FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form
10-Q
contains forward-looking statements that involve substantial risks and uncertainties. All statements, other than statements of historical facts, contained in this Quarterly Report on Form
10-Q,
including statements regarding our strategy, future operations, future financial position, projected costs, prospects, plans and objectives of management, are forward-looking statements. In some cases, you can identify forward-looking statements by terms such asincluding, but not limited to, “may,” “likely,” “will,” “should,” “would,” “design,” “expect,” “seek,” “plan,” “anticipate,” “could,” “intend,” “target,” “project,” “believe,” “estimate,” “predict,” “potential” or “continue” or the negative of these terms or other similar expressions.

These forward-looking statements include, but are not limited to, statements about:

our proposed combination with F-star Therapeutics Limited (“F-star”);

our ongoing and planned preclinical studies and clinical trials;

preclinical study data and clinical trial data and the timing of results of our ongoing clinical studies and/or trials; and

our ongoing and planned preclinical studies and clinical trials;

our estimates regarding prospects, strategies, expenses, operating capital requirements, results of operations and needs for additional financing.

We

preclinical study data and clinical trial data and the timing of results of our ongoing clinical studies and/or trials;
our plans to seek and enter into clinical trial collaborations and other broader collaborations;
the direct and indirect impact of the
COVID-19
pandemic on our business operations and financial condition, including manufacturing, research and development costs, clinical trials, regulatory processes and employee expenses; and
our estimates regarding prospects, strategies, expenses, operating capital requirements, results of operations and needs for additional financing.
Although we believe that we have a reasonable basis for each forward-looking statement contained in this Quarterly Report, we may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our forward-looking statements. Actual results or events could differ materially from the plans, intentions and expectations disclosed in the forward-looking statements we make. Factors that could cause actual results or events to differ materially from the forward-looking statements that we make include, but are not limited to, the following:

Our proposed business combination with F-star is subject to a number of closing conditions, including a condition requiring our stockholders to approve the issuance of Spring Bank common stock at the closing of the proposed combination, and it may never occur. Even if this proposed combination is completed, the number of shares of our common stock to be issued to the holders of share capital of F-star will be based on an exchange ratio formula that is subject to adjustment based on, among other things, the amount of our net cash upon the closing of the business combination and the amount of proceeds from a concurrent private placement conducted by F-star. This exchange ratio is adjustable not based on the value of our shares of common stock or on the value of the share capital of F-star. The proposed combination also contemplates that our stockholders as of a date prior to the closing of the business combination will receive two separate contingent value rights related to our STING programs. There can be no assurance that our stockholders will ever receive payment pursuant to these rights, and these rights may expire valueless.

We are very early in our development efforts and our product candidates may not be successful in later stage clinical trials. Results obtained in our preclinical studies and clinical trials to date are not necessarily indicative of results to be obtained in future clinical trials. As a result, our product candidates may never be approved as marketable therapeutics.

We rely, and expect to continue to rely, on third parties to conduct our clinical trials and to manufacture our product candidates for preclinical and clinical testing. These third parties may not perform satisfactorily, which could delay our product development activities.

If we are unable to adequately protect our proprietary technology or obtain and maintain issued patents which are sufficient to protect our product candidates, others could compete against us more directly, which would have a material adverse impact on our business, results of operations, financial condition and prospects.

Business interruptions resulting from the coronavirus disease 2019 (COVID-19) outbreak or similar public health crises could cause a disruption of the development of our product candidates and adversely impact our business.

We are very early in our development efforts and our product candidates may not be successful in later stage clinical trials. Results obtained in our preclinical studies and clinical trials to date are not necessarily indicative of results to be obtained in future clinical trials. As a result, our product candidates may never be approved as marketable therapeutics.
We will need additional funding to complete the development of our product candidates and before we can expect to become profitable from the sales of our products, if approved. If we are unable to raise capital when needed, we could be forced to delay, reduce or eliminate our product development programs or commercialization efforts.
We rely, and expect to continue to rely, on third parties to conduct our clinical trials and to manufacture our product candidates for preclinical and clinical testing. These third parties may not perform satisfactorily, which could delay our product development activities.
If we are unable to adequately protect our proprietary technology or obtain and maintain issued patents which are sufficient to protect our product candidates, others could compete against us more directly, which would have a material adverse impact on our business, results of operations, financial condition and prospects.
We may not be able to retain key executives or to attract, retain and motivate key personnel. If we are unable to retain such key personnel, it could have a material adverse impact on our business and prospects.
Business interruptions resulting from the coronavirus disease
(“COVID-19”)
outbreak or similar public health crises could cause a disruption of the development of our product candidates and adversely impact our business.
You should read this Quarterly Report on Form
10-Q
and the documents that we have filed as exhibits to this Quarterly Report on Form
10-Q
completely and with the understanding that our actual future results may be materially different from what we expect. You should also read carefully the risk factors described in “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2019 and our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020, as filed with the Securities and Exchange Commission (the “SEC”) on February 14, 2020 and May 7, 2020, respectively,March 30, 2021, to better understand the risks and uncertainties inherent in our business and underlying any forward-looking statements. You are advised, however, to consult any further disclosures we make on related subjects in our subsequent Quarterly Reports on
Form 10-Q,
Current Reports on Form
8-K,
press releases, and our website. Any forward-looking statements that we make in this Quarterly Report on
Form 10-Q
speak only as of the date of this Quarterly Report on Form
10-Q,
and we undertake no obligation to update such statements to reflect events or circumstances after the date of this Quarterly Report on
Form 10-Q
or to reflect the occurrence of unanticipated events.

Spring Bank Pharmaceuticals,

Therapeutics Inc.

Notes to Consolidated Financial Statements

1. NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Business

Spring Bank Pharmaceuticals, and Summary of Significant Accounting Policies

Nature of Business
F-star
Therapeutics, Inc. (the
(collectively with its subsidiaries,
“F-star”
or the “Company”) is a clinical-stage biopharmaceutical company engageddedicated to developing next generation immunotherapies to transform the lives of patients with cancer.
F-star’s
goal is to offer patients better and more durable benefits than currently available immuno-oncology treatments by developing medicines that seek to block tumor immune evasion. Through its proprietary tetravalent, bispecific natural antibody (mAb²
) format,
F-star’s
mission is to generate highly differentiated medicines with monoclonal antibody-like manufacturability, good safety and tolerability. With four distinct binding sites in a natural human antibody format,
F-star
believes its proprietary technology will overcome many of the discoverychallenges facing current immuno-oncology therapies, due to the strong pharmacology enabled by tetravalent bispecific binding.
F-star’s
most advanced product candidate, FS118, is currently being evaluated in a
proof-of-concept
Phase 2 trial in
PD-1/PD-L1
a
c
quired resistance head and developmentneck cancer patients. FS118 is a tetravalent mAb2 bispecific antibody targeting two receptors,
PD-L1
and
LAG-3,
both of novel therapeuticswhich are established pivotal targets in immuno- oncology. F-star’s second product candidate, FS120, aims to improve checkpoint inhibitor and chemotherapy outcomes and is a mAb2 bispecific antibody that is designed to bind to and stimulate OX40 and CD137, two proteins found on the surface of T cells that both function to enhance T cell activity. F-star’s third product candidate, FS222, aims to improve outcomes in low PD-L1 expressing tumors and is a mAb2 bispecific antibody that is designed to target both the costimulatory CD137 and the inhibitory PD-L1 receptors, which are co-expressed in a number of tumor types. SB 11285 which F-star acquired pursuant to a business combination with Spring Bank Pharmaceuticals, Inc. (“Spring Bank”), is a next generation cyclic dinucleotide STimulator of INterferon Gene (“STING”) agonist designed to improve checkpoint inhibition outcomes as an immunotherapeutic compound for the treatment of selected cancers.
Share Exchange Agreement
On November 20, 2020,
F-star
Therapeutics, Inc., formerly known as Spring Bank Pharmaceuticals, Inc., completed a rangebusiness combination (the “Transaction”) with
F-star
Therapeutics Limited
(“F-star
Ltd”) in accordance with the terms of cancers and inflammatory diseases using its proprietary small molecule nucleotide platform. The Company designs its compounds to selectively target and modulate the activity of specific proteins implicated in various disease states. The Company’s internally-developed programs are primarily designed to stimulate and/or dampen immune responses. The Company is devoting its resources to advancing multiple programs in its STING (STimulator of INterferon Genes) product portfolio.

Until January 2020, the Company was also developing inarigivir, an orally-administered investigational selective immunomodulator, as a potential treatment for chronic hepatitis B virus, or HBV. Inarigivir was being evaluated in multiple clinical trials, including the Company’s Phase 2b CATALYST trials, designed to evaluate both treatment-naïve and virally-suppressed non-cirrhotic patients with HBV under multiple dosing regimens. On January 29, 2020, the Company announced that it terminated all clinical development of inarigivir for the treatment of HBV due to the occurrence of unexpected serious adverse events, including one patient death, in the Company’s Phase 2b CATALYST trial.

OnShare Exchange Agreement, dated July 29, 2020 the Company and F-star Therapeutics Limited (“F-star”) entered into a Share Exchange Agreement (the “Exchange Agreement”), by and among the Company,

F-star
Ltd and certain holders of capital stock and convertible notes of
F-star
Ltd (each a “Seller”, and collectively with holders of
F-star
Ltd securities who subsequently became parties to the Exchange Agreement, the “Sellers”). Pursuant to the Exchange Agreement, each ordinary share of
F-star
Ltd outstanding immediately prior to the closing of the Transaction (the “Closing”) was exchanged by the Sellers that owned such
F-star
Ltd shares for a number of duly authorized, validly issued, fully paid and
non-assessable
shares of Company common stock pursuant to which, subject to the satisfaction or waiver of the conditionsexchange ratio formula set forth in the Exchange Agreement (the “Exchange Ratio”), rounded to the nearest whole share of Company common stock (after aggregating all fractional shares of Company common stock issuable to such Seller). Also, on November 20, 2020, in connection with, and prior to completion of, the Transaction, Spring Bank effected a
1-for-4
reverse stock split of its common stock (the “Reverse Stock Split”) and, following the completion of the Transaction, changed its name to
F-star
Therapeutics, Inc. Following the completion of the Transaction, the business of the Company became the business conducted by
F-star,
which is a clinical-stage immuno-oncology company focused on cancer treatment through its proprietary tetravalent bispecific antibody programs. Unless otherwise noted, all references to share amounts in this report reflect the Reverse Stock Split.
Under the terms of the Exchange Agreement, at the Closing, Spring Bank issued an aggregate of 4,620,618 shares of its common stock to
F-star
Ltd stockholders, based on an Exchange Ratio of 0.1125 shares of Spring Bank common stock for each
F-star
Ltd ordinary share, stock option and restricted stock unit (“RSU”) outstanding immediately prior to the Closing. The Exchange Ratio was determined through arms-length negotiations between Spring Bank and
F-star
Ltd pursuant to a formula set forth in the Exchange Agreement.
7

Pursuant to the Exchange Agreement, immediately prior to the Closing, certain investors in
F-star
Ltd purchased $15.0 million of
F-star
Ltd ordinary shares (the
“Pre-Closing
Financing”). These ordinary shares of
F-star
Ltd were then exchanged at the Closing for shares of the Company’s common stock in the Transaction at the same Exchange Ratio.
Pursuant to the Exchange Agreement, all outstanding options to purchase Spring Bank common stock were accelerated immediately prior to the Closing, and each outstanding option with an exercise price greater than the closing price of Spring Bank common stock on the date of the Closing (the “Closing Date”) was exercised in full, and all other outstanding options to purchase Company common stock were cancelled effective as of the Closing Date.
Immediately following the Reverse Stock Split and the Closing, there were approximately 4,449,559 shares of Spring Bank common stock outstanding. Following the Closing, the
F-star
Ltd stockholders beneficially owned approximately 53.7% of the combined Company’s common stock and the existing stockholders of Spring Bank beneficially owned approximately 46.3% of the Company’s common stock outstanding. Concurrently with the execution of the Exchange Agreement, certain officers and directors of Spring Bank and
F-star
Ltd and certain stockholders of
F-star
Ltd entered into
lock-up
agreements, pursuant to which they agreed to certain restrictions on transfers of any shares of the Company’s common stock for the
180-day
period following the Closing, other than the shares of the Company’s common stock received in exchange for ordinary shares of
F-star
Ltd subscribed for in the
Pre-Closing
Financing and pursuant to certain other limited exceptions.
In addition, at the Closing, Spring Bank,
F-star
Ltd, a representative of Spring Bank stockholders prior to the Closing, and Computershare Trust Company N.A., as the Rights Agent, entered into a STING Agonist Contingent Value Rights Agreement (the “STING Agonist CVR Agreement”). Pursuant to the Exchange Agreement and the STING Agonist CVR Agreement, each
pre-Reverse
Stock Split share of Company common stock held by stockholders as of the record date on November 19, 2020, immediately prior to the Closing, received a dividend of one contingent value right (“CVR”)(“STING Agonist CVR”), payable on a
pre-Reverse
Stock Split basis, entitling such holders to receive, in connection with certain transactions involving the proprietary STING agonist compound designated as SB 11285 occurring on or prior to the STING Agonist CVR Expiration Date (as defined below) that resulted in aggregate Net Proceeds (as defined in the STING Agonist CVR Agreement) at least equal to the Target Payment Amount (as defined below), an aggregate amount equal to the greater of (i) 25% of the Net Proceeds received from all CVR Transactions (as defined in the STING Agonist CVR Agreement) and (ii) an aggregate amount equal to the product of $1.00 and the total number of shares of Company common stock outstanding as of such record date (not to exceed an aggregate amount of $18.0 million) (the “Target Payment Amount”).
The CVR payment obligation expires on the later of 18 months following the Closing or the
one-year
anniversary of the date of the final database lock of the STING clinical trial (as defined in the STING Agonist CVR Agreement) (the “STING Agonist CVR Expiration Date”). The STING Agonist CVRs are not transferable, except in certain limited circumstances, are not certificated or evidenced by any instrument, do not accrue interest, and are not registered with the Securities and Exchange Commission (the “SEC”) or listed for trading on any exchange. Until the STING Agonist CVR Expiration Date, subject to certain exceptions, the Company is required to use commercially reasonable efforts to (a) complete the STING Trial and (b) pursue a CVR Transaction. The STING Agonist CVR Agreement became effective upon the Closing and, unless terminated earlier in accordance with its terms, will continue in effect until the STING Agonist CVR Expiration Date or all CVR payment amounts are paid pursuant to their terms.
At the Closing, Spring Bank,
F-star
Ltd, a representative of Spring Bank stockholders prior to the Closing, and Computershare Trust Company N.A., as the Rights Agent, also entered into a STING Antagonist Contingent Value Rights Agreement (the “STING Antagonist CVR Agreement”). Pursuant to the Exchange Agreement and the STING Antagonist CVR Agreement, each share of common stock held by Spring Bank stockholders as of November 19, 2020, immediately prior to the Closing, received a dividend of one CVR (“STING Antagonist CVR”) entitling such holders to receive, in connection with the execution of a potential development agreement (the “Approved Development Agreement”) and certain other transactions involving proprietary STING antagonist compound occurring on or prior to the STING Antagonist CVR Expiration Date (as defined below) equal to 80% of all net proceeds (as defined in the STING Antagonist CVR Agreement) received by the Company after the Closing pursuant to (i) the Approved Development Agreement, if any, and (ii) all CVR Transactions (as defined in the STING Antagonist CVR Agreement) entered into prior to the STING Antagonist CVR Expiration Date.
The CVR payment obligations expire on the seventh anniversary of the Closing (the “STING Antagonist CVR Expiration Date”). The STING Antagonist CVRs are not transferable, except in certain limited circumstances, are not certificated or evidenced by any instrument, do not accrue interest, and are not registered with the SEC or listed for trading on any exchange. Until the STING Antagonist CVR Expiration Date, subject to certain exceptions, the Company is required to use commercially reasonable efforts to (a) consummate the Approved Development Agreement, (b) to perform the terms of the Approved Development Agreement and (c) pursue CVR Transactions. The STING Antagonist CVR Agreement became effective upon the Closing and, unless terminated earlier in accordance with its terms, will continue in effect until the STING Antagonist CVR Expiration Date or all CVR payment amounts are paid pursuant to their terms.
8

