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").

Principles of Consolidation

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, ~~2020~~2021 included elsewhere in the Company's Annual Report on Form 10-K filed with the SEC on March ~~18, 2021.~~25, 2022. In the

~~Table of Contents~~

opinion of management, the unaudited interim financial statements reflect all the adjustments (consisting of normal

Table of Contents

recurring adjustments) necessary to state fairly the Company’s financial position as of ~~September~~June 30, ~~2021~~2022 and the results of operations for the three and ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 and ~~2020.~~2021. The interim results of operations are not necessarily indicative of the results that may occur for the full fiscal year. The December 31, ~~2020~~2021 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.

~~The Company maintains several bank accounts including an interest-bearing account for funds received from Cancer Prevention and Research Institution of Texas ("CPRIT").~~

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 for the three and ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 and ~~2020.~~2021.

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.

Impairment is the condition that exists when the carrying amount of goodwill exceeds its implied fair value. The first step in the impairment process is to determine the fair value of the reporting unit and then compare it to the carrying value, including goodwill. If the fair value exceeds the carrying value, no further action is required and no impairment charge is recognized. 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. Many of the events and circumstances evaluated in determining whether it is more likely than not that goodwill is impaired are outside of the Company’s control and could change in future periods. There was no impairment of goodwill during the three and ~~nine~~six months ended ~~September~~June 30, ~~2021~~2022 or ~~September~~June 30, ~~2020.~~2021.

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. Insurance is provided through the Federal Deposit Insurance Corporation (“FDIC”). 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

~~Table of Contents~~

the fair value of the warrant liability at the end of each reporting period for changes in fair value from the prior period

Table of Contents

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 Recognition

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.

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 technology ("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 the stock-based compensation and incentive units. 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.

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) unvested restricted stock, (iv) convertible preferred stock and (v) rights entitling holders to receive warrants to purchase the Company's common shares, which have been excluded from the computation of diluted loss per share, was ~~9,531,198~~17,807,776 and ~~10,075,278~~9,520,698 shares as of ~~September~~June 30, ~~2021~~2022 and ~~2020,~~2021, respectively.

Income Taxes

Table of Contents

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

~~Table of Contents~~

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~~June 30, ~~2021~~2022 and December 31, ~~2020,~~2021, 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.

~~Subsequent Events~~

~~The Company’s management reviewed all material events through the date that the financial statements were issued for subsequent event disclosure consideration.~~

~~Application of New Accounting Standards~~Pronouncements Not Yet Adopted

In ~~December 2019,~~June 2016, the FASB issued ASU No. ~~2019-12, Simplifying~~2016-13, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires the ~~Accounting~~measurement of all expected credit losses for ~~Income Taxes~~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 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 ~~740).~~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 eliminates certain exceptions for recognizing deferred taxes for investments, performing intra-period allocation and calculating income taxes in interim periods. This guidance also includes guidance to reduce complexity in certain areas, including recognizing deferred taxes for tax goodwill and allocating taxes to members of a consolidated group. ASU 2019-12 is effective for ~~annual~~fiscal years, and interim periods ~~in fiscal~~within those years, beginning after December 15, ~~2020.

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 based 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.

Cancer Prevention and Research Institute of Texas

In June 2016, the Company entered into a Cancer Research Grant Contract with CPRIT. Pursuant to the contract, CPRIT awarded the Company a grant of up to $18.7 million, further modified to $16.1 million, to fund the development of an LSD1 inhibitor. This is a 3-year grant award which originally expired on May 31, 2019. The grant now expires on May 31, 2022.

The Company will retain ownership over any intellectual property developed under the contract ("Project Result"). With respect to non-commercial use of any Project Result, the Company agreed to grant to CPRIT a nonexclusive, irrevocable, royalty-free, perpetual, worldwide license with right to sublicense any necessary additional intellectual property rights to exploit all Project Results by CPRIT, other governmental entities and agencies of the State of Texas, and private or independent institutions of higher education located in Texas, for education, research and other non-commercial purposes.

