACA was enacted. On August 2, 2011, the Budget Control Act of 2011, among other things, included aggregate reductions of Medicare payments to providers of 2% per fiscal year. These reductions went into effect on April 1, 2013 and, due to subsequent legislative amendments to the statute, will remain in effect through ~~2027~~2029 unless additional congressional action is taken. OnThe Coronavirus Aid, Relief and Economic Security Act, or CARES Act, which was signed into law in March 2020 and is designed to provide financial support and resources to individuals and businesses affected by the COVID-19 pandemic, suspended the 2% Medicare sequester from May 1, 2020 through December 31, 2020, and extended the sequester by one year, through 2030. In addition, in January 2, 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further reduced Medicare payments to several types of providers.

Moreover, payment methodologies may be subject to changes in healthcare legislation and regulatory initiatives. We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced demand for any product candidate we develop or complementary diagnostics or companion diagnostics or additional pricing pressures.

Additionally, there has been increasing legislative and enforcement interest in the United States with respect to specialty drug pricing practices. Specifically, there have been several recent U.S. Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to drug pricing, reduce the cost of prescription drugs under Medicare, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drugs.

We are subject to certain U.S. and foreign anti-corruption, anti-money laundering, export control, sanctions, and other trade laws and regulations. We can face serious consequences for violations.

Among other matters, U.S. and foreign anti-corruption, anti-money laundering, export control, sanctions, and other trade laws and regulations, which are collectively referred to as Trade Laws, prohibit companies and their employees, agents, clinical research organizations, legal counsel, accountants, consultants, contractors, and other partners from authorizing, promising, offering, providing, soliciting, or receiving directly or indirectly, corrupt or improper payments or anything else of value to or from recipients in the public or private sector. Violations of Trade Laws can result in substantial criminal fines and civil penalties, imprisonment, the loss of trade privileges, debarment, tax reassessments, breach of contract and fraud litigation, reputational harm, and other consequences. We have direct or indirect interactions with officials and employees of government agencies or government-affiliated hospitals, universities, and other organizations. We also expect our non-U.S. activities to increase in time. We plan to engage third parties for clinical trials and/or to obtain necessary permits, licenses, patent registrations, and other regulatory approvals and we can be held liable for the corrupt or other illegal activities of our personnel, agents, or partners, even if we do not explicitly authorize or have prior knowledge of such activities.

We are dependent on our collaboration with Sanofi for the development of RMC-4630 and may depend on Sanofi for the development and commercialization of any other future SHP2 inhibitor product candidates. Under certain circumstances, Sanofi may unilaterally terminate the collaboration for convenience, which would materially and adversely affect our business.

In June 2018, we entered into a collaborative research, development and commercialization agreement with Sanofi, or the Sanofi Agreement, focused on researching, developing and commercializing SHP2 inhibitors as cancer therapies and potentially other indications. Sanofi primarily controls the research and development activities pursuant to the terms of the Sanofi Agreement, and our lack of control over ~~such~~these activities, including with respect to RMC-4630, could result in delays or other difficulties in the development and commercialization of product candidates, which may prevent completion of intended NDA filings in a timely fashion, if at all. Because of the allocation of responsibilities under the Sanofi Agreement, we are wholly dependent on Sanofi for the success of the RMC-4630 program. Any dispute with Sanofi may result in the delay or termination of the research, development or

commercialization of RMC-4630 or other SHP2 inhibitor product candidates, and may result in costly litigation that diverts management attention and resources away from our day-to-day ~~activities, which may adversely affect our business, financial condition, results of operation and prospects.~~activities. For example, we plan to evaluate RMC-4630 in combination with other therapies (which may include product candidates from our pipeline), and Sanofi may disagree with us regarding which other therapies should be evaluated in combination with RMC-4630. As a result of this disagreement, our completion of a trial in combination with our preferred combination product candidate may be delayed or prevented. We rely on Sanofi for the supply of RMC-4630 for future combination studies and if Sanofi is unwilling to supply RMC-4630 to be used in combination with a product candidate from our pipeline or other products, our ability to complete a trial evaluating such combination may be delayed or prevented.

In addition, Sanofi can terminate the Sanofi Agreement (including for convenience), and in the event Sanofi terminates the Sanofi Agreement, we would be prevented from receiving any research and development funding, milestone payments, profit share payments, royalty payments and other benefits under that agreement. Termination of the Sanofi Agreement could require us to seek additional funding in order to avoid delaying, reducing the scope of, or suspending, one or more of our research and development programs or clinical trials. In addition, any decision by Sanofi to terminate the Sanofi Agreement may negatively impact public perception of RMC-4630, or all of the SHP2 program covered by the Sanofi ~~Agreement, which could adversely affect the market price of our common stock.~~Agreement. We cannot provide any assurance with respect to the success of the Sanofi collaboration. ~~Any of the foregoing events could have a materially adverse effect on our business, financial condition, results of operation and prospects.~~ For more information regarding the Sanofi Agreement, see Part I, Item 1 of our 2019 Form 10-K under the caption “Business—Collaboration agreement with Sanofi.”

In addition to our collaboration with Sanofi, we may depend on collaborations with other third parties for the development and commercialization of our product candidates in the future. If our collaborations are not successful, we may not be able to capitalize on the market potential of these product candidates.

In the future, we may form or seek other strategic alliances, joint ventures, or collaborations, or enter into additional licensing arrangements with third parties that we believe will complement or augment our development and commercialization efforts with respect to product candidates we develop.

Collaborations involving our current and future product candidates, including our current collaborations with Sanofi, Roche and Amgen may pose the following risks to us:

As a result, if we enter into additional collaboration agreements and strategic partnerships or license our intellectual property, products or businesses, we may not be able to realize the benefit of such transactions if we are unable to successfully integrate them with our existing operations, which could delay our timelines or otherwise adversely affect our business. We also cannot be certain that, following a strategic transaction or license, we will achieve the revenue or specific net income that justifies such transaction. Any delays in entering into new collaborations or strategic partnership agreements related to any product candidate we develop could delay

the development and commercialization of our product candidates, which would harm our business prospects, financial condition, and results of operations.

We may seek to establish additional collaborations, and, if we are not able to establish them on commercially reasonable terms, we may have to alter our development and commercialization plans.

The advancement of our product candidates and development programs and the potential commercialization of our current and future product candidates will require substantial additional cash to fund expenses. For some of our programs, we may decide to collaborate with additional pharmaceutical and biotechnology companies with respect to development and potential commercialization. Any of these relationships may require us to incur non-recurring and other charges, increase our near and long term expenditures, issue securities that dilute our existing stockholders, or disrupt our management and business.

We face significant competition in seeking appropriate strategic partners and the negotiation process is time-consuming and complex. Whether we reach a definitive agreement for other collaborations will depend, among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and the proposed collaborator’s evaluation of a number of factors. Those factors may include the design or results of clinical trials, the progress of our clinical trials, the likelihood of approval by the FDA or similar regulatory authorities outside the United States, the potential market for the subject product candidate, the costs and complexities of manufacturing and delivering such product candidate to patients, the potential of competing products, the existence of uncertainty with respect to our ownership of technology, which can exist if there is a challenge to such ownership without regard to the merits of the challenge and industry and market conditions generally. The collaborator may also consider alternative product candidates or technologies for similar indications that may be available to collaborate on and whether such a collaboration could be more attractive than the one with us for our product candidate. Further, we may not be successful in our efforts to establish a strategic partnership or other alternative arrangements for future product candidates because they may be deemed to be at too early of a stage of development for collaborative effort and third parties may not view them as having the requisite potential to demonstrate safety and efficacy.

We may also be restricted under existing collaboration agreements from entering into future agreements on certain terms with potential collaborators. For example, under the Sanofi Agreement, we have granted worldwide exclusive rights under our intellectual property to Sanofi for SHP2 inhibitors, and during the term of the agreement we will be restricted from granting similar rights to other parties. This exclusivity could limit our ability to enter into collaborations with future collaborators.

In addition, there have been a significant number of recent business combinations among large pharmaceutical companies that have resulted in a reduced number of potential future collaborators.

We may not be able to negotiate collaborations on a timely basis, on acceptable terms, or at all. If we are unable to do so, we may have to curtail the development of the product candidate for which we are seeking to collaborate, reduce or delay its development program or one or more of our other development programs, delay its potential commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake development or commercialization activities at our own expense. If we elect to increase our expenditures to fund development or commercialization activities on our own, we may need to obtain additional capital, which may not be available to us on acceptable terms or at all. If we do not have sufficient funds, we may not be able to further develop our product candidates or bring them to market and generate product revenue.

If conflicts arise between us and our collaborators or strategic partners, these parties may act in a manner adverse to us and could limit our ability to implement our strategies.

If conflicts arise between our corporate or academic collaborators or strategic partners and us, the other party may act in a manner adverse to us and could limit our ability to implement our strategies. Sanofi or future collaborators or strategic partners may develop, either alone or with others, products in related fields that are competitive with the products or potential products that are the subject of these collaborations. Competing products, either developed by the collaborators or strategic partners or to which the collaborators or strategic partners have rights, may result in the withdrawal of partner support for our product candidates. Our current or future collaborators or strategic partners may preclude us from entering into collaborations with their competitors, fail to obtain timely regulatory approvals, terminate their agreements with us prematurely, or fail to devote sufficient resources to the development and commercialization of products. Any of these developments could harm our product development efforts.

We rely on third parties to conduct our ongoing and planned clinical trials for RMC-4630 and any other product candidates we develop. If these third parties do not successfully carry out their contractual duties, comply with regulatory requirements or meet expected deadlines, we may not be able to obtain marketing approval for or commercialize RMC-4630 and any other product candidates we ~~develop and our business could be substantially harmed.~~develop.

We do not have the ability to independently conduct clinical trials. We rely on medical institutions, clinical investigators, contract laboratories, and other third parties, including collaboration partners, to conduct or otherwise support clinical trials for RMC-4630 and other product candidates. We rely heavily on these parties for execution of clinical trials and control only certain aspects of their activities. Nevertheless, we are responsible for ensuring that each of our clinical trials is conducted in accordance with the applicable protocol, legal and regulatory requirements and scientific standards, and our reliance on CROs will not relieve us of our regulatory responsibilities. For any violations of laws and regulations during the conduct of our clinical trials, we could be subject to untitled and warning letters or enforcement action that may include civil penalties up to and including criminal prosecution.

We and third parties are required to comply with regulations and requirements, including GCP, for conducting, monitoring, recording and reporting the results of clinical trials to ensure that the data and results are scientifically credible and accurate, and that the trial patients are adequately informed of the potential risks of participating in clinical trials and their rights are protected. These regulations are enforced by the FDA, the Competent Authorities of the Member States of the EEA and comparable foreign regulatory authorities for any drugs in clinical development. The FDA enforces GCP requirements through periodic inspections of clinical trial sponsors, principal investigators and trial sites. If we or third parties fail to comply with applicable GCP, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or comparable foreign regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. ~~We cannot assure you that, upon~~Upon inspection, the FDA ~~will~~may determine that any of our current or future clinical trials ~~will~~do not comply with GCP. In addition, our clinical trials must be conducted with product candidates produced under cGMP regulations. Our failure or the failure of third parties to comply with these regulations may require us to repeat clinical trials, which would delay the marketing approval process and could also subject us to enforcement action. We also are required to register certain ongoing clinical trials and provide certain information, including information relating to the trial’s protocol, on a government-sponsored database, ClinicalTrials.gov, within specific timeframes. Failure to do so can result in fines, adverse publicity and civil and criminal sanctions.

