SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

Various statements made in this Quarterly Report on Form 10-Q are forward-looking and involve risks and uncertainties. All statements that address activities, events or developments that we intend, expect or believe may occur in the future are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Such statements give our current expectations or forecasts of future events and are not statements of historical or current facts. These statements include, among others, statements about:

•the Company's expectation regarding the exploration of strategic alternatives;

•the Company's ongoing strategy, including reducing its expenditures on research and development activities and taking other cost savings measures in connection with the Company's ongoing review of strategic alternatives;

•the Company's ongoing comprehensive review of strategic alternatives;

•the Company's ability to continue as a going concern and its ability to obtain additional capital to support its operations through the first quarter of 2024;

•estimated costs associated with the Company’s cost savings plan;

•the Company’s ability to preserve capital while it continues to assess potential strategic alternatives;

•the expected timing for incurring costs associated with the cost savings plan;

•the Company's clinical trials, including expected costs, goals, timing and other expectations related thereto;

•the Company's plan to submit an amendment to the Ewing sarcoma clinical trial protocol;

•the potential advantages of its lead compound, seclidemstat or SP-2577, as a treatment for Ewing sarcoma, and other cancers and its ability to improve the life of patients;

•the potential for seclidemstat to target the epigenetic dysregulation underlying Ewing sarcoma and advanced solid tumors;

•the future of the company’s Phase 1/2 trial of seclidemstat as a treatment for Ewing sarcoma and FET-rearranged sarcomas;

•the potential advantages of protein degraders including the value of SP-3164 as a cancer treatment;

•the commercial or market opportunity and expansion for each therapeutic option, including the availability and value of a pediatric priority review voucher for in-clinic treatments and potential for accelerated approval;

•the Company’s expectations as to revenue, cash flow, and expenses; and

•the Company's liquidity position, the expected insufficiency of such position to support anticipated operating and capital requirements;

Forward-looking statements also include statements other than statements of current or historical fact, including, without limitation, all statements related to any expectations of revenues, expenses, cash flows, earnings or losses from operations, cash required to maintain current and planned operations, capital or other financial items; any statements of the plans, strategies and objectives of management for future operations; any plans or expectations with respect to product research, development and commercialization, including regulatory approvals; any other statements of expectations, plans, intentions or beliefs; and any statements of assumptions underlying any of the foregoing. We often, although not always, identify forward-looking statements by using words or phrases such as “believe,” “may,” “could,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “indicate,” “seek,” “should,” “would,” “target”, “potential,” “evaluate,” “proceeding.”

The following are some of the factors that could cause actual results to differ materially from the anticipated results or other expectations expressed, anticipated or implied in our forward-looking statements:

•uncertainties about the exploration and evaluation of strategic alternatives, including that they may not result in a definitive transaction or enhance stockholder value and may create a distraction or uncertainty that may adversely affect our operating results, business or investor perceptions;

•potential adverse impacts resulting from our announcement regarding our board of directors’ review of potential strategic alternatives for the Company;

•the impact of the workforce reduction on the Company’s business;

•the risk that the Company’s cost saving initiatives may not be successful;

Table of Contents

•unanticipated difficulties with preserving capital;

•unanticipated charges not currently contemplated that may occur as a result of the Company’s cost savings plan;

•uncertainties about the paths of our programs and our ability to evaluate and identify a path forward for

those programs, particularly given the constraints we have as a small company with limited financial,

personnel and other operating resources;

• the risk that we could be delisted from Nasdaq, which would seriously harm the liquidity of our stock and our ability to raise capital;

•our ability to raise additional capital;

•the risk that if we do not successfully complete a strategic transaction or obtain financing in the near term, our board of directors may decide to pursue a dissolution and liquidation of our Company;

•the effectiveness and timeliness of our preclinical studies and possible future clinical trials, and the usefulness of the data;

•the adequacy of our capital to support our future operations

•fluctuations in our operating results;

•the success of current and future license and collaboration agreements;

•our dependence on contract research organizations, vendors and investigators;

•effects of competition and other developments affecting development of products;

•market acceptance of our product candidates;

•protection of intellectual property and avoiding intellectual property infringement;

•product liability; and

•other factors described in our filings with the SEC.

We cannot guarantee that the results and other expectations expressed, anticipated or implied in any forward-looking statement will be realized. The risks set forth under Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, as supplemented by Part II, Item 1A of this Quarterly Report on Form 10-Q, describe major risks to our business, and you should read and interpret any forward-looking statements together with these risks. A variety of factors, including these risks, could cause our actual results and other expectations to differ materially from the anticipated results or other expectations expressed, anticipated or implied in our forward-looking statements. Should known or unknown risks materialize, or should underlying assumptions prove inaccurate, actual results could differ materially from past results and those anticipated, estimated or projected in the forward-looking statements. You should bear this in mind as you consider any forward-looking statements.

Our forward-looking statements speak only as of the dates on which they are made. We do not undertake any obligation to publicly update or revise our forward-looking statements even if experience or future changes makes it clear that any projected results expressed or implied in such statements will not be realized.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

NOTE 1. ORGANIZATION AND OPERATIONS

Nature of Business

Salarius Pharmaceuticals, Inc. (“Salarius” or the “Company”), together with its subsidiaries, Salarius Pharmaceuticals, LLC, Flex Innovation Group LLC, and TK Pharma, Inc., is a clinical-stage biopharmaceutical company focused on developing effective treatments for cancers with high, unmet medical need. Specifically, the Company is developing treatments for cancers caused by dysregulated gene expression, i.e., genes that are incorrectly turned on or off. The Company is developing two classes of drugs that address gene dysregulation: targeted protein inhibitors and targeted protein degraders. The Company's technologies have the potential to work in both liquid and solid tumors. The Company's current pipeline consists of two small molecule drugs: 1) SP-3164, a targeted protein degrader, and 2) seclidemstat (SP-2577), a targeted protein inhibitor. The Company is located in Houston, Texas.

Going Concern

Salarius has no products approved for commercial sale, has not generated any revenue from product sales to date and has suffered recurring losses from operations since its inception. The lack of revenue from product sales to date and recurring losses from operations since its inception raise substantial doubt as to the Company's ability to continue as a going concern. The accompanying financial statements are prepared using accounting principles generally accepted in the United States applicable to a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts and classification of liabilities should the Company be unable to continue as a going concern. Salarius will require substantial additional capital to fund its research and development expenses related to its pipeline including SP-3164 and seclidemstat. Based on Salarius’ expected cash requirements, Salarius believes that there is substantial doubt that its existing cash and cash equivalents, will be sufficient to fund its operations through one year from the financial statements' issuance date. The Company may attempt to obtain additional capital through the sale of equity securities in one or more offerings or through issuances of debt instruments, and may also consider new collaborations or selectively partnering its technology. However, the Company cannot provide any assurance that it will be successful in accomplishing any of its plans.

