Note 1 - Organization and Description of Business Operations

Checkpoint Therapeutics, Inc. (the “Company” or “Checkpoint”) was incorporated in Delaware on November 10, 2014. Checkpoint is a clinical-stage immunotherapy and targeted oncology company focused on the acquisition, development and commercialization of novel treatments for patients with solid tumor cancers. The Company may acquire rights to these technologies by licensing the rights or otherwise acquiring an ownership interest in the technologies, funding their research and development and eventually either out-licensing or bringing the technologies to market. The Company may also enter into collaboration agreements with third and related parties including sponsored research agreements to develop these technologies for liquid tumors while retaining the rights in solid tumors.

The Company is a majority-controlled subsidiary of Fortress Biotech, Inc. (“Fortress”).

The Company’s common stock is listed on the NASDAQ Capital Market and trades under the symbol “CKPT.”

Reverse Stock Split

On November 3, 2022, the holders of a majority of the voting power of the common stock of the Company executed a written consent approving a grant of discretionary authority to the board of directors of the Company (the “Board”) to, without further stockholder approval, (i) effect a 1:10 reverse stock split of the Company’s issued and outstanding common stock (the “Reverse Stock Split”), (ii) effect a change in the number of the Company’s authorized shares from 13,500,000 to 50,000,000 by filing an amendment (the “Certificate Amendment”) to the Company’s Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware, and (iii) effect an amendment to the Company’s Amended and Restated 2015 Incentive Plan to increase the number of shares issuable thereunder, after giving effect to the Reverse Stock Split, from 900,000 to 3,000,000 (the “Plan Amendment”). The written consent was signed by the holders of 10,914,552 shares of the Company’s common stock and 7,000,000 shares of the Company’s Class A Common Stock, before giving effect to the Reverse Stock Split. Each share of common stock entitles the holder thereof to one vote on all matters submitted to stockholders and each share of Class A Common Stock has the voting power of 1.1 times a fraction, the numerator of which is the sum of the shares of outstanding common stock and the denominator of which is the number of shares of outstanding Class A Common Stock, or approximately 13.5 votes per share as of November 3, 2022. Accordingly, the holders of approximately 58% of the voting power of the Company’s common stock as of November 3, 2022, signed the written consent approving the Reverse Stock Split, the Certificate Amendment, and the Plan Amendment. The Board also approved the Reverse Stock Split, the Certificate Amendment, and the Plan Amendment.

Pursuant to rules adopted by the Securities and Exchange Commission (“SEC”) under the Securities Exchange Act of 1934, a Schedule 14C information statement was filed with the SEC and provided to the stockholders of the Company. The Reverse Stock Split became effective on December 6, 2022, or twenty (20) days from the mailing of the information statement to the common stockholders of record.  The Authorized Share Reduction also became effective on December 6, 2022 per the Certificate Amendment filed with the Secretary of State of the State of Delaware.

All share and per share information has been retroactively adjusted to give effect to the Reverse Stock Split for all periods presented, unless otherwise indicated. Proportionate adjustments were made to the per share exercise price and/or the number of shares issuable upon the exercise or vesting of all stock options, restricted stock and warrants outstanding at December 6, 2022, which resulted in a proportional decrease in the number of shares of the Company’s common stock reserved for issuance upon exercise or vesting of such stock options, restricted stock and warrants, and, in the case of stock options and warrants, a proportional increase in the exercise price of all such stock options and warrants.

No fractional shares were issued in connection with the Reverse Stock Split and stockholders who would otherwise be entitled to a fraction of one share received a proportional cash payment.

Liquidity, Capital Resources and Going Concern

The Company has incurred substantial operating losses since its inception and expects to continue to incur significant operating losses for the foreseeable future and may never become profitable. As of December 31, 2022, the Company had an accumulated deficit of $262.5 million.

