EAST WEST BANCORP REPORTS RECORD NET INCOME FOR FULL YEAR 2017

OF $505.6 MILLION AND DILUTED EARNINGS PER SHARE OF $3.47,

BOTH UP BY 17% FROM THE PRIOR YEAR

Pasadena, California - January 25, 2018 - East West Bancorp, Inc. (“East West” or the “Company”) (Nasdaq: EWBC), parent company of East West Bank, the financial bridge between the United States and Greater China, today reported its financial results for the fourth quarter and full year of 2017. For the fourth quarter of 2017, net income was $84.9million or $0.58 per diluted share. For the full year 2017, net income was $505.6 million or $3.47 per diluted share.

“Our full year 2017 record earnings increased by 17% year-over-year, reflecting strong revenue growth augmented by contained expenses and credit costs. In 2017, total loans grew $3.5 billion or 14% year-over-year, to a record $29.1 billion from $25.5 billion as of December 31, 2016,” stated Dominic Ng, Chairman and Chief Executive Officer of East West. “Total deposits grew $2.3 billion or 8% year-over-year, to a record $32.2 billion as of December 31, 2017 from $29.9 billion at the end of the previous year.”

“During the year, East West’s net interest margin expanded by 18 basis points, reflecting our loan growth, attractive deposit mix, and the benefits of higher interest rates on our asset sensitive balance sheet,” continued Ng. “This has been a key component of our profitability; in 2017, we earned a return on average assets of 1.41% and a return on average equity of 13.7%. I would like to thank our 3,000 associates for their dedication and diligence in delivering another year of strong earnings for our shareholders.”

“At East West, we focus on creating sustainable, expandable and profitable customer relationships. Our consistent financial results year after year reflect the value of this customer focus and our business model as the financial bridge between the East and the West. We are committed to investing in technology and human capital to drive our business forward, continuously strengthening our infrastructure to ensure prudent risk management and operational excellence,” concluded Ng.

MANAGEMENT OUTLOOK FOR 2018

Our current outlook for the expected full year 2018 results, compared to our full year 2017 results, is as follows:

• End of Period Loans: increase at a percentage rate of approximately 10%.

• Net Interest Margin (excluding the impact of ASC 310-30 discount accretion): between 3.65% and 3.75%.

• Noninterest Expense (excluding tax credit amortization & deposit premium amortization): increase at a percentage rate in the high single digits.

• Provision for Credit Losses: in the range of $70 million to $80 million.

• Tax Items: projecting investment in tax-advantaged credits of $105 million, excluding low income housing tax credits, and associated tax credit amortization expense of $85 million. Projecting full year effective tax rate of approximately 16%.

• Interest Rates: our outlook incorporates the current forward rate curve; as such, it currently assumes three fed funds rate increases in the year 2018: in March, June and September.

OPERATING RESULTS SUMMARY

Fourth Quarter 2017 Compared to Third Quarter 2017

Net Interest Income

Net interest income totaled $319.7 million, a 5% increase from $303.2 million.

• Adjusted net interest income, excluding ASC 310-30 discount accretion income, grew to $312.7 million, a 5% increase from $298.6 million.

• Average loans of $28.6 billion grew by $1.1 billion or 16% annualized from $27.5 billion.

• Average deposits of $32.3 billion grew by $1.2 billion or 15% annualized from $31.1 billion.

• Average noninterest-bearing demand deposits of $11.5 billion grew by $875.3 million or 33% annualized from $10.7 billion.

Net Interest Margin

• Excluding the impact of ASC 310-30 discount accretion income, adjusted NIM expanded by three basis points to 3.49% from 3.46%.

Noninterest Expense

Noninterest expense of $175.4 million includes $151.9 million of adjusted⁵ noninterest expense, $21.9 million amortization of tax credit and other investments, and $1.6 million amortization of core deposit intangibles.

• Adjusted noninterest expense of $151.9 million increased by $13.0 million, or 9% linked quarter. This growth was driven by a $10.8 million increase in compensation and employee benefits, largely reflecting increased hiring along with increases in bonus accrual and restricted stock compensation.

