CEO COMMENTARY:
“Western Alliance continued to deliver exceptional balance sheet growth in the third quarter, surpassing the $50 billion asset milestone, while generating record revenues, PPNR1 and earnings,” said Kenneth A. Vecchione, President and Chief Executive Officer. “Our unique national commercial business strategy produced our highest ever quarterly organic loan growth of $4.8 billion (63% annualized), with deposits also up $3.4 billion (32% annualized), driving a 14.3% increase in PPNR1 during the quarter to $317.1 million. Further, our ability to thoughtfully deploy liquidity into earning assets produced record net income of $236.9 million and earnings per share of $2.28 (or $2.30, excluding merger and restructure costs). Asset quality remained stable with nonperforming assets to total assets of 0.17% and annualized net charge-offs to average loans outstanding at a modest 0.04% for the quarter.”
Acquisition of AmeriHome Mortgage Company:
On April 7, 2021, the Company completed its previously announced acquisition of Aris Mortgage Holding Company, LLC, the parent company of AmeriHome Mortgage Company, LLC ("AmeriHome"). The Company's results include the financial results of AmeriHome beginning on April 7, 2021. Pursuant to accounting guidance, acquired assets and liabilities are recorded at estimated fair value as of the acquisition date. The estimated fair value of certain net assets are preliminary and are subject to measurement period adjustments. Based on AmeriHome's closing balance sheet and a $275 million premium, cash consideration was approximately $1.22 billion.

Income Statement
Net interest income was $410.4 million in the third quarter 2021, an increase of $39.9 million from $370.5 million in the second quarter 2021, and an increase of $125.7 million, or 44.2%, compared to the third quarter 2020. Continued HFI loan growth and interest income from AmeriHome's HFS loans drove the increase in net interest income from both the second quarter 2021 and the third quarter 2020.
The Company recorded a provision for credit losses totaling $12.3 million in the third quarter 2021, an increase of $26.8 million from the $14.5 million provision release in the second quarter 2021, compared to a provision for credit losses of $14.6 million in the third quarter 2020. The provision for credit losses during the third quarter 2021 is primarily due to loan growth and coverage of net charge-offs.
The Company’s net interest margin in the third quarter 2021 was 3.43%, a decrease from 3.51% in the second quarter 2021, and a decrease from 3.71% in the third quarter 2020. The decrease in net interest margin from the prior period is largely a result of lower yields on HFI loans, which were partially offset by deployment of excess liquidity into HFI and HFS loans. The decrease in net interest margin from the third quarter 2020 was driven by the lower rate environment, which lowered loan and investment security yields, offset by lower deposit costs.
Non-interest income was $138.1 million for the third quarter 2021, compared to $136.0 million for the second quarter 2021, and $20.6 million for the third quarter 2020. The increase in non-interest income from the second quarter 2021 was driven by an increase in net loan servicing revenue of $23.0 million, partially offset by decreases in net gain on loan origination and sale activities, fair value adjustments on assets measured at fair value, and income from equity investments, totaling $11.0 million, $5.4 million, and $4.3 million, respectively. The increase in non-interest income from the third quarter 2020 is primarily the result of mortgage banking related income from AmeriHome.
Net revenue was $548.5 million for the third quarter 2021, an increase of $42.0 million, or 8.3%, compared to $506.5 million for the second quarter 2021, and an increase of $243.2 million, or 79.7%, compared to $305.3 million for the third quarter 2020. The increase in net revenue from the second quarter 2021 and third quarter 2020 was driven by an increase in loan interest income generated from HFI loan growth and the AmeriHome HFS loans, coupled with an increase in non-interest income from mortgage banking related income.
