Next Steps / Actionable Advice
  • The next observable evidence is MDA's confirmed completion date for the two 'pathfinder' satellites, or Telesat announcing a revised launch cadence with SpaceX.

Telesat announced a three-month delay in launching its first Lightspeed constellation craft. CEO Dan Goldberg stated that the slip is due to delays in the construction of the initial 'pathfinder' satellites, which are being developed by MDA Space. This manufacturing constraint creates a knock-on effect on Telesat’s reserved launch schedule with SpaceX.

The operational timeline has shifted; Telesat reportedly aims to launch the two pathfinders using a SpaceX rocket around June 2028. The initial fleet requires 156 satellites, and Telesat currently has 14 launches booked with SpaceX, needing one more to complete that initial deployment phase. Following the pathfinder launch, Telesat expects SpaceX to handle deployments of 15 Lightspeed satellites every three weeks in mid-to-late 2028.

Investors should re-evaluate capital deployment timelines given the shift toward a June 2028 pathfinder launch date and the current performance headwinds in the GEO segment.

While addressing the LEO delay, Goldberg also provided a financial update on the company’s existing Geostationary Orbit (GEO) business. For the quarter ended September 30th, Telesat reported GEO revenue of $79 million, representing a 21 percent decrease compared to the prior year. The decline was attributed primarily to non-renewal of a broadcast contract and capacity reductions for several customers.

Despite the segment downturn, Telesat confirmed it is reiterating its 2026 GEO revenue guidance while maintaining a disciplined approach to cost management in that business. Separately, the company noted it had invested C$3.1 billion (€1.9bn) into Lightspeed as of September 30th.