The Company is obligated to make revenue-sharing payments to CPRIT with respect to net sales of any product covered by the contract, up to a maximum repayment of a certain percentage of the aggregate amount paid to the Company by CPRIT under the CPRIT contract. The payments are determined as a percentage of net sales, which may be reduced if the Company is required to obtain a license from a third party to sell any such product. In addition, upon meeting the foregoing limitation on revenue-sharing payments, the Company agreed to make continued revenue-sharing payments to CPRIT of less than 1% of net sales.

Lease Agreement

The ~~CPRIT grant is subject~~Company presently leases office space under operating lease agreements on a month to funding conditions including a matching funds requirement where the Company will match 50% of funding from the CPRIT grant.

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 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.

~~Table of Contents~~

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.

Table of Contents

The following table sets forth a summary of changes in the fair value of Level 3 liabilities, the warrants issued in connection with the Company's merger with Flex Pharma in 2019 ("Flex Warrants"), which are measured at fair value on a recurring basis for the ~~three and nine~~six months ended ~~September~~June 30, ~~2021:~~2022:

NOTE 7. STOCKHOLDERS' EQUITY

~~Preferred Stock and~~ Common Stock

On ~~February 11, 2020,~~January 12, 2022, the Company, ~~completed~~entered into an Acquisition and Strategic Collaboration Agreement (the “ASCA”), with DeuteRx, LLC, a ~~public offering with total gross proceeds~~Delaware limited liability company (the “DeuteRx”), pursuant to which DeuteRx agreed to sell, and Company agreed to purchase and assume from DeuteRx, all of ~~approximately $11.0~~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 ~~which includes~~consisting of$1.5 million cash payment and the ~~full exercise~~delivery of 1 million shares of the ~~underwriter's over-allotment option~~Company's common stock, valued at $0.5 million.

A member of the Company’s Board of Directors also serves as a consultant to the Seller and is employed by an affiliate of the Seller.

On April 22, 2022, the Company entered into a securities purchase ~~an additional 1,252,173~~agreement with certain institutional and accredited investors for the sale by the Company of 9,339,436 shares ~~and warrants prior to deducting underwriting discounts and commissions and offering expenses payable by Salarius~~of the Company’s common stock, par value $0.0001 per share (the ~~“February 2020 Offering”~~“Common Stock”)~~. The February 2020 Offering was comprised of 7,101,307 Class A units, priced~~ at a ~~public offering~~purchase price of ~~$1.15~~$0.25 per ~~unit,~~share. Concurrently, the Company also sold unregistered warrants exercisable for an aggregate of 7,004,578 shares of Common Stock, which represents 75% of the shares of Common Stock sold, with ~~each unit consisting of 1 share of common stock and a five-year warrant to purchase 1 share of common stock at~~ an exercise price of $1.15 per share, and 1,246,519 Class B units, priced at a public offering price of $1.15 per unit, with each unit consisting of 1 share of Series A convertible preferred stock and a five-year warrant to purchase 1 share of common stock with and exercise price of $1.15$0.3399 per share. ~~A total~~The transaction closed on April 26, 2022 with gross proceeds of 8,353,480 shares of common stock, 1,246,519 shares of Series A convertible preferred stock, and warrants to purchase up to 9,599,999 shares of common stock were issued in the offering, including the full exercise of the over-allotment option. The exercise price of the warrants are fixed and do not contain any variable pricing features or any price based anti-dilutive features. All Series A preferred stock was converted to common stock prior to December 31, 2020.

As discussed above, in connection with the February 2020 Offering, the Company issued five-year warrants to purchase 1 share of common stock at an exercise price of $1.15 per share (each a "warrant").

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, ~~2020,~~2021, filed with the SEC on March ~~18, 2021.~~25, 2022. 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, ~~2020,~~2021, 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.

Overview

We are a clinical-stage biopharmaceutical company focused on developing ~~effective~~ treatments for cancers with high, unmet medical ~~need.~~ need. Specifically, we are developing treatments for cancers caused by dysregulated gene expression, i.e., genes ~~that~~which are incorrectly turned on or off. The field concerned with gene expression regulation is called ‘epigenetics’. As cancers are often diseases driven by gene dysregulation, epigenetics is an area of interest for cancer treatment. Our lead epigenetic based technology, seclidemstat ("SP-2577"), may treat cancers by restoring correct gene expression.

