Rhea-AI Filing Summary

TXNM Energy, Inc. has notified holders that its 5.75% Junior Subordinated Convertible Notes due 2054 are convertible at the holders’ option from April 1, 2026 through June 30, 2026. The notes convert at a rate of 22.5382 shares of common stock per $1,000 principal, equivalent to a conversion price of about $44.37 per share.

For any conversion during this period, TXNM will deliver a new series of 5.75% non-convertible junior subordinated notes due 2054 equal to the principal amount converted, plus shares of common stock (and cash in lieu of fractions) only for any value above principal, calculated over a 60-trading-day observation period. The company warns these new non-convertible notes may be less liquid and less attractive than similar securities such as its 7.000% junior subordinated notes due 2056. The filing also reiterates the pending merger at $61.25 in cash per share with an affiliate of Blackstone Infrastructure Partners and explains that, if completed, the merger would be a “make-whole fundamental change” giving noteholders a separate, time-limited cash-only conversion right based on the merger price.

Insights

TXNM reshapes its 5.75% convertibles with a stock-plus-new-note structure.

The company is allowing conversion of its 5.75% Junior Subordinated Convertible Notes due 2054 in Q2 2026 at a fixed conversion rate of 22.5382 shares per $1,000 principal, implying a conversion price near $44.37. The trigger was the stock trading at or above 130% of the conversion price for at least 20 of 30 recent trading days.

Instead of settling principal in cash or stock, TXNM will issue equal principal of new 5.75% Non-Convertible Junior Subordinated Notes due 2054, plus shares (and fractional-share cash) only for any value above principal. The filing notes these new notes may be less liquid and less attractive than the company’s 7.000% junior subordinated notes due 2056, so the economics for converting holders depend heavily on trading levels of both the equity and the new notes.

The document also ties the notes to the previously announced cash merger at $61.25 per share with a Blackstone affiliate. If the merger closes, it becomes a “make-whole fundamental change,” giving holders a separate right to convert into cash based on the conversion rate and merger price for at least 35 trading days after the effective date. Actual impact on noteholders will depend on whether the merger closes and how the new non-convertible notes trade in the market.

"a newly issued series of its 5.75% non-convertible junior subordinated notes due 2054"
make-whole fundamental change financial
"the Merger will constitute a “make-whole fundamental change” with respect to the Convertible Notes"
A make-whole fundamental change is a contract clause that requires a company to compensate holders of certain securities (often convertible bonds or preferred shares) if a big event—like a merger, acquisition, or restructuring—removes or reduces the holders’ expected future benefits. Think of it as a shortcut payment that aims to leave investors financially ‘whole’ for lost upside or income, and it matters because it affects how much those investors get paid and how much such an event will cost the company.
conversion rate financial
"convertible at a conversion rate of 22.5382 shares of common stock per $1,000"
Conversion rate is the proportion of items, people or contracts that take a desired action out of the total possible — for example the share of website visitors who make a purchase, or the number of convertible bonds that are exchanged for shares. Investors care because it measures how effectively a business or financial instrument turns opportunity into real outcomes, like sales or share issuance, which directly affects revenue, cash flow and ownership dilution.
observation period financial
"over an observation period consisting of the 60 consecutive trading day period"
An observation period is a defined span of time during which a company, regulator, or clinical team watches and records specific outcomes or behaviors to see whether predetermined conditions are met. Investors care because results observed during this window — such as trial safety and efficacy, regulatory compliance, or achievement of performance targets — often trigger approvals, payments, or changes in a company’s prospects; think of it like a monitoring window that determines whether a project moves forward or stalls.

Item 8.01    Other Events.

TXNM Energy, Inc. (the “Company”) today notified holders of its 5.75% Junior Subordinated Convertible Notes due 2054 (the “Convertible Notes”) that the Convertible Notes are convertible, at the option of the holders (the “Conversion Option”), over a period beginning on April 1, 2026, and ending at the close of business on June 30, 2026 (the “Second Quarter 2026 Conversion Period”). The Convertible Notes are convertible at a conversion rate of 22.5382 shares of common stock per $1,000 principal amount of Convertible Notes, which is equivalent to a conversion price of approximately $44.37 per share of common stock.

