Report of Independent Registered Public Accounting Firm
To the Stockholders and the Board of Directors of Cyclerion Therapeutics, Inc.
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Cyclerion Therapeutics, 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 two 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 two years in the period ended December 31, 2024, in conformity with U.S. generally accepted accounting principles.
The Company's Ability to Continue as a Going Concern
The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has suffered recurring losses from operations, has limited financial resources, and has stated that substantial doubt exists about the Company’s ability to continue as a going concern. Management's evaluation of the events and conditions and management’s plans regarding these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.
Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (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 financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the 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 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 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 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 financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the 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.

Assessment of indicators of impairment of investment in Tisento Therapeutics Holdings Inc. |
Description of the Matter |
|
As discussed in Notes 2 and 5 to the consolidated financial statements, as of December 31, 2024, the Company had recognized an Other investment of $5.4 million which was accounted for as a financial instrument without a readily determinable fair value. Such investment was recorded using the measurement alternative for investments without readily determinable fair values, whereby the investment was measured at cost less any impairment recorded or adjustments for observable price changes. As of December 31, 2024, no impairment loss was recognized. Auditing the Company's assessment of indicators of impairment of the Other investment was complex and required significant judgment in applying our audit procedures and in the evaluation of the results of the procedures performed to determine if any impairment indicators were present. In addition, there was a significant degree of subjectivity in evaluating the relevance and reliability of the audit evidence obtained. |
How We Addressed the Matter in Our Audit |
|
We performed audit procedures to test management’s evaluation of events or changes in circumstances that might be indicators of impairment of the Company’s Other investment. Such procedures included, among others: (i) evaluating the appropriateness of management’s assessment of indicators of impairment; (ii) independently obtaining and assessing evidence, including from external sources, to corroborate management’s judgments and evaluating contrary evidence; (iii) reading the minutes of the Company’s Board of Directors meetings; and (iv) performing inquiries of management of Tisento Therapeutics Holdings Inc. and the Company regarding their knowledge of impairment indicators. |
We have served as the Company’s auditor since 2018.

Cyclerion Therapeutics, Inc.
Notes to the Consolidated Financial Statements
1. Nature of Business
Nature of Operations
Cyclerion Therapeutics, Inc. (“Cyclerion”, the “Company” or “we”) became an independent public company on April 1, 2019 after Ironwood Pharmaceuticals, Inc. completed a tax-free spin-off of their sGC business. Cyclerion is focused on building a new pipeline with therapeutics to treat certain neuropsychiatric diseases. Cyclerion has prioritized an individualized therapy for treatment resistant depression (“TRD”) as its foundational product candidate and has entered into a non-binding option to license agreement for the intellectual property associated with this product. With the large unmet medical need in TRD, the clinical development stage of this asset, and the strong commercial opportunity, the Company believes that this product is well suited to be its foundation moving forward for Cyclerion. The Company is currently developing an integrated development and commercial strategy in TRD. Cyclerion has one employee as of December 31, 2024.
At inception, Cyclerion was a biopharmaceutical company focused on the treatment of serious diseases with novel soluble guanylate cyclase (“sGC”) stimulators in both the central nervous system (“CNS”) and the periphery. The Company’s strategy changed and Cyclerion's sGC assets have either been sold, out-licensed or has plans to be out-licensed to a third party. The Company’s prior strategy to conduct research and development on sGC stimulators has been discontinued and Cyclerion does not intend to internally pursue research and development or commercialization with any sGC asset. The Company is leveraging its legacy sGC stimulator assets to generate revenues which, in the near-term will be used to implement its strategic building plan in TRD.
Praliciguat is an orally administered, once-daily systemic sGC stimulator. On June 3, 2021, Cyclerion entered into a license agreement with Akebia Therapeutics Inc. (“Akebia”) relating to the exclusive worldwide license to Akebia of our rights to the development, manufacture, medical affairs and commercialization of pharmaceutical products containing praliciguat and other related products and forms thereof enumerated in such agreement.
On December 13, 2024, Cyclerion announced that Cyclerion and Akebia have re-negotiated a mutually beneficial amendment to their exclusive license agreement for praliciguat, a systemic sGC stimulator. Under this new license amendment, Cyclerion will receive $
Olinciguat is a Phase 2, orally administered, once-daily, vascular sGC stimulator. On July 22, 2024, the Company entered into an Option to License Agreement (the “Option Agreement”) with a third party (the “Optionee”), pursuant to which the Optionee has an option (the “Option”) to enter into an exclusive license to olinciguat for human therapeutics, subject to certain carveouts. Under the terms of the Option Agreement, the Optionee paid the Company an Option fee of $
Zagociguat is a clinical-stage CNS-penetrant sGC stimulator that has shown rapid improvement in cerebral blood flow, functional brain connectivity, brain response to visual stimulus, cognitive performance, and biomarkers

