Liftoff Mobile Inc., a Blackstone-backed company, raises $437 million in a US initial public offering in its second attempt to go public this year. The offering is priced above the range initially marketed to investors, according to Bloomberg reports. In its trading debut, Liftoff shares open and rise, with reported gains varying by outlet: one report cites a 21% increase, while another notes a 9.1% rise. The company’s IPO follows an earlier effort that did not succeed, and the revived transaction attracts market attention as Liftoff begins trading on US markets. In additional coverage, the company’s CEO, Jeremy Bondy, discusses the IPO and broader business strategy and advertising approach during an appearance on Bloomberg’s “Open Interest.” Across the reports, the consistent elements are the deal size, the above-range pricing, the second-attempt timing, and early share performance after the listing. The sources do not provide additional details on financial results or guidance beyond the IPO terms and trading debut moves.
