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 or enter into term loan 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 contain 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. Financing Activities TXNM At December 31, 2022, TXNM had $1.0 billion outstanding under the 2021 Delayed-Draw Term Loan, among TXNM, the lenders party thereto, and Wells Fargo Bank, N.A., as administrative agent. As discussed below on June 30, 2023, $500.0 million under the TXNM 2021 Delayed Draw Term Loan was prepaid, without penalty, with proceeds from the TXNM 2023 Term Loan. As discussed below, on June 21, 2024, proceeds from the Convertible Notes were used to prepay, without penalty, $449.0 million under the TXNM 2021 Delayed Draw Term Loan. Draws on the TXNM 2021 Delayed-Draw Term Loan bear interest at a variable rate, which was 5.41% at December 31, 2024. On March 2, 2022, 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 March 2025. On November 10, 2022, TXNM entered into a distribution agreement with BofA Securities, Inc., MUFG Securities Americas Inc. and Wells Fargo Securities, LLC, as sales agents, and Bank of America, N.A., MUFG Securities EMEA plc 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 price of $200.0 million of its common stock, no par value, through the sales agents (the “TXNM 2022 ATM Program”). Sales of the shares made pursuant to the distribution agreement may be made in “at the market offerings” as defined in Rule 415 of the Securities Act. TXNM did not initially receive any proceeds upon the execution of this agreement. Throughout 2023, TXNM entered into forward sale agreements, for the sale of shares of TXNM common stock. On December 15, 2023, TXNM physically settled the forward purchases under the TXNM 2022 ATM Program and used the proceeds to repay borrowings under the TXNM Revolving Credit Facility and for other corporate purposes. Cash proceeds shown below were reduced by $1.0 million in issuance costs resulting in net cash proceeds of $198.2 million.

On June 30, 2023, TXNM entered into a $500.0 million term loan agreement (the “TXNM 2023 Term Loan”) among TXNM, the lenders party thereto, and Wells Fargo Bank, N.A., as administrative agent. The proceeds were used to prepay an equal amount of the TXNM 2021 Delayed Draw Term Loan, without penalty. As discussed below, on June 21, 2024, proceeds from the Convertible Notes were used to prepay, without penalty, $90.0 million under the TXNM 2023 Term Loan. The TXNM 2023 Term Loan matures on June 30, 2026 and bears interest at a variable rate, which was 5.81% at December 31, 2024. 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. Sales of the shares made pursuant to the distribution agreement may be made in “at the market offerings” as defined in Rule 415 of the Securities Act. TXNM did not initially receive any proceeds upon the execution of this agreement. TXNM entered into forward sales agreements with forward purchasers relating to the sale of 262,025 shares of common stock, at an initial forward sale price of $37.77 per share in the second quarter; 2,196,926 shares of common stock at a weighted average initial forward sale price of $40.58 per share in the third quarter; and 1,104,641 shares of common stock at a weighted average initial forward sale price of $44.83 per share in the fourth quarter. All initial forward prices under the agreements are subject to adjustments based on a net interest rate factor and by future dividends paid on TXNM common stock. On December 30, 2024, TXNM physically settled forward purchases under the TXNM 2024 ATM Program for 2,458,951 shares and used the proceeds to repay borrowings under the TXNM Revolving Credit Facility.