The acquisition-date fair value of the CVR liability represents the future payments that are contingent upon the achievement of sale or licensing for the product candidates. The fair value of the contingent consideration acquired of $2.5 million as of December 31, 2020 and as of March 31, 2021 is based on the Company’s probability-weighted discounted cash flow assessment that considers probability and timing of future payments. The fair value measurement is based on significant Level 3 unobservable inputs such as the probability of achieving a sale or licensing agreement, anticipated timelines, and discount rate. Changes in the fair value of the liability will be recognized in the consolidated statement of operations and comprehensive loss until settlement.
All issued and outstanding
F-star
Ltd share options
g
ranted under
F-star’s
three legacy equity incentive plans became exercisable in full immediately prior to the Closing. At the Closing, all issued share options and restricted stock units granted by
F-star
Ltd under the
F-star
Therapeutics Limited 2019 Equity Incentive Plan (the “2019 Plan”) were replaced by options (“Replacement Options”) and awards (“Replacement RSUs”), on the same terms (including vesting), for Company common stock, based on the Exchange Ratio.
The Company’s common stock, which was listed on the Nasdaq Capital Market, traded through the close of business on Friday, November 20, 2020 under the ticker symbol “SBPH” and continued trading on the Nasdaq Capital Market, on a post-Reverse Stock Split adjusted basis, under the ticker symbol “FSTX” beginning on Monday, November 23, 2020. Commencing on November 23, 2020, the Company’s common stock was represented by a new CUSIP number, 30315R 107. After the Transaction, the Company had approximately $
30
 million in cash. The combined company is now headquartered out of
F-star
Ltd’s existing facilities in Cambridge, United Kingdom and office in Cambridge, MA.
The Transaction was accounted for as a business combination using the acquisition method of accounting under the provisions of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”), Topic 805,
Business Combinations
(“ASC 805”). The Transaction was accounted for as a reverse acquisition with
F-star
Ltd being deemed the acquiring company for accounting purposes. Under ASC 805,
F-star
Ltd, as the accounting acquirer, recorded the assets acquired and liabilities assumed of Spring Bank in the Transaction at their fair values as of the acquisition date (see Note
2
 of the financial statements).
F-star
Ltd was determined to be the accounting acquirer based on an analysis of the criteria outlined in ASC 805 and the facts and circumstances specific to the Transaction, including the fact that immediately following the Transaction:
(1) F-star
Ltd shareholders owned the majority of the voting rights of the combined company;
(2) F-star
Ltd designated a majority (five of eight) of the initial members of the board of directors of the combined company; and
(3) F-star
Ltd senior management held the key positions in senior management of the combined company. As a result, upon consummation of the Transaction, the historical financial statements of
F-star
Ltd became the historical financial statements of the combined organization.
Liquidity
On March 30, 2021, the Company entered into a Sales Agreement (the “2021 Sales Agreement”) with SVB Leerink LLC (“SVB Leerink”) with respect to an
“at-the-market”
offering as defined in Rule 415 of the Securities Act of 1933, as amended, under which the Company could offer and sell, from time to time in its sole discretion, shares of its common stock, par value $0.0001 per share, having an aggregate offering price of up to $50.0 million through SVB Leerink as its sales agent. As of May 6, 2021, the Company had issued and sold 979,843 shares of common stock for gross proceeds of $9.5 million, resulting in net proceeds of $9.2 million after deducting sales commissions and offering expenses. On May 6, 2021, the Company terminated the 2021 Sales Agreement.
On May 6, 2021, the Company entered into an underwriting agreement with SVB Leerink, as representative of the underwriters, relating to an underwritten public offering of approximately 9.3 million shares of the Company’s common stock, par value $0.0001 per share. The underwritten public offering resulted in gross proceeds of $65.0 million. The Company incurred $3.9 million in issuance costs associated with the underwritten public offering, resulting in net proceeds to the Company of $61.1 million.
On April 1, 2021, the Company, as borrower, entered into a Venture Loan and Security Agreement (the “Loan and Security Agreement”) with Horizon Technology Finance Corporation (“Horizon”), as lender and collateral agent for itself. The Loan and Security Agreement provides for 4 (4) separate and independent $

The Company does not expect to raise any additional funds priorrefer to the completionauthoritative U.S. GAAP as found in the ASC and Accounting Standards Updates (“ASU”) of the Exchange. However, if the Exchange is not completed, the Company may require significant additional funds earlier than it currently expects in order to conduct clinical trials and preclinical and discovery activities. There can be no assurances, however, that additional funding will be available on favorable terms, or at all. To the extent that the Company raises additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interests will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect common stockholder rights. If the Company raises additional funds through collaborations, strategic alliances or licensing arrangements with third parties, the Company may have to relinquish valuable rights to its technologies, future revenue streams, research programs, or product candidates or grant licenses on terms that may not be favorable to the Company.

Included in cash and cash equivalents as of June 30, 2020 are money market fund investments of $7.0 million and included in cash and cash equivalents as of December 31, 2019 are money market fund investments of $21.1 million and United States treasury securities of $6.0 million, which are reported at fair value (see Note 5).

Restricted Cash

As of June 30, 2020 and December 31, 2019, restricted cash consists of approximately $234,000, which is held as a security deposit required in conjunction with a lease agreement for the Company’s principal office and laboratory space entered into in October 2017.

ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company’s leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. This is the rate the Company would have to pay if borrowing on a collateralized basis over a similar term to each lease. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

Impairment of Long-Lived Assets

Long-lived assets to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. When such events occur, the Company compares the carrying amounts of the assets to their undiscounted expected future cash flows. If the undiscounted cash flows are insufficient to recover the carrying value, an impairment loss is recorded for the difference between the carrying value and fair value of the asset. As of June 30, 2020,March 31, 2021, 0

License and collaboration arrangements and revenue recognition
The Company’s revenues are generated primarily through license and collaboration agreements with pharmaceutical and biotechnology companies. The terms of these arrangements may include (i) the grant of intellectual property rights (IP licenses) to therapeutic drug candidates against specified targets, developed using the Company’s proprietary mAb2 bispecific antibody platform, (ii) performing research and development services to optimize drug candidates, and (iii) the grant of options to obtain additional research and development services or licenses for additional targets, or to optimize product candidates, upon the payment of option fees.
The terms of these arrangements typically include payment to the Company of one or more of the following:
non-refundable,
upfront license fees; payments for research and development services; fees upon the exercise of options to obtain additional services or licenses; payments based upon the achievement of defined collaboration objectives; future regulatory and sales-based milestone payments; and royalties on net sales of future products.

The Company has adopted FASB ASC Topic 606,
Revenue from Contracts with Customers
(“ASC 606”). This standard applies to all contracts with customers, except for contracts that are within the scope of other standards, such as leases, insurance, collaboration arrangements and financial instruments. To date, the Company has entered into License and Collaboration Agreements with Denali, and Ares (an affiliate of Merck KGaA, Darmstadt, Germany) which were determined to be within the scope of ASC 606.
Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. In determining the appropriate amount of revenue to be recognized under ASC 606, the Company performs the following steps: (i) identification of the promised goods or services in the contract; (ii) determination as to whether the promised goods or services are performance obligations including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. As part of the accounting for these arrangements, the Company must make significant judgments, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each performance obligation.
Once a contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised within the contract and determines those that are performance obligations. Arrangements that include rights to additional goods or services that are exercisable at a customer’s discretion are generally considered options. The Company assesses if these options provide a material right to the customer and if so, they are considered performance obligations.
Performance obligations are promised goods or services in a contract to transfer a distinct good or service to the customer. The promised goods or services in the Company’s contracts with customers primarily consist of license rights to the Company’s intellectual property for research and development, research and development services, options to acquire additional research and development services, and options to obtain additional licenses, such as a commercialization license for a potential product candidate. Promised goods or services are considered distinct when: (i) the customer can benefit from the good or service on its own or together with other readily available resources; and (ii) the promised good or service is separately identifiable from other promises in the contract.
In assessing whether promised goods or services are distinct, the Company considers factors such as the stage of development of the underlying intellectual property, the capabilities of the customer to develop the intellectual property on their own and whether the required expertise is readily available. In addition, the Company considers whether the collaboration partner can benefit from a promise for its intended purpose without the receipt of the remaining promises, whether the value of the promise is dependent on the unsatisfied promises, whether there are other vendors that could provide the remaining promises, and whether it is separately identifiable from the remaining promises. The Company estimates the transaction price based on the amount of consideration the Company expects to receive for transferring the promised goods or services in the contract. The consideration may include both fixed consideration and variable consideration. At the inception of each arrangement that includes variable consideration, the Company evaluates the amount of the potential payments and the likelihood that the payments will be received. The Company utilizes either the most likely amount method or expected value method to estimate variable consideration to include in the transaction price based on which method better predicts the amount of consideration expected to be received. The amount included in the transaction price is constrained to the amount for which it is probable that a significant reversal of cumulative revenue recognized will not occur. At the end of each subsequent reporting period, the Company
re-evaluates
the estimated variable consideration included in the transaction price and any related constraint, and if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative
catch-up
basis in the period of adjustment.
After the transaction price is determined, it is allocated to the identified performance obligations based on the estimated standalone selling price. The Company must develop assumptions that require judgment to determine the standalone selling price for each performance obligation identified in the contract. The Company utilizes key assumptions to determine the standalone selling price, which may include other comparable transactions, pricing considered in negotiating the transaction, probabilities of technical and regulatory success and the estimated costs. Certain variable consideration is allocated specifically to one or more performance obligations in a contract when the terms of the variable consideration relate to the satisfaction of the performance obligation and the resulting amounts allocated to each performance obligation are consistent with the amounts the Company would expect to receive for each performance obligation.
The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) each performance obligation is satisfied at a point in time or over time, and if over time based on the use of an input method. The Company accounts for contract modifications as a separate contract if both of the following conditions are met:
(i)
the scope of the contract increases because of the addition of promised goods or services that are distinct; and
12

Table of Contents
(ii)
the price of the contract increases by an amount of consideration that reflects standalone selling prices of the additional promised goods or services and any appropriate adjustments to that price to reflect the circumstances of the particular contract.
If a contract modification is deemed to not be a separate contract, then the transaction price is updated and allocated to the remaining performance obligations (both from the existing contract and the modification). Previously recognized revenue for goods and services that are not distinct from the modified goods or services is adjusted based upon an updated measure of progress for the partially satisfied performance obligations.
If a contract modification is deemed to be a separate contract, any revenue recognized under the original contract is not retrospectively adjusted and any performance obligations remaining under the original contract continue to be recognized under the terms of that contract.
The Company’s collaboration revenue arrangements include the following:
Up-front
License Fees: If a license is determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenues from nonrefundable,
up-front
fees allocated to the license when the license is transferred to the licensee and the licensee is able to use and benefit from the license. For licenses that are bundled with other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from
non-refundable,
up-front
fees. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.
Milestone payments: The Company’s collaboration agreements may include development and regulatory milestones. The Company evaluates whether the milestones are considered probable of being reached and estimates the amount to be included in the transaction price using the most likely amount method. The Company evaluates factors such as the scientific, clinical, regulatory, commercial, and other risks that must be overcome to achieve the particular milestone in making this assessment. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within the Company’s control or the licensee’s control, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. At the end of each reporting period, the Company
re-evaluates
the probability of achievement of such milestones and any related constraint, and if necessary, adjusts the estimate of the overall transaction price. Any such adjustments are recorded on a cumulative
catch-up
basis, which would affect collaboration revenue and net loss in the period of adjustment.
Customer Options: The Company evaluates the customer options to obtain additional items (i.e., additional license rights) for material rights, or options to acquire additional goods or services for free or at a discount. Optional future services that reflect their standalone selling prices do not provide the customer with a material right and, therefore, are not considered performance obligations and are accounted for as separate contracts. If optional future services include a material right, they are accounted for as performance obligations. The Company determines an estimated standalone selling price of any material rights for the purpose of allocating the transaction price. The Company considers factors such as the identified discount and the probability that the customer will exercise the option. Amounts allocated to a material right are not recognized as revenue until, at the earliest, the option is exercised or expires.
Royalties: For arrangements that include sales-based royalties, including milestone payments based on a level of sales, and the license is deemed to be the predominant item to which the royalties relate, the Company will recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). To date, the Company has not recognized any revenue related to sales-based royalties or milestone payments based on the level of sales.
Research and Development Costs

Services: The promises under the Company’s collaboration agreements may include research and development services to be performed by the Company on behalf of the partner. Payments or reimbursements resulting from the Company’s research and development efforts are recognized as the services are performed and presented on a gross basis because the Company is the principal for such efforts.

Research and development costs
Research and development costs are expensed as incurred. Research and development expenses consist primarilyare comprised of costs incurred for the Company’s research activities, including discovery efforts, and the development of product candidates, which include:

expenses incurred under agreements with third parties, including contract research organizations, or CROs, that conduct research, preclinical activities and clinical trials on the Company’s behalf as well as contract manufacturing organizations, or CMOs, that manufacture drug products for use in the Company’s preclinical and clinical trials;

salaries, benefits and other related costs, including stock-based compensation expense, for personnel in the Company’s research and development functions;

costs of outside consultants, including their fees, stock-based compensation and related travel expenses;

the cost of laboratory supplies and acquiring, developing and manufacturing preclinical study and clinical trial materials;

costs related to compliance with regulatory requirements; and

facility-related expenses, which include direct depreciation costs and allocated expenses for rent and maintenance of facilities and other operating costs.


