Commerce Bank Lines Up Nolan to Chase Middle-Market Fees

Commerce Bank’s planned Nolan & Associates acquisition puts middle-market M&A advice directly inside its commercial and wealth platform, turning a long-running referral relationship into an owned capability. The Commerce Bank Nolan acquisition, announced Monday, would give the Kansas City-based bank a St. Louis boutique investment bank focused on advisory work for business owners, private equity firms and corporations, according to American Banker.

Financial terms were not disclosed. Commerce did not provide a closing date, and said the transaction remains subject to regulatory approval and customary closing conditions.

Commerce Bank Nolan acquisition adds a middle-market advisory team to a $35.7 billion bank

The core bet is simple: Commerce wants more advisory capability for clients already inside or near its commercial banking network. Commerce Bancshares had $35.7 billion in assets as of March 31, 2026, with commercial offices in 11 states. Nolan & Associates, based in St. Louis, provides sell-side, buy-side and capital raise advice to middle-market clients.

The deal also includes Middle-Market Transactions, Inc., the FINRA-regulated entity through which Nolan delivers advisory services. After closing, Nolan is expected to operate as a wholly owned subsidiary of Commerce Bank. Commerce said in its own release that it intends to retain Nolan’s employees and office, which matters because Nolan’s value is tied to adviser relationships, not just a corporate nameplate.

“We’ve had our sights set on Nolan for quite some time,” Tom Harmon, Commerce’s president of eastern expansion markets and head of commercial tradable products, told American Banker. “We feel really good about this as a strategic fit.”

Commerce says the two firms were already familiar with each other’s clients. Harmon told American Banker that Nolan had previously sold businesses to some of Commerce’s former commercial clients, giving the integration a base of “familiarity, both on the commercial side and with capital for business.”

The strongest counterpoint is size. This is not Commerce’s largest recent transaction. In January, Commerce finalized a $585 million all-stock purchase of FineMark Holdings, a $4 billion-asset private bank and trust company operating in Florida, South Carolina and Arizona. American Banker described that as the largest deal in Commerce’s history and its first under President and CEO John Kemper.

Nolan gives Commerce a sharper pitch to owners nearing sales, succession or capital raises

For Commerce, the strategic value sits at the point where a business owner stops needing only bank products and starts needing transaction advice. Nolan works with business owners, private equity firms and corporations across industries including building products, transportation, logistics, energy, healthcare, telecom, business services, manufacturing, distribution and agriculture, according to Commerce’s release.

That gives Commerce a more specific offer for commercial and wealth clients facing sale processes, acquisitions, ownership transitions or capital raises. The bank’s stated goal is to add “differentiated investment banking capabilities” to its existing commercial and wealth platforms. That language is corporate, but the practical meaning is clear: Commerce wants to be in more conversations before a business changes hands.

Piper Sandler analyst Nathan Race framed the deal as a capability gap-filler, not a near-term earnings event.

“I think this was an opportune acquisition for Commerce … to add full service capabilities to a middle market commercial client base, which includes M&A advisory to help a commercial client, whether it's in the healthcare, hospitality, or any of the other industries Commerce has some specialties in,” Race told American Banker.

Analysis: The Commerce Bank Nolan acquisition should be judged less by purchase price, which remains undisclosed, and more by whether Nolan can pull advisory mandates out of Commerce’s existing relationships. That is the supported thesis in the source material. Race said he believes the bank hopes the acquisition “will be able to drive some incremental advisory revenue in the future.”

The counterpoint is also in the numbers. Investment banking is still a small part of Commerce’s business. The bank reported $5.3 million in capital markets fees between Jan. 1 and March 31, equal to 3.4% of total non-interest income. Race said the transaction is unlikely to affect Commerce’s financial results for “at least the next year or so,” calling it a “pretty small deal in the grand scheme of things.”

For readers tracking other bank business lines, this deal sits in a different lane than XOOMAR’s coverage of BNY USDC custody putting Circle inside bank workflows or real-time payments certainty among bankers. Nolan is about advisory revenue and relationship depth, not custody rails or payment execution.

Retaining Nolan bankers will decide whether the Missouri pairing pays off

The integration test starts with people. Nolan was founded by Pat C. Nolan in 1976 and is described by Commerce as a second-generation, family-owned business with deep Midwestern roots. Commerce also said the acquisition is built on mutual trust and shared client service, and that Nolan will keep its team and office after closing.

That continuity is not a side detail. Nolan’s own president, Patrick Nolan, tied the deal to relationship continuity.

“Joining Commerce is an exciting next chapter for our firm,” Patrick Nolan said. “We’ve built Nolan & Associates on long-term relationships, trusted advice and a strong commitment to our clients and community. Commerce shares those same values and a relationship-driven culture, which made this a natural fit. We’re proud to continue serving our clients with the same team and approach, now backed by the broader capabilities and reach of Commerce.”

The strongest case for the acquisition is geographic and client overlap. Commerce is based in Kansas City. Nolan is based in St. Louis. Harmon said many Nolan clients are in the Midwest, though the firm operates nationwide. He also said there is a “lot of crossover in our respective client bases.”

The strongest risk is that small advisory deals can take time to show measurable results. Race’s “at least the next year or so” caution sets a realistic bar. Commerce can announce broader capabilities immediately, but completed transactions, incremental advisory revenue and wider commercial relationships will have to follow later.

A practical watch item now: Commerce has not said when it expects the deal to close. After regulatory approval and customary closing conditions, the evidence to track will be banker retention, Nolan’s role inside Commerce’s commercial and wealth channels, and whether the Commerce Bank Nolan acquisition turns existing client familiarity into completed advisory mandates.

The Bottom Line

• Commerce is bringing middle-market M&A advisory capabilities directly into its commercial and wealth platform.
• The acquisition turns an existing referral relationship into an owned business line.
• Retaining Nolan’s employees and St. Louis office is central because the firm’s value depends on adviser relationships.
