Business Overview
Spire Global operates a satellite constellation providing space-based data, analytics, and intelligence services, primarily focused on weather forecasting, radio frequency geolocation (RFGL), and space services. The company generates revenue by selling data subscriptions and contracts to government, defense, and commercial customers. Its major segments include core satellite data services, RFGL offerings, and previously a maritime business divested in 2025.
Performance Analysis
Spire reported $18.0 million in GAAP revenue for Q2 2026, reflecting a 6% year-over-year decline primarily due to the divestiture of its maritime business. Excluding maritime, core revenue grew 16% year-over-year and 19% sequentially, marking the strongest quarter since the divestiture. This growth was driven by increased delivery of space services data and higher RFGL data purchases, signaling robust demand across multiple markets.
Gross margins compressed to 38% on a non-GAAP basis, down 14 percentage points year-over-year, largely impacted by the cancellation of the WildFireSat contract. Despite margin pressure, adjusted EBITDA improved 16% year-over-year and 15% sequentially to negative $8.6 million, reflecting disciplined cost management. Operating cash flow usage improved 32% year-over-year to negative $23.4 million, with expectations for continued sequential improvement through the remainder of 2026.
- Revenue Growth Drivers: Core revenue growth was supported by government weather contracts, including NOAA and international awards, and expanding RFGL subscriptions.
- Margin Pressure Factors: WildFireSat contract cancellation and related balance sheet adjustments temporarily suppressed gross margin expansion.
- Cash Flow Improvement: Lower operating expenses and operational efficiencies contributed to a 32% year-over-year reduction in cash flow burn.
Collectively, these results illustrate a business gaining operational traction with a growing revenue base and improving financial discipline, setting the stage for expected margin expansion and adjusted EBITDA breakeven by late 2026 or early 2027.
Executive Commentary
"Revenue for the second quarter was $18 million. Excluding the maritime business we divested last year, core revenue expanded both year-over-year and sequentially, marking our strongest core revenue quarter since the divestiture... We are currently in the negotiation phase on an eight-figure contract opportunity tied to our hyperspectral microwave sounding capability... We secured awards from four new international customers in the second quarter, on top of the five new US awards and three new international customers we reported in the first quarter."
Theresa Condor, Chief Executive Officer
"Revenue remains the metric we watch most closely because it reflects execution across both sales and operations, and it's the primary driver of our financial progress... Second quarter GAAP revenue was $18 million, up 16% year-over-year on a core basis excluding maritime, and up 19% sequentially... Adjusted EBITDA was negative $8.6 million, an improvement of 16% year-over-year and 15% sequentially, primarily driven by lower operating expenses... We continue to expect adjusted EBITDA break even by late 2026 to early 2027."

Strategic Positioning
1. Accelerating Government Weather Contracts
Spire’s pipeline with NOAA and other government agencies is advancing, highlighted by a $5 million Hyperspectral Microwave Founder data extension and an eight-figure contract in negotiation. The company expects the upcoming renewal of its Radio Occultation (RO) contract to exceed last year’s $11.2 million award, with a multi-phase bridge and longer-term award anticipated. These contracts underpin a forecasted 50% core revenue growth for 2026 and reflect increasing government reliance on commercial space data.
2. Expanding RF Geolocation Business
Demand for Spire’s Radio Frequency Geolocation (RFGL) services is rising amid a contested global RF environment with widespread jamming and spoofing. The company reported a tenfold increase in RFGL capacity year-to-date, driven by new satellite pairs and ongoing constellation upgrades. With four new international customers added in Q2 and multiple pilot-to-subscription conversions underway, Spire is building a durable, multi-year runway in this strategic segment.
3. Manufacturing Footprint and Operational Scale
Spire’s new satellite manufacturing facility in Munich complements existing operations in North America and the UK, enabling an annual production capacity of 300 to 400 satellites.
