**Item 8.01. Other Events**

On July 10, 2025, Salarius Pharmaceuticals, Inc. ("Salarius") received notification from The Nasdaq Stock Market LLC ("Nasdaq") that the Nasdaq Hearings Panel (the "Hearings Panel") has granted Salarius an additional extension to regain compliance with Nasdaq Listing Rule 5550(b)(1) (the "Equity Standard") by late July 2025. Salarius must also regain compliance with Nasdaq Listing Rule 5550(a)(2) (the "Minimum Bid Price Requirement") by early August 2025.

As previously disclosed, on April 23, 2025, Salarius received written notice (the "Delisting Notice") from Nasdaq notifying Salarius that it was not in compliance with Nasdaq Listing Rule 5550(a)(2) because the closing bid price of Salarius' common stock for the last 30 consecutive business days was lower than the minimum bid price requirement of $1.00 per share. Normally, a company would have been afforded a 180-calendar day period to demonstrate compliance with the Minimum Bid Price Requirement. However, pursuant to Nasdaq Listing Rule 5810(c)(3)(A)(iv), Salarius was not eligible for any compliance period specified in Nasdaq Listing Rule 5810(c)(3)(A) because Salarius had effected a reverse stock split during the prior one-year period. In addition, as previously disclosed, on March 26, 2025, Salarius received a letter from Nasdaq notifying Salarius that, based on its Form 10-K for the year ended December 31, 2024, Salarius no longer complied with the Equity Standard. The letter indicated that Salarius had until May 12, 2025, to either regain compliance with the Equity Standard or submit a plan to Nasdaq to regain compliance with the Equity Standard (a "Compliance Plan"). However, pursuant to Nasdaq Listing Rule 5810(d)(2), Salarius' failure to comply with the Minimum Bid Price Requirement served as a separate and additional reason for delisting and, as such, the Delisting Notice indicated that Nasdaq would not entertain a Compliance Plan, and that it should address Salarius' noncompliance with the Equity Standard before the Hearings Panel if Salarius appealed Nasdaq's determination.

Salarius timely exercised its right to request a hearing, which stayed any suspension or delisting action pending the conclusion of the hearing process. On June 11, 2025, the Hearings Panel granted Salarius an extension to regain compliance with the Equity Standard and the Minimum Bid Price Requirement. The extension by the Hearings Panel is contingent on Salarius achieving scheduled milestones and notifying Nasdaq of such achievements. Such milestones initially consisted of regaining compliance with the Equity Standard by early July 2025, and regaining compliance with the Minimum Bid Price Requirement by early August 2025. The deadline for regaining compliance with the Equity Standard has now been extended to late July 2025.

**Salarius Pharmaceuticals Granted Additional Extension to Regain Compliance with Nasdaq's Stockholders' Equity Standard**

**HOUSTON (July 14, 2025) – Salarius Pharmaceuticals, Inc. (Nasdaq: SLRX)** (Salarius or the Company) announces that on July 10, 2025 the Company received notification from The Nasdaq Stock Market LLC (Nasdaq) of an additional extension to regain compliance with Nasdaq Listing Rule 5550(b)(1) (Equity Standard) by late July 2025. As previously disclosed, Salarius must also regain compliance with Nasdaq Listing Rule 5550(a)(2) (Minimum Bid Price Requirement) by early August 2025.

On April 23, 2025, Salarius was notified by Nasdaq that it was not in compliance with Nasdaq Listing Rule 5550(a)(2) because the closing bid price of Salarius' common stock for the prior 30 consecutive business days was lower than the minimum bid price requirement of $1.00 per share. On March 26, 2025, Nasdaq notified the Company that it no longer complied with the requirement under Nasdaq Listing Rule 5550(b)(1) to maintain a minimum of $2.5 million in stockholders' equity for continued listing on The Nasdaq Stock Market. On June 16, 2025, Salarius disclosed that the Nasdaq Hearings Panel had granted an extension contingent on Salarius achieving milestones that consist of regaining compliance with the Equity Standard by early July 2025, and regaining compliance with the Minimum Bid Price Requirement by early August 2025.

On January 13, 2025, Salarius announced entry into a definitive merger agreement for a business combination with Decoy Therapeutics, Inc. (Decoy), a privately held preclinical biopharmaceutical company engineering the next generation of peptide conjugate therapeutics. Under the definitive agreement announced on January 13, 2025, Decoy will merge with a wholly owned subsidiary of Salarius, subject to the closing conditions set forth in the agreement. The newly formed company will be named Decoy Therapeutics.