associated mitochondrial function and inflammation in clinical studies. CY3018 is a CNS-targeted sGC stimulator that preferentially localizes to the brain and has a pharmacology profile that suggests its potential for the treatment of neuropsychiatric diseases and disorders. On July 28, 2023, the Company sold Zagociguat and CY3018 to Tisento Therapeutics, Inc. (“Tisento”), a newly formed private company focused on their development, in exchange for $
Cyclerion GmbH, a wholly owned subsidiary, was incorporated in Zug, Switzerland on May 3, 2019. The functional currency is the Swiss franc. Cyclerion GmbH was liquidated and de-registered in May 2024.
Cyclerion Securities Corporation, a wholly owned subsidiary, was incorporated in Massachusetts on November 15, 2019 and was granted securities corporation status in Massachusetts.
Stock Purchase Agreement
In March 2023, the Company entered into a stock purchase agreement with the Company's former Chief Executive Officer (the “CEO”) pursuant to which he invested $
Asset Purchase Agreement
On May 11, 2023, the Company entered into an Asset Purchase Agreement (the “Asset Purchase Agreement”) with an investor group that included the former CEO, JW Celtics Investment Corp and JW Cycle Inc. which subsequently changed their names to Tisento Therapeutics Holdings Inc. (“Tisento Parent”) and Tisento. Upon the closing on July 28, 2023, of the transactions contemplated by the Asset Purchase Agreement, the Company sold to Tisento specified assets relating to the Company’s zagociguat and CY3018 programs (the "Transferred Assets") and Tisento assumed certain liabilities relating thereto, including, but not limited to (i) liabilities, costs and expenses arising after the date of the Asset Purchase Agreement relating to the employment of certain Cyclerion employees and the conduct of certain preclinical and clinical trial activities prior to the closing of the transactions contemplated by the Asset Purchase Agreement, and (ii) liabilities relating to such assets to the extent relating to the period after the closing of the transaction. In consideration for such sale and assumption, at such closing the Company received proceeds of $8.0 million as cash consideration, $2.4 million as reimbursement for certain operating expenses related to such assets for the period between signing and closing of the Asset Purchase Agreement, and shares of common stock of Tisento Parent comprising 10% of the then issued and outstanding equity securities of Tisento Parent immediately following such closing, subject to certain protections against dilution.
Reverse Stock Split
On May 15, 2023, the Company filed Articles of Amendment to the Company's Restated Articles of Organization with the Secretary of Commonwealth of Massachusetts to effect a 1-for-20 reverse stock split of the Company's issued and outstanding shares of common stock. The reverse stock split was reflected on the Nasdaq Capital Market beginning with the opening of trading on May 16, 2023. All share amounts and per share amounts disclosed in this Annual Report on Form 10-K have been adjusted retroactively to reflect the reverse stock split for all periods presented.
At-the-Market Offering
On September 3, 2020, the Company entered into a Sales Agreement (the “Sales Agreement”) with Jefferies LLC (“Jefferies”) with respect to an at-the-market offering (the “ATM Offering”) under the 2020 Shelf. Under the ATM Offering, the Company could offer and sell, from time to time at its sole discretion, shares of its common stock, having an aggregate offering price of up to $

