SUMMARY

The following summary highlights selected information contained or incorporated by reference in this prospectus. The summary does not contain all of the information that may be important to you or that you should consider when making an investment decision. You should carefully read the summary together with the more detailed information that is contained and incorporated by reference in this prospectus.

PNM Resources, Inc.

We are an energy holding company based in Albuquerque, New Mexico, primarily engaged in the generation, transmission, distribution, sale and marketing of electricity and in the transmission, distribution and sale of natural gas within the States of New Mexico and Texas. Our business is currently conducted through our subsidiaries, Public Service Company of New Mexico, or PNM, Texas-New Mexico Power Company, or TNMP, and First Choice Power, or FCP.

PNM is New Mexico's largest electricity and natural gas provider, serving approximately 413,000 electric and 471,000 natural gas customers throughout the state. As of December 31, 2004, PNM had an integrated portfolio of 2,417 MW of generation, which PNM uses to serve both regulated and unregulated load. Pursuant to a long-standing regulatory approach, PNM uses a joint-dispatch method that serves both retail and wholesale markets. During 2004, our sales in the wholesale electric market accounted for approximately 62% of total MWh sales, of which 80% had been purchased for resale. For the year ended December 31, 2004, we generated approximately $1.6 billion in operating revenues, with approximately $659.5 million in gross margin (which is operating revenues less cost of energy sold) representing 41.1% of operating revenues. Of those amounts, our unregulated wholesale business generated approximately $588.2 million in operating revenues, with approximately $96.4 million in gross margin representing 16.4% of operating revenues, while our regulated electric and gas businesses generated approximately $1.1 billion in operating revenues, with approximately $562.3 million in gross margin representing 51.9% of operating revenues. PNM's utility electric distribution system spans more than 4,098 miles of overhead lines and 4,303 miles of underground cable lines while the gas transmission system stretches about 1,545 miles and the distribution system consists of approximately 11,841 miles of pipe.

On June 6, 2005, we completed our acquisition of all the outstanding common shares of TNP.  TNP was a privately owned holding company for Texas-New Mexico Power Company and First Choice Power.  TNMP provides electric service to approximately 256,000 customers in Texas and New Mexico.  Its affiliate, First Choice, is a retail-electric provider with approximately 56,000 customers in Texas.  For more detailed information concerning the TNP acquisition, you should also read "Management's Discussion and Analysis of Financial Conditions and Results of Operations" and the Notes to Consolidated Financial Statements contained in certain of the documents incorporated by reference in this prospectus.

Our executive offices are located at Alvarado Square, Albuquerque , New Mexico 87158, and our telephone number at that address is (505) 241-2700.

This Offering

We agreed to file with SEC the registration statement of which this prospectus forms a part to afford the selling stockholders identified herein the opportunity to resell the shares of our common stock they received in connection with our acquisition of TNP, described above, in public transactions rather than pursuant to exemptions from the registration and prospectus delivery requirements of the Securities Act of 1933, as amended, or the Securities Act.

Subject to the lock-up agreements discussed herein under "Plan of Distribution", the selling stockholders identified in this prospectus may sell up to 4,326,337 shares of our common stock in public or private transactions, or both.  These sales may occur at fixed prices that are subject to change, at prices that are determined by prevailing market prices, or at negotiated prices.  The selling stockholders may sell their shares from time to time to or through broker-dealers, who may receive compensation in the form of discounts, concessions or commissions from the selling stockholders, the purchasers of the shares, or both.  For information on the methods of sale of the common stock, you should read the section of this prospectus entitled "Plan of Distribution" on page 3.

We will not receive any of the proceeds from the sale of shares by the selling stockholders.

USE OF PROCEEDS

We will not receive any of the proceeds from the sale by the selling stockholders of the shares of common stock. All proceeds from the sale of the common stock under this prospectus will be for the account of the selling stockholders, as described below. See "Selling Stockholders" and "Plan of Distribution" below.