Although we intend to design the clinical trials for our product candidates, or be involved in the design when other parties sponsor the trials, third parties conduct all of the clinical trials. For example, Amgen ~~will conduct~~is conducting the ~~planned~~ Phase 1b trial evaluating the combination of RMC-4630 and ~~AMG 510.~~sotorasib and Sanofi is conducting the Phase 1 trial evaluating the combination of RMC-4630 and pembrolizumab. In addition, in March 2020, the Pancreatic Cancer Collective (a strategic partnership between Lustgarten Foundation and Stand Up To Cancer) announced that it had awarded funding to the Netherlands Cancer Institute for its study using RMC-4630 in combination with an investigational ERK inhibitor (LY3214996) in patients with pancreatic cancer. We plan to provide RMC-4630 to support this investigator sponsored study. As a result, many important aspects of our clinical development, including their conduct and timing, will be outside of our direct control. Our reliance on third parties to conduct future clinical trials will also result in less direct control over the management of data developed through clinical trials than would be the case if we were relying entirely upon our own staff. Communicating with outside parties can also be challenging, potentially leading to mistakes as well as difficulties in coordinating activities. Outside parties may:

These factors may materially adversely affect the willingness or ability of third parties to conduct our clinical trials and may subject us to unexpected cost increases that are beyond our control. If the CROs do not perform clinical trials in a satisfactory manner, breach their obligations to us or fail to comply with regulatory requirements, the development, marketing approval and commercialization of our product candidates may be delayed, we may not be able to obtain marketing approval and commercialize our product candidates, or our development program may be materially and irreversibly harmed. If we are unable to rely on clinical data collected by our CROs, we could be required to repeat, extend the duration of, or increase the size of any clinical trials we conduct and this could significantly delay commercialization and require significantly greater expenditures.

If any of our relationships with these third-party CROs terminate, we may not be able to enter into arrangements with alternative CROs on commercially reasonable terms, or at all. If CROs do not successfully carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or if the quality or accuracy of the clinical data they obtain are compromised due

to the failure to adhere to our clinical protocols, regulatory requirements or for other reasons, any clinical trials such CROs are associated with may be extended, delayed or terminated, and we may not be able to obtain marketing approval for or successfully commercialize our product candidates. As a result, we believe that our financial results and the commercial prospects for our product candidates in the subject indication would be harmed, our costs could increase and our ability to generate revenue could be delayed.

We rely on third parties to manufacture preclinical and clinical drug supplies, and we intend to rely on third parties to produce commercial supplies of any approved product, which increases the risk that we will not have sufficient quantities of ~~such~~these product candidates or products or such quantities at an acceptable cost, which could delay, prevent or impair our development or commercialization efforts.

We do not own or operate manufacturing facilities for the production of preclinical, clinical or commercial supplies of the product candidates that we are developing or evaluating in our development programs. We have limited personnel with experience in drug manufacturing and lack the resources and the capabilities to manufacture any of our product candidates on a preclinical, clinical or commercial scale. We rely on third parties for supply of our preclinical and clinical drug supplies (including key starting and intermediate materials), and our strategy is to outsource all manufacturing of our product candidates and products to third parties, including Sanofi.

In order to conduct clinical trials of product candidates, we will need to have them manufactured in potentially large quantities. Our third-party manufacturers may be unable to successfully increase the manufacturing capacity for any of our clinical drug supplies (including key starting and intermediate materials) in a timely or cost-effective manner, or at all. In addition, quality issues may arise during scale-up activities and at any other time. For example, ongoing data on the stability of our product candidates may shorten the expiry of our product candidates and lead to clinical trial material supply shortages, and potentially clinical trial delays. If these third-party manufacturers are unable to successfully scale up the manufacture of our product candidates in sufficient quality and quantity, the development, testing and clinical trials of that product candidate may be delayed or infeasible, and regulatory approval or commercial launch of that product candidate may be delayed or not ~~obtained, which could significantly harm our business.~~obtained.

Our use of new third-party manufacturers increases the risk of delays in production or insufficient supplies of our product candidates (and the key starting and intermediate materials for such product candidates) as we transfer our manufacturing technology to these manufacturers and as they gain experience manufacturing our product candidates (and the key starting and intermediate materials for such product candidates).

Even after a third-party manufacturer has gained significant experience in manufacturing our product candidates (or the key starting and intermediate materials for such product candidates) or even if we believe we have succeeded in optimizing the manufacturing process, there can be no assurance that such manufacturer will produce sufficient quantities of our product candidates (or the key starting and intermediate materials for such product candidates) in a timely manner or continuously over time, or at all.

We may be delayed if we need to change the manufacturing process used by a third party. Further, if we change an approved manufacturing process, then we may be delayed if the FDA or a comparable foreign authority needs to review the new manufacturing process before it may be used.

We do not currently have any agreements with third-party manufacturers for long-term commercial supply. In the future, we may be unable to enter into agreements with third-party manufacturers for commercial supplies of any product candidate that we develop, or may be unable to do so on acceptable terms. Even if we are able to establish and maintain arrangements with third-party manufacturers, reliance on third-party manufacturers entails risks, including:

Third-party manufacturers may not be able to comply with cGMP requirements or similar regulatory requirements outside the United States. Our failure, or the failure of our third-party manufacturers, to comply with applicable requirements could result in sanctions being imposed on us, including fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of product candidates or products, operating restrictions and/or criminal prosecutions, any of which could significantly and adversely affect supplies of our product candidates.

Our future product candidates and any products that we may develop may compete with other product candidates and products for access to manufacturing facilities. There are a limited number of manufacturers that operate under cGMP requirements particularly for the development of monoclonal antibodies, and that might be capable of manufacturing for us.

If the third parties that we engage to supply any materials or manufacture product for our preclinical tests and clinical trials should cease to continue to do so for any reason, we likely would experience delays in advancing these tests and trials while we identify and qualify replacement suppliers or manufacturers and we may be unable to obtain replacement supplies on terms that are favorable to us. In addition, if we are not able to obtain adequate supplies of our product candidates or the substances used to manufacture them, it will be more difficult for us to develop our product candidates and compete effectively.

Some of our third-party manufacturers which we use for the supply of materials for product candidates or other materials necessary to manufacture product to conduct clinical trials are located in countries affected by COVID-19, and should they experience disruptions, such as temporary closures or suspension of services, we would likely experience delays in advancing these trials. ~~Currently, we expect no material impact on the clinical supply of RMC-4630.~~

Our current and anticipated future dependence upon others for the manufacture of our product candidates (or the key starting and intermediate materials for such product candidates) may adversely affect our future profit margins and our ability to develop product candidates and commercialize any products that receive marketing approval on a timely and competitive basis.

Our future relationships with customers and third-party payors in the United States and elsewhere may be subject, directly or indirectly, to applicable anti-kickback, fraud and abuse, false claims, transparency, health information privacy and security and other healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm, administrative burdens and diminished profits and future earnings.

Healthcare providers, physicians and third-party payors in the United States and elsewhere will play a primary role in the recommendation and prescription of any product candidates for which we obtain marketing approval. Our future arrangements with third-party payors and customers may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations, including, without limitation, the federal Anti-Kickback Statute and the federal False Claims Act, or FCA, which may constrain the business or financial arrangements and relationships through which we sell, market and distribute any products for which we obtain marketing approval. In addition, we may be subject to transparency laws and patient privacy regulation by the U.S. federal and state governments and by governments in foreign jurisdictions in which we conduct our business. The applicable federal, state and foreign healthcare laws and regulations that may affect our ability to operate include:

analogous or related foreign, state or local laws and regulations, including anti-kickback and false claims laws, which may apply to sales or marketing arrangements and claims involving healthcare items or services reimbursed by non-governmental third-party payors, including private insurers; laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government or otherwise restrict payments that may be made to healthcare providers; laws that require drug manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers or marketing expenditures; and healthcare and data protection laws in the European Union and other jurisdictions, including reporting requirements detailing interactions with and payments to healthcare providers and laws governing the privacy and security of certain protected information, such as theCalifornia Consumer Privacy Act, or CCPA, which creates individual privacy rights for California consumers and increases the privacy and security obligations of entities handling certain personal data, and General Data Protection Regulation, or GDPR, which imposes obligations and restrictions on the collection and use of personal data relating to individuals located in the European Economic Area, or the EEA, and the United Kingdom (including health data).

•

analogous state laws and regulations, such as state anti-kickback and false claims laws, which may apply to sales or marketing arrangements and claims involving healthcare items or services reimbursed by non-governmental third-party payors, including private insurers; state laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government or otherwise restrict payments that may be made to healthcare providers; state laws that require drug manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers or marketing expenditures; and healthcare and data protection laws in the European Union and other jurisdictions, including reporting requirements detailing interactions with and payments to healthcare providers and laws governing the privacy and security of certain protected information, such as the General Data Protection Regulation, or GDPR, which imposes obligations and restrictions on the collection and use of personal data relating to individuals located in the European Economic Area, or the EEA, and the United Kingdom (including health data).

Because of the breadth of ~~these~~the laws described above and the narrowness of the statutory exceptions and regulatory safe harbors available under ~~such laws,~~them, it is possible that some of our business activities could be subject to challenge under one or more of ~~such~~these laws. The scope and enforcement of each of these laws is uncertain and subject to rapid change in the current environment of healthcare reform, especially in light of the lack of applicable precedent and regulations. Federal and state enforcement bodies have recently increased their scrutiny of interactions between healthcare companies and healthcare providers, which has led to a number of investigations, prosecutions, convictions and settlements in the healthcare industry. Ensuring that our business arrangements with third parties comply with applicable healthcare laws, as well as responding to investigations by government authorities, can be time- and resource-consuming and can divert management’s attention from the business.

If our operations are found to be in violation of any of the laws described above or any other government regulations that apply to us, we may be subject to penalties, including civil, criminal and administrative penalties, damages, fines, disgorgement, individual imprisonment, possible exclusion from participation in federal and state funded healthcare programs, contractual damages and the curtailment or restricting of our operations, as well as additional reporting obligations and oversight if we become subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws, any of which could harm our ability to operate our business and our financial results. Further, if the physicians or other providers or entities with whom we expect to do business are found not to be in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs. In addition, the approval and commercialization of any product candidate we develop outside the United States will also likely subject us to foreign equivalents of the healthcare laws mentioned above, among other foreign laws.

Risks Related to Intellectual Property

If we and our collaborators are unable to obtain and maintain sufficient patent and other intellectual property protection for our product candidates and technology, our competitors could develop and commercialize products and technology similar or identical to ours, and we may not be able to compete effectively in our market or successfully commercialize any product candidates we may develop.

