Pinnacle Financial Partners announces earnings for first quarter 2026

Diluted earnings per share of $0.89 versus $1.77 in 1Q25

Adjusted diluted earnings per share of $2.39 versus $1.90 in 1Q25

First Quarter 2026 results significantly impacted by merger with Synovus Financial Corp. on January 1

ATLANTA, Ga., April 22, 2026 - Pinnacle Financial Partners, Inc. (NYSE: PNFP) today reported financial results for the quarter ended March 31, 2026. The merger of Pinnacle Financial Partners, Inc. and Synovus Financial Corp. closed on January 1, 2026. The combination creates one of the highest-performing regional banks in the country, positioned for industry-leading revenue, earnings per share and tangible book value growth by marrying Pinnacle’s proven growth model and Synovus’ deep talent and capabilities.

“We set out to scale with a soul, and our first quarter results prove that we’re doing it. We delivered strong loan and deposit growth, expanded revenue and hired 50 new revenue producers, while moving forward with 8,500 team members who never took their eye off the client. The merger was a catalyst for growth rather than a distraction. One quarter in, with much more to prove and deliver, we are confident in the talent, culture and momentum we are building together. The best is still ahead for Pinnacle,” said Pinnacle President and CEO Kevin Blair.

First Quarter 2026 Highlights

•The merger of Pinnacle Financial Partners, Inc. ("Pinnacle" or "legacy Pinnacle") and Synovus Financial Corp. ("Synovus") closed on January 1, 2026. Reported results for Pinnacle reflect the combined organization in first quarter 2026 and legacy Pinnacle in prior periods, unless stated otherwise. Linked-quarter and year-over-year comparisons are significantly impacted by the merger given the magnitude of the acquired balance sheet and the effect of purchase accounting. Prior periods' consolidated financial statements are reclassified whenever necessary to conform to the current periods' presentation.

•Net income available to common shareholders was $134.7 million, or $0.89 per diluted share in first quarter 2026. Excluding merger-related expenses, investment securities gains and a valuation adjustment on certain derivatives, adjusted net income available to common shareholders was $362.7 million, or $2.39 per diluted share.

•Our hiring strategy remains very successful. Pinnacle added 50 experienced revenue producers during the first quarter, compared to 41 for the combined legacy Pinnacle and Synovus in fourth quarter 2025 and 45 for the combined legacy Pinnacle and Synovus in the year ago period.

•Period-end loans were $85.2 billion at March 31, 2026 while period-end deposits were $100.1 billion. Organic loan and deposit growth were substantial in the first quarter.

•Net interest income was $932.7 million in first quarter 2026. On a linked-quarter basis, the net margin expanded 26 basis points to 3.53%, primarily as a result of purchase accounting accretion and fixed-rate asset repricing.

•Non-interest revenue was $284.1 million in first quarter 2026. Excluding investment securities gains and a valuation adjustment on certain derivatives, adjusted non-interest revenue was $281.9 million. Year-over-year non-interest revenue growth from combined legacy Pinnacle-Synovus results was robust, largely attributable to increases in wealth management fees, loan sales and servicing fees and income from our equity method investment in BHG.

•Non-interest expense was $952.2 million in the first quarter 2026. Excluding merger-related expense, non-interest expense was $677.4 million in first quarter 2026. Merger-related expense in first quarter 2026 was $275.4 million, which included merger-related equity acceleration cost. On a combined basis, the non-merger-related linked-quarter increase was driven by higher employment expenses, largely due to seasonally higher personnel costs. The efficiency ratio was 77.4% in first quarter 2026, while the adjusted tangible efficiency ratio was 51.3%. Expense management was disciplined and the majority of the merger-related expense synergies that are expected in 2026 were realized in the first quarter.

•Credit performance remained strong. The non-performing asset ratio was 0.58% at period-end. Non-performing assets were impacted by two senior housing relationships that were previously rated, have a specific allowance and should be resolved this year. The first quarter 2026 net charge-off ratio was 0.23%, which was in line with expectations. Total past due loans were 0.14% of total loans outstanding.

•Provision for credit losses was $75.9 million in the first quarter. The allowance for credit losses ratio (to loans) was 1.19%, while the allowance coverage of non-performing loans was 221% in first quarter 2026. Impacting the allowance for credit losses during the quarter were net loan growth, a

deterioration in the economic forecast and an increase in individually analyzed loans, partially offset by a decline in qualitative reserves.

•The preliminary Common Equity Tier 1 (CET1) ratio ended first quarter 2026 at 9.83%.

(3)Securities are included on an amortized cost basis with yield and net interest margin calculated accordingly.

(4)Includes loans held for sale, trading account assets, and FHLB and Federal Reserve Bank Stock.

(5)As a result of the merger, during the first quarter 2026, certain immaterial changes were made to integrate the presentation of the legacy banks' yield on investment securities, which included presenting average unrealized losses on investment securities available for sale of $(97.9) million as a component of other assets.

(6)The net interest margin is calculated by dividing annualized net interest income-taxable equivalent (TE) by average total interest earning assets.

Non-GAAP Financial Measures

The measures entitled adjusted non-interest revenue, non-interest expense; adjusted revenue taxable equivalent (TE); adjusted tangible efficiency ratio; adjusted pre-provision net revenue (PPNR); adjusted return on average assets; adjusted net income available to common shareholders; adjusted diluted earnings per share; adjusted return on average common equity; return on average tangible common equity; adjusted return on average tangible common equity; tangible common equity ratio; and tangible book value per common share are not measures recognized under GAAP and therefore are considered non-GAAP financial measures. The most comparable GAAP measures to these measures are total non-interest revenue; total non-interest expense; total revenue; efficiency ratio-TE; PPNR; return on average assets; net income available to common shareholders; diluted earnings per share; return on average common equity; the ratio of total shareholders' equity to total assets and book value per common share, respectively.

Management believes that these non-GAAP financial measures provide meaningful additional information about Pinnacle to assist management and investors in evaluating its operating results, financial strength, the performance of its business, and the strength of its capital position. However, these non-GAAP financial measures have inherent limitations as analytical tools and should not be considered in isolation or as a substitute for analyses of operating results or capital position as reported under GAAP. The non-GAAP financial measures should be considered as additional views of the way our financial measures are affected by significant items and other factors, and since they are not required to be uniformly applied, they may not be comparable to other similarly titled measures at other companies. Adjusted non-interest revenue and adjusted revenue (TE) are measures used by management to evaluate non-interest revenue exclusive of net investment securities gains (losses), fair value adjustments on non-qualified deferred compensation and other items not indicative of ongoing operations that could impact period-to-period comparisons. Adjusted non-interest expense and the adjusted tangible efficiency ratio are measures utilized by management to measure the success of expense management initiatives focused on reducing recurring controllable operating costs. Adjusted net income available to common shareholders, adjusted net income per common share, diluted, adjusted return on average assets and adjusted return on average common equity are measures used by management to evaluate operating results exclusive of items that are not indicative of ongoing operations and impact period-to-period comparisons. Adjusted PPNR is used by management to evaluate PPNR exclusive of items that management believes are not indicative of ongoing operations and impact period-to-period comparisons. Return on average tangible common equity and adjusted return on average tangible common equity are measures used by management to compare Pinnacle's performance with other financial institutions because it calculates the return available to common shareholders without the impact of intangible assets and their related amortization, thereby allowing management to evaluate the performance of the business consistently. The tangible common equity ratio is used by stakeholders to assess our capital position. Tangible book value per common share is used by stakeholders to assess our financial stability and value. The computations of these measures are set forth in the tables below.
