Item 3.01. Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

As previously reported, on December 26, 2024, ProPhase Labs, Inc. (the “Company”) received a letter (the “Notice”) from the Listing Qualifications Staff (the “Staff”) of the Nasdaq Stock Market LLC (“Nasdaq”) informing the Company that because the closing bid price for the Company’s common stock listed on Nasdaq was below $1.00 for 30 consecutive trading days, the Company is not in compliance with the minimum bid price requirement for continued listing on the Nasdaq Capital Market, as set forth in Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Price Requirement”).

In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company had a period of 180 calendar days from December 26, 2024, or until June 24, 2025, to regain compliance with the Minimum Bid Price Requirement. The Nasdaq stated that one of the bases for its determination to grant the extension was the Company being in compliance with all other applicable requirements for initial listing on the Capital Market with the exception of the Minimum Bid Price Requirement.

On May 19, 2025, the Company submitted a request to the Nasdaq for a 180-day extension to regain compliance with the Minimum Bid Price Requirement pursuant to Nasdaq Listing Rule 5810(c)(3)(A)(ii). On June 25, 2025, the Company received a letter from the Nasdaq staff advising that the Company had been granted a 180-day extension to December 22, 2025 to regain compliance with the Minimum Bid Price Requirement, in accordance with Nasdaq Listing Rule 5810(c)(3)(A).

The Company intends to continue actively monitoring the closing bid price for the Company’s common stock between now and December 22, 2025, and will consider available options to resolve the deficiency to regain compliance with the Minimum Bid Price Requirement. To regain compliance, the Company’s Class A ordinary shares must have a closing bid price of at least US$1.00 per share for a minimum of 10 consecutive business days and the Company must receive approval of compliance from the Nasdaq Staff in accordance with applicable Listing Rules.

In the event that compliance cannot be demonstrated by December 22, 2025, the staff of the Nasdaq will provide the Company with written notification that the Company’s securities will be subject to delisting. The Company would then be entitled to request in writing that a Nasdaq Hearings Panel review the matter pursuant to Nasdaq Listing Rule 5815. However, under Nasdaq Listing Rule 5815(a)(1)(B)(ii)(d), a timely request for a hearing will not stay the suspension of the securities from trading for a Company afforded the second 180-day compliance period described in Rule 5810(c)(3)(A)(ii) that failed to regain compliance with the minimum bid price requirement during that period.

The Company is diligently working to evidence compliance with the Minimum Bid Price Requirement for continued listing on the Nasdaq; however, there can be no assurance that the Company will be able to regain compliance with the Minimum Bid Price Requirement during this 180-day extension period. If the Company fails to regain compliance with the Nasdaq continued listing standards, its common stock will be subject to delisting from the Nasdaq.
