EAST WEST BANCORP REPORTS RECORD NET INCOME FOR FULL YEAR 2011 OF $245 MILLION; INCREASE IN ANNUAL DIVIDEND RATE TO $0.40 AND NEW $200 MILLION COMMON STOCK REPURCHASE PROGRAM

Pasadena, CA — January 19, 2012 — East West Bancorp, Inc. (Nasdaq: EWBC), parent company of East West Bank, the financial bridge between the United States and Greater China, today reported financial results for the fourth quarter and full year 2011. For the fourth quarter of 2011, net income was $66.2 million or $0.43 per dilutive share. For the full year 2011, net income was $245.2 million and net income available to common stockholders was $1.60 per dilutive share.

“East West earned $245.2 million for the full year 2011, the highest ever in our history,” stated Dominic Ng, Chairman and Chief Executive Officer of East West. “In the fourth quarter of 2011, East West earned net income of $66.2 million or $0.43 per share, up from $62.4 million or $0.41 per share in the third quarter. In fact, throughout 2011, East West consecutively increased both net income and EPS each quarter.”

Ng continued, “These strong results for the fourth quarter and full year 2011 were a direct result of our success in growing the loan portfolio and core deposits to record levels, while maintaining tight control on operating expenses and significantly reducing credit costs. Although the current environment continues to pose challenges for the financial services industry, East West has been able to outperform many of its peers. During 2011, we grew our noncovered commercial loan portfolio to $3.1 billion and increased core deposits by 16% or $1.4 billion to $10.3 billion. This growth was achieved while we maintained strong expense control and improved the efficiency ratio to 43%.”

“East West ended 2011 with record assets of $22 billion and record earnings of $245.2 million. Our balance sheet is healthy and our capital levels are excellent. As such, I am pleased to announce that the board of directors has approved a 100% increase in the annual common stock dividend rate to $0.40 per share and has also authorized the repurchase of $200 million of our common stock. As we look to 2012, we are confident

in our ability to prudently grow the balance sheet, improve our earnings power and return strong value to our shareholders,” concluded Ng.

Management Guidance

The Company is providing initial guidance for the first quarter and full year of 2012. The planned buyback of up to $200.0 million of the Company’s common stock is not factored into this guidance for the first quarter or full year of 2012. Management currently estimates that fully diluted earnings per share for the full year of 2012 will range from $1.72 to $1.76 or an increase of approximately 7% to 10% from 2011. This EPS guidance is based on overall asset growth of 2%, provision for loan losses of approximately $60 million and an adjusted net interest margin of approximately 3.85%1.

Management currently estimates that fully diluted earnings per share for the first quarter of 2012 will range from $0.41 to $0.43 per dilutive share. This EPS guidance is based on the following assumptions:

·Stable balance sheet

3

·A stable interest rate environment and an adjusted net interest margin of approximately 3.90%

·Provision for loan losses of approximately $15 to $20 million

·Total noninterest expense of approximately $100 million for the quarter, net of amounts to be reimbursed by the FDIC

·Effective tax rate of approximately 36.5%

Balance Sheet Summary

As of December 31, 2011, total assets grew to $22.0 billion compared to $21.8 billion at September 30, 2011, and $20.7 billion at December 31, 2010. The increase in the balance sheet is primarily due to loan growth of 2% or $291.1 million for the fourth quarter and loan growth of 5% or $751.9 million for the full year 2011. This growth was funded with an increase in deposits of 1% or $144.3 million for the fourth quarter and 12% or $1.8 billion for the full year 2011.

Loans receivable increased to $14.5 billion at December 31, 2011, compared to $14.2 billion at September 30, 2011 and $13.7 billion at December 31, 2010.  This increase in loans receivable was due to growth in the noncovered loan portfolio. During the fourth quarter, noncovered loan balances increased 5% or $507.9 million to $10.6 billion at December 31, 2011. The increase in noncovered loans during the fourth quarter was driven by growth in commercial and trade finance loans, single family loans and consumer loans which increased 4% or $130.3 million, 18% or $278.7 million, and 16% or $80.2 million, respectively.

Covered Loans

Covered loans totaled $3.9 billion as of December 31, 2011, a decrease of 5% or $216.8 million from September 30, 2011. The decrease in the covered loan portfolio was primarily due to payoffs and paydown activity, as well as charge-offs.

The covered loan portfolio is comprised of loans acquired from the FDIC-assisted acquisitions of United Commercial Bank (UCB) and Washington First International Bank (WFIB) which are covered under loss share agreements with the FDIC. During the fourth quarter, we recorded a net decrease in the FDIC indemnification asset and receivable included in noninterest income (loss) of $(20.4) million, largely due to continued improved credit performance of the UCB portfolio as compared to our original estimate.

