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

The following discussion of our financial condition and results of operations should be read together with our unaudited condensed financial statements and related notes and other financial information included elsewhere in this Quarterly Report, as well as our audited financial statements and notes thereto and the related Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020 filed with the Securities and Exchange Commission (“SEC”) on March 22, 2021 (“2020 Annual Report”). As used in this Quarterly Report, references to the “Company,” “we,” “us,” “our,” or similar terms refer to Outset Medical, Inc.

In addition to historical financial information, this discussion and other parts of this report contain forward-looking statements within the meaning of the federal securities laws. All statements other than statements of historical fact contained in this Quarterly Report are forward-looking statements. TheThe forward-looking statements in this report are only predictions and are based largely on our current expectations and projections about future events and financial trends that we believe may affect our business, financial condition and results of operations. These forward-looking statements are subject to a number of known and unknown risks, uncertainties and assumptions that may cause our actual results, performance or achievements to be materially different from those expressed or implied by the forward-looking statements.

Our technology is designed to elevate the dialysis experience for patients, and help providers overcome traditional care delivery challenges. Requiring only an electrical outlet and tap water to operate, ~~Tablo~~the Tablo® Hemodialysis System frees patients and providers from the burdensome infrastructure required to operate traditional dialysis machines. The integration of water purification and on-demand dialysate production enables Tablo to serve as a dialysis clinic on wheels and allows providers to standardize to a single technology platform from the hospital to the home. Tablo is also intelligent and connected, with automated documentation and the ability to integrate with electronic medical record reporting, along with streamlined remote machine management designed to maximize device uptime. We have generated meaningful evidence to demonstrate that providers can realize significant operational efficiencies, including reducing the cost of their dialysis programs by up to 80% in the intensive care unit. In addition, Tablo has been shown to deliver robust clinical care. In studies we have conducted, patients have reported experiencing fewer symptoms and better quality sleep while on Tablo. We believe Tablo empowers patients, who have traditionally been passive recipients of care, to regain agency and ownership of their treatment. Tablo is cleared by the U.S. Food and Drug Administration (“FDA”) for use in the hospital, clinic or home setting.

We designed Tablo from the ground up to be a single enterprise solution that can be utilized across the continuum of care, allowing dialysis to be delivered anytime, anywhere and by anyone. Tablo is comprised of a compact console with integrated water purification, on-demand dialysate production and a simple-to-use touchscreen interface. With Tablo, we are bringing data to dialysis. Tablo is built to live in a connected setting with cloud-based system monitoring, patient analytics, remote treatment monitoring and clinical recordkeeping and the ability to activate new capabilities and enhancements through wireless software updates. Tablo’s data analytics and connectivity also enable predictive and preventative maintenance designed to maximize machine uptime. Unlike existing hemodialysis machines, which have limited clinical versatility across care settings and are generally burdened by specialized and expensive infrastructure, Tablo is a single enterprise dialysis solution that can be seamlessly utilized across different care settings and for multiple clinical needs.

Driving adoption of Tablo in the acute care setting has been our primary focus to date. We have invested in growing our economic and clinical evidence, built a veteran sales and clinical support team with significant expertise, and implemented a comprehensive training and customer experience program. Our experience in the acute market has demonstrated Tablo’s clinical flexibility and operational versatility, while also delivering meaningful cost savings to the providers. We plan to continue leveraging our commercial infrastructure to broaden our installed base in the acute care market as well as driving utilization and fleet expansion with our existing customers. While the COVID-19 pandemic has presented opportunities to demonstrate the real-world benefits of Tablo over traditional machines, we believe these benefits, in addition to the other advantages of Tablo, are continuing to drive customer purchasing decisions.

Tablo is also well suited for home-based dialysis. Tablo was cleared by the FDA for use in patients with acute and/or chronic renal failure in September 2014. Subsequently, on March 31, 2020, Tablo was cleared by the FDA for patient use in the home. Our ability to reduce training time, patient dropout, preparation and set up time, and the total treatment time required to deliver dialysis in the home can drive efficiency and economic improvements to the home care model. In our home investigational device exemption (“IDE”) trial, patients reported specific quality of life improvements compared to their experience on the incumbent home dialysis machine. To penetrate and grow this market successfully, we are focused on refining our home distribution, logistics and support systems to help ensure they are ready for rapid scale. We are also working with providers, patients and payors to increase awareness

and adoption of transitional care units (“TCUs”) as a bridge to home based therapy. To demonstrate the cost advantages of Tablo in the home setting, we will also be collecting additional patient clinical experience and outcomes data.

