NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. Nature of Business, Basis of Presentation and Liquidity

Nature of Business

Leap Therapeutics, Inc. was incorporated in the state of Delaware on January 3, 2011. During 2015, HealthCare Pharmaceuticals Pty Ltd. was formed and is a wholly owned subsidiary of the Company.

On December 10, 2015, the Company entered into a merger agreement with GITR Inc. (“GITR”), an entity under common control, whereby a wholly owned subsidiary was merged with GITR and the surviving name of the wholly owned subsidiary was GITR Inc.

On August 29, 2016, the Company entered into a merger agreement with Macrocure Ltd. (“Macrocure”), a publicly held, clinical stage biotechnology company based in Petach Tikva, Israel. In connection with the merger, the Company applied to be listed on the Nasdaq Global Market. Nasdaq approved the listing, and trading in the Company’s common stock commenced on January 24, 2017, under the trading symbol “LPTX.” On February 1, 2017, Macrocure’s name was changed to Leap Therapeutics Ltd. In 2020, Leap Therapeutics Ltd. was dissolved.

On December 15, 2021, Leap Securities Corp. was formed and is a wholly owned subsidiary of the Company.

On January 17, 2023, the Company entered into a merger agreement with Flame Biosciences, Inc., a privately held, biotechnology corporation (“Flame”), whereby Flame became a wholly owned subsidiary of the Company under the name Flame Biosciences LLC.

The Company is a biopharmaceutical company developing novel biomarker-targeted antibody therapies designed to treat patients with cancer by inhibiting fundamental tumor-promoting pathways, targeting cancer-specific cell surface molecules, and harnessing the immune system to attack cancer cells. The Company’s strategy is to identify, acquire, and develop molecules that translate into therapeutics that generate durable clinical benefit and enhanced patient outcomes. The Company’s lead clinical stage program is DKN-01, a monoclonal antibody that inhibits Dickkopf-related protein 1, or DKK1. The Company is currently studying DKN-01 in multiple ongoing clinical trials in patients with esophagogastric cancer, gynecologic cancers, or colorectal cancer. Its second clinical stage program is FL-301, a monoclonal antibody that targets cells that express Claudin18.2 on their cell surface. The Company also has two preclinical antibody programs, FL-302 and FL-501.

In January 2020, the Company entered into an Option and License Agreement with BeiGene, Ltd., or BeiGene, which granted BeiGene an option to obtain an exclusive license from the Company that would grant to BeiGene the right to develop and commercialize DKN-01 in Asia (excluding Japan), Australia, and New Zealand. In March 2023, BeiGene notified the Company that it did not intend to exercise its option, and the agreement is continuing as a clinical collaboration.

The Company intends to apply its experience identifying and developing products to build a pipeline of programs relating to the practice of cancer medicine.

Basis of Presentation

The December 31, 2023 year-end condensed consolidated balance sheet data in the accompanying interim condensed consolidated financial statements was derived from audited consolidated financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“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, 2023, included in the Company’s Annual Report on Form 10-K filed with the SEC on March 18, 2024.

The accompanying interim condensed consolidated financial statements are unaudited and have been prepared on the same basis as the audited consolidated financial statements as of and for the year ended December 31, 2023. In the opinion of management, the accompanying condensed consolidated financial statements contain all adjustments which are necessary for the fair presentation of the Company’s financial position as of June 30, 2024, statements of operations and statements of comprehensive loss for the three and six months ended June 30, 2024 and 2023 and statements of cash flows for the six months ended June 30, 2024 and 2023. Such adjustments are of a normal and recurring nature. The results of operations for the three and six months ended June 30, 2024 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2024.

Liquidity

Since inception, the Company has been engaged in organizational activities, including raising capital, and research and development activities. The Company does not yet have a product that has been approved by the FDA, has not generated any product sales revenues and has not yet achieved profitable operations, nor has it ever generated positive cash flows from operations. There is no assurance that profitable operations, if achieved, could be sustained on a continuing basis. Further, the Company’s future operations are dependent on the success of the Company’s efforts to raise additional capital, its research and commercialization efforts, regulatory approval, and, ultimately, the market acceptance of the Company’s products.

