1. NATURE OF OPERATIONS AND BASIS OF PRESENTATION

Business

Acer Therapeutics Inc., a Delaware corporation (the “Company”), is a pharmaceutical company focused on the acquisition, development, and commercialization of therapies for serious rare and life-threatening diseases with significant unmet medical needs. The Company’s pipeline includes four programs: ACER-001 (sodium phenylbutyrate) for the treatment of various inborn errors of metabolism, including urea cycle disorders (“UCDs”) and Maple Syrup Urine Disease (“MSUD”); ACER-801 (osanetant) for the treatment of induced vasomotor symptoms (“iVMS”); EDSIVO™ (celiprolol) for the treatment of vascular Ehlers-Danlos syndrome (“vEDS”) in patients with a confirmed type III collagen (COL3A1) mutation; and ACER-2820 (emetine), a host-directed therapy against a variety of viruses, including cytomegalovirus, zika, dengue, ebola and COVID-19. Each of the Company’s product candidates is believed to present a comparatively de-risked profile, having one or more of a favorable safety profile, clinical proof-of-concept data, mechanistic differentiation, and/or accelerated pathways for development through specific programs and procedures established by the United States (“U.S.”) Food and Drug Administration (“FDA”).

Since its inception, the Company has devoted substantially all of its efforts to business planning, research and development, recruiting management and technical staff, acquiring operating assets, and raising capital. The Company has generated revenue related to the collaboration and license agreement (the “Collaboration Agreement”) with Relief Therapeutics Holding AG (“Relief”) as described below but has not generated any product revenue to date and may never generate any product revenue in the future.

Liquidity

The Company had an accumulated deficit of $114.5 million and cash and cash equivalents of $12.7 million as of December 31, 2021. Net cash used in operating activities was $0.1 million and $17.0 million for the years ended December 31, 2021 and 2020, respectively.

On November 9, 2018, the Company entered into a sales agreement with Roth Capital Partners, LLC, and on March 18, 2020, an amended and restated sales agreement was entered into with JonesTrading Institutional Services LLC and Roth Capital Partners, LLC. The agreement provides a facility for the offer and sale of shares of common stock from time to time having an aggregate offering price of up to $50.0 million depending upon market demand, in transactions deemed to be an at-the-market (“ATM”) offering. The Company has no obligation to sell any shares of common stock pursuant to the agreement and may at any time suspend sales pursuant to the agreement. Each party may terminate the agreement at any time without liability. From May 19, 2020 through December 31, 2020, during multiple trading days, the Company sold an aggregate of 1,838,957 shares of common stock at an average gross sale price of $3.9228 per share, for gross proceeds of $7.2 million. Gross proceeds, net of $0.3 million of fees and offering costs, resulted in net proceeds of $6.9 million. During the year ended December 31, 2021, during multiple trading days, the Company sold an aggregate of 877,107 shares at an average gross sale price of $3.1692 per share, resulting in gross proceeds of $2.8 million. Gross proceeds, net of $0.2 million of fees and offering costs, resulted in net proceeds of $2.6 million during the year ended December 31, 2021. As of December 31, 2021, $40.0 million remained available under the Company’s ATM facility.

On April 30, 2020, the Company entered into an equity line purchase agreement and registration rights agreement pursuant to which Lincoln Park Capital Fund, LLC (“Lincoln Park”) has committed to purchase up to $15.0 million of the Company’s common stock. Under the terms and subject to the conditions of the purchase agreement, the Company has the right, but not the obligation, to sell to Lincoln Park, and Lincoln Park is obligated to purchase up to $15.0 million of the Company’s common stock, with $12.1 million obligation remaining as of December 31, 2021. Such sales of common stock by the Company will be subject to certain limitations, and may

