Larimar Therapeutics, Inc.

Description of Business and Basis of Presentation

Larimar Therapeutics, Inc., together with its subsidiary (the “Company” or “Larimar”), is a clinical-stage biotechnology company focused on developing treatments for patients suffering from complex rare diseases using its novel cell penetrating peptide technology platform. Larimar's lead product candidate, nomlabofusp (nomlabofusp is the International Nonproprietary Name and the United States Adopted Name for CTI-1601), is a subcutaneously administered, recombinant fusion protein intended to deliver human frataxin ("FXN"), an essential protein, to the mitochondria of patients with Friedreich’s ataxia ("FA"). FA is a rare, progressive and fatal disease in which patients are unable to produce sufficient FXN due to a genetic abnormality.

Larimar has completed two Phase 1 clinical trials and a Phase 2 dose exploration trial, and has an ongoing Phase 2 OLE trial in patients with FA and an ongoing run-in study in adolescent patients with FA.

In May 2021, the Company reported positive top-line data from its Phase 1 FA program after completing dosing of the single ascending dose ("SAD") trial in December 2020 and of the multiple ascending dose ("MAD") trial in March 2021. Data from these trials demonstrated proof-of-concept by showing that daily subcutaneous injections of nomlabofusp for up to 13 days resulted in dose-dependent increases in FXN levels from baseline compared to placebo in all evaluated tissues (buccal cells, skin, and platelets). There were no serious adverse events associated with either the MAD or SAD trials.

In May 2023, the Company reported preliminary unblinded top-line data from the 25 mg cohort of the Phase 2 four-week, placebo-controlled, dose exploration trial of nomlabofusp in FA patients. Data from the cohort indicated nomlabofusp was generally well tolerated and showed increases in FXN levels from baseline compared to placebo in all evaluated tissues (skin and buccal cells) at day 14.

In July 2023, the FDA cleared initiation of a second cohort (50 mg) of the four-week, placebo-controlled, Phase 2 dose exploration trial of nomlabofusp in patients with FA and the initiation of the OLE trial with daily dosing of 25 mg.

In February 2024, the Company reported positive top-line data and successful completion of the Phase 2 dose exploration study. Nomlabofusp was generally well tolerated throughout the four-week treatment periods, had a predictable pharmacokinetic profile and led to dose dependent increases in FXN levels in all evaluated tissues (skin and buccal cells) after daily dosing of 14 days followed by every other day dosing until day 28 in the 25 mg and 50 mg cohorts. Participants in the 25 mg (n=13) and 50 mg (n=15) cohorts were randomized 2:1 to receive subcutaneous injections of nomlabofusp or placebo. Patients who completed treatment in the Phase 2 dose exploration study or who previously completed a prior clinical trial of nomlabofusp are eligible to screen and possibly participate in the OLE study.

In March 2024, Larimar dosed the first patient in the OLE trial, evaluating daily subcutaneous injections of 25 mg of nomlabofusp self-administered or administered by a caregiver. The OLE study will evaluate the safety and tolerability, pharmacokinetics, and frataxin levels in peripheral tissues as well as other exploratory pharmacodynamic markers (lipid profiles and gene expression data) following long-term subcutaneous administration of nomlabofusp. In addition, following the completion of enrollment, as well as at least one participant completing one year of dosing, clinical assessments collected during the study will be compared to data from a matched control arm derived from participants in the Friedreich’s Ataxia Clinical Outcome Measures Study ("FACOMS") database.

On May 30, 2024, Larimar announced that the FDA's Center for Drug Evaluation and Research ("CDER") had selected nomlabofusp as one of a few programs for participation in the Support for Clinical Trials Advancing Rare Disease Therapeutics ("START") Pilot Program. The objective of the program is to accelerate the development of drugs for rare diseases that lead to significant disability or death by facilitating frequent advice and regular communication with the FDA staff to expedite the review process of biologics and drugs.

In September 2024, the Company received access to the Medicines and Healthcare Regulatory Agency ("MHRA”) Innovative Licensing and Access Pathway (“ILAP”) for the treatment of adults and children with FA. The ILAP is facilitating patient access to novel treatments by accelerating time to market through opportunities for enhanced engagements with UK regulatory authorities and other stakeholders. Along with the receipt of the ILAP designation, nomlabofusp has already been granted orphan drug designations in the U.S. and the European Union (the “EU”), and access to the PRIME scheme in the EU.

