Item 8.01 Other Events Equity Distribution Agreement On November 10, 2026, the Company entered into an Equity Distribution Agreement (the “Agreement”) with the sales agents party thereto (collectively, the “Agents”). Pursuant to the terms of the Agreement, the Company may offer and sell up to 50 million shares of common stock, par value $0.25 per share (the “Shares”), from time to time through or to the Agents. Sales of the Shares, if any, will be made by means of ordinary brokers’ transactions or as otherwise agreed between the Company and the Agents as principals. Each Agent will receive from the Company a commission not to exceed 1.5% of the gross sales proceeds of the Shares sold by such Agent. The Company is not obligated to sell any Shares under the Agreement. The offering of the Shares will be registered under the Securities Act of 1933, as amended, pursuant to the Company’s existing shelf registration statement on Form S-3 (File No. 333-284931), which was filed by the Company with the Securities and Exchange Commission (the “SEC”) on February 14, 2025, as supplemented by a prospectus supplement to be filed by the Company with the SEC on November 10, 2026. The Agreement contains customary representations, warranties and agreements of the Company, and customary obligations of the parties and termination provisions. The Agreement is filed as Exhibit 1.1 to this Current Report on Form 8-K, and the foregoing description of the Agreement is qualified in its entirety by reference to such exhibit, which is incorporated herein by reference. Series B Preferred Stock Redemption On November 10, 2026, the Company announced that it has called for redemption all of the outstanding shares of its Series B Cumulative Convertible Preferred Stock, par value $0.25 per share (the “Series B Preferred Stock”). The redemption will occur on December 11, 2026 (the “Redemption Date”) under Section 5 of Annex II to the Company’s Amended and Restated Certificate of Incorporation, which sets out the terms of the Series B Preferred Stock. The redemption price will be $50.00 per share, plus all accrued and unpaid dividends up to the Redemption Date, payable in cash. The Company estimates that accrued and unpaid dividends will be $0.6806 per share, for a total redemption consideration of $50.6806 per share. The Company does not expect to declare another regular quarterly dividend on the Series B Preferred Stock before the Redemption Date. Dividends on the Series B Preferred Stock will cease to accrue on the Redemption Date. Holders may convert their shares of Series B Preferred Stock into shares of the Company’s common stock, par value $0.25 per share, at any time before the close of business on December 10, 2026, the day before the Redemption Date. Each share of Series B Preferred Stock is convertible into 3.2154 shares of common stock, based on a conversion price of $15.55 per share of Series B Preferred Stock, subject to adjustment under the terms of the Series B Preferred Stock. The Company will pay cash instead of any fractional share. Holders who convert will not receive any accrued and unpaid dividend with respect to converted shares. The Company expects to issue any common stock issuable in settlement of any conversions in reliance on Section 3(a)(9) of the Securities Act of 1933. Based on 150,736 shares of Series B Preferred Stock currently outstanding, redeeming all currently outstanding shares would result in the payment of approximately $7.64 million in cash. If all holders of currently outstanding shares were to elect to convert all of their shares of Series B Preferred Stock, the Company would issue approximately 484,700 shares of common stock to settle the conversions. The Company intends to fund the aggregate redemption price with cash on hand. Equiniti Trust Company, LLC will act as redemption agent, paying agent and conversion agent. The Company is mailing a notice of redemption to holders of record on or about the date of this Current Report on Form 8-K. This Current Report on Form 8-K is not a notice of redemption, and it does not constitute an offer to sell or a solicitation of an offer to buy any security. A copy of the Company’s news release announcing the redemption is filed as Exhibit 99.1 and incorporated by reference.
