CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Statements made in this Quarterly Report on Form 10-Q that are not statements of historical or current facts are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements discuss our business, operations and financial performance and conditions, as well as our plans, objectives and expectations for our business operations and financial performance and condition. In some cases, you can identify forward-looking statements by terminology such as “aim,” “anticipate,” “assume,” “believe,” “contemplate,” “continue,” “could,” “design,” “due,” “estimate,” “expect,” “goal,” “intend,” “may,” “objective,” “plan,” “predict,” “positioned,” “potential,” “seek,” “should,” “target,” “will,” “would” and other similar expressions that are predictions of or indicate future events and future trends, or the negative of these terms or other comparable terminology. In addition, statements that “we believe” or similar statements reflect our beliefs and opinions on the relevant subject only. These forward-looking statements, which are subject to risks, uncertainties and assumptions about us, may include projections of our future financial performance, our anticipated growth strategies and anticipated trends in our business.

You should understand that the following important factors could affect our future results and could cause those results or other outcomes to differ materially from those expressed or implied in our forward-looking statements:

•our ability to successfully engage with, and satisfactorily respond to, requests for additional information from the U.S. Food and Drug Administration ("FDA") concerning the clinical hold on our investigational new drug application ("IND") for CTI-1601 and the timing and outcomes of such interactions, including our plans to engage the FDA in order to lift the clinical hold, in full or in part, and allow re-initiation of interventional clinical studies;

•uncertainties in obtaining successful non-clinical or clinical results that reliably and meaningfully demonstrate safety, tolerability and efficacy profiles that are satisfactory to the FDA, European Medicines Agency ("EMA") and other comparable regulatory authorities for marketing approval for CTI-1601 or any other product candidate that we may develop in the future and unexpected costs that may result therefrom;

•delays or changes in our anticipated clinical timelines, including as a result of patient recruitment, clinical and non-clinical results, changes in clinical protocols, regulatory restrictions, including clinical holds, and milestones for CTI-1601, including those associated with COVID-19 and the efforts to mitigate it;

•uncertainties associated with the clinical development and regulatory approval for CTI-1601 or any other product candidate that we may develop in the future, including potential delays in the commencement, enrollment and completion of clinical trials;

•the difficulties and expenses associated with obtaining and maintaining regulatory approval for CTI-1601 or any other product candidate we may develop in the future, and the indication and labeling under any such approval;

•our estimates regarding future results of operations, financial position, research and development costs, capital requirements and our needs for additional financing;

•how long we can continue to fund our operations with our existing cash, cash equivalents and marketable debt securities;

•our ability, and the ability of third-party manufacturers we engage, to optimize and scale CTI-1601 or any other product candidate’s manufacturing process and to manufacture sufficient quantities of clinical supplies, if the clinical hold on the CTI-1601 IND is lifted, and, if approved, commercial supplies of CTI-1601;

•our ability to realize any value from CTI-1601 and any other product candidate we may develop in the future in light of inherent risks and difficulties involved in successfully bringing product candidates to market and the risk that the product candidates, if approved, will not achieve broad market acceptance;

•our ability to comply with regulatory requirements applicable to our business and other regulatory developments in the United States and other countries;

•the size and growth of the potential markets for CTI-1601 or any other product candidate that we may develop in the future, the rate and degree of market acceptance of CTI-1601 or any other product candidate, if approved, that we may develop in the future and our ability to serve those markets;

•Competing therapies and products including those that are still in clinical development which become available via marketing authorizations or compassionate use and their impact on our ability to recruit and retain clinical trial patients, to obtain and maintain potential expedited regulatory pathways, and to commercialize current and future product candidates, if approved, (including the impact of potential barriers to entry if a competitor is able to establish a strong market position before we are able to commercialize our products);

•our ability to obtain and maintain patent protection and defend our intellectual property rights against third-parties;

•the performance of third parties upon which we depend, including third-party contract research organizations ("CROs") and third-party suppliers, manufacturers, distributors, and logistics providers;

•our ability to maintain our relationships, and contracts with our key vendors;

•our ability to recruit or retain key scientific, technical, commercial, and management personnel and to retain our executive officers;

•our ability to maintain proper functionality and security of our internal computer and information systems and prevent or avoid cyber-attacks, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption; and

•the extent to which health epidemics, unforeseen emergencies and other outbreaks of communicable diseases, including the ongoing COVID-19 pandemic and the efforts to mitigate it, geopolitical turmoil, including the ongoing invasion of Ukraine by Russia or increased trade restrictions between the United States, Russia, China, and other countries, social unrest, political instability, terrorism or other acts of war could disrupt our operations, the operations of third parties on which we rely or the operations of regulatory agencies we interact with in the development of CTI-1601.

These forward-looking statements are based on management’s current expectations, estimates, forecasts and projections about our business and the industry in which we operate, and management’s beliefs and assumptions are not guarantees of future performance or development and involve known and unknown risks, uncertainties and other factors that are in some cases beyond our control. In light of the significant uncertainties in these forward-looking statements, you should not rely upon forward-looking statements as predictions of future events. Although we believe the expectations reflected in the forward-looking statements are reasonable, the future results, levels of activity, performance or events and circumstances reflected in the forward-looking statements may not be achieved or occur at all. The factors that could cause or contribute to such differences include, but are not limited to, those discussed in our Annual Report on Form 10-K filed on March 25, 2022. All forward-looking statements are applicable only as of the date on which they were made and, except as required by law, we undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise after the date of this Quarterly Report on Form 10-Q or to reflect the occurrence of any unanticipated events. Comparisons of results for current and any prior periods are not intended to express any future trends or indications of future performance, unless expressed as such, and should only be viewed as historical data.

LARIMAR THERAPEUTICS, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1.Organization, Clinical Development, Nature of the Business, COVID-19, Clinical Hold 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, 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. Friedreich’s ataxia is a rare, progressive and fatal disease in which patients are unable to produce sufficient FXN due to a genetic abnormality.

In May 2021, Larimar reported positive topline data from its Phase 1 Friedreich’s ataxia, ("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 demonstrate proof-of-concept by showing that daily subcutaneous injections of CTI-1601 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). FXN levels achieved in peripheral tissues (buccal cells) following daily 50 mg and 100 mg subcutaneous injections of CTI-1601 were at or in excess of FXN levels that would be expected in phenotypically normal heterozygous carriers. There were no serious adverse events, ("SAEs"), associated with either the MAD or SAD trials.

In May 2021, the FDA placed a clinical hold on the Company's CTI-1601 clinical program after the Company notified the agency of mortalities at the highest dose levels of the 26-week non-human primate toxicology study that was designed to support extended dosing of patients with CTI-1601. At the time the hold was placed, Larimar had no interventional clinical trials with patients enrolling or enrolled. In February 2022, in response to the Company submitting a complete response to the FDA, the Agency stated that it was maintaining the clinical hold and that additional data are needed to resolve the clinical hold. Larimar subsequently submitted a request for an FDA Type C meeting. This meeting request has been granted and is scheduled for early in the third quarter of 2022. Throughout the course of the interactions associated with the Type C meeting, Larimar intends to work with the Agency to enable resolution of the clinical hold and to agree on the study design and timing of the next proposed clinical trial. Larimar does not know when, or if the clinical hold will be lifted.

The Company is subject to risks and uncertainties common to pre-commercial companies in the biotechnology industry, including, but not limited to, development 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. Drug candidates currently 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, and infrastructure and extensive compliance-reporting capabilities. Even if our drug development efforts are successful, it is uncertain when, if ever, we will realize significant revenue from product sales.

In March 2020, the World Health Organization ("WHO"), declared the outbreak of COVID-19, a novel strain of Coronavirus, a global pandemic. The pandemic resulted in the temporary stoppage of the Company’s CTI-1601 Phase 1 clinical trials in patients with Friedreich’s ataxia in March 2020. In July 2020, the Company resumed these clinical trials, and has since completed both of the Company's SAD and MAD clinical trials. Since being discovered, new variants of COVID-19 have emerged. In November 2021, the Omicron variant was identified in South Africa, and has been deemed a variant of concern by the WHO. In addition to the Omicron variant, the WHO has deemed four other variants to be variants of concern: the Alpha variant, the Beta variant, the Gamma variant, and the Delta variant. All of the aforementioned variants have at least one of the following characteristics resulting in the WHO deeming them variants of concern: an increase in transmissibility or detrimental change in COVID-19 epidemiology, an increase in virulence or change in clinical disease presentation, or a decrease in effectiveness of public health and social measures or available diagnostics, vaccines, or therapeutics.

Vaccines manufactured by Moderna, Pfizer and Johnson & Johnson were introduced late in the fourth quarter of 2020 and became widely available by the end of the first quarter of 2021. While the vaccines have proven effective in reducing the severity and mortality of COVID-19, including the variants that have evolved to date, the overall vaccination rate has not reached the level required for herd immunity in some areas of the country. Further, additional doses of vaccines have been and may continue to be required and individuals may refuse or fail to receive one or more such doses. The incidence of variants of COVID-19 has been increasing, particularly among unvaccinated individuals, and the Omicron variant has proven to be more easily spread than earlier variants.