Our success depends in significant part on our ability and the ability of our collaborators to obtain, maintain, enforce and defend patents and other intellectual property rights with respect to our product candidates and technology and to operate our business without infringing, misappropriating, or otherwise violating the intellectual property rights of others. If we and our collaborators are unable to obtain and maintain sufficient intellectual property protection for RMC-4630 or other product candidates that we may identify, or if the scope of the intellectual property protection obtained is not sufficiently broad, our competitors and other third parties could develop and commercialize product candidates similar or identical to ours, and our ability (and the ability of our collaborators) to successfully commercialize RMC-4630 and other product candidates that we (and our collaborators) may pursue may be impaired. We ~~do not~~ have ~~any~~one issued ~~patents~~patent with respect to our SHP2 program, including RMC-4630, and we can provide no assurance that any of our current or future patent applications will result in issued patents or that any issued patents will provide us with any competitive advantage. Failure to obtain such issued patents could have a material adverse effect on our and Sanofi’s ability to develop and commercialize SHP2 inhibitor products, including RMC-4630, and on our ability to receive milestone, royalty or other payments from Sanofi pursuant to the Sanofi Agreement.

We seek to protect our proprietary positions by, among other things, filing patent applications in the United States and abroad related to RMC-4630 or other product candidates that we may identify. Obtaining, maintaining, defending and enforcing pharmaceutical patents is costly, time consuming and complex, and we may not be able to file and prosecute all necessary or desirable patent applications, or maintain, enforce and license any patents that may issue from such patent applications, at a reasonable cost or in a timely manner. It is also possible that we will fail to identify patentable aspects of our research and development output before it is too late to obtain patent protection. We may not have the right to control the preparation, filing, prosecution and maintenance of patent applications, or to maintain the rights to patents licensed to or from third parties.

Although we enter into confidentiality agreements with parties who have access to confidential or patentable aspects of our research and development output, such as our employees, collaborators, CROs, contract manufacturers, consultants, advisors and other third parties, any of these parties may breach the agreements and disclose such output before a patent application is filed, thereby jeopardizing our ability to seek patent protection. Further, we may not be aware of all third-party intellectual property rights potentially relating to our product candidates. Publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after filing or, in some cases, not at all. Therefore, we cannot know with certainty whether we were the first to make the inventions claimed in our patents or pending patent applications, or that we were the first to file for patent protection of such inventions.

The patent position of pharmaceutical companies generally is highly uncertain, involves complex legal, technological and factual questions and has, in recent years, been the subject of much debate and litigation throughout the world. In addition, the laws of foreign countries may not protect our rights to the same extent as the laws of the United States, or vice versa. As a result, the issuance, scope, validity, enforceability, and commercial value of our patent rights are highly uncertain. The subject matter claimed in a patent application can be significantly reduced before the patent is issued, and its scope can be reinterpreted after issuance. Therefore, our pending and future patent applications may not result in patents being issued in relevant jurisdictions that protect our product candidates, in whole or in part, or which effectively prevent others from commercializing competitive product candidates, and even if our patent applications issue as patents in relevant jurisdictions, they may not issue in a form that will provide us with any meaningful protection for our product candidates or technology, prevent competitors from competing with us or otherwise provide us with any competitive advantage. Additionally, our competitors may be able to circumvent our patents by developing similar or alternative product candidates or technologies in a non-infringing manner.

The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and our patents may be challenged in the courts or patent offices in the United States and abroad. We may be subject to a third-party preissuance submission of prior art to the United States Patent and Trademark Office, or the USPTO, or become involved in opposition, derivation, revocation, reexamination, inter partes review, post-grant review or interference proceedings challenging our patent rights or the patent rights of others, or other proceedings in the USPTO or applicable foreign offices that challenge priority of invention or other features of patentability. An adverse determination in any such submission, proceeding or litigation could result in loss of exclusivity or freedom to operate, patent claims being narrowed, invalidated or held unenforceable, in whole or in part, limit the scope or duration of the patent protection of our product candidates, all of which could limit our ability to stop others from using or commercializing similar or identical product candidates or technology to compete directly with us, without payment to us, or result in our inability to manufacture or commercialize products without infringing third-party patent rights. In addition, if the breadth or strength of protection provided by our patents and patent applications is threatened, regardless of the outcome, it could dissuade companies from collaborating with us to license, develop or commercialize current or future product candidates, or could have a material adverse effect

on our ability to raise funds necessary to continue our research programs or clinical trials. Such proceedings also may result in substantial cost and require significant time from our scientists and management, even if the eventual outcome is favorable to us.

In addition, given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. As a result, our patent portfolio may not provide us with sufficient rights to exclude others from commercializing products or technology similar or identical to ours for a meaningful amount of time, or at all. Moreover, some of our owned or licensed patents and patent applications are, and may in the future be, co-owned with third parties. If we are unable to obtain exclusive licenses to any such co-owners’ interest in such patents or patent applications, such co-owners may be able to license their rights to other third parties, including our competitors, and our competitors could market competing products and technology. In addition, we may need the cooperation of any such co-owners in order to enforce such patents against third parties, and such cooperation may not be provided to us. Any of the foregoing could harm our competitive position, business, financial condition, results of operations and prospects.

We have entered into licensing agreements with third parties. If we or a third party fail to comply with our obligations in the agreements under which we license intellectual property rights to or from third parties, or these agreements are terminated, or we otherwise experience disruptions to our business relationships with our licensors or licensees, our competitive position, business, financial condition, results of operations and prospects could be harmed.

In addition to patent and other intellectual property rights we own or co-own, we have licensed, and may in the future license, patent and other intellectual property rights to and from other parties. Licenses may not provide us with exclusive rights to use the applicable intellectual property and technology in all relevant fields of use and in all territories in which we may wish to develop or commercialize our products and technology in the future. As a result, we may not be able to prevent competitors from developing and commercializing competitive products or technologies.

In addition, in some circumstances, we may not have the right to control the preparation, filing and prosecution of patent applications or to maintain, defend and enforce the patents that we license to or from third parties, and we may have to rely on our partners to fulfill these responsibilities. For example, in June 2018, we entered into the Sanofi Agreement, wherein we exclusively licensed the worldwide rights in our SHP2 inhibitor program, including RMC-4630, to Sanofi. Although we have review and comment rights regarding patent prosecution decisions, Sanofi retains ultimate decision-making control, as well as the sole and exclusive right to enforce infringement of or defend claims against patents that relate to SHP2 inhibitor products licensed to it pursuant to the Sanofi Agreement. Consequently, any such licensed patents and applications may not be prepared, filed, prosecuted, maintained, enforced, and defended in a manner consistent with the best interests of our business. If our current or future licensors, licensees or collaborators fail to prepare, file, prosecute, maintain, enforce, and defend licensed patents and other intellectual property rights, such rights may be reduced or eliminated, and our right to develop and commercialize any of our product candidates or technology that are the subject of such licensed rights could be adversely affected. In addition, our licensors may own or control intellectual property that has not been licensed to us and, as a result, we may be subject to claims, regardless of their merit, that we are infringing or otherwise violating the licensor’s rights.

If we fail to comply with our obligations in the agreements under which we license intellectual property rights from third parties, the licensor may have the right to terminate the license. If these agreements are terminated, the underlying patents fail to provide the intended exclusivity or we otherwise experience disruptions to our business relationships with our licensors, we could lose intellectual property rights that are important to our business or be prevented from developing and commercializing our product candidates, and competitors could have the freedom to seek regulatory approval of, and to market, products identical to ours. Termination of these agreements or reduction or elimination of our rights under these agreements may also result in our having to negotiate new or reinstated agreements with less favorable terms, cause us to lose our rights under these agreements, including our rights to important intellectual property or technology, or impede, delay or prohibit the further development or commercialization of one or more product candidates that rely on such agreements. It is possible that we may be unable to obtain any additional licenses at a reasonable cost or on reasonable terms, if at all. In that event, we may be required to expend significant time and resources to redesign our product candidates or the methods for manufacturing them or to develop or license replacement technology, all of which may not be feasible on a technical or commercial basis.

In addition, the research resulting in certain of our owned and in-licensed patent rights and technology was funded in part by the U.S. federal or state governments. As a result, the government may have certain rights, including march-in rights, to such patent rights and technology. When new technologies are developed with government funding, the government generally obtains certain rights in any resulting patents, including a non-exclusive license authorizing the government to use the invention for noncommercial purposes. These rights may permit the government to disclose our confidential information to third parties or allow third parties to use our licensed technology. The government can exercise its march-in rights if it determines that action is necessary because we fail to achieve practical application of the government-funded technology, because action is necessary to alleviate health or safety needs, to meet requirements of federal regulations, or to give preference to U.S. industry. In addition, our rights in such inventions may be

subject to certain requirements to manufacture products embodying such inventions in the United States. Any of the foregoing could harm our competitive position, business, financial condition, results of operations and prospects.

Licensing of intellectual property is of critical importance to our business and involves complex legal, business and scientific issues and certain provisions in intellectual property license agreements may be susceptible to multiple interpretations. Disputes may arise between us and our licensing partners regarding intellectual property subject to a license agreement, including:

the scope of rights granted under the license agreement and other interpretation-related issues;

whether and the extent to which technology and processes of one party infringe on intellectual property of the other party that are not subject to the licensing agreement;

rights to sublicense patent and other rights to third parties;

any diligence obligations with respect to the use of the licensed technology in relation to development and commercialization of our product candidates, and what activities satisfy those diligence obligations;

the ownership of inventions and know-how resulting from the joint creation or use of intellectual property;

rights to transfer or assign the license; and

the effects of termination.

The resolution of any contract interpretation disagreement that may arise could narrow what we believe to be the scope of our rights to the relevant intellectual property or technology, or increase what we believe to be our financial or other obligations under the relevant agreement, either of which could harm our business, financial condition, results of operations and prospects. Moreover, if disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrangements on acceptable terms, we may be unable to successfully develop and commercialize the affected product candidates.

In addition, if our licensors or licensees fail to abide by the terms of the license, if the licensors or licensees fail to prevent infringement by third parties or if the licensed patents or other rights are found to be invalid or unenforceable, our business, competitive position, financial condition, results of operations and prospects could be materially harmed.

For more information regarding our license agreements, see Part I, Item 1 of our 2019 Form 10-K under the caption “Business—Collaboration agreement with Sanofi.” ~~Any of the foregoing could harm our competitive position, business, financial condition, results of operations and prospects.~~

If we are unable to obtain licenses from third parties on commercially reasonable terms or at all, our business could be harmed.

It may be necessary for us to use the patented or proprietary technology of third parties to commercialize our products, in which case we would be required to obtain a license from these third parties. The licensing of third-party intellectual property rights is a competitive area, and more established companies may pursue strategies to license or acquire third-party intellectual property rights that we may consider attractive or necessary. More established companies may have a competitive advantage over us due to their size, capital resources and greater clinical development and commercialization capabilities. In addition, companies that perceive us to be a competitor may be unwilling to assign or license rights to us. We also may be unable to license or acquire third party intellectual property rights on terms that would allow us to make an appropriate return on our investment or at all. If we are unable to license ~~such~~needed technology, or if we are forced to license ~~such~~this technology on unfavorable terms, our business could be materially harmed. If we are unable to obtain a necessary license, we may be unable to develop or commercialize the affected product candidates, ~~which could materially harm our business,~~ and the third parties owning such intellectual property rights could seek either an injunction prohibiting our sales, or, with respect to our sales, an obligation on our part to pay royalties or other forms of compensation. Even if we are able to obtain a license, it may be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. ~~Any of the foregoing could harm our competitive position, business, financial condition, results of operations and prospects.~~

We may not identify relevant third-party patents or may incorrectly interpret the relevance, scope or expiration of a third-party patent, which might subject us to infringement claims or adversely affect our ability to develop and market our product candidates.