In December 2024, the Company reported positive initial data from the ongoing OLE study. This data included safety, FXN levels, clinical, pharmacokinetic data and dose escalation:

•

Nomlabofusp was generally well tolerated for up to 260 days in subjects. The most common adverse events were injection site reactions, with most being mild, brief in duration, and self-limited. Two participants had serious adverse events (one seizure and one anaphylactic reaction) that resolved within 24 hours and withdrew from the study;

•

Long-term 25 mg tissue FXN levels showed positive mean change from baseline of 1.32 pg/μg in buccal cells and 9.28 pg/μg in skin cells at Day 90 and that 25 mg of nomlabofusp increased and maintained tissue FXN levels over time, increasing from a mean level of 15% of HV at baseline to 30% in buccal cells and from 16% to 72% in skin cells at Day 90;

•

•

Early clinical data showed trends toward improvement across a number of clinical outcomes for long-term 25 mg daily nomlabofusp including: (1) decreased values indicating early trends towards improvement in the Modified Friedreich Ataxia Rating Scale (mFARS) and the FARS-Activities of Daily Living ("ADL"), Modified Fatigue Impact Scale and 9 hole peg test at 90 days relative to baseline;

•

Key pharmacokinetic data showed rapid absorption after subcutaneous administration with exposure appearing to reach steady state in plasma by day 30 with no further accumulation, which is consistent with data from our Phase 1 and Phase 2 studies.

Also in December 2024, Larimar announced that it was increasing the dose in the OLE to 50 mg of nomlabofusp daily for then currently enrolled and all future OLE study participants. In March 2025, the Company announced that its Safety Monitoring Team has deemed anaphylaxis as an adverse drug reaction likely associated with nomlabofusp and therefore, Larimar expects to see additional reactions. To reduce the risk of allergic reactions, including anaphylaxis, Larimar amended the OLE protocol to administer premedication for the first month of dosing. The OLE study is ongoing with seven sites activated and participants continuing to enroll. All study participants are currently receiving the 50 mg dose of nomlabofusp. The Company plans to provide an update on OLE data on at least 30 to 40 study participants, some of whom have been receiving nomlabofusp for more than a year, in September 2025.

In January 2025, Larimar initiated dosing of adolescents (12-17 years old) in a PK run-in study for pediatric patients with FA. Study participants in the PK run-in study are randomized 2:1 to receive either nomlabofusp at a weight-base dose expected to match the PK of adults receiving the 50 mg dose, or placebo, daily for seven days. Following assessment of safety and PK data, participants will be eligible to screen for the OLE study. The data from this cohort is expected to be presented during the nomlabofusp program update in September 2025.

In March 2025, Larimar announced that FDA stated in written correspondence associated with a meeting through the START pilot program that they are open to considering the use of FXN concentration as a reasonably likely surrogate endpoint (“RLSE”) and the acceptability of FXN’s use as an RLSE would ultimately be a matter of review of the data in a future marketing application. FDA recommended focusing on assessments of skin FXN concentrations rather than buccal FXN concentrations due to more consistent sampling and less variability. FDA acknowledged that data the Company recently submitted appear to support a relationship between increased FXN concentrations in skin cells and relevant tissues such as the heart, dorsal root ganglion and skeletal muscle. FDA also acknowledged that the nonclinical studies Larimar submitted were performed at relevant human doses. FDA also suggested that Larimar consider exploring the relationship between increases in FXN in skin and changes in pharmacodynamic (PD) markers such as lipid profiles and/or clinical measures to provide additional support for the use of FXN as an RLSE. Larimar plans to continue discussions with FDA regarding the adequacy of the safety data set for a BLA submission seeking accelerated approval targeted for year-end 2025.

Additionally, the Company has obtained feedback from both FDA and EMA on the global Phase 3 study protocol and is on track to initiate the study by mid-2025 with potential sites in the U.S., E.U., U.K, Canada, and Australia.

The Company is subject to risks and uncertainties common to pre-commercial companies in the biotechnology industry, including, but not limited to, development and commercialization by competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, compliance with governmental regulations, failure to secure regulatory approval for its drug candidates or any other product candidates and the ability to secure additional capital to fund its operations. Product candidates under development will require extensive non-clinical and clinical testing and regulatory approval prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel, infrastructure and extensive compliance-reporting capabilities. Even if the Company's drug development efforts are successful, it is uncertain when, if ever, it will realize significant revenue from product sales.

Basis of Presentation

The consolidated financial statements include the accounts of Larimar and its wholly owned subsidiary. All intercompany balances and transactions have been eliminated. The accompanying consolidated financial statements have been prepared in conformity with U. S. Generally Accepted Accounting Principles ("GAAP").

