First Hawaiian is making a bold move off the islands, announcing Monday that it will acquire California-based TriCo Bancshares in an all-stock deal valued at roughly $2 billion. The combination would create a Pacific banking franchise with about $34 billion in assets, according to the two companies, and significantly widen First Hawaiian’s mainland reach while keeping Tri Counties Bank’s name and branch network in place. Under the agreement, TriCo shareholders are set to receive 2.095 First Hawaiian shares for each TriCo share, and executives say they are targeting a closing by the end of 2026, pending regulatory and shareholder approvals. Customers and community leaders in Hawaii and Northern California will be watching how the enlarged bank manages the promised balance between local decision-making and big-bank scale.
As reported by Pacific Business News, the deal would make the combined institution the sixth-largest bank headquartered in the Western United States by assets. That pro-forma scale, at about $34 billion, shifts First Hawaiian from a mostly island-centered player toward a broader Pacific and mainland banking role. Pacific Business News described the agreement as a major mainland step for a bank long identified with its Hawaii footprint.
TriCo Bancshares, the parent company of Tri Counties Bank, is headquartered in Chico, California, and its regulatory filings detail a branch network and loan production offices spread across Northern California and the Central Valley. According to TriCo’s 2025 Form 10-K, the bank operates a mix of stand-alone and in-store locations that serve agricultural communities, suburban areas and smaller metro markets. Executives say that footprint gives First Hawaiian immediate consumer and small-business scale on the mainland, and TriCo’s filings note that this local-market presence is a key reason both sides are pitching the combination as a cultural fit rather than a top-down takeover.
Terms, Leadership and Branding
In a press release posted by First Hawaiian, the bank laid out the deal mechanics: TriCo shareholders will receive 2.095 First Hawaiian shares for each TriCo share, which the companies valued at about $63.12 per TriCo share based on First Hawaiian’s July 10 closing price. “This partnership creates a broader platform for long-term growth,” First Hawaiian Chairman, President and CEO Bob Harrison said in the announcement. The boards of both companies unanimously approved the agreement, and the plan calls for First Hawaiian shareholders to own roughly 65 percent of the combined company, with TriCo shareholders holding about 35 percent at closing. First Hawaiian also told investors it intends to keep the Tri Counties Bank brand on the mainland and does not expect branch closures tied directly to the merger.
Deal Math and Modeled Benefits
Investor slides and transaction disclosures released alongside the announcement spell out the projected financial impact. The materials model about $61 million in pre-tax cost synergies, approximately $125 million in one-time pre-tax merger charges and a $135 million loan credit mark. Taken together, those estimates translate into expected 2027 earnings-per-share accretion of nearly 6 percent and tangible book value dilution of roughly 4.7 percent, with an anticipated earnback period of about 2.8 years. The documents also list Evercore and Sullivan & Cromwell as advisors to First Hawaiian, while Keefe, Bruyette & Woods and Holland & Knight are named as TriCo’s advisors.
What Regulators and Shareholders Will Decide
The companies told investors they plan to file a Registration Statement on Form S-4, which will include a joint proxy statement and prospectus, along with other materials on the SEC’s EDGAR system. The merger is subject to standard regulatory reviews and shareholder votes, and related Form 8-K filings are already available through the SEC’s archives and on the banks’ investor pages. If regulators or shareholders attach conditions or slow the process, the target timeline for closing by the end of 2026 could be pushed back.
Wall Street did not wait for the paperwork. First Hawaiian’s stock traded lower while TriCo shares climbed on the deal premium, according to market coverage. Investing.com reported an early drop of roughly 4.8 percent for First Hawaiian and a jump of about 7 percent for TriCo following the announcement.
