Equity [Abstract] |
STOCKHOLDERS’ EQUITY | 10. STOCKHOLDERS’ EQUITY In September 2018, the Company filed with the SEC a $75 million shelf registration statement on Form S-3 (the 2018 Shelf Registration Statement) that allows the Company to issue any combination of common stock, preferred stock or warrants to purchase common stock or preferred stock. This shelf registration was declared effective on October 12, 2018 and during January 2021, has been fully utilized. On March 19, 2021, the Company filed with the SEC a new $100 million shelf registration statement on Form S-3 (the “2021 Registration Statement”) that allows the Company to issue any combination of common stock, preferred stock or warrants to purchase common stock or preferred stock. This shelf registration was declared effective on March 30, 2021. Reverse Stock Split On February 28, 2022, the Company effected a 15-for-1 reverse stock split of its common stock which was made effective for trading purposes as of the commencement of trading on March 31, 2022. As of that date, each 15 shares of issued and outstanding common stock and equivalents was consolidated into one share of common stock. All shares have been restated to reflect the effects of the 15-for-1 reverse stock split. In addition, at the market open on March 1, 2022, the Company’s common stock started trading under a new CUSIP number 15117N602 although the Company’s ticker symbol, CLSN, remained unchanged. The reverse stock split was previously approved by the Company’s stockholders at the 2022 Special Meeting held on February 24, 2022, and the Company subsequently filed a Certificate of Amendment to its Certificate of Incorporation to effect the stock consolidation. The primary reasons for the reverse stock split and the amendment are:
| ● | To provide the Company with the ability to support its future anticipated growth and would provide greater flexibility to consider and respond to future business opportunities and needs as they arise, including equity financings and stock-based acquisitions of new technology and product development candidates. The availability of additional shares of Common Stock would permit the Company to undertake certain of the foregoing actions without delay and expense associated with holding a Special Meeting of Stockholders to obtain stockholder approval each time such an opportunity arises that would require the issuance of shares of our Common Stock; and,
| ● | To continue listing on The NASDAQ Capital Market, which requires that the Company comply with the applicable listing requirements under NASDAQ Marketplace Rules, which requirements include, among others, a minimum bid price of at least $1.00 per share. On December 2, 2021, the Company received a letter from NASDAQ indicating that the closing bid price of the Company’s Common Stock fell below $1.00 per share for the previous 30 consecutive business days, and that the Company was therefore not in compliance with the minimum bid price requirement for continued inclusion on The NASDAQ Capital Market. The Company had 180 calendar days, until May 31, 2022, to regain compliance with this requirement, which occurs when the closing bid price of the Company’s Common Stock is at least $1.00 per share for a minimum of ten consecutive business days during the 180-day compliance period.
Immediately prior to the reverse stock split, the Company had 86,557,736 shares of common stock outstanding which consolidated into 5,770,516 shares of the Company’s common stock. No fractional shares were issued in connection with the reverse stock split. Holders of fractional shares have been paid out in cash for the fractional portion with the Company’s overall exposure for such payouts consisting of a nominal amount. The amount of the Company’s outstanding convertible preferred stock were not affected by the reverse stock split. The number of outstanding options, stock awards and warrants were adjusted accordingly, with outstanding options and stock awards being reduced from approximately 6.6 million to approximately 0.4 million and outstanding warrants being reduced from approximately 2.5 million to approximately 0.2 million. Capital on DemandTM Sales Agreement On December 4, 2018, the Company entered into the Capital on Demand Agreement with JonesTrading, pursuant to which the Company may offer and sell, from time to time, through JonesTrading shares of Common Stock having an aggregate offering price of up to $16.0 million. During 2020, the Company sold and issued an aggregate of 0.3 million shares under the Capital on Demand Agreement, receiving approximately $6.2 million in gross proceeds. During 2021, the Company has sold 0.5 million shares under the Capital on Demand Agreement, receiving approximately $6.9 million in gross proceeds under the Capital on Demand Agreement. February 2020 Registered Direct Offering On February 27, 2020, the Company entered into a Securities Purchase Agreement (the “February 2020 Purchase Agreement”) with several institutional investors, pursuant to which the Company issued and sold, in a registered direct