In 2011, Salarius licensed SP-2577 and related compounds from the University of Utah Research Foundation. SP-2577 is a small molecule that inhibits the epigenetic enzyme lysine specific demethylase 1 (“LSD1”). 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 (protein-protein interactions), independently of its enzymatic function, to alter gene expression and modulate cell fate. In healthy cells, LSD1 is necessary for stem cell maintenance and normal cell development processes. However, in several cancers LSD1 is highly expressed and acts 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. To effectively develop SP-2577, we are pursuing a speed-to-market and market expansion strategy.

~~As part of our speed-to-market strategy, we are initially focused on developing SP-2577 for the treatment of sarcomas with high unmet needs.~~ We are ~~investigating SP-2577 for the treatment~~developing two classes of ~~several advanced sarcoma subtypes, including Ewing sarcoma, myxoid liposarcoma,~~drugs that address gene dysregulation: epigenetic inhibitors and other sarcomas that share similar biology, i.e. FET-rearranged sarcomas. The described sarcomas are all driven by a chromosomal translocation involving a FET-gene family member (EWS, FUS, or TAF15). The translocation results in an FET-rearranged fusion oncoprotein. SP-2577’s target, LSD1, has been shown to associate with FET-rearranged fusion oncoproteins to help promote tumor growth.

We believe SP-2577 disrupts LSD1 from associating with FET-rearranged fusion oncoproteins and therefore leads to inhibition of the fusion oncoprotein’s cancer promoting activity. As a result, SP-2577 hastargeted protein degraders. Our technologies have the potential to ~~treat FET-rearranged sarcomas by reversing cancer promoting gene expression~~work in both liquid and ~~thereby possibly preventing tumor growth~~solid tumors. Our current pipeline consists of: 1) seclidemstat (SP-2577), a targeted LSD1 protein inhibitor, 2) SP-3164, a targeted protein degrader, and ~~causing cancer cell death. Preclinical studies of SP-2577~~3) a second generation LSD1 inhibitor program in several FET-rearranged sarcoma cell lines including Ewing sarcoma, myxoid liposarcoma, clear cell sarcoma, and desmoplastic small round cell tumors demonstrated that SP-2577 was effective in inhibiting cell proliferation and viability. Additionally, in certain Ewing sarcoma animal models, SP-2577 showed a significant tumor reduction as well as a significant survival benefit compared to untreated animals. Our ongoing Phase 1/2 clinical trial was designed as a single agent dose escalation followed by a dose expansion study in Ewing sarcoma. As a result, given the described preclinical data in FET-rearranged sarcomas and clinical data in FET-rearranged sarcoma patients from our Advanced Solid Tumor (AST) trial, in 2021 we expanded the trial to study SP-2577 in non-Ewing FET-rearranged sarcomas. The amended ongoing dose expansion portion of the trial is studying SP-2577 in combination with a common chemotherapeutic regimen, topotecan and cyclophosphamide ("TC") in Ewing sarcoma patients and single agent SP-2577 in myxoid liposarcoma and other FET-rearranged sarcoma patients. The dose expansion portion can enroll up to 30 relapsed or refractory Ewing sarcoma patients and up to 30 relapsed or refractory FET-rearranged patients (of which up to 15 will be myxoid liposarcoma). In Ewing sarcoma patients, the trial will assess the safety and tolerability of SP-2577 and TC and study preliminary efficacy of the regimen. In myxoid liposarcoma and other FET-rearranged sarcoma patients, the trial is studying single-agent SP-2577 safety, tolerability, and preliminary efficacy. drug discovery.

~~Table of Contents~~

As LSD1 can interact with over 60 regulatory proteins other than FET-fusion oncoproteins, we believe that LSD1 may also play a critical role in progression of various other cancer types. Preliminary efficacy data from our Phase 1/2 AST trial supports this notion and work is ongoing to identify large market solid tumor indications with the highest potential for SP-2577 success. Continued progress in this area will support the market expansion portion of our strategy.

