IPO Status

INNIO Holding GmbH has officially filed for an initial public offering with the SEC. The company is offering 75 million shares at a price range of $24-$27 per share, which would value the IPO at approximately $2 billion at the midpoint. The filing represents a significant step forward from previous IPO speculation to formal SEC registration. INNIO was previously owned by General Electric before being acquired by Advent International in 2018. The company manufactures Jenbacher and Waukesha gas engines used in power generation, oil and gas, and industrial applications. Reports indicate that the IPO timing is being driven in part by the AI data center power boom, which is creating increased demand for flexible power generation solutions.
