memorandum of understanding regulatory

"announced the signing of a non-binding Memorandum of Understanding"

A memorandum of understanding (MOU) is a formal agreement between two or more parties that outlines their shared intentions and plans to work together. It acts like a handshake in writing, clarifying each side’s roles and expectations before any official contract is signed. For investors, an MOU signals that parties are serious about collaboration, which can influence future business opportunities and potential growth.

satellite bus technical

"providing satellite bus technology and licensing"

The satellite bus is the core structure and set of systems that support a satellite’s mission—power, propulsion, thermal control, communications, and mounting points for the mission payload. Think of it like the chassis and engine of a car that houses and keeps the mission equipment working; it matters to investors because its design dictates a satellite’s cost, reliability, lifespan and how much payload capability or flexibility the operator can offer.

Collaboration to focus on satellite technology transfer, in-country assembly, integration and test capability, and workforce development

CAPE CANAVERAL, Fla., Sept. 17, 2026 /PRNewswire/ -- Sidus Space, Inc. (NASDAQ: SIDU), (the "Company" or "Sidus"), an innovative space and defense technology company, today announced the signing of a non-binding Memorandum of Understanding ("MOU") with 3GM Plus, a Slovenian company headquartered in Ljubljana, to collaborate on satellite manufacturing, technology licensing, and the establishment of a domestic small satellite capability in Slovenia. The MOU was signed in Paris during World Space Business Week.

Under the MOU, 3GM Plus will serve as prime contractor for Slovenian satellite programs, with Sidus supporting as subcontractor providing satellite bus technology and licensing, engineering development and knowledge transfer, and flight-proven hardware including the Company's Fortis VPX Maxima digital mission computing platform. 3GM Plus selected Sidus based on the Company's demonstrated space heritage, including the design, manufacture, and on-orbit operation of its LizzieSat satellites.

"Europe is investing in sovereign space and defense capability at a pace we haven't seen before, and Slovenia has decided to build that capability rather than buy it," said Carol Craig, Founder, Chief Executive Officer and Chairman of Sidus Space. "That plays directly to how Sidus is structured. We can license technology, supply Fortis VPX Maxima and key subassemblies, and support Slovenia's own build instead of only delivering a finished spacecraft. Our objective here is to be a long-term partner in a national program, not a one-time supplier."

The parties anticipate a phased approach in which Sidus supports initial satellite development at its Cape Canaveral, Florida facility, with Slovenian engineering personnel participating directly in the build, followed by the establishment of assembly, integration and test capability in Slovenia. 3GM Plus would lead the development of that facility, applying its experience in the design and construction of cleanroom and controlled-environment systems to satellite manufacturing requirements.

The MOU further details structured knowledge transfer to Slovenian personnel, including hands-on engineering participation, onsite support during integration, and training for defense and civil mission operations.

Slovenia has the engineering talent and the industrial base to support a national satellite program, but not the flight experience," said Jure Milošević, Chief Executive Officer of 3GM Plus. "We selected Sidus because they have designed, built, and flown their own satellites. That heritage is what allows us to establish this capability in Slovenia on a credible timeline rather than starting from the beginning. Our objective is for Slovenia to become a producer within the European space supply chain, not only a customer."