offering (the “February 2020 Offering”), an aggregate of 304,761 shares of its common stock at an offering price of $15.75 per share for gross proceeds of approximately $4.8 million before the deduction of the Placement Agent fees and offering expenses. The February 2020 Purchase Agreement contained customary representations, warranties and agreements by the Company and customary conditions to closing. In a concurrent private placement, the Company issued to the investors that participated in the February 2020 Offering, for no additional consideration, warrants to purchase up to 198,095 shares of common stock (the “Original Warrants”). The Original Warrants were initially exercisable six months following their date of issue and were set to expire on the five-year anniversary of such initial exercise date. The Original Warrants had an exercise price of $17.25 per share subject to adjustment as provided therein. On March 12, 2020, the Company entered into private exchange agreements (the “Exchange Agreements”) with holders of the Original Warrants. Pursuant to the Exchange Agreements, in return for a higher exercise price of $18.60 per share of Common Stock, the Company issued new warrants to the investors to purchase up to 213,333 shares of Common Stock (the “Exchange Warrants”) in exchange for the Original Warrants. The Exchange Warrants, like the Original Warrants, are initially exercisable six months following their issuance (the “Initial Exercise Date”) and expire on the five-year anniversary of their Initial Exercise Date. Other than having a higher exercise price, different issue date, Initial Exercise Date and expiration date, the terms of the Exchange Warrants are identical to those of the Original Warrants. On July 31, 2020, the Company filed a Form S-3 Registration Statement to register the shares of common stock issuable under the Exchange Warrants; the Registration Statement was declared effective by the SEC on August 13, 2020. No Exchange Warrants were exercised during 2020. During 2021, the Company has issued 81,111 million shares pursuant to investors exercising Exchange Warrants, receiving approximately $1.5 million. Underwritten Offering On June 22, 2020, the Company entered into an underwriting agreement (the “Underwriting Agreement”) with Oppenheimer & Co. Inc. (the “Underwriter”), relating to the issuance and sale (the “Underwritten Offering”) of 177,777 shares of the Company’s common stock. Pursuant to the terms of the Underwriting Agreement, the Underwriter agreed to purchase the shares at a price of $52.3125 per share. The Underwriter offered the shares at a public offering price of $56.25 per share, reflecting an underwriting discount equal to $3.9375, or 7.0% of the public offering price. The net proceeds to the Company from the Underwritten Offering, after deducting the underwriting discount and estimated offering expenses payable by the Company, were approximately $9.1 million. The Underwriting Agreement contains customary representations, warranties and agreements by the Company, customary conditions to closing, indemnification obligations of the Company and the Underwriter including for liabilities under the Securities Act, other obligations of the parties, and termination provisions. Pursuant to the Underwriting Agreement, until December 31, 2020, the Underwriter had a right of first refusal to act as sole underwriter, initial purchaser, placement/selling agent, or arranger, as the case may be, on any new financing for the Company (excluding equipment lease financings, loans or grants from governmental authorities or in connection with government programs and financings relating to or sales of tax attributes) during such period. The Underwriter had the sole right to determine whether or not any other broker dealer shall have the right to participate in any such offering and the economic terms of any such participation. Pursuant to the Underwriting Agreement, subject to certain exceptions, the Company and certain of the Company’s executive officers and directors agreed that, without the prior written consent of the Underwriter and subject to certain negotiated exceptions, they will not, for a period of 60 days, in either case, following the date of the final prospectus supplement, sell or otherwise dispose of any of the Company’s securities held by them. LPC Purchase Agreement On September 8, 2020, the Company entered into a purchase agreement (the “LPC Purchase Agreement”) and a Registration Rights Agreement (the “Registration Rights Agreement”) with Lincoln Park Capital Fund, LLC (“Lincoln Park”), pursuant to which, upon the terms and subject to the conditions and limitations set forth therein, the Company has the right to sell to Lincoln Park up to $26.0 million of shares of the Company’s common stock at the Company’s discretion. During 2020, the Company sold and issued an aggregate of 218,854 shares, including 29,188 commitment shares provided to Lincoln Park, under the LPC Purchase Agreement, receiving approximately $2.2 million in gross proceeds. On January 21, 2021, the Company terminated