Basis of Presentation
The consolidated financial statements and the related disclosures have been prepared in accordance with U.S. generally accepted accounting principles. In the opinion of management, the consolidated financial statements reflect all normal recurring adjustments considered necessary for a fair presentation of the Company’s financial position and the results of its operations for the fiscal years presented.
The consolidated financial statements include the financial statements of the Company and its wholly owned subsidiaries, Cyclerion Securities Corporation and Cyclerion GmbH which was dissolved in May 2024. All significant intercompany accounts and transactions have been eliminated in the preparation of the accompanying consolidated financial statements.
Going Concern
At each reporting period, in accordance with Accounting Standards Codification ("ASC") 205-40, Going Concern, the Company evaluates whether there are conditions or events that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued. The Company’s evaluation entails analyzing prospective operating budgets and forecasts for expectations of the Company’s cash needs and comparing those needs to the current cash and cash equivalent balances. The Company is required to make certain additional disclosures if it concludes substantial doubt exists and it is not alleviated by the Company’s plans or when its plans alleviate substantial doubt about the Company’s ability to continue as a going concern.
This evaluation initially does not take into consideration the potential mitigating effect of management’s plans that have not been fully implemented as of the date the financial statements are issued. When substantial doubt exists under this methodology, management evaluates whether the mitigating effect of its plans sufficiently alleviates substantial doubt about the Company’s ability to continue as a going concern. The mitigating effect of management’s plans, however, is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that the financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that these consolidated financial statements are issued. In performing its analysis, management excluded certain elements of its operating plan that cannot be considered probable. Under ASC 205-40, the future receipt of potential funding from future partnerships, equity or debt issuances, certain cost reduction measures and the potential milestones from the Akebia agreement cannot be considered probable at this time because these plans are not entirely within the Company’s control and/or have not been approved by the Board of Directors as of the date of these consolidated financial statements.
The Company expects that its cash and cash equivalents as of December 31, 2024, will be sufficient to fund operations through mid-2025, however the Company will need to obtain additional funding to sustain operations as it expects to continue to generate operating losses for the foreseeable future. The Company's expectation to generate negative operating cash flows in the future and the need for additional funding to support its planned operations, raise substantial doubt regarding the Company’s ability to continue as a going concern. Management's plans to alleviate the conditions that raise substantial doubt include reduced spending, and the pursuit of additional capital. Management has concluded the likelihood that its plan to successfully obtain sufficient funding, or adequately reduce expenditures, while reasonably possible, is less than probable. Accordingly, the Company has concluded that substantial doubt exists about the Company’s ability to continue as a going concern. The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of the uncertainties described above.

