**CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS**

This Annual Report on Form 10-K (this "Form 10-K"), including, without limitation, statements under the headings "Management's Discussion and Analysis of Financial Condition and Results of Operations," includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, (the "Securities Act") and Section 21E of the Securities Exchange Act of 1934, as amended, (the "Exchange Act"). Generally, statements that are not historical facts, including statements concerning Momentus Inc.'s (the "Company," "Momentus," "we," "us," or "our") possible or assumed future actions, business strategies, events, or results of operations, are forward-looking statements. These forward-looking statements can be identified by the use of forward-looking terminology, including the words "believes," "estimates," "anticipates," "expects," "intends," "plans," "may," "will," "potential," "projects," "predicts," "continue," or "should," or, in each case, their negative or other variations or comparable terminology, but the absence of these words does not mean that a statement is not forward-looking. There can be no assurance that actual results will not materially differ from expectations.

The forward-looking statements contained in this Annual Report on Form 10-K are based on our current expectations and beliefs concerning future developments and their potential effects on us. Future developments affecting us may not be those that we have anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond our control) and other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. These risks and uncertainties include, without limitation, the ability of the Company to raise additional capital to finance its longer-term business plan; the ability of the Company to obtain licenses and government approvals for its missions,

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

which are essential to its operations; the ability of the Company to effectively market and sell satellites and satellite components; the ability to market and sell 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 small satellites and satellite transport and in-orbit services; the ability of the Company to develop, test and validate its technology, including its water plasma propulsion technology and Tape Spring Solar Array; 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; level of 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 possibility that the Company may be adversely affected by other economic, business, and/or competitive factors; and/or other risks and uncertainties described under Item 1A: "*Risk Factors*." Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. We undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise, except as may be required under applicable securities laws. These risks and others described under Item 1A: "*Risk Factors*" may not be exhaustive.

By their nature, forward-looking statements involve risks and uncertainties because they relate to events and depend on circumstances that may or may not occur in the future. We caution you that forward-looking statements are not guarantees of future performance and that our actual results of operations, financial condition and liquidity, and developments in the industry in which we operate may differ materially from those made in or suggested by the forward-looking statements contained in this Annual Report on Form 10-K. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements. In addition, even if our results or operations, financial condition and liquidity, and developments in the industry in which we operate are consistent with the forward-looking statements contained in this Annual Report on Form 10-K, those results or developments may not be indicative of results or developments in subsequent periods.

**Summary of Risk Factors**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We may not be able to convert our customer contracts into revenue.

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our business involves significant risks and uncertainties that may not be covered by insurance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If our spacecraft fail to operate as intended, it could have a material adverse effect on our business, financial condition, and results of operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We may experience warranty claims for failures, schedule delays or other problems with existing or new products.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We are highly dependent on our senior management team and other highly skilled personnel.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** We are subject to stringent U.S. export and import control laws and regulations. Our failure to comply with these laws and regulations could have a material adverse effect on our business, financial condition and results of operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

**Risks Related to Ownership of our Class A Common Stock**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The market price of our Class A common stock and warrants may be volatile, which could cause the value of your investment to decline.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Future sales of shares by Company officers, directors, other insiders or existing stockholders adversely affect the market price of our Class A common stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our charter documents and Delaware law could prevent a takeover that stockholders consider favorable and could also reduce the market price of the Class A common stock.

We provide or plan to provide satellites, satellite buses, solar arrays, and other satellite components. Our satellites and satellite technologies offer competitive advantages to customers such as greater payload capability, significant on-orbit power, flexibility of design and the ability to accommodate a range of sensors, communications equipment, and other space instruments, low cost, and speed of delivery.

We are developing an innovative Tape Spring Solar Array ("TASSA") that has the potential to produce power at substantially lower cost than competing solar arrays. TASSA also has important advantages in its ability to be deployed and retracted to protect the array from in-space collisions with debris and to easily maneuver the satellite to different locations or adjust its characteristics.

Over the past several years, Momentus has developed other innovative technologies, such as our Microwave Electrothermal Thruster ("MET") that uses water as a propellant, designed to efficiently accomplish missions such as transportation of customer payloads and small satellites to custom orbits. The MET's water propellant is safe, environmentally-friendly, and easy to transport and handle, in contrast to the highly-toxic and difficult to handle propellants commonly used in the space industry. The MET has high specific impulse, or ISP, which is a measure of efficiency, making it well-suited for transportation missions with significantly higher thrust than missions more suitable for low thrust electric propulsion. The MET has been successfully demonstrated on orbit and we have matured this technology to Technology Readiness Level 9, the highest level, with hundreds of successful firings in space during our missions. We have designed our satellite buses and Orbital Service Vehicles to use this innovative technology, while also implementing a modular design that enables Momentus to incorporate high-thrust chemical thrusters or electric thrusters instead of the MET for missions with different requirements.

We provide or plan to provide services, including "last mile" satellite transportation, payload-hosting, on-orbit satellite refueling, on-orbit inspection, on-orbit satellite maintenance, de-orbiting, debris removal, and other satellite-to-satellite service offerings. We believe our planned service offerings will increase deployment options for satellite operators and lower their operating costs relative to traditional approaches while also minimizing environmental impact when utilizing our MET with water as a propellant.

We plan to provide these services with Orbital Service Vehicles ("OSVs") that we design and manufacture. While we plan to eventually operate a family of progressively larger and more capable OSVs, we are currently focused on

Vigoride, which was originally designed to operate in low-Earth orbit ("LEO"), but is undergoing enhancements designed to allow it to operate in Geostationary-Earth Orbit ("GEO"), Lunar, and Deep Space orbits.

We believe that Vigoride has the ability to deliver fast, versatile, and cost-effective transportation and infrastructure services to our customers. We conducted our inaugural test and demonstration mission with Vigoride in 2022. Momentus has launched four missions to date, deployed 17 customer satellites, and provided hosted payload services. Three of these missions involved operation of the Vigoride OSV in orbit. During these three Vigoride missions, the system and technology were tested repeatedly. Improvements based on lessons learned during these missions were rapidly incorporated. As a result of these three missions, the Vigoride OSV has been successfully demonstrated in space and accumulated significant flight heritage.

Our transportation service offering focuses on delivering our customers' satellites to precision orbits. To accomplish this, we partner with leading launch service providers, such as SpaceX, to "ride share" our customer's satellites from Earth to space on a midsized or large rocket. Customer satellites can also be carried aboard small launch vehicles for dedicated missions. Our OSVs would then provide "last mile" transportation services from the rocket's drop-off orbit to a custom orbit of the satellite operator's choosing. We believe this "hub-and-spoke" model has the potential to expand our customers' deployment options relative to what they would be able to achieve with ride share launch alone, while reducing their costs relative to what they could achieve with a dedicated small launch vehicle.

Our OSVs are currently expendable, meaning they are used to perform services before they de-orbit themselves upon completion of their mission. However, our goal is to eventually make our OSVs reusable, or capable of remaining in space to conduct follow-on missions, which has the potential to lower our cost of delivering services to our customers. To achieve reusability, we need to develop additional technologies that will allow our vehicles to locate and navigate to customer satellites in space, physically connect to them, and perform a variety of robotic operations including fluid transfer. The first of these technologies is related to Rendezvous and Proximity Operations ("RPO") which is the ability for the OSV to locate and maneuver to another object in space.

In 2025, the U.S. Air Force Research Labs SpaceWERX organization—which is the innovation arm of the U.S. Space Force—awarded Momentus a Direct to Phase II Small Business Innovation Research ("SBIR") contract. The award supports the in-space flight demonstration of a novel, low-cost multi-spectral sensor suite for RPO, scheduled for early 2026.

We are also offering variants of our Vigoride OSV to government and commercial customers as a traditional bus manufacturer and satellite prime contractor. Vigoride, and its variants, M-500 and M-1000, are being offered to support missions such as communication, sensing and tracking of missiles, positioning, navigation, and timing ("PNT") as well as payload technology demonstrations.

Momentus offers or plans to offer production and operation of small satellites to meet a range of defense, government, and commercial needs such as communications, tracking of missiles, remote sensing, and space domain awareness. There is a growing need for such capabilities for defense, government, and commercial customers.

Momentus is offering high-volume production of buses, based on Vigoride's technologies, for hosted payloads by integrating customer's unique payloads for a variety of missions and for customer-owned satellites for use in constellations. A hosted payload is a module attached to a satellite that can be operated independently from the main spacecraft but which shares the satellite's power supply and communications equipment. Hosted payloads are often used by commercial and government customers seeking to operate or test a capability for uses such as communications and sensing in orbit without having to pay the cost of building and launching an entire satellite. Using a hosted payload on a commercial satellite can reduce both the expense and time required to get communications and other technologies into space.

Our Vigoride OSVs are intended to provide safe, affordable, reliable, and regular in-space services to our customers, including space transportation, payload hosting, and in-orbit servicing. We designed our Vigoride vehicle to deliver small customer payloads anywhere in LEO. However, we also plan to design and produce larger vehicles and satellite buses to carry larger payloads to more distant orbits such as GEO.

We currently plan to offer the following infrastructure services to the space economy:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Satellites and Constellation Bus:** Momentus offers or plans to offer production and operation of small satellites to meet a range of defense, government, and commercial needs such as communications, tracking of missiles, remote sensing, and space domain awareness. Technologies used to support the Hosted Payload market are directly applicable to offering customer-owned satellites for use in constellations.

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Satellite Technologies:** Momentus is developing and plans to offer satellite technologies such as our Tape Spring Solar Array, 3D printed propulsion tanks, and other components used on the Vigoride OSV. These technologies and components have been flown in space, or are scheduled to be flown in space, and offer important competitive advantages such as lower cost and flexibility to meet the needs of owners and operators of satellites.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Space Transportation:** Momentus offers a transportation service to deliver customers' satellites to precision orbits. Under this model, our customers would deliver their payload to us a few months prior to launch for integration onto our vehicle. Once we have integrated our customers' payloads, we would then ship our vehicle, holding the customer payload, to the launch site, where it would be integrated onto the launch vehicle. The launch vehicle would then transport our vehicle to the drop-off orbit. After separation from the launch vehicle, our OSV would transport our customers' payloads to their chosen final orbit.

We believe our transportation service has the potential to expand our customers' deployment options relative to what they could achieve with ride share launch alone, while reducing their costs relative to what they could achieve with a dedicated small launch vehicle.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Hosted Payload:** There are a broad range of payloads, satellite components, and other space technologies, that customers want to operate, test, or validate in space. During development of a satellite component or other system, testing and validation of performance are important, particularly in the harsh environment of space. In other cases, customers wish to operate technologies such as solar collection and energy transmission systems in space without the expense of developing a full system that includes the satellite bus hosting these instruments. Momentus' hosted payload service allows customers to operate, test, and validate the performance of the technology or system in space at lower cost and less complexity. Momentus' service offers the ability to manage the integration and operation of these payloads in space. Additionally, Momentus is able to obtain necessary government licenses and manage the integration of these hosted payloads onto our OSV.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **In-Orbit Servicing:** As the number of satellites in space increases, so does their need to be serviced. We are actively developing and testing Momentus' vehicles to be capable of performing in-orbit servicing. We plan to equip future vehicles with robotic arms and an ability to maneuver in close proximity to other spacecraft and grapple, dock, or berth with them. We believe these capabilities could allow us to offer a suite of different in-orbit services, such as inspection, refueling, life extension, re-positioning, salvage missions, maintenance and repair, and de-orbiting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Satellite Bus:** Technologies used to support the hosted payload market are directly applicable to offering customer-owned satellite buses for use in constellations. Momentus is offering high-volume production of low-cost buses, based on Vigoride's technologies, and integrating customers' unique payloads for a variety of missions ranging from communications to Earth Observation. We introduced variants of Vigoride tailored specifically for constellation applications as M-500 and M-1000 in August 2023.

**Industry and Competitive Advantage Overview**

Our services are made possible by the space industry's rapid technological developments over the past two decades, driven predominantly by significant decreases in launch costs, as well as the advent of smaller, lower-cost satellites. This convergence of trends has led to increased access to space, new market entrants and accelerated growth in the number of commercial satellites being placed into orbit.

We anticipate considerable growth over the coming years in demand for small satellites and satellite buses. We also anticipate that the space transportation segment will grow as companies continue to seek versatile and low-cost ways to deliver single satellites to specific orbits or deploy their satellite constellations. We anticipate that the need for small satellite and satellite bus transportation to LEO, GEO, and Cis-Lunar orbits will continue to drive overall demand growth for space transportation services in the short-term as technology advancements continue to make space more accessible to new market entrants. We also believe that over the next decade, new space-based businesses may emerge, for example the generation of solar energy in space, space manufacturing or space data processing. The advent of these new business models could substantially increase demand for space transportation and other space infrastructure services.

Beyond transportation, we anticipate that growth of the satellite constellations market may drive demand for our satellites, satellites buses, and technologies like solar arrays, hosted payload, on-orbit satellite refueling, on-orbit inspection, on-orbit satellite maintenance, de-orbiting, debris removal, and other satellite-to-satellite service offerings, if we are successful in executing on our business plan, including fully developing and validating our

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

technology in space. Satellite constellations have relatively low lifespans and, in our view, will require maintenance, de-orbiting, and other general servicing with higher frequency.

We believe our ability to compete successfully as a commercial provider of space transportation, communication, and infrastructure services will depend on several factors including our ability to fully develop, test and validate our technology in space, our ability to establish and maintain a lead in technological advancements, the price of our offerings, customer confidence in the reliability of our offerings, and the frequency and availability of our offerings. If we are unable to fully develop, test and validate our technologies, we may be unable to execute on our business plan and realize the following competitive advantages. We believe that our team's collective expertise, coupled with the following strengths, will allow us to build our business and compete successfully.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Focus on leveraging common technologies through modular vehicles:** Momentus is applying technologies developed on Vigoride to offer both in-space services and traditional satellite production and bus manufacturing to customers. We believe that this approach will allow us to compete across multiple markets without dramatically increasing our development costs. This approach also allows us to offer bundled services to constellation operators and generate differentiated offerings blending traditional bus capabilities with next-generational service-oriented features and capabilities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Unique technology with patents pending:** Over the past several years, we have worked on developing our patent-pending water plasma propulsion technology that we have demonstrated repeatedly in space, and we have designed our vehicles and services to incorporate this technology. We have also developed technologies related to space infrastructure system architectures and low-cost solar arrays. We are in the process of creating a patent portfolio and, as of December 31, 2025, we had eight issued patents, four non-U.S. issued patents, and applications for one additional patent family relating to our water plasma propulsion and other technologies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Compatibility across launch providers:** We have designed and plan to continue to design our future vehicles to be compatible with most launch vehicles. We believe this will give our customers flexibility around the timing and availability of launches and ensure a competitive market for our launch providers. As more rocket operators emerge, we will work to continue to actively incorporate compatibility to increase customer accessibility.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Relationships with launch providers:** We have relationships with several launch providers including SpaceX, Relativity Space, Blue Origin, United Launch Alliance (ULA), Rocket Factory Augsburg (RFA), and several other rocket providers. We believe our relationship and launch agreement with SpaceX will help us maximize the flexibility, economics, and optionality we can offer our customers. Additionally, as an aggregator of payloads, we believe we will be able to continue to service customers from around the world who might not otherwise have access to launch options.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Experienced management team:** Many of our management team members have experience in large organizations, including the U.S. Department of Defense, Raytheon, Lockheed Martin, Maxar, ULA, and Northrop Grumman, among others. Our efficient vertical integration allows for significant cooperation and interactivity between teams.

**Regulatory**

See "*Risk Factors*" for risks and uncertainties related to regulatory requirements.

*Federal Communications Commission*

The regulations, policies, and guidance issued by the Federal Communications Commission (the "FCC") apply to the operation of our satellites and vehicles. When we communicate with our satellites and vehicles using any part of the electromagnetic spectrum, we are operating a space station to which FCC regulations apply. Operators of regulated space stations are required to hold and maintain compliance with proper licenses, and the specific conditions thereof throughout the duration of any given mission. Operators may also seek licenses in other jurisdictions in accordance with multilateral agreements governing the use of the spectrum, and such licenses would generally be accorded equal treatment by the United States. For our initial flight in May 2022 the FCC granted us a Special Temporary Authorization ("STA"), which was modified and extended for five 30-day periods at our request. Following the enactment of a new set of FCC licensing guidelines for small satellites and related systems that applied to Momentus spacecraft, we applied for and in November 2022 were granted an FCC license for the Vigoride 5 mission. We applied for and in February 2023 were granted an FCC license for the Vigoride 6 mission. Momentus applied for an FCC license for the Vigoride 7 mission planned for the first half of 2026, which was granted by the FCC on January 30, 2026. The FCC continues to consider additional rules which, among other things, could change the operational, technical, and financial requirements for Momentus operations. If these proposed rules become final, they could change system design and financial costs in order to comply with or secure new Momentus spectrum licensure.

*National Oceanic and Atmospheric Administration*

Momentus transport vehicles will operate with space-qualified photographic equipment installed. While primarily intended to function as mission assurance tools, these cameras will be capable of capturing incidental Earth imagery while in orbit. As such, we believed these cameras to be subject to the licensing requirements and regulations of the National Oceanic and Atmosphere Administration's ("NOAA") Commercial Report Sensing Regulatory Affairs ("CRSRA") office. Until February 2023 we held a license grant from CRSRA authorizing the first ten Vigoride missions. As a consequence of a NOAA interpretation of the licensing regulations and at the suggestion of NOAA, we surrendered that license in February 2023. For the Vigoride 7 mission planned for the first half of 2026, Momentus requested a license associated with a RPO that is expected to occur during this mission. On February 13, 2026, NOAA issued a temporary license. Momentus plans to complete additional submissions to NOAA as part of the licensing process with the aim of obtaining a permanent license prior to the RPO Demonstration. For future missions we will apply for any required NOAA authorizations on a case-by-case basis.

*Federal Aviation Administration*

As a participant in launch activities, we are indirectly subject to the license requirements of the Federal Aviation Administration's (the "FAA") Office of Commercial Space Transportation (the "AST"). The FAA regulates the airspace of the United States, through which launch vehicles must fly during launch to orbit. The AST office predominantly processes launch license requests submitted by launch vehicle operators, which include information on the constituent payloads flying on any given mission. As a result, reviews of our payloads by the AST occur during, for example, the processing of a SpaceX launch license.

*International Traffic in Arms Regulations and Export Controls*

Our orbital infrastructure business is subject to, and we must comply with, stringent U.S. import and export control laws, including the International Traffic in Arms Regulations (the "ITAR") of the U.S. Department of State, and the Export Administration Regulations (the "EAR") of the Bureau of Industry and Security of the U.S. Department of Commerce. The ITAR generally restricts the export of hardware, software, technical data, and services that have defense or strategic applications. The EAR similarly regulates the export of hardware, software, and technology that has commercial or "dual-use" applications (i.e., both military and commercial applications) or that have less sensitive military or space-related applications that are not subject to the ITAR. The regulations exist to advance the national security and foreign policy interests of the United States.

The U.S. government agencies responsible for administering the ITAR and the EAR have significant discretion in the interpretation and enforcement of these regulations. The agencies also have significant discretion in approving, denying, or conditioning authorizations to engage in controlled activities. Such decisions are influenced by the U.S. government's commitments to multilateral export control regimes, particularly the Missile Technology Control Regime concerning the spaceflight business.

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

Many different types of internal controls and measures are required to ensure compliance with such export control rules. In particular, we are required to maintain registration under the ITAR; determine the proper licensing jurisdiction and classification of products, software, and technology; and obtain licenses or other forms of U.S. government authorizations to engage in activities, including the performance by foreign persons, related to and who support our spaceflight business. Under the ITAR and the EAR, we must receive permission to release controlled data to foreign persons or physically ship controlled hardware abroad.

See "*Risk Factors—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 operation." The inability to secure and maintain other necessary export authorizations could negatively impact our ability to compete successfully or to operate our spaceflight business as planned.

Failure to comply with export control laws and regulations could expose us to civil or criminal penalties, fines, investigations, more onerous compliance requirements, loss of export privileges, debarment from government contracts, or limitations on our ability to enter into contracts with the U.S. government. In addition, any changes in export control regulations or U.S. government licensing policy, such as that necessary to implement U.S. government commitments to multilateral control regimes, may restrict our operations.

*Interagency Review*

Approval of the licenses described above may be subject to interagency reviews that allow multiple government agencies—the U.S. Department of Commerce, U.S. Department of Defense, U.S. Department of State, National Aeronautics and Space Administration ("NASA"), and others—to examine the respective applications from their individual perspectives, including safety, operational, national security, and foreign policy and international obligations implications, as well as review of foreign ownership. No assurance can be given that we will obtain the licenses described above in this section for our future missions. Even though Momentus entered into and implemented the National Security Agreement ("NSA") which is described below and which the U.S. government subsequently ended, there is no guarantee that the FAA and other U.S. government agencies will continue to grant the necessary authorizations.

**Human Capital**

People are our most important asset. Since its inception, Momentus has sought to recruit creative, positive people with a diverse set of business capabilities to play an integral role in building our company. As we move into the next stage of our evolution, we are focused on optimizing the human capital resources we have available and are building the infrastructure necessary to support our workforce and promote communication, respect, and diversity among our team. Our Human Resources and Talent Acquisition department continues to actively recruit new talent. Many of our employees bring significant experience from prior positions working for leading defense primes, satellite manufacturers, other commercial and military aerospace companies, and government agencies. As of March 15, 2026, the Company had 35 employees.

**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.***

Momentus had cash and cash equivalents of $12.8 million as of December 31, 2025. We need to raise additional capital to continue our operations and execute on our business plan. Our ability to raise additional capital is subject to a number of risks and uncertainties outside of our control, and there can be no assurance that we will be successful at raising capital when we need it, on acceptable terms, or at all.

To raise additional funding, we may need to sell equity or debt securities in one or more transactions at prices and on terms that are determined from time to time. As an incentive to investors, we may also issue warrants, including pre-funded warrants, as part of these transactions. Our current stockholders will be diluted by the issuance of equity securities or securities convertible into equity securities in connection with these transactions, and the terms of any such transactions may not be favorable to the Company. Any debt financing, if available, may also involve restrictive covenants that could reduce our operational flexibility or profitability.

If we cannot raise funds on acceptable terms, or at all, we may not be able to grow our business, respond to competitive pressures or continue our operations.

***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 incurred net losses of $30.5 million and $34.9 million for the years ended December 31, 2025 and 2024, respectively. There is a risk that we may not achieve profitability when expected, or at all, and even if we do, we may not be able to maintain or increase profitability.