Non-interest expense of $233.8 million for the third quarter 2021, or $231.4 million adjusted1 to exclude AmeriHome acquisition and restructure related expenses, compared to $244.8 million for the second quarter 2021, or $229.1 million adjusted1, and $124.1 million for the third quarter 2020. The Company’s efficiency ratio1, adjusted to exclude acquisition and restructure related expenses, was 41.5% for the third quarter 2021, compared to 44.5% in the second quarter 2021, and 39.7% for the third quarter 2020. The increase in adjusted non-interest expense1 from the third quarter 2020 is attributable to growth from the AmeriHome acquisition, which increased compensation costs and also introduced additional non-interest expense items, such as net loan servicing and loan acquisition and origination expenses.
Income tax expense was $65.5 million for the third quarter 2021, compared to $52.4 million for the second quarter 2021, and $30.8 million for the third quarter 2020.
Net income was $236.9 million for the third quarter 2021, an increase of $13.1 million from $223.8 million for the second quarter 2021, and an increase of $101.1 million from $135.8 million for the third quarter 2020. Earnings per share was $2.28 for the third quarter 2021, or $2.30 per share after adjusting for acquisition and restructure expenses, compared to $2.17, or $2.29 per share after adjusting for acquisition and restructure expenses, for the second quarter 2021, and $1.36 for the third quarter 2020. As discussed above, the increase in net income and earnings per share for the third quarter 2021 compared to the same quarter last year was driven by continued HFI loan growth and new activity related to the AmeriHome acquisition.
The Company views its pre-provision net revenue1 ("PPNR") as a key metric for assessing the Company’s earnings power, which it defines as net revenue less non-interest expense, adjusted for acquisition and restructure expenses. For the third quarter 2021, the Company’s PPNR1 was $317.1 million, up $39.7 million from $277.4 million in the second quarter 2021, and up $135.9 million from $181.2 million in the third quarter 2020. The increase in PPNR from the second quarter 2021 and third quarter 2020 was driven by HFI loan growth and the AmeriHome acquisition completed on April 7, 2021.
The Company had 3,061 full-time equivalent employees and 54 offices at September 30, 2021, compared to 3,075 employees and 53 offices at June 30, 2021, and 1,885 employees and 49 offices at September 30, 2020. The increase in employees from the prior year primarily relates to the addition of AmeriHome employees.

Balance Sheet
Gross HFI loans totaled $34.8 billion at September 30, 2021, an increase of $4.8 billion from $30.0 billion at June 30, 2021, and $8.8 billion from $26.0 billion at September 30, 2020. The increase in HFI loans from the prior quarter was driven by residential real estate and commercial and industrial loans, which increased $2.3 billion and $2.2 billion, respectively. From September 30, 2020, loan growth was also driven by residential real estate and commercial and industrial loans, which increased $5.1 billion and $2.9 billion, respectively. Construction and land development loans and CRE non-owner occupied loans also increased $643 million and $436 million, respectively, partially offset by a decrease in CRE owner occupied loans of $217 million from September 30, 2020. The Company's allowance for credit losses on HFI loans consists of an allowance for funded HFI loans and an allowance for unfunded loan commitments. At September 30, 2021, the allowance for loan losses to funded HFI loans was 0.71%, compared to 0.78% at June 30, 2021, and 1.19% at September 30, 2020. The allowance for credit losses, which includes the allowance for unfunded loan commitments, to funded HFI loans was 0.80% at September 30, 2021, compared to 0.88% at June 30, 2021, and 1.37% at September 30, 2020.
Deposits totaled $45.3 billion at September 30, 2021, an increase of $3.4 billion from $41.9 billion at June 30, 2021, and an increase of $16.4 billion from $28.8 billion at September 30, 2020. By deposit type, the increase from the prior quarter is primarily attributable to an increase of $1.6 billion from savings and money market accounts, $953 million from non-interest bearing demand deposits, and $767 million from interest bearing demand deposits. From September 30, 2020, deposits increased across all deposit types, with the largest increases in non-interest bearing demand deposits of $8.0 billion, savings and money market accounts of $6.9 billion, and interest-bearing demand deposits of $1.4 billion. Non-interest bearing deposits were $21.1 billion at September 30, 2021, compared to $20.1 billion at June 30, 2021, and $13.0 billion at September 30, 2020.