the LPC Purchase Agreement. The Company did not sell any shares under the LPC Purchase Agreement in 2021. January 2021 Registered Direct Offering On January 22, 2021, the Company entered into a Securities Purchase Agreement (the “January 2021 Purchase Agreement”) with several institutional investors, pursuant to which the Company issued and sold, in a registered direct offering (the “January 2021 Offering”), an aggregate of 1,728,395 shares of the Company’s common stock at an offering price of $20.25 per share for gross proceeds of approximately $35 million before the deduction of the January 2021 Placement Agents (as defined below) fee and offering expenses. The closing of the January 2021 Offering occurred on January 26, 2021. In connection with the January 2021 Offering, the Company entered into a placement agent agreement with A.G.P./Alliance Global Partners (“AGP,” and together with Brookline Capital Markets, the “January 2021 Placement Agents”) pursuant to which the Company agreed to pay the January 2021 Placement Agents a cash fee equal to 7% of the aggregate gross proceeds raised from the sale of the securities sold in the January 2021 Offering and reimburse the January 2021 Placement Agents for certain of their expenses in an amount not to exceed $82,500. March 2021 Registered Direct Offering On March 31, 2021, the Company entered into a Securities Purchase Agreement (the “March 2021 Purchase Agreement”) with several institutional investors, pursuant to which the Company issued and sold, in a registered direct offering (the “March 2021 Offering”), an aggregate of 769,230 shares of the Company’s common stock, at an offering price of $19.50 per share for gross proceeds of approximately $15 million before the deduction of the placement agents fee and offering expenses. The closing of the offering occurred on April 5, 2021. In connection with the March 2021 Offering, the Company entered into a placement agent agreement (the “March 2021 Placement Agent Agreement”) with AGP, as lead placement agent (together with JonesTrading Institutional Services LLC and Brookline Capital Markets, a division of Arcadia Securities, LLC, serving as co-placement agents, the “March 2021 Placement Agents”), pursuant to which the Company agreed to pay the March 2021 Placement Agents an aggregate cash fee equal to 7% of the aggregate gross proceeds raised from the sale of the securities sold in the offering and reimburse the Placement Agents for certain of their expenses in an amount not to exceed $82,500. Under the March 2021 Purchase Agreement and March 2021 Placement Agent Agreement, the Company and its subsidiaries were prohibited, for a period of 90 days after the closing, from entering into any agreement to issue or announcing any issuance or proposed issuance of common stock or any other securities that are at any time convertible into, or exercisable or exchangeable for, or otherwise entitle the holder thereof to receive common stock without the prior written consent of AGP or the investors participating in the offering. For purposes of this offering, AGP and the investors from the Company’s January 2021 Offering waived a similar 90-day restriction in the placement agent agreement and purchase agreement for that transaction. 2019 Aspire Purchase Agreement In 2019, Company, entered into the 2019 Aspire Purchase Agreement with Aspire Capital. Pursuant to the 2019 Aspire Purchase Agreement, Aspire Capital was committed to purchase up to an aggregate of $10.0 million of shares of the Company’s common stock over the 24-month term of the 2019 Aspire Purchase Agreement. On March 5, 2020, the Company delivered notice to Aspire Capital terminating the 2019 Aspire Purchase Agreement effective as of March 6, 2020. During the first quarter of 2020, the Company sold 66,666 million shares of common stock under the 2019 Aspire Purchase Agreement and received $1.6 million in gross proceeds. Series A and Series B Convertible Redeemable Preferred Stock Offering On January 10, 2022, the Company entered into a Securities Purchase Agreement (the “Preferred Stock Purchase Agreement”) with several institutional investors, pursuant to which the Company agreed to issue and sell, in concurrent registered direct offerings (the “Preferred Offerings”), (i) 50,000 shares of the Company’s Series A Convertible Redeemable Preferred Stock, par value $0.01 per share (the “Series A Preferred Stock”), and (ii) 50,000 shares of the Company’s Series B Convertible Redeemable Preferred Stock, par value $0.01 per share (the “Series B Preferred Stock” and together with the Series A Preferred Stock, the “Preferred Stock”), in each case at an offering price of $285 per share, representing a 5% original issue discount to the stated value of $300 per share, for gross proceeds of each Preferred Offering of $14.25 million, or approximately $28.50 million in the aggregate for the Preferred Offerings, before the deduction of the Placement Agent’s (as defined below) fee and offering expenses. The shares of Series A Preferred Stock have a stated value of $300 per share and are