Atlantic Union Bankshares Corporation (the “Company” or “Atlantic Union”) (NYSE: AUB) reported net income available to common shareholders of $133.7 million and basic and diluted earnings per common share of $0.95 and $0.94, respectively, for the third quarter of 2026 and adjusted operating earnings available to common shareholders⁽⁺⁾ of $135.6 million and adjusted diluted operating earnings per common share⁽⁺⁾ of $0.96 for the third quarter of 2026.

“Atlantic Union delivered a solid third quarter, with healthy loan growth, strong credit quality and continued progress in expanding our earnings capacity,” said John C. Asbury, president and chief executive officer of Atlantic Union. “Excluding the expense associated with the redemption of our subordinated debt, our operating performance demonstrates the earnings power we have built over many years, which we believe positions us to deliver differentiated financial performance relative to our peers.”

“Atlantic Union is a story of transformation from a Virginia community bank into the largest regional bank headquartered in the lower Mid-Atlantic, with operations across Virginia and Maryland and a growing presence in North Carolina. Guided by our priorities of soundness, profitability and growth—in that order—we remain focused on sustainable, profitable growth and long-term value creation for our shareholders.”

STRATEGIC ACTIONS

Subordinated Debt

During the third quarter of 2026, the Company issued $250.0 million in aggregate principal amount of its 6.25% Fixed-to-Floating Rate Subordinated Notes due August 1, 2036 (the “2036 Subordinated Notes”). The 2036 Subordinated Notes convert to a floating rate equal to the three-month term Secured Overnight Financing Rate, plus a spread of 213 basis points on August 1, 2031. Net proceeds from the issuance, after underwriting discounts and offering expenses, were approximately $246.8 million.

The Company used the net proceeds to redeem the $168.0 million principal amount of its outstanding 4.25% Fixed-to-Floating Rate Subordinated Notes due 2029 (the “2029 Subordinated Notes”), plus accrued interest, and for general corporate purposes. The 2029 Subordinated Notes transitioned to a floating interest rate on November 15, 2024, and had a rate of 6.53% at the time of redemption. As a result of the redemption, the Company recognized a $2.7 million pre-tax loss on debt extinguishment in the third quarter of 2026, recorded within non-interest expense, reflecting the acceleration of acquisition-related fair value marks associated with the 2029 Subordinated Notes.

Share Repurchase Program

On May 5, 2026, the Company’s Board of Directors authorized a $250.0 million share repurchase program (the “Repurchase Program”) through May 5, 2027 in open market transactions or privately negotiated transactions, including pursuant to a trading plan in accordance with Rule 10b5-1 and/or Rule 10b-18 under the Securities Exchange Act of 1934, as amended. During the third quarter of 2026, the Company repurchased approximately 1.5 million shares (or $62.5 million), at an average price of $41.38 per share. At September 30, 2026, approximately $177.5 million remained available under the Repurchase Program for future repurchases.

NET INTEREST INCOME

For the third quarter of 2026, net interest income was $328.4 million, an increase of $3.3 million from $325.1 million in the second quarter of 2026. Net interest income - fully taxable equivalent (“FTE”)(+) was $333.1 million in the third quarter of 2026, an increase of $3.4 million from $329.7 million in the second quarter of 2026. The increases from the prior quarter in both net interest income and net interest income (FTE)(+) were driven primarily by higher interest income on loans held for investment (“LHFI”), reflecting loan growth and increased loan accretion income. The aforementioned increases were partially offset by higher deposit interest expense, primarily resulting from increased costs on customer interest-bearing deposits, higher brokered deposit costs, and higher borrowing costs from both short-term and long-term borrowings. Long-term borrowing costs increased primarily due to the overlapping periods in which both the 2029 and 2036 Subordinated Notes were outstanding, as well as the larger principal amount of the 2036 Subordinated Notes.

For the third quarter of 2026, the Company’s net interest margin decreased 7 basis points from the prior quarter to 3.82%. Net interest margin (FTE)⁽⁺⁾ decreased 6 basis points from the prior quarter to 3.88%. The decreases were driven primarily by a higher cost of funds which increased 7 basis points to 2.01% compared to the second quarter of 2026, primarily due to increased costs on interest-bearing customer deposits and higher brokered deposit costs. The yield on total earning assets (FTE)⁽⁺⁾ was 5.89% for the third quarter of 2026, an increase of 1 basis point from the prior quarter, driven by higher loan balances and loan accretion income.