We cannot guarantee that any of our or our licensors’ patent searches or analyses, including the identification of relevant patents, the scope of patent claims or the expiration of relevant patents, are complete or thorough, nor can we be certain that we have identified each and every third-party patent and pending patent application in the United States and abroad that is relevant to or necessary for the commercialization of our product candidates in any jurisdiction. For example, U.S. patent applications filed before November 29, 2000 and certain U.S. patent applications filed after that date that will not be filed outside the United States remain confidential until patents issue. ~~As mentioned above, patent~~Patent applications in the United States and elsewhere are published approximately 18 months after the earliest filing for which priority is claimed, with ~~such~~the earliest filing date being commonly referred to as the priority date. Therefore, patent applications covering our product candidates could have been filed by third parties without our knowledge. Additionally, pending patent applications that have been published can, subject to certain limitations, be later amended in a manner that could cover our product candidates or the use of our product candidates. The scope of a patent claim is determined by an interpretation of the law, the written disclosure in a patent and the patent’s prosecution history. Our interpretation of the relevance or the scope of a patent or a pending application may be incorrect, which may negatively impact our ability to market our product candidates. We may incorrectly

determine that our product candidates are not covered by a third-party patent or may incorrectly predict whether a third party’s pending application will issue with claims of relevant scope. Our determination of the expiration date of any patent in the United States or abroad that we consider relevant may be incorrect, which may negatively impact our ability to develop and market our product candidates. Our failure to identify and correctly interpret relevant patents may negatively impact our ability to develop and market our product candidates.

If we fail to identify and correctly interpret relevant patents, we may be subject to infringement claims. We cannot guarantee that we will be able to successfully settle or otherwise resolve ~~such~~any infringement claims. If we fail in any ~~such dispute,~~of these disputes, in addition to being forced to pay damages, which may be significant, we may be temporarily or permanently prohibited from commercializing any of our product candidates that are held to be infringing. We might, if possible, also be forced to redesign product candidates so that we no longer infringe the third-party intellectual property rights. Any of these events, even if we were ultimately to prevail, could require us to divert substantial financial and management resources that we would otherwise be able to devote to our ~~business and could adversely affect our business, financial condition, results of operations and prospects.~~business.

Patent terms may be inadequate to protect our competitive position on our product candidates for an adequate amount of time.

Patents have a limited lifespan. In the United States, if all maintenance fees are timely paid, the natural expiration of a patent is generally 20 years from its earliest U.S. non-provisional filing date. Various extensions may be available, but the life of a patent, and the protection it affords, is limited. Even if patents covering our product candidates are obtained, once the patent life has expired for a product candidate, we may be open to competition from competitive medications, including generic medications. Given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such product candidates might expire before or shortly after such product candidates are commercialized. As a result, our owned and licensed patent portfolio may not provide us with sufficient rights to exclude others from commercializing product candidates similar or identical to ours for a meaningful amount of time, or at all.

Depending upon the timing, duration and conditions of any FDA marketing approval of our product candidates, one or more of our owned or licensed U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman Amendments, and similar legislation in the European Union and certain other countries. The Hatch-Waxman Amendments permit a patent term extension of up to five years for a patent covering an approved product as compensation for effective patent term lost during product development and the FDA regulatory review process. However, we may not receive an extension if we fail to exercise due diligence during the testing phase or regulatory review process, fail to apply within applicable deadlines, fail to apply prior to expiration of relevant patents or otherwise fail to satisfy applicable requirements. Moreover, the length of the extension could be less than we request. Only one patent per approved product can be extended, the extension cannot extend the total patent term beyond 14 years from approval and only those claims covering the approved drug, a method for using it or a method for manufacturing it may be extended. If we are unable to obtain patent term extension or the term of any such extension is less than we request, the period during which we can enforce our patent rights for the applicable product candidate will be shortened and our competitors may obtain approval to market competing products sooner. As a result, our revenue from applicable products could be reduced. Further, if this occurs, our competitors may take advantage of our investment in development and trials by referencing our clinical and preclinical data and launch their product earlier than might otherwise be the ~~case, and our competitive position, business, financial condition, results of operations and prospects could be materially harmed.~~case.

Also, there are detailed rules and requirements regarding the patents that may be submitted to the FDA for listing in the Approved Drug Products with Therapeutic Equivalence Evaluations, or the Orange Book. We may be unable to obtain patents covering our product candidates that contain one or more claims that satisfy the requirements for listing in the Orange Book. Even if we submit a patent for listing in the Orange Book, the FDA may decline to list the patent, or a manufacturer of generic drugs may challenge the listing. If one of our product candidates is approved and a patent covering that product candidate is not listed in the Orange Book, a manufacturer of generic drugs would not have to provide advance notice to us of any abbreviated new drug application filed with the FDA to obtain permission to sell a generic version of such product candidate. ~~Any of the foregoing could harm our competitive position, business, financial condition, results of operations and prospects.~~

We may not be able to protect our intellectual property rights throughout the world.

Filing, prosecuting, maintaining, defending and enforcing patents on our product candidates in all countries throughout the world would be prohibitively expensive, and our intellectual property rights in some countries outside the United States can be less extensive than those in the United States. In addition, the laws and enforcement practices of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the United States. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the United States, or from selling or importing products made using our inventions in and into the United States or other jurisdictions. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and may export otherwise infringing products to territories where we have patent protection, but enforcement rights are not as strong as those in the United States. These products may compete with our product candidates and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of some countries do not favor the enforcement or protection of patents, trade secrets and other intellectual property, which could make it difficult for us to stop the infringement of our patents or marketing of competing products in violation of our intellectual property and proprietary rights generally. Proceedings to enforce our intellectual property rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded, if any, may not be commercially meaningful.

Many foreign countries, including some European Union countries, India, Japan and China, have compulsory licensing laws under which a patent owner may be compelled under specified circumstances to grant licenses to third parties. In addition, many countries limit the enforceability of patents against government agencies or government contractors. In those countries, we may have limited remedies if patents are infringed or if we are compelled to grant a license to a third party, which could materially diminish the value of the applicable patents. This could limit our potential revenue opportunities. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or ~~license, which could adversely affect our business, financial condition, results of operations and prospects.~~license.

Changes in patent law could diminish the value of patents in general, thereby impairing our ability to protect our product candidates.

Obtaining and enforcing patents in the pharmaceutical industry is inherently uncertain, due in part to ongoing changes in the patent laws. For example, in the United States, depending on decisions by Congress, the federal courts, and the USPTO, the laws and regulations governing patents, and interpretation thereof, could change in unpredictable ways that could weaken our and our licensors’ or collaborators’ ability to obtain new patents or to enforce existing or future patents. For example, the U.S. Supreme Court has ruled on several patent cases in recent years, either narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations. Therefore, there is increased uncertainty with regard to our and our licensors’ or collaborators’ ability to obtain patents in the future, as well as uncertainty with respect to the value of patents once obtained.

~~Recent patent~~Patent reform legislation could increase the uncertainties and costs surrounding the prosecution of our and our licensors’ or collaborators’ patent applications and the enforcement or defense of our or our licensors’ or collaborators’ issued patents. For example, assuming that other requirements for patentability are met, prior to March 2013, in the United States, the first to invent the claimed invention was entitled to the patent, while outside the United States, the first to file a patent application was entitled to the patent. After March 2013, under the Leahy-Smith America Invents Act, or the Leahy-Smith Act, enacted in September 2011, the United States transitioned to a first inventor to file system in which, assuming that other requirements for patentability are met, the first inventor to file a patent application will be entitled to the patent on an invention regardless of whether a third party was the first to invent the claimed invention. The Leahy-Smith Act also includes a number of significant changes that affect the way patent applications are prosecuted and may also affect patent litigation. These include allowing third-party submission of prior art to the USPTO during patent prosecution and additional procedures to challenge the validity of a patent by USPTO-administered post-grant proceedings, including post-grant review, inter partes review and derivation proceedings. The USPTO ~~recently~~has developed ~~new~~ regulations and procedures to govern administration of the Leahy-Smith Act, and many of the substantive changes to patent law associated with the Leahy-Smith Act, particularly the first inventor-to-file provisions. Accordingly, it is not clear what, if any, impact the Leahy-Smith Act will have on the operation of our business. However, the Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our or our licensors’ patent applications and the enforcement or defense of our or our licensors’ issued patents. Similarly, statutory or judicial changes to the patent laws of other countries may increase the uncertainties and costs surrounding the prosecution of patent applications and the enforcement or defense of issued patents. ~~All of the foregoing could harm our business, financial condition, results of operations and prospects.~~

Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated if we fail to comply with these requirements.

Periodic maintenance fees, renewal fees, annuity fees, and various other fees are required to be paid to the USPTO and foreign patent agencies in several stages over the lifetime of a patent. In certain circumstances, we rely on our licensors and collaborators to pay these fees. The USPTO and various foreign patent agencies also require compliance with a number of procedural, documentary, fee payment and other similar requirements during the patent application and prosecution process. Non-compliance events that could result in abandonment or lapse of a patent or patent application include failure to respond to official communications within prescribed time limits, non-payment of fees and failure to properly legalize and submit formal documents. While an inadvertent lapse can in some cases be cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which non-compliance can result in irrevocable abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. If we or our licensors or collaborators fail to maintain the patents and patent applications

covering our product candidates, our competitors might be able to enter the market with similar or identical products or technology, which would harm our business, financial condition, results of operations and prospects.

We may become involved in lawsuits to protect or enforce our patents or other intellectual property, which could be expensive, time-consuming and unsuccessful, and issued patents covering our technology and product candidates could be found invalid or unenforceable if challenged.

Competitors and other third parties may infringe or otherwise violate our issued patents or other intellectual property or the patents or other intellectual property of our licensors. In addition, our patents or the patents of our licensors may become involved in inventorship or priority disputes. Our pending patent applications cannot be enforced against third parties practicing the technology claimed in such applications unless and until a patent issues from such applications. To counter infringement or other unauthorized use, we may be required to file infringement claims, which can be expensive and time-consuming. Our ability to enforce patent rights also depends on our ability to detect infringement. It may be difficult to detect infringers who do not advertise the components or methods that are used in connection with their products and services. Moreover, it may be difficult or impossible to obtain evidence of infringement in a competitor’s or potential competitor’s product or service. Any claims we assert against perceived infringers could provoke these parties to assert counterclaims against us alleging that we infringe their patents or that our patents are invalid or

unenforceable. In a patent infringement proceeding, a court may decide that a patent of ours is invalid or unenforceable, in whole or in part, construe the patent’s claims narrowly or refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover the technology. An adverse result in any litigation proceeding could put one or more of our owned or licensed patents at risk of being invalidated, held unenforceable or interpreted narrowly. We may find it impractical or undesirable to enforce our intellectual property against some third parties.

