Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Crinetics Pharmaceuticals, Inc. (the “Company”) as of December 31, 2024 and 2023, the related consolidated statements of operations and comprehensive loss, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2024, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company's internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) and our report dated February 27, 2025 expressed an unqualified opinion thereon.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Clinical Trial Accruals

As described in Notes 2 and 5 to the consolidated financial statements, clinical trial activities are accrued and expensed based on estimates of the period in which services and efforts provided by contract research organizations (“CROs”) and other third parties. Estimates are determined by reviewing cost information provided by CROs, other third-party vendors and internal clinical personnel, and contractual arrangements with CROs and the scope of work to be performed. As of December 31, 2024, the Company recorded $3.1 million in clinical trial accruals, which was included in accounts payable and accrued expenses on the consolidated balance sheet.

We identified the estimation of clinical trial accruals as a critical audit matter. Management’s judgment was required in estimating the progress of services and the associated costs incurred used to determine the accrued liabilities for clinical trial expenses. Auditing clinical trial accruals was especially challenging due to the nature and extent of audit effort required to address the matter.

The primary procedures we performed to address this critical audit matter included:

•

Testing management’s process for estimating clinical trial accruals by: (i) obtaining and inspecting certain agreements and amendments and (ii) confirming total clinical costs incurred and total amounts billed with certain third-party vendors.

•

Testing the completeness of the Company’s clinical trial accruals by: (i) evaluating internal materials and publicly available information (such as press releases and public databases that track clinical trials) and (ii) testing invoices received after year-end for certain third-party vendors.
