These technological advancements are critical for driving long-term revenue growth, expanding market opportunities, and reinforcing Iridium's competitive advantages.

Performance and Outlook: A Story of Growth and Prudent Capital Deployment

Iridium delivered a strong financial performance in the third quarter of 2025, reflecting the effectiveness of its strategic initiatives. Operational EBITDA increased 10% year-over-year to $136.6 million, driven by robust recurring services revenue and expanding engineering and support contracts. Total revenue for the quarter grew 7% to $226.9 million. Commercial services revenue rose 4% to $138.3 million, primarily propelled by growth in IoT data, voice and data, and hosted payload and other data services.

Commercial IoT revenue, a key growth driver, increased 7% to $46.7 million, supported by a 5% rise in billable subscribers to 1.99 million and a significant contract with a large customer. Hosted payload and other data services revenue saw a 14% increase to $18.7 million, largely due to growing PNT contributions. Voice and data revenue grew 4% to $59.9 million, benefiting from price increases that pushed ARPU to $48. Engineering and support services revenue surged 31% to $40.2 million, primarily due to increased work with the Space Development Agency (SDA). Net income for the quarter was $37.1 million, a substantial 52% improvement from the prior year.

For the nine months ended September 30, 2025, total revenue reached $658.7 million, up 7% from the prior year, with net income at $89.5 million, an increase of 17%. While commercial broadband revenue experienced a 17% decline in Q3 2025 due to a non-recurring revenue recognition in the prior year and a shift to companion services, this segment is a smaller portion of the overall business.

Iridium's liquidity and capital management reflect a disciplined approach. As of September 30, 2025, the company held $88.5 million in cash and cash equivalents, with a net leverage of 3.5x OEBITDA. The company's Term Loan, with $1.77 billion outstanding, matures in September 2030, and no quarterly principal payments are required until Q4 2026 due to an excess cash flow payment made in May 2025. Capital expenditures are projected to be approximately $90 million in 2025, primarily supporting Iridium NTN Direct development and 5G standards work, with moderation expected thereafter.

In a strategic move to enhance financial flexibility amidst evolving competitive dynamics, Iridium announced a pause in its share repurchase program in Q3 2025. This decision, while still committing to a growing quarterly dividend (increased to $0.15 per share in Q3 2025), is intended to emphasize strategic growth initiatives and deleveraging. Management anticipates this pause will add approximately $50 million to its cash position by year-end 2025, potentially accelerating deleveraging below 2x net leverage well before the targeted 2030 timeline, absent acquisitions.

For the full year 2025, Iridium has tightened its service revenue growth forecast to approximately 3% and narrowed its OEBITDA guidance to between $495 million and $500 million, at the higher end of its previous range. This adjustment primarily reflects a delay in the timing of PNT revenue, now expected in future periods, and a faster-than-anticipated shift in maritime broadband to companion services. Despite withdrawing its 2030 service revenue outlook due to increased competitive uncertainty, Iridium remains confident in generating at least $1.5 billion to $1.8 billion in free cash flow from 2026 through 2030. This robust cash flow underpins its ability to fund ongoing investments and shareholder returns.