The Company expensesin performing research and development activities, including compensation expense, share-based compensation and benefits, facilities costs and laboratory supplies, depreciation, amortization and impairment expense, manufacturing expenses and external costs of outside vendors engaged to conduct preclinical development activities and clinical trials as incurred. The Company recognizes external development costs based on an evaluationwell as the cost of licensing technology. Typically, upfront payments and milestone payments made for the progress to completionlicensing of specific tasks using information provided to the Company by its vendors and its clinical investigative sites. Payments for these activitiestechnology are based on the terms of the individual agreements, which may differ from the pattern of costs incurred, and are reflected in the Company’s consolidated financial statementsexpensed as prepaid or accrued research and development in the period in which they are incurred, except for payments relating for intellectual property rights with future alternative use which will be expensed when the intellectual property is in use. Nonrefundable advance payments for goods or services to be received in the future for use in research and development activities are recorded as prepaid expenses.

The prepaid amounts are expensed as the related goods are delivered or the services are performed.

Warrants

The Company accounts for freestanding warrants within stockholders equity or as liabilities based on the characteristics and provisions of each instrument. The Company evaluates outstanding warrants in accordance with ASC 480, Distinguishing Liabilities from Equity,, and ASC 815, Derivatives and Hedging.Hedging. If none of the criteria in the evaluation in these standards are met, the warrants are classified as a component of stockholdersstockholders’ equity and initially recorded at their grant date fair value without subsequent remeasurement. Warrants that meet the criteria are classified as liabilities and remeasured to their fair value at the end of each reporting period.

Stock-Based Compensation

The Company’s stock-based payments include stock options, performance-based restricted stock units (“performance-based RSUs”), time-based restricted stock units (“time-based RSUs”) and grants of common stock.

The Company accounts for all stock-basedshare-based compensation in accordance with ASC 718, “Compensation – Stock Compensation”(“ASC 718”). ASC 718 requires companies to estimate the fair value of equity-based payment awards granted to employees and nonemployees using a fair value method. The measurement date for employee awards ison the date of grant, and stock-based compensation costs aregrant. The value of the portion of the award that is ultimately expected to vest is recognized as an expense over the employees’ requisite service period which is generallyin the Company’s consolidated statements of operations and comprehensive loss.

For share-based awards granted to

consultants, the measurement date for
non-employee
awards is the date of grant. The compensation expense is then recognized over the requisite service period, which is the vesting period of the respective award.
The Company measuresreviews stock award modifications when there is an exchange of original award for a new award. The Company calculates for the incremental fair value based on the difference between the fair value of the performance-based RSUs relating to the total share return performance using a Monte Carlo valuation model. The Company measuresmodified award and the fair value of the performance-based RSUs relatingoriginal award immediately before it was modified. The Company immediately recognizes the incremental value as compensation cost for vested awards and recognizes, on a prospective basis over the remaining requisite service period, the sum of the incremental compensation cost and any remaining unrecognized compensation cost for the original award on the modification date.
The fair value of stock options (“options”) on the grant date is estimated using the Black-Scholes option-pricing model using the single-option approach. The Black-Scholes option pricing model requires the use of highly subjective and complex assumptions, including the option’s expected term and the price volatility of the underlying stock, to the milestone performance goals usingdetermine the fair value of the award.
Historically, given the absence of an active market for the ordinary shares of
F-star
Ltd, the board of directors determined the estimated fair value of the Company’s equity instruments based on input from management, which utilized the most recently available independent third-party valuation, and considered a number of objective and subjective factors, including external market conditions affecting the biotechnology industry sector. Each valuation methodology included estimates and assumptions that require judgment. These estimates and assumptions included a number of objective and subjective factors in determining the value of
F-star
Ltd ordinary shares at each grant date. The expected volatility for F star Ltd was calculated based on reported volatility data for a representative group of publicly traded companies for which historical information was available. The historical volatility was calculated based on a period of time commensurate with the assumption used for the expected term. The risk-free interest rate was based on the U.S. Treasury yield curve in effect at the time of grant commensurate with the expected term assumption.
F-star
Ltd used the simplified method, under which the expected term is presumed to be the midpoint between the vesting date and the probability thatend of the specified performance criteria willcontractual term.

As a basis for considering market participant assumptions in fair value measurements, ASC 820 establishes a three-tier fair value hierarchy applies only tothat distinguishes between the valuation inputs used in determining the reported fair value of the investments and is not a measure of the investment credit quality. The three levels of the fair value hierarchy are described below:

following:

Level 1—Valuations based on unadjusted quoted1 — Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

liabilities.

Level 2—Valuations based on2 — Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or for which all significantsimilar assets or liabilities, or other inputs that are observable either directly or indirectly.

can be corroborated by observable market data.

Level 3—Valuations that require3 — Unobservable inputs that reflect the Company’s own assumptionsare supported by little or no market activity that are both significant to determining the fair value measurementof the assets or liabilities, including pricing models, discounted cash flow methodologies and unobservable.

similar techniques.

To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.
The Company’s assetscarrying amounts reflected in the consolidated balance sheets for cash and liabilities measured at fair value on a recurring basis include cash equivalents, marketable securities and warrant liabilities.

other current assets, research and development incentives receivable, accounts payable and accrued liabilities and other current liabilities approximate their fair values, due to their short-term nature.

Net Loss Per Share

Basicloss per share

The Company computes net loss per share is computed by dividingin accordance with ASC Topic 260,
Earnings Per Share
(“ASC 260”) and related guidance, which requires two calculations of net (loss) income attributable to the Company’s shareholders per share to be disclosed: basic and diluted. Convertible preferred shares are considered participating securities and are included in the calculation of basic and diluted net loss by(loss) income per share using the weighted-average number of
two-class
method. In periods where the Company reports net losses, such losses are not allocated to the convertible preferred shares of common stock outstanding for the period. computation of basic or diluted net (loss) income.
Diluted net loss(loss) income per share is computed by dividing the same as basic net (loss) income per share for the periods in which the Company had a net loss bybecause the weighted-average numberinclusion of shares of common stock and dilutiveoutstanding common stock equivalents outstandingwould be anti-dilutive.
Income taxes
The Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the period, determined usingexpected future tax consequences of events that have been recognized in the treasury-stock method andconsolidated financial statements or in the as if-converted method, for convertible securities, if inclusion of these instruments is dilutive.

For the three and six months ended June 30, 2020 and 2019, both methods are equivalent. Basic and diluted net loss per share is described further in Note 2.

Income Taxes

Deferred tax assets and liabilities are determined based uponon the basis of the differences between the consolidated financial statement carrying amountsstatements and the tax basis of existing assets and liabilities as well as net operating loss and tax credit carryforwards using enacted tax rates expected to be in effect infor the yearsyear in which the differences are expected to reverse. DeferredChanges in deferred tax assets and liabilities are reduced by a valuation allowance ifrecorded in the provision for income taxes. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent it believes, based upon the weight of available evidence, that it is more likely than not that someall or a portion or all of the deferred tax assetassets will not be realized.

realized, a valuation allowance is established through a charge to income tax expense. Potential for recovery of deferred tax assets is evaluated by estimating the future taxable profits expected and considering prudent and feasible tax planning strategies.

The Company assesses its income tax positions and records tax benefits based upon management’s evaluation ofaccounts for uncertainty the facts, circumstances and information available atconsolidated financial statements by applying a
two-step
process to determine the reporting date. For those tax positions where it is more likely than not that a tax benefit will be sustained, the Company records the largest amount of tax benefit with a greater than 50%to be recognized. First, the tax position must be evaluated to determine the likelihood of being realized upon ultimate settlement with a taxing authority having full knowledge of all relevant information. For those income tax positions wherethat it is not more likely than not that a tax benefit will be sustained 0upon external examination by the taxing authorities. If the tax position is deemed

to be sustained, the tax position is then assessed to determine the amount of benefit is recognizedto recognize in the consolidated financial statements. The Company classifiesamount of the benefit that may be recognized is the largest amount that will more likely than not be realized upon ultimate settlement. Any provision for income taxes includes the effects of any resulting tax reserves, or unrecognized tax benefits, that are considered appropriate as well as the related net interest and penalties associated with such uncertainpenalties.

The U.K. research and development tax credit is payable to the Company after surrendering tax losses and is not dependent on current or future taxable income. As a result, it is not reflected as part of the income tax provision If, in the future, any UK research and development tax credits generated are utilized to offset a corporate income tax liability in the United Kingdom, that portion would be recorded as a benefit within the income tax provision and any refundable portion not dependent on taxable income would continue to be recorded as a reduction to research and development expenses.

2. NET LOSS PER SHARE

Business Combination

As described in Note 1, on November 20, 2020,
F-star
Ltd completed a business combination with Spring Bank. For accounting purposes, the purchase price was based on (i) the fair value of Spring Bank common stock as of the Transaction date of $21.5 million, which was determined based on the number of shares of common stock issued in connection with the Transaction, and (ii) the portion of the fair value attributable to
in-the-money
fully and partially vested stock options and warrants.
Under the acquisition method of accounting, the total purchase price is allocated to the acquired tangible and intangible assets and assumed liabilities based on their fair values as of the acquisition date. Any excess purchase price over the fair value of assets acquired and liabilities assumed is allocated to goodwill. Acquired
in-process
research and development assets will be classified as indefinite-lived intangible assets and will be amortized over their estimated useful economic lives when put into use. The fair values of acquired
in-process
research and development assets were calculated using an income approach based on the expected future cash flows associated with the respective asset using an estimated discount rate of 14%. In addition, on the date of the Transaction, there were 73,337 outstanding equity classified warrants with a fair value of $0.2 million and 408,444 outstanding liability classified warrants with a fair value of $0.2 million.
Goodwill is allocated to one reporting unit. The goodwill was primarily attributable to the access
F-star
gained to a public listing on the Nasdaq Capital Market. The Company determined that the underlying goodwill and intangible assets are not deductible for tax purposes.
For the year ended December 31, 2020, the Company incurred acquisition-related expenses of approximately $4.2 million, which are included in general and administrative expenses. The purchase price is allocated to the fair value of assets and liabilities acquired as follows (in thousands, except shares of common stock and fair value per share):

The following tables present information about the three and six months ended June 30, 2019 was $88,000 and $171,000, respectively.

5. FAIR VALUE MEASUREMENTS

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) 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 are performed in a manner to maximize the use of observable inputs and minimize the use of unobservable inputs.

The Company classified its money market funds within Level 1 because their fair values are based on their quoted market prices. The Company classified its United States treasury securities and fixed income securities within Level 2 because their fair values are determined using alternative pricing sources or models that utilized market observable inputs.



A summary of theCompany’s financial assets and liabilities that are measured at fair value ason a recurring basis and indicate the level of June 30, 2020 and December 31, 2019 is as followsthe fair value hierarchy utilized to determine such fair values (in thousands):

shareholders approved the 2019 Plan. The initial maximum number of ordinary shares that could be issued under the 2019 Plan was 2,327,736. This number consisted of 1,922,241 new ordinary shares and 405,495 new ordinary shares as replacements for grants under the previous

This plan grants the beneficiaries participation rights only, beneficiaries would receive a proportion of the exit proceeds realized by shareholders, but the plan does not grant the right to purchase shares. The transfer of the participation rights occurred at the same exchange ratio as used for the exchange of GmbH shares for shares issued by

Awards granted under the 2019 Plan generally vest over a
four-year service period with 28% of the award vesting on the first anniversary of the commencement date and the balance vesting monthly over the remaining three years. Awards generally expire 10 years from the date of the grant. For certain senior members of management and directors, the board of directors approved an alternative vesting schedule.
As result of the Transaction, the share reserve automatically increased on January 1
st
of the year following the year in which a Nasdaq listing occurred, in an amount equal to 4% of the total number of shares outstanding as of December 31 of the preceding year. As a result, there were additional 364,005 shares to be issued for the 2019 plan. As of March 31, 2021, there were 67,986 shares available for issuance under the 2019 Plan.
In conjunction with the Transaction, all issued and outstanding
F-star
Ltd share options granted under the three
F-star
Ltd legacy equity incentive plans became exercisable in full immediately prior to the Closing. At the Closing, all issued share options and RSUs granted by
F-star
Ltd under the 2019 Plan were replaced by the Replacement Options and Replacement RSUs on the same terms (including vesting), for Company common stock, based on the Exchange Ratio. The Company determined that the exchange of
F-star
Ltd awards for the Company entered intoawards would be accounted for as a Controlled Equity OfferingSMSales Agreement (the “Sales Agreement”)modification of awards under ASC 718. The Company concluded that the modification would not affect the number of awards expected to vest or the service period over which compensation expense related to awards would be recognized, since the vesting schedule applicable to each Replacement Option would be the same as the vesting schedule applicable to the original option that it replaced. In addition, the Replacement RSUs and Replacement Options are subject to substantially the same terms and conditions as the original RSUs and original options, respectively, and did not provide holders of the Replacement Options or Replacement RSUs with Cantor Fitzgerald & Co. (“Cantor”), pursuant to whichany additional benefits that the holders did not have under their original options or original RSUs. In addition, the fair value of an award tranche immediately after modification was less than the fair value of that award tranche immediately before modification. Therefore, total compensation cost recognized for the Replacement RSUs and Replacement Options equaled the grant-date fair value of the original awards, and the Company may offer and sell, from timecontinues to time through Cantor, sharesrecognize the grant date fair values of the Company’s common stock having an aggregate offering price of up to $50.0 million. The Company pays Cantor a commission rate equal to 3.0% of the aggregate gross proceeds from each sale. During the threemodified awards over their respective service periods.

During the three and six months ended June 30, 2019, the Company sold an aggregate of 600 shares of its common stock pursuant to the Sales Agreement at a weighted-average selling price of $10.03 per share, which resulted in de minimis net proceeds to the Company.

The market approach exams observable market values for similar assets or securities. The cost approach uses the concept of replacement cost as an indicator of value and the notion that an investor would pay no more for an asset that what it would cost to replace the asset with one of equal utility. After the Closing of the Transaction, the fair value of the common stock onCompany’s Common Stock is used to estimate the datefair value of grant.

Restricted Stock Units

Performance-Based Restricted Stock Units

In January 2019, the Company issued performance-based RSUs to senior management under the Amended and Restated 2015 Plan that represented shares potentially issuable in the future subject to the satisfaction of certain performance milestones as well as a service condition. The vesting of 50% of the performance-based RSUs was based upon the Company’s performance relative to a peer group over a two-year performance period, from January 1, 2019 through December 31, 2020, measured by the Company’s relative total shareholder return. The vesting of 25% of the performance-based RSUs was based on the achievement of a performance goal milestone as of December 31, 2019 and the vesting of the remaining 25% of the performance-based RSUs was based upon the achievement of a performance goal milestone as of December 31, 2020.

The Company estimated the fair value of total shareholder return performance-based RSUs at the date of grant using a Monte Carlo valuation methodology and amortizes those fair values over the requisite service period for each separately vesting tranche of the award. The Monte Carlo methodology that the Company uses to estimate the fair value of total shareholder return performance-based RSUs at the date of grant incorporates into the valuation the possibility that the market condition may not be satisfied. Provided that the requisite service is rendered, the total fair value of options vested during the total shareholder return performance-based RSUs at the date of grant must be recognized as compensation expense even if the market condition is not achieved. However, the number of shares that ultimately vest can vary significantly with the performance of the specified market criteria.


