CONFIDENTIAL-S1 filed

Confidential registration lead

Reuters reported on May 20, 2026 that SB Energy had confidentially filed for a U.S. IPO, which supports a reported confidential submission date of May 20, 2026. SB Energy's own Rule 135 press release the same day said it intended to confidentially submit a draft registration statement on Form S-1, establishing the implied underlying form type but also creating a wording mismatch with the Reuters brief. Follow-on Reuters reporting on May 26, 2026 said SoftBank had hired JPMorgan, Goldman Sachs, Morgan Stanley, Citi, and Mizuho for SB Energy's IPO, that the listing could come as early as September, and that SB Energy could seek a valuation above $50 billion.
