Insights

M&A Specialist

$476 m all-stock bank merger adds scale; approvals & integration vital.

The 1:1 share exchange keeps Glacier’s capital intact while issuing roughly $476 million in new equity, signalling confidence in its valuation and liquidity. The deal broadens the franchise into attractive Texas markets without cash outlay, but inevitably dilutes existing shareholders and raises cost-of-equity hurdles for expected synergies. Voting agreements from key GNTY insiders reduce execution risk, yet management still must navigate bank-regulator scrutiny and satisfy Community Reinvestment Act criteria. The special dividend carve-out suggests Glacier views interim earnings as belonging to GNTY holders, a modest premium sweetener. Timeline guidance for Q4 2025 appears realistic, but any delay pushes synergy capture into 2026. Investors should track filed S-4 for pro-forma financials, cost-save targets and earn-back period.

Risk Analyst

Regulatory, cultural and system risks could erode forecasted benefits.

Regulators must approve both holding-company and bank-level mergers; recent tightening on regional-bank consolidation could extend review periods or impose divestitures. Glacier flags uncertainties around integrating Guaranty Bank into its existing division structure—often the source of credit and operational risk flare-ups. Forward-looking statements list customer attrition, management distraction and macro variables (rates, competition) as threats, implying that realized ROI may trail pre-deal models. With consideration fixed in stock, market volatility directly affects ultimate value to GNTY holders and dilution to Glacier investors. Monitoring pre-close covenants, especially loan growth and credit quality at GNTY, is critical, as material deterioration could trigger renegotiation or termination clauses.

Item 1.01. Entry into a Material Definitive Agreement.

On June 24, 2025, Glacier Bancorp, Inc., a Montana corporation (“GBCI”), and its wholly owned subsidiary, Glacier Bank, entered into a Plan and Agreement of Merger (the “Merger Agreement”) with Guaranty Bancshares, Inc., a Texas corporation (“GNTY”), and its wholly owned subsidiary, Guaranty Bank & Trust, N.A., a national banking association (“Guaranty Bank”). Under the terms of the Merger Agreement, GNTY will merge with and into GBCI, with GBCI as the surviving entity (the “Holding Company Merger”). Immediately thereafter, Guaranty Bank will merge with and into Glacier Bank, with Glacier Bank surviving as a wholly owned subsidiary of GBCI (the “Bank Merger”).

Concurrently with the execution of the Merger Agreement, the directors and certain executive officers of GNTY entered into voting agreements with GBCI pursuant to which each such director or executive officer, in his, her or its capacity as a shareholder, has agreed, among other things, to vote his, her or its beneficially owned shares of GNTY common stock in favor of the proposed transactions contemplated by the Merger Agreement.

Subject to the terms and conditions of the Merger Agreement, at the date and time when the Holding Company Merger becomes effective (the “Effective Time”), each share of GNTY common stock, par value $1.00 per share, issued and outstanding will be converted into the right to receive from GBCI 1.0000 shares of GBCI common stock, par value $0.01 per share, subject to adjustment as set forth in the Merger Agreement (the “Merger Consideration”).

As of the date of this report, the Merger Consideration has a total aggregate value of approximately $476.2 million, inclusive of the value to GNTY stock options (based on the closing price of $41.58 for GBCI common stock on June 23, 2025).

Under the terms of the Merger Agreement, each outstanding share of restricted stock under the Guaranty Bancshares, Inc. 2015 Equity Incentive Plan, as amended (the “GNTY Stock Plan”), will automatically vest, and each resulting unrestricted share of GNTY common stock will be converted into the right to receive the Merger Consideration at the Effective Time. Each outstanding option to purchase shares of GNTY stock (a “GNTY Option”) granted under the GNTY Stock Plan, whether vested or unvested, will be assumed by GBCI and will be automatically converted into an option (a “Converted Option”) to purchase GBCI common stock on the same terms and conditions as are then in effect with respect to the respective GNTY Option, except that (i) to the extent provided for in the applicable option award agreement, each such Converted Option will become fully vested and exercisable immediately following the Effective Time, (ii) each such Converted Option may only be exercised for shares of GBCI common stock, and (iii) the number of shares of GBCI common stock subject to such Converted Option, and the per-share exercise price, will be adjusted based on the per share Merger Consideration.

The Merger Agreement contains customary representations and warranties from each of GBCI and GNTY, and GNTY has agreed to customary pre-closing covenants, including covenants to operate its business in the ordinary course in all material respects and to refrain from taking certain actions without GBCIs consent, provided that GNTY may, prior to the Holding Company Merger and in an amount determined in accordance with the terms of the Merger Agreement, declare and pay a special cash dividend to its shareholders based on its earnings between March 31, 2025 and closing. In addition, GNTY has agreed to certain additional covenants, including, among others, covenants relating to its obligation to call a meeting of its shareholders to vote on the Merger Agreement, non-solicitation obligations related to alternative acquisition proposals, and, subject to certain exceptions, the obligation of its Board of Directors to recommend that its shareholders approve the Merger Agreement.

Completion of the transaction is subject to required regulatory approvals, GNTY shareholder approval, and other customary conditions of closing. It is anticipated that the closing of the transaction will take place in the fourth quarter of 2025, subject to the fulfillment of customary closing conditions, some of which are described above. The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, which is attached hereto as Exhibit 2.1 and is incorporated herein by reference.