The Company estimates the fair value of milestone performance-based RSUs at the date of grant using the fair value methodthree months ended March 31, 2021 and the probability that the specified performance criteria will be met and amortizes the fair value over the requisite service period for each separately vesting tranche of the award when attainment of the milestone is deemed probable. The assumption used to determine the fair value of the performance-based RSUs granted to management in 2019 for the performance goal milestone units is based on the market price of the award on the grant date. Each quarter the Company updates its assessment of the probability that the specified criteria will be achieved and adjusts its estimate of the fair value, if necessary.

As of December 31, 2019, the Company did not meet the 2019 milestone under the performance-based RSUs, and accordingly 46,450 shares were returned to the Amended and Restated 2015 Plan. The previously recognized expense of $0.3 million related to the 2019 milestone was reversed during the year ended December 31, 2019. The 2020, milestone was not deemed probable,$2.8 million and the previously recognized expense of $0.1$2.0 million, was reversed during the year ended December 31, 2019. The Company recognized $0.3 million expense related to the total shareholder return component of the performance-based RSUs during the year ended December 31, 2019.

In March 2020, the Company and the recipients of these performance-based RSUs agreed to cancel the agreements and as a result, 139,350 shares were returned to the Amended and Restated 2015 Plan. The Company recognized the remaining expense for the total shareholder return performance-based RSUs in the amount of $0.3 million during the six months ended June 30, 2020. The Company did not recognize any expense related to the milestone performance-based RSUs.

In April 2020,February 2021, the Company issued 360,000 performance-based RSUs to senior management under the Amended and Restated 2015 Plan that represented shares potentially issuable in the future subject to the satisfaction of certain performance milestones. The vesting of 50% of the performance-based RSUs is based on the achievement of a performance goal milestone as of December 31, 2020 and the vesting of the remaining 50% of the performance-based RSUs is based upon the achievement of a performance goal milestone as of December 31, 2021. For the three and six months ended June 30, 2020, the Company recognized approximately $44,000 expense related to the performance-based RSUs.

License and collaboration agreement with Denali Therapeutics Inc.
Summary
In August 2016, Biotechnology,
F-star
Gamma Limited (a related party until May 30, 2018)
(“F-star
Gamma”), and GmbH entered into a license and collaboration agreement (the “Denali LCA”) with Denali. The goal of the collaboration was the development of certain constant Fc domains of an antibody with
non-native
antigen binding activity (“Fcabs”), to enhance delivery of therapeutics across the blood brain barrier into the brain. The collaboration was designed to leverage
F-star
Gamma’s modular antibody technology and Denali’s expertise in the development of therapies for neurodegenerative diseases. In connection with the entry into the collaboration agreement, Denali also purchased from the
F-star
Gamma shareholders an option, which was referred to as the
buy-out-option,
to acquire all of the outstanding shares of
F-star
Gamma pursuant to a
pre-negotiated
share purchase agreement.
On May 30, 2018, Denali exercised such
buy-out
option and entered into a share purchase agreement (the “Purchase Agreement”) with the shareholders of
F-star
Gamma and Shareholder Representative Services LLC, pursuant to which Denali acquired all of the outstanding shares of
F-star
Gamma (the “Acquisition”).
As a result of June 30, 2020the Acquisition,
F-star
Gamma has become a wholly owned subsidiary of Denali and Denali changed the entity’s name to Denali BBB Holding Limited. In addition, Denali became a direct licensee of certain of
F-star’s
intellectual property (by way of Denali’s assumption of
F-star
Gamma’s license agreement with Biotechnology (the
“F-star
Gamma License”)). Denali made initial exercise payments to Biotechnology and the former shareholders of
F-star
Gamma under the Purchase Agreement and the
F-star
Gamma License, in the aggregate, of $18.0 million, less the net liabilities of
F-star
Gamma, which were approximately $0.2 million. $4.0 million was payable to the Company. In addition, Denali is required to make future contingent payments, to the Company and the former shareholders of
F-star
Gamma, with a maximum aggregate of $437.0 million upon the achievement of certain defined preclinical, clinical, regulatory, and commercial milestones. Of this total, a maximum of $91.4 million is payable to the Company. The total amount of the contingent payments varies, based on whether the Company delivers an Fcab that meets
pre-defined
criteria and whether the Fcab has been identified solely by the Company or solely by Denali or jointly by the Company and Denali.
Under the terms of the Denali LCA, Denali was granted the right to nominate up to three Fcab targets for approval (“Accepted Fcab Targets”), within the first three years of the date of the agreement. Upon entering into the Denali LCA, Denali had selected transferrin receptor as the first Accepted Fcab Target and paid an upfront fee of $5.5 million to
F-star
Gamma, which included selection of the first Accepted Fcab Target. In May 2018, Denali exercised its right to nominate two additional Fcab targets and identified a second Accepted Fcab Target. Denali made a
one-time
payment to the
F-star
group for the two additional Accepted Fcab Targets of $6.0 million and extended the time period for its selection of the third Accepted Fcab Target until August 2020.
Denali also agreed to be responsible for certain research costs incurred by
F-star
in conducting activities under each agreed development plan for up to 24 months.
Under the terms of the Denali LCA,
F-star
Gamma was prohibited from developing, commercializing and manufacturing any antibody or other molecule that incorporated any Fcab directed to an Accepted Fcab Target, or any such Fcab as a standalone product, and from authorizing any third party to take any such action.
Revenue recognition
The Company has considered the performance obligations identified in the contracts and concluded that the grant of intellectual property rights is not distinct from the provision of R&D services, as the R&D services are expected to significantly modify the early-stage intellectual property. As a result, the grant of intellectual property rights and the provision of R&D services has been combined into a single performance obligation for this contract.

The initial transaction price for first Accepted Fcab Target was deemed to be $7.1 million consisting of $5.0 million for the grant of intellectual property rights and $2.1 million for R&D services, and $5.1 million for the second Accepted Fcab Target consisting of $3.0 million for the grant of intellectual property rights and $2.1 million for R&D services.

9. CONVERTIBLE TERM LOAN

In September 2019, the Company entered into a Convertible Term Loan with Pontifax Medison Finance (Israel) L.P. and Pontifax Medison Finance (Cayman) L.P., as lenders, and Pontifax Medison Finance GP, L.P., in its capacity as administrative agent and collateral agent for itself and the lenders (collectively, the “Lenders”), providing for a $20.0 million term loan (the “Convertible Term Loan”), which the Company received on September 19, 2019 (the “Closing Date”). The Company incurred issuance costs of $0.4 million and Pontifax Warrants costs of $0.6 million. The Convertible Term Loan issuance costs and Pontifax Warrant costs are shown as an offset to the Convertible Term Loan on the balance sheet and are amortized using the effective interest method to interest expense through September 23, 2023 (the “Maturity Date”). In April 2020, the Company entered into a prepayment notice and pay-off letter with the Lenders, which providedtransaction price for the full repayment in cashfirst Accepted Fcab was increased to $6.6 million due to achievement of a $1.5 million milestone that on initial recognition of the $20.0 million Convertible Term Loan and amended the exercise price with respect to the Pontifax Warrants. Upon repayment of the Convertible Term Loan, the Company incurred a loss on extinguishment of debt, which included $0.3 million for a prepayment fee, $0.4 million of unamortized issuance costs, $0.5 million in unamortized Pontifax Warrant costs and approximately $54,000 for the Pontifax Warrant amendment (see Note 7).

Pursuant to the Convertible Term Loan, the Companycontract was entitled, at its option, to prepay some or all of the then outstanding principal balance and all accrued and unpaid interest on the Convertible Term Loan, together with a prepayment charge equal to 3% of the principal amount being prepaid.The Lenders were entitled, at their option, to elect to convert the then outstanding Convertible Term Loan amount and all accrued and unpaid interest thereon into shares of the Company’s common stock at a conversion price of $8.76 per share.

The Company’s obligations were secured by a security interest, senior to any current and future debts and to any security interest, in all of the Company’s right, title, and interest in, to and under all of its property and other assets, subject to limited exceptions including the Company’s intellectual property. The Convertible Term Loan contained customary events of default, representations, warranties and covenants, including a material adverse effect clause. The Company was required to maintain a minimum cash balance of $7.0 million in its accounts.

Upon the occurrence of an event of default, a default interest rate of an additional 4% per annum would have been applied to the outstanding loan balances, and the Lenders would have been able to declare all outstanding obligations immediately due and payable and exercise all of its rights and remedies as set forth in the Convertible Term Loan and under applicable law. The Company evaluated the accounting for the Convertible Term Loan and identified an embedded derivative related to the contingent interest feature. The Company determined the fair value of the contingent interest feature to be de minimis.

In addition, the Company issued the Lenders warrants to purchase an aggregate of 250,000 shares of the Company’s common stock (the “Pontifax Warrants”). The Pontifax Warrants are exercisable for a period of six years from the Closing Date and were exercisable at an exercise price of $6.57 per share prior to their amendment in April 2020. The aggregate fair value of the Pontifax Warrants on the date of issuance was approximately $0.6 million and was recorded as a discount to the term loan and will be amortized over the life of the term loan using the effective interest rate method. The aggregate fair value remaining on the payoff date was $0.5 million and wasnot included in the loss on extinguishmenttransaction price, as it was not deemed probable that a reversal would not occur in a future reporting period.

All performance obligations in respect of the Convertible Term Loan upon repayment. In connection withfirst Accepted Fcab Target identified in the repayment of the Convertible Term Loan, the Pontifax Warrantscontract were amended and restateddeemed to amend the exercise price to $2.08 per share, which was equal to 1.5 times the weighted-average closing price of the Company’s Common Stockhave been fully satisfied during the 90 days prior to the repayment date. All other terms of the Pontifax Warrants remained the same. year ended December 31, 2019.
During the three months ended March 31, 2021 and 2020, the Company recognized $0.1 million and $0.5 million, respectively, over time in respect of the second Accepted Fcab target.
2019 License and collaboration agreement with Ares Trading S.A.
In June 30, 2020, there2017, Delta entered into an LCA and an Option Agreement with Ares (the “Ares LCA”). The purpose of the Ares LCA was an


incremental expense of approximately $54,000 for the amendmentcompanies to collaborate on the development of tetravalent bispecific antibodies against five drug target pairs. The Option Agreement granted Ares a call option to acquire the entire issued share capital of Delta. Under the Ares LCA, Delta was obligated to use commercially reasonable efforts to perform research and development activities on the five selected target pairs, under mutually agreed research plans. The activities were governed by a joint steering committee formed by an equal number of representatives from both parties.

On May 14, 2019, the Ares LCA agreement with Ares was amended and restated to convert the existing purchase option over the entire share capital of Delta to an intellectual property licensing arrangement that included the exclusive grant of development and exploitation rights to one tetravalent bispecific antibody directed against immuno-oncology targets and the option to acquire the exclusive right to an additional antibody. As part of the Pontifax Warrantamended Ares LCA, Delta gained exclusive rights to FS118, now
F-star’s
lead product candidate, which is currently in a
proof-of-concept
clinical trial. As discussed further below, this amended and restated Ares LCA was accounted for a separate contract, rather than a contract amendment.
For the exclusive rights granted in relation to the first molecule, an option fee of $11.1 million was paid by Ares to Delta. Following receipt of the option fee, Ares becomes responsible for the development of the molecule and development, regulatory and sales-based royalties become payable to Company upon achievement of specified events. Delta is eligible to receive $71.6 million in development milestones and $83.9 million in regulatory milestones.
For the second antibody included within the amended and restated agreement, Delta is obliged to perform research activities under plans agreed by both parties. Ares will pay for all R&D costs half-yearly in advance until the company delivers the data package specified in the research plan. Ares can then elect to pay a fee of $14.0 million to exercise price,their option to take an exclusive intellectual property license, which allows them to control the development and exploitation of the molecule. Following receipt of the option fee, Ares is responsible for the development of the molecule and development, regulatory and sales-based royalties become payable to Delta upon achievement of specified events. Delta is eligible to receive $48.7 million in development milestones and $61.6 million in regulatory milestones.
Development milestone payments are triggered upon achievement by each product candidate of a defined stage of clinical development and regulatory milestone payments are triggered upon approval to market a product candidate by the U.S. Food and Drug Administration or other global regulatory authorities. Sales-based milestones are payable based upon aggregate annual worldwide net sales in all indications of all licensed products. Delta is eligible to receive $168.0 million in sales-based milestones. In addition, to the extent that any product candidates covered by the exclusive licenses granted to Ares are commercialized, Delta will be entitled to receive a single digit royalty based on a percentage of net sales on a
country-by-country
basis.
On July 15, 2020, a deed of amendment (the “2020 Amendment”) was enacted in respect of the May 13, 2019, amendment to the Ares LCA. The 2020 Amendment had two main purposes (i) to grant additional options to acquire intellectual property rights for a further two molecules; and (ii) to allow Ares to exercise its option early to acquire intellectual property rights to the second molecule included in the lossagreement as well as to terminate the R&D services.
Revenue recognition
Management has considered the performance obligations identified in the contracts and concluded that the option for the grant of intellectual property rights is not distinct from the provision of R&D services in the agreements, as the R&D services are expected to significantly modify the early-stage intellectual property. As a result, the option for the grant of intellectual property rights and the provision of R&D services has been combined into a single performance obligation for all molecules under the original contract and each individual molecule included in the May 13, 2019 amendment to the Ares LCA. The Company recognizes revenue using the
cost-to-cost
method, which it believes best depicts the transfer of control of the services to the customer. Under the
cost-to-cost
method, the extent of progress towards completion is measured based on extinguishmentthe ratio of debt (see Note 7).

actual costs incurred to the total estimated costs expected upon satisfying the identified performance obligation.

All performance obligations in the original Ares LCA were deemed to have been fully satisfied on termination of the original Ares LCA on May 13, 2019, and no further revenue is expected to be recognized. The total transaction price for the Ares LCA, as amended, was initially determined to be $15.4 million, consisting of the upfront payment and research and development funding for the research term. Variable consideration to be paid to the company upon reaching certain milestones had been excluded from the calculation, as at the inception of the contract, it was not probable that a significant reversal of revenue recognized would not occur in a subsequent reporting period.
23

Table of Contents
There were two components identified in the 2020 Amendment, each of which was accounted for as a separate performance obligation. The grant of the additional options to acquire intellectual property rights was deemed to be distinct, as the customer can benefit from it on its own, and it is independent of the delivery of other performance obligations in the original contract. Additionally, as the amount of consideration reflects a standalone selling price, the Company determined that the second component is accounted for as a separate contract.
In the three months ended March 31, 2021, $0.9 million was recognized in relation to the first antibody included in the 2020 Amendment.
The second component that allows the customer to exercise its option to acquire intellectual property rights early is considered to be a modification of the original contract, as the option is not independent of the R&D services provided under the original contract, and therefore the goods and services are not distinct. The Company updated the transaction price and measure of progress for the performance obligation relating to this molecule.
As a result of the 2020 Amendment, the maximum amount payable by Ares on the achievement of certain development and regulatory milestones in the aggregate was increased to $479.3 million, and the maximum amount payable on the achievement of certain commercial milestones was increased to $295.7 million.
In the three months ended March 31, 2021, Ares provided notice of its intention to exercise its option granted under the 2020 Amendment to acquire the intellectual property rights for an additional molecule. $2.7 million was recognized at a point in time in respect of the option exercise.