SELLING STOCKHOLDERS

On June 6, 2005, we completed our acquisition of all the outstanding common shares of TNP.  Under the terms of the acquisition agreement, TNP's common shareholder received 4,326,337 of our newly issued common shares and cash in an amount at closing equal to approximately $87.6 million, which constituted the estimated purchase price that is subject to certain post-closing adjustments.  We understand that most of the 4,326,337 shares of common stock were subsequently distributed to the partners of TNP's common shareholder, which we refer to herein as the selling shareholders.  This prospectus covers the resale by the selling stockholders of up to the 4,326,337 shares of our common stock issued in connection with the acquisition.

The following table sets forth the names of the selling stockholders, information as of November 10, 2005 regarding the beneficial ownership of common stock by each of the selling stockholders and the number of shares of our common stock that may be offered by each selling stockholder under this prospectus.  Information with respect to the beneficial ownership is based upon information from the selling stockholders or agents of the selling stockholders.  Information with respect to the number of shares beneficially owned after the offering assumes the sale of all of the shares offered by the selling stockholders under this prospectus and no other purchases or sales of common stock.  The applicable percentages of beneficial ownership after the offering is based on an aggregate of 68,763,951 shares of our common stock issued and outstanding as of November 11, 2005.  Other than as described above, none of the selling stockholders listed in the table have held any position or office or have had a material relationship with us or any of our affiliates within the past three years.  None of the selling stockholders who are affiliates of broker-dealers acquired the shares outside the ordinary course of business or, at the time of the purchase of the shares, had any agreements, plans or understandings, directly or indirectly, with any person to distribute the shares.

PLAN OF DISTRIBUTION

Certain of the selling stockholders have entered into lock-up agreements, described below in this section, under which they have agreed not to sell their shares for specified periods of time.

Subject to the terms of the lock-up agreements, the selling stockholders may, from time to time, sell any or all of their shares of common stock offered under this prospectus. The selling stockholders will act independently of us in making decisions with respect to the timing, manner and size of each sale of shares of common stock covered by this prospectus. We will not receive any of the proceeds of the sale of the common stock offered by this prospectus.

The common stock offered by this prospectus may be sold from time to time to purchasers:

The selling stockholders and any underwriters, broker-dealers or agents that participate in the distribution of the common stock may be deemed to be "underwriters" within the meaning of the Securities Act. As a result, any profits on the sale of the shares by selling stockholders and any discounts, commissions or agent's commissions received by any such broker-dealers or agents may be deemed to be underwriting discounts and commissions under the Securities Act. Selling stockholders who are "underwriters" within the meaning of the Securities Act will be subject to prospectus delivery requirements of the Securities Act. If the selling stockholders were deemed to be underwriters, the selling stockholders may be subject to certain statutory liabilities of the Securities Act and the Exchange Act. If the shares are sold through underwriters, broker-dealers or agents, the selling stockholders will be responsible for underwriting discounts or commissions or agent's commissions.

The common stock may be sold in one or more transactions at:

These sales may be effected in one or more transactions:

These transactions may include block transactions or crosses. Crosses are transactions in which the same broker acts as an agent on both sides of the trade.

In connection with the sales of the common stock, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions that in turn may engage in short sales of the common stock in the course of hedging their positions, sell the common stock short and deliver the common stock to close out short positions, loan or pledge common stock to broker-dealers or other financial institutions that in turn may sell the common stock, enter into option or other transactions with broker-dealers or other financial institutions that require the delivery to the broker-dealer or other financial institution of the common stock, which the broker-dealer or other financial institution may resell pursuant to the prospectus, or enter into transactions in which a broker-dealer makes purchases as a principal for resale for its own account or through other types of transactions.

We are not aware of any plans, arrangements or understandings between any selling stockholders and any underwriter, broker-dealer or agent regarding the sale of the common stock by the selling stockholders.

There can be no assurance that any selling stockholder will sell any or all of the common stock pursuant to this prospectus. Further, we cannot assure you that any such selling stockholder will not transfer, devise or gift the common stock by other means not described in this prospectus. In addition, any common stock covered by this prospectus that qualify for sale pursuant to Rule 144 of the Securities Act may be sold under Rule 144 rather than under this prospectus. The common stock may be sold in some states only through registered or licensed brokers or dealers. In addition, in some states the common stock may not be sold unless they have been registered or qualified for sale or an exemption from registration or qualification is available and complied with.