Any failure to increase our revenue sufficiently to keep pace with our investments and other expenses, or any future negative cash flow or losses resulting from the operation of our business, could have a material adverse effect on our business, financial condition, and results of operations.

***We may not be able to continue as a going concern.***

The accompanying financial statements have been prepared on a going concern basis of accounting which assumes that we will continue as a going concern, and do not reflect any adjustments that might result if the Company is unable to continue as a going concern. The Company's ability to continue as a going concern is dependent on the Company's ability to generate revenues and raise capital. To date, the Company has not generated sufficient revenues to provide cash flows that enable the Company to finance its operations.

Management has concluded that its mitigation plans alleviate the substantial doubt about the Company's ability to continue as a going concern for at least one year from the date these consolidated financial statements are issued. See Note 1, Nature of Operations, for a discussion of management's mitigation plans.

If management is unable to implement its mitigation plans or otherwise find sources of additional funding, the Company 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.***

The success of our business depends on our ability to successfully and regularly deliver customer satellites and payloads to custom orbits. Our initial mission, Vigoride 3, in May 2022 was a hybrid commercial-demonstration mission on which our vehicle was scheduled to deliver paying customers' satellites into orbit for the first time. We used a third-party deployer from a partner company to place our first customer satellite in orbit. Our Vigoride 3 spacecraft reached low-Earth orbit and was able to deploy two out of nine customer satellites, but certain anomalies relating primarily to its power systems limited our ability to communicate with and control the vehicle. After that time, the Vigoride 3 deployed five additional customer satellites, but we have been unable to confirm the deployment of the remaining two customer satellites. These issues also prevented Vigoride 3 from performing orbit change maneuvers and technology demonstrations that were part of our program to validate our technology in space and to demonstrate end-to-end in-space transfer and service operations.

We used the Vigoride 5 and Vigoride 6 missions to conduct on-orbit functional testing for the MET and other system elements which were used to assess the performance of the individual components and our overall system. Like the ground test campaigns we conduct, on-orbit tests are designed to address key requirements for thrust, specific impulse, firing duration, lifetime and other performance parameters which help Momentus determine whether the MET and other system elements are performing in accordance with our expectations. Doing so repeatedly, both on the ground and on orbit, enabled Momentus to mature the MET to Technology Readiness Level 9, the highest level.

There are inherent risks involved in the initial use of hardware and complex systems in space given the difficulties of replicating all aspects of the environment and stresses that the system will experience in space during ground-based testing in simulated environments.

While we conducted analysis of the root causes of all anomalies experienced during the three missions, there can be no assurance that we will not experience operational or process failures and other problems on future missions. Any failures, delays, or setbacks, including anomalies experienced in our current or future mission, could harm our reputation and have a material adverse effect on our business, financial condition, and results.

***Our business is subject to the policies, priorities, regulations, mandates and funding levels of governmental entities and may be negatively or positively impacted by any change thereto.***

We are subject to a wide variety of laws and regulations relating to various aspects of our business, including with respect to our orbital service vehicles, employment and labor, health care, tax, data privacy of the personal information we collect and process and data security of the operational and information technology we use, health and safety, and environmental issues. Laws and regulations at the foreign, federal, state, and local levels frequently change and are often interpreted in different ways, especially in relation to new and emerging industries, and we cannot always reasonably predict the impact from, or the ultimate cost of compliance with, current or future regulatory or administrative changes. While we monitor these developments and devote a significant amount of management's time and external resources towards compliance with these laws, regulations and guidelines, we cannot guarantee that these measures will be satisfactory to regulators or other third parties, such as our customers. Moreover, changes in law, the imposition of new or additional regulations or the enactment of any new or more stringent legislation that impacts our business could require us to change the way we operate and could have a material adverse effect on our sales, profitability, cash flows, and financial condition.

Failure to comply with these laws, such as with respect to obtaining and maintaining licenses, certificates, authorizations, and permits critical for the operation of our business, may result in civil penalties or private lawsuits, or the suspension or revocation of licenses, certificates, authorizations, or permits, which would prevent us from operating our business. For example, the operation and launch of our spacecraft in the United States require licenses and permits from the FCC, the FAA, the NOAA, as well as review by other agencies of the U.S. government, including the U.S. Department of Defense, U.S. Department of State, and NASA. Such license approvals may include an interagency review of safety, operational, national security, foreign policy implications, and international obligations, as well as a review of foreign ownership. Any delays in regulatory actions allowing us to conduct our commercial space operations could adversely affect our ability to operate our business and our financial results.

No assurance can be given that we will obtain FAA or FCC authorizations or other authorizations that may be necessary to our business in a timely manner. Moreover, there is no guarantee that the FCC, the FAA and other U.S. government agencies will grant the necessary authorizations to operate our spaceflight business as planned. If

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

we do not receive these approvals in a timely manner, our financial condition, results of operations, backlog and prospects will be materially adversely affected.

***We are dependent on the successful development of our satellite and related technology.***

Our current primary research and development objectives focus on the development of satellites, satellite buses, related satellite technologies such as solar arrays and our existing and future OSVs and related technology. If we do not complete development of these vehicles in our anticipated timeframes or at all, our ability to grow our business will be adversely affected. The successful development of our vehicles and related technology involves many uncertainties, some of which are beyond our control, including, but not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• timing in finalizing satellite and Orbital Service Vehicle design and specifications;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• successful completion of test programs and demonstration missions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether we will receive and the timing of receipt of licenses and government approvals that will allow us to fly our vehicles in space and gather valuable data that will assist in further development of our vehicles;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• meeting stated technological objectives and goals for the design on time, on budget and within target cost objectives;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to obtain additional applicable approvals, licenses or certifications from regulatory agencies and maintaining current approvals, licenses or certifications;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to secure slots on our launch providers' manifests;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• performance of our manufacturing facility despite risks that disrupt productions, such as natural disasters;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• performance of a limited number of suppliers for certain raw materials and supplied components and their willingness to do business with us;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• performance of our third-party contractors that support our research and development activities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to protect our intellectual property critical to the design and function of our transport vehicles and other technologies; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to continue funding and maintaining our research and development activities.

***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.***

The markets in which we operate are characterized by changing technology and evolving industry standards, and we may not be successful in identifying and marketing products and services that respond to rapid technological change, evolving technical standards and systems developed by others. Our competitors may develop technology that better meets the needs of our customers. If we do not continue to develop, manufacture, and market innovative technologies or applications that meet customers' requirements, sales may suffer, and our business may not continue to grow in line with historical rates or at all. If we are unable to achieve sustained growth, we may be unable to execute our business strategy, expand our business, or fund other liquidity needs, and our business prospects, financial condition and results of operations could be materially and adversely affected.

***We operate in highly competitive industries and in various jurisdictions across the world which may cause us to have to reduce our prices.***

Many of our competitors are larger and have substantially greater resources than we have. We may also face competition in the future from emerging low-cost competitors. Competition in the rocket launch, satellite and satellite component businesses is highly diverse, and while our competitors offer different products and services, there is often competition for contracts.

In addition, some of our foreign competitors currently benefit from, and others may benefit in the future from, protective measures by their home countries where governments are providing financial support, including significant investments in the development of new technologies. Government support of this nature greatly reduces the commercial risks associated with rocket launch, satellite and satellite component development activities for these competitors. This market environment may result in increased pressures on our pricing and other competitive factors.

***Momentus' limited operating history makes it difficult to evaluate its future prospects and the risks and challenges it may encounter.***

We have been focused on developing satellite technology and space transportation, communication, and infrastructure services since 2017. While we have operated since 2017, we have limited operating history in developing and commercializing these technologies and services, particularly at scale. This limited operating history makes it difficult to evaluate Momentus' future prospects and the risks and challenges we may encounter. Momentus faces now and expects to face in the future risks and challenges related to our ability to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• raise additional funding;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• forecast revenue and budget for and manage expenses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• attract new customers and retain existing customers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• effectively manage growth and business operations, including planning for and managing capital expenditures for current and future vehicles and services, and managing the supply chain and supplier relationships related to current and future vehicles and services;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• comply with existing and new or modified laws and regulations applicable to our business, including export control regulations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• anticipate and respond to macroeconomic changes and changes in the markets in which we operate;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• maintain and enhance the value of our reputation and brand;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• develop and protect intellectual property; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• integrate and retain talented people at all levels of our organization.

If Momentus fails to address the risks and challenges that we face, including those associated with the challenges listed above as well as those described elsewhere in this "*Risk Factors*" section, our business, financial condition, and results of operations could be adversely affected. Further, because Momentus has limited historical financial data and operates in a rapidly evolving market, any predictions about our future revenue and expenses may not be as accurate as they would be if we had a longer operating history or operated in a more developed market. Momentus has encountered in the past, and will encounter in the future, risks and uncertainties frequently experienced by companies with limited operating histories in rapidly changing industries. If Momentus' assumptions regarding these risks and uncertainties, which we use to plan and operate our business, are incorrect or change, or if we do not address these risks successfully, our results of operations could differ materially from our expectations and our business, financial condition, and results of operations could be adversely affected.

***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.***

The markets for satellite buses, orbital service vehicles and related in-space infrastructure services are emerging, difficult to quantify and subject to significant uncertainty. Our growth depends in part on the expansion of customer demand for these products and services, which may develop more slowly than we expect or not at all. Market adoption depends on factors beyond our control, including launch availability and cost, mission success, customer acceptance, government budgets and procurement activity, regulatory developments and the overall growth of the commercial space economy. In addition, customers may delay or reduce purchases while evaluating competing technologies, providers and business models, particularly with respect to orbital service vehicles and other newer in-space capabilities. If these markets fail to develop as we expect, our business, prospects, results of operations and financial condition could be materially adversely affected.

***We may not be able to convert our customer contracts into revenue.***

Our customer contracts are cancellable by customers for convenience. If a customer cancels a contract before it is required to pay the last deposit prior to launch, we may not receive all potential revenue from these orders, except for an initial non-refundable deposit which is typically due at the time the contract is signed. In certain situations, Momentus may decide to refund customer deposits, even though it is not contractually required, to maintain goodwill with customers.

***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.***

Our financial performance is dependent on our ability to generate a sustainable order rate for our services. This can be challenging and may fluctuate on an annual basis as the number of contracts awarded varies. If we are unable to win new awards or execute existing contracts as expected, our business, results of operations, and financial position could be further adversely affected.

***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.***

Our growth is dependent on the growth in the sales of services provided by our customers, our customers' ability to anticipate market trends, and our ability to anticipate changes in the businesses of our customers and to successfully identify and enter new markets. If we fail to anticipate such changes in demand, our business, results of operations, and financial position could be adversely affected.

We have previously experienced, and may experience in the future, delays or other complications in the design, manufacture and commercialization of new rocket launch services, mission services, satellites, satellite components and related technology. If we fail to develop and successfully commercialize new technologies, if we fail to develop such technologies before our competitors, or if such technologies fail to perform as expected, or are inferior to those of our competitors, our business, financial condition, and results of operations could be materially and adversely impacted.

***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.***

Although there have been and will continue to be technological advances in spaceflight, it is still an activity with inherent risk. Explosions and other accidents on launch or during flight have occurred and will likely occur in the future. If such incidents should occur, we will likely experience a total loss of our vehicle and our customers' payloads. The total or partial loss of one or more vehicles or customer payloads could have a material adverse effect on our results of operations and financial condition. For some missions, we can elect to buy launch insurance, which can reduce our monetary losses from the launch failure, but it may not cover all losses associated with launch failure and possible further losses incurred from the inability to test our technology from the result of such failure.

Depending on the circumstances and market conditions, launch insurance may be extremely expensive, and we cannot assure you that we will be able to acquire it on favorable terms, or at all.

***Our business involves significant risks and uncertainties that may not be covered by insurance.***

A significant portion of our business relates to designing, developing, and manufacturing advanced space technology products and services. New technologies may be untested or unproven. Failure of some of these products and services could result in extensive property damage. Accordingly, we may incur liabilities that are unique to our products and services.

The amount of insurance coverage that we maintain may not be adequate to cover all claims or liabilities. Existing coverage may be canceled while we remain exposed to the risk and it is not possible to obtain insurance to protect against all operational risks, natural hazards and liabilities.

We have insured against liability to third parties from launch activities as required by law to the extent that insurance was available on acceptable premiums and other terms. The insurance coverage for third-party damages may not be sufficient to cover the liability. In addition, this insurance will not protect us against our own losses, including to our launch support operations, complex, and satellites.

The price and availability of insurance fluctuate significantly. Insurance market conditions or factors outside our control, such as failure of launch vehicles and satellites, could cause premiums to be significantly higher than current estimates and could reduce amounts of available coverage. The cost of our insurance has been increasing and may continue to increase. Higher premiums on insurance policies will reduce our operating income by the amount of such increased premiums. If the terms of insurance policies become less favorable than those currently available, there may be limits on the amount of coverage that we can obtain, or we may not be able to obtain insurance at all.

In addition, even though we carry business interruption insurance policies, any business interruption losses could exceed the coverage available or be excluded from our insurance policies. Any disruption of our ability to operate

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

our business could result in a material decrease in our revenues or significant additional costs to replace, repair, or insure our assets, which could have a material adverse impact on our financial condition and results of operations.

Our customers and suppliers face similar threats. Customer or supplier proprietary, classified, or sensitive information stored on our networks is at risk. Assets, intellectual property and products in customer or supplier environments are also inherently at risk. We also have risk where we have access to customer and supplier networks and face risks of breach, disruption, or loss as well.

Satellites are subject to manufacturing and launch delays, damage, or destruction during pre-launch operations, launch failures and incorrect orbital placement, the occurrence of which can materially and adversely affect our operations.

Delays in the manufacturing of satellites, launch delays, damage, or destruction during pre-launch operations, launch failures or incorrect orbital placement could have a material adverse effect on our business, financial condition and results of operations. The loss of, or damage to, a satellite due to a launch failure could result in significant delays in anticipated revenue to be generated by that satellite. Any significant delay in the commencement of service of a satellite would delay or potentially permanently reduce the revenue anticipated to be generated by that satellite. In addition, if the loss of a satellite were to occur, we may not be able to accommodate affected customers with our other satellites until a replacement satellite is available, and we may not have on hand, or be able to obtain in a timely manner, the necessary funds to cover the cost of any necessary satellite replacement. Any launch delay, launch failure, underperformance, delay, or perceived delay could have a material adverse effect on our results of operations, business prospects, and financial condition.

***If our spacecraft fail to operate as intended, it could have a material adverse effect on our business, financial condition, and results of operations.***

The manufacturing, testing, launching and operation of a spacecraft involves complex processes and technology. Our satellites employ advanced technologies and sensors that are exposed to severe environmental stresses that have and could affect the performance of satellites. Hardware component problems and software issues could lead to deterioration in performance or loss of functionality of a spacecraft. In addition, human operators may execute improper commands that may negatively impact a spacecraft's performance. Exposure of our spacecraft to an unanticipated catastrophic event, such as collision with space debris, could reduce the performance of, or completely destroy, the affected spacecraft.

During any period of time in which a spacecraft is not operational, we may lose most or all of the revenue that otherwise would have been derived from it. Our inability to repair or replace a defective type of spacecraft or correct any other technical problem in a timely manner could result in a significant loss of revenue. If a spacecraft experiences a significant anomaly such that its type is no longer operational, it would significantly impact our business, prospects, and profitability. Additionally, any satellite failures could damage our reputation and ability to obtain future customers for our launch services, prevent us from receiving any payments contingent on a successful launch and increase our insurance rates, which could have a material adverse effect on our business and prospects.

Space is a harsh and unpredictable environment where our products and service offerings are exposed to a wide and unique range of environmental risks, including, among others, coronal mass ejections, solar flares and other extreme space weather events and potential collision with space debris or another spacecraft, which could adversely affect our launch vehicle and spacecraft performance.

Although we have some ability to actively maneuver our satellites to avoid potential collisions with space debris or other spacecraft, this ability is limited by, among other factors, uncertainties and inaccuracies in the projected orbit location of and predicted conjunctions with debris objects tracked and cataloged by the U.S. government. Additionally, some space debris is too small to be tracked and therefore its orbital location is completely unknown; nevertheless, this debris is still large enough to potentially cause severe damage or a failure of our launch vehicles or satellites should a collision occur.

***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.***

In recent years, the number of satellites deployed to low-Earth orbits has increased, and publicly announced plans call for many thousands of additional satellite deployments over the next decade. The proliferation of these low-Earth orbit constellations could materially increase the risks of potential collision with space debris or another spacecraft and affect our ability to effectively access sufficient orbital slots to support the expected growth across our business.

***Our revenue, results of operations and reputation may be negatively impacted if our products contain defects or fail to operate in the expected manner.***

We sell complex and technologically advanced products and services, including rocket launch services, mission services, satellites and satellite components. Sophisticated software used in our products and services, including software developed by us, may contain defects that can unexpectedly interfere with the software's intended operation. Defects may also occur in components and products that we manufacture or purchase from third parties. Most of the launch vehicles, satellites and satellite components we have developed must function under demanding and unpredictable operating conditions and in harsh and potentially destructive environments. Our products and services may not be successfully implemented, pass required acceptance criteria, or operate or give the desired output, or we may not be able to detect and fix all defects in the launch vehicles, satellites, satellite components and systems we sell and/or use.

We employ sophisticated design and testing processes and practices, which include a range of stringent factory and on-site acceptance tests with criteria and requirements that are jointly developed with customers. Our systems may not be successfully implemented, pass required acceptance criteria, or operate or give the desired output, or we may not be able to detect and fix all defects in the satellites, products, hardware, and software we sell or resolve any delays or availability issues in the launch services we procure. Failure to do so could result in increased costs, lost revenue and damage to our reputation and may adversely affect our ability to win new contract awards.

***Fluctuations in foreign exchange rates or future hedging activities could in the future have a negative impact on our business.***

We are exposed to foreign exchange risk as certain of our expenses and liabilities are required to be paid in currencies other than the U.S. dollar. We generally maintain our cash and cash equivalents in U.S. dollars or investments denominated in U.S. dollars. Fluctuations in foreign exchange rates, which can be unpredictable, could result in disproportionate increases in our expenses and future liabilities as compared to our revenue and current assets. We do not currently, but may in the future, use hedging strategies or seek to maintain a greater portion of our cash and cash equivalents in foreign currencies or investments denominated in foreign currencies to manage and minimize the impact of exchange rate fluctuations on our consolidated financial statements. If we decide to hedge our foreign currency exchange rate exposure, we may not be able to hedge effectively due to lack of experience, unreasonable costs, or illiquid markets.

***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 ability to produce our current and future satellite and vehicle systems and other components of operation is dependent upon sufficient availability of raw materials, specialized subcontracted labor, and supplied components, which we secure from a limited number of suppliers.

Our reliance on suppliers to secure these raw materials, specialized labor, and supplied components exposes us to volatility in the prices and availability of these items. We may not be able to obtain sufficient supplies of raw materials or supplied components on favorable terms or at all, which could result in delays in the manufacture of our vehicles or increased costs.

In addition, we have in the past experienced and may in the future experience delays in manufacturing or operation as we go through the requalification process with any replacement third-party supplier, as well as the limitations imposed by the ITAR, the EAR, or other restrictions on transfer of sensitive technologies and limitations. Moreover, the imposition of tariffs on such raw materials or supplied components could have a material adverse effect on our operations. Prolonged disruptions in the supply of any of our key raw materials or components, difficulty qualifying new sources of supply, implementing use of replacement materials or new sources of supply or any volatility in prices could have a material adverse effect on our ability to operate in a cost-efficient, timely manner and could cause us to experience cancellations or delays of scheduled missions, customer cancellations or reductions in our prices and margins, any of which could harm our business, financial condition and results of operations.

***Our satellites, vehicles, and related equipment may have shorter useful lives than we anticipate.***

A number of factors will impact the useful lives of our satellites and vehicles, including, among other things, the quality of their design and construction, the durability of their component parts and availability of any replacement components, and the occurrence of any anomaly or series of anomalies or other risks affecting the vehicles during launch and in orbit. In addition, any improvements in technology may make obsolete our existing vehicles or any

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

component of our vehicles prior to the end of its life. If our vehicles and related equipment have shorter useful lives than we currently anticipate, this may lead to delays in increasing the rate of our commercial payloads, which would have a material adverse effect on our business, financial condition, and results of operations.

***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.***

The space transportation industry is still developing and evolving, but we expect it to be highly competitive. Currently, our primary competitors in delivering small satellites into a specific orbit are small launch vehicle providers such as Firefly and Rocket Lab, as well as orbital transfer and service vehicle providers such as D-Orbit, Exotrail, Impulse Space, Launcher, and Quantum Space. Some companies, such as Rocket Lab and Firefly Aerospace, are developing both small launch vehicles and transfer vehicles.

A number of significant competitors produce satellites, buses, and related technologies in the same class as those offered by Momentus. Significant competitors for satellites, buses, and related technologies include York Space, Terran Orbital, Raytheon Blue Canyon, and Airbus. Many of our current and potential competitors are larger and may have substantially greater resources than we have or may expect to have in the future. They may also be able to devote greater resources to the development of their current and future technologies or the promotion of their offerings or offer lower prices. Our current and potential competitors may also establish cooperative or strategic relationships among themselves or with third parties that may further enhance their resources and offerings. Further, it is possible that domestic or foreign companies or governments, some with greater experience in the aerospace industry or greater financial resources than we possess, will seek to provide products or services that compete directly or indirectly with ours in the future. Any such foreign competitor, for example, could benefit from subsidies from more permissive regulatory requirements in, or other protective measures by, its home country.

We believe our ability to compete successfully in delivering satellites to custom orbit at significantly reduced cost to customers depends on a number of factors, which may change in the future due to increased competition, our ability to meet our customers' needs and the frequency and availability of our offerings. If we are unable to compete successfully, our business, financial condition and results of operations could be adversely affected.

***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.***

Our success depends, in significant part, on our ability to protect our intellectual property rights, including our water-based propulsion technology and certain other methodologies, practices, tools, technologies, and technical expertise we utilize in designing, developing, implementing, and maintaining applications and processes used in our vehicles and related technologies. To date, we have relied primarily on trade secrets and other intellectual property laws, non-disclosure agreements with our employees, consultants and other relevant persons and other measures to protect our intellectual property and intend to continue to rely on these and other means. We also try to protect our intellectual property by filing patent applications related to our technology, inventions and improvements that are important to the development of our business. The steps we take to protect our intellectual property may be inadequate.

