2026 Annual Meeting April 2026 Glacier National Park, Montana

Forward Looking Statements This presentation contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements include, but are not limited to, statements about Glacier Bancorp, Inc. (the “Company”)’s plans, objectives, expectations and intentions that are not historical facts, and other statements identified by words such as “expects,” “anticipates,” “will,” “intends,” “plans,” “believes,” “should,” “projects,” “seeks,” “estimates” or other comparable words or phrases of a future or forward-looking nature. These forward-looking statements are based on current beliefs and expectations of management and are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are beyond the Company’s control. In addition, these forward-looking statements are based on assumptions that are subject to change. The following factors, among others, could cause actual results to differ materially from the anticipated results (express or implied) or other expectations in the forward-looking statements: 1) Risks associated with lending and potential adverse changes in the credit quality of the Company’s loan portfolio; 2) Changes in monetary and fiscal policies, including interest rate policies of the Federal Reserve Board, which could adversely affect the Company’s net interest income and margin, the fair value of its financial instruments, profitability, and stockholders’ equity; 3) Legislative or regulatory changes, including the possibility of increases in FDIC insurance rates and assessments, changes in the review and regulation of bank mergers, or increases or changes in banking and consumer protection regulations, that may adversely affect the Company’s business and strategies; 4) Risks related to overall economic conditions, including the impact on the economy of an uncertain interest rate environment, inflationary pressures, recently passed legislation and the potential for significant additional changes in economic and trade policies in the current administration; 5) Risks to the Company’s business and the business of the Company’s customers arising from current or future tariffs or other trade restrictions, labor or supply chain issues, change in labor force, or geopolitical instability, including the wars in Iran and Ukraine, further conflicts in the Middle East, and potential for future conflicts or disruptions in other parts of the world; 6) Risks associated with the Company’s ability to negotiate, complete, and successfully integrate acquisitions; 7) Costs or difficulties related to the completion and integration of future or recently completed acquisitions; 8) Impairment of the goodwill recorded by the Company in connection with acquisitions, which may have an adverse impact on earnings and capital; 9) Reduction in demand for banking products and services, whether as a result of changes in customer behavior, economic conditions, banking environment, or competition; 10) Deterioration of the reputation of banks and the financial services industry, which could adversely affect the Company's ability to obtain and maintain customers; 11) Changes in the competitive landscape, including as may result from new market entrants, additional competition from internet-based financial institutions operating nationally, or further consolidation in the financial services industry, resulting in increased competition, including the creation of larger competitors with greater financial resources; 12) Risks presented by public stock market volatility, which could adversely affect the market price of the Company’s common stock and the ability to raise additional capital or grow through acquisitions; 13) Risks related to rapidly evolving artificial intelligence technologies; 14) Risks associated with dependence on the Chief Executive Officer, the senior management team and the Presidents of Glacier Bank’s divisions; 15) Material failure, potential interruption or breach in security of the Company’s systems or changes in technology which could expose the Company to cybersecurity risks, fraud, system failures, or direct liabilities; 16) Risks related to natural disasters, including droughts, fires, floods, earthquakes, pandemics, and other unexpected events; 17) Success in managing risks involved in any of the foregoing; and 18) Effects of any reputational damage to the Company resulting from any of the foregoing. 2

Use and Reconciliation of Non-GAAP Financial Measures Certain financial measures and ratios the Company presents are supplemental measures that are not required by, or are not presented in accordance with, U.S. generally accepted accounting principles (“GAAP”). The Company refers to these financial measures and ratios as “non-GAAP financial measures.” A reconciliation of non-GAAP financial measures to the comparable GAAP financial measures is provided within this presentation. The Company considers the use of select non-GAAP financial measures and ratios to be useful for financial and operational decision making and in evaluating period-to-period comparisons. The Company believes that these non-GAAP financial measures provide meaningful supplemental information regarding the Company’s performance by excluding certain income or intangible items that the Company believes are not indicative of its primary business operating results. These non-GAAP financial measures should not be considered a substitute for financial information presented in accordance with GAAP and investors should not rely on non-GAAP financial measures alone as measures of our performance. The non-GAAP financial measures presented may differ from non- GAAP financial measures used by the Company’s peers or other companies. The Company compensates for these differences by providing the equivalent GAAP measures whenever the Company presents the non-GAAP financial measures and by including a reconciliation of the impact of the components adjusted for in the non-GAAP financial measure so that both measures and the individual components may be considered when analyzing our performance. 3