In accordance with Accounting Standards Codification (“ASC”) 205-40, Going Concern, the Company has evaluated whether there are 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 condensed consolidated financial statements are issued. As of June 30, 2024, the Company had cash and cash equivalents of $78,479. Additionally, the Company had an accumulated deficit of $433,764 at June 30, 2024, and during the six months ended June 30, 2024, the Company incurred a net loss attributable to common stockholders of $34,182. The Company expects to continue to generate operating losses for the foreseeable future. The Company believes that its cash and cash equivalents of $78,479 as of June 30, 2024 will be sufficient to fund its operating expenses for at least the next 12 months from issuance of these financial statements.

In addition, to support its future operations, the Company will likely seek additional funding through public or private equity financings or government programs and will seek funding or development program cost-sharing through collaboration agreements or licenses with larger pharmaceutical or biotechnology companies. If the Company does not obtain additional funding or development program cost-sharing, or exceeds its current spending forecasts or fails to receive the research and development tax incentive payment, the Company has the ability and would be forced to delay, reduce or eliminate certain clinical trials or research and development programs, reduce or eliminate discretionary operating expenses, and delay company and pipeline expansion, any of which could adversely affect its business prospects. The inability to obtain funding, as and when needed, could have a negative impact on the Company’s financial condition and ability to pursue its business strategies.

2. Summary of Significant Accounting Policies

Principles of Consolidation

The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions are eliminated upon consolidation.

Use of Estimates

The presentation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Research and development incentive income and receivable

The Company recognizes other income from Australian research and development incentives when there is reasonable assurance that the income will be received, the relevant expenditure has been incurred, and the consideration can be reliably measured. The research and development incentive is one of the key elements of the Australian government’s support for Australia’s innovation system and is supported by legislative law primarily in the form of the Australian Income Tax Assessment Act 1997, as long as eligibility criteria are met.

Management has assessed the Company’s research and development activities and expenditures to determine which activities and expenditures are likely to be eligible under the research and development incentive regime described above. At each period end, management estimates the refundable tax offset available to the Company based on available information at the time.

Under the program, a percentage of eligible research and development expenses incurred by the Company through its subsidiary in Australia are reimbursed. The percentage was 43.5% for the year ended December 31, 2023 and for the six months ended June 30, 2024.

The research and development incentive receivable represents an amount due in connection with the above program. The Company recorded a research and development incentive receivable of $1,259 and $771 as of June 30, 2024 and December 31, 2023, respectively, in the condensed consolidated balance sheets and other income from Australian research and development incentives of $253 and $298, respectively, for the three months ended June 30, 2024 and 2023 and $499 and $570 for the six months ended June 30, 2024 and 2023, respectively, in the condensed consolidated statements of operations related to refundable research and development incentive program payments in Australia.

The following table shows the change in the research and development incentive receivable from January 1, 2023 to June 30, 2024 (in thousands):

Foreign Currency Translation

The financial statements of the Company’s Australian subsidiary are measured using the local currency as the functional currency. The assets and liabilities of this subsidiary are translated into U.S. dollars at an exchange rate as of the consolidated balance sheet date. Equity is translated at historical exchange rates. Revenues and expenses are translated into U.S. dollars at average rates of exchange in effect during the period. The resulting cumulative translation adjustments have been recorded as a separate component of stockholders’ equity. Realized and unrealized foreign currency transaction gains and losses are included in the results of operations.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to credit risk consist principally of cash and cash equivalents. All cash and cash equivalents are held in United States or Australian financial institutions and money market funds. At times, the Company may maintain cash balances in excess of the federally insured amount of $250 per depositor, per insured bank, for each account ownership category. Although the Company currently believes that the financial institutions with whom it does business will be able to fulfill their commitments to the Company, there is no assurance that those institutions will be able to continue to do so. The Company has not experienced any credit losses associated with its balances in such accounts for the year ended December 31, 2023 or for the six months ended June 30, 2024.

Deposits

As of June 30, 2024 and December 31, 2023, there were $859 and $966, respectively, of deposits made by the Company with certain service providers that are to be applied to future payments due under the service agreements or returned to the Company if not utilized, which were recorded in the condensed consolidated balance sheets.