**About the Planned Merger** 

The proposed transaction, if consummated, is expected to facilitate multiple value-creating inflection points with Decoy's pipeline of peptide conjugate therapeutics engineered by its IMP<sup>3</sup>ACT platform, which allows for the rapid computational design and manufacturing of innovative peptide conjugate therapeutics. Decoy's product pipeline targets unmet needs in respiratory infectious diseases and gastroenterology (GI) oncology indications. In addition to advancing the development of Decoy's IMP<sup>3</sup>ACT platform, the combined company intends to incorporate Salarius' oral small molecule protein degrader SP-3164 into a highly targeted peptide-based proteolysis targeting chimeras (PROTACS) drug candidate.

The combined company will be led by Decoy's Co-founders, Chief Executive Officer Frederick "Rick" Pierce and Chief Scientific Officer Barbara Hibner, by Decoy's Chief Business Officer Peter Marschel, Chief Technology Officer Mike Lipp, by acting Chief Medical Officer and Scientific Advisory Board Chair Shahin Gharakhanian, M.D. and by Salarius' Chief Financial Officer Mark Rosenblum.

During the next 12 months, Decoy expects to advance its lead asset, a pan-coronavirus antiviral, to the filing of an Investigational New Drug (IND) application with the U.S. Food and Drug Administration (FDA), and to make progress with its other programs including a broad-acting antiviral against flu, COVID-19 and respiratory syncytial virus (RSV), and a peptide drug conjugate targeting GI cancers.

------

Also during this time, data may be reported from an investigator-initiated Phase 1/2 clinical study at MD Anderson Cancer Center evaluating Salarius' seclidemstat as a potential treatment for myelodysplastic syndrome and chronic myelomonocytic leukemia in patients with limited treatment options.

**About Decoy Therapeutics, Inc.** 

Decoy Therapeutics is a preclinical-stage biotechnology company that is leveraging machine learning and artificial intelligence tools alongside high-speed synthesis techniques to rapidly design, engineer and manufacture peptide conjugate drug candidates that target serious unmet medical needs. The company's initial pipeline is focused on respiratory viruses and GI cancers. Decoy has attracted financing from institutional investors as well as significant non-dilutive capital from the Massachusetts Life Sciences Seed Fund, the Google AI startup program and the NVIDIA Inception program among other sources. The company has also received QuickFire Challenge award funding provided by the Biomedical Advanced Research and Development Authority (BARDA) through BLUE KNIGHT™, a collaboration between Johnson & Johnson Innovation – JLABS and BARDA within the Administration for Strategic Preparedness and Response.

**About Salarius Pharmaceuticals** 

Salarius Pharmaceuticals is a clinical-stage biopharmaceutical company with two drug candidates for patients with cancer in need of new treatment options. Salarius' product portfolio includes seclidemstat, the company's lead candidate, which is being studied in an investigator-initiated Phase 1/2 clinical study in hematologic cancers underway at MD Anderson Cancer Center as a potential treatment for MDS) and chronic myelomonocytic leukemia (CMML) in patients with limited treatment options. SP-3164, the company's IND-stage second asset, is an oral small molecule protein degrader. Salarius previously received financial support for seclidemstat for the treatment of Ewing sarcoma from the National Pediatric Cancer Foundation and was a recipient of a Product Development Award from the Cancer Prevention and Research Institute of Texas (CPRIT). For more information, please visit www.salariuspharma.com.

**About the Proposed Transaction** 

Definitive agreements were executed with unanimous approvals by the Boards of Directors of Salarius and Decoy. The closing consideration will consist primarily of nonvoting preferred stock of Salarius, and it is expected that following closing and a post-closing stockholder vote to approve the conversion of the preferred shares into common stock, Decoy investors would own approximately 92.4% of the outstanding shares of the merged company and Salarius stockholders would own approximately 7.6% of the outstanding shares, in each case exclusive of any shares issued in any financing, including the qualifying financing(s) necessary to consummate the merger transaction. For further details on the transaction and conditions for closing of the merger, please refer to the Form 8-Ks Salarius filed with the U.S. Securities and Exchange Commission (SEC) on each of January 13, 2025, March 8, 2025 and June 11, 2025 at <u>www.sec.gov</u>.

**Non-Solicitation** 

This communication shall not constitute an offer to sell or the solicitation of an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. No public offer of securities in connection with the merger shall

be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act of 1933, as amended.
