The Company’s headquarters are located in San Jose, California.

Reverse Stock Split

In March 2025, the Company’s board of directors and shareholders approved a Certificate of Amendment to the Company’s Amended and Restated Certificate of Incorporation to effect a reverse split of shares of the Company’s common stock on a 15-for-one basis (the Reverse Stock Split), which became effective as of March 20, 2025. The number of authorized shares and the par values of the common stock and preferred stock were not adjusted as a result of the Reverse Stock Split. In connection with the Reverse Stock Split, the conversion ratio for the Company’s outstanding convertible preferred stock was proportionately adjusted such that the common stock issuable upon conversion of such preferred stock was decreased in proportion to the Reverse Stock Split. Also, any outstanding common stock warrants were adjusted such that the common stock issuable upon exercise of such warrants were decreased in proportion to the Reverse Stock Split. In addition, the number of shares of common stock available for issuance under the Company’s equity incentive plans and issuable upon the exercise of stock options, warrants and restricted stock units outstanding prior to the Reverse Stock Split were proportionately adjusted. No fractional shares were distributed as a result of the Reverse Stock Split and stockholders were entitled to a cash payment in lieu of fractional shares.

All common stock share and per share amounts and information presented herein have been retroactively adjusted to reflect the effect of the Reverse Stock Split for all periods presented.

Liquidity

Since inception, the Company has incurred net losses and negative cash flows from operations. During the six months ended June 30, 2025 and 2024, the Company incurred a net loss of $44.3 million and $74.4 million, respectively, and cash outflow from operating activities of $30.5 million and $79.2 million, respectively. As of June 30, 2025, the Company had an accumulated deficit of $1.1 billion.

As of June 30, 2025, the Company had cash, cash equivalents, restricted cash and short-term investments of $187.4 million. In January and March 2025, the Company sold 863,000 shares of its Series A Non-Voting Convertible Preferred Stock (Series A Convertible Preferred Stock) at a price of $200.00 per share in a private placement transaction (the Private Placement) for total gross proceeds of $172.7 million, before deducting placement agent fees and other offering expenses. Subsequently, 842,000 shares of Series A Convertible Preferred Stock were converted into 14,046,000 shares of the Company’s common stock. See Note 8 for further details.

In addition, in January 2025, the Company entered into a credit agreement and guaranty (the Perceptive Credit Agreement) with Perceptive Credit Holdings IV, LP, as administrative agent (Agent) and the lenders from time to time party thereto, which provided a $100 million 5-year term loan at closing and provides an additional term loan of up to $25 million, which is available for funding until July 14, 2027, subject to the achievement of certain revenue milestone and other customary conditions (the Perceptive Term Loan). The Company is required to comply with certain covenants under the Perceptive Credit Agreement including, among others, requirements as to financial reporting, restrictions on its ability to incur additional indebtedness and to pay any dividends or other distributions on capital stock, maintenance of a minimum cash balance, and achievement of certain specified trailing twelve-month net revenue targets. If the Company fails to comply with any covenants, payments or other terms of the Perceptive Credit Agreement and such failure constitutes an event of default, such event of default would give Agent the right to declare all borrowings outstanding, together with accrued and unpaid interest and fees, to be immediately due and payable. Further details of obligations under the Perceptive Credit Agreement are described in Note 7.

While the Company has taken actions to reduce operating expenses and working capital to align with anticipated revenue growth including implementing restructuring plans to streamline its overall organizational structure and renegotiating commitments with suppliers to reduce inventory, management expects to continue to incur operating losses in the near term while the Company makes investments to support its anticipated growth.

Furthermore, in September 2024, the Company received notice from the Nasdaq Stock Market LLC (Nasdaq) that it no longer complied with the minimum bid price requirement for continued listing on the Nasdaq Global Select Market. Although compliance was regained in December 2024, the Company received a second notice of non-compliance in February 2025 after again failing to meet the minimum bid price requirement. Following the Reverse Stock Split, the Company regained compliance. However, if the Company is unable to maintain compliance with the minimum bid price requirement or other applicable Nasdaq listing rules, it may not be able to maintain the listing of its common stock on Nasdaq, which could adversely affect its ability to issue additional securities or obtain additional financing on terms acceptable to it, or at all.

Management believes that the Company’s existing cash, cash equivalents, short-term investments, cash generated from sales, and proceeds recently received from the debt financing described in Note 7 as well as proceeds received from the Private Placement described in Note 8, will be sufficient to meet its anticipated needs for at least the next 12 months from the issuance date of the accompanying condensed financial statements.

Basis of Presentation

The accompanying condensed financial statements are unaudited and have been prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) and on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, that are necessary for the fair statement of the Company’s financial position, results of operations, comprehensive loss, and cash flows for the interim periods presented. The financial data and the other financial information disclosed in these notes to the condensed financial statements related to the three- and six-month periods are also unaudited. The results of operations for the three and six months ended June 30, 2025 are not necessarily indicative of the results of operations to be anticipated for any other future annual or interim period. The condensed balance sheet as of December 31, 2024 included herein was derived from the audited financial statements as of that date.

These unaudited condensed financial statements should be read in conjunction with the Company’s audited financial statements and related notes for the year ended December 31, 2024, which are included in the Annual Report on Form 10-K for the fiscal year ended December 31, 2024 filed with the Securities and Exchange Commission (SEC) on February 21, 2025 (2024 Annual Report).

All share amounts disclosed in the notes to the condensed financial statements are rounded to the nearest thousand except for per share data.

2. Summary of Significant Accounting Policies

Significant Accounting Policies

With the exception of the new accounting policy below, there have been no other new or material changes to the Company’s significant accounting policies as described in its 2024 Annual Report that have had a material impact on the Company’s condensed financial statements and related notes.

Common Stock Warrant

The Company has accounted for its freestanding warrants to purchase shares of the Company’s common stock as equity at fair value upon issuance primarily because the warrants are indexed to the Company’s own common stock. The Company estimated the fair value of these warrants using the Black-Scholes option pricing model, which is considered to be a Level 3 fair value measurement. Assumptions used in the pricing model were based on the individual characteristics of the warrants on the valuation date, as well as assumptions for expected volatility, expected term, and risk-free interest rate.

3. Revenue and Deferred Revenue

Disaggregation of Revenue

Revenue by source consists of the following (in thousands):

Remaining Performance Obligations and Contract Liabilities

As of June 30, 2025, the aggregate amount of the transaction price allocated to the remaining performance obligations related to customer service contracts that are unsatisfied or partially unsatisfied was $14.6 million, which is recorded as deferred revenue on the Company’s condensed balance sheets. Of that amount, $14.0 million will be recognized as revenue during the next 12 months and $0.6 million thereafter.

