INNIO Group confirmed it has priced its initial public offering at $27 per share, covering 90 million common shares, the company said. The final size of the offering was increased by 15 million shares from the 75 million originally proposed, representing an upsized secondary sale.
The entire offering represents secondary shares being sold by the sole selling shareholder. According to the company statement, INNIO itself will not be offering any common shares as part of the transaction and will not receive any proceeds from the sale.
Trading of INNIO's common stock is expected to commence on the Nasdaq Global Select Market on June 4, 2026, under the ticker symbol "INIO." The offering is expected to close on June 5, 2026, subject to customary closing conditions, the company said.
The selling shareholder has also granted the underwriters an option to purchase up to an additional 13.5 million common shares at the IPO price, less underwriting discounts and commissions.
Goldman Sachs & Co. LLC, J.P. Morgan and Morgan Stanley are serving as joint lead book-running managers for the offering. BofA Securities, Barclays and Citigroup are acting as book-running managers, with additional bookrunners including Baird, BNP Paribas, Deutsche Bank Securities, RBC Capital Markets and UBS Investment Bank.
The U.S. Securities and Exchange Commission declared the registration statement effective on June 3, 2026.
INNIO is a designer, manufacturer and service provider of power systems marketed under its Jenbacher and Waukesha brands. The company supplies systems intended for a range of applications that include data centers, microgrids, grid stabilization, industrial energy and gas compression. INNIO operates across approximately 100 countries and employs more than 5,000 people worldwide.
This offering is structured so that the selling shareholder, rather than INNIO, realizes the proceeds from the transaction. The underwriters named above will coordinate distribution of the shares and may exercise the additional share option depending on demand and other considerations.
The timetable specified in the company statement sets Nasdaq trading to begin on June 4, 2026, with the formal close of the offering targeted for June 5, 2026, subject to the customary conditions that typically accompany public offerings.