Liquidity and Capital Resources

The Company’s consolidated financial statements have been presented on the basis that it will continue as a going concern, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business.

Since its inception, the Company has incurred significant recurring operating losses and negative cash flows from operations. The Company has incurred net losses of$80.6 million and$36.9 million for the years ended December 31, 2024, and 2023, respectively, and cash flow used in operations of$70.8 million and$33.5 million for the years ended December 31, 2024 and 2023, respectively. In addition, as of December 31, 2024, the Company had an accumulated deficit of$269.2 million. The Company expects to continue to generate operating losses for the foreseeable future. As of December 31, 2024, the Company had approximately$183.5 million of cash, cash equivalents and marketable securities available for use to fund its operations and capital requirements.

The Company has funded its operations to date primarily with proceeds from sales of common stock and proceeds from the sale of prefunded warrants for the purchase of common stock, the acquisition in 2020 of cash, cash equivalents and marketable securities upon the merger with Zafgen, Inc. ("Zafgen") and, prior to the 2020 merger with Zafgen, capital contributions from Chondrial Holdings, LLC.

In February 2024, the Company sold 19,736,842 shares of its common stock in an underwritten public offering at a price of $8.74 per share and received net proceeds of approximately $161.8 million.

In accordance with Accounting Standards Codification (“ASC”) 205, "Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern", the Company has evaluated whether there are certain conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that these consolidated financial statements are issued. As of the issuance date of these consolidated financial statements, the Company expects its cash, cash equivalents and marketable securities will be sufficient to fund its forecasted operating expenses and capital expenditure requirements into the second quarter of 2026.

The Company has not yet commercialized any products and does not expect to generate revenue from the commercial sale of any products for several years, if at all. The Company expects that its research and development and general and administrative expenses will continue to increase and, as a result, that it will need additional capital to fund its future operating and capital requirements. Unless and until the Company can generate substantial revenue, management continuously evaluates different strategies to obtain the required funding for future operations. These strategies include seeking additional funding through a combination of public or private equity offerings, debt or royalty financings, collaborations and licensing arrangements, strategic partnerships with pharmaceutical and/or larger biotechnology companies, or other sources. The incurrence of indebtedness would result in increased payment obligations and the Company may be required to agree to certain restrictive covenants, such as limitations on its ability to incur additional debt, limitations on its ability to acquire, sell or license intellectual property rights, minimum required cash balances and other operating restrictions that could adversely impact the Company's ability to conduct its business. Any additional fundraising efforts may divert the Company's management from their day-to-day activities, which may adversely affect its ability to develop and commercialize its product candidates.

There can be no assurance that the Company will be able to raise sufficient additional capital on acceptable terms, if at all. If such additional financing is not available on satisfactory terms, or is not available in sufficient amounts, or if the Company does not have sufficient authorized shares, the Company may be required to delay, limit, or eliminate the development of business opportunities and its ability to achieve its business objectives, its competitiveness, and its business, financial condition, and results of operations will be materially adversely affected. The Company could also be required to seek funds through arrangements with collaborative partners or otherwise at an earlier stage than otherwise would be desirable and it may be required to relinquish rights to some of its technologies or product candidates or otherwise agree to terms unfavorable to it, any of which may have a material adverse effect on the Company's business, operating results and prospects. In addition, geopolitical tensions, volatility of capital markets, and other adverse macroeconomic events, including those due to inflationary pressures, rising interest rates, bank instability and the ability of the U.S. government to manage federal debt limits as well as the potential impact of other health crises on the global financial markets may reduce the Company's ability to access capital, which could negatively affect its liquidity and ability to continue as a going concern.

If the Company is unable to obtain sufficient funding when needed and/or on acceptable terms, the Company may be required to significantly curtail, delay or discontinue one or more of its research and development programs, the manufacture of clinical and commercial supplies, product portfolio expansion, pre commercialization efforts and/or commercial operations, which could adversely affect its business prospects, or the Company may be unable to continue operations. If the timing of the Company's clinical assumptions are delayed or if there are other forecasted assumption changes that negatively impact its operating plan, the Company would reduce expenditures in order to further extend cash resources.

