Crinetics Pharmaceuticals Inc

1. ORGANIZATION AND BASIS OF PRESENTATION

Description of Business

Crinetics Pharmaceuticals, Inc. (the “Company”) is a clinical-stage pharmaceutical company incorporated in Delaware on November 18, 2008 and based in San Diego, California. The Company is focused on the discovery, development and commercialization of novel therapeutics for rare endocrine diseases and endocrine-related tumors. In January 2017, the Company established a wholly-owned Australian subsidiary, Crinetics Australia Pty Ltd (“CAPL”), in order to conduct various preclinical and clinical activities for its development candidates. In September 2024, the Company established Crinetics Pharmaceuticals Europe GmbH ("CPEG"), a wholly-owned Swiss subsidiary which was formed, among other things, to conduct various development, regulatory and pre-commercialization activities for our product candidates in Europe.

Our lead product candidate is paltusotine, which is in clinical development for the treatment of acromegaly and carcinoid syndrome associated with neuroendocrine tumors, or NETs. Our second product candidate is atumelnant (formerly CRN04894), which is in clinical development for congenital adrenal hyperplasia, or CAH, and patients with either Cushing's disease or Ectopic ACTH Syndrome, or EAS.

Principles of Consolidation and Foreign Currency Transactions and Translations

The consolidated financial statements include the accounts of the Company, CAPL, and CPEG. All intercompany accounts and transactions have been eliminated in consolidation.

The functional currency of CAPL is the U.S. dollar. Assets and liabilities that are not denominated in the functional currency are remeasured into U.S. dollars at foreign currency exchange rates in effect at the balance sheet date except for nonmonetary assets, which are remeasured at historical foreign currency exchange rates in effect at the date of transaction. Net realized and unrealized gains and losses from foreign currency transactions and remeasurement are reported in other income (expense), in the accompanying consolidated statements of operations and comprehensive loss and were not material for all periods presented.

The functional currency of CPEG is the Swiss Franc. Assets and liabilities from CPEG are translated at the exchange rate at the balance sheet date while financial statement elements representing revenues, expenses, gains, and losses are translated at the using a weighted average exchange rate. The resulting translation adjustments are recorded as a component of other comprehensive income or loss and have been immaterial to date.

Liquidity

From inception, the Company has devoted substantially all of its efforts to drug discovery and development and conducting preclinical studies and clinical trials. The Company has a limited operating history and the sales and income potential of the Company’s business and market are unproven. Successful transition to attaining profitable operations is dependent upon achieving a level of revenues 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 $952.1 million as of December 31, 2024.

As of December 31, 2024, the Company had$1.4 billionin unrestricted cash, cash equivalents and investment securities, which the Company believes is sufficient to meet its funding requirements for at least the next 12 months.

The Company expects to continue to incur net losses for the foreseeable future and believes it will need to raise substantial additional capital to accomplish its business plan over the next several years. The Company plans to continue to fund its losses from operations and capital funding needs through a combination of 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.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

The Company’s consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). The preparation of the Company’s consolidated financial statements requires it to make estimates and assumptions that impact the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities in the Company’s consolidated financial statements and accompanying notes. The most significant estimates in the Company’s consolidated financial statements relate to accrual of research and development expenses, valuation of stock-based awards, fair values of financial instruments, revenue recognition, and the assumptions underlying the determination of the estimated incremental borrowing rate for the determination of the Company’s operating lease right-of-use assets. Estimates are based on historical experiences or on forecasts, including information received from third parties and various other factors that the Company believes are reasonable under the circumstances. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. Actual results could differ from those estimates.

Investment in Radionetics

In October 2021, the Company, together with other investors, announced the formation of Radionetics Oncology, Inc. ("Radionetics").

The Company first analyzes its investment in another entity to determine if the entity is a variable interest entity (“VIE”) and if so, whether the Company is the primary beneficiary requiring consolidation. An entity is considered a VIE if (1) the entity does not have enough equity to finance its own activities without additional support, (2) the entity’s at-risk equity holders lack the characteristics of a controlling financial interest, or (3) the entity is structured with non-substantive voting rights. VIEs are consolidated by the primary beneficiary, which is the entity that has both the power to direct the activities that most significantly impact the VIE’s economic performance and the obligation to absorb losses or the right to receive benefits from the VIE that potentially could be significant to the VIE. Variable interests in a VIE can be contractual, ownership, or other financial interests. The Company re-assesses its investment upon reconsideration events to determine whether the Company is the primary beneficiary of the VIE, in which case the Company would consolidate the VIE.

If it has been determined that the Company is not the primary beneficiary but does have the ability to exercise significant influence over the VIE, the Company accounts for the unconsolidated investment under the equity method of accounting.

Fair Value Measurements

The accounting guidance defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or non-recurring basis. Fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the accounting guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level 1: Observable inputs such as quoted prices in active markets.

Level 2: Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly.

Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions about risk and the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances.

The carrying amounts of the Company’s current financial assets, restricted cash and current financial liabilities are considered to be representative of their respective fair values because of the short-term nature of those instruments. The Company recorded the derivative asset (see "Note 9") and investment securities (see "Note 4") at fair value.

Cash, Cash Equivalents and Restricted Cash

Cash and cash equivalents include cash held in readily available checking and money market accounts, as well as short-term debt securities with maturities of three months or less when purchased. Restricted cash represents cash held as collateral for the Company’s facility leases and is reported as a long-term asset in the accompanying consolidated balance sheets. Cash and cash equivalents are considered Level 1 investments.

Investment Securities

Our investment in debt securities have been classified as “available-for-sale” and are carried at fair value as determined based upon quoted market prices or pricing models for similar securities at period end. Investments with contractual maturities less than 12 months at the balance sheet date are considered short-term investments. Investments with contractual maturities beyond one year are also classified as short-term due to the Company’s ability to liquidate the investment for use in operations within the next 12 months.

The Company elected the practical expedient to exclude the applicable accrued interest from both the fair value and amortized costs basis of available-for-sale securities for purposes of identifying and measuring an impairment. Accrued interest receivable on available-for-sale securities is recorded in prepaid expenses and other current assets in the accompanying consolidated balance sheets. The Company’s accounting policy is to not measure an allowance for credit loss for accrued interest receivable and to write-off any uncollectible accrued interest receivable as a reversal of interest income in a timely manner, which the Company considers to be in the period in which the Company determines the accrued interest will not be collected.