We sell our ~~solution~~solutions through our direct sales organization, which covers most major metropolitan markets in the United States. As of ~~June~~September 30, 2021, our sales organization is comprised of 2934 capital sales team members, responsible for generating new customer demand for Tablo, and 7077 clinical sales team members responsible for driving utilization and fleet expansion of Tablo consoles at existing customer sites. In addition, our field service team comprised of 7888 members provides maintenance services and product support to Tablo customers. The same sales organization and field service team drive Tablo penetration in both the acute and home markets. We believe the ability to leverage one team to serve both markets will result in significant productivity and cost optimization as we continue to scale our business.

We are continuing to execute a well-defined strategy designed to expand gross margins. First, we have successfully begun production at our own console manufacturing facility. Second, we are adding a second-source contract manufacturer for our cartridges to help gain higher efficiency and lower material and logistics cost. Third, we will continue to drive scale across our console platform to leverage our supply base and help improve our manufacturing efficiency. Fourth, we will continue to utilize our cloud-based data system, as well as enhanced product performance, to help drive down the cost of service.

We generate revenue primarily from the initial sale of Tablo consoles, and recurring sales of per-treatment consumables, including the Tablo cartridge, which generates significant total revenue over the life of the console. We generate additional revenue via annual service contracts and shipping and handling charged to customers. Our total revenue was ~~$25.2~~$26.3 million and ~~$11.7~~$13.8 million for the three months ~~ended June~~ended September 30, 2021 and 2020, ~~respectively,~~respectively, and ~~$48.1~~$74.5 million and ~~$18.9~~$32.7 million for the ~~six~~nine months ended ~~June~~September 30, 2021 and 2020, respectively.

For the three months ended ~~June~~September 30, 2021 and 2020, we incurred net losses of ~~$30.2~~$30.5 million and ~~$26.5~~$42.3 million, respectively, and for the ~~six~~nine months ended ~~June~~September 30, 2021 and 2020, we incurred net losses of ~~$60.2~~$90.7 million and ~~$47.2~~$89.4 million, respectively. As of ~~June~~September 30, 2021, we had an accumulated deficit of ~~$554.3~~$584.8 million.

On September 17, 2020, we completed our initial public offering (“IPO”), in which we sold 10,293,777 shares of common stock (which included 1,342,666 shares that were offered and sold pursuant to the full exercise of the IPO underwriters’ option to purchase additional shares in connection with the IPO) at a price to the public of $27.00 per share. We received aggregate net proceeds of approximately $254.8 million after deducting offering costs, underwriting discounts and commissions of approximately $23.1 million. Upon the closing of the IPO, all of our outstanding redeemable convertible preferred stock automatically converted into shares of common stock.

On April 13, 2021, we completed a follow-on public offering and sold 2,945,864 shares of our common stock (which included 445,864 shares that were offered and sold pursuant to the full exercise of the underwriters’ option to purchase additional shares) at a price to the public of $53.50 per share. We received aggregate net proceeds of approximately $149.1 million after deducting offering costs, underwriting discounts and commissions of $8.5 million.

We believe that the COVID-19 pandemic has highlighted the limitations of traditional machines and the benefits of Tablo, driving an increase in demand for Tablo during 2020. We also believe the advantages of Tablo highlighted by the pandemic are now embedded as one of the many factors driving our customers’ purchasing decisions and do not expect to experience significant revenue driven solely by COVID-19 in future periods. However, the duration and extent of the COVID-19 pandemic remain uncertain, particularly in light of ongoing vaccination efforts and emerging variant strains of the virus, and we cannot predict with certainty the ultimate impact of the COVID-19 pandemic and related containment measures on our business.