Warrants

The Company will recognize on a prospective basis the value of the effect of the down round feature in the warrants to purchase shares of common stock that were issued in a private placement in November 2017 (the “2017 Warrants”) and in the warrants that were issued in a private placement in March 2020 (the “March 2020 Coverage Warrants”) when it is triggered (i.e., when the exercise

price is adjusted downward). This value is measured as the difference between (1) the financial instrument’s fair value (without the down round feature) using the pre-trigger exercise price and (2) the financial instrument’s fair value (with the down round feature) using the reduced exercise price. The value of the effect of the down round feature will be treated as a dividend and a reduction to income available to common stockholders in the basic earnings per share (“EPS”) calculation. In connection with the private placement of common stock and prefunded warrants completed in April 2024 (the “April 2024 Private Placement”), when the 2017 Warrants were repriced from $10.55 to $2.82 as a result of a down round, the Company recorded a dividend of $234 during the three and six months ended June 30, 2024.

The Company initially classified the warrants that were exercisable for shares for Series X Non-Voting Convertible Preferred Stock (the “January 2023 Series X Preferred Stock Warrants”) as a liability on its condensed consolidated balance sheet on January 17, 2023 and subsequently remeasured the warrant liability to fair value at each reporting date until the conversion of Series X Non-Voting Convertible Preferred Stock (the “Series X Preferred Stock”) into common stock, which occurred on June 21, 2023. Changes in the fair value of the warrant liability were recognized as gains (losses) in the Company’s condensed consolidated statement of operations.

In June 2023, in connection with obtaining Stockholder Approval to convert shares of Series X Preferred Stock into shares of common stock (“Stockholder Approval”), the January 2023 Series X Preferred Stock Warrants were reclassified from liability to equity.

Fair Value of Financial Instruments

Certain assets and liabilities are carried at fair value under GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable:

A summary of the assets carried at fair value in accordance with the hierarchy defined above is as follows (in thousands):

Cash equivalents of $41,034 and $39,065 as of June 30, 2024 and December 31, 2023, respectively, consisted of overnight investments and money market funds which are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices in active markets.

The carrying values of the research and development incentive receivable, accounts payable and accrued liabilities approximate their fair value due to the short-term nature of these assets and liabilities.

Leases

The Company accounts for leases in accordance with Accounting Standards Codification, or ASC, Topic 842,Leases.

At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the unique facts and circumstances present. Most leases with a term greater than one year are recognized on the balance sheet as right-of-use assets, lease liabilities and, if applicable, long-term lease liabilities. The Company has elected not to recognize on the balance sheet leases with terms of one year or less. Operating lease liabilities and their corresponding right-of-use assets are recorded based on the present value of lease payments over the expected remaining lease term. The Company has determined that the rate implicit in the lease is not determinable and the Company does not have borrowings with similar terms and collateral. Therefore, the Company considered a variety of factors, including observable debt yields from comparable companies and the volatility in the debt market for securities with similar terms, in determining that 8% was reasonable to use as the incremental borrowing rate for purposes of the calculation of lease liabilities.

In accordance with the guidance in Topic 842, components of a lease should be split into three categories: lease components (e.g., land, building, etc.), non-lease components (e.g., common area maintenance, maintenance, consumables, etc.), and non-components (e.g., property taxes, insurance, etc.). Then the fixed and in-substance fixed contract consideration (including any related to non-components) must be allocated based on fair values to the lease components and non-lease components.

Although separation of lease and non-lease components is required, certain practical expedients are available. Entities may elect the practical expedient to not separate lease and non-lease components. Rather, they would account for each lease component and the related non-lease component together as a single component. The Company has elected to account for the lease and non-lease components of each of its operating leases as a single lease component and allocate all of the contract consideration to the lease component only. The lease component results in an operating right-of-use asset being recorded on the consolidated balance sheets and amortized such that lease expense is recorded on a straight line basis over the term of the lease.

Net Loss per Share

Basic net loss per share is computed using the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed using the weighted average number of common shares outstanding during the period and, if dilutive, the weighted average number of potential shares of common stock, including the assumed exercise of stock options and warrants.

Subsequent Events

The Company considers events or transactions that occur after the balance sheet date but prior to the issuance of the financial statements to provide additional evidence for certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated as required.

Recent Adopted Accounting Pronouncements

For a discussion of recent accounting pronouncements please refer to Note 2, “Summary of Significant Accounting Policies” in the Company’s previously filed Annual Report on Form 10-K for the year ended December 31, 2023.