In addition to solid tumors, SP-2577 has shown promising preclinical activity in hematologic cancers. We recently announced the initiation of an Investigator Initiated Trial studying SP-2577 in combination with azacitidine for the treatment of patients with myelodysplastic syndromes or chronic myelomonocytic leukemia. Myelodysplastic syndromes can progress into Acute Myeloid Leukemia (AML) and data from our ongoing trial will inform development of SP-2577 in hematologic cancers (also referred to as “liquid tumors" or "blood cancer”), including AML.~~The American Cancer Society estimates there were almost 20,000 new cases of AML in the US alone in 2020.~~

Recent data from “LSD1 Ablation Stimulates Anti-tumor Immunity and Enables Checkpoint Blockade” by W. Sheng, et al. and “Inhibition of Histone Lysine-specific Demethylase 1 Elicits Breast Tumor Immunity and Enhances Antitumor Efficacy of Immune Checkpoint Blockade” by Y. Qin, et al. suggests that LSD1 plays a role in tumor immune activity and can sensitize tumors to checkpoint inhibitors. These works have sparked interest in combining LSD1 inhibitors with checkpoint inhibitors. We are conducting preclinical work with SP-2577 in this area.

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 ~~$28.1~~$43.0 million as of ~~September~~June 30, ~~2021.~~2022. 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 June 30, 2022, we had cash and cash equivalents of $22.6 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 expect to continue to incur significant expenses and increasing operating losses for at least the next several years as we initiate and continue the clinical development of, and seek regulatory approval for, our product candidate, add personnel necessary to continue to operate as a public company, and work to develop an advanced clinical pipeline of product candidates. We expect that our operating losses will fluctuate significantly from quarter-to-quarter and year-to-year due to timing of clinical development programs and efforts to achieve regulatory approval.

AsThe lack of ~~September 30, 2021, the Cancer Prevention~~revenue from product sales to date and ~~Research Institution of Texas ("CPRIT") fund matching requirements had been fully met and we have expended all current available funds under the grant.

Seclidemstat - Targeted Protein Inhibition

Table of Contents

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. Based on SP-2577’s proposed mechanism of action, preclinical data, and clinical data from our earlier Advanced Solid Tumor trial, we expanded the Ewing sarcoma dose expansion trial to include a cohort of Ewing-related sarcomas (also referred to as FET-translocated sarcomas). Ewing sarcoma and FET-translocated sarcomas are rare cancers that may provide a speed-to-market development approach. In addition, as part of our market expansion strategy, in 2021 we initiated an Investigator Initiated Trial with the MD Anderson Cancer Center that is studying 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.

SP-3164 – Targeted Protein Degradation

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 IKZF1 and IKZF3, along with other proteins, resulting in both direct anti-cancer activity and immune-modulating properties.SP-3164 has potential to treat both hematologic and solid tumors and is currently in IND-enabling studies.

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

Special Note About Coronavirus (COVID-19)

The ongoing COVID-19 coronavirus pandemic (the “Pandemic”) has had a significant effect on the United States, global economies, and business worldwide. While we have thus far experienced minimal disruptions from the Pandemic, the duration and full extent to which the Pandemic impacts our business and financial condition depends on future developments that are highly uncertain, subject to change and are difficult to predict, including new information that may emerge concerning the Pandemic, and may cause intermittent or prolonged periods of interruptions to our clinical operations. We are continuously monitoring the Pandemic and its potential effect on our financial position, results of operations and cash flows. This uncertainty could have an impact in future periods on certain estimates used in the preparation of our periodic financial results. Uncertainty around the extent and length of time of the Pandemic, and any future related financial impact cannot be reasonably estimated at this time.

Grant Revenue

Grant revenue, which was derived solely from the CPRIT grant, was $0 for six months ended June 30, 2022 resulting from the completion of CPRIT available funding under the grant during the second quarter of 2021. We have reached the maximum amount of the eligible spending that can be reimbursed from CPRIT.

