Filed by The PNC Financial Services Group, Inc. Pursuant to Rule 425 under the Securities Act of 1933 under the Securities Exchange Act of 1934, as amended Subject: The PNC Financial Services Group, Inc. Commission File Number: 001-09718 The following is an article published by S&P Market Intelligence on September 8, 2025, in connection with an interview featuring PNC’s President Mark Wiedman. FirstBank's Colorado scale justified high deal value for PNC, executives say S&P Market Intelligence Staff Writer Tuesday, September 9, 2025, 8:54 PM EDT FirstBank Holding Co.'s scale in Colorado was a key factor behind the premium that PNC Financial Services Group Inc. agreed to pay to acquire the company. The transaction, which would more than triple PNC's current Colorado branch network to 120, has a deal value of $4.1 billion, or roughly 2.3x FirstBank's tangible book value, making it the most expensive bank deal of 2025 so far, according to S&P Global Market Intelligence data. The transaction's deal value-to-tangible common equity ratio is 234.15%, the highest of the year on US bank M&A transactions. Colorado is already one of PNC's top target markets for organic growth, and acquiring FirstBank is PNC's only path to gaining significant scale in the state on an accelerated timeline, PNC President Mark Wiedman said in an interview. "This was a unique natural resource; the only mountain pass we could go through," Wiedman said. "If you're the only mountain pass, you can charge more for people coming through." Continuing to grow without expanding into new markets would likely prove difficult for PNC, and population growth in Colorado has been "phenomenal," so it makes sense for the company to expand its presence in the state, McQueen Financial Advisors Founder and CEO Charley McQueen said. "They've got to get to a new regional area to continue to grow," McQueen said. "They've got a bit of the Midwest and Southeast covered. This is a great way to get to the middle part of the country." FirstBank was PNC's only path into Colorado because the company is the only bank of scale in the state, aside from large, out-of-state national banks, FirstBank President and CEO Kevin Classen said. The company had $26.8 billion in assets and was the only Colorado-based bank with more than $10 billion in assets as of June 30, according to S&P Global Market Intelligence data. "It is hard to find scale, and in Colorado ... how you do it would be to come through us," Classen said. "I think it was of strategic importance to them as they moved West, and I think that's why they were willing to pay for it." Loans and deposits FirstBank's "excellent" deposit franchise and substantial lending relationships in the state were also driving factors behind the deal's pricing, Wiedman said. The company's branch network is better than what PNC would have been able to build over time organically, with a stable funding base of retail deposits, he said. First Bank's cost of funds, at 1.58% as of June 30


 
according to Market Intelligence data, is also significantly lower than the effective Fed Funds rate of 4.33% as of Sept. 8. On the lending side, FirstBank's portfolio is lower-risk, with 47% of the company's loans in residential one-to- four-family mortgages and 40% in commercial real estate, Janney analyst Christopher Marinac wrote in a Sept. 8 research note. The transaction will make Colorado one of PNC's top commercial banking markets in the country and grow the company's retail lending portfolio in the state, Wiedman said. "Both on the asset and liability side, this is a pretty good franchise," Wiedman said. "Call it a gem. That justified a nice premium for the sellers. They built a great bank." Argus Research analyst Stephen Biggar said the benefits that FirstBank will provide to PNC, including the increased Colorado market share, justify the price. "It did not strike me that they were overpaying, necessarily, considering the benefits that they'll be getting out of it," Biggar said. Looking ahead Regarding future M&A opportunities, Wiedman described the FirstBank acquisition as "one step in a long journey," and said the company will continue to look for opportunities as it aims to build a coast-to-coast national bank. "We're open to a wide range of paths," Wiedman said. "Our main thrust is organic growth, but opportunistically, if we can jump a year or two in our planning, we take it."
