INNIO's IPO Makes Gas Engines A Public-Market Power Bet
TL;DR: INNIO priced an upsized $2.43 billion IPO, but the company is not getting the money. The offering is all secondary shares from its selling shareholder, while public investors are buying exposure to gas-engine power systems used in data centers, microgrids, industrial sites, and compression.

A secondary-heavy IPO does something else: it gives existing owners a path to liquidity while public investors take the next leg of valuation risk. That does not make the deal bad. It does make the deal more honest. INNIO is not pitching a blank frontier dream. The prospectus shows 2025 revenue of $2.64 billion, adjusted EBITDA of $549 million, and first-quarter 2026 revenue of $668.6 million. This is an operating company with equipment, service, parts, and a large installed base. But the use-of-pro