Although the Company is currently exploring various strategic alternatives, these strategic alternatives may not be successful in the next several months prior to its cash position getting to the point that it will need to pursue the winding down and dissolution of the Company. If the Company does not raise capital or successfully engage a strategic partner in the next several months, it will be forced to cease operations, liquidate assets and possibly seek bankruptcy protection or engage in a similar process.

Recent Developments

Strategic Alternatives

On August 8, 2023 the Company announced it had retained Canaccord Genuity, LLC to lead a comprehensive review of strategic alternatives focusing on maximizing shareholder value, including but not limited to, an acquisition, merger, reverse merger, divestiture of assets, licensing, or other strategic transactions involving the Company. However, there is no set timetable for this process and there can be no assurance that this process will result in the Company pursuing a transaction or that any transaction, if pursued, will be completed on attractive terms. If the Company is unable to complete a transaction, it may be necessary to seek other alternatives for restructuring and resolving its liabilities, including an orderly wind-down. Salarius does not expect to disclose developments with respect to this process unless and until the evaluation of strategic alternatives has been completed or the Board of Directors has concluded that disclosure is appropriate or legally required.

In connection with the evaluation of strategic alternatives and in order to extend its resources, Salarius implemented a cost-savings plan that includes a reduction in workforce by over 50% of its positions, with remaining employees focusing primarily on limited drug development activities, completing the US Food and Drug Administration (the "FDA") process to determine the clinical trial registration requirements for the seclidemstat Ewing sarcoma program and supporting the exploration of strategic alternatives.

Table of Contents

In connection with the cost-savings plan, the Company has recognized approximately $0.3 million separation costs during the third quarter of 2023 of which, $0.1 million is included as accrued expense and other current liabilities on the Company's condensed consolidated balance sheet as of September 30, 2023.

NASDAQ Minimum Bid Compliance

On September 5, 2023, the Company was notified (the “Notice”) by Nasdaq Stock Market, LLC (“Nasdaq”) that on September 1, 2023, the average closing price of the Company’s common stock (the “Common Stock”) over the prior 30 consecutive trading days had fallen below $1.00 per share, which is the minimum average closing price required to maintain listing on Nasdaq under Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Requirement”).

The Notice has no immediate effect on the listing or trading of the Company’s common stock. In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company has 180 calendar days to regain compliance with the Minimum Bid Requirement. To regain compliance, the closing bid price of the Company’s common stock must be at least $1.00 per share for a minimum of ten consecutive business days before March 4, 2024.

If the Company does not achieve compliance with the Minimum Bid Requirement during the initial 180 calendar day period, the Company may be eligible for an additional 180 calendar day compliance period. To qualify, the Company would be required to meet the continued listing requirement for market value of publicly held shares and all other Nasdaq initial listing standards, with the exception of the Minimum Bid Requirement, and would need to provide written notice of its intention to cure the deficiency during the second compliance period. However, if it appears to Nasdaq staff that the Company will not be able to cure the deficiency, or if the Company does not meet the other listing standards, Nasdaq could provide notice that the Company’s common stock will become subject to delisting. In the event the Company receives notice that its common stock is being delisted, Nasdaq rules permit the Company to appeal any delisting determination by the Nasdaq staff to a Hearings Panel.

There can be no assurance that the Company will be able to regain compliance with the Minimum Bid Requirement or maintain compliance with the other listing requirements.

The Company intends to actively monitor the closing bid price of its common stock and will evaluate available options to regain compliance with the Minimum Bid Requirement.

End of Phase 2 Meeting with FDA

On October 13, 2023 the Company met with the FDA to identify activities necessary to seek US registration of SP-2577 as a treatment for Ewing sarcoma. The Company is in the process of implementing the initial activities that the Company believes it aligned with the FDA during the end of Phase 2 meeting process.

Based on the advice received from the FDA and clinical data shared during the meeting process, the Company is preparing an amendment to the Ewing sarcoma clinical trial protocol and plans to submit that protocol in the forth quarter of 2023.

NOTE 2. BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States ("GAAP"). Any reference in these notes to applicable guidance is meant to refer to the authoritative GAAP as found in the Accounting Standard Codification ("ASC") and Accounting Standards Update ("ASU") of the Financial Accounting Standards Board ("FASB").

On October 14, 2022, the Company filed a Certificate of Amendment to the Company’s restated certificate of incorporation with the Secretary of State of the State of Delaware to effect a 1-for-25 reverse stock split of the Company’s issued and outstanding shares of common stock, par value $0.0001 per share (the “Reverse Stock Split”), which became effective on October 14, 2022. All historical share and per share amounts reflected throughout this report have been adjusted to reflect the Reverse Stock Split.

Principles of Consolidation

Table of Contents

The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.

Unaudited Interim Financial Information

The accompanying interim financial statements are unaudited. These unaudited interim financial statements have been prepared in accordance with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. These unaudited interim financial statements should be read in conjunction with the audited financial statements and accompanying notes for the year ended December 31, 2022 included elsewhere in the Company's Annual Report on Form 10-K filed with the SEC on March 27, 2023. In the opinion of management, the unaudited interim financial statements reflect all the adjustments (consisting of normal recurring adjustments) necessary to state fairly the Company’s financial position as of September 30, 2023 and the results of operations for the three and nine months ended September 30, 2023 and 2022. The interim results of operations are not necessarily indicative of the results that may occur for the full fiscal year. The December 31, 2022 balance sheet included herein was derived from the audited financial statements, but does not include all disclosures, including notes, required by GAAP for complete financial statements.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America as defined by the FASB ASC requires management to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results could differ from those estimates.

Cash and Cash Equivalents

Salarius considers all highly liquid investments with original maturities of three months or less to be cash equivalents.

Impairment of Long-Lived Assets

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that their carrying value may not be recoverable. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. There were no impairment charges related to long-lived assets during 2022 or for the nine months ended September 30, 2023.

Goodwill

Goodwill is not amortized, but is tested at least annually for impairment at the reporting unit level. The Company has determined that the reporting unit is the single operating segment disclosed in its current financial statements. Additional impairment assessments may be performed on an interim basis if the Company encounters events or changes in circumstances that would indicate that, more likely than not, the carrying value of goodwill has been impaired.

Impairment is the condition that exists when the carrying amount of goodwill exceeds its implied fair value. The Company utilizes the option to perform a qualitative assessment for its reporting unit and if the Company concludes it is more likely than not that the fair value of the reporting unit is less than its carrying amount, then the Company utilizes the two-step quantitative assessment. The Company’s qualitative assessment is sensitive to assumptions related to potential adverse events and circumstances, including current market trends in control premiums and involves judgement in determining comparable peer companies to include in the control premium evaluation. The Company recorded goodwill impairment loss of $8.9 million during the three and nine month ended September 30, 2022.

