Western Alliance Bancorporation Reports Third Quarter 2026 Financial Results

PHOENIX--(BUSINESS WIRE)-- Western Alliance Bancorporation (NYSE:WAL): THIRD QUARTER 2026 FINANCIAL RESULTS Quarter Highlights: Net income Diluted earnings per share PPNR 1 Net interest margin Efficiency ratio 1 Book value per common share $277.2 million $2.45 $419.1 million 3.57% 58.1% $68.14 50.0%, adjusted for deposit costs 1 $62.22, excluding goodwill and intangibles 1 CEO COMMENTARY: “Western Alliance’s third quarter results featured enhanced profitability, lower deposit costs, improved asset quality and stronger reserve coverage, as well as accelerated share repurchase activity,” said Kenneth A. Vecchione, Chairman, President and Chief Executive Officer. “Strong execution generated pre-provision net revenue 1 of $419 million, up $25 million, or 6.4%, year-over-year and earnings per share of $2.45, up $0.17, or 7.5%. Return on average assets of 1.12% and return on average tangible common equity 1 of 15.5% both increased for the second consecutive quarter. Deposit optimization actions totaling $4.5 billion over the past two quarters drove a $14 million, or 8%, quarterly decline in ECR-related deposit costs. Strong commercial banking deposit growth offset the optimization activity, keeping total deposits stable at $81.8 billion. Net interest income increased $11 million from the prior quarter, while net interest margin expanded 4 basis points quarterly to 3.57%. Asset quality improved notably, with nonaccrual loans declining $77 million, or approximately 14%, to 0.79% of funded HFI loans. Continued reserve building increased ACL coverage of funded HFI loans by 4 basis points to 0.93% and raised ACL coverage of nonaccrual loans from 96% to 118%. Net charge-offs declined 7 basis points quarterly to 0.30%, the midpoint of our 2026 guidance range. We continued to prioritize shareholder returns, repurchasing $92 million of shares.” LINKED-QUARTER BASIS YEAR-OVER-YEAR FINANCIAL HIGHLIGHTS: Net income of $277.2 million and earnings per share of $2.45, up 3.1% and 3.8%, from $268.8 million and $2.36, respectively Net revenue of $1.0 billion, increased 1.9%, or $18.5 million, from $995.7 million Pre-provision net revenue 1 of $419.1 million, up $6.7 million, or 1.6%, from $412.4 million Effective tax rate of 18.3%, compared to 19.0% Repurchased $92.1 million, or 1.15 million shares at an average price of $79.78 per share Net income of $277.2 million and earnings per share of $2.45, up 6.4% and 7.5%, from $260.5 million and $2.28, respectively Net revenue of $1.0 billion, increased 8.1%, or $76.0 million, from $938.2 million Pre-provision net revenue 1 of $419.1 million, up $25.3 million, or 6.4%, from $393.8 million Effective tax rate of 18.3%, compared to 17.0% FINANCIAL POSITION RESULTS: HFI loans of $61.5 billion, up $600 million, or 1.0% Total deposits of $81.8 billion, down $119 million, or 0.1% HFI loan-to-deposit ratio of 75.3%, up from 74.4% Total equity of $7.9 billion, down $188 million, or 2.3% Increase in HFI loans of $4.9 billion, or 8.7% Increase in total deposits of $4.5 billion, or 5.8% HFI loan-to-deposit ratio of 75.3%, up from 73.3% Increase in total equity of $257 million, or 3.3% LOANS AND ASSET QUALITY: Nonaccrual loans to funded HFI loans of 0.79%, decreased from 0.92% Nonaccrual loans and repossessed assets to total assets of 0.66%, decreased from 0.70% Allowance for credit losses to funded HFI loans of 0.93%, increased 4 basis points from 0.89% Allowance for credit losses to nonaccrual loans of 118%, increased 22% from 96% Annualized net loan charge-offs to average loans outstanding of 0.30%, compared to 0.37% Nonaccrual loans to funded HFI loans of 0.79%, decreased from 0.92% Nonaccrual loans and repossessed assets to total assets of 0.66%, decreased from 0.72% Allowance for credit losses to funded HFI loans of 0.93%, increased 8 basis points from 0.85% Allowance for credit losses to nonaccrual loans of 118%, increased 26% from 92% Annualized net loan charge-offs to average loans outstanding of 0.30%, compared to 0.22% KEY PERFORMANCE METRICS: Net interest margin of 3.57%, increased from 3.53% Return on average assets and on tangible common equity 1 of 1.12% and 15.5%, compared to 1.09% and 15.3%, respectively Tangible common equity ratio 1 of 6.9%, decreased from 7.0% CET1 ratio of 10.9%, compared to 11.0% Tangible book value per share 1 , net of tax, of $62.22, decreased 1.6% from $63.24 Efficiency ratio 1 of 58.1%, increased 0.1%, from 58.0%, while the efficiency ratio, adjusted for deposit costs 1 increased 1.1% to 50.0% from 48.9% Net interest margin of 3.57%, increased from 3.53% Return on average assets and on tangible common equity 1 of 1.12% and 15.5%, compared to 1.13% and 15.6%, respectively