Iridium Communications Inc. (IRDM) saw its stock price plummet 6.75% in pre-market trading on Thursday following the release of its second-quarter 2025 earnings report. The satellite communications company's results painted a mixed picture, with an earnings miss overshadowing a slight revenue beat.

Iridium reported quarterly earnings of $0.20 per share, falling short of the analyst consensus estimate of $0.24 by 15.25%. This represents a significant 25.93% decrease from the $0.27 per share reported in the same period last year. On a more positive note, the company's quarterly sales came in at $216.906 million, surpassing the analyst consensus estimate of $214.079 million by 1.32%. This figure also marks a 7.88% increase from the $201.067 million reported in the same quarter of the previous year.

Adding to investor concerns, Iridium revised its service revenue growth guidance for 2025 to 3%-5%, potentially signaling slower growth than previously anticipated. However, the company maintained its full-year 2025 OEBITDA and long-term guidance, suggesting confidence in its overall financial outlook despite near-term challenges. The combination of the earnings miss and lowered revenue guidance appears to have spooked investors, leading to the significant pre-market decline in Iridium's stock price.
