First BanCorp. (FBP) Income Statement

The trajectory from -0.1% growth in 2024Q2 through the 8% plateau of 2025 and down to 4.4% implies the repricing benefit that followed the rate-hiking cycle is largely exhausted, leaving loan growth in the auto-heavy consumer book and Commercial segments as the incremental driver. The sequential dip in absolute NII between 2026Q2 and 2026Q3, despite a growing balance sheet, may indicate that funding costs are beginning to catch up with asset yields — a trend investors should monitor given FBP's dependence on a rate-sensitive consumer lending mix. If NII growth continues to converge toward low single digits, total revenue growth will need to be carried by fee lines that have themselves proven volatile.

The stability of NIM at 1.2% against a period of generally easing policy rates appears to reflect a structurally low-cost, relatively captive Puerto Rican deposit base that has so far limited beta — consistent with the company's favorable cost-of-funds position relative to mainland regional peers. However, a flat NIM in a declining rate environment may also suggest loan yields are repricing downward as fast as funding costs, leaving little cushion if the PR deposit market becomes more competitive or wholesale funding needs rise. The plateau matters because with NII representing roughly 70% of total revenue, even a 5-10 basis point NIM decline would materially erode operating income at the current $324M quarterly revenue base.

Total revenue has been range-bound between $318M and $324M for four consecutive quarters while the efficiency ratio has drifted from 48.2% to 50.2%, implying the high fixed-cost branch network is absorbing expense growth that revenue gains are not currently covering. This is a meaningful shift from the 2024-2025 pattern, where the ratio mostly improved from 51.2% toward 47-49%, and it warrants investigation into whether salaries, compliance costs, or Florida expansion spending are driving the step-up. If revenue growth remains in the low single digits while the ratio holds above 50%, pre-provision net revenue growth will decelerate even with benign credit costs.

The moderation from a peak of $24.8M in 2025Q1 to $14.6M has been a direct contributor to operating income resilience, with Q3 operating income of $115.3M holding near record levels despite flat revenue. That said, the decline appears to run against the company's own flagged risk of normalization in auto and consumer delinquencies, so the divergence may reflect a lag in CECL staging rather than a durable improvement in borrower credit quality. A reversal toward the 2025 average of roughly $21M per quarter would absorb approximately 1% of revenue — not catastrophic, but enough to compress net income back toward the mid-$80M range absent offsetting growth.

The extreme dispersion in fee income — the fee share of revenue ranged from 5.4% to 14.9% over ten quarters — indicates a large portion is tied to non-recurring items, most plausibly fair value swings on mortgage servicing rights and mortgage banking activity, rather than stable wealth or transactional streams. The three-quarter decline from 14.9% to 12.8% already represents roughly $5M per quarter of lost non-interest income, which more than offsets the recent improvement in provision expense. Because fees are too small and too volatile to serve as a meaningful hedge against NIM compression, earnings quality remains disproportionately dependent on the spread business.
