6. STOCKHOLDERS’ EQUITY October 2022 Public Offering and Private Placement On October 25, 2022, we completed a registered direct offering of 3,275,153 shares of the Company’s common stock at $2.085 per share and warrants to purchase up to an aggregate of 3,275,153 shares of common stock in a concurrent private placement priced at-the-market under Nasdaq rules. In a separate concurrent private placement transaction, the Company offered and sold pre-funded warrants to purchase an aggregate of 1,875,945 shares of common stock and warrants to purchase an aggregate of 1,875,945 shares of common stock. The warrants are immediately exercisable at an exercise price of $1.96 per share and will expire on the fifth anniversary of the closing date. Each pre-funded warrant had a purchase price of $2.08499, is immediately exercisable at an exercise price of $0.00001 per share and will not expire until exercised in full. The registered direct offering and private placements resulted in total gross proceeds of approximately $10.7 million with net proceeds to the Company of approximately $9.6 million after deducting estimated offering expenses. In accordance with the concept of ASC 820 regarding the October 2022 public offering, the Company allocated the value of the proceeds to the common stock, common warrants, and pre-funded warrants utilizing a relative fair value basis. Using the Nasdaq closing trading price for our stock on October 20, 2022, the Company computed the fair value of the shares sold. This valuation did not impact the total gross increase to Stockholders’ Equity of $10.7 million, but is an internal, proportionate calculation allocating gross proceeds of approximately $4.0 million to common stock, $4.4 million to common warrants and $2.3 million to pre-funded warrants. 2022 Reverse Stock Split At the annual stockholders’ meeting held on June 24, 2022, the Company’s stockholders approved an amendment to the Company’s certificate of incorporation to effect a reverse split of the Company’s common stock at a ratio between -for-5 to -for-10 in order to satisfy requirements for the continued listing of the Company’s common stock on Nasdaq. The board of directors authorized the -for-10 ratio of the reverse split on June 27, 2022, and effective at the close of business on July 21, 2022, the Company’s certificate of incorporation was amended to effect a -for-10 reverse split of the Company’s common stock (the “Reverse Stock Split”). The accompanying consolidated financial statements and notes to consolidated financial statements give retroactive effect to the Reverse Stock Split for all periods presented.Authorized Share Increase At a special meeting held on February 25, 2021, the Company’s stockholders approved the amendment of the Company’s Second Amended and Restated Certificate of Incorporation, as amended, to increase the authorized common stock from 80,000,000 shares to 160,000,000 shares. Equity Distribution Agreement On August 11, 2020, the Company entered into an equity distribution agreement (the Sales Agreement) with Oppenheimer & Co. Inc. (the Sales Agent). Pursuant to the Sales Agreement, the Company may offer and sell from time-to-time through the Sales Agent, up to $14.5 million shares of the Company’s common stock, par value $0.00001 per share (the ATM Shares). The Sales Agent will receive from the Company a commission of 3.0% of the gross proceeds from the sales of the ATM Shares pursuant to the terms of the Sales Agreement. The offering of the ATM Shares pursuant to the Sales Agreement will terminate upon the earliest of (i) the sale of all ATM Shares subject to the Sales Agreement, and (ii) the termination of the Sales Agreement by the Company or the Sales Agent. Net proceeds from the sale of the ATM Shares will be used for general corporate purposes, including working capital. The ATM Shares issued under the Sales Agreement are offered pursuant to a registration statement on Form S-3, which was declared effective by the U.S. Securities and Exchange Commission (SEC) on August 20, 2020. In June 2021, the Company issued and sold an aggregate of 4,169 ATM Shares pursuant to the Sales Agreement and received gross proceeds of approximately $69,000 and net proceeds of $35,000 after deducting commissions to the Sales Agent and other offering expenses. In conjunction with the October 2022 offering, the Company filed a prospectus supplement suspending the ATM program. The Company will not make any sales of its common stock pursuant to the Equity Distribution Agreement unless and until a new prospectus supplement is filed with the SEC; however, the Equity Distribution Agreement remains in full force and effect. December 2020 Public Offering and Private Placement On December 23, 2020, the Company issued and sold 1,814,813 shares of common stock, par value $0.00001 per share, at a public offering price of $13.50 per share of common stock, prior to deducting underwriting discounts and commissions and estimated offering expenses. In a concurrent private placement, the Company issued and sold 1,518.5180 shares of Series D convertible preferred stock. These preferred shares are convertible into a number of shares of common stock equal to $13,500 divided by $13.50 (or 1,000 shares of common stock for each share of Series D preferred stock converted) and were issued at a price of $13,500 per share of Series D preferred stock. The preferred shares were only convertible into common stock upon receipt of stockholder approval of the issuance of the underlying shares of common stock as required by Nasdaq Marketplace Rule 5635(d) at a special stockholder meeting to be called for that purpose. At a special meeting of stockholders held on February 25, 2021, the stockholders approved, in accordance with Nasdaq Listing Rule 5635(d), the issuance of shares of the Company’s common stock upon the conversion of the Series D preferred stock. During the twelve months ended December 31, 2021, 1,407.4036 shares of our Series D convertible preferred stock were converted into 1,407,404 shares of common stock at the established conversion rate. There were no preferred stock conversions in the twelve months ended December 31, 2022. The net proceeds of the December 2020 public offering and private placement to the Company, after deducting underwriting discounts and commissions, placement agency fees, and estimated offering expenses payable by the Company, were approximately $41.4 million. The common stock issued in the public offering was offered by the Company pursuant to a registration statement on Form S-3, which was declared effective by the SEC on August 20, 2020. The common stock issuable upon conversion of the Series D preferred stock in the private placement was offered by the Company pursuant to a registration statement on Form S-3, which was declared effective by the SEC on February 1, 2021. In accordance with the concept of ASC 820 regarding the December 2020 public offering, the Company allocated the value of the proceeds to the common stock and preferred stock utilizing a relative fair value basis. Using the Nasdaq closing trading price for our stock on December 28, 2020, the Company computed the fair value of the shares sold. The fair value of the preferred stock was estimated on a relative fair value basis. This valuation did not impact the total increase to Stockholders’ Equity of $45.0 million, but is an internal, proportionate calculation allocating gross proceeds of approximately $24.5 million to common stock and $20.5 million to preferred stock.