As of December 31, 2025, we have eight issued patents, four non-U.S. issued patents, and one patent application across U.S., European, and Patent Cooperation Treaty ("PCT") patent systems. Our pending patent applications may not result in patents being issued, which may have a material adverse effect on our ability to prevent others from commercially exploiting products similar to ours. Momentus cannot be certain that it is the first inventor of the subject matter to which it has filed a particular patent application, or if it is the first party to file such a patent application. If another party has filed a patent application to the same subject matter as Momentus, Momentus may not be entitled to the protection sought by the patent application. Momentus also cannot be certain whether the claims included in a patent application will ultimately be allowed in the applicable issued patent. As a result, Momentus cannot be certain that the patent applications that it files will be issued. Further, the scope of protection of issued patent claims is often difficult to determine.

Patents, if issued, may be challenged, invalidated, or circumvented. If our patents are invalidated or found to be unenforceable, we will lose the ability to exclude others from making, using or selling the inventions claimed. Moreover, an issued patent does not guarantee us the right to use the patented technology or commercialize a product using that technology. Third parties may have blocking patents that could be used to prevent us from developing our product. Thus, patents that we may own in the future may not allow us to exploit the rights conferred by our intellectual property protection. Even if issued, they may not be issued with claims sufficiently broad to protect our technologies or may not provide us with a competitive advantage against competitors with similar technologies. Despite our precautions, it may be possible for unauthorized third parties to copy our technology and

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

use information that we regard as proprietary to create technology that competes with ours. Further, the laws of some countries do not protect proprietary rights to the same extent as the laws of the United States, and mechanisms for enforcement of intellectual property rights in some foreign countries may be inadequate. Momentus' competitors may also design around Momentus' issued patents, which may adversely affect Momentus' business, prospects, financial condition, and operating results.

In addition, although we enter into nondisclosure and invention assignment agreements with our employees, enter into non-disclosure agreements with consultants and other parties with whom we have strategic relationships and business alliances and enter into intellectual property assignment agreements with our consultants and vendors, no assurance can be given that these agreements will be effective in controlling access to and distribution of our technology and proprietary information. Further, these agreements do not prevent our competitors from independently developing technologies that are substantially equivalent or superior to our products.

***Protecting and defending against intellectual property claims may have a material adverse effect on our business.***

Our success depends in part upon successful prosecution, maintenance, enforcement and protection of our owned intellectual property. To protect our intellectual property rights, we may be required to spend significant resources to monitor and protect these rights. Litigation may be necessary in the future to enforce our intellectual property rights and to protect our trade secrets. Such litigation could be costly, time consuming and distracting to management and could result in the impairment or loss of portions of our intellectual property. Furthermore, our efforts to enforce our intellectual property rights may be met with defenses, counterclaims and countersuits attacking the validity and enforceability of our intellectual property rights. Our inability to protect our technology, as well as any costly litigation or diversion of our management's attention and resources, could disrupt our business, as well as have a material adverse effect on our financial condition and results of operations. The results of intellectual property litigation are difficult to predict and may require us to stop using certain technologies or offering certain services or may result in significant damage awards or settlement costs. There is no guarantee that any action to defend, maintain or enforce our owned or licensed intellectual property rights will be successful, and an adverse result in any such proceeding could have a material adverse impact on our business, financial condition, operating results, and prospects.

In addition, we may from time-to-time face allegations that we are infringing, misappropriating, or otherwise violating the intellectual property rights of third parties, including the intellectual property rights of our competitors. We may be unaware of the intellectual property rights that others may claim cover some or all of our technology or services. Irrespective of the validity of any such claims, we could incur significant costs and diversion of resources in defending against them, and there is no guarantee any such defense would be successful, which could have a material adverse effect on our business, contracts, financial condition, operating results, liquidity, and prospects.

Even if these matters do not result in litigation or are resolved in our favor or without significant cash settlements, these matters, and the time and resources necessary to litigate or resolve them, could divert the time and resources of our management team and harm our business, our operating results and our reputation.

***We may experience warranty claims for failures, schedule delays or other problems with existing or new products.***

Many of the products we develop and manufacture are technologically advanced systems that must function under demanding operating conditions. The sophisticated and rigorous design, manufacturing and testing processes and practices we employ do not entirely prevent the risk that we may not be able to successfully launch or manufacture our products on schedule or that our products may not perform as intended.

If our products fail to perform adequately, some of our contracts require us to forfeit a portion of our expected profit, receive reduced payments, provide a replacement product or service or reduce the price of subsequent sales to the same customer. Performance penalties may also be imposed if we fail to meet delivery schedules or other measures of contract performance. We do not generally insure against potential costs resulting from any required remedial actions or costs or loss of sales due to postponement or cancellation of scheduled operations or product deliveries.

***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.***

Our international business is subject to both U.S. and foreign laws and regulations, including, without limitation, laws and regulations relating to export/import controls, sanctions, technology transfer restrictions, government contracts and procurement, data privacy and protection, anti-corruption laws, including the Foreign Corrupt Practices Act, the anti-boycott provisions of the U.S. Antiboycott Act of 2018, Part II of the Export Control Reform

Act security restrictions and intellectual property. Failure by us, our employees, affiliates, partners or others with whom we work to comply with applicable laws and regulations could result in administrative, civil, commercial or criminal liabilities, including suspension or debarment from government contracts or suspension of our export/import privileges. New regulations and requirements, or changes to existing ones in the various countries in which we operate can significantly increase our costs and risks of doing business internationally.

Changes in laws, regulations, political leadership and environment, and/or security risks may dramatically affect our ability to obtain any required regulatory approvals and conduct or continue to conduct business in international markets, including sales to customers and purchases from suppliers outside the United States. We may also be impacted by U.S. and foreign national policies and priorities, political decisions and geopolitical relationships, any of which may be influenced by changes in the threat environment, political leadership, geopolitical uncertainties, world events, bilateral and multi-lateral relationships and economic and political factors, and any of which could impact our operations and/or export authorizations, impair our ability to obtain any required regulatory approvals or delay purchasing decisions or payments and the provision of supplies, goods and services including, without limitation, in connection with any government programs. Global economic conditions and fluctuations in foreign currency exchange rates and tariffs could further impact our business. For example, the tightening of credit in financial markets outside of the United States could adversely affect the ability of our customers and suppliers to obtain financing and could result in a decrease in or cancellation of orders for our products and services or impact the ability of our customers to make payments. In particular, the imposition (or threatened imposition) of tariffs by the U.S. government and countermeasures that were, and may be taken, in response thereto could materially adversely impact global economic and political conditions, and disrupt the business of our customers and suppliers, and thereby harm our business.

We also increasingly are dependent on in-country suppliers and we face risks related to their failure to perform in accordance with the contracts and applicable laws, particularly where we rely on a sole source supplier. The services we provide internationally are sometimes in countries with unstable governments, economic or fiscal challenges, military or political conflicts and/or developing legal systems. This may increase the risk to our employees, subcontractors or other third parties, and/or increase the risk of a wide range of liabilities, as well as loss of property or damage to our products.

The occurrence and impact of these factors is difficult to predict, but one or more of them could have a material adverse effect on our financial position, results of operations and/or cash flows.

***Data breaches or incidents involving our technology could damage our business, reputation and brand and substantially harm our business and results of operations.***

If our data and network infrastructure were to fail, or if we were to suffer an interruption or degradation of services in our data center, third-party cloud, and other infrastructure environments, we could lose important manufacturing and technical data, which could harm our business. Our facilities, as well as the facilities of third-parties that maintain or have access to our data or network infrastructure, are vulnerable to damage or interruption from earthquakes, hurricanes, floods, fires, cyber security attacks, terrorist attacks, power losses, telecommunications failures and similar events. In the event that our or any third-party provider's systems or service abilities are hindered by any of the events discussed above, our ability to operate may be impaired. A decision to close facilities without adequate notice, or other unanticipated problems, could adversely impact our operations. Any of the aforementioned risks may be augmented if our or any third-party provider's business continuity and disaster recovery plans prove to be inadequate. Our data center, third-party cloud, and managed service provider infrastructure also could be subject to break-ins, cyber-attacks, sabotage, intentional acts of vandalism and other misconduct, from a spectrum of actors ranging in sophistication from threats common to most industries to more advanced and persistent, highly organized adversaries. Any security breach, including personal data breaches, or incident, including cybersecurity incidents, that we experience could result in unauthorized access to, misuse of or unauthorized acquisition of our internal sensitive corporate data, such as financial data, intellectual property, or data related to contracts with commercial or government customers or partners. Such unauthorized access, misuse, acquisition, or modification of sensitive data may result in data loss, corruption or alteration, interruptions in our operations or damage to our computer hardware or systems or those of our employees and customers. Moreover, negative publicity arising from these types of disruptions could damage our reputation. We may not carry sufficient business interruption insurance to compensate us for losses that may occur as a result of any events that cause interruptions in our service. Significant unavailability of our services due to attacks could cause users to cease using our services and materially and adversely affect our business, prospects, financial condition and results of operations.

We use software which we have developed in our technology infrastructure, which we seek to continually update and improve. Replacing such systems is often time-consuming and expensive and can also be intrusive to daily

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

business operations. Further, we may not always be successful in executing these upgrades and improvements, which may occasionally result in a failure of our systems. We may experience periodic system interruptions from time to time. Any slowdown or failure of our underlying technology infrastructure could harm our business, reputation and ability to execute on our business plan, which could materially adversely affect our results of operations. Our disaster recovery plan or those of our third-party providers may be inadequate, and our business interruption insurance may not be sufficient to compensate us for the losses that could occur.

***We are highly dependent on our senior management team and other highly skilled personnel.***

Our success depends, in significant part, on the continued services of our senior management team and on our ability to attract, motivate, develop and retain a sufficient number of other skilled personnel, manufacturing and quality assurance, engineering, design, finance, marketing, sales and support personnel. Certain members of our senior management team have extensive experience in the aerospace industry, and we believe that their depth of experience is instrumental to our continued success. The loss of any one or more members of our senior management team for any reason, including resignation or retirement, could impair our ability to execute our business strategy and may have a material adverse effect on our business, financial condition and results of operations.

***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.***

Our quarterly and annual operating results may fluctuate significantly, which makes it difficult for us to predict our future operating results. These fluctuations may occur due to a variety of factors, many of which are outside of our control, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to successfully test and validate our technology, including through demonstration missions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the number and weight of payloads we are able to schedule for launch during a period;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• unexpected weather patterns, natural disasters, or other events that force a cancellation or rescheduling of launches;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• launch vehicle failures which result in cancellation or rescheduling of future launches;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the availability and cost of raw materials or supplied components critical for the manufacture and operation of our vehicles;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• developments involving our competitors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in governmental regulations or in the status of our regulatory approvals or applications;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• future accounting pronouncements or changes in our accounting policies; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• general market conditions and other factors, including factors unrelated to our operating performance or the operating performance of our competitors.

The individual or cumulative effects of factors discussed above could result in large fluctuations and unpredictability in our quarterly and annual operating results. As a result, comparing our operating results on a period-to-period basis may not be meaningful.

This variability and unpredictability could also result in our failing to meet the expectations of industry or financial analysts or investors for any period. If our revenue or operating results fall below the expectations of analysts or investors or below any guidance we may provide, or if any guidance we provide is below the expectations of analysts or investors, the price of our Class A common stock could decline substantially. Such a stock price decline could occur even when we have met any previously publicly stated guidance we may provide.

***Momentus' ability to use its net operating loss carryforwards and certain other tax attributes may be limited.***

As of December 31, 2025, Momentus had $259.6 million of U.S. federal and $103.4 million of state net operating loss carryforwards available to reduce future taxable income. The U.S. federal operating loss carryforwards incurred after 2017 will be carried forward indefinitely for U.S. federal tax purposes. While these federal net operating losses ("NOLs") can be carried forward indefinitely, California net operating losses begin to expire in the year ending December 31, 2037. It is possible that Momentus will not generate taxable income in time to use these net operating loss carryforwards before their expiration or at all. Under legislative changes made in December 2017, U.S. federal net operating losses incurred in 2018 and in future years may be carried forward indefinitely, but the deductibility of such net operating losses is limited. In addition, the federal and state net operating loss carryforwards and certain tax

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

credits may be subject to significant limitations under Section 382 and Section 383 of the U.S. Internal Revenue Code (the "U.S. Tax Code"), respectively, and similar provisions of state law. Under those sections of the U.S. Tax Code, if a corporation undergoes an "ownership change," the corporation's ability to use its pre-change net operating loss carryforwards and other pre-change attributes, such as research tax credits, to offset its post-change income or tax may be limited. In general, an "ownership change" will occur if there is a cumulative change in our ownership by "5-percent stockholders" that exceeds 50 percentage points over a rolling three-year period. Similar rules may apply under state tax laws. Momentus has not yet undertaken an analysis of whether the Business Combination constitutes an "ownership change" for purposes of Section 382 and Section 383 of the U.S. Tax Code.

***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.***

We may in the future be subject to substantial litigation, regulatory actions, government investigations, proceedings, and similar actions including matters related to commercial disputes, intellectual property, employment, securities laws, disclosures, whistleblower, environmental, tax, accounting, class action, and product liability, as well as trade, regulatory, and other claims related to our business and our industry. Such matters can be time-consuming, divert management's attention and resources, cause us to incur significant expenses or liability or require us to change our business practices. Because of the potential risks, expenses and uncertainties of litigation, we may, from time to time, settle disputes, even where we believe that we have meritorious claims or defenses. Because litigation is inherently unpredictable, we cannot assure you that the results of any of these actions will not have a material adverse effect on our business, operating results, or financial condition.

Securities class actions, shareholder derivative actions, and other future litigation matters may be time-consuming, divert management's attention and resources, cause the Company to incur significant defense and settlement costs or liability, even if we believe the claims asserted against us are without merit. We intend to vigorously defend against all such claims. While a certain amount of insurance coverage is available for expenses or losses associated with current or future lawsuits, this coverage may not be sufficient. Determining reserves for any litigation is a complex, fact-intensive process that is subject to judgment calls. It is possible that a resolution of one or more such proceedings could require us to make substantial payments to satisfy judgments, fines or penalties or to settle claims or proceedings, any of which could harm our business. Based on information currently available, we are unable to estimate reasonably a possible loss or range of possible losses, if any, with regard to the current securities class actions, shareholder derivative actions and other lawsuits; therefore, no litigation reserve has been recorded in our consolidated balance sheet. Although we plan to defend against the securities class actions, shareholder derivative actions and other lawsuits vigorously, we cannot assure that the results of these actions, either individually or in the aggregate, will not 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.***

The occurrence of one or more natural disasters such as fires, floods and earthquakes, unusual weather conditions, epidemic or pandemic outbreaks, terrorist attacks or disruptive political events where our facilities or the launch facilities our transport partners use are located, or where our third-party suppliers' facilities are located, could adversely affect our business. Natural disasters including tornados, hurricanes, floods, and earthquakes may damage our facilities, the launch facilities we use or those of our suppliers, which could have a material adverse effect on our business, financial condition and results of operations. Severe weather, such as rainfall, snowfall or extreme temperatures, may impact the ability for launches to occur as planned, resulting in additional expense to reschedule, thereby reducing our sales and profitability. Terrorist attacks, actual or threatened acts of war or the escalation of current hostilities, or any other military or trade disruptions impacting our domestic or foreign suppliers of components of our products, may impact our operations by, among other things, causing supply chain disruptions and increases in commodity prices, which could adversely affect our raw materials or transportation costs. These events also could cause or act to prolong an economic recession or depression in the United States or abroad. To the extent these events also impact one or more of our suppliers or result in the closure of any of their facilities or our facilities, we may be unable to maintain launch schedules or fulfill our other contracts.

***Our restructurings and associated organizational changes may not adequately reduce our expenses, may lead to additional workforce attrition, and may cause operational disruptions.***

We have experienced workforce attrition in various functions across our business. Our efforts to operate our operations with a limited workforce may not be successful in preventing disruption to our business. A limited workforce, and any further reductions, as well as the perceptions of our vendors, customers, potential customers, and investors regarding these actions, could adversely affect our ability to operate the business and achieve business

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

objectives, which could consequently materially adversely affect our business, financial condition, results of operations, and share price. Further loss of one or more of our key employees, additional loss of multiple employees in particular functions, and/or our inability to attract replacement or additional qualified personnel could substantially impair our ability to operate our business and implement our business plan.

***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.***

We are not able to predict with certainty the amount of time and resources necessary to successfully identify, pursue and execute any strategic alternative or to obtain additional financing. The diversion of management's attention may materially adversely affect the conduct of our business, and, as a result, our financial condition and results of operations. The additional expense we accrue in connection with our review of strategic alternatives and pursuit of additional capital may materially adversely impact our financial condition and partially offset the value of any strategic plan we may pursue or additional financing we may be able to obtain. In addition, doubts about our ability to continue as a going concern could impact our relationships with customers, vendors and other third parties and our ability to obtain, maintain or renew contracts with them, or negatively impact our negotiating leverage with such parties, which could have a material adverse effect on our business, financial condition and results of operations. Furthermore, any loss of key personnel, employee attrition or material erosion of employee morale arising out of doubts about our ability to operate as a going concern could have a material adverse effect on our ability to effectively conduct our business and could impair our ability to execute our strategy and implement our business objectives, thereby having 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.***

We are required to comply with U.S. export control laws and regulations, including the ITAR administered by the U.S. Department of State's Directorate of Defense Trade Controls ("DDTC") and the EAR administered by the U.S. Department of Commerce's Bureau of Industry and Security ("BIS"). Pursuant to these foreign trade control laws and regulations, we are required, among other things, to (i) maintain a registration under the ITAR, (ii) determine the proper licensing jurisdiction and export classification of products, software, and technology, and (iii) obtain licenses or other forms of U.S. government authorization to engage in the conduct of our space transport business. Violations of applicable export control laws and related regulations could result in criminal and administrative penalties, including fines, possible denial of export privileges, and debarment, which could have a material adverse impact on our business, including our ability to enter into contracts or subcontracts for U.S. government customers. U.S. export licenses are required to transfer or make accessible certain of the Company's products, software and technical information to its non-U.S. employees ("deemed exports").

The Company has, from time-to-time, self-reported potential violations of export control laws to the Office of Export Enforcement (the "OEE") of BIS as noted below. While these incidents did not result in any monetary or non-monetary penalties, if we are found to be in violation of export control laws and regulations in the future, we could face civil and criminal liabilities, monetary and non-monetary penalties, the loss of export or import privileges, debarment and/or reputational harm.

The inability to secure and maintain necessary export authorizations could negatively impact our ability to compete successfully or to operate our spaceflight business as planned. For example, if we were unable to obtain or maintain our licenses to export certain spacecraft hardware, we would be effectively prohibited from launching our vehicles from certain non-U.S. locations, which would limit the number of launch providers we could use. In addition, if we were unable to obtain a Technical Assistance Agreement from the DDTC to export certain launch-related services, we would experience difficulties or even be unable to perform integration activities necessary to safely integrate our transfer vehicles to non-U.S. launch vehicles. In both cases, these restrictions could lead to higher launch costs, which may have a material adverse impact on our results of operations. Similarly, if we were unable to secure effective export licensure to authorize the full scope of activity with a foreign partner or supplier, we may be required to make design changes to spacecraft or updates to our supplier chain, which may result in increased costs to us or delays in vehicle launches.

Any changes in the export control regulations or U.S. government licensing policy, such as those necessary to implement U.S. government commitments to multilateral control regimes, may restrict our operations. There is no inherent right to perform an export and given the significant discretion the government has in adjudicating such

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

authorizations in furtherance of U.S. national security and foreign policy interests, there can be no assurance we will be successful in our current and future efforts to secure and maintain necessary licenses, registrations, or other U.S. government regulatory approvals.

In addition, U.S. export control laws continue to change. For example, the control lists under the ITAR and the EAR are periodically updated to reclassify specific types of export-controlled technology. For example, any changes to the jurisdictional assignment of controlled data or hardware used by Momentus could result in the need for different export authorizations, each then subject to a subsequent approval. Similarly, should exceptions or exemptions under the EAR or the ITAR, respectively, be changed, Momentus' activities otherwise authorized via these mechanisms may become unavailable and could result in the need for additional export authorizations. Additionally, changes to the administrative implementation of export control laws at the agency level may suddenly change as a result of geo-political events, which could result in existing or proposed export authorization applications being viewed in unpredictable ways, or potentially rejected, as a result of the changed agency level protocol.

***Our business is subject to a wide variety of additional extensive and evolving government laws and regulations. Failure to comply with such laws and regulations could have a material adverse effect on our business.***

We are subject to a wide variety of laws and regulations relating to various aspects of our business, including with respect to our space transport operations, employment and labor, health care, tax, privacy and data security, health and safety, and environmental issues. Laws and regulations at the foreign, federal, state and local levels frequently change, especially in relation to new and emerging industries, and we cannot always reasonably predict the impact from, or the ultimate cost of compliance with, current or future regulatory or administrative changes. We monitor these developments and devote a significant amount of management's time and external resources towards compliance with these laws, regulations, and guidelines, and such compliance places a significant burden on management's time and other resources, and it may limit our ability to expand into certain jurisdictions. Moreover, changes in law, the imposition of new or additional regulations or the enactment of any new or more stringent legislation that impacts our business could require us to change the way we operate and could have a material adverse effect on our sales, profitability, cash flows, and financial condition.

Failure to comply with these laws or regulations or failure to satisfy any criteria or other requirement under such laws or regulations, such as with respect to obtaining and maintaining licenses, certificates, authorizations and permits critical for the operation of our business, may result in civil penalties or private lawsuits, or result in a delay or the denial, suspension or revocation of licenses, certificates, authorizations or permits, which would prevent us from operating our business. For example, commercial space launches and the operation of our space transport system in the United States require licenses and permits from the FCC and review by other agencies of the U.S. government, including the FAA, the U.S. Department of Defense, and NASA.

License or operational approval can include an interagency review of safety, operational, national security, and foreign policy and international obligations implications, as well as a review of foreign ownership. The FAA denial of Vigoride-1 payload review unrelated to a launch license was the result of national security concerns related to foreign ownership and control that arose during an interagency review. Future denials of similar licenses or operational approvals may occur and could have a material adverse effect on our operations, sales, profitability, cash flows and overall financial condition. In addition, failure of Momentus or its officers to comply with governmental orders or agreements may expose Momentus and its officers to liability or penalties.

Regulation of our industry is still evolving, and new or different laws or regulations could affect our operations, increase direct compliance costs for us or cause any third-party suppliers or contractors to raise the prices they charge us because of increased compliance costs. Application of these laws and regulations to our business may negatively impact our performance in various ways, limiting the collaborations we may pursue, further regulating the export and re-export of our products, services, and technology from the United States and abroad, and increasing our costs and the time necessary to obtain required authorizations. The adoption of a multi-layered regulatory approach to any one of the laws or regulations to which we are or may become subject, particularly where the layers are in conflict, could require alteration of our manufacturing processes or operational parameters which may adversely impact our business. We may not be in complete compliance with all such requirements at all times and, even when we believe we are in complete compliance, a regulatory agency may determine that we are not.