Summary of Significant Accounting Policies

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. This process involves reviewing open contracts and purchase orders, communicating with our personnel and outside vendors to identify services that have been performed on our behalf and estimating the level of service performed and the associated costs incurred for the services when we have not yet been invoiced or otherwise notified of the actual costs. Significant estimates and assumptions reflected in these consolidated financial statements include, but are not limited to, the accrual of research and development expense, the recording as prepaid expense of payments made in advance of the actual provision of goods or services, valuation of stock-based awards and valuation of leases. Due to inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in these estimates. On an ongoing basis, the Company evaluates its estimates and assumptions.

Concentrations of Credit Risk and Significant Suppliers

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash, cash equivalents and marketable securities. Cash balances may be held in financial institutions which may exceed federally insured limits. The Company has not experienced realized losses related to its cash, cash equivalents or marketable securities.

The Company is highly dependent on third-party manufacturers to supply products for research and development activities in its programs, to scale and optimize their manufacturing processes and, ultimately, to provide commercial supply. The Company relies and expects to continue to rely on a small number of manufacturers to supply it with its requirements for drug substance and formulated drugs related to these programs. The drug substance which is in frozen liquid form for nomlabofusp is currently manufactured for the Company by a third-party manufacturer, and the frozen liquid form of drug product is made at another manufacturer. The Company is undertaking a program with a third manufacturer to begin to produce a lyophilized version of the drug product from the same drug substance, that, once available, the Company intends to use in certain of its future planned clinical trials. The Company’s research and development programs could be adversely affected by a significant interruption in these manufacturing services or in the supply of drug substance and formulated drugs.

Cash and Cash Equivalents

The Company considers all highly liquid investments with maturities of three months or less at the date of purchase to be cash equivalents. Cash equivalents consisted of money market funds as of December 31, 2024 and 2023.

Marketable securities

Marketable securities consist of debt investments with original maturities greater than ninety days. The Company classifies its marketable securities as available-for-sale. Accordingly, these investments are recorded at fair value, which is based on quoted market prices. When the fair value is below the amortized cost the amount of the expected credit loss is estimated. The credit-related impairment amount, if any, would be recognized in net income; the remaining impairment amount and unrealized gains are reported as a component of accumulated other comprehensive income in stockholders’ equity. Credit losses, if any, are recognized through the use of an allowance for credit losses account and subsequent improvements in expected credit losses are recognized as a reversal of the allowance account. If the Company has the intent to sell the security or if it is more likely than not that the Company would be required to sell the security prior to recovery of its amortized cost basis, the allowance for credit loss would be written off and the excess of the amortized cost basis of the asset over its fair value would be recorded in net income.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. Depreciation expense is recognized using the straight-line method over afive or seven-year estimated useful life for equipment, furniture and fixtures and office equipment. Leasehold improvements are amortized over the shorter of the asset life or the term of the lease agreement. Expenditures for repairs and maintenance of assets are charged to expense as incurred. Upon retirement or sale, the cost and related accumulated depreciation of assets disposed of are removed from the accounts and any resulting gain or loss is included in loss from operations.

Impairment of Long-Lived Assets

Long-lived assets consist of property and equipment, net¸ and right-of-use assets. Long-lived assets to be held and used are tested for recoverability whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. Factors that the Company considers 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. If an impairment review is performed to evaluate a long-lived asset for recoverability, the Company compares forecasts of undiscounted cash flows expected to result from the use and eventual disposition of the long-lived asset to its carrying value. Any impairment loss, if indicated, is measured as the amount by which the carrying amount of the asset exceeds the estimated fair value of the asset.

Research and Development Costs

Costs associated with internal research and development and external research and development services, including drug manufacturing and scale- up, other drug development and testing costs, clinical studies and non-clinical studies, are expensed as incurred. Research and development expenses include costs for salaries, employee benefits, subcontractors, facility-related expenses, depreciation, stock-based compensation, third-party license fees, laboratory supplies, and external costs of outside vendors engaged to conduct discovery, non-clinical and clinical development activities and clinical trials as well as to manufacture clinical trial materials and to scale up the manufacturing process, and other costs. The Company recognizes external research and development costs based on an evaluation of the progress to completion of specific tasks using information provided to the Company by its key service providers.

Nonrefundable advance payments for goods or services to be received in the future for use in research and development activities are recorded as prepaid expenses. Such prepaid expenses are recognized as an expense when the goods have been delivered or the related services have been performed, or when it is no longer expected that the goods will be delivered, or the services rendered.

Upfront payments, milestone payments and annual maintenance fees under license agreements are currently expensed in the period in which they are incurred.

