First Citizens BancShares, Inc. (NASDAQ:FCNCA), through its First-Citizens Bank & Trust Company subsidiary, completed the acquisition of 138 BMO Bank N.A. branches on September 4. The locations span 11 states across the Midwest, Great Plains and West.

The completion announcement did not disclose final transferred balances. At the announcement, First Citizens BancShares, Inc. (NASDAQ:FCNCA) expected to assume approximately $5.7 billion of deposits and acquire $1.1 billion of loans. Its July 2026 update lowered those estimates to $5.3 billion and $700 million, respectively. Both estimates imply roughly $4.6 billion of net liquidity. That difference represents funding capacity, not transaction income, and remains subject to final balances and acquisition accounting.

The deposit franchise could be the transaction's most valuable asset. At announcement, the acquired deposits carried a weighted average rate of 1.43%, with 21% in noninterest-bearing demand accounts. First Citizens BancShares, Inc. (NASDAQ:FCNCA) reported a 2.07% average total deposit cost in the second quarter of 2026. Retaining the acquired accounts near their original pricing could lower the consolidated funding cost.

The 138 branches also establish or deepen a presence across 11 states. The original transaction presentation identified approximately $1.0 billion of wealth assets under management, creating opportunities to cross-sell commercial lending, treasury services, and wealth products. Retaining branch personnel could help preserve local relationships.

First Citizens BancShares, Inc. (NASDAQ:FCNCA) can deploy the surplus funding in several ways. As of June 30, 2026, the company held $151.03 billion of loans and $32.19 billion of borrowings, including a $28.42 billion purchase money note owed to the Federal Deposit Insurance Corporation. The acquired liquidity could support loan growth, replace more expensive funding, or be invested in securities. The original presentation projected immediate earnings-per-share accretion and an approximately 27-basis-point reduction in the Common Equity Tier 1 capital ratio.

Deposits can move quickly after a conversion. Customers may transfer balances because of pricing, digital-platform differences, branch changes or competing offers. First Citizens BancShares, Inc. (NASDAQ:FCNCA) may need to raise rates or increase marketing spending to prevent attrition, reducing the expected funding advantage.

Deployment also matters. Holding the surplus in cash or lower-yielding securities would generate less revenue than originating well-priced loans. Pushing the funds into loans too quickly could weaken underwriting standards. The acquired loan portfolio was concentrated in commercial and industrial loans and commercial mortgages when the transaction was announced.

The original terms contemplated a premium equal to roughly 5% of acquired deposits. First Citizens BancShares, Inc. (NASDAQ:FCNCA) must also absorb the operating costs of 138 branches while integrating employees, technology, compliance systems, and customer records. The closing release did not provide updated purchase consideration, expense estimates, or synergy targets.

The filings available so far reflect positions held before First Citizens BancShares, Inc. (NASDAQ:FCNCA) completed its acquisition of 138 BMO branches. Insider Monkey's database showed 38 hedge funds holding First Citizens BancShares, Inc. (NASDAQ:FCNCA) at the end of 2Q2026, up from 35 funds three months earlier.

The acquisition gives First Citizens BancShares, Inc. (NASDAQ:FCNCA) a substantial deposit base and broader national footprint. Deposit retention, funding costs, loan growth, debt repayment, and the acquired branch expense base are now the decisive metrics. Durable deposits and disciplined deployment would validate the transaction, while attrition or prolonged low-yield deployment would reduce its value.