***Momentus and its customers and suppliers could be materially impacted by disruptions in U.S. government operations and funding.*** 

Any disruptions in federal government operations could have a material adverse effect on our revenues, operational delays, earnings, and cash flows. A prolonged failure to maintain significant U.S. government operations for Momentus, its customers and suppliers, particularly those pertaining to our business, could have a material adverse

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

effect on our revenues, operational delays, earnings, and cash flows. Continued uncertainty related to recent and future government shutdowns, the budget and/or the failure of the government to enact annual appropriations, such as long-term funding under a continuing resolution, could have a material adverse effect on our revenues, earnings and cash flows. Additionally, disruptions in government operations may negatively impact regulatory approvals and guidance that are important to our operations.

***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.***

Current U.S. government policy enables the U.S. government's use of commercial data, space infrastructure, and mission providers to support U.S. national security objectives. U.S. government policy is subject to change and any change in policy away from supporting the use of commercial data and space infrastructure / mission providers to meet U.S. government service and space infrastructure/mission needs, or any material delay or cancellation of planned U.S. government programs could materially adversely affect our revenue 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.***

We derive revenue from existing contracts with the U.S. government, and we may enter into additional contracts with the U.S. government in the future, which subject our business to statutes and regulations applicable to companies doing business with the government, including the Federal Acquisition Regulation. These government contracts customarily contain provisions that give the government substantial rights and remedies, many of which are not typically found in commercial contracts and which are unfavorable to contractors. For instance, most U.S. government agencies include provisions that allow the government to unilaterally terminate or modify contracts for convenience, and in that event, the counterparty to the contract may generally recover only its incurred or committed costs and settlement expenses and profit on work completed prior to the termination. If the government terminates a contract for default, the defaulting party may be liable for any extra costs incurred by the government in procuring undelivered items from another source.

In addition, government contracts normally contain additional requirements that may increase our costs of doing business, reduce our profits, and expose us to liability for failure to comply with these terms and conditions. These requirements include, for example:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• specialized disclosure and accounting requirements unique to government contracts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• financial and compliance audits that may result in potential liability for price adjustments, recoupment of government funds after such funds have been spent, civil and criminal penalties, or administrative sanctions such as suspension or debarment from doing business with the U.S. government;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• public disclosures of certain contract and company information; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• mandatory socioeconomic compliance requirements, including labor requirements, non-discrimination and affirmative action programs and environmental compliance requirements.

Government contracts are also generally subject to greater scrutiny by the government, which can initiate reviews, audits and investigations regarding our compliance with government contract requirements. In addition, if we fail to comply with government contracting laws, regulations and contract requirements, our contracts may be subject to termination, and we may be subject to financial and/or other liability under our contracts, the Federal Civil False Claims Act (the "False Claims Act") (including treble damages and other penalties), or criminal law. In particular, the False Claims Act's "whistleblower" provisions also allow private individuals, including present and former employees, to sue on behalf of the U.S. government. Any penalties, damages, fines, suspension, or damages could adversely affect our ability to operate our business and our financial results.

***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.***

We collect, store, process, and use personal information and other customer data, including medical information, and we rely in part on third parties that are not directly under our control to manage certain of these operations and to collect, store, process and use payment information. Due to the sensitivity of the personal information and data we and these third parties manage and expect to manage in the future, as well as the nature of our customer base, the

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

security features of our information systems are critical. A variety of federal, state and foreign laws and regulations govern the collection, use, retention, sharing and security of this information. Laws and regulations relating to privacy, data protection and consumer protection are evolving and subject to potentially differing interpretations. These requirements may not be harmonized, may be interpreted and applied in a manner that is inconsistent from one jurisdiction to another or may conflict with other rules or our practices. As a result, our practices may not have complied or may not comply in the future with all such laws, regulations, requirements and obligations. For example, in January 2020, the California Consumer Privacy Act ("CCPA") took effect, which provides new operational requirements for companies doing business in California. Compliance with the new obligations imposed by the CCPA depends in part on how particular regulators interpret and apply them. If we fail to comply with the CCPA or if regulators assert that we have failed to comply with the CCPA, we may be subject to certain fines or other penalties. On November 3, 2020, voters passed the California Privacy Rights Act, which builds upon the CCPA and expands consumer privacy rights to more closely align with the European Union's General Data Protection Regulation (the "GDPR") discussed below.

We expect that new industry standards, laws and regulations will continue to be proposed regarding privacy, data protection and information security in many jurisdictions. We cannot yet determine the impact such future laws, regulations and standards may have on our business. Complying with these evolving obligations is costly. For instance, expanding definitions and interpretations of what constitutes "personal data" (or the equivalent) within the United States, the European Economic Area (the "EEA"), and elsewhere may increase our compliance costs and legal liability.

We are also subject to additional privacy rules, many of which, such as the GDPR and national laws supplementing the GDPR, such as in the United Kingdom, are significantly more stringent than those currently enforced in the United States. The law requires companies to meet stringent requirements regarding the handling of personal data of individuals located in the EEA. The law also includes significant penalties for noncompliance, which may result in monetary penalties of up to the higher of €20.0 million or 4% of a group's worldwide turnover for the preceding financial year for the most serious violations. The GDPR and other similar regulations require companies to give specific types of notice and informed consent is required for certain actions, and the GDPR also imposes additional conditions in order to satisfy such consent, such as bundled consents.

A significant data breach or any failure, or perceived failure, by us to comply with any federal, state or foreign privacy or consumer protection-related laws, regulations or other principles or orders to which we may be subject or other legal obligations relating to privacy or consumer protection could adversely affect our reputation, brand and business, and may result in claims, investigations, proceedings or actions against us by governmental entities or others or other penalties or liabilities or require us to change our operations and/or cease using certain data sets. Depending on the nature of the information compromised, we may also have obligations to notify users, law enforcement or payment companies about the incident and may need to provide some form of remedy, such as refunds, for the individuals affected by the incident.

**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.***

On September 24, 2024, the Company received a letter from the Listing Qualifications Staff of Nasdaq indicating that the Company was subject to delisting for failure to satisfy Nasdaq's requirements for continued listing set forth in Nasdaq Listing Rule 5550(a)(2) (the "Minimum Bid Price Requirement"). The Company also had received deficiency letters on May 23, 2024, and August 21, 2024, respectively, from the Staff notifying the Company that the Company had not filed its Quarterly Reports on Form 10-Q for the periods ending March 31, 2024, and June 30, 2024, respectively, as required for continued listing on the Nasdaq under Nasdaq Listing Rule 5250(c)(1) (the "Periodic Reporting Requirement"). Pursuant to Nasdaq Listing Rule 5810(d)(2), the failures to comply with the Periodic Reporting Requirement individually became additional and separate bases for delisting.

On October 15, 2024, the Company filed its Quarterly Reports on Form 10-Q for the quarters ended March 31, 2024, and June 30, 2024, resolving the deficiencies related to the Periodic Reporting Requirement. On October 17, 2024, the Company received further notice from the Listing Qualifications Department of Nasdaq notifying the Company that it was not in compliance with the requirements of Nasdaq Listing Rule 5550(b) as a result of not having a minimum of $2.5 million in stockholders' equity for continued listing as of June 30, 2024, a market value of listed securities of at least $35.0 million, or net income from continuing operations of $0.5 million in the most recently completed fiscal year or in two of the last three most recently completed fiscal years (the "Equity Rule").

As permitted by Nasdaq rules, the Company timely requested a hearing before a Nasdaq Hearing Panel to appeal Nasdaq's delisting determination. The Company requested and received a stay of the suspension of trading and delisting of the Company's Class A common stock pending the conclusion of the hearing process, which allowed the Company's Class A common stock to remain listed on Nasdaq at least until the Panel renders a decision following the hearing. The hearing before the Panel was held on November 14, 2024, at which the Company requested a suspension of delisting pending its return to compliance.

The Company called a special meeting of stockholders on December 2, 2024, to approve a reverse stock split to regain compliance with Nasdaq rules. On December 12, 2024, the Company effected a 1-for-14 reverse stock split, and on December 27, 2024, the Company's Class A common stock closed above the minimum bid price for ten consecutive trading days as required to regain compliance with the Minimum Bid Price Requirement.

On January 13, 2025, the Company received a letter issued by the Panel granting the Company's request to continue its listing on Nasdaq until April 15, 2025, while the Company executed its plan to regain compliance with the requirements of the Equity Rule.

As disclosed in the Company's Current Report on Form 8-K filed on April 14, 2025, on April 12, 2025, the Company entered into the Master Services Agreement (the "MSA") with Velo3D, Inc. ("VLD"), pursuant to which VLD will provide services to design and produce components and systems that will be utilized by the Company or its customers in its spacecraft, systems, and components. In exchange for the services, the Company issued an aggregate of 26,749 shares of the Company's Class A common stock and 673,408 shares of non-voting Series A Convertible Preferred Stock.

On June 24, 2025, the Company announced that it had received a letter from Nasdaq providing written confirmation that the Company has regained compliance with Nasdaq's rules. Nasdaq has indicated that if the Company's stockholder's equity as of June 30, 2025, included in the Company's Quarterly Report on Form 10-Q for the quarter ended June 30, 2025, does not show a stockholder's equity of at least $2.5 million, then the Company may again be subject to delisting from Nasdaq. In the Company's Quarterly Report on Form 10-Q for the quarter ended June 30, 2025, filed with the SEC on August 19, 2025, the Company reported a stockholders' deficit of approximately $10.0 million.

The MSA with VLD provided for the cancellation of shares of the Company's capital stock held by VLD in certain circumstances upon expiration or termination. On August 14, 2025, the Company irrevocably waived its right under the MSA to cancel such shares upon expiration or termination of the MSA.

In the Company's Quarterly Report on Form 10-Q for the quarter ended September 30, 2025, filed with the SEC on November 20, 2025, the Company reported a stockholders' deficit of approximately $0.7 million.

In order to maintain compliance with the Minimum Bid Price Requirement, the Company effected a reverse stock split of the Company's Class A common stock at a ratio of 1-for-17.85, which went into effect at 5:00 p.m. Eastern Time on December 17, 2025, and on January 2, 2026, the Company's Class A common stock closed above the minimum bid price for ten consecutive trading days as required to regain compliance with the Minimum Bid Price Requirement.

There can be no assurance that the Company will be able to maintain compliance with the Equity Rule, the Minimum Bid Price Requirement, the Periodic Reporting Requirement, or other applicable Nasdaq listing rules, that the Company will be able to successfully implement a reverse stock split if it decides to pursue one, that the Panel will grant any future request from the Company for a suspension of delisting on Nasdaq, or that the Company's appeal of a delisting determination will be successful. Additionally, if we fail to meet the Minimum Bid Price Requirement, we are not eligible for a 180-day cure period from Nasdaq to regain compliance with such requirement because we have conducted a reverse stock split in the past year and thus we would be immediately delisted.

If at the time of filing of the Company's next periodic financial statements the Company does not evidence compliance with the Equity Rule, the Company may again be subject to delisting from Nasdaq. If the Company's Class A common stock loses its listing on the Nasdaq Capital Market, the Company's Class A common stock would likely trade in the over-the-counter market. If the Company's Class A common stock were to trade on the over-the-counter market, selling the Company's Class A common stock could be more difficult because smaller quantities of shares would likely be bought and sold, transactions could be delayed, and security analysts' coverage of us may be reduced. In addition, in the event the Company's Class A common stock is delisted, broker-dealers have certain regulatory burdens imposed upon them, which may discourage broker-dealers from effecting transactions in the Company's Class A common stock, further limiting the liquidity of such shares. A determination that the Company's Class A common stock is a "penny stock" would require brokers trading in the Company's Class A common stock to adhere to even more stringent rules and possibly result in a reduced level of trading activity in the

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

secondary trading market for the Company's Class A common stock. These factors could result in lower prices and larger spreads in the bid and ask prices for the Company's Class A common stock. Such delisting from the Nasdaq Capital Market and continued or further declines in the price of shares of the Company's Class A common stock could also greatly impair our ability to raise additional necessary capital through equity or debt financing, and could significantly increase the ownership dilution to stockholders caused by our issuing equity in financing or other transactions.

***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.***

As of March 27, 2026, we had outstanding 2,096,947 warrants to purchase of our Class A common stock, held by a variety of third parties. The exercise prices of these warrants range from $4.38 per share to $143,692.50 per share. If a substantial portion of these warrants are exercised, we would be required to issue a material number of shares of our Class A common stock, which would dilute the ownership interests of our existing stockholders. Any such dilution could be substantial, particularly if the exercise prices of the warrants are below the then-current trading price of our Class A common stock.

In addition, the existence of these outstanding warrants, and the potential issuance of shares upon their exercise, may create a circumstance commonly referred to as a "warrant overhang." Market participants may anticipate that warrant holders will seek to realize value by exercising warrants and selling the underlying shares (or by engaging in other transactions involving our securities). As a result, the market price of our Class A common stock could be adversely affected by actual sales of shares issued upon exercise of warrants, by the perception that such sales may occur, or by the increased number of shares that could become available for future sale. These dynamics could cause the trading price of our Class A common stock to decline, increase volatility, and make it more difficult for us and our stockholders to sell equity securities at a time and price deemed appropriate.

Our warrants also include change of control protections that could significantly reduce the proceeds otherwise available to holders of our Class A common stock and may discourage or impede a transaction. Most, if not all, of our outstanding warrants provide that, upon the occurrence of certain change of control or similar fundamental transactions, the warrant holders may be entitled to receive consideration based on the Black-Scholes value of the warrants (or an economically similar make-whole amount), which may be payable in cash, shares, or a combination thereof, depending on the terms of the applicable warrant and the structure of the transaction. Because the Black-Scholes value of a warrant reflects, among other things, the market price and volatility of our Class A common stock, the remaining term of the warrant, and prevailing interest rates, the aggregate amount payable or issuable to warrant holders in connection with a change of control could be material. If the make-whole is settled in shares, it could substantially increase the number of shares issued in connection with the transaction; if settled in cash (or a mix of cash and shares), it could materially reduce the cash proceeds available for distribution to holders of our Class A common stock. In either case, these provisions could operate as an additional cost of an acquisition and may deter, delay, or prevent a change of control transaction that might otherwise be beneficial to our stockholders, including by reducing the amount an acquiror is willing to pay, complicating transaction economics, or making a transaction less attractive relative to other opportunities.

Further, the warrant overhang and change of control protections may impair our ability to raise additional capital through equity or equity-linked financings. Potential investors may discount the price they are willing to pay for our securities due to the risk of dilution from warrant exercises and the possibility that warrant make-whole obligations could divert value in a strategic transaction. If we are unable to access capital on acceptable terms, our ability to fund operations, pursue strategic initiatives, and satisfy our obligations could be materially adversely affected.

We have pursued warrant inducement transactions in the past and may pursue additional transactions in the future, which could increase dilution and may not achieve the intended results. From time to time, we have entered into transactions intended to encourage warrant holders to exercise, exchange, amend, or otherwise restructure their warrants (including "warrant inducement" transactions). These transactions have involved, and any future transactions may involve, the issuance of additional warrants to purchase shares of Class A common stock and/or other securities (including at a discount to prevailing market prices), the modification of existing warrant terms (including exercise price reductions or other economic concessions), or other consideration. As a result, warrant inducement transactions increase our warrant overhang and can be dilutive to existing stockholders. Moreover, such transactions may not improve our stock price, may not be available on terms acceptable to us (or at all), and may be undertaken at times when the market for our securities is volatile or when we have limited negotiating leverage. Even if completed, these transactions may not prevent future dilution, may not meaningfully reduce the economic impact of the warrant change of control provisions, and could be viewed negatively by the market, any of which could adversely affect the trading price of our Class A common stock.

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

Accordingly, our outstanding warrants and related provisions could materially and adversely affect the trading price of our common stock, the value received by holders of our Class A common stock in a change of control transaction, our ability to raise additional capital, and the likelihood, timing, and terms of 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.***

We have outstanding convertible notes that may be converted into shares of our Class A common stock, which could result in substantial dilution to existing stockholders. As of December 31, 2025, approximately $1.6 million principal amount of convertible notes were outstanding and convertible at an approximate conversion price of $19.92 per share. The investor also has the right, at its option, to purchase up to an additional $4.0 million of convertible notes on substantially the same terms, which would increase the amount of debt potentially convertible into shares of our Class A common stock. In addition, any such additional investment would include 100% warrant coverage, which would further increase the number of shares issuable and result in further dilution.

In addition, as of December 31, 2025, we had approximately $2.4 million principal amount of convertible notes that are convertible into shares of our Class A common stock at the lower of (i) $19.81 per share and (ii) a 10% discount to the closing price of the Class A common stock, as reported on Nasdaq, on the trading day preceding the holder's election to convert, but in no event lower than $3.57 per share. Because the conversion price for these notes may be based on a discount to market prices, the number of shares issuable upon conversion may increase significantly if the market price of our Class A common stock declines, and conversions could place additional downward pressure on our stock price. The closing price of our Class A common stock on December 31, 2025 was $4.87, meaning that these convertible notes may convert at or near the $3.57 per share floor. We anticipate that the holder may convert some or all of these notes prior to May 1, 2026, which could result in the issuance of a significant number of shares, materially dilute existing stockholders, and adversely affect the trading price and volatility of our Class A common stock.

Furthermore, as of December 31, 2025, approximately $0.5 million principal amount of convertible notes were outstanding and convertible at an approximate conversion price of $29.81 per share.

***An active trading market for our Class A common stock may never develop or be sustained.***

The price of our Class A common stock may fluctuate significantly due to general market and economic conditions and forecasts, our general business condition and the release of our financial reports. An active trading market for our Class A common stock may not develop or continue or, if developed, may not be sustained, which would make it difficult for stockholders to sell their shares of Class A common stock at an attractive price (or at all). The market price of our Class A common stock may decline below stockholders' deemed purchase price, and they may not be able to sell their shares of Class A common stock at or above that price (or at all). Additionally, if our Class A common stock is delisted from Nasdaq for any reason, and is quoted on the OTC Bulletin Board, an inter-dealer automated quotation system for equity securities that is not a national securities exchange, the liquidity and price of our Class A common stock may be more limited than if we were quoted or listed on Nasdaq or another national securities exchange. Stockholders may be unable to sell Class A common stock unless a market can be established or 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.***

If an active market for our Class A common stock and warrants develops and continues, the trading price of our Class A common stock and warrants could be volatile and subject to wide fluctuations. The trading price of our Class A common stock and warrants depends on many factors, including those described in this "*Risk Factors*" section, many of which are beyond our control and may not be related to our operating performance. Any of the factors listed below could have a material adverse effect on investment in our Class A common stock and warrants, and our Class A common stock and warrants may trade at prices significantly below the price paid for them. In such circumstances, the trading price of our Class A common stock and warrants may not recover and may experience a further decline.

Factors affecting the trading price of our Class A common stock and warrants may include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• actual or anticipated fluctuations in our quarterly financial results or the quarterly financial results of companies perceived to be similar to us;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in the market's expectations about our operating results;

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the public's reaction to our press releases, our other public announcements and our filings with the SEC;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• speculation in the press or investment community;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• actual or anticipated developments in our business or our competitors' businesses or the competitive landscape generally;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our operating results failing to meet the expectation of securities analysts or investors in a particular period;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in financial estimates and recommendations by securities analysts concerning us or the market in general;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• operating and stock price performance of other companies that investors deem comparable to us;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• publications of research reports by securities analysts about us, our competitors, or the space industry;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in laws and regulations affecting our business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• commencement of, or involvement in, litigation involving us;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in our capital structure, such as future issuances of securities or the incurrence of additional debt;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the volume of Class A common stock available for public sale;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any major change in our board of directors or management;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• sales of substantial amounts of Class A common stock by directors, officers or significant stockholders or the perception that such sales could occur;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• general economic and political conditions such as recessions, interest rates, fuel prices, trade wars, pandemics, epidemics, currency fluctuations and acts of war or terrorism; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• other risk factors listed under this "*Risk Factors*" section.

***Future sales of shares by Company officers, directors and other insiders may adversely affect the market price of our Class A common stock.***

Sales of shares of our Class A common stock by Company officers, directors and other insiders, regardless of the actual reason for such sales, may be perceived negatively by the market, which could adversely affect the market price of our Class A common stock and make it more difficult for stockholders to sell their Class A common stock at a favorable time and price.

***Future sales of shares by existing stockholders may adversely affect the market price of our Class A common stock.***

Sales of a substantial number of shares of our Class A common stock in the public market, or the perception that such sales could occur, could adversely affect the market price of our Class A common stock and may make it more difficult to sell Class A common stock at a favorable time and price.

***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.***

The trading market for our Class A common stock and warrants will depend, in part, on the research and reports that securities and industry analysts publish about us, our business and our market. No securities analysts have published research on our stock in the last 12 months. If analysts do not publish research on our stock in the future, then our stock price and trading volume could be negatively impacted. In the event securities or industry analysts initiate coverage, if one or more of the analysts who cover us downgrade our stock, publish inaccurate or unfavorable research about our business or our market, or provide more favorable relative recommendations about our competitors, our stock price would likely 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.***

Certain provisions of our Second Amended and Restated Certificate of Incorporation, as amended, as well as our Amended and Restated Bylaws, as amended, may have the effect of rendering more difficult, delaying, or preventing a change of control or changes in our management. These provisions provide for, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a classified Board of Directors whose members serve staggered three-year terms;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the authorization of "blank check" preferred stock, which could be issued by the Board of Directors without stockholder approval and may contain voting, liquidation, dividend, and other rights superior to our Class A common stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a limitation on the ability of, and providing indemnification to, our directors and officers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a requirement that special meetings of our stockholders can be called only by our Board of Directors acting by a written resolution by a majority of the directors then in office, the Chairperson of the Board of Directors, our Chief Executive Officer, or our Lead Independent Director;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a requirement of advance notice of stockholder proposals for business to be conducted at meetings stockholders and for nominations of candidates for election to the Board of Directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a requirement that our directors may be removed only for cause and by a two-thirds (2/3) vote of the stockholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a prohibition on stockholder action by written consent;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a requirement that vacancies on our Board of Directors may be filled only by a majority of Directors then in office or by a sole remaining Director (subject to limited exceptions), even though less than a quorum; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a requirement of the approval of the Board of Directors or the holders of at least two-thirds of our outstanding shares of capital stock to amend our Amended and Restated Bylaws, as amended, and certain provisions of our charter.

In addition, we have not opted out of the provisions of Section 203 of the Delaware General Corporation Law (the "DGCL"), which generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with any "interested" stockholder for a period of three years following the date on which the stockholder became an "interested" stockholder.