If we were to initiate legal proceedings against a third party to enforce a patent directed to our product candidates, or one of our future product candidates, the defendant could counterclaim that our patent is invalid or unenforceable. In patent litigation in the United States, defendant counterclaims alleging invalidity or unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, including lack of novelty, obviousness, non-enablement or insufficient written description. Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld relevant information from the USPTO or made a misleading statement during prosecution. Third parties may also raise similar claims before the USPTO or an equivalent foreign body, even outside the context of litigation. Potential proceedings include re-examination, post-grant review, inter partes review, interference proceedings, derivation proceedings and equivalent proceedings in foreign jurisdictions (e.g., opposition proceedings). Such proceedings could result in the revocation of, cancellation of, or amendment to our patents in such a way that they no longer cover our technology or any product candidates that we may develop. The outcome following legal assertions of invalidity and unenforceability is unpredictable. With respect to the validity question, for example, we cannot be certain that there is no invalidating prior art of which we and the patent examiner were unaware during prosecution. If a defendant were to prevail on a legal assertion of invalidity or unenforceability, we would lose at least part, and perhaps all, of the patent protection on the applicable product candidates or technology covered by the patent rendered invalid or unenforceable. ~~Such a loss of patent protection would materially harm our business, financial condition, results of operations and prospects.~~

Interference proceedings provoked by third parties or brought by us or declared by the USPTO may be necessary to determine the priority of inventions with respect to our patents or patent applications. An unfavorable outcome could require us to cease using the related technology or to attempt to license rights to it from the prevailing party. Our business could be materially harmed if the prevailing party does not offer us a license on commercially reasonable terms.

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation.

Some of our competitors are larger than we are and have substantially greater resources. They are, therefore, likely to be able to sustain the costs of complex patent litigation or proceedings more effectively than we can because of their greater financial resources and more mature and developed intellectual property portfolios. Accordingly, despite our efforts, we may not be able to prevent third parties from infringing upon, misappropriating or otherwise violating our intellectual property. Even if resolved in our favor, litigation or other legal proceedings relating to intellectual property claims could result in substantial costs and diversion of management resources, which could harm our business. In addition, the uncertainties associated with litigation could compromise our ability to raise the funds necessary to continue our clinical trials, continue our internal research programs, or in-license needed technology or other product candidates. There could also be public announcements of the results of the hearing, motions, or other interim proceedings or developments. If securities analysts or investors perceive those results to be negative, it could cause the price of shares of our common stock to decline. ~~Any of the foregoing events could harm our business, financial condition, results of operation and prospects.~~

Third parties may initiate legal proceedings alleging that we are infringing, misappropriating or otherwise violating their intellectual property rights, the outcome of which would be uncertain and could negatively impact the success of our business.

Our commercial success depends upon our ability to develop, manufacture, market and sell our product candidates and use our proprietary technologies without infringing, misappropriating or otherwise violating the intellectual property and other proprietary rights of third parties. There is considerable intellectual property litigation in the pharmaceutical industry. We may become party to, or threatened with, future adversarial proceedings or litigation regarding intellectual property rights with respect to our product candidates and their manufacture and our other technology, including re-examination, interference, post-grant review, inter partes review or derivation proceedings before the USPTO or an equivalent foreign body. Numerous U.S. and foreign issued patents and pending patent applications owned by third parties exist in the fields in which we are developing our product candidates. Third parties may assert infringement claims against us based on existing patents or patents that may be granted in the future, regardless of their merit.

Even if we believe third-party intellectual property claims are without merit, there is no assurance that a court would find in our favor on questions of infringement, validity, enforceability or priority. A court of competent jurisdiction could hold that third-party patents asserted against us are valid, enforceable and infringed, which could materially and adversely affect our ability to commercialize any product candidates we may develop and any other product candidates or technologies covered by the asserted third-party patents. In order to successfully challenge the validity of ~~any such~~a U.S. patent in federal court, we would need to overcome a presumption of validity. As this burden is a high one requiring us to present clear and convincing evidence as to the invalidity of ~~any such~~a U.S. patent claim, there is no assurance that a court of competent jurisdiction would invalidate the claims of any such U.S. patent. If we are found to infringe, misappropriate or otherwise violate a third party’s intellectual property rights, and we are unsuccessful in demonstrating that ~~such~~these rights are invalid or unenforceable, we could be required to obtain a license from such a third party in order to continue developing and marketing our products and technology. However, we may not be able to obtain any required license on commercially reasonable terms or at all. Even if we were able to obtain a license, it could be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. We could be forced, including by court order, to cease commercializing the infringing technology or product. A finding of infringement could prevent us from commercializing our product candidates or force us to cease some of our business operations. In the event of a successful claim of infringement against us, we may have to pay substantial damages, including treble damages and attorneys’ fees for willful infringement, pay royalties and other fees, redesign our infringing product candidate or obtain one or more licenses from third parties, which may be impossible or require substantial time and monetary expenditure. Claims that we have misappropriated the confidential information or trade secrets of third parties could have a similar negative impact on our business. ~~Any of the foregoing events would harm our business, financial condition, results of operations and prospects.~~

We may be subject to claims by third parties asserting that we or our employees have infringed upon, misappropriated or otherwise violated their intellectual property rights, or claiming ownership of what we regard as our own intellectual property.

Many of our employees were previously employed at other biotechnology or pharmaceutical ~~companies.~~companies and our consultants and advisors may work for other biotechnology or pharmaceutical companies in addition to us. Although we try to ensure that our employees, consultants and advisors do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or these individuals have used or disclosed intellectual property, including trade secrets or other proprietary information, of any ~~such individual’s~~of these individuals’ former ~~employer.~~or concurrent employers or clients. We may also be subject to claims that patents and applications we have filed to protect inventions of our employees, consultants and advisors, even those related to one or more of our product candidates, are rightfully owned by their former or concurrent employer. Litigation may be necessary to defend against these claims.

If we fail in prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. Even if we are successful in prosecuting or defending against ~~such~~these claims, litigation could result in substantial costs, delay development of our product candidates and be a distraction to management. ~~Any of the foregoing events would harm our business, financial condition, results of operations and prospects.~~

We may be subject to claims challenging the inventorship of our patents and other intellectual property.

We or our licensors may be subject to claims that former employees, collaborators or other third parties have an interest in our owned or in-licensed patents, trade secrets, or other intellectual property as an inventor or co-inventor. For example, we or our licensors may have inventorship disputes arise from conflicting obligations of employees, consultants or others who are involved in developing our product candidates. While it is our policy to require our employees and contractors who may be involved in the development of intellectual property to execute agreements assigning ~~such~~this intellectual property to us, we may be unsuccessful in executing such an agreement with each party who in fact develops intellectual property that we regard as our own. Our and their assignment agreements may not be self-executing or may be breached, and litigation may be necessary to defend against these and other claims challenging inventorship or our or our licensors’ ownership of our owned or in-licensed patents, trade secrets or other intellectual property. If we or our licensors fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights, such as exclusive ownership of, or right to use, intellectual property that is important to our product candidates. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management and other employees. ~~Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.~~

Intellectual property litigation could cause us to spend substantial resources and distract our personnel from their normal responsibilities.

Even if resolved in our favor, litigation or other legal proceedings relating to intellectual property claims may cause us to incur significant expenses, and could distract our technical and management personnel from their normal responsibilities. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments and if securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price of our common stock. Such litigation or proceedings could substantially increase our operating losses and reduce the resources available for development activities or any future sales, marketing or distribution activities. We may not have sufficient financial or other resources to conduct such litigation or proceedings adequately. As noted above, some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their greater financial resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could compromise our ability to compete in the marketplace, including compromising our ability to raise the funds necessary to continue our clinical trials, continue our research programs, license necessary technology from third parties, or enter into development collaborations that would help us commercialize our product candidates, if approved. ~~Any of the foregoing events would harm our business, financial condition, results of operations and prospects.~~

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.

We rely on trade secrets and confidentiality agreements to protect our unpatented know-how, technology and other proprietary information (including unpatented know-how associated with Warp Drive) and to maintain our competitive position. Trade secrets and know-how can be difficult to protect. We seek to protect these trade secrets and other proprietary technology, in part, by entering into non-disclosure and confidentiality agreements with parties who have access to them, such as our employees, collaborators, CROs, contract manufacturers, consultants, advisors and other third parties. We also enter into confidentiality and invention or patent assignment agreements with our employees and consultants. We cannot guarantee that we have entered into ~~such~~these agreements with each party that may have or has had access to our trade secrets or proprietary technology and processes. Despite ~~these~~our efforts, any of these parties may breach the agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. Unauthorized parties may also attempt to copy or reverse engineer certain aspects of our products that we consider proprietary. Monitoring unauthorized uses and disclosures is difficult, and we do not know whether the steps we have taken to protect our proprietary information will be effective.

We also seek to preserve the integrity and confidentiality of our confidential proprietary information by maintaining physical security of our premises and physical and electronic security of our information technology systems, but it is possible that these security measures could be breached. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is unpredictable. In addition, some courts inside and outside the United States are less willing or unwilling to protect trade secrets. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor or other third party, we would have no right to prevent them from using that technology or information to compete with us. If any of our trade secrets were to be disclosed to, or independently developed by, a competitor or other third party, our competitive position would be materially and adversely harmed.

If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our business may be adversely affected.

Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to be infringing on other marks. We may not be able to protect our rights to these trademarks and trade names, which we need to build name recognition among potential collaborators or customers in our markets of interest. At times, competitors may adopt trade names or trademarks similar to ours, thereby impeding our ability to build brand identity and possibly leading to market confusion. In addition, there could be potential trade name or trademark infringement claims brought by owners of other trademarks or trademarks that incorporate variations of our registered or unregistered trademarks or trade names. Over the long term, if we are unable to establish name recognition based on our trademarks and trade names, then we may not be able to compete effectively and our business may be adversely affected. We may license our trademarks and trade names to third parties, such as distributors. Though these license agreements may provide guidelines for how our trademarks and trade names may be used, a breach of these agreements or misuse of our trademarks and tradenames by our licensees may jeopardize our rights in or diminish the goodwill associated with our trademarks and trade names. Our efforts to enforce or protect our proprietary rights related to trademarks, trade names, trade secrets, domain names, copyrights or other intellectual property may be ineffective and could result in substantial costs and diversion of ~~resources and could adversely affect our business, financial condition, results of operations and prospects.~~resources.

Intellectual property rights do not necessarily address all potential threats.

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations and may not adequately protect our business or permit us to maintain our competitive advantage. For example:

others may be able to make products that are similar to any product candidates we may develop or utilize similar technology but that are not covered by the claims of our patents or the patents that we license or may own in the future;

we, or our current or future licensors, might not have been the first to make the inventions covered by ~~the~~an issued patent or pending patent application that we license or may own in the future;

we, or our current or future licensors might not have been the first to file patent applications covering certain of our or their inventions;

others may independently develop similar or alternative technologies or duplicate any of our technologies without infringing our owned or licensed intellectual property rights;

it is possible that our pending owned or licensed patent applications or those that we may own or license in the future will not lead to issued patents;

issued patents that we hold rights to may be held invalid or unenforceable, including as a result of legal challenges by our competitors;

our competitors might conduct research and development activities in countries where we do not have patent rights and then use the information learned from such activities to develop competitive products for sale in our major commercial markets;

we may not develop additional proprietary technologies that are patentable;

the patents of others may harm our business; and

we may choose not to file a patent in order to maintain certain trade secrets or know-how, and a third party may subsequently file a patent covering such intellectual property.

~~Should any of these events occur, they could harm our business, financial condition, results of operations and prospects.~~

Risks related to employee matters, managing our growth and other risks related to our business

We are highly dependent on our key personnel, and if we are not successful in attracting, motivating and retaining highly qualified personnel, we may not be able to successfully implement our business strategy.