Financial Instruments and Credit Risks

Financial instruments that potentially subject the Company to credit risk include cash and cash equivalents and restricted cash. Cash is deposited in demand accounts in federally insured domestic institutions to minimize risk.

Table of Contents

Insurance is provided through the Federal Deposit Insurance Corporation. Although the balances in these accounts exceed the federally insured limit from time to time, the Company has not incurred losses related to these deposits.

Warrants

The Company determines whether warrants should be classified as a liability or equity. For warrants classified as liabilities, the Company estimates the fair value of the warrants at each reporting period using Level 3 inputs with changes in fair value recorded in the Condensed Consolidated Statement of Operations within change in fair value of warrant liability. The estimates in valuation models are based, in part, on subjective assumptions, including but not limited to stock price volatility, the expected life of the warrants, the risk-free interest rate and the fair value of the common stock underlying the warrants, and could differ materially in the future. The Company will continue to adjust the fair value of the warrant liability at the end of each reporting period for changes in fair value from the prior period until the earlier of the exercise or expiration of the applicable warrant. For warrants classified as equity contracts, the Company allocates the transaction proceeds to the warrants and any other free-standing instruments issued in the transaction based on an allowable allocation method.

Clinical Trial Accruals

The Company’s preclinical and clinical trials are performed by third party contract research organizations ("CROs") and/or clinical investigators, and clinical supplies are manufactured by contract manufacturing organizations ("CMOs"). Invoicing from these third parties may be monthly based upon services performed or based upon milestones achieved. The Company accrues these expenses based upon its assessment of the status of each clinical trial and the work completed, and upon information obtained from the CROs and CMOs. The Company’s estimates are dependent upon the timeliness and accuracy of data provided by the CROs and CMOs regarding the status and cost of the studies, and may not match the actual services performed by the organizations. This could result in adjustments to the Company’s research and development expenses in future periods. To date the Company has had no significant adjustments.

Grants Receivable and Revenue

Salarius’ source of revenue has been from a grant received from CPRIT. Grant revenue is recognized when qualifying costs are incurred and there is reasonable assurance that conditions of the grant have been met. Cash received from grants in advance of incurring qualifying costs is recorded as deferred revenue and recognized as revenue when qualifying costs are incurred. Final reimbursement from the grant was received in the first quarter of 2023. The grant receivable balance at September 30, 2023 was zero

Research and Development Costs

Research and development costs consist of expenses incurred in performing research and development activities, including pre-clinical studies and clinical trials. Research and development costs include salaries and personnel-related costs, consulting fees, fees paid for contract research services, the costs of laboratory equipment and facilities, license fees and other external costs. Research and development costs are expensed when incurred.

Costs incurred in obtaining in-process research and development ("IPRD") that has no alternative future use are charged to research and development expense as acquired, and presented as investing activity cash outflows on the Statement of Cash Flow.

Equity-Based Compensation

Salarius measures equity-based compensation based on the grant date fair value of the awards and recognizes the associated expense in the financial statements over the requisite service period of the award, which is generally the vesting period.

The Company uses the Black-Scholes option valuation model to estimate the fair value of stock options granted to employees and directors. Assumptions utilized in these models including expected volatility calculated based on implied volatility from traded stocks of peer companies, dividend yield and risk-free interest rate. Additionally, forfeitures are accounted for in compensation cost as they occur. Restricted stock and restricted stock units granted to employees and directors are measured at fair value based upon the closing price of the Company's common stock on the grant date.

Table of Contents

Loss Per Share

Basic net loss per share is calculated by dividing the net loss applicable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Since the Company was in a loss position for all periods presented, diluted net loss per share is the same as basic net loss per share for all periods, as the inclusion of all potential common shares outstanding is anti-dilutive.

The number of anti-dilutive shares, consisting of common shares underlying (i) common stock options, (ii) stock purchase warrants, (iii) rights entitling holders to receive warrants to purchase the Company's common shares, and (iv) restricted stock units which have been excluded from the computation of diluted loss per share, was approximately 10,964,113 and 706,400 shares as of September 30, 2023 and 2022, respectively.

Income Taxes

Income taxes are recorded in accordance with FASB ASC Topic 740, Income Taxes ("ASC 740"), which provides for deferred taxes using an asset and liability approach. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial reporting and the tax reporting basis of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. The Company provides a valuation allowance against net deferred tax assets unless, based upon the available evidence, it is more likely than not that the deferred tax assets will be realized. The Company has evaluated available evidence and concluded that the Company may not realize the benefit of its deferred tax assets; therefore, a valuation allowance has been established for the full amount of the deferred tax assets.

The Company accounts for uncertain tax positions in accordance with the provisions of ASC 740. When uncertain tax positions exist, the Company recognizes the tax benefit of tax positions to the extent that the benefit will more likely than not be realized. The determination as to whether the tax benefit will more likely than not be realized is based upon the technical merits of the tax position as well as consideration of the available facts and circumstances. As of September 30, 2023 and December 31, 2022, the Company did not have any significant uncertain tax positions and no interest or penalties have been charged. The Company's practice is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company is subject to routine audits by taxing jurisdictions.

Acquisition and Strategic Collaboration Agreement - DeuteRx

On January 12, 2022, the Company entered into an Acquisition and Strategic Collaboration Agreement (the “ASCA”), with DeuteRx, LLC, a Delaware limited liability company (the “DeuteRx”), pursuant to which DeuteRx agreed to sell, and the Company agreed to purchase and assume from DeuteRx, all of DeuteRx’s rights, title, and interest in and to certain assets of DeuteRx, including SP-3164, DeuteRx’s intellectual property, information and data related to SP-3164, tangible materials or reagents related to SP-3164, goodwill, rights and claims, other than certain excluded assets (collectively, the “Purchased Assets”), all as more specifically set forth in the ASCA, and assume certain assumed liabilities, upon the terms and subject to the conditions set forth in the ASCA. The Aggregate purchase price paid under the ASCA was $2.0 million consisting of $1.5 million cash payment and the delivery of 40,000 shares of the Company's common stock, valued at $0.5 million. Total costs incurred in obtaining IPRD that has no alternative future use are charged to research and development expense as acquired, and presented as investing activity cash outflow on the Statement of Cash Flow. In addition, the Company agreed to pay to DeuteRx potential future milestone payments upon the occurrence of an applicable Milestone Event (as defined in the ASCA) and potential future royalty payments. A member of the Company’s Board of Directors also serves as a consultant to DeuteRx and is employed by an affiliate of DeuteRx.

Recently Adopted Accounting Standard

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires the measurement of all expected credit losses for financial assets including trade receivables held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Subsequent to the issuance of ASU 2016-13, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses. This ASU does not change the core principle of the guidance in ASU 2016-13, instead these amendments are intended to

Table of Contents

clarify and improve operability of certain topics included within the credit losses guidance. The FASB also subsequently issued ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Derivatives and Hedging (Topic 815), and Financial Instruments (Topic 825), which did not change the core principle of the guidance in ASU 2016-13, but clarified that expected recoveries of amounts previously written off and expected to be written off should be included in the valuation account and should not exceed amounts previously written off and expected to be written off. The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019 for public business entities, excluding smaller reporting companies. Early adoption is permitted. As a smaller reporting company, the guidance was effective for the Company on January 1, 2023. The adoption of this standard did not have a material impact to this Company's consolidated financial statements.