Tangible common equity ratio 1 of 6.9%, decreased from 7.1% CET1 ratio of 10.9%, compared to 11.3% Tangible book value per share 1 , net of tax, of $62.22, increased 6.3% from $58.56 Efficiency ratio 1 of 58.1%, increased 0.7%, from 57.4%, while the efficiency ratio, adjusted for deposit costs 1 increased 2.2% to 50.0% from 47.8% 1 See Reconciliation of Non-GAAP Financial Measures. Income Statement Net interest income totaled $807.6 million in the third quarter 2026, an increase of $10.7 million, or 1.3%, from $796.9 million in the second quarter 2026, and an increase of $57.2 million, or 7.6%, compared to $750.4 million in the third quarter 2025. The increase from the second quarter 2026 was primarily due to higher yields on interest earning assets and higher average HFI loan balances, partially offset by lower average balances in cash and other interest earning assets and an increase in average interest bearing liabilities and the related costs of these liabilities. The increase in net interest income from the third quarter 2025 was primarily driven by an increase in average interest earning asset balances of $5.5 billion and lower rates on interest bearing liabilities, partially offset by declining yields on interest earning assets. The Company recorded a provision for credit losses of $80.0 million in the third quarter 2026, compared with $80.4 million in the second quarter 2026, and $80.0 million in the third quarter 2025. The provision for credit losses during the third quarter 2026 was primarily driven by net charge-offs totaling $45.8 million, loan growth, and proactive provisioning for macroeconomic risks associated with the higher interest rate environment. These factors increased the total allowance for credit losses to funded HFI loans ratio from 89 basis points in the prior quarter to 93 basis points. The Company’s net interest margin increased to 3.57% in the third quarter 2026 from 3.53% in both the second quarter 2026 and the third quarter 2025. Net interest margin increased from the second quarter 2026 due to higher yields on interest earning assets, partially offset by higher costs on interest bearing liabilities. Net interest margin increased from the third quarter 2025 as an increase of $5.5 billion in average interest earning assets and lower interest bearing liability costs more than offset declining yields on interest earning assets. Non-interest income was $206.6 million for the third quarter 2026, compared to $198.8 million for the second quarter 2026, and $187.8 million for the third quarter 2025. The increase in non-interest income of $7.8 million from the second quarter 2026 was primarily due to increases in gain on sales of investment securities of $13.8 million, partially offset by a decrease in mortgage banking revenue of $5.2 million. The increase in non-interest income of $18.8 million from the third quarter 2025 was primarily driven by increases in service charges and fees and gain on sales of investment securities, partially offset by a decrease in mortgage banking revenue. Net revenue totaled $1.0 billion for the third quarter 2026, up $18.5 million, or 1.9%, from $995.7 million in the second quarter 2026, and $76.0 million, or 8.1%, from $938.2 million in the third quarter 2025. Non-interest expense was $595.1 million for the third quarter 2026, compared to $583.3 million for the second quarter 2026, and $544.4 million for the third quarter 2025. The increase in non-interest expense of $11.8 million from the second quarter 2026 was primarily due to an increase in salaries and employee benefits of $21.8 million, partially offset by a decrease of $13.8 million in deposit costs driven by decreased average ECR-related deposit balances. The increase in non-interest expense of $50.7 million from the third quarter 2025 was primarily attributable to increased salaries and employee benefits of $32.6 million and increased data processing costs of $7.7 million. These increases were partially offset by decreased deposit costs of $9.7 million driven by decreased average ECR-related deposit balances. The Company's efficiency ratio was 58.1% for the third quarter 2026, compared to 58.0% for the second quarter 2026, and 57.4% for the third quarter 2025. The Company’s efficiency ratio, adjusted for deposit costs 1 , was 50.0% for the third quarter 2026, compared to 48.9% for the second quarter 2026, and 47.8% for the third quarter 2025. Income tax expense was $61.9 million for the third quarter 2026, compared to $63.2 million for the second quarter 2026, and $53.3 million for the third quarter 2025. The decrease in income tax expense from the second quarter 2026 was primarily driven by increases in investment tax credits. The increase in income tax expense from the third quarter 2025 was