7

The low vaccination rate, the spread of the variants and the evolution of additional mutations against which the current vaccines may prove ineffective could again result in major disruptions to businesses and markets worldwide. Furthermore, the incidence of "breakthrough" infections even among vaccinated individuals have been increasing, resulting in the need for booster doses which could make COVID-19 a long-term infectious disease concern. The Company’s business, results of operations, financial condition and cash flows could be materially and adversely affected. Specifically, the Company could experience additional delays in future clinical trial timelines as a result of additional travel and hospital restrictions related to the COVID-19 pandemic and the efforts to mitigate it which may be imposed or could experience supply shortages or manufacturer shutdowns impacting the manufacture of drug substance or drug product, which could also impact clinical trial timelines. The condensed consolidated financial statements do not reflect any adjustments as a result of the pandemic.

Basis of Presentation

The condensed consolidated financial statements include the accounts of Larimar and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated. The accompanying condensed consolidated financial statements have been prepared in conformity with GAAP.

Going Concern Assessment

The Company’s condensed 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 $8.9 million and $12.1 million for the three months ended March 31, 2022 and 2021, respectively. In addition, as of March 31, 2022, the Company had an accumulated deficit of $125.2 million. The Company expects to continue to generate operating losses for the foreseeable future. As of March 31, 2022, the Company had approximately $62.6 million of cash and cash equivalents available for use to fund its operations and capital requirements.

In August 2020, the Company entered into an Equity Distribution Agreement (the “ATM Agreement”) with an investment bank in connection with the establishment of an “at-the-market” offering program under which the Company could sell up to an aggregate of $50,000,000 of shares of its common stock from time to time through this investment bank as sales agent. In 2021, the Company sold 2,342,720 shares pursuant to the ATM Agreement for gross proceeds of $20.5 million. As of May 10, 2022, $29.2 million of additional shares of common stock remained available for sale by the Company under the ATM Agreement. See Note 7 for a further discussion of the ATM Agreement.

In accordance with Accounting Standards Update (“ASU”) No. 2014-15, 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 the consolidated financial statements are issued. As of the issuance date of these condensed consolidated financial statements, the Company expects its cash and cash equivalents will be sufficient to fund its forecasted operating expenses and capital expenditure requirements, for at least the next twelve months from the issuance of these financial statements. If the timing of our clinical assumptions were delayed or if there were other forecasted assumption changes that negatively impact our operating plan, the Company could reduce expenditures in order to further extend cash resources.

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, will need additional capital to fund its future operating and capital requirements. Management is currently evaluating different strategies to obtain the required funding for future operations. Until the Company can generate substantial revenue, if ever, the Company expects to seek additional funding through a combination of public or private equity offerings, debt financings, collaborations and licensing arrangements or other sources. The incurrence of indebtedness would result in increased fixed 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 and other operating restrictions that could adversely impact the Company's ability to conduct our 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 our product candidates.

8

There can be no assurance that the Company will be able to raise sufficient additional capital on acceptable terms or at all. If such additional financing is not available on satisfactory terms, or is not available in sufficient amounts, or 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 unrest including the potential impact of the Russian invasion of Ukraine, the possibility that the conflict could expand beyond eastern Europe, the impact of the COVID-19 pandemic and/or 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 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 or pre commercialization efforts, which could adversely affect its business prospects, or the Company may be unable to continue operations.

2.Summary of Significant Accounting Policies

Unaudited Interim Financial Information

The condensed consolidated balance sheet as of December 31, 2021 was derived from the Company’s audited financial statements but does not include all disclosures required by GAAP. The accompanying unaudited condensed consolidated financial statements as of March 31, 2022 and for the three months ended March 31, 2022 and 2021, have been prepared by the Company, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”), for interim financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto for the year ended December 31, 2021 included in the Company’s Annual Report on Form 10-K filed on March 25, 2022.

In the opinion of management, all adjustments, consisting only of normal recurring adjustments necessary for a fair statement of the Company’s condensed consolidated financial position as of March 31, 2022 and condensed consolidated results of operations and cash flows for the three months ended March 31, 2022 and 2021 have been made. The results of operations for the three months ended March 31, 2022 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2022.

Use of Estimates

The preparation of 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. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, the accrual of research and development expense, 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.

Research and Development Costs

Costs associated with internal research and development and external research and development services, including drug development, 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 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 service providers.

9

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, non-employee consultants 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 and market-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 condensed 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 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. Therefore, the Company estimates its expected common stock price volatility based on the historical volatility of publicly traded peer companies and expects to continue to do so until it has adequate historical data regarding the volatility of its own traded stock price. 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. 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.

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. 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. Basic and diluted weighted average shares of common stock outstanding for the three months ended March 31, 2022 and 2021 includes the weighted average effect of 628,403 prefunded warrants for the purchase of shares of common stock, for which the remaining unfunded exercise price is $0.01 per share.

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 shares assuming the dilutive effect of outstanding stock options and unvested restricted common shares, as determined using the treasury stock method. For periods in which the Company has reported net losses, 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 shares are not assumed to have been issued if their effect is antidilutive.

The Company excluded 3,078,511 and 2,397,152 common stock equivalents outstanding as of March 31, 2022 and 2021, respectively, from the computation of diluted net loss per share for the three months ended March 31, 2022 and 2021 because they had an anti-dilutive impact due to the net loss incurred for the periods presented.

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 condensed consolidated results of operations, cash flows or financial position.

3.Fair Value Measurements and Marketable Debt Securities

Fair Value Measurements

The Company’s assets and liabilities that are measured at fair value on a recurring basis as of March 31, 2022 and December 31, 2021 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 the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows:

Level – 1	Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.
Level – 2	Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.
Level – 3	Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

The Company’s financial instruments consist primarily of cash, cash equivalents, marketable debt securities, accounts payable and accrued liabilities. For accounts payable and accrued liabilities, the carrying amounts of these financial instruments as of March 31, 2022 and December 31, 2021 were considered representative of their fair values due to their short term to maturity.

The following tables summarize the Company’s cash equivalents as of March 31, 2022 and December 31, 2021:

	Total		Quoted Prices in Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

7.Stockholders’ Equity and Stock Options

Common Stock and Prefunded warrants

As of March 31, 2022, the Company’s Certificate of Incorporation, as amended and restated, authorized the Company to issue up to 115,000,000 shares of $0.001 par value common stock, of which 17,710,450 shares were issued and outstanding, and up to 5,000,000 shares of $0.001 par value undesignated preferred stock, of which no shares were issued or outstanding. The voting, dividend, and liquidation rights of the holders of the Company’s common stock are subject to and qualified by the rights, powers, and preferences of the holders of the preferred stock. Each share of common stock entitles the holder to one vote on all matters submitted to a vote of the Company’s stockholders. Common stockholders are entitled to receive dividends, as may be declared by the board of directors of the Company (the “Board”), if any. No cash dividends have been declared or paid to date.

Equity Distribution Agreement

On August 14, 2020, the Company entered into the ATM Agreement with an investment bank in connection with the establishment of an “at-the-market” offering program under which the Company may sell up to an aggregate of $50,000,000 of shares of common stock (the “ATM Shares”) from time to time (the “Offering”).

Under the ATM Agreement, the Company sets the parameters for the sale of ATM Shares, including the number of ATM Shares to be issued, the time period during which sales are requested to be made, limitations on the number of ATM Shares that may be sold in any one trading day and any minimum price below which sales may not be made. Sales of the ATM Shares, if any, under the ATM Agreement may be made in transactions that are deemed to be “at-the-market offerings” as defined in Rule 415 under the Securities Act. The Company pays its investment bank a commission equal to 3.0% of the gross proceeds of any ATM Shares sold through its investment bank under the ATM Agreement and reimburses the investment bank for certain specified expenses. The ATM Agreement contains customary representations, warranties and agreements by the Company, indemnification obligations of the Company and its investment bank, other customary obligations of the parties and termination provisions. The Company has no obligation to sell any of the ATM Shares and may at any time suspend offers under the ATM Agreement.

In 2021, the Company sold 2,342,720 shares under the ATM Agreement for net proceeds of $19.9 million.

As of March 31, 2022, 2,354,244 shares of Common Stock have been sold under the ATM Agreement for net proceeds of $20.1 million. As of May 10, 2022, approximately $29.2 million shares of common stock still remained available for sale by the Company under the ATM Agreement.

2020 Equity Incentive Plan

The Board adopted the 2020 Equity Incentive Plan (the "2020 Plan") on July 16, 2020 and the stockholders of the Company approved the 2020 Plan on September 29, 2020. The 2020 Plan replaces the predecessor plans (the "Prior Plans") that the Company assumed following its merger with Zafgen, Inc. ("Zafgen") in May 2020. Options outstanding under the Prior Plans will remain outstanding, unchanged, and subject to the terms of the Prior Plans and the respective award agreements, and no further awards will be made under the Prior Plans. However, if any award previously granted under the Prior Plans, expires, terminates, is canceled, or is forfeited for any reason after the approval of the 2020 Plan, the shares subject to that award will be added to the 2020 Plan share pool so that they can be utilized for new grants under the 2020 Plan.

