The issuer disclosed $150M additional capital and $650M total primary capital raised during calendar 2026. The latter is a period total, not an additional round or all-time cumulative funding. The $870M cumulative amount and $3.75B valuation remain explicitly dated March 3. No new valuation or cumulative total is inferred. Wiwynn invested separately earlier in 2026; its amount and exact investment date were not disclosed.
Investors in the additional $150M are not specifically named. The March Series E participants remain on their dated historical event. Wiwynn's separately disclosed earlier-year investment is not attributed to the $150M.