Realized gains and losses on investment securities are derived using the specific identification method for determining the cost of securities sold and are included in other income (expenses), net in the accompanying consolidated statements of operations and comprehensive loss. The Company has not realized any significant gains or losses on sales of available-for-sale debt securities during any of the periods presented. Interest income is recognized when earned and is included in interest income in the accompanying consolidated statements of operations and comprehensive loss, as are the amortization of purchase premiums and accretion of purchase discounts on investment securities.

Effective January 1, 2023, at each balance sheet date, the Company assesses available-for-sale debt securities in an unrealized loss position to determine whether the unrealized loss or any potential credit losses should be recognized in net loss. For available-for-sale debt securities in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more likely than not that it will be required to sell, the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through net loss. For available-for-sale securities that do not meet the criteria, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, the Company considers the severity of the impairment, any changes in interest rates, underlying credit ratings, and forecasted recovery, among other factors. The credit-related portion of unrealized losses, and any subsequent improvements, are recorded as an allowance in interest income. There have been no impairment or credit losses recognized during the periods presented in the accompanying consolidated statements of operations and comprehensive loss. Unrealized gains and losses that are not credit-related are included in accumulated other comprehensive loss in theaccompanying consolidated balance sheets.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents and investment securities. The Company maintains deposits in federally insured financial institutions in excess of federally insured limits. The Company has not experienced any losses in such accounts and believes it is not exposed to significant risk on its cash balances due to the financial position of the depository institution in which those deposits are held. Additionally, the Company has established guidelines regarding approved investments and maturities of investments, which are designed to maintain safety and liquidity.

Leases

The Company determines if an arrangement is a lease at the inception of the arrangement. Short-term leases with an initial term of 12 months or less are not recorded on the balance sheets. Leases with a term longer than 12 months that are determined to be operating leases are included in operating lease right-of-use assets, operating lease liabilities and noncurrent operating lease liabilities in the consolidated balance sheets at the accounting commencement date of the arrangement. The Company accounts for each separate lease and non-lease component as a single lease component. When the Company’s leases do not provide an implicit rate, an incremental borrowing rate is used based on the information available at accounting commencement dates in determining the present value of lease payments. The incremental borrowing rate is the rate of interest that the Company would expect to pay to borrow over a similar term, and on a collateralized basis, an amount equal to the lease payments in a similar economic environment. The Company’s lease terms may include options to extend or terminate the lease when the Company is reasonably certain that it will exercise such options. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Lease agreements may contain variable costs such as common area maintenance, insurance, taxes or other costs. Such variable lease costs are expensed as incurred. The Company assesses its leases to determine whether the arrangements contain lease incentives.

If a lease is modified, the modified contract is evaluated to determine whether it is or contains a lease. If a lease continues to exist, the lease modification is determined to be a separate contract when the modification grants the lessee an additional right-of-use asset that is not included in the original lease and the lease payments increase commensurate with the standalone price for the additional right-of-use asset. A lease modification that results in a separate contract will be accounted for in the same manner as a new lease. For a modification that is not a separate contract, the Company will reassess the lease classification and incremental borrowing rate using the modified terms and conditions and the facts and circumstances as of the effective date of the modification and recognize the amount of the remeasurement of the lease liability for the modified lease as an adjustment to the corresponding operating lease right-of-use asset.

Property and Equipment, Net

Property and equipment consist of leasehold improvements, and lab and various other equipment. Such assets are stated at cost and depreciated on a straight-line basis over the estimated useful life of the related assets. The Company estimates its useful lives of its lab and other equipment as follows: lab equipment –three tofive years; office equipment -threeto five years; computer and software –three years. Leasehold improvements are amortized over the shorter of the estimated useful life of the improvement or the remaining term of the associated lease.

Repairs and maintenance costs are charged to expense as incurred and expenditures that materially extend the useful lives of assets are capitalized.

Impairment of Long-Lived Assets

The Company reviews long-lived assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets (or asset group) may not be fully recoverable.

Factors considered in deciding when to perform an impairment review include significant underperformance of the business in relation to expectations, significant negative industry or economic trends, and significant changes or planned changes in the use of the assets. An impairment loss is recognized when estimated undiscounted future cash flows expected to result from the use of an asset (or asset group) are less than its carrying amount. If such assets are considered impaired, the impairment loss recognized is measured as the excess of the carrying value of the impaired asset over its fair value, determined based on future cash flows or appraised values, depending on the nature of the asset (or asset group). The Company hasnot recognized any impairment losses in any of the periods presented in these consolidated financial statements.

Revenue Recognition

The Company has generated revenue from licensing arrangements and supply agreements. The Company recognizes revenues when, or as, the promised goods or services are transferred to customers in an amount that reflects the consideration to which it expects to be entitled in exchange for those services. To determine revenue recognition for arrangements, the Company performs the following five steps: (1) identify the contract(s) with a customer; (2) identify the performance obligation(s) in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligation(s) in the contract; and (5) recognize revenue when (or as) the performance obligation(s) are satisfied. At contract inception, the Company assesses the goods or services promised within each contract, assesses whether each promised good or service is distinct and identifies those that are performance obligations. The Company recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when, or as, the performance obligation is satisfied.

The Company has entered into licensing and collaboration agreements that mainly include the following: (i) upfront considerations; (ii) payments associated with achieving certain milestones; and (iii) royalties based on specified percentages of net product sales, if any.

The Company has also entered into a manufacturing and supply arrangement that includes reimbursements of costs plus a pre-determined margin.

At the inception of a collaboration arrangement, the Company first assesses whether the contractual arrangement is within the scope of The Accounting Standards Codification ("ASC") Topic 808, Collaborative Arrangements (“ASC 808”) to determine whether the arrangement involves a joint operating activity and involves two (or more) parties that are both active participants in the activity and exposed to significant risks and rewards dependent on the commercial success of such activity. Then the Company determines whether the collaboration arrangement in its entirety represents a contract with a customer as defined by ASC Topic 606, Revenue From Contracts with Customers ("ASC 606"). If only a portion of the collaboration arrangement is potentially with a customer, the Company applies the distinct good or service unit-of-account guidance in ASC 606 to determine whether there is a unit of account that.

At the initiation of an agreement, the Company analyzes each unit of account within the contract to determine if the counterparty is a customer in the context of the unit of account.

