First Financial Bankshares is a $4.6B market cap Texas community bank operating primarily in West/Central Texas. On April 17 it filed an 8-K with Q1 2026 earnings. Headline numbers beat: EPS $0.50 (+16.6% YoY), NIM 3.86% TE (+12bp), efficiency 44.98%. Stock closed +4.88%. The signal is in the credit supplement.

What the filing says

Classified loans moved $255M → $289.7M QoQ, +$34.7M (+13.5%). The Substandard bucket — one step above nonaccrual — drove essentially the entire move: ≈$189M → $222.8M (+$33.8M). Classified/total loans: 3.12% → 3.50%, +38bp in a single quarter, +41bp YoY.

The trailing indicators masked it. NPA/loans improved 0.69% → 0.66%. Net charge-offs: $356K (pristine). Provision: $2.29M (light relative to the classified build). CEO David Bailey, in the lead press release paragraph: "the ongoing Iran conflict" — unusual language for a Texas community banker, absent from the January 29 release. Agriculture loans declined $18.2M QoQ. AFS unrealized loss widened $20M QoQ to $290M (15% of equity).

This is textbook Stage 1→Stage 2 credit migration: accruing loans downgraded into classified status, not yet on nonaccrual, not yet charged off. Historical Stage 2→3 lag is 2-4 quarters.

What the market thinks

FFIN closed +4.88% on the print. RSI 81.9. Regional bank ETF KRE RSI 85.2, +13.0% 1M. TCBI RSI 91.2. PB RSI 79.4. CFR RSI 77.0. The sector is in melt-up mode rewarding headline beats. Only HOMB diverges — RSI 55, -3.9% 1W — after its own April 15 print showed NPL/loans doubled 0.54% → 1.16% on a single $92.1M Texas relationship while ACL was held flat at 1.90% (coverage collapsed 350% → 163%).

CFR trades 14.26x P/E, HOMB 11.07x — the quality spread already reflects some reserve-posture divergence, but the classified migration is not priced in either name. Options on TX community banks are illiquid; equity pair is the expression.

Why the gap exists

Classified loan totals appear in regulatory supplements and earnings footnotes, not press release highlights. Sell-side provision models key off NPA/NCO (trailing), not classified migration (leading). Relationship-concentrated community lending in tertiary Texas is below sell-side resolution — 2-4 analysts per name, no institutional single-borrower modeling. The Iran/Permian oil sensitivity is a tail risk no model prices.

Breadth check matters: we looked for disconfirmation. Regions Financial (Q1 2026) criticized loans -16bp, ACL declining on genuine upgrade activity. M&T criticized -$706M QoQ (5th consecutive decline). Bank7 (Oklahoma energy lender) pristine — zero provision, net recoveries. Dallas Fed Q1 Energy Survey: business activity index -6.2 → +21.0, Permian break-even $67. Not a sector cycle turn. This is Texas CRE non-owner-occupied relationship lending in tertiary markets, with reserve discipline diverging sharply across management teams — CFR building (ACL/NPL 342% → 399%), HOMB releasing (350% → 163%).

Risks (ranked by impact)

1. TCBI Apr 23 clean print. If Texas Capital's criticized bucket is flat or down, the pattern is FFIN/HOMB idiosyncratic rather than Texas-wide. Kills breadth. Sector rips on relief.
2. HOMB single-relationship cure. If the $92.1M nonaccrual has identified collateral with workout path, the Q2 catch-up doesn't materialize. Q1 10-Q Q&A is the read.
3. Fed cut surprise. NIM tailwind offsets classified migration in EPS, buys management time.
4. SLOOS April loosens further. Broader sector credit improvement kills the narrative.

Catalysts

• Apr 23: TCBI Q1 earnings. First confirmation or kill.
• Apr 28 (est): CFR and PB Q1 earnings. Reserve posture read on both legs.
• May 9-12: FFIN 10-Q with energy/CRE NOOCRE segment breakdown.
• Mid-July: HOMB and FFIN Q2 earnings. Payoff print — forced provision catch-up or continued under-reserving.

What would change our mind

• HOMB Q2 provision under $15M (no catch-up) → reserve asymmetry priced, kill short
• FFIN 10-Q shows classified surge concentrated in named, cured relationships → reversal signal
• Two additional non-TX banks show classified surge → was a regional cycle after all, broaden
• Dallas Fed Q2 energy survey rolls over (WTI to $74) with Permian outlook negative → thesis mechanism changes (energy-driven rather than relationship-driven), expand short list
