Material Changes vs. Prior Period
- Profitability Growth: Net income increased 37% year-over-year (YTD) to $400 million, driven by the Pacific Premier acquisition and balance sheet optimization. Diluted EPS rose to $1.38 from $1.14.
- Net Interest Income (NII): NII increased $312 million YTD, primarily due to higher average loan balances from the acquisition and a shift toward lower-cost customer deposits. The Net Interest Margin expanded 27 basis points to 3.94%.
- Expense Management: Non-interest expense increased $151 million YTD due to the inclusion of Pacific Premier operations. However, merger and restructuring expenses decreased $15 million quarter-over-quarter as integration activities wound down. A $55 million legal settlement recorded in Q1 2025 did not recur in 2026.
- Balance Sheet Optimization: Total deposits decreased $2.2 billion from year-end 2025, reflecting a deliberate reduction in brokered deposits (down to 2% of total deposits) and seasonal tax payments. Borrowings increased to $4.25 billion, replacing higher-cost brokered deposits with FHLB advances.
- Asset Quality: Non-performing assets rose to $273 million (0.42% of total assets) from $200 million at year-end 2025. This increase is attributed to adverse performance in a single agricultural relationship and is not indicative of broader portfolio deterioration. Net charge-offs were $65 million YTD.
Guidance, Outlook, and Risks
- Capital Actions: The Company repurchased 13.1 million shares for $398 million YTD under a $700 million program authorized in October 2025. $202 million remains available. A quarterly dividend of $0.37 per share was declared.
- Regulatory Capital: The Company remains well-capitalized with a Total Risk-Based Capital ratio of 13.5% and a CET1 ratio of 11.7% as of June 30, 2026.
- Legal Proceedings:
- iCap Entities: The Bank is defending against aiding and abetting claims related to the bankruptcy of 34 real estate investment entities. The District Court denied the Bank's motion to dismiss in June 2026; the Bank has filed for reconsideration.
- MOVEit Data Breach: The Bank is named in multidistrict litigation regarding a third-party vendor security incident affecting approximately 429,000 customers. Management intends to vigorously defend these claims.
- Accounting Changes: In Q2 2026, the Company changed its ACL estimation methodology from a Discounted Cash Flow (DCF) approach to a non-DCF methodology. This change resulted in a net $4 million increase to the ACL.
- Market Risk: The balance sheet remains modestly liability-sensitive. Economic Value of Equity (EVE) analysis indicates a decrease in value in rising rate scenarios and an increase in declining rate scenarios.
Investor Verification Checklist
- Acquisition Integration: Verify the realization of cost synergies from the Pacific Premier acquisition against the $27 million in acquisition-related expenses incurred YTD.
- Asset Quality Concentration: Review the specific exposure to the agricultural industry relationship driving the increase in non-performing assets.
- Legal Exposure: Monitor the status of the iCap Entities litigation and the MOVEit data breach MDL for potential accruals or settlements.
- Funding Mix: Assess the sustainability of replacing brokered deposits with FHLB advances, noting that all current FHLB advances mature in 2026.
- ACL Methodology: Evaluate the long-term impact of the Q2 2026 shift from DCF to non-DCF modeling on future provision volatility.
