<div id="readability-page-1"><article>ATHENS, Greece, Dec. 22, 2025 (GLOBE NEWSWIRE) -- Imperial Petroleum Inc. (Nasdaq: IMPP) (the “Company”), a ship-owning company providing petroleum products, crude oil, and drybulk seaborne transportation services, announced today that at September 30, 2025, pro forma for the Company’s registered equity offering completed on December 1, 2025, the Company’s management estimates Imperial Petroleum Inc’s Net Asset Value (“NAV”) to be $508.03 million. This translates to a NAV of $11.38 per common share currently outstanding and $9.21 per common share on a fully diluted basis (assuming exercise of all outstanding warrants and options for cash), following the equity offering. As of the date hereof, the Company’s largest stockholder, CEO and Chairman, Harry Vafias, directly and indirectly, beneficially owns 13.45 million shares, or 30.1 %, of the outstanding Common Stock, and 200,209 shares, or 25.2%, of the outstanding Series A Cumulative Redeemable Perpetual Preferred Stock, and has not sold a single share since the Company’s inception, reflecting his confidence in the prospects for the Company. NET ASSET VALUE (“NAV”) The estimated NAV is based on estimates of the market value of the vessels in the fleet, investment in C3is Inc., and cash based on the financial statements as of September 30, 2025, pro forma for our equity offering completed on December 1, 2025, less the liquidation value of outstanding preferred shares. The estimated NAV does not reflect our agreements to acquire seven vessels entered into in August and December 2025, including the vessel values and related payment obligations. The estimated NAV represents a snapshot in time, will likely change, and does not represent the amount a stockholder would receive now or in the future for such holder’s shares of the Company’s common stock. This NAV is based on a number of assumptions, estimates and data that are inherently imprecise and susceptible to uncertainty and changes in circumstances. Net Asset Value Calculation methodologies may vary across industries and companies. ABOUT IMPERIAL PETROLEUM INC.
