Iridium Communications Inc. (IRDM) - Canvas Business Model: Customer Segments

You're looking at the core groups Iridium Communications Inc. serves, the ones that drive that recurring service revenue. Honestly, it's a split between the most demanding government users and a rapidly expanding commercial base, especially in the machine-to-machine space.

The U.S. Government and international defense/civil agencies represent a bedrock customer segment. This group relies on the Enhanced Mobile Satellite Services (EMSS) contract for mission-critical communications. For the contract year beginning September 15, 2025, the fixed-price rate for this EMSS Contract stands at $110.5 million annually. Beyond the airtime, Iridium secured a follow-on 5-year System Infrastructure Transformation and Hybridization (SITH) contract from the U.S. Space Force with a potential value up to $85.8 million to upgrade core ground facilities. As of September 30, 2025, the U.S. government business had 124,000 total subscribers.

Here's a quick breakdown of that government segment as of the end of the third quarter of 2025:

Government Sub-Segment	Subscribers (as of Q3 2025)	Notes
Total Government Subscribers	124,000	Down from 141,000 year-over-year
Government Voice and Data	45,000	Decreased 29% from the year-ago period
Government IoT Data Percentage	64%	Percentage of total government subscribers

The growth engine is clearly the Commercial Internet of Things (IoT) users. This segment is driving the overall subscriber count higher, even as voice subscribers see some pressure. Iridium ended the third quarter of 2025 with 2,542,000 total billable subscribers across the board, a 2% increase year-over-year. The commercial base specifically stood at 2,418,000 billable subscribers. IoT data subscribers made up 82% of that commercial base at the end of Q3 2025. To be fair, the commercial IoT data revenue grew 7% to $46.7 million, fueled by a 5% growth in those specific subscribers. If you calculate it, that puts the IoT user count around 1,982,760 based on the commercial total and the reported percentage.

Then you have the traditional maritime, aviation, and land mobile users who need reliable, mission-critical voice and data connectivity globally. These users are part of the broader commercial base that relies on Iridium's products as integral to their daily operations. Commercial voice and data subscribers were reported at 411,000 as of Q3 2025, generating revenue of $59.9 million for the quarter.

This core connectivity need extends deeply into remote industrial sectors. Iridium's customer base is diverse, explicitly naming several heavy-use industries that require coverage where terrestrial networks simply don't reach. You see this demand across:

• Oil & Gas exploration
• Mining activities
• Forestry management
• Construction sites

These sectors depend on Iridium's global reach for situational awareness and asset tracking in harsh environments. Finance: draft 13-week cash view by Friday.

Iridium Communications Inc. (IRDM) - Canvas Business Model: Cost Structure

You're looking at the core expenses that keep Iridium Communications Inc.'s global network running and how they manage their financial obligations as of late 2025. Honestly, the structure is heavily weighted toward keeping that 66-satellite constellation operational.

Fixed costs dominate the structure, primarily driven by the satellite operations and network maintenance, which are necessary regardless of short-term revenue fluctuations. The largest components here are the ongoing operational costs and the depreciation of the massive asset base. For the third quarter of 2025, the Cost of services (exclusive of depreciation and amortization) was $50.762 million, and Depreciation and amortization stood at $52.975 million. These two items alone represent a significant, largely fixed base cost.

Capital deployment remains a focus, though the major constellation build is complete. Capital expenditures (CapEx) for Q3 2025 were $21.5 million, which included $1.1 million in capitalized interest. This CapEx reflects investment in sustaining the network and new service rollouts, rather than the multi-billion dollar build of the previous decade.

Debt management is another key cost area. Iridium Communications Inc. ended Q3 2025 with net leverage at 3.5 times OEBITDA, meeting the goal of reducing net leverage below 3.5x OEBITDA in 2025. The associated debt servicing costs, specifically the net interest expense for Q3 2025, totaled ($22.593 million).

