Profusa Inc. said it has regained compliance with Nasdaq’s minimum shareholder requirements following a reverse stock split that restored its publicly held shares above the exchange’s threshold.
The Berkeley, California-based company executed a 1-for-4 reverse stock split in mid-August, which temporarily reduced its publicly held shares below the 500,000 minimum required under Nasdaq Listing Rule 5550(a)(4). Nasdaq notified Profusa of the deficiency shortly after the split took effect on August 14.
By August 21, Profusa provided documentation to Nasdaq demonstrating compliance, prompting the exchange to close its review and confirm the company met the listing rules. The exchange’s determination was conveyed to Profusa in a follow-up correspondence, according to the company’s disclosure.
Profusa’s shares continue to trade on The Nasdaq Capital Market under ticker symbol PFSA, and the company stated the notice has no impact on its listing status or trading activity. The announcement was made in accordance with Nasdaq Listing Rule 5810(b), which requires immediate public disclosure of deficiency notifications.
Profusa develops tissue-integrated sensors that transmit medical-grade data for personal and clinical use. The company did not disclose additional financial or operational details in its compliance update.