The selling stockholders and any other person participating in the sale of the common stock will be subject to the Exchange Act. The Exchange Act rules include, without limitation, Regulation M, which may limit the timing of purchases and sales of any of the common stock by the selling stockholders and any other such person. In addition, Regulation M may restrict the ability of any person engaged in the distribution of the common stock to engage in market-making activities with respect to the common stock being distributed. This may affect the marketability of the common stock and the ability of any person or entity to engage in market-making activities with respect to the common stock.

Certain of the selling stockholders, namely SW I Acquisition GP, L.P., Continental Casualty Company, CIBC WG Argosy Merchant Fund 2, L.L.C., Caravelle Investment Fund, L.L.C., American Securities Partners II, L.P. and Laurel Hill Capital Partners, L.L.C., who, directly or indirectly, acquired in the aggregate 4,048,801 shares of common stock in connection with our acquisition of TNP, have agreed ("lock-up agreements") not to directly or indirectly sell, offer, contract or grant any option to sell, pledge, transfer or otherwise dispose of any of the shares of our common stock acquired by such selling stockholders in connection with our acquisition of TNP for a certain period of time.  Such lock-up agreements have lapsed with respect to 50% of such shares of common stock and will remain in effect until December 6, 2005, with respect to the remaining 50%, or 2,024,401 shares, of such common stock.

We and the selling stockholders have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act.

We have agreed to pay all expenses incidental to the registration of the common stock offered under this prospectus, including our own legal and accounting fees, transfer agent fees, and the expenses of preparing, printing and filing the registration statement, this prospectus and any prospectus supplement.  The selling stockholders have agreed to pay all other costs associated with the sale of the common stock offered under this prospectus, including all commissions, fees and discounts of underwriters, brokers, dealers and agents, all transfer taxes and related expenses and all fees and costs of their own counsel.

If required, we will distribute a supplement to this prospectus to describe any material changes in the offering.

VALIDITY OF SECURITIES

The validity of the offered securities has been passed upon for us by Charles L. Moore, Associate General Counsel, SEC Reporting and Corporate Transactions, PNM Resources, Inc.

EXPERTS

The consolidated financial statements, related financial statement schedules, and management's report on the effectiveness of internal control over financial reporting incorporated in this prospectus by reference from PNM Resources Inc.'s Current Report on Form 8-K dated September 26, 2005 have been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their reports, which are incorporated herein by reference (which reports (1) express an unqualified opinion on the financial statements and financial statement schedules and include explanatory paragraphs regarding the adoption of Statement of Financial Accounting Standards No. 143, Accounting for Asset Retirement Obligations, effective January 1, 2003, and a change in actuarial valuation measurement date for the pension and other post-retirement benefit plans from September 30 to December 31, (2) express an unqualified opinion on management's assessment regarding the effectiveness of internal control over financial reporting, and (3) express an unqualified opinion on the effectiveness of internal control over financial reporting), and have been so incorporated in reliance upon the reports of such firm given upon their authority as experts in accounting and auditing.

With respect to the unaudited interim financial information for the periods ended March 31, 2005 and 2004 which is incorporated herein by reference, Deloitte & Touche LLP, an independent registered public accounting firm, have applied limited procedures in accordance with the standards of the Public Company Accounting Oversight Board (United States) for a review of such information.  However, as stated in their report included in the Company's Quarterly Report on Form 10-Q for the quarter ended March 31, 2005 and incorporated by reference herein, they did not audit and they do not express an opinion on that interim financial information.  Accordingly, the degree of reliance on their reports on such information should be restricted in light of the limited nature of the review procedures applied.  Deloitte & Touche LLP are not subject to the liability provisions of Section 11 of the Securities Act of 1933 for their reports on the unaudited interim financial information because those reports are not "reports" or "part" of the registration statement prepared or certified by an accountant within the meaning of Sections 7 and 11 of the Act.
