Atlantic Union Bankshares Corp (AUB) stock intrinsic value fair value estimate & owner earnings analysis

Atlantic Union Bankshares is the largest bank headquartered in Virginia, with $38.1 billion of assets, $30.5 billion of deposits and about 178 branches in Virginia, Maryland, North Carolina and Washington DC. It lends mostly to businesses, much of it against commercial real estate. It has grown by buying neighbouring banks for stock: Xenith in 2018, Access National in 2019, American National in 2024 and Sandy Spring in 2025. Those deals tripled the share count, so per-share earnings went from $1.77 in 2016 to a range of $1.93 to $3.26 since, with no steady upward trend. We value the earnings left for common shareholders after deposit interest and preferred dividends, and we subtract no debt, because for a bank borrowed money is the raw material of the business. Earnings of $2.03 a share in 2025 were held down by about $157 million of Sandy Spring merger costs and an $89.5 million one-time provision on the acquired loans. The first two full quarters of 2026 earned $1.95 a share. Year one of the base case is $3.60. That figure is not growth; it reflects the end of merger costs, confirmed by two quarters of actual results. The key accounting judgement concerns the acquired loans. They were marked down when bought, and the discount is being booked as extra interest income as they repay: about $146 million in 2025, roughly $0.80 a share after tax. This income runs off, so we treat about $0.70 a share as fading roughly 30% a year and value the underlying bank at about $2.90 a share. Base case: underlying earnings grow 1% a year, credited only for repricing a stable loan and deposit base, while the purchase-accounting income runs off. Earnings dip from $3.60 to about $3.16 by year seven and hold there. No future acquisitions are credited, because each deal so far was paid in new shares and did not lift per-share earnings. The base case is worth about $51 a share. Bull case: the announced Sandy Spring cost savings fully land, underlying earnings grow 2% a year, and the shares are worth about $57. Bear case: one full credit cycle like 2008 to 2010 for Southeast and Mid-Atlantic commercial real estate lenders. Commercial real estate is the largest part of the loan book, and the regulatory concentration measure stands at 275% of capital. We assume cumulative loan losses near 6% of loans over three years, with earnings falling to between $0.30 and $0.80 a share and the common dividend cut. Recovery is slow, and normal earnings settle at $2.20 a share, below today, because the purchase income is gone and loan pricing tightens. Losses of that size consume a few years of earnings but leave equity of over $5 billion above regulatory minimums, so we assume no forced share issuance. The bear case is worth about $33 a share. Tangible book is about $20 a share. The bear value exceeds it because even through a downturn the branch network and its low-cost Virginia and Maryland deposits keep earning, as they did in 2020, when earnings held at $1.93. Margin of safety price: $28. We are fairly confident in the earnings level because two clean quarters confirm it. However, the bank is leveraged about 7 times its equity, and a commercial real estate downturn would cut earnings for years. If the purchase income fades faster than we assume and losses run deeper than in 2008 to 2010, the shares are worth about $30. At $28, normal earnings of about $3 a share represent an earnings yield above 10%, and the $1.48 annual dividend represents over 5% over the holding period. Even the bear value sits above that price. From $28, only a move toward the base case over three to four years is needed to imply 20% a year. Previous figures were built on a different basis and are not comparable.
