Message from Joe Dively, CEO:
First Mid to Acquire Two Rivers Financial Group, Inc.

First Mid Team -

After years of cultivating a relationship, we are pleased to announce we have entered into a definitive agreement to acquire Two Rivers Financial Group, Inc., the holding company for Two Rivers Bank & Trust. With headquarters in Burlington, IA, Two Rivers Bank & Trust (Two Rivers) operates 14 branches and a loan production office in southeastern and central Iowa. The origin of our relationship spans as far back as 2012, and we are honored that we were chosen as their strategic partner.

Let me pause here. I recognize this news comes at the end of an intense week, as many of us are realizing an important milestone on the core conversion project. I know how much effort, focus, and dedication that project has required thus far, and I want to acknowledge the fatigue that can come after such a major push. The acquisition of Two Rivers is an exciting step forward for our organization, as we expand into a neighboring state, demonstrating our commitment to continued growth and that First Mid remains an attractive merger partner. While this new chapter will eventually bring new opportunities and tasks, please know there will be some time before we begin integrating and planning next steps. For now, we hope you take a moment to reflect on our recent accomplishments and take pride in the role each of you has played and will continue to play in positioning us for this next phase of success. For now, I'd like to share a little more about this growth opportunity and the partner that has chosen us.

While exploring the values of Two Rivers, we gained insight into their authentic culture and commitment to community banking. This merger expands our geographic footprint into Iowa, bringing us to approximately $9 billion in assets. Our branch locations are complementary, and we do not anticipate closing any locations. Many of the Two Rivers branches are less than an hour drive from current First Mid locations. Their focus on relationships in small business, retail, wealth, and commercial areas aligns well with our products and services. We are excited to bring our expanded services and the benefits of a larger balance sheet to the Two Rivers customers.

As of September 30, 2025, Two Rivers had approximately $1.2 billion in total assets, $901 million in loans, and $988 million in deposits. They are publicly traded on OTCQX under the symbol "TRVR". Their roots date back to 1904 when they were known as Burlington Savings Bank, eventually changing their name to Two Rivers Bank & Trust. In 1992, Two Rivers Financial Group, Inc. became the parent company of Two Rivers Bank & Trust. Today they offer financial solutions encompassing banking, trust, and investment management services with locations in Ankeny, Burlington, Coralville, Des Moines, Fort Madison, Keokuk, Mediapolis, Mount Pleasant, Urbandale, West Burlington, and West Point, Iowa.

We anticipate the transaction between the two organizations will close in Q1 2026 and completion of the bank merger and systems conversion will occur in Q2 2026. As information becomes available about the closing and conversion activities, further updates will be provided. We will touch more on the Two Rivers acquisition during the upcoming Quarterly Call on October 31, 2025.
