F.N.B. Trims Its Net Interest Income Guide Again — and the Deposit War It Once Bragged About Winning Is Why

Loans grew 8.5% annualized, buybacks quadrupled and credit stayed pristine, yet the stock sits 9% below its July high: the funding side keeps eating the guidance.

FNB · Earnings Call · 2026-10-20

A good quarter the tape has already discounted

F.N.B. put up $153 million of third-quarter net income, or $0.43 a share, taking year-to-date EPS to $1.23 — a 13% increase over the same stretch of 2025 — on revenue of $469 million and a record $377 million of net interest income. Loans rose at an 8.5% annualized linked-quarter clip to $36.5 billion, ahead of the published H.8 data again, and deposits grew at a 9% annualized rate. Net interest margin expanded four basis points to 3.29%. Tangible book value per share rose 7% year over year to $12.28 — and that was after $51 million of buybacks in the quarter and a negative AOCI mark from rising rates. The market, though, has already had this one. F.N.B. shares peaked at $19.49 on 2026-07-16 and sit 9.4% below that, down 2.5% over the last ninety trading days in a flat chop. After a rerating that took price to book up roughly a quarter year over year to about 1.0x, the incremental buyer needs something new. What they got was a second consecutive cut to net interest income guidance.

The deposit war is the recurring villain

“Full-year net interest income guidance has been revised to a range of $1.485 billion-$1.5 billion, based upon results for the first nine months of 2026 and our expectation for a continuation of heightened deposit competition within the industry.” — Vince Calabrese, Chief Financial Officer · 2026-10-20 This is not a one-off. In July the same guide was trimmed when the second quarter came in “slightly below the guidance range” — Vince Calabrese, Chief Financial Officer · 2026-07-17. Two quarters, two trims, one cause. And the tell is in the mix: after a stretch in which F.N.B. was conspicuously proud of defending funding costs, this quarter the rate paid on interest-bearing deposits went up a basis point. That matters because it breaks a streak management had been trading on. In July the CEO framed it as a differentiator:

We were one of the few banks, I think we're tracking something like 15 banks that have reported so far. I think we're one of three that actually had a lower cost of deposit from the prior quarter.
Vince Delie, Chief Executive Officer · 2026-07-17

Same call, the trade-off was made explicit: “I would prefer to be sub 90, of course, but Alfred can't produce deposits without pricing.” — Vince Delie, Chief Executive Officer · 2026-07-17 The third quarter is that sentence showing up in the numbers. New CDs blended at 3.22% in September — fine relative to the 4.15% headline on the 13-month acquisition product, but the acquisition product is the one that drives deposit growth. The CFO was candid that the prior cycle's ~40% total beta is the right reference point, and there are three hikes in the curve. This is squarely consensus: the reporter list this week is wall-to-wall regional banks saying rate hike, deposit beta, cost of deposit, retail deposits. F.N.B. is not leading a wave here; it is being repriced by one.

Fee income is where the incremental story lives

Non-interest income of $93 million isn't the headline, but the composition is quietly better than the total. Service charges +5.7%, insurance commissions +20%, wealth management +4% to $21 million. Capital markets fell 18% only against a record prior-year comp, and derivative fee income "rolled in the last week or so" after quarter-end — a timing gift for the fourth quarter. The public finance build is producing: F.N.B. won a significant lead-left mandate that closes in Q4, on top of participations already closed. The line about investment banking being "only now starting to make penetration into the customer base" is honest — a first-inning business, but one the company has launched eleven times before, taking fee income from roughly $160 million to about $369 million over fifteen years. The more interesting claim sits in the mortgage book, where a senior executive argues F.N.B. is structurally insulated from the variable that governs everyone else's origination volume:

Our correlation is less than 1%, whereas the mortgage industry is over 97%.
Speaker 8, Senior Executive or Business Leader · 2026-10-20

That is the purchase-money, Physicians First strategy in a sentence — and a number worth interrogating, because a correlation that low is a statement about product mix and borrower cohort, not a hedge. If rates stay higher for longer, the segment still slows; the CEO conceded as much. The real bet is residential mortgage declining as a share of loans from roughly 30% toward 25%, freeing capital for commercial.

CapEx, data centers, and what the tape has stopped paying for

The growth engine on the call is CapEx spend: equipment finance surging on bonus depreciation, manufacturing reviving in Erie and Sharon and central Pennsylvania, C&I up 20% annualized. Buried in that is data centers, which jumped into the company's top-ranked themes this quarter — shipped in with a shrug: "maybe some of it's data centers and a good bit of it is" but "there's a ripple effect." That is the one place where F.N.B.'s enthusiasm collides with the tape. The market's AI data center basket is down 5.5% over both 30 and 90 days; high bandwidth memory is off 7.2%; co-packaged optics down 5.2%. F.N.B. is lending to the steel, electrical and light-manufacturing supply chain of a theme public equities have spent two quarters de-rating. The loans are probably fine — credit is pristine, with net charge-offs of 12 basis points, criticized loans up 40bp but with resolutions booked without loss, and the full-year provision guide trimmed $5 million at the high end to $80-90 million. But “I'm not seeing that as a barrier to CapEx spend, to be honest. The economy seems to be ripping.” — Vince Delie, Chief Executive Officer · 2026-10-20 reads very differently at 1.0x book with the stock 9% off its high than it would have in July.

Capital is now the story, not the footnote

What genuinely changed this quarter is the capital-return cadence. Repurchases hit $47 million in the second quarter and $51 million in the third — $133 million year to date versus $32 million for all of last year — and the buyback activity still left CET1 at 11.3% and TCE at 8.7%. “The stock's lower than it was where we were buying in the third quarter. Clearly there's opportunity to continue to be active on the buyback side.” — Vince Calabrese, Chief Financial Officer · 2026-10-20 is as close to forward guidance as you will get. M&A remains a polite no: "there is not as much as people think out there that is attractive." Two watch items. AOCI cuts both ways — the CFO notes the AOCI-adjusted CET1 exceeds the stated ratio at many peers, but every basis point of drag competes with the buyback for the same capital. And the maturity wall: $500 million of CRE maturities in Q4, $400 million a quarter in 2027, with the CRE book at 182% of Tier 1 plus allowance and management calling for the lines to cross and CRE to grow again in early 2027. The verdict: nothing is broken. Credit is excellent, the fee platform is genuinely diversifying, and the buyback is doing real work. But the two things investors wanted — margin expansion that isn't hostage to deposit pricing, and a stock not already priced for the rerating — both slipped. F.N.B. is a well-run $6.2 billion regional riding a sector-wide funding wave it cannot control, guiding conservatively while insisting the economy is ripping. That tension is the whole trade.