Upon any conversion of the Convertible Notes during the Second Quarter 2026 Conversion Period, the Company will (1) deliver (in book-entry form through DTC) an equal aggregate principal amount of a newly issued series of its 5.75% non-convertible junior subordinated notes due 2054 (the “5.75% Non-Convertible Junior Subordinated Notes”) with the same terms as the Convertible Notes (other than the conversion features and certain features in relation to redemption rights) as provided pursuant to an Indenture, dated as of June 10, 2024, between the Company and Computershare Trust Company, N.A., as trustee (the “Trustee”), and (2) deliver shares of the Company’s common stock (together with cash, if applicable, in lieu of delivering any fractional share of the common stock) in respect of the remainder, if any, of the Company’s conversion obligation in excess of the aggregate principal amount of the Convertible Notes being converted. The amount of the Company’s conversion obligation, if any, in excess of the principal amount of any Convertible Notes being converted will be determined in accordance with the terms of the Indenture, dated as of June 10, 2024, between the Company and the Trustee, governing the Convertible Notes (the “Convertible Notes Indenture”), over an observation period consisting of the 60 consecutive trading day period beginning on, and including, the second trading day immediately succeeding the relevant conversion date. Holders electing to convert their Convertible Notes during the Second Quarter 2026 Conversion Period will not receive any cash consideration in connection with such a conversion (other than any cash paid in lieu of delivery of a fractional share of the common stock).

The Convertible Notes became convertible during the Second Quarter 2026 Conversion Period because the last reported sale price of shares of the Company’s common stock, for at least 20 trading days during the period of 30 consecutive trading days ending on, and including, the last trading day of the calendar quarter ended March 31, 2026, was greater than or equal to 130% of the conversion price in effect on each applicable trading day. Any determination regarding the convertibility of the Convertible Notes during future periods will be made in accordance with the terms of the Convertible Notes Indenture.

The Company has issued a notice to holders with respect to the Conversion Option specifying the applicable terms, conditions and procedures. The notice will be available through The Depository Trust Company, by requesting a copy from Computershare Trust Company, N.A., which is serving as the conversion agent, or on the Company’s website (www.txnmenergy.com) under the heading “Investors.”

None of the Company, its Board of Directors or its employees has made or is making any representation or recommendation to any holder as to whether to exercise or refrain from exercising the Conversion Option.

With respect to any conversion during the Second Quarter 2026 Conversion Period, although the Company will deliver shares of its common stock (together with cash, if applicable, in lieu of delivering any fractional share of common stock), in respect of the remainder, if any, of its conversion obligation in excess of the aggregate principal amount of Convertible Notes being converted, holders of the Convertible Notes will not be entitled to receive cash or shares of our common stock in respect of the Company’s conversion obligation up to the aggregate principal amount of Convertible Notes being converted. Instead of cash or shares of the Company’s common stock, the Company will deliver, in respect of its conversion obligation up to the aggregate principal amount of Convertible Notes being converted, an equal aggregate principal amount of the 5.75% Non-Convertible Junior Subordinated Notes, which will mature on June 1, 2054. Consequently, holders of the Convertible Notes that elect to convert their Convertible Notes during the Second Quarter 2026 Conversion Period will receive securities that are less liquid than the consideration a holder would receive if it held a convertible security that converted into cash or shares of common stock in respect of the conversion obligation up to the aggregate principal amount of Convertible Notes being converted.

In addition, the interest rate, interest deferral rights and other terms of the 5.75% Non-Convertible Junior Subordinated Notes may not be as favorable as the terms of similar securities issued at the time. For example, on December 10, 2025, the Company issued its 7.000% Fixed-to-Fixed Reset Rate Junior Subordinated Notes due 2056, which bear interest initially at a rate of 7.000% per annum. As a result, even if a liquid trading market exists for 5.75% Non-Convertible Junior Subordinated Notes, the 5.75% Non-Convertible Junior Subordinated Notes would be expected to trade at prices below the $1,000 aggregate principal amount of each 5.75% Non-Convertible Junior Subordinated Note. Further, there can be no assurance that a liquid



trading market will exist for the 5.75% Non-Convertible Junior Subordinated Notes, particularly if holders convert their Convertible Notes at a time when few Convertible Notes have been or are being converted.

