2010 FINANCIAL RESULTS

SPOKANE, WASHINGTON - AmericanWest Bancorporation (OTCBB: AWBC) today announced first quarter 2010 financial results, which included the following:

• First quarter 2010 net interest margin was 3.62%, up 8 basis points from the previous quarter and up 31 basis points over the first quarter of 2009.

• Non-performing assets at March 31, 2010 decreased by $11.5 million, or 7%, as compared to the prior quarter.

• Net charge-offs for the first quarter of 2010 were $5.5 million as compared to $9.8 million for the fourth quarter of 2009 and $17.7 million for the first quarter of 2009.

• Provision for loan losses was $5.0 million for the first quarter of 2010 as compared to $15.9 million for the fourth quarter of 2009 and $13.7 million for the first quarter of 2009. This is the lowest provision for loan losses recorded since the third quarter of 2007.

• Total balance sheet liquidity (comprised of cash, cash equivalents and securities) at March 31, 2010 declined to $229.6 million, as compared to $250.6 million at December 31, 2009, and increased significantly from $129.9 million at March 31, 2009.

• Loans ended the quarter at $1.19 billion, a reduction of $78 million, or 6%, from December 31, 2009 and a reduction of $369 million, or 24%, over the past year.

• Total deposits declined by 6% to $1.41 billion at March 31, 2010 as compared to $1.51 billion at December 31, 2009.

• Total non-interest expense for the first quarter of 2010 included $2.7 million of foreclosed property expense, including $1.2 million of valuation adjustments, as compared to expense of $15.2 million for the fourth quarter of 2009, including $13.0 million of valuation adjustments.

For the quarter ended March 31, 2010, AmericanWest Bancorporation (Company) reported a net loss of $8.5 million, or $0.50 per share, as compared to a net loss of $17.7 million, or $1.03 per share, for the fourth quarter of 2009 and a net loss of $14.5 million, or $0.84 per share, for the first quarter of 2009. “Our first quarter financial results were in line with our expectations, with marked improvement in the key areas of margin expansion, credit costs and non-interest expense,” remarked Patrick Rusnak, Chief Executive Officer. “Although additional work lies ahead of us on the road back to profitability, it appears that the real estate market and economic headwinds that have challenged us for the past two years are finally subsiding, and our key performance indicators are moving in the right direction. Credit for our progress is, of course, also due to our dedicated staff and loyal customers.”

Net Interest Margin:

The tax-equivalent net interest margin for the first quarter of 2010 was 3.62%, up 8 basis points from the fourth quarter of 2009 and 31 basis points from the first quarter of 2009, principally driven by a reduction in the average cost of deposits.

The average yield on loans for the first quarter was 5.84%, an increase of 3 basis points from the prior quarter, and an increase of 20 basis points from the same period in 2009. The loan yield for the first quarter of 2010 was reduced by 64 basis points due to the total impact of non-accrual loans, including both reversed and forgone interest as compared to 50 basis points in the fourth quarter of 2009.

The average cost of interest bearing deposits for the first quarter was 1.49%, a decrease of 17 basis points from the fourth quarter of 2009 and a decrease of 102 basis points from the first quarter of 2009. The cost of borrowed funds, including FHLB advances and junior subordinated debt, was 4.54% for the first quarter of 2010, an increase of 20 basis points from the fourth quarter of 2009, and an increase of 135 basis points from the first quarter of 2009, due mainly to the mix of borrowings. The average cost of interest bearing liabilities for the first quarter of 2010 was 1.75%, as compared to 1.88% for the fourth quarter of 2009 and 2.61% for the first quarter of 2009. The Company’s cost of funds inclusive of non-interest bearing deposits was 1.42% for the first quarter of 2010 as compared to 1.53% for the fourth quarter of 2009, and 2.17% for the same period of 2009.