The contract liabilities consist of deferred revenue which represents payments received in advance of revenue recognition. Revenue under these agreements is recognized over the related service period. During the three and six months ended June 30, 2025, the Company recognized $4.7 million and $10.6 million of previously deferred revenue, respectively.

The following tables present the breakdown of the available-for-sale debt securities with unrealized losses as of June 30, 2025, and December 31, 2024 (in thousands):

Total |  | $ | 2,994 |  |  | $ | (1 | ) |  | $ | — |  |  | $ | — |  |  | $ | 2,994 |  |  | $ | (1 | )

The unrealized losses on the Company’s available-for-sale debt securities were caused by interest rate increases. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost basis of the investments. As of June 30, 2025, the Company does not intend to sell the investments, and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost basis, which may be at maturity. Additional factors considered in determining the treatment of unrealized losses include the financial condition and near-term prospects of the investee, the extent of the loss related to the credit of the issuer, and the expected cash flows from the security. For the three and six months ended June 30, 2025 and 2024, the Company did not recognize credit loss related to available-for-sale debt securities.

6. Commitments and Contingencies

Litigation

On August 29, 2024, a purported stockholder class action lawsuit (the Porcelli Complaint), Porcelli v. Outset Medical, Inc., et al., 5:24-cv-06124-EJD, was filed in the U.S. District Court for the Northern District of California, against the Company, its Chief Executive Officer, and then-Chief Financial Officer. On October 18, 2024, a second purported stockholder class action lawsuit (the Plymouth Complaint; together with the Porcelli Complaint, the Class Actions), Plymouth County Retirement Association v. Outset Medical, Inc., et al., 5:24-cv-06124-HSG, was filed in the same court. The second lawsuit also named the Company’s prior Chief Financial Officer as a defendant (together with the CEO and then-CFO, the Class Defendants). The Porcelli Complaint alleged that, between August 1, 2022 and August 7, 2024, defendants made materially false or misleading statements in violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (Exchange Act) regarding the Company’s business, operations, and prospects related to the sale and marketing of the Tablo Hemodialysis System and TabloCart with Prefiltration, including concerning the impact of certain FDA processes for these products on the Company’s revenue growth. The Plymouth Complaint alleged similar violations between September 15, 2020 and August 7, 2024. On March 18, 2025, the court consolidated the Class Actions into one action captioned In re Outset Medical, Inc. Securities Litigation, Case No. 5:24-cv-06124-EJD, appointing a lead Plaintiff and lead Counsel. The lead plaintiff filed its consolidated amended complaint on June 6, 2025. The Class Defendants’ deadline to respond to or file a motion to dismiss is August 14, 2025, with additional briefing to follow.

On November 29, 2024, an Outset stockholder purporting to act on behalf of the Company filed an action in the U.S. District Court for the Northern District of California against current and former members of Outset’s Board of Directors and certain of its officers (the Derivative Defendants), alleging that the Derivative Defendants breached their fiduciary duties to the Company in connection with the same alleged events and alleged materially false and misleading statements asserted in the Class Actions described above. Three additional substantively duplicative actions were filed in the U.S. District Court for the Northern District of California on April 28, 2025, May 8, 2025, and June 16, 2025. The complaints seek unspecified monetary damages and other relief. On July 17, 2025, the court entered a stay of all derivative actions pending the outcome of the Class Defendants’ forthcoming motion to dismiss the consolidated amended complaint.

The cases are at a very early stage and the Company cannot currently estimate the loss or the range of possible losses it may experience in connection with this litigation.

In addition, from time to time, the Company may become involved in other legal proceedings or investigations, which could have an adverse impact on its reputation, business and financial condition and divert the attention of the Company’s management from the operation of the Company’s business.

Indemnification

In the ordinary course of business, the Company often includes standard indemnification provisions in its arrangements with its partners, customers and suppliers. Pursuant to these provisions, the Company may be obligated to indemnify such parties for losses or claims suffered or incurred in connection with its service, breach of representations or covenants, intellectual property infringement or other claims made against such parties. These provisions may limit the time within which an indemnification claim can be made. It is not possible to determine the maximum potential amount under these indemnification obligations due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. To date, the Company has not incurred any material costs as a result of such indemnification obligations and has not accrued any liabilities related to such obligations in these financial statements.

7. Term Loans

Term loans consist of the following (in thousands):

|  | June 30, |  |  | December 31, |

Term loans, noncurrent |  | $ | 94,814 |  |  | $ | 197,375 |

SLR Credit Facilities

In November 2022, the Company entered into two senior secured credit facilities, which collectively provide for borrowings of up to $300.0 million as follows: (i) up to a $250.0 million term loan facility pursuant to a loan and security agreement (the SLR Loan Agreement) among SLR Investment Corp., as collateral agent (SLR Agent), the lenders from time to time party thereto (the Term Loan Lenders) and the Company (the SLR Term Loan Facility), and (ii) up to a $50.0 million asset-based revolving credit facility pursuant to a credit agreement (the SLR Revolving Credit Agreement, together with the SLR Loan Agreement, the SLR Credit Facility Agreements) among Gemino Healthcare Finance, LLC d/b/a SLR Healthcare ABL, as lender (ABL Lender), and the Company (the SLR Revolver, together with the SLR Term Loan Facility, the SLR Credit Facilities).

As of December 31, 2024, $200.0 million was outstanding under the SLR Term Loan Facility and no amounts were outstanding under the SLR Revolver. On January 3, 2025, the Company terminated the SLR Credit Facility Agreements and repaid in full all amounts due, including a final payment of $7.5 million and a termination fee of $0.1 million, using the proceeds from the Perceptive Term Loan as described below, together with cash on hand. The repayment of the SLR Credit Facilities was accounted for as a debt extinguishment, which resulted in a loss on extinguishment of $7.7 million recorded in the accompanying condensed statements of operations for the six months ended June 30, 2025.

Perceptive Term Loan

On January 3, 2025, the Company entered into a senior secured credit facility for borrowings up to an aggregate principal amount of $125.0 million pursuant to the Perceptive Credit Agreement with Perceptive Credit Holdings IV, LP (who also participated in the Private Placement). Pursuant to the terms and conditions of the Perceptive Credit Agreement, the lenders agreed to extend term loans to the Company in an aggregate principal amount of up to $125.0 million, comprised of (i) a term loan of $100.0 million (the Initial Term Loan), which was funded on January 8, 2025 (the Closing Date), and (ii) a delayed draw term loan of up to $25.0 million (the Delayed Draw Loan). The Initial Term Loan and the Delayed Draw Loan are referred to collectively as the Perceptive Term Loans. The Delayed Draw Loan is available for funding until July 14, 2027, subject to the achievement of a specific revenue milestone and other customary conditions.

