GRUPO TMM REPORTS FOURTH QUARTER AND FULL YEAR 2025 FINANCIAL RESULTS

(In Mexican Pesos)

GRUPO TMM REPORTS IMPROVED OPERATING PERFORMANCE AND PROFITABILITY IN 2025

Preliminary full-year 2025 Results Include:

Consolidated revenues of Ps 1,909.0 million

EBITDA of Ps 437.0 million

Net income of Ps 341.3 million

Significant improvement in operating income

Mexico City, February 27, 2026 – Grupo TMM, S.A.B. (BMV: TMM A and OTC: GTMAY) (the “Company” or “TMM”), a Mexican maritime transportation, logistics and maritime infrastructure services company, announced its preliminary financial results for the fourth quarter and full year 2025

“Fiscal year 2025 marked the beginning of a period of more consistent performance for Grupo TMM, supported by the maturity of our operations and disciplined execution.

In 2026, we will continue strengthening our value proposition through digital tools, enhanced operating efficiency and sustainable practices aligned with our operations,” said Vanessa Serrano, Chief Executive Officer of TMM.

Operational performance

During 2025, Grupo TMM reported higher asset utilization, improved contract visibility and a more efficient operating structure, resulting in consolidated revenue of Ps 1,909.0 million and operating income of Ps. 329.7 million.

Although full-year net income included favorable foreign exchange effects, the year-over-year improvement was primarily driven by operating performance.

Segment performance

•

Maritime – maintained high utilization levels and remained the main contributor to earnings, supported by improved contract visibility and consistent margin generation associated with fleet utilization.

•

Maritime Infrastructure – the fourth quarter included closing adjustments that temporarily impacted profitability; however, the segment generated a higher contribution supported by expanded operating capabilities and specialized services.

•

Land Logistics – maintained stable performance driven by operating efficiencies and higher volumes.

Overall, these factors reflect the maturation of the Company’s operating model.

Comparability of figures

As of October 1, 2025, the Company ceased consolidating the storage business; therefore, fourth-quarter and full-year figures partially include this segment. This effect solely reflects a change in consolidation scope and does not affect the performance of the Company’s core businesses.

Outlook

For 2026, the Company will remain focused on the optimization of its strategic assets, maintaining financial discipline, and pursuing selective expansion into markets and segments aligned with its operating capabilities.

Headquartered in Mexico City, Grupo TMM is a Mexican company that provides comprehensive solutions in maritime transportation, maritime infrastructure, and ports & terminals logistics operations, through its subsidiaries and affiliated offices.
