EAST WEST BANCORP REPORTS NET INCOME FOR FIRST QUARTER OF 2023

OF $322 MILLION AND DILUTED EARNINGS PER SHARE OF $2.27, UP 37% YEAR-OVER-YEAR

Pasadena, California – April 20, 2023 – East West Bancorp, Inc. (“East West” or the “Company”) (Nasdaq: EWBC), parent company of East West Bank, reported its financial results for the first quarter of 2023. First quarter 2023 net income was $322.4 million, or $2.27 per diluted share, up from $237.7 million, or $1.66 per diluted share in the prior year period. Year-over-year, earnings per share increased 37%. Total loans reached a record $48.9 billion as of March 31, 2023.

“East West’s ability to consistently generate industry-leading profitability while maintaining above peer capital ratios are strengths in any business cycle. East West continued to deliver in the first quarter, despite the banking industry and market disruption that occurred in mid-March,” stated Dominic Ng, Chairman and Chief Executive Officer of East West. “For the first quarter of 2023, we earned industry-leading returns of 2.0% on average assets and 22.9% on average tangible common equity1. Net interest margin was a healthy 3.96%, asset quality continued to be excellent with net charge-offs of 0.01% annualized. With our strong earnings, all capital ratios expanded, and our total capital ratio increased to 14.5%.”

“Our balance sheet positions us to excel. Our loan portfolio is granular and well-diversified without significant concentration in any industry or sector. We have a strong, granular deposit franchise with over 550,000 deposit accounts spanning consumer, small business, non-profit and corporate customers. Our capital and liquidity are strong. We are steadfast in our positive outlook for East West’s performance,” concluded Ng.

BALANCE SHEET

•Total Assets – Total assets reached a record $67.2 billion as of March 31, 2023, an increase of $3.1 billion, or 5%, from $64.1 billion as of December 31, 2022.

First quarter 2023 average interest-earning assets of $61.5 billion were up $1.1 billion, or 2%, from $60.4 billion in the fourth quarter of 2022. Quarter-over-quarter, average loans grew $542.7 million and average interest-bearing cash and deposits with banks increased $465.9 million.

•Strong Capital Levels – As of March 31, 2023, stockholders’ equity was $6.3 billion, or $44.62 per share, up 5% quarter-over-quarter. The stockholders’ equity to assets ratio was 9.38% as of March 31, 2023, an increase of five basis points quarter-over-quarter.

As of March 31, 2023, tangible book value3 per share was $41.28, up 6% quarter-over-quarter. The tangible common equity ratio3 was 8.74%, an increase of eight basis points quarter-over-quarter.

All of East West’s regulatory capital ratios are well in excess of regulatory requirements for well-capitalized institutions, as well as above regional and national bank averages. The common equity tier 1 (“CET1”) capital ratio increased to 13.06%, and the total risk-based capital ratio increased to 14.50%, as of March 31, 2023.

•Total Loans – Total loans reached a record $48.9 billion as of March 31, 2023, an increase of $696.8 million, or 1%, from $48.2 billion as of December 31, 2022. Year-over-year, total loans grew $5.4 billion, or 12%, from $43.5 billion as of March 31, 2022.

First quarter 2023 average loans of $48.1 billion grew $542.7 million, or 1%, from the fourth quarter of 2022. Average growth in residential mortgage and commercial real estate loans was partially offset by a modest decrease in average commercial & industrial loans.

•Total Deposits – Total deposits were $54.7 billion as of March 31, 2023, a decrease of $1.2 billion, or 2%, from $56.0 billion as of December 31, 2022. Year-over-year, deposits declined $201.0 million, or 0.4%, from $54.9 billion as of March 31, 2022. Noninterest-bearing deposits made up 33% of our total deposits as of March 31, 2023.

First quarter 2023 average deposits of $55.0 billion were essentially unchanged from the fourth quarter of 2022. During the first quarter, time deposits grew due to a successful branch-based CD campaign for the Lunar New Year. This was offset by declines in other deposit categories, which reflected customers seeking higher yields in a rising interest rate environment and the banking industry disruption in mid-March.