104

occur from time to time, at the Company’s sole discretion, over the 36-month period commencing on June 8, 2020. The number of shares the Company may sell to Lincoln Park on any single business day in a regular purchase is 50,000, but that amount may be increased up to 100,000 shares, depending upon the market price of the Company’s common stock at the time of sale and subject to a maximum limit of $1.0 million per regular purchase. The purchase price per share for each such regular purchase will be based on prevailing market prices of the Company’s common stock immediately preceding the time of sale as computed under the purchase agreement. In addition to regular purchases, the Company may also direct Lincoln Park to purchase other amounts as accelerated purchases or as additional accelerated purchases if the closing sale price of the common stock exceeds certain threshold prices as set forth in the purchase agreement. The Company issued 148,148 shares of common stock to Lincoln Park as a commitment fee in connection with entering into the purchase agreement. The $0.4 million fair value of the commitment fee shares was recorded to General and administrative expense along with other costs incurred in connection with entering into the purchase agreement. During the year ended December 31, 2020, the Company sold 900,000 shares of common stock under our purchase agreement with Lincoln Park at a weighted average gross sale price of $2.64 per share, resulting in gross proceeds of $2.4 million. Gross proceeds, net of $0.2 million of offering costs, resulted in net proceeds of $2.2 million. During the year ended December 31, 2021, the Company sold 200,000 shares of common stock under its purchase agreement with Lincoln Park at a weighted average gross sale price of $2.47 per share, resulting in proceeds of $0.5 million.

On July 24, 2020, the Company entered into a securities purchase agreement for the sale and issuance of an aggregate of 244,998 shares of the Company’s common stock, for an aggregate purchase price of $0.9 million, in a private placement transaction (“Private Placement”) with certain directors, officers, and employees at a price per share of $3.50. The shares of common stock issued in the Private Placement constitute “restricted securities” under the federal securities laws and are subject to a minimum six-month holding period.

On January 25, 2021, the Company entered into the Option Agreement with Relief, pursuant to which the Company granted Relief an exclusive option (the “Exclusivity Option”) to pursue a potential collaboration and license arrangement with the Company for the development, regulatory approval and commercialization of ACER-001 for the treatment of various inborn errors of metabolism, including UCDs and MSUD. The Option Agreement provided a period of time up to June 30, 2021, for the parties to perform additional due diligence and to work toward negotiation and execution of a definitive agreement with respect to the potential collaboration for ACER‑001. In consideration for the grant of the Exclusivity Option, (i) the Company received from Relief an upfront nonrefundable payment of $1.0 million, (ii) Relief provided to the Company a 12-month secured loan in the principal amount of $4.0 million, as evidenced by a Promissory Note (the “Note”) the Company issued to Relief, and (iii) the Company granted Relief a security interest in all of its assets to secure performance of the Note, as evidenced by a Security Agreement (the “Security Agreement”). The Note was repayable in one lump sum within 12 months from issuance and bore interest at a rate equal to 6% per annum. If a definitive agreement with respect to the potential collaboration had not been executed by the parties on or before June 30, 2021, the Exclusivity Option would have terminated, and the Note would have been repayable by the Company upon maturity.

On March 19, 2021, the Company entered into a Collaboration Agreement with Relief providing for the development and commercialization of ACER-001 for the treatment of various inborn errors of metabolism, including for the treatment of UCDs and MSUD. The Collaboration Agreement is the culmination of the option agreement (the “Option Agreement,” together the “Agreements”) previously entered into between the Company and Relief on January 25, 2021. Pursuant to the Agreements, the Company received from Relief an upfront non-refundable payment of $1.0 million and a reimbursement payment (the “Reimbursement Payment”) of $14.0 million, and Relief released its security interest in all of the Company’s assets. Under the terms of the Collaboration Agreement, Relief committed to pay the Company up to $20.0 million for U.S. development and commercial launch costs for the UCDs and MSUD indications (the “Development Payments”). During the three months ended June 30, 2021, the Company received from Relief the $10.0 million First Development Payment. The Company was contractually entitled to receive from Relief an additional $10.0 million Second Development Payment conditioned upon FDA’s acceptance of a New Drug Application (“NDA”) for ACER-001 in a UCD for filing and review. This acceptance was received on October 4, 2021. On October 6, 2021, the Company entered into a Waiver and Agreement with Relief to amend the timing for the Second Development Payment. The Company received the Second Development Payment in two $5.0 million tranches on each of October 12, 2021 and January 14, 2022. Further, the Company retained development and commercialization rights in the U.S., Canada, Brazil, Turkey, and Japan (“Acer Territory”). The companies will split net profits from the Acer Territory 60%:40% in favor of Relief.