The Company considers a variety of factors in determining the appropriate estimates and assumptions under the arrangements, such as whether the elements are distinct performance obligations, whether there are observable standalone prices, whether the license is functional or symbolic, and whether the Company is acting as the agent or principal. The Company evaluates each performance obligation to determine if it can be satisfied and recognized as revenue at a point in time or over time.

At the inception of arrangements that include milestone payments, the Company uses judgment to estimate the amount of milestone payments, which is a variable consideration, to include in the transaction price using the most likely method. If it is probable that a significant revenue reversal will not occur, then the estimated amount is included in the transaction price. Milestone payments that are not within the Company's or the licensee’s control, such as regulatory approvals, are not included in the transaction price until those approvals are received. At the end of each reporting period, the Company re-evaluates the estimated variable consideration included in the transaction price and any related constraint and, as necessary, adjusts the estimate of the overall transaction price. Any adjustments will be recorded on a cumulative catch-up basis, which would affect revenues and earnings in the period of adjustment.

The Company develops estimates of the standalone selling price for each distinct performance obligation. Variable consideration that relates specifically to efforts to satisfy specific performance obligations is allocated entirely to those performance obligations. Other components of the transaction price are allocated based on the relative standalone selling price, over which management has applied significant judgment. The Company determines the standalone selling price for license-related performance obligations using a market approach, which may include assumptions such as forecasted revenues, development timelines, discount rates and probabilities of success. The Company estimates the standalone selling price for the data exchange performance obligation (see "Note 8") by forecasting the expected costs of satisfying a performance obligation plus a predetermined margin.

In the case of a license that is a distinct performance obligation, the Company recognizes revenue allocated to the license from non-refundable, up-front fees at the point in time when the license is transferred to the licensee and the licensee can use and benefit from the license. For licenses that are bundled with other distinct or combined obligations, the Company uses judgment to assess the nature of the performance obligation to determine whether the performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue. If the performance obligation is satisfied over time, then the Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.

The selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. The Company has used the cost-to-cost measure of progress because it best depicts the transfer of control to the customer which occurs as the Company incurs costs. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation, which is considered an input method. The Company uses judgment to estimate the total cost of these performance obligations, which include subcontractors' costs, labor, materials, other direct costs and an allocation of indirect costs. The Company evaluates these cost estimates and the progress each reporting period and, as necessary, the Company adjusts the measure of progress and related revenue recognition.

Sales-based milestones and royalties are recognized at the later of when the subsequent sale or usage occurs or the performance obligation for which some or all of the sales-based milestones and royalties have been allocated to has been satisfied or partially satisfied.

Research and Development Expenses

Research and development (“R&D”) expenses consist primarily of salaries, payroll taxes, employee benefits and stock-based compensation for individuals involved in R&D efforts, as well as consulting expenses, third-party R&D expenses, laboratory supplies, clinical materials and overhead, including facilities and depreciation costs, offset by the Australian Tax Incentive discussed below. R&D expenses are charged to expense as incurred. Payments made prior to the receipt of goods or services to be used in R&D are capitalized until the goods or services are received and are recorded as prepaid expenses and other current assets.

Costs incurred under contracts with contract research organizations ("CROs") that conduct and manage the Company’s clinical trials are also included in R&D expenses. The financial terms and activities of these agreements vary from contract to contract and may result in uneven expense levels. Clinical trial activities are accrued and expensed based on estimates of the period in which services and efforts provided by 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. If the amounts that the Company is obligated to pay under its clinical trial agreements are modified (for instance, because of changes in the clinical trial protocol or scope of work to be performed), the

Company adjusts its accruals accordingly on a prospective basis. Revisions to contractual payment obligations are charged to expense in the period in which the facts that give rise to the revision become reasonably certain.

Australian Tax Incentive

CAPL is eligible to obtain a cash refund from the Australian Taxation Office for eligible R&D expenditures under the Australian R&D Tax Incentive Program (the “Australian Tax Incentive”). The Australian Tax Incentive is recognized as a reduction to R&D expense when there is reasonable assurance that the relevant expenditure has been incurred, the amount can be reliably measured and that the Australian Tax Incentive will be received. The Australian Taxation Office has a recapture right for a period of four years.

The Company recognized reductions to R&D expense of $43,000 and $0.8 million for the years ended December 31, 2023, and 2022, respectively. There was no reduction to R&D expense during the year ended December 31, 2024 for the Australian tax incentive.

Patent Costs

All costs incurred for the filing of patent applications are recorded as general and administrative expenses in the accompanying consolidated statements of operations and comprehensive loss when incurred, as the recoverability of these expenses is uncertain.

Stock-Based Compensation

Stock-based compensation expense represents the estimated grant date fair value of the Company’s equity awards, consisting of stock options, restricted stock units and shares issued under the Company’s Employee Stock Purchase Plan, recognized over the requisite service period of such awards (usually the vesting period) on a straight-line basis. The Company estimates the fair value of all stock option grants using the Black-Scholes option pricing model and recognizes forfeitures as they occur. Restricted stock units are valued using the grant date stock price. For stock awards for which vesting is subject to performance-based milestones, the expense is recorded over the remaining service period after the point when the achievement of the milestone is probable, or the performance condition has been achieved.

Income Taxes

The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the consolidated financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.

The Company recognizes net deferred tax assets to the extent that the Company believes these assets are more likely than not to be realized. In making such a determination, management considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If management determines that the Company would be able to realize its deferred tax assets in the future in excess of their net recorded amount, management would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.

The Company records uncertain tax positions on the basis of a two-step process whereby (1) management determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, management recognizes the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with the related tax authority. The Company recognizes interest and penalties related to unrecognized tax benefits within income tax expense, and any accrued interest and penalties would be included within the related tax liability. No such costs were recorded during the three years ended December 31, 2024.

Comprehensive Loss

Comprehensive loss is comprised of the Company’s net loss and the unrealized gains or losses on the Company’s available for sale investment securities for all periods presented. The cumulative amount of unrealized gains and losses is reflected as a separate component of stockholders' equity in the accompanying consolidated balance sheets as accumulated other comprehensive income (loss). There were no tax effects for the years ended December 31, 2024, 2023 and 2022.

Net Loss Per Share

Basic net loss per share is computed by dividing the net loss by the weighted-average number of common shares outstanding for the period, without consideration for potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock and dilutive common stock equivalents outstanding for the period determined using the treasury-stock and if-converted methods. Dilutive common stock equivalents are comprised of common stock subject to repurchase and stock options outstanding under the Company’s stock option plan. For all periods presented, there is no difference in the number of shares used to calculate basic and diluted shares outstanding as inclusion of the potentially dilutive securities on loss per share would be antidilutive.