2. Summary of Significant Accounting Policies
Segment Information
The Company operates and manages its business as a single segment for the purposes of assessing performance and making operating decisions. The Company’s president and chief executive officer, who is the chief operating decision maker ("CODM"), reviews the Company’s financial information on a consolidated basis for purposes of evaluating financial performance and allocating resources. When evaluating the Company’s financial performance, the CODM regularly reviews net loss, non-operating expenses and operating expenses excluding non-cash stock based compensation expense.
Discontinued Operations
In accordance with ASC 205-20 “Presentation of Financial Statements: Discontinued Operations”, a disposal of a component of an entity or a group of components of an entity is required to be reported as discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. In the period in which the component meets held-for-sale or discontinued operations criteria the major current assets, non-current assets, current liabilities, and non-current liabilities shall be reported as components of total assets and liabilities separate from those balances of the continuing operations and disclosed in the notes to financial statements. At the same time, the results of all discontinued operations, less applicable income taxes, shall be reported as components of net loss separate from the net income (loss) of continuing operations.
The Transferred Assets met the definition of a discontinued operation. Accordingly, the Company has classified the results of the Transferred Assets as discontinued operations in its consolidated statements of operations for all periods presented. All assets and liabilities associated with the Transferred Assets were classified as assets and liabilities of discontinued operations in the Note 4, "Discontinued Operations". All amounts included in the notes to the consolidated financial statements relate to continuing operations unless otherwise noted. For additional information, see Note 4, “Discontinued Operations”.
Variable Interest Entities
The Company reviews each legal entity in which it has a financial interest to determine whether or not the entity is a variable interest entity or VIE. If the entity is a VIE, the Company assesses whether or not it is the primary beneficiary of that VIE based on a number of factors, including (i) which party has the power to direct the activities that most significantly affect the VIE’s economic performance, (ii) the parties’ contractual rights and responsibilities pursuant to any contractual agreements and (iii) which party has the obligation to absorb losses or the right to receive benefits from the VIE. If the Company determines that it is the primary beneficiary of a VIE, it consolidates the financial statements of the VIE into its consolidated financial statements at the time that determination is made. On a quarterly basis, the Company evaluates whether it continues to be the primary beneficiary of any consolidated VIEs. If the Company determines that it is no longer the primary beneficiary of a consolidated VIE, or no longer has a variable interest in the VIE, the Company deconsolidates the VIE in the period that the determination is made.
Investment
The Company accounts for investments in equity securities without a readily determinable fair value at cost, minus impairment. If the Company identifies observable price changes in orderly transactions for an identical or a similar investment of the same issuer, the Company will measure the equity security at fair value as of the date that the observable transaction occurred in accordance with ASC Topic 321, Investments-Equity Securities.
Use of Estimates
The preparation of consolidated financial statements in accordance with U.S. generally accepted accounting principles ("GAAP") requires the Company’s management to make estimates and judgments that may affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the
F-11
consolidated financial statements, and the amounts of expenses during the reported periods. On an ongoing basis, the Company’s management evaluates its estimates, judgments and methodologies. Significant estimates and assumptions in the consolidated financial statements include those related to revenue, fair value determination of other investment, impairment of long-lived assets, valuation procedures for right-of-use ("ROU") assets and operating lease liabilities, income taxes, including the valuation allowance for deferred tax assets, research and development expenses, contingencies, share-based compensation and going concern. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ materially from these estimates under different assumptions or conditions. Changes in estimates are reflected in reported results in the period in which they become known.
Cash and Cash Equivalents
Property and Equipment
Property and equipment are recorded at cost, and are depreciated when placed into service using the straight-line method based on their estimated useful lives as follows:
Asset Description |
|
Estimated Useful |
Computer equipment |
|
|
Software |
|
Software costs incurred during the preliminary project stage are expensed as incurred, while costs incurred during the application development stage are capitalized and amortized over the estimated useful life of the software. The Company also capitalizes costs related to specific upgrades and enhancements when it is probable the expenditures will result in additional functionality. Maintenance and training costs related to software obtained for internal use are expensed as incurred.
Costs for capital assets not yet placed into service have been capitalized as construction in progress and are depreciated in accordance with the above guidelines once placed into service. Maintenance and repair costs are expensed as incurred.
Fair Value of Investment Instruments
Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable:
F-12
Foreign Currency Translation Adjustment
The functional currency of the Company’s former foreign subsidiary is its local currency, the Swiss franc. The assets and liabilities of the Company’s former foreign subsidiary are translated into U.S. dollars at exchange rates in effect at the balance sheet date. Income and expense items are translated at the average exchange rates prevailing during the period. The cumulative translation effect for the Company’s former foreign subsidiary was included as a foreign currency translation adjustment in the consolidated statements of stockholders’ equity and as a component of comprehensive loss in the consolidated statements of operations and comprehensive loss.
The Company’s intercompany accounts are typically denominated in the functional currency of the foreign subsidiary. Gains and losses resulting from the re-measurement of intercompany balances are recorded in the consolidated statements of operations.
Accounts Receivable
The Company makes judgments as to its ability to collect outstanding receivables and provides an allowance for receivables when collection becomes doubtful. Provisions are made based upon a specific review of all significant outstanding invoices. The Company believes that credit risks associated with these agreements are not significant. To date, the Company has not had significant write-offs of bad debt and the Company did not have an allowance for doubtful accounts as of December 31, 2024 or 2023.
Impairment of Long-Lived Assets
The Company regularly reviews the carrying amount of its long-lived assets to determine whether indicators of impairment may exist, which warrant adjustments to carrying values or estimated useful lives. If indications of impairment exist, projected future undiscounted cash flows associated with the asset are compared to the carrying amount to determine whether the asset’s value is recoverable. If the carrying value of the asset exceeds such projected undiscounted cash flows, the asset will be written down to its estimated fair value. There were no significant impairments of long-lived assets for the years ended December 31, 2024 or 2023, except for the impairment loss of right-of-use assets recognized during the year ended December 31, 2023.
Leases
The Company had a property lease for its headquarters location at 301 Binney Street, Cambridge, MA (the “Head Lease”). The Company determined if the arrangement was a lease at the inception of the contract. The asset component of the Company’s operating leases was recorded as operating lease right-of-use assets, and the liability component was recorded as current portion of operating lease liabilities and operating lease liabilities, net of current portion, in the Company’s consolidated balance sheets.
Right-of-use assets (ROU) assets and operating lease liabilities are recognized based on the present value of lease payments over the lease term at the commencement date. The Company uses an incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments if an implicit rate of return is not provided with the lease contract. Operating lease ROU assets are adjusted for incentives received.
Lease cost was recognized on a straight-line basis over the lease term, and included amounts related to short-term leases. Variable lease costs that do not depend on an index or rate were recognized as incurred.
F-13
ROU assets and operating lease liabilities were remeasured upon certain modifications to leases using the present value of remaining lease payments and estimated incremental borrowing rate upon lease modification. The difference between the remeasured ROU assets and the operating lease liabilities were recognized as a gain or loss in operating expenses. The Company reviewed any changes to its lease agreements for potential modifications and/or indicators of impairment of the respective ROU asset. During the year ended December 31, 2023, the Company recorded $
Revenue
Upon executing a revenue generating arrangement, the Company assesses whether it is probable the Company will collect consideration in exchange for the good or service it transfers to the customer. To determine revenue recognition for arrangements that the Company determines are within the scope of ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”), it performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the Company satisfies the performance obligations. The Company must develop assumptions that require significant judgment to determine the stand-alone selling price for each performance obligation identified in the contract. The assumptions that are used to determine the stand-alone selling price may include forecasted revenues, development timelines, reimbursement rates for personnel costs, discount rates and probabilities of technical and regulatory success. The Company derives revenue from (1) license agreement and (2) option to license agreement which are fully described in Note 15, License Agreement.
Research and Development Costs
The Company expenses research and development costs to operations as incurred. The Company defers and capitalizes nonrefundable advance payments made by the Company for research and development activities until the related goods are received or the related services are performed. The Company estimates the period over which such services will be performed and the level of effort to be expended in each period. If actual timing of performance or the level of effort varies from the estimate, the Company will adjust the amounts recorded accordingly. The Company has not experienced any material differences between accrued or prepaid costs and actual costs since inception.
Research and development expenses are comprised of costs incurred in performing research and development activities, which may include salary, benefits and other employee-related expenses; share-based compensation expense; laboratory supplies and other direct expenses; facilities expenses; overhead expenses; third-party contractual costs relating to nonclinical studies and clinical trial activities and related contract manufacturing expenses, development of manufacturing processes and regulatory registration of third-party manufacturing facilities; and other outside expenses.
General and Administrative Expenses
The Company expenses general and administrative costs to operations as incurred. General and administrative expense consists of compensation, share-based compensation, benefits and other employee-related expenses for personnel and outside consultants providing the Company’s administrative, finance, legal, information technology, business development and human resource functions. Other costs include the legal costs of pursuing patent protection of the Company’s intellectual property, general and administrative related facility costs, insurance costs and professional fees for accounting and legal services.
Income taxes
The Company is primarily subject to U.S. Federal and Massachusetts state income taxes. For federal and state income taxes, deferred tax assets and liabilities are recognized based upon temporary differences between the financial statement and the tax basis of assets and liabilities. Deferred income taxes are based upon prescribed rates and enacted laws applicable to periods in which differences are expected to reverse. A valuation allowance is recorded when it is more likely than not that some portion or all of the deferred tax assets will not be
F-14
realized. Accordingly, the Company provides a valuation allowance, if necessary, to reduce deferred tax assets to amounts that are realizable.
The tax positions taken or expected to be taken in the course of preparing the Company tax returns are required to be evaluated to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Tax positions not deemed to meet a more-likely-than-not threshold would be recorded as a tax expense in the current year. The determination as to whether the tax benefit will more likely than not be realized is based upon the technical merits of the tax position as well as consideration of the available facts and circumstances. It does not consider the likelihood of whether or not the IRS will review the position. Cyclerion evaluates uncertain tax positions on a quarterly basis and adjusts the level of the liability to reflect any subsequent changes in the relevant facts surrounding the uncertain positions. Any changes to these estimates, based on the actual results obtained and/or a change in assumptions, could affect Cyclerion's income tax provision in future periods. There were no uncertain tax positions that require accrual or disclosure in the consolidated financial statements as of December 31, 2024, and 2023. The Company’s policy is to recognize interest and penalties related to income tax, if any, in income tax expense. As of December 31, 2024 and 2023, the Company has

