## Exhibit 99.1

#### Exhibit 99.1

#### Telesat reports results for the quarter ended March 31, 2026
**OTTAWA, CANADA — May 5, 2026** — Telesat (Nasdaq and TSX: TSAT), one of the world's largest and most innovative satellite operators, today announced its financial results for the three month period ended March 31, 2026. All amounts are in Canadian dollars and reported under IFRS® Accounting Standards unless otherwise noted.

"I'm pleased with Telesat's performance in the first quarter of 2026, as the company made significant strides on a number of fronts," commented Dan Goldberg, Telesat's President and CEO. "Our GEO results are tracking to our expectations, and we continue to make strong progress on the development of the Telesat Lightspeed constellation. During the quarter, we held further design reviews with our satellite and launch vehicle dispenser manufacturers and progressed our work on user terminals, network and satellite operations software development, and ground station deployments. As of the end of the quarter, we've invested a total of approximately $2.7 billion in the Telesat Lightspeed program, including both expensed and capitalized costs. We continue to expect Telesat Lightspeed to commence global commercial service around the end of Q1 2028."

"On the commercial front, we executed a contract with Northwestel for Telesat Lightspeed service to support broadband connectivity in communities across Nunavut. That contract demonstrates the commercial appeal of Telesat Lightspeed for rural broadband, and interest remains robust at this time from government and defence users globally as well. Since announcing our plans to incorporate Military Ka-band (Mil-Ka) spectrum into the Telesat Lightspeed constellation, we've seen increased engagement from allied government customers, reinforcing our view that Telesat Lightspeed is well positioned to address fast-growing government demand for secure, resilient, and advanced satellite capabilities to meet mission-critical communications requirements around the world."

"In our GEO business, we continued to manage ongoing revenue pressures with a disciplined approach to cost control, allowing us to partially mitigate the impact of topline pressure on margins and generate resilient cash flow from our existing satellite fleet. Today, we are reiterating our revenue and adjusted EBITDA guidance for the year for our GEO segment."

"Finally, we remain focused and are working closely with our advisors on refinancing the Telesat GEO debt before it starts to mature later this year."

For the quarter ended March 31, 2026, Telesat reported consolidated revenue of $87 million, a decrease of 25% ($30 million) compared to the prior year (24% excluding the impact of foreign exchange), and adjusted EBITDA<sup>1</sup> of $35 million, a decrease of 48% ($32 million) from the first quarter of 2025 (47% excluding the impact of foreign exchange). Excluding the impact of higher expenses related to our debt refinancing process, adjusted EBITDA decreased 42%. Telesat net loss for the quarter was $151 million compared to a $51 million loss in the prior year. The increased net loss was primarily due to lower revenue and a non-cash goodwill impairment loss in our GEO segment.

In our GEO segment, revenue for the quarter was $86 million, a 26% decline ($30 million) from the same period in 2025 (24% excluding the impact of foreign exchange). The revenue decline was driven primarily by non-renewals of certain broadcast contracts in 2025 and, to a lesser extent, reductions in services for fixed broadband customers, partially offset by new contracts in our aviation segment. GEO segment adjusted EBITDA for the quarter was $53 million, a 37% ($34 million) decline from the comparable period in 2025 (35% excluding the impact of foreign exchange), reflecting lower revenue, partially offset by lower operating expenses. Adjusted EBITDA for Q1 included $7 million in expenses relating to our debt refinancing process. Excluding these costs, GEO segment adjusted EBITDA margin<sup>1</sup> was 72% during the quarter, compared to 77% in the same period of 2025.

In our LEO segment, we invested $171 million in the Telesat Lightspeed program in the first quarter of 2026, reflecting $19 million in operating expense and $152 million in capital expenditure.

As of March 31, 2026, backlog<sup>2</sup> for our GEO segment totaled approximately $800 million and LEO backlog<sup>2</sup> totaled approximately $1.1 billion. GEO satellite utilization was 55% at March 31, 2026.