In order to operate in a safe manner, we continue to monitor and follow the latest health and safety guidelines of the U.S. Centers for Disease Control and Prevention, Occupational Safety and Health Administration, and local and state public health departments where we operate. These guidelines continue to change in light of local circumstances related to vaccine availability, population vaccination rates and emerging variant strains of the virus (including the Delta variant which appears to be highly transmissible). For employees working on-site, we continue to follow masking protocols consistent with evolving health and safety guidelines, facilitate social distancing and practice increased sanitizing standards. We have strongly encouraged all of our employees to get vaccinated, and during the third quarter of 2021, adopted a policy requiring our customer-facing and on-site employees to be fully vaccinated by October 2021, subject to medical or religious exemptions. Additionally, we continue to provide vaccination site information and COVID-19 testing at our facilities. We ~~also~~are actively ~~support~~supporting remote work ~~arrangements. In addition,~~arrangements, while planning for a more structured return to office in late 2021 to increase productive collaboration while helping to ensure employee safety. Lastly, we have created a business continuity plan and incident management team to respond quickly and effectively to changes in order to offer customers uninterrupted products, services and support while safeguarding the best interest of employees, suppliers and stockholders.

Our business may also be impacted by an escalation or a continuation of the COVID-19 pandemic. While the operations at our contract manufacturing partners’ facilities and our outsourced business administration service provider, TACNA, for our facility in Tijuana, Mexico, have not yet experienced significant disruption as a result of the pandemic, the possibility that such disruption may

occur remains. Additionally, the COVID-19 pandemic has disrupted the operations of certain of our third-party suppliers, resulting in increased lead-times, higher component costs and lower allocations for our purchase of some components (including certain critical components) and, in certain cases, requiring us to procure materials from alternative sources or incur higher logistical expenses. We have worked closely with our manufacturing partners and suppliers to enable us to source key components and maintain appropriate

inventory levels to meet customer demand, and have not experienced material disruptions in our supply chain to date.

Additionally, surges and shifts in consumer demand as the economy reopens, further exacerbated by COVID-19 outbreaks and protocols, have strained the global freight network and placed significant stress on air, ocean and ground freight carriers. This has resulted in labor shortages, container and chassis shortages, reduced carrier capacity, carrier delays and longer lead times, shipment receiving and unloading backlogs at many U.S. ports, and escalating freight costs. These supply chain disruptions have escalated during the fourth quarter of 2021, and we are facing increased supply chain constraints, notably with the transportation of Tablo cartridges from our contract manufacturing partner in Southeast Asia. As a result, we have faced, and may continue to face, increased transportation and related costs associated with delivering adequate supply of Tablo treatments to our customers. Continued escalation of these supply chain disruptions and a sustained rise in freight costs could negatively impact our ability to meet customer demand on a timely basis, result in customer dissatisfaction and adversely impact our operating margins and results of operation.

How long the pandemic, and measures intended to contain the spread of COVID-19, will continue remains uncertain and depends on ongoing developments, including but not limited to any resurgences of the virus including emerging variant strains such as the Delta variant, federal, state and local government actions taken in response, and continued availability, effectiveness and public acceptance of COVID-19 vaccines. Additionally, the duration and severity of disruptions in the global supply chain, largely driven by high demand as the economy reopens and the ongoing impact of the pandemic, also remain uncertain and depend on various factors, including the effectiveness of recent government actions intended to mitigate these disruptions. As a result, we cannot predict what effect COVID-19, ~~and~~ the associated containment measures and the related supply chain disruptions will ultimately have on our business and results of operations, or on our suppliers and vendors, in particular for any of our suppliers and vendors that may not qualify as essential businesses and suffer more significant or lengthier disruptions to their business operations. There is no assurance that we will not experience more significant disruptions in our supply chain in the future, particularly if the operations of our contract manufacturing partners, our critical ~~single source~~single-source component providers, or the facility we operate in Tijuana, Mexico in collaboration with TACNA, are more severely impacted by the pandemic and associated containment measures.

~~Interest income and other income, net decreased by $0.3 million, or 48% for the six months ended June 30, 2021 as compared to the six months ended June~~September 30, 2020. The decrease was primarily due to a $5.6 million net decrease in compensation and personnel costs, which includes a $7.2 million decrease in stock-based compensation expense due to the one-time cumulative expense related to stock options with performance and market-based vesting conditions in 2020 which offset by a $1.6 million increase compensation, and a $0.7 million decrease in outside services costs. The decrease was partially offset by a $0.6 million increase in insurance costs and a $0.1 million increase in allocated costs for facilities and information technology to support the general expansion of our operations.

