$UMBF · UMB FINANCIAL CORP

October 27, 2026 · AI-analyzed SEC filing

UMB Financial Corporation filed an 8-K announcing a definitive agreement to acquire El Dorado Savings Bank, F.S.B. in a transaction valued at approximately $506 million, structured as 52% cash and 48% stock. El Dorado, headquartered in Placerville, California, operates 35 branches across Northern California and Western Nevada with $2.4 billion in assets and $2.1 billion in deposits. The deal expands UMB's branch network to 227 locations across 15 states and is expected to close in Q1 2027, subject to regulatory approvals and El Dorado shareholder approval.

  • Transaction valued at approximately $506 million, structured as 52% cash and 48% stock.
  • El Dorado brings $2.4 billion in assets, $2.1 billion in total deposits, and $0.5 billion in total loans as of September 30, 2026.
  • Adds 35 branches — 31 in California and 4 in Nevada — expanding UMB's network to 227 branches across 15 states.
  • El Dorado shareholders receive 13.553 UMBF shares plus $1,958.88 cash per El Dorado share; expected to own ~2% of combined company.
  • El Dorado CEO David O. Cook will serve as vice chairman of UMB Bank California post-close.

Extended-hours trading shows UMBF flat at $133.80, indicating no immediate reaction to the deal announcement. The $506M transaction represents roughly 5% of UMB's $10.16B market cap — a modestly sized, bolt-on acquisition unlikely to move the stock materially.

UMB extends its West Coast retail banking push following the 2025 HTLF deal, acquiring a 67-year-old California franchise with a strong deposit base at a manageable ~$506M price tag.

Continues the regional bank consolidation trend, with UMB building on its 2025 HTLF acquisition to deepen its California footprint. The deal adds a low-cost deposit base ($2.1B in deposits against $0.5B in loans) in attractive Western markets.

Integration risk from layering El Dorado onto the 2025 HTLF acquisition; deal requires El Dorado shareholder approval and regulatory approvals, with closing not expected until Q1 2027. Forward-looking statements flag potential failure to realize expected benefits or delays in closing.
