Momentus Inc. Announces Third Quarter 2022 Financial Results
SAN JOSE, CA – November 8, 2022 – Momentus Inc. (NASDAQ: MNTS) (“Momentus” or the "Company”), a U.S. commercial space company that offers transportation and other in-space infrastructure services, today announced its financial results for the third quarter ended September 30, 2022.
Momentus Chief Executive John Rood made the following comments about the quarter:
“This was another eventful quarter at Momentus. Our talented engineering and operations team made solid progress during the quarter in our research and development efforts taking important strides toward our goal of being a leading provider of space infrastructure services that will enable the new space economy. Momentus placed five additional satellites in orbit during the quarter, successfully completed assembly and test of our next generation Orbital Service Vehicle (OSV), Vigoride 5, for launch on the SpaceX Transporter-6 mission targeted for next month, and advanced development of key technologies, such as our innovative and environmentally-friendly Microwave Electrothermal Thruster (MET) that uses water as a propellant.”
“We’re excited to be supporting some truly innovative work that will advance the technology boundaries in space. Next month, we are planning for Vigoride 5 to begin a several month mission that includes a hosted payload from CalTech that aims to demonstrate the ability to collect solar energy in space and transmit it to Earth. Their aim is to provide a new ground-breaking and environmentally-friendly way to meet energy needs on Earth.”
“Momentus is also thrilled to have signed a contract modification with NASA to transport two cube satellites that will perform cutting-edge research on weather events in space. This marks a big milestone in our efforts to grow into the Government market, which is an area we are prioritizing and see substantial opportunities for further growth.”
Third Quarter 2022 Business Highlights:
The Company’s Vigoride 3 Orbital Service Vehicle (OSV) deployed five customer satellites during the third quarter of 2022, bringing the cumulative number of customer satellite deployments from Vigoride 3 to seven and the total number of Momentus customer satellites deployed from all platforms to eight.
Applied lessons learned from the inaugural Vigoride mission to the next generation Vigoride 5 OSV in preparation for its planned launch on the SpaceX Transporter-6 mission, which is targeted for December 2022.
Conducted an expanded ground-testing campaign on Vigoride 5 and its component systems, including simulated zero-gravity deployment testing of the solar array that will power Vigoride 5, and ground hot fire testing of Vigoride 5’s next-generation Microwave Electrothermal Thruster (MET) propulsion module.
Completed ground vibration testing of the complete Vigoride 5 OSV to simulate the environment that it will experience on the SpaceX Falcon 9 launch vehicle. Subsequent to the close of the third quarter, Momentus completed thermal vacuum testing of Vigoride 5, which simulates the environment that it will encounter in space and concludes the overall Vigoride 5 environmental testing campaign.
Subsequent to the close of the third quarter, integrated customer satellites onto Vigoride 5, completed its Flight Readiness Review and are preparing to ship the vehicle to its launch site in Cape Canaveral, FL.
Signed a contract with a new commercial customer OHB LuxSpace to conduct a hosted payload mission.
Signed a contract modification with NASA’s Kennedy Space Center for transportation of two satellites to custom orbits. This mission highlights the unique capabilities of Momentus' OSV to transport a customer



satellite from the launch vehicle's standard drop-off orbit to its desired custom orbit. The NASA mission will perform cutting-edge research on space weather and Momentus is proud to provide the custom capabilities needed to support this work.
Signed a Memorandum of Understanding with Sidus Space, under which Momentus will collaborate and provide transportation and payload-hosting services for its Lizziesat satellites.
Put in place the framework for future capital raising efforts by filing an S-3 Universal Shelf Registration statement with a ceiling of $200M and launched a three-year, $50M At-The-Market Equity program.