These provisions may frustrate or prevent any attempts by stockholders to replace or remove the Company's management by making it more difficult for stockholders to replace members of the Board of Directors, which is responsible for appointing the members of our management. In addition, institutional stockholder representative groups, stockholder activists, and others may disagree with our corporate governance provisions or other practices, including anti-takeover provisions, such as those listed above. We generally will consider recommendations of institutional stockholder representative groups, but we will make decisions based on what our Board and management believe to be in the best long-term interests of the Company and stockholders; however, these groups could make recommendations to our stockholders against our practices or our Board members if they disagree with our positions.

These and other provisions in our charter and Amended and Restated Bylaws, as amended, and under Delaware law could discourage potential takeover attempts, reduce the price investors might be willing to pay in the future for shares of Class A common stock and result in the market price of Class A common stock being lower than it would be without these provisions.

***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.***

Our Second Amended and Restated Certificate of Incorporation, as amended, provides, to the fullest extent permitted by law, that unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will be the exclusive forum for the following types of actions or proceedings under Delaware statutory or common law:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any derivative action or proceeding brought on behalf of the Company;

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any action or proceeding asserting a claim of breach of a fiduciary duty owed by or any wrongdoing by any current or former director, officer, employee, or agent of the Company or any stockholder to the Company or to stockholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any action or proceeding asserting a claim against us or any current or former director, officer, or other employee or any stockholder in such stockholder's capacity as such arising out of or pursuant to any provision of the DGCL, our Second Amended and Restated Certificate of Incorporation, as amended, or our Amended and Restated Bylaws, as amended;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any action or proceeding to interpret, apply, enforce or determine the validity of our Second Amended and Restated Certificate of Incorporation, as amended, and/or our Amended and Restated Bylaws, as amended (including any right, obligation or remedy thereunder);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any action or proceeding as to which the DGCL confers jurisdiction to the Court of Chancery of the State of Delaware; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any action or proceeding asserting a claim governed by the internal affairs doctrine, in all cases to the fullest extent permitted by law and subject to the court's having personal jurisdiction over the indispensable parties named as defendants.

Our Second Amended and Restated Certificate of Incorporation, as amended, also 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 the Company or our directors, officers, employees, or stockholders. If any other court of competent jurisdiction were to find either exclusive-forum provision in our Second Amended and Restated Certificate of Incorporation, as amended, to be inapplicable or unenforceable, we may incur additional costs associated with resolving the dispute in other jurisdictions, which could adversely affect our business, financial condition and results of operations. In addition, although the Delaware Supreme Court ruled in March 2020 that federal forum selection provisions purporting to require claims under the Securities Act be brought in federal court were "facially valid" under Delaware law, there is uncertainty as to whether other courts will enforce our federal forum selection clause.

***Future sales and issuances of our Class A common stock could cause our stock price to fall.***

Sales of a substantial number of shares of Class A common stock by our existing stockholders in the public market, or the perception that these sales might occur, could depress the market price of our Class A common stock and could impair our ability to raise additional capital through the issuance of additional equity securities. We are unable to predict the effect that such sales may have on the prevailing market price of our Class A common stock.

Any issuance of equity we may undertake in the future to raise additional capital could cause the price of our Class A common stock to decline, or require us to issue shares at a price that is lower than that paid by holders of our Class A common stock in the past, which would result in those newly issued shares being dilutive. In addition, future investors could gain rights superior to existing stockholders, such as liquidation and other preferences. If we obtain funds through a credit facility or through the issuance of debt or preferred securities, these securities will likely have rights senior to the rights of a common stockholder, which could impair the value of our Class A common stock.

We also have stock options and warrants outstanding to purchase shares of our capital stock. Our stockholders may incur dilution upon exercise of any outstanding stock options and warrants.

***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 adopted an ATM program in September 2025. From the adoption of the ATM until December 31, 2025, we issued 757,193 shares under this program to raise approximately $13.6 million. In September 2025, we entered into an ELOC with an investor. As of December 31, 2025, we have not issued any shares under the ELOC but we anticipate utilizing the ELOC in the future. The sale of shares under these arrangements could dilute existing

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

stockholders, depress the market price of our Class A common stock, increase volatility, and reduce our ability to raise capital on favorable terms.

In addition, we might sell shares under our ELOC to raise capital in the future. Under the ELOC, we have the right to sell shares of our Class A common stock to raise up to $50.0 million of potential proceeds, subject to the satisfaction of customary conditions. Under the ELOC, when we deliver a put notice, the purchase price for shares sold to the counterparty is calculated at a 6% discount to the lowest volume-weighted average price ("VWAP") of our Class A common stock during the three trading-day period beginning on the date we submit the put notice. We are also required to pay a fee to our investment bank in connection with transactions under the ELOC. Because the purchase price is tied to market prices during a short measurement period and incorporates a discount, the effective price at which we sell shares could be significantly below the market price at the time these sales are settled.

Sales under the ELOC could adversely affect the market price of our Class A common stock. The counterparty will likely resell shares it purchases under the ELOC into the public market, and such resales could contribute to downward pressure on our stock price. Although the ELOC restricts the counterparty from hedging or short selling in connection with the facility, these restrictions may not prevent declines in the market price of our Class A common stock resulting from dilution from our share issuances, the counterparty's resales of shares acquired under the ELOC, increased supply of shares in the market generally, or investor perception that we may continue to access the ELOC.

If we are unable to obtain sufficient funding through the ATM or the ELOC, we may be required to seek additional financing, which may not be available on favorable terms, or at all, and could materially and adversely affect our business, financial condition, and results of operations.

Accordingly, our equity financing arrangements, and our use of them, could materially and adversely affect the trading price of our Class A common stock, result in significant dilution to existing stockholders, and limit our ability to finance our operations and strategic objectives.

***We need additional capital and any additional capital we seek may not be available in the amount or at the time we need it.***

We need to raise funds in the future to execute our business plan. We may seek to raise additional capital to expand our business, pursue strategic investments, and take advantage of financing or other opportunities that we believe to be in our best interests and the interests of our stockholders. Additional capital may be raised through the sale of common or preferred equity or convertible debt securities, entry into debt facilities or other third-party funding arrangements. The sale of equity and convertible debt securities may result in dilution to our stockholders and those securities may have rights senior to those of our Class A common stock. Agreements entered into in connection with such capital raising activities could contain covenants that would restrict our operations or require us to relinquish certain rights. Additional capital may not be available on reasonable terms, or at all. If we cannot timely raise any needed funds, we may be forced to reduce our operating expenses, which could adversely affect our ability to implement our long-term strategic roadmap and grow our business. Our ability to raise capital through the sale of securities may be limited by our inability to utilize a Registration Statement on Form S-3 to raise capital until November 2026 due to the late filing of our Quarterly Report on Form 10-Q dated November 20, 2025.

***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.***

The publicly traded shares of our Class A common stock have experienced, and may experience in the future, significant price and volume fluctuations. During the 12 months ended March 24, 2026, the market price of our Class A common stock has ranged from a high of $43.57 per share to a low of $3.82 per share on a split-adjusted basis. This market volatility could reduce the market price of our Class A common stock without regard to our operating performance. In addition, the trading price of our Class A common stock could change significantly in response to actual or anticipated variations in our quarterly operating results, announcements by us or our competitors, factors affecting the space transportation industry generally, changes in national or regional economic conditions, changes in securities analysts' estimates for us or our competitors' or industry's future performance or general market conditions, making it more difficult for shares of our Class A common stock to be sold at a favorable price or at all. The market price of our Class A common stock could also be reduced by general market price declines or market volatility in the future or future declines or volatility in the prices of stocks for companies in our industry.

**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.***

We are exposed to the risk that our employees and independent contractors may engage in misconduct or other illegal activity. Misconduct by these parties could include intentional, reckless or negligent conduct or other activities that violate U.S. and international laws and regulations. It is not always possible to identify and deter misconduct by employees and other third parties, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. In addition, we are subject to the risk that a person or government could allege such fraud or other misconduct, even if none occurred. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, prospects, financial condition, and operating results, including, without limitation, the imposition of significant civil, criminal and administrative penalties, damages, monetary fines, disgorgement, integrity oversight and reporting obligations to resolve allegations of non-compliance, imprisonment, other sanctions, contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which could have a material adverse effect on our business, financial condition, and results of operations.

***Labor-related matters, including labor disputes, may adversely affect our operations.***

Momentus relies on its employees in the day-to-day operations of its business. Actual or threatened labor disputes may disrupt our operations and adversely affect our ability to operate as a business. Such labor disputes and disruptions may result in the loss of market share to competitors and/or have a negative impact on the Company's brand and corporate image.

**Overview**

Momentus offers or plans to offer satellites, satellite buses, satellite technologies and components, including solar arrays, and transportation, communications and infrastructure services for commercial companies and to support the missions of U.S. and friendly governments. Government and commercial satellite operators and space technology companies and organizations are our target commercial customers. Momentus is also seeking business in support of U.S. government missions for departments and agencies like NASA and the U.S Department of Defense.

We provide or plan to provide satellites, satellite buses, satellite technologies and components, including solar arrays, 3D printed propulsion tanks, integration of payload instruments, communication, tracking, and other satellite services, "last mile" satellite transportation, payload-hosting, on-orbit satellite refueling, on-orbit inspection, on-orbit satellite maintenance, de-orbiting, debris removal, and other satellite-to-satellite service offerings.

Our transportation service offering focuses on delivering our customers' satellites to precision orbits. To accomplish this, we partner with leading launch service providers, such as SpaceX, to "ride share" our customers' satellites from Earth to space on a midsized or large rocket. Customer satellites can also be carried aboard small launch vehicles for dedicated missions. Our OSVs would then provide "last mile" transportation services from the rocket's drop-off orbit to a custom orbit of the satellite operator's choosing. We believe this "hub-and-spoke" model has the potential to expand our customers' deployment options relative to what they would be able to achieve with ride share launch alone, while reducing their costs relative to what they could achieve with a dedicated small launch vehicle. Over time, we plan to begin introducing additional services beyond transportation and hosted payloads.

Our services are made possible by the space industry's rapid technological developments over the past two decades, driven predominantly by significant decreases in launch costs, as well as the advent of smaller, lower-cost satellites. The convergence of these trends has resulted in substantial growth in the commercial space market, rooted in higher accessibility for companies entering the new space economy that aim to offer communication, sensing, data processing and storage, Earth observation and data collection services, and other satellite services.

We anticipate potential considerable growth over the coming years in the space transportation segment as companies continue to seek versatile and low-cost ways to deliver single satellites to specific orbits or deploy their satellite constellations. We anticipate that the need for small satellite transportation to low-Earth orbit will continue to drive overall demand growth for space transportation services in the short-term as technology advancements continue to make space more accessible to new market entrants, although new applications beyond low-Earth orbit are also

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

emerging. We also believe that over the next decade, new space-based businesses may emerge, for example the generation of solar energy in space, space manufacturing or space data processing. The advent of these new business models could substantially increase demand for space transportation and other space infrastructure services.

Beyond transportation, we anticipate that growth of the satellite constellations market may drive demand for our satellites, satellites buses, and technologies like solar arrays, 3D printed propulsion tanks, hosted payload, communication, tracking, and other satellite services, on-orbit satellite refueling, on-orbit inspection, on-orbit satellite maintenance, de-orbiting, debris removal, and other satellite-to-satellite service offerings, if we are successful in executing on our business plan, including fully developing and validating our technology in space. Satellite constellations have relatively low lifespans and, in our view, will require maintenance, de-orbiting, and other general servicing with higher frequency.

Momentus offers the M-1000 satellite bus to both commercial and U.S. government customers. The market for satellite buses in this class is substantial and growing. The M-1000 satellite bus is based on the Vigoride OSV and has substantial commonality.

Momentus has launched four missions to date, deployed 17 customer satellites, and provided hosted payload services. Three of these missions involved operation of the Vigoride OSV in orbit. During these three Vigoride missions, the system and technology were tested repeatedly. Improvements based on lessons learned during these missions were rapidly incorporated. As a result of these three missions, the Vigoride OSV has been successfully demonstrated in space and accumulated significant flight heritage.

**Components of Results of Operations**

***Service Revenue***

We enter into contracts for 'last-mile' satellite and cargo delivery, payload hosting and in-orbit servicing options with customers that are primarily in the aerospace industry. The Company recognizes revenue (along with any other fees that have been paid) upon the earlier of the satisfaction of our performance obligation or when the customer cancels the contract. The Company also enters into contracts to perform analysis and provide engineering services to U.S. government organizations.

In general, our customers have the right to cancel their contracts with the understanding that they will forgo their deposits. If a customer cancels a contract before it is required to pay non-refundable deposits, we may not receive revenue from these orders, except for an initial deposit which is paid at the time the contract is signed.

During the year ended December 31, 2025, the Company recognized $1.1 million of revenue primarily from the completion of performance obligations on engineering services performed for U.S. government and engineering project services.

As of December 31, 2025, the Company had signed contracts with customers and had collected approximately $4.2 million in customer deposits, $0.1 million of which are recorded as non-current contract liabilities in our consolidated balance sheets.

The Company estimates variable consideration at the most likely amount, which is included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur. While the Company's standard contracts do not contain refund or recourse provisions that enable its customers to recover any non-refundable fees that have been paid, the Company may issue full or partial refunds to customers on a case-by-case basis as necessary to preserve and foster future business relationships and customer goodwill. Contracts to provide engineering services to U.S. government organizations generally have milestone payments subject to the variable consideration constraint. When a milestone is achieved, the Company updates its estimate of the transaction price to include the milestone payment and records a cumulative catch-up in revenue.

***Cost of Revenue***

Cost of revenue consists primarily of expenses associated with third-party launch costs and direct headcount related to the related engineering work. The costs associated with OSVs are deferred to prepaid cost of revenues and amortized to cost of revenues upon release of payload. The current design and technology allow for a single use of the OSV.

***Research and Development***

Research and development expenditures consist primarily of the cost of the following activities for developing existing and future technologies for our satellites, satellite technologies, and our OSV. Research and development

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

activities include basic research, applied research, design, development, and related test program activities. Costs incurred for developing our technologies primarily include equipment and labor hours (both internal and subcontractors). The Company also records launch costs related to the testing of its Vigoride vehicles as research and development costs.

As of December 31, 2025, we have expensed all research and development costs associated with developing and building our vehicles.

***Selling, General and Administrative***

Selling, general and administrative expenses consist of human capital related expenses for employees involved in general corporate functions, including executive management and administration, accounting, finance, tax, legal, information technology, security, sales, marketing, and human resources; depreciation expense and rent relating to facilities, and equipment; professional fees; and other general corporate costs. Headcount-related expenses primarily include salaries, bonuses, equity compensation expense and benefits.

We also incur additional expenses as a result of operating as a public company, including expenses necessary to comply with the rules and regulations applicable to companies listed on a national securities exchange and related to compliance and reporting obligations pursuant to the rules and regulations of the SEC.

***Realized loss on disposal of assets***

Realized loss on disposal of assets consists of disposals of machinery and equipment with carrying values in excess of proceeds received, if any.

***Interest Income***

Interest income consists of interest earned by the Company on investment holdings in interest bearing bank accounts.

***Interest Expense***

Interest expense includes interest incurred by the Company related to our loan payables as well as the amortization of warrant discount and debt issuance costs.

***Gain (Loss) on Debt Extinguishment***

Gains or losses on extinguishment of debt are recognized for unamortized debt premiums, discounts and issuance costs as well as any fees paid to the lender in relation to the extinguishment.

***Change in Fair Value of Convertible Debt Carried at Fair Value***

Changes in the fair value of convertible debt measured at fair value on a recurring basis.

***Change in Fair Value of Warrant Liability***

Changes in the fair value of warrant liabilities measured at fair value on a recurring basis.

***Other Income (Expense)***

Other income (expense) primarily relates to non-recurring fees incurred in conjunction with impairment or write-off charges, the Term Loan financing, SEC settlement cost, and other immaterial items.

***Income Tax Provision***

We are subject to income taxes in the United States. Our income tax provision consists of an estimate of federal and state income taxes based on enacted federal and state tax rates, as adjusted for allowable credits, deductions, uncertain tax positions, changes in the valuation of our deferred tax assets and liabilities, and changes in tax laws.

The effective tax rate may vary significantly from period to period and can be influenced by many factors. These factors include, but are not limited to, changes to the statutory rates in the jurisdictions where the Company has operations and changes in the valuation of deferred tax assets and liabilities. The difference between the effective tax rate and the federal statutory rate of 21% primarily relates to certain nondeductible items, state and local income taxes and a full valuation allowance for deferred tax assets.

***Service revenue***

Revenue recognized during both the years ended December 31, 2025 and 2024, was primarily the result of engineering services performed under the Defense Advanced Research Project Agency ("DARPA") Novel Orbital and Moon Manufacturing, Materials, and Mass-efficient Design ("NOM4D") and DARPA Bringing Classified Innovation to Defense and Government Systems ("BRIDGES") programs and the Space Development Agency Hybrid Acquisition for Proliferated Low Earth Orbit ("HALO") program. Of $1.1 million and $2.1 million of revenue recognized during the years ended December 31, 2025 and 2024, respectively, $0.9 million and $1.8 million, respectively, were recognized for engineering services performed. The remaining $0.2 million and $0.3 million of revenue recognized during the years ended December 31, 2025 and 2024, respectively, was due to the forfeiture of customer deposits upon contract expiration.

***Cost of revenue***

Cost of revenue for the years ended December 31, 2025 and 2024, consisted primarily of personnel costs for engineering services under our agreement with the Space Development Agency, including salaries, benefits, and other direct labor-related expenses.

***Research and development expenses***

Research and development expenses decreased from $9.8 million in the year ended December 31, 2024, to $9.2 million in the year ended December 31, 2025. The decrease was primarily due to a $1.1 million reduction in payroll costs due to decreased headcount, partially offset by a $0.4 million increase in subcontractor costs and a $0.1 million increase in other miscellaneous fees, such as information technology and facilities overhead allocation.

***Selling, general and administrative expenses***

Selling, general and administrative expenses decreased from $21.9 million in the year ended December 31, 2024, to $19.2 million in the year ended December 31, 2025. The decrease is primarily due to (i) a $4.1 million decrease in

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

payroll related expenses, inclusive of a decrease of $3.1 million in non-cash stock-based compensation, (ii) a decrease in legal expenses of $0.8 million, and (iii) a $0.9 million decrease in other miscellaneous fees, such as insurance and subscriptions. These decreases were partially offset by an increase in consulting and professional services of $1.4 million and a $1.7 million impairment of prepaid services (see Note 9 for additional information).

***Realized loss on disposal of assets***

The decrease in realized loss on disposal of assets for the year ended December 31, 2024, was due to losses from the auction of machinery and equipment. There was no loss on disposal recognized during the year ended December 31, 2025.

***Interest income***

Interest income increased from $0.03 million for year ended December 31, 2024, to $0.1 million for the year ended December 31, 2025, as the Company invested more in money market funds.

***Interest expense***

Interest expense increased from $0.4 million for the year ended December 31, 2024, to $0.7 million for the year ended December 31, 2025. The interest increase is primarily due to increase in cash interest accrual and amortization of the debt discount on the SIV Convertible Notes and the September 2025 Convertible Note, partially offset by amortization of the debt premium on the SIV Convertible Notes. See Note 8 for additional information.

***Loss on debt extinguishment***

The loss on extinguishment of debt of $2.8 million recognized for the year ended December 31, 2025, was due to the amendment of the SIV Convertible Notes and extinguishment of the May 2025 Loan. The loss on extinguishment of debt of $4.3 million recognized for the year ended December 31, 2024, was due to the early payoff of the December 2024 Loan and amendment of the SIV Convertible Notes. See Note 8 for additional information.

***Change in fair value of convertible debt carried at fair value***

The change in fair value of convertible debt carried at fair value for the year ended December 31, 2025, was due to the change in fair value of the May 2025 Loan. See the Fair Value Measurement discussion in Note 2 for additional information.

***Change in fair value of warrant liability***

The change in fair value of warrant liability for the year ended December 31, 2025, was due to the change in fair value of the AIR Warrants and the ELOC Pre-funded Warrants. See the Fair Value Measurement discussion in Note 2 for additional information.

***Other income (expense)***

Other expense increased to $1.3 million during the year ended December 31, 2025, primarily due to the $1.4 million loss recognized on issuance of warrant liabilities related to the September 2025 Private Placement (see Note 8 for additional information) partially offset by a $0.2 million change in fair value of derivatives.

**Liquidity and Capital Resources**

***Going Concern***

In connection with the preparation of the consolidated financial statements for the year ended December 31, 2025, management concluded that, in the event the Company is unable to raise additional financing, the following plans alleviate the substantial doubt about the Company's ability to continue as a going concern within twelve months after the date of the issuance of such financial statements: (i) collection of amounts as they come due under customer contracts, (ii) monetization of unutilized capacity under the MSA agreement with Velo3D; (iii) reduction of employee headcount and compensation expenses; and (iv) reduction of outside vendor expenses.

While the Company believes these actions provide sufficient liquidity for its current operating plans, additional capital will be required in the future to support operations and growth initiatives and achieve profitability, and there can be no assurance that such capital will be available on acceptable terms or at all. The Company's ability to continue as a going concern is dependent on the Company's ability to successfully raise capital to fund its business operations and execute on its business plan. To date, the Company has not generated sufficient revenues to provide cash flows that enable the Company to finance its operations internally. This is reflected by the Company's incurred net losses of $30.5 million for the year ended December 31, 2025, and an accumulated deficit of $438.6 million as of

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

December 31, 2025. Additionally, the Company used net cash of $23.3 million to fund its operating activities for the year ended December 31, 2025, and had cash and cash equivalents of $12.8 million as of December 31, 2025.

The accompanying consolidated financial statements have been prepared on a going concern basis of accounting. The accompanying consolidated financial statements do not reflect any adjustments that might result if the Company is unable to continue as a going concern.

***Operating Activities***

Net cash used in operating activities for the year ended December 31, 2025, was $23.3 million, consisting primarily of headcount costs, research and development activities, legal expenses, and professional fees, as well as net cash changes in operating assets and liabilities.

Headcount related payroll costs, excluding stock-based compensation of $3.3 million, were $7.1 million. Professional fees of $7.0 million included $2.3 million in legal fees. Office overheads and other general corporate expenses were $5.5 million, which includes insurance costs of $1.0 million. Research and Development activity expenses, including materials, components, and subcontractor costs were $2.1 million. These cash outflows were partially offset by gross profit of $1.1 million primarily related to the fulfillment of performance obligations during the year ended December 31, 2025. Additionally, the Company had a change in operating assets and liabilities of $2.7 million during the year ended December 31, 2025.

