OCC approves Santander's merger of Webster Bank, advancing $12.2 billion deal toward 2026 close

The story
The Office of the Comptroller of the Currency has approved Santander's (SAN) proposed merger of Webster Bank (WBS), a critical regulatory milestone on a $12.2 billion transaction first announced earlier. Webster reported strong FY2025 revenue of $2.9B (+11.9% YoY) with a 34.6% net margin and $5.90 diluted EPS, underscoring the franchise value Santander is acquiring. With OCC approval in hand, remaining hurdles are likely limited to Federal Reserve sign-off and any state-level approvals before the anticipated 2026 close.
The key trade setup is the merger-arb spread on WBS: the stock should converge toward deal value as remaining regulatory risk is reduced. The spread's width at current prices reflects residual close-timing risk and any tail risk of Fed non-approval. Watchers should track whether WBS is trading materially below the deal-implied price and how wide that arb remains post-OCC news, as well as any Fed Reserve commentary on bank consolidation.
The case — both sides
OCC approval — historically the hardest hurdle — is now cleared, and WBS's strong FY2025 earnings ($5.90 EPS, 34.6% net margin) give Santander little reason to renegotiate, pointing to spread compression toward deal value.
The Federal Reserve has been increasingly scrutinous of large bank mergers under recent regulatory posture, and any delay pushing the close past 2026 would extend the arb window and increase opportunity cost, keeping the spread wide.
The house read
Leans bullWith OCC approval secured, the question for WBS is how much arb spread remains versus deal value — and whether Fed sign-off or deal timing risk justifies that gap.
Wrong ifFederal Reserve non-approval or material delay past 2026 would widen the spread significantly; any macro shock that causes Santander to invoke a material adverse change clause is the primary tail risk.
