Geothermal energy developer Fervo Energy raises $1.89 billion in a US initial public offering, according to multiple outlets. The IPO is priced above the marketed range and the offering size increases before pricing, with sources describing the deal as upsized earlier in the week and again during the process. TechCrunch reports that the IPO is adjusted upward multiple times after potential investors seek details about why the company was not targeting a larger capital raise. In the market debut, Fervo’s shares open and trade up sharply. Bloomberg reports that the stock rises about 33% from the IPO price, with the increase tied to the IPO’s final terms and the larger offering size. Another report also notes a 33% jump in the IPO debut, framing it as investor demand connected to expectations for geothermal power projects, including those supporting data center energy needs. Across the coverage, the main points are the $1.89 billion amount raised, the above-range pricing, the upsizing of the deal, and the roughly one-third share gain on debut.