Net cash used in operating activities for the year ended December 31, 2024, was $16.6 million, driven primarily by headcount costs, research and development activities, legal expenses, and professional fees, as well as net cash changes in operating assets and liabilities.

Headcount related payroll costs, excluding stock-based compensation of $6.5 million, were $9.0 million. Professional fees of $6.7 million included $3.1 million in legal fees. Office overheads and other general corporate expenses were $5.8 million, which includes insurance costs of $1.5 million. Research and Development activity expenses, including materials, components, and subcontractor costs were $1.7 million. These cash outflows were partially offset by gross profit of $2.0 million primarily related to the fulfillment of performance obligations for Vigoride 5 and Vigoride 6 customers during the year ended December 31, 2024. Additionally, the Company had a change in operating assets and liabilities of $5.2 million during the year ended December 31, 2024.

Net cash provided by investing activities was $0.1 million for the year ended December 31, 2024, which consisted of proceeds received on the sale of machinery and equipment.

***Financing Activities***

Net cash provided by financing activities was $34.6 million for the year ended December 31, 2025, primarily due to gross proceeds of approximately (i) $22.6 million received from the July 2025 Offering and February 2025 Offering, (ii) $15.6 million received from the December 2025 Warrant Inducement, October 2025 Warrant Inducement, August 2025 Warrant Inducement, and March 2025 Warrant Inducement, and (iii) $2.3 million received from the September 2025 Private Placement, the May 2025 Loan, and related issuances of warrants. These gross proceeds were partially offset by principal repayments of $2.2 million on the May 2025 Loan and SIV Convertible Notes and $3.7 million in issuance costs related to convertible notes, common stock, related warrants, the warrant inducements, and other common and preferred stock issuances.

Net cash provided by financing activities was $15.6 million for the year ended December 31, 2024, primarily due to gross proceeds of approximately (i) $15.7 million received from the December 2024 Offering, September 2024

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

Offering, March 2024 Offering, and January 2024 Offering, (ii) $5.3 million received from the SIV Convertible Notes, and (iii) $2.0 million from the December 2024 Loan. These gross proceeds were partially offset by (i) principal repayments of $4.7 million under the Term Loan, (ii) $2.1 million in issuance costs related to convertible notes, common stock and related warrants, and (iii) principal repayments of $0.6 million under the SIV Convertible Notes.

***Funding Requirements***

We expect our cash consumption to continue in connection with our ongoing activities.

Specifically, our operating expenses will continue as we:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• continue to refine and operate our corporate infrastructure, people, processes and systems;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• pursue sales and marketing activities for our product and services;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• pursue further research and development related to developing our satellites and satellite technology;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• seek regulatory approvals for operation of our satellites and vehicles;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• actively manage our workforce, including right sizing in personnel;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• maintain, expand and protect our intellectual property portfolio;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• comply with public company reporting requirements; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• defend against litigation.

Changing circumstances may cause us to expend capital significantly faster than we currently anticipate, or we may need to spend more money than currently expected because of circumstances beyond our control. We may be required to seek additional equity or debt financing. In the event that additional financing is required from outside sources, we may not be able to raise it on terms acceptable to us, or at all. If we are unable to raise additional capital when desired, our business, results of operations, and financial condition would be adversely affected.

**Commitments and Contingencies**

We are a party to leases primarily for facilities (e.g., office buildings, warehouses, and spaceport) under non-cancellable operating leases. Refer to Note 6.

We enter into purchase obligations in the normal course of business. These obligations include purchase orders and agreements to purchase goods or services that are enforceable, legally binding, and have significant terms and minimum purchases stipulated. Refer to Note 12.

In addition, we enter into agreements in the normal course of business with vendors for research and development services and outsourced services, which are generally cancellable upon written notice.

**Off-Balance Sheet Arrangements**

We do not engage in any off-balance sheet activities or have any arrangements or relationships with unconsolidated entities, such as variable interest, special purpose, and structured finance entities.

**Critical Accounting Policies and Estimates**

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of our consolidated financial statements and related disclosures requires us to make estimates, assumptions and judgments as of the balance sheet date that affect the reported amounts of assets, liabilities, revenues, costs and expenses and related disclosures. Our actual results may differ from these estimates under different assumptions and conditions. In addition to our critical accounting policies below, see Note 2 in the notes to our consolidated financial statements included elsewhere in this Form 10-K.

***Revenue Recognition***

The Company enters into short-term contracts for 'last-mile' satellite and cargo delivery (transportation services), payload hosting and in-orbit servicing options with customers that are primarily in the aerospace industry. For its transportation service arrangements, the Company has a performance obligation of delivering the customers' payload to its designated orbit and recognizes revenue (along with any other fees that have been paid) at a point in

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

time, upon satisfaction of this performance obligation. Additionally, for its in-orbit service arrangements, the Company provides a multitude of services during the mission to its customers. The Company recognizes revenue for these in-orbit services ratably over time on a straight-line basis. The Company enters into contracts to perform services for U.S. government customers. The Company recognizes revenue for these services in accordance with the terms of these contracts.

We account for customer contracts in accordance with ASC Topic 606, which includes the following five-step model:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Identification of the contract, or contracts, with a customer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Identification of the performance obligations in the contract.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Determination of the transaction price.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Allocation of the transaction price to the performance obligations in the contract.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Recognition of revenue when, or as, the Company satisfies a performance obligation.

The Company estimates variable consideration at the most likely amount, which is included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur. While the Company's standard contracts do not contain refund or recourse provisions that enable its customers to recover any non-refundable fees that have been paid, the Company may issue full or partial refunds, or concessions on future services to customers on a case-by-case basis as necessary to preserve and foster future business relationships and customer goodwill.

The Company's satellite and cargo delivery services (transportation services) are considered a performance obligation, to transport the customers' payload to a specified orbit in space. We recognize revenue for these services at a point in time, when control is transferred, which is considered to be upon the release of the customers' payload into its specified orbit. We will calculate the weight distribution of each transfer vehicle at the customer level, and we will estimate the delivery date for each customer's payload based on the relative weight of payloads released to determine the point in time to recognize revenue for each payload release.

The Company's in-orbit services consist of a collection of interdependent and integrated services which are not considered distinct from one another and may vary depending on the specific needs of the Customer and mission. Revenue for these in-orbit services is recognized ratably over time on a straight line basis.

The Company's engineering project services to U.S. government organizations generally have specific payment attached to each milestone. When a milestone is achieved, the Company submits services performed for approval. Once approval is received, the Company invoices and collects on the milestone completed.

In periods in which we recognize revenue, we will disclose the amounts of revenue recognized that was included as a contract liability balance at the beginning of the reporting period in accordance with ASC Sub-Topic 606-10-50-8(b).

***Loss Contingencies***

We are subject to the possibility of various loss contingencies arising in the ordinary course of business, including product-related and other litigation. We consider the likelihood of loss or impairment of an asset or the incurrence of a liability, as well as our ability to reasonably estimate the amount of loss in determining loss contingencies. An estimated loss contingency is accrued when it is probable that an asset has been impaired or a liability has been incurred and the amount of loss can be reasonably estimated. We regularly evaluate current information available to us to determine whether such accruals should be adjusted and whether new accruals are required. Refer to Note 12.

***Deferred Fulfillment and Prepaid Launch Costs***

We prepay for certain launch costs to third-party providers that will carry the OSV or satellite to orbit. Prepaid costs allocated to the delivery of a customer's payload are classified as deferred fulfillment costs. Prepaid costs allocated to our payload are classified as prepaid launch costs. These costs are then recognized as cost of revenues upon release of the customer's payload and our payload, respectively.

***Contract Liabilities***

Customer deposits collected prior to the release of the customer's payload into its specified orbit are recorded as current and non-current contract liabilities in our consolidated balance sheets as the amounts received represent a prepayment for the satisfaction of a future performance obligation that has not yet commenced. Some customer

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

deposits are non-refundable. Each non-refundable deposit is determined to be a contract liability upon cash collection. Prior to making this determination, we ensure that a valid contract is in place that meets the definition of the existence of a contract in accordance with ASC Sub-Topic 606-10-25-1 and 2.

***Stock-based Compensation***

We have various stock incentive plans under which incentive and NSOs and RSAs are granted to employees, directors, and consultants. All stock-based payments to employees, including grants of employee stock options are recognized in the consolidated financial statements based on their respective grant date fair values.

We recognize stock-based compensation expense using a fair value-based method for costs related to all stock-based payments. We estimate the fair value of stock-based payments on the date of grant using the Black-Scholes-Merton option pricing model (or "BSM"). The model requires management to make a number of assumptions, including expected volatility of our stock, expected life of the option, risk-free interest rate, and expected dividends. The fair value of the stock is expensed over the related service period which is typically the vesting period. The stock-based compensation expense that is reported in our consolidated financial statements is based on awards that are expected to vest. We account for forfeitures as they occur.

Estimating the fair value of equity awards as of the grant date using valuation models, such as the BSM option pricing model, is affected by assumptions regarding a number of variables as disclosed above, and any changes in the assumptions can materially affect the fair value and ultimately how much stock-based compensation expense is recognized. These inputs are subjective and generally require significant analysis and judgment to develop.

***Debt and Equity Financings***

We have entered into various debt and equity financing arrangements, including convertible promissory notes, warrants, pre-funded warrants, and an equity line of credit agreement. Accounting for these instruments requires significant management judgment, including the determination of whether warrants and embedded conversion options meet the criteria for equity classification or must be accounted for as liabilities. Certain warrants are accounted for as liabilities and are remeasured at fair value each reporting period using Level 3 valuation techniques, with changes in fair value recognized in the consolidated statements of operations. The fair value calculations involve assumptions regarding stock price volatility, expected term, and risk-free interest rates. Changes in these assumptions could materially affect the Company's financial statements. Refer to Notes 8 and 9 to the consolidated financial statements for additional information.

***Income Taxes***

We account for income taxes in accordance with authoritative guidance, which requires the use of the asset and liability method. Under this method, deferred income tax assets and liabilities are determined based upon the difference between the financial statement carrying amounts and the tax basis of assets and liabilities and are measured using the enacted tax rate expected to apply to taxable income in the years in which the differences are expected to be reversed.

Significant judgment is required in determining any valuation allowance recorded against deferred tax assets. In assessing the need for a valuation allowance, management considers all available evidence, including past operating results, estimates of future taxable income, and the feasibility of tax planning strategies.

In the event that management changes its determination as to the amount of deferred tax assets that can be realized, we will adjust our valuation allowance with a corresponding impact to the provision for income taxes in the period in which such determination is made.

ASC Topic 740-10 requires companies to determine whether it is "more likely than not" that a tax position will be sustained upon examination by the appropriate taxing authorities before any tax benefit can be recorded in the consolidated financial statements. It also provides guidance on the recognition, measurement, classification and interest and penalties related to uncertain tax positions. The amount that is ultimately sustained for an individual uncertain tax position or for all uncertain tax positions in the aggregate could differ from the amount that is initially recognized.

**Recent Accounting Pronouncements**

From time to time, new accounting pronouncements are issued by the FASB or other standard-setting bodies that are adopted by us as of the specified effective date. Unless otherwise discussed, we believe that the impact of recently issued standards that are not yet effective will not have a material impact on our financial position or results of operations upon adoption.

------

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

Please refer to Note 2 in the notes to our consolidated financial statements included elsewhere in this Form 10-K for a description of recently adopted accounting pronouncements and recently issued accounting pronouncements not yet adopted, the timing of their adoptions and our assessment, to the extent we have made one, of their potential impact on our consolidated financial condition and results of operations.

**ITEM 7A. Quantitative and Qualitative Disclosures about Market Risk**

We are exposed to a variety of market and other risks, including the effects of changes in interest rates, and inflation, as well as risks to the availability of funding sources, hazard events, and specific asset risks.

*Interest Rate Risk*

The market risk inherent in our financial instruments and our financial position represents the potential loss arising from adverse changes in interest rates. As of December 31, 2025, we had cash and cash equivalents of $12.8 million, which were primarily invested in highly liquid investments purchased with a remaining maturity of three months or less. However, due to the short-term maturities and the low-risk profile of our investments, an immediate 10% change in interest rates would not have a material effect on the fair value of our cash and cash equivalents.

*Foreign Currency Risk*

There were no material foreign currency transactions for the years ended December 31, 2025 and 2024.

**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

To the Board of Directors and Stockholders of

Momentus Inc.

**Opinion on the Consolidated Financial Statements**

We have audited the accompanying consolidated balance sheets of Momentus Inc. and Subsidiaries (collectively the "Company") as of December 31, 2025 and 2024, and the related consolidated statements of operations, stockholders' equity (deficit), and cash flows, for the years then ended, and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

**Basis for Opinion**

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (the "PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the U.S. Securities and Exchange Commission (the "SEC") and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

**Critical Audit Matters**

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

***Amendments of Convertible Notes – Refer to Note 8 in the Consolidated Financial Statements***

As discussed in Note 8, the Company entered into multiple amendments to its existing convertible debt agreements with Space Infrastructure Ventures (the "Convertible Notes"). Management evaluated each amendment to determine whether it should be accounted for as a debt modification or a debt extinguishment. This process involved significant management judgment in determining the appropriate accounting treatment and required a complex analysis of the terms of the amended agreements compared to the original agreements. For amendments determined to represent extinguishments, the Company recognized a gain or loss on extinguishment, as applicable, resulting in a net loss on debt extinguishment.

We identified the accounting for the amended convertible debt as a critical audit matter due to the significant judgments required by management in assessing whether the terms of the amended agreements were substantially different from the original agreements, which impacted whether the transactions were accounted for as modifications or extinguishments. This involved significant audit effort and the use of auditor judgment when performing audit procedures and evaluating the results of those procedures.

<u>[**Table of Contents**](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

*How the Critical Audit Matter Was Addressed in the Audit*

Our principal audit procedures performed to address this critical audit matter included the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We obtained an understanding and evaluated the design and implementation of controls over the Company's accounting for the amendments of the Convertible Notes, including management's review controls over the technical accounting aspects of the amendments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We read the underlying agreements and assessed the terms in relation to the relevant accounting principles.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We tested the completeness and accuracy of management's analysis over whether each amendment met the conditions to be treated as a debt modification or extinguishment by evaluating them against the relevant technical accounting guidance. This included procedures to evaluate the judgments and estimates that are involved.

***Master Services Agreement with Velo3D, Inc. – Refer to Note 9 in the Consolidated Financial Statements***

As discussed in Note 9, on April 12, 2025, the Company entered into a Master Services Agreement ("MSA") with Velo3D, Inc. ("VLD") pursuant to which the Company issued equity instruments with a grant-date fair value of $10.7 million in exchange for future manufacturing services. In August 2025, the Company irrevocably waived its right under the MSA to cancel shares of the Company's capital stock held by VLD upon expiration or termination of the MSA which made the equity instruments fully vested and non-forfeitable upon amendment. The amendment was accounted for as a Type I Modification under ASC Topic 718 and the Company recognized the grant-date fair value of $10.7 million immediately as a prepaid design and production services asset at the grant-date fair value of the issued equity instruments. As the only term that changed as a result of the amendment was related to vesting, there was no change in the fair value of the equity instruments as a result of the amendment and no incremental fair value was recognized. The MSA also includes a credit provision for unused capacity, which the Company accounted for as an embedded derivative under ASC Topic 815 and records at fair value each reporting period. During the year ended December 31, 2025, the Company recognized a $1.7 million impairment of prepaid design and production services due to underutilization, partially offset by a $0.2 million increase in the fair value of the embedded derivative.

We identified the accounting for the MSA as a critical audit matter due to the significant judgment required by management in (i) determining the appropriate accounting treatment under ASC Topic 718 for equity issued in exchange for services, including the assessment and accounting for the August 2025 modification, (ii) identifying and valuing the embedded derivative under ASC Topic 815, including the determination of key assumptions impacting fair value, and (iii) evaluating the recoverability of the prepaid design and production services asset, including assumptions related to expected utilization of contracted capacity.

*How the Critical Audit Matter Was Addressed in the Audit*

Our principal audit procedures performed to address this critical audit matter included the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We obtained an understanding and evaluated the design and implementation of controls over the Company's accounting for the MSA, including management's review controls over the technical accounting aspects of the transaction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We read the underlying agreements and assessed the terms in relation to the relevant accounting principles.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We tested the completeness and accuracy of management's analyses over (i) the grant-date fair value measurement of the equity instruments, (ii) the embedded derivative identification and related fair value measurements, (iii) the modification event and related incremental fair value assessment, (iv) the resulting asset recognition, and (v) the subsequent partial impairment by evaluating the analyses against the relevant technical accounting guidance. This included procedures to evaluate the judgments and estimates that are involved.

<u>[Tables of Contents](#i9fca5dae47184b068dbf486a3d8088f4_13)</u>

**MOMENTUS INC.**

**NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS**

**Note 1. Nature of Operations**

***The Company***

Momentus Inc. (together with its consolidated subsidiaries "Momentus" or the "Company") is a U.S. commercial space company that offers satellites, satellite buses, satellite technologies and components, and space infrastructure services, including in-space transportation, hosted payloads and in-orbit services.

Momentus has launched four missions to date, deployed 17 customer satellites, and provided hosted payload services. Three of these missions involved operation of the Vigoride Orbital Service Vehicle ("OSV") in orbit. During these three Vigoride missions, the system and technology were tested repeatedly. Improvements based on lessons learned during these missions were rapidly incorporated. As a result of these three missions, the Vigoride OSV has been successfully demonstrated in space and accumulated significant flight heritage. The Company has produced its next OSV, Vigoride 7, that it intends to utilize on a 2026 mission.

In addition to the Vigoride OSV, Momentus is now also offering its M-1000 satellite bus which has substantial commonality with Vigoride. With a growing demand for satellite bus services, Momentus is positioned to advance its hardware and flight-proven technology for this market. The M-1000 bus is a flexible option to meet various mission requirements. Innovations to improve sensor capability, maneuverability, increased power, and lower costs are integrated into the product. Momentus believes it can manufacture satellite buses like the M-1000 at a rapid and scalable pace.

***Business Combination***

On August 12, 2021, the Company consummated a merger pursuant to the terms of the Agreement and Plan of Merger, dated October 7, 2020, and as amended on March 5, 2021, April 6, 2021, and June 29, 2021 (the "Merger Agreement"), by and among Stable Road Acquisition Corp ("SRAC"), Project Marvel First Merger Sub, Inc., a Delaware corporation and a direct, wholly-owned subsidiary of SRAC ("First Merger Sub"), and Project Marvel Second Merger Sub, LLC, a Delaware limited liability company and a direct, wholly-owned subsidiary of SRAC ("Second Merger Sub"), pursuant to which First Merger Sub merged with and into Momentus Inc., a Delaware corporation ("Legacy Momentus") with Legacy Momentus as the surviving corporation of the First Merger Sub, and immediately following which Legacy Momentus merged with and into the Second Merger Sub, with the Second Merger Sub as the surviving entity (the "Business Combination"). In connection with the closing of the Business Combination ("Closing"), the Company changed its name from Stable Road Acquisition Corp. to Momentus Inc., and Legacy Momentus changed its name to Momentus Space, LLC.

The Business Combination was accounted for as a reverse recapitalization under ASC Topic 805, *Business Combinations*, with SRAC and its two wholly-owned subsidiaries. The Company received gross proceeds of $247.3 million upon the Closing. Public and private warrants of SRAC were assumed by the Company as a result of the Business Combination.

***Going Concern***

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. The going concern basis of presentation assumes that the Company will continue in operation one year after the date these consolidated financial statements are issued and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business.

Pursuant to ASC Sub-Topic 205-40, *Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern*, in connection with the preparation of the consolidated financial statements for the year ended December 31, 2025, management concluded that, without taking into consideration the potential mitigating effect of management's plans that have not been fully implemented or are not within control of the Company, there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company's ability to fund its regular operations, scaling of commercial production, and maintain its existing services and products as a going concern for one year from the date these consolidated financial statements are issued. Management's plans in the event the Company is unable to raise additional financing include (i) collection of amounts as they come due under customer contracts, (ii) monetization of unutilized capacity under the MSA agreement with Velo3D; (iii) reduction

**NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS**

**Note 1. Nature of Operations** (cont.)

of employee headcount and compensation expenses; and (iv) reduction of outside vendor expenses. Management then evaluated its plans to reduce expenses under the framework provided in ASC Sub-Topic 205-40, and determined that the mitigating effect of its plans sufficiently alleviates the substantial doubt about the Company's ability to continue as a going concern.

Under ASC Sub-Topic 205-40, the mitigating effect of management's plans is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that the consolidated financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about the Company's ability to continue as a going concern within one year after the date that the consolidated financial statements are issued. While the Company believes these actions provide sufficient liquidity for its current operating plans, additional capital may be required in the future to support growth initiatives and achieve profitability, and there can be no assurance that such capital will be available on acceptable terms or at all. The Company's ability to continue as a going concern is dependent on the Company's ability to successfully raise capital to fund its business operations and execute on its business plan. To date the Company remains heavily focused on growth and continued development of its proprietary technology, and as a result, it has not generated sufficient revenues to provide cash flows that enable the Company to finance its operations internally. This is reflected by the Company's incurred net loss of $30.5 million for the year ended December 31, 2025, and accumulated deficit of $438.6 million as of December 31, 2025. Additionally, the Company used net cash of $23.3 million to fund its operating activities for the year ended December 31, 2025, and had cash and cash equivalents of $12.8 million as of December 31, 2025.

The accompanying consolidated financial statements have been prepared on a going concern basis of accounting. The accompanying consolidated financial statements do not reflect any adjustments that might result if the Company is unable to continue as a going concern.

***Reverse Stock Splits***

Effective December 17, 2025, the Company's stockholders approved a 1-for-17.85 reverse stock split of the Company's Class A common stock. As a result of the reverse stock split, every 17.85 shares of Class A common stock issued and outstanding on December 17, 2025, were automatically combined into one share of Class A common stock. Any fractional shares resulting from the reverse stock split were rounded up to the next nearest whole share of Class A common stock. The reverse stock split did not affect the stated par value of the Class A common stock nor did it change the total number of the Company's authorized shares of Class A common stock. Both the Company's Class B common stock and Series A preferred stock were not affected by the reverse stock split.

In addition to the reverse stock split implemented in December 2025, the Company previously effected a 1-for-14 reverse stock split of the Company's Class A common stock on December 12, 2024, whereby every 14 shares of Class A common stock issued and outstanding on December 12, 2024, were automatically combined into one share of Class A common stock. Any fractional shares resulting from the reverse stock split were rounded up to the next nearest whole share of Class A common stock. The reverse stock split did not affect the stated par value of the Class A common stock nor did it change the total number of the Company's authorized shares of Class A common stock. The Company's Class B common stock were not affected by the reverse stock split.

Also on the effective date of each reverse stock split, all options, warrants, and other convertible securities of the Company outstanding immediately prior to the reverse stock split were adjusted by dividing the number of shares of Class A common stock into which the options, warrants, and other convertible securities are exercisable or convertible by the factor applied in the reverse stock split, and multiplying the exercise or conversion price thereof by the same amount, all in accordance with the terms of the plans, agreements, or arrangements governing such options, warrants, and other convertible securities and subject to rounding to the nearest whole share. Such proportional adjustments were also made to the number of shares and restricted stock units ("RSUs") issued and issuable under the Company's equity compensation plans.

The Company has retroactively adjusted all periods presented for the effects of the December 2025 1-for-17.85 reverse stock split. See Note 9 for additional information.

**NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

**Note 2. Summary of Significant Accounting Policies**

***Principles of Consolidation*** 

The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and balances have been eliminated upon consolidation.

***Use of Estimates***

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Management bases its estimates on historical experience and on various other factors it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Accordingly, actual results could differ from those estimates. Significant estimates inherent in the preparation of the consolidated financial statements include, but are not limited to, the timing of revenue recognition, accounting for useful lives of property, machinery and equipment, net, intangible assets, net, accrued liabilities, leases, income taxes including deferred tax assets and liabilities, impairment valuation, stock-based compensation, warrant liabilities, and litigation contingencies.

***Cash and Cash Equivalents***

Cash and cash equivalents consist of cash on hand, cash in bank with no restrictions, as well as highly liquid investments which are unrestricted as to withdrawal or use, and which have original maturities of three months or less when initially purchased.

The Company places its cash in the bank, which may at times be in excess of the Federal Deposit Insurance Corporation ("FDIC") insurance limits of $250,000 per depositor, with high credit quality financial institutions and attempts to limit the amount of credit exposure with any one institution.

***Restricted Cash***

Restricted cash primarily represents cash deposited as collateral for the Company's credit card program. As of December 31, 2025 and 2024, the Company maintained restricted cash of $0.1 million and zero, respectively.

***Accounts Receivable***

Accounts receivable as of December 31, 2024, represent amounts primarily due from the Defense Advanced Research Project Agency ("DARPA") to provide support to the DARPA Novel Orbital and Moon Manufacturing, Materials, and Mass-efficient Design ("NOM4D") program, including arranging launch services, payload integration, and in-orbit hosting of the payload for a complex in-space assembly mission. Accounts Receivable are stated at invoice value less estimated allowances for credit losses. Allowances are recorded based on the Company's assessment of various factors, such as: historical experience, credit quality of its customers, aging of the accounts receivable balances, economic conditions, and other factors that may affect a customer's ability to pay. The allowance for credit losses as of December 31, 2025 and 2024, was zero.

***Deferred Fulfillment and Prepaid Launch Costs***

The Company prepays for certain launch costs to third-party providers that will carry the transport vehicle to orbit. Prepaid costs allocated to the delivery of a customers' payload are classified as deferred fulfillment costs and prepaid costs allocated to our payload are classified as prepaid launch costs. All deferred fulfillment and prepaid launch costs are recognized as cost of revenue upon delivery of the related payloads.

As of December 31, 2025 and 2024, the Company had deferred fulfillment and prepaid launch costs of $6.3 million and $2.6 million, respectively, with $5.1 million and zero recorded within prepaids and other current assets, respectively, and $1.2 million and $2.6 million recorded within other non-current assets in our consolidated balance sheets, respectively.

**NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS**

**Note 2. Summary of Significant Accounting Policies** (cont.)

***Property, Machinery and Equipment***

Property, machinery and equipment are stated at cost less accumulated depreciation. Depreciation is generally recorded using the straight-line method over the estimated useful lives of the respective assets. The estimated useful lives of fixed assets by asset category are described below:

---

| | |
|:---|:---|
| **Fixed Assets** | **Estimated Useful Life** |
| Computer equipment | Three years |
| Furniture and fixtures | Five years |
| Leasehold improvements | Lesser of estimated useful life or remaining lease term (one year to seven years) |
| Machinery and equipment | Seven years |

---

Costs of maintenance or repairs that do not extend the lives of the respective assets are charged to expenses as incurred.

***Intangible Assets***

Intangible assets, which consist of patents, are considered long-lived assets and are reported at cost less accumulated amortization and accumulated impairment loss, if any. Amortization is recognized on a straight-line basis over 10 years for patents, which is the estimated useful lives of the intangible assets.

In accordance with ASC Sub-Topic 350-40, *Intangibles*, the Company presents capitalized implementation costs for cloud computing arrangements within prepaid and other current assets, and other non-current assets to properly present the capitalized costs with their related subscription fees.

***Loss Contingencies***

The Company estimates loss contingencies in accordance with ASC Sub-Topic 450-20, *Loss Contingencies* ("ASC 450-20"), which states that a loss contingency shall be accrued by a charge to income if both of the following conditions are met: (i) information available before the consolidated financial statements are issued or are available to be issued indicates that it is probable that a liability had been incurred at the date of the consolidated financial statements and (ii) the amount of loss can be reasonably estimated. We regularly evaluate current information available to us to determine whether such accruals should be adjusted and whether new accruals are required. Refer to Note 12 for additional information.

***Revenue Recognition***

The Company enters into short-term contracts for 'last-mile' satellite and cargo delivery (transportation service), payload hosting and in-orbit servicing options with customers that are primarily in the aerospace industry. For its transportation service arrangements, the Company has a performance obligation of delivering the customers' payload to its designated orbit and recognizes revenue (along with any other fees that have been paid) at a point in time, upon satisfaction of this performance obligation. Additionally, for its in-orbit service arrangements, the Company provides a multitude of services during the mission to its customers. The Company recognizes revenue for these in-orbit services ratably over time on a straight-line basis. The Company also enters into contracts to perform analysis and provide engineering services to U.S. government organizations.

The Company accounts for customer contracts in accordance with ASC Topic 606, *Revenue from Contracts with Customers* ("ASC Topic 606"), which includes the following five-step model:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Identification of the contract, or contracts, with a customer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Identification of the performance obligations in the contract.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Determination of the transaction price.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Allocation of the transaction price to the performance obligations in the contract.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Recognition of revenue when, or as, the Company satisfies a performance obligation.

**MOMENTUS INC.**

**NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS**

**Note 2. Summary of Significant Accounting Policies** (cont.)

The Company estimates variable consideration at the most likely amount, which is included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur. While the Company's standard contracts do not contain refund or recourse provisions that enable its customers to recover any non-refundable fees that have been paid, the Company may issue full or partial refunds, or concessions on future services to customers on a case-by-case basis as necessary to preserve and foster future business relationships and customer goodwill. Contracts to provide engineering services to U.S. government organizations generally have set payments tied to each milestone. When a milestone is achieved, the Company submits the completed service for approval, submits invoices to the government site, and collects on that completed milestone. During the years ended December 31, 2025 and 2024, the Company recorded $0.9 million and $1.8 million, respectively, of revenue from the U.S. government.

As part of its contracts with customers, the Company collects up-front non-refundable deposits prior to launch. As of December 31, 2025 and 2024, the Company had customer deposit balances of $4.2 million and $2.2 million, respectively, related to signed contracts with customers, including firm orders and options (some of which have already been exercised by customers). These deposits are recorded as contract liabilities in the Company's consolidated balance sheets. Included in the collected amount as of December 31, 2025 and 2024, are $0.1 million and $1.9 million, respectively, of non-current deposits.

During the year ended December 31, 2025, the Company recognized $1.1 million of revenue primarily due to engineering services performed under the DARPA NOM4D and DARPA BRIDGES programs, payment under the Space Development Agency HALO program, and forfeited customer deposits primarily related to expired options. Of the $1.1 million of revenue recognized, $0.2 million was derived from the December 31, 2024, contract liability balance. During the year ended December 31, 2024, the Company recognized $2.1 million of revenue due to engineering services performed on the Space Development Agency milestone two agreement and forfeited customer deposits primarily related to expired options. Of the $2.1 million of revenue recognized, $0.3 million was derived from the December 31, 2023, contract liability balance.

The disaggregation of revenue by type is as follows:

---

| | | |
|:---|:---|:---|
| | **Year Ended<br>December 31,** | **Year Ended<br>December 31,** |
| *(in thousands)* | **2025** | **2024** |
| Forfeited customer deposits | $162 | $307 |
| Engineering project services | 948 | 1807 |
| &nbsp;&nbsp;&nbsp;&nbsp;Total revenue | $1110 | $2114 |

---

***Fair Value Measurement***

The Company uses valuation approaches that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. A three-tiered hierarchy is established as a basis for considering such assumptions and for inputs used in the valuation methodologies in measuring fair value. This hierarchy requires that the Company use observable market data, when available, and minimize the use of unobservable inputs when determining fair value:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 1, observable inputs such as quoted prices in active markets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 2, inputs other than the quoted prices in active markets that are observable either directly or indirectly; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 3, unobservable inputs in which there is little or no market data, which requires that the Company develop its own assumptions.

The fair values of cash and cash equivalents, accounts payable, and certain prepaid and other current assets and accrued expenses approximate carrying values due to the short-term maturities of these instruments which fall with Level 1 of the fair value hierarchy. The carrying value of certain other non-current assets and liabilities approximates fair value. The Company had no Level 2 inputs for the years ended December 31, 2025 and 2024.

**Note 2. Summary of Significant Accounting Policies** (cont.)

As of December 31, 2025, the Company does not have any assets measured at fair value on a recurring basis, other than the Credit Provision Derivative (see Note 9 for additional detail). The Credit Provision Derivative is measured at fair value under ASC Topic 815 and is classified within Level 3 of the fair value hierarchy. The Company estimated the fair value of derivative asset based on the expected underutilization payment to be received during 2026.

The change in fair value of the Credit Provision Derivative asset subject to recurring remeasurement was as follows:

---

As of December 31, 2025, the Company has the following liabilities measured at fair value on a recurring basis:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Certain of the Company's warrants are recorded as a derivative liability pursuant to ASC Topic 815, *Derivatives and Hedging* ("ASC Topic 815"), and are classified within Level 3 of the fair value hierarchy as the Company is using the BSM option pricing model.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The May 2025 Convertible Note, issued for non-employee services, is classified as a liability under ASC Topic 718 and measured at fair value. The May 2025 Convertible Note is classified within Level 3 of the fair value hierarchy as the Company is using a convertible bond pricing model to calculate fair value. Key assumptions used to determine the fair value of the May 2025 Convertible Note as of December 31, 2025, were as follows:

---

| | |
|:---|:---|
| Expected term (years) | 0.96 |
| Stock price | $4.87 |
| Volatility | 45.00% |
| Risk-free rate | 3.49% |
| Dividend yield | —% |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Fair Value Option ("FVO") permitted under ASC Topic 825 for the May 2025 Loan. The May 2025 Loan is classified within Level 3 of the fair value hierarchy as the Company is using a convertible bond pricing model to calculate fair value. Prior to extinguishment in 2025, the May 2025 Loan was measured at fair value based on the expected settlement amount of the loan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The AIR Warrants are classified as a liability under ASC Topic 480 and measured at fair value. The AIR Warrants are classified within Level 3 of the fair value hierarchy because their fair value is determined using an option pricing model that incorporates significant unobservable inputs, including expected stock price volatility and the discount rate on the underlying junior convertible notes. The Company calculates the fair value by weighting two different approaches. Key assumptions used to determine the fair value of the AIR Warrants as of December 31, 2025, were as follows:

---

| | | |
|:---|:---|:---|
| | **Underlying Investor Warrants (BSM)** | **Junior Convertible Notes** |
| Expected term (years) | 5.00 | 0.92 |
| Stock price | $4.87 | $4.87 |
| Volatility | 87.50% | 45.00% |
| Risk-free rate | 3.73% | 3.50% |
| Dividend yield | —% | —% |

**Note 2. Summary of Significant Accounting Policies** (cont.)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The ELOC Pre-funded Warrants are classified as a liability under ASC Topic 815 and measured at fair value. The ELOC Pre-funded Warrants are classified within Level 3 of the fair value hierarchy because the number of shares issuable upon exercise is subject to contingent variability, which requires management's estimate of the probability that the trigger will not occur. The Company estimated the fair value of the warrants based on the per share fair value of the Class A common stock at issuance and upon exercise, less the $0.00001 exercise price, multiplied by the current (non-contingent) number of shares.

The primary significant unobservable input used in the valuation of the warrants and convertible notes is expected stock price volatility. Expected stock price volatility is based on the actual historical volatility of a group of comparable publicly traded companies observed over a historical period equal to the expected remaining life of the instruments. The risk-free interest rate is based on the U.S. Treasury yield curve in effect on the date of valuation equal to the remaining expected life of the instruments. The expected term was based on the maturity of the instruments, which is 5 years for Class A common stock warrants and 1.5 years for Class B common stock warrants. The dividend yield percentage is zero because the Company does not currently pay dividends, nor does it intend to do so during the expected term of the instruments. There were no transfers between levels of input during the years ended December 31, 2025 and 2024.

The change in fair values of liabilities subject to recurring remeasurement were as follows:

***Warrant Liability***

Certain of the Company's private warrants and stock purchase warrants are recorded as derivative liabilities pursuant to ASC Topic 815, including the ELOC Pre-funded Warrants, or liabilities pursuant to ASC Topic 480, including the AIR Warrants, and are classified within Level 3 of the fair value hierarchy as the Company uses significant unobservable inputs is using the BSM option pricing model, or other appropriate valuation techniques, to calculate fair value. See Note 9 for additional information. Significant unobservable inputs, prior to the Company's stock being publicly listed, included stock price, volatility and expected term. At the end of each reporting period, changes in fair value during the period are recognized as components of other income within the consolidated statements of operations. The Company will continue to adjust the warrant liability for changes in fair value until the earlier of (i) the exercise or expiration of the warrants or (ii) the redemption of the warrants, at which time the warrants will be reclassified to additional paid-in capital within the consolidated statements of stockholders' equity (deficit).

The warrants issued by Momentus Inc. prior to the Business Combination were exercised in connection with the Business Combination and as a result, the Company performed a fair value measurement of those warrants on the Closing and recorded the change in the instruments' fair values prior to converting them to equity. The warrants assumed by the Company as a result of the Business Combination remain outstanding.

*Public and Private Warrants*

Prior to the Business Combination, SRAC issued 903 private placement warrants ("Private Warrants") and 691 public warrants ("Public Warrants" and, collectively with the Private Warrants, the "Public and Private Warrants"). Each whole warrant entitles the holder to purchase one share of the Company's Class A common stock at a price of

**NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS**

**Note 2. Summary of Significant Accounting Policies** (cont.)

$143,693 per share, subject to adjustments and will expire five years after the Business Combination or earlier upon redemption or liquidation.

The Private Warrants do not meet the derivative scope exception and are accounted for as derivative liabilities. Specifically, the Private Warrants contain provisions that cause the settlement amounts to be dependent upon the characteristics of the holder of the warrant which is not an input into the pricing of a fixed-for-fixed option on equity shares. Therefore, the Private Warrants are not considered indexed to the Company's stock and should be classified as a liability. Since the Private Warrants meet the definition of a derivative, the Company recorded the Private Warrants as liabilities on the consolidated balance sheets at fair value upon the Closing, with subsequent changes in the fair value recognized in the consolidated statements of operations at each reporting date. The fair value of the Private Warrants was measured using the BSM option pricing model at each measurement date.

In addition, the Public Warrants are accounted for as equity classified by the Company. On consummation of the Business Combination, the Company recorded equity related to the Public Warrants of $20.2 million, with an offsetting entry to additional paid-in capital. Similarly, on the consummation of the Business Combination, the Company recorded a liability related to the Private Warrants of $31.2 million, with an offsetting entry to additional paid-in capital.

The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC Topic 815, at the initial recognition.

Other than the Public and Private Warrants noted above, the Company also had other warrants issued and outstanding which were recognized as derivative liabilities in accordance with ASC Topic 815 until they were fully exercised. Accordingly, the Company recognized the warrant instruments as liabilities at fair value and adjusts the instruments to fair value at each reporting period until exercised. The fair value of the warrant liabilities issued were initially measured using the BSM option pricing model, or other appropriate valuation techniques, and were subsequently remeasured at each reporting period with changes recorded as a component of other income in the Company's consolidated statements of operations. Derivative warrant liabilities are classified as non-current as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities. See Note 9 for additional information.

***Equity Classified Warrants***

Subsequent to the Business Combination, the Company has issued warrants in conjunction with various securities purchase agreements and borrowings (see Note 8 and Note 9 for additional information). The warrants are freestanding equity-linked instruments that meet the indexation and equity classification criteria of ASC Sub-Topic 815-40.

The grant-date fair value of these warrants is recorded in additional paid-in capital on the consolidated balance sheets. The fair value of the warrants are measured using the BSM option pricing model on the grant date.

***Modification of Equity Classified Warrants***

A change in the terms or conditions of a warrant is accounted for as a modification. For a warrant modification accounted for under ASC Topic 815, the effect of a modification shall be measured as the difference between the fair value of the modified warrant and the fair value of the original warrant immediately before its terms are modified, with each measured on the modification date. The accounting for incremental fair value of the modified warrants over the original warrants is based on the specific facts and circumstances related to the modification. When a modification is directly attributable to an equity offering, the incremental change in fair value of the warrants is accounted for as an equity issuance cost. When a modification is directly attributable to a debt offering, the incremental change in fair value of the warrants is accounted for as a debt discount or debt issuance cost. For all other modifications, the incremental change in fair value is recognized as a deemed dividend.

***Convertible Instruments***

The Company evaluates its convertible debt issuances to determine if those contracts or embedded components of those contracts qualify as derivatives requiring separate recognition in the Company's financial statements. Entities

**Note 2. Summary of Significant Accounting Policies** (cont.)

must consider whether to classify contracts that may be settled in the Company's own stock, such as warrants, as equity of the entity or as an asset or liability. If an event that is not within the entity's control could require net cash settlement, then the contract should be classified as an asset or a liability rather than as equity. Convertible instruments issued for non-employee services, such as the May 2025 Convertible Note, are classified as liabilities under ASC Topic 718 if cash settlement is possible, measured at fair value each reporting period with changes in fair value recognized in operating expenses (see Note 8).

If the embedded conversion options do not require bifurcation, the Company then evaluates for the existence of a beneficial conversion feature by comparing the fair value of the Company's underlying stock as of the commitment date to the effective conversion price of the instrument (the intrinsic value).

Debt discounts under these arrangements are amortized over the term of the related debt to their stated date of redemption and are classified in interest expense in the consolidated statements of operations. For liability-classified convertible instruments under ASC Topic 718, no debt discount is recorded, as fair value remeasurement captures all value changes.

Amendments to convertible instruments are evaluated as to whether they should be accounted for as a modification of the original instrument with no change to the accounting or, if the terms are substantially changed, as an extinguishment of the original instrument and the issuance of a new instrument.

***Fair Value Option for Convertible Debt***

The Company elected the FVO for recognition of its convertible debt issued to J.J. Astor & Co., as permitted under ASC Topic 825, *Financial Instruments* (see discussion of the May 2025 Loan in Note 8). Under the FVO, the Company recognizes the convertible debt at fair value with changes in fair value recognized in earnings. The FVO may be applied instrument by instrument, but it is irrevocable. As a result of applying the FVO, any direct costs and fees related to the convertible debt is recognized in operating expense in the consolidated statements of operations as incurred and not deferred. Changes in fair value of the convertible debt are recognized as a separate line in the consolidated statements of operations and comprehensive loss.

***Equity Issuance Costs***

The Company incurs costs related to the issuance of equity securities. These costs are initially recorded as a prepaid asset under ASC Topic 340 and reclassified to additional paid-in capital as the related equity is earned through service delivery, or amortized to expense, typically research and development, based on the service period or delivery pattern.

***Basic and Diluted Loss Per Share***

Net loss per share is provided in accordance with ASC Sub-Topic 260-10, *Earnings per Share*. Basic net loss per share is computed by dividing losses by the weighted average number of common shares outstanding during the period. Diluted loss per share gives effect to all dilutive potential common shares outstanding during the period. Diluted loss per share excludes all potential common shares if their effect is anti-dilutive. See Note 11 for additional information.

***Impairment of Long-lived Assets***

The Company evaluates the carrying value of long-lived assets, which includes intangible assets, on an annual basis, or more frequently whenever circumstances indicate a long-lived asset may be impaired. When indicators of impairment exist, the Company estimates future undiscounted cash flows attributable to such assets. In the event cash flows are not expected to be sufficient to recover the recorded value of the assets, the assets are written down to their estimated fair value. During the years ended December 31, 2025 and 2024, there were no impairments of long-lived assets. See Note 4 and Note 5 for additional information.

***Stock-based Compensation***

The Company has a stock incentive plan under which equity awards are granted to employees, directors, and consultants. The Company also issues equity or liability instruments, such as convertible notes, to non-employees for services under ASC Topic 718, which are measured at fair value at issuance and, for liability-classified instruments, remeasured each reporting period with changes in fair value recognized in operating expenses.

**NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS**

**Note 2. Summary of Significant Accounting Policies** (cont.)

stock-based payments are recognized in the consolidated financial statements based on their respective grant date fair values.

RSU fair value is based on our closing stock price on the day of the grant. Stock option fair value is determined using the BSM option pricing model. The model requires management to make a number of assumptions, including expected volatility of the Company's stock, expected life of the option, risk-free interest rate, and expected dividends. For non-employee awards, such as the May 2025 Convertible Note and shares issued in relation to the VLD MSA (defined in Note 9), fair value is determined using valuation models (e.g., Black-Scholes or similar) with unobservable inputs like volatility and discount rates, and liability-classified awards are remeasured until settlement (see Note 8). Employee Stock Purchase Plan ("ESPP") compensation fair value is also determined using the BSM option pricing model, using a six-month expected term to conform with the six month ESPP offering period.

The grant-date fair value of equity awards is expensed over the related service period which is typically the vesting period, and expense is only recognized for awards that are expected to vest. The Company accounts for forfeitures as they occur.

***401(k) Plan***

The Company has a 401(k) plan that it offers to its full-time employees. The Company did not contribute to the plan during the years ended December 31, 2025 and 2024.

***Research and Development Costs***

Research and development costs are expensed as incurred. Research and development costs include activities to develop existing and future technologies for the Company's vehicles. Research and development activities include basic research, applied research, design, development, and related test program activities. Costs incurred for developing our vehicles primarily include equipment and labor hours (both internal and subcontractors).