Subsequent Events
The Company considers events or transactions that have occurred after the balance sheet date of December 31, 2024, but prior to the filing of the financial statements with the Securities and Exchange Commission, to provide additional evidence relative to certain estimates or to identify matters that require additional recognition or disclosure. Subsequent events have been evaluated through the filing of the financial statements accompanying this Annual Report on Form 10-K. See Note 16, Subsequent Events.
Recently Issued Accounting Pronouncements
From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) or other standard setting bodies that are adopted by the Company as of the specified effective date. Except as discussed elsewhere in the notes to the consolidated financial statements, the Company did not adopt any new accounting pronouncements during the years ended December 31, 2024 and 2023, that had a material effect on its consolidated financial statements.
Recently Adopted Accounting Pronouncements
In June 2016 the FASB issued ASU 2016-13, Financial Instruments-Credit Losses. This standard requires entities to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. As a smaller reporting company, ASU 2016-13 became effective for the Company for fiscal years beginning after December 15, 2022. The Company adopted ASU 2016-13 in the first quarter of 2023, and the adoption of this standard did not have any impact on the Company's financial position or results of operations.
F-15
In November 2023 the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which expands annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses. The Company adopted this standard effective January 1, 2024 using a retrospective method, and the adoption of this standard did not have any impact on the Company's financial position or results of operations. For further information, refer to the Segments section in Note 2 “Summary of Significant Accounting Policies.”
No other accounting standards known by the Company to be applicable to it that have been issued by the FASB or other standard-setting bodies and that do not require adoption until a future date are expected to have a material impact on the Company’s consolidated financial statements upon adoption.
3. Fair Value of Financial Instruments
The Company’s cash equivalents are generally classified within Level 1 of the fair value hierarchy. The following tables present information about the Company’s financial assets measured at fair value on a recurring basis and indicate the level of the fair value hierarchy used to determine such fair values as of December 31, 2024 and December 31, 2023 (in thousands):