The Company’s net interest margin (FTE)⁽⁺⁾ includes the impact of acquisition accounting fair value adjustments. Net accretion income for the quarter ended September 30, 2026 was $40.9 million, compared to $39.9 million for the quarter ended June 30, 2026. The impact of accretion and amortization for the periods presented is reflected in the following table (dollars in thousands):

ASSET QUALITY

Overview

At September 30, 2026, nonperforming assets (“NPAs”) as a percentage of total LHFI was 0.37%, a decrease of 2 basis points from June 30, 2026 and a decrease of 12 basis points from September 30, 2025, which was primarily driven by lower new nonaccruals in the current quarter. Accruing past due loans as a percentage of total LHFI totaled 0.34% at September 30, 2026, an increase of 6 basis points from June 30, 2026, and an increase of 7 basis points from September 30, 2025. Net charge-offs were 0.03% of total average LHFI (annualized) for the third quarter of 2026, unchanged from the second quarter of 2026, and a decrease of 53 basis points compared to the third quarter of 2025, which was primarily driven by charge-offs of two commercial and industrial loans in the third quarter of 2025. The allowance for credit losses (“ACL”) totaled $334.2 million at September 30, 2026, a $3.3 million increase from the prior quarter.

Nonperforming Assets

The following table shows a summary of NPA balances at the quarters ended (dollars in thousands):

The following table shows the activity in nonaccrual loans for the quarters ended (dollars in thousands):

Past Due Loans

At September 30, 2026, past due loans still accruing interest totaled $98.9 million or 0.34% of total LHFI, compared to $80.4 million or 0.28% of total LHFI at June 30, 2026, and $74.2 million or 0.27% of total LHFI at September 30, 2025. The increase in past due loans from the prior quarter was primarily within commercial real estate – non-owner occupied, commercial and industrial, and commercial real estate – owner occupied loan portfolios.

Allowance for Credit Losses

At September 30, 2026, the ACL was $334.2 million, comprised of an allowance for loan and lease losses (“ALLL”) of $301.4 million and a reserve for unfunded commitments (“RUC”) of $32.8 million. The ACL increased $3.3 million from the prior quarter, primarily reflecting the impact of loan growth during the third quarter of 2026. At September 30, 2026, the ALLL and ACL represented 1.03% and 1.14% of total LHFI, respectively, compared to 1.04% and 1.15% at June 30, 2026. The RUC coverage ratio was 0.11% at September 30, 2026, consistent with the prior quarter.

Net Charge-offs

Net charge-offs were $2.3 million or 0.03% of total average LHFI on an annualized basis for the third quarter of 2026, compared to $2.0 million or 0.03% (annualized) for the second quarter of 2026, and $38.6 million or 0.56% (annualized) for the third quarter of 2025. The decrease in net charge-offs for the third quarter of 2026 compared to the prior year was primarily due to the charge-offs of two commercial and industrial loans that were recorded in the third quarter of 2025 and had been partially reserved for previously.

Provision for Credit Losses

For the third quarter of 2026, the Company recorded a provision for credit losses of $5.7 million, compared to $11.7 million in the prior quarter, and $16.2 million in the third quarter of 2025. The decrease in the provision for credit losses compared to the prior quarter primarily reflected lower reserve requirements associated with a modest decline in the allowance coverage ratio, as well as slower loan growth relative to the second quarter of 2026. The decrease in the provision for credit losses compared to the third quarter of 2025 was primarily attributable to the charge-offs of two commercial and industrial loans that were recorded in the third quarter of 2025 and had been partially reserved for previously.

NONINTEREST INCOME

Noninterest income decreased $35.4 million to $54.8 million for the third quarter of 2026 from $90.2 million in the prior quarter, primarily driven by a $32.3 million pre-tax gain on the sale of the Company’s equity interest in Bearing Insurance Group, LLC (“Bearing Insurance”) recognized during the second quarter of 2026.

Adjusted operating noninterest income⁽⁺⁾, which excludes the pre-tax gain on sale of equity interest in Bearing Insurance ($32.3 million in the second quarter of 2026) and the pre-tax gains on sale of securities ($10 thousand in the third quarter of 2026 and $4 thousand in the second quarter of 2026), decreased $3.1 million to $54.8 million, compared to $57.9 million in the prior quarter. This decrease was primarily due to a $2.0 million decline in loan-related interest rate swap fees driven by lower transaction volumes, a $1.1 million decrease in mortgage banking income due to lower mortgage origination volumes and lower gain on sale margins, and a $1.0 million decrease in fiduciary and asset management fees.

