Following Columbia Banking System’s stronger-than-expected fourth-quarter results, five major sell-side firms revised their 2026 EPS estimates upward by an average of 10%. The consensus now stands at $3.20 per share, up from $2.90 before the release. Analysts cited a surprisingly robust net interest margin expansion and continued loan growth as key drivers, and two firms initiated coverage with “outperform” ratings, signaling increased confidence in the regional lender’s profit outlook.

Columbia Banking System reported total revenue of $320 million for Q4, a 47% increase from $218 million in the year-ago period. Net interest income rose 42% to $250 million, boosted by higher loan yields and deposit repricing, while noninterest income contributed $70 million, up 65% on elevated mortgage banking fees. Provisions for credit losses fell 12% year-over-year to $8 million, reflecting stable asset quality and moderate charge-off levels in its commercial portfolio.

Noninterest expenses increased 15% to $120 million, driven by strategic investments in digital banking platforms and branch upgrades. The efficiency ratio widened to 37.5% from 35.0% a year earlier, but management highlighted disciplined expense control measures that should temper headcount-related costs in 2026. The net interest margin expanded five basis points to 3.12%, exceeding the 3.05% consensus estimate, as management continued to optimize the funding mix between time deposits and wholesale borrowings.