NOTE 3. GRANT RECEIVABLE FROM CPRIT

Grants receivable balances are $0.0 million and $1.6 million at September 30, 2023 and December 31, 2022. During the three and nine months ended September 30, 2023, the Company received $0 million and $1.5 million from CPRIT, respectively. Since inception, the Company has received approximately $16 million under the grant. The grant has been closed as of September 30, 2023.

NOTE 4. PREPAID EXPENSES AND OTHER CURRENT ASSETS

Prepaid expenses and other current assets at September 30, 2023 and December 31, 2022 consisted of the following:


	September 30, 2023		December 31, 2022
Prepaid clinical trial expenses	$	—	$	11,185
Insurance	660,077		624,612

Other prepaid and current assets	83,119		167,576
Total prepaid expenses and other current assets	$	743,196	$	803,373

Insurance is mainly comprised of prepaid directors' and officers' insurance. In July 2023, the Company financed its directors and officers' insurance premium with a short term note, the principal amount of which is approximately $0.6 million bearing interest at a rate of 7.87%. The note payable balance, which was included within Current Liabilities on the Condensed Consolidated Balance Sheet is $0.5 million at September 30, 2023.

NOTE 5. COMMITMENTS AND CONTINGENCIES

License Agreement with the University of Utah Research Foundation

In 2011, the Company entered into a license agreement with the University of Utah, under which the Company acquired an exclusive license to an epigenetic enzyme lysine specific demethylase 1 ("LSD1"). In exchange for the license, the Company issued 2% equity ownership in the Company on a fully diluted basis at the effective date of the agreement subject to certain adjustments specified in the agreement, such as granted revenue sharing rights on any resulting products or processes to commence on first commercial sale, and milestone payments based upon regulatory approval of any resulting product or process as well as on the second anniversary of first commercial sale.

Lease Agreement

The Company presently leases office space under operating lease agreements on a month-to-month basis.

NOTE 6. 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

Table of Contents

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. A fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last is considered unobservable, are used to measure fair value:

Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 - Significant unobservable inputs including Salarius’ own assumptions in determining fair value.

The Company believes the recorded values of its financial instruments, including cash and cash equivalents, accounts payable and note payable approximate their fair values due to the short-term nature of these instruments.

NOTE 7. STOCKHOLDERS' EQUITY

Common Stock - Issuances

During the nine months ended September 30, 2023, the Company sold 696,271 shares of common stock in an "at the market offering" ("ATM") under the Purchase Agreement, as defined below with gross proceeds of $1.7 million.

On May 11, 2023, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with an accredited investor (the “Investor”), pursuant to which the Company agreed to issue and sell to the Investor in a private placement (the “Offering”) (i) 330,000 shares (the “Shares”) of the Company’s common stock, par value $0.0001 per share (the “Common Stock”), (ii) pre-funded warrants (the “Pre-Funded Warrants”) to purchase up to 3,306,364 shares of Common Stock, (iii) Series A-1 warrants (the “Series A-1 Warrants”) to purchase up to 3,636,364 shares of Common Stock and (iv) Series A-2 warrants (the “Series A-2 Warrants”) and together with the Series A-1 Warrants, the “Common Stock Warrants,” and together with the Pre-Funded Warrants, the “Warrants”) to purchase up to 3,636,364 shares of Common Stock, at a purchase price of (a) $1.65 per Share and accompanying Common Stock Warrants and (b) $1.6499 per Pre-Funded Warrant and accompanying Common Stock Warrants. The aggregate gross proceeds from the Offering were approximately $6.0 million, exclusive of placement agent fees and expenses and other offering expenses. The Offering closed on May 16, 2023.

During the third quarter of 2023, the Company issued 586,364 shares of its Common Stock upon the exercise of Pre-Funded Warrants.

On January 12, 2022, the Company issued 40,000 shares of the common stock, valued at $0.5 million to purchase in-process research and development technology related to SP-3164, please refer to NOTE 2 for further discussion.

On April 22, 2022, the Company entered into a securities purchase agreement with certain institutional and accredited investors for the sale by the Company of approximately 373,577 shares of the Company’s common stock, par value $0.0001 per share (the “Common Stock”) at a purchase price of $6.25 per share. Concurrently, the Company also sold unregistered warrants exercisable for an aggregate of approximately 280,183 shares of Common Stock, which represents 75% of the shares of Common Stock sold, with an exercise price of $8.4975 per share. The transaction closed on April 26, 2022 with gross proceeds of $2.3 million before deducting certain fees due to the placement agent and other estimated transaction expenses.

Warrants Exercisable for Cash

The Company has five-year warrants outstanding that were issued in February 2020 and subsequently modified in December 2020 in connection with the issuance of additional inducement warrants. The warrants are exercisable at a price per share of $28.75. The inducement warrants expire on June 11, 2026, and are exercisable at a price per share of $29.55. The Company has 5.5 year warrants outstanding that were issued in April 2022, with an exercise

Table of Contents

price of $8.4975 per share. The warrants will be exercisable six months following the issuance date and will expire five and one-half years from the issuance date.

The Company's Series A-1 Warrants are exercisable for a period of five and one-half (5.5) years from the issuance date at an exercise price of $1.40 per share. Series A-2 Warrants are exercisable for a period of eighteen (18) months from the issuance date at an exercise price of $1.40 per share. Each Pre-Funded Warrant was sold in lieu of shares of Common Stock, are exercisable immediately upon issuance, have an exercise price of $0.0001 per share and expire when exercised in full.

In connection with the above mentioned Offering, the Company issued warrants to its exclusive placement agency H.C Wainwright & Co., LLC to purchase up to 254,454 shares of common stock at an exercise price per share of $2.0625 and a term of five and one-half (5.5) years.

As of September 30, 2023 and 2022, approximately 10,844,785 (2,720,000 are Pre-Funded Warrants) and 590,087 warrants remain outstanding, respectively.

The terms of the outstanding warrants require the Company, upon the consummation of any fundamental transaction to, among other obligations, cause any successor entity resulting from the fundamental transaction to assume the Company's obligations under the warrants and the associated transaction documents. In addition, holders of warrants are entitled to participate in any fundamental transaction on an as-converted or as-exercised basis, which could result in the holders of the Company's common stock receiving a lesser portion of the consideration from a fundamental transaction. The terms of the warrants could also impede the Company's ability to enter into certain transactions or obtain additional financing in the future.