3. Acquisition of Flame Biosciences

Merger

On January 17, 2023 (the “Effective Date”), Leap acquired 100% of the outstanding equity of Flame, in accordance with the terms of the Agreement and Plan of Merger, dated as of the Effective Date (the “Merger Agreement”), by and among Leap, Fire Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Leap (“First Merger Sub”), Flame Biosciences LLC, a Delaware limited liability company and wholly owned subsidiary of Leap (“Second Merger Sub”), Flame, and the Stockholder Representative named therein. Pursuant to the Merger Agreement, First Merger Sub merged with and into Flame, and Flame was the surviving corporation of such merger and became a wholly owned subsidiary of Leap (the “First Merger”). Immediately following the First Merger, Flame merged with and into Second Merger Sub, and Second Merger Sub was the surviving entity of such merger (together with the First Merger, the “Merger”).

Pursuant to the Merger, Leap agreed to issue to the stockholders of Flame (the “Flame Stockholders”)1,972,901 shares of common stock, and 136,248 shares of Series X Preferred Stock, which was a newly designated series of preferred stock that was intended to have economic rights equivalent to the common stock, but with limited voting rights, and issued to the warrant holders of Flame (the “Flame Warrant Holders”) the right to acquire 6,530 shares of common stock (the “January 2023 Common Stock Warrants”) and 443 shares of Series X Preferred Stock (the “January 2023 Series X Preferred Stock Warrants”). Each share of Series X Preferred Stock converted into 100 shares of common stock during the three months ended June 30, 2023, as a result of theone-for-ten reverse stock split approved by the stockholders and effected by the Board of Directors. Under the terms of the Merger Agreement, Leap held back approximately 15,604 Series X Preferred shares (the “Holdback Shares”), which converted into 1,560,400 shares of common stock out of the aggregate number of shares that the Flame Stockholders otherwise would be entitled to receive pursuant to the Merger so that Leap can have recourse to the Holdback Shares for purposes of satisfying certain claims for indemnification that Leap may have against the Flame Stockholders in connection with the Merger. In January 2024, Leap released the Holdback Shares to the Flame Shareholders.

On June 16, 2023, the Company obtained Stockholder Approval to convert the Series X Preferred Stock into shares of its common stock, which occurred on June 21, 2023.

The Company accounted for the acquisition of Flame as an asset acquisition allocating the purchase price under GAAP of$79,016 to net assets acquired. Although there is a presumption under SEC Rule 11-01(d) (“11-01(d)”) that when a legal entity is acquired, it represents a business acquisition, the Company concluded that, in this case, the transaction did not represent the acquisition of a business. After considering the criteria set forth in 11-01(d), the Company concluded that the acquisition of Flame by the Company was an acquisition of assets and not an acquisition of a business in accordance with 11-01(d). Specifically, the Company concluded that 1) the entity did not generate revenue and 2) there was not sufficient continuity of Flame’s operations prior to and following the transaction, in that no facilities, employees, sales force, distribution system, customer base, trade names or production techniques remained with the entity after the acquisition.

Leap primarily acquired cash of$50,362, certain working capital items ($928) and a portfolio of clinical- and pre-clinical-stage intellectual property, in connection with the acquisition of Flame. The Company accounted for the acquisition of Flame by recording the cash and any other assets and liabilities of Flame on its condensed consolidated balance sheet at their historical carrying values, which approximates fair values. The remaining fair value of the consideration transferred was allocated to the in-process research and development (“IPR&D”) assets acquired. Certain transaction costs that were not deemed to meet the criteria of costs directly attributable to the issuance of securities were capitalized in accordance with ASC 805-50-30-1 and recognized as part of fair value of assets acquired. As the Company concluded that such IPR&D does not have an alternative future use, the relative fair value allocated to acquired IPR&D of$29,582 was expensed in research and development expenses within the Company’s condensed consolidated statement of operations during the three months ended March 31, 2023.

In addition, subject to and upon the terms and conditions set forth in the Merger Agreement, the Company may also (i) pay Contingent Merger Consideration (as defined in the Merger Agreement) that may become payable if, and only if, certain assets of Flame related to Flame’s FL-101 program and/or FL-103 program are sold after the consummation of the Merger pursuant to the FL-101/103 Disposition Agreement (as defined in the Merger Agreement), which Contingent Merger Consideration shall be 80% of the after-tax net proceeds of such sale, if any, and the payment thereof is subject to the terms and conditions set forth in the Merger Agreement and (ii) issue pursuant to the Merger additional shares of Series X Preferred Stock or common stock as a result of any applicable post-closing purchase price adjustment in the event that Flame’s actual Company Net Cash (as defined in the Merger Agreement) as of the Effective Date is determined to be greater than Flame’s estimated Company Net Cash as of the closing.

