Weather and security platform Tomorrow.io will go public through a merger with a blank-check firm in a deal worth nearly $1.2 billion, the companies said on Tuesday. The deal with special purpose acquisition company (SPAC) Pine Technology Acquisition Corp (PTOC.O), which is expected to close in the first half of 2022, will fetch up to $420 million in proceeds for Tomorrow.io. Proceeds will be invested in Tomorrow.io"s platform, used to launch radar-equipped satellites and for some "strategic M&A", said Chief Executive Shimon Elkabetz. Tomorrow.io is used by customers including JetBlue Airways Corp (JBLU.O) and Uber Technologies Inc (UBER.N) to predict the impact of weather events. Formerly known as ClimaCell, the company was founded in 2016 by Elkabetz, Rei Goffer and Itai Zlotnik - all former members of Israeli armed forces. Elkabetz said weather forecasting technology was currently dominated by the government, but added it was "impossible for it to stay this way". "So we saw the opportunity to really become the SpaceX of weather," Elkabetz said. Funds managed by Koch Strategic Platforms, National Grid Partners, JetBlue Technology Ventures, SoftBank Group"s (9984.T) subsidiary SB Energy Corp and others are also participating in a $75 million private investment in public equity (PIPE). A SPAC is a listed pool of capital with no business operations except hunting for a private company to merge with, in a deal that then takes the private company public. After a bumper 2020, the SPAC dealmaking frenzy fizzled out this year with tightening scrutiny from the U.S. Securities and Exchange Commission and saturated demand. Boston-based Tomorrow.io will list on Nasdaq under the symbol "TMW". Reporting by Niket Nishant in Bengaluru; editing by Jane Wardell Our Standards: The Thomson Reuters Trust Principles.