Overview

We are

F-star
Therapeutics, Inc.
(collectively with its subsidiaries,
“F-star”
or the “Company”) is a clinical-stage biopharmaceutical company engageddedicated to developing next generation immunotherapies to transform the lives of patients with cancer.
F-star’s
goal is to offer patients better and more durable benefits than currently available immuno-oncology treatments by developing medicines that seek to block tumor immune evasion. Through our proprietary tetravalent, bispecific natural antibody (mAb²
) format, our mission is to generate highly differentiated medicines with monoclonal antibody-like manufacturability, good safety and tolerability. With four distinct binding sites in a natural human antibody format, we believe that our proprietary technology will overcome many of the discoverychallenges facing current immuno-oncology therapies, due to the strong pharmacology enabled by tetravalent bispecific binding.
F-star’s
most advanced product candidate, FS118, is currently being evaluated in a
proof-of-concept
Phase 2 trial in
PD-1/PD-L1
acquired resistance head and developmentneck cancer patients. FS118 is a tetravalent mAb
2
bispecific antibody targeting two receptors,
PD-L1
and
LAG-3,
both of novel therapeuticswhich are established pivotal targets in immuno-oncology. Phase 1 data from 43 heavily
pre-treated
patients with advanced cancer, who have failed
PD-1/PD-L1
therapy, showed that administration of FS118 was well-tolerated with no dose limiting toxicities up to 20 mg/kg. In addition, a disease control rate (“DCR”), defined as either a complete response, partial response or stable disease, of 49% was observed in 39 evaluable patients receiving dose levels of FS118 of 1mg/kg or greater. In acquired resistance patients, DCR was 59% (16 out of 27 patients) and long-term (greater than six months) disease control was observed in six of these patients. We expect to provide an update from the
proof-of-concept
Phase 2 trial in
PD-1/PD-L1
acquired resistance head and neck cancer patients in H1 2022.
F-star’s
second product candidate, FS120, aims to improve checkpoint inhibitor and chemotherapy outcomes and is a mAb2 bispecific antibody that is designed to bind to and stimulate OX40 and CD137, two proteins found on the surface of T cells that both function to enhance T cell activity.
F-star
is developing FS120 alone and in combination with
PD-1/PD-L1
therapy for the treatment of tumors where
PD-1/PD-L1
products are approved, and which have
co-expression
of OX40 and CD137 in the tumor microenvironment.
F-star
initiated a rangePhase 1 clinical trial in patients with advanced cancers in the fourth quarter of cancers2020 and inflammatory diseases using our proprietary small molecule nucleotide platform. We design our compoundsplan to selectively targetprovide an update on the accelerated dose titration phase of this study in
mid-2021.
F-star’s
third product candidate, FS222, aims to improve outcomes in low
PD-L1
expressing tumors and modulate the activity of specific proteins implicated in various disease states. Our internally-developed programs are primarilyis a mAb2 bispecific antibody that is designed to stimulate and/or dampen immune responses. target both the costimulatory CD137 and the inhibitory
PD-L1
receptors, which are
co-expressed
in a number of tumor types.
F-star
initiated a Phase 1 clinical trial in patients with advanced cancers for FS222 in late 2020. We are devoting our resourcesbelieve there is a strong rationale to advancing multiple programscombine FS222 with other anti-cancer agents, including targeted therapy and chemotherapy, and this can be done within the Phase 1 study. We expect to report an update on this study in our STING product portfolio, including our STINGlate 2021.
SB 11285, which
F-star
acquired pursuant to a business combination with Spring Bank Pharmaceuticals, Inc. (“Spring Bank”), is a next generation cyclic dinucleotide STimulator of INterferon Gene (“STING”) agonist clinical program in oncology, our STING antagonist compounds for inflammatory diseases, and our STING agonist antibody drug conjugate (ADC) program for oncology. We are also in the process of evaluating our portfolio of RIG-I agonist and STING agonist compoundsdesigned to improve checkpoint inhibition outcomes as potential therapeutics and vaccine adjuvants for SARS-CoV-2, the virus responsible for COVID-19.

Until January 2020, we had been developing inarigivir soproxil, an orally-administered investigational selective immunomodulator, as a potential treatment for chronic hepatitis B virus, or HBV. In April 2019, we launched two Phase 2 global trials (CATALYST 1 and CATALYST 2) examining the administration of inarigivir 400mg as monotherapy and co-administered with a nucleotide in naïve and virally suppressed chronic HBV patients. On January 29, 2020, we announced that we were terminating all clinical development of inarigivirimmunotherapeutic compound for the treatment of HBV dueselected cancers.

F-star
is conducting an open-label, dose-escalation Phase 1 clinical trial with SB 11285 as an IV administered monotherapy, and in combination with an
anti-PD-L1
antibody, in patients with advanced solid tumors.
F-star
expects to report an update in
mid-2021.

F-star
Ltd (each a share exchange agreement, or“Seller”, and collectively with holders of
F-star
Ltd securities who subsequently became parties to the Exchange Agreement, with the “Sellers”). Pursuant to the Exchange Agreement, each ordinary share of
F-star Therapeutics Limited, or
Ltd outstanding immediately prior to the closing of the Transaction (the “Closing”) was exchanged by the Sellers that owned such
F-star
Ltd shares for a private company registered in Englandnumber of duly authorized, validly issued, fully paid and Wales, and the holders
non-assessable
shares of issued shares in the capital of F-star and the holders of convertible notes of F-star,Company common stock pursuant to which, subject to the satisfaction or waiver of the conditionsan exchange ratio formula as set forth in the Exchange Agreement we will acquire(the “Exchange Ratio”), rounded to the entire issuednearest whole share capital of F-star,Company common stock (after aggregating all fractional shares of Company common stock issuable to such Seller). Also, on November 20, 2020, in connection with, F-star Therapeutics, Inc.and prior to continue as the combined company, which we collectively refer to as the Exchange. Upon completion of, the Exchange,Transaction, Spring Bank Pharmaceuticals,effected a
1-for-4
reverse stock split of its common stock (the “Reverse Stock Split”) and, following the completion of the Transaction, changed its name to
F-star
Therapeutics, Inc. Following the completion of the Transaction, the business of the Company became the business conducted by
F-star,
which is a clinical-stage immuno-oncology company focused on cancer treatment through its proprietary tetravalent bispecific antibody programs. Unless otherwise noted, all references to share amounts in this report reflect the Reverse Stock Split.
Under the terms of the Exchange Agreement, at the Closing, Spring Bank issued an aggregate of 4,620,618 shares of its common stock to
F-star
Ltd stockholders, based on an Exchange Ratio of 0.1125 shares of Spring Bank common stock for each
F-star
Ltd ordinary share, stock option and restricted stock unit (“RSU”) outstanding immediately prior to the Closing. The Exchange Ratio was determined through arms-length negotiations between Spring Bank and
F-star
Ltd pursuant to a formula set forth in the Exchange Agreement.
Pursuant to the Exchange Agreement, immediately prior to the Closing, certain investors in
F-star
Ltd purchased $15.0 million of
F-star
Ltd ordinary shares (the
“Pre-Closing
Financing”). These ordinary shares of
F-star
Ltd were then exchanged at the Closing for shares of the Company’s common stock in the Transaction at the Exchange Ratio.
Pursuant to the Exchange Agreement, all outstanding options to purchase Spring Bank common stock were accelerated immediately prior to the Closing and each outstanding option with an exercise price greater than the closing price of the stock on the Closing Date was exercised in full and all other outstanding options to purchase Company common stock were cancelled effective as of the Closing Date.
Immediately following the Reverse Stock Split and the Closing, there were approximately 4,449,559 shares of Spring Bank common stock outstanding. Following the Closing, the
F-star
Ltd stockholders beneficially owned approximately 53.7% of the combined company’s common stock, and the existing stockholders of Spring Bank beneficially owned approximately 46.3% of the combined company’s common stock. Concurrently with the execution of the Exchange Agreement, certain officers and directors of Spring Bank and
F-star
Ltd and certain stockholders of
F-star
Ltd entered into
lock-up
agreements, pursuant to which they agreed to certain restrictions on transfers of any shares of the Company’s common stock for the
180-day
period following the Closing, other than the shares of the Company’s common stock received in exchange for ordinary shares of
F-star
Ltd subscribed for in the
Pre-Closing
Financing and pursuant to certain other limited exceptions.
In addition, at the Closing, Spring Bank,
F-star
Ltd, a representative of Spring Bank stockholders prior to the Closing, and Computershare Trust Company N.A., as the Rights Agent, entered into a STING Agonist Contingent Value Rights Agreement (the “STING Agonist CVR Agreement”). Pursuant to the Exchange Agreement and the STING Agonist CVR Agreement, each
pre-Reverse
Stock Split share of Spring Bank common stock held by stockholders as of the record date on November 19, 2020, immediately prior to the Closing, received a dividend of one contingent value right (“CVR”) (“STING Agonist CVR”), payable on a
pre-Reverse
Stock Split basis, entitling such holders to receive, in connection with certain transactions involving proprietary STING agonist compound designated as SB 11285 occurring on or prior to the STING Agonist CVR Expiration Date (as defined below) that resulted in aggregate Net Proceeds (as defined in the STING Agonist CVR Agreement) at least equal to the Target Payment Amount (as defined below), an aggregate amount equal to the greater of (i) 25% of the Net Proceeds received from all CVR Transactions (as defined in the STING Agonist CVR Agreement) and (ii) an aggregate amount equal to the product of $1.00 and the total number of shares of Company common stock outstanding as of such record date (not to exceed an aggregate amount of $18.0 million) (the “Target Payment Amount”).
The CVR payment obligation expires on the later of 18 months following the Closing or the
one-year
anniversary of the date of the final database lock of the STING clinical trial (as defined in the STING Agonist CVR Agreement) (the “STING Agonist CVR Expiration Date”). The STING Agonist CVRs are not transferable, except in certain limited circumstances, are not certificated or evidenced by any instrument, do not accrue interest and are not registered with the SEC or listed for trading on any exchange. Until the STING Agonist CVR Expiration Date, subject to certain exceptions, the Company is required to use commercially reasonable efforts to (a) complete the STING Trial and (b) pursue a CVR Transaction. The STING Agonist CVR Agreement became effective upon the Closing and, unless terminated earlier in accordance with its terms, will continue in effect until the STING Agonist CVR Expiration Date the payment or all CVR payment amounts are paid pursuant to their terms.

Impact of
COVID-19
on our intravenously (IV)-administered STING agonist product candidate, as well as other preclinical activities as described below.

Spring Bank Development Programs

The pandemic caused by an outbreak of a newBusiness

In March 2020, the World Health Organization declared the novel strain of coronavirus or
(“COVID-19”)
a pandemic and recommended containment and mitigation measures worldwide. The
COVID-19
pandemic has been evolving, and to date has led to the implementation of various responses, including government-imposed quarantines, travel restrictions and other public health safety measures.
Management continues to closely monitor the impact of the
COVID-19
pandemic that is affectingon all aspects of the U.S.business, including how it will impact operations and global economy and financial markets is also impacting our employees, patients, communitiesthe operations of customers, vendors, and business operations.partners. Management took action in April 2020 to temporarily furlough some of its workforce and took advantage of the U.K. Government Coronavirus Job Retention Scheme that provided funding to businesses with furloughed staff. The fullgrant funding available covered 80% of furloughed employees’ wages plus employer National Insurance and pension contributions up to a maximum of £2,500 per month per furloughed employee. From December 2020 to April 2021, the U.K. government imposed a third national “lockdown”, severely impacting on
day-to-day
activities. The onset of the global pandemic and consequent government-imposed restrictions resulted in a three to
six-month
delay in the operationalization of our clinical trials for FS118, FS120, FS222 and SB 11285. The extent to which the
COVID-19 pandemic will directly or indirectly impact
impacts our future business, results of operationsoperation and financial condition will depend on future developments, thatwhich are highly uncertain and cannot be accurately predicted includingwith confidence at this time, such as the continued duration of the outbreak, new information that may emerge concerning the severity or other strains of
COVID-19
or the effectiveness of actions to contain
COVID-19
or treat its impact, among others. If the Company or any of the third parties with which we engage, however, were to experience shutdowns or other business disruptions, the ability to conduct business in the manner and on the timelines presently planned could be materially and negatively affected, which could have a material adverse impact on our business, results of operation and financial condition. The estimates of the impact on the Company’s business may change based on new information that may emerge concerning
COVID-19
and the actions taken to contain it or treat its impact and the economic impact on local, regional, national, and international markets.
Management is actively monitoring this situation and the possible effects on our financial condition, liquidity, operations, suppliers, industry, and workforce. In the paragraphshas not identified any triggering events that follow, we have described impacts of the COVID-19 pandemic on our clinical and preclinical development programs.

We are developing our lead STING agonist product candidate, SB 11285, as a next-generation immunotherapeutic agent for the treatment of selected cancers. SB 11285 is currently being evaluated as an intravenously (IV)-administered monotherapywould result in a Phase 1a/1b multicenter, dose escalation clinical trial in patients with advanced solid tumors. Phase 1a of this trial is a dose-escalation study with IV SB 11285 monotherapy which allows combination with a checkpoint inhibitor after the completion of the first two cohorts of the trial. Phase 1b of this trial is designed to explore IV SB 11285 antitumor activity in combination with a checkpoint inhibitor in tumor types expected to be responsive to immunotherapy. In February 2020, we entered into a clinical collaboration with Roche for the use of Roche’s PD-L1 checkpoint inhibitor atezolizumab (Tecentriq®)any significant impairment losses in the combination cohortscarrying values of this trial.

We initiated dosing in the initial monotherapy cohort of this Phase 1 trial in the fourth quarter of 2019. Although several of the institutions involved in the conduct of this trial have suspended patient enrollment in all of their clinical trials due to the COVID-19 pandemic, we have been able to continue dosing patients in this trial at two key sites and just recently completed the dosing of patients in the third cohort. Depending on whether we are able to continue enrolling and dosing patients in this Phase 1 trial, we plan to complete the fourth monotherapy cohort by the end of the third or early fourth quarter of 2020. Also, we expect to initiate the first combination cohort examining the co-administration of SB 11285 and atezolizumab by the end of summer 2020. We anticipate that we will announce monotherapy data in the fourth quarter of 2020 and generate sufficient data from our Phase 1a/1b IV STING agonist program by the end of the first half of 2021 to enable advancement into a Phase 2 clinical trial. While the company currently anticipates this Phase 1 trial will remain open and currently enrolled patients will continue on study, all clinical sites activated for the study may determine to stop enrolling and/or dosing patientsassets as a result of the impactpandemic and are not aware of any specific related event or circumstance that would require management to revise estimates reflected in our consolidated financial statements.

Recent Developments
Loan and Security Agreement
On April 1, 2021, the COVID-19 pandemic, which has the potential to impact both the advancement into combination cohorts and the availability of data in 2020 and the first half of 2021.

