ZIONS BANCORPORATION REPORTS 2003 FIRST

QUARTER EARNINGS OF $0.97 PER DILUTED SHARE

SALT LAKE CITY, April 17, 2003 – Zions Bancorporation (“Zions” or “the Company”) (Nasdaq: ZION) today reported first-quarter net income of $87.7 million, or $0.97 per diluted share. Net income for the first quarter of 2002 was $47.3 million, or $0.51 per share. Net income for the first quarter of 2002 included an adjustment of $32.4 million ($0.35 per share) that reduced earnings for the cumulative effect of an accounting change resulting from the adoption of SFAS No. 142 and a loss from discontinued operations of $3.2 million ($0.03) per share. Income from continuing operations was $87.4 million, or $0.96 per diluted share, for the first quarter of 2003, an increase of 5.5% and 7.9%, respectively, over income from continuing operations of $82.8 million, or $0.89 per share for the first quarter of 2002.

“We are pleased to again report a solid quarter with no major unusual items,” said Harris H. Simmons, Chairman and Chief Executive Officer. “We are particularly pleased with the progress made on reducing the expense-to-revenue ratio, and in managing the net interest margin during a period of low interest rates and continued deposit inflows. Although loan growth was slow during the quarter, this was not unexpected, and we are pleased with our continued strong credit quality performance in a difficult economic environment.”

Loan and Deposit Growth

Loan growth for the quarter was weak reflecting the soft economy and the Company’s caution regarding aggressive loan growth in the current economic environment. On-balance-sheet net loans and leases at March 31, 2003 were $19.1 billion, an increase of 7.2% from March 31, 2002 and an annualized increase of 1.9% from December 31, 2002. On balance sheet and sold loans being serviced were $21.5 billion at March 31, 2003, an increase of 5.7% from March 31, 2002 and an annualized increase of 0.3% from balances reported at year-end.

Deposit growth for the quarter continued to be very strong. Deposits increased 15.6% over the balances reported one year ago to $20.8 billion, and increased 13.3% annualized from balances reported at year-

end 2002. Core deposits, which exclude time deposits $100,000 and over, increased 18.4% year-over-year, and at an annualized rate of 16.2% for the quarter.

Net Interest Income

For the quarter, taxable-equivalent net interest income of $272.0 million increased 4.1% compared to $261.3 million for the first quarter of 2002. For the first quarter of 2003, the net interest margin was 4.54%, compared to 4.41% for the fourth quarter of 2002, and 4.70% for the first quarter of 2002.

Noninterest Income

For the first quarter of 2003, noninterest income increased 2.7% to $96.3 million compared to $93.8 million for the first quarter of 2002. Excluding equity securities gains (losses), noninterest income for the first quarter of 2003 increased 9.7% from the first quarter of 2002. Noninterest income for the first quarter of 2003 includes $6.7 million of losses from investments made by venture capital funds (partially offset by $0.8 million of gains realized on the sale of marketable equity securities) compared to gains of $0.6 million for the first quarter of 2002. Net of minority interest and income taxes, the results of the venture capital funds reduced net income by $3.0 million ($.03 per share) in the first quarter of 2003.

Noninterest Expense

For the first quarter of 2003, noninterest expense was $214.0 million, a decrease of 2.2% from noninterest expense of $218.8 million for the fourth quarter of 2002, and an increase of 4.2% from $205.3 million of noninterest expense for the first quarter of 2002. The efficiency ratio for the first quarter of 2003 was 58.1% compared to 60.0% for the fourth quarter of 2002 and 59.5% for the first quarter of 2002. Excluding discontinued operations, restructuring and impairment charges and amortization of intangibles, the efficiency ratio for the first quarter of 2003 was 57.1% compared to 57.7% for the fourth quarter of 2002. The comparable efficiency ratio for the first quarter of 2002, but including the operations later discontinued, was 58.2%.

Asset Quality

The ratio of nonperforming assets to total loans and other real estate improved to 0.56% at March 31, 2003 compared to 0.61% at December 31, 2002 and 0.73% at March 31, 2002. For the first quarter of 2003, net loan and lease losses were $16.6 million or 0.35% annualized of average loans, compared to $12.5 million or 0.27% annualized for the fourth quarter of 2002 and $14.5 million or 0.33% annualized

for the first quarter of 2002. At $280.5 million on March 31, 2003, the allowance for loan losses was 1.47% of total loans and 315% of nonperforming loans.

Provision for Loan Losses

For the first quarter of 2003, the provision for loan losses was $17.6 million compared to $15.8 million provided during the fourth quarter of 2002 and $18.1 million provided during the first quarter of 2002. The provision reflects management’s evaluation of its various portfolios, statistical trends and other economic factors, and its desire to maintain a strong coverage of nonperforming assets in a continued uncertain economic environment in the markets in which it operates.

Capital Management

During the first quarter of 2003, Zions repurchased 578,480 shares of common stock at an average price of $41.88 per share. As of March 31, 2003, the Company had $3.4 million remaining in its currently authorized share repurchase program. Weighted average common and common equivalent shares outstanding for the first quarter of 2003 were 90,647,613, compared to 91,073,433 for the fourth quarter of 2002 and 92,813,828 for the first quarter of 2002.

The Company’s tangible common equity ratio was 6.07% at March 31, 2003 compared to 6.06% at December 31, 2002 and 6.03% at March 31, 2002.