Potentially dilutive securities (in common stock equivalent shares) not included in the calculation of diluted net loss per share because to do so would be anti-dilutive are as follows (in thousands):

Recently Adopted Accounting Pronouncements

ASU 2023-07

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280) Improvements to Reportable Segment Disclosures(“Topic 280”), which modifies the disclosure and presentation requirements of reportable segments. The amendments in the update require the disclosure of significant segment expenses that are regularly provided to the chief operating decision maker ("CODM") and included within each reported measure of segment profit and loss. The amendments also require disclosure of all other segment items by reportable segment and a description of its composition. Additionally, the amendments require disclosure of the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. Lastly, the amendment requires that a public entity that has a single reportable segment provide all the disclosures required by ASU 2023-07 and all existing segment disclosures in Topic 280. The Company adopted this standard for its 2024 annual consolidated financial statements and interim consolidated financial statements thereafter and has applied this standard retrospectively for all prior periods presented in the financial statements (see "Note 13").

Recent Accounting Pronouncements Not Yet Adopted

ASU 2023-09

In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures”. ASU 2023-09 requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid. ASU 2023-09 is effective for public entities with annual periods beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact that this guidance will have on the presentation of its consolidated financial statements and accompanying notes.

ASU 2024-03

On November 4, 2024, the FASB issued ASU 2024-03, which requires disaggregated disclosure of income statement expenses for public business entities ("PBEs"). The ASU does not change the expense captions an entity presents on the face of the income statement; rather, it requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. ASU 2024-03 is effective for all PBEs for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact that this guidance will have on the presentation of its consolidated financial statements and accompanying notes.

3. INVESTMENT SECURITIES

The Company reports its available-for-sale investment securities at their estimated fair values. The following is a summary of the available-for-sale investment securities held by the Company as of December 31, 2024 and 2023 (in thousands):

As of December 31, 2024 and 2023, available-for-sale investment securities by contractual maturity were as follows (in thousands):

The following is a summary of the available-for-sale investment securities by length of time in a net loss position as of December 31, 2024 and 2023 (in thousands):

The Company reviewed its investment holdings as of December 31, 2024 and 2023 and determined that the decrease in fair value is attributable to changes in interest rates and not credit quality, and as 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 maturity. Therefore, there wereno allowances for credit losses as of December 31,2024 and 2023. During the years ended December 31, 2024, 2023, and 2022, the Company recognized $51,000, $0, and ($86,000), respectively, of realized net gains (losses) in the accompanying statements of operations and comprehensive loss.

Accrued interest receivable on available-for-sale securities was $8.3 million and $3.1 million at December 31, 2024 and 2023, respectively. The Company did not write off any accrued interest receivable in any of the periods presented in the consolidated financial statements.

4. FAIR VALUE MEASUREMENTS

Investment Securities

The Company holds investment securities that consist of highly liquid, investment grade debt securities. The Company determines the fair value of its investment securities based upon one or more valuations reported by its investment accounting and reporting service provider. The investment service provider values the securities using a hierarchical security pricing model that relies primarily on valuations provided by an industry-recognized valuation service. Such valuations may be based on trade prices in active markets for identical assets or liabilities (Level 1 inputs) or valuation models using inputs that are observable either directly or indirectly (Level 2 inputs), such as quoted prices for similar assets or liabilities, yield curves, volatility factors, credit spreads, default rates, loss severity, current market and contractual prices for the underlying instruments or debt, and broker and dealer quotes, as well as other relevant economic measures.

Derivative Asset

On October 15, 2021, the Company received a warrant (the "Radionetics Warrant") to purchase the greater of 3,407,285 additional shares of Radionetics common stock or the number of additional shares of Radionetics common stock that would allow the Company to maintain an aggregate equity interest of 22% of the fully diluted capitalization of Radionetics. The estimated value of the Radionetics Warrant is based on valuations provided by a third-party valuation specialist using unobservable inputs due to little to no market data (Level 3 inputs).

In August 2023, the Company exercised the Radionetics Warrant to purchase 3,407,285 shares of Radionetics common stock with an exercise price of $0.00001 per share, and also cancelled its existing right to maintain an aggregate interest of 22% of the fully diluted capitalization of Radionetics. There were no material changes in the inputs or the total valuation of the Radionetics Warrant in 2023 prior to its exercise and cancellation. Upon exercise, the Radionetics Warrant of $0.7 million was derecognized (see "Note 9").

During the year ended December 31, 2022, the Company recorded $0.6 million of income in the accompanying consolidated statements of operations and comprehensive loss related to the change in value of the Radionetics Warrant.

Financial assets measured at fair value on a recurring basis as of December 31, 2024 and 2023 were as follows (in thousands):

The Company’s policy is to recognize transfers between levels of the fair value hierarchy on the date of the event or change in circumstances that caused the transfer. There wereno transfers into or out of Level 3 during the years ended December 31, 2024 and 2023.

The following is the Level 3 activity for the Company’s derivative asset:

6. OPERATING LEASES

In February 2018, the Company entered into a non-cancellable operating lease, as amended in March 2018, for a facility in San Diego, California (the "2018 Lease"). The 2018 Lease has an initial term ofseven years which expires in August 2025, and the Company has an option to extend the term of the 2018 Lease for an additional five years, a termination option subject to early termination fees and an option to sublease the facility. The 2018 Lease is subject to base lease payments and additional charges for common area maintenance and other costs and includes certain lease incentives and tenant improvement allowances. The Company’s estimated incremental fully collateralized borrowing rate of 8.0% was used in its present value calculation as the 2018 Lease does not have a stated rate and the implicit rate was not readily determinable.

In 2022, the Company entered into a lease agreement for laboratory and office space in San Diego, California (the "2022 Lease").

