FB Financial Corporation has spent four years converting a $14 billion-asset community bank into a $16.8 billion-asset southeastern regional, and the second-quarter 2026 results suggest the strategy is now compounding rather than absorbing. The July 1, 2025 acquisition of Southern States Bancshares added $2.83 billion in assets, $2.27 billion in loans, and $2.47 billion in deposits in a single transaction, lifting the holding company's loan book by roughly 24% and pushing net interest income to $149.0 million for the quarter, up 33.7% from $111.4 million a year earlier. The tax-equivalent net interest margin expanded 27 basis points to 3.95%, return on average assets reached 1.44%, and diluted earnings per share of $1.13 nearly twenty-folded the $0.06 reported in the second quarter of 2025, which had been weighed down by a $60.5 million loss on the sale of available-for-sale debt securities.
The operating story underneath the headline is more important than the deal. Loan growth of roughly 6% on a pro-forma basis, deposit repricing that cut the cost of interest-bearing deposits to 2.81% from 3.10% a year ago, and credit quality that has held inside historical ranges even as the loan portfolio absorbed an acquired book of mostly Alabama and Georgia exposures, all suggest the integration is tracking. Nonperforming assets at 1.14% of total assets remain well below industry stress levels, the Common Equity Tier 1 ratio sits at 11.0%, and tangible book value continues to grow at a measured pace. Management's June 30, 2026 quarter produced $58.6 million in net income and a 14.6% return on average tangible common equity, the kind of return that few sub-$20 billion community banks can sustain.
The single most important variable to watch is nonperforming loan formation. NPAs climbed to $192.3 million at quarter end from $158.1 million at year-end 2025, with one large commercial and industrial relationship and one commercial real estate relationship moving into nonaccrual during the period. The allowance for credit losses of $194.0 million covers nonperforming loans HFI 1.29 times, but the absolute level of inflow is the swing factor for the next several quarters. If the migration does not extend further, the combination of mid-single-digit organic loan growth, accretive purchase accounting, and active capital return makes the case for the stock. If it does, the cushion narrows quickly. With the shares trading at roughly 11 times forward earnings and 1.5 times tangible book, valuation offers some protection, but the question is operating, not multiple.