Research and Development Expenses

Research and development expenses increased during the six months ended June 30, 2022 compared to the same periods in 2021 resulting primarily from the purchase of SP-3164 as an in-process research and development technology and continued spending on SP-3164 drug development. Cost associated with SP-2577 is slightly higher compared to the prior year, mainly driven by higher outsourced research and development costs, personnel costs and clinical trial costs, offset by lower manufacturing cost.

General and Administrative Expenses

General and administrative expenses increased to $3.5 million during the six months ended June 30, 2022 from $2.9 million for the six months ended June 30, 2021 due to higher personnel costs and public company cost.

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.

As of June 30, 2022, we had $20.2 million of working capital and our cash and cash equivalents totaled $22.6 million, which were held in bank deposit accounts and a money market account. Our cash and cash equivalents balance decreased during the six months ended June 30, 2022, primarily due to cash used in operating and investing activities, offsetting by the cash received from financing activities.

Table of Contents

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, we expect to continue to incur significant expenses and increasing operating losses for at least the next several years as we initiate and continue the clinical development of, and seek regulatory approval for, our product candidate, add personnel necessary to continue to operate as a public company, and work to develop an advanced clinical pipeline of product candidates. We expect that our operating losses will fluctuate significantly from quarter-to-quarter and year-to-year due to timing of clinical development programs and efforts to achieve regulatory approval.

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 ~~or on terms~~ acceptable to us.

~~Table of Contents~~

~~Recent Developments~~

On July 2, 2021, the Company filed a prospectus supplement with the SEC to register the offering and sale of our common stock pursuant to the terms of that certain At the Market Offering Agreement (the “Sales Agreement”) between the Company and Ladenburg Thalmann & Co. Inc. (“Ladenburg”), dated as of on February 5, 2021, having an aggregate offering price of up to $25.0 million (the “Additional Shares”). We had previously filed a prospectus supplement with the SEC registering the offering and sale of our common stock under the Sales Agreement having an aggregate offering price of up to $6.3 million (together with the Additional Shares, the “ATM Shares”). Under the Sales Agreement the Company is able to issue and sell, from time to time, shares of its common stock with Ladenburg acting as an agent for such sales. Sales of the ATM Shares may be made by any method permitted by law deemed to be an “at the market offering” as defined in Rule 415(a)(4) of the Securities Act of 1933, as amended, including, without limitation, sales made directly on or through the NASDAQ Capital Market. During the three month period ending September 30, 2021 the Company sold 393,741 ATM shares for aggregate net proceeds of $0.4 million. In aggregate, during the nine months ended September 30, 2021, we issued 3,214,234 shares under the Sales Agreement for net proceeds of $6.7 million.

~~Special Note About Coronavirus (COVID-19)~~

The COVID-19 pandemic is significantly affecting the United States, global economies, and businesses worldwide. While the potential magnitude and duration of the economic and social impact of the COVID-19 pandemic is difficult to assess or predict, the impact on the global financial markets may, in the future, reduce our ability to access capital, which could negatively impact our short-term and long-term liquidity. At this time we are experiencing minimal disruption to our clinical trials. However, our ongoing Phase 1/2 Ewing sarcoma clinical trial and Phase 1/2 AST clinical trial may encounter delays in enrolling new patients due to concerns or healthcare resource constraints because of the COVID-19 pandemic. In addition, although at this time we have experienced no disruptions to manufacturing capabilities, certain aspects of our supply chain may be disrupted as certain of our third party suppliers and manufacturers have paused their operations in response to the COVID-19 pandemic or have otherwise encountered delays in providing supplies and services. The COVID-19 pandemic could also have a material and negative impact on our liquidity, capital resources (including our ability to secure additional financing if and when needed), our business and operations, and our workforce, as well as those of the third parties with which we do business or upon which we rely. While the situation is fluid and we do not yet know the full extent of potential delays or impacts on us or on healthcare systems or the global economy in general, we have worked to adapt to the unexpected and challenging circumstances resulting from the COVID-19 pandemic. However, we may experience disruptions in the future that have and could further adversely impact our business operations as well as our preclinical studies and clinical trials.