Forward-Looking Statements
This press release contains certain statements which may constitute “forward-looking statements” within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include, but are not limited to, statements regarding Momentus or its management team’s expectations, hopes, beliefs, intentions or strategies regarding the future, projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, and are not guarantees of future performance. The words “may,” “will,” “anticipate,” “believe,” “expect,” “continue,” “could,” “estimate,” “future,” “expect,” “intends,” “may,” “might,” “plan,” “possible,” “potential,” “aim,” “strive,” “predict,” “project,” “should,” “would” and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking.
Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on our current beliefs, expectations and assumptions regarding the future of our business, future plans and strategies, projections, anticipated events and trends, the economy and other future conditions.
Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of Momentus’ control. Many factors could cause actual future events to differ materially from the forward-looking statements in this press release, including but not limited to: the ability of the Company to obtain licenses and government approvals for its missions, which are essential to its operations; the ability of the Company to effectively market and sell satellite transport services and planned in-orbit services; the ability of the Company to protect its intellectual property and trade secrets; the development of markets for satellite transport and in-orbit services; the ability of the Company to develop, test and validate its technology, including its water plasma propulsion technology; delays or impediments that the Company may face in the development, manufacture and deployment of next generation satellite transport systems; the ability of the Company to convert backlog or inbound inquiries into revenue; changes in applicable laws or regulations and extensive and evolving government regulations that impact operations and business, including export control license requirements; the ability to attract or maintain a qualified workforce with the required security clearances and requisite skills; product service or product or launch failures or delays that could lead customers to use competitors’ services; investigations, claims, disputes, enforcement actions, litigation and/or other regulatory or legal proceedings; the effects of the COVID-19 pandemic on the Company’s business; the Company’s ability to comply with the terms of its National Security Agreement and any related compliance measures instituted by the director who was approved by the CFIUS Monitoring Agencies (the “Security Director”); the possibility that the Company may be adversely affected by other economic, business, and/or competitive factors; and/or other risks and uncertainties. These are only some of the factors that may affect the forward-looking



statements contained in this press release. For a discussion identifying additional important factors that could cause actual results to differ materially from those anticipated in the forward-looking statements, see the company’s filings with the U.S. Securities and Exchange Commission including, but not limited to, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 and subsequent quarterly reports on Form 10-Q. The company’s filings may be accessed through the Investor Relations page of its website, investors.momentus.space, or through the website maintained by the SEC at www.sec.gov. Forward-looking statements speak only as of the date they are made.

2 - The reduction of cost of revenue represents the reversal of a contingency recorded during the prior year for loss contracts related to free slots on future missions. During the prior three months ended September 30, 2021, the Company signed amendments or terminations with those customers such that the services will no longer be free of charge. The reversed contingency was offset by costs incurred related to one of the cancelled contracts.
3 - Other expenses during the three months ended September 30, 2021 were due to the transaction costs allocated to the liability-classified warrant assumed in connection with the Business Combination.

Reclassifications
Certain reclassifications have been made to the prior year’s financial statements to conform to the current year’s presentation. None of the reclassifications have changed the total assets, liabilities, shareholders’ deficit, income, expenses or net losses previously reported.
Use of Non-GAAP Financial Measures (unaudited)
This press release references certain non-GAAP financial measures, including adjusted EBITDA, non-GAAP selling, general, and administrative expense and non-GAAP research and development expense. The Company defines adjusted EBITDA as earnings before interest expense, taxes, depreciation and amortization, stock-based compensation, and certain other items the Company believes are not indicative of its core operating performance. The Company defines non-GAAP selling, general, and administrative expenses and research and development expenses as those respective GAAP amounts, excluding stock-based compensation and non-recurring items not indicative of core operating performance None of these non-GAAP financial measures is a substitute for or superior to measures of financial performance prepared in accordance with generally accepted accounting principles in the United States (GAAP) and should not be considered as an alternative to any other performance measures derived in accordance with GAAP.
The Company believes that presenting these non-GAAP financial measures provides useful supplemental information to investors about the Company that is helpful in understanding and evaluating its operating results, enhancing the overall understanding of its past performance and future prospects, and allowing for greater transparency with respect to key financial metrics used by its management in financial and operational-decision making. However, there are a number of limitations related to the use of non-GAAP measures and their nearest GAAP equivalents. For example, other companies may calculate non-GAAP measures differently, or may use other measures to calculate their financial performance, and therefore any non-GAAP measures the Company uses may not be directly comparable to similarly titled measures of other companies.
Quarterly adjusted EBITDA
A reconciliation of adjusted EBITDA to net loss for the three months ended September 30, 2022, September 30, 2021, and June 30, 2022, is set forth below:

Many factors could cause actual future events to differ materially from the forward-looking statements in this presentation, including but not limited to risks related to obtaining licenses and government approvals for our missions; delays or impediments in vehicle development, manufacture, test and deployment; the harsh and unpredictable environment of space in which our products operate; increased competition in our industry due in part to rapid technological development; delays or impediments in the development, manufacture and deployment of our vehicles; failure of our vehicles and components to operate as intended either due to error in design in production or through no fault of our own; launch schedule disruptions; supply chain disruptions; product delays or failures; design and engineering flaws; launch failures or other events that force us to cancel or reschedule launches; our ability to convert backlog or inbound inquiries into revenue; investigations, claims, disputes, enforcement actions, litigation and/or other regulatory or legal proceedings; the effects of the COVID-19 pandemic on our business; and the factors, risks and uncertainties. These are only some of the factors that may affect the forward-looking statements contained in this presentation. For a discussion identifying additional important factors that could cause actual results to differ materially from those anticipated in the forward-looking statements, see the company’s filings with the U.S. Securities and Exchange Commission including, but not limited to, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Risk Factors” in the company’s Annual Report on Form 10-K for the year ended Dec. 31, 2021 and subsequent quarterly reports on Form 10-Q. The company’s filings may be accessed through the Investor Relations page of its website, investor.momentus.space, or through the website maintained by the SEC at www.sec.gov. Forward-looking statements speak only as of the date they are made. There can be no assurance that we will achieve the plans, intentions or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our forward-looking statements. Moreover, it is not possible for our management to predict all risks or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. You should read this presentation with the understanding that our actual results may be materially different from the plans, intentions and expectations disclosed in the forward-looking statements we make. Readers are cautioned not to put undue reliance on forward-looking statements, and, except as required by law, the Company assumes no obligation and does not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise. The technology underlying our anticipated service offerings is still in the process of being developed, and has not been fully tested or validated in space. Our ability to execute on our business plan is dependent on the successful development and commercialization of our technologies. Development of space technologies is extremely complex, time consuming, and expensive, and there can be no assurance that our predicted theoretical and ground-based results will translate into operational space vehicles that operate within the parameters we expect, or at all. Use of Non-GAAP Financial Measures This presentation references certain non-GAAP financial measures, including adjusted EBITDA, non-GAAP selling, general, and administrative expense and non-GAAP research and development expense. Momentus defines adjusted EBITDA as earnings before interest expense, taxes, depreciation and amortization, stock-based compensation, and certain other items Momentus believes are not indicative of its core operating performance. Momentus defines non-GAAP selling, general, and administrative expenses and research and development expenses as those respective GAAP amounts, excluding stock-based compensation and non- recurring items not indicative of core operating performance None of these non-GAAP financial measures is a substitute for or superior to measures of financial performance prepared in accordance with generally accepted accounting principles in the United States (GAAP) and should not be considered as an alternative to any other performance measures derived in accordance with GAAP. Momentus believes that presenting these non-GAAP financial measures provides useful supplemental information to investors about Momentus that is helpful in understanding and evaluating its operating results, enhancing the overall understanding of its past performance and future prospects, and allowing for greater transparency with respect to key financial metrics used by its management in financial and operational-decision making. However, there are a number of limitations related to the use of non-GAAP measures and their nearest GAAP equivalents. For example, other companies may calculate non-GAAP measures differently, or may use other measures to calculate their financial performance, and therefore any non-GAAP measures Momentus uses may not be directly comparable to similarly titled measures of other companies. 2