We are highly dependent on members of our executive team. The loss of the services of any of them may adversely impact the achievement of our objectives. Any of our executive officers could leave our employment at any time, as all of our employees are “at-will” employees. We currently do not have “key person” insurance on any of our employees. The loss of the services of one or more of our key personnel might impede the achievement of our research, development and commercialization objectives.

Recruiting and retaining qualified employees, consultants and advisors for our business, including scientific and technical personnel, ~~also will be~~is critical to our success. Competition for skilled personnel is intense and the turnover rate can be high. We may not be able to attract and retain personnel on acceptable terms given the competition among numerous pharmaceutical and biotechnology companies and academic institutions for skilled individuals. In addition, failure to succeed in preclinical studies, clinical trials or applications for marketing approval may make it more challenging to recruit and retain qualified personnel. The inability to recruit, or the loss of services of certain executives, key employees, consultants or advisors, may impede the progress of our research, development and commercialization ~~objectives and have a material adverse effect on our business, financial condition, results of operations and prospects.~~objectives.

We currently have no sales organization. If we are unable to establish sales capabilities on our own or through third parties, we may not be able to market and sell any products effectively, if approved, or generate product revenue.

We currently do not have a marketing or sales organization. In order to commercialize any product, if approved, in the United States and foreign jurisdictions, we must build our marketing, sales, distribution, managerial and other non-technical capabilities or make arrangements with third parties to perform these services, and we may not be successful in doing so. In advance of any of our product candidates receiving regulatory approval, we expect to establish a sales organization with technical expertise and supporting distribution capabilities to commercialize each such product candidate, which will be expensive and time-consuming. We have no prior experience in the marketing, sale and distribution of pharmaceutical products, and there are significant risks involved in building and managing a sales organization, including our ability to hire, retain, and incentivize qualified individuals, generate sufficient sales leads, provide adequate training to sales and marketing personnel, and effectively manage a geographically dispersed sales and marketing team. Any failure or delay in the development of our internal sales, marketing and distribution capabilities would adversely impact the commercialization of these products. We may choose to collaborate with third parties that have direct sales forces and established distribution systems, either to augment our own sales force and distribution systems or in lieu of our own sales force and distribution systems. If we are unable to enter into such arrangements on acceptable terms or at all, we may not be able to successfully commercialize our product candidates. If we are not successful in commercializing products, either on our own or through arrangements with one or more third parties, we may not be able to generate any future product revenue and we would incur significant additional losses.

We will need to grow the size of our organization, and we may experience difficulties in managing this growth.

As of ~~March 31,~~June 30, 2020, we had ~~100~~106 full-time employees, including 8488 employees engaged in research and development. As our development and commercialization plans and strategies develop, and as we ~~transition into operating~~operate as a public company, we expect to need additional managerial, research and development, operational, sales, marketing, financial and other personnel. Future growth would impose significant added responsibilities on members of management, including:

identifying, recruiting, integrating, maintaining and motivating additional employees;

managing our internal development efforts effectively, including the clinical and FDA review process for RMC-4630 and any other product candidate we develop, while complying with our contractual obligations to contractors and other third parties; and

improving our operational, financial and management controls, reporting systems and procedures.

Our future financial performance and our ability to advance development of and, if approved, commercialize RMC-4630 and any other product candidate we develop will depend, in part, on our ability to effectively manage any future growth, and our management may also have to divert a disproportionate amount of its attention away from day-to-day activities in order to devote a substantial amount of time to managing these growth activities.

We currently rely, and for the foreseeable future will continue to rely, in substantial part on certain independent organizations, advisors and consultants to provide certain services, including substantially all aspects of marketing approval, clinical management, and manufacturing. We cannot assure you that the services of independent organizations, advisors and consultants will continue to be available to us on a timely basis when needed, or that we can find qualified replacements. In addition, if we are unable to effectively manage our outsourced activities or if the quality or accuracy of the services provided by consultants is compromised for any reason, our clinical trials may be extended, delayed or terminated, and we may not be able to obtain marketing approval of any current or future product candidates or otherwise advance our business. We cannot assure you that we will be able to manage our existing consultants or find other competent outside contractors and consultants on economically reasonable terms, or at all.

If we are not able to effectively expand our organization by hiring new employees and expanding our groups of consultants and contractors, we may not be able to successfully implement the tasks necessary to further develop and commercialize RMC-4630 and any future product candidates we develop and, accordingly, may not achieve our research, development and commercialization goals.

We have in the past engaged and may in the future engage in strategic transactions; ~~such~~these transactions could affect our liquidity, dilute our existing stockholders, increase our expenses and present significant challenges in focus and energy to our management or prove not to be successful.

From time to time, we may consider strategic transactions, such as acquisitions of companies, asset purchases and out-licensing or in-licensing of intellectual property, products or technologies. For example, in October 2018, we acquired all of the outstanding shares of Warp Drive Bio, which became our direct wholly-owned subsidiary.

Additional potential transactions that we may consider in the future include a variety of business arrangements, including spin-offs, strategic partnerships, joint ventures, restructurings, divestitures, business combinations and investments. Any future transactions could result in potentially dilutive issuances of our equity securities, including our common stock, or the incurrence of debt, contingent liabilities, amortization expenses or acquired in-process research and development expenses, any of which could affect our financial condition, liquidity and results of operations. Future acquisitions may also require us to obtain additional financing, which may not be available on favorable terms or at all. These transactions may never be successful and may require significant time and attention of management. In addition, the integration of any business that we may acquire in the future may disrupt our existing business and may be a complex, risky and costly endeavor for which we may never realize the full benefits of the acquisition.

If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could have a material adverse effect on the success of our business.

We are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use, storage, treatment and disposal of hazardous materials and wastes. Our operations involve the use of hazardous and flammable materials, including chemicals and biological and radioactive materials. Our operations also produce hazardous waste products. We generally contract with third parties for the disposal of these materials and wastes. We cannot eliminate the risk of contamination or injury from these materials. In the event of contamination or injury resulting from our use of hazardous materials, we could be held liable for any resulting damages, and any liability could exceed our resources. We also could incur significant costs associated with civil or criminal fines and penalties.

Although we maintain workers’ compensation insurance to cover us for costs and expenses, we may incur due to injuries to our employees resulting from the use of hazardous materials, this insurance may not provide adequate coverage against potential liabilities. We do not maintain insurance for environmental liability or toxic tort claims that may be asserted against us in connection with our storage or disposal of biological, hazardous or radioactive materials.

We or the third parties upon whom we depend may be adversely affected by earthquakes, outbreak of disease, or other natural disasters and our business continuity and disaster recovery plans may not adequately protect us from a serious disaster.

Our corporate headquarters and other facilities are located in the San Francisco Bay Area, which in the past has experienced both severe earthquakes and wildfires. We do not carry earthquake insurance. Earthquakes, wildfires or other natural disasters could severely disrupt our operations, and have a material adverse effect on our business, results of operations, financial condition and prospects.

If a natural disaster, power outage, outbreak of disease, or other event occurred that prevented us from using all or a significant portion of our headquarters, that damaged critical infrastructure, such as our enterprise financial systems or manufacturing resource planning and enterprise quality systems, or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible, for us to continue our business for a substantial period of time. As an example, our operations are currently limited as a result of the COVID-19 pandemic, as described in the risk factor entitled “The COVID-19 pandemic, or other epidemic and pandemic diseases or the perception of their effects, could significantly disrupt our business.”The disaster recovery and business continuity plans we have in place currently are limited and are unlikely to prove adequate in the event of a serious disaster or similar event. We may incur substantial expenses as a result of the limited nature of our disaster recovery and business continuity plans, which, particularly when taken together with our lack of earthquake insurance, could have a material adverse effect on our business.

Furthermore, integral parties used in our preclinical activities and in our supply chain are similarly vulnerable to natural disasters, outbreak of disease, or other sudden, unforeseen and severe adverse events. If such an event were to affect our preclinical activities or our supply chain, it could have a material adverse effect on our business.

~~Epidemic and pandemic diseases, such as COVID-19, or the perception of their effects, could have a material adverse effect on our business, financial condition, results of operations or cash flows.~~

Outbreaks of epidemic, pandemic or contagious diseases, such as the recent SAR-CoV-2 virus, or, historically, the Ebola virus, Middle East Respiratory Syndrome, Severe Acute Respiratory Syndrome or the H1N1 virus, could significantly disrupt our business. Such outbreaks pose the risk that we or our employees, contractors, suppliers, and other partners may be prevented from conducting business activities for an indefinite period of time due to spread of the disease within these groups, or due to shutdowns that may be requested or mandated by federal, state and local governmental authorities. Business disruptions could include disruptions or restrictions on our ability to travel, as well as temporary closures of our facilities and the facilities of our partners, clinical trial sites, service providers, suppliers or contract manufacturers. While it is not possible at this time to estimate the overall impact that COVID-19 will have on our business, the continued rapid spread of COVID-19, both across the United States and through much of the world, and the measures taken by the governments of countries and local authorities affected could disrupt and delay our ongoing clinical trials, our preclinical activities, the manufacture or shipment of both drug substance and finished drug product for our product candidates for preclinical testing and clinical trials and adversely impact our business, financial condition or results of operations.

For example, as a result of the COVID-19 pandemic, the state of California, where our corporate offices are located, has issued orders for all residents to remain at home, except as needed for essential activities, and we have had to implement work from home policies that may continue for an indefinite period. We have taken steps to ensure the safety of our patients and employees, while working to ensure the sustainability of our business operations as this unprecedented situation continues to evolve. We continue to evaluate the impact of COVID-19 on the healthcare system and work with healthcare providers supporting our clinical studies to mitigate risk to patients while taking into account regulatory, institutional, and government guidance and policies. All of our clinical trial sites for our RMC-4630 clinical studies are currently located in the U.S., and may be affected by the COVID-19 outbreak due to prioritization of hospital resources toward the COVID-19 outbreak, travel or quarantine restrictions imposed by federal, state or local governments, and the inability to access sites for initiation and patient monitoring and enrollment. As a result, patient screening, new patient enrollment, monitoring and data collection may be affected or delayed. We are aware of several clinical sites involved in our RMC-4630 clinical studies that have temporarily stopped or delayed enrolling new patients, with exemptions if appropriate. These developments may delay our clinical trial timelines. Some of our third-party manufacturers which we use for the supply of materials for product candidates or other materials necessary to manufacture product to conduct preclinical tests and clinical trials are located in countries affected by COVID-19, and should they experience continued disruptions, such as temporary closures or suspension of services, we would likely experience delays in advancing clinical trials. Currently, we expect no material impact on the clinical supply of RMC-4630. Furthermore, the spread of the virus may affect the operations of key governmental agencies, such as the FDA, which may delay the development of our product candidates. The spread of an infectious disease, including COVID-19, may also result in the inability of our suppliers to deliver components or raw materials on a timely basis or at all. Such events may result in a period of business disruption, and in reduced operations, or doctors and medical providers may be unwilling to participate in our clinical trials, any of which could materially affect our business, financial condition and results of operations.

Our internal computer systems, or those used by our CROs or other contractors or consultants, may fail or suffer security breaches.

Despite the implementation of security measures, our internal computer systems and those of our future CROs and other contractors and consultants are vulnerable to damage from computer viruses and unauthorized access. While we have not to our knowledge experienced any such material system failure or security breach to date, if such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our development programs and our business operations. For example, the loss of clinical trial data from completed or future clinical trials could result in delays in our marketing approval efforts and significantly increase our costs to recover or reproduce the data. Likewise, we rely on third parties for the manufacture of our product candidates and to conduct clinical trials, and similar events relating to their computer systems could also have a material adverse effect on our business. To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the further development and commercialization of our future product candidates could be delayed.