The principal amount outstanding under the Loans will accrue interest at a rate per annum equal to (i) the greater of (a) one-month term SOFR or (b) 4.00% per annum, plus (ii) an applicable margin of 8.00%, payable monthly in arrears. During the first two years after the Closing Date, a portion of the accrued interest equal to 1.50% per annum will be paid in kind and added to the principal amount of the Loans on each monthly interest payment date. The outstanding principal amount of the Loans will be due and payable on the five year anniversary of the Closing Date (the Maturity Date).

The Company paid the lenders a non-refundable closing fee in the amount of $1.0 million in respect of the Initial Term Loan on the Closing Date. The Company is obligated to pay the lenders a non-refundable closing fee in the amount of $250,000 in respect of the Delayed Draw Loan, to be due and payable upon the funding of the Delayed Draw Loan.

On the Closing Date, the Company issued to Perceptive Credit Holdings IV, LP as the initial lender a warrant to purchase 375,000 of shares of the Company’s common stock (the Closing Date Warrant), at an exercise price equal to $12.00 per share. If the Company draws the Delayed Draw Loan, the Company is required to issue additional warrant(s) to the lenders to purchase 94,000 shares of the Company’s common stock (the Delayed Draw Warrant), at an exercise price equal to the average closing price of the Company’s common stock for the 5 trading days immediately preceding the issuance date of the Delayed Draw Warrant. Both the Closing Date Warrant and the Delayed Draw Warrant, if issued, are exercisable during the seven years after the date of issuance.

The fair value of the Closing Date Warrant of $4.4 million and the debt issuance costs paid directly to Perceptive Credit Holdings IV, LP along with other debt issuance costs amounting to $6.5 million were accounted for as a direct deduction from the term loan balance on the balance sheets and are being recognized as non-cash interest expense over the term of the loan using the effective interest method.

The Company may voluntarily prepay the outstanding loan(s), subject to a prepayment premium of (i) 10.0% of the principal amount of the prepaid loan(s), if prepaid prior to or on the first anniversary of the Closing Date, (ii) 8.0% of the principal amount of the prepaid Loans, if prepaid after the first anniversary of the Closing Date through and including the second anniversary of the

13

Closing Date, (iii) 4.0% of the principal amount of the prepaid loan(s), if prepaid after the second anniversary of the Closing Date through and including the third anniversary of the Closing Date, (iv) 2.0% of the principal amount of the prepaid Loans, if prepaid after the third anniversary of the Closing Date through and including the fourth anniversary of the Closing Date, and (v) 0.00% of the principal amount of the prepaid loan(s), if prepaid after the fourth anniversary of the Closing Date.

The Perceptive Credit Agreement contains customary representations and warranties and customary affirmative and negative covenants, including, among others, requirements as to financial reporting and insurance and restrictions on the Company’s ability to dispose of its business or property, to change its line of business, to liquidate or dissolve, to enter into any change in control transaction, to merge or consolidate with any other entity or to acquire all or substantially all the capital stock or property of another entity, to incur additional indebtedness, to incur liens on its property or to pay any dividends or other distributions on capital stock, in each case with certain exceptions. The Company has also agreed to certain financial covenants that require the Company to (i) maintain a minimum cash balance of at least $10.0 million in accounts subject to control agreements in favor of Agent, and (ii) achieve certain trailing twelve-month net revenue targets as set forth in the Perceptive Credit Agreement.

In addition, the Perceptive Credit Agreement contains customary events of default that entitle the Agent to cause the Company’s indebtedness under the Perceptive Credit Agreement to become immediately due and payable, and to exercise remedies against the Company and the collateral securing the obligations owed under the Perceptive Credit Agreement. Under the Perceptive Credit Agreement, an event of default will occur if, among other things, the Company fails to make payments under the Perceptive Credit Agreement, the Company breaches certain covenants under the Perceptive Credit Agreement, subject to specified cure periods with respect to certain breaches, a material adverse change or a material regulatory event has occurred under the Perceptive Credit Agreement, or the Company or its assets become subject to certain legal proceedings, such as bankruptcy proceedings. Upon the occurrence and for the duration of an event of default, an additional default interest rate equal to 4.0% per annum will apply to all obligations owed under the Perceptive Credit Agreement.

8. Convertible Preferred Stock and Stockholders' Equity

Convertible Preferred Stock

The Company is authorized to issue a total of 5,000,000 shares of preferred stock, par value $0.001 per share. In connection with the Private Placement described below, the Company filed a Certificate of Designation of Preferences, Rights and Limitations of Series A Convertible Preferred Stock with the Delaware Secretary of State on January 7, 2025 (the Certificate of Designation) to set forth the preferences, rights and limitations of the Series A Convertible Preferred Stock. The Company has designated a total of 863,000 shares as Series A Convertible Preferred Stock, which are non-voting and not redeemable.

On January 3, 2025, the Company entered into securities purchase agreements with various investors, including certain of the Company’s directors, officers and employees (the Investors) for the issuance and sale by the Company of an aggregate of 863,000 shares of Series A Convertible Preferred Stock, par value $0.001 per share, at a purchase price of $200.00 per share in the Private Placement. The sale of 844,000 shares of Series A Convertible Preferred Stock to institutional investors closed on January 8, 2025, with gross proceeds, before deducting placement agent fees and other offering expenses, of $168.8 million. On March 7, 2025, following stockholder approval of the Company’s issuance of shares of Series A Convertible Preferred Stock and shares of the Company's common stock issuable upon the conversion thereof to certain of the Company’s directors, officers and employees at the special meeting of stockholders held on March 5, 2025 (the Special Meeting), the Company issued 19,000 shares of Series A Convertible Preferred Stock to certain of the Company’s directors, officers and employees, with gross proceeds, before deducting offering expenses, of $3.9 million.

On March 10, 2025, following the stockholder approval of the Company’s issuance of common stock in excess of 20% of the Company’s then outstanding shares of common stock at the Special Meeting, 842,000 shares of Series A Convertible Preferred Stock were converted into 14,046,000 shares of the Company’s common stock at the conversion price of $12.00 per share in accordance with the Certificate of Designation. Following the conversion, 21,000 shares of the Series A Convertible Preferred Stock remain issued and outstanding as of June 30, 2025.