~~Grant Revenue~~

Grant revenue, which was derived solely from the CPRIT grant, was $0 for the three month period ended September 30, 2021 resulting from the completion of CPRIT available funding under the grant during the second quarter of 2021. We have reached the maximum amount of the eligible spending that can be reimbursed from CPRIT.

~~Research and Development Expenses~~

Research and development expenses increased during both the current period and nine months ended September 30, 2021 compared to the same periods in 2020 resulting from significantly higher personnel costs, clinical trial costs~~and higher laboratory costs resulting from increased non clinical efforts, all of which more than offset lower manufacturing and process development costs.~~

~~General and Administrative Expenses~~

General and administrative expenses increased during the current three month period compared to the same period a year ago resulting from higher personnel costs and increased professional fees. For the nine months ended September 30, 2021 general and administrative costs were lower than the same period a year ago resulting from lower overall personnel costs (severance costs in 2020 that did not repeat in the current period), and lower professional fees.

~~Government Grant Other Income~~

On July 12, 2021, the Small Business Administration (SBA) authorized full forgiveness of $0.2 million for the Company's Paycheck Protection Program (PPP) Loan. The Company had previously recognized this as government grants and other income during the nine months ended September 30, 2020.

~~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. To date, we have secured capital from the sale of equity and grant revenue.

~~Table of Contents~~

~~our ongoing research and development and manufacturing activities, particularly as we advance our product candidates to later stages of development.~~

Until we can generate a sufficient amount of revenue from our products, if ever, we expect to finance future cash needs through public or private equity or debt offerings or other collaborations. Additional capital may not be available on reasonable terms, if at all. If we are unable to ~~raise~~obtain additional ~~capital in sufficient amounts or on terms acceptable to us,~~financing, we may ~~have~~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.

We believe that, based on our current operating plan, our current unrestricted cash and cash and cash equivalent balances will be sufficient to fund our operations through the completion of our current clinical trials in 2022 and beyond.

As of September 30, 2021, we had $33.6 million of working capital and our cash and cash equivalents totaled $31.9 million, which were held in bank deposit accounts and a money market account. Our cash and cash equivalents balance increased during the nine months ended September 30, 2021, primarily due to sales of our common stock in our public offering which closed on March 8, 2021 and receipt of $2.7 million as a payment of~~our CPRIT remaining receivable.~~

~~Risks Related~~We have incurred losses since our inception, have a limited operating history on which to ~~Our Business and Our Industry~~

~~The COVID-19 pandemic could adversely affect~~assess our business, ~~results of operations,~~ and ~~financial condition.~~

To date, the COVID-19 pandemic has negatively impacted the global economy and the magnitude, severity, and duration of this impact is unclear and difficult to assess. In addition, certain areas, including Texas whereanticipate that we are headquartered, have recently experienced a resurgence of COVID-19 cases. We have worked to adapt to the unexpected and challenging circumstances resulting from the COVID-19 pandemic. At this time we have experiencing minimal disruption to our clinical trials during the nine months ended September 30, 2021. While both our Ewing sarcoma clinical study and our Advanced Solid Tumor clinical study are active., either or both may encounter delays in enrolling new patients due to concerns or healthcare resource constraints because of the COVID-19 pandemic. We plan to release clinical data from both studies, as previously disclosed, during 2021 and 2022.~~However, the situation with respect to the COVID-19 pandemic and its impact changes daily and is difficult to predict.~~

In addition, although at this time we have experienced no disruptions to manufacturing capabilities, certain aspects of our supply chain may be disrupted as certain of our third party suppliers and manufacturers have paused their operations in response to the COVID-19 pandemic or have otherwise encountered delays in providing supplies and services.

