HANMI FINANCIAL CORPORATION REPORTS RECORD NET INCOME OF $19.2
MILLION FOR 2003; EARNINGS PER SHARE INCREASE TO $1.34

— Total Assets Grow to a Record $1.79 Billion —

LOS ANGELES, CA. — January 26, 2004 (Market Wire) — Hanmi Financial Corporation (NASDAQ:HAFC), the holding company for Hanmi Bank, today reported net income for the year ended December 31, 2003 of $19.2 million, an increase of 12.8 percent compared with 2002 net income of $17.0 million. Fully diluted earnings per share increased in 2003 to $1.34 compared with $1.20 in 2002.

Fourth quarter pre-tax income was $9.9 million, an increase of 37.0 percent compared with $7.2 million in the same period of 2002. Fourth quarter earnings were reduced by $929,000, or $0.06 per fully diluted share, as a result of the reversal of certain net state tax benefits recorded in the first three quarters of 2003. Fourth quarter income exclusive of such reversals was $6.0 million, or $0.42 per fully diluted share.

Fourth quarter 2003 net income was $5.1 million, an increase of 5.9 percent compared with $4.8 million in the same period of 2002. Fourth quarter 2003 fully diluted earnings per share were $0.35, compared with $0.34 in the fourth quarter of 2002.

“This was an extraordinary year both in terms of our financial performance and the building of the foundation for a successful future for Hanmi Bank,” said Jae Whan Yoo, President and CEO. “We are pleased with our strong financial results: our net interest income increased 18.0 percent and our total assets grew 22.6 percent in 2003 to a record $1.79 billion, and our net loans increased 28 percent during the year to $1.25 billion. From this position of strength, we are looking forward to the next steps under our definitive agreement to acquire Pacific Union Bank. The combination, which we hope to complete in the second quarter of 2004, will position Hanmi Bank as the premier Korean-American bank, second to none in the U.S. I am also pleased to report the progress of both banks in developing a post-merger integration plan.”

Net Interest Income Before Provision for Loan Losses

Net interest income before provision for loan losses was $16.5 million for the fourth quarter of 2003, an increase of $4.1 million, or 32.7 percent, compared with $12.4 million for the same quarter in 2002. Net interest income before provision for loan losses for the full year increased by $8.7 million, or 18 percent, to $57.0 million compared with $48.3 million for 2002. The increase in net interest income was primarily due to an increase of average interest-earning assets over average interest bearing liabilities. The net interest margin was 3.99 percent for the fourth quarter of 2003 and 3.73 percent for the full year.

Average interest-earning assets increased $333.8 million or 25.3 percent over the fourth quarter of 2002 and provided an additional $3.7 million of interest income compared with the fourth quarter of 2002. The majority of this growth was funded by a $252 million, or a 20.2 percent, increase in total deposits and a $48 million increase in the quarterly average balance of Federal

Home Loan Bank borrowings. However, interest expense decreased by $403,000 due to faster re-pricing of interest-bearing liabilities.

Provision for Loan Losses

The provision for loan losses represents the charge against current earnings that is determined by management, through a disciplined credit review process, as the amount needed to maintain an allowance that is sufficient to absorb loan losses inherent in the Company’s loan portfolio. The provision for loan losses was $1.3 million in the fourth quarter of 2003 compared with $1.7 million for the fourth quarter of 2002.

Non-interest Income

Non-interest income was $5.1 million for the fourth quarter of 2003, which represented a decrease of 10.2 percent compared with $5.7 million recognized during the same quarter in 2002. The decrease was mainly due to a decrease in the gain on sales of securities, offset by increases in service charges on deposit accounts and international trade finance fees. The gain on sales of available-for-sale securities decreased by $1.3 million to $244,000, compared with $1.5 million during the fourth quarter of 2002. Other non-interest income increased by 16.8 percent or $695,000, which includes a $291,000 increase in service charges on deposit accounts and a $158,000 increase in trade finance fees.

Non-interest Expense

Non-interest expense increased by $1.2 million or 12.7 percent to $10.4 million in the fourth quarter of 2003 compared with $9.2 million in the fourth quarter of 2002. The increase during the fourth quarter of 2003 was primarily attributable to increases in salaries and employee benefits, due to the opening of two new branches.

Income Taxes

The provision for taxes for the fourth quarter of 2003 was $4.8 million, bringing the provision for the full year to $12.4 million, at an effective rate of 39.3 percent. The provision for the fourth quarter includes the reversal of California tax benefits arising from certain transactions involving a real estate investment trust (REIT). The California Franchise Tax Board has taken the position that such tax benefits will be disallowed pursuant to California Senate Bill 614 and Assembly Bill 1601, which were enacted in October 2003. The Company continues to believe that it is entitled to the benefits of them under the law. However, realization of them in the near term is not assured, and for that reason the Company has reversed all REIT consent dividend benefits recorded in 2003.

Financial Position

Total assets were $1.79 billion at December 31, 2003, up 22.6 percent from the balance of $1.46 billion at December 31, 2002, primarily reflecting the growth in commercial real estate loans and commercial loans. Hanmi Bank’s investment securities portfolio increased 49.4 percent to $417.7 million at December 31, 2003, up $138.1 million compared to $279.5 million at December 31, 2002.

At December 31, 2003, net loans totaled $1.25 billion, an increase of $272.9 million or 28.0 percent from $974.1 million at December 31, 2002. The majority of the growth was in commercial and real estate loans, which resulted primarily from new business. Commercial loans grew by $138.1 million to $711.0 million at December 31, 2003, compared to $572.9 million at December 31, 2002. Real estate loans increased by $127.8 million to $499.4 million at December 31, 2003, compared to $371.6 million at December 31, 2002.

The growth in total assets was funded by increases in customer deposits of $161.9 million, up by 12.6 percent, to $1.45 billion. These rising balances were led by increases in time deposits of $84.3 million, up 14.5 percent to $667.8 million, non-interest bearing accounts of $63.0 million, up 15.3 percent to $475.1 million, money market checking accounts of $15.8 million, up 8.3 percent to $206.1 million, and offset by a decrease in savings accounts of $1.3 million or 1.3 percent to $96.9 million.

The Company’s borrowings mostly take the form of advances from the Federal Home Loan Bank of San Francisco (“FHLB”) and repurchase agreements. Advances from the FHLB were $148.4 million, and securities sold under agreements to repurchase were $9.5 million at December 31, 2003.

Asset Quality

Total non-performing assets (“NPAs”), which include accruing loans due 90 days or more, non-accrual loans, and other real estate owned (“OREO”) assets increased by $2.2 million to $8.7 million at year end 2003 from $6.5 million at December 31, 2002. Non-performing assets as a percentage of gross loans increased to 0.68 percent at December 31, 2003 from 0.65 percent at December 31, 2002.

At December 31, 2003, accruing loans 90 days or more past due were $557,000, down $60,000 from $617,000 at December 31, 2002. However, non-accrual loans were $8.1 million, up $2.2 million from $5.9 million at December 31, 2002. There were no OREO assets at December 31, 2003.

The allowance for loan losses was $14.7 million, and represented the amount needed to maintain an allowance that the Company believes should be sufficient to absorb loan losses inherent in its loan portfolio. The allowance for loan losses represented 1.16 percent of gross loans and 170.1 percent of non-performing loans at December 31, 2003. The comparable ratios were 1.24 percent of year-end 2002 gross loans and 189.5 percent of non-performing loans at December 31, 2002.