In the event of any voluntary or involuntary liquidation, dissolution or winding-up of the Company, the Series A Convertible Preferred Stock shall rank on parity with the common stock as to distributions of assets. Series A Convertible Preferred Stock holders shall be entitled to receive, and the Company shall pay, dividends on shares of the Series A Convertible Preferred Stock (on an as-if-converted-to-Common-Stock basis) equal to and in the same form, and in the same manner, as dividends actually paid on shares of the common stock when, as and if such dividends (other than dividends payable in the form of common stock) are paid on shares of the common stock.

Based on the attributes of the Series A Convertible Preferred Stock as described above, the Company has accounted for the Series A Convertible Preferred Stock as a component of permanent stockholders’ equity.

Common Stock Warrants

As discussed in Note 7 above, the Company issued a warrant to Perceptive Credit Holdings IV, LP to purchase 375,000 of shares of the Company’s common stock, at an exercise price equal to $12.00 per share, in January 2025. This warrant is immediately exercisable upon issuance, and expires seven years after the date of issuance, January 2032. This warrant is classified as a component of permanent stockholders’ equity. The Company determined the fair value using the Black-Scholes option pricing model with the following assumptions on the date of issuance: common stock price of $14.66 per share, expected volatility of 93%, expected term of 7 years, and risk-free interest rate of 4.56%.

As of June 30, 2025, aggregate common stock warrants of 379,000 shares with a weighted average exercise price of $13.19 per share were outstanding and exercisable. Of these warrants, 4,000 shares expire in September 2025.

9. Equity Incentive Plan

Equity Incentive Plan

At the Company’s annual meeting of stockholders held on June 2, 2025 (the 2025 Annual Meeting), the Company’s stockholders approved an amendment to the Company’s 2020 Equity Incentive Plan (2020 Plan) to increase the number of shares of common stock available for issuance under the plan by 1,950,000 shares. As of June 30, 2025, 1,370,000 shares were reserved for future issuance under the 2020 Plan.

Employee Share Purchase Plan (ESPP)

At the 2025 Annual Meeting, the Company’s stockholders approved an amendment to the Company’s ESPP to increase the number of shares of common stock available for issuance under the plan by 255,000 shares. As of June 30, 2025, 276,000 shares of common stock were reserved for issuance in connection with the current and future offering periods under the ESPP.

Restricted Stock

The Company issues restricted stock units (RSUs) and performance stock units (PSUs), both of which are considered restricted stock. The Company grants restricted stock pursuant to the 2020 Plan and satisfies such grants through the issuance of new shares. RSUs are share awards that, upon vesting, will deliver to the holder shares of the Company’s common stock.

RSUs with a service-based vesting condition granted to a grantee, beginning in February 2022, generally vest over a three-year period as follows: (i) 25% on the first anniversary of the vesting commencement date, 25% quarterly over the course of the second year, and 50% quarterly over the course of the third year, or (ii) 33% on the first anniversary of the vesting commencement date, with the balance vesting quarterly over the remaining two years.

Annual RSUs granted to non-executive employees in 2025 vest over one year with 100% vesting on the first anniversary of the grant date while the annual RSUs granted to executives in 2025 vest over a two-year period with 50% vesting on the first anniversary of the vesting commencement date, and the remaining 50% vesting quarterly over the following year.

Annual RSUs granted to non-executive employees in 2024 vest over a two-year period at a rate of 50% on the first anniversary of the original vesting date, with the balance vesting quarterly over the remaining one year.

Prior to February 2022, RSUs with a service-based vesting condition granted to a grantee generally vest at a rate of 25% on the first anniversary of the original vesting date, with the balance vesting quarterly over the remaining three years.

Since 2022, the Company has granted a mix of 50% PSUs and 50% RSUs to its CEO, and a mix of 20% PSUs and 80% RSUs to its other executive officers and certain other senior leaders on an annual basis. These PSUs are earned and vest based on achievement aga inst a performance-based metric and a market-based metric as follows:

•
Performance-based vesting conditions:
o
PSUs granted in 2022 through 2024 are earned based on the number of patients treating at home on Tablo as of the end of the second or third year following the grant date (Year 2 or Year 3), with earned units vesting either (i) 50% after certification of achievement following the end of Year 2 and 50% at the end of Year 3 or (ii) 100% after certification of achievement following the end of Year 3 (Home PSUs); or
o
PSUs granted in 2025 are earned based on the Company’s three-year non-GAAP cumulative earnings before income tax, depreciation and amortization (EBITDA) at the end of 2027, with 100% of earned units vesting after certification of the achievement level following the end of 2027 (EBITDA PSUs).

15

•
Market-based vesting conditions:
o
PSUs granted in 2022 through 2025 are earned based on the Company’s relative total stockholder return (Relative TSR) at the end of a two-year or three-year performance period as compared to companies in a pre-determined index of medical device companies, in each case, with 100% of earned units vesting at the end of Year 3, or after certification of achievement following the end of the three-year performance period (Relative TSR PSUs).

The number of units earned varies based on actual performance as follows: (i) from 0% to 200% (250% for the CEO) of the target number of the Home PSUs and EBITDA PSUs granted, (ii) from 75% to 150% (250% for the CEO) of the target number of Relative TSR PSUs granted in 2022 and 2023 and (iii) from 0% to 200% (250% for the CEO) of the target number of Relative TSR PSUs granted in 2024 and 2025.

The grant dates for the Home PSUs and EBITDA PSUs are not considered established until the Compensation Committee of the Board approves the target and it is communicated to the award recipients, which then triggers the service inception date, the fair value of the awards, and the associated expense recognition period. Once the grant dates for the Home PSUs and EBITDA PSUs have been established, the related stock-based compensation expense would be recorded based on the forecasted performance, which is reassessed each reporting period based on the probability of achieving the performance conditions.

In 2024, the Company also granted a new type of PSU award to executive officers and certain other senior leaders which is earned and vests based on appreciation of the Company’s stock price above pre-determined stock price triggers or achievement of specified non-GAAP operating income targets over a performance period of up to three years.

12. Segment

The key measure of segment profit or loss that the Company’s chief operating decision maker (CODM), its Chief Executive Officer, uses to allocate resources and assess performance is the Company’s net loss, as reported on the accompanying condensed statements of operations. Net income is used to monitor budget versus actual results.