The 2020 Plan provides for the grant of incentive stock options (“ISOs”), nonstatutory stock options (“NSOs”), stock appreciation rights, restricted stock awards, restricted stock unit awards, and cash or other stock-based awards. ISOs may be granted only to the Company’s employees, including the Company’s officers, and the employees of the Company’s affiliates. All other awards may be granted to the Company’s employees, including the Company’s officers, the Company’s non-employee directors and consultants, and the employees and consultants of the Company’s affiliates.

The maximum number of shares that may be issued in respect of any awards under the 2020 Plan is the sum of: (i) 1,700,000 shares plus (ii) an annual increase on January 1, 2021 and each anniversary of such date thereafter through January 1, 2030, equal to the lesser of (A) 4% of the shares issued and outstanding on the last day of the immediately preceding fiscal year, and (B) such smaller number of shares as determined by the Board (collectively, the “Plan Limit”). The maximum aggregate number of shares that may be issued under the 2020 Plan is 8,000,000 over the ten-year term of the 2020 Plan. In 2022 and 2021, respectively, options to purchase 450 and 56,966 shares issued under the Prior Plans were cancelled and became available for grant under the 2020 Plan.

As permitted by the 2020 Plan, the Company added 708,418 shares available for grant under the 2020 Plan on January 1, 2022. As of March 31, 2022, 1,114,743 shares of common stock were available for grant under the 2020 Plan.

Stock Valuation

The following table presents, on a weighted average basis, the assumptions used in the Black-Scholes option-pricing model to determine the grant-date fair value of stock options granted to employees:

	March 31,	December 31,
	2022	2021
Risk-free interest rate	1.75%	0.89%
Expected term (in years)	6.25	6.19
Expected volatility	90%	91%
Dividend yield	0.00%	0.00%

Stock Options

The following table summarizes the Company’s stock option activity for the three months ended March 31, 2022 (amounts in millions, except for share and per share data):

				Weighted		Weighted Average		Aggregate
				Average		Remaining		Intrinsic
	Number of			Exercise		Contractual		Value (a)
	Shares			Price		Term (in years)		(in millions)
Outstanding as of December 31, 2021		2,523,305		$	1.88		7.6
Granted		600,950			8.81
Forfeited/Expired		(45,744	)		27.97
Outstanding as of March 31, 2022		3,078,511		$	16.78		7.9	$	—
Exercisable as of March 31, 2022		1,195,114		$	24.53		6.3	$	—
Vested and expected to vest as of March 31, 2022		3,078,511		$	16.78		7.9	$	—

13

(a)The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying options and the fair value of the common stock for the options that were in the money at March 31, 2022.

2022 Option Grants

During the three months ended March 31, 2022, the Company granted options to purchase 600,950 shares of common stock to employees of the Company under the 2020 Plan. The options have an exercise price equal to the closing stock price as of the grant date. These options vest over four years with 25% vesting on the first anniversary of the grant and the remainder vesting in equal monthly installments thereafter. The weighted-average grant date fair value of options granted during three months ended March 31, 2022 was $6.61.

In May 2022, the Company granted options to purchase 251,500 shares of common stock to employees and directors of the Company under the 2020 Plan. The options have an exercise price equal to the closing stock price as of the grant date. Of the 251,500 options granted in May 2022, 210,000 were granted to employees and vest over four years with 25% vesting on the first anniversary of the grant and the remainder vesting in equal monthly installments thereafter. The remaining 41,500 options were annual grants to the Company's directors and vest one year from the grant date.

Stock-Based Compensation

Stock-based compensation expense was classified in the condensed consolidated statements of operations as follows:

	Three Months Ended March 31,
	2022		2021
Research and development	$	655	$	438
General and administrative		980		742
	$	1,635	$	1,180

As of March 31, 2022, total unrecognized compensation expense related to unvested stock options and restricted stock units was $16.9 million, which is expected to be recognized over a weighted average period of 2.68 years.

8.Commitments and Contingencies

Intellectual Property Licenses

The Company is party to an exclusive License Agreement (the “WFUHS License”), dated November 30, 2016 with Wake Forest University Health Sciences (“WFUHS”) and an exclusive License Agreement (the “IU License”), dated November 30, 2016, as amended, with Indiana University (“IU”). Such agreements provide for a transferable, worldwide license to certain patent rights regarding technology used by the Company with respect to the development of CTI-1601.

In partial consideration for the right and license granted under these agreements, the Company will pay each of WFUHS and IU a royalty of a low single digit percentage of net sales of licensed products depending on whether there is a valid patent covering such products. As additional consideration for these agreements, the Company is obligated to pay each of WFUHS and IU certain milestone payments of up to $2.6 million in the aggregate upon the achievement of certain developmental milestones, commencing on the enrollment of the first patient in a Phase 1 clinical trial. The Company will also pay each of WFUHS and IU sublicensing fees ranging from a high-single digit to a low double-digit percentage of sublicense consideration depending on the Company’s achievement of certain regulatory milestones as of the time of receipt of the sublicense consideration. The Company is also obligated to reimburse WFUHS and IU for patent-related expenses. In the event that the Company disputes the validity of any of the licensed patents, the royalty rate would be tripled during such dispute. The Company is also obligated to pay to IU a minimum annual royalty of less than $0.1 million per annum starting in the 2020 calendar year for the term of the agreement.

In the event that the Company is required to pay IU consideration, then the Company may deduct 20% of such IU consideration on a dollar-for-dollar basis from the consideration due to WFUHS. In the event that the Company is required to pay WFUHS consideration, then the Company may deduct 60% of such WFUHS consideration on a dollar-for-dollar basis from the consideration due to IU.

During the three months ended March 31, 2022, no milestones were achieved and no milestone expense was recognized. Both agreements continue from their effective date through the last to expire of the licensed patents unless earlier terminated by either party in accordance with their terms.

Leases

On August 8, 2019, the Company entered into an operating lease for office space in Bala Cynwyd, Pennsylvania, effective as of December 15, 2019, for a period of three years and six months with an option to extend the lease for three additional years. Due to required tenant improvements to be completed by the landlord, the Company did not take immediate possession of the leased property and the lease term commenced on February 15, 2020.

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 is required to maintain a letter of credit, which upon signing was $1.3 million and is classified as restricted cash within the condensed 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 and determined there was no impairment.

15

The Sublease provides 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).

On November 5, 2018, the Company entered into an operating lease for office and lab space in Philadelphia, Pennsylvania, effective as of January 1, 2019, and expiring on December 31, 2020 with an option to extend the lease for two additional years. On August 4, 2020, the Company executed the first option to extend the lease for an additional year, expiring on December 31, 2021. On August 9, 2021, the Company executed the remaining option to extend the lease for an additional year, expiring on December 31, 2022. The Company has determined this lease extension qualifies as a short-term lease and have applied the accounting policy election to not record the related right-of-use asset and lease liabilities.

Expense arising from operating leases was $0.1 million during the three months ended March 31, 2022 and 2021, respectively. For operating leases, the weighted-average remaining lease term for leases at March 31, 2022 and December 31, 2021 was 7.4 and 7.6 years, respectively. For operating leases, the weighted average discount rate for leases at March 31, 2022 and December 31, 2021 was 11.0%. The Company has not entered into any financing leases.

Maturities of lease liabilities due under these lease agreements as of March 31, 2022 are as follows:

	Operating
(in thousands)	Leases
Nine months ending December 31, 2022	$	899
Year ended December 31, 2023		1,146
Year ended December 31, 2024		1,065
Year ended December 31, 2025		1,083
Year ended December 31, 2026		1,101
Thereafter		3,213
Total lease payments		8,507
Less: imputed interest		(2,646	)
Present value of lease liabilities	$	5,861

Legal Proceedings

The Company is not currently a party to any litigation, nor is management aware of any pending or threatened litigation against the Company, that it believes would materially affect the Company's business, operating results, financial condition or cash flows.

9.Related Party Transactions

In November 2016, the Company entered into a consulting agreement with Mark Payne, M.D (the “Consulting Engagement”). Dr. Payne was a director of Chondrial at that time, a full-time employee of IU and one of the inventors of the licensed IU intellectual property, and as such is entitled to a certain share of the revenues received by IU under the IU License. Pursuant to the terms of his consulting agreement the Company agreed to pay Dr. Payne $0.1 million per year over the term of the agreement and granted Dr. Payne 123,853 restricted Common Units in Holdings. On November 30, 2016, 30% immediately vested and was associated with Chondrial Therapeutics IP, LLC (“IP LLC”) becoming a subsidiary of Holdings, which was subsequently contributed to the Company on December 31, 2018. The remaining 70% vested ratably over 48 months beginning on December 1, 2016 and were fully vested as of December 31, 2020. The consulting agreement has a four-year term, subject to earlier termination. On November 30, 2020, The Company entered into a 1-month extension of the Consulting Engagement, expiring on December 31, 2020 and on January 1, 2021, the Company entered into a new consulting agreement with Dr. Payne which extended the term of the Consulting Engagement for a four-year term beginning on January 1, 2021. During the three months ended March 31, 2022 and 2021 the Company recognized less than $0.1 million related to this consulting agreement, recorded as research and development expense in the Condensed Consolidated Statements of Operations.