During the year ended December 31, 2024 and 2023, there were no transfers between levels. The fair value of the Company's cash equivalents, consisting of money market funds, is based on quoted market prices in active markets with no valuation adjustment.
The Company believes the carrying amounts of its accounts receivable, prepaid expenses and other current assets, accounts payable, and accrued expenses approximate their fair value due to the short-term nature of these amounts.
4. Discontinued Operations
On May 11, 2023, the Company entered into the Purchase Agreement with Tisento for Tisento’s acquisition of substantially all of the assets comprising the Company’s zagociguat and CY3018 programs, in exchange for consideration at closing of $
The carrying value of the disposal group was lower than its fair value, less costs to sell, and accordingly, a gain on disposal was recorded during the year ended December 31, 2023. The operations of the Transferred Assets are presented as discontinued for all periods presented. The transaction closed on July 28, 2023.

5. Other Investment
On July 28, 2023, the Company closed the transactions contemplated by the Asset Purchase Agreement receiving proceeds of $
The Company has determined that the Company’s investment in Tisento Parent is an equity security, whereby such investment does not give the Company a controlling financial interest or significant influence over the investee. Further, the Company assessed the accounting for its investment in Tisento Parent in accordance
F-17
with ASC 810-10, Consolidation—Overall. After determining that no scope exception applies under the guidance of ASC 810-10-15-12 and ASC 810-10-15-17, the Company concluded that it has a variable interest in Tisento Parent through its investment in Tisento Parent common stock. Tisento Parent does not have sufficient equity to finance its activities without additional subordinated financial support as Tisento Parent is a startup entity in its early stages of raising funds and will require significant capital to advance its programs to commercial stage. Therefore, the Company concluded that its investment in Tisento Parent is a variable interest entity (“VIE”) in accordance with ASC 810-10-15-14(a) and is subject to potential consolidation under the VIE model. However, all activities that most significantly impact Tisento Parent and its subsidiary’s economic performance are directed by the Tisento Parent board and the board approves decisions by a simple majority. Based on the board composition, the Company determined that no one party has control over the Tisento Parent board and power is not shared because the activities that most significantly affect Tisento Parent and its subsidiary’s economic performance do not require the consent of all of the parties. Rather, all decisions are made by a simple majority vote of the Tisento Parent board. Therefore, because the Company controls no director of Tisento Parent, the Company cannot unilaterally direct any of the activities that most significantly impact Tisento Parent and its subsidiary’s economic performance. Accordingly, the Company does not hold a controlling financial interest in Tisento Parent. Because both criteria (a) and (b) above have to be met for the application of the guidance in ASC 810-10-25-44B and criteria (a) has not been met, The Company concluded that it should not consolidate Tisento under the VIE model.
Accordingly, the Company has accounted for the investment as a financial instrument without a readily determinable fair value. Such investment is recorded using the measurement alternative for investments without readily determinable fair values, whereby the investment is measured at cost less any impairment recorded or adjustments for observable price changes. An impairment loss is recognized in the consolidated statements of operations and comprehensive loss equal to the amount by which the carrying value exceeds the fair value of the investment. As of December 31, 2024,
The initial fair value of the investment in Tisento Parent was determined by reference to the risk-adjusted net assets value using the discounted cash flow method. The estimated net assets value of Tisento Parent includes the cash generated/used from the operations and the proceeds from equity financing. Valuations were derived by reference to observable valuation measures for comparable companies or transactions, including weighted average cost of capital (

