US-based PNC Financial Services Group has signed a definitive agreement to acquire FirstBank Holding Company, which includes its banking subsidiary, FirstBank.
The acquisition will involve approximately 13.9 million shares of PNC common stock and $1.2bn in cash, valuing the transaction at $4.1bn.
FirstBank, which had $26.8bn in assets as of 30 June 2025, offers retail and commercial banking services in Colorado and Arizona, through 95 branches.
In a statement, PNC said the merger will elevate Colorado to one of PNC’s top markets nationwide, tripling PNC’s branch network in the state to 120.
It also hopes to achieve the top position in Denver in terms of retail deposit share (20%) and branch share (14%).
Furthermore, the acquisition will expand PNC’s footprint in Arizona to over 70 branches, with the addition of 13 FirstBank branches.