Sale of FL - 101/FL - 103 to AlmataBio, Inc.

On December 6, 2023 the Company sold certain IPR&D assets previously acquired from Flame related to Flame’s FL - 101/FL - 103 program, including permits, clinical trial material, clinical data, and related identified contracts, such as licensing, research, clinical trials, and various other agreements. The Company received total consideration in the form of a non - refundable closing date cash payment of $500.

Pursuant to the terms of the asset purchase agreement, the Company is entitled to receive milestone payments of up to $70,000 upon achievement of certain regulatory approval and sales milestones specified in the asset purchase agreement.

The IPR&D assets sold related to Flame’s FL - 101/FL - 103 program did not meet the definition of a business and had a carrying value of $0 at the time of the sale. In addition, the Company estimated the likelihood of receiving any milestone payments to be

remote. As such, management elected the most likely amount method to determine the transaction price of the sale, which included the non - refundable closing date cash payment of $500 and future milestone payments of $0. Therefore, the Company recognized a non - operating gain in other income for the difference between the amount of non - refundable consideration received of $500 and the carrying value of $0 during the year ended December 31, 2023. In the event of a change in circumstances, such that it becomes likely that the Company will receive milestone payments, the Company will recognize income for the change in transaction price in the period in which the transaction price changes.

In addition, during the year ended December 31, 2023, the Company incurred various qualified expenses, such as legal fees, consulting and general and administrative expenses in connection with the sale of Flame’s FL - 101 program. Such expenses exceeded the non - refundable consideration received of $500, and therefore, the Company was not obligated to pay Contingent Merger Consideration to the Flame Stockholders.

Series X Preferred Stock

Pursuant to the Merger, the Company agreed to issue 136,248 shares of Series X Preferred Stock to Flame Stockholders and January 2023 Series X Preferred Stock Warrants for 443 shares of Series X Preferred Stock to Flame Warrant Holders. The Company obtained Stockholder Approval during the three months ended June 30, 2023 to convert each issued share of Series X Preferred Stock and each share of Series X Preferred Stock issuable pursuant to the January 2023 Series X Preferred Stock Warrants into 100 shares of its common stock. The Series X Preferred Stock was converted to common stock on June 21, 2023.

January 2023 Common Stock Warrants and January 2023 Series X Preferred Stock Warrants

In January 2023, pursuant to the Merger, the warrants held by the Flame Warrant Holders became exercisable for 6,530 shares of Leap’s common stock (the “January 2023 Common Stock Warrants”). The January 2023 Common Stock Warrants have an exercise price of $6.78 per share and expire in February 2025. The January 2023 Common Stock Warrants qualify for equity classification.

Also in January 2023, pursuant to the Merger, the warrants held by the Flame Warrant Holders became exercisable for 443 shares of Series X Preferred Stock (the “January 2023 Series X Preferred Stock Warrants”). Upon obtaining Stockholder Approval for the conversion of the Series X Preferred Stock and theone-for-ten reverse stock split, each share of Series X Preferred Stock converted into 100 shares of Common Stock. The January 2023 Series X Preferred Stock Warrants have an exercise price of $6.78 per share and expire in February 2025.

The Company initially recorded the January 2023 Series X Preferred Stock Warrants as a liability on the Effective Date and the warrant liability was subsequently remeasured to fair value at each reporting date and on the date on which Stockholder Approval to convert shares of Series X Preferred Stock into shares of common stock was obtained. On June 21, 2023, after obtaining stockholder approval for the conversion of the Series X Preferred Stock into common stock, the January 2023 Series X Preferred Stock Warrants were reclassified from liability to equity.

Changes in the fair value of the warrant liability are recognized as gains (losses) in the Company’s consolidated statement of operations. During the three months ended March 31, 2023, the Company recorded a gain of $50 in its condensed consolidated statement of operations.

4. Accrued Expenses

Accrued expenses consist of the following:

5. Leases

The Company has an operating lease for real estate in the United States and does not have any finance leases. The Company’s leases may contain options to renew and extend lease terms and options to terminate leases early. Reflected in the right-of-use asset and lease liability on the Company’s consolidated balance sheets are the periods provided by renewal and extension options that the Company is reasonably certain to exercise, as well as the periods provided by termination options that the Company is reasonably certain to not exercise.