As of December 31, 2024, 1,104,641 shares under forward sales agreements under the 2024 TXNM ATM Program remained unsettled. 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. Proceeds from the Convertible Notes were used to prepay $449.0 million of borrowings under the TXNM 2021 Delayed Draw Term Loan and $90.0 million of borrowings under the TXNM 2023 Term Loan, without penalty, and for other corporate purposes. TXNM may not redeem the Convertible Notes prior to June 6, 2029, except upon the occurrence of certain tax events, rating agency events or treasury stock events (each, a “special event”). TXNM may redeem for cash all, but not less than all, of the Convertibles Notes upon the occurrence of a special event at any time, at its option, at a redemption price equal to 100% of the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. In addition, TXNM may redeem for cash all or part (subject to certain limitations on partial redemptions) of the Convertible Notes, at its option, on or after June 6, 2029, at a redemption price equal to 100% of the principal amount of the convertible notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date, if the last reported sale price of TXNM’s common stock has been at least 130% of the conversion price of the convertible notes then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which TXNM provides notice of redemption. In each case, TXNM will not, and will not be permitted to, issue a notice of redemption, or specify a redemption date, during any interest deferral period. Prior to the close of business on the business day immediately preceding December 1, 2053, the Convertible Notes will be convertible at the option of the holders only under certain conditions. On or after December 1, 2053 until the close of business on the second business day immediately preceding the maturity date, holders may convert all or any portion of their Convertible Notes at their option, at any time, at the conversion rate then in effect, irrespective of these conditions. Upon conversion of the Convertible Notes, TXNM will pay cash, or deliver an equal aggregate principal amount of a newly issued series of its nonconvertible junior subordinated notes with the same terms as the Convertible Notes (other than the conversion features and certain features in relation to redemption rights), in either case, up to the aggregate principal amount of the Convertible Notes being converted, and deliver shares of TXNM’s common stock in respect of the remainder, if any, of TXNM’s conversion obligation in excess of the aggregate principal amount of the Convertible Notes being converted. The conversion rate for the Convertible Notes will initially be 22.4911 shares of TXNM’s common stock per $1,000 principal amount of the Convertible Notes, equivalent to an initial conversion price of $44.46 per share of common stock. The initial conversion price of the Convertible Notes represents a conversion premium of 17.5% above the last reported sale price of TXNM’s common stock on June 4, 2024. The conversion rate and the corresponding conversion price will be subject to adjustment by certain events such as increased dividends but will not adjust for any accrued or unpaid interest. In addition, following certain corporate events that occur prior to the maturity date of the Convertible Notes or if TXNM delivers a notice of a special event redemption, TXNM will, in certain circumstances, increase the conversion rate for a holder that elects to convert its Convertible Notes in connection with such a corporate event or such notice of special event redemption, as the case may be. TXNM issued the Convertible Notes pursuant to an indenture (the “Convertible Notes Indenture”) dated as of June 10, 2024 between TXNM and Computershare Trust Company, N.A., as trustee. The Convertible Notes are subject to continuing compliance with the representations, warranties, and covenants set forth in the Convertible Notes Indenture, which include the customary covenants discussed above. In the event of a fundamental change, as defined in the Convertible Notes Indenture, TXNM may be required to repurchase, for cash, the aggregate principal amount of Convertible Notes plus accrued interest. TXNM may not redeem the Convertible notes prior to June 6, 2029 except upon the occurrence of a special event as defined in the Convertible Notes Indenture. So long as no event of default with respect to the Convertible Notes has occurred and is continuing, TXNM may, at its option, defer interest payments on the Convertible Notes on one or more occasions for up to 20 consecutive semi-annual interest payment periods. During any deferral period, interest on the Convertible Notes will continue to accrue at the then-applicable interest rate on the Convertible Notes. In addition, during any deferral period, interest on deferred interest will accrue at the then-applicable interest rate on the Convertible Notes, compounded semi-annually, to the extent permitted by applicable law.

At December 31, 2023, the fair value of the active hedging agreements was a gain of $7.2 million that was included in Other current assets and a loss of $2.3 million that was included in Other deferred credits on the Consolidated Balance Sheets. Fair values were determined using Level 2 inputs under GAAP, including using forward SOFR curves under the mid-market convention to discount cash flows over the remaining term of the agreements. In November 2024, TXNM unwound and settled the $300.0 million of hedging agreements that were expected to mature on December 31, 2025, and on December 31, 2024, the remaining $600.0 million of hedging agreements matured. TXNM had no active hedging agreements at December 31, 2024. Borrowing Arrangements Between TXNM and its Subsidiaries TXNM has intercompany loan agreements with its subsidiaries. Individual subsidiary loan agreements vary in amount up to $150.0 million and have either reciprocal or non-reciprocal terms. Interest charged to the subsidiaries is equivalent to interest paid by TXNM on its short-term borrowings or the money-market interest rate if TXNM does not have any short-term borrowings outstanding. All balances outstanding under intercompany loan agreements are eliminated upon consolidation. See Note 1. PNM and TNMP had no borrowings from TXNM at December 31, 2024 and 2023. PNMR Development had zero and $2.3 million in short-term borrowings outstanding from TXNM at December 31, 2024 and 2023.