During 2021, the Company purchased a piece of laboratory equipment and lab supplies for a cumulative $0.1 million from a supplier of which one of the Company's directors is also a current director.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our condensed consolidated financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q (“Quarterly Report”), and the audited consolidated financial statements and notes thereto and management’s discussion and analysis of financial condition and results of operations for the year ended December 31, 2021 included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on March 25, 2022. Some of the information contained in this discussion and analysis or set forth elsewhere in this Quarterly Report, including information with respect to our plans and strategy for our business, includes forward-looking statements that involve risks, uncertainties, and assumptions. These statements are based on our beliefs and expectations about future outcomes and are subject to risks and uncertainties that could cause our actual results to differ materially from anticipated results. We undertake no obligation to publicly update these forward-looking statements, whether as a result of new information, future events or otherwise. You should read the “Risk Factors” section included in our Annual Report on Form 10-K filed with the SEC on March 25, 2022, in addition to the "Risk Factors" and “Forward-Looking Statements” sections of this Quarterly Report on Form 10-Q for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

Overview

We are a clinical-stage biotechnology company focused on developing treatments for patients suffering from complex rare diseases using our novel cell penetrating peptide technology platform. Our lead product candidate, 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 enough FXN due to a genetic abnormality. There is currently no effective therapy for FA.

We have completed two Phase 1 clinical trials in patients with FA. We have received an orphan drug designation, fast track designation and rare pediatric disease designation, from the U.S. Food and Drug Administration (the "FDA") for CTI‑1601. In addition, we received orphan drug designation for CTI-1601 from the European Commission and a Priority Medicines ("PRIME") designation from the European Medicines Agency ("EMA"). The receipt of such designations or positive opinions may not result in a faster development process, review or approval compared to products considered for approval under conventional FDA or EMA procedures and does not assure ultimate approval by the FDA or EMA.

Our cell penetrating peptide technology platform, which enables a therapeutic molecule to cross a cell membrane in order to reach intracellular targets, has the potential to enable the treatment of other rare and orphan diseases. We intend to use our proprietary platform to target additional orphan indications characterized by deficiencies in or alterations of intracellular content or activity.

Since our inception, we have devoted substantially all of our resources to developing CTI-1601, building our intellectual property portfolio, developing third-party manufacturing capabilities, business planning, raising capital, and providing general and administrative support for such operations.

CTI-1601 Program Update

On May 20, 2021 we announced that we had received an EMA PRIME designation for CTI-1601 in FA. Through PRIME, the EMA offers early and proactive support to medicine developers to optimize the generation of robust data on a medicine’s benefits and risks and enable accelerated assessment of medicines applications so that these medicines can reach patients earlier. The PRIME designation was based on both pre-clinical data as well as tolerability data from the CTI-1601 Phase 1 program in patients with FA.

In May 2021, we reported positive topline data from our 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 demonstrate proof-of-concept by showing that daily subcutaneous injections of CTI-1601 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). FXN levels achieved in peripheral tissues (buccal cells) following daily 50 mg and 100 mg subcutaneous injections of CTI-1601 were at or in excess of FXN levels that

18

would be expected in phenotypically normal heterozygous carriers. There were no serious adverse events ("SAEs") associated with either the MAD or SAD trials.

In May 2021, the FDA placed a clinical hold on our CTI-1601 clinical program after we notified the agency of mortalities at the highest dose levels of the 26-week non-human primate toxicology study that was designed to support extended dosing of patients with CTI-1601. At the time the hold was placed, we had no interventional clinical trials with patients enrolling or enrolled. In February 2022, in response to the complete response we submitted to the FDA, the Agency stated that it was maintaining the clinical hold and that additional data are needed to resolve the clinical hold. We subsequently submitted a request for an FDA Type C meeting. This request was granted and is scheduled for early in the third quarter of 2022. Throughout the course of the interactions associated with the Type C meeting, we intend to work with the Agency to enable resolution of the clinical hold and to agree on the study design and timing of the next proposed clinical trial. We do not know when, or if the clinical hold will be lifted.

Financing Activities

We have funded our operating and capital requirements to date primarily with proceeds from sales of common stock and prefunded warrants for the purchase of common stock and, prior to our May 2020 merger with Zafgen, with capital contributions from Chondrial Holdings, LLC ("Holdings").

In August 2020, we entered into an Equity Distribution Agreement ("the ATM Agreement") with an investment bank in connection with the establishment of an “at-the-market” offering program under which we could sell up to an aggregate of $50,000,000 of shares of our common stock from time to time through this investment bank as sales agent.

In July 2021, we sold 2,342,720 shares pursuant to the ATM Agreement for net proceeds of $19.9 million, after issuance costs. As of May 10, 2022, $29.2 million of additional shares of common stock remained available for sale by us under the ATM Agreement.

In March 2020, the World Health Organization ("WHO") declared the outbreak of COVID-19, a novel strain of Coronavirus, a global pandemic. The pandemic resulted in the temporary stoppage of our CTI-1601 Phase 1 clinical trials in patients with Friedreich’s ataxia in March 2020. In July 2020, we resumed these clinical trials, and have since completed both the SAD and MAD clinical trials. Since being discovered, new variants of COVID-19 have emerged, including the Omicron variant, the Alpha variant, the Beta variant, the Gamma variant, and the Delta variant.

Vaccines manufactured by Moderna, Pfizer and Johnson & Johnson were introduced late in the fourth quarter of 2020 and became widely available by the end of the first quarter of 2021. While the vaccines have proven effective in reducing the severity and mortality of COVID-19, including the variants that have evolved to date, the overall vaccination rate in the United States has not reached the level required for herd immunity in some states, particularly in some regions of the country. Further, additional doses of vaccines have been and may be required in the future, and individuals may refuse or fail to receive one or more of such doses. The incidence of variants of COVID-19 has been increasing, particularly among unvaccinated individuals, and the Omicron variant has proven to be more easily spread than earlier variants.

The low vaccination rate, the spread of the variants and the evolution of additional mutations against which the current vaccines may prove ineffective could again result in major disruptions to businesses and markets worldwide. Furthermore, the incidence of "breakthrough" infections even among vaccinated individuals have been increasing, resulting in the need for booster doses which could make COVID-19 a long-term infectious disease concern. Our business, results of operations, financial condition and cash flows could be materially and adversely affected. Specifically, we could experience additional delays in future clinical trial timelines as a result of additional travel and hospital restrictions related to the COVID-19 pandemic and the efforts to mitigate it which may be imposed or could experience supply shortages or manufacturer shutdowns impacting the manufacture of drug

19

substance or drug product, which could also impact clinical trial timelines. The financial statements do not reflect any adjustments as a result of the pandemic.

Financial Operations Overview

Revenue

To date, we have not generated any revenue from product sales, and do not expect to generate any revenue from the sale of products in the foreseeable future. If our development efforts result in clinical success and regulatory approval or collaboration agreements with third parties for our product candidates, we may generate revenue from those product candidates or collaborations.

Operating Expenses

The majority of our operating expenses since inception have consisted primarily of research and development activities, and general and administrative costs.

Research and Development Expenses

Research and development expenses, which consist primarily of costs associated with our product research and development efforts, are expensed as incurred. Research and development expenses consist primarily of:

•third-party contract costs relating to research, formulation, manufacturing, non-clinical studies, and clinical trial activities;

•employee related costs, including salaries, benefits and stock-based compensation expenses for employees engaged in scientific research and development functions;

•external costs of outside consultants and vendors;

•payments made under our third-party licensing agreements;

•sponsored research agreements;

•laboratory consumables; and

•allocated facility-related costs.

Costs for certain activities, such as manufacturing, non-clinical studies and clinical trials are generally recognized based on the evaluation of the progress of completion of specific tasks using information and data provided by our vendors and collaborators. Research and development activities are central to our business. We expect to increase our investment in research and development in order to advance CTI-1601 through additional clinical trials. As a result, we expect that our research and development expenses will increase in the foreseeable future as we pursue clinical development of CTI-1601 and/or any other product candidates we develop.

At this time, we cannot reasonably estimate or know the nature, timing and estimated costs of the efforts that will be necessary to complete the clinical and commercial development of CTI-1601 or any other product candidates we develop. We are also unable to predict when, if ever, material net cash inflows will commence from sales of our product candidates. The duration, costs, and timing of clinical trials and development of CTI-1601 or any other product candidates we develop will depend on a variety of factors, including:

•the scope, rate of progress and expense of clinical trials and other research and development activities, including the ongoing impact of COVID-19 on these activities;

•clinical trial results;

•uncertainties in clinical trial enrollment rate or design;

•significant and changing government regulation;

•the timing and receipt of any regulatory approvals;

•the influence of the FDA’s or other regulatory authority’s on our clinical trial design and timing;

20

•establishing manufacturing capabilities or making arrangements with third-party manufacturers and risk involved with development of manufacturing processes, FDA pre-approval inspection practices and successful completion of manufacturing batches for clinical development and other regulatory purposes;

•the impact of the on-going COVID-19 pandemic including the mutations of the original virus that may prove more contagious and deadly;

•our ability to obtain and maintain patent and trade secret protection and regulatory exclusivity for our product candidates; and

•our ability to recruit and retain key research and development personnel.