Patent Costs

All patent-related costs incurred in connection with filing and prosecuting patent applications are expensed as incurred due to the uncertainty about the recovery of the expenditure. Amounts incurred are classified as general and administrative expenses.

Stock-Based Compensation

The Company measures all stock-based awards granted to employees and directors based on the fair value on the date of grant using the Black-Scholes option-pricing model. Compensation expense of those awards is recognized over the requisite service period, which is the vesting period of the respective award. Typically, the Company issues awards with only service-based vesting conditions and records the expense for these awards using the straight-line method. The Company accounts for forfeitures as they occur.

The Company classifies stock-based compensation expense in its consolidated statements of operations and comprehensive loss in the same manner in which the award recipient’s payroll costs are classified or in which the award recipient’s service payments are classified.

Prior to May 28, 2020, the Company had been a private company and lacked company-specific historical and implied volatility information for its common stock. Prior to January 1, 2023, the Company estimated its expected common stock price volatility solely based on the historical volatility of publicly traded peer companies. Beginning on January 1, 2023, based on the availability of sufficient historical trading data of the Company's own common stock on the Nasdaq Global Market to calculate accurately its volatility, the Company began blending its volatility starting from June 2020 (following its merger with Zafgen in 2020) to the date of each stock-based award, and weighing the volatility of its peer group for the amount of time from May 31, 2020 backwards so that the blended volatility equals the expected term of the related stock-based award. The expected term of the Company’s stock options has been determined utilizing the “simplified” method for awards that qualify as “plain-vanilla” options. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. The expected dividend yield considers the fact that the Company has never paid cash dividends on common stock and does not expect to pay any cash dividends in the foreseeable future.

Segment Information

Operating segments are defined as components of an enterprise for which separate discrete information is available for evaluation by the chief operating decision maker, or decision making group, in deciding how to allocate resources in assessing performance. The Company is managed on a consolidated basis and hasone operating and reportable segment related to the development of clinical and preclinical product candidates for the development of the Company’s proprietary new therapies, primarily nomlabofusp, the Company's life science segment. The Company’s chief operating decision maker (“CODM”) is the Company'schief executive officer ("CEO").

The accounting policies of the life science segment are the same as those described in the summary of significant accounting policies. The CODM assesses performance for the Company and its reportable segment based on net loss, which is reported on the consolidated Statements of Operations. The measure of segment assets is reported on the balance sheet as total consolidated assets. All long-lived assets are located in the U.S.

To date, the Company has not generated any product revenue. The Company expects to continue to incur significant expenses and operating losses for the foreseeable future as it advances product candidates through all stages of development and clinical trials and regulatory approval.

The CODM uses consolidated financial information, including consolidated net loss, to evaluate performance, forecast future period financial results, allocate resources for the company by, among other things, comparing budgeted to actual results.

The table below summarizes the significant expense categories regularly reviewed by the CODM for thetwelve months ended December 31, 2024 and 2023:

Income Taxes

The Company accounts for income taxes using 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 recognized in the consolidated financial statements or in the Company’s tax returns. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Changes in deferred tax assets and liabilities are recorded in the provision for income taxes. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent it believes, based upon the weight of available evidence, that it is more likely than not that all or a portion of the deferred tax assets will not be realized, a valuation allowance is established through a charge to income tax expense. Potential for recovery of deferred tax assets is evaluated by estimating the future taxable profits expected and considering prudent and feasible tax planning strategies.

The Company accounts for uncertainty in income taxes recognized in the consolidated financial statements by applying a two-step process to determine the amount of tax benefit to be recognized. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination by the taxing authorities. If the tax position is deemed more-likely-than-not to be sustained, the tax position is then assessed to determine the amount of benefit to recognize in the consolidated financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. The provision for income taxes includes the effects of any resulting tax reserves, or unrecognized tax benefits, that are considered appropriate as well as the related net interest and penalties.

Comprehensive Gain (Loss)

Comprehensive gain (loss) includes net loss as well as other changes in stockholders’ equity that result from transactions and economic events other than those with stockholders. For the years ended December 31, 2024 and 2023, the Company’s only element of other comprehensive gain (loss) was unrealized gain (loss) on marketable securities.

Net Loss Per Share

Basic net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted average number of common shares outstanding for the period. Prior to August 11, 2023, basic shares outstanding includes the weighted average effect of the Company’s prefunded warrants issued in June 2020, the exercise of which requires little or no consideration for the delivery of shares of common stock. These prefunded warrants were exercised on August 11, 2023 and the Company received cash proceeds of less than $0.1 million. Accordingly, the 628,403 shares were issued upon the exercise of these warrants and are included in issued and outstanding common stock.