Loans:

Total outstanding loans as of March 31, 2010 were $1.19 billion, as compared to $1.27 billion at December 31, 2009, and $1.56 billion at March 31, 2009. The linked-quarter reduction was principally driven by a decline of $34.6 million in construction and development loans (including $9.5 million transferred to foreclosed real estate and $2.0 million in charge-offs). Total average loans outstanding for the first quarter of 2010 were $1.23 billion, a decrease of $108.3 million from the prior quarter and $383.9 million the same period in 2009.

Asset Quality:

Total non-performing assets, net of government guarantees on loans, were 9.45% of total assets at March 31, 2010 as compared to 9.58% of total assets at December 31, 2009, and 7.96% of total assets at March 31, 2009. Non-performing loans, net of government guaranteed amounts, represented 7.44% of total loans at March 31, 2010 as compared to 8.28% of total loans at December 31, 2009 and 7.86% of total loans at March 31, 2009. Non-performing loans reported as of March 31, 2010 reflected cumulative charge-offs of $19.6 million, of which $3.0 million were recognized during the quarter ended March 31, 2010. The decrease in non-performing loans during the first quarter is due mainly to paydowns of $10.8 million and loans transferred to foreclosed assets of $10.8 million. Foreclosed property at March 31, 2010 totaled $58.3 million and consisted of 47 properties, as compared to $53.4 million (45 properties) at December 31, 2009, and $22.6 million (28 properties) as of March 31, 2009. During the first quarter of 2010, 12 foreclosed properties with an aggregate carrying value of $4.7 million were sold, resulting in a pre-tax loss of $169 thousand. In addition, during the first quarter of 2010, $1.2 million of impairment charges were recognized on foreclosed real estate based upon updated appraisals or adjustments in listing prices resulting from observed market conditions. The $58.3 million carrying value of foreclosed property as of March 31, 2010 was net of $78.4 million of previously recorded loan charge-offs and valuation adjustments. Foreclosure action has been initiated on substantially all real estate secured non-performing loans, and the Company expects to obtain ownership of approximately $10.5 million of additional real estate collateral during the second quarter of 2010.

At March 31, 2010, the Company had approximately $93.1 million of loans, net of government guarantees, which were not classified as non-performing but were internally identified as potential problem loans due to management’s concerns about the borrower’s financial condition. This represented approximately 7.8% of total outstanding loans, as compared to 6.3% at December 31, 2009. “We have seen a substantial increase in the level of buyer interest for our larger problem loans and foreclosed properties during the past few weeks, including large residential development projects for which demand had previously been very limited,” commented Rusnak. “With approximately 20% of our OREO currently under contract for sale and a dramatic decline in the volume of loans being moved to non-accrual status, we are expecting a significant reduction in the level of non-peforming assets during the second quarter and balance of 2010.”

The Company recognized a first quarter 2010 provision for loan losses of $5.0 million or 1.65% of average loans on an annualized basis, as compared to $15.9 million, or 4.70% of average loans on an annualized basis, for the quarter ended December 31, 2009. For the quarter ended March 31, 2009, the Company recognized a provision for loan losses of $13.7 million, or 3.44% of average loans on an annualized basis. For the quarter ended March 31, 2010, net charge-offs were $5.5 million, or 1.81% of average loans annualized, as compared to $9.8 million, or 2.92% of average loans annualized, for the quarter ended December 31, 2009 and $17.7 million, or 4.45% of average loans annualized, for the first quarter of 2009.

It is the Company’s general policy to recognize as charge-offs any specific loan impairments for known losses in lieu of carrying such amounts as a specific component of the allowance for credit losses. The allowance for credit losses, which is comprised of the allowance for loan losses and reserve for unfunded commitments, was $38.9 million, or 3.26% of total loans at March 31, 2010, an increase of 16 basis points from December 31, 2009 and an increase of 61 basis points from March 31, 2009. Included in the allowance for loan losses at March 31, 2010 was $3.6 million of specific reserves associated with four loan relationships.

