Critical Audit Matter

3 unchanged sentences

Accrued research and development expenses

Description of the Matter As described in Note 2 to the consolidated financial statements under the caption “Research and development expenses and accrued research and development”, the Company records the cost of research and development activities as they are incurred.

The Company estimates preclinical studies and clinical trial expenses based on the services performed pursuant to contracts with research institutions and clinical research organizations that conduct and manage preclinical studies and clinical trials on the Company’s behalf.

Service fees are accrued based on the Company’s estimates of the time period over which services will be performed and the level of effort to be expended in each period.

These estimates are based on communications with the third-party service providers, the Company’s estimates of accrued expenses and on information available at each balance sheet date.

As of December 31, 2021, the Company’s accrued clinical trial liability was $0.8 million.

Auditing the Company’s accrual for research and development expenses was challenging because of the estimation involved in determining the accrual balance, which included information that was accumulated from multiple sources.

Description of the Matter

As described in Note 2 to the financial statements under the caption “Research and development expenses and accrued research and development”, the Company records the cost of research and development activities as they are incurred.

Service fees are accrued based on the Company’s estimates of the time period over which services will be performed and the level of effort to be expended in each period.

These estimates are based on communications with the third-party service providers, the Company’s estimates of accrued expenses and on information available at each balance sheet date.

As of December 31, 2022, the Company’s accrued clinical trial liability was $2.2 million.

In certain circumstances, the determination of the nature and level of services that have been received during the reporting period requires judgment because the timing and pattern of vendor invoicing did not correspond to the level of services provided and invoicing from clinical study sites and other vendors may not yet be available to management.

How We Addressed the Matter

in Our Audit To test the accrued research and development expenses, our audit procedures included, among others, testing the completeness and accuracy of the underlying data used in the estimate, including, but not limited to, estimated project duration, research and manufacturing services incurred to date and terms of contractual arrangements.

To test the accrued research and development expenses, our audit procedures included, among others, testing the completeness and accuracy of the underlying data used in the estimate, including, but not limited to, estimated project duration, research and manufacturing services incurred to date and terms of contractual arrangements.

To assess the reasonableness of the data, we corroborated the progress of the clinical trials with Company research and development personnel and obtained third-party evidence supporting the activities performed to date.

We recalculated the accrual based on executed contracts with the clinical research organizations, contract manufacturing organizations, clinical study sites and collaboration partners.

We also tested subsequent invoicing received from third parties to assess the impact to the accrual at the balance sheet date and compared that to the Company’s estimates.

Tempest Therapeutics, Inc.

(“Tempest,” or the “Company”) is a clinical-stage oncology company advancing small molecules that combine both tumor-targeted and immune-mediated mechanisms with the potential to treat a wide range of tumors.

The company’s two clinical programs are TPST-1120 and TPST-1495, antagonists of PPARα and EP2/EP4, respectively.

Both TPST-1120 and TPST-1495 are advancing through Phase 1 clinical trials designed to study both agents as monotherapies and in combination with other approved agents.

In collaboration with F.

Hoffmann La Roche, TPST-1120 is also advancing through a randomized first line, global, Phase 1b/2 clinical study in combination with the standard-of-care regimen of atezolizumab and bevacizumab in patients with advanced or metastatic hepatocellular carcinoma.

Tempest is also developing an orally-available inhibitor of TREX-1 designed to activate selectively the cGAS/STING pathway, an innate immune response pathway important for the development of anti-tumor immunity.

Tempest is headquartered in South San Francisco.

and EP2/EP4, respectively.

Both programs are advancing through clinical trials designed to study the agents as monotherapies and in combination with other approved agents.

Tempest is also developing an orally available inhibitor of TREX-1, a target that controls activation of the cGAS/STING pathway.

Tempest is headquartered in Brisbane, California.

Merger with Millendo —On March 29, 2021, TempestTx, Inc.

(“Private Tempest”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Millendo Therapeutics, Inc.

(“Millendo”).

Concurrent with the execution and delivery of the Merger Agreement, Private Tempest entered into funding agreements with certain investors named therein, pursuant to which the investors agreed to purchase, in the aggregate, $ 30.0 million of common stock of Private Tempest, convertible into securities of Millendo.

1 unchanged sentence

Prior to the effective time of the merger, Millendo effected a 1-for-15 reverse stock split, and right after the merger, Millendo changed its name to Tempest Therapeutics, Inc.

Under the terms of the Merger Agreement, immediately prior to the effective time of the merger, each share of Private Tempest’s preferred stock was converted into a share of Private Tempest’s common stock.

At closing of the merger, the Company issued an aggregate of approximately 5,365,899 shares of its common stock to Private Tempest stockholders, based on an exchange ratio of 0.0322 shares of the Company’s common stock for each share of Private Tempest common stock outstanding immediately prior to the merger, including those shares of common stock issued upon conversion of the Private Tempest preferred stock, resulting in approximately 6,635,345 shares of the Company’s common stock being issued and outstanding immediately following the effective time of the merger.

The Company also assumed all of the outstanding and unexercised stock options and warrants to purchase shares of Private Tempest capital stock.

