Spire Global, Inc. (SPIR) Stock Analysis

Spire Global designs, builds, and operates its own constellation of LEMUR nanosatellites — more than 200 launched since inception, with over 75 expected in orbit by the end of 2026 — feeding data into four business lines: space reconnaissance, aviation tracking, weather and climate forecasting, and Space Services. Three government customers accounted for approximately 43% of fiscal 2025 revenue, a concentration underscored in April 2026 when the Canadian government terminated for convenience Spire's WildFireSat satellite contract, worth up to Can$71.8 million if fully performed. The company employed 377 people across 9 countries as of December 31, 2025, none unionized.

Spire monetizes four tiers of data — clean, smart, predictive, and full data solutions — sold on a subscription basis with a land-and-expand model that grows revenue per customer over time, plus Space Services contracts that let other companies deploy their own payloads on Spire's satellite platform and ground-station network for a recurring fee rather than a large upfront capital outlay. On April 25, 2025, the company sold its maritime AIS-tracking business to Kpler Holding for approximately $238.9 million, using part of the proceeds to settle a dispute with L3Harris Technologies and repay its Blue Torch Finance and Strategic Innovation Fund credit facilities; it retained only the maritime services tied to U.S. federal government customers, which it expects to wind down over time. Named competitors vary by vertical — Aireon in aviation, PlanetiQ in weather/radio occultation, HawkEye360 in space reconnaissance, and Muon Space in Space Services — and the company's data business depends on continued FCC and foreign-regulator licensing of its satellite frequencies and earth stations.