There are no intra-entity sales or transfers. All expense categories on the accompanying condensed statements of operations are significant and there are no other expense categories regularly provided to the CODM beyond those disclosed in the accompanying condensed statements of operations. The CODM manages the business using expense information as well as regularly provided budgeted or forecasted expense information for the single operating segment. The measure of segment assets is reported on the accompanying condensed balance sheets as total consolidated assets with particular emphasis on the Company’s available liquidity, including its cash, cash equivalents, restricted cash, and short-term investments.

13. Workforce reduction

In order to improve operational efficiencies, reduce operating expenses and streamline its overall organizational structure, the Company implemented two organizational restructuring plans to reduce its workforce in the fourth quarter of 2023 and May 2024 and incurred restructuring charges of $2.5 million in fiscal year 2023 and $2.7 million through the first half of fiscal year 2024 for employee severance and other termination benefits.

In connection with steps the Company took to help optimize its commercial organization, and to help improve operational efficiencies and reduce operating expenses to align with anticipated revenue growth, in the third quarter of 2024, the Company completed an additional restructuring plan primarily impacting its commercial organization. The Company incurred restructuring charges of $1.4 million in the third quarter of 2024 for employee severance and other termination benefits associated with this restructuring.

In January 2025, the Company implemented another restructuring plan and, as a result, estimated and recognized restructuring charges of $1.5 million as of December 31, 2024 for employee severance and other termination benefits. Restructuring accruals were based upon management estimates at the time and adjusted based on the changes in facts and circumstances subsequent to the date the original liability was recorded.

The following table sets forth severance and related benefits charges included in the accompanying condensed statements of operations (in thousands):

|  | Six Months Ended |

Overview

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, our Tablo® Hemodialysis System (Tablo) frees patients and providers from the burdensome infrastructure required to operate traditional dialysis machines. The integration of water purification and on-demand dialysate production in a single 35-inch compact console enables Tablo to serve as a dialysis clinic on wheels. With a simple-to-use touchscreen interface, two-way wireless data transmission and a proprietary data analytics platform, Tablo is a holistic approach to dialysis care. Unlike existing hemodialysis machines, which have limited clinical versatility across care settings, Tablo can be used seamlessly across multiple care settings and a wide range of clinical applications. Tablo is cleared by the FDA for use in the hospital, clinic, or home setting.

Tablo leverages cloud technology, making it possible for providers to monitor devices remotely, view treatment data, perform patient and population analytics, and automate clinical recordkeeping. Tablo’s wireless connectivity enables us to release training, new features and enhancements over-the-air without interventions by field service engineers. Tablo’s connectedness allows continuous streaming of over 500,000 device performance data points to the cloud for every treatment. We use this data, in conjunction with our diagnostic and predictive algorithms, to monitor device performance, identify and diagnose failures and, in some instances, predict and prevent potential future device failures or malfunctions. In effect, this contributes to a reduction in service hours and an increase in device uptime.

We have generated meaningful evidence to demonstrate that providers can realize significant operational efficiencies, including reducing the cost of their dialysis programs. In addition, Tablo has been shown to deliver robust clinical care. In studies and surveys we have conducted, patients have reported quality of life benefits on Tablo compared to other dialysis machines. We believe Tablo empowers patients, who have traditionally been passive recipients of care, to regain agency and ownership of their treatment.

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 care market has demonstrated Tablo’s clinical flexibility and operational versatility, while also delivering meaningful cost savings to the providers. In addition, we are also working with skilled nursing facilities (SNFs), sub-acute long-term acute care hospitals (LTACHs), and other post-acute providers to raise awareness of Tablo’s economic and clinical benefits to them and to patients. We plan to continue leveraging our commercial infrastructure to broaden our installed base in the acute and post-acute care markets, as well as driving utilization and fleet expansion with our existing customers.

18

Tablo is also utilized for home-based dialysis. We believe our ability to reduce training time, patient dropout, and the supplies and infrastructure required to deliver dialysis in the home can drive efficiency and economic improvements to the home care model. In our home investigational device exemption trial, patients reported specific quality of life improvements compared to their experience on the incumbent home dialysis machine. To penetrate this market successfully, we have made investments in and continue to focus on refining our home distribution, logistics and support systems to help ensure they are ready for scale. We are also working with providers, patients, and payors to increase awareness and adoption of transitional care units as a bridge to home-based therapy.

We generate revenue from the placement of Tablo consoles along with accessories, and shipping and handling charged to customers, which revenue is recognized up-front. We also earn recurring revenue from sales of consumables, including Tablo cartridge, and services, which generates significant total revenue over the life of Tablo consoles. Our total revenues were $31.4 million and $27.4 million for the three months ended June 30, 2025 and 2024, respectively, and $61.2 million and $55.6 million for the six months ended June 30, 2025 and 2024, respectively.

We primarily sell our solutions through our direct sales organization, which covers most major metropolitan markets in the United States. Our sales organization is comprised of our capital sales team, responsible for generating new customer demand for Tablo, and our clinical sales team, responsible for driving utilization and fleet expansion of Tablo at existing customer sites. In addition, our field service team provides maintenance services and product support to our customers. Our field sales and service teams represent 59% of our total full-time employees as of June 30, 2025. 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.

Recent Developments

In July 2023, we received a warning letter (the Warning Letter) from the FDA that raised two observations. The first observation asserted that certain content reviewed by the FDA and found on our website promotes Continuous Renal Replacement Therapy (CRRT), a modality outside of the current indications for Tablo. The second observation asserted that TabloCart with Prefiltration required prior 510(k) clearance for marketing authorization. TabloCart with Prefiltration is an accessory to Tablo launched in the third quarter of 2022. We took action to address the first observation regarding CRRT promotion through revision of processes and procedures and updates to existing labeling and promotional materials. We also took action to address the second observation regarding TabloCart with Prefiltration. Although we evaluated TabloCart with Prefiltration prior to marketing and distributing the product and concluded that no marketing authorization was necessary, we paused distribution of TabloCart with Prefiltration pending the FDA’s review and clearance of a 510(k) application for the same that we submitted in September 2023. In early May 2024, we received 510(k) clearance from the FDA for TabloCart with Prefiltration, and we have resumed distribution of TabloCart with Prefiltration. In February 2025, we were notified by the FDA that the issues cited in the Warning Letter have been addressed.

Key Factors Affecting Our Performance

We believe that our financial performance has been, and in the foreseeable future will continue to be, primarily driven by the following factors. While we believe each of these factors presents significant opportunities for our business, they also pose important challenges that we must successfully address in order to sustain our growth and improve our results of operations. Our ability to successfully address the factors below is subject to various risks and uncertainties, including those described in the section titled “Risk Factors.”