NOTE 8. EQUITY-BASED COMPENSATION

Equity Incentive Plans

The Company has granted options to employees, directors, and consultants under the 2015 Equity Incentive Plan (the "2015 Plan"). The 2015 Plan provides for the grant of incentive stock options ("ISOs"), nonstatutory stock options, restricted stock awards, restricted stock units, stock appreciation rights, performance-based stock awards and other stock-based awards. Additionally, the 2015 Plan provides for the grant of performance-based cash awards. ISOs may be granted only to the Company's employees. All other awards may be granted to the Company's employees, including officers, and to non-employee directors and consultants. As of September 30, 2023, there were approximately 55,365 shares remaining available for grant awards under the 2015 Plan.

During the nine months ended September 30, 2023, the Company awarded 12,220 restricted stock units to its employees and 36,640 restricted stock awards to its officers and directors, pursuant to the plan described above. Both the restricted stock units and restricted stock awards are valued at the closing price $1.57 of the Company's common stock on the grant date, and generally vest over one to four years. Total fair value of the restricted stock awards and restricted stock units awarded during the nine - month period ended September 30, 2023 is $76,679.

During the nine-month periods ended September 30, 2023 and 2022, the Company awarded 0 and 51,360 stock options, to its employees and directors, pursuant to the plan described above. Stock options generally vest over one to four years and have a contractual term of ten years. Stock options are valued using the Black-Scholes option pricing model and compensation cost is recognized based on the resulting value over the service period. Expected volatilities utilized in the model are based on implied volatilities from traded stocks of peer companies. Similarly, the dividend yield is based on historical experience and the estimate of future dividend yields. The risk-free interest rate is derived from the U.S. Treasury yield curve in effect at the time of grant. The expected term of the options is based on the average period the stock options are expected to remain outstanding. The fair value of the option grants awarded during the nine - month period ended September 30, 2022 was $0.5 million, which has been estimated with the following assumptions on the grant date.

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

The following discussion and analysis should be read in conjunction with the unaudited financial information and the notes thereto included herein, as well as our audited financial statements and notes thereto contained in our Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on March 27, 2023. This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results and the timing of selected events could differ materially from those anticipated in these forward-looking statements as a result of several factors, including those set forth under "Part I - Item 1A - Risk Factors" discussed in our Annual Report on Form 10-K for the year ended December 31, 2022, in other subsequent filings with the SEC, and elsewhere in this Quarterly Report on Form 10-Q. These statements, like all statements in this report, speak only as of the date of this Quarterly Report on Form 10-Q (unless another date is indicated), and we undertake no obligation to update or revise these statements in light of future developments.

Recent Developments

On August 8, 2023, we announced that we retained Canaccord Genuity, LLC to lead a comprehensive review of strategic alternatives focusing on maximizing shareholder value, including but not limited to, an acquisition, merger, reverse merger, divestiture of assets, licensing, or other strategic transactions involving our company. However, there is no set timetable for this process and there can be no assurance that this process will result in us pursuing a transaction or that any transaction, if pursued, will be completed on attractive terms. If we are unable to complete a transaction, it may be necessary to seek other alternatives for restructuring and resolving our liabilities, including an orderly wind-down. We do not expect to disclose developments with respect to this process unless and until the evaluation of strategic alternatives has been completed or our Board of Directors has concluded that disclosure is appropriate or legally required.

In connection with the evaluation of strategic alternatives and in order to extend our resources, we have implemented a cost-savings plan that includes a reduction in workforce by over 50% of our positions, with remaining employees focusing primarily on limited general operating activities, completing the US Food and Drug Administration process to determine the clinical trial registration requirements for the seclidemstat Ewing sarcoma program and supporting the exploration of strategic alternatives

On September 5, 2023, we were notified (the “Notice”) by Nasdaq Stock Market, LLC (“Nasdaq”) that on September 1, 2023, the average closing price of our common stock (the “Common Stock”) over the prior 30 consecutive trading days had fallen below $1.00 per share, which is the minimum average closing price required to maintain listing on Nasdaq under Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Requirement”).

The Notice has no immediate effect on the listing or trading of our common stock. In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company has 180 calendar days to regain compliance with the Minimum Bid Requirement. To regain compliance, the closing bid price of our common stock must be at least $1.00 per share for a minimum of ten consecutive business days before March 4, 2024.

If we don't achieve compliance with the Minimum Bid Requirement during the initial 180 calendar day period, we have may be eligible for an additional 180 calendar day compliance period. To qualify, we would be required to meet the continued listing requirement for market value of publicly held shares and all other Nasdaq initial listing standards, with the exception of the bid price requirement, and would need to provide written notice of its intention to cure the deficiency during the second compliance period. However, if it appears to Nasdaq staff that we will not be able to cure the deficiency, or if we don't meet the other listing standards, Nasdaq could provide notice that our common stock will become subject to delisting. In the event the Company receives notice that its common stock is being delisted, Nasdaq rules permit us to appeal any delisting determination by the Nasdaq staff to a Hearings Panel.

There can be no assurance that we will be able to regain compliance with the Minimum Bid Requirement or maintain compliance with the other listing requirements.

We intend to actively monitor the closing bid price of its common stock and will evaluate available options to regain compliance with the Minimum Bid Requirement.

On October 13, 2023 we met with the FDA to identify activities necessary to seek US registration of SP-2577 as a treatment for Ewing sarcoma. We are in the process of implementing the initial activities that we believe is aligned with the FDA during the end of Phase 2 meeting process.

Table of Contents

Based on the advice received from the FDA and clinical data shared during the meeting process, we are preparing an amendment to the Ewing sarcoma clinical trial protocol and plan to submit that protocol in the fourth quarter of 2023.

Overview

We are a clinical-stage biopharmaceutical company focused on developing treatments for cancers with high, unmet medical need. Specifically, we are developing treatments for cancers caused by dysregulated gene expression, i.e., genes which are incorrectly turned on or off. We are developing two classes of drugs that address gene dysregulation: targeted protein degraders and inhibitors. Our technologies have the potential to work in both liquid and solid tumors. Our current pipeline includes the lead compounds: 1) SP-3164, a targeted protein degrader, and 2) seclidemstat (SP-2577), a targeted protein inhibitor.

We have no products approved for commercial sale and have not generated any revenue from product sales. We have never been profitable and have incurred operating losses in each year since inception. We had an accumulated deficit of $75.5 million as of September 30, 2023. Substantially all of our operating losses resulted from expenses incurred in connection with our research and development programs and from general and administrative costs associated with our operations. As of September 30, 2023, we had cash and cash equivalents of $7.6 million.

Our financial statements are prepared using Generally Accepted Accounting Principles in the United States of America (“GAAP”) applicable to a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. Our financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts and classification of liabilities should we be unable to continue as a going concern.

We believe that there is presently insufficient funding available to allow us to continue our current and planned clinical programs for a period exceeding 12 months from the date of this filing with the SEC.