The table below shows the Company's deposit types as a percentage of total deposits:
Sep 30, 2021Jun 30, 2021Sep 30, 2020
Non-interest bearing46.5 %48.0 %45.1 %
Savings and money market38.5 37.7 36.7 
Interest-bearing demand10.9 10.0 12.3 
Certificates of deposit4.0 4.3 5.9 
The Company’s ratio of HFI loans to deposits was 76.9% at September 30, 2021, compared to 71.6% at June 30, 2021, and 90.1% at September 30, 2020.
Borrowings were $987 million at September 30, 2021, $595 million at June 30, 2021, and $10 million at September 30, 2020. The increase in borrowings from June 30, 2021 is due to an increase in overnight borrowings of $400 million. The increase in borrowings from September 30, 2020 is due to the assumption of borrowings related to the acquisition of AmeriHome, the issuance of $242 million in credit linked notes during the second quarter 2021, and an increase in overnight borrowings.
Qualifying debt totaled $1.1 billion at September 30, 2021 and June 30, 2021, compared to $619 million at September 30, 2020. The increase in qualifying debt from September 30, 2020 is primarily related to the issuance of $600 million in subordinated debt in June 2021, partially offset by redemption of $75 million in subordinated debt in July 2021.
Stockholders’ equity was $4.5 billion at September 30, 2021, compared to $4.0 billion at June 30, 2021, and $3.2 billion at September 30, 2020. The increase in stockholders' equity from June 30, 2021 is attributable to net income and net proceeds of $294.5 million from the issuance of preferred stock in September 2021, partially offset by dividends to shareholders. A cash dividend of $0.35 per share was paid to shareholders on August 27, 2021, totaling $36.5 million. The increase in stockholders' equity from September 30, 2020 is primarily a function of net income, issuance of preferred stock, and sales of common stock in a direct stock offering and under the Company's ATM program, partially offset by dividends to shareholders.
At September 30, 2021, tangible common equity, net of tax, was 6.9% of tangible assets1 and total capital was 12.6% of risk-weighted assets. The Company’s tangible book value per share1 was $34.67 at September 30, 2021, up 19.4% from September 30, 2020.
Total assets increased 7.6% to $52.8 billion at September 30, 2021, from $49.1 billion at June 30, 2021, and increased 58.3% from $33.3 billion at September 30, 2020. The increase in total assets from the prior year was driven by continued organic loan and deposit growth and the acquisition of net assets in the AmeriHome acquisition.
Asset Quality
Provision for credit losses totaled $12.3 million for the third quarter 2021, compared to a recovery of credit provisions of $(14.5) million for the second quarter 2021, and a provision for credit losses of $14.6 million for the third quarter 2020. Net loan charge-offs in the third quarter 2021 were $3.0 million, or 0.04% of average loans (annualized), compared to $0.1 million, or approximately 0.00%, in the second quarter 2021, and $8.2 million, or 0.13%, in the third quarter 2020.
Nonaccrual loans decreased $18.2 million to $78.1 million during the quarter and decreased $68.3 million from September 30, 2020. Loans past due 90 days and still accruing interest were zero at September 30, 2021 and June 30, 2021, compared to $28.1 million at September 30, 2020. Loans past due 30-89 days and still accruing interest totaled $23.6 million at September 30, 2021, an increase from $9.8 million at June 30, 2021, and a decrease from $24.3 million at September 30, 2020.
Repossessed assets totaled $11.5 million at September 30, 2021, an increase of $7.6 million from $3.9 million at June 30, 2021, and $2.9 million from $8.6 million at September 30, 2020. Classified assets totaled $264.9 million at September 30, 2021, an increase of $26.4 million from $238.5 million at June 30, 2021, and a decrease of $60.8 million from $325.7 million at September 30, 2020.
The ratio of classified assets to Tier 1 capital plus the allowance for credit losses, a common regulatory measure of asset quality, was 6.3% at September 30, 2021, compared to 6.4% at June 30, 2021, and 9.9% at September 30, 2020.
