Current Project Pipeline Could Deliver Over 100 million Kilowatt Hours (KWh) of Clean Energy to Customers Once Fully Deployed Over Next Two Years, Supporting High-Margin, Long-Term Recurring Revenue Growth

New York, July 1 , 2025 – Alternus Clean Energy Inc (OTCQB: ALCE, ACLEW) (“the Company” or “ALCE”), a transatlantic clean energy provider, announces the filing of its Form 10-Q with the Securities and Exchange Commission, including audited financial results for the first quarter ended March 31, 2025, and provides a business update.

Q1 2025 Financial Highlights

Vincent Browne, CEO of ALCE, commented, “Our efforts to streamline operations and enhance cost efficiency are clearly reflected in our Q1 2025 results. We have reduced selling, general, and administrative expenses by 54% year-over-year to $1.43 million, which is a key metric for us in optimizing capital use. In May 2025, we successfully completed the sale of certain assets which added approximately $13 million in shareholder equity and reduced short-term liabilities and debt by about $18 million.

“Additionally, during the quarter, we invested $1.8 million in targeted microgrid projects in partnership with Hover. We remain focused on scaling efficiently. Our pipeline now exceeds 25 potential microgrid projects on both sides of the Atlantic, which we believe will start to generate recurring revenue and gross margins this year. By the end of 2026, these projects could drive annual recurring revenues to over $20 million.”

“As off-grid and hybrid energy solutions become essential to global energy security, we are excited about the role Alternus is playing in driving the energy transition. Our integrated approach positions us strongly within the rapidly evolving decentralized energy landscape, where our goal is for the traditional grid to increasingly serve as backup power for our client. This is the next major growth frontier in energy, and we are there already,” Mr. Browne concluded.
