NEWS RELEASE

WASHINGTON BANKING COMPANY REPORTS EARNINGS UP 15% YTD;
LOAN GROWTH AND CREDIT QUALITY REMAIN STRONG

OAK HARBOR, WA – July 25, 2006 – Washington Banking Company (Nasdaq: WBCO) today reported good net income growth for the second quarter and first half of 2006. The holding company for Whidbey Island Bank recorded strong loan growth and improved credit quality from already solid levels. For the quarter ended June 30, 2006, net income increased 6% to $2.5 million, or $0.33 per diluted share, compared to $2.3 million, or $0.31 per diluted share in the second quarter a year ago. For the six-month period, net income grew 15% to $5.0 million, or $0.67 per diluted share, from $4.4 million, or $0.58 per diluted share in the first half of 2005.

“Northwestern Washington State is one of the most demographically desirable markets in the country, with continued population growth fueling a strong economy,” stated Michal Cann, President and CEO. “Loan demand for consumer and commercial projects remains healthy.”

FINANCIAL HIGHLIGHTS

Second quarter 2006 highlights, compared to the same period last year, include:

	•		Net income increased 6% to $2.5 million.

	•		Total loans were up 12% to $686.1 million.

	•		Total deposits grew 9% to $679.9 million.

	•		Nonperforming assets to total assets improved to 0.14% from 0.49%.

	•		Return on average equity was 16.44%, return on average assets was 1.34%.

	•		The efficiency ratio improved to 58.25%.

At June 30, 2006, total loans had increased 12% to $686.1 million, compared to $610.7 million a year earlier. “The strongest loan demand continues to be for real estate and construction loans, and that represents the bulk of the year-over-year growth in our portfolio,” Cann said. “Borrowers recognize our expertise in the market and appreciate our commitment to customer service. While we are confident that we’ll have ample opportunities to continue to grow our portfolio without sacrificing credit quality, we don’t expect to continue at the pace we saw in the second quarter.”

“The loan portfolio continues to perform well, with nonperforming loans and nonperforming assets both declining,” stated Rick Shields, Senior Vice President and Chief Financial Officer. At end of June 2006, nonperforming loans (NPLs) declined to $1.1 million, or 0.16% of total loans, compared to $1.6 million, or 0.25% of total loans at the end of the preceding quarter and $2.6 million, or 0.42% of total loans at the end of the second quarter last year. The bank had no other real estate owned on its books at the end of June or March 2006, down from $870,000 at the halfway point last year. As a result, nonperforming assets were 0.14% of total assets at June 30, 2006, compared to 0.22% three months earlier and 0.49% of total assets at the end of June 2005.

“Net loan charge-offs increased in the June quarter when compared to the previous quarter, but primarily as a result of the exceptionally high level of recoveries in the first quarter of this year,” Shields said. “The loan loss provision, however, has kept pace with the growth in the loan portfolio and our coverage ratio remains at 1.40% of total loans.” The loan loss provision was $800,000 in the second quarter of 2006 and $1.3 million year-to-date, compared to $525,000 and $950,000, respectively, last year. The reserve for loan losses has grown to $9.6 million as of June 30, 2006.

“The continued rise in interest rates has helped our loan yields,” Cann said. “However, the rate environment coupled with an extremely competitive market has also driven up our funding costs.” On a fully tax-equivalent basis, the net interest margin was 5.37% in the second quarter, down from 5.59% in the March quarter, but up slightly from 5.32% a year ago.

“Unusually high first quarter interest recoveries essentially inflated our net interest margin by roughly eight basis points, so the sequential-quarter erosion is not as large as it first appears,” Shields said. “In fact, our margin has actually improved on a year-over-year basis to 5.47%, compared to 5.27% in the first half of last year. Looking toward year-end, I expect some additional erosion in our net interest margin, but not as dramatic as seen in the most recent quarter.”

“Growing our low-cost deposit base is a priority, but it is challenging in the current environment,” Cann said. At the end of June 2006, total deposits were $679.9 million, up 9% from $623.0 million at the end of the second quarter 2005. Low-cost deposits grew by $8.9 million over the past year to $403.1 million, while time deposits increased by $48.0 million in the same time period to $276.8 million at June 30, 2006.

Net interest income was $9.2 million in the quarter ended June 30, 2006, up 11% from $8.3 million in the second quarter last year. For the six-month period ended June 30, net interest income was $18.3 million in 2006, up 14% from $16.1 million in the same period last year. Noninterest income was $1.7 million in the 2006 second quarter, compared to $1.9 million in the second quarter of 2005; noninterest income increased slightly in the six-month period to $3.6 million, from $3.5 million in 2005.

“While service charges have shown solid growth, our annuity sales and SBA premiums declined in the second quarter,” Cann said. “In addition, gain on sale of mortgage loans also decreased. It’s anticipated that annuities and SBA premiums will pick back up in the second half, although our 2006 noninterest income will not likely improve substantially over last year’s level.”

Noninterest expense was up 4% to $6.4 million in the 2006 second quarter, from $6.2 million in the same quarter last year. For the first half of 2006, noninterest expense was $13.1 million, up 8% from $12.1 million in the first half of last year.

“The increase in second quarter operating expenses was quite moderate compared with last year, and expenses were actually lower on a sequential quarter basis,” said Shields. “However, some additional expenses are expected in the second half of the year due to the opening of our fourth Bellingham branch scheduled for late September.”

The efficiency ratio improved to 58.25% in the second quarter of 2006, compared to 59.83% in the same quarter last year. Return on average equity (ROE) was 16.44% in the second quarter of 2006, compared to 18.24% a year ago. Return on average assets (ROA) was 1.34%, versus 1.37% in the second quarter of 2005.

For the six-month period through June, the efficiency ratio was 59.39% in 2006, versus 61.39% last year. ROE was 17.05%, compared to 17.44% in the first half of 2005, and ROA improved to 1.39%, from 1.32% in the six-month period ended June 30, 2005.

⁽¹⁾ Revenues is the fully tax-equivalent net interest income before provision for loan losses plus noninterest income.

⁽²⁾ Fully tax-equivalent is a non-GAAP performance measurement that management believes provides investors with a more accurate picture of the net interest margin, revenues and efficiency ratio for comparative purposes. The calculation involves grossing up interest income on tax-exempt loans and investments by an amount that makes it comparable to taxable income.
