ALBUQUERQUE, N.M., May 19, 2025 /PRNewswire/ -- TXNM Energy (NYSE: TXNM) today announced an agreement under which Blackstone Infrastructure will acquire TXNM Energy for $61.25 per share in cash upon closing, reflecting a total enterprise value of $11.5 billion, including net debt (excluding securitization debt) and preferred stock.

TXNM Energy, through its subsidiaries PNM and TNMP, is focused on meeting the critical electricity infrastructure needs of its customers. PNM is supporting the evolution of its generation portfolio to meet New Mexico's clean energy goals and is identifying opportunities to achieve the energy transition in a cost-effective manner for customers. TNMP has consistently increased its annual capital investments to meet sustained nation-leading growth levels in its Texas service territory. This transaction provides significant long-term capital to support these goals.

"Our successes at TXNM Energy have stemmed from a deliberate approach to investing in PNM and TNMP in a manner aligned with the priorities of our customers and communities. We've integrated new resources to supply over two-thirds of PNM electricity needs with carbon-free energy and supported double-digit demand growth at TNMP," said Pat Collawn, Chair and CEO of TXNM Energy. "We are excited to form this long-term partnership with Blackstone Infrastructure to build upon these successes. We will continue to collaborate with customers, communities, legislators and regulators to achieve our shared goals for a reliable, resilient grid to support economic prosperity and clean energy."

Blackstone Infrastructure, with its $60 billion of assets under management, is focused on investing behind North American infrastructure platforms and leveraging its scale and expertise to support the growth of its portfolio companies. Blackstone Infrastructure has perpetual capital with no obligation to sell its investments, and is focused on long-term, multi-decade partnerships with the companies and communities in which it invests. In 2023 and 2024 alone, Blackstone Infrastructure committed over $5 billion of equity to its portfolio companies. It is an experienced North American utility investor and recognizes the value of long-term investments in critical infrastructure that help communities thrive.

"We are excited to partner with Pat, Don and their fantastic team to accelerate growth at TXNM, and across New Mexico and Texas." said Sean Klimczak, Global Head of Blackstone Infrastructure. "We are long-term investors who back industry-leading companies using our perpetual capital to support economic development. We are focused on being great long-term partners to the communities in which we invest, and we look forward to having the opportunity to engage in meaningful dialogue about how we can create win-win, growth-oriented investments across both states."

Blackstone Infrastructure is funding the purchase price entirely with equity and does not anticipate increasing TXNM Energy leverage levels to fund the purchase of the company.

Valuing Customers, Employees and Communities
Blackstone Infrastructure intends to support TXNM Energy's long-standing commitments to its customers, employees and communities, including:

• Keeping Customers First: PNM and TNMP will continue to prioritize cost-effective solutions to provide safe, reliable power to meet customer needs across New Mexico and Texas.