ADCs represent a novel platform to enable the targeted delivery of payload molecules. Conjugation of a payload molecule to an antibody that has its own efficacy profile could allow for a single drug with enhanced potency and safety compared to either mechanism alone. We believe the chemistry used to develop our STING agonists is differentiated from first generation STING agonists because preclinical studies have shown that our molecules allow for site-specific conjugation to other therapeutic modalities, including antibodies, to form ADCs. Our STING agonists, in combination with an antibody to form an ADC, could provide targeted delivery to the tumor site to better achieve anti-tumor efficacy.

We are also exploring the use of our novel STING antagonist compounds for the treatment of certain autoimmune and inflammatory diseases where the STING pathway is involved. Our STING antagonists are selectively designed to block aberrant activation of the STING pathway, which contributes to the causes of certain autoimmune and inflammatory diseases, including STING-associated vasculopathy with onset in infancy (SAVI), systemic lupus erythematosus (SLE) and other proinflammatory-mediated diseases. In July 2019, we presented preclinical data from a novel STING antagonist compound, which showed potent inhibition of interferon and pro-inflammatory cytokines in wild type and mutant STING in vitro models. In vivo administration of this compound antagonized STING-agonist-induced interferon and cytokine production in the blood, spleen and liver in mice, illustrating the potential that this compound has for therapeutic applications in interferonopathies, as well as autoimmune and inflammatory diseases. Furthermore, in August 2019, weCompany entered into a researchVenture Loan and Security Agreement (the “Loan and Security Agreement”) with Horizon Technology Finance Corporation (“Horizon”) as lender and collateral agent for itself. The Loan and Security Agreement provides for four (4) separate and independent $2.5 million term loans (“Loan A”, “Loan B”, “Loan C”, and “Loan D”) (with each of Loan A, Loan B, Loan C and Loan D, individually a “Term Loan” and, collectively, the “Term Loans”), whereby upon the satisfaction of all the conditions to the funding of the Term Loans, each Term Loan would be delivered by Horizon to the Company in the following manner: (i) Loan A was to be delivered by Horizon to the Company prior to April 1, 2021, (ii) Loan B was required to be delivered by Horizon to the Company prior to April 1, 2021, (iii) Loan C is required to be delivered by Horizon to the Company prior to June 30, 2021, and (iv) Loan D is required to be delivered by Horizon to the Company prior to June 30, 2021. The Company may only use the proceeds of the Term Loans for working capital or general corporate purposes as contemplated by the Loan and Security Agreement. The Company drew down $5 million on April 1, 2021.

The term note matures on the
48-month
anniversary following the funding date. The principal balance the Term Loan bears a floating interest. The interest rate is calculated initially and, thereafter, each calendar month as the sum of (a) the per annum rate of interest from time to time published in The Wall Street Journal as contemplated by the Loan and Security Agreement, or any successor publication thereto, as the “prime rate” then in effect, plus (b) 6.25%; provided that, in the event such rate of interest is less than 3.25%, such rate shall be deemed to be 3.25% for purposes of calculating the interest rate. Interest is payable on a monthly basis based on each Term Loan principal amount outstanding the preceding month.
The Company may, at its option upon at least five business days’ written notice to Horizon, prepay all or any portion of the outstanding Term Loan by simultaneously paying to Horizon an amount equal to (i) any accrued and unpaid interest on the outstanding principal balance of the Term Loan so prepaid; plus (ii) an amount equal to (A) if such Term Loan is prepaid on or before the Loan Amortization Date (as defined in the Loan and Security Agreement) applicable to such Term Loan, three percent of the then outstanding principal balance of such Term Loan, (B) if such Term Loan is prepaid after the Loan Amortization Date applicable to such Term Loan, but on or before the date that is12 months after such Loan Amortization Date, two percent of the then outstanding principal balance of such Term Loan, or (C) if such Term Loan is prepaid more than 12 months after the Loan Amortization Date applicable to such Term Loan, one percent of the then outstanding principal balance of such Term Loan; plus (iii) the outstanding principal balance of such Term Loan; plus (iv) all other sums, if any, that had become due and payable under the Loan and Security Agreement.
In connection with the entry into the Loan and Security Agreement, the Company issued to Horizon warrants (each, individually, a “Warrant” and, collectively, the “Warrants”) to purchase an aggregate number of shares of the Company’s common stock in an amount equal to $100,000 divided by the price for each respective Warrant. If at any time the Company files a registration statement relating to an offering for its own account, or the account of others, of any of its equity securities, the Company agreed to include such number of shares underlying the Warrants in that registration statement as requested by the holder.

Sales Agreement and Underwriting Agreement
On March 30, 2021, the Company entered into a Sales Agreement (the “2021 Sales Agreement”) with SVB Leerink LLC (“SVB Leerink”) with respect to an
”at-the-market”
offering, as defined in Rule 415 of the Securities Act of 1933, as amended, under which the Company could offer and sell, from time to time in its sole discretion, shares of its common stock, par value $0.0001 per share, having an aggregate offering price of up to $50.0 million (the “Placement Shares”) through SVB Leerink as its sales agent.
Upon delivery of a placement notice in April 2021, and subject to the terms and conditions of the 2021 Sales Agreement, SVB Leerink began to sell the Placement Shares. The Company agreed to pay SVB Leerink a commission equal to three percent of the gross sales proceeds of any Placement Shares sold through SVB Leerink under the 2021 Sales Agreement, and also provided SVB Leerink with customary indemnification and contribution rights. As of May 6, 2021, the Company had issued and sold 979,843 shares, for gross proceeds of $9.5 million, resulting in net proceeds of $9.2 million after deducting sales commissions. On May 6, 2021, the Company terminated the 2021 Sales Agreement.
On May 6, 2021, the Company entered into an underwriting agreement with SVB Leerink, as representative of the Universityunderwriters, relating to an underwritten public offering of Texas

Financial Operations Overview
License revenue
To date, we have devoted substantially all of our resources to research and development efforts, including conducting clinical trials for our product candidates, protecting our intellectual property and providing general and administrative support for these operations. We have not generated any revenue to date other than from grants from the National Institutes of Health, or NIH. No additional funding remains available to us under any grant for the development of any of our product candidates. We have funded our operations primarily through proceeds received from private placements of convertible notes, common stock and/or warrants; the exercise of optionssales, and warrants; NIH grant funding; and public offerings of securities.

We have incurred significant annual net operating losses in every year since our inception andwe do not expect to continue to incur significant expenses and net operating lossesgenerate any revenue from product sales for the foreseeable future. Our net lossesrevenue consists of collaboration revenue under our license and collaboration agreements with Ares Trading S.A. (“Ares”) and Denali Therapeutics, Inc. (“Denali”), including amounts that are recognized related to upfront payments, milestone payments, option exercise payments, and amounts due to us for research and development services. In the three and six months ended June 30, 2020 were $6.5 million and $14.7 million, respectively, and our net losses for the three and six months ended June 30, 2019 were $4.6 million and $9.8 million, respectively. As of June 30, 2020, we had an accumulated deficit of $140.9 million. Our net losses may fluctuate significantly from quarter to quarter and year to year. We expect to continue to incur significant expenses and increasing operating losses for the next several years.

We do not expect to raise any additional funds prior to the completion of the Exchange. However, if the Exchange is not completed, we may require significant additional funds earlier than we currently expect in order to conduct clinical trials and preclinical and discovery activities. There can be no assurances, however, that additional funding will be available on favorable terms, or at all. To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’ ownership interests will be diluted, and the terms of these securitiesfuture, revenue may include liquidation or other preferences that adversely affect common stockholder rights. If we raisenew collaboration agreements, additional funds through collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights tomilestone payments, option exercise payments, and royalties on any net product sales under our technologies, future revenue streams, research programs, or product candidates or grant licenses on terms that may not be favorable to us.

There is no guarantee that the Exchange will be completed. As of June 30, 2020, we had $23.5 million in cash, cash equivalents and marketable securities.collaborations. We expect that our cash, cash equivalentsany revenue we generate will fluctuate from period to period as a result of the timing and marketable securities asamount of June 30, 2020 will be sufficient to fund operations for at least the next twelve months. This estimate assumes no additional funding from new collaboration agreements, equity financings or further sales under our Controlled Equity OfferingSM Sales Agreement with Cantor Fitzgerald & Co.

milestone payments made for the licensing of technology are expensed as research and development in the period in which they are incurred, except for payments relating for intellectual property rights with future alternative use which will be expensed when the intellectual property is in use.
Non-refundable
advance payments for goods or services to be received in the future for use in research and development activities are recorded as prepaid expenses. The prepaid amounts are expensed as the related goods are delivered or the services are performed.

Critical Accounting Policies and Significant Judgments and Estimates

Our consolidated financial statements are prepared in accordance with generally accepted accounting principles2020, the Company was subject to corporate taxation in the United States, United Kingdom and Austria.

Our U.K.-established entities have generated losses and some profits in the United Kingdom since inception and have therefore not paid significant U.K. corporation tax.

The preparationcorporation tax benefit (tax) presented in the Company’s statements of our consolidated financial statementscomprehensive income (loss) represents the tax impact from its operating activities in the United States, United Kingdom and related disclosures requires our managementAustria, which have generated taxable income in certain periods. As the entities located in the United Kingdom carry out extensive research and development activities, they seek to benefit from the U.K. research and development tax credit cash rebate regime known as the Small and
Medium-sized
Enterprises R&D Tax Credit Program (the “SME Program”). Qualifying expenditures largely comprise employment costs for research staff, consumables expenses incurred under agreements with third parties that conduct research and development, preclinical activities, clinical activities and manufacturing on the Company’s behalf and certain internal overhead costs incurred as part of research projects. No research and development activities are carried out in Austria, so the Company is not able to utilize the research and development premium available under the Austrian corporation tax regime.
The tax credit received in the United Kingdom pursuant to the SME Program permits companies to deduct an extra 130% of their qualifying costs from their yearly profit or loss, as well as the normal 100% deduction, to make estimatesa total 230% deduction. If the company is incurring losses, it is entitled to claim a tax credit worth up to 14.5% of the surrenderable loss. To qualify for relief under the SME Program, companies are required to employ fewer than 500 staff and assumptions that affecthave a turnover of under €100.0 million or a balance sheet total of less than €86.0 million.
The U.K. government has released draft legislation to introduce a cap on the reported amount of assets,the payable credit that a qualifying loss-making small and
medium-sized
enterprise business can receive through research and development relief in any one year. The cap would be applied to restrict payable credit claims in excess of £20,000 with effect for accounting periods beginning on or after April 2021 by reference to, broadly, three times the total employee payroll tax and social security liabilities revenue, costsof the company. The draft legislation also contains an exemption which prevents the cap from applying. That exemption requires the company to be creating, or taking steps to create, intellectual property as well as having research and expenses and related disclosures. We believe thatdevelopment expenditure in respect of connected parties which does not exceed 15% of the estimates and assumptions underlying the accounting policies described therein maytotal claimed. The Company does not expect this legislation, if adopted, to have the greatest potentiala material impact on our consolidated financial statementsits payable credit claims based on amounts currently claimed.
Research and therefore, consider thesedevelopment tax credits received in the United Kingdom are recorded as a reduction in research and development expenses. The U.K. research and development tax credit is payable to companies after surrendering tax losses and is not dependent on current or future taxable income. As a result, it is not reflected as part of the income tax provision. If, in the future, any U.K. research and development tax credits generated are utilized to offset a corporate income tax liability in the United Kingdom, that portion would be recorded as a benefit within the income tax provision, and any refundable portion not dependent on taxable income would continue to be our critical accounting policies.

Income tax expense was relatively flat compared to the three months ended March 31, 2020.
In the event the Company generates revenues in the future, the Company may benefit from the United Kingdom “patent box” regime that allows profits attributable to revenues from patents or patented products to be taxed at an effective rate of 10%.

Accrued Research and Development Expenses

As part of the process of preparing our consolidated financial statements, we are required to estimate our accrued research and development expenses. This process involves reviewing open contracts and purchase orders, communicating with our personnel to identify services that have been performed on our behalf and estimating the level of service performed and the associated costs incurred for the services when we have not yet been invoiced or otherwise notified of the actual costs. The majority of our service providers invoice us in arrears for services performed, on a predetermined schedule or when contractual milestones are met; however, some require advanced payments. We make estimates of our accrued expenses as of each balance sheet date in our consolidated financial statements based on facts and circumstances known to us at that time. Examples of estimated accrued research and development expenses include fees paid to:

CROs in connection with performing research services on our behalf and clinical trials;

investigative sites or other providers in connection with clinical trials;

vendors in connection with preclinical and clinical development activities; and

CROs in connection with performing research services on our behalf and clinical trials;

vendors related to product manufacturing, development and distribution of preclinical and clinical supplies.

investigative sites or other providers in connection with clinical trials;
vendors in connection with preclinical and clinical development activities; and
vendors related to product manufacturing, development and distribution of preclinical and clinical supplies.
We base our expenses related to preclinical studies and clinical trials on our estimates of the services received and efforts expended pursuant to quotes and contracts with multiple CROs that conduct and manage clinical trials on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the clinical expense. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completion of clinical trial milestones. In accruing service fees, we estimate the time period over which services will be performed, enrollment of patients, number of sites activated and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or amount of prepaid expense accordingly. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may result in us reporting amounts that are too high or too low in any particular period. To date, we have not made any material adjustments to our prior estimates of accrued research and development expenses.


Contingent value rights

Warrants Issued in 2016 Private Placement

In connection with our private placement offering in November 2016, or the November private placement, we issued warrants to purchase 1,644,737 shares of common stock, which we refer to as the November 2016 Warrants. These warrants are exercisable at an exercise price of $10.79 per share. We evaluated the terms of these warrants and concluded that they should be liability-classified. In November 2016, we recorded the

Share-based compensation
The Company accounts for share-based compensation in accordance with ASC 718, “Compensation – Stock Compensation” (“ASC 718”).

The value of the notesportion of the award that is ultimately expected to vest is recognized as an expense over the unaudited financial statements included elsewhere in this Quarterly Report on Form 10-Q.

Stock-Based Compensation

We issue stock-based awards to employees and non-employees, generallyrequisite service period in the form of stock options or performance-based restricted stock units. We account for our stock-based compensation awards in accordance with Financial Accounting Standards Board, (FASB) ASC Topic 718, Compensation—Stock Compensation, or ASC 718. ASC 718 requires all stock-based payments to employees and non-employees, including grants of employee stock options and modifications to existing stock awards, to be recognized in theCompany’s consolidated statements of operations and comprehensive loss based on their fair values.

We expect to continue to do so until suchcompanies for which historical information was available. The historical volatility is calculated based on a period of time as we have adequate historical data regardingcommensurate with the volatility of our traded stock price.

The assumptions used to determine the fair value of the time-based RSUs granted to management during the six months ended June 30, 2020 is based on the market price of the award on the grant date, which was a weighted average fair value for the six months ended June 30, 2020 of $1.41 per share.