A change in the outcome of any of these variables with respect to the development of a product candidate could significantly change the costs, timing and viability associated with the development of that product candidate. For example, if the FDA or another regulatory authority were to require us to conduct additional non-clinical or clinical trials beyond those that we currently anticipate will be required for the completion of clinical development of a product candidate, or if we experience significant delays in enrollment in any of our clinical trials, we could be required to expend significant additional financial resources and time on the completion of clinical development.

General and Administrative Expenses

General and administrative expenses consist primarily of personnel costs, consisting of salaries, related benefits and stock-based compensation, costs related to our executive, finance, information technology, and costs related to other administrative functions. General and administrative expenses also include insurance expenses and professional fees for auditing, tax, and legal services, including legal expenses to pursue patent protection for our intellectual property. We expect that our general and administrative expenses will increase in the foreseeable future as we hire additional employees to implement, improve and scale our operational, financial, commercial and management systems.

Critical Accounting Policies and Significant Judgments and Estimates

Our condensed consolidated financial statements are prepared in accordance with GAAP. The preparation of our condensed consolidated financial statements and related disclosures requires us to make estimates and assumptions that affect the reported amount of assets, liabilities, costs and expenses, and related disclosures. We believe that the estimates and assumptions involved in the accounting policies described below may have the greatest potential impact on our condensed consolidated financial statements and, therefore, consider these to be our critical accounting policies. We evaluate these estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions and conditions.

Research and Development Expenses

As part of the process of preparing our condensed consolidated financial statements, we are required to estimate our accrued research and development expenses and evaluate payments made to vendors in advance of actual work activities being performed. 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. The majority of our service providers invoice us in arrears for services performed, on a pre-determined schedule or when contractual milestones are met. We make estimates of our accrued expenses as of each balance sheet date in our condensed consolidated financial statements based on facts and circumstances known to us at that time. Examples of estimated accrued research and development expenses include fees paid to:

•CROs, in connection with clinical trials;

•vendors in connection with non-clinical development activities;

•contract manufacturing organizations in connection with the production of non-clinical and clinical trial materials; and

•vendors related to product candidate manufacturing, development, and distribution of clinical supplies.

21

We base our expenses related to clinical trials on our estimates of the services received and efforts expended pursuant to contracts with multiple CROs or CMOs that conduct and manage clinical trials or manufacture clinical trial material on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the clinical expense, non-clinical expense, or manufacturing activities. Payments under some of these contracts depend on factors such as the completion of clinical trial milestones. In accruing service fees, we estimate the time period over which services will be performed, enrollment of patients, number of sites activated and the level of effort to be expended in each period. In accruing CMO costs, we estimate the time period that manufacturing will be completed, the achievement of milestones and the percentage of completion of each specific CMO agreement. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or prepaid accordingly. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may result in us recognizing adjustments in future periods as additional information becomes available.

Stock-Based Compensation

We measure all stock-based awards granted to employees, non-employee consultants 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 generally the vesting period of the respective award. Typically, we issue awards with only service-based vesting conditions and record the expense for these awards using the straight-line method. We account for forfeitures as they occur.

We classify stock-based compensation expense in our condensed 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, we were a private company and lacked company-specific historical and implied volatility information for our common stock. Therefore, we estimate our expected common stock price volatility based on the historical volatility of publicly traded peer companies and expect to continue to do so until we have adequate historical data regarding the volatility of our own traded stock price. The expected term of our stock options have 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. Expected dividend yield considers the fact that we have never paid cash dividends on common stock and do not expect to pay any cash dividends in the foreseeable future.

Results of Operations

Comparison of three months ended March 31, 2022 and 2021

The following table summarizes our results of operations for the three months ended March 31, 2022 and 2021:

Research and development expenses

Research and development expenses for the three months ended March 31, 2022 decreased $3.2 million compared to the three months ended March 31, 2021. The decrease in research and development expenses as

22

compared to the prior year period was primarily driven by lower clinical supply manufacturing costs of $2.2 million and a decrease of $1.9 million in clinical trial costs, partially offset by an increase of $0.3 million in personnel related costs due to headcount additions in our research and development functions, higher non-clinical costs of $0.2 million, an increase of $0.2 million in professional fees primarily related to consulting services and an increase of $0.2 million in stock-based compensation expense associated with stock option grants made in 2021 and 2022.

General and administrative expenses

General and administrative expenses for the three months ended March 31, 2022 decreased $0.1 million compared to the three months ended March 31, 2021. The decrease in general and administrative expenses as compared to the prior year period was primarily driven by a decrease of $0.3 million in professional fees primarily associated with reduced recruiting and consulting services performed in the three months ended March 31, 2022 compared to the three months ended March 31, 2021, partially offset by an increase of $0.2 million in stock-based compensation expense associated with stock option grants made in 2021 and 2022 and an increase of $0.1 million in personnel related costs due to salary adjustments made in the three months ended March 31, 2022.

Liquidity and Capital Resources

Since our inception, we have not generated any revenue from any sources, including from product sales, and have incurred significant operating losses and negative cash flows from our operations. We have devoted substantially all of our resources to developing CTI-1601, building our intellectual property portfolio, developing third-party manufacturing capabilities, business planning, capital raising, and providing general and administrative support for such operations.

Cash Flows

The following table summarizes our sources and uses of cash for each of the periods presented below:

	Three Months Ended March 31,
	2022			2021
	(in thousands)
Net cash used in operating activities	$	(7,533	)	$	(11,206	)
Net cash provided by investing activities		—			5,251
Net cash provided by financing activities		—			—
Net increase in cash, cash equivalents and restricted cash	$	(7,533	)	$	(5,955	)

Net cash used in operating activities

During the three months ended March 31, 2022, operating activities used $7.5 million of cash, resulting from our net loss of $8.9 million, adjusted for noncash expenses of $1.7 million and changes in our operating assets and liabilities of $0.3 million. Our net loss was primarily attributed to research and development activities related to our CTI-1601 program and our general and administrative expenses as described above. Noncash expenses primarily include stock-based compensation expense. The change in operating assets and liabilities was primarily due to a decrease in accrued expenses and offset by an increase in accounts payable and prepaid expenses.

During the three months ended March 31, 2021, operating activities used $11.2 million of cash, resulting from our net loss of $12.1 million, adjusted for noncash expenses of $1.2 million and changes in our operating assets and liabilities of $0.4 million. Our net loss was primarily attributed to research and development activities related to our CTI-1601 program and our general and administrative expenses as described above. Noncash expenses primarily include stock-based compensation expense. The change in operating assets and liabilities was primarily due to a decrease in accrued expenses and offset by an increase in accounts payable and prepaid expenses due to the growth in our operating activities.

Net cash provided by investing activities

During the three months ended March 31, 2022, there were no investing activities.

23

During the three months ended March 31, 2021, investing activities provided $5.3 million of cash, resulting from a $7.0 million increase from maturities of marketable debt securities, which was partially offset by $1.7 million in purchases of new marketable debt securities.

Net cash provided by financing activities

During the three months ended March 31, 2022 and 2021 there were no financing activities.

24

Operating Capital Requirements

We have not yet commercialized any products and do not expect to generate revenue from the commercial sale of any products for several years, if at all.

We have to date incurred net losses. We incurred net losses of approximately $8.9 million and $12.1 million for the three months ended March 31, 2022 and 2021, respectively. As of March 31, 2022, we had an accumulated deficit of $125.2 million and cash and cash equivalents of $62.6 million, excluding restricted cash of $1.3 million.

Losses have resulted principally from costs incurred in connection with research and development activities, and general and administrative costs associated with the development of CTI-1601 and our operations. We expect to incur significant expenses and operating losses for the foreseeable future as we expect to continue to incur expenses in connection with our ongoing activities, if and as we:

•continue to advance the development of CTI-1601 through additional clinical trials;

•seek to identify and advance development of additional product candidates into clinical development and identify additional indications for our product candidates;

•seek to obtain regulatory approvals for our product candidates;

•identify, acquire or in-license other product candidates and technologies;

•maintain, leverage and expand our intellectual property portfolio; and

•expand our operational, financial, commercial and management systems and personnel, including personnel to support our clinical development and future commercialization efforts and our operations as a public company.