The lack of revenue from product sales to date and recurring losses from operations since our inception raise substantial doubt as to our ability to continue as a going concern. We will continue to require substantial additional capital to continue our clinical development activities and will need such additional capital within the next several months to continue to fund our operations through the first quarter of 2024. The amount and timing of our future funding requirements will depend on many factors, including the results of our evaluation of strategic alternatives, the pace and results of our development, regulatory requirements and authorizations, and market conditions. Failure to raise capital as and when needed, on favorable terms or at all, would have a material negative impact on our financial condition and our ability to continue as a going concern.

We may attempt obtain additional capital through the sale of equity securities in one or more offerings or through issuances of debt instruments, which will likely cause significant dilution to our existing shareholders. We may also consider new collaborations or selectively partnering our technology. However, we cannot provide any assurance that we will be successful in accomplishing any of our plans to obtain additional capital or be able to do so on terms acceptable to us.

Although we are currently exploring various strategic alternatives, these strategic alternatives may not be successful in the next several months prior to our cash position getting to the point that we will need to pursue the winding down and dissolution of the Company. If we do not raise capital or successfully engage a strategic partner in the next several months, we will be forced to cease operations, liquidate our assets and possibly seek bankruptcy protection or engage in a similar process.

Program Development

Our goal has been to develop SP-3164 and SP-2577 for treatment of cancers while attempting to maximize return for investors. To achieve this goal, our strategy has consisted of a two-pronged approach: 1) speed-to-market by developing SP-3164 and SP-2577 in high unmet need indications and 2) expand the market by developing SP-3164 and SP-2577 in larger market indications.

SP-3164 – Targeted Protein Degradation

Table of Contents

SP-3164 is a next-generation cereblon-binding molecular glue. Molecular glues are small molecules that commandeer the body’s normal protein degradation processes by causing proteins to stick to one another thereby inducing selective degradation of cancer-causing proteins. Derived from avadomide, SP-3164 is engineered using DECS (deuterium-enabled chiral switching), a process that replaces hydrogen atoms with deuterium to stabilize the molecule’s active enantiomer, resulting in a novel molecular entity with the potential for increased efficacy and improved safety compared to the 1st generation compound. SP-3164 degrades transcription factors Ikaros (IKZF1) and Aiolos (IKZF3), resulting in both direct anti-cancer activity and immune-modulating properties. SP-3164 has potential to treat both hematologic and solid tumors. We have presented preclinical data of SP-3164 in hematological cancers at several scientific conferences highlighting its activity and differentiation. On July 11, 2023 we announced that the FDA had cleared our IND application to treat relapsed/refractory non-Hodgkin lymphoma patients with SP-3164.

Seclidemstat - Targeted Protein Inhibition

Our lead compound, seclidemstat (SP-2577), is a small molecule that inhibits the epigenetic enzyme lysine specific demethylase 1 (LSD1). LSD1 is an enzyme that removes mono- and di-methyl marks on histones (core protein of chromatin) to alter gene expression. LSD1’s enzymatic activity can cause genes to turn on or off and thereby affect the cell’s gene expression and overall activity. In addition, LSD1 can act via its scaffolding properties, independently of its enzymatic function, to alter gene expression and modulate cell fate. In healthy cells, LSD1 is necessary for stem cell maintenance and cell development processes. However, in several cancers LSD1 is highly expressed and acts aberrantly to incorrectly silence or activate genes leading to disease progression. High levels of LSD1 expression are often associated with aggressive cancer phenotypes and poor patient prognosis. Hence, development of targeted LSD1 inhibitors is of interest for the treatment of various cancers. SP-2577 uses a novel, reversible mechanism to effectively inhibit LSD1’s enzymatic and scaffolding properties and thereby treat and prevent cancer progression.

SP-2577 is being developed for both solid and liquid tumors. Our lead indication for SP-2577 is a devastating bone and soft-tissue cancer called Ewing sarcoma, which has a median age of diagnosis of 15. We are currently in a Phase 1/2 trial to treat relapsed/refractory Ewing sarcoma patients in combination with topotecan and cyclophosphamide.

In addition, as part of our market expansion strategy, in 2021 an Investigator Initiated Trial with the MD Anderson Cancer Center was initiated to study SP-2577 in combination with azacitidine for the treatment of patients with myelodysplastic syndromes (MDS) or chronic myelomonocytic leukemia (CMML). MDS and CMML can progress into Acute Myeloid Leukemia (AML), which the American Cancer Society estimates there were almost 20,000 new cases of AML in the US alone in 2020. In December of 2022 at the 64th American Society of Hematology (ASH) Annual Meeting and Exposition, investigators in the Department of Leukemia at the University of Texas MD Anderson Cancer Center presented clinical data on seclidemstat in patients with MDS and CMML. Data presented in a poster session included that as of October 2022, nine patients were enrolled with a median follow-up time of 3.9 months. Typically, overall survival is four to six months for patients after failing therapy with hypomethylating agents. In addition, of the eight evaluable patients, four (50%) had an objective response.

Research and Development Expenses

Research and development expenses decreased during the three months ended September 30, 2023 compared to the same period in 2022 primarily related to the cost-savings plan we implemented during the quarter.

We expect total research and development expenses and research and development expense for each of our research and development projects to decrease in the remainder of 2023 as compared to the prior year and into 2024 as compared to 2023 as we evaluate the development strategy for our product candidates, and explore and evaluate strategic alternatives.

Research and Development Expenses

Research and development expenses decreased during the nine months ended September 30, 2023 compared to the same period in 2022 primarily due to lower spending on SP-2577 which was offset by higher spending in SP-3164 in 2023 and we implemented a cost-savings plan during the third quarter of 2023. Our expenses for the

Liquidity and Capital Resources

Overview

Since inception, we have incurred operating losses and we anticipate that we will continue to incur losses for the foreseeable future. In August 2023, we commenced a process to explore and evaluate strategic alternatives to enhance shareholder value, which could result in a fundamental transaction as defined by the warrant agreement. The terms of the outstanding warrants require us, upon the consummation of any fundamental transaction to, among other obligations, cause any successor entity resulting from the fundamental transaction to assume our obligations under the warrants and the associated transaction documents. In addition, holders of warrants are entitled to participate in any fundamental transaction on an as-converted or as-exercised basis, which could result in the holders of our common stock receiving a lesser portion of the consideration from a fundamental transaction. The terms of the warrants could also impede our ability to enter into certain transactions or obtain additional financing in the future. In conjunction with our exploration of strategic alternatives, we are exploring opportunities to extend our resources.

As of September 30, 2023, we had $6.0 million of working capital and our cash and cash equivalents totaled $7.6 million, which were held in bank deposit accounts and a money market account. Our cash and cash equivalents balance decreased during the nine months ended September 30, 2023, primarily due to cash used in operating activities, partially offset by the cash received from financing activities. As recently announced, our cost savings plan extends our expected cash runway with a goal to provide us time to evaluate and implement strategic alternatives. We believe that our $$7.6 million in cash and cash equivalents on hand as of September 30, 2023, is sufficient to fund our current and restructured operations through the first quarter of 2024.