These assumptions represent our best estimates, but the estimates involve inherent uncertainties and the application of our judgment. As a result, if factors change and we use significantly different assumptions or estimates, our stock-based compensation expense could be materially different. We recognize compensation expense for only the portion of awards that are expected to vest.


The impact of our stock-based compensation expense for stock options and performance based restricted stock units granted to employees and non-employees may grow in future periods if the fair value of our common stock increases.

JOBS Act

In April 2012,Income in 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 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, as an EGC, we could have delayed the adoption of certain accounting standards until those standards would otherwise apply to private companies. However, we irrevocably elected not to avail ourselves of this extended transition period and, as a result, we will adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for other public companies.

Subject to certain conditions, as an EGC, we intend to rely on certain exemptions afforded by the JOBS Act, including the exemption from certain requirements related to the disclosure of executive compensation in our periodic reports and proxy statements, and the requirement that we hold a nonbinding advisory vote on executive compensation and any golden parachute payments; the requirement that the auditors provide an attestation report on our system of internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act; and complying with any requirement that may be adopted by the Public Company Accounting Oversight Board, or PCAOB, regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements, known as the auditor discussion and analysis. We will remain an EGC until the earliest of the last day of the fiscal yearsame manner in which we have total annual gross revenues of approximately $1.07 billionthe award recipient’s payroll costs are classified or more;in which the last day of the fiscal year following the fifth anniversary of the date of the completion of the closing of our initial public offering, or IPO, which is December 31, 2021; the date on which we have issued more than $1 billion in nonconvertible debt during the previous three years; or the date on which weaward recipient’s service payments are deemed to be a large accelerated filer under the rules of the SEC.

Liquidity and Capital Resources

Sources of Liquidity

liquidity

From our inception through June 30, 2020,March 31, 2021, we have not generated any revenue from product sales, and we have incurred significant operating losses and negative cash flows from our operations. We do not expect to generate significant revenue from sales of any products for several years, if at all.
As of March 31, 2021, the Company had an accumulated deficit of $57.0 million, cash of $3.7 million, and accounts payable and accrued expenses of $11.1 million. The future success of the Company is dependent on its ability to successfully obtain additional working capital, obtain regulatory approval for and successfully launch and commercialize its product candidates and to ultimately attain profitable operations.
Historically, we have financed our operations throughprimarily with proceeds from the issuance of ordinary and convertible preferred shares, proceeds from issuances in connection with a convertible note facility, proceeds received from private placementsupfront payments and development milestone payments in connection with our collaboration arrangements, and payments received for research and development services. We expect this historical financing trend to continue if and until we are able obtain regulatory approval for and successfully commercialize one or more of convertible notes, common stock and/our drug candidates, although there can be no assurance that we will obtain regulatory approval or warrants,successfully commercialize any of our current or planned future product candidates.
On March 30, 2021, the exercise of options and warrants, NIH grant funding and public offerings of securities. As of June 30, 2020, we had cash, cash equivalents and marketable securities totaling $23.5 million and an accumulated deficit of $140.9 million.

We pay Cantor a commission rate equal to 3.0%million through SVB Leerink as its sales agent. As of May 6, 2021, the Company had issued and sold 979,843 shares, for gross proceeds of $9.5 million, resulting in net proceeds of $9.2 million after deducting sales commissions. On May 6, 2021, the Company terminated the 2021 Sales Agreement.
On May 6, 2021, the Company entered into an underwriting agreement with SVB Leerink, as representative of the aggregateunderwriters, relating to an underwritten public offering of approximately 9.3 million shares of the Company’s common stock, par value $0.0001 per share. The underwritten public offering resulted in gross proceeds from each sale. Shares sold under the Sales Agreement were offered and sold pursuant to our Registration Statement on Form S-3 (Registration No. 333-218399) that was declared effective by the SEC on June 12, 2017, which we refer to as the S-3 Registration Statement, and a prospectus supplement and accompanying base prospectus that we filedof $65.0 million. The Company incurred $3.9 million in issuance costs associated with the SEC on August 18, 2017. During the three and six months ended June 30, 2020, we sold an aggregate of 649,095 and 690,895 shares of our common stock, respectively, pursuant to the Sales Agreement at a weighted-average selling price of $1.32 per share, during both periods, which resulted in approximately $0.8 millionunderwritten public offering, resulting in net proceeds to the Company during both periods. Duringof $61.1 million.
On April 1, 2021, the year ended December 31, 2019, we sold an aggregate of 600 shares of our common stock under the Sales Agreement at a weighted average selling price of $10.03 per share, which resulted in de minimis net proceeds.

In September 2019, weCompany, as borrower, entered into a loanthe Loan and security agreementSecurity Agreement with certain affiliates of Pontifax MedisonHorizon Technology Finance or the Lenders, that providedCorporation, as lender and collateral agent for a $20.0itself. The Loan and Security Agreement provides for four (4) separate and independent $2.5 million term loanloans (“Loan A”, “Loan B”, “Loan C”, and bears annual interest at“Loan D”) (with each of Loan A, Loan B, Loan C and Loan D, individually a rate“Term Loan” and, collectively, the “Term Loans”), whereby upon the satisfaction of 8.0%, which we referall the conditions to as the Convertiblefunding of the Term Loan. The ConvertibleLoans, each Term Loan provided for interest-only payments for twenty-four monthswould be delivered by Horizon to the Company in the following manner: (i) Loan A was to be delivered by Horizon to the Company prior to April 1, 2021, (ii) Loan B was required to be delivered by Horizon to the Company prior to April 1, 2021, (iii) Loan C is required to be delivered by Horizon to the Company prior to June 30, 2021, and repayment(iv) Loan D is required to be delivered by Horizon to the Company prior to June 30, 2021.

The Lenders could have, at their option, elected to convert some or all of the then outstanding term loan amount and all accrued and unpaid interest thereon into shares of our common stock at a conversion price of $8.76 per share.

On April 8, 2020, we entered into a prepayment notice and pay-off letter with the Lenders, which provided for the full repayment in cashCompany drew down $5 million on April 8, 2020 of our $20.0 million Convertible Term Loan. The pay-off letter provided that the repayment amount would be approximately $20.3 million, which included payment in full of all outstanding principal and accrued interest underlying the Convertible Term Loan and $0.3 million for a prepayment fee. Pursuant to the pay-off letter, all of our indebtedness and obligations to the Lenders were discharged in full, and all security interests and other liens held by the Lenders as security for the Convertible Term Loan terminated upon the Lenders’ receipt of the repayment amount.In connection with the repayment of the Convertible Term Loan, the warrants previously issued to the lenders were amended and restated so that the new exercise price is $2.08, which was equal to 1.5 times the weighted-average closing price of our common stock during the 90 days prior to the repayment date and resulted in an incremental expense of approximately $54,000. All other terms and conditions of the Pontifax Warrants remain the same.

We made the decision to repay the Convertible Term Loan as a result of changes in our operating needs following our announcement in the first quarter of 2020 that we were discontinuing the development of our HBV program, as well as the cost of capital associated with the Convertible Term Loan.

other sources. There are no assurances, however, that the Company will be successful in raising additional working capital, or if it is able to raise additional working capital, it may be unable to do so on commercially favorable terms. The Company’s failure to raise capital or enter into other such arrangements if and when needed would have a negative impact on its business, results of operations and financial condition and its ability to develop its product candidates

Our future capital requirements as a stand-alone company, if the proposed Exchange were not to be completed, are difficult to forecast. Our future funding requirements will depend on many factors, including, but not limited to:

the continued clinical development of SB 11285, our lead STING agonist product candidate;

including:

the costs involved in conducting preclinical and clinical activities for our STING and COVID-19 programs;

the costs of preparing, filing, and prosecuting patent applications and maintaining, enforcing and defending intellectual property-related claims;

the extent to which we may elect to continue product development activities in the future, if at all; and

the timing and completion of the Exchange.

Critical Accounting Policies and Significant Judgments and Estimates
Our consolidated financial statements are prepared in accordance with United States generally accepted accounting principles. The preparation of our consolidated financial statements and related disclosures requires our management to make estimates and assumptions that affect the reported amount of assets, liabilities, revenue, costs and expenses and related disclosures. We believe that the estimates and assumptions underlying the accounting policies described therein may have the greatest potential impact on our consolidated financial statements and, therefore, consider these to be adversely affected byour critical accounting policies. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these current estimates based on different assumptions and under different conditions. There have been no material changes to the uncertaintyCompany’s critical accounting policies and volatilityestimates as discussed in the U.S. capital markets relating toCompany’s Annual Report on Form
10-K
for the ongoing COVID-19 pandemic. In addition,year ended December 31, 2020, filed with the terms of any financing may adversely affect the holdings or the rights of our stockholders. For example, if we raise additional funds by issuing equity securities or by selling convertible debt securities, further dilution to our existing stockholders may result. In addition, pursuant to the instructions to Form S-3, if we file a new S-3 shelf registration statement, we would only have the ability to sell shares under such registration statement, during any 12-month period, in an amount less than or equal to one-third of the aggregate market value of our common stock held by non-affiliates, which is commonly referred to as our “public float.” If adequate funds are not available, we may be required to obtain funds through collaborators that may require us to relinquish rights to our technologies or drug candidates that we might otherwise seek to develop or commercialize independently.

Contractual Obligations and Commitments

In September 2019, we entered into the Convertible Term Loan with the Lenders that provided for a $20.0 million term loan with an annual interest rate of 8.0%. The Convertible Term Loan provided for interest-only payments for twenty-four months and repayment of the aggregate outstanding principal balance of the term loan in quarterly installments starting upon expiration of the interest only period and continuing through September 19, 2023. On April 8, 2020, we entered into a prepayment notice and pay-off letter with the Lenders, which provided for the full repayment in cash on April 8, 2020 of the Convertible Term Loan. Pursuant to the pay-off letter, all of our indebtedness and obligations to the Lenders were discharged in full, and all security interests and other liens held by the Lenders as security for the Loan terminated upon the Lenders’ receipt of the repayment amount. The Convertible Term Loan and the subsequent repayment are described in Note 9 to the notes to the consolidated financial statements contained in this Quarterly Report on Form 10-Q.

We enter into contracts in the normal course of business with third partythird-party service providers for clinical trials, preclinical research studies and testing, manufacturing and other services and products for operating purposes. We have not included our payment obligations under these contracts in the table as these contracts generally provide for termination upon notice, and therefore, we believe that our
non-cancelable
obligations under these agreements are not material and we cannot reasonably estimate the timing of if and when they will occur. We could also enter into additional research, manufacturing, supplier and other agreements in the future, which may require
up-front
payments and even long-term commitments of cash.

Sheet Arrangements

We did not have during the periods presented, and we do not currently have, any

Item 3.

Quantitative and Qualitative Disclosures About Market Risk.

We are exposed to market risk related to changes in interest rates. Our cash, cash equivalents and marketable securities of $23.5 million as of June 30, 2020, consisted of cash, cash equivalents and marketable securities. Our primary exposure to market risk is interest income sensitivity, which is affected by changes in the general level of U.S. interest rates. However, because a significant amount of the marketable securities in our investment portfolio are short-term in nature, an immediate 10% change in market interest rates would not be expected to have a material impact on the fair market value of our investment portfolio or on ourCompany’s financial condition orposition and results of operations.

Controls and Procedures.

Evaluation of Disclosure Controls

Emerging Growth Company and Procedures

Our management, with the participation of our principal executive officer and our principal financial officer, evaluated, as of the end of the period covered by this Quarterly Report on Form 10-Q, the effectiveness of our disclosure controls and procedures. Based on that evaluation of our disclosure controls and procedures as of June 30, 2020, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures as of such dateSmaller Reporting Company Status

We are effective at the reasonable assurance level. The term “disclosure controls and procedures,”an emerging growth company, (“EGC”) as defined in Rules 13a-15(e) and 15d-15(e) the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). We will remain an EGC until the earlier of (1) the last day of the fiscal year following the fifth anniversary of the completion of our initial public offering (December 31, 2021), (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” as defined in Rule
12b-2
under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which would occur if the market value of our ordinary shares held by
non-affiliates
exceeded $700.0 million as of the last business day of the second fiscal quarter of such fiscal year or (4) the date on which we have issued more than $1.0 billion in
non-convertible
debt securities during the prior three-year period. The JOBS Act permits an EGC to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies until those standards would otherwise apply to private companies. We have irrevocably elected to “opt out” of this provision and, as a result, we will comply with new or revised accounting standards when they are required to be adopted by public companies that are not emerging growth companies. In addition, we intend to rely on the other exemptions and reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, we are entitled to rely on certain exemptions as an EGC we are not required to, among other things, (i) provide an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404(b), (ii) provide all of the compensation disclosure that may be required of
non-emerging
growth public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act, (iii) comply with any requirement that has or may be adopted by the Public Company

Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (auditor discussion and analysis), and (iv) disclose certain executive compensation-related items such as the correlation between executive compensation and performance and comparisons of the chief executive officer’s compensation to median employee compensation. These exemptions will apply for a period of five years following the completion of Spring Bank’s initial public offering (December 31, 2021) or until we no longer meet the requirements of being an EGC, whichever is earlier.
We are also a smaller reporting company as defined under the Exchange Act. We may take advantage of certain of the scaled disclosures available to smaller reporting companies and will be able to take advantage of these scaled disclosures for so long as (i) our voting and
non-voting
common stock held by
non-affiliates
is less than $250.0 million measured on the last business day of our second fiscal quarter or (ii) our annual revenue is less than $100.0 million during the most recently completed fiscal year and our voting and
non-voting
common stock held by
non-affiliates
is less than $700.0 million measured on the last business day of our second fiscal quarter.

Controls and Procedures.
Evaluation of Disclosure Controls and Procedures
As of March 31, 2021, our management, under the supervision of our Chief Executive Officer and Chief Financial Officer, performed an evaluation of the effectiveness of our disclosure controls and other procedures of a company that are designedas defined in Rules
13a-15(e)
and
15d-15(e)
under the Exchange Act to ensure that information required to be disclosed by a companythe Company in the reports that it files or submits under the Exchange Act areis recorded, processed, summarized and reported within the time periods specified inby the SEC’sSEC rules and forms. Disclosure controlsforms, and procedures include, without limitation, controls and procedures designed to ensure that such information required to be disclosed by us in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive officerChief Executive Officer and principal financial and accounting officer,Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Management recognizes that anyBased on this evaluation, our Chief Executive Officer and Chief Financial Officer due the material weaknesses in our internal controls as previously disclosed in our Annual Report on Form 10-k for the year ended December 31, 20220, as described below, our disclosure controls and procedures no matter how well designed and operated, can provide only reasonable assurancewere not effective as of achieving their objectives andMarch 31, 2021.
Management’s Annual Report on Internal Control over Financial Reporting
We have performed an evaluation of the effectiveness of our internal control over financial reporting, based on criteria established by the Committee of Sponsoring Organizations of the Treadway Commission in its 2013 Internal Control-Integrated Framework. Based on that evaluation, our management, necessarily applies its judgmentincluding our Chief Executive Officer and Chief Financial Officer, concluded that our internal control over financial reporting was not effective as of March 31, 2021, due to material weaknesses in evaluatinginternal control over financial reporting, associated with (i) the cost-benefit relationshiplack of possibleformal policies and procedures and sufficient complement of personnel to implement effective segregation of duties and (ii) the lack of sufficient formality and evidence of controls over key reports and procedures.