Deposits

At December 31, 2011, total deposits equaled $17.5 billion as compared to $17.3 billion at September 30, 2011 and $15.6 billion at December 31, 2010. Throughout the year and continuing in the fourth quarter of 2011, we focused on growing commercial and low-cost core deposits and reducing our reliance on time deposits. Core deposits increased to a record $10.3 billion at December 31, 2011, or an increase of 5% or $482.7 million from September 30, 2011. Quarter to date, all core deposit categories grew, with the largest increases in money market deposits which increased 5% or $243.4 million to $4.7 billion, and demand deposits which increased 3% or $115.2 million to a record $3.5 billion.

4

Time deposits totaled $7.1 billion at December 31, 2011, or a decrease of 5% or $338.4 million from September 30, 2011.

Fourth Quarter 2011 Operating Results

Net Interest Income

The core net interest margin, excluding the net impact to interest income of $25.0 million resulting from covered loan activity and amortization of the FDIC indemnification asset, remained strong at 4.13% for the fourth quarter of 2011, as compared to 3.98% for the third quarter of 2011 and 4.43% for the fourth quarter of 2010. 1 Net interest income, adjusted for the net income of covered loan dispositions, totaled $204.0 million for the fourth quarter, an increase of 3% or $5.5 million from the third quarter of 20111.

The increase in both the core net interest margin and adjusted net interest income was primarily due to a reduction in the cost of deposits and an increase in loans receivable. In addition, although quarterly average interest-earning assets declined between the third and fourth quarters of 2011, the composition of interest earnings assets changed and thus resulted in an improvement in our yield on total interest-earning assets. Average loan balances for the fourth quarter totaled $14.3 billion, an increase of 2% or $259.6 million from the average loan balances for the third quarter. The impact of the increase in average loan balances was partially offset by a decrease in the loan yield on noncovered loans. The yield on noncovered loans was 4.76% for the fourth quarter, compared to 4.87% in the prior quarter.

The cost of deposits decreased to 0.55% for the fourth quarter of 2011, down 10 basis points from 0.65% in the third quarter of 2011. This improvement in the cost of deposits was primarily achieved through actively managing down higher interest-bearing deposit accounts, particularly time deposits. The average cost on time deposits declined by 11 basis points in the fourth quarter to 1.01%, resulting in cost savings of $2.0 million as compared to the third quarter of 2011.

Although operating in a low interest rate environment has been challenging, East West is taking measures to maintain a strong net interest margin while continuing prudent interest rate risk management practices. Additionally, management is confident that East West will continue to organically grow the loan portfolio.  As such, while the net interest margin may decrease from current levels, management still expects to maintain a relatively stable net interest margin and expects the adjusted net interest margin to approximate 3.90% for the first quarter of 2012 and 3.85% for the full year 2012.

Noninterest Income (Loss) & Expense

The Company reported total noninterest income  for the fourth quarter of 2011 of $937 thousand, compared to total noninterest (loss) of ($13.5) million in the third quarter of 2011 and noninterest (loss) of ($17.3) million in the fourth quarter of 2010. Branch fees, loan fees and letter of credit and foreign exchange income totaled $15.8 million in the fourth quarter of 2011, as compared to $17.4 million in the third quarter of 2011 and $13.7 million in the fourth quarter of 2010. Also included in noninterest income for the

5

fourth quarter of 2011 were gains on sales of SBA loans of $1.4 million and gains on sales of investment securities of $2.9 million.

Noninterest expense totaled $106.7 million for the fourth quarter of 2011, an increase of $2.1 million from the third quarter of 2011 and a decrease of $7.1 million from the fourth quarter of 2010.

Noninterest expense, excluding amounts to be reimbursed by the FDIC, totaled $98.1 million for the fourth quarter of 2011. 1 A summary of the noninterest expenses for the fourth quarter 2011, compared to the third quarter 2011 and fourth quarter 2010, is detailed below:

	Quarter Ended
	December 31, 2011		September 30, 2011		December 31, 2010
Total noninterest expense:	$	106,672	$	104,552	$	113,743
Amounts to be reimbursed on covered assets (80% of actual expense amount)	8,551		3,539		12,958
Prepayment penalties for FHLB advances and other borrowings	—		3,826		—
Noninterest expense excluding reimbursable amounts and prepayment penalties for FHLB advances and other borrowings	$	98,121	$	97,187	$	100,785