In December 2022, the Company closed on a registered direct offering (the “December 2022 Registered Direct Offering”) with a single institutional investor for the issuance and sale of 950,000 shares of its common stock and 784,105 pre-funded warrants (the “Pre-Funded Warrants). Each Pre-Funded Warrant was exercisable for one share of our common stock. The common stock and the Pre-Funded Warrants were sold together with Series A warrants to purchase up to 1,734,105 shares of common stock and Series B warrants to purchase up to 1,734,105 shares of common stock (collectively, the “December 2022 Common Stock Warrants”), at a purchase price of $4.325 per share of common stock and associated December 2022 Common Stock Warrants, and $4.33249 per Pre-Funded Warrant and associated December 2022 Common Stock Warrants. The Pre-Funded Warrants were funded in full at closing except for a nominal exercise price of $0.0001 and are exercisable commencing on the closing date and will terminate when such Pre-Funded Warrants are exercised in full. The Series A warrants are exercisable immediately upon issuance and will expire five years following the issuance date and have an exercise price of $4.075 per share and the Series B warrants are exercisable immediately upon issuance and will expire eighteen months following the issuance date and have an exercise price of $4.075 per share. Net proceeds from the December 2022 Registered Direct Offering were $6.7 million after deducting commissions and other transaction costs.

During the year ended December 31, 2022, the Company sold a total of 532,816 shares of common stock under an At-the-Market Issuance Sales Agreement (the “ATM”) for aggregate total gross proceeds of approximately $10.1 million at an average selling price of $18.99 per share, resulting in net proceeds of approximately $9.9 million after deducting commissions and other transaction costs.

The Company expects to continue to use the proceeds from previous financing transactions primarily for general corporate purposes, which may include financing the Company’s growth, developing new or existing product candidates, and funding capital expenditures, acquisitions and investments.

In accordance with Accounting Standards Codification ("ASC") 205-40, Going Concern, the Company evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about its ability to continue as a going concern within one year after the date that these financial statements are issued. This evaluation initially does not take into consideration the potential mitigating effect of management's plans that have not been fully implemented as of the date the financial statements are issued. When substantial doubt exists under this methodology, management evaluates whether the mitigating effect of its plans sufficiently alleviates substantial doubt about the Company's ability to continue as a going concern. The mitigating effect of management's plans, however, is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that the financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that these consolidated financial statements are issued. In performing its analysis, management excluded certain elements of its operating plan that cannot be considered probable. Under ASC 205-40, the future receipt of potential funding from future equity or debt issuances and other potential sources such as partnerships cannot be considered probable at this time because these plans are not entirely within the Company's control nor have these plans been approved by the Board of Directors as of the date of these financial statements.

As of December 31, 2022, the Company had cash and cash equivalents of $12.1 million. The Company believes that its cash and cash equivalents are only sufficient to fund its operating expenses into the second quarter of 2023. The Company's expectation to generate operating losses and negative operating cash flows in the future and the need for additional funding to support its planned operations raise substantial doubt regarding the Company's ability to continue as a going concern for a period of one year after the date that these financial statements are issued. Management's plans to alleviate the conditions that raise substantial doubt include reduced 2023 spending, including projected savings through delaying the development timelines of certain programs and the pursuit of additional cash resources through public or private equity or debt financings and potential partnerships. Management has concluded the likelihood that its plan to successfully obtain sufficient funding from one or more of these sources, or adequately reduce expenditures, while reasonably possible, is less than probable. Accordingly, the Company has concluded that substantial doubt exists about the Company's ability to continue as a going concern for a period of at least 12 months from the date of issuance of these financial statements. The Company’s estimate as to how long it expects its existing cash to be able to continue to fund its operations is based on assumptions that may prove

to be wrong, and it could use its available capital resources sooner than it currently expects. Further, changing circumstances, some of which may be beyond its control, could cause the Company to consume capital faster than it currently anticipates, and it may need to seek additional funds sooner than planned. The Company cannot be certain that additional funding will be available to it on acceptable terms, or at all.

The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of the uncertainties described above.

The Company does not expect any material impact on its long-term development timeline and its liquidity due to the worldwide spread of COVID-19.
