(“BEMH,” “Valia Energía,” or the “Company”), a leading private energy producer in Mexico and a portfolio company of Actis, a growth markets investor in sustainable infrastructure and part of General Atlantic, a global investment leader, announces that Moody’s Ratings (“Moody’s”) has changed the rating outlook on the Company’s senior secured notes (VALIA E bond) to Stable from Negative. Both Moody’s Ratings and S&P Global Ratings (“S&P”) now assign a Stable Outlook to the Company’s senior secured notes due in 2039.
On January 9, 2026, Moody’s affirmed the Baa3 senior secured rating and revised the outlook to Stable, citing the successful resolution of operational issues at the Río Bravo III and EVM II plants during 2025. The year was operationally intensive, with four of the Company’s seven plants undergoing major maintenance. The mitigation and improvement actions resulted in enhanced overall fleet availability of 99% as of November 2025.
Previously, on September 5, 2025, S&P affirmed the ‘BBB’ senior secured rating on Valia’s notes and assigned a Stable Outlook. The Stable Outlook assigned by both credit agencies reflects improved operational stability and expectations of stronger recurring earnings generation in 2026 and going forward.
Valia Energía’s rating reflects its strong market position in Mexico’s energy sector, covering approximately 6% of electricity demand, with assets strategically located in high-demand industrial areas.
