Item 9.01 Financial Statements and Exhibits Exhibits
Financial statements, pro forma financial information, and exhibit attachments filed with this report.
Vigoride-7 separation altitude approximately 520 km Altitude after separation from SpaceX’s Transporter-16 mission
Press release date April 13, 2026 Date Momentus shared Vigoride-7 mission achievements
Mission phase early-phase operations Described as one of the most successful early phases in company history
Next maneuver orbit-lowering Planned maneuver to prepare Vigoride-7 for payload operations
Orbital Service Vehicle technical
"the Vigoride-7 Orbital Service Vehicle powered on autonomously"
An orbital service vehicle is a spacecraft that acts like a tow truck and mobile mechanic in orbit: it approaches, inspects, repairs, refuels, relocates or removes other satellites and space debris instead of launching replacements. For investors, these vehicles can lower costs and extend the revenue life of satellites, create new service markets and revenue streams, and change risk profiles for satellite operators and insurers, affecting valuations across the space industry.
Transporter-16 mission technical
"Following separation from SpaceX’s Transporter-16 mission at approximately 520 km altitude"
hosted payloads technical
"Early communication verified the spacecraft and its hosted payloads are healthy"
Hosted payloads are additional instruments or equipment that a third party places aboard a primary satellite or spacecraft, effectively renting space and power instead of launching their own vehicle. For investors, they matter because they reduce launch costs and spread risk for the host operator while creating steady fee income or shared expenses for the customer, much like subleasing a room on a long road trip to save money and make the journey profitable.
in-orbit services technical
"specializing in satellite technology, space transportation, and in-orbit services"
forward-looking statements regulatory
"This press release contains certain statements which may constitute “forward-looking statements”"
Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

Vigoride-7 Fires All Thrusters and Clears Key Milestones

Momentus Marks Technical Achievements as Vigoride-7 Prepares for Payload Operations

SAN JOSE, Calif. — April 13, 2026 — Momentus Inc. (NASDAQ: MNTS) (“Momentus” or the “Company”), a U.S. commercial space company specializing in satellite technology, space transportation, and in-orbit services, today shared a series of significant achievements in the ongoing Vigoride-7 mission, marking one of the most successful early-phase operations in the company’s history.

Following separation from SpaceX’s Transporter-16 mission at approximately 520 km altitude, the Vigoride-7 Orbital Service Vehicle powered on autonomously, deployed its solar arrays, and executed initial configuration as designed.

Within hours, Momentus established two-way communication between Vigoride-7 and our San Jose based Mission Operations Center. Early communication verified the spacecraft and its hosted payloads are healthy. Comprehensive bus system checks validated that primary and redundant subsystems for power, command & data handling, and attitude control were fully operational.

Our major milestones to date include:


 •
Pressurization of the main water-based propulsion tank to mission-required levels


•
Activation of the Reaction Control Subsystem (RCS) accumulators, responsible for pressure regulation of 8 redundant RCS thrusters, providing fine attitude control


•
Attitude Control System (ACS) successfully dampened out our spacecraft’s rotation rates as we prepare to perform an initial orbit adjustment prior to commencing payload operations.

Achieving these milestones paves the way for the next phase of the mission: a planned orbit-lowering maneuver that will position Vigoride-7 for upcoming payload operations.

Momentus CEO, John Rood said “This mission is action-packed, technically demanding, and deeply rewarding,”

Momentus will continue to release progress reports as the mission unfolds over the coming weeks.