Deposits and Liquidity:

Total average interest bearing deposits for the first quarter of 2010 were $1.16 billion as compared to $1.25 billion in the fourth quarter of 2009 and $1.22 billion in the first quarter of 2009. Total average non-interest bearing demand deposits for the first quarter of 2010 were $295.1 million, a decrease of $7.9 million, or 3% as compared to the fourth quarter of 2009, and substantially unchanged from the same period of the prior year. Total average interest bearing demand deposit balances decreased $33.9 million, or 15% during the first quarter and increased $58.1 million, or 44%, since March 31, 2009 due mainly to promotional campaigns. The average savings and MMDA deposits decreased $20.0 million, or 5% as compared to the fourth quarter of 2009, and decreased $69.3 million, or 16% as compared to the first quarter of 2009. The average balance of certificates of deposit decreased $39.0 million, or 6%, as compared to the fourth quarter of 2009 and decreased $54.1 million, or 8%, as compared to the first quarter of 2009. The decrease in certificates of deposit from the first quarter of the prior year was principally the result of a reduction in brokered certificates of $25.0 million which matured during first half of 2009.

Total deposits as of March 31, 2010 were $1.41 billion, a decrease of 6% from December 31, 2009 and a decrease of 8% from March 31, 2009. Total brokered certificates of deposit at March 31, 2010 were $2.5 million, unchanged from December 31, 2009.

The reduction in loans, both through principal repayments and collateral liquidation, and the continued stability of the core deposit base have reduced the Company’s reliance on borrowings to fund its liquidity needs over the past year. Total FHLB and other borrowings at March 31, 2010 were $68.7 million, an increase of $5.0 million from December 31, 2009 and a decrease of $75.1 million from March 31, 2009.

As of March 31, 2010, the Bank had total available secured borrowing capacity of approximately $167.7 million through facilities at the FHLB and the Federal Reserve Bank of San Francisco (Fed) Discount Window program. As of March 31, 2010, the Bank had no borrowings from the Fed Discount Window.

Non-interest Income:

Non-interest income for the first quarter of 2010 was $2.8 million, as compared to $3.5 million for the fourth quarter of 2009 and $5.8 million for the first quarter of 2009. Fees and service charges on deposits income was $2.1 million, a decrease of $173 thousand as compared to the fourth quarter and a decrease of $105 thousand as compared to the first quarter of 2009. The declines as compared to the fourth and first quarters of 2009 are due mainly to lower overdraft fees in the first quarter of 2010. Fees on mortgage loan sales were $538 thousand, a decrease of $468 thousand from the preceding quarter and $1.4 million as compared to the first quarter of 2009, due to lower volumes of mortgages originated and sold. Other non-interest income was $197 thousand for the first quarter of 2010, an increase of $25 thousand as compared to the fourth quarter of 2009 and a decrease of $1.5 million as compared to the first quarter of 2009. Included in other non-interest income for the first quarter of 2009 was an excise tax refund from the state of Washington of $977 thousand, net of certain professional fees, paid in the process of amending prior years’ excise tax returns and $535 thousand of income related to the sale of a merchant bankcard portfolio, which was partially offset by losses on disposals of leasehold improvements of $419 thousand. In addition to these non-interest items, net gains from the sale of foreclosed assets declined $103 thousand in the first quarter of 2010 as compared to the first quarter of 2009 and merchant bankcard portfolio revenue declined $98 thousand.

Non-interest Expense:

Non-interest expense for the first quarter of 2010 was $19.3 million, as compared to $32.3 million for the fourth quarter of 2009 and $20.6 million for the first quarter of 2009. Foreclosed assets expense for the first quarter of 2010 was $2.7 million, a decrease of $12.4 million as compared to the fourth quarter of 2009. The decline is related to $13.0 million of valuation adjustments recorded in the fourth quarter of 2009 based upon updated appraisals and other considerations. Similar adjustments in the first quarter of 2010 totaled $1.2 million. Foreclosed assets expense was $617 thousand for the first quarter of 2009. Other non-interest expenses for the first quarter of 2010 declined $978 thousand as compared to the fourth quarter of 2009 and were $380 thousand less than the similar period of the prior year. The reduction from the fourth quarter of 2009 is due to decreases in other operational losses ($288 thousand), other expenses ($225 thousand), loan expenses ($203 thousand) and provision for unfunded commitments ($100 thousand). These decreases are partially offset by an increase in other professional fees associated with regulatory compliance and capital raising efforts of $101 thousand. Salaries and employee benefits expense for the first quarter of 2010 was $8.1 million, up $468 thousand (6%) from the fourth quarter of 2009 and down $825 thousand (9%) from the same period in 2009. The increase in salaries and employee benefits as compared to the preceding quarter is mainly due to benefit costs increasing $386 thousand. The decrease in salaries and employee benefits as compared to the first quarter of 2009 is mainly related to cost saving initiatives.

