Profusa, Inc. Receives Nasdaq Notice After 1-for-4 Reverse Split

What Happened

• Profusa, Inc. (PFSA) filed an 8‑K on Aug 31, 2026 reporting that Nasdaq’s Listing Qualifications Department sent a Determination Letter after the company’s recent 1‑for‑4 reverse stock split. Nasdaq noted the company had fewer than the 500,000 publicly held shares required under Nasdaq Listing Rule 5550(a)(4) immediately following the split.
• Nasdaq also stated that based on the company’s correspondence on Aug 21, 2026, Nasdaq determined Profusa complied with the publicly held shares requirement as of Aug 21, 2026. There is no immediate effect on the listing or trading of Profusa’s common stock, which continues to trade on the Nasdaq Global Market under the symbol “PFSA.”

Key Details

• Event reported on Form 8‑K filed Aug 31, 2026 (Item 3.01) following a 1‑for‑4 reverse stock split.
• Nasdaq Listing Rule involved: 5550(a)(4) — 500,000 publicly held shares requirement.
• Nasdaq found the company compliant as of Aug 21, 2026; trading remains uninterrupted on the Nasdaq Global Market (symbol: PFSA).
• The company will submit the announcement to Nasdaq’s MarketWatch Department and will continue to monitor compliance with Nasdaq listing standards.

Why It Matters

• For investors: there is no immediate trading or listing disruption — PFSA shares remain listed and tradable on Nasdaq.
• The filing signals a short-term compliance concern tied directly to the reverse split, but Nasdaq’s subsequent determination of compliance removes an immediate delisting risk tied to the publicly held shares threshold.
• Investors should note the company’s continued cautionary language about forward‑looking statements and monitor future filings for any further Nasdaq correspondence or other listing-standard issues.