The Company’s existing lease expires in July 2025 and includes variable lease and non-lease components that are not included in the right-of-use asset and lease liability and are reflected as an expense in the period incurred. Such payments primarily include common area maintenance charges.

In calculating the present value of future lease payments, the Company utilized its incremental borrowing rate based on the lease term. The Company has an existing net lease in which the non-lease components (e.g. common area maintenance, maintenance, consumables, etc.) are paid separately from rent based on actual costs incurred and therefore are not included in the right-of-use asset and lease liability and are reflected as an expense in the period incurred. During the six months ended June 30, 2024, the Company extended the term of its operating lease to July 31, 2025 and recorded an additional right-of-use asset and lease liability of$420. As of June 30, 2024, a right-of-use asset of $475 and lease liability of$482 are reflected on the condensed consolidated balance sheet. The Company recorded rent expense of$115 and$114, respectively, during the three months ended June 30, 2024 and 2023, and$225 and$228, respectively, during the six months ended June 30, 2024 and 2023. Cash paid for amounts included in the measurement of lease liabilities was$115 and$113, respectively, during the three months ended June 30, 2024 and 2023, and$229 and$226, respectively, during the six months ended June 30, 2024 and 2023.

Future lease payments under non-cancelable operating leases as of June 30, 2024 are detailed as follows:

6. Warrants

As of June 30, 2024, the number of shares of common stock issuable upon the exercise of outstanding warrants, consisted of the following:

2017 Warrants

The 2017 Warrants contain full ratchet anti-dilution protection provisions. The Company will recognize on a prospective basis the value of the effect of the down round feature in the warrant when it is triggered (i.e., when the exercise price is adjusted downward). This value is measured as the difference between (1) the financial instrument’s fair value (without the down round feature) using the pre-trigger exercise price and (2) the financial instrument’s fair value (with the down round feature) using the reduced exercise price.

The value of the effect of the down round feature will be treated as a dividend and a reduction to income available to common stockholders in the basic EPS calculation. In connection with the April 2024 Private Placement, when the 2017 Warrants were repriced from $10.55 to $2.82, the Company recorded a dividend of $234 during the three and six months ended June 30, 2024.

2019 Warrants

During the three months ended March 31, 2023, the Company redeemed 10,000 of the 2019 Warrants at a purchase price of $2.90 per share.

January 2023 Common Stock Warrants

In January 2023, pursuant to the Merger, the warrants held by the Flame Warrant Holders became exercisable for 6,530 shares of Leap’s common stock (the “January 2023 Common Stock Warrants”). The January 2023 Common Stock Warrants have an exercise price of $6.78 per share and expire in February 2025. The January 2023 Common Stock Warrants qualify for equity classification.

January 2023 Series X Preferred Stock Warrants

In January 2023, pursuant to the Merger, the warrants held by the Flame Warrant Holders also became exercisable for 443 shares of Series X Preferred Stock (the “January 2023 Series X Preferred Stock Warrants”). Following Stockholder Approval, each share of Series X Preferred Stock converted into 100 shares of common stock during the three months ended June 30, 2023. The January 2023 Series X Preferred Stock Warrants have an exercise price of $6.78 per share and expire in February 2025.

The Company initially recorded the January 2023 Series X Preferred Stock Warrants as a liability on its condensed consolidated balance sheet as of the Effective Date and subsequently remeasured the warrant liability to fair value at each reporting date and on the date Stockholder Approval was obtained to convert shares of Series X Preferred Stock into shares of common stock. Changes in the fair value of the warrant liability were recognized as gains (losses) in the Company’s consolidated statement of operations. During the three months ended March 31, 2023, the Company recorded a gain of $50 in its condensed consolidated statement of operations.

During the three months ended June 30, 2023, upon obtaining Stockholder Approval, the January 2023 Series X Preferred Stock Warrants were converted into common stock warrants and reclassified from liability to equity.

7. Common Stock

Each share of common stock entitles the holder toone 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, if any, subject to the preferential dividend rights of the preferred stockholders. Through June 30, 2024, no dividends have been declared for shares of common stock.

Acquisition of Flame – January 2023

8. Equity Incentive Plans

Equity Incentive Plans

On January 20, 2017, the Company’s stockholders approved the 2016 Equity Incentive Plan (the “2016 Plan”). Beginning on January 1, 2018, the number of shares of common stock authorized for issuance pursuant to the 2016 Plan was increased each January 1 by an amount equal to 4% of the Company’s outstanding common stock as of the end of the immediately preceding calendar year or such lesser amount as determined by the compensation committee of the Company’s Board of Directors.

