2025 SOLID GROWTH. LOW RISK. REPEATABLE PERFORMANCE. This was a defining year for TC Energy-we demonstrated the strength of our strategy and our differentiated position in the fastest-growing segments of the energymarket: natural gas and power generation. In the face of complexity and change, we continued to operate our North American natural gas and power assets safely and reliably, while delivering nation-building infrastructure. As one of our valued shareholders, we thank you for your support. 26 $ 8.3B CONSECUTIVE YEARS OF DIVIDEND INCREASES 1 COMPARABLE EBITDA GROWTH YEAR OVER YEAR 2 OF PROJECTS PLACED INTO SERVICE, ~15% BELOW BUDGET 1 2025 represents an increase from TC Energy's proportionate allocation of the dividend following the Spino¦ Transaction. 2 Comparable EBITDA is a non-GAAP measure used throughout this document. This measure does not have any standardized meaning under GAAP and therefore is unlikely to be comparable to similar measures presented by other companies. The most directly comparable GAAP measure is segmented earnings (losses). Refer to the Non-GAAP measures section of the 2025 Annual MD&A (incorporated by reference) for more information about the non-GAAP measures we use and for a reconciliation of Comparable EBITDA to segmented earnings (losses).