8. Commitments and Contingencies
Other Funding Commitments
In the normal course of business, the Company enters into contracts with clinical research organizations and other third parties for clinical and preclinical research studies and other services and products for operating purposes. These contracts are generally cancellable, with notice, at the Company’s option and do not have any significant cancellation penalties.
Guarantees
On September 6, 2018, Cyclerion was incorporated in Massachusetts and its officers and directors are indemnified for certain events or occurrences while they are serving in such capacity.
The Company enters into certain agreements with other parties in the ordinary course of business that contain indemnification provisions. These typically include agreements with directors and officers, business partners, contractors, clinical sites and customers. Under these provisions, the Company generally indemnifies and holds harmless the indemnified party for losses suffered or incurred by the indemnified party as a result of the Company’s activities. These indemnification provisions generally survive termination of the underlying agreements. The maximum potential amount of future payments the Company could be required to make under these indemnification provisions is unlimited. However, to date the Company has not incurred material costs to defend lawsuits or settle claims related to these indemnification provisions. As a result, the estimated fair value of these obligations is minimal. Accordingly, the Company did

9. Leases
On September 15, 2020, the Company entered into a Sublease Termination Agreement (the "Sublease Termination Agreement") to terminate its sublease of
The Company determined that the Sublease Termination Agreement constituted a non-monetary exchange under ASC 845 Nonmonetary Transactions (“ASC 845”) where, in return for the free rooms and the services, the Company agreed to terminate its rights and obligations under the sublease agreement. In accordance with ASC 845, the Company determined that the accounting for the transaction should be based on the fair value of assets or services involved. During the year ended December 31, 2020, the Company estimated the fair value of the rooms and services to be approximately $
F-19
The Company determined that the licensed rooms represent a lease under ASC Topic 842 Leases. The Company obtained control of the rooms in the third quarter of 2021 and the prepaid rooms balance of approximately $
After the closing of the Asset Purchase Agreement, the Company had no plans in the foreseeable future to use the licensed rooms and the Company is restricted from subleasing the rooms. In August 2023, the ROU asset and other assets were fully impaired, and the Company recognized a $
10. Share-based Compensation Plans
In 2019, Cyclerion adopted share-based compensation plans. Specifically, Cyclerion adopted the 2019 Employee Stock Purchase Plan (“2019 ESPP”) and the 2019 Equity Incentive Plan (“2019 Equity Plan”). Under the 2019 ESPP, eligible employees may use payroll deductions to purchase shares of stock in offerings under the plan, and thereby acquire an interest in the future of the Company. The 2019 Equity Plan provides for stock options, restricted stock awards ("RSAs") and restricted stock units (“RSUs”).
Cyclerion also mirrored two of Ironwood Pharmaceuticals, Inc. ("Ironwood") existing plans, the Amended and Restated 2005 Stock Incentive Plan (“2005 Equity Plan”) and the Amended and Restated 2010 Employee, Director and Consultant Equity Incentive Plan (“2010 Equity Plan"). These mirror plans were adopted to facilitate the exchange of Ironwood equity awards for Cyclerion equity awards upon the Separation as part of the equity conversion. As a result of the Separation and in accordance with the EMA, employees of both companies retained their existing Ironwood vested options and received a pro-rata share of Cyclerion options, regardless of which company employed them post-Separation. For employees that were ultimately employed by Cyclerion, unvested Ironwood options and RSUs were converted to unvested Cyclerion options and RSUs.
The following table provides share-based compensation reflected in the Company’s consolidated statements of operations and comprehensive loss for the years ended December 31, 2024 and 2023 (in thousands):

Stock Options
Stock options granted under the Company’s equity plans generally have a ten-year term and vest over a period of four years, provided the individual continues to serve at the Company through the vesting dates. Options granted under all equity plans are exercisable at a price per share not less than the fair market value of the underlying common stock on the date of grant. The estimated fair value of options, including the effect of estimated forfeitures, is recognized over the requisite service period, which is typically the vesting period of each option.