Under the terms of the 2022 Lease, the Company's expected future monthly minimum lease payments of $0.5 million, with six months of rent abatement in the first year, start on the earlier of (i) the date which is ten (10) months after substantial completion of demolition work, or (ii) the date of the substantial completion of improvements and first occupancy for business purposes, and the term expires on the date immediately preceding the one hundred thirty-seventh (137th) monthly anniversary of this lease payment start date. Lease payments are subject to annual 3% increases. The Company is also responsible for certain operating expenses and taxes during the term of the 2022 Lease. The 2022 Lease provides the Company with specified tenant improvement and landlord work allowances. The Company has (i) two options to extend the term of the 2022 Lease for an additional period of five (5) years each, and (ii) a right of first offer on adjacent space to the new facility, subject to the terms and conditions of the 2022 Lease. The 2022 Lease commenced in 2023 when the building was ready and available for its intended use. As of the date of the recording of the 2022 Lease, the Company is not reasonably certain that these options will be exercised. In September 2023, the Company recorded a right-of-use asset and corresponding lease liability in the accompanying consolidated balance sheets in connection with the 2022 Lease. The Company recorded $47.0 million for the Right-of-use asset obtained in exchange for the 2022 Lease.

In December 2023, the Company entered into a lease amendment to the 2022 Lease that moved the initial payment date and start of the hundred thirty-seventh month from September 2023 to November 2023. The amendment was a modification that did not result in a new contract as the modification did not provide the Company additional right-of-use assets. As a result, the Company recorded a $0.7 million reduction to right-of-use assets and lease liabilities in the accompanying consolidated balance sheets.

The Company’s estimated incremental fully collateralized borrowing rate of 8.6% was used in its present value calculation as the 2022 Lease does not have a stated rate and the implicit rate was not readily determinable. The rate was determined using a synthetic credit rating analysis.

Under the terms of the 2018 Lease and 2022 Lease, the Company provided the lessors with irrevocable letters of credit in the amounts of $0.5 million and $0.8 million, respectively, which areincluded in restricted cash and restricted cash, net of current portion, respectively, in theaccompanying consolidated balance sheets. The lessors are entitled to draw on the letters of credit in the event of any default by the Company under the terms of the leases.

As of December 31, 2024, the Company's future minimum payments under non-cancellable operating leases, were as follows (in thousands):

Operating lease cost was $8.5 million, $3.3 million, and $1.0 million for each of the years ended December 31, 2024, 2023 and 2022, respectively. As of December 31, 2024 and 2023, the Company’s weighted average remaining term was 10.1 years and 11.1 years, resp ectively. As of December 31, 2024 and 2023, the Company’s weighted-average discount rate was 8.6%.

Cash paid foramounts included in the measurement of lease liabilities for operating cash flow from operating leases was $4.5 million, $1.6 million, and $1.2 million during each of the years ended December 31, 2024, 2023 and 2022, respectively.

7. COMMITMENTS AND CONTINGENCIES

Litigation

From time to time, the Company may be subject to various claims and suits arising in the ordinary course of business. The Company does not expect that the resolution of these matters will have a material adverse effect on its financial position or results of operations.

8. REVENUE RECOGNITION

Sanwa Kagaku Kenkyusho Co., Ltd

On February 25, 2022, the Company and Sanwa Kagaku Kenkyusho Co., Ltd. ("Sanwa"), entered into a license agreement (the “Sanwa License”) whereby the Company granted Sanwa an exclusive license to develop and commercialize paltusotine in Japan.

Under the Sanwa License, Sanwa has the right to receive data obtained by the Company through certain paltusotine studies. The Company assessed the Sanwa License and concluded that Sanwa is a customer within the agreement. Sanwa will assume all costs associated with clinical trials and regulatory applications associated with these processes in Japan. Further, the Company retains all rights to develop and commercialize the product outside Japan. The Company also granted Sanwa the right to purchase supply of paltusotine for clinical and commercial requirements at cost plus a pre-negotiated percentage which was a market rate and therefore not a material right.

The Company determined that its performance obligations under the Sanwa License comprised the license and data exchange. Certain professional services, such as the Company's participation on committees, were deemed to be immaterial to the context of the contract.

In exchange, the Company received a $13.0 million nonrefundable, upfront payment and will be eligible to receive up to an additional $25.5 million in milestone payments related to the achievement of certain development, regulatory and commercial goals. In addition, upon market approval of paltusotine in Japan, the Company will be eligible to receive certain sales-based royalties. Initially, the Company deter mined that the transaction price amounted to the upfront payment of $13.0 million. During the year ended December 31, 2024, the Company achieved a $1.0 million milestone for the first indication of the development milestones and as of December 31, 2024, the Company updated its estimated transaction price to $14.0 million and recorded a cumulative catch-up adjustment of $0.4 million during year ended December 31, 2024. As there have been no sales to date, no sales-based milestones or royalties were recognized to date. Further, using the most-likely-method, the other developmental milestone payments continue to be considered fully constrained.

The control of the license was transferred to Sanwa at the inception of the contract and the Company does not have an ongoing performance obligation to support or maintain the licensed intellectual property. Revenue allocated to the data exchange obligation is recognized over time using the cost-to-cost measure as this method represents a faithful depiction of progress toward the ongoing paltusotine studies in the U.S. and related data transfer. Revenue is recognized on a gross basis as the Company is the principal.

Deferred revenue consisted of the following (in thousands):

During the years ended December 31, 2024 , 2023, and 2022, $0.9 million, $1.5 million, and $4.7 million, respectively, of the $14.0 million estimated transaction price was recognized as revenues in the accompanying consolidated statements of operations and comprehensive loss. Deferred revenues are expected to be recognized over the duration of certain paltusotine studies conducted by the Company.

On June 14, 2022, the Company and Sanwa, entered into a clinical supply agreement (the "Sanwa Clinical Supply Agreement") whereby the Company is responsible for manufacturing and supplying certain materials to Sanwa for specified activities under the Sanwa License. During the years ended December 31, 2024, 2023 and 2022, the Company recognized $0.1 million, $0.4 million, and $0.1 million respectively, of revenues from the Sanwa Clinical Supply Agreement in the accompanying consolidated statements of operations and comprehensive loss.

Cellular Longevity, Inc., doing business as Loyal

On March 24, 2023, the Company and Cellular Longevity Inc., doing business as Loyal ("Loyal") entered into a license agreement (the “Loyal License”) whereby the Company granted Loyal an exclusive license to develop and commercialize CRN01941, a somatostatin receptor type 2 agonist, for veterinary use. In exchange the Company received a $0.1 million nonrefundable, upfront payment and preferred stock in Loyal valued at approximately $2.0 million. The Company will also beeligible to receive certain single-digit sales-based royalties if the licensed intellectual property is approved for veterinary use.

