Major holders of Momentus Space
CITADEL ADVISORS LLCFiled SCHEDULE 13G/A on Momentus Space, latest Aug 14, 2026 (2 filings since Apr 22, 2026)
Built from major holders from Schedules 13D and 13G. Each entity in the chart links to its source.
What it owns
What Momentus Space reports owning in its annual reports to the SEC: buildings, land and equipment, real estate and locations, investments, intangible assets and inventory, at the end of its latest fiscal year and a year before.
Momentus subleases its office space in San Jose, California. Our primary facility is located at 1762 Automation Parkway, San Jose, California 95131. The sublease commenced on December 10, 2025, and runs for approximately 82 months (expiring September 30, 2032). These facilities are utilized by Momentus’ single reporting segment. We believe our current and committed space is sufficient to meet our needs for the foreseeable future.
Momentus was founded in 2017 by Mikhail Kokorich and Lev Khasis. The company gained early venture backing through Y Combinator and Prime Movers Lab based on its concept of a "space tug" that would transport small satellites from drop-off orbits provided by heavy-lift rockets to custom operational orbits using low-cost water plasma propulsion.
SPAC Merger and Regulatory Issues (2020–2022)
In October 2020, Momentus announced plans to become a public company via a SPAC merger with Stable Road Acquisition Corp. Prior to the merger's completion, the company faced significant regulatory intervention. The Committee on Foreign Investment in the United States (CFIUS) forced Kokorich, a Russian national, to step down due to national security concerns regarding foreign access to sensitive aerospace technology.
Concurrently, the U.S. Securities and Exchange Commission (SEC) charged Momentus and Stable Road with misleading investors regarding the success of a 2019 propulsion test. The company settled the charges for $7 million, overhauled its board of directors, and required the founders to divest their shares. Following compliance with a National Security Agreement (NSA), Momentus was cleared by the FAA to resume flight operations.
Defense Pivot and Stabilization (2023–Present)
In 2023, Momentus appointed John Rood as Chief Executive Officer. Under Rood's leadership, the company shifted its strategic focus toward complex government infrastructure projects, including autonomous rendezvous, proximity operations (RPO), and in-space assembly.
In January 2026, Momentus was selected as a qualified vendor for the Missile Defense Agency (MDA) SHIELD program, a multi-award contract vehicle with a $151 billion ceiling over ten years, marking the company's formal integration into major U.S. defense infrastructure planning.

Products and brands
Facilities
Momentus is headquartered in San Jose, California. In early 2026, the company completed the transition to its new Automation and Manufacturing Facility. This facility houses the company's primary cleanrooms, MET thruster testing vacuum chambers, and a dedicated Mission Control Center for active orbital operations.
Spacecraft and Technology
Vigoride Orbital Service Vehicle
The Vigoride is Momentus's primary spacecraft bus. Designed to launch as a payload on medium-to-heavy lift rockets (primarily the SpaceX Falcon 9 via the Transporter rideshare program), Vigoride operates in Low Earth orbit (LEO). Modern iterations of the Vigoride bus are capable of generating up to 3 kilowatts of peak solar power to support compute-heavy military sensors and robotic payloads.
Microwave Electrothermal Thruster (MET)
The Vigoride is propelled by a proprietary Microwave Electrothermal Thruster. The system uses solar arrays to power a microwave emitter, which turns liquid water propellant into superheated plasma. Water is utilized because it is non-toxic, easily stored without high-pressure cryogenic tanks, and presents a theoretical pathway for future in-situ resource utilization (ISRU) via asteroid or lunar ice mining.

Risk factors and legal proceedings
The risks Momentus Space names in Item 1A of its 10-K filed Mar 31, 2026: 56 risks under these headings, as written.15
Unless the context otherwise requires, all references to the “Company,” “we,” “us,” or “our” refer to Momentus and its subsidiaries.
Risks Related to the Business and Industry of Momentus
We will require substantial additional funding to finance our operations, but adequate additional financing may not be available when we need it, on acceptable terms, or at all.
We have incurred significant losses in the past, we expect to incur losses in the future, and we may not be able to achieve or maintain profitability.
We may not be able to continue as a going concern.
We have delivered customer satellites and payloads into orbit using our service vehicles since 2022, however setbacks experienced during our future missions could have a material adverse effect on our business, financial condition, and results of operation and could harm our reputation.
We are dependent on the successful development of our satellite and related technology.
We may not be successful in developing new technology, and the technology we are successful in developing may not meet the needs of our customers or potential new customers.
We operate in highly competitive industries and in various jurisdictions across the world which may cause us to have to reduce our prices.
Momentus’ limited operating history makes it difficult to evaluate its future prospects and the risks and challenges it may encounter.
The market for spaceflight and in-space infrastructure services has not been established with precision, is still emerging and may not achieve the growth potential we expect.
We may not be able to convert our customer contracts into revenue.
The other 45 risks
Our future revenue and operating results are dependent on our ability to generate a sustainable order rate for our products and services and develop new technologies to meet the needs of our customers or potential new customers.
The cyclical nature of the space industry could negatively impact our ability to accurately forecast customer demand. We may not be able to achieve or maintain adequate gross margins or profits in these markets.
We may experience a total loss of our satellites and Orbital Service Vehicle and our customers’ payloads during the launch into space, and any insurance we have may not be adequate to cover our loss.
Our business involves significant risks and uncertainties that may not be covered by insurance.
If our spacecraft fail to operate as intended, it could have a material adverse effect on our business, financial condition, and results of operations.
Increased congestion from the proliferation of low-Earth orbit constellations could materially increase the risks of potential collision with space debris or another spacecraft and limit or impair our launch flexibility and/or access to our own orbital slots.
Our revenue, results of operations and reputation may be negatively impacted if our products contain defects or fail to operate in the expected manner.