General and administrative expenses increased by $5.1 million, or 24% for the nine months ended September 30, 2021 as compared to the nine months ended September 30, 2020. The increase was primarily due to a $2.4 million increase in insurance costs, a $1.2 million net increase in compensation and personnel costs, which includes a $4.2 million increase in compensation offset by a $3.0 million decrease in stock-based compensation expense due to the one-time cumulative expense related to stock options with performance and market-based vesting conditions in 2020, a $0.8 million increase in professional and consulting services and a $0.7 million increase in allocated costs for facilities and information technology to support the general expansion of our operations.

Interest income and other income (expense), net increased by $0.1 million for the three months ended September 30, 2021 as compared to the three months ended September 30, 2020. This increase was primarily due to a higher average balance in money market funds and short-term investment securities in the three months ended September 30, 2021.

Interest income and other income (expense), net decreased by $0.1 million, or 28% for the nine months ended September 30, 2021 as compared to the nine months ended September 30, 2020. The decrease was primarily due to a $0.4 million decrease in interest income driven by lower interest rates ~~in the first half of~~during 2021. This decrease was partially offset by a $0.3 million value added taxes refund primarily related to startup costs in our new manufacturing facility received during 2021.

Interest expense slightly increased for the ~~first half~~three months ended September 30, 2021 as compared to the three months ended September 30, 2020 due to accretion of ~~2021.~~the SVB Term Loan.

Interest expense decreased for the ~~three and six~~nine months ended ~~June~~September 30, 2021 as compared to the ~~three and six~~nine months ended ~~June~~September 30, 2020. The decrease was driven primarily by a lower interest rate under the SVB Term Loan as compared to the rate under the Perceptive Term Loan, which we voluntarily repaid in July 2020.

The change in the fair value of redeemable convertible preferred stock warrant liability was driven by the changes in assumptions used to value the warrant liability. Upon the closing of our IPO in September 2020, all ~~shares~~ of our outstanding redeemable convertible preferred stock warrants were either exercised into common stock or automatically converted into warrants to purchase common stock. Accordingly, we have ceased to incur the change in the fair value of redeemable convertible preferred stock warrant liability as the entire redeemable convertible preferred stock warrant liability was reclassified to additional paid-in capital.

The loss on extinguishment of term loan of $1.6 million was recognized for the repayment of the Perceptive Team Loan in July 2020, which included early repayment and exit fees.

As of ~~June~~September 30, 2021, ~~the Company~~we had cash, cash equivalents and short-term investments of ~~$396.2~~$373.0 million, which are available to fund future operations, and restricted cash of $33.3 million, for a total cash, cash equivalents, restricted cash and short-term investments balance of ~~$429.5~~$406.4 million.

Since our inception, we have incurred net losses and negative cash flows from operations. To date, we have financed our operations and capital expenditures primarily through sales of redeemable convertible preferred stock and common stock, revenue from sales and issuances of debt. In September 2020, we completed our IPO for aggregate net proceeds of approximately $254.8 million (inclusive of the full exercise of the underwriters’ option to purchase additional shares), net of offering costs, underwriter discounts and commissions of $23.1 million. In April 2021, we completed a follow-on public offering for aggregate net proceeds of approximately ~~$149.1~~$149.1 million,, after deducting offering costs, underwriting discounts and commissions of $8.5 million.

We expect to continue to incur significant expenses for the foreseeable future and to incur operating losses in the near term while we make investments to support our anticipated growth. We may raise additional capital through the issuance of additional equity financing, debt financings or other sources. If this financing is not available to us at adequate levels or on acceptable terms, we may need to reevaluate our operating plans. If we do raise additional capital through public or private equity offerings, the ownership interest of our existing stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect our existing stockholders’ rights. If we raise additional capital through debt financing, we may be subject to covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring

dividends. We believe that our existing cash, cash equivalents and short-term investments, and cash generated from sales of our products, will be sufficient to meet our anticipated needs for at least the next 12 months from the date of this Quarterly Report.