On June 16, 2022, the Company’s stockholders approved the 2022 Equity Incentive Plan (the “2022 Plan”), which provides for a total of 750,000 new shares of the Company’s common stock to be granted. In addition, on June 16, 2023, stockholders approved 2,250,000 new shares of the Company’s common stock to be added to the 2022 Plan for future issuance.

As of June 30, 2024, there were 597,727 shares available for grant under the Company’s equity incentive plans.

A summary of stock option activity under the Equity Plans is as follows:

The grant date fair value of the options granted during the six months ended June 30, 2024 and 2023 was estimated at the date of grant using the Black-Scholes option valuation model. The expected life was estimated using the “simplified” method as defined by the SEC’s Staff Accounting Bulletin 107, Share-Based Payment. The expected volatility was based on the historical volatility of the Company. The risk-free interest rate was based on the continuous rates provided by the U.S. Treasury with a term approximating the expected life of the option. The expected dividend yield was 0% because the Company does not expect to pay any dividends for the foreseeable future. The Company elected the straight-line attribution method in recognizing the grant date fair value of options issued over the requisite service periods of the awards, which are generally the vesting periods.

The weighted average grant date fair value for the stock options granted during the six months ended June 30, 2024 and 2023 was $2.12 and $2.66 per share, respectively.

The assumptions that the Company used to determine the grant-date fair value of stock options granted to employees and directors during the six months ended June 30, 2024 and 2023 were as follows, presented on a weighted average basis:

Stock options generally vest over athree orfour year period, as determined by the compensation committee of the Board of Directors at the time of grant. The options expire 10 years from the grant date. As of June 30, 2024, there was approximately $6,542 of unrecognized compensation cost related to non-vested stock options, which is expected to be recognized over a remaining weighted-average period of approximately 2.06 years.

Restricted Stock Units (“RSUs”)

The Company did not grant any RSUs during the six months ended June 30, 2024 and 2023.

The following table presents RSU activity under the 2016 Plan during the six months ended June 30, 2024:

As of June 30, 2024, there were 227,500 shares outstanding covered by RSUs that are expected to vest with a weighted average grant date fair value of $19.29 per share and an aggregate grant date fair value of approximately $4,388. As of June 30, 2024, there was approximately $884 of unrecognized compensation costs related to RSUs granted to employees, which are expected to be recognized as expense over a remaining weighted average period of 0.62 years.

The Company recognized stock-based compensation expense related to the issuance of stock option awards and RSUs to employees and non-employees in the condensed consolidated statements of operations during the three and six months ended June 30, 2024 and 2023 as follows:

Stock Based Compensation Expense

9. Net Loss Per Share

Basic and diluted net loss per share for the three and six months ended June 30, 2024 and 2023 was calculated as follows (in thousands except share and per share amounts).

Included within weighted average common shares outstanding for the three and six months ended June 30, 2024 and 2023 are 2,945,175 common shares issuable upon the exercise of certain warrants, which are exercisable at any time for nominal consideration, and as such, the shares are considered outstanding for the purpose of calculating basic and diluted net loss per share attributable to common stockholders.

All warrants exercisable for common stock participate on a one-for-one basis and shares and warrants exercisable for Series X Preferred Stock issued participate on an as converted basis with common stock in the distribution of dividends, if and when declared by the board of directors, on the Company’s common stock. For purposes of computing EPS, these securities are considered to participate with common stock in earnings of the Company. Therefore, the Company calculates basic and diluted EPS using the two-class method. Under the two-class method, net income for the period is allocated between common stockholders and participating securities according to dividends declared and participation rights in undistributed earnings. No income was allocated to the warrants and Series X Preferred Stock for the six months ended June 30, 2024 and 2023, as results of operations were a loss for the period.

The Company’s potentially dilutive securities include RSUs, stock options and warrants. These securities were excluded from the computations of diluted net loss per share for the three and six months ended June 30, 2024 and 2023, as the effect would be to reduce the net loss per share. The following table includes the potential shares of common stock, presented based on amounts outstanding at each period end, that were excluded from the computation of diluted net loss per share attributable to common stockholders for the periods indicated because including them would have had an anti-dilutive effect:
