Debt Disclosure [Abstract]  
Financing Financing
The Company’s financing strategy includes both short-term and long-term borrowings. The Company utilizes short-term revolving credit facilities, as well as cash flows from operations, to provide funds for both construction and operating expenditures. Depending on market and other conditions, the Company will periodically sell long-term debt, enter into term loan arrangements, or equity arrangements and use the proceeds to reduce borrowings under the revolving credit facilities or refinance other debt. Each of the Company’s revolving credit facilities, term loans, and other debt agreements contains a single financial covenant that requires the maintenance of a debt-to-capitalization ratio. For the TXNM agreements, this ratio must be maintained at less than or equal to 70%, and for the PNM and TNMP agreements, this ratio must be maintained at less than or equal to 65%. The Company’s revolving credit facilities, term loans, and other debt agreements generally also contain customary covenants, events of default, cross-default provisions, and change-of-control provisions. PNM must obtain NMPRC approval for any financing transaction having a maturity of more than 18 months. In addition, PNM files its annual informational financing filing and short-term financing plan with the NMPRC. Additional information concerning financing activities is contained in Note 7 of the Notes to Consolidated Financial Statements in the 2024 Annual Reports on Form 10-K.

On February 28, 2025, TXNM filed a shelf registration that provides for the issuance of various types of debt and equity securities. The TXNM shelf registration statement expires in February 2028.

Financing Activities

On July 31, 2025, PNM entered into an agreement (the “PNM July 2025 Note Purchase Agreement”) with institutional investors for the sale and issuance of $350.0 million aggregate principal amount of two series of SUNs (the “PNM July 2025 SUNs”) offered in private placement transactions. The PNM July 2025 SUNs were issued on July 31, 2025. PNM issued $200.0 million of the PNM July 2025 SUNs at 5.47%, due July 31, 2031, and another $150.0 million at 6.03%, due July 31, 2036. PNM used the proceeds from the PNM July 2025 SUNs to repay the PNM $250.0 million SUNs and for general corporate purposes. The PNM July 2025 Note Purchase Agreement includes the customary covenants discussed above. In the event of a change of control, PNM will be required to offer to prepay the PNM July 2025 SUNs at par. Although there are customary change of control provisions in the PNM debt agreements, the change of control provisions in the agreements, including the PNM July 2025 Note Purchase Agreement, will not be triggered by the closing of the Merger. PNM has the right to redeem any or all of the PNM July 2025 SUNs prior to their maturities, subject to payment of a customary make-whole premium. As PNM demonstrated the intent and ability to refinance the obligation due under the PNM $250.0 million SUNs prior to the issuance of this Form 10-Q, as of June 30, 2025 this has been presented as Long-term Debt on the Condensed Consolidated Balance Sheets.

On July 21, 2025, TNMP entered into an agreement (the “TNMP July 2025 Bond Purchase Agreement”) with institutional investors for the sale of $1,084.3 million aggregate principal amount of six series of TNMP first mortgage bonds (the “TNMP July 2025 FMBs”) offered in private placement transactions. TNMP issued the bonds on July 21, 2025 with the following terms:

The proceeds were used to repay borrowings under the TNMP Merger Backstop Term Loan (defined below). The TNMP July 2025 FMBs are subject to continuing compliance with the representations, warranties, and covenants set forth in the governing supplemental indentures. In the event of certain changes of control of TNMP, TNMP will be required to offer to prepay the TNMP July 2025 FMBs at par. Although there are customary change of control provisions in the TNMP July 2025 FMBs, the change of control provisions will not be triggered by the closing of the Merger. TNMP has the right to redeem any or all of the TNMP July 2025 FMBs prior to their maturity, subject to payment of a customary make-whole premium.
At June 30, 2025, TXNM had a series of treasury lock agreements, with terms ranging from 5 years to 30 years, aggregating a total notional amount of $730.0 million to reduce interest rate exposure on the TNMP July 2025 FMBs that were issued in July 2025. The treasury lock agreements had an average fixed rate of 4.18% and TXNM had designated them as cash flow hedges, measured at fair value, which was recorded as a loss of $2.5 million in Other current liabilities at June 30, 2025. Fair values, provided by an external pricing service, were determined using Level 2 inputs of quoted prices for similar agreements in active markets. On July 1, 2025, TXNM terminated all of the treasury lock agreements, realizing a pre-tax net loss of $1.6 million recorded in Accumulated other comprehensive income. The loss will be amortized through interest expense over a range of 5 to 30 years, in accordance with the terms of the TNMP July 2025 FMBs issued July 21, 2025.

On June 24, 2025, TXNM entered into an agreement (the “June 2025 Purchase Agreement”) whereby TXNM sold, in a private placement transaction, and the purchasers named therein agreed to purchase 3,615,003 shares of TXNM common stock for a purchase price of $55.325 per share (for an aggregate amount of approximately $200 million). The closing of the issuance occurred on June 27, 2025. TXNM used the proceeds to repay an equal amount under the TXNM 2023 Term Loan. TXNM has granted the purchasers customary registration rights with respect to the shares, pursuant to which TXNM is required to register such shares for resale with the SEC no later than five business days after TXNM files this Quarterly Report on Form 10-Q for the quarterly period ending June 30, 2025 (this “Form 10-Q”).

The documents governing an aggregate $1,505.0 million of TNMP’s outstanding FMBs ("TNMP FMBs") obligated TNMP to offer (“the Offer”), within 30 business days following the signing of the Merger Agreement, to prepay all outstanding TNMP FMBs at 100% of the principal amount, plus accrued and unpaid interest thereon, but without any make-whole amount or other premium. On June 14, 2025, the Offer expired and $1,084.3 million in aggregate principal amount of the bonds were validly tendered. TNMP accepted for purchase all validly tendered bonds. On June 24, 2025, holders whose bonds were validly tendered and accepted for purchase received 100% of the aggregate principal amount of bonds prepaid plus accrued and unpaid interest using funds drawn under the TNMP Merger Backstop Term Loan, discussed below. The documents governing the TNMP FMBs currently require TNMP to make another offer, within 30 business days of closing of the Merger, to prepay the remaining outstanding TNMP FMBs, totaling $420.7 million, at par. TNMP will make such offer to prepay the TNMP FMBs in accordance with the terms of the TNMP FMBs; however, holders of the TNMP FMBs are not required to tender their TNMP FMBs and may accept or reject such offer to prepay.

The information in this Form 10-Q is for informational purposes only and is neither an offer to purchase, nor a solicitation of an offer to sell, subscribe for or buy any securities in any jurisdiction pursuant to the proposed transactions or otherwise, nor shall there be any sale, issuance or transfer of securities in any jurisdiction in contravention of applicable law. Similar to the offer to prepay made after signing the Merger Agreement, the post-Merger closing offer to prepay the TNMP FMBs will be made only pursuant to an offer to prepay, which will set forth the terms and conditions of the offer to prepay.

On May 27, 2025, TXNM physically settled all shares under the TXNM 2024 ATM Program by issuing 1,104,641 shares to the forward purchasers, aggregating net proceeds of $49.6 million, including $0.5 million for equity issuance costs. TXNM used the proceeds from the settled shares to repay borrowings under the TXNM Revolving Credit Facility. Following this settlement, no additional shares of TXNM’s common stock remain subject to future settlement under the TXNM 2024 ATM Program.

On May 18, 2025, the execution of the Merger Agreement constituted a “Change of Control” under certain TXNM and TNMP debt agreements. Under each of the specified debt agreements, a “Change of Control” constitutes an “Event of Default,” pursuant to which the lender parties thereto had the right to accelerate the indebtedness under the debt agreements. The definition of Change of Control under the PNM debt agreements and PNM note purchase agreements are not triggered by the execution of the Merger Agreement.

On May 23, 2025, TXNM and TNMP entered into amendments in connection with the TXNM Revolving Credit Facility, TXNM 2023 Term Loan, WFB LOC Facility, and TNMP Revolving Credit Facility with the lender parties thereto (the “Lender Consents”) to (i) amend the definition of "Change of Control" in such agreements such that the entry into the Merger Agreement would not constitute a Change of Control and (ii) waive the Event of Default arising from entry into the Merger Agreement. The amended Change of Control definition under the TXNM and TNMP debt agreements will, however, be triggered again upon the closing of the Merger. Prior to the closing of the Merger, the Company intends to coordinate with the lenders to either (a) seek to amend the definition of Change of Control permitting the Merger; or (b) to refinance or enter into new debt agreements that would permit the Merger. The Change of Control provisions in the PNM debt agreements are not triggered by the close of the Merger.
To ensure sufficient liquidity pending the Lender Consents, on May 18, 2025, TXNM entered into a $910.0 million 364-day revolving credit facility (the “TXNM Merger Backstop Revolving Facility") between TXNM, the lenders party thereto, and Wells Fargo Bank, National Association, as administrative agent. The TXNM Merger Backstop Revolving Facility was available to provide liquidity in the event the Company was unable to obtain the Lender Consents. On May 19, 2025, TXNM borrowed approximately $4.0 million under the TXNM Merger Backstop Revolving Facility and subsequently repaid the entire balance by May 21, 2025. The TXNM Merger Backstop Revolving Facility expired according to its terms as TXNM did not make any additional borrowings thereunder by the commitment termination date of May 23, 2025, and the Company was able to obtain the Lender Consents.

On May 18, 2025, concurrent with the execution of the TXNM Merger Backstop Revolving Facility, TNMP entered into a $1,505.0 million 364-day delayed-draw term loan (the “TNMP Merger Backstop Term Loan”) between TNMP, the lenders party thereto, and Wells Fargo Bank, National Association, as administrative agent. The TNMP Merger Backstop Term Loan was available to provide liquidity to repurchase TNMP’s FMBs that were tendered for prepayment pursuant to the Offer. Borrowings under the TNMP Merger Backstop Term Loan are short-term in nature, and bear interest at a variable rate, which was 5.42% at June 30, 2025. On July 21, 2025 TNMP issued the TNMP July 2025 FMBs and used the proceeds to repay the outstanding principal balance under the TNMP Merger Backstop Term Loan on July 22, 2025, terminating that agreement. As TNMP demonstrated the intent and ability to refinance this short-term obligation prior to the issuance of this Form 10-Q, the obligation that existed as of June 30, 2025 has been presented as Long-term Debt on the Condensed Consolidated Balance Sheets.

On May 18, 2025, concurrent with the execution of the Merger Agreement, TXNM entered into an agreement (the “May 2025 Stock Purchase Agreement”) whereby TXNM sold, in a private placement transaction, 8,000,000 shares of TXNM common stock for a purchase price of $50.00 per share (aggregating $400.0 million). The consummation of the May 2025 Stock Purchase Agreement occurred on June 2, 2025. TXNM used the proceeds to make a cash equity contribution of $160.0 million to TNMP, to repay borrowings under the TXNM Revolving Credit Facility, and for general corporate purposes.

On May 16, 2025, TXNM paid the remaining balance due under its TXNM 2021 Delayed Draw Term Loan in accordance with its terms.

On April 23, 2025, PNM entered into an agreement (the “PNM April 2025 Note Purchase Agreement”) with institutional investors for the sale and issuance of $300.0 million aggregate principal amount of two series of SUNs (the “PNM April 2025 SUNs”) offered in private placement transactions. The PNM April 2025 SUNs were issued on April 23, 2025. PNM issued $125.0 million of the PNM April 2025 SUNs at 5.75%, due June 1, 2032, and another $175.0 million at 6.13%, due June 1, 2037. PNM used proceeds from the PNM April 2025 SUNs for the repayment of existing indebtedness, funding of capital expenditures, and general corporate purposes. The PNM April 2025 Note Purchase Agreement includes the customary covenants discussed above. In the event of a change of control, PNM will be required to offer to prepay the PNM April 2025 SUNs at par. Although there are customary change of control provisions in the PNM debt agreements, the change of control provisions in the agreements, including the PNM April 2025 Note Purchase Agreement, are not triggered by the closing of the Merger. PNM has the right to redeem any or all of the PNM April 2025 SUNs prior to their maturities, subject to payment of a customary make-whole premium.

On February 14, 2025, TNMP entered into an agreement (the “TNMP February 2025 Bond Purchase Agreement”) with institutional investors for the sale and issuance of $140.0 million aggregate principal amount of first mortgage bonds (the “TNMP February 2025 Bonds”) offered in private placement transactions. TNMP issued all $140.0 million of the TNMP February 2025 Bonds on February 14, 2025 at a 5.19% interest rate, due April 1, 2031. The proceeds were used to repay borrowings under the TNMP Revolving Credit Facility, for funding of capital expenditures, and for other corporate purposes. The TNMP February 2025 Bonds are subject to continuing compliance with the representations, warranties, and covenants set forth in the supplemental indentures governing the TNMP February 2025 Bonds. The terms of the supplemental indentures governing the TNMP February 2025 Bonds include the customary covenants discussed above. In the event of a change of control, TNMP will be required to offer to prepay the TNMP February 2025 Bonds at par. The definition of change of control in the supplemental indentures governing the TNMP February 2025 Bonds were triggered by the execution of the Merger Agreement and the TNMP February 2025 Bonds were included in the Offer, with $40.0 million validly tendered by the bondholders and accepted for purchase by TNMP. The change of control for the remaining $100.0 million of TNMP February 2025 Bonds will again be triggered by the close of the Merger. TNMP has the right to redeem any or all of the TNMP February 2025 Bonds prior to their maturity, subject to payment of a customary make-whole premium.
On January 21, 2025, PNM entered into a $195.0 million term loan agreement (the “PNM 2025 Term Loan”), among PNM, the lenders party thereto and Canadian Imperial Bank of Commerce, New York Branch, as administrative agent. PNM used the proceeds of the PNM 2025 Term Loan to repay borrowings under the PNM Revolving Credit Facility and the PNM New Mexico Credit Facility, and for general corporate purposes. The PNM 2025 Term Loan bears interest at a variable rate, which was 5.32% at June 30, 2025, and must be repaid on or before July 21, 2026.

On May 6, 2024, TXNM entered into a distribution agreement with BofA Securities, Inc., Citigroup Global Markets, Inc., MUFG Securities Americas Inc., RBC Capital Markets, LLC, Scotia Capital (USA) Inc., and Wells Fargo Securities, LLC, as sales agents and Bank of America, N.A., Citibank, N.A., MUFG Securities EMEA plc, Royal Bank of Canada, The Bank of Nova Scotia, and Wells Fargo Bank, N.A., as forward purchasers, pursuant to which the Company may sell, from time to time, up to an aggregate sales amount of $100.0 million of its common stock, no par value, through the sales agents (the “TXNM 2024 ATM Program”). On August 5, 2024, subsequent to approval by shareholders to increase TXNM’s authorized shares, the Company amended the distribution agreement increasing the aggregate sales amount from $100.0 million to $300.0 million of its common stock, no par value, that may be sold under the TXNM 2024 ATM Program. The Company did not initially receive any proceeds from the execution of the distribution agreement.

On May 10, 2024, PNM entered into a $200.0 million term loan agreement (the “PNM 2024 Term Loan”), among PNM, the lenders party thereto and U.S. Bank National Association, as administrative agent. PNM used the proceeds of the PNM 2024 Term Loan to repay borrowings under the PNM Revolving Credit Facility, the PNM New Mexico Credit Facility, and for general corporate purposes. The PNM 2024 Term Loan bears interest at a variable rate, which was 5.32% at June 30, 2025, and must be repaid on or before November 10, 2025.

On June 10, 2024, TXNM issued $500.0 million aggregate principal amount of junior subordinated convertible notes due 2054 (the “Convertible Notes”) in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The Convertible Notes are unsecured obligations of the Company and rank junior and subordinate in right of payment to the prior payment in full of the Company’s existing and future senior indebtedness. The Convertible Notes bear interest at a rate of 5.75% per year, payable semi-annually in arrears on June 1 and December 1, and mature on June 1, 2054, unless earlier converted, redeemed, or repurchased in accordance with their terms. On June 21, 2024, TXNM issued an additional $50.0 million aggregate principal amount of the Convertible Notes, pursuant to an overallotment option granted by TXNM to the initial purchasers of the $500.0 million Convertible Notes.