The following table summarizes the cash flows for each of the periods indicated (in thousands):

The net cash used in operating activities of ~~$69.5~~$97.6 million for the ~~six~~nine months ended ~~June~~September 30, 2021 was due to a net loss of ~~$60.2~~$90.7 million and a net cash outflow from the change in our operating assets and liabilities of ~~$23.1~~$26.5 million, which were partially offset by adjustments for stock-based compensation expense of ~~$9.8~~$12.7 million, depreciation and amortization of ~~$2.6 million, non-cash lease expense of $0.5~~$3.9 million, accretion of discount on investments of ~~$0.4~~$1.2 million, non-cash lease expense of $0.8 million, provision for inventories of $0.8 million, and non-cash interest expense of ~~$0.3 million, and provision for inventories of $0.3~~$0.4 million. The net cash outflow from operating assets and liabilities was primarily due to an increase in inventories of ~~$12.1~~$17.9 million due to the timing of inventory purchases including advance purchases of inventory due to the ~~transition to our own manufacturing facility,~~ anticipated demand and to mitigate supply chaindisruptions, which partially related to COVID-19,, an increase in accounts receivable of ~~$9.9~~$12.8 million due to timing of collections, a ~~net~~ decrease in account payable ~~accrued expenses and other current liabilities~~ of ~~$1.0~~$2.1 million due to timing of vendor payments, and a decrease in ~~accrued payroll and related benefits of $1.5 million, and a decrease in~~ operating lease liabilities of ~~$0.4~~$0.6 million. The net cash outflow from operating assets and liabilities was partially offset by an increase in accrued expenses and other current liabilities of $3.5 million, an increase in deferred revenue of ~~$1.1~~$1.6 million due to the growth of our business, an increase in accrued payroll and related benefits of $0.9 million, a decrease in prepaid expenses and other assets of ~~$0.6~~$0.7 million, and an increase in accrued warranty liability of ~~$0.2~~$0.3 million.

~~The net~~Net cash used in operating activities of $73.2 million for the ~~six~~nine months ended ~~June~~September 30, 2020 was ~~$44.1 million, attributable~~due to a net loss of ~~$47.2~~$89.4 million and a net change in our net operating assets and liabilities of ~~$0.3~~$3.2 million, partially offset by ~~non-cash charges of $3.4 million. Non-cash charges primarily consisted of $1.3 million in~~adjustments for stock-based compensation ~~$0.7~~of $15.2 million, inloss on extinguishment of term loan of $1.6 million, depreciation and amortization of $1.2 million, non-cash interest expense of $0.5 million, ~~in the~~non-cash lease expense of $0.4 million, provision for inventories of $0.4 million, and change in ~~the~~ fair value of ~~the~~ redeemable convertible preferred stock warrant liability ~~$0.4 million in non-cash interest expense, $0.2 million in provision for inventory and~~of $0.1 ~~million in no-cash lease expense.~~million. The ~~change in our~~ net cash outflow from operating assets and liabilities was primarily due to ~~a $3.4 million increase in accounts receivable and a $2.0 million~~an increase in inventories of $9.2 million due to ~~growth in our business, a $0.7 million decrease in accounts payable~~the timing of inventory purchases including advance purchases of inventory due to ~~timing of payments and a $0.6 million~~anticipated demand, an increase in prepaid expenses and other ~~assets. These changes were~~assets of $5.4 million, and an increase in accounts receivable of $3.2 million due to timing of collections. The net cash outflow from operating assets and liabilities was partially offset by ~~a $2.5 million~~an increase in accrued expenses and other current liabilities ~~due to timing~~ of ~~payments, a $2.2~~$5.1 million ~~increase in deferred revenue mainly due to~~consistent with the growth of our business, ~~a $1.1 million~~an increase in accrued payroll and related benefits of $3.9 million due to an increase in headcount, an increase in deferred revenue of $3.7 million, and ~~a $0.6 million~~an increase in accrued warranty ~~liability.~~liability of $1.6 million and an increase in accounts payable of $0.4 million due to timing of vendor payments.

The net cash used in investing activities of ~~$104.3~~$126.1 million for the ~~six~~nine months ended ~~June~~September 30, 2021 was due primarily to the purchases of investment securities of ~~$122.4~~$148.1 million and the purchases of property and equipment of ~~$1.8~~$2.3 million, partially offset by the sales and maturities of investment securities of ~~$19.9~~$24.3 million.

