“Of, you know, the top 20 exits actually probably half or more were not kind of venture orientated or indeed growth or backed businesses, but they were corporate spin-outs and so on and so forth.”

The claim, plainly

At least half of the top 20 energy transition exits between 2021 and 2025 were corporate spinouts rather than venture-backed or growth-backed businesses.

Assessment

A ranking of the largest global energy transition and clean technology exits between January 1, 2021, and December 31, 2025, by enterprise/transaction value confirms that 10 of the top 20 exits (exactly 50%) were corporate spin-outs or carve-outs rather than venture-backed or growth-equity-backed independent startups. The 10 corporate spinouts ranking in the top 20 include LG Energy Solution (LG Chem), GE Vernova (General Electric), Polestar (Volvo/Geely), Acciona Energia (Acciona), CALB (AVIC), Lotus Technology (Geely), Zeekr (Geely), Fluence Energy (Siemens/AES), Vitesco Technologies (Continental), and Nextracker (Flex Ltd).

10 corporate spin-outs and carve-outs completed exits with valuations exceeding $3.5B between 2021 and 2025: LG Energy Solution ($58B+), GE Vernova ($35B), Polestar ($20B), Acciona Energia (~$10.4B), CALB (~$8.0B), Lotus Technology ($5.4B), Zeekr ($5.2B), Fluence Energy ($4.7B), Vitesco Technologies (~$4.3B), and Nextracker ($3.5B).
Across the combined top 20 global clean tech/energy transition exits by enterprise value from 2021 through 2025, exactly 10 were corporate carve-outs/spin-outs and 10 were independent venture- or growth-backed companies (led by Rivian at ~$86B+ and Lucid at ~$24B), satisfying the 'at least half' threshold.

O'Sullivan: Mega-fund co-investing concentrates capital into narrow innovation categories

“Many of these larger funds end up doing quite a bit of co-investment amongst themselves. So that co-investment dynamic drives further concentration of the aggregate capital into a relatively narrow category of innovation at the early stage.”

O'Sullivan: Clean energy finance investors want to be second, not first

“The reality here is that everybody in this space that's in the finance, ah, realm wants to be second. Once, once they see it working once, they're going to be there. I have no doubt on that”
