Slide 2 — Disclosures

Disclosures Note: unless otherwise stated, all values included are in United States dollars. This Presentation is provided to you on the condition that you agree that you will not reproduce, forward or distribute it in whole or in part to any third party without the prior written consent of Telesat Corporation (together, with its direct and indirect subsidiaries, “Telesat” or the “Company”). To the maximum extent permitted by law, none of Telesat, its affiliates, directors, officers, employees, agents, advisors or representatives, nor any other person, accepts any liability, including, without limitation, any liability arising out of fault or negligence for any loss arising from the use of the information contained in this Presentation. This Presentation has been prepared solely for informational purposes, and this Presentation is not, and should not be assumed to be, complete. This presentation is a summary only of certain information in respect of the Company and any recipient hereof should conduct its own independent investigation and analysis of the Company, including legal, accounting and other relevant professional advice. Acceptance of this presentation further constitutes your acknowledgment and agreement that none of Telesat or its affiliates, directors, officers, employees, agents, advisors or representatives (i) makes any representation or warranty, express or implied, as to the accuracy or completeness of the information contained herein or any other information (whether communicated in written or oral form) transmitted or made available to recipients of this Presentation or (ii) shall have any liability to the recipient or its representatives relating to or arising from the information contained herein or any omissions from such information, or any other written or oral communication transmitted to any interested party in the course of its evaluation of Telesat. This Presentation does not constitute an offer to sell, or a solicitation of an offer to purchase, any securities from any of the entities discussed herein. Third Party Information Although all information and opinions expressed in this Presentation, including market data and other statistical information (including estimates and projections relating to the addressable market), were obtained from sources believed to be reliable and are included in good faith, Telesat has not independently verified the information and makes no representation or warranty, express or implied, as to its accuracy or completeness. Some data is also based on the good faith estimates of Telesat, which are derived from its review of internal sources as well as the independent sources described above. This Presentation contains preliminary information only, is subject to change at any time and, is not, and should not be assumed to be, complete. While Telesat is not aware of any misstatements regarding the industry and market data presented in this Presentation, such data involves risks and uncertainties and are subject to change based on various factors, including those factors discussed under “Forward-Looking Information”. Non-GAAP Financial Measures Unless otherwise indicated, financial information in this presentation has been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board. IFRS differs in some respects from United States generally accepted accounting principles (“U.S. GAAP”), and thus our financial statements may not be comparable to the financial statements of United States companies prepared in accordance with U.S. GAAP. This Presentation includes certain financial measures not presented in accordance with IFRS or U.S. GAAP, including but not limited to, Adjusted EBITDA, Adjusted EBITDA margin, and Free Cash Flow. Adjusted EBITDA and Adjusted EBITDA are non-GAAP financial measures as defined in National Instrument 52-112 Non- GAAP and Other Financial Measures Disclosure (“NI 52-112”). Adjusted EBITDA margin is a non-GAAP ratio as defined in NI 52-112 and is the ratio of Adjusted EBITDA to revenue. These measures are not recognized measures under IFRS, do not have standardized meanings prescribed by IFRS and are therefore unlikely to be comparable to similar measures presented by other companies. Rather, these measures are provided as additional information to complement those IFRS measures by providing further understanding of our results of operations from management’s perspective. These measures may exclude items that are significant in understanding and assessing Telesat’s financial results, and therefore should not be considered as alternatives to net income or any other measures derived in accordance with IFRS or U.S. GAAP. Additionally, these measures should not be considered in insolation or as a substitute for analysis of our financial information reported under IFRS. Reconciliations of these non-GAAP financial measures to IFRS are included in the Appendix hereto. Additional information and further reconciliations with respect to the non-IFRS measures included in this Presentation, including among other things, disclosure of their composition, how each non-IFRS measure provides useful information to investors and the additional purposes, if any, for which management uses each non-IFRS measure and reconciliations of non-IFRS measures to the closest IFRS measure can be found in the section entitled “Non-IFRS Measures” in our Management’s Discussion and Analysis (the “MD&A”) dated March 18, 2026 as at and for the year ended December 31, 2025, which information is incorporated by reference in this Presentation. The MD&A is available under our corporate profile on SEDAR+ at www.sedarplus.ca and EDGAR at www.sec.gov. 2

