The Company has agreements with Macdonald, Dettwiler and Associates Corporation ("MDA Space") and Space Exploration Technologies Corp. ("SpaceX") for 1) the purchase and launch of the satellites that are intended to replace the Company's HIBLEO-4 U.S.-licensed system and 2) the purchase and launch of third-generation satellites to support the Extended MSS Network. Refer to Note 9: Commitments and Contingencies for additional information regarding these agreements.

As of September 30, 2026, in connection with the construction and launch preparation of the replacement satellites, the Company has incurred $303.2 million and $121.4 million in capital expenditures for milestones completed under the related agreements with MDA Space and SpaceX, respectively. Each of the replacement satellites will be placed into service and depreciation will begin after each such satellite has reached its intended orbital altitude and is providing commercial service. The first set of replacement satellites was launched in August 2026. As of September 30, 2026, in connection with the construction and launch preparation of the third-generation satellites to support the Extended MSS Network, the Company has incurred $529.5 million and $125.7 million for milestones completed under the related agreements with MDA Space and SpaceX, respectively. The costs related to the replacement and third-generation satellites, as well as the associated personnel costs and capitalized interest, are reflected in the "space component" of construction in progress in the table above.

In connection with the Extended MSS Network, the Company has procured ground equipment and other network assets to upgrade existing and build new ground stations globally. The costs to support this effort, such as construction, equipment, personnel and capitalized interest, are reflected in the "ground component" of construction in progress in the table above.
