Salarius meets Nasdaq equity standard; delisting risk if relapse

Rhea-AI Filing Summary

Salarius Pharmaceuticals (SLRX) announced it has regained compliance with Nasdaq’s minimum stockholders’ equity requirement under Listing Rule 5550(b)(1), as confirmed by a Nasdaq Hearings Panel on October 10, 2025.

If Salarius falls out of compliance with the equity standard during this monitoring period, Nasdaq staff will issue a delisting determination without allowing a compliance plan or cure period; Salarius would retain the right to request a hearing.

On October 13, 2025, the company issued a press release reiterating its compliance status.

Insights

Regulatory Compliance Analyst

Nasdaq compliance restored; a one-year monitor adds strict, binary downside if equity falls short again.

Salarius Pharmaceuticals, Inc. has regained compliance with Nasdaq Listing Rule 5550(b)(1), the Equity Standard, as of October 10, 2025. Nasdaq placed the company under a Mandatory Panel Monitor for one year starting that date. This indicates the listing has been preserved while subject to heightened oversight.

During the one-year monitor, if the Staff finds a new deficiency with the Equity Standard, the company will not receive time to submit a remediation plan or access the usual cure periods under Rule 5810(c)(3). Instead, Staff will issue a delisting determination, though the company can request a hearing with the Hearings Panel. This creates a stricter compliance regime with immediate procedural escalation upon any relapse.

What it means: listing risk is reduced today but becomes more binary over the next year. Key dependencies are maintaining stockholders’ equity at or above Nasdaq’s requirement throughout the monitor ending on or about October 10, 2026. Items to watch include any future disclosure affecting stockholders’ equity, and any Staff notices during the monitor. The company announced compliance in a October 13, 2025 press release (Exhibit 99.1).
