Board of Directors Increases Cash Dividend

SEATTLE — Washington Mutual, Inc. (NYSE: WM) today announced earnings of $1.03 billion, or $1.12 per diluted share, for the quarter ended Sept. 30, 2003, up 10 percent on a per share basis from $981 million, or $1.02 per diluted share for the same period a year ago.

Based on the quarter’s earnings and the company’s capital generating ability, Washington Mutual’s Board of Directors declared a cash dividend of 41 cents per share on the company’s common stock, up one cent from 40 cents per share in the previous quarter. The company has now increased its cash dividend for 33 consecutive quarters.

Additional highlights of the recently completed quarter included:

• Continued growth in net retail checking accounts, one of the company’s key relationship-building products, which increased by 245,000 during the quarter; and total net retail checking accounts were up 11 percent since Sept. 30, 2002.

• A decline in nonperforming assets as a percentage of total assets to 0.78 percent from 0.82 percent at the end of the second quarter.

“Continued growth of accounts and our key loan portfolios, and the expansion of our national franchise led to another solid quarter for the company” said Kerry Killinger, Washington Mutual’s chairman, president and CEO. “Although the period was marked by significant volatility in interest rates, we continued to see positive trends in the key drivers of our business.”

“In addition, we took another evolutionary step toward our mission to become the nation’s leading retailer of financial services by realigning our organization around our two primary customer groups — consumers and commercial clients. This move will result in a much more integrated and unified retailing strategy focused on maximizing household growth and multiple product relationships with our customers nationally. In addition, it positions us more effectively to deliver a superior customer experience across all channels and drive efficiencies and operational excellence across the enterprise.”

THIRD QUARTER RESULTS

Net Interest Income

For the third quarter of 2003, net interest income declined slightly to $1.95 billion compared with $2.03 billion in the second quarter of 2003. Growth in average loans held in portfolio partially mitigated a decline in the net interest margin. The net interest margin in the current quarter declined, as expected, to 3.15 percent, a decrease of 15 basis points from the second quarter of 2003 and a decrease of 21 basis points from the third quarter of 2002 mainly due to the continued downward repricing of loans and securities from the higher interest rate environment during the past twelve months.

Noninterest Income

Noninterest income remained steady at $1.65 billion compared with $1.63 billion in the second quarter of 2003, and up 20 percent from the third quarter of 2002.

Consumers continued to choose Washington Mutual to serve their financial needs, leading to an increase of 245,000 net retail checking accounts during the third quarter and an increase of over 791,000 net retail checking accounts over the past twelve months.

Depositor and other retail banking fees increased $45 million to $471 million, up 11 percent from $426 million in the third quarter of 2002.

During the third quarter, the company recorded a net loss from mortgage loans of $126 million, after revaluation gains on derivatives (loans held for sale risk management), compared with a net gain of $475 million in the prior quarter. The loss was due, in part, to significant volatility in interest rates during the quarter as well as previously reported operational issues in the company’s mortgage business. “We have identified the issues that led to these challenges and have implemented measures to address them,” Killinger said.

The impact of the third quarter loss from mortgage loans was mitigated by a net recovery from the mortgage servicing rights valuation reserve and lower mortgage servicing rights amortization, as well as gains from the sale of available-for-sale securities.

Lending

Strong loan applications in the previous quarter contributed to the record loan volume of $130.59 billion in the third quarter, up 73 percent from $75.48 billion in the third quarter of 2002 and 9 percent from $120.32 billion in the second quarter of 2003. Despite the third quarter’s record loan volume, home loan applications for the month of September were approximately 50 percent less than in July when they reached a peak for the year.

Efficiency Ratio

For the quarter, the efficiency ratio was 51.69 percent compared with 52.49 percent in the second quarter of 2003 and 48.99 percent in the third quarter of 2002. Noninterest expense totaled $1.86 billion, which was down slightly from $1.92 billion during the second quarter of 2003.

Credit Risk Management

The loan portfolio continued to perform within expectations and consistently with recent quarters. Net charge-offs were $111 million, down slightly from $118 million in the second quarter of 2003. Nonperforming assets declined $89 million from June 30, 2003 to $2.22 billion and represented 0.78 percent of total assets. The decline in nonperforming assets was spread broadly across most product lines and the company continued to take advantage of market opportunities to reduce specific credit risk exposures.

The provision for loan and lease losses for the quarter was $113 million versus $118 million in the prior quarter, in line with the company’s previous guidance that the provision would tend to converge with the level of charge offs in the current environment. The allowance for loan and lease losses remained steady at $1.70 billion.

Balance Sheet and Capital Management

Balance sheet growth during the quarter was fueled primarily by the expansion of the home equity loans and lines of credit, multi-family lending and ARM portfolios. At Sept. 30, consolidated assets were $286.72 billion, up 7 percent from $268.30 at Dec. 31, 2002.

At Sept. 30, 2003, balances of transaction deposits, which include checking, savings and money market deposits, represented 81 percent of total deposits, compared with 78 percent at Dec. 31, 2002. Total deposits were $164.14 billion at the end of the third quarter, up from $155.52 billion at Dec. 31, 2002, but down from $166.46 billion at the end of the second quarter. A reduction in custodial deposits during the quarter, reflecting a slowing in home loan refinancing activity, was significantly offset by a continued strong expansion of our retail deposit base.

During the third quarter, the company repurchased 11.6 million shares of its common stock at an average price of $39.25. The company’s tangible common equity was 5.29 percent of total tangible assets at Sept. 30, 2003.

In addition, the capital ratios of the company’s banking subsidiaries continued to exceed federal regulatory requirements for classification as “well-capitalized” institutions, the highest regulatory standard.

Outlook

“Looking ahead, Washington Mutual is well-positioned to achieve its business objectives while progressing toward our long-term goal of building the nation’s leading retailer of financial services to the broad middle market,” Killinger said. “As we progress toward this goal, our management team is focused on delivering increased value to our customers, generating growth in our key businesses and driving greater productivity and efficiency in our operations.”
