Total assets were $65.38 billion at June 30, 2026, down from $66.83 billion at year-end 2025, as loans and leases edged down to $47.17 billion and deposits declined to $52.06 billion, partly offset by higher borrowings of $4.25 billion. The allowance for credit losses was $475 million, slightly below $485 million, after a methodological shift from a discounted cash flow to a non‑DCF approach that added $34 million to quantitative reserves and reduced qualitative components by $30 million. Collateral-dependent loans increased to $237 million, and 0.30% of the portfolio consisted of loans modified for borrowers experiencing financial difficulty. An all-stock acquisition of Pacific Premier valued at $2.4 billion continues to contribute to results, alongside $27 million of acquisition-related expenses year-to-date.
