Atlantic Union Bankshares (AUB) Q4 2025 earnings review

Merger Integration Clearing, Margins Expanding

Atlantic Union (AUB) closed 2025 with a definitive turnaround quarter. With the heavy lifting of the Sandy Spring integration (systems conversion) now complete, the bank's earnings power is becoming visible. Net Interest Margin (FTE) expanded 13 basis points sequentially to 3.96%—a significant jump driven by falling funding costs. While GAAP earnings remain clouded by $38.6M in merger costs, Adjusted Operating EPS of $0.97 demonstrates the scale benefits of the combined entity. Credit fears from Q3 were quelled as Net Charge-offs dropped to near zero (0.01%).

🐂 Bull Case

Margin Expansion Engine

The rapid drop in deposit costs (Cost of Funds -14bps QoQ) is outpacing yield compression. AUB is successfully leveraging Fed cuts to widen spreads, pushing NIM to a robust 3.96%.

Clean Credit Report

After a scare in Q3 (56 bps net charge-offs), credit metrics normalized immediately. Q4 Net Charge-offs were a negligible 0.01%, and Non-Performing Assets declined to 0.42% of loans.

🐻 Bear Case

Loan Growth vs. Paydowns

While loans grew $435M sequentially, high paydowns are creating a treadmill effect. Deposits actually shrank by ~$193M QoQ, suggesting some liquidity runoff as the bank rationalizes its pricing.

Expense Noise Persists

GAAP results are still heavily burdened by merger costs ($38.6M in Q4). Investors must trust the 'Adjusted' bridge until clean GAAP numbers appear in 2026.

⚖️ Verdict: 🟢

Bullish. The margin expansion is real and powerful. With the integration 'noise' largely in the rearview and credit metrics stabilized, AUB enters 2026 with significantly improved operating leverage.

Key Themes

DRIVER🟢🟢

Margin Expansion (NIM)

Accelerating. Net Interest Margin (FTE) broke out of its holding pattern, jumping from 3.83% in Q3 to 3.96% in Q4. The driver was the liability side: Cost of funds fell 14bps to 2.03% as the bank aggressively lowered deposit pricing following Fed rate cuts, while earning asset yields held relatively steady (down only 1bp).

THEMENEW🟢

Credit Quality Normalization

Reversing. In Q3, two large C&I loans drove net charge-offs to an annualized 0.56%, raising alarms. Q4 data completely reversed this narrative. Net charge-offs fell to $0.9M (0.01% annualized). Non-performing assets (NPAs) also improved, dropping to 0.42% of loans from 0.49% prior.

CONCERN

Deposit Outflows

Decelerating. Total deposits dropped by $193.7M QoQ to $30.5B. While management attributes this to seasonal patterns and the intentional runoff of high-cost/non-relationship deposits from the Sandy Spring acquisition, it limits balance sheet expansion capacity if it continues.

DRIVER🟢

Operating Efficiency (Adjusted)

Accelerating. The adjusted operating efficiency ratio improved to 47.77% in Q4 from 48.79% in Q3. This indicates that the cost synergies from the Sandy Spring deal—specifically the systems conversion completed in October—are beginning to flow through to the bottom line.

Other KPIs

Adjusted Operating EPS$0.97

Accelerating. Up significantly from $0.84 in Q3 and $0.67 in Q4 2024. This metric removes the noise of the $38.6M in merger-related costs and shows the true earnings capacity of the combined bank.

Loans Held for Investment (LHFI)$27.8 Billion

Stable. Grew $435M (1.6% sequential, ~6.3% annualized) driven by CRE and C&I. This is respectable given the general industry headwinds and paydowns mentioned in previous quarters.

Tangible Book Value per Share$19.69

Accelerating. Increased $0.70 per share (+3.7%) from Q3 ($18.99). This accretion is vital for shareholders who suffered dilution during the acquisition phase.

Guidance

Strategic Targets (ROA, ROTCE, Efficiency)Reaffirmed (Qualitative)

Stable. CEO John Asbury stated continued confidence in achieving the strategic goals associated with the Sandy Spring acquisition, specifically referencing targets for Adjusted ROA (previously ~1.50%), Adjusted ROTCE, and efficiency ratio (previously mid-40s). No new specific numerical tables were provided in the release.

Key Questions

Clean Expense Run Rate

With the Sandy Spring systems conversion completed in October and merger costs still at $38M in Q4, what is the 'clean' quarterly non-interest expense run rate expected for Q1 2026?

Deposit Beta Trajectory

Cost of funds dropped 14bps this quarter. As the Fed continues to cut (or pauses), do you have further room to lower deposit rates, particularly in the acquired Sandy Spring portfolio, or have we seen the bulk of the repricing benefit?

Loan Growth vs. Paydowns

Total deposits declined slightly this quarter while loans grew modestly. What is the outlook for funding loan growth in 2026—will you need to tap wholesale funding, or do you expect core deposit growth to resume?

Merger Cost Tail

Q4 saw $38.6M in merger-related costs. How much 'tail' risk remains for these one-time expenses in 2026, or will GAAP and Operating earnings converge in Q1?