#### Business Highlights
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In March, Telesat announced the addition of Mil-Ka spectrum to its advanced Telesat Lightspeed network, responding to strong global demand for mission-critical Mil-Ka capacity in LEO. Telesat Lightspeed was designed from inception to meet the security and resiliency requirements of defence organizations and the addition of Mil-Ka connectivity that will be interoperable with existing government systems further enhances its ability to support rapidly expanding defence and sovereignty requirements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In April, Northwestel, the largest communications provider in Canada's North, signed a multi-year contract for Telesat Lightspeed services. Northwestel plans to leverage Telesat Lightspeed to deliver low latency, sovereign broadband connectivity to communities throughout Nunavut.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In April, we changed the name of our GEO operating subsidiary from Telesat Canada to Telesat GEO Inc. The renaming does not impact our legal structure, ownership, operations, financial results, or subsidiaries.

#### 2026 Financial Outlook
(assumes an average foreign exchange rate of US$1=C$1.38)

Telesat is maintaining its guidance provided in March and continues to expect full year 2026:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• GEO revenue to be between $300 million and $320 million;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• GEO Adjusted EBITDA<sup>1</sup> to be between $210 million and $230 million, excluding non-recurring debt refinancing costs; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total spending on the Telesat Lightspeed program, including both expensed and capitalized costs, to be between $1.0 billion and $1.2 billion.

#### End Notes
____________

1 **Non**-IFRS **Accounting Standards Measures** — Adjusted EBITDA and Adjusted EBITDA margin are non-IFRS Accounting Standards measures. EBITDA is defined as "Earnings Before Interest, Taxes, Depreciation and Amortization." Adjusted EBITDA is used to measure Telesat's financial performance. Adjusted EBITDA is defined as operating income (less certain operating expenses such as share-based compensation expenses and unusual and non-recurring items, including restructuring related expenses) before interest expense, taxes, depreciation and amortization. Adjusted EBITDA margin is used to measure Telesat's operating performance. Adjusted EBITDA margin is defined as the ratio of Adjusted EBITDA to revenue.

Adjusted EBITDA and Adjusted EBITDA margin are not standardized financial measures under IFRS Accounting Standards and might not be comparable to similar financial measures disclosed by other issuers. Adjusted EBITDA allows investors and Telesat to compare Telesat's operating results with that of competitors exclusive of depreciation and amortization, interest and investment income, interest expense, taxes and certain other expenses. Financial results of competitors in the satellite services industry have significant variations that can result from timing of capital expenditures, the amount of intangible assets recorded, the differences in assets' lives, the timing and amount of investments, the effects of other income (expense), and unusual and non-recurring items. The use of Adjusted EBITDA assists investors and Telesat to compare operating results exclusive of these items. Competitors in the satellite services industry have significantly different capital structures. Telesat believes that the use of Adjusted EBITDA improves comparability of performance by excluding interest expense.

Telesat believes that the use of Adjusted EBITDA and the Adjusted EBITDA margin along with IFRS Accounting Standards measures enhances the understanding of our operating results and is useful to investors and us in comparing performance with competitors, estimating enterprise value and making investment decisions. Adjusted EBITDA and Adjusted EBITDA margin as used here may not be the same as similarly titled measures reported by competitors. Adjusted EBITDA and Adjusted EBITDA margin should be used in conjunction with IFRS Accounting Standards measures and are not presented as a substitute for cash flows from operations as a measure of our liquidity or as a substitute for net income (loss) as an indicator of our operating performance.

2 Telesat's backlog represents future cash inflows from capacity allocation or service delivery contracts. As of March 31, 2026, GEO backlog was $0.8 billion and represents our expected future revenue from existing GEO service contracts (without discounting for present value) including any deferred revenue that we will recognize in the future in respect of cash already received. As of March 31, 2026, the expected cash inflow from Telesat Lightspeed capacity allocation and service contracts (without discounting for present value) was $1.1 billion.

3 Includes severance payments and special compensation and benefits for executives and employees.