Fluctuations in foreign exchange rates or future hedging activities could in the future have a negative impact on our business.
We rely on a limited number of suppliers for certain raw materials, specialized labor, and supplied components. We may not be able to obtain sufficient raw materials, specialized labor, or supplied components to meet our manufacturing and operating needs or obtain such materials on favorable terms or at all, which could impair our ability to fulfill our orders in a timely manner or increase our costs of production.
Our satellites, vehicles, and related equipment may have shorter useful lives than we anticipate.
We expect to face intense competition in satellite production, satellite transport, and related services and other services which we may develop in the space transportation industry.
If we fail to adequately protect our intellectual property rights or our intellectual property applications for registration fail to become issued or registered, our competitive position could be impaired.
Protecting and defending against intellectual property claims may have a material adverse effect on our business.
We may experience warranty claims for failures, schedule delays or other problems with existing or new products.
We are exposed to risks related to geopolitical and economic factors, laws and regulations and our international business subjects us to numerous political and economic factors, legal requirements, cross-cultural considerations and other risks associated with doing business globally.
Data breaches or incidents involving our technology could damage our business, reputation and brand and substantially harm our business and results of operations.
We are highly dependent on our senior management team and other highly skilled personnel.
Our operating results may fluctuate significantly, which makes our future operating results difficult to predict and could cause our operating results to fall below expectations or any guidance we may provide.
Momentus’ ability to use its net operating loss carryforwards and certain other tax attributes may be limited.
We may in the future be subject to substantial litigation, regulatory actions, government investigations, proceedings, and similar actions that could cause us to incur significant legal expenses and which could have a material adverse effect on our business, operating results, or financial condition.
Natural disasters, unusual weather conditions, epidemic outbreaks, terrorist acts, and political events could disrupt our business and vehicle launch schedules.
Our restructurings and associated organizational changes may not adequately reduce our expenses, may lead to additional workforce attrition, and may cause operational disruptions.
The pursuit of additional capital and other strategic alternatives will consume a substantial portion of the time and attention of our management and require additional capital resources which may be disruptive to our business and could have a material adverse effect on our business, financial condition and results of operations.
Regulatory Risks
We are subject to stringent U.S. export and import control laws and regulations. Unfavorable changes in these laws and regulations or U.S. government licensing policies, our failure to secure timely U.S. government authorizations under these laws and regulations, or our failure to comply with these laws and regulations could have a material adverse effect on our business, financial condition and results of operations.
Momentus and its customers and suppliers could be materially impacted by disruptions in U.S. government operations and funding.
Changes in U.S. government policy regarding use of commercial data or space infrastructure / mission providers, or material delay or cancellation of certain U.S. government programs, may have a material adverse effect on our customers, suppliers, revenues, operational delays, earnings and cash flow and our ability to achieve our growth objectives.
Contracts with the U.S. government subject us to risks including early termination, audits, investigations, sanctions, and penalties.
Failure to comply with federal, state and foreign laws and regulations relating to privacy, data protection and consumer protection, or the expansion of current or the enactment of new laws or regulations relating to privacy, data protection and consumer protection, could adversely affect our business and our financial condition.
Risks Related to Ownership of our Class A Common Stock
If we fail to comply with the continued listing requirements of Nasdaq we face possible delisting, which would result in a limited public market for our shares and make obtaining future debt or equity financing more difficult for us.
Our outstanding warrants could dilute stockholders, depress our stock price, reduce proceeds available to holders of our Class A common stock in a change of control, and impede a potential acquisition of the Company.
Our outstanding convertible notes, and a potential additional investment under an existing note facility, may result in significant dilution to our stockholders and could adversely affect the market price of our Class A common stock.
An active trading market for our Class A common stock may never develop or be sustained.
The market price of our Class A common stock and warrants may be volatile, which could cause the value of your investment to decline.
Future sales of shares by Company officers, directors and other insiders may adversely affect the market price of our Class A common stock.
Future sales of shares by existing stockholders may adversely affect the market price of our Class A common stock.
If securities and industry analysts do not publish research or reports, or publish inaccurate or unfavorable research or reports, about our business or our market, our stock price and trading volume could decline.
Our charter documents and Delaware law could prevent a takeover that stockholders consider favorable and could also reduce the market price of our Class A common stock.
Our Second Amended and Restated Certificate of Incorporation, as amended, provides that a state or federal court located within the state of Delaware will be the exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a chosen judicial forum for disputes with us or our directors, officers, employees, or stockholders.
Future sales and issuances of our Class A common stock could cause our stock price to fall.
Sales of Class A common stock under our “at-the-market” (“ATM”) program and our equity line of credit (“ELOC”) could result in substantial dilution to stockholders, depress the market price of our Class A common stock, and may not provide adequate funding when needed.
We need additional capital and any additional capital we seek may not be available in the amount or at the time we need it.
The market price of our Class A common stock has been, and may continue to be, volatile, which could reduce the market price of our Class A common stock.
General Risks
Our employees and independent contractors may engage in misconduct or other improper activities, which could have an adverse effect on our business, prospects, financial condition, and operating results.
Labor-related matters, including labor disputes, may adversely affect our operations.
Changes in our accounting estimates and assumptions could negatively affect our financial position and results of operations.
Legal proceedings
From time to time, we may be subject to various claims, lawsuits, and other legal and administrative proceedings that may arise in the ordinary course of business. Some of these claims, lawsuits, and other proceedings may range in complexity and result in substantial uncertainty; it is possible that they may result in damages, fines, penalties, non-monetary sanctions, or relief. However, we do not consider any such claims, lawsuits, or proceedings currently pending, individually or in the aggregate, likely to result in a material adverse effect on our future operating results, financial condition, or cash flows.