On the tax front, Iridium Communications Inc. benefits from past capital investments. The low cash tax expense is projected to remain minimal, guided at less than $10 million per year through 2027.

The company also incurs costs directly tied to its non-recurring revenue streams, specifically equipment sales and engineering projects. For context, Q3 2025 revenue from equipment sales was $21.507 million, and revenue from engineering and support service was $40.185 million. The associated costs are detailed below.

Here's a quick math look at the Q3 2025 operating expense breakdown (amounts in thousands):

Expense Category	Q3 2025 Amount (in thousands)
Cost of services (exclusive of D&A)	50,762
Depreciation and amortization	52,975
Selling, general and administrative	35,508
Cost of subscriber equipment sales	12,661
Research and development	4,944

The costs associated with the equipment and project segments are distinct from the core service delivery. You can see the direct cost tied to equipment sales versus the much larger cost of core services.

• Cost of subscriber equipment sales in Q3 2025 was $12.661 million.
• Selling, general and administrative expenses for Q3 2025 were $35.508 million.
• Research and development expenses for the quarter were $4.944 million.

The recurring nature of the service revenue, which was 73% of total revenue in Q3 2025 at $165.2 million, helps smooth out the impact of these fixed and project-related costs. Finance: draft 13-week cash view by Friday.

The model leans heavily on recurring service fees, which is exactly what you want to see in a satellite network business.

The core of the revenue picture is the Service Revenue, which was \$165.2 million for the third quarter of 2025. That number represents primarily recurring revenue from the growing subscriber base and was up 3% from the year-ago period. To give you a sense of scale, this service revenue made up 73% of the total revenue of \$226.9 million in Q3 2025.

Here's a quick breakdown of the Q3 2025 revenue components, which shows you where the dollars are actually landing:

Revenue Component	Q3 2025 Amount (Millions USD)	Notes
Total Revenue	\$226.9	A 7% increase versus Q3 2024.
Service Revenue (Recurring)	\$165.2	73% of Total Revenue.
Equipment Sales and Engineering/Support Projects	\$61.7	Non-recurring or project-based revenue.

Drilling down into that vital Service Revenue stream, it splits between commercial and government users. The Commercial Service Revenue was the dominant part, accounting for 61% of the total Q3 revenue, specifically hitting \$138.3 million. This segment saw a 4% growth year-over-year, driven by commercial IoT and price increases implemented earlier in the year.

On the other side, you have the Government Service Revenue, which includes the crucial Enhanced Mobile Satellite Services (EMSS) contract. For Q3 2025, this segment brought in \$26.9 million. That figure reflects contractual rate increases under the EMSS agreement, which has a fixed-price rate of \$110.5 million for the contract year beginning September 15, 2025. Government subscribers were at 124,000 at the end of the quarter.

The non-service portion of the business, Equipment Sales and Engineering/Support Projects, totaled \$61.7 million in Q3 2025. The Engineering & Support revenue specifically saw a significant jump, rising 31% year-over-year in the quarter, which is definitely something to watch as it often relates to new network deployments and government work.

Looking ahead, the company has reaffirmed its full-year 2025 expectations, which speaks to confidence in the recurring revenue base. The projection for full-year 2025 OEBITDA (Operational EBITDA, or earnings before interest, taxes, depreciation, and amortization) is set between \$495 million and \$500 million. This is an update from previous guidance, showing a slight narrowing at the low end, but still representing solid growth over the 2024 OEBITDA of $\$470.6$ million.

You can see the revenue mix clearly here:

• Service Revenue growth for full-year 2025 is projected at approximately 3%.
• Commercial service revenue was \$138.3 million in Q3 2025.
• Commercial IoT data revenue specifically reached \$46.7 million in Q3 2025.
• Commercial voice and data revenue was \$59.9 million in Q3 2025.
• The company ended Q3 2025 with 2,542,000 total billable subscribers.
