Equity [Abstract] |
Equity | Note 10 – Equity Pursuant to the Company’s Amended and Restated Certificate of Incorporation (“Charter”), effective as of March 4, 2022, the total number of shares of all classes of stock that the Company has the authority to issue is 200,000,000, consisting of 190,000,000 shares of common stock, par value $0.001 per share, and 10,000,000 shares of preferred stock, par value $0.001 per share. Preferred Stock Preferred stock may be issued from time to time in one or more series at the direction of the Company’s Board of Directors and the directors also have the ability to fix dividend rates and rights, liquidation preferences, voting rights, conversion rights, rights and terms of redemption and other rights, preferences, privileges and restrictions as determined by the Company’s Board of Directors, subject to certain limitations set forth in the Charter. Series A Voting Preferred Stock On March 8, 2022, the Company formalized the issuance of preferred stock as was required under the terms of the Company's May 2021 financing agreements with Energy Evolution and issued six shares of Series A Voting Preferred Stock. The Series A Voting Preferred Stock was issued in connection with the strategic investment in the Company by Energy Evolution. For so long as the Series A Voting Preferred Stock is outstanding, the Company’s Board of Directors will consist of six directors. Three of the directors are designated as the Series A Directors and the three other directors (each, a “common director”) are elected by the holders of common stock and/or any preferred stock (other than the Series A Voting Preferred Stock) granted the right to vote on the common directors. Any Series A Director may be removed with or without cause but only by the affirmative vote of the holders of a majority of the Series A Voting Preferred Stock voting separately and as a single class. The holders of the Series A Voting Preferred Stock have the exclusive right, voting separately and as a single class, to vote on the election, removal and/or replacement of the Series A Directors. Holders of common stock or other preferred stock do not have the right to vote on the Series A Directors. The approval of the holders of the Series A Voting Preferred Stock, voting separately and as a single class, is required to authorize any resolution or other action to issue or modify the number, voting rights or any other rights, privileges, benefits, or characteristics of the Series A Voting Preferred Stock, including without limitation, any action to modify the number, structure and/or composition of the Company’s current Board of Directors. The Series A Voting Preferred Stock is held by Phil Mulacek, Chairman of the Board of Directors of the Company and one of the principals of Energy Evolution, as Energy Evolution’s designee (the “Initial Holder”). The Series A Voting Preferred Stock may be transferred only to certain controlled affiliates of the Initial Holder (“Permitted Transferees”), and the voting rights of the Series A Voting Preferred Stock are contingent upon the Initial Holder and Permitted Transferees (collectively, the “Series A Holders”) holding together at least 3,000,000 shares of the Company’s outstanding common stock. The Series A Voting Preferred Stock is not entitled to receive any dividends or distributions of cash or other property except in the event of any liquidation, dissolution or winding up of the Company’s affairs. In such event, before any amount is paid to the holders of the Company’s common stock but after any amount is paid to the holders of the Company’s senior securities, the holders of the Series A Voting Preferred Stock will be entitled to receive an amount per share equal to $1.00. Except as discussed above or as otherwise set forth in the certificate of designation of the Series A Voting Preferred Stock, the holders of the Series A Voting Preferred Stock have no voting rights. The Series A Voting Preferred Stock is not redeemable at the Company’s election or the election of any holder, except the Company may elect to redeem the Series A Voting Preferred Stock for $1.00 per share following satisfaction of its notice and cure requirements in the event that:
| • | any or all shares of Series A Voting Preferred Stock are held by anyone other than the Initial Holder or a Permitted Transferee; or
| • | the Series A Holders together hold less than 3,000,000 shares of the Company’s outstanding common stock.
The Series A Voting Preferred Stock is not convertible into common stock or any other security. Common Stock On August 27, 2021, the Company’s Board of Directors approved a one-for-four reverse stock split such that every holder of the Company’s common stock would receive one share of common stock for every four shares owned. The reverse stock split was effective as of 6:00 p.m. Eastern Time on March 7, 2022, immediately prior to the Company’s listing of its common stock on the NYSE American. All share amounts have retrospectively been stated at post-reverse split amounts and pricing. The holders of shares of common stock are entitled to one vote per share for all matters on which common stockholders are authorized to vote on. Examples of matters that common stockholders are entitled to vote on include, but are not limited to, the election of three of the six directors and other common voting situations afforded to common stockholders. In April 2024, Empire completed a subscription rights offering (the "April Rights Offering”) which raised gross proceeds of $20.7 million. Empire distributed at no charge to holders of its common stock, as of the close of business on March 7, 2024 (the record date for the April Rights Offering), one subscription right for each share of common stock held. Each subscription right entitled the holder to purchase 0.161 shares of common stock at a subscription price of $5.00 per share per one whole share of common stock. The subscription rights were non-transferable and not listed for trading on any stock exchange or market. On May 31, 2024, Empire issued Energy Evolution a warrant certificate granting them the right to purchase 128,800 shares of common stock of Empire at $5.00 per share. On June 28, 2024, Energy Evolution exercised the warrants and received 128,800 shares in exchange for approximately $0.6 million. In November 2024, Empire completed a subscription rights offering (the "November Rights Offering”) which raised gross proceeds of $10.0 million. Empire distributed at no charge to holders of its common stock, as of the close of business on September 30, 2024 (the record date for the November Rights Offering), one subscription right for each share of common stock held. Each subscription right entitled the holder to purchase 0.063 shares of common stock at a subscription price of $5.05 per share per one whole share of common stock. The subscription rights were non-transferable and not listed for trading on any stock exchange or market. In August 2025, Empire is scheduled to complete a subscription rights offering (the "August Rights Offering”) which is expected to raise gross proceeds of $5.0 million, including $2.5 million to be received upon the future exercise of warrants. Empire distributed at no charge to holders of its common stock, as of the close of business on July 10, 2025 (the record date for the August Rights Offering), one non-transferable subscription right for each whole share of common stock owned by that stockholder on the record date. Each subscription right will entitle a rights holder to purchase one unit at a subscription price equal to $0.07367 per unit, each unit consisting of 0.0139 shares of the Company’s common stock and one rights warrant to purchase 0.0136 shares of the Company’s common stock equal to $5.46 per whole share. The August Rights Offering includes an oversubscription privilege, which entitles stockholders who fully exercise their subscription rights the right to purchase at the same exercise price additional units in the rights offering that other stockholders do not purchase, subject to availability and pro-rata allocation of units among rights holders exercising such oversubscription privilege. No fractional shares of common stock will be issued in the rights offering, including upon exercise of the warrants. The subscription rights were initially set to expire if they were not exercised or extended at the discretion of the Company by July 25, 2025 (the “Expiration Date”). The expiration date was subsequently extended to August 18, 2025 (the “Extension Date”). The warrants will expire 90 days after the extension date of the rights offering.
