Sidus Space Posts $29.5M Net Loss in 2025
Expands Satellite Fleet, Bolsters Cash Reserves
In its Full Year 2025 earnings report, Sidus Space Inc. reported a net loss of $29.5 million for the year, nearly double the prior year’s loss, as the space and defense technology company continued heavy investment in satellite operations and infrastructure while revenue declined 28% to $3.4 million.
“2025 was a pivotal year for Sidus as we continued executing our long-term strategy to build vertically integrated space and defense technology platforms.”

The NASDAQ-listed company (SIDU) said Tuesday the wider loss reflects costs tied to expanding its LizzieSat satellite fleet and building out AI-enabled data platforms, rather than a deterioration in its core business. The net loss compares to $17.5 million in 2024.
Despite the financial headwinds, Sidus ended the year with $43.2 million in cash — up from $15.7 million at the close of 2024 — following equity capital raises in the third and fourth quarters. The company said the strengthened balance sheet will fund development of its next two satellites, LizzieSat-4 and LizzieSat-5.
“2025 was a pivotal year for Sidus as we continued executing our long-term strategy to build vertically integrated space and defense technology platforms,” said Carol Craig, founder and CEO of Sidus Space. “We expanded our on-orbit capabilities with the successful launch and commissioning of LizzieSat-3, advanced our AI-enabled computing ecosystem, and strengthened our balance sheet through strategic capital raises that provide the resources needed to support future growth.”
Cost of revenue rose 48% year-over-year to $9.1 million, driven largely by depreciation on the expanding satellite fleet and labor supporting round-the-clock spacecraft operations. Gross loss widened to $5.7 million from $1.5 million in 2024. Adjusted EBITDA loss, a non-GAAP measure, totaled $17.3 million, compared to $12.9 million the prior year.
Among the year’s operational milestones, the company launched LizzieSat-3 in March 2025 and demonstrated on-orbit artificial intelligence processing through its Sidus Orlaith AI ecosystem. The company also amended its manufacturing agreement with Lonestar Data Holdings, increasing the total contract value to $120 million, and was awarded a 10-year indefinite delivery/indefinite quantity contract under the Missile Defense Agency’s SHIELD program, which carries a total potential ceiling of $151 billion.
Sidus also expanded its intellectual property portfolio to 15 issued patents and added two new members to its board of directors.
Looking ahead, the company said it expects depreciation costs to be offset as satellite and data-related revenue scales. A payload integration milestone with Maris-Tech Ltd. was announced after year-end, with a flight scheduled aboard the LS-4 mission expected to launch in the fourth quarter of 2026.