We believe that based on our current operating plan our cash and cash equivalents will be able fund operating expenses and capital expenditure requirements for at least the next twelve months. If we encounter unexpected delays in our clinical trials or if there are other unanticipated changes to our operating plan from our current assumptions that negatively impact our operations, we may reduce expenditures in order to further extend our existing cash resources. Until we can generate substantial revenue, if ever, we expect to seek additional funding through a combination of public or private equity offerings, debt financings, collaborations and licensing arrangements or other sources. The incurrence of indebtedness would result in increased fixed payment obligations and we may be required to agree to certain restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. Any additional fundraising efforts may divert our management from their day-to-day activities, which may adversely affect our ability to develop and commercialize our product candidates.

There can be no assurance that we will be able to raise sufficient additional capital on acceptable terms or at all. If such additional financing is not available on satisfactory terms, or is not available in sufficient amounts, or we do not have sufficient authorized shares, we may be required to delay, limit, or eliminate the development of business opportunities and our ability to achieve our business objectives, our competitiveness, and our business, financial condition, and results of operations will be materially adversely affected. We could also be required to seek funds through arrangements with collaborative partners or otherwise at an earlier stage than otherwise would be desirable and we may be required to relinquish rights to some of our technologies or product candidates or otherwise agree to terms unfavorable to us, any of which may have a material adverse effect on our business, operating results and prospects. In addition, geopolitical unrest including the potential impact of the Russian invasion of Ukraine and the possibility that the conflict could expand beyond eastern Europe, the impact of the COVID-19 pandemic and/or other health crises on the global financial markets may reduce our ability to access capital, which could negatively affect our liquidity and ability to continue as a going concern.

25

If we are unable to obtain funding when needed and/or on acceptable terms, we may be required to significantly curtail, delay or discontinue one or more of our research and development programs, the manufacture of clinical and commercial supplies, product portfolio expansion or pre commercialization efforts, which could adversely affect our business prospects, or we may be unable to continue operations. Certain restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. Any additional fundraising efforts may divert our management from their day-to-day activities, which may adversely affect our ability to develop and commercialize our product candidates.

Off-Balance Sheet Arrangements

During the periods presented we did not have, and we currently do not have, any off-balance sheet arrangements, as defined under applicable SEC rules, such as relationships with unconsolidated entities or financial partnerships, which are often referred to as structured finance or special purpose entities, established for the purpose of facilitating financing transactions that are not required to be reflected on our balance sheets.

Recently Issued Accounting Pronouncements

Item 3. Quantitative and Qualitative Disclosures about Market Risk

We are a "smaller reporting company" as defined by Rule 12b-2 of the Securities Exchange Act of 1934, as amended (the "Exchange Act") and are not required to provide the information under this item.

Item 4. Controls and Procedures

We maintain “disclosure controls and procedures,” as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, that are designed to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and our Chief Financial Officer, to allow timely decisions regarding required disclosure.

The design of any disclosure controls and procedures also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

With respect to the quarter ended March 31, 2022, under the supervision and with the participation of our management, we conducted an evaluation of the effectiveness of the design and operations of our disclosure controls and procedures. Based upon this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures are effective.

Management does not expect that our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control systems are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in a cost-effective control system, no evaluation of internal control over financial reporting can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been or will be detected.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the fiscal quarter ended March 31, 2022 which have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

27

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, we are subject to claims in legal proceedings arising in the normal course of business. To our knowledge, during the three months ended March 31, 2022, there were no, and as of the date of this Quarterly Report, there are no, threatened or pending legal actions that could reasonably be expected to have a material adverse effect on our business, financial condition, results of operations or cash flows.

Item 1A. Risk Factors

You should carefully consider the risk factors described in our 2021 Annual Report under the caption “Item 1A. Risk Factors.” The risks described in our Annual Report are not the only risks facing our company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or future results.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

None.

Item 3. Defaults Upon Senior Securities

None.

Item 4. Mine Safety Disclosures

Not applicable.

Item 5. Other Information

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization, Nature of the Business, COVID-19, Clinical Hold and Basis of Presentation

1.Organization, Clinical Development, Nature of the Business, COVID-19, Clinical Hold 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, 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. Friedreich’s ataxia is a rare, progressive and fatal disease in which patients are unable to produce sufficient FXN due to a genetic abnormality.

In May 2021, Larimar reported positive topline data from its Phase 1 Friedreich’s ataxia, ("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 demonstrate proof-of-concept by showing that daily subcutaneous injections of CTI-1601 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). FXN levels achieved in peripheral tissues (buccal cells) following daily 50 mg and 100 mg subcutaneous injections of CTI-1601 were at or in excess of FXN levels that would be expected in phenotypically normal heterozygous carriers. There were no serious adverse events, ("SAEs"), associated with either the MAD or SAD trials.

In May 2021, the FDA placed a clinical hold on the Company's CTI-1601 clinical program after the Company notified the agency of mortalities at the highest dose levels of the 26-week non-human primate toxicology study that was designed to support extended dosing of patients with CTI-1601. At the time the hold was placed, Larimar had no interventional clinical trials with patients enrolling or enrolled. In February 2022, in response to the Company submitting a complete response to the FDA, the Agency stated that it was maintaining the clinical hold and that additional data are needed to resolve the clinical hold. Larimar subsequently submitted a request for an FDA Type C meeting. This meeting request has been granted and is scheduled for early in the third quarter of 2022. Throughout the course of the interactions associated with the Type C meeting, Larimar intends to work with the Agency to enable resolution of the clinical hold and to agree on the study design and timing of the next proposed clinical trial. Larimar does not know when, or if the clinical hold will be lifted.

The Company is subject to risks and uncertainties common to pre-commercial companies in the biotechnology industry, including, but not limited to, development 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. Drug candidates currently 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, and infrastructure and extensive compliance-reporting capabilities. Even if our drug development efforts are successful, it is uncertain when, if ever, we will realize significant revenue from product sales.

In March 2020, the World Health Organization ("WHO"), declared the outbreak of COVID-19, a novel strain of Coronavirus, a global pandemic. The pandemic resulted in the temporary stoppage of the Company’s CTI-1601 Phase 1 clinical trials in patients with Friedreich’s ataxia in March 2020. In July 2020, the Company resumed these clinical trials, and has since completed both of the Company's SAD and MAD clinical trials. Since being discovered, new variants of COVID-19 have emerged. In November 2021, the Omicron variant was identified in South Africa, and has been deemed a variant of concern by the WHO. In addition to the Omicron variant, the WHO has deemed four other variants to be variants of concern: the Alpha variant, the Beta variant, the Gamma variant, and the Delta variant. All of the aforementioned variants have at least one of the following characteristics resulting in the WHO deeming them variants of concern: an increase in transmissibility or detrimental change in COVID-19 epidemiology, an increase in virulence or change in clinical disease presentation, or a decrease in effectiveness of public health and social measures or available diagnostics, vaccines, or therapeutics.

Vaccines manufactured by Moderna, Pfizer and Johnson & Johnson were introduced late in the fourth quarter of 2020 and became widely available by the end of the first quarter of 2021. While the vaccines have proven effective in reducing the severity and mortality of COVID-19, including the variants that have evolved to date, the overall vaccination rate has not reached the level required for herd immunity in some areas of the country. Further, additional doses of vaccines have been and may continue to be required and individuals may refuse or fail to receive one or more such doses. The incidence of variants of COVID-19 has been increasing, particularly among unvaccinated individuals, and the Omicron variant has proven to be more easily spread than earlier variants.

The low vaccination rate, the spread of the variants and the evolution of additional mutations against which the current vaccines may prove ineffective could again result in major disruptions to businesses and markets worldwide. Furthermore, the incidence of "breakthrough" infections even among vaccinated individuals have been increasing, resulting in the need for booster doses which could make COVID-19 a long-term infectious disease concern. The Company’s business, results of operations, financial condition and cash flows could be materially and adversely affected. Specifically, the Company could experience additional delays in future clinical trial timelines as a result of additional travel and hospital restrictions related to the COVID-19 pandemic and the efforts to mitigate it which may be imposed or could experience supply shortages or manufacturer shutdowns impacting the manufacture of drug substance or drug product, which could also impact clinical trial timelines. The condensed consolidated financial statements do not reflect any adjustments as a result of the pandemic.

Basis of Presentation

The condensed consolidated financial statements include the accounts of Larimar and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated. The accompanying condensed consolidated financial statements have been prepared in conformity with GAAP.

Going Concern Assessment

The Company’s condensed 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 $8.9 million and $12.1 million for the three months ended March 31, 2022 and 2021, respectively. In addition, as of March 31, 2022, the Company had an accumulated deficit of $125.2 million. The Company expects to continue to generate operating losses for the foreseeable future. As of March 31, 2022, the Company had approximately $62.6 million of cash and cash equivalents available for use to fund its operations and capital requirements.

In August 2020, the Company entered into an Equity Distribution Agreement (the “ATM Agreement”) with an investment bank in connection with the establishment of an “at-the-market” offering program under which the Company could sell up to an aggregate of $50,000,000 of shares of its common stock from time to time through this investment bank as sales agent. In 2021, the Company sold 2,342,720 shares pursuant to the ATM Agreement for gross proceeds of $20.5 million. As of May 10, 2022, $29.2 million of additional shares of common stock remained available for sale by the Company under the ATM Agreement. See Note 7 for a further discussion of the ATM Agreement.