~~The net~~Net cash ~~provided by~~used in investing activities of $6.4 million for the ~~six~~nine months ended ~~June~~September 30, 2020 was ~~$25.5 million and related~~due primarily to the ~~sales~~purchases of short-term investments of $32.9 million and ~~maturities of investment securities of $30.5 million, partially offset by~~ the purchases of property and equipment of ~~$5.0~~$6.4 million, partially offset by the sales and maturities of short-term investments of $32.9 million.

The net cash provided by financing activities of ~~$153.0~~$159.2 million for the ~~six~~nine months ended ~~June~~September 30, 2021 was due primarily to the net proceeds of $149.1 million from the issuance of our common stock upon the follow-on offering and the proceeds of ~~$3.9~~$10.1 million from employee exercises of stock options and employee stock purchase plan purchases.

~~The net~~Net cash provided by financing activities of $386.6 million for the ~~six~~nine months ended ~~June~~September 30, 2020 was due primarily to the net proceeds of $255.7 million from the issuance of our common stock in our IPO, net of issuance costs paid to date, the net proceeds of $126.8 million from the issuance of our Series E redeemable convertible preferred ~~stock.~~stock, the net proceeds of $29.6 million from borrowings on the SVB Loan and Security Agreement, proceeds of $4.3 million from the exercise of the Series C redeemable

convertible preferred stock warrants, and proceeds of $1.1 million from the issuance of common stock from exercises of stock options, partially offset by the cash outflow of $31.0 million in repayment of Perceptive Loan which included early prepayment and exit fees.

During the three and ~~six~~nine months ended ~~June~~September 30, 2021, there have been no material changes to our contractual obligations from those disclosed in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our 2020 Annual Report.

During the periods presented, we did not have, nor do we currently have, any off-balance sheet arrangements, as defined in the rules and regulations of the SEC.

Management’s discussion and analysis of the financial condition and results of operations is based on the financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported revenues and expenses incurred during the reporting periods. The estimates are based on historical experience and on various other factors that are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

There have been no significant changes in our critical accounting policies and estimates as compared to the critical accounting policies and estimates disclosed in the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our 2020 Annual Report. For additional information, please refer to Note 2 to our unaudited condensed financial statements in this Quarterly Report.

We are an emerging growth company, as defined in theJumpstart Our Business Startups Act (“JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. We elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that we (i) are no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, our financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates.

Because (i) the aggregate worldwide market value of our voting common stock held by non-affiliates (or "public float") exceeded $700 million on June 30, 2021, (ii) we will have been subject to the reporting requirements of Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (“Exchange Act”) for at least twelve calendar months, (iii) we have previously filed an annual report under Section 13(a) or 15(d) of the Exchange Act and (iv) we are not eligible for smaller reporting company status because we exceed the public float and revenue threshold for such status, we will qualify as a "large accelerated filer" under Rule 12b-2 of the Exchange Act as of the end of the current fiscal year. As a large accelerated filer, we will no longer qualify as an emerging growth company.

See Note 2 to our unaudited condensed financial statements included elsewhere in this Quarterly Report for more information.

Our cash, cash equivalents, restricted cash and short-term investments are held in bank deposits, money market funds, U.S. Treasury and debt securities. Such interest-earning instruments carry a degree of interest rate risk. The goals of our investment policy are liquidity and capital preservation; we do not enter into investments for trading or speculative purposes and have not used any derivative financial instruments to manage our interest rate exposure. We believe that we do not have any material exposure to changes in the fair value of these assets as a result of changes in interest rates due to the relative short-term nature of our cash, cash equivalents and short-term investments.

As of ~~June~~September 30, 2021, we had $30.0 million in variable rate debt outstanding. The SVB Term Loan matures on November 1, 2025, with interest-only monthly payments until June 2023. The term loan accrues interest at a rate per annum equal to the greater of (A) one-half of one percent (0.50%) above the Prime Rate as reported in the Wall Street Journal then in effect (which shall not be less than zero) and (B) three and three-quarters of one percent (3.75%). An immediate 100 basis point change in the prime rate would not have a material impact on our debt-related obligations, financial position or results of operations.

