Subject: CT News: Commerce to Acquire FineMark

Commerce Trust Team,

For those unable to attend this morning’s call, I’m excited to share that we announced Commerce has reached an agreement to acquire FineMark, a commercial bank and trust company headquartered in Florida. The deal, which is subject to regulatory approvals and FineMark shareholder approval, is anticipated to close Jan. 1, 2026. John Kemper will send an email to all Commerce team members shortly with more details.

For Commerce, this is more than just an acquisition. It’s a thoughtful, strategic decision that positions both organizations for future growth – growth we couldn’t achieve as easily on our own.

What makes this merger so compelling is how complementary our strengths are. Each company brings something the other needs. FineMark brings energy, innovation, and strong client relationships in markets that are expanding quickly. Commerce adds scale, resources, and depth with capital, operational systems, regulatory experience, and long-term stability.

This combination will allow us to grow in ways we couldn’t before – expanding into new regions, serving more clients, and creating more opportunities for all of us. That includes the chance to work on exciting new projects, grow professionally, and have a bigger impact.

As you may expect, there are still many details to work through regarding next steps and the integration of FineMark into Commerce. We will share additional information along the way.

We’re committed to making this transition smooth and aligned with the values that make both Commerce and FineMark great places to work. We’ll share more details in the days ahead, and we welcome your questions and ideas.

Thank you in advance for your support of this merger and for joining me in welcoming our future colleagues. It’s a bold step ahead for Commerce, and we’re excited about our future.

Best,

John Handy

Commerce Trust Talking Points and FAQs

Overview

About FineMark

FineMark was founded in 2007 in Fort Myers, Florida, and operates 13 banking offices across three states – Florida, Arizona and South Carolina. They currently have 298 associates offering services ranging from personal and business banking to wealth management and more.

Why FineMark?

This is a partnership that will help accelerate profitable growth for both Commerce and FineMark. Each institution brings complementary attributes to the partnership. FineMark benefits from Commerce’s scale, capital, and operational depth. Commerce benefits from FineMark’s access to faster-growing markets and client segments. Both organizations will benefit from sharing incredible talent and collaborating together.

FineMark brings experienced professionals with strong client relationships in high-growth regions, an entrepreneurial culture, and local market insight. Their team has done incredible work building a fast-growing business.

Coming together will result in a bank with combined assets of $36B and more than $82B of wealth assets under administration. Together, we will be the 16th largest bank-managed trust company in the US.

Cultural Alignment

What Will Change?

What’s Next?

More FAQs:

1. How will this affect my job?

No immediate changes are expected to roles or responsibilities. Over time, this partnership will create more opportunities – new markets, new clients, and new ways to develop your career.

2. Will there be layoffs or restructuring?

Our focus is growth, not downsizing. While there may be adjustments in certain overlapping areas over time, the intention is to retain and engage talent across both organizations. However, at a minimum, FineMark associates will continue employment in their same or similar role until systems integrations are completed, which typically takes 12-18 months following closing. As always, continued employment is subject to maintaining performance expectations currently in place.

3. What does Commerce bring to FineMark?

We bring scale, systems, compliance infrastructure, capital, and the stability of a 160+ year institution. Together, we can take FineMark’s success to the next level.

4. How will cultures be integrated?

Both organizations share values like integrity, service excellence and long-term relationships. We’ll work to blend the best of both cultures in a respectful and appropriate way.

5. Will FineMark keep their name?

Once finalized, FineMark is expected to be a division of Commerce Bank, just like Commerce Trust is today. Joe Catti will continue to be CEO of FineMark Bank & Trust (“National” will be removed from their name as they will no longer be regulated by the OCC). Additionally, Joe Catti will become Chairman of Commerce Trust and serve on the Board of Commerce Bank. Joe will report to John Handy, President and CEO Commerce Trust. FineMark associates will become team members of Commerce Bank and will continue to operate under the FineMark brand in their markets, with cobranding opportunities.

6. Are we interested in more acquisitions?

We are always open to strategic partnerships that support our growth in attractive areas of our business. Commerce Trust has a strategic blue chip around growth in new markets and aligning with organizations that fit our business model and culture can be an important part of that growth.

7. When was the last time Commerce completed an acquisition?

Over time, Commerce has experience with dozens of bank acquisitions across our footprint and most recently (June 1, 2023) with the purchase of LJ Hart, a municipal bond underwriter. This particular acquisition is unique, however, in its focus on the wealth business, and it is notable in its size relative to previous transactions.
