Popular heads into its third-quarter report with an odd disconnect. Last quarter the Puerto Rico lender delivered record profitability, raised its net interest income outlook for the second time this year, lifted its long-term return target, boosted the dividend 20% and authorized a fresh $1 billion buyback. The stock has fallen 11% since then, while the S&P 500 rose about 5%. The October 22 release, due before the open, is also the first under Jorge Garcia, who moved from CFO to chief executive when Javier Ferrer retired at the end of August. It has to show that the stronger earnings story holds up and that the credit problems flagged in the summer are isolated rather than spreading.

The Street expects earnings of $3.89 a share, up almost 24% from $3.14 a year ago but below the $4.35 posted last quarter. That sequential step down looks sensible. Second-quarter results got help from $181 million of non-interest income, well above the $160 million to $165 million quarterly run rate management has long guided to. A lower expected tax rate of 14% to 15% also flattered the bottom line. Consensus revenue of $872.1 million implies a 23% year-over-year decline. That figure appears to rest on a different revenue basis than prior reported totals. It sits awkwardly beside a full-year guide calling for 8% to 9% growth in net interest income, so the NII line is the better gauge of momentum.

That NII trajectory is the core of the bull case. Management widened its growth outlook from 5% to 7% at the start of the year to the upper end of that range, then to 8% to 9%. A third quarter consistent with that pace would confirm the raise was grounded in asset repricing rather than optimism. The constraint is margin. Management now expects net interest margin to be only stable for the rest of the year, not expanding. Two forces are absorbing the benefit: a larger and costlier pool of Puerto Rico public deposits, with the target lifted to $20 billion to $22 billion, and widening basis risk tied to three-month Treasury rates. Margin slippage, or a sharp jump in deposit costs, would challenge the idea that returns can keep climbing. Loan growth matters too. It is running at the low end of a 3% to 4% range, down from about 6% last year, as large Puerto Rico deals thinned and US construction loans paid off. Any sign that the island's reshoring investment and tourism strength are turning into commercial loan demand would be welcome.

Credit is the swing factor and the likeliest reason for the stock's retreat. Management raised its full-year net charge-off guide to 65 to 80 basis points after a $71 million write-off on a long-troubled telecom loan. It also placed two unrelated commercial relationships totaling about $129 million on non-accrual. Excluding the telecom item, charge-offs ran a benign 33 basis points, and consumer and mortgage credit kept improving. The key question is whether those two new non-accruals resolve with limited losses or bring new problem names with them. Quarterly charge-offs that keep the full-year figure comfortably inside the raised range would support management's view that these were discrete events. New non-performing commercial loans would undercut it.

Sentiment has cooled, with bullish readings slipping to about 38% from 47% before the last report. The shares sit at $155.82, just 2% above their post-earnings low of $152.43 and only slightly above the 200-day moving average of $151.21. The bar has come down even as reported fundamentals improved. With the buyback likely active at these prices, steady credit could let the earnings story reassert itself. In the end, the report turns on whether the 17% return on tangible common equity looks repeatable under new leadership, or whether commercial credit begins to erode it.