NONINTEREST EXPENSE

Noninterest expense increased $5.2 million to $204.3 million for the third quarter of 2026 from $199.1 million in the prior quarter, primarily driven by the $2.7 million pre-tax loss on debt extinguishment recognized in the third quarter of 2026.

Adjusted operating noninterest expense⁽⁺⁾, which excludes the pre-tax loss on debt extinguishment ($2.7 million in the third quarter of 2026) and amortization of intangible assets ($14.9 million in the third quarter of 2026 and $15.1 million in the second quarter of 2026), increased $2.7 million to $186.7 million, compared to $184.0 million in the prior quarter. This increase was primarily due to a $2.6 million seasonal increase in marketing and advertising expense, a $1.7 million increase in salaries and benefits expense, primarily due to an increase in variable incentive compensation expense and additional full-time equivalent employees associated with the Company’s North Carolina expansion, and a $1.5 million increase in technology and data processing expense, primarily reflecting ongoing investments in strategic technology initiatives and related software maintenance costs. These increases were partially offset by a $3.4 million decrease in other expenses, primarily driven by gains on the sales of other real estate owned during the third quarter of 2026.

INCOME TAXES

The Company’s effective tax rate was 21.1% for the quarter ended September 30, 2026, compared to 20.8% for the quarter ended September 30, 2025. For the nine months ended September 30, 2026 and September 30, 2025, the effective tax rates were 21.1% and 17.2%, respectively. The increase in the effective tax rate for the nine months ended September 30, 2026 was primarily due to a $7.7 million income tax benefit recognized in the second quarter of 2025 related to the re-evaluation of the Company’s state net deferred tax asset following the Sandy Spring acquisition, as well as an overall increase in the proportion of taxable income to tax-exempt income.

KEY BALANCE SHEET COMPONENTS AND CAPITAL RATIOS

The following tables summarize the Company’s key balance sheet components and capital ratios as of the dates presented (dollars in millions, except per share data):

The key drivers of the consolidated balance sheet changes for the periods presented are summarized below:

• Total assets increased from the prior quarter primarily due to increases in LHFI, partially offset by a decrease in cash and cash equivalents. Total assets increased from the same period in the prior year primarily due to an increase in LHFI, partially offset by a decrease in total securities.

• LHFI and quarterly average LHFI increased compared to both June 30, 2026 and September 30, 2025. The increase in LHFI from the prior quarter was primarily due to higher balances in the commercial and industrial, other commercial, and construction and land development loan portfolios. The increase in LHFI from the same period in the prior year was primarily due to increases in commercial and industrial, commercial real estate – non-owner occupied, and other commercial portfolios.

• Total securities decreased from June 30, 2026, primarily reflecting the impact of higher market interest rates on the fair value of AFS securities, with the related unrealized losses reflected in accumulated other comprehensive income (“AOCI”). Total securities decreased from September 30, 2025 primarily due to principal repayments of AFS mortgage-backed securities and the impact of higher market interest rates on the fair value of AFS securities.

• Common equity to total assets and tangible common equity to tangible assets decreased from June 30, 2026, as the negative impact of changes in AOCI associated with higher market interest rates and lower fair values of AFS securities more than offset capital generated through earnings during the quarter.

• Total deposits and quarterly average deposits increased from the prior quarter due to increases in brokered and demand deposits, partially offset by a decrease in interest-bearing customer deposits. Compared to the same period in the prior year, total deposits increased due to higher interest-bearing deposits, partially offset by lower demand deposits.

• Total borrowings decreased from June 30, 2026 and increased from September 30, 2025. The decrease from the prior quarter was primarily due to decreases in Federal Home Loan Bank (“FHLB”) advances, partially offset by an increase in long-term borrowings due to the net impact of the 2036 Subordinated Notes issuance and 2029 Subordinated Notes redemption. The increase from the same period in the prior year was primarily due to increases in FHLB advances and an increase in long-term borrowings due to the Subordinated Notes activity noted above.

• Since the inception of the Repurchase Program authorized on May 5, 2026, the Company has repurchased approximately 1.8 million shares for $72.5 million at an average price of $40.84 per share. As of September 30, 2026, approximately $177.5 million remained available under the Repurchase Program for future share repurchases.