In accordance with Accounting Standards Update (“ASU”) No. 2014-15, 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 the consolidated financial statements are issued. As of the issuance date of these condensed consolidated financial statements, the Company expects its cash and cash equivalents will be sufficient to fund its forecasted operating expenses and capital expenditure requirements, for at least the next twelve months from the issuance of these financial statements. If the timing of our clinical assumptions were delayed or if there were other forecasted assumption changes that negatively impact our operating plan, the Company could reduce expenditures in order to further extend cash resources.

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, will need additional capital to fund its future operating and capital requirements. Management is currently evaluating different strategies to obtain the required funding for future operations. Until the Company can generate substantial revenue, if ever, the Company expects to seek additional funding through a combination of public or private equity offerings, debt financings, collaborations and licensing arrangements or other sources. The incurrence of indebtedness would result in increased fixed 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 and other operating restrictions that could adversely impact the Company's ability to conduct our 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 our product candidates.

There can be no assurance that the Company will be able to raise sufficient additional capital on acceptable terms or at all. If such additional financing is not available on satisfactory terms, or is not available in sufficient amounts, or 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 unrest including the potential impact of the Russian invasion of Ukraine, the possibility that the conflict could expand beyond eastern Europe, the impact of the COVID-19 pandemic and/or 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 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 or pre commercialization efforts, which could adversely affect its business prospects, or the Company may be unable to continue operations.

Summary of Significant Accounting Policies

2.Summary of Significant Accounting Policies

Unaudited Interim Financial Information

The condensed consolidated balance sheet as of December 31, 2021 was derived from the Company’s audited financial statements but does not include all disclosures required by GAAP. The accompanying unaudited condensed consolidated financial statements as of March 31, 2022 and for the three months ended March 31, 2022 and 2021, have been prepared by the Company, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”), for interim financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto for the year ended December 31, 2021 included in the Company’s Annual Report on Form 10-K filed on March 25, 2022.

In the opinion of management, all adjustments, consisting only of normal recurring adjustments necessary for a fair statement of the Company’s condensed consolidated financial position as of March 31, 2022 and condensed consolidated results of operations and cash flows for the three months ended March 31, 2022 and 2021 have been made. The results of operations for the three months ended March 31, 2022 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2022.

Use of Estimates

The preparation of 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. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, the accrual of research and development expense, 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.

Research and Development Costs

Costs associated with internal research and development and external research and development services, including drug development, 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 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 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, non-employee consultants 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 and market-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 condensed 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 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. Therefore, the Company estimates its expected common stock price volatility based on the historical volatility of publicly traded peer companies and expects to continue to do so until it has adequate historical data regarding the volatility of its own traded stock price. 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. 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.

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. 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. Basic and diluted weighted average shares of common stock outstanding for the three months ended March 31, 2022 and 2021 includes the weighted average effect of 628,403 prefunded warrants for the purchase of shares of common stock, for which the remaining unfunded exercise price is $0.01 per share.

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 shares assuming the dilutive effect of outstanding stock options and unvested restricted common shares, as determined using the treasury stock method. For periods in which the Company has reported net losses, 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 shares are not assumed to have been issued if their effect is antidilutive.

The Company excluded 3,078,511 and 2,397,152 common stock equivalents outstanding as of March 31, 2022 and 2021, respectively, from the computation of diluted net loss per share for the three months ended March 31, 2022 and 2021 because they had an anti-dilutive impact due to the net loss incurred for the periods presented.

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 condensed consolidated results of operations, cash flows or financial position.

Fair Value Disclosures [Abstract]

Fair Value Measurements and Marketable Debt Securities

3.Fair Value Measurements and Marketable Debt Securities

Fair Value Measurements

The Company’s assets and liabilities that are measured at fair value on a recurring basis as of March 31, 2022 and December 31, 2021 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 the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows:

Level – 1	Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.
Level – 2	Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.
Level – 3	Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

The Company’s financial instruments consist primarily of cash, cash equivalents, marketable debt securities, accounts payable and accrued liabilities. For accounts payable and accrued liabilities, the carrying amounts of these financial instruments as of March 31, 2022 and December 31, 2021 were considered representative of their fair values due to their short term to maturity.

The following tables summarize the Company’s cash equivalents as of March 31, 2022 and December 31, 2021:

As of March 31, 2022, the Company’s Certificate of Incorporation, as amended and restated, authorized the Company to issue up to 115,000,000 shares of $0.001 par value common stock, of which 17,710,450 shares were issued and outstanding, and up to 5,000,000 shares of $0.001 par value undesignated preferred stock, of which no shares were issued or outstanding. The voting, dividend, and liquidation rights of the holders of the Company’s common stock are subject to and qualified by the rights, powers, and preferences of the holders of the preferred stock. Each share of common stock entitles the holder to one vote on all matters submitted to a vote of the Company’s stockholders. Common stockholders are entitled to receive dividends, as may be declared by the board of directors of the Company (the “Board”), if any. No cash dividends have been declared or paid to date.

Equity Distribution Agreement

On August 14, 2020, the Company entered into the ATM Agreement with an investment bank in connection with the establishment of an “at-the-market” offering program under which the Company may sell up to an aggregate of $50,000,000 of shares of common stock (the “ATM Shares”) from time to time (the “Offering”).

Under the ATM Agreement, the Company sets the parameters for the sale of ATM Shares, including the number of ATM Shares to be issued, the time period during which sales are requested to be made, limitations on the number of ATM Shares that may be sold in any one trading day and any minimum price below which sales may not be made. Sales of the ATM Shares, if any, under the ATM Agreement may be made in transactions that are deemed to be “at-the-market offerings” as defined in Rule 415 under the Securities Act. The Company pays its investment bank a commission equal to 3.0% of the gross proceeds of any ATM Shares sold through its investment bank under the ATM Agreement and reimburses the investment bank for certain specified expenses. The ATM Agreement contains customary representations, warranties and agreements by the Company, indemnification obligations of the Company and its investment bank, other customary obligations of the parties and termination provisions. The Company has no obligation to sell any of the ATM Shares and may at any time suspend offers under the ATM Agreement.

In 2021, the Company sold 2,342,720 shares under the ATM Agreement for net proceeds of $19.9 million.

As of March 31, 2022, 2,354,244 shares of Common Stock have been sold under the ATM Agreement for net proceeds of $20.1 million. As of May 10, 2022, approximately $29.2 million shares of common stock still remained available for sale by the Company under the ATM Agreement.

2020 Equity Incentive Plan

The Board adopted the 2020 Equity Incentive Plan (the "2020 Plan") on July 16, 2020 and the stockholders of the Company approved the 2020 Plan on September 29, 2020. The 2020 Plan replaces the predecessor plans (the "Prior Plans") that the Company assumed following its merger with Zafgen, Inc. ("Zafgen") in May 2020. Options outstanding under the Prior Plans will remain outstanding, unchanged, and subject to the terms of the Prior Plans and the respective award agreements, and no further awards will be made under the Prior Plans. However, if any award previously granted under the Prior Plans, expires, terminates, is canceled, or is forfeited for any reason after the approval of the 2020 Plan, the shares subject to that award will be added to the 2020 Plan share pool so that they can be utilized for new grants under the 2020 Plan.

The 2020 Plan provides for the grant of incentive stock options (“ISOs”), nonstatutory stock options (“NSOs”), stock appreciation rights, restricted stock awards, restricted stock unit awards, and cash or other stock-based awards. ISOs may be granted only to the Company’s employees, including the Company’s officers, and the employees of the Company’s affiliates. All other awards may be granted to the Company’s employees, including the Company’s officers, the Company’s non-employee directors and consultants, and the employees and consultants of the Company’s affiliates.

The maximum number of shares that may be issued in respect of any awards under the 2020 Plan is the sum of: (i) 1,700,000 shares plus (ii) an annual increase on January 1, 2021 and each anniversary of such date thereafter through January 1, 2030, equal to the lesser of (A) 4% of the shares issued and outstanding on the last day of the immediately preceding fiscal year, and (B) such smaller number of shares as determined by the Board (collectively, the “Plan Limit”). The maximum aggregate number of shares that may be issued under the 2020 Plan is 8,000,000 over the ten-year term of the 2020 Plan. In 2022 and 2021, respectively, options to purchase 450 and 56,966 shares issued under the Prior Plans were cancelled and became available for grant under the 2020 Plan.

As permitted by the 2020 Plan, the Company added 708,418 shares available for grant under the 2020 Plan on January 1, 2022. As of March 31, 2022, 1,114,743 shares of common stock were available for grant under the 2020 Plan.

2022 Option Grants

During the three months ended March 31, 2022, the Company granted options to purchase 600,950 shares of common stock to employees of the Company under the 2020 Plan. The options have an exercise price equal to the closing stock price as of the grant date. These options vest over four years with 25% vesting on the first anniversary of the grant and the remainder vesting in equal monthly installments thereafter. The weighted-average grant date fair value of options granted during three months ended March 31, 2022 was $6.61.