Market Acceptance of Tablo in Acute Setting

We plan to further broaden our installed base by continuing to target national and regional integrated delivery networks and health systems, SNFs, LTACHs and other post-acute providers. In addition, we focus on driving utilization and fleet expansion with existing customers by providing an exceptional user experience delivered through our commercial team and a steady release of software enhancements that amplify Tablo’s operational reliability and clinical versatility. Our ability to successfully execute on this strategy, and thereby increase our revenue in the acute market, will depend on several factors. These factors include our ability to recover from the adverse impact in the field from the Warning Letter as we resume distribution of TabloCart with Prefiltration, as well as the success of our initiatives to optimize and further evolve our commercial organization, infrastructure and sales processes to support the growth of our business in the acute and post-acute care markets as we focus more heavily on enterprise selling and transition beyond earlier stage adoption of Tablo.

Expansion of Tablo within the Home Setting

We believe that a significant growth opportunity exists within the home hemodialysis market. We are partnering with innovative dialysis clinic providers, health systems and other adjacent healthcare providers who are motivated to grow their home hemodialysis population, and who share our vision of creating a seamless and supported transition to the home. We are also investing in market development over the longer term to expand the home hemodialysis market itself. The expansion of the home hemodialysis market and our ability to penetrate this market will be an important factor in driving the future growth of our business. In addition, the

19

success of our efforts to expand within the home market, help grow new home programs and increase our revenue generated from home-based dialysis on the timeline that we anticipate will depend on several factors. These factors include the success of our initiatives to optimize and further evolve our commercial organization, infrastructure and sales processes as we scale our business in the home market.

Gross Margin

Our ability to expand our gross margins depends on: first, our ability to continue to sell Tablo cartridges, services, and accessories for Tablo consoles; second, our ability to reduce the cost of service and third, our ability to reduce the cost to manufacture Tablo consoles. Our ability to expand gross margins will also depend in part on our ability to control the average selling prices of our products and services, including by selling higher-margin accessories, consumables and services. Further, we will continue to utilize our cloud-based data system, as well as enhanced product and support performance, to improve service margin and drive down service costs per console. In addition, over the past several years, we have moved the production of Tablo consoles and a majority of Tablo cartridges in-house to our manufacturing facility in Tijuana, Mexico which we operate in collaboration with TACNA, as part of our cost reduction activities. This has helped further our long-term gross margin expansion and supply continuity strategies while reducing the costs of Tablo console production and improving the flexibility of our operations. We will continue our cost reduction activities by using our design, engineering, supply chain and manufacturing capabilities to help further advance and improve the efficiency of our manufacturing processes, lowering the cost of parts and components and lowering our costs of production. Our ability to expand gross margins depends on our ability to successfully execute these strategies, as well as the impact of macroeconomic factors described below, including the tariffs imposed by the current administration.

Profitability Initiatives

Our ability to achieve and sustain profitability depends on several key factors: first, our ability to grow our revenue while expanding gross margins, as discussed above; second, our ability to optimize operating expenses; and third, our ability to optimize working capital. We have undertaken various initiatives designed to improve operational efficiencies, reduce operating expenses to align with anticipated levels of revenue growth and streamline our overall cost structure, including several organizational restructurings implemented beginning in the fourth quarter of 2023 through early 2025. We are also taking steps to improve our ability to efficiently manage working capital, including inventory. Our ability to transition to profitability will depend on the success of our efforts to optimize spending and working capital, including inventory.

Impacts of Macroeconomic Factors

Global macroeconomic conditions, including inflationary pressures, rising interest rates, changes in tariff or trade laws and policies (such as the tariffs imposed by the current administration), increased labor costs, staffing shortages and global supply chain disruptions, may impact our business and results of operations, and those of our customers, manufacturing partners and suppliers. As the duration and severity of these macroeconomic conditions remain uncertain and depend on various factors, we cannot predict what effects these macroeconomic conditions will ultimately have on our business and results of operations, our customers, or our suppliers.

Beginning in the third quarter of 2023, we began to observe an increasing number of our existing and prospective customers deferring their decisions to purchase Tablo in an environment of rising interest rates and more cautious capital spending. These deferrals served to elongate our sales cycle and the timing of delivery and installations, which, in turn, contributed to an adverse impact on our bookings and revenues starting in the second half of 2023 and through 2024. We may see disruption from this in future periods. In addition, ongoing uncertainty relating to various policy changes under the current administration – including developments in trade policy (such as increased tariffs), changes in interest rate policy, potential reductions in government reimbursement and shifts in broader healthcare policy – could increase financial pressures faced by our existing and prospective hospital customers. These actual or anticipated policy changes may lead to higher operating costs for our customers, as well as tighter operating budgets and more cautious capital spending decisions. Additionally, broader economic uncertainty and market volatility – driven in part by these evolving policies – could exacerbate financial strain on our customers, potentially resulting in delayed or reduced purchases of our products and services. These factors could adversely impact our revenues, results of operations and financial condition in future periods.

If our customers continue to face prolonged periods of rising interest rates, capital budget constraints, volatility, uncertainty, staffing shortages, cash flow challenges, rising costs and other financial pressures, whether due to general macroeconomic conditions, evolving policy changes under the current administration (including trade policy developments, reductions in government reimbursement or shifts in healthcare policy), cybersecurity events or other factors, it could ultimately adversely impact our ability to expand existing customer relationships or attract new customers of Tablo, timely collect amounts due, effectively manage our inventory levels, and have a material adverse effect on our bookings, revenues, results of operations, financial condition, and, ultimately, our future growth and profitability.

From a supply chain perspective, 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, macroeconomic factors such as rising inflation, increasing labor costs, and surges and shifts in

20

consumer demand have disrupted the operations of certain of our third-party suppliers, resulting, in some cases, in increased lead times and higher component costs. We believe that localizing production of a majority of Tablo cartridges in Mexico (in-house at our manufacturing facility) has helped achieve cost reductions through lower freight costs, further our long-term gross margin expansion and supply continuity strategies and improve the flexibility of our operations. However, we may face increased supply chain constraints in the future, which 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 operations. Moreover, increased tariffs imposed by the current administration, including on goods imported into the United States from Mexico and China, could adversely impact our supply chain and distribution costs, as well as our ability to achieve sustainable gross margins. While we do not believe we have exposure to these potential tariffs as Tablo, TabloCart and Tablo cartridge are covered under a special exemption, we cannot predict what actions may ultimately be taken with respect to tariffs or trade relations between the United States and other countries (including Mexico and China), what products may be subject to such actions, or what actions may be taken by the other countries in retaliation.

