Bank mergers are closing faster than ever, and most commercial banks aren’t ready for what that means for their revenue strategy. The time between deal announcement and legal day one is approaching 90 days, a window that fills up quickly with regulatory checklists, core system mapping, and integration planning. By the time business as usual arrives, the commercial opportunity and relationship protection work that should have happened during the merger often hasn’t.
That's the argument Rollie Tillman brought to CONNECT 26, Q2's annual customer conference in Austin. As a principal solutions consultant at Q2 with 27 years in banking and roughly 50 mergers behind him—the vast majority on the acquiring side—Tillman made the case that commercial relationship strategy is among the least discussed dimensions of any M&A transaction, and among the most consequential.
Bank M&A is accelerating. According to S&P Global Market Intelligence, the number of U.S. bank deals grew from 125 in 2024 to more than 180 in 2025, with deal value jumping from $16.3 billion to $49 billion. In 2026, the pattern has shifted. Q1 saw just 35 U.S. bank deals, but those transactions totaled $15.64 billion, a market of fewer, more transformative acquisitions rather than broad-based volume.
The shortening timeline between announcement and legal day one puts more pressure on both acquirers and acquirees to get it right.
“Drama is happening much faster than we thought it was,” Tillman told the audience. “You’ve got to get your plans together in a hurry.”
For most banks, “getting plans together” means grabbing the merger playbook of regulatory checklists, core system mapping, servicing transfer notices, accounting considerations. That work is essential. But Tillman’s point is that it crowds out something equally important: the commercial strategy that determines whether the combined institution emerges stronger or just bigger.
To illustrate the challenge, Tillman sketched a hypothetical scenario familiar to almost anyone in the room. One institution runs a modern, disciplined commercial operation. Relationship managers have good tools, pricing is data-driven, and the bank is executing against a clear strategy. Then comes the acquisition notice. The acquiring bank has grown through deals for years and done well. But it’s running on older processes, a finger-in-the-wind approach to pricing, and a merger playbook that defaults to “come onto our systems.”
The old approach—smash and grab, merge and purge, get back to your day job—was once the industry norm. What he’s seeing more of now are acquirers that treat a merger as a moment to deliberately assess what each bank does well and identify which technologies and processes should carry forward, not just which core survives.
“If you’ve got a better mousetrap and you’re in the bank that’s being acquired, be loud,” he advised. “Talk about the things that you do well. Some of those acquiring banks have really had the desire for the solutions and tools you’ve had.”
What the standard merger playbook rarely tracks is the commercial relationship risk that builds from the moment a deal is announced and keeps building through conversion.
Tillman framed it as a value-at-risk curve mapped against the four milestones of any transaction: announcement, legal day one, conversion day one, and business as usual. The peak of that curve, the point of maximum vulnerability for customer relationships and portfolio alignment, falls squarely in the middle of the deal, between announcement and conversion. Competitors know this. They are, in Tillman’s words, “circling the wagons” the moment a deal goes public, targeting accounts at institutions they know are distracted.
“As soon as the deal is announced, the drama starts internally,” he said. “Everyone’s trying to sort out how they’re going to act as an organization, which people are going to do what, and how do you all come together. That mayhem—everyone in the market knows that, too.”
At the same time, the curve also represents what Tillman calls “opportunity at risk,” the chance to immediately leverage the combined FI’s broader product set, reach new markets, and restructure the portfolio toward stated strategic goals. Most banks defer that work until business as usual. By then, Tillman argues, much of the opportunity has passed.
The reason that opportunity gets deferred is structural. Strategic goals such as attractive markets, portfolio shifts, and EPS commitments travel from the C-suite announcement to the press release and largely stop there. What filters down to the front line is the integration checklist, not the market strategy.
Tillman’s framework identifies three chapters that need to be operationalized in any M&A: go-to-market strategies by geography and business unit; portfolio optimization across the balance sheet and income statement; and retention, growth, and acquisition of targeted commercial relationships. In practice, all three tend to get deferred while the execution machinery of the merger runs its course.
“Sometimes strategy gets relegated to, ‘Once we complete the merger and we get to business as usual, then we’ll start to execute our strategies,’” Tillman said. “That would be the late leadership category, and maybe too late to actually drive those things.”
The antidote isn’t doing less merger execution work. It’s creating a parallel swim lane for commercial strategy that runs concurrently, not sequentially.
Q2 PrecisionLender provides bankers with actionable, in-the-moment insights and coaching so they can structure, price, and negotiate profitable commercial relationships. Business users—not IT teams—configure and manage it, which makes it unusual among the tools that touch commercial deal-making. Relationship managers, treasury officers, and client service managers can use it to price credit and deposit deals, manage account plans, collaborate across deal teams, and track outcomes against portfolio targets.
Because it’s cloud-based and modular, it operates independently of a bank’s core system, which is precisely what makes it relevant during a merger.
Tillman recounted how one bank, in the middle of an acquisition, signed a contract for Q2 PrecisionLender after the announcement, configured the platform to match its capital allocation model and credit philosophy, and had it deployed before legal day one. When the acquired bank came on board, the platform was already live, already calibrated, already in use. “They’re already accustomed to using the platform,” Tillman said. “It became seamless.”
Tillman closed the discussion with a simple directive: Reduce the value at risk. The middle of a merger deal between announcement and conversion is where the most customer and portfolio exposure lives. It’s also where the most opportunity lives. Banks that create space for commercial strategy execution during that window, rather than deferring it, will emerge from deals in a materially better position than those who wait for business as usual.
“Create a little space for the nimble strategy part,” Tillman said, “and choose a partner or technology that allows that to occur and can be changed based on changing needs and strategies.”
With deal timelines approaching 90 days and a market where fewer but more consequential deals are closing faster than ever, there’s no waiting for a better moment.
