(Nasdaq: INIO) today announced a landmark order to supply approximately 1.1 gigawatts (GW) of gas engine capacity to a leading developer and operator of mega-scale data center campuses. The order, one of the largest in INNIO's history, is expected to support the customer’s expanding portfolio of projects and underscores growing demand for reliable and flexible on-site power solutions. “This contract highlights the strong and accelerating demand for independent, on-site power solutions in the data center sector. INNIO is well-positioned to support customers with rapidly deployable power generation solutions that deliver fuel efficiency, reliability, and sustainability. We are powering the AI revolution,” said Dr. Olaf Berlien, President and CEO of INNIO. More than 200 INNIO Jenbacher J624 engines are designed to provide resilient, scalable, and efficient on-site power generation throughout the United States. The capacity is intended to be used entirely for behind-the-meter (BTM) prime power generation. In line with customary confidentiality practices in the data center industry, the developer's name is not disclosed at this time. The 1.1 GW equipment order intake was booked in the second quarter of fiscal year 2026, reflecting strong customer demand and continued momentum in the data center sector. Deliveries are scheduled in phases, providing multi-year revenue visibility. INNIO’s Jenbacher J624 has set the industry standard for high-speed engines in its power class and is well positioned to meet the requirements of data center operators. It offers key advantages over alternative technologies: superior power density, ease of transport, containerization for fast deployment, more stable load-following, and lower redundancy requirements – enabling reliable performance under very demanding AI data center load profiles. INNIO has been recognized multiple times in the past for its commitment to sustainability. The company has received the EcoVadis Platinum Medal for the fifth consecutive year, placing it among the top 1% of all rated companies. Earlier this year, INNIO, together with the Net Zero Innovation Hub for Data Centers, completed a landmark, industry-first demonstration of backup power for data centers using 100% hydrogen-fueled gas engines at the 3 MW scale.  Forward-Looking Statements This press release includes forward-looking statements within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995.