To provide the maximum degree of financial flexibility, and subject to our exploration of strategic alternatives, we may consider various potential opportunities to fund future operations and/or modulate liquidity needs, including: (i) seeking various strategic transactions, including a merger, licensing arrangement or sale that provide funding for our programs; (ii) entering into one or more collaborations to offset costs; (iii) reducing our expenditures on all business activities and/or restructuring our operations and reducing staff. If we are unable to execute on these activities, we may be forced to evaluate additional alternatives including a wind down of our operations.

We do not expect to generate any revenue from product sales unless and until we obtain regulatory approval for and commercialize our product candidate. At the same time, in connection with our exploration of strategic alternatives, we expect to continue to incur significant expenses and expect that our operating losses may fluctuate significantly from quarter-to-quarter and year-to-year.

Table of Contents

To date, we have secured capital from the sale of equity and grant revenue. Until we can generate a sufficient amount of revenue from our products, if ever, we intend, when required, to obtain additional capital through the sale of equity securities in one or more offerings or through issuances of debt instruments. We may also consider new collaborations or selectively partnering our technology. However, we cannot provide any assurance that we will be successful in accomplishing any of our plans to obtain additional capital or be able to do so on favorable terms acceptable to us. If we are unable to obtain additional financing, we may be required to significantly delay, scale back or discontinue the development or commercialization of our product candidate. Furthermore, we may be unable to complete a collaboration, or if we do, we may be forced to relinquish valuable future product rights.

Financing activities	6,809,061		1,987,375
Net decrease in cash and cash equivalents	$	(4,525,847)	$	(12,394,160)

Operating Activities

Net cash used in operating activities was $11.3 million in the current period, a decrease of approximately $1.5 million from the same period a year ago. The decrease is primarily due to significantly reduced operating expenses during the current quarter compared to the same period last year.

Investing Activities

Net cash used in investing activities was $1.5 million in the prior period, for the cash portion of the purchase price for the acquisition of in-process research and development technology SP-3164. There was no such transaction during the same period in 2023.

Financing Activities

Net cash provided by financing activities for the nine months ended September 30, 2023 was $6.8 million, compared to $2.0 million for the same period of the year 2022, resulting from the Company's sale of common shares under its ATM offering, common shares and Pre-Funded Warrants in a transaction that closed on May 16, 2023, partially offset by repayments to a note payable related to directors' and officers' insurance. Please refer to Notes 4 and 7 for more information.

Critical Accounting Policies and Estimates

Our management's discussion and analysis of our financial condition and results of operations is based on our condensed consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these condensed consolidated financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities as of the date of the condensed consolidated balance sheet and the reported amounts of expenses during the reporting period. In accordance with GAAP, we base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances at the time such estimates are made. Actual results may differ materially from our estimates and judgments under different assumptions or conditions. We periodically review our

Table of Contents

estimates in light of changes in circumstances, facts and experience. The effects of material revisions in estimates are reflected in our condensed consolidated financial statements prospectively from the date of the change in estimate.

There have been no material changes to our critical accounting policies from those described in "Management's Discussion and Analysis of Financial Condition and Results of Operations" included in our Annual Report on Form 10-K filed with SEC on March 27, 2023.

Readers should refer to our Annual Report on Form10-K filed with SEC on March 27, 2023, Note 2, Basis of Presentation and Significant Accounting Policies to the accompanying financial statements for descriptions of these policies and estimates.


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, and are not required to provide the information under this item.


Item 4.			Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of September 30, 2023. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of September 30, 2023, our principal executive officer and principal financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

During the three months ended September 30, 2023, there was no significant change in our internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION


Item 1.			Legal Proceedings

We are not a party to any material legal proceedings on the date of this report. We may from time to time become involved in legal proceedings arising in the ordinary course of business, and the resolution of any such claims could be material.


Item 1A.			Risk Factors

Investing in our stock involves a high degree of risk. You should carefully consider the following discussion of risk factors in its entirety. In addition to the other information set forth in this report, you should carefully consider the information under “Part I, Item 1A- Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on March 27, 2023.

We do not currently have sufficient working capital to fund our planned operations for the next twelve months and may not be able to continue as a going concern. There is uncertainty regarding our ability to maintain liquidity sufficient to operate our business effectively, which raises substantial doubt about our ability to continue as a going concern.

We currently do not have adequate financial resources to fund our forecasted operating costs for at least twelve months from the filing of this Quarterly Report on Form 10-Q. As of September 30, 2023, we had a cash and cash

Table of Contents

equivalents balance of approximately $7.6 million. As of September 30, 2023, we have incurred a accumulated deficit of $75.5 million. For the nine months ended September 30, 2023, we reported net losses of $11.7 million. As a result, our existing cash resources are not sufficient to meet our anticipated needs past the first quarter of 2024, even after taking into account our significantly reduced operations, and we would need to raise additional capital in the next several months to continue our operations past the end of the first quarter of 2024.

Our operating history and near-term forecast of incurring net losses and negative operating cash flows raise substantial doubt about our ability to continue as a going concern. We believe that our current cash and cash equivalents will be sufficient to fund our current planned operations through the first quarter of 2024 but that we will need to raise additional capital in the next several months in order to avoid a wind down and dissolution of the Company. Our auditors also included an explanatory paragraph in its report on our financial statements as of and for the year ended December 31, 2023 with respect to this uncertainty. Our ability to continue as a going concern is dependent upon our ability to obtain additional equity or debt financing, attain further operating efficiencies, reduce expenditures, and, ultimately, to generate revenue. Since inception, we have incurred net losses and negative cash flows from operations. We may not be successful or needed financing may not be available in the next several weeks. The resulting decline in the trading price of our common stock is further expected to negatively impact our ability to raise capital. Our existing cash and cash equivalents will not be sufficient to enable us to complete the clinical development and commercialization of our product candidates for any indications or to in license any other product candidates and develop them. If are unable to raise capital in the next several months or engage a strategic partner, we may be forced to cease operations and liquidate our assets and possibly seek bankruptcy protection or engage in a similar process. As such, we cannot conclude that such plans will be effectively implemented within one year after the date that the financial statements included in this Quarterly Report on Form 10-Q are filed with the SEC and there is uncertainty regarding our ability to maintain liquidity sufficient to operate our business effectively, which raises substantial doubt about our ability to continue as a going concern.

Our activities to evaluate and pursue strategic alternatives may not result in any definitive transaction or enhance shareholder value, and may create a distraction for our management and uncertainty that may adversely affect our operating results and business.

