Innio on Tuesday disclosed plans for a U.S. initial public offering that would place its market value as high as $20.25 billion. The Munich, Germany-based maker of gas engines said its principal shareholder, AI Alpine - co-owned by funds managed by Advent International and the Abu Dhabi Investment Authority - intends to sell 75 million shares in the offering, with a proposed price range of $24 to $27 per share and a target raise of as much as $2.03 billion.
The filing highlights a shift in investor focus toward the suppliers that support the expansion of artificial intelligence infrastructure. As market participants weigh AI's potential to reshape industries, attention has moved to the "picks and shovels" of the buildout - from electrification projects to the supply chains that underpin data centre construction and operation. Innio positions itself within that supply chain by manufacturing gas engines sold under the Jenbacher and Waukesha brands, components the company says are used in critical infrastructure including data centres.
Innio reported a pronounced rise in demand from data centre customers, with annual orders for data centre equipment expanding roughly 16-fold between 2020 and 2025. That growth is cited in the company's filing as a driver of its recent performance and a rationale for pursuing a public listing in the United States.
The company traces its modern form to a 2018 transaction in which U.S. buyout firm Advent International carved General Electric's distributed power business out to create Innio as an independent company in a deal valued at $3.25 billion. In 2023, the Abu Dhabi Investment Authority took a minority stake in the firm. Under Advent's stewardship, Innio has increased its presence in North America, making investments to expand U.S. manufacturing and assembly capacity.
Goldman Sachs, J.P. Morgan and Morgan Stanley are named as joint lead book-running managers for the offering. Innio plans to list on the Nasdaq exchange under the ticker symbol "INIO."
The filing frames the IPO as a way for the company's controlling shareholder to monetize part of its stake while signalling Innio's role as a supplier to the energy and data centre segments that have seen higher electricity demand tied to the AI-related buildout. The document does not forecast outcomes or provide forward-looking guidance beyond the proposed share count and pricing range.
Sector impacts: The planned listing touches the energy equipment and industrial manufacturing sectors and relates to the data centre supply chain that supports AI infrastructure.
