Filed by: Public Service Company of New Mexico pursuant to Rule 425 under the Securities Act of 1933 and deemed filed pursuant to Rule 14a-12 ------------------------------------------------ of the Securities Exchange Act of 1934 -------------------------------------- Public Service Company of New Mexico Commission File No.: 1-6986 ----------------------------------------------------------------- Western Resources, Inc. Commission File No.: 1-3523 ---------------------------------------------------- Subject Company: Western Resources, Inc. May 16, 2001 Dear Fellow Shareholder, PNM revenues and earnings for the first quarter of 2001 were substantially higher than for the same period last year. Earnings per share for the first three months of this year were $1.60 per share (diluted), compared to earnings of 55 cents per share in the first quarter of 2000. Driven by high wholesale prices, revenues from our wholesale business more than tripled during the first quarter compared to the same period last year. We expect the present imbalance of supply and demand will continue to affect wholesale prices in the Western U.S. at least through the remainder of the year. Federal regulators have placed some limited price controls on wholesale sales in California, and other more restrictive measures are being debated both in Congress and in the California Legislature. While it is difficult to accurately forecast what the impact of regulatory or legislative actions may be on prices in the short term, only the addition of new generating capacity and increased efficiency of electricity use in the region will finally ease the upward pressure on prices. While PNM today has adequate power to meet our needs, we are preparing to meet the future needs of our growing communities and expand our presence in the Western wholesale market. The 132-megawatt Delta-Person plant south of Albuquerque has been in operation since last summer, and we have more natural gas-fired turbines on order for future projects. Since 1993, your company has invested about $36 million to stabilize and expand the PNM transmission system. In May we launched "Project Power," a coordinated campaign to encourage broad public participation in planning to serve the needs of PNM customers in north-central New Mexico. To learn more about that community effort, please visit the new Project Power web site at www.project-power.org Although New Mexico has postponed the opening of retail electric competition here until 2007, we are moving forward with our plans to establish a new holding company, complete our proposed acquisition of Western Resources' electric utility operations, and position our company for continued success. I hope you will be able to attend the PNM annual shareholders meeting on July 3 in the Albuquerque Convention Center. Thank you for your continued confidence in PNM. Sincerely, Jeff Sterba Chairman, President And Chief Executive Officer Safe Harbor Statement under the Private Securities Litigation Reform Act of 1995 Statements made in this letter that relate to future events are made pursuant to the Private Securities Litigation Reform Act of 1995.

Because actual results may differ materially from expectations, the company cautions readers not to place undue reliance on these statements.
