3.01. Notice

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

On

October 12, 2026, Lucid Diagnostics Inc. (the “Company”) received a notice from the Listing Qualifications Department

of The Nasdaq Stock Market LLC (“Nasdaq”) stating that, for the prior 30 consecutive business days (through October

9, 2026), the closing bid price of the Company’s common stock had been below the minimum of $1 per share required for continued

listing on the Nasdaq Capital Market under Nasdaq Listing Rule 5550(a)(2).

The

notification letter stated that the Company would be afforded 180 calendar days (until April 12, 2027) to regain compliance. In order

to regain compliance, the closing bid price of the Company’s common stock must be at least $1 for a minimum of ten consecutive

business days. The notification letter also stated that, in the event the Company does not regain compliance within the initial 180-day

period, the Company may be eligible for an additional 180-day period. If the Company is not eligible for the additional 180-day period,

or if it appears to the Nasdaq staff that the Company will not be able to cure the deficiency, the Nasdaq Listing Qualifications Department

will provide notice after the end of the initial 180-day period that the Company’s securities will be subject to delisting.

The

Nasdaq notification has no effect at this time on the listing of the Company’s common stock, and the common stock will continue

to trade uninterrupted under the symbol “LUCD.” The Company intends to consider all available options to regain compliance

with the Nasdaq listing standards.