The effective income tax rate is based upon the income for the year, the composition of the income in different countries, and adjustments, if any, for the potential tax consequences, benefits or resolutions of audits or other tax contingencies. The Company's income tax rate in foreign jurisdictions is lower than the Company's income tax rate in the United States.

The Company has evaluated the positive and negative evidence bearing upon the possible realization of its deferred tax assets. Management has considered the Company's history of operating losses, in addition to the expected timing of the reversal of existing temporary differences and concluded, in accordance with the applicable accounting standards, that it is more likely than not that the Company will not realize the benefit of its deferred tax assets. Accordingly, the net deferred tax assets have been fully reserved at December 31, 2024 and December 31, 2023. Management reevaluates the positive and negative evidence on a quarterly basis.
The valuation allowance increased by approximately $
The Company did not generate net operating loss carryforwards or tax credit carryforwards available for its use until its inception and operation as a standalone legal entity. At December 31, 2024 and 2023, Cyclerion has federal net operating loss carryforwards of approximately $
F-24
and 2023, to offset future federal and state income taxes.
The Company’s ability to use its operating loss carryforwards and tax credits to offset future taxable income could be subject to restrictions under Section 382 of the U.S. Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). These potential restrictions may limit the future use of the operating loss carryforwards and tax credits if certain ownership changes described in the Internal Revenue Code occur. Changes in stock ownership may occur that would create these limitations on the Company’s use of the operating loss carryforwards and tax credits. In such a situation, the Company may be required to pay income taxes, even though significant operating loss carryforwards and tax credits exist.
The Company has not as yet conducted a study of its research and development credit carry forwards. This study may result in an adjustment to the Company’s research and development credit carryforwards; however, until a study is completed and any adjustment is known, no amounts are being presented as an uncertain tax position. A full valuation allowance has been provided against the Company’s research and development credits, and if an adjustment is required, this adjustment would be offset by an adjustment to the valuation allowance. Thus, there would be no impact to the consolidated balance sheets or statements of operations if an adjustment were required.
Upon audit, taxing authorities may challenge all or part of an uncertain income tax position. While Cyclerion has no history of tax audits since its inception on a standalone basis, it may be subject to tax audits by federal and state taxing authorities in the future. Accordingly, Cyclerion regularly assesses the outcome of potential examinations in each of the taxing jurisdictions when determining the adequacy of the amount of unrecognized tax benefit recorded.

Pursuant to the Akebia License Agreement, Akebia will be responsible for all future research, development, regulatory, and commercialization activities for the Products.
Akebia paid a $
Under the terms of the Amendment, Akebia paid the Company $
Pursuant to the Akebia License Agreement, the Company determined the Akebia License Agreement represents a service arrangement under the scope of ASC 606. Given the reversion of the rights under the Akebia License Agreement represents a penalty in substance for a termination by Akebia, the contract term would be the stated term of the License Agreement.
The Company determined that the grant of license to its patents and trademarks, know how transfer, the assignment of regulatory submissions and trademarks and additional knowledge transfer assistance obligations represent a single promise and performance obligation to be transferred to Akebia over time due to the nature of the promises in the contract. The provision of development materials on hand was identified as a separate performance

obligation. However, it is immaterial in the context of the contract as the development materials are low value and do not have an alternative use to the Company.
The consideration related to sales-based milestone payments, including royalties, will be recognized when the related sales occur as these amounts have been determined to relate predominantly to the license. The Company will re-evaluate the probability of achievement of the milestones and any related constraints each reporting period.
16. Subsequent Events
The Company has evaluated all events and transactions that occurred after the balance sheet date through the date the consolidated financial statements were issued.
On February 4, 2025, the Company filed a Registration Statement on Form S-3 with the SEC in relation to the registration of common stock, preferred stock, warrants and units of any combination thereof for an aggregate initial offering price not to exceed $
