Pioneer Bancorp's NIM Widens as Acquisitions Crush Efficiency, Capital
Net interest income at Pioneer Bancorp (PBFS) climbed 16.5% to $22.9 million in the second quarter, but four acquisitions closed in the period pushed the efficiency ratio to 78.33% and roughly halved return on equity.
Pioneer Bancorp (PBFS), a community-banking company built increasingly through acquisition, posted its third straight quarter of accelerating net interest income growth, with NII rising 16.5% year over year to $22.9 million in the second quarter of 2026, up from $19.6 million a year earlier and ahead of the 8.7% pace logged in the first quarter. Net interest margin expanded 17 basis points year over year to 4.30%, a wider gain than the 9-basis-point expansion posted in the first quarter or the 4-basis-point move in the third quarter of 2025. The driver was asset repricing rather than deposit relief: asset yields rose 32 basis points in the quarter while funding costs increased just 4 basis points, a marked slowdown from the 16-basis-point funding-cost increase Pioneer absorbed in the third quarter of 2025.
The balance sheet behind that margin expanded sharply. Net loans receivable jumped $224.6 million, or 13.6%, since December 31, 2025, to $1.87 billion, more than quadruple the $54.7 million of growth booked in the first quarter. The Targeted Lending acquisition added $147.4 million in commercial-and-industrial loans, supplemented by $46.2 million of organic residential-mortgage growth and $39.9 million of commercial construction growth, partially offset by a $5.0 million decline in commercial real estate. Deposits grew $229.8 million, or 13.2%, to $1.97 billion, doubling the prior quarter's growth rate, but the composition shifted against the bank: certificates of deposit, largely brokered, accounted for $201.7 million of the increase and money-market balances added $24.7 million, while municipal deposits — the company's traditionally cheaper funding base — fell to 27.0% of the mix from 32.9% in the first quarter.
That growth came at a capital cost. The CET1 and Tier 1 capital ratio fell to 13.22% at June 30 from 17.28% at year-end 2025, and the Tier 1 leverage ratio dropped to 9.97% from 11.93%, as balance-sheet expansion and acquisition-related capital deployment drew down cushion built up over prior quarters. Both ratios remain well above regulatory thresholds for a well-capitalized institution, but the pace of the decline marks a sharp reversal from the capital accretion Pioneer had shown heading into the acquisition spree.
Credit quality sent a mixed signal. Net charge-offs jumped to $1.5 million, or an annualized 0.32% of average loans, from just $70,000, or 0.02%, a year earlier, driven by an $854,000 commercial-and-industrial charge-off alongside newly acquired Targeted Lending losses. The allowance for credit losses rose to 1.48% of loans after a $2.6 million day-one CECL build tied to the acquired Targeted Lending portfolio, even as non-performing assets improved to 0.40% of total assets from 0.52% at year-end. Provision expense actually declined year over year, to $1.4 million from $1.6 million, suggesting management views the legacy book's underlying credit trend as improving even as acquisition-related noise complicates the read-through.
The clearest strain showed up in expenses. Noninterest expense surged 50.6% year over year to $22.2 million from $14.7 million, reflecting professional and legal fees tied to closing four acquisitions in the quarter — Targeted Lending, Reiser Consulting, Wyndham Benefits and College Advisor of NY — plus higher salaries and benefits from acquired headcount, merit increases and elevated litigation expense. The efficiency ratio deteriorated to 78.33% from 60.32% a year earlier, overwhelming the margin gains on the revenue side.
Profitability absorbed the hit directly. Return on assets fell to 0.60% from 1.26% a year earlier, and return on equity fell to 4.29% from 8.23%, reversing the steadier earnings trend of $4.3 million, $3.7 million and $5.3 million in net income posted across the prior three quarters. Noninterest income offered a partial offset, rising 13.7% year over year to $5.5 million on growth in insurance and wealth management — organic plus the Brown Financial Management acquisition closed in the fourth quarter of 2025 — and on new bank fees and gain-on-sale revenue from the Targeted Lending equipment-finance business, a sign the fee-diversification push that began with Brown Financial and the Pioneer Capital Markets broker-dealer launch is starting to show in results.
Pioneer's second quarter reads as two banks moving in opposite directions. The core lending and deposit franchise is repricing well, with NIM expansion accelerating for three straight quarters even as deposit costs stop climbing. The acquisition program layered on top of it is diluting profitability and capital in the near term, pushing efficiency and returns to levels well below the company's year-ago run rate. Whether the four deals closed this quarter pay off will depend on how quickly the acquired fee businesses and loan books integrate without further capital or credit drag.