Diluted net loss per share attributable to common stockholders is computed by dividing the diluted net loss attributable to common stockholders by the weighted average number of common shares, including potentially dilutive common stock equivalents assuming the dilutive effect of outstanding stock options, outstanding restricted stock units, and unvested restricted common shares, as determined using the treasury stock method. For periods in which the Company has reported net losses (all periods since inception), diluted net loss per common share attributable to common stockholders is the same as basic net loss per common share attributable to common stockholders, since dilutive common stock equivalents are not assumed to have been issued if their effect is antidilutive.

The Company excluded 7,135,390 and 4,888,502 options to purchase common stock, outstanding as of December 31, 2024 and 2023 respectively, from the computation of diluted net loss per share for the twelve months ended December 31, 2024 and 2023, respectively, because they had an anti-dilutive impact due to the net loss incurred for the periods.

Recently Issued and Adopted Accounting Pronouncements

From time to time, new accounting guidance is issued by the FASB or other standard setting bodies that is adopted by us as of the effective date or, in some cases where early adoption is permitted, in advance of the effective date. We have assessed the recently issued guidance that is not yet effective and believe the new guidance will not have a material impact on the consolidated results of operations, cash flows or financial position.

In November 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”). ASU 2023-07 requires disclosure of incremental segment information on an annual and interim basis. The amendments also require companies with a single reportable segment to provide all disclosures required by this amendment and all existing segment disclosures in ASC 280, Segment Reporting. The amendments are effective for fiscal years beginning after December 15, 2023, and interim periods beginning after December 15, 2024. The Company adopted ASU 2023-07, effective December 31, 2024, in these consolidated financial statements. ASU 2023-07 only impacted the disclosures and did not impact the consolidated financial statements. See Note 2, Segment Information, for disclosures related to the adoption of ASU 2023-07.

Recently Issued Accounting Pronouncements Not Yet Adopted

In December 2023, the FASB issued ASU No. 2023-09, “Improvements to Income Tax Disclosures (Topic 740),” which requires entities to disclose in their rate reconciliation table additional categories of information about federal, state and foreign income taxes as well as additional information about reconciling items if certain quantitative thresholds are met. This ASU will require all entities to disclose income taxes paid, net of refunds, disaggregated by federal (national), state and foreign taxes for annual periods and to disaggregate the information by jurisdiction based on a quantitative threshold. All entities are required to apply the guidance prospectively, with the option to apply it retrospectively. The ASU is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company has determined it will adopt this ASU on January 1, 2025, the adoption of which is not expected to have a material impact on the Company’s consolidated results of operations or cash flows.

In November 2024, the FASB issued ASU 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses”, which requires disaggregated disclosures in the notes of the financial statements of certain categories of expenses that are included in expense line items on the face of the income statement. This ASU is effective for annual periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company will evaluate the impact adopting ASU 2024-03 will have on the Company's consolidated financial statements and disclosures.

Fair Value Measurements and Cash Equivalents/Marketable Securities

Fair Value Measurements

The Company’s assets and liabilities that are measured at fair value on a recurring basis as of December 31, 2024 and December 31, 2023 are measured in accordance with the standards of ASC 820, Fair Value Measurements and Disclosures, which establishes a three-level valuation hierarchy for measuring fair value and expands financial statement disclosures about fair value measurements. The valuation hierarchy is based on upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows:

The Company’s financial instruments consist primarily of cash and cash equivalents, marketable securities, accounts payable and accrued liabilities. For accounts payable and accrued liabilities, the carrying amounts of these financial instruments as of December 31, 2024 and 2023 were considered representative of their fair values due to their short term to maturity.

The following tables summarize the Company’s cash equivalents and marketable securities as of December 31, 2024 and 2023:

The accrued interest receivable related to the Company’s investments was $1.1 million and $0.3 million as of December 31, 2024 and 2023, respectively, and is included in prepaid expenses and other current assets on the consolidated balance sheet.

The Company classifies its money market funds and U.S. treasury bills, which are valued based on quoted market prices in active markets with no valuation adjustment, as Level 1 assets within the fair value hierarchy.

The Company classifies its investments in U.S. government and agency securities, corporate commercial paper, and corporate bonds, if any, as Level 2 assets within the fair value hierarchy. The fair values of these investments are estimated by taking into consideration valuations obtained from third-party pricing services. The pricing services utilize industry standard valuation models, including both income- and market-based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. These inputs include reported trades of and broker/dealer quotes on the same or similar securities, issuer credit spreads, benchmark securities, prepayment/default projections based on historical data and other observable inputs.