To combat the spread of COVID-19, the United States and other locations in which we operate have imposed measures such as quarantines and “shelter-in-place” orders that are restricting business operations and travel and requiring individuals to work from home (“WFH”), which has impacted all aspects of our business as well as those of the third-parties we rely upon for certain supplies and services.The continuation of WFH and other restrictions for an extended period of time may negatively impact our productivity, research and development, operations, preclinical studies and clinical trials, business and financial results. Among other things, the COVID-19 pandemic may result in:

•~~a global economic recession or depression that could significantly and negatively impact our business or those of third parties upon which we rely for services and supplies;~~

•~~constraints on our ability to conduct our operations and our preclinical studies and clinical trials;~~

•~~delays in our ability to extend the term of the CPRIT grant;~~

•~~reduced productivity in our business operations, research and development, marketing, and other activities;~~

•~~disruptions to our third-party manufacturers and suppliers;~~

•~~increased costs resulting from WFH or from our efforts to mitigate the impact of COVID-19; and~~

•~~reduced access to financing to fund our operations due to a deterioration of credit and financial markets.~~

Wewill continue to monitor the situation and the continued disruption of the COVID-19 pandemic and its effects on the worldwide economy could negatively and materially impact our operating and financial operating results. The resumption of normal business operations may be delayed and a resurgence of COVID-19 could occur resulting in continued disruption to us or to the third parties with which we do business. As a result, the effects of the COVID-19 pandemic could have a material adverse impact on our business, results of operations, and financial conditionincur significant losses for the ~~remainder~~foreseeable future which together with our limited working capital, and lack of ~~2021~~revenue from product sales, raises substantial doubt about our financial viability and ~~beyond.~~as to whether we will be able to continue as a going concern.

Table of Contents

~~Risks Related to Salarius’ Financial Condition and Capital Requirements~~

We will continue to require substantial additional capital to fund our clinical activities and operations and the impact of the COVID-19 pandemic on the financial markets will likely negatively impact our ability to raise additional financing.

~~Table of Contents~~

We are a clinical development-stage biopharmaceutical company with a limited operating history. 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. Our net losses were ~~$7.4~~$12.8 million for the year ended December 31, ~~2020,~~2021, and we have incurred a net loss of ~~$3.7~~$4.7 million and ~~$8.7~~$10.8 million for the three ~~and nine~~ months ended ~~September~~June 30, ~~2021,~~2022 and six months ended June 30, 2022, respectively. We have prepared our financial statements on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or amounts of liabilities that might be necessary should we be unable to continue in existence.

We will continue to require substantial additional capital to continue our clinical development and potential commercialization activities. Accordingly, we will need to raise substantial additional capital to continue to fund our operations. The development of our product ~~candidate~~candidates and funding our operations have been funded through sales of equity and funds received from CPRIT. The amount and timing of our future funding requirements will depend on many factors, including but not limited to the pace and results of our clinical development efforts, as well as our ability to access the funding remaining available under the CPRIT grant. Further, the global economic downturn may impair our ability to obtain additional financing through other means, such as debt financing. There can be no assurance we will be able to secure additional financing on favorable terms to us, or at all. Further any debt financing may contain restrictive covenants which limit our operating flexibility and any equity financing will likely result in additional and possibly significant dilution to existing stockholders. Failure to raise sufficient capital, as and when needed or on commercially reasonable terms, would have a significant and negative impact on our financial condition and our ability to develop our product candidate.

We rely on funding from CPRIT and failure to receive additional funds may harm our business.

During the course of the development of our product candidate, we have been funded through the sale of equity and the funding we received from the CPRIT grant. The CPRIT agreement was awarded in June 2016 and originally provided for a three-year grant award of up to $18.7 million, further modified to $16.1 million, to fund the development of the LSD-1 inhibitor. We have received ~~$14~~$14.5 million since inception of the grant. The term of the CPRIT agreement was extended through ~~May 31,~~November 30, 2022. We currently have a ~~$2.1~~$1.6 million receivable due from CPRIT on our ~~September~~June 30, ~~2021~~2022 balance sheet. If CPRIT terminates our agreement prior to the expiration due to an event of default or if we terminate the agreement, CPRIT may require us to repay some or all of the disbursed grant. Although we may apply for government contracts and grants in the future, we may not be successful in obtaining additional grants for any product candidates or programs.