The assumed options continue to be governed by the terms of the 2011 and 2017 Equity Incentive Plans (as discussed more in Note 12) under which the options were originally granted, with such options hence forth representing the right to purchase a number of shares of the Company’s common stock equal to 0.0322 multiplied by the number of shares of Private Tempest common stock previously represented by such options.

The assumed options continue to be governed by the terms of the 2011 and 2017 Equity Incentive Plans (as discussed more in Note

9) under which the options were originally granted, with such options hence forth representing the right to purchase a number of shares of the Company’s common stock equal to 0.0322 multiplied by the number of shares of Private Tempest common stock previously represented by such options.

The merger was accounted for as a reverse recapitalization in accordance with U.S.

generally accepted accounting principles (“GAAP”).

Under this method of accounting, Private Tempest was deemed to be the accounting acquirer for financial reporting purposes.

(ii) Private Tempest would designate a substantial majority of the initial members of the board of directors of the combined company;

(iii) Private Tempest’s executive management team would become the management of the combined company;

and (iv) the combined company would be named Tempest Therapeutics, Inc.

Accordingly, for accounting purposes, the merger was treated as the equivalent of Tempest issuing stock to acquire the net assets of Millendo.

As a result of the merger, the net assets of Millendo were recorded at their acquisition-date fair value in the financial statements of Private Tempest and the reported operating results prior to the merger will be those of Private Tempest.

The accompanying financial statements have been prepared assuming the Company will continue as a going concern.

In the course of its development activities, t he Company had incurred losses since inception and had forecasted cash needs in excess of current liquidity as of December 31, 2020, which raised substantial doubt about its ability to continue as a going concern at that time.

Management implemented a plan to remove this condition by raising additional capital.

In January 2021, the Company entered into a loan agreement with a lender to borrow a term loan amount of $35.0 million of which $15.0 million was funded to the Company on January 15, 2021 (see Note 8).

In addition, as a result of the merger with Millendo, the Company raised an additional $30.0 million.

In July 2021, the Company also entered into a sales agreement (the “Sales Agreement”) with Jefferies LLC (the “Agent”), pursuant to which the Company may sell, from time to time, up to an aggregate sales price of $100.0 million of its common stock through the Agent in a series of one or more ATM equity offerings .

The additional capital will fund the Company’s ongoing working capital, investing, and financing requirements for at least the next 12 months.

The Company has incurred operating losses since inception.

As of December 31, 2022, we had cash and cash equivalents of $ 31.2 million.

Our ability to fund continued development will require additional capital, and we intend to raise such capital through the issuance of additional debt or equity including in connection with potential merger opportunities, or through business development activities.

Our ability to continue as a going concern is dependent upon our ability to successfully accomplish these plans and secure sources of financing and ultimately attain profitable operations.

If we are unable to obtain adequate capital, we could be forced to cease operations.

On April 29, 2022, the Company completed a private investment in public equity (“PIPE”) financing from the sale of 3,149,912 shares of its common stock at a price per share of $ 2.36 and, and in lieu of shares of common stock, pre-funded warrants to purchase up to 3,206,020 shares of its common stock at a price per pre-funded warrant of $ 2.359 to EcoR1 Capital, LLC and Versant Venture Capital (the “PIPE Investors”).

Net proceeds from the PIPE financings totaled approximately $ 14.5 million, after deducting offering expenses.

The Company entered into a registration rights agreement (the “Registration Rights Agreement”) with the PIPE Investors pursuant to which the Company filed a registration statement with the SEC registering the resale of the 3,149,912 shares common stock and the 3,206,020 shares of common stock underlying the pre-funded warrants issued in the PIPE financing.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation —The accompanying Consolidated Financial Statements have been prepared in accordance with US generally accepted accounting principles ("GAAP") and necessarily include amounts based on estimates and assumptions by management.

Use of Estimates —The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period.

On an ongoing basis, the Company evaluates its estimates and assumptions, including those related to research and development accruals, recoverability of long-lived assets, right-of-use assets, lease obligations, stock-based compensation and income taxes uncertainties and valuation allowances.

1 unchanged sentence

Actual results may differ from those estimates.

Segment Information —The Company operates and manages its business as one reportable and operating segment, which is the business of discovery and development of small molecule drugs to treat cancers.

All assets and operations are in the U.S.

The Company’s Chief Executive Officer, who is the chief operating decision maker, reviews financial information on an aggregate basis for purposes of allocating resources and evaluating financial performance.

Risks and Uncertainties —The Company is subject to risks and uncertainties common to early-stage companies in the biotechnology industry, including, but not limited to, development by competitors of new technological innovations, protection of proprietary technology, dependence on key personnel, reliance on single-source vendors, availability of raw materials, patentability of the Company’s products and processes and clinical efficacy and safety of the Company’s products under development, compliance with government regulations and the need to obtain additional financing to fund operations.

Product candidates currently under development will require significant additional research and development efforts, including extensive preclinical studies, clinical trials and regulatory approval, prior to commercialization.

These efforts will require significant amounts of additional capital, adequate personnel infrastructure and extensive compliance and reporting.