Our employees, independent contractors, vendors, principal investigators, CROs and consultants may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements and insider trading.

We are exposed to the risk that our employees, independent contractors, vendors, principal investigators, CROs and consultants may engage in fraudulent conduct or other illegal activity. Misconduct by these parties could include intentional, reckless ~~and/~~or negligent conduct or disclosure of unauthorized activities to us that violate the regulations of the FDA ~~and~~or comparable foreign regulatory authorities, including those laws requiring the reporting of true, complete and accurate information to such authorities; healthcare fraud and abuse laws and regulations in the United States and abroad; or laws that require the reporting of financial information or data accurately. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Activities subject to these laws also involve the improper use of information obtained in the course of clinical trials or creating fraudulent data in our preclinical studies or clinical trials, which could result in regulatory sanctions and cause serious harm to our reputation. It is not always possible to identify and deter misconduct by employees and other third parties, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. Additionally, we are subject to the risk that a person could allege ~~such~~ fraud or other misconduct, even if none occurred. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of civil, criminal and administrative penalties, damages, monetary fines, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, reputational harm, ~~diminished profits and future earnings,~~ and curtailment of our ~~operations, any of which could adversely affect our ability to operate our business and our results of~~ operations.

Risks Related to Our Common Stock

The price of our common stock ~~may be~~is volatile and ~~fluctuate~~fluctuates substantially, which could result in substantial losses for investors.

Our stock price is ~~likely to be~~highly volatile. The stock market in general, and the market for biopharmaceutical companies in particular, have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. The COVID-19 pandemic, actions taken by governments in response to this pandemic and the related economic impacts, have exacerbated this volatility, particularly as it relates to stocks of biopharmaceutical companies like ours.

The market price for our common stock may be influenced by many factors, including:

~~the success of competitive products or technologies;~~our research and development efforts and our ability to discover and develop product candidates;

results of our clinical trials and preclinical studies or those of our competitors;

the success of competitive products or technologies;

regulatory or legal developments in the United States and other countries;

developments or disputes concerning patent applications, issued patents or other proprietary rights;

the recruitment or departure of key personnel;

the level of expenses related to our product candidates or clinical development programs;

the results of our efforts to discover, develop, acquire or in-license product candidates or companion diagnostics;

actual or anticipated changes in estimates as to financial results, development timelines or recommendations by securities analysts;

variations in our financial results or those of companies that are perceived to be similar to us;

changes in the structure of healthcare payment systems;

~~market conditions in the pharmaceutical and biotechnology sectors; and~~

•

market conditions in the pharmaceutical and biotechnology sectors; and

An active ~~trading~~and liquid market for our common stock may not be sustained.

Our common stock is currently listed on the Nasdaq Global Select Market under the symbol “RVMD”. The price for our common stock may vary and an active orand liquid market in our common stock may not be sustained. The lack of an active market may impair the value of your shares, your ability to sell your shares at the time you wish to sell them and the prices that you may obtain for your shares. An inactive market may also impair our ability to raise capital by selling our common stock and our ability to acquire other companies, products or technologies by using our common stock as consideration.

We do not intend to pay dividends on our common stock so any returns will be limited to the value of our stock.

We do not currently intend to pay any cash dividends on our common stock for the foreseeable future. We currently intend to invest our future earnings, if any, to fund our growth. Therefore, ~~you~~stockholders are not likely to receive any dividends on ~~your~~their common stock for the foreseeable future. Since we do not intend to pay dividends, ~~your~~stockholders’ ability to receive a return on ~~your~~their investment will depend on any future appreciation in the market value of our common stock. There is no guarantee that our common stock will appreciate or even maintain the price at which our holders have purchased it.

We are an emerging growth company, and we cannot be certain if the reduced reporting requirements applicable to emerging growth companies will make our common stock less attractive to investors.

We are an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. For as long as we continue to be an emerging growth company, we may take advantage of exemptions from various reporting requirements, that are applicable to other public companies that are not emerging growth companies, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation and exemptions from the requirements of holding nonbinding advisory votes on executive compensation and stockholder approval of any golden parachute payments not previously approved. We ~~could be an emerging growth company for up to five years following the year of our IPO, although circumstances could cause us to lose that status earlier. We~~ will remain an emerging growth company until the earlier of (1) December 31, 2025, (2) the last day of the fiscal year ~~(a) following the fifth anniversary of the completion of our IPO, (b)~~ in which we have total annual gross revenue of at least $1.07 billion, ~~or (c)~~(3) the last day of the fiscal year in which we are deemed to be a large accelerated filer, which requires the market value of our common stock that is held by non-affiliates to exceed $700.0 million as of the prior June 30th, ~~and (2)~~or (4) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period. We cannot predict if investors will find our common stock less attractive because we may rely on these exemptions. If some investors find our common stock less attractive as a result, our stock price may be depressed, there may be a less active trading market for our common stock and our stock price may be more volatile.

Under the JOBS Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have elected to use the extended transition period for any other new or revised accounting standards during the period in which we remain an emerging growth company; however, we may adopt certain new or revised accounting standards early. As a result, changes in rules of U.S. generally accepted accounting principles or their interpretation, the adoption of new guidance or the application of existing guidance to changes in our business could significantly affect our financial position and results of operations.

Our executive officers, directors and their affiliates have significant influence over our company, which will limit your ability to influence corporate matters and could delay or prevent a change in corporate control.

As of ~~March 31,~~June 30, 2020, our executive officers, directors and their affiliates beneficially own, in the aggregate, ~~approximately 43%~~over 40% of our outstanding common stock. As a result, these stockholders, if they act together, will be able to influence our management and affairs and the outcome of matters submitted to our stockholders for approval, including the election of directors and any sale, merger, consolidation or sale of all or substantially all of our assets. In addition, this concentration of ownership might adversely affect the market price of our common stock by:

See Part III, Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters” under the caption “Security Ownership of Certain Beneficial Owners and Management” in our 2019 Form 10-K for more information regarding the ownership of our outstanding common stock by our executive officers, directors and their affiliates.

We incur significantly increased costs as a result of operating as a public company, and our management ~~is required to devote~~devotes substantial time to new compliance initiatives. We may fail to comply with the rules that apply to public companies, including Section 404 of the Sarbanes-Oxley Act of 2002, which could result in sanctions or other penalties that would harm our business.

~~As a public company, we~~We incur significant legal, accounting and other expenses ~~that we did not incur~~ as a ~~private company. We are subject to the~~public company, including costs resulting from public company reporting ~~requirements of~~obligations under the Securities Exchange Act of 1934, as amended, or the Exchange Act, ~~which requires, among other things, that we file with the SEC annual, quarterly~~ and current reports with respect to our business and financial condition. In addition, the Sarbanes-Oxley Act, as well as rules subsequently adopted by the SEC and Nasdaq to implement provisions of the Sarbanes-Oxley Act, impose significant requirements on public companies, including requiring establishment and maintenance of effective disclosure and financial controls and changes inregulations regarding corporate governance practices. ~~Further, in July 2010,~~The listing requirements of the ~~Dodd-Frank Wall Street Reform~~Nasdaq Global Select Market and ~~Consumer Protection Act,~~the rules of the Securities and Exchange Commission, or ~~the Dodd-Frank Act, was enacted. There are significant~~SEC, require that we satisfy certain corporate governance requirements relating to director independence, filing annual and ~~executive compensation-related provisions in~~interim reports, stockholder meetings, approvals and voting, soliciting proxies, conflicts of interest and a code of conduct. Our management and other personnel devote a substantial amount of time to ensure that we comply with all of these requirements. Moreover, the ~~Dodd-Frank Act that require the SEC to adopt additional~~reporting requirements, rules and regulations inwill increase our legal and financial compliance costs and make some activities more time-consuming and costly. Any changes we make to comply with these areas such as “say on pay” and proxy access. Recent legislation permits emerging growth companies to implement many of these requirements over a longer period and up to five years from the pricing of their IPO. We intend to take advantage of this legislation, but cannot guarantee that we willobligations may not be ~~required~~sufficient to ~~implement these~~allow us to satisfy our obligations as a public company on a timely basis, or at all. These reporting requirements, ~~sooner than budgeted~~rules and regulations, coupled with the increase in potential litigation exposure associated with being a public company, could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors or ~~planned~~board committees or to serve as executive officers, or to obtain certain types of insurance, including directors’ and ~~thereby incur unexpected expenses.~~officers’ insurance, on acceptable terms. Stockholder activism, the current political environment and the current high level of government intervention and regulatory reform may lead to substantial new regulations and disclosure obligations, which may lead to additional compliance costs and impact the manner in which we operate our business in ways we cannot currently anticipate.

~~We expect~~As a public company, we are subject to Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, and the related rules of the SEC, which generally require our management and ~~regulations~~independent registered public accounting firm to report on the effectiveness of our internal control over financial reporting. Beginning with the second annual report that we will be required to file with the SEC, Section 404 requires an annual management assessment of the effectiveness of our internal control over financial reporting. However, for so long as we remain an emerging growth company as defined in the JOBS Act, we intend to take advantage of certain exemptions from various reporting requirements that are applicable to public companies that are not emerging growth companies, including, but not limited to, ~~substantially increase~~not being required to comply with the auditor attestation requirements of Section 404. Once we are no longer an emerging growth company or, if prior to such date, we opt to no longer take advantage of the applicable exemption, we will be required to include an opinion from our ~~legal and financial compliance costs and to make some activities more time-consuming and costly. If these requirements divert~~independent registered public accounting firm on the ~~attention~~effectiveness of our ~~management~~internal control over financial reporting.

During the course of our review and testing, we may identify deficiencies and be unable to remediate them before we must provide the required reports. Furthermore, if we have a material ~~adverse effect~~weakness in our internal controls over financial reporting, we may not detect errors on a timely basis and our ~~business,~~ financial ~~condition,~~statements may be materially misstated. We or our independent registered public accounting firm may not be able to conclude on an ongoing basis that we have effective internal control over financial reporting, which could harm our operating results, cause investors to lose confidence in our reported financial information and cause the trading price of our stock to fall. In addition, as a public company we are required to file accurate and timely quarterly and annual reports with the SEC under the Exchange Act. In order to report our results of operations and ~~prospects.

The impact of these requirements could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees or as executive officers.business.

Sales of a substantial number of shares of our common stock in the public market could cause our stock price to fall.

If our existing stockholders sell, or indicate an intention to sell, substantial amounts of our common stock in the public market, the market price of our common stock could decline.

If our existing stockholders sell, or indicate an intention to sell, substantial amounts of our common stock in the public market after the lock-up and other legal restrictions on resale related to our most recent public offering lapse, the trading price of our common stock could decline. As of ~~March 31,~~June 30, 2020, we had outstanding 59,003,644 shares of common stock. The resale of ~~42,895,971~~approximately 42.9million shares ~~or 73%~~ of our outstanding shares of common stock is currently prohibited or otherwise restricted as a result of securities law provisions, market standoff agreements entered into by certain of our stockholders with us or lock-up agreements entered into by our stockholders with the underwriters in connection with our IPO. The lock-up agreements pertaining to our IPO with the underwriters or market stand-off provisions in agreements with us will expire ~~180 days~~ after ~~February 12,~~August 10, 2020. J.P. Morgan Securities LLC may, in its sole discretion, permit us or our stockholders who are subject to these lock-up agreements to sell shares prior to the expiration of the lock-up agreements. After the lock-up agreements or market stand-off provisions with the underwriters of our IPO or market stand-off provisions in agreements with us expire, the shares of common stock will be eligible for sale in the public ~~market. Approximately 55% of these additional shares are held by directors, executive officers and other affiliates and will be~~market subject to certain limitations of Rule 144 under the Securities Act of 1933, as amended, or the Securities Act.