We have commenced a process to evaluate strategic alternatives in order to enhance stockholder value, including the possibility of an acquisition, merger, reverse merger, other business combination, sales of assets, licensing, or other strategic transactions involving the Company. We have engaged Canaccord Genuity, LLC as our financial advisor to assist us in this process. In connection with the evaluation of strategic alternatives, we are evaluating opportunities to extend our resources and have reduced our headcount by more than 50% of our positions. We expect to devote significant time and resources to identifying and evaluating strategic transactions and this process may create a distraction, uncertainty or the loss of business opportunities, which may adversely affect our operating results and business. We have incurred, and may in the future incur, significant costs associated with identifying, evaluating and negotiating potential strategic alternatives, such as legal, financial advisor and accounting fees and expenses and other related charges. We may also incur additional unanticipated expenses in connection with this process. A considerable portion of these costs will be incurred regardless of whether any such course of action is implemented or transaction is completed, decreasing cash available for use in our business. There can be no assurance that the process to evaluate strategic alternatives will result in agreements or transactions. The current market price of our common stock may reflect a market assumption that a transaction will occur, and a failure to complete a transaction could result in a negative investor perceptions and could cause a decline in the market price of our common stock, which could adversely affect our ability to access the equity and financial markets, as well as our ability to explore and enter into different strategic alternatives. Even if we negotiate a definitive agreement, there can be no certainty that any transaction will be completed, be on attractive terms, enhance stockholder value or deliver the anticipated benefits, and successful integration or execution of the strategic alternatives will be subject to additional risks. In addition, potential strategic transactions that require stockholder approval may not be approved by our stockholders. If we do not successfully consummate a strategic transaction, our board of directors may decide to pursue a dissolution and liquidation of our company. In such an event, the amount of cash available for distribution to our stockholders will depend heavily on the timing of such liquidation as well as the amount of cash that will need to be reserved for commitments and contingent liabilities.

If we do not successfully complete a strategic transaction, our board of directors may decide to pursue a dissolution and liquidation of our company. In such an event, the amount of cash available for distribution to our stockholders will depend heavily on the timing of such liquidation as well as the amount of cash that will need to be reserved for commitments and contingent liabilities.

There can be no guarantee that the process to identify a strategic transaction will result in a successfully completed transaction. If no transaction is completed, our board of directors may decide that it is in the best interest of our stockholders to dissolve our company and liquidate our assets. In that event, the amount of cash available for

Table of Contents

distribution to our stockholders will depend heavily on the timing of such decision and, ultimately, such liquidation, since the amount of cash available for distribution continues to decrease as we fund our operations and evaluate our strategic alternatives. In addition, if our board of directors were to approve and recommend, and our stockholders were to approve, a dissolution of our company, we would be required under Delaware corporate law to pay our outstanding obligations, as well as to make reasonable provision for contingent and unknown obligations, prior to making any distributions in liquidation to our stockholders. As a result of this requirement, a portion of our assets may need to be reserved pending the resolution of such obligations. In addition, we may be subject to litigation or other claims related to a dissolution and liquidation of our company. If a dissolution and liquidation were pursued, our board of directors, in consultation with its advisors, would need to evaluate these matters and make a determination about a reasonable amount to reserve. Accordingly, holders of our common stock could lose all or a significant portion of their investment in the event of a dissolution, liquidation or winding up of our company.

We could be delisted from Nasdaq, which would seriously harm the liquidity of our stock and our ability to raise capital.

Nasdaq requires listing issuers to comply with certain standards in order to remain listed on its exchange. If, for any reason, Nasdaq should delist our securities from trading on its exchange and we are unable to obtain listing on another reputable national securities exchange, a reduction in some or all of the following may occur, each of which could materially adversely affect our stockholders.

On September 5, 2023, we were notified (the “Notice”) by Nasdaq Stock Market, LLC (“Nasdaq”) that on September 1, 2023, the average closing price of our common stock over the prior 30 consecutive trading days had fallen below $1.00 per share, which is the minimum average closing price required to maintain listing on Nasdaq under Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Requirement”). Nasdaq’s notice had no immediate effect on the listing or trading of our common stock. Pursuant to Nasdaq Listing Rule 5810(c)(3)(A), we are provided an initial compliance period of 180 calendar days to regain compliance with the Minimum Bid Requirement. To regain compliance, the closing bid price of our common stock must meet or exceed $1.00 per share for a minimum of 10 consecutive business days prior to the deadline. If we do not achieve compliance with the Minimum Bid Requirement within 180 calendar days, we may be eligible for an additional 180 calendar days to regain compliance. To qualify, we would be required to meet the continued listing requirement for market value of publicly held shares and all other Nasdaq initial listing standards, with the exception of the Minimum Bid Requirement, and provide written notice of our intention to cure the minimum bid price deficiency during the second compliance period.

If the Nasdaq staff determines that we will not be able to cure the deficiency, or if we are otherwise not eligible for such additional compliance period, Nasdaq will provide notice that our common stock will be subject to delisting. In the event we receive notice that our common stock is being delisted, Nasdaq rules permit us to appeal any delisting determination by the Nasdaq staff. There can be no assurance that the Company will be able to regain compliance with the Minimum Bid Requirement or maintain compliance with the other listing requirements.

If, for any reason, Nasdaq were to delist our securities from trading on its exchange and we are unable to obtain listing on another reputable national securities exchange, a reduction in some or all of the following may occur, each of which could materially adversely affect our stockholders:

•liquidity and marketability of our common stock;

•our ability to obtain financing for the continuation of our operations;

•the number of institutional and general investors that will consider investing in our common stock;

•the number of market makers in our common stock;

•the availability of information concerning the trading prices and volume of our common stock; and

•the number of broker-dealers willing to execute trades in shares of our common stock

In addition, if we cease to be eligible to trade on Nasdaq, we may have to pursue trading on a less recognized or accepted market, such as the over the counter markets, our stock may be traded as a “penny stock” which would make transactions in our stock more difficult and cumbersome, and we may be unable to access capital on favorable terms or at all, as companies trading on alternative markets may be viewed as less attractive investments with higher associated risks, such that existing or prospective institutional investors may be less interested in, or prohibited from, investing in our common stock. This may also cause the market price of our common stock to further decline.

Table of Contents

Our cost savings plans and the associated headcount reductions may not result in anticipated savings, could result in total costs and expenses that are greater than expected and could disrupt our business.

On August 5, 2023, we approved a cost savings plan intended to preserve capital while we assess potential strategic alternatives. As of the filing of this Quarterly Report on Form 10-Q, the Company has recognized approximately $0.3 million separation cost during the third quarter of 2023. We may not realize, in full or in part, the anticipated benefits, savings and improvements in our cost structure from our cost savings efforts due to unforeseen difficulties, delays or unexpected costs. For example, we may incur unanticipated charges not currently contemplated as a result of the cost savings plans. If we are unable to realize the expected operational cost savings from the restructuring, our operating results and financial condition would be adversely affected.