Overall, noninterest expense for the fourth quarter, excluding amounts to be reimbursed by the FDIC, was in line with the third quarter of 2011. Compensation and employee benefits and occupancy and equipment expense increased 3% or $1.2 million and 1% or $149 thousand, respectively, for the fourth quarter of 2011. Deposit insurance premium expense increased in the fourth quarter 2011 as compared to the prior quarter due to a third quarter adjustment resulting from a lower actual assessment in that period. Credit cycle costs including other real estate owned expense, loan related expense, and legal expense totaled $21.9 million for the fourth quarter 2011, as compared to $15.7 million for the third quarter 2011. Of total credit cycle costs incurred in the fourth quarter, $10.7 million related to covered loans and real estate owned for which we expect that 80% or $8.6 million is reimbursable by the FDIC.  Additionally, in the fourth quarter, amortization of investments in affordable housing partnerships decreased $2.4 million to $2.9 million and consulting expense decreased $1.0 million to $1.1 million, as compared to the prior quarter.

Management anticipates that in the first quarter of 2012, noninterest expense will total approximately $100.0 million, net of amounts reimbursable from the FDIC.

The effective tax rate for the fourth quarter was 35.9% as compared to 36.1% in the prior quarter. The effective tax rate is reduced from the statutory tax rate primarily due to the utilization of tax credits related to affordable housing investments.

Full Year 2011 Operating Results

For the full year 2011, adjusted net interest income reached a record $779.4 million, an increase of 3% or $25.5 million from 20101. The adjusted net interest margin for 2011 totaled 4.02% compared to 4.25% for 20101.  Although the low interest rate environment reduced our loan yields in 2011 as compared to 2010, East West took actions throughout the year to reduce deposit and borrowing costs. Our total cost of funds declined by 21 basis points from 1.15% for the full year 2010 to 0.94% for the full year 2011.

Total fees and other operating income for the full year 2011 increased to $79.5 million, a 19% or $12.8 million increase from full year 2010. As compared to 2010, branch fees increased 3% or $1.1 million, letters of credit fees and foreign exchange income increased 54% or $8.2 million, and other operating income increased 35% or $3.7 million. A summary of these fees and other income is detailed below:

	Year Ended				% Change
($ in thousands)	December 31, 2011		December 31, 2010		(Yr/Yr)
Branch fees	$	33,776	$	32,634	3	%
Letters of credit fees and foreign exchange income	23,140		14,987		54	%
Ancillary loan fees	8,350		8,526		-2	%
Other operating income	14,270		10,568		35	%
Total fees & other operating income	$	79,536	$	66,715	19	%

Noninterest expense totaled $435.6 million for the full year 2011, a decrease of 9% or $42.3 million as compared to 2010. The decrease in noninterest expense was due to a reduction in credit cycle costs and active expense control.  As compared to full year 2010, other real estate owned expenses declined 34% or $21.1 million, compensation expense declined 6% or $10.0 million, deposit insurance premium decreased 19% or $4.7 million, and data processing expense decreased 19% or $2.0 million. These decreases in the full year 2011 as compared to the full year 2010 were partially offset by an increase in amortization of investments in affordable housing partnerships of 73% or $7.3 million due to increased investments.

Credit Quality

Credit quality continued to improve in the fourth quarter and full year 2011. In each quarter of 2010 and 2011, East West reduced charge-offs and maintained a nonperforming asset to total asset ratio of less than 1.00%. The provision for loan losses was $20.0 million for the fourth quarter of 2011, a decrease of 9% or $2.0 million from the prior quarter, and a decrease of 33% or $9.8 million as compared to the fourth quarter of 2010. Total net charge-offs decreased to $21.8 million for the fourth quarter of 2011, a decrease of 10% or $2.5 million from the previous quarter and a decrease of 43% or $16.5 million compared to the prior year quarter.

Additionally, total nonaccrual loans and total nonperforming assets excluding covered assets, continued to remain low, with total nonperforming assets excluding covered

7

assets, to total assets under 1.00% for the ninth consecutive quarter. Nonperforming assets, totaled $175.0 million or 0.80% of total assets at December 31, 2011.

East West continues to maintain a strong allowance for noncovered loan losses at $209.9 million or 2.04% of noncovered loans receivable at December 31, 2011. This compares to an allowance for noncovered loan losses of $211.7 million or 2.16% of noncovered loans at September 30, 2011 and $230.4 million or 2.64% of noncovered loans at December 31, 2010. Our allowance for loan losses and provision for loan losses have declined for several quarters as a result of credit quality improvement, partially offset by increases in the allowance for loan losses on commercial and trade finance loans and single family loans, commensurate with the increases in these portfolios.