As of March 31, 2023, East West Bank’s domestic deposits were $52.5 billion, of which insured or otherwise collateralized deposits were estimated at $29.6 billion. East West Bank’s domestic uninsured deposit ratio improved to 44% as of March 31, 2023, compared to 50% as of December 31, 2022. Since the industry disruption in mid-March, the Company has worked with customers to expand their FDIC insurance coverage, primarily through the utilization of fully insured sweep programs. East West’s borrowing capacity, cash and cash equivalents well exceed our uninsured deposit balances.

•Conservative Liquidity Management –Cash and cash equivalents increased 70% to $5.9 billion as of March 31, 2023, up from $3.5 billion as of December 31, 2022. This increase in on-balance sheet liquidity was in response to the recent volatility in the banking industry and reflects East West’s conservative liquidity management practices. The increase in cash and cash equivalents was primarily funded with borrowings from the Bank Term Funding Program (“BTFP”) totaling $4.5 billion at a rate of 4.37% as of March 31, 2023.

As of March 31, 2023, East West Bank’s borrowing capacity, plus cash and cash equivalents was $30.6 billion, equivalent to 134% of total uninsured and uncollateralized deposits of $22.8 billion. As of December 31, 2022, borrowing capacity, plus cash and cash equivalents was $26.4 billion, equivalent to 99% of total uninsured and uncollateralized deposits.

3 Tangible book value and the tangible common equity ratio are non-GAAP financial measures. See reconciliation of GAAP to non-GAAP measures in Table 11.

OPERATING RESULTS

First Quarter Earnings – First quarter 2023 net income was $322.4 million, a decrease of 4% from $336.8 million for the fourth quarter of 2022, and an increase of 36% from $237.7 million for the first quarter of 2022. First quarter 2023 diluted earnings per share (“EPS”) were $2.27, a decrease of 4% from $2.37 per diluted share for the fourth quarter of 2022, and an increase of 37% from $1.66 per diluted share for the year-ago quarter.

First quarter 2023 adjusted net income4 was $329.5 million, and adjusted diluted EPS4 was $2.32, a decrease of 2% quarter-over-quarter for both metrics. Noninterest income in the first quarter of 2023 included a $10.0 million (before tax) impairment loss on a subordinated debt security of a failed bank, which was $7.1 million after tax, or $0.05 per share.

First Quarter 2023 Compared to Fourth Quarter 2022

Net Interest Income and Net Interest Margin

Net interest income (“NII”) totaled $599.9 million, a decrease of 1% from $605.5 million. Net interest margin (“NIM”) of 3.96% declined two basis points from 3.98%.

•The change in NII reflects day count in the first quarter (90 days) compared with the fourth quarter (92 days). Equalizing for day count, the 2% of quarter-over-quarter average earning asset growth more than offsets the two basis points of NIM contraction.

•The change in NIM was primarily driven by a higher cost of interest-bearing deposits and changes in the deposit mix in favor of higher-cost deposits, partially offset by expanding earning asset yields.

•The average loan yield was 6.14%, up 55 basis points from the fourth quarter. The average interest-earning asset yield was 5.51%, up 51 basis points from the fourth quarter.

•The average cost of funds was 1.69%, up 58 basis points from the fourth quarter. The average cost of deposits was 1.60%, up 54 basis points.

•The changes in yields and rates reflected rising benchmark interest rates.

Noninterest Income

Noninterest income totaled $60.0 million in the first quarter, a decrease of $4.9 million, or 8%, from $64.9 million in the fourth quarter.

•Fee income and net gains on sales of loans were $66.3 million, up slightly from $66.0 million in the fourth quarter, reflecting higher lending and wealth management fees. The quarterly change in foreign exchange (“FX”) income reflected higher customer-driven FX fee income that was more than offset by an unfavorable change in mark-to-market adjustments on FX positions.

•Interest rate contracts and other derivative income was $2.6 million in the first quarter, compared with a loss of $0.6 million in the fourth quarter. The change reflected both growth in customer-driven revenue and a favorable change in mark-to-market adjustments.

Noninterest Expense

Noninterest expense totaled $218.4 million in the first quarter, compared with $257.1 million in the fourth quarter. First quarter noninterest expense consisted of $204.0 million of adjusted noninterest expense5, $10.1 million in amortization of tax credit and other investments, $0.4 million in amortization of core deposit intangibles, and $3.9 million in repurchase agreements’ extinguishment cost.