Risks Related to Our Common Stock

If we ~~are unable~~fail to comply with the continued listing standards of Nasdaq, our common stock may be delisted from Nasdaq. This in turn could result in significantly reduced trading liquidity, reduced trading volumes, and loss of research analyst coverage, among other consequences. These in turn could result in a further decline in the market price of common stock and would have a material adverse effect on our company.

On November 16, 2021, we received a notice from Nasdaq, or the Notice, that on November 15, 2021, 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 ~~of our securities~~ on Nasdaq under Nasdaq Listing Rule 5450(a)(1), or the ~~Nasdaq Capital Market or another reputable stock exchange, it may be more difficult for our stockholders~~Minimum Bid Requirement. The Notice indicated that, to ~~sell their securities.~~

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 ofregain compliance, the ~~following may occur, each of which could materially adversely affect our stockholders.~~

~~For example, if at any time the~~closing bid price of our common stock ~~closes~~must be at ~~below~~least $1.00 per share for ~~more than 30~~a minimum of ten consecutive ~~trading~~business days before May 16, 2022.

On May 17, 2022, we ~~may be subject~~received a letter from Nasdaq notifying us that we have been granted an additional 180-day period, or until November 14, 2022, to ~~delisting from~~regain compliance with the Minimum Bid Price Requirement. The new compliance period is an extension of the initial compliance period provided for in the Notice. Nasdaq’s determination was based on our meeting the continued listing requirement for market value of publicly held shares and all other applicable requirements for initial listing on the Nasdaq Capital ~~Market. If we receive a delisting~~Market, with the exception of the Minimum Bid Price Requirement, and our written notice ~~we would have 180 calendar days~~of our intention to ~~regain compliance (subject to any additional 180-day~~cure the deficiency during the second compliance period ~~which may be available~~by effecting a reverse stock split, if necessary.

Table of Contents

We intend to ~~us), which would mean having a~~actively monitor the closing bid price ~~above the minimum~~ of ~~$1.00 for at least 10 consecutive days in the 180-day period. During this 180-day period, we would anticipate reviewing~~ our common stock and will evaluate available options to regain compliance with the ~~minimum bid requirements, including conducting~~Minimum Bid Requirement, such as implementing a reverse stock split. At our 2022 Annual Meeting of Stockholders, our stockholders approved an amendment to our Certificate of Incorporation to effect a reverse stock split of all of our outstanding shares of common stock by one of several fixed ratios between 1-for-5 and 1-for-30, with the final decision of whether to proceed with the reverse stock split, the effective time of the reverse stock split, and the exact ratio of the reverse stock split to be determined by our board of directors, in its sole discretion and without further action by our stockholders. In the event a reverse stock split is implemented, there is no assurance that the reverse stock split will not cause an actual decline in the value of our outstanding common stock. The liquidity of the shares of our common stock may be affected adversely by the reverse stock split given the reduced number of shares that will be outstanding following the reverse stock split, especially if the market price of our common stock does not increase as a result of the reverse stock split. In addition, the reverse stock split may increase the number of stockholders who own odd lots (less than 100 shares) of our common stock, creating the potential for such stockholders to experience an increase in the cost of selling their shares and greater difficulty effecting such sales.

To the extent that we are unable to resolve any listing deficiency, including if a reverse stock split it is unsuccessful in sufficiently raising the market price of our common stock, there is a risk that our common stock may be delisted from Nasdaq, which would adversely impact liquidity of our common stock and potentially result in even lower bid prices for our common stock and potentially result in even lower bid prices for our common stock. ~~On November 1, 2021,~~If for any reasons, Nasdaq should delist our common stock, and if our common stock is not then eligible for quotation on another market or exchange, trading of shares of our common stock could be conducted in the ~~closing~~over-the-counter markets. In such event, a reduction in some or all of the following may occur, each of which could materially and adversely affect our stockholders:

a.the liquidity of our common stock;

b.the market price of our common stock;

c.our ability to obtain financing for the continuation of our operations;

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

e.the number of market makers in our common stock;

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

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

The occurrence of any of these events could result in a further decline in the market price of common stock ~~was $0.85 per share.~~and could have a material adverse effect on us.