Product revenue increased by $3.8 million, or 20%, for the three months ended June 30, 2025 as compared to the same period in the prior year. This increase was driven by a $2.0 million increase in consumable revenue due to growth in our console installed base and a $1.8 million increase in console revenue.

Product revenue increased by $4.7 million, or 12%, for the six months ended June 30, 2025 as compared to the same period in the prior year. This increase was driven by a $5.0 million increase in consumable revenue attributable to growth in our console

21

installed base, which was offset by a $0.3 million decrease in console revenue due to fewer consoles being sold in the current year period as compared to prior year period.

Service and other revenue increased for the three and six months ended June 30, 2025 as compared to the same periods in the prior year. The increase was primarily due to services associated with growth in our console installed base.

Gross Profit and Gross Margin

Gross profit increased for the three and six months ended June 30, 2025 as compared to the same periods in the prior year. Gross margin improved by 2.1 percentage points for the three months ended June 30, 2025 and 5.1 percentage points for the six months ended June 30, 2025 as compared to the same periods in the prior year. These improvements in gross profit and gross margin were primarily driven by higher average selling prices for consoles and consumables and lower unit cost per console. These improvements were slightly offset by lower gross margin on service and other revenue as a result of one-time strategic investment in service operations to enhance console reliability.

The decrease in interest income and other income, net for the three and six months ended June 30, 2025 as compared to the same periods in the prior year were driven by a lower average short-term investment balance in 2025.

22

The decreases in interest expense for the three and six months ended June 30, 2025 were primarily due to a lower outstanding term loan balance in 2025.

The loss on extinguishment of term loan of $7.7 million was recognized for the repayment of the SLR Term Loan in 2025, which included final payment and termination fees.

Liquidity and Capital Resources

Sources of Liquidity

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 equity securities, revenue from sales, debt financings, and proceeds from employee exercise of stock options and ESPP purchases.

As of June 30, 2025, we had cash, cash equivalents, restricted cash, and short-term investments of $187.4 million. In January and March 2025, we sold 863,340 shares of Series A Convertible Preferred Stock at a price of $200.00 per share in the Private Placement for total gross proceeds of $172.7 million, before deducting placement agent fees and other offering expenses. Subsequently, 842,753 shares of Series A Convertible Preferred Stock were converted into 14,045,866 shares of our common stock.

In addition, in January 2025, we entered into the Perceptive Credit Agreement with Perceptive Credit Holdings IV, LP, which provided a $100 million 5-year term loan at closing and provides an additional term loan of up to $25 million, which is available for funding until July 14, 2027, subject to achievement of a specified revenue milestone and other customary conditions.

We are required to comply with certain covenants under the Perceptive Credit Agreement, including, among others, requirements as to financial reporting, restrictions on our ability to incur additional indebtedness and to pay any dividends or other distributions on capital stock, maintenance of a minimum cash balance, and achievement of certain specified trailing twelve-month net revenue targets. If we fail to comply with any covenants, payments or other terms of the Perceptive Credit Agreement and such failure constitutes an event of default thereunder, such event of default would give Agent the right to declare all borrowings outstanding, together with accrued and unpaid interest and fees, to be immediately due and payable

While we have taken actions to reduce operating expenses and working capital to align with anticipated revenue growth including implementing restructuring plans to streamline our overall organizational structure and renegotiating commitments with suppliers to reduce inventory, we expect to continue 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, which may require refinancing or amending the terms of our existing debt, or other sources. If this financing is not available to us at adequate levels or on acceptable terms, we may need to further evaluate 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. We are subject to covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional capital through debt financing (including through our existing debt), we may be subject to an increase in our interest expense which may negatively affect our cash flow.

In September 2024, we received notice from the Listing Qualifications staff of Nasdaq that we no longer complied with the minimum bid price requirement for continued listing on the Nasdaq Global Select Market. Although compliance was regained in December 2024, we received a second notice of non-compliance in February 2025 after again failing to meet the minimum bid price requirement. Following the Reverse Stock Split, the Company regained compliance. However, if we are unable to maintain compliance with the minimum bid price requirement or other applicable Nasdaq listing rules, we may not be able to maintain the listing of our common stock on Nasdaq, which could adversely affect our ability to issue additional securities or obtain additional financing on terms acceptable to us, or at all.

We believe that our existing cash, cash equivalents and short-term investments, cash generated from sales, and proceeds received from the debt financing and the Private Placement described in Note 7 and 8, respectively, of the accompanying condensed financial statements above, will be sufficient to meet our anticipated needs for at least the next 12 months from the issuance date of this Quarterly Report.

Cash Flows Summary

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

|  | Six Months Ended June 30, |
|  | 2025 |  |  | 2024 |
Net cash (used in) provided by: |  |  |  |  |  |
Operating activities |  | $ | (30,486 | ) |  | $ | (79,247 | )
Investing activities |  |  | (109,241 | ) |  |  | (20,090 | )
Financing activities |  |  | 55,272 |  |  |  | 68,687 |
Net decrease in cash, cash equivalents and restricted cash |  | $ | (84,455 | ) |  | $ | (30,650 | )

Operating Activities

The net cash used in operating activities of $30.5 million for the six months ended June 30, 2025 was due to a net loss of $44.3 million, a net cash outflow from the change in our operating assets and liabilities of $5.3 million, and the amortization of premiums on investments of $1.0 million, which were adjusted by loss on extinguishment of term loan of $7.7 million, stock-based compensation expense of $6.5 million, depreciation and amortization of $2.4 million, provision for credit losses of $1.6 million, non-cash interest expense of $1.3 million, non-cash lease expense of $0.8 million, and provision for inventories of $0.2 million. The net cash outflow from operating assets and liabilities was primarily due to a decrease in accrued compensation and related benefits resulting from the payouts of 2024 annual cash bonus, a decrease in accrued interest as a result of the termination of the SLR Term Loan, a decrease in accounts payable, an increase in accounts receivable resulting from the timing of collection and decreases in operating lease liabilities and accrued warranty liability. The net cash outflow from operating assets and liabilities was partially offset by a decrease in inventory, an increase in deferred revenue due to growth in our business, increases in accrued expenses and other current liabilities and a decrease in prepaid expenses and other assets.

Investing Activities

The net cash used in investing activities of $109.2 million for the six months ended June 30, 2025 was due to purchases of short-term investment securities of $153.7 million and purchases of property and equipment of $0.4 million, which was partially offset by the maturities of short-term investment securities of $44.8 million.