As of December 31, 2024, the unrealized loss for available-for-sale investments were non-credit related, and the Company does not intend to sell the investments that were in an unrealized loss position, nor will it be required to sell those investments before recovery of their amortized cost basis, which may be maturity. As of December 31, 2024 and 2023, no allowances for credit losses for the Company’s investments were recorded. During thetwelve months ended December 31, 2024 and 2023, the Company didnot recognize any impairment losses related to investments.

As of December 31, 2024 and 2023, the Company's cash equivalents and marketable securities consisted of a U.S. government money market fund, U.S. Treasury Bills and U.S. government and agency securities, all held in our name in a separate custody account with U.S. Bank. The U.S. government money market fund has same-day liquidity access and the U.S. government and agency securities all have maturities of 360 days or less.

Marketable Securities

The following tables summarize the Company’s marketable securities as of December 31, 2024 and 2023:

Prepaid Expenses and Other Current Assets

Prepaid expenses and other current assets consisted of the following:

The lease extension on the original 4,642 square footage commenced on September 1, 2023 and the Company recorded a right of use asset and lease liability of $0.5 million as of that date.

The new lease on 3,462 additional square footage commenced on October 1, 2023 and the Company recorded a right of use asset and lease liability of $0.3 million as of that date.

The right of use assets and lease liabilities with these leases are reflected in the financial statements for the year ended December 31, 2024 as are the right of use asset and lease liability of the Company's Boston office space and lab space discussed below.

Boston Office Lease

In connection with the Company's 2020 merger with Zafgen described in footnote 1, on May 28, 2020, the Company acquired a non-cancellable operating lease for approximately 17,705 square feet of office space (the “Premises”). The lease expires on October 30, 2029. As part of the agreement, the Company was initially required to maintain a letter of credit, of $1.3 million. In October of 2024, upon the agreement with the landlord that we had achieved certain clinical development milestones required in the lease, this letter of credit was reduced to $0.6 million. During both periods presented, this cash deposit and is classified as restricted cash within the consolidated financial statements. In addition to the base rent, the Company is also responsible for its share of operating expenses, electricity and real estate taxes, which costs are not included in the determination of the leases’ right-of-use assets or lease liabilities. The right-of-use asset is being amortized to other income/(expense) over the remaining lease term as a result of the sublease described below.

On October 27, 2020, the Company entered into a sublease agreement (the “Sublease”) with Massachusetts Municipal Association, Inc. (the “Subtenant”), whereby the Company sublet the entire Premises to the Subtenant. The initial term of the Sublease commenced on December 4, 2020 and continues until October 30, 2029. In connection with the Sublease, the Company evaluated the need for impairment under ASC 360 "Impairment Testing: Long-Lived Assets Classified as Held and Used," and determined there was no impairment.

The Sublease provided for an initial annual base rent of $0.8 million, which increases annually up to a maximum annual base rent of $1.0 million. The Subtenant also is responsible for paying to the Company future increases in operating costs (commencing on January 1, 2022), future increases in annual tax costs (commencing July 1, 2021) and all utility costs (commencing March 1, 2021) attributable to the Premises during the term of the Sublease. As part of the Sublease, the subtenant deposited a letter of credit in the amount of $0.8 million to assure their performance under the sublease. If there are no uncured events of default under the sublease, the amount of this security deposit decreases over time to $0.4 million on the sixth anniversary of the Sublease. The Company records sublease income on this sublease on a straight-line basis as a component of other income/(expense).

Income Taxes

During the years ended December 31, 2024, and 2023, the Company recordedno income tax benefits for the net operating losses incurred in each year due to its uncertainty of realizing a benefit from those items.

The domestic and foreign components of loss before income taxes are as follows.

