Telesat (TSAT) Q3 2025 earnings review
Legacy GEO Collapse Accelerates as LEO Bet Consumes Cash
Telesat is in a brutal transition phase. Revenue is rapidly decelerating, dropping 27% YoY in Q3 to $101 million as legacy GEO contracts reset at lower rates or expire entirely. The bottom line is reversing—swinging from a $68M profit a year ago to a $121M net loss. While management emphasizes a fully-funded $1.1B LEO backlog for its future Lightspeed constellation, the present reality is dire: staggering cash burn, leverage soaring to 8.7x, and implied Q4 guidance that points to near-zero EBITDA. Telesat is racing against its own balance sheet before the new network launches in late 2026.
🐂 Bull Case
The initial 156-satellite constellation is fully backed by government loans, internal equity, and vendor financing, removing near-term capital raise risk for the build-out.
Rising NATO defense budgets and Arctic sovereignty initiatives provide a massive structural demand catalyst for Lightspeed's dual-use, highly secure optical network.
🐻 Bear Case
The legacy business is collapsing faster than expected. Q3 margins compressed to 46.3% from 69.5% a year ago, choking off the cash flow needed to bridge the gap to 2027.
Total leverage sits at 8.67x. Negotiations to restructure the legacy GEO debt have barely begun, and management admits it is 'too early to say' how they will be resolved.
⚖️ Verdict: 🔴
Bearish. The LEO thesis is promising, but the math is terrifying. The legacy business is evaporating so quickly that implied Q4 guidance suggests a total collapse in EBITDA. The execution window is incredibly tight.
Key Themes
Defense and Government Macros Tailwinds
Telesat is heavily indexing its future on public sector demand. Management highlighted accelerating NATO spending commitments from Canada and allied nations as a primary catalyst. Beyond the foundational $60M/year Canadian rural broadband contract, the 'dual-use' nature of Lightspeed is perfectly positioned to capture sovereign defense contracts, particularly for Arctic communications.
Strategic LEO Spin-off Protects Future Value
In a major structural shift, Telesat distributed 62% of the equity in the Lightspeed project to a separate, non-guarantor subsidiary in September. This legal maneuvering legally isolates the future growth engine from the heavily indebted legacy GEO business, preserving future financing flexibility.
Open Ecosystem and Tech Innovation
Unlike closed systems, Telesat is building an open-architecture network. The constellation is SDA-compliant (Space Development Agency), allowing interoperability with government networks. Partnerships with Farcast and Intellian for flat-panel aeronautical antennas are critical technology enablers to capture the high-margin aviation market.
The Legacy Death Spiral
The decline in the core GEO business is stable but severe. Revenue fell 27% YoY due to the Nimiq 5 DTH contract repricing at lower rates and the end-of-life for the Anik F3 satellite. Compounding this, Starlink is aggressively cannibalizing Telesat's enterprise and maritime segments. With no new GEO satellites ordered in 9 years, this segment is in terminal runoff.
Stagnant LEO Backlog Contradicts 'Strong Demand' Narrative
Management repeatedly touted 'strong commercial interest' and a 'robust pipeline' for Lightspeed. However, the data contradicts this optimism: the LEO backlog was reported at $1.1B in Q1 2025, 'over $1B' in Q2, and remains exactly $1.1B in Q3. Since the Viasat deal in April, commercial momentum has entirely stalled, and the backlog is stable rather than accelerating.
GEO Debt Restructuring Gridlock
With 8.67x leverage, refinancing the restricted group debt (maturing Dec 2026) is the company's biggest existential threat. Despite calling it a 'key priority' since Q4 2024, management admitted in the Q3 call that negotiations have just begun and it is 'too early to say' what the path forward is. This uncertainty is a massive overhang.
Other KPIs
Reversing significantly. Operating cash flow of $96.9M was completely overwhelmed by $544.7M in capital expenditures. Telesat is fully reliant on drawing down its $2.54B in government loan facilities (CAD $540M drawn to date) to fund the Lightspeed build.
Accelerating. Up 26% YoY from $45.9M. This was driven by a surge in LEO headcount and elevated legal/professional fees related to the complex Lightspeed equity spin-out and debt restructuring preparations.
A rare bright spot. Since 2022, Telesat has opportunistically repurchased $857M in debt principal for just $450M (average price $0.53). This aggressive liability management has reduced overall debt by ~36% and generated vital interest expense savings.
Guidance
Decelerating. Maintained guidance implies Q4 revenue of approximately $91.1M (at the midpoint). This represents a sequential drop from Q3's $101.1M and a roughly 29% YoY collapse compared to Q4 2024 ($128M).
Decelerating violently. With 9M EBITDA already at $172.9M, the midpoint of full-year guidance ($180M) implies a shocking Q4 EBITDA of just ~$7.1M. Compared to Q4 2024's $73.4M, this indicates that the loss of high-margin GEO revenue is triggering severe negative operating leverage.
Accelerating. With 9M CapEx at $544M, Telesat expects to spend an implied $355M to $555M in Q4 alone. The cash burn trajectory is steepening dramatically as satellite manufacturing with MDA ramps up for the late 2026 launch.
Key Questions
The Q4 EBITDA Cliff
Your FY25 Adjusted EBITDA guidance midpoint implies roughly $7 million in Q4, down from $47 million in Q3 and $73 million last year. Is there a one-time expense embedded in this Q4 forecast, or does this represent the new structural margin run-rate for the legacy business?
Stalled LEO Commercial Momentum
Since the Viasat announcement in Q1, the Lightspeed backlog has remained stagnant at $1.1B. If the pipeline is as robust as stated and demand is accelerating, why haven't we seen any conversion into firm take-or-pay contracts over the last six months?
Leverage and LEO Spin-off Mechanics
You recently spun out 62% of the LEO equity to a non-guarantor subsidiary. How has this structural move impacted the willingness of your GEO debt holders to negotiate, and does it increase the likelihood of a contentious restructuring process?
