Rhea-AI Filing Summary

MHR Fund Management and affiliated entities have updated their disclosure of large holdings in Telesat Corporation’s Class B Variable Voting Shares through Amendment No. 2 to their Schedule 13D. Based on 51,003,269 Issuer Voting Securities outstanding, MHR Fund Management may be deemed to beneficially own 18,035,092 Class B Shares, representing 35.4% of this class, while Mark H. Rachesky, M.D. may be deemed to beneficially own 18,096,228 Class B Shares, or 35.5%.

The amendment reflects a continuation vehicle transaction completed on July 8, 2026, in which Institutional Partners II, Institutional Partners IIA and Institutional Partners III transferred Class B Units to newly formed vehicles SAT Holdco A, SAT SubHoldco A, SAT Holdco B and SAT SubHoldco B, and to MHR Sun II, MHR Sun IIA and MHR Sun III, depending on whether limited partners chose cash or rollover options. These new vehicles are managed by MHR Fund Management and ultimately controlled by entities associated with Dr. Rachesky and funded in part by RenWave Kore–affiliated funds and MHR Sun Holdings.

A side letter gives the Lead Investor the right to identify one Telesat director candidate for designation under the existing Investor Rights Agreement and establishes liquidity protections, including a Minimum Liquidity Threshold requiring proceeds to the Lead Investor of 125% of its capital contributions, with rights to trigger sales or wind-down steps if that threshold or later realization milestones are not met. The filing also notes that Institutional Partners IIA and Institutional Partners III each ceased to be beneficial owners of more than five percent of the Class B Shares as of July 8, 2026.

Insights

Amended 13D details a complex continuation vehicle deal while keeping effective Telesat control with MHR and Dr. Rachesky.

The amendment shows MHR Fund Management and affiliates consolidating Telesat exposure into new continuation vehicles holding Class B Units and Shares. Fund Management is reported as beneficial owner of 18,035,092 Class B Shares, and Mark H. Rachesky at 18,096,228, each around 35% of the class.

The CV Transaction moved interests from legacy funds (Institutional Partners II, IIA and III) into newly formed SAT Holdco/SubHoldco entities and MHR Sun vehicles, while offering limited partners cash or rollover options. Control remains with entities managed by Fund Management and overseen via MHR Sun GP, the Trust, and other Rachesky-controlled entities.

A side letter with the Lead Investor adds governance and liquidity features: a right to have one board designee while Fund Management retains two designation rights, a 125% Minimum Liquidity Threshold on the Lead Investor’s capital, and structured rights to force sales or wind-down steps if liquidity or realization targets are not achieved by dates tied to the fifth anniversary and seven-year fund terms. Overall, this is a material ownership-structure clarification rather than a clear directional signal on Telesat’s fundamentals.

MHR Fund Management beneficial ownership 18,035,092 Class B Shares Approximately 35.4% of Class B Shares outstanding
Mark H. Rachesky beneficial ownership 18,096,228 Class B Shares Approximately 35.5% of Class B Shares outstanding
MHR Sun GP stake 6,742,088 Class B Shares Approximately 13.2% of Class B Shares outstanding

Lead Investor deferred share units 42,856 units Deferred share units held by Dr. Rachesky, convertible into Class B Shares and/or cash
continuation vehicles financial
"transferred the Class B Units held by them to certain continuation vehicles that continue to be controlled by Dr. Rachesky"
A continuation vehicle is a new investment entity set up to buy one or more assets from an existing private equity or venture fund so managers can keep running those assets for longer. For investors this matters because it changes when and how they get cash, what valuation they accept, and what fees or oversight apply; think of it like moving a property you still want to manage into a new ownership structure so some owners can cash out while others stay invested.
Minimum Liquidity Threshold financial
"If the Minimum Liquidity Threshold (as described below) is not satisfied on or prior to the date"
A minimum liquidity threshold is the smallest amount of cash or easily tradable assets, or the minimum trading activity, that an entity or security must maintain to meet obligations, satisfy regulators or stay viable in markets. Investors care because falling below that line makes it harder to buy or sell without large price swings, raises the chance of missed payments or forced asset sales, and signals higher risk—like running low on fuel before reaching the next station.
Investor Rights Agreement financial
"Fund Management has the right to designate two individuals to be appointed as a director on the board of directors of the Issuer pursuant to the Investor Rights Agreement"
A legally binding contract between a company and its investors that spells out investors’ core protections and privileges—such as voting rights, how and when shares can be sold, information access, and steps for resolving disputes. Think of it like a rulebook or homeowner association agreement for ownership: it clarifies who gets a say, how value can be realized, and what protections exist if things go wrong, making investment risks and expectations clearer for shareholders.
side letter financial
"entered into a side letter (the "Side Letter") that provides, among other things, as follows"
tag-along rights financial
"the tag-along rights set forth in the Registration Rights Agreement ... would be of no further force or effect"
carried interest financial
"subject to fulfilling MHR Sun GP's entitlement to carried interest"
Carried interest is a share of the profits earned by investment managers from the investments they oversee, serving as their reward for successful performance. It functions like a bonus that motivates managers to maximize returns for investors, similar to earning a commission based on performance. This income is often taxed at a lower rate than regular income, making it a significant aspect of investment compensation.