convertible, at a conversion price of $13.65 per share, into 1,098,901 shares of common stock (subject in certain circumstances to adjustments). The shares of Series B Preferred Stock have a stated value of $300 per share and are convertible, at a conversion price of $15.00 per share, into 1,000,000 shares of common stock (subject in certain circumstances to adjustments). The closing of the Preferred Offerings occurred on January 13, 2022. The Company held a special meeting of stockholders to consider an amendment (the “Amendment”) to the Company’s Certificate of Incorporation, as amended (the “Charter”), to effect a reverse stock split of the outstanding shares of common stock (“Common Stock”) by a ratio to be determined by the Board of Directors of the Company (the “Reverse Stock Split”), ranging from 7-to-1 to, 10-to-1, 12-to-1 or 15-to-1. The investors have agreed in the Purchase Agreement to not transfer, offer, sell, contract to sell, hypothecate, pledge or otherwise dispose of the shares of the Preferred Stock until the Reverse Stock Split, to vote the shares of the Series A Preferred Stock purchased in the Preferred Offerings in favor of such Amendment and to vote the shares of the Series B Preferred Stock purchased in the Preferred Offerings in a manner that “mirrors” the proportions on which the shares of Common Stock (excluding any shares of Common Stock that are not voted) and Series A Preferred Stock are voted on the Reverse Stock Split and the Amendment. The Amendment required the approval of the majority of the votes associated with the Company’s outstanding stock entitled to vote on the proposal. Pursuant to the Purchase Agreement, the Company filed two certificates of designation (the “Certificates of Designation”) with the Secretary of the State of Delaware designating the rights, preferences and limitations of the shares of Preferred Stock. The Certificates of Designation provided, in particular, that the Preferred Stock has no voting rights, other than the right to vote as a class on certain specified matters, except that (i) each share of Series A Preferred Stock has the right to vote, on an as converted basis, on the Reverse Stock Split (together with the Company’s Common Stock and the Series B Preferred Stock as a single class), and (ii) each share of Series B Preferred Stock has the right to cast 3,000 votes per share of Series B Preferred Stock on the Reverse Stock Split. The holder of Preferred Stock will be entitled to dividends, on an as-if converted basis, equal to dividends actually paid, if any, on shares of Common Stock. The Preferred Stock is convertible into shares of Common Stock at a rate of $13.65 per share for the Series A Preferred Stock and $15.00 per share for the Series B Preferred Stock, subject to adjustment. The Preferred Stock can be converted at the option of the holder at any time after the Company has received stockholder approval for the Reverse Stock Split and filed the requisite Amendment with the Delaware Secretary of State’s office to effectuate the Reverse Stock Split (the “Reverse Stock Split Date”), subject to beneficial ownership limitations set forth in the applicable Certificate of Designation. In addition, on or after the Reverse Stock Split Date, and subject to the satisfaction of certain conditions, the Company can cause the holder of the Preferred Stock to convert their shares of Preferred Stock, subject to such beneficial ownership limitations. Each holder of the Preferred Stock has the right to cause the Company to redeem all or part of their shares of the Preferred Stock from the earlier of receipt of stockholder approval of the Reverse Stock Split or of 90 days following the original issue date until 120 days following the original issue date, the “Redemption Date,” in cash at a redemption price equal to 105% of the stated value plus an amount equal to accumulated but unpaid dividends, if any, on such shares (whether or not earned or declared, but excluding interest on such dividends) up to, but excluding, the Redemption Date. On March 3, 2022, the Company redeemed for cash at a price equal to 105% of the $300 stated value per share all of its 50,000 outstanding shares of Series A Preferred Stock and its 50,000 Series B Preferred Stock. As a result, all shares of the Preferred Stock have been retired and are no longer outstanding and Celsion’s only class of outstanding stock is its common. Each share of common stock entitles the holder to one vote. In connection with the Preferred Offerings, the Company entered into a placement agent agreement (the “Placement Agent Agreement”) with AGP pursuant to which the Company agreed to pay AGP an aggregate cash fee equal to $1,000,000 and reimburse AGP for certain of their expenses in an amount not to exceed $110,000. The Placement Agent Agreement contains customary representations, warranties and agreements by the Company, customary conditions to closing, indemnification obligations of the Company and AGP, including for liabilities under the Securities Act, other obligations of the parties and termination provisions.