In May 2022, the Company granted options to purchase 251,500 shares of common stock to employees and directors of the Company under the 2020 Plan. The options have an exercise price equal to the closing stock price as of the grant date. Of the 251,500 options granted in May 2022, 210,000 were granted to employees and vest over four years with 25% vesting on the first anniversary of the grant and the remainder vesting in equal monthly installments thereafter. The remaining 41,500 options were annual grants to the Company's directors and vest one year from the grant date.

Stock-Based Compensation

Stock-based compensation expense was classified in the condensed consolidated statements of operations as follows:

	Three Months Ended March 31,
	2022		2021
Research and development	$	655	$	438
General and administrative		980		742
	$	1,635	$	1,180

As of March 31, 2022, total unrecognized compensation expense related to unvested stock options and restricted stock units was $16.9 million, which is expected to be recognized over a weighted average period of 2.68 years.

8.Commitments and Contingencies

Intellectual Property Licenses

The Company is party to an exclusive License Agreement (the “WFUHS License”), dated November 30, 2016 with Wake Forest University Health Sciences (“WFUHS”) and an exclusive License Agreement (the “IU License”), dated November 30, 2016, as amended, with Indiana University (“IU”). Such agreements provide for a transferable, worldwide license to certain patent rights regarding technology used by the Company with respect to the development of CTI-1601.

In partial consideration for the right and license granted under these agreements, the Company will pay each of WFUHS and IU a royalty of a low single digit percentage of net sales of licensed products depending on whether there is a valid patent covering such products. As additional consideration for these agreements, the Company is obligated to pay each of WFUHS and IU certain milestone payments of up to $2.6 million in the aggregate upon the achievement of certain developmental milestones, commencing on the enrollment of the first patient in a Phase 1 clinical trial. The Company will also pay each of WFUHS and IU sublicensing fees ranging from a high-single digit to a low double-digit percentage of sublicense consideration depending on the Company’s achievement of certain regulatory milestones as of the time of receipt of the sublicense consideration. The Company is also obligated to reimburse WFUHS and IU for patent-related expenses. In the event that the Company disputes the validity of any of the licensed patents, the royalty rate would be tripled during such dispute. The Company is also obligated to pay to IU a minimum annual royalty of less than $0.1 million per annum starting in the 2020 calendar year for the term of the agreement.

In the event that the Company is required to pay IU consideration, then the Company may deduct 20% of such IU consideration on a dollar-for-dollar basis from the consideration due to WFUHS. In the event that the Company is required to pay WFUHS consideration, then the Company may deduct 60% of such WFUHS consideration on a dollar-for-dollar basis from the consideration due to IU.

During the three months ended March 31, 2022, no milestones were achieved and no milestone expense was recognized. Both agreements continue from their effective date through the last to expire of the licensed patents unless earlier terminated by either party in accordance with their terms.

Leases

On August 8, 2019, the Company entered into an operating lease for office space in Bala Cynwyd, Pennsylvania, effective as of December 15, 2019, for a period of three years and six months with an option to extend the lease for three additional years. Due to required tenant improvements to be completed by the landlord, the Company did not take immediate possession of the leased property and the lease term commenced on February 15, 2020.

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 is required to maintain a letter of credit, which upon signing was $1.3 million and is classified as restricted cash within the condensed 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 and determined there was no impairment.

The Sublease provides 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).

On November 5, 2018, the Company entered into an operating lease for office and lab space in Philadelphia, Pennsylvania, effective as of January 1, 2019, and expiring on December 31, 2020 with an option to extend the lease for two additional years. On August 4, 2020, the Company executed the first option to extend the lease for an additional year, expiring on December 31, 2021. On August 9, 2021, the Company executed the remaining option to extend the lease for an additional year, expiring on December 31, 2022. The Company has determined this lease extension qualifies as a short-term lease and have applied the accounting policy election to not record the related right-of-use asset and lease liabilities.

Expense arising from operating leases was $0.1 million during the three months ended March 31, 2022 and 2021, respectively. For operating leases, the weighted-average remaining lease term for leases at March 31, 2022 and December 31, 2021 was 7.4 and 7.6 years, respectively. For operating leases, the weighted average discount rate for leases at March 31, 2022 and December 31, 2021 was 11.0%. The Company has not entered into any financing leases.

Maturities of lease liabilities due under these lease agreements as of March 31, 2022 are as follows:

	Operating

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The condensed consolidated financial statements include the accounts of Larimar and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated. The accompanying condensed consolidated financial statements have been prepared in conformity with GAAP.

Unaudited Interim Financial Information

The condensed consolidated balance sheet as of December 31, 2021 was derived from the Company’s audited financial statements but does not include all disclosures required by GAAP. The accompanying unaudited condensed consolidated financial statements as of March 31, 2022 and for the three months ended March 31, 2022 and 2021, have been prepared by the Company, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”), for interim financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto for the year ended December 31, 2021 included in the Company’s Annual Report on Form 10-K filed on March 25, 2022.

In the opinion of management, all adjustments, consisting only of normal recurring adjustments necessary for a fair statement of the Company’s condensed consolidated financial position as of March 31, 2022 and condensed consolidated results of operations and cash flows for the three months ended March 31, 2022 and 2021 have been made. The results of operations for the three months ended March 31, 2022 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2022.

Going Concern Assessment

Going Concern Assessment

The Company’s condensed 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 $8.9 million and $12.1 million for the three months ended March 31, 2022 and 2021, respectively. In addition, as of March 31, 2022, the Company had an accumulated deficit of $125.2 million. The Company expects to continue to generate operating losses for the foreseeable future. As of March 31, 2022, the Company had approximately $62.6 million of cash and cash equivalents available for use to fund its operations and capital requirements.

In August 2020, the Company entered into an Equity Distribution Agreement (the “ATM Agreement”) with an investment bank in connection with the establishment of an “at-the-market” offering program under which the Company could sell up to an aggregate of $50,000,000 of shares of its common stock from time to time through this investment bank as sales agent. In 2021, the Company sold 2,342,720 shares pursuant to the ATM Agreement for gross proceeds of $20.5 million. As of May 10, 2022, $29.2 million of additional shares of common stock remained available for sale by the Company under the ATM Agreement. See Note 7 for a further discussion of the ATM Agreement.

In accordance with Accounting Standards Update (“ASU”) No. 2014-15, 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 the consolidated financial statements are issued. As of the issuance date of these condensed consolidated financial statements, the Company expects its cash and cash equivalents will be sufficient to fund its forecasted operating expenses and capital expenditure requirements, for at least the next twelve months from the issuance of these financial statements. If the timing of our clinical assumptions were delayed or if there were other forecasted assumption changes that negatively impact our operating plan, the Company could reduce expenditures in order to further extend cash resources.

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, will need additional capital to fund its future operating and capital requirements. Management is currently evaluating different strategies to obtain the required funding for future operations. Until the Company can generate substantial revenue, if ever, the Company expects to seek additional funding through a combination of public or private equity offerings, debt financings, collaborations and licensing arrangements or other sources. The incurrence of indebtedness would result in increased fixed 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 and other operating restrictions that could adversely impact the Company's ability to conduct our 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 our product candidates.

There can be no assurance that the Company will be able to raise sufficient additional capital on acceptable terms or at all. If such additional financing is not available on satisfactory terms, or is not available in sufficient amounts, or 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 unrest including the potential impact of the Russian invasion of Ukraine, the possibility that the conflict could expand beyond eastern Europe, the impact of the COVID-19 pandemic and/or 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 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 or pre commercialization efforts, which could adversely affect its business prospects, or the Company may be unable to continue operations.

Use of Estimates

Use of Estimates

The preparation of 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. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, the accrual of research and development expense, 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.

Research and Development Costs

Research and Development Costs

Costs associated with internal research and development and external research and development services, including drug development, 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 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 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

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

Stock-Based Compensation

The Company measures all stock-based awards granted to employees, non-employee consultants 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 and market-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 condensed 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 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. Therefore, the Company estimates its expected common stock price volatility based on the historical volatility of publicly traded peer companies and expects to continue to do so until it has adequate historical data regarding the volatility of its own traded stock price. 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. 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.

Net Loss Per Share

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. 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. Basic and diluted weighted average shares of common stock outstanding for the three months ended March 31, 2022 and 2021 includes the weighted average effect of 628,403 prefunded warrants for the purchase of shares of common stock, for which the remaining unfunded exercise price is $0.01 per share.

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 shares assuming the dilutive effect of outstanding stock options and unvested restricted common shares, as determined using the treasury stock method. For periods in which the Company has reported net losses, 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 shares are not assumed to have been issued if their effect is antidilutive.

The Company excluded 3,078,511 and 2,397,152 common stock equivalents outstanding as of March 31, 2022 and 2021, respectively, from the computation of diluted net loss per share for the three months ended March 31, 2022 and 2021 because they had an anti-dilutive impact due to the net loss incurred for the periods presented.

Recently Issued and Adopted Accounting Pronouncements

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 condensed consolidated results of operations, cash flows or financial position.
