Business Overview and Strategy

Iridium stands as a leading provider of global mobile satellite communications and data services, primarily serving critical sectors such as government, maritime, aviation, land mobile, and the Internet of Things (IoT). The company's core strength lies in its unique constellation of 66 cross-linked low-Earth orbit (LEO) satellites. This network enables truly global coverage, including the poles and oceans, without relying on ground infrastructure.

Key Strategic Pillars for 2025:

• Subscriber Expansion: Focused on growing both commercial and government subscribers across all segments, with particular emphasis on IoT and broadband services (Iridium Certus®).
• Service Enhancement: Invested in new product development and partnerships to broaden the utility and reach of its network.
• Operational Optimization: Maintained the reliability and efficiency of its satellite constellation and ground infrastructure.
• Revenue Diversification: Explored new applications and markets for its unique LEO capabilities.

Management's Discussion and Analysis (MD&A) Highlights

Management's discussion highlighted the strategic drivers behind the robust financial performance in 2025. Consistent subscriber additions across key segments, particularly IoT and government, combined with stable Average Revenue Per User (ARPU), primarily drove service revenue growth. The increase in net income and Adjusted EBITDA reflected effective cost management alongside revenue expansion, showcasing the company's operational leverage. Iridium's strong operating cash flow underscored its ability to self-fund ongoing operations and strategic capital expenditures, which aim to maintain network resilience and foster future technological advancements.

Key operational achievements included the continued adoption of Iridium Certus® and significant government contract extensions. Management emphasized these as crucial for sustaining market leadership and revenue stability. The successful testing of next-generation technologies was also noted as a foundation for future service enhancements and market expansion.

Operational Performance and Key Developments

• Iridium Certus®: Continued strong adoption of its broadband service, expanding its presence in maritime, aviation, and land mobile markets.
• Government Contracts: Secured a multi-year contract extension with the U.S. government, underscoring the critical nature of Iridium's services for national security.

Competitive Position

Iridium operates in a highly competitive global satellite communications market, facing various providers. Its primary competitive advantage stems from its unique cross-linked Low-Earth Orbit (LEO) satellite constellation. This network offers truly global, pole-to-pole voice and data coverage, including remote and oceanic regions where terrestrial infrastructure is absent. This differentiates Iridium from:

• Traditional Geostationary (GEO) satellite operators: These typically have higher latency and do not provide global coverage.
• Emerging LEO and Medium-Earth Orbit (MEO) constellations: These may target different market segments or offer varying service characteristics.

Iridium's strategy focuses on specialized, mission-critical applications in government, maritime, aviation, and industrial IoT sectors. This approach leverages its network's reliability and global reach, establishing a strong niche. Competition also arises from terrestrial wireless providers in areas with overlapping coverage and from specialized IoT connectivity solutions.

Risks and Challenges

Investors should consider several key risks outlined in the 10-K:

• Satellite Operations: Inherent risks associated with operating a complex satellite constellation, including potential for satellite failure, space debris, and launch risks.
• Competition: Intense competition from other satellite operators (LEO, MEO, GEO) and terrestrial communication providers.
• Technological Obsolescence: The need for continuous innovation to keep pace with rapidly evolving communication technologies.
• Regulatory Environment: Changes in spectrum allocation, licensing, or international telecommunications regulations could impact operations.
• Economic Conditions: Global economic downturns could affect customer spending and demand for services.

Iridium aims to continue leveraging its unique global network to expand its subscriber base, innovate its service offerings, and maintain its leadership in specialized satellite communications markets.
