7 SPAC IPOs underwritten · 7 as left lead · 6 active
Santander US Capital Markets LLC, the US investment banking arm of global financial-services group Banco Santander, entered the SPAC underwriting market in 2024 and has since served as left-lead bookrunner on all seven of its transactions. The firm currently carries six active mandates alongside one closed deal, reflecting a concentrated push into blank-check capital markets. Operating across the financial-services sector, Santander US Capital Markets has taken a full left-lead approach on every engagement rather than joining as a co-manager, a posture that distinguishes it from many newer entrants to the SPAC underwriting space.