The efficiency ratio for the quarter ended March 31, 2010 was 101%, as compared to 95% in the prior quarter and 98% for the similar quarter of the prior year.

Income Taxes:

As a result of the Company’s going concern status, since December 31, 2008, all tax benefits from operating losses have been deferred and all deferred taxes have been fully reserved. The ability of the Company to recognize any tax benefit from its deferred tax assets in the future, even if it is successful in raising additional capital and attaining future operating profitability, will be limited by the current Internal Revenue Code and is not expected to provide a material positive impact on the regulatory capital ratios of the Company or Bank. During the quarter ended December 31, 2009, the Company recorded a tax benefit of $13.2 million based upon a recently enacted tax law change that extended the net operating loss carry-back period to five years, subject to certain limitations.

Capital and Regulatory Matters:

At March 31, 2010, total stockholders’ equity was $11.2 million and total tangible stockholders’ equity was $1.2 million, or $0.07 per share. The Company’s tangible equity ratio (tangible equity divided by tangible assets) was 0.08% as of March 31, 2010. At March 31, 2010, the Bank was classified as “significantly undercapitalized” for regulatory capital purposes. The Company and Bank’s regulatory capital ratios as of March 31, 2010 are included in the financial tables accompanying this release.

“Since the engagement of Cappello Capital as a new financial advisor two months ago, significant progress has been made with introducing new prospective private investors to the AmericanWest opportunity and reconnecting with those already familiar with our bank,” remarked Rusnak. “We are intently focused on completion of a recapitalization during the second quarter. We believe that improvements in capital markets conditions and the economic outlook, and evidence that progress is being made with our asset quality and operating performance, combined with our solid core deposit base, give us the basis for optimism on our ability to resolve the current capital deficiency and related regulatory directives.”

On February 24, 2010, the FDIC issued a Supervisory Prompt Corrective Action Directive directing the Bank to recapitalize within 30 days of receipt, and reiterating various requirements already imposed on the Bank by the Order described below.

On September 15, 2009, the Company entered into a Written Agreement with the Federal Reserve Bank of San Francisco. Substantially all of the requirements of the Written Agreement are similar to requirements imposed on the Company and the Bank pursuant to other regulatory agreements, and the Company and the Bank have been operating in a manner consistent with those requirements.

On May 11, 2009, AmericanWest Bank, the wholly-owned operating subsidiary of the Company (Bank), stipulated to entry of an Order to Cease and Desist (Order) by the FDIC and the Washington Department of Financial Institutions, Division of Banks. Management believes the Bank is in compliance with all but two provisions contained in the Order. First, the Bank did not attain the required Tier 1 leverage capital ratio of 10% within the required 120 day period, which expired on September 8, 2009. The amount of additional capital required to attain the prescribed Tier 1 leverage ratio as of March 31, 2010 was approximately $114.7 million (please refer to the Consolidated Financial Highlights section of this release for additional information on regulatory capital ratios). Second, the ratio of assets classified as substandard or doubtful noted in the most recent report of examination was not reduced to the required level of 75% of capital by September 8, 2009. The respective ratio was 114% as of March 31, 2010. Although the amount of assets so classified has been reduced by $131.0 million since December 31, 2008, the decrease in the Bank’s regulatory capital resulting from operating losses has impeded the Bank’s ability to achieve the requirements of this provision within the specified timeframe.