Our expenses are generally denominated in U.S. dollars. However, as certain of our Mexico-based manufacturing operations incur costs that are denominated in Mexican Pesos (“MXN”), we are exposed to the risk of currency fluctuations between the U.S. dollar and MXN. To date, foreign currency transaction gains and losses have not been material to our financial statements.

Unfavorable changes in foreign exchange rates versus the U.S. dollar could increase our product costs, thus reducing our gross profit. We have not engaged in the hedging of foreign currency transactions to date, although we may choose to do so in the future. We do not believe that an immediate 10% increase or decrease in the relative value of the U.S. dollar to other currencies would have a material effect on our operating results or financial condition.

Our management, with the participation and supervision of our Chief Executive Officer and Chief Financial Officer, have evaluated the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15(e) and 15d-15(e) under the Exchange Act as of the end of the period covered by this Quarterly Report. Our disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and our Chief Financial Officer, to allow timely decisions regarding required disclosures. Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objective and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective at a reasonable assurance level as of the period covered by this Quarterly Report.

There were no changes in our internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

From time to time we may become involved in legal proceedings or investigations, which could have an adverse impact on our reputation, business and financial condition and divert the attention of our management from the operation of our business. We are not presently a party to any legal proceedings that, if determined adversely to us, would individually or taken together have a material adverse effect on our business, results of operations, financial condition or cash flows.

You should carefully consider the risk factors discussed in Part I, “Item 1A. Risk Factors” in our 2020 Annual Report, as updated by the risk factors discussed in Part II, “Item 1A. Risk Factors” in our Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2021 (“Q1 2021 Quarterly Report”), which could materially affect our business, financial position, or future results of operations. There have been no material changes to the risk factors described in our 2020 Annual Report, as updated by our Q1 2021 Quarterly ~~Report.~~ Report, except as set forth below. The risks described in our 2020 Annual Report and our Q1 2021 Quarterly Report as updated below are not the only risks that we face. Additional risks and uncertainties not precisely known to us, or that we currently deem to be immaterial, may also arise and materially impact our business. If any of these risks occur, our business, results of operations and financial condition could be materially and adversely affected and the trading price of our common stock could decline.

We depend upon third-party suppliers, including contract manufacturers and single-source suppliers, making us vulnerable to supply problems and price fluctuations.

We rely on third-party suppliers, including in some instances single-source suppliers, to provide us with certain components of Tablo. The number of suppliers feeding into Tablo console production is in excess of 250 worldwide. We consider approximately 9% of these suppliers, located in the United States, Europe and China, as critical providers of components such as pumps, motors, valves and PCBA boards. While we are undertaking a second source qualification process for the majority of these critical components, we may not ultimately be successful in securing second sourcing for all of them.

In addition, we purchase supplies through purchase orders and do not have long-term supply agreements with, or guaranteed commitments from, our suppliers, including single-source suppliers. Moreover, at present, we rely on contract manufacturers for the production of the Tablo cartridge. Many of our suppliers and contract manufacturers are not obligated to perform services or supply products for any specific period, in any specific quantity or at any specific price, except as may be provided in a particular purchase order. We depend on our suppliers and contract manufacturers to provide us and our customers with materials in a timely manner that meet our and their quality, quantity and cost requirements. These suppliers and contract manufacturers may encounter problems during manufacturing for a variety of reasons, including as a result of public health crises such as the ongoing COVID-19 pandemic, labor disputes, work stoppages, damage or interruption from fires, severe weather or other natural disasters, vandalism, terrorism or other political hostilities, any of which could delay or impede their ability to meet our demand. These suppliers and contract manufacturers may cease producing the components we purchase from them or otherwise decide to cease doing business with us. Further, we maintain limited volumes of inventory from most of our suppliers and contract manufacturers. If we inaccurately forecast demand for finished goods, we may be unable to meet customer demand which could harm our competitive position and reputation. Further, if we fail to effectively manage our relationships with our suppliers and contract manufacturers, we may be required to change suppliers or contract manufacturers. While we believe replacement suppliers exist for all materials, components and services necessary to continue manufacturing our Tablo system, establishing additional or replacement suppliers for any of these materials, components or services could be time-consuming and expensive, may result in interruptions in our operations and product delivery, may affect the performance specifications of our Tablo system or could require that we modify Tablo’s design. Even if we are able to find replacement suppliers, we will be required to verify that the new supplier maintains facilities, procedures and operations that comply with our quality expectations and applicable regulatory requirements. Any of these events could require that we obtain a new regulatory authority approval before we implement the change, which could result in further delay and which may not be obtained at all. If our third-party suppliers fail to deliver the required commercial quantities of materials on a timely basis and at commercially reasonable prices, and we are unable to find one or more replacement suppliers capable of production at a substantially equivalent cost in substantially equivalent volumes and quality on a timely basis, the continued commercialization of our Tablo system, the supply of our products to customers and the development of any future products will be delayed, limited or prevented, which could have material adverse effect on our business, financial condition and results of operations.