•Adjusted noninterest expense of $204.0 million increased $11.9 million, or 6%, from $192.1 million in the fourth quarter. The linked quarter change primarily reflected seasonal first quarter increase in compensation and employee benefits expense, and higher deposit insurance premiums and regulatory assessments.

•In the first quarter of 2023, the Company prepaid $300 million of repurchase agreement funding, which had carried a rate of 6.74%.

•Amortization of tax credit and other investments totaled $10.0 million in the first quarter, compared with $64.6 million in the fourth quarter. Quarter-over-quarter variability in the amortization of tax credits and other investments primarily reflects the impact of investments that close in a given period.

•The efficiency ratio was 33.1% in the first quarter, compared with 38.3% in the fourth quarter and the adjusted efficiency ratio4 was 30.5% in the first quarter, compared with 28.7% in the fourth quarter.

4 Adjusted net income and adjusted EPS are non-GAAP financial measures. See reconciliation of GAAP to non-GAAP measures in Table 12.

5 Adjusted noninterest expense and the adjusted efficiency ratio are non-GAAP financial measures. See reconciliation of GAAP to non-GAAP measures in Table 10.

TAX RELATED ITEMS

First quarter 2023 income tax expense was $99.0 million, and the effective tax rate was 23.5%. The effective tax rate for the full year 2022 was 20.1%.

ASSET QUALITY

The asset quality of our loan portfolio continues to be excellent. First quarter 2023 provision for credit losses was $20.0 million, compared with $25.0 million in fourth quarter 2022.

•The allowance for loan losses increased to $619.9 million, or 1.27% of loans held-for-investment (“HFI”), as of March 31, 2023, compared with $595.6 million, or 1.24% of loans HFI, as of December 31, 2022.

•First quarter 2023 net charge-offs were $0.6 million or annualized 0.01% of average loans HFI, down from net charge-offs of $10.1 million, or annualized 0.08% of average loans HFI, for the fourth quarter of 2022.

•The nonperforming assets ratio improved to 0.14% of total assets as of March 31, 2023, down from 0.16% as of December 31, 2022. Nonperforming assets decreased $6.4 million, or 6%, quarter-over-quarter to $93.4 million as of March 31, 2023, down from $99.8 million as of December 31, 2022.

•The criticized loans ratio increased one basis point quarter-over-quarter to 1.87% of loans HFI as of March 31, 2023, compared with 1.86% as of December 31, 2022. Criticized loans increased $18.1 million, or 2%, quarter-over-quarter to $914.1 million as of March 31, 2023, compared with $896.0 million as of December 31, 2022.

Leverage ratio	10.02%	9.80%	9.26%
Tangible common equity ratio (c)	8.74%	8.66%	8.47%

(a)The Company has elected to use the 2020 Current Expected Credit Losses (CECL) transition provision in the calculation of its March 31, 2023, December 31, 2022 and March 31, 2022 regulatory capital ratios. The Company’s March 31, 2023 regulatory capital ratios and RWA are preliminary.

(b)Under regulatory guidelines, on-balance sheet assets and credit equivalent amounts of derivatives and off-balance sheet items are assigned to one of several broad risk categories based on the nature of the obligor, or, if relevant, the guarantor or the nature of any collateral. The aggregate dollar value in each risk category is then multiplied by the risk weight associated with that category. The resulting weighted values from each of the risk categories are aggregated for determining total RWA.

(c)Tangible common equity ratio is a non-GAAP financial measure. See reconciliation of GAAP to non-GAAP measures in Table 11.

The Company uses certain non-GAAP financial measures to provide supplemental information regarding the Company’s performance. Adjusted efficiency ratio represents adjusted noninterest expense divided by adjusted revenue. Adjusted pre-tax, pre-provision profitability ratio represents total adjusted revenue less adjusted noninterest expense, divided by average total assets. Adjusted revenue excludes the write-off of an AFS debt security. Adjusted noninterest expense excludes the amortization of tax credit and other investments, the amortization of core deposit intangibles and the repurchase agreements’ extinguishment cost. Management believes that the measures and ratios presented below provide clarity to financial statement users regarding the ongoing performance of the Company and allow comparability to prior periods.