No revenue was recognized during the year ended December 31, 2024. During the year ended December 31, 2023, the Company recognized $2.1 million of revenues from the Loyal License at the inception of the contract in the accompanying consolidated statements of operations and comprehensive loss. As of December 31, 2024, the shares of Loyal preferred stock issued and to be issued to the Company valued at $2.0 million is included in other assets in the accompanying consolidated balance sheets. The Loyal preferred stock does not have a readily determinable fair value and is recorded at cost less impairment. The Company assesses equity securities without a readily determinable fair value for changes in observable prices each period, noting none for theyear ended December 31, 2024.

9. INVESTMENT IN RADIONETICS

Investment in Radionetics

In October 2021, the Company entered into a Collaboration and License Agreement (the "Radionetics License") with Radionetics Oncology, Inc. ("Radionetics"), in which the Company granted Radionetics an exclusive worldwide license to its technology for the development of radiotherapeutics and related radio-imaging agents in exchange for 50,500,000 shares of common stock of Radionetics, which represented an initial majority stake in Radionetics of 64%, and a warrant (the "Radionetics Warrant") to purchase the greater of 3,407,285 additional shares of Radionetics common stock or the number of additional shares of Radionetics common stock that would allow the Company to maintain an aggregate equity interest of 22% of the fully diluted capitalization of Radionetics.

Radionetics is a variable interest entity ("VIE") due to having insufficient equity to finance its activities without additional subordinated financial support. The Company evaluated whether it is the primary beneficiary of Radionetics by evaluating Radionetics’ key activities: (1) conducting research and development, (2) making financing decisions, and (3) determining the strategic direction of Radionetics. Decisions about research and development activities are made by unanimous vote of members of the research and development committee, in which no individual party has unilateral decision-making power. Decisions about financing and strategic direction rest with Radionetics’ board of directors, and no party was determined to be in control, given the Radionetics board of directors was comprised of three members for which each of Crinetics, 5AM Ventures ("5AM") and Frazier Healthcare Partners ("Frazier") were entitled to appoint and replace, as needed, their board designee, and a fourth member mutually agreed upon by the other three board members. Radionetics’ management was separate from the Company and was determined by Radionetics’ board of directors. As the Company did not control any of Radionetics' key activities, it was not the primary beneficiary of the VIE and did not consolidate the financial results of Radionetics.

The Company accounts for its investment in Radionetics common stock under the equity method of accounting due to its ability to exercise significant influence. The Company records its share of Radionetics income (loss) outside of operations in the statements of operations and comprehensive loss on a quarterly lag. The Company's equity method investment in Radionetics was written down to zero during the first quarter of 2022 as a result of the allocation of the Company’s share of losses of the investee.

In August 2023, Radionetics completed a refinancing that included a number of transactions that were negotiated by the Company as a package (the “August 2023 Radionetics Transaction”). In connection with the August 2023 Radionetics Transaction, (1) the Company exercised the Radionetics Warrant to purchase 3,407,285 shares of Radionetics common stock with an exercise price of $0.00001 per share, (2) the Company exchanged 32,344,371 shares of Radionetics common stock for Radionetics preferred stock on a one-for-one basis, (3) the Company invested $5.0 million to purchase 14,404,656 shares of preferred stock in Radionetics along with other new and existing investors who participated in the financing, and (4) the Company and Radionetics agreed to amend the Radionetics License to include additional sales milestones of up to $15 million. Radionetics’ convertible notes held by other investors were also converted to Radionetics preferred stock and certain Radionetics common shares held by other investors were cancelled in connection with the August 2023 Radionetics Transaction.

The August 2023 Radionetics Transaction was a VIE reconsideration event. The Company determined that Radionetics continues to be a VIE due to Radionetics having insufficient equity to finance its activities without additional subordinated financial support. The Company also reevaluated whether it is the primary beneficiary of Radionetics and noted there were no changes to Radionetics’ key activities or the conclusion that the Company does not control any of these activities. The size of Radionetics’ board of directors was increased from four to six members. Crinetics, 5AM and Frazier are each entitled to appoint and replace, as needed, their board designee, the fourth member is Radionetics’ CEO, and the fifth and sixth members must be mutually agreed upon by the other four board members. All changes to board composition are subject to shareholder approval with common and preferred shareholders having equal votes. Radionetics’ management continues to be entirely separate from the Company and determined by the Radionetics’ board of directors. As the Company does not control any of Radionetics' key activities, it is not the primary beneficiary and does not consolidate the financial results of Radionetics. Accordingly, the Company continues to account for its investment in Radionetics under the equity method of accounting due to its ability to exercise significant influence.

The Company determined that its preferred stock investment in Radionetics represents in-substance common stock. The preferred stock investment is substantially similar to common stock in that it does not have a substantive liquidation preference since the preferred stock will participate in substantially all of Radionetics losses, the conversion ratio for preferred stock into common stock is on a one-for-one basis without any significant restrictions or contingencies, and the preferred stock lacks redemption features, among other factors.

The Company is not obligated to fund losses incurred by Radionetics. The Company’s $5.0 million purchase of preferred stock in the August 2023 Radionetics Transaction was alongside new and existing investors and did not fund previous losses.

In connection with the August 2023 Radionetics Transaction, the Company exercised the Radionetics Warrant, which had a fair value of $0.7 million, and purchased $5.0 million of preferred stock. These transactions resulted in a $5.7 million increase in the Company’s investment in Radionetics. As a result of the August 2023 Radionetics Transaction, the Company experienced net dilution in its ownership of Radionetics from a 55% ownership stake in Radionetics common stock to a 31% combined ownership stake in Radionetics common and preferred stock. No gain was recorded upon dilution since cumulative losses that had been suspended exceeded the gain on dilution. Additionally, in December 2023, Radionetics completed a financing to sell additional shares of preferred stock to other investors.

The amendment to the Radionetics License in connection with the August 2023 Radionetics Transaction did not result in additional revenue at the time of modification and the sales-based milestone and royalty payments will only be recognized when the milestones or sales occur.

In June 2024, the Company amended the Radionetics License to reduce the number of development targets. Following the amendment to the Radionetics License, ownership of the non-licensed targets reverted back to the Company and the Company is eligible to receive total potential sales milestones in excess of $300.0 million and single-digit royalties on net sales. In July 2024, Radionetics announced the formation of a strategic partnership with Eli Lilly and Company, or Lilly. Under the terms of the agreement, Radionetics was entitled to receive a $140.0 million upfront cash payment and Lilly obtained the exclusive right to acquire Radionetics for $1.0 billion upon conclusion of an exercise period. During the exercise period, Radionetics will continue to build out a proprietary pipeline of therapeutic assets. As of December 31, 2024, the Company owned approximately 25% of Radionetics consisting of common and preferred stock.

