Sierra Pacific Resources Moves to Strengthen Balance Sheet and Liquidity

RENO, Nev.
Feb 3, 2003

Sierra Pacific Resources (NYSE: SRP) today announced that it has reached agreements to exchange 30% of its mandatorily convertible securities into common stock as part of its strategy to strengthen the Company's balance sheet and liquidity. The exchange of these securities -- known as Premium Income Equity Securities (PIES) -- effectively accelerated their conversion.

As a result, Sierra Pacific Resources will reduce its outstanding parent company debt by approximately $105 million. Additionally, it will reduce by approximately $26 million the interest expense that would have been paid to PIES holders by Sierra Pacific Resources through the November 2005 conversion date. The exchanges were executed at a substantial discount to the PIES stated value.

Under the terms of the privately negotiated agreements reached with a limited number of investors, Sierra Pacific Resources will issue approximately 13.66 million shares of common stock in exchange for a total of 2,095,650 of the mandatorily convertible securities. The exchanges are expected to settle February 5, 2003. The Company has no plans to retire additional outstanding securities through the issuance of common stock.

Walter Higgins, chairman, president and CEO of Sierra Pacific Resources, said, "This is a significant development in strengthening our financial position. During the first quarter of this year, we intend to pursue further actions that will continue to improve our balance sheet and liquidity. Those actions will be announced promptly as they occur."

The PIES exchanges accelerate by two years and 10 months the conversion of approximately 30% of the outstanding securities, which were mandatorily convertible into approximately 7.6 million common shares. Any incremental dilution resulting from these exchanges is significantly mitigated by the combination of interest savings and a 30% discount from the PIES' stated value.
