ABCB vs FBK: Which Is the Better Buy in 2026?
Last updated October 2026
Short answer
ABCB is the larger of the two ($5.35B market cap): the incumbent the market prices for continued execution (11.35x forward earnings, beta 0.97). FBK is the smaller challenger ($2.55B), priced similarly on forward earnings (10.20x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.
ABCB vs FBK: the tie-breaker metrics
Same yardstick, side by side (as of October 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | ABCB | FBK | What it tells you |
|---|---|---|---|
| Market cap | $5.35B | $2.55B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 11.35 | 10.20 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 14.42 | 11.35 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Beta | 0.97 | 0.97 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 44% of range | 17% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 1.30 | 1.32 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Before you buy: how ABCB and FBK affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. ABCB and FBK share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined ABCB and FBK exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does Ameris Bancorp (ABCB) do?
Ameris Bancorp is the holding company for Ameris Bank, a relationship-focused Southeastern regional bank headquartered in Atlanta, Georgia with roots going back to 1971 in Moultrie, Georgia. It operates banking centers across about eight Southeastern states (Georgia, Florida, Alabama, Tennessee, the Carolinas, Virginia, and Maryland), and makes money from commercial and consumer deposits, commercial real estate and residential lending, treasury management, mortgage banking, and other fee-based services. As of late 2025 it managed roughly $27 billion in total assets, with more than $22 billion in deposits and over $21 billion in loans. In 2026 it added a Nashville team and new South Carolina market presidents.
What does FB Financial Corporation (FBK) do?
FB Financial Corporation is the parent of FirstBank, a community and commercial bank headquartered in Nashville, Tennessee, operating branches across Tennessee, Alabama, Georgia, Kentucky, and North Carolina. The bank makes most of its money the traditional way: gathering deposits from consumers and businesses and lending that money out as commercial, commercial real estate, construction, and residential loans, earning the spread (net interest margin) between what it pays on deposits and what it charges on loans. It supplements this with fee income from mortgage banking, wealth management, and deposit services. After completing its acquisition of Southern States Bancshares in July 2025, the combined company reached roughly $16 billion in assets, extending its reach deeper into Alabama and Georgia.
ABCB vs FBK: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- ABCB drivers: Southeast growth footprint; Margin and profitability.
- FBK drivers: Southeastern expansion and M&A; Net interest margin and rate environment.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: As a regional bank, Ameris is sensitive to interest rate swings, which affect both its net interest margin and the value of its securities and deposit franchise, and management has already flagged slight margin compression ahead. For FBK, as a regional bank, FBK is exposed to interest-rate risk: sharp rate moves can squeeze the net interest margin that drives most of its earnings, and the Q3 2026 drop to a 3.83 percent core margin shows that pressure is live.
ABCB or FBK: which should you pick?
Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick ABCB if you believe its drivers more; FBK if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the ABCB and FBK guides.
ABCB vs FBK: the full fundamentals
ABCB. Trailing GAAP earnings are depressed by the Q2 2026 litigation accrual, which is why the trailing P/E (~14.5x) sits well above the forward multiple (~11.4x) built on analysts' ~$7.03 2027 EPS estimate. Consensus for Q3 2026, reported October 22, is about $1.68 per share on roughly $328 million of revenue. At ~1.3x book value and a ~1.0% yield, the shares price in a profitable mid-cap regional bank rather than rapid growth; the average analyst target is about $93.
FBK. As of October 2026, FBK trades around 11.5 times trailing earnings, about 10 times forward earnings and roughly 1.3 times book value, a moderate valuation for a growing Southern regional bank. The Q3 margin dip and revenue miss explain why the shares sit near the bottom of their 52-week range, while the mean analyst target of about $63 assumes margins stabilize. Raymond James trimmed its target to $62 from $65 after the quarter, citing margin pressure.
Headline figures (approximate, October 2026): ABCB shows revenue (ttm) ~$1.18B, revenue growth (latest quarter, yoy) ~3.6%, net income (ttm) ~$376M, diluted eps (ttm / forward) ~$5.53 / ~$7.03; FBK shows revenue (ttm) ~$684M, q3 2026 revenue ~$175.6M vs ~$180.8M estimate, q3 2026 adj. eps $1.21 (in line), net income (ttm) ~$233M.

FAQ
What is the difference between ABCB and FBK?
+
Ameris Bancorp is the holding company for Ameris Bank, a relationship-focused Southeastern regional bank headquartered in Atlanta, Georgia with roots going back to 1971 in Moultrie, Georgia. FB Financial Corporation is the parent of FirstBank, a community and commercial bank headquartered in Nashville, Tennessee, operating branches across Tennessee, Alabama, Georgia, Kentucky, and North Carolina. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is ABCB or FBK the better stock?
+
Neither is universally better. ABCB is the larger incumbent; FBK is the smaller challenger and looks cheaper on forward earnings. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, ABCB or FBK?
+
On forward P/E (as of October 2026), ABCB trades at 11.35x and FBK at 10.20x, so FBK is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both ABCB and FBK?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of ABCB vs FBK?
+
ABCB: As a regional bank, Ameris is sensitive to interest rate swings, which affect both its net interest margin and the value of its securities and deposit franchise, and management has already flagged slight margin compression ahead. A weaker economy or a downturn in Southeastern commercial real estate could raise credit losses well above the current low charge-off levels. Deposit competition from higher-yielding alternatives and fintechs can pressure funding costs and margins; ending deposits dipped in Q2 2026 on quarter-end customer movement. The $82.5 million litigation accrual shows that legal outcomes can swing reported earnings. The bank also faces ongoing regulatory and compliance costs, and its geographic concentration in the Southeast means a regional shock (such as severe hurricanes or a local economic slump) could hit disproportionately. Any acquisition-driven growth carries integration and credit-mark risk. FBK: As a regional bank, FBK is exposed to interest-rate risk: sharp rate moves can squeeze the net interest margin that drives most of its earnings, and the Q3 2026 drop to a 3.83 percent core margin shows that pressure is live. It carries meaningful commercial real estate and construction lending exposure, which can deteriorate quickly in a regional economic downturn or property slump, and a single nonaccrual loan was enough to dent Q3 margin. Mortgage banking income is under pressure from higher rates, which management expects to persist into 2027. Acquisition-led growth adds integration risk, and overpaying or mismanaging a deal can dilute shareholders. Deposit competition and any flight of uninsured deposits (a sector-wide concern since 2023) could raise funding costs. Finally, its concentration in the Southeast means a regional recession would hit it harder than a nationally diversified bank.