Financing Activities

The net cash provided by financing activities of $55.3 million for the six months ended June 30, 2025 was due to net proceeds of $161.5 million from the issuance of Series A Convertible Preferred Stock, net proceeds of $98.3 million from borrowings under the Perceptive Term Loan Facility, and proceeds from ESPP purchases, partially offset by cash outflow of $205.0 million in repayment of the SLR Term Loan which included final payment and termination fees.

Critical Accounting Estimates

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 new or significant changes in our critical accounting estimates as compared to the critical accounting estimates disclosed in Part II Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our 2024 Annual Report.

Item 3. Quantitative and Qualitati ve Disclosures About Market Risk

Not applicable.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

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

24

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. Disclosure controls and procedures are also designed to provide reasonable assurance that such information is accumulated and communicated to our management, including our Chief Executive Officer and the 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 end of the period covered by this Quarterly Report.

Changes in Internal Control over Financial Reporting

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.

PART II—OTHER INFORMATION

Item 1. Legal Proceedings.

The information set forth under “Litigation” in Note 6, Commitments and Contingencies, of the notes accompanying our unaudited condensed financial statements in this Quarterly Report is incorporated herein by reference.

Item 1A. Ri sk Factors.

You should carefully consider the risk factors discussed in Part I, “Item 1A. Risk Factors” in our 2024 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, 2025 (Q1 2025 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 2024 Annual Report, as updated by our Q1 2025 Quarterly Report, except as set forth below. The risks described in our 2024 Annual Report and Q1 2025 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.

Our customers may face financial pressures including, but not limited to, capital budget constraints, staffing shortages and increased costs, that have had, and may continue to have, a negative impact on our financial condition or results of operations.

Beginning in 2022, our existing and prospective customers faced shortages of skilled nurses and other clinical personnel as well as increased labor costs, combined with economic pressures resulting from general economic and financial market conditions, primarily escalating inflation, tightening hospital operating budgets and increased scrutiny of capital purchase decisions, all of which generally have the effect of lengthening the average sales cycle and elongating the timing of installations. These factors negatively impacted our customer base on pipeline development and installation schedules, which, in turn, negatively impacted our bookings, delayed our shipments and adversely impacted our revenues for 2022 and, to a lesser extent, 2023.

Beginning in the third quarter of 2023, we began to observe an increasing number of our existing and prospective customers deferring their decisions to purchase Tablo in an environment of rising interest rates and more cautious capital spending. These deferrals served to further elongate our sales cycle and the timing of delivery and installations which in turn, contributed to an adverse impact on our bookings and revenues starting in the second half of 2023, and through 2024. We have no assurance that these impacts will abate in future periods.

Moreover, in February 2024, Change Healthcare, a large provider of healthcare payment systems, experienced a cyberattack on its information technology systems, causing disruptions to healthcare providers across the United States, including financial impacts such as reduced reimbursements and cash flow. We believe several of our customers experiencing these disruptions deferred both Tablo console and treatment purchases until their cash flow normalized, adversely impacting our revenues for the first quarter of 2024.

In addition, ongoing uncertainty relating to various policy changes under the current administration – including developments in trade policy (such as increased tariffs), changes in interest rate policy, potential reductions in government reimbursement and shifts in broader healthcare policy – could increase financial pressures faced by our existing and prospective hospital customers. These actual or anticipated policy changes may lead to higher operating costs for our customers, as well as tighter operating budgets and more cautious capital spending decisions. Additionally, broader economic uncertainty and market volatility – driven in part by these evolving policies – could exacerbate financial strain on our customers, potentially resulting in delayed or reduced purchases of our products and services. These factors could adversely impact our revenues, results of operations and financial condition in future periods.

We also believe that there will continue to be proposals and other actions by legislators and other policymakers at both the federal and state levels, and by regulators and third-party payors to reduce costs. For example, the recently-enacted One Big Beautiful Bill Act aims to reform Medicaid by eliminating certain financial incentives, imposing work requirements on certain adult beneficiaries, and requiring states to increase patient cost-sharing amounts for certain services. We cannot predict with any assurance the ultimate effect of these reforms on our business.

If our customers continue to face prolonged periods of rising interest rates, capital budget constraints, volatility, uncertainty, staffing shortages, cash flow challenges, rising costs and other financial pressures, whether due to general macroeconomic conditions, evolving policy changes under the current administration (including trade policy developments, reductions in government reimbursement or shifts in healthcare policy), cybersecurity events or other factors, it could ultimately adversely impact our ability to expand existing customer relationships or attract new customers of Tablo, timely collect amounts due, effectively manage our inventory levels, and have a material adverse effect on our bookings, revenues, results of operations, financial condition, and, ultimately, our future growth and profitability.

Litigation and other legal proceedings may adversely affect our business.

From time to time we may become involved in legal proceedings relating to patent and other intellectual property matters, product liability claims, employee claims, tort or contract claims, federal regulatory investigations, securities class action and other 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. For example, on August 29, 2024 and October 18, 2024, two purported stockholder class action lawsuits were filed against the Company, our Chief Executive Officer, then-Chief Financial Officer and prior Chief Financial Officer, in the U.S. District Court for the Northern District of California alleging that the defendants violated federal securities laws by making false or misleading statements about our business, operations and prospects related to the sale and marketing of the Tablo Hemodialysis System and TabloCart with Prefiltration, including concerning the impact of certain FDA processes for these products on our revenue growth. Further, on November 29, 2024, April 28, 2025, May 8, 2025 and June 16, 2025 Outset stockholders purporting to act on behalf of the Company filed lawsuits in the U.S. District Court for the Northern District of California against current and former members of our Board of Directors and certain of our officers, alleging that the defendants breached their fiduciary duties to the Company in connection with the same alleged events and alleged materially false and misleading statements asserted in the stockholder class action lawsuits. For more information, see the section entitled “Litigation” in Note 6, Commitments and Contingencies, to our unaudited condensed financial statements included in this Quarterly Report. Litigation is inherently unpredictable and can result in excessive or unanticipated verdicts and/or injunctive relief that affect how we operate our business. We could incur judgments or enter into settlements of claims for monetary damages or for agreements to change the way we operate our business, or both. There may be an increase in the scope of these matters or there may be additional lawsuits, claims, proceedings or investigations in the future, which could have a material adverse effect on our business, financial condition and results of operations. Adverse publicity about regulatory or legal action against us could damage our reputation and brand image, undermine our customers’ confidence and reduce long-term demand for Tablo, even if the regulatory or legal action is unfounded or not material to our operations.
