Exhibit 99.3

Guaranty Bank & Trust Employee FAQs

What is happening?

Glacier Bancorp, Inc. (“GBCI” or “Glacier”) signed a definitive agreement to acquire Guaranty Bancshares, Inc. (“GNTY”), the bank holding company for Guaranty Bank & Trust, N.A. (“Guaranty Bank & Trust”), a leading community bank headquartered in Texas. Once the transaction closes, the bank will become Glacier’s 18th bank division, and their first in the state of Texas.

Who is Glacier Bancorp?

Glacier is a bank holding company based in Kalispell, Montana. GBCI is the parent company for Glacier Bank and its 17 bank divisions serving eight states in the Western and Southwestern U.S. Glacier operates with a community banking model, giving local banks autonomy in their markets while sharing the full resources of a larger banking organization. Community banking is central to Glacier’s business model and value system. They believe communities are best served by local division leaders and their teams making decisions about how to best meet the needs of their customers and communities.

Why are we joining Glacier?

Glacier Bancorp is acquiring us to bring together two strong, community-focused companies that share the same values and commitment to local service. Our Board determined that Glacier is a great fit given its focus on buying good banks in good markets with good people. Glacier is a premier acquirer and has a stellar track record of making acquisitions and continuing to build in those markets. At its core, this partnership is about combining strengths to better serve the people and places we care about most.

Glacier currently operates across eight states in the Western and Southwestern U.S., spanning from border to border. The company’s headquarters are in Montana, the fourth largest state in the country. With Texas being the second largest, this move is a natural and complementary extension of the Glacier footprint into our high-growth, diversified economy.

What are the benefits of joining Glacier?

This partnership brings together two banks that believe in the same things: local decision-making, strong community ties, and personalized service. By joining the Glacier family, we’ll have the strength and resources of a larger organization while keeping the local focus our customers value. Customers will benefit from:

 

•

More products and services to meet your financial needs

 

•

Higher lending limits to support your goals

 

•

Continued local service from the people you know and trust

As part of the Glacier family, you’ll continue to have access to great career opportunities and professional growth. Glacier is committed to supporting its employees and offers a very competitive benefits package designed to take care of you and your family.

This combination is about building a stronger future together, and that includes investing in the people who make it possible.

What happens to my job?

Glacier recognizes it’s the people who are behind our success. The majority of positions will be needed as we come together to continue serving customers and growing the business. As we get closer to conversion, there may be some roles that are no longer needed. Management does not expect this to affect a significant number of positions. If any changes occur that affect your role, you can count on clear and timely communication, along with support throughout the process.

What will change for customers?

Right now, nothing is changing. Customers can continue using their current checks, debit cards and online and mobile banking just as they always have. The terms of their loans and lines of credit will stay the same. As we move forward, we’ll keep customers informed well in advance of any changes.

In the long run, joining Glacier means customers will gain access to a wider range of products, services, and tools – all backed by the same friendly, local service they know and trust. We’re confident they’ll be pleased with what’s ahead.

When will the acquisition be complete?

We expect the acquisition will close in the 4^th quarter of 2025 pending approval by banking regulators and GNTY’s shareholders and satisfaction of other closing conditions. The systems conversion is tentatively planned for early 2026.

Will my branch stay open?

Yes.

If I have questions, who can I talk to?

Please share any questions or concerns with your manager, human resources or any member of the leadership team.
