Iridium (IRDM) Q4 2025 earnings review
Growth Stalls: Equipment Drag and Broadband Erosion Halt Momentum
Iridium ended 2025 with a thud. Total revenue was flat YoY at $212.9M, a sharp deceleration from the mid-single-digit growth seen earlier in the year. While Commercial IoT remains a bright spot (+11%), it was insufficient to offset a 21% collapse in Equipment revenue and a 9% decline in Broadband. Profitability metrics deteriorated, with Net Income falling 31% and OEBITDA down 2%. The outlook for 2026 is sobering: Service Revenue is guided to be 'flat to 2%,' signaling that the growth pause is not merely a quarterly blip but a potentially longer-term stagnation.
🐂 Bull Case
Commercial IoT data revenue grew 11% YoY to $46.1M, accelerating from previous quarters. With subscriber growth of 6% to nearly 2M users and ARPU expanding to $7.70, this high-margin segment proves Iridium's niche dominance is intact.
Despite earnings headwinds, Iridium continues to deleverage (Net Leverage at 3.4x) and return capital. The company repurchased 6.8 million shares in FY25 and maintains $245M in buyback authorization, supported by a capex-light model.
🐻 Bear Case
Commercial Broadband revenue fell 9% YoY, driven by a 7% drop in ARPU ($250 vs $268). Customers are downgrading Iridium to 'companion' status alongside cheaper VSAT/Starlink options, a structural trend that is eroding high-value revenue.
Management guided 2026 Service Revenue growth to 'flat to 2%.' This is a major deceleration from the 5-7% long-term targets previously discussed. Combined with an OEBITDA guide that implies contraction (reported basis), the growth story is broken.
⚖️ Verdict: 🔴
Bearish. The growth engine has sputtered. While IoT is strong, the deterioration in Broadband ARPU and the collapse in Equipment sales have halted top-line expansion. Guidance for 2026 (0-2% growth) confirms this is a structural slowdown, not a one-off miss.
Key Themes
Equipment Revenue Collapse
Equipment revenue plummeted 21% YoY to $17.0M. While historically volatile, this magnitude of decline suggests channel inventory backing up or slowing end-user adoption of new hardware. This drags heavily on total revenue optics and often presages slower future service activation growth.
Broadband ARPU Compression
Commercial Broadband revenue fell 9% despite relatively stable subscriber counts (-3%). The issue is pricing: ARPU dropped to $250 from $268 a year ago. Management explicitly links this to 'increased prevalence of Iridium’s use in lower-priced companion plans.' Iridium is losing its status as a primary connection in maritime/aviation, relegated to a backup role for Starlink.
IoT Resilience
Commercial IoT remains the company's bedrock. Revenue grew 11% YoY, outpacing subscriber growth (+6%), which drove ARPU up to $7.70. As the broadband business faces commoditization pressure, the proprietary, low-bandwidth IoT business is displaying strong pricing power and demand.
Accounting Noise in 2026 OEBITDA
2026 OEBITDA guidance ($480-490M) looks like a decline vs 2025 ($495M). However, this includes a $17M headwind from shifting incentive comp from equity to cash. Adjusting for this, OEBITDA would be ~$502M (flat/slight up). Investors must look past the headline drop, though 'flat' adjusted growth is still uninspiring.
Profitability Squeeze
Net Income fell significantly, down 31% YoY ($24.9M vs $36.3M). OEBITDA margins compressed slightly. With revenue flat, the company is seeing negative operating leverage. Without top-line re-acceleration, bottom-line growth will depend entirely on cost cuts or buybacks.
Other KPIs
Reversing. Down 2% YoY from $117.1M. This is the first YoY decline in OEBITDA in recent quarters, breaking a streak of steady growth (Q1 +6%, Q2 +6%, Q3 +10%). The margin contraction reflects the mix shift away from high-margin broadband and equipment volumes.
Stable. Up 3% YoY due to contractual rate increases in the EMSS contract. While government voice/data subscribers fell 31% YoY (to 43k), the fixed-price nature of the EMSS contract protects revenue, decoupling it from subscriber counts.
Stable. Slight improvement from 3.5x in Q3, but still elevated compared to the long-term target of <2.0x. The company repaid its Revolving Facility in Q4. Deleveraging remains slow due to shareholder returns.
Guidance
Decelerating. This is a significant step down from the ~3% achieved in 2025 and well below the 5-7% range touted in prior years. It implies the headwinds in Broadband and flat Government revenue will largely offset IoT growth.
Decelerating/Reversing. Compared to 2025 actuals ($495.3M), this is a decline. However, management notes a $17M negative impact from changing comp structure to cash. Excluding this, the midpoint is ~$502M, representing <1.5% underlying growth.
Stable (at low levels). After the 11% drop in FY25, expecting 'in line' performance implies no recovery in hardware sales, merely a stabilization at a lower baseline.
Stable. The company maintains its tax shield guidance through 2027, protecting cash flow generation despite the GAAP earnings pressure.
Key Questions
Broadband Floor
With Broadband revenue down 9% and ARPU compressing, where is the floor? Are we approaching a point where the 'companion' plan transition is complete, or should we expect high-single-digit declines to persist throughout 2026?
Equipment Inventory Channel
Equipment revenue missed expectations significantly in Q4 (-21%). Is this a result of destocking by partners due to low demand, or is there a competitive hardware transition occurring that we aren't seeing?
Service Revenue Stagnation
Guidance for 2026 is 'Flat to 2%.' Given IoT is growing double-digits, this implies everything else is flat or negative. What specific segment is expected to perform worse in 2026 than in 2025 to drag the weighted average down this far?
