On June 17, 2020, the Company entered into an underwriting agreement with A.G.P./Alliance Global Partners, as representative of the several underwriters named therein, relating to a firm commitment underwritten public offering pursuant to the S-1, of 4,762,000 shares of common stock, par value of $0.001 per share. The offering price to the public was $2.10 per share. The underwriters were granted a 45-day option to purchase up to 714,190 additional shares of common stock to cover over-allotments. Such option was exercised in full on June 18, 2020. The closing of the offering occurred on June 19, 2020. After deducting underwriting discounts and commissions and estimated offering expenses payable by the Company, BioCardia realized net proceeds of approximately $10.3 million. On June 8, 2020, the Company issued 29,625 shares of common stock to two former Board members to settle in lieu of cash their accrued board compensation liability of approximately $148,000. Lincoln Park Capital stock purchase agreement - On March 29, 2021, the Company and Lincoln Park Capital Fund, LLC (Lincoln Park) entered into a purchase agreement (the Purchase Agreement) and a registration rights agreement (the Registration Rights Agreement), pursuant to which the Company has the right to sell to Lincoln Park shares of the Company’s common stock having an aggregate value of up to $20 million, subject to certain limitations and conditions set forth in the Purchase Agreement (the Offering). As consideration for entering into the Purchase Agreement, the Company agreed to issue to Lincoln Park 75,000 shares of common stock as commitment shares. In addition, the Company agreed to issue to Lincoln Park up to an aggregate of 50,000 additional shares of common stock as a further commitment fee based on a pro-rata percentage of the $20 million of common stock issued to Lincoln Park under the Purchase Agreement. Pursuant to the Purchase Agreement, Lincoln Park purchased 373,832 shares of common stock, at a price of $5.35 per share, for a total gross purchase price of $2 million (the Initial Purchase) and the Company issued 80,000 shares of common stock as commitment shares, which included 5,000 commitment shares issued on a pro rata basis for the initial $2 million purchase. Thereafter, as often as every business day from and after one business day following the date of the Initial Purchase and over the 36-month term of the Purchase Agreement the Company has the right, from time to time, at its sole discretion and subject to certain conditions, to direct Lincoln Park to purchase up to 100,000 shares of common stock, with such amount increasing as the closing price of the common stock increases; provided Lincoln Park’s obligation under any single such purchase will not exceed $2 million, unless the Company and Lincoln Park mutually agree to increase the maximum amount of such single purchase (each, a Regular Purchase). If the Company directs Lincoln Park to purchase the maximum number of shares of common stock it then may sell in a Regular Purchase, then in addition to such Regular Purchase, and subject to certain conditions and limitations in the Purchase Agreement, the Company may direct Lincoln Park in an Accelerated Purchase to purchase an additional amount of common stock that may not exceed the lesser of (i) 300% of the number of shares purchased pursuant to the corresponding Regular Purchase in multiple Accelerated Purchases on the same trading day or (ii) 30% of the total number of shares of the Company’s common stock traded during a specified period on the applicable purchase date as set forth in the Purchase Agreement. Under certain circumstances and in accordance with the Purchase Agreement, the Company may direct Lincoln Park to purchase shares in multiple Accelerated Purchases on the same trading day. The Company controls the timing and amount of any sales of its common stock to Lincoln Park. There is no upper limit on the price per share that Lincoln Park must pay for its common stock under the Purchase Agreement. In no event may the Company issue or sell to Lincoln Park under the Purchase Agreement shares of the Company’s common stock in excess of 3,266,177 shares (including the commitment shares), which represents 19.99% of the shares of our common stock outstanding immediately prior to the execution of the Purchase Agreement (the Exchange Cap), unless (i) the Company obtains stockholder approval to issue shares of its common stock in excess of the Exchange Cap or (ii) the average price of all applicable sales of the Company’s common stock to Lincoln Park under the Purchase Agreement equals or exceeds $4.2736 per share. In all instances, the Company may not sell shares of its common stock to Lincoln Park under the purchase agreement if it would result in Lincoln Park beneficially owning more than 9.99% of its common stock. The Purchase Agreement does not limit the Company’s ability to raise capital from other sources at the Company’s sole discretion, except that during the 36 months after the date of the Purchase Agreement (subject to certain exceptions) the Company may not enter into any agreement to effect the issuance of its common stock or common stock equivalents in any “equity line of credit” or other similar continuous offering in which the Company may offer, issue or sell common stock or common stock equivalents at a future determined price, other than in connection with common stock issued pursuant to an “at-the-market offering” by the Company exclusively through a registered broker-dealer acting as agent of the Company pursuant to a written agreement between the Company and the registered broker-dealer. The Company has the right to terminate the Purchase Agreement at any time, at no cost to the Company. As of December 31, 2021, the Company had not sold any common stock to Lincoln Park under the Purchase Agreement other than the Initial Purchase.
