Organization and Basis of Presentation	Organization and Basis of Presentation Description of Business Crinetics Pharmaceuticals Inc. (the “Company”) is a pharmaceutical company committed to transforming the treatment of endocrine diseases and endocrine-related tumors through science rooted in patient needs. The Company is focused on discovering, developing, and commercializing novel therapies, with core expertise in targeting G protein coupled receptors with small molecules that have specifically tailored pharmacology and properties. The Company’s lead product, PALSONIFY™ (paltusotine), is the first once-daily, oral treatment approved by the U.S. Food and Drug Administration (“FDA”) for the treatment of adults with acromegaly who had an inadequate response to surgery and/or for whom surgery is not an option. Paltusotine is also in clinical development for carcinoid syndrome associated with neuroendocrine tumors (“NETs”). Our pipeline of disclosed programs includes late-stage investigational candidate atumelnant, which is currently in development for congenital adrenal hyperplasia and ACTH-dependent Cushing’s syndrome, and CRN09682, a nonpeptide drug conjugate candidate that is being developed to treat somatostatin receptor type 2 (“SST2”) expressing NETs and other SST2 expressing solid tumors. Additional discovery programs address a variety of endocrine conditions such as NETs, Graves’ disease (including Graves’ hyperthyroidism and Graves’ orbitopathy, or Thyroid Eye Disease), polycystic kidney disease, hyperparathyroidism, diabetes, obesity, and GPCR-targeted oncology indications. Liquidity From inception, the Company has devoted substantially all of its efforts to drug discovery and development, conducting preclinical studies and clinical trials, and building the infrastructure necessary for commercial operations. The Company has a limited operating history and the sales and income potential of the Company’s business and market are unproven. While the Company has received FDA approval for its lead product, the Company may continue to incur substantial operating losses even as it generates revenue from PALSONIFY, and a successful transition to attaining profitable operations is dependent upon achieving a level of revenue adequate to support the Company’s cost structure. The Company has experienced net losses and negative cash flows from operating activities since its inception and has an accumulated deficit of $1.4 billion as of December 31, 2025. As of December 31, 2025, the Company had $1.0 billion in cash, cash equivalents and investment securities, which the Company believes is sufficient to meet its funding requirements for at least the next 12 months. On January 8, 2026, the Company completed an underwritten public offering of 8,763,000 shares of its common stock for net proceeds of approximately $380.0 million, after underwriting discounts, commissions and other offering costs. The Company’s future long-term liquidity requirements will be substantial and will depend on many factors, including the Company’s ability to effectively commercialize PALSONIFY and other product candidates. The Company expects to continue to incur net losses for the foreseeable future and may need to raise substantial additional capital to accomplish its business objectives over the next several years. The Company plans to continue to fund its losses from operations and capital funding needs through a combination of its existing capital resources, product sales, equity offerings, debt financings or other sources, including potential collaborations, licenses and other similar arrangements. If the Company is not able to secure adequate additional funding, the Company may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible, or suspend or curtail planned programs. Any of these actions could materially harm the Company’s business, results of operations and prospects. There can be no assurance as to the availability or terms upon which such financing and capital might be available in the future.