A reconciliation of the U.S. federal statutory income tax rate to the Company’s effective income tax rate is as follows:

Net deferred tax assets as of December 31, 2024 and 2023 consisted of the following:

Changes in the valuation allowance for deferred tax assets during the year ended December 31, 2024 and 2023 related primarily to the increase in net operating loss carryforwards and tax credit carryforwards and a decrease other deferred tax assets associated with a reduction in the Company’s effective state rate. Changes to the valuation allowance were as follows:

As of December 31, 2024, the Company had net operating loss carryforwards that expire for federal, foreign and state income tax purposes of $198.2 million, $1.2 million and $164.5 million, respectively. The federal and state operating losses begin to expire in 2026 and 2030, while the foreign net loss carryforward can be carried forward indefinitely. As of December 31, 2024, the Company had federal net operating loss carryforwards that were generated after December 31, 2017 of $159.5 million that do not expire, however these carryforwards are limited to 80% of the taxable income in any one tax period. As of December 31, 2024, the Company also had available tax credit carryforwards for federal and state income tax purposes of $28.0 million which begin to expire in 2039. Utilization of the pre-Merger net operating loss carryforwards attributable to Zafgen, of approximately $33.5 million, are subject to a substantial annual limitation under Section 382 of the Internal Revenue Code of 1986 due to ownership changes occurred during the tax year associated with the Merger. In addition to the limitation of the pre-Merger NOL’s of Zafgen, the net capitalized R&D deferred tax assets in the amount of $66.9 millionis subject to the built-in loss rules under Section 382 and may not be realized if the underlying asset associated with the R&D is disposed within five years of the Merger, or May 28, 2025. In general, an ownership change, as defined by Section 382, results from transactions increasing the ownership of certain stockholders or public groups in the stock of a corporation by more than 50% over a three-year period. The ownership changes will limit the amount of pre-merger Zafgen carryforwards that can be utilized annually to offset future taxable income with an annual limitation of approximately $35 thousand per year. The Company has reduced their NOL and R&D tax credit deferred tax assets associated with the pre-Merger Zafgen operations as a result of the 382 analysis.

The Company believes that as a result of its merger with Zafgen, its ability to utilize NOLs acquired in the transaction and our other NOLs is expected to be severely limited by Section 382 of the Code. Additionally, the Company’s July 2021, September 2022 and February 2024 equity transactions could also limit its ability to utilize NOLs in the future. The Company has not conducted a study to assess whether a change of control has occurred or whether there have been multiple changes of control since inception. If the Company experienced a change of control, as defined by Section 382, at any time since inception, utilization of its net operating loss carryforwards or tax credit carryforwards would be subject to an annual limitation under Section 382, which is determined by first multiplying the value of the Company’s stock at the time of the ownership change by the applicable long-term tax-exempt rate, and then could be subject to additional adjustments, as required. Additionally, our July 2021, September 2022 and February 2024 equity transactions could also limit our ability to utilize NOLs in the future. Any limitation may result in expiration of a portion of the net operating loss carryforwards or tax credit carryforwards before utilization. Further, until a study is completed, and any limitation is known, no amounts are being presented as an uncertain tax position.

The Tax Cuts and Jobs Act ("TCJA") requires taxpayers to capitalize and amortize research and experimental expenditures under IRC Section 174 for tax years beginning after December 31, 2021. This rule became effective for the Company during the year ended December 31, 2022 and resulted in the capitalization of research and development costsof $69.2 million, $24.5 million and $22.2 million in 2024, 2023 and 2022, respectively. The Company is amortizing these costs for tax purposes over five years if the research and development was performed in the U.S. and over 15 years if the research and development was performed outside the U.S.

As of December 31, 2024 and 2023, the Company’s net deferred tax asset balance before the valuation allowance was $173.0 million and $141.8 million, respectively, and was comprised principally of net operating loss carryforwards, capitalized research and development expenses and tax credit carryforwards. During the years ended December 31, 2024 and 2023, gross deferred tax assets increased due to deferred tax assets acquired as a result of additional net operating loss carryforwards and research and development tax credits generated.

The Company has evaluated the positive and negative evidence bearing upon its ability to realize the deferred tax assets. Management has considered the Company’s history of cumulative net losses incurred since inception and its lack of commercialization of any products or generation of any revenue from product sales since inception and has concluded that it is more likely than not that the Company will not realize the benefits of the deferred tax assets. Accordingly, a full valuation allowance has been established against the deferred tax assets as of December 31, 2024 and 2023. Management reevaluates the positive and negative evidence at each reporting period.

The Company hasnot recorded any amounts for unrecognized tax benefits as of December 31, 2024 and 2023. The Company files tax returns as prescribed by the tax laws of the jurisdictions in which it operates. In the normal course of business, the Company is subject to examination by federal and state jurisdictions, where applicable. There are currently no pending income tax examinations. The Company’s tax years are still open under statute from 2020 to the present. Earlier years may be examined to the extent that tax credit or net operating loss carryforwards are used in future periods. The Company’s policy is to record interest and penalties related to income taxes as part of its income tax provision.
