Failure to Satisfy Listing Rule (Form 8-K)

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

As previously disclosed on that certain Current Report on Form 8-K filed with the Securities and Exchange Commission (the "SEC") on April 15, 2026 (the "Original 8-K"), on April 10, 2026, BioCardia, Inc. (the "Company," "we," "us" and "our") received a notification letter (the "Notice") from the Nasdaq Listing Qualifications Staff (the "Staff") of The Nasdaq Stock Market LLC ("Nasdaq") notifying the Company that its amount of stockholders' equity had fallen below the $2,500,000 required minimum for continued listing set forth in Nasdaq Listing Rule 5550(b)(1).

As noted in the Original 8-K, the Company had until May 25, 2026 to provide Nasdaq with a specific plan to achieve and sustain compliance. The Company submitted its plan to regain compliance on May 25, 2026, and on June 9, 2026, received written notice that, based on review of the compliance plan, the Nasdaq staff granted the Company an extension to October 7, 2026 to regain compliance with the Rule. The Company is filing this Current Report on Form 8-K (this "Report") to provide an update to its compliance with continued listing requirements as set forth in Nasdaq Listing Rule 5550(b)(1).

On June 8, 2026, the Company filed an 8-K and issued a press release announcing that the Company sold 3,509,604 shares at an average price of $1.279 on Friday, June 5, 2026. The shares were sold pursuant to the Company's "At The Market" offering agreement with H.C. Wainwright & Co. (the "Sales Agreement"). Under the Sales Agreement, from April 1, 2026 to June 5, 2026, we sold an aggregate of 4,004,330 shares of common stock at an average share price of $1.27, resulting in net proceeds of $4.9 million after deducting fees and expenses.

As a result of these transactions, the Company believes it has regained compliance with the minimum $2.5 million stockholders' equity requirement for continued listing as set forth in Nasdaq Listing Rule 5550(b)(1). In that regard, the Company believes that as of the date of this Report, stockholders' equity exceeds $2.5 million. Nasdaq will continue to monitor the Company's ongoing compliance with the stockholders' equity requirement and, if at the time of its next periodic report the Company does not evidence compliance, it may be subject to delisting.