During the year ended December 31, 2024, the Company recorded equity method losses of $0.5 million, in the accompanying consolidated statements of operations and comprehensive loss, as a result of the allocation of the Company’s share of Radionetics eligible losses, which is recorded on a quarterly lag. As of December 31, 2024 the Company's investment in Radionetics was written down to zero. As of December 31, 2023, the Company’s investment in Radionetics of $0.5 million is recorded as a long-term asset in the accompanying consolidated balance sheets.

Other Items

R. Scott Struthers, Ph.D., the Company’s President and Chief Executive Officer, serves as chairman of the Radionetics board of directors. Pursuant to such arrangement, Dr. Struthers receives consideration in the form of both equity and a $50,000 annual retainer for his service as a board member of Radionetics. As of December 31, 2024, Dr. Struthers has an approximately 1.3% ownership stake in Radionetics consisting of common stock.

As of December 31, 2024 and 2023, the Company had $0 and $0.1 million, respectively, due from Radionetics for reimbursement of certain expenses paid on behalf of Radionetics. These amounts are recorded within prepaid expenses and other current assets in the accompanying consolidated balance sheets. During the years ended December 31, 2024, 2023 and 2022, the Company received reimbursements from Radionetics of $0.1 million, $0.1 million, and $0.4 million, respectively.

The Company initially reserved 1,500,000 shares of the Company’s common stock for issuance pursuant to awards granted under the 2021 Inducement Plan. The terms of the 2021 Inducement Plan are substantially similar to the terms of the Company’s 2018 Incentive Award Plan with the exception that awards may only be made to an employee who has not previously been an employee or member of the board of directors of the Company if the award is in connection with commencement of employment. In 2022, the Company amended the 2021 Inducement Plan to increase the number of shares of the Company’s common stock available for future issuance under the 2021 Inducement Plan to 5,000,000 shares.

As of December 31, 2024,3,188,669 shares of common stock were available for future issuance under the 2021 Inducement Plan.

2018 Incentive Award Plan

The Company adopted the 2018 Incentive Award Plan (the “2018 Plan”) in July 2018. Under the 2018 Plan, which expires in July 2028, the Company may grant equity-based awards to individuals who are employees, officers, directors or consultants of the Company. Options issued under the 2018 Plan will generally expireten years from the date of grant and vest over afour-year period. As of December 31, 2024,3,037,080 shares of common stock were available for future issuance under the 2018 Plan.

The 2018 Plan contains a provision that allows annual increases in the number of shares available for issuance on the first day of each calendar year through January 1, 2028 in an amount equal to the lesser of: (i)5% of the aggregate number of shares of the Company’s common stock outstanding on December 31 of the immediately preceding calendar year, or (ii) such lesser amount determined by the Company. Under this evergreen provision, on January 1, 2025 an additional 4,646,320 shares became available for future issuance under the 2018 Plan.

2015 Stock Incentive Plan

Under this evergreen provision, on January 1, 2025, an additional 929,264 shares became available for future issuance under the ESPP.

Stock Awards

Stock Options

Activity under the Company’s stock option plans during the year ended December 31, 2024 was as follows:

Aggregate intrinsic value is calculated as the difference at a specific point in time between the closing price of the Company’s common stock at December 31, 2024 and the exercise price of stock options that had exercise prices below the closing price. The aggregate intrinsic value of options exercised during 2024, 2023 and 2022 was $72.1 million, $16.2 million and $5.9 million, respectively.

Restricted Stock Units

The Company’s restricted stock unit activity during the year ended December 31, 2024 was as follows:

The weighted average grant date fair value for restricted stock units granted during 2023 and 2022 was $19.62 and $19.90, respectively. The total fair value of restricted stock units that vested during 2024 and 2023 was $10.0 million and $1.4 million, respectively. No restricted stock units vested in 2022.

Fair Value of Stock Awards

The Company estimates the fair value of all stock option grants and the ESPP using the Black-Scholes option pricing model and recognizes forfeitures as they occur.

The following table summarizes the weighted average assumptions used to estimate the fair value of stock options granted under the Company’s stock option plans forthe periods presented below:

The weighted-average fair value of stock options awarded during the years ended December 31, 2024, 2023 and 2022 was$28.96, $13.09 and $14.50 per share, respectively.

The following table summarizes the weighted average assumptions used to estimate the fair value of the ESPP awards for the periods presented below:

The weighted-average fair value of awards under the ESPP during the years ended December 31, 2024, 2023 and 2022 was $22.09, $11.49 and $9.39 per share, respectively.

The key assumptions used in determining the fair value of equity awards, and the Company’s rationale, were as follows: (i)Expected term - the expected term for stock options represents the period that the stock options are expected to be outstanding and has been estimated using the simplified method, due to limited historical exercise behavior. The expected term using the simplified method is an average of the contractual option term and its vesting period; the expected term for awards granted under the ESPP represents the term the awards are expected to be outstanding; (ii) Expected volatility - Beginning in 2023, the Company determined that the volatility of its own market-traded shares best represents the expected volatility based on available historical data and, therefore, the expected volatility assumption for stock-based awards granted during the year ended December 31, 2024 is based on the historical volatility of the Company's common stock. During 2022, the expected volatility assumption was based on volatilities of a peer group of similar companies in the biotechnology industry whose share prices are publicly available. The Company computed the historical volatility data using the daily closing prices for the selected companies’ shares during the period equivalent to the expected term of the Company’s stock-based awards; (iii)Risk-free interest rate - the risk-free interest rate is based on the U.S. Treasury yield in effect at the time of grant for zero coupon U.S. Treasury notes with maturities that approximate the expected terms of awards; and (iv)Expected dividend yield - the expected dividend yield assumption iszero as the Company has never paid dividends and has no present intention to do so in the future.

Restricted stock units are valued using the closing sale price of our common stock on the date of grant.

Stock-Based Compensation Expense

Stock-based compensation expense for the equity awards issued by the Company to employees and non-employees for the periods presented below was as follows (in thousands):

As of December 31, 2024, unrecognized stock-based compensation cost related to option awards, restricted stock units, and ESPP was $142.3 million, $35.0 million and $3.9 million, respectively, which is expected to be recognized over a remaining weighted-average period of approximately 1.8 years,2.7 years and 1.4 years, respectively.