The lock-up agreements entered into in connection with our public offering in July 2020 will expire after October 6, 2020. After the lock-up agreements expire, up to approximately 23.5 million additional shares of common stock held by directors, executive officers and other affiliates will be eligible for sale in the public market, subject to Rule 144 under the Securities Act of 1933, as amended, or the Securities Act. J.P. Morgan Securities LLC may, however, in its sole discretion, permit our officers, directors and other stockholders who are subject to these lock-up agreements to sell shares prior to the expiration of the lock-up agreements.

As of ~~March 31,~~June 30, 2020, ~~11,207,358~~11.2 million shares of common stock that are either subject to outstanding options or reserved for future issuance under our equity incentive plans will become eligible for sale in the public market to the extent permitted by the provisions of various vesting schedules, the lock-up agreements, market stand-off provisions in agreements with us and Rule 144 and Rule 701 under the Securities Act. If these additional shares of common stock are sold, or if it is perceived that they will be sold, in the public market, the market price of our common stock could decline.

In addition, holders of approximately 39.6 million shares of our common stock are entitled to rights with respect to the registration of their shares under the Securities Act, subject to the lock-up agreements described above. Registration of these shares under the Securities Act would result in the shares becoming freely tradable without restriction under the Securities Act, except for shares purchased by affiliates. Any sales of securities by these stockholders could have a material adverse effect on the market price of our common stock.

Our ability to utilize our net operating loss carryforwards and certain other tax attributes has been limited by “ownership changes” and may be further limited.

Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, or the Code, and corresponding provisions of state law, if a corporation undergoes an “ownership change” (generally defined as a greater than 50 percentage point change (by value) in its equity ownership over a rolling three-year period), the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes to offset its post-change income may be limited. We have experienced ownership changes in the past, ~~experienced,~~ and we may experience ownership changes in the future ~~experience ownership changes~~ as a result of our ~~IPO~~public offerings or other changes in our stock ownership (some of which are not in our control). Use of our federal and state net operating loss carryforwards have been limited and could be further limited if we experience additional ownership ~~changes, which could have an adverse effect on our future results of operations.~~changes.

If we sell shares of our common stock in future financings, stockholders may experience immediate dilution and, as a result, our stock price may decline.

We may from time to time issue additional shares of common stock at a discount from the current trading price of our common stock. As a result, our stockholders would experience immediate dilution upon the purchase of any shares of our common stock sold at such discount. In addition, as opportunities present themselves, we may enter into financing or similar arrangements in the future, including the issuance of debt securities, preferred stock or common stock. If we issue common stock or securities convertible into common stock, our common stockholders would experience additional dilution and, as a result, our stock price may decline.

If securities analysts do not continue to publish research or reports about our business or if they publish negative evaluations of our stock, the price of our stock could decline.

The trading market for our common stock relies, in part, on the research and reports that industry or financial analysts publish about us or our business. If few analysts ~~commence coverage of~~publish research or reports about us, the trading price of our stock would likely decrease. If one or more of the analysts covering our business downgrade their evaluations of our stock, the price of our stock could decline. If one or more of these analysts cease to cover our stock, we could lose visibility in the market for our stock, which, in turn, could cause our stock price to decline.

If we fail to maintain proper and effective internal control over financial reporting, our ability to produce accurate and timely financial statements could be impaired, investors may lose confidence in our financial reporting and the trading price of our common stock may decline.

Pursuant to Section 404 of Sarbanes-Oxley, our management is required to report upon the effectiveness of our internal control over financial reporting beginning with the annual report for our fiscal year ending December 31, ~~2021.~~2020. When we lose our status as an “emerging growth company,” our independent registered public accounting firm will be required to attest to the effectiveness of our internal control over financial reporting. The rules governing the standards that must be met for management to assess our internal control over financial reporting are complex and require significant documentation, testing and possible remediation.

To comply with the requirements of being a reporting company under the Exchange Act, we will need to implement additional financial and management controls, reporting systems and procedures and hire additional accounting and finance staff.

~~We cannot assure you that there will not~~There may be material weaknesses in our internal control over financial reporting in the future. Any failure to implement and maintain internal control over financial reporting could severely inhibit our ability to accurately report our financial condition, results of operations or cash flows. If we are unable to conclude that our internal control over financial reporting is effective, or if our independent registered public accounting firm determines we have a material weakness in our internal control over financial reporting, investors may lose confidence in the accuracy and completeness of our financial reports, the market price of our common stock could decline, and we could be subject to sanctions or investigations by Nasdaq, the SEC or other regulatory authorities. Failure to remedy any material weakness in our internal control over financial reporting, or to implement or maintain other effective control systems required of public companies, could also restrict our future access to the capital markets.

Provisions in our charter documents and under Delaware law could discourage a takeover that stockholders may consider favorable and may lead to entrenchment of management.

Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that could delay or prevent changes in control or changes in our management without the consent of our board of directors. These provisions include the following:

We are also subject to the anti-takeover provisions contained in Section 203 of the Delaware General Corporation Law. Under Section 203, a corporation may not, in general, engage in a business combination with any holder of 15% or more of its capital stock unless the holder has held the stock for three years or, among other exceptions, the board of directors has approved the transaction.

Claims for indemnification by our directors and officers may reduce our available funds to satisfy successful third-party claims against us and may reduce the amount of money available to us.

Our amended and restated certificate of incorporation and amended and restated bylaws provide that we will indemnify our directors and officers, in each case to the fullest extent permitted by Delaware law.

In addition, as permitted by Section 145 of the Delaware General Corporation Law, our amended and restated bylaws ~~which became effective immediately prior to the completion of our IPO~~ and our indemnification agreements that we have entered into with our directors and officers provide that:

Our amended and restated certificate of incorporation and amended and restated bylaws provide for an exclusive forum in the Court of Chancery of the State of Delaware for certain disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.

Our amended and restated certificate of incorporation and amended and restated bylaws provide that the Court of Chancery of the State of Delaware is the exclusive forum for any state law derivative action or proceeding brought on our behalf, any action asserting a breach of fiduciary duty, any action asserting a claim against us arising pursuant to the Delaware General Corporation Law, any action to interpret, apply, enforce, or determine the validity of our amended and restated certificate of incorporation or our amended and restated bylaws, or any action asserting a claim against us that is governed by the internal affairs doctrine; provided that, the exclusive forum provision will not apply to suits brought to enforce any liability or duty created by the Securities Act or the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction; and provided further that, if and only if the Court of Chancery of the State of Delaware dismisses any such action for lack of subject matter jurisdiction, such action may be brought in another state or federal court sitting in the State of Delaware. Nothing in our amended and restated certificate of incorporation or amended and restated bylaws preclude stockholders that assert claims under the Securities Act or the Exchange Act from bringing such claims in state or federal court, subject to applicable law.

We believe these provisions may benefit us by providing increased consistency in the application of Delaware law and federal securities laws by chancellors and judges, as applicable, particularly experienced in resolving corporate disputes, efficient administration of cases on a more expedited schedule relative to other forums and protection against the burdens of multi-forum litigation. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or any of our directors, officers, other employees or stockholders, which may discourage lawsuits with respect to such claims, although our stockholders will not be deemed to have waived our compliance with federal securities laws and the rules and regulations thereunder. If a court were to find the choice of forum provision ~~that is included~~ in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could adversely affect our business, financial condition, results of operations and prospects.

~~Comprehensive tax reform legislation could adversely affect our business and financial condition.~~

On December 22, 2017, the U.S. government enacted the TCJA, which significantly reforms the Code. The TCJA, among other things, contains significant changes to corporate taxation, including reduction of the U.S. federal income corporate tax rate from a top marginal rate of 35% to a flat rate of 21%, effective January 1, 2018; limitation of the tax deduction for interest expense; limitation of the deduction for net operating losses and elimination of net operating loss carrybacks, in each case, for losses arising in taxable years beginning after December 31, 2017 (though any such tax losses may be carried forward indefinitely); and modifying or repealing many business deductions and credits, including reducing the business tax credit for certain clinical testing expenses incurred in the testing of certain drugs for rare diseases or conditions generally referred to as “orphan drugs.” We continue to examine the impact this tax reform legislation may have on our business. The U.S. Department of Treasury has broad authority to issue regulations and interpretative guidance that may significantly impact how we will apply the law and impact our results of operations in the period issued. As such, the application of accounting guidance for such items is currently uncertain. While we have completed our accounting for the effects of the TCJA, additional regulatory guidance may still be issued by the applicable taxing authorities which could materially affect our tax obligations and effective tax rate.

OnIn February ~~12,~~ 2020, our registration statement on Form S-1 (File No. 333-235968) relating to our IPO of common stock became effective. The IPO closed on February 18, 2020 at which time we issued 16,100,000 shares of common stock (including the exercise in full by the underwriters of their option to purchase an additional 2,100,000 shares of common stock) at a public offering price of $17.00 per share. We received net proceeds from the IPO of approximately $250.7 million, after deducting the underwriting discounts and commissions of $19.2 million and expenses of $3.8 million. None of the expenses associated with the IPO were paid to directors, officers, persons owning 10% or more of any class of equity securities, or to our affiliates. J.P. Morgan Securities LLC, Cowen and Company, LLC, SVB Leerink LLC and Guggenheim Securities, LLC acted as joint book-running managers for the offering.

In July 2020, our registration statement on Form S-1 (File No. 333-239700) related to our secondary public offering became effective. The secondary public offering closed on July 13, 2020 at which time we issued 6,900,000 shares of common stock (including the exercise in full by the underwriters of their option to purchase an additional 900,000 shares of common stock) at a public offering at a price of $26.00 per share. We received net proceeds of $167.9 million, after deducting underwriting discounts and commissions of $10.8 million and offering expenses of $0.7 million. None of the expenses associated with the public offering were paid to directors, officers, persons owning 10% or more of any class of equity securities, or to our affiliates. J.P. Morgan Securities LLC, Cowen and Company, LLC, SVB Leerink LLC and Guggenheim Securities, LLC acted as joint book-running managers for the offering.

There has been no material change in the planned use of proceeds from ~~the IPO from that~~our public offerings as described in ~~the prospectus~~our final prospectuses filed with the SEC on February 13, 2020 and July 6, 2020, respectively, pursuant to Rule 424(b)(4) ~~under~~. We invested the ~~Securities Act on February 13, 2020.~~funds received in interest-bearing, investment-grade securities consisting of government securities, corporate bonds, and commercial paper.

~~None.~~The following table summarizes repurchases of our common stock during the three-month period ended June 30, 2020:

All of the shares repurchased, as reflected in the table above, were repurchases of unvested shares of our common stock that had been issued upon early exercise of stock options. Upon termination of employment of a person holding unvested shares, we are entitled to repurchase the unvested shares.