105

Relief licensed the rights for the rest of the world (“Relief Territory”), where the Company will receive from Relief a 15% royalty on all net sales received in the Relief Territory. The Company could also receive a total of $6.0 million in milestone payments based on the first European marketing approvals of ACER-001 for a UCD and MSUD. There is no guarantee that ACER-001 will receive regulatory authority approval in any territory or become commercially available for the indications under investigation. The terms of the Agreements are further described below in the Revenue Recognition and Accounting for Collaboration Agreements section of Note 2, Significant Accounting Policies.

The Company’s existing cash and cash equivalents available at December 31, 2021, plus the $5.0 million second tranche of the Second Development Payment received on January 14, 2022 per the Collaboration Agreement with Relief, will be sufficient to fund the Company’s anticipated operating and capital requirements into mid-2022, excluding support for planned ACER-001 (MSUD), ACER-801 and EDSIVO^TM clinical trials.

Management expects to continue to finance operations through the issuance of additional equity or debt securities, non-dilutive funding, and/or through strategic collaborations. Any transactions which occur may contain covenants that restrict the ability of management to operate the business and any securities issued may have rights, preferences, or privileges senior to the Company’s common stock and may dilute the ownership of current stockholders of the Company.

Going Concern

The accompanying financial statements have been prepared in conformity with accounting principles generally accepted in the U.S. (“GAAP”), which contemplate continuation of the Company as a going concern. The Company has not established a source of commercial product revenues and, as such, has been dependent on funding operations through the sale of equity securities and through a collaboration agreement. Since inception, the Company has experienced significant losses and incurred negative cash flows from operations. The Company has spent, and expects to continue to spend, a substantial amount of funds in connection with implementing its business strategy, including its planned product development efforts and potential precommercial activities.

As of December 31, 2021, the Company had cash and cash equivalents of $12.7 million and current liabilities of $29.1 million, which include $15.8 million associated with deferred collaboration funding (see Revenue Recognition and Accounting for Collaboration Agreements below in Note 2, Significant Accounting Policies), as well as a $9.3 million liability related to the securities class action and stockholder derivative actions settlements and legal costs, for which the Company has also recorded an asset of an equal amount representing the recovery from its insurance carriers. The Company’s cash and cash equivalents available at December 31, 2021, plus the $5.0 million second tranche of the Second Development Payment received on January 14, 2022 per the Collaboration Agreement with Relief, are expected to fund our anticipated operating and capital requirements into mid-2022, excluding support for planned ACER-001 (MSUD), ACER-801 and EDSIVO^TM clinical trials.

The Company will need to raise additional capital to fund continued operations beyond mid-2022 because neither FDA approval of ACER-001 nor subsequent product revenues are assured. The Company may not be successful in its efforts to raise additional funds or achieve profitable operations. The Company continues to explore potential opportunities and alternatives to obtain the additional resources that will be necessary to support its ongoing operations through and beyond the next 12 months, including raising additional capital through either private or public equity or debt financing or non-dilutive funding, as well as using its ATM facility and/or its remaining $12.1 million equity line facility entered into on April 30, 2020 with Lincoln Park, which is subject to certain limitations and conditions. As of December 31, 2021, $40.0 million remained available under the Company’s ATM facility. (See At-the-Market Facility and Common Stock Purchase Agreement below in Note 7 Stockholders’ (Deficit) Equity.) The Company has no commitments for any additional financing except for the agreement with Lincoln Park and the Collaboration Agreement with Relief. Any amounts raised will be used for further development of its product candidates, precommercial activities, and for other working capital purposes.

If the Company is unable to obtain additional funding to support its current or proposed activities and operations, it may not be able to continue its operations as proposed, which may require it to suspend or terminate any ongoing development activities, modify its business plan, curtail various aspects of its operations, cease

106

operations, or seek relief under applicable bankruptcy laws. In such event, the Company’s stockholders may lose a substantial portion or even all of their investment.

These factors individually and collectively raise substantial doubt about the Company’s ability to continue as a going concern for at least 12 months from the date these financial statements are available, or March 2, 2022. The accompanying financial statements do not include any adjustments or classifications that may result from the possible inability of the Company to continue as a going concern.
