<div style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">As previously disclosed on a Current Report on Form 8-K filed with the Securities and Exchange Commission (the &#8220;SEC&#8221;) on September 12, 2023, on September 6, 2023, BioCardia, Inc. (the &#8220;Company&#8221;) received a written notice (the &#8220;MVLS Notice&#8221;) from the Nasdaq Listing Qualifications staff (the &#8220;Staff&#8221;) of The Nasdaq Stock Market LLC (&#8220;Nasdaq&#8221;) indicating that, for the last 30 consecutive business days, the Market Value of Listed Securities, as defined by Nasdaq, had been below the $35 million minimum requirement for continued listing on the Nasdaq Capital Market under Nasdaq Listing Rule 5550(b)(2) (the &#8220;MVLS Requirement&#8221;). The MVLS Notice provided that, in accordance with Nasdaq Listing Rule 5810(c)(3)(C), the Company would have an initial period of 180 calendar days, or until March 4, 2024 (the &#8220;MVLS Compliance Date&#8221;), to regain compliance with the MVLS Requirement.</div>

<div style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#160;</div>

<div style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">On March 6, 2024, the Company received a determination letter from the Staff advising the Company that it had failed to regain compliance with the MVLS Requirement by the MVLS Compliance Date and that unless the Company requested an appeal of this determination before a Nasdaq Hearings Panel (the &#8220;Panel&#8221;) by March 13, 2024, trading of the Company&#8217;s currently listed securities would be suspended at the opening of business on March 15, 2024, and a Form 25-NSE would be filed with the SEC to remove the Company&#8217;s securities from listing and registration on the Nasdaq (the &#8220;MVLS Determination Letter&#8221;). The Company submitted the Panel hearing request with respect to the MVLS Determination Letter on March 12, 2024.</div>

<div style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#160;</div>

<div style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">Additionally, as previously disclosed on a Current Report on Form 8-K filed with the SEC on September 15, 2023, on September 13, 2023, the Company received a separate written notice (the &#8220;Minimum Bid-Price Notice&#8221;) from Nasdaq, indicating that the Company was no longer 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 &#8220;Minimum Bid Price Requirement&#8221;). The Minimum Bid-Price Notice provided that, in accordance with Nasdaq Listing Rule 5810(c)(3)(C), the Company would have an initial period of 180 calendar days, or until March 11, 2024 (the &#8220;Minimum Bid Price Compliance Date&#8221;), to regain compliance with the Minimum Bid Price Requirement. On March 12, 2024, the Company received a determination letter from the Staff advising the Company that it had failed to regain compliance with the Minimum Bid Price Requirement by the Minimum Bid Price Compliance Date (the &#8220;Minimum Bid Price Determination Letter&#8221;). The Minimum Bid Price Determination Letter indicates that the Panel will also consider this matter in their decision regarding the Company&#8217;s continued listing on the Nasdaq Capital Market.</div>

<div style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#160;</div>

<div style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">The hearing request submitted by the Company described above will stay any delisting or suspension of the Company&#8217;s securities and the filing of a Form 25-NSE pending the Panel&#8217;s decision with respect to both the MVLS Determination Letter and the Minimum Bid Price Determination Letter. While the Company will present a plan to regain compliance with respect to both the MVLS Requirement and the Minimum Bid Price Requirement before the Panel, there can be no assurance that such Panel will grant the Company&#8217;s request for continued listing or, even if it does, that the Company will otherwise be able to regain compliance with the applicable Nasdaq listing requirements.</div>

<div style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#160;</div>

<div style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">If the Company&#8217;s securities are delisted from the Nasdaq Capital Market, it could be more difficult to buy or sell the Company&#8217;s securities or to obtain accurate quotations, and the price of the Company&#8217;s securities could suffer a material decline. Delisting could also impair the Company&#8217;s ability to raise capital and/or trigger defaults and penalties under outstanding agreements or securities of the Company.</div>

The risks and uncertainties that may cause actual results to differ materially from the Company&#8217;s current expectations are more fully described in the Company&#8217;s Annual Report on Form 10-K filed with the SEC on March 29, 2023, as amended, any subsequently filed Quarterly Reports on Form 10-Q, and its other reports, each as filed with the SEC.
