Round amount basis
Exact as disclosedEquity
The June release first disclosed the recently completed $150M Series B2 but gave no separate closing date, so its disclosure date is used. The SGD 100M debt facility and optional USD 75M upsize are excluded from equity funding; the valuation remains the dated July 2025 figure.
The source did not name Series B2 equity participants. Ares, InnoVen, January Capital Growth Credit, and Abound Capital are separately disclosed debt lenders, not B2 investors.