• The adjusted⁵ efficiency ratio was 41.6% in the fourth quarter, compared to 39.8% in the third quarter, due to the growth in expenses.

TAX RELATED ITEMS

The Company’s full year 2017 effective tax rate was 31%, resulting in tax expense of $229.5 million, compared to an effective tax rate of 25% and tax expense of $140.5 million for the full year 2016. The effective tax rates for the full year and the fourth quarter of 2017 were elevated because of nonrecurring items related to the enactment of the Tax Cuts and Jobs Act, which lowered the federal corporate tax rate to 21% from 35%.

• These nonrecurring items included a $33.1 million remeasurement of the net deferred tax asset and a $7.9 million remeasurement of investments in qualified affordable housing partnerships, recorded in the fourth quarter of 2017. These adjustments are management’s best estimate based on the information available as of this earnings release and are subject to change as final tax calculations are completed in conjunction with the filing of the Form 10-K.

• Tax expense in the fourth quarter of 2017 was $89.2 million, compared to $42.6 million in the third quarter of 2017. The total impact of the Tax Cuts and Jobs Act was an increase in tax expense of $41.7 million, or $0.29 per share, in the fourth quarter of 2017. Excluding this impact, the adjusted⁶ tax expense for the fourth quarter of 2017 was $47.5 million and the adjusted⁶ effective tax rate was 27%. Adjusted⁶ tax expense for the full year 2017 was $187.8 million and the adjusted⁶ effective tax rate was 26%.

• For the full year 2018, the Company is projecting an effective tax rate of approximately 16%.

CREDIT QUALITY

The allowance for loan losses totaled $287.1 million, or 0.99% of loans HFI, as of December 31, 2017, compared to $285.9 million, or 1.00% of loans HFI, as of September 30, 2017, and $260.5 million, or 1.02% of loans HFI, as of December 31, 2016.

• The provision for credit losses recorded for the current quarter was $15.5 million, compared to $13.0 million for the third quarter of 2017, and $10.5 million for the fourth quarter of 2016.

• For the fourth quarter of 2017, net charge-offs were $15.7 million or 0.22% of average loans HFI, annualized. This compares to net charge-offs of $3.8 million or 0.06% of average loans HFI, annualized, for the third quarter of 2017, and net charge-offs of $8.0 million or 0.13% of average loans HFI, annualized, for the fourth quarter of 2016.

In the third quarter of 2017, the Company sold its insurance brokerage business, East West Insurance Services, Inc. (“EWIS”). On December 22, 2017, the Tax Cuts and Jobs Act was enacted, which resulted in an additional income tax expense of $41.7 million recognized in the fourth quarter of 2017. Management believes that presenting the computations of the adjusted diluted earnings per common share, return on average assets and return on average equity that exclude the impact of the Tax Cuts and Jobs Act and after-tax gains on sales of the commercial property and EWIS business (where applicable) provides clarity to financial statement users regarding the ongoing performance of the Company and allows comparability to prior periods.

Table 14
Adjusted efficiency ratio represents adjusted noninterest expense divided by adjusted revenue. Adjusted pre-tax, pre-provision profitability ratio represents the aggregate of adjusted revenue less adjusted noninterest expense, divided by average total assets. Adjusted revenue represents the aggregate of net interest income and adjusted noninterest income, where adjusted noninterest income excludes the gains on sales of the commercial property and EWIS business (where applicable). Adjusted noninterest expense excludes the amortization of tax credit and other investments, the amortization of core deposit intangibles and the reversal of a legal accrual (where applicable). The Company believes that the ratios presented below provide clarity to financial statement users regarding the ongoing performance of the Company and allow comparability to prior periods.

The Company uses certain non-GAAP financial measures to provide supplemental information regarding the Company’s performance. Tangible equity and tangible equity to tangible assets ratio are non-GAAP financial measures. Tangible equity and tangible assets represent stockholders’ equity and total assets, respectively, which have been reduced by goodwill and other intangible assets. Given that the use of such measures and ratios are more prevalent in the banking industry, and such measures are used by banking regulators and analysts, the Company has included them for discussion.
