Key Terms

indefinite delivery/indefinite quantity (IDIQ), enhanced mobile satellite services (EMSS), low-earth orbit (LEO), proliferated warfighter space architecture (PWSA), +2 more

6 terms

indefinite delivery/indefinite quantity (IDIQ) regulatory

"it has been awarded a 5-year indefinite delivery/indefinite quantity (IDIQ) contract"

An indefinite delivery/indefinite quantity (IDIQ) is a type of contract that lets a buyer commit to buy goods or services over a set period without specifying exact quantities or delivery dates up front, while setting minimums and maximums. Think of it like a grocery standing order where you agree to buy up to a certain amount but the timing and exact amounts are decided later. For investors, IDIQs matter because they can create a predictable revenue stream and backlog while leaving some uncertainty about timing and total value, affecting earnings visibility and cash flow planning.

enhanced mobile satellite services (EMSS) technical

"enhancements to the Enhanced Mobile Satellite Services (EMSS) Service Center"

Enhanced mobile satellite services (EMSS) are satellite-based communication systems that provide voice, text and data to users on the move or in remote locations using specialized satellites and handheld or vehicle-mounted devices. Investors care because EMSS involves spectrum rights, satellite and ground equipment sales, subscription revenue and partnerships with mobile carriers — much like owning the pipes and toll booths for connectivity in places where regular cell service can't reach.

low-earth orbit (LEO) technical

"Powered by the only truly global low-Earth orbit (LEO) network"

Low-Earth orbit (LEO) is the band of space closest to Earth where satellites and spacecraft circle the planet, roughly between about 160 and 2,000 kilometers up—imagine a busy low-altitude highway around the globe. It matters to investors because many communications, imaging, and data services rely on satellites there, so developments in launch costs, satellite technology, traffic and regulation can directly affect companies’ revenues, costs and risk profiles.

proliferated warfighter space architecture (PWSA) technical

"segment for Tranche 1 of the Proliferated Warfighter Space Architecture (PWSA)"

A proliferated warfighter space architecture (PWSA) is a military approach that uses many small, networked satellites and ground systems instead of a few large spacecraft to deliver communications, navigation, and sensing for combat forces. Think of it like replacing a single central power plant with a neighborhood of solar panels: the result is harder to disable, can be scaled up quickly, and lets operators reroute around failures. For investors, PWSA signals demand for builders, launch providers, ground equipment, and cyber-resilience services tied to defense budgets and procurement programs.

operations and integration (O&I) technical

"works to establish the ground Operations and Integration (O&I) segment"

Operations and integration (O&I) is the team and process that combines an acquired or merged business with the buyer’s existing operations—aligning systems, processes, people, facilities and supply chains so both parts run together smoothly. Investors care because effective O&I turns projected savings and new revenue into reality, while poor execution can cause disruptions, extra costs or lost sales; think of it as merging two kitchens so meals keep coming without wasting ingredients or staff time.

p.a.c.e. technical

"the warfighter's P.A.C.E. (Primary, Alternate, Contingency, Emergency) plan"

p.a.c.e. (often written PACE) is a financing program that lets property owners pay for energy efficiency, renewable energy, or storm-resilience upgrades through a special assessment added to their property tax bill. For investors, PACE matters because it creates a long-term, tax-backed payment stream tied to the property rather than the owner, which can affect the credit quality of loans, the value of properties, and the risk profile of investments tied to real estate or municipal securities — think of it as a mortgage-style charge specifically for green upgrades.

New Contract Supports Enhancements to the Iridium and U.S. DoD EMSS Service Center and Related Facilities

MCLEAN, Va., Dec. 2, 2025 /PRNewswire/ -- Iridium Communications Inc. (NASDAQ: IRDM), a leading provider of global voice, data, and PNT satellite services, today announced it has been awarded a 5-year indefinite delivery/indefinite quantity (IDIQ) contract from United States Space Force's (USSF) Space Systems Command Commercial Space Office (COMSO) with a potential value of up to $85.8 million.  

The System Infrastructure Transformation and Hybridization (SITH) contract enables technological refreshes, lifecycle upgrades, and security enhancements to the Enhanced Mobile Satellite Services (EMSS) Service Center, Technical Support Center (TSC), and Defense Ground Station (DGS). SITH is a follow-on contract to the Gateway Evolution Contract awarded to Iridium in 2019. 

The Iridium^® network provides resilient, mission-critical communications that warfighters need—anywhere in the world, even under adverse weather conditions. SITH is the latest of three core EMSS contracts between Iridium and the USSF. The EMSS Airtime Contract delivers unmatched truly global SATCOM connectivity, offering unlimited access for an unlimited number of DoD and federal government users. Meanwhile, through the Capabilities and Security Sustainment Services Contract (ECS3) awarded in April 2024, Iridium helps ensure the EMSS Service Center and DGS remain at peak performance.

"Through this contract, Iridium and the U.S. Space Force will continue to innovate and deliver resilient, secure and highly reliable mission-critical communications," said Scott Scheimreif, executive vice president, Iridium. "Our solutions with the Department of Defense are designed to serve every layer of the warfighter's P.A.C.E. (Primary, Alternate, Contingency, Emergency) plan. We look forward to supporting the U.S. and our allies through new technology introductions and ongoing collaboration."

Powered by the only truly global low-Earth orbit (LEO) network, Iridium's voice and data solutions elevate situational awareness for military forces and provide precise tracking of critical assets in the harshest environments—delivering a level of performance and reliability that is not easily duplicated. Additionally, the company's expertise in satellite operations and network management is integral as it works to establish the ground Operations and Integration (O&I) segment for Tranche 1 of the Proliferated Warfighter Space Architecture (PWSA).