Inherent Limitationsspreadsheets.

A material weakness is a deficiency, or a combination of Internal Controls

deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of a company’s annual or interim financial statements will not be prevented or detected on a timely basis.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Projections of any evaluation of effectiveness to future periodsyears 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.

As an EGC under the JOBS Act, we are exempt from the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002.
Remediation Plans
As discussed above, the material weaknesses over effective controls on the financial statement close and reporting process as well as lack of an effective control environment with formal processes and procedures and not having sufficient formality and evidence of controls as of December 31, 2020, were not remediated as of March 31, 2021. We have commenced measures to remediate these material weaknesses and have hired additional finance and accounting personnel during the fourth quarter of 2020 with appropriate expertise to perform specific functions which we believe will allow for proper segregation of duties, design key controls and implement improved processes and internal controls. We will continue to assess our finance and accounting staffing needs to ensure remediation of these material weaknesses. The material weaknesses will not be considered remediated until the applicable remedial controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively.
Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules
13a-15(f)
and
15d-15(f)
under the Exchange Act) during the sixthree months ended June 30, 2020,March 31, 2021, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

As a result

Table of the COVID-19 pandemic, in March 2020, certain of our employees began working remotely. We have not identified any material changes in our internal control over financial reporting as a result of these changes to the working environment. We are continually monitoring and assessing the COVID-19 situation to determine any potential impacts on the design and operating effectiveness of our internal controls over financial reporting.

From time to time, we may become involved in legal proceedings arising in the ordinary course of our business. We are not presently a party to any material litigation.

Item 1A.

Risk Factors.

In addition to the other information set forth in this report, you should carefully consider the risk factors discussed in Part I, Item 1A.1A, “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2019, or2020, as filed with the Form 10-K, and in Part II, Item 1A of our Quarterly ReportSEC on Form 10-Q for the quarter ended March 31, 2020,30, 2021, which could materially affect our business, financial condition, or results of operations. Other than the addition of the following risk factors, thereThere have been no material changes in or additions to the risk factors referred to in the previous sentence.

Risks Related to the Exchange

The issuance of our common stock in the Exchange pursuant to the Exchange Agreement must be approved by our stockholders. Failure to obtain this approval and failure of any other closing conditions to the Exchange Agreement would prevent the Closing of the Exchange.

Before the Exchange can be completed, our stockholders must approve the Exchange. Failure to obtain the required stockholder approval may result in a material delay in, or the abandonment of, the Exchange. Even if the Exchange is approved by the our stockholders, certain other specified conditions set forth in the Exchange Agreement must be satisfied or waived to complete the Exchange. We cannot assure you that all of the conditions will be satisfied or waived. If the conditions are not satisfied or waived, the Exchange will not occur or will be delayed, and we may lose some or all of the intended benefits of the Exchange. Any delay in completing the Exchange may materially adversely affect the timing and benefits that are expected to be achieved from the Exchange.

The Exchange Ratio set forth in the Exchange Agreement is not adjustable based on the market price of our common stock, so the Exchange consideration at the Closing may have a greater or lesser value than at the time the Exchange Agreement was signed.

At the Closing, the issued and outstanding share capital of F-star will be exchanged for shares of our common stock based on the exchange ratio formula in the Exchange Agreement (the “Exchange Ratio”). The Exchange Ratio may be adjusted to the extent that (i) our expected net cash as of Closing is less than $15.0 million or greater than $17.0 million, (ii) F-star does not raise at least $25.0 million in a private placement of ordinary shares of F-star to occur prior to the Closing (the “Pre-Closing Financing”), and (iii) to account for the actual proceeds raised in the Pre-Closing Financing. Should the Closing occur after September 30, 2020, the $15.0 million and $17.0 million thresholds will each be reduced by $250,000 on October 30, 2020 and on the last day of each 30-day period thereafter until the Closing occurs. These and other adjustments to the Exchange Ratio are described further in the Exchange Agreement. Immediately following the Closing and assuming an Exchange Ratio of 0.5338 (which assumes both that our valuation will not be adjusted as a result of the expected net cash at Closing and that F-star raises $25.0 million in the Pre-Closing Financing), Spring Bank equity holders and the holders of F-star’s share capital are expected to own approximately 38.8% and 61.2%, respectively, of the outstanding capital stock of the combined company. However, as a result of these and other adjustments described in the Exchange Agreement, either the Spring Bank equity holders or the F-star equity holders could own more or less of the combined company than currently expected.

Any changes in the market price of our common stock before the completion of the Exchange will not affect the number of shares of our common stock issuable to the F-star equity holders pursuant to the Exchange Agreement. Therefore, if before the completion of the Exchange, the market price of our common stock declines from the market priceAnnual Report on the date of the Exchange Agreement, then the F-star equity holders could receive Exchange consideration with substantially lower value than the value of the Exchange consideration on the date of the Exchange Agreement. Similarly, if before the completion of the Exchange, the market price of our common stock increases from the market price of our common stock on the date of the Exchange Agreement, then F-star’s equity holders could receive Exchange consideration with substantially greater value than the value of the Exchange consideration on the date of the Exchange Agreement. Because the Exchange Ratio does not adjust as a result of changes in the market price of our common stock, for each one percentage point change in the market price of our common stock, there is a corresponding one percentage point rise or decline, respectively, in the value of the total Exchange consideration payable to the F –star equity holders pursuant to the Exchange Agreement.


Form

10-K

Our stockholders may not receive any payment on the CVRs and the CVRs may otherwise expire valueless.

At the Closing, Spring Bank, F-star, a representative of the Spring Bank stockholders prior to the Closing, and Computershare Trust Company N.A., as the Rights Agent, will enter into a STING Agonist Contingent Value Rights Agreement (the “STING Agonist CVR Agreement”) and a STING Antagonist Contingent Value Rights Agreement (the “STING Antagonist CVR Agreement” and, togetherfiled with the STING Agonist CVR Agreement, the “CVR Agreements). Each share of our common stock held by our stockholders as of a record date prior to the Closing will receive a dividend of (i) one contingent value right entitling these holders to receive payments in connection with certain transactions involving Spring Bank’s proprietary STING agonist compound (“STING Agonist CVR”), and (ii) one contingent value right entitling these holders to receive payments in connection with the execution of a potential development agreement and certain other transactions involving Spring Bank’s proprietary STING antagonist compound (the “STING Antagonist CVR” and, together with the STING Agonist CVR, the “CVRs”).

The right of our stockholders to receive any future paymentSEC on or to derive any value from the CVRs will be contingent solely upon the achievement of the events specified in the CVR Agreements within the time periods specified in the CVR Agreements and the consideration received being greater than any amounts permitted to be retained or deducted by the combined company under the CVR Agreements. The combined company may not be able to successfully achieve the development of Spring Bank’s STING Agonist or Antagonist compounds in a manner or within a time period that would generate payment pursuant to the CVR Agreements. If these payment triggering events are not achieved for any reason within the time periods specified in the CVR Agreements or the consideration received for these events is not greater than the amounts permitted to be retained or deducted by the combined company, no payments will be made under the CVRs, and the CVRs will expire valueless.

Furthermore, the CVRs will be unsecured obligations of the combined company and all payments under the CVRs, all other obligations under the CVR Agreement and the CVRs and any rights or other related claims will be subordinated in right of payment to the prior payment in full of all current or future senior obligations of the combined company. Finally, the U.S. federal income tax treatment of the CVRs is unclear. There is no legal authority directly addressing the U.S. federal income tax treatment of the receipt of, and payments on, the CVRs, and there can be no assurance that the Internal Revenue Service would not assert, or that a court would not sustain, a position that could result in adverse U.S. federal income tax consequences to holders of the CVRs.

Failure to complete the Exchange may result in either Spring Bank or F-star paying a termination fee to the other party and could significantly harm the market price of our common stock and negatively affect our future business and operations.

If the Exchange is not completed and the Exchange Agreement is terminated under certain circumstances, the terminating party may be required to pay the other party a termination fee of $2 million. In addition, under certain conditions, we may be required to reimburse F-star for up to $750,000 of F-star’s expenses. Even if a termination fee or expenses of the other party are not payable in connection with a termination of the Exchange Agreement, we will have incurred significant fees and expenses, which must be paid whether or not the Exchange is completed. Further, if the Exchange is not completed, it could significantly harm the market price of our common stock.

In addition, if the Exchange Agreement is terminated and our Board of Directors determines to seek another business combination or strategic transaction, there can be no assurance that we will be able to find a partner and close an alternative transaction on terms that are as favorable or more favorable than the terms set forth in the Exchange Agreement.

The Exchange may be completed even though certain events occur prior to the Closing that materially and adversely affect Spring Bank or F-star.

The Exchange Agreement provides that either Spring Bank or F-star can refuse to complete the Exchange if there is a material adverse change affecting the other party between the date of the Exchange Agreement and the Closing. However, certain types of changes do not permit either party to refuse to complete the Exchange, even if this change could have a material adverse effect on Spring Bank or F-star, including:

natural disasters, acts of terrorism, sabotage, military action or war or any escalation or worsening of military actions or wars, or any viruses, pandemics, epidemic or other outbreaks of illness or public health events, or any spread or worsening of these events (including worsening of the COVID-19 pandemic), or any other circumstance that may be considered a force majeure event;

certain changes in, or any compliance with or action taken for the purpose of complying with, applicable laws or GAAP, International Financial Reporting Standards or related interpretations provided these matters do not disproportionately affect Spring Bank or F-star, respectively;

actions taken by Spring Bank as reasonably necessary to comply with the Exchange Agreement or as otherwise permitted by the Exchange Agreement;

a government authority’s rejection or non-acceptance of intellectual property filings and applications;

regulatory action or the announcement of regulatory action regarding potentially competitive products or product candidates; and

stockholder litigation arising from or relating to the Exchange Agreement or the Exchange.

If adverse changes occur and Spring Bank and F-star still complete the Exchange, the market price of the combined company’s common stock may suffer. This in turn may reduce the value of the Exchange to the stockholders of Spring Bank, F-star or both.

Some of our officers and directors have interests in the Exchange that are different from our stockholders and that may influence them to support or approve the Exchange without regard to the interests of our stockholders.

Certain of our officers and directors participate in arrangements that provide them with interests in the Exchange that are different from the interests of our stockholders. These interests relate to or arise from, among other things, (i) severance payments to which certain of our executive officers will be entitled following completion of the Exchange as a result of termination of employment under certain circumstances, (ii) the accelerated vesting of certain of the equity awards held by our executive officers and directors in connection with the completion of the Exchange, and (iii) the fact that certain of our current directors will continue as directors of the combined company after the Closing, each of which could influence them to support the Exchange.

The market price of our common stock following the Exchange may decline as a result of the Exchange.

The market price of our common stock may decline as a result of the Exchange for a number of reasons, including if:

investors react negatively to the prospects of the combined company’s product candidates, business and financial condition following the Exchange;

the effect of the Exchange on the combined company's business and prospects is not consistent with the expectations of financial or industry analysts; or

the combined company does not achieve the perceived benefits of the Exchange as rapidly or to the extent anticipated by financial or industry analysts.

Our stockholders may not realize a benefit from the Exchange commensurate with the ownership dilution they will experience in connection with the Exchange.

If the combined company is unable to realize the strategic and financial benefits currently anticipated from the Exchange, our stockholders will have experiencedsubstantial dilution of their ownership interests in our company without receiving the expected commensurate benefit, or only receiving part of the commensurate benefit to the extent the combined company is able to realize only part of the expected strategic and financial benefits currently anticipated from the Exchange.



The combined company will need to raise additional capital by issuing securities or debt or through licensing or other strategic arrangements, which may cause dilution to the combined company’s stockholders or restrict the combined company’s operations or impact its proprietary rights.

The combined company may be required to raise additional funds sooner than currently planned. If either or both of Spring Bank or F-star hold less cash at the time of the Closing than the parties currently expect, the combined company will need to raise additional capital sooner than expected. The combined company will also generally need to raise substantial additional capital to support its planned operations. Additional financing may not be available to the combined company when it needs it or may not be available on favorable terms. In addition, the combined company’s ability to obtain future funding when needed may be particularly challenging in light of the uncertainties and circumstances regarding the COVID-19 pandemic. To the extent that the combined company raises additional capital by issuing equity securities, this issuance may cause significant dilution to the combined company’s stockholders’ ownership. The terms of any new equity securities may have preferences over the combined company’s common stock. Any debt financing the combined company enters into may involve covenants that restrict its operations. These restrictive covenants may include limitations on additional borrowing and specific restrictions on the use of the combined company’s assets, as well as prohibitions on its ability to create liens, pay dividends, redeem its stock or make investments. In addition, if the combined company raises additional funds through licensing, partnering or other strategic arrangements, it may be necessary to relinquish rights to some of the combined company’s technologies or product candidates and proprietary rights, or grant licenses on terms that are not favorable to the combined company.

During the pendency of the Exchange, we may not be able to enter into a business combination with another party at a favorable price because of restrictions in the Exchange Agreement, which could adversely affect our business.

Subject to certain exceptions, covenants in the Exchange Agreement impede the ability of Spring Bank to make acquisitions or to complete other transactions that are not in the ordinary course of business pending completion of the Exchange. As a result, if the Exchange is not completed, we may be at a disadvantage to our competitors during this period. In addition, while the Exchange Agreement is in effect, we are generally prohibited from soliciting, initiating, encouraging or entering into certain extraordinary transactions, such as a merger, sale of assets, or other business combination outside the ordinary course of business with any third party, subject to certain exceptions relating to fiduciary duties.

The pendency of the Exchange could have an adverse effect on the trading price of our common stock and our business, financial condition and prospects.

The pendency of the Exchange could disrupt our business in many ways, including:

the attention of our management and employees may be directed toward the completion of the Exchange and related matters and may be diverted from our day-to-day business operations; and

third parties may seek to terminate or renegotiate their relationships with us as a result of the Exchange, whether pursuant to the terms of their existing agreements with us or otherwise.

Should they occur, any of these matters could adversely affect the trading price of our common stock or harm our business, financial condition and prospects.

We are substantially dependent on our employees to facilitate the consummation of the Exchange.

Our ability to successfully complete the Exchange depends in large part on our ability to retain certain personnel. Despite our efforts to retain these employees, one or more may terminate their employment with us on short notice. The loss of the services of certain employees could potentially harm our ability to consummate the Exchange, to run our day-to-day business operations, as well as to fulfill our reporting obligations as a public company.

Litigation relating to the Exchange could require us to incur significant costs and suffer management distraction, and could delay or enjoin the Exchange.

We could be subject to demands or litigation related to the Exchange, whether or not the Exchange is consummated. Such actions may create uncertainty relating to the Exchange, or delay or enjoin the Exchange, result in substantial costs to us and divert management time and resources.