primarily driven by an increase in pretax income. Net income was $277.2 million for the third quarter 2026, an increase of $8.4 million from $268.8 million for the second quarter 2026, and an increase of $16.7 million from $260.5 million for the third quarter 2025. Earnings per share totaled $2.45 for the third quarter 2026, compared to $2.36 for the second quarter 2026, and $2.28 for the third quarter 2025. The Company believes its pre-provision net revenue 1 ("PPNR"), which it defines as net revenue less non-interest expense, is a key metric for assessing the Company’s earnings power. For the third quarter 2026, the Company’s PPNR 1 was $419.1 million, up $6.7 million from $412.4 million in the second quarter 2026, and up $25.3 million from $393.8 million in the third quarter 2025. 1 See Reconciliation of Non-GAAP Financial Measures. Balance Sheet HFI loans, net of deferred fees, totaled $61.5 billion at September 30, 2026, compared to $60.9 billion at June 30, 2026, and $56.6 billion at September 30, 2025. The $600 million increase from the prior quarter end primarily reflected increases of $396 million in commercial real estate non-owner occupied loans and $336 million in commercial and industrial loans, partially offset by a $111 million decrease in residential real estate loans. The $4.9 billion increase from September 30, 2025 was primarily attributable to increases of $4.4 billion in commercial and industrial loans, $286 million in residential real estate loans, $210 million in commercial real estate non-owner occupied loans, and $173 million in construction and land development loans, partially offset by a $121 million decrease in commercial real estate owner occupied loans. HFS loans totaled $4.0 billion at September 30, 2026, compared to $4.3 billion at June 30, 2026, and $3.5 billion at September 30, 2025. The $396 million decrease from the prior quarter end primarily reflected lower loan funding volume during the quarter and unfavorable fair value changes resulting from higher interest rates. The $449 million increase from September 30, 2025 was primarily attributable to higher period-end inventory levels resulting from the timing of loan production and sales activity, as well as increased early buyout activity. The Company's allowance for credit losses on HFI loans comprises allowances for funded HFI loans and unfunded loan commitments. The allowance for loan losses as a percentage of funded HFI loans was 0.83% at September 30, 2026, 0.80% at June 30, 2026, and 0.78% at September 30, 2025. Including the allowance for unfunded loan commitments, the allowance for credit losses as a percentage of funded HFI loans was 0.93% at September 30, 2026, 0.89% at June 30, 2026, and 0.85% at September 30, 2025. Through credit linked note transactions, the Company effectively transfers a portion of the risk of losses on reference pools of loans to the purchasers of the notes. These transactions provide first-loss protection on reference pools of loans that totaled $7.6 billion, $7.8 billion, and $8.2 billion as of September 30, 2026, June 30, 2026, and September 30, 2025, respectively. However, as these note transactions are considered freestanding credit enhancements, the allowance for credit losses cannot be reduced for expected credit losses that these notes may mitigate. Accordingly, the allowance ratios include $11.6 million, $10.2 million, and $11.8 million related to these pools of loans as of September 30, 2026, June 30, 2026, and September 30, 2025, respectively. The allowance for credit losses to funded HFI loans ratio, adjusted to reduce the HFI loan balance by the amount of loans in covered reference pools, was 1.07% at September 30, 2026, 1.01% at June 30, 2026, and 1.00% at September 30, 2025. Deposits totaled $81.8 billion at September 30, 2026, a decrease of $119 million from June 30, 2026, and an increase of $4.5 billion from $77.2 billion at September 30, 2025. The decline in deposits from the prior quarter primarily reflected a $2.1 billion decrease in non-interest bearing deposits, partially offset by increases of $871 million in interest bearing demand deposits, $754 million in certificates of deposit, and $324 million in savings and money market accounts. Deposit optimization efforts drove the decline in non-interest bearing deposits, partially offset by strong commercial banking growth in interest bearing deposits. From September 30, 2025, interest bearing demand deposits, certificates of deposit, and savings and money market accounts increased $3.7 billion, $1.1 billion, and $583 million, respectively, while non-interest bearing deposits decreased $876 million. Non-interest bearing deposits totaled $25.8 billion at September 30, 2026, compared to $27.8 billion at June 30, 2026, and $26.6 billion at September 30, 2025. The Company’s ratio of HFI loans to deposits was 75.3% at September 30, 2026, compared to 74.4% at June 30, 2026, and 73.3% at September 30, 2025. Borrowings totaled $5.6 billion at September 30, 2026, compared with $6.2 billion at June 30, 2026, and $3.9 billion at September 30, 2025. Borrowings decreased $623 million from June 30, 2026, reflecting declines of $515 million in short-term borrowings and $108 million in long-term borrowings. Borrowings increased $1.8 billion from September 30, 2025, as a $3.3 billion increase in short-term borrowings was partially offset by a $1.5 billion decrease in long-term borrowings. Qualifying debt totaled $1.1 billion at both September 30, 2026 and June 30, 2026, compared with $681 million at September 30, 2025. The increase from September 30, 2025 primarily reflects the issuance of $400 million of subordinated debt during the quarter ended December 31, 2025. Total equity was $7.9 billion at September 30, 2026, compared to $8.1 billion at June 30, 2026, and $7.7 billion at September 30, 2025. The decrease from the prior quarter was primarily due to changes in AOCI related to higher interest rates, unrealized fair value losses of $338.0 million on the Company's available-for-sale securities, which are recorded in other comprehensive loss, net of tax, the repurchase of 1.15 million shares for $92.1 million, and dividends, partially offset by net income of $277.2 million. Third quarter cash dividends paid included $45.7 million, or $0.42 per share, for common stockholders; $3.2 million, or $0.27 per depositary share, for preferred stockholders; and $7.1 million on preferred stock of the Company's REIT subsidiary. The increase in equity from September 30, 2025 was primarily driven by net income, partially offset by dividends to stockholders and share repurchases. Since inception of the share repurchase program through September 30, 2026, the Company has repurchased 2.7 million shares for $212.5 million under its $300 million authorization. The Company's common equity tier 1 capital ratio was 10.9% at September 30, 2026, compared with 11.0% at June 30, 2026, and 11.3% at September 30, 2025. At September 30, 2026, tangible common equity, net of tax 1 , was 6.9% of tangible assets 1 , while total capital was 14.0% of risk-weighted assets. The Company’s tangible book value per share 1 was $62.22 at September 30, 2026, down 1.6% from $63.24 at June 30, 2026, and up 6.3% from $58.56 at September 30, 2025. The increase in tangible book value per share from September 30, 2025 was primarily attributable to net income. Total assets were $98.1 billion at September 30, 2026, down $629 million, or 0.6%, from $98.7 billion at June 30, 2026, and up 7.8% from $91.0 billion at September 30, 2025. The decrease in total assets from the prior quarter end reflected lower cash, HFS loans, and investment securities, partially offset by higher HFI loans. The increase in total assets from September 30, 2025 was primarily driven by growth in HFI and HFS loans and investment securities. 1 See Reconciliation of Non-GAAP Financial Measures. Asset Quality Provision for credit losses totaled $80.0 million for the third quarter 2026, compared to $80.4 million for the second quarter 2026, and $80.0 million for the third quarter 2025. Net loan charge-offs in the third quarter 2026 totaled $45.8 million, or 0.30% of average loans on an annualized basis, compared to $55.0 million, or 0.37% in the second quarter 2026, and $31.1 million, or 0.22%, in the third quarter 2025. The allowance for credit losses to funded HFI loans was 0.93% at September 30, 2026 compared to 0.89% and 0.85% at June 30, 2026 and September 30, 2025, respectively. Nonaccrual loans decreased $77 million during the quarter and $37 million from September 30, 2025, to $485 million. The decline in nonaccrual loans, combined with the increase in the allowance for credit losses, increased coverage of nonaccrual loans to 118%, from 96% at June 30, 2026, and 92% at September 30, 2025. Loans past due 90 days and still accruing interest totaled $58 million at September 30, 2026, compared with $55 million at June 30, 2026, and $49 million at September 30, 2025 (excluding government guaranteed loans of $214 million, $248 million, and $282 million, respectively). Loans past due 30-89 days and still accruing interest totaled $138 million at September 30, 2026, compared with $122 million at June 30, 2026, and $196 million at September 30, 2025 (excluding government guaranteed loans of $101 million, $102 million, and $149 million, respectively) a year-over-year decrease of $58 million. Criticized loans totaled $1.3 billion, an increase of $5 million during the quarter and $33 million from September 30, 2025.