The Company’s product candidates are still in development and, to date, none of the Company’s product candidates have been approved for sale and, therefore, the Company has not generated any revenue from product sales.

There can be no assurance that the Company’s research and development will be successfully completed, that adequate protection for the Company’s intellectual property will be obtained or maintained, that any products developed will obtain necessary government regulatory approval or that any approved products will be commercially viable.

Even if the Company’s product development efforts are successful, it is uncertain when, if ever, the Company will generate revenue from product sales.

The Company’s product

candidates are still in development and, to date, none of the Company’s product candidates have been approved for sale and, therefore, the Company has not generated any revenue from product sales.

Even if the Company’s product development efforts are successful, it is uncertain when, if ever, the Company will generate revenue from product sales.

The Company operates in an environment of rapid technological change and substantial competition from other pharmaceutical and biotechnology companies.

In addition, the Company is dependent upon the services of its employees, consultants and other third parties.

Moreover, the current COVID-19 pandemic, which is impacting worldwide economic activity, poses risk that the Company or its employees, contractors, suppliers, and other partners may be prevented from conducting business activities for an indefinite period of time, including due to shutdowns that may be requested or mandated by governmental authorities.

The extent to which the COVID-19 pandemic will impact the Company’s business will depend on future developments that are highly uncertain and cannot be predicted at this time.

Concentration of Credit Risk —Financial instruments, which potentially subject the Company to concentration of risk, consist principally of cash and money market fund.

All of the Company’s cash and money market fund are deposited in accounts with a major financial institution, and amounts may exceed federally insured limits.

Management believes that the Company is not

exposed to significant credit risk due to the financial strength of the depository institution in which the cash and money market fund are held.

Concentration of Credit Risk —Financial instruments, which potentially subject the Company to concentration of risk, consist principally of cash and money market fund.

All of the Company’s cash and money market fund are deposited in accounts with a major financial institution in excess of federally insured limits.

The Company is exposed to credit risk in the event of default by the financial institutions holding its cash and cash equivalents to the extent recorded in the balance sheets.

While the Company has not experienced any losses in such accounts, the recent failure of Silicon Valley Bank (SVB), at which the Company held cash and cash equivalents in multiple accounts, exposed the Company to significant credit risk prior to the completion by the Federal Deposit Insurance Corporation of the resolution of SVB in a manner that fully protected all depositors.

The Company had subsequently transferred its accounts to one or more alternate depository institutions.

The Company has no off-balance sheet concentrations of credit risk, such as foreign currency exchange contracts, option contracts or other hedging arrangements.

Cash and Cash Equivalents —The Company considers all highly liquid investments purchased with original maturities of 90 days or less at acquisitions to be cash equivalents.

As of December 31, 2021 and 2020, the Company’s cash and cash equivalents consisted of bank deposits and money market funds.

Leases —The Company determines if an arrangement is a lease at contract inception.

Cash and Cash Equivalents —The Company considers all highly liquid investments purchased with original maturities of 90 days or less at acquisitions to be cash equivalents.

As of December 31, 2022 and 2021 , the Company’s cash and cash equivalents consisted of bank deposits and money market funds.

Leases —The Company determines if an arrangement is a lease at contract inception.

A lease exists when a contract conveys to the customer the right to control the use of identified property, plant, or equipment for a period of time in exchange for consideration.

7 unchanged sentences

Lease expense for lease payments is recognized on a straight-line basis over the lease term.

Property and Equipment —Property and equipment is recorded at cost and depreciated over the estimated useful lives of the related assets using the straight-line method.

Upon disposal of an asset, the related cost and accumulated depreciation are removed from the asset accounts and any resulting gain or loss is included in the consolidated statements of operations.

Repair and maintenance costs are expensed as incurred, whereas major improvements are capitalized as additions to property and equipment.

The estimated useful lives of the Company’s respective assets are as follows:

Computer equipment and software 3 years

Furniture and fixtures 7 years

Laboratory equipment 5 years

Leasehold improvements Shorter of the useful life of the asset or the life of the lease

Impairment of Long-Lived Assets —Long-lived assets are reviewed for impairment if events or circumstances indicate the carrying amount of these assets may not be recoverable.

If this review indicates that these assets will not be recoverable, based on the forecasted undiscounted future operating cash flows expected to result from the use of long-lived assets and their eventual disposition, the Company’s carrying value of the long-lived assets is reduced to fair value based on a discounted future cash flow approach or quoted market values.

Prior to the merger, the grant date fair market value of the shares of common stock underlying stock options had historically been determined by the Company’s Board of Directors.

Up until the merger, there had been no public market for the Company’s common stock, and therefore the Board of Directors exercised reasonable judgment and considered a number of objective and subjective factors to determine the best estimate of the fair market value, which included valuations performed by an independent third-party, important developments in the Company’s operations, sales of convertible preferred stock, actual operating results, financial performance, the conditions in the life sciences industry, the economy in general, the stock price performance and volatility of comparable public companies, and the lack of liquidity of the Company’s common stock.

Prior to the merger, the grant date fair market value of the shares of common stock underlying stock options has historically been determined by the Company’s Board of Directors.