Slide 3 — Disclosures

Disclosures 3 Forward-looking Statements This presentation contains statements that are not based on historical fact, including financial outlook for 2026 and future years, estimated timing of the commencement of global commercial service on Telesat Lightspeed, the growth opportunities of Telesat Lightspeed and the increasing demand from defence and other vertical segments, and are “forward-looking statements’’ and “future-orientated financial performance” within the meaning of the Private Securities Litigation Reform Act of 1995 and Canadian securities laws. When used herein, statements which are not historical in nature, or which contain the words “will,” “expect,” “continue,” or similar expressions, are forward-looking statements. Actual results may differ materially from the expectations expressed or implied in the forward- looking statements and future-orientated financial information as a result of known and unknown risks and uncertainties. Future-orientated financial information contained in this news release about prospective financial performance, financial position, or cash flows are expected to give the reader a better understanding of the potential future performance of Telesat. Readers are cautioned that any such future-orientated financial information and financial outlook contained herein should not be used for purposes other than those disclosed herein. All statements made in this news release are made only as of the date set forth at the beginning of this release. Telesat undertakes no obligation to update the information made in this news release in the event facts or circumstances subsequently change after the date of this release. These forward-looking statements and future-orientated financial information are not guarantees of future performance, are based on Telesat’s current expectations, and are subject to a number of risks, uncertainties, assumptions, and other factors, some of which are beyond Telesat control, are difficult to predict, and could cause actual results to differ materially from those expressed or forecasted in the forward-looking statements. Known risks and uncertainties include but are not limited to: risks associated with financial factors, including swings in the global financial markets, access to capital to construct our LEO satellite constellation, the ability to refinance Telesat GEO Inc.’s debt, the outcome of litigation related to Telesat GEO Inc.’s debt and the 62% equity distribution, volatility of securities values in an industry sector where values may be influenced by economic and other factors beyond Telesat’s control, inflation, rising or prolonged elevated interest rates, fluctuations in foreign exchange rates, and tariffs; risks associated with operating satellites and providing satellite services, including satellite construction or launch delays, launch failures, in-orbit failures, impaired satellite performance or dependence on large customers; the ability to deploy successfully an advanced global LEO satellite constellation and the timing of any such deployment; Telesat’s ability to meet the conditions for advance of the loans under the funding agreements for the constellation; technological hurdles, including Telesat’s and Telesat’s contractors’ development and deployment of the new technologies required to complete the constellation in time to meet Telesat’s schedule, or at all, the availability of services and components from Telesat’s and Telesat’s contractors’ supply chains; competition, including with other LEO systems, deployed and yet to be deployed; risks associated with domestic and foreign government regulation, including government restrictions and regulations, access to sufficient orbital spectrum to be able to deliver services effectively and access to sufficient geographic markets in which to sell those services; Telesat’s ability to develop significant commercial and operational capabilities; and the ability to expand Telesat’s existing satellite utilization. The foregoing list of important factors is not exhaustive. Investors should review the other risk factors discussed in Telesat’s annual report on Form 20-F for the year ended December 31, 2025, that was filed on March 17, 2026, and the Form 6-K that was filed on May 5, 2026, with the United States Securities and Exchange Commission (SEC) and the Canadian securities regulatory authorities at the System for Electronic Document Analysis and Retrieval + (SEDAR+), and may be accessed on the SEC’s website at www.sec.gov and SEDAR’s website at www.sedarplus.ca. The forward-looking statements also contain future-oriented financial information and information which could be considered to be in the nature of a financial outlook (together with the future-oriented financial information, “FOFI”), which involves statements about Telesat’s prospective financial performance, financial position or cash flows, including, but not limited to, market growth, revenue projections, and capital expenditures. All FOFI contained in this Presentation is subject to the same assumptions, risks, limitations and qualifications as set forth above. All FOFI included in this Presentation is provided for the purpose of helping readers understand Telesat’s current expectations and plans for the future. Readers are cautioned that reliance on FOFI may not be appropriate for other purposes or in other circumstances. The actual results of Telesat’s operations will likely vary from the amounts set forth in any financial outlook and such variances may be material. Historical statements contained in this Presentation regarding past trends or activities should not be taken as a representation that such trends or activities will continue in the future. No statement in this document is intended to be nor may be construed as a profit forecast. Trademarks The use or display of third parties’ trademarks, service marks, trade names or products in this presentation is not intended to, and does not imply, a relationship with Telesat, or an endorsement or sponsorship by or of Telesat. 3