For example, the COVID-19 pandemic has disrupted the operations of certain of our third-party suppliers, resulting in increased lead-times, higher component costs and lower allocations for our purchases of some components (including certain critical components) and, in certain cases, requiring us to procure materials from alternative sources or incur higher logistical expenses. We have worked closely with our manufacturing partners and suppliers to enable us to source key components and maintain appropriate inventory levels to meet customer demand, and have not experienced material disruptions in our supply chain to date. However, there is no assurance that we will not experience more significant disruptions in our supply chain in the future, particularly if the operations

of our contract manufacturing partners, any of our critical single-source component providers, or the facility we operate in Tijuana, Mexico in collaboration with our outsourced business administration service provider, Tacna, are more severely impacted by the pandemic and associated containment measures. If these contract manufacturers or suppliers experience disruptions as a result of the pandemic that impede their ability to meet our demand in a timely manner, we may be unable to find alternative sources of supply, be required to pay higher prices, or fail to meet customer demand, any of which would harm our business.

We have significant customer concentration, with a limited number of customers accounting for a substantial portion of our revenues.

For the nine months ended September 30, 2021, one customer and a federal health department customer accounted for 31% and 18% of our revenue, respectively. There are risks whenever a large percentage of total revenues are concentrated with a limited number of customers. It is not possible for us to predict the level of demand for Tablo that will be generated by any of these customers in the future. In addition, revenues from these larger customers may fluctuate from time to time based on these customers’ business needs and customer experience, the timing of which may be affected by market conditions or other factors outside of our control. Furthermore, because our business model consists of an upfront capital purchase by our customers, and relatively lower recurring revenue from future sales of consumables and services, revenues from these larger customers may not represent a substantial portion of our revenues in future periods. These customers could also potentially pressure us to reduce the prices we charge for Tablo, which could have an adverse effect on our margins and financial position and could negatively affect our revenues and results of operations. If any of our largest customers terminates its relationship with us, such termination could negatively affect our revenues and results of operations.

Performance issues, service interruptions or price increases by our shipping carriers and warehousing providers could adversely affect our business and harm our reputation and ability to provide our services on a timely basis.

Expedited, reliable shipping and secure warehousing are essential to our operations. We rely heavily on providers of transport services for reliable and secure point-to-point transport of our Tablo system to our customers and for tracking of these shipments, and from time to time require warehousing for our products. Should a carrier encounter delivery performance issues such as loss, damage or destruction of any systems, it would be costly to replace such systems in a timely manner and such occurrences may damage our reputation and lead to decreased demand for our Tablo system and increased cost and expense to our business. In addition, any significant increase in shipping or warehousing rates could adversely affect our operating margins and results of operations. For example, surges and shifts in consumer demand as the economy reopens, further exacerbated by COVID-19 outbreaks and protocols, have strained the global freight network and placed significant stress on air, ocean and freight ground carriers, resulting in increased freight costs. If freight costs continue to escalate and/or remain high for a sustained period of time, our operating margins and results of operations would be adversely impacted. Similarly, strikes, severe weather, natural disasters or other service interruptions affecting delivery or warehousing services we use would adversely affect our ability to process orders for our Tablo system on a timely basis.

The offer and sale of shares in our IPO was registered under the Securities Act pursuant to a registration statement on Form S-1 (File No.333-248225), which was declared effective by the SEC on September 17, 2020. The remainder of the information required by this item regarding the use of our IPO proceeds has been omitted pursuant to SEC rules because such information has not changed since our last periodic report was filed.
