VERDICT — CORRECTED ON THE RECORD
INNIO Group, the Munich-based distributed-power-systems maker behind the Jenbacher and Waukesha engine brands, priced an upsized IPO of 90,000,000 shares at $27.00 each on June 3 — the high end of the range and up from an originally proposed 75 million shares — raising about $2.43 billion. Underwriters received a 13.5-million-share over-allotment option. Critically, this is a pure secondary offering: INNIO itself sells no shares and receives no proceeds, with the sole selling shareholder (private-equity owner Advent International) cashing out.
Goldman Sachs, J.P. Morgan and Morgan Stanley were joint lead bookrunners. Shares listed on the Nasdaq Global Select Market under ticker INIO on June 4, opening at $31.00 (up 14.81% from the $27 IPO price) and closing at $33.30, giving the company a market value of roughly $25.5 billion.
The investment thesis is the AI/data-center power crunch: INNIO supplies on-site generation, microgrids and grid-stabilization systems, and its data-center equipment order book surged to ~$1 billion as of March 31 from $309 million a year earlier. The closing expected June 5.
Why it matters
the strong pop validates the 'powering AI' infrastructure trade and marks the third major same-week Nasdaq IPO (with Quantinuum and SpaceX queued), confirming a forcefully reopened IPO market even as energy-driven inflation keeps central banks hawkish.