As previously disclosed, on May 18, 2025, the Company, Troy ParentCo, LLC (the “Parent”), and Troy Merger Sub Inc. (the “Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which Merger Sub will merge with and into the Company, with the Company surviving the Merger as a direct wholly-owned subsidiary of Parent (the “Merger”). Parent and Merger Sub are affiliates of Blackstone Infrastructure Partners L.P. Pursuant to the Merger Agreement, each issued and outstanding share of the common stock of the Company (other than (i) the issued shares of the Company’s common stock that are owned by the Company, Parent, Merger Sub, or any other wholly-owned subsidiaries of Parent or the Company, in each case, not held on behalf of third parties, which will be automatically cancelled at the time the Merger is consummated and (ii) shares of the Company’s common stock outstanding immediately prior to the time the Merger is consummated and held by a holder who has not voted in favor of, or consented in writing to, the Merger who is entitled to, and who has demanded, payment for fair value of such shares in accordance with applicable New Mexico law) will, at the effective time of the Merger, be converted into the right to receive $61.25 in cash, without interest.

If consummated, the Merger will constitute a “make-whole fundamental change” with respect to the Convertible Notes, and holders will be entitled to surrender their Convertible Notes for conversion at any time from or after the effective date of the Merger until 35 trading days after the effective date of the Merger (or, if the Company gives notice after the effective date of the Merger, until 35 trading days after the date the Company gives notice). In such a case, (i) the consideration due upon conversion of each $1,000 principal amount of Convertible Notes will be solely cash in an amount equal to the conversion rate in effect on the conversion date (subject to potential increase as provided in the Convertible Notes Indenture), multiplied by the price paid per share of common stock in the Merger and (ii) and the Company will satisfy its conversion obligation by paying cash to converting holders on the second business day immediately following the conversion date.

Consummation of the Merger is subject to the satisfaction or waiver of certain customary conditions, including, without limitation, the absence of any material adverse effect on the Company, no legal prohibition on the consummation of the Merger, and the receipt of certain required regulatory approvals (including the Public Utility Commission of Texas, the New Mexico Public Regulation Commission, the Federal Energy Regulatory Commission, the Nuclear Regulatory Commission and under the Hart-Scott-Rodino Antitrust Improvements Act of 1976). There can be no assurance the Merger will be consummated or that the make-whole fundamental change conversion right described in the paragraph above will be available in the future.

FAQ

What conversion window did TXNM (TXNM) set for its 5.75% Convertible Notes?

TXNM’s 5.75% Junior Subordinated Convertible Notes due 2054 are convertible at holders’ option from April 1, 2026 through June 30, 2026. This Second Quarter 2026 Conversion Period was triggered when the stock price met a 130% conversion-price test.

What is the conversion rate and implied price for TXNM (TXNM) convertible notes?

Each $1,000 principal amount of TXNM’s 5.75% Convertible Notes converts at 22.5382 shares of common stock. This corresponds to an implied conversion price of approximately $44.37 per share, based on terms outlined in the note indenture.

What do TXNM (TXNM) noteholders receive when they convert during Q2 2026?

Converting holders receive new 5.75% Non-Convertible Junior Subordinated Notes due 2054 equal to the principal converted, plus TXNM common stock and cash in lieu of fractional shares only for any conversion value above principal, calculated over a 60-trading-day observation period.

Why does TXNM say the new 5.75% Non-Convertible Notes may be less attractive?

TXNM notes that the 5.75% Non-Convertible Junior Subordinated Notes may be less liquid and offer less favorable terms than similar securities. As an example, it cites its 7.000% Fixed-to-Fixed Reset Rate Junior Subordinated Notes due 2056, which pay a higher initial interest rate of 7.000% per annum.

What consideration will TXNM (TXNM) shareholders receive if the merger closes?

Each issued and outstanding TXNM common share, with specified exceptions, will be converted into the right to receive $61.25 in cash, without interest. Certain treasury, affiliate-held, and duly dissented shares are excluded or treated differently under the merger agreement and New Mexico law.
