Iridium Communications Inc. (IRDM) experienced a significant pre-market decline of 5.15% following the release of its fourth-quarter 2025 financial results and 2026 guidance.

The satellite communications company reported Q4 revenue of $212.94 million, which fell short of the IBES estimate of $218.2 million. While the company posted a net income of $24.865 million for the quarter and noted a 5% increase in full-year operational EBITDA to $495.33 million, the revenue miss appears to have disappointed investors.

Further contributing to the negative sentiment was the company's outlook for 2026, projecting service revenue growth to be flat to just 2%. This conservative forecast, combined with the quarterly revenue shortfall, likely drove the pre-market sell-off as investors reassessed near-term growth expectations.