12. INCOME TAXES

The Company is subject to taxation in the United States, various state jurisdictions, Australia and Switzerland; however, as it has operated at a loss since inception, it has not paid income taxes in any of the jurisdictions in which it has operated. At December 31, 2024, the Company had federal, state, and foreign net operating loss ('NOL') carryforwards of approximately $431.2 million, $253.9 million and $3.1 million, respectively. The federal loss carryforwards generated after 2017 of $424.9 million will carryforward indefinitely and can be used to offset up to 80% of future annual taxable income, while those loss carryforwards generated prior to 2018 begin expiring in 2035, unless previously utilized. $2 million of the state loss carryforwards will carryforward indefinitely. The other state loss carryforwards begin expiring in 2035, unless previously utilized. The Company's foreign loss carryforwards do not expire. The Company also has federal and California R&D credit carryforwards and federal Orphan Drug Credits totaling $30 million, $14.9 million, and $26.3 million, respectively. The federal R&D credits begin to expire in 2030, unless previously utilized, while the state credits do not expire. The federal Orphan Drug credit carryforwards will begin to expire in 2040, unless previously utilized.

The Company’s NOL and credit carryforwards to offset future taxable income may be subject to a substantial annual limitation upon future utilization as a result of ownership changes that could occur in the future pursuant to Internal Revenue Code Sections 382 and 383. These ownership changes may limit the amount of NOL and credit carryforwards that can be utilized to offset future taxable income and tax, respectively. In general, an 'ownership change' as defined by the tax code results from a transaction or series of transactions over a three-year period resulting in an ownership change of more than 50 percent of the outstanding stock of a company by certain stockholders or public groups. During 2020, the Company completed a study to assess whether an ownership change within the meaning of Section 382 had occurred for the time period prior to July 15, 2020. The study identified several such ownership changes during the study period, which resulted in limitations on the annual utilization of the Company's NOL and credit carryforwards, or the "Tax Attribute" carryforwards; however, the study findings also indicated that none of the Company's Tax Attribute carryforwards generated during the study period would expire solely as a result of annual limitations on the utilization of such Tax Attribute carryforwards. The Company updated the study for 2022 and 2023 and did not identify any additional ownership changes. Future ownership changes could still occur which might place further limits on the Company's ability to utilize its Tax Attribute carryforwards.

The Company’s federal income tax returns from 2021 forward, state income tax returns from 2020 forward, and its Australian tax returns beginning in 2021 are subject to examination by tax authorities; however, the Company's tax attribute carryforwards such as NOLs and R&D credits generated in closed years remain subject to adjustment by the taxing authorities until the future tax years in which those attributes are utilized are closed to statute. No such audits are underway.

Deferred tax assets and liabilities

Net deferred tax assets are comprised of the following as of December 31, 2024 and 2023 (in thousands):

Realization of deferred tax assets is dependent upon future earnings, if any, the timing and amount of which are uncertain. Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use existing deferred tax assets. Based on the weight of available evidence, including the Company's history of operating losses, management has determined that it is more likely than not that the Company’s net deferred tax assets will not be realized. Accordingly, a valuation allowance has been established by the Company to fully offset these net deferred tax assets.

Changes to the Company’s unrecognized tax benefits are summarized in the following table (in thousands):

Due to the existence of the valuation allowance, future changes in unrecognized tax benefits would not have any effect on the Company’s effective tax rate. The Company does not foresee any material changes to its unrecognized tax benefits within the next twelve months. There have beenno decreases in unrecognized tax benefits due to settlements or expiration of statute of limitations for the assessment of taxes during the years ended December 31, 2024, 2023 and 2022.

The Company’s policy is to recognize the interest expense and/or penalties related to income tax matters as a component of income tax expense. The Company hadno accrual for interest or penalties on its consolidated balance sheets as of December 31, 2024 or December 31, 2023, and hasnot recognized interest and/or penalties in its consolidated statements of operations for the years ended December 31, 2024, December 31, 2023, and December 31, 2022 as the unrecognized tax benefits relate to tax positions for which no cash tax liability has been reduced.

In response to the pandemic, the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”) was signed into law on March 27, 2020. The CARES Act, among other things, includes tax provisions relating to refundable payroll tax credits, deferment of employer’s social security payments, net operating loss utilization and carryback periods, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property. The CARES Act did not have a material impact on our income tax provision for the year ended December 31, 2024, 2023, and 2022.

Deferred income taxes have not been provided for undistributed earnings of the Company’s consolidated foreign subsidiaries because the Parent entity would not be required to include the distribution into income as the amount would be tax free. The Company has no foreign withholding tax liability as of December 31, 2024 as a result of losses in foreign subsidiaries.

The Tax Cuts and Jobs Act subjects a US shareholder to tax on Global Intangible Low-Taxed Income ("GILTI") earned by certain foreign subsidiaries. The FASB Staff Q&A, Topic 740 No. 5. Accounting for Global Intangible Low-Taxed Income, states that an entity can make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future years or to provide for the tax expense related to GILTI in the year the tax is incurred as a period expense only. We have elected to account for GILTI in the year the tax is incurred.

13. SEGMENT REPORTING

Operating segments are identified as components of an enterprise for which separate discrete financial information is available for evaluation by the CODM in making decisions regarding the allocation of resources, assessing performance and monitoring budget versus actuals. The Company's CODM is its founder and chief executive officer. The Company views its operations and manages its business as one operating and reportable segment as the Company has devoted substantially all of its resources to drug discovery and development activities through conducting preclinical studies and clinical trials associated with its programs, all of which aim to discover, develop and commercialize novel therapeutics for rare endocrine diseases and endocrine-related tumors, as outlined in the table below. The Company's operating segment derives its revenues from licensing arrangements (see “Note 8”). The CODM assesses performance based on consolidated net loss as reported on the consolidated statement of operations and comprehensive loss. The measure of segment assets is reported on the consolidated balance sheet as total consolidated assets. Further, segment depreciation expense and segment asset additions are consistent with consolidated amounts reported within the consolidated statement of cash flows given the Company's operations are aggregated within a single reportable segment. Substantially all of the Company’s assets and sources of revenues are located in the United States. The total segment amount of equity method investments for the segment is also consistent with the consolidated amount of equity method investments reported within the consolidated balance sheet.

Segment revenue and significant segment expenses which are regularly reported to the CODM are included within the table below and are reconciled to consolidated net loss:
