Stockholders' Equity

Stockholders’ Equity

Capital Structure

In conjunction with the completion of the Company’s initial public offering in September 2016, the Company amended its restated certificate of incorporation and amended and restated its bylaws. The amendment to the Company’s certificate of incorporation provided for 210,000,000 authorized shares of capital stock, of which 200,000,000 shares are designated as $0.0001 par value common stock and 10,000,000 shares are designated as $0.0001 par value preferred stock.

At the Company’s Annual Meeting of Stockholders held on July 28, 2020 (the “2020 Annual Meeting”), the Company’s stockholders approved an amendment to the Company’s restated certificate of incorporation of the Company to effect a reverse stock split of the Company’s common stock at a ratio of not less than one-for-two and not more than one-for-fifteen, with such ratio and the implementation and timing of such reverse stock split to be determined by the Company’s board of directors in its sole discretion. On May 18, 2021, the Company’s board of directors approved a one-for-ten reverse stock split of the Company’s issued and outstanding common stock. On May 24, 2021, the Company filed with the Secretary of State of the State of Delaware a Certificate of Amendment to the Restated Certification of Incorporation of the Company in order to effect the Reverse Stock Split. The Reverse Stock Split became effective as of 5:00 p.m. Eastern Time on May 25, 2021, and the Company’s common stock began trading on a split-adjusted basis on May 26, 2021. As a result of the Reverse Stock Split, on the effective date thereof, each outstanding ten (10) shares of common stock combined into and became one (1) share of common stock, and the number of the Company’s issued and outstanding shares of common stock was reduced to 15,170,678. The accompanying condensed consolidated financial statements and related notes give retroactive effect to the Reverse Stock Split.

The Company’s common stock has a par value of $0.0001 per share and consists of 200,000,000 authorized shares as of September 30, 2022 and December 31, 2021. There were 24,462,228 and 18,815,892 shares of voting common stock outstanding as of September 30, 2022 and December 31, 2021, respectively.

Preferred Stock

The Company’s restated certificate of incorporation provides the Company’s board of directors with the authority to issue $0.0001 par value preferred stock from time to time in one or more series by adopting a resolution and filing a certificate of designations. Voting powers, designations, preferences, dividend rights, conversion rights and liquidation preferences shall be stated and expressed in such resolutions. There were 10,000,000 shares designated as preferred stock and no shares outstanding as of September 30, 2022 and December 31, 2021.

March 2022 Equity Distribution Agreement – At-the-Market Facility

On March 11, 2022, the Company entered into an Equity Distribution Agreement (the “Equity Distribution Agreement”) with Oppenheimer & Co. Inc. (“Oppenheimer”). Pursuant to the Equity Distribution Agreement, the Company may from time to time issue and sell to or through Oppenheimer, acting as the Company’s sales agent, shares of the Company’s common stock, par value $0.0001 per share having an aggregate offering price of up to $50,000. Sales of the shares, if any, will be made by any method permitted by law deemed to be an “at the market offering” as defined in Rule 415(a)(4) promulgated under the Securities Act of 1933 (“Securities Act”), or, if expressly authorized by the Company, in privately negotiated transactions. As sales agent, Oppenheimer will offer the shares at prevailing market prices and will use its commercially reasonable efforts, consistent with its sales and trading practices, to sell on the Company’s behalf all of the shares requested to be sold by the Company, subject to the terms and conditions of the Equity Distribution Agreement. The Company or Oppenheimer may suspend the offering of the shares upon proper notice to the other party. The offering of the shares pursuant to the Equity Distribution Agreement will terminate upon the sale of shares in an aggregate offering amount equal to $50,000, or sooner if either the Company or Oppenheimer terminates the Equity Distribution Agreement as permitted by its terms.

The Company will pay Oppenheimer a commission equal to 3.0% of the aggregate gross proceeds from the sale of the shares sold pursuant to the Equity Distribution Agreement and will reimburse Oppenheimer for certain expenses incurred in connection with its services under the Equity Distribution Agreement. The foregoing rate of compensation will not apply when Oppenheimer acts as principal, in which case the Company may sell the shares to Oppenheimer as principal at a price agreed upon among the parties.

During the nine months ended September 30, 2022, the Company sold 385,025 shares of its common stock at an average price of approximately $3.58 per share for total net proceeds of $1,334 under the Equity Distribution Agreement.

In relation to the June 2022 Registered Direct Offering (as defined and described below), the Company agreed not to issue any additional securities in any variable rate transaction (as defined in the related securities purchase agreement), including under the Equity Distribution Agreement, until December 13, 2022, unless, on or after September 11, 2022, the VWAP (as defined in the related securities purchase agreement) for the trading day prior to the date of the transaction is greater than 50% above the exercise price for the June 2022 Common Warrants.

The following table presents the Company’s outstanding warrants to purchase common stock and pre-funded warrants for the periods indicated.

The weighted average exercise price per share for warrants outstanding as of September 30, 2022 and December 31, 2021 was $2.86 and $37.24, respectively.

June 2022 Registered Direct Offering

On June 9, 2022, the Company entered into a securities purchase agreement with an institutional investor (the “Purchaser”), pursuant to which the Company agreed to issue and sell to the Purchaser, in a registered direct offering priced at-the-market under Nasdaq rules (the “June 2022 Registered Direct Offering”) (i) 2,080,696 shares (the “June 2022 Shares”) of the Company’s common stock, and accompanying common stock warrants (the “June 2022 Common Warrants”) to purchase an aggregate of 2,080,696 shares of common stock, for a combined price of $2.851 per share and accompanying common warrant, and (ii) pre-funded warrants to purchase 3,180,615 shares of the Company’s common stock (the “June 2022 Pre-funded Warrants”) and accompanying common warrants to purchase 3,180,615 shares of common stock, for a combined price of $2.841 per pre-funded warrant and accompanying common warrant. The June 2022 Registered Direct Offering closed on June 13, 2022. Net proceeds from the offering were approximately $14,020 after deducting fees and commissions and offering expenses of approximately $948. Offering costs were netted against the offering proceeds and recorded to additional paid-in capital.

As of September 30, 2022, no June 2022 Pre-funded Warrants and 5,261,311 June 2022 Common Warrants are outstanding.

The Company entered into a placement agent agreement (the “Placement Agent Agreement”) dated as of June 9, 2022, engaging Oppenheimer to act as the sole placement agent in connection with the June 2022 Registered Direct Offering. Pursuant to the Placement Agent Agreement, the Company agreed to pay Oppenheimer a placement agent fee in cash equal to 5.0% of the gross proceeds from the sale of the June 2022 Shares, the June 2022 Pre-funded Warrants and the June 2022 Common Warrants, and to reimburse certain expenses of Oppenheimer in connection with the June 2022 Registered Direct Offering. Each June 2022 Pre-funded Warrant had an exercise price of $0.01 per share. The June 2022 Pre-funded Warrants were exercisable immediately upon issuance until all of the June 2022 Pre-funded Warrants were exercised in full. Each June 2022 Common Warrant is immediately exercisable and has an exercise price of $2.851 per share and will expire five years from the date of issuance.

The exercise price and the number of shares of common stock purchasable upon the exercise of the June 2022 Pre-funded Warrants and June 2022 Common Warrants are subject to adjustment upon the occurrence of specific events, including stock dividends, stock splits, reclassifications and combinations of the Company’s common stock.

Common warrants. The June 2022 Common Warrants include certain provisions that establish warrant holder settlement rights that take effect upon the occurrence of certain fundamental transactions. The June 2022 Common Warrants define a fundamental transaction to generally include any consolidation, merger or other transaction whereby another entity acquires more than 50% of the Company’s outstanding common stock or the sale of all or substantially all of the Company’s assets. The fundamental transaction provision provides the warrant holders with the option to settle any unexercised warrants for cash in the event of certain fundamental transactions that are within the control of the Company. For any fundamental transaction that is not within the control of the Company, including a fundamental transaction not approved by the Company’s board of directors, the warrant holder will only be entitled to receive from the Company or any successor entity the same type or form of consideration (and in the same proportion) that is being offered and paid to the stockholders of the Company in connection with the fundamental transaction, whether that consideration be in the form of cash, stock or any combination thereof. In the event of any fundamental transaction, and regardless of whether it is within the control of the Company, the settlement amount of the June 2022 Common Warrants (whether in cash, stock or a combination thereof) is determined based upon a Black-Scholes value that is calculated using inputs as specified in the June 2022 Common Warrants, including a defined volatility input equal to the greater of the Company’s 100-day historical volatility or 100%.

The June 2022 Common Warrants also include a separate provision whereby the exercisability of such warrants may be limited if, upon exercise, the warrant holder or any of its affiliates would beneficially own more than 4.99% (or an amount up to 9.99% if the holder so elects) of the Company’s common stock.

The Company assessed the June 2022 Common Warrants for appropriate equity or liability classification pursuant to the Company’s accounting policy described in Note 1—“Organization and Significant Accounting Policies.” During this assessment, the Company determined (i) the June 2022 Common Warrants did not constitute a liability under ASC 480; (ii) the June 2022 Common Warrants met the definition of a derivative under ASC 815; (iii) the warrant holder’s option to receive a net cash settlement payment under the June 2022 Common Warrants only becomes exercisable upon the occurrence of certain specified fundamental transactions that are within the control of the Company; (iv) upon the occurrence of a fundamental transaction that is not within the control of the Company, the warrant holder would receive the same type or form of consideration offered and paid to common stockholders; (v) the June 2022 Common Warrants are indexed to the Company’s common stock; and (vi) the June 2022 Common Warrants met all other conditions for equity classification under ASC 480 and ASC 815. Based on the results of this assessment, the Company concluded that the June 2022 Common Warrants are freestanding equity-linked derivative instruments that met the criteria for equity classification. Accordingly, the June 2022 Common Warrants were classified as equity and were accounted for as a component of additional paid-in capital at the time of issuance.

Pre-funded warrants. The June 2022 Pre-funded Warrants’ fundamental transaction provision did not provide the warrant holders with the option to settle any unexercised warrants for cash in the event of any fundamental transactions; rather, in all fundamental transaction scenarios, the warrant holder was only entitled to receive from the Company or any successor entity the same type or form of consideration (and in the same proportion) that was being offered and paid to the stockholders of the Company in connection with the fundamental transaction, whether that consideration be in the form of cash, stock or any combination thereof. The June 2022 Pre-funded Warrants also included a separate provision whereby the exercisability of the warrants could be limited if, upon exercise, the warrant holder or any of its affiliates would beneficially own more than 4.99% (or an amount up to 9.99% if the holder so elects) of the Company’s common stock.

The Company assessed the June 2022 Pre-funded Warrants for appropriate equity or liability classification pursuant to the Company’s accounting policy described in Note 1—“Organization and Significant Accounting Policies.” During this assessment, the Company determined the June 2022 Pre-funded Warrants were freestanding instruments that did not meet the definition of a liability pursuant to ASC 480 and did not meet the definition of a derivative pursuant to ASC 815. The June 2022 Pre-funded Warrants were indexed to the Company’s common stock and met all other conditions for equity classification under ASC 480 and ASC 815. Based on the results of this assessment, the Company concluded that the June 2022 Pre-funded Warrants were freestanding equity-linked financial instruments that met the criteria for equity classification under ASC 480 and ASC 815. Accordingly, the June 2022 Pre-funded Warrants were classified as equity and were accounted for as a component of additional paid-in capital at the time of issuance.

March 2020 Public Offering

On February 27, 2020, the Company entered into an underwriting agreement with H.C. Wainwright, as underwriter, relating to the offering, issuance and sale of common stock, pre-funded warrants, and accompanying common warrants (the “CMPO Common Warrants”), in a public offering (the “March 2020 Public Offering”). The number of CMPO Common Warrants, excluding pre-funded warrants, issued in connection with the March 2020 Public Offering totaled 2,108,333. At closing, the Company also issued to designees of H.C. Wainwright, as underwriter, warrants to purchase an aggregate of up to 59,496 shares of common stock (the “CMPO UW Warrants”) representing 3.0% of the aggregate number of shares of common stock sold and shares of common stock underlying the pre-funded warrants sold in the March 2020 Public Offering.

The CMPO Common Warrants have an exercise price of $3.00 per share and expire five years from the date of issuance. During the three and nine months ended September 30, 2022, there were no exercises of CMPO Common Warrants. During the nine months ended September 30, 2021, warrant holders exercised 10,000 of the CMPO Common Warrants for total proceeds of approximately $30. There were 252,417 of the CMPO Common Warrants outstanding as of September 30, 2022.

The CMPO UW Warrants have an exercise price of $3.75 per share and expire five years from the date of issuance. During the three and nine months ended September 30, 2022, there were no exercises of CMPO UW Warrants. During the nine months ended September 30, 2021, warrant holders exercised 48,192 of the CMPO UW Warrants for total proceeds of approximately $181.

March 2020 Registered Direct Offering

On March 24, 2020, the Company entered into a securities purchase agreement with several institutional and accredited investors, pursuant to which the Company agreed to sell and issue shares of the Company’s common stock and pre-funded warrants in a registered direct offering priced at the market (the “March 2020 Registered Direct Offering”). The March 2020

Registered Direct Offering closed on March 26, 2020. At closing, the Company issued to designees of H.C.

July 2020 Aspire Common Stock Purchase Agreement

On July 21, 2020, the Company entered into the Common Stock Purchase Agreement (the “July 2020 CSPA”) with Aspire Capital Fund, LLC (“Aspire”), which provided that, upon the terms and subject to the conditions and limitations set forth therein, Aspire was committed to purchase up to an aggregate of $30,000 of shares of the Company’s common stock at the Company’s request from time to time during the 30-month term of the July 2020 Aspire CSPA.