Nonrefundable advance payments for goods or services that will be used or rendered for future research and development activities related to an executory contractual arrangement are deferred and capitalized. These advance payments are recognized as an expense as the related goods are delivered or services performed. When the related goods are no longer expected to be delivered or services rendered, the capitalized advance payment is charged to expense.

***Leases***

The Company determines if an arrangement contains a lease at inception based on whether there is an identified property, plant or equipment and whether the Company controls the use of the identified asset throughout the period of use.

Operating leases are included in the accompanying consolidated balance sheets. Operating lease right-of-use ("ROU") assets represent the Company's right to use an underlying asset for the lease term. Lease liabilities represent the Company's obligation to make lease payments arising from the lease and are included in current and non-current liabilities. Operating lease ROU assets and lease liabilities are recognized at the lease inception date based on the present value of lease payments over the lease term discounted based on the more readily determinable of (i) the rate implicit in the lease or (ii) the Company's incremental borrowing rate (which is the estimated rate the Company would be required to pay for a collateralized borrowing equal to the total lease payments over the term of the lease). Because the Company's operating leases generally do not provide an implicit rate, the Company estimates its incremental borrowing rate based on the information available at lease commencement date for borrowings with a similar term.

The Company's operating lease ROU assets are measured based on the corresponding operating lease liability adjusted for (i) payments made to the lessor at or before the commencement date, (ii) initial direct costs incurred, and (iii) tenant incentives under the lease. The Company does not assume renewals or early terminations unless it is reasonably certain to exercise these options at commencement. The Company elected the practical expedient which allows the Company to not allocate consideration between lease and non-lease components. Variable lease payments are recognized in the period in which the obligation for those payments is incurred. In addition, the Company elected the practical expedient such that it does not recognize ROU assets or lease liabilities for leases with a term of

**Note 2. Summary of Significant Accounting Policies** (cont.)

12 months or less of all asset classes. Operating lease expense is recognized on a straight-line basis over the lease term. See Note 6 for additional details on the Company's leases.

***Income Taxes***

The Company accounts for income taxes in accordance with authoritative guidance, which requires the use of the asset and liability method. Under this method, deferred income tax assets and liabilities are determined based upon the difference between the financial statement carrying amounts and the tax basis of assets and liabilities and are measured using the enacted tax rate expected to apply to taxable income in the years in which the differences are expected to be reversed.

Significant judgment is required in determining any valuation allowance recorded against deferred tax assets. In assessing the need for a valuation allowance, management considers all available evidence, including past operating results, estimates of future taxable income, and the feasibility of tax planning strategies.

In the event that management changes its determination as to the amount of deferred tax assets that can be realized, the Company will adjust its valuation allowance with a corresponding impact to the provision for income taxes in the period in which such determination is made.

The Company is required to evaluate the tax positions taken in the course of preparing its tax returns to determine whether tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax benefits of positions not deemed to meet the "more likely than not" threshold would be recorded as a tax expense in the current year. The amount recognized is subject to estimate and management judgment with respect to the likely outcome of each uncertain tax position. The amount that is ultimately sustained for an individual uncertain tax position or for all uncertain tax positions in the aggregate could differ from the amount that is initially recognized.

***Concentrations of Risk***

Financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents. The Company places its cash and cash equivalents in banks that management believes are creditworthy, however deposits may exceed federally insured limits.

***Segment Reporting***

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing operating performance. In consideration of ASC Topic 280, *Segment Reporting* ("ASC Topic 280"), we are not organized around specific services or geographic regions.

Our chief operating decision maker ("CODM") uses financial information to evaluate our performance, which is the same basis on which our results and performance are communicated to our Board of Directors. All of the Company's long-lived assets are held domestically in the United States and of the $1.1 million of revenue recognized by the Company during the year ended December 31, 2025, 10% was derived from customers domiciled in foreign countries. Based on the information described above and in accordance with the applicable literature, management has concluded that we are organized and operated as one operating and reportable segment.

***Recently Issued Accounting Standards***

Although there are several new accounting pronouncements issued or proposed by the FASB, which have been adopted or will be adopted as applicable, management does not believe any of these accounting pronouncements has had or will have a material impact on the Company's consolidated financial position or results of operations.

In October 2023, the FASB issued ASU 2023-06, *Disclosure Improvements: Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative* ("ASU 2023-06"). The amendments in this ASU are expected to clarify or improve disclosure and presentation requirements of a variety of ASC topics by aligning them with the SEC's regulations. ASU 2023-06 will become effective for each amendment on the effective date of the SEC's corresponding disclosure rule changes, which must occur by June 30, 2027, or the amendments will not take effect. The Company does not anticipate that the adoption of ASU 2023-06 will have a material impact on its consolidated financial statements and related disclosures.

**Note 2. Summary of Significant Accounting Policies** (cont.)

In November 2024, the FASB issued ASU 2024-03, *Disaggregation of Income Statement Expenses (DISE)* ("ASU 2024-03"), that requires disclosures about specific types of expenses included in the expense captions presented on the face of the income statement as well as disclosures about selling expenses. Public entities must adopt the new guidance for fiscal years beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. The amendments in ASU 2024-06 will be applied prospectively with the option for retrospective application and early adoption is permitted. The Company is in the process of evaluating the potential impact that ASU 2024-03 will have on its consolidated financial statements and related disclosures.

In December 2025, the FASB issued ASU 2025-11, *Interim Reporting (Topic 270)—Narrow-Scope Improvements* ("ASU 2025-11"), which provides a clearer framework and more consistent application of interim disclosure requirements for public business entities. The guidance is effective for interim periods within annual periods beginning after December 15, 2027. The amendments in ASU 2025-11 will be applied prospectively with the option for retrospective application and early adoption is permitted. The Company does not anticipate that the adoption of ASU 2025-11 will have a material impact on its consolidated financial statements and related disclosures.

In December 2025, the FASB issued ASU No. 2025-12, *Codification Improvements* ("ASU 2025-12"), which refines existing guidance to further enhance the interpretation and application of the Codification. The guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2026. The amendments in ASU 2025-12 will be applied prospectively with the option for retrospective application and early adoption is permitted. The Company does not anticipate that the adoption of ASU 2025-12 will have a material impact on its consolidated financial statements and related disclosures.

***Recently Adopted Accounting Standards***

In November 2023, the FASB issued ASU 2023-07, *Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures*, requiring public entities to disclose information about their reportable segments' significant expenses and other segment items on an interim and annual basis. Public entities with a single reportable segment are required to apply the disclosure requirements in ASU 2023-07, as well as all existing segment disclosures and reconciliation requirements in ASC Topic 280 on an interim and annual basis. The Company adopted ASU 2023-07 during the year ended December 31, 2024. See Note 15, *Segment and Geographic Information*, in the accompanying notes to the consolidated financial statements for further detail.

In December 2023, the FASB issued ASU 2023-09, *Income Taxes (Topic 740): Improvements to Income Tax Disclosures* ("ASU 2023-09"), that addresses requests for improved income tax disclosures from investors that use the financial statements to make capital allocation decisions. Public entities must adopt the new guidance for fiscal years beginning after December 15, 2024. The amendments in ASU 2023-09 should be applied on a prospective basis. Retrospective application and early adoption is permitted. The Company adopted ASU 2023-09 on January 1, 2025, on a retrospective basis, which did not have a material impact on its consolidated financial statements and related disclosures.

In March 2024, the FASB issued ASU 2024-02 which removes references to the Board's concepts statements from the FASB ASC. The ASU is part of the Board's standing project to make "Codification updates for technical corrections such as conforming amendments, clarifications to guidance, simplifications to wording or the structure of guidance, and other minor improvements." The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2024. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2025. The Company adopted ASU 2024-02 on January 1, 2025, which did not have a material impact on its consolidated financial statements and related disclosures.

**Note 6. Leases** 

The Company leases office space under non-cancellable operating leases. In January 2021, the Company commenced a lease in San Jose, California. Due to an event of default under the lease occurring in October 2024, and the likelihood of the landlord executing its right to early terminate the lease as a result, the Company determined this represented a remeasurement event and remeasured the lease as of December 31, 2024. On February 26, 2025, the landlord executed its option to terminate the lease early on March 31, 2026. In December 2025, the Company commenced another lease in San Jose, California. This lease has an expiration date in September 2032.

**Note 8. Loan Payable**

***September 2025 Convertible Note***

On September 25, 2025, the Company entered into a Securities Purchase Agreement (the "September 2025 SPA") with an investor (the "September 2025 Private Placement") pursuant to which the Company agreed to sell (i) a Junior Secured Convertible Note having an aggregate principal amount of $1.6 million (the "September 2025 Convertible Note"), (ii) warrants to purchase up to 81,847 shares of Class A common stock (the "September 2025 Warrants"), and (iii) warrants to purchase up to $4.0 million of additional September 2025 Convertible Notes and September 2025 Warrants (the "AIR Warrants").

The September 2025 SPA provides that the Company will indemnify the investor for any claims and losses. This indemnification by the Company was an embedded derivative that required bifurcation and recognition as a derivative liability ("Indemnification Derivative"). The Indemnification Derivative instrument is recorded at fair value and marked-to-market each reporting period with changes in fair value being reflected in earnings. As of the issuance date and December 31, 2025, the Indemnification Derivative was valued at zero.

The September 2025 Convertible Note bears an annual interest rate of 8%. Unless earlier converted, principal and any accrued unpaid interest on the September 2025 Convertible Note are due at maturity in September 2026. The September 2025 Convertible Note, including interest accrued thereon, is convertible at any time, in whole or in part, at the option of the holder into shares of Class A common stock at a conversion price of $19.92 per share, subject to certain beneficial ownership limitations provided for in the terms of the September 2025 Convertible Note. The September 2025 Convertible Note is a junior secured obligation of the Company and is secured by certain personal property of the Company.

The September 2025 Warrants have an exercise price of $24.99 per share. The September 2025 Warrants may be exercised at any time after issuance and will expire five years from the date of issuance. The exercise of the September 2025 Warrants are subject to certain beneficial ownership limitations provided for in the terms of the September 2025 Warrants. The September 2025 Warrants meet the requirements for equity classification.

The Company received aggregate gross proceeds from the September 2025 Private Placement of approximately $1.5 million, before deducting estimated lender fees and debt issuance costs of $0.1 million paid by the Company.

The initial fair value of the AIR Warrants (discussed below) and the ELOC Pre-funded Warrants (see discussion in Note 9) exceed the net proceeds received from the September 2025 Private Placement. Therefore, upon allocating the net proceeds of the September 2025 Private Placement, no amounts were allocated to the September 2025 Warrants and the September 2025 Convertible Note was recorded at a 100% discount. The excess fair value of $1.4 million of the AIR Warrants and ELOC Pre-funded Warrants over the net proceeds received was recognized as a loss in other expense in the consolidated statements of operations.

The September 2025 Convertible Note can be prepaid in full at any time, subject to a prepayment fee of 10%. The September 2025 Convertible Note will accelerate and become immediately due upon the occurrence of certain customary events of default including, but not limited to, failure to make payments when due, failure to observe or perform covenants or agreements contained in the September 2025 Convertible Note, the bankruptcy or insolvency of the Company or any of its subsidiaries and unsatisfied judgments against the Company. The mandatory redemption of the September 2025 Convertible Note upon one of these events of default was an embedded

derivative that required bifurcation and recognition as a derivative liability ("September 2025 Default Redemption Derivative"). Furthermore, contingent interest related to these events of default was an embedded derivative also that required bifurcation and recognition as a derivative liability ("September 2025 Default Interest Derivative"). Both the September 2025 Default Redemption Derivative and the September 2025 Default Interest Derivative instruments are recorded at fair value and marked-to-market each reporting period with changes in fair value being reflected in earnings. As of the issuance date and December 31, 2025, both the September 2025 Default Redemption Derivative and the September 2025 Default Interest Derivative were valued at zero.

The September 2025 Convertible Note also contains certain negative covenants, including prohibitions on the incurrence of indebtedness, liens, amendments to the Company's organizational documents, dividends, redemption, related party transactions, and entry into any equity line of credit agreement or variable rate transactions other than an "at the market" offering of the Company's Class A common stock.

As of December 31, 2025, the September 2025 Convertible Note has a carrying amount of $0.4 million, consisting of principal of $1.6 million and net unamortized discount of $1.2 million. The September 2025 Convertible Note has future scheduled maturities of $1.6 million in 2026. For the year ended December 31, 2025, interest recognized on the September 2025 Convertible Note totaled $0.5 million. This amount consists of cash interest expense of $0.04 million and non-cash amortization of debt discount of $0.4 million.

***AIR Warrants***

In connection with the September 2025 Private Placement, the Company issued the AIR Warrants. The AIR Warrants were exercisable by the holder immediately with a five-year term and may be exercised in tranches based on the trading volume and price of the Company's Class A common stock. In addition, the Company may, at its discretion, deliver a call notice requiring the holder to exercise the AIR Warrants, in whole or in part (up to an amount not exceeding two times the average daily trading volume of the Company's Class A common stock over the relevant period), provided that certain trading conditions are satisfied (including the five-day average trading price equaling or exceeding 125% of the original conversion price of the underlying notes). If the trading conditions are not met at the time of the call notice, the holder is not obligated to exercise; however, the Company may cancel any unexercised portion of the AIR Warrants (effectively terminating the remaining commitment) if the holder does not proceed with the investment upon such call. This call feature provides the Company with the ability to compel realization or cancellation under various market conditions.

The AIR Warrants are classified as a liability under ASC Topic 480 as they embody a conditional obligation for the Company to transfer assets through the settlement of the underlying convertible notes.

The AIR Warrants were initially measured at a fair value of $1.9 million on the issuance date, with a corresponding allocation from the proceeds of the September 2025 Private Placement, with the excess fair value of the AIR Warrants over the September 2025 Private Placement proceeds recognized in earnings. The AIR Warrants liability is recorded at fair value and marked-to-market each reporting period with changes in fair value being reflected in earnings. The Company determined the fair value of the AIR Warrants at issuance using two different approaches. Under the first approach, the instruments underlying the AIR Warrants are assumed to have value equal to proceeds received that would have been received upon exercise of the AIR Warrants and, under the second approach, the instruments underlying the AIR Warrants were valued using a convertible bond pricing model for the underlying convertible note and a BSM option pricing model for the underlying common warrants. The fair value was then determined based on the intrinsic value: the difference between the fair value of the instruments underlying the AIR

Warrants and the proceeds that would be received upon exercise of the AIR Warrants. The following inputs were used in the convertible bond and BSM option pricing models:

No AIR Warrants were exercised during the year ended December 31, 2025.

***May 2025 Loan***

On May 30, 2025, the Company and J.J. Astor & Co. entered into a loan agreement (the "May 2025 Loan") pursuant to which the Company may borrow up to $1.5 million in two tranches of $0.75 million each (the first tranche referred to as the "Initial Tranche" and the second as the "Second Tranche") and paid debt issuance costs of $0.2 million. The May 2025 Loan has a maturity date of March 6, 2026, and is payable in 40 weekly installments of $25 thousand, with at least 10% in cash and the remainder in shares at a conversion price of $30.35 per share. The May 2025 Loan can be prepaid in full at any time, subject to a prepayment fee of 120% of the outstanding principal plus costs.

Amounts borrowed under the May 2025 Loan are secured by a lien on substantially all of the assets of the Company. Upon event of default, amounts owing under the May 2025 Loan increase by 120% and are convertible into shares of Class A common stock at a conversion price equal to 80% of the average of the four lowest volume weighted average closing prices of the Class A common stock during the 20 trading days immediately prior to conversion. The Company elected the FVO for recognition of the May 2025 Loan as permitted under ASC Topic 825.

In addition, in connection with the May 2025 Loan, the Company agreed to issue J.J. Astor & Co. warrants to purchase up to 53,386 shares of Class A common stock with an exercise price of $30.35 per share, subject to adjustment (the "Initial Tranche Warrants"), comprising 26,693 warrants for each tranche. The Initial Tranche Warrants had a fair value of $0.6 million. The warrants are fully vested and expire five years from the date of issuance. The Company determined the fair value of the Initial Tranche Warrants by using a BSM option pricing model, with the following assumptions:

---

| | |
|:---|:---|
| Expected term (years) | 5.00 |
| Stock price | $29.99 |
| Volatility | 90.00% |
| Risk-free rate | 4.04% |
| Dividend yield | 0.00% |

---

On June 17, 2025, the Company and J.J. Astor & Co. entered into an amendment to the May 2025 Loan (the "June 2025 Loan Amendment"). The June 2025 Loan Amendment, among other things, revised the conditions for funding the Second Tranche to occur within three business days after the effectiveness of a resale registration statement, subject to Nasdaq listing maintenance, a stock price of not less than $22.31, a market capitalization of not less than $6.7 million, and trading volume conditions. It also reduced the conversion price on both tranches to the lesser of the closing price of the Company's Class A common stock June 2025 Loan Amendment date and the closing price prior to the Second Tranche issuance. Additionally, the June 2025 Loan Amendment introduced a cash make-whole payment upon conversion equal to the difference between the conversion price and the lower of the closing price on conversion or the lowest volume weighted average closing price over 20 prior trading days. If not paid in cash, the Company will issue shares equal to the make-whole amount divided by the make-whole price. If the Company completes an equity offering sufficient to repay the Initial Tranche before the Second Tranche funding

date, the obligation to issue the Second Tranche is suspended, with a $0.1 million termination fee and issuance of warrants for 26,693 shares of Class A common stock (the "Second Tranche Warrants").

The May 2025 Loan contains customary events of default, upon which the outstanding obligations may be accelerated. The loan ranks senior to unsecured indebtedness. The Company was in compliance with all covenants prior to extinguishment of the May 2025 Loan on July 1, 2025.

On July 1, 2025, the Company prepaid $1.0 million, inclusive of the $0.1 million termination fee, in order to extinguish the May 2025 Loan. In addition, in relation to the extinguishment of the May 2025 Loan on July 1, 2025, the 26,693 Second Tranche Warrants were issued with an exercise price of $20.17 per share. The Second Tranche Warrants had a fair value of $0.4 million, which was included in the measurement of loss on extinguishment of the May 2025 Loan. The Second Tranche Warrants were exercisable immediately after issuance and will expire five years from the date of issuance. The Company determined the fair value of the Second Tranche Warrants by using a BSM option pricing model, with the following assumptions:

---

| | |
|:---|:---|
| Expected term (years) | 5.00 |
| Stock price | $20.17 |
| Volatility | 90.00% |
| Risk-free rate | 3.84% |
| Dividend yield | 0.00% |

---

The Company recognized a $0.5 million loss on extinguishment in the consolidated statements of operations related to the May 2025 Loan.

On May 13, 2025, the Company entered into an unsecured convertible promissory note (the "May 2025 Convertible Note") with A.G.P./Alliance Global Partners ("AGP") for a principal amount of $1.2 million, issued in exchange for AGP's services in facilitating the issuance of equity securities under the MSA with VLD (see Note 9). The May 2025 Convertible Note bears interest at 4.5% per annum and matures on November 13, 2026, unless earlier converted or prepaid. AGP may elect to convert all or any portion of the outstanding principal and accrued interest into shares of the Company's Class A common stock at a conversion price of $29.81 per share, based on the closing price on May 9, 2025, subject to adjustment for stock splits, dividends, or similar events. At maturity, all outstanding principal and accrued interest are payable in cash or, at AGP's option, in shares of Class A common stock at the conversion price. The Company may prepay the May 2025 Convertible Note in whole or in part at any time without penalty.

The May 2025 Convertible Note is classified as a liability under ASC Topic 718, as it was issued to a non-employee for services, and is remeasured at fair value at each reporting period until settlement, with changes in fair value recognized in earnings as part of operating expenses. The note represents payment for legal services incurred in relation to the VLD MSA. Upon issuance, the Company recognized $0.3 million of legal expense related to the May 2025 Convertible Note in selling, general and administrative expenses in the Company's consolidated statements of operations.

The May 2025 Convertible Note contains customary events of default, upon which the outstanding obligations may be accelerated. The note is unsecured and ranks pari passu with the Company's other unsecured indebtedness. The Company was in compliance with all covenants as of December 31, 2025.

On June 17, 2025, the Company and AGP executed a letter agreement (the "June 2025 Note Amendment") modifying the terms of the May 2025 Convertible Note. The June 2025 Note Amendment provided that a new convertible promissory note with a reduced principal amount of $0.5 million (the "Amended Note") will replace the May 2025 Convertible Note. AGP agreed to waive any claim or recourse with respect to the $0.7 million differential between the May 2025 Convertible Note and the Amended Note. The Amended Note would retain substantially similar terms to the May 2025 Convertible Note, including the interest rate, maturity, conversion price, and conversion mechanics, with the only change being the reduction of the principal from $1.2 million to $0.5 million. The June 2025 Note Amendment was accounted for as a modification, with no change to the accounting treatment, as the note remains liability-classified and continues to be remeasured at fair value at each reporting period. No additional costs or premiums were recognized.

***December 2024 Loan***

On December 13, 2024, the Company and J.J. Astor & Co. entered into a loan agreement (the "December 2024 Loan") pursuant to which the Company borrowed $2.0 million and paid debt issuance costs of $0.3 million. The December 2024 Loan had a maturity date of September 19, 2025, and was payable in 40 weekly installments of $68 thousand. The December 2024 Loan could be prepaid at any time on or before January 13, 2025, for $2.4 million and at any time thereafter through the maturity date for $2.7 million.

Amounts borrowed under the December 2024 Loan are secured by a lien on substantially all of the assets of the Company. Upon event of default, amounts owing under the December 2024 Loan are convertible into shares of Class A common stock at a conversion price of $105.67 per share prior to May 5, 2025, and thereafter the conversion price will be reduced to 80% of the average of the four lowest volume weighted average closing prices of the Class A common stock during the 20 trading days immediately prior to conversion.

In addition, in connection with the December 2024 Loan, the Company agreed to issue J.J. Astor & Co. warrants to purchase up to 1,601 shares of Class A common stock with an exercise price of $105.67 per share (the "December 2024 Wolverine Warrants"). The December 2024 Wolverine Warrants had a relative value of $0.1 million which was accounted for as an additional debt issuance cost for the December 2024 Loan. The warrants are fully vested, and expire five years from the date of issuance. The Company determined the fair value of the December 2024 Wolverine Warrants by using a BSM option pricing model, with the following assumptions:

---

| | |
|:---|:---|
| Expected term (years) | 5.01 |
| Stock price | $105.67 |
| Volatility | 100.00% |
| Risk-free rate | 4.25% |
| Dividend yield | 0.00% |

---

On December 18, 2024, the Company prepaid $2.4 million in order to extinguish the December 2024 Loan. The Company recognized a $0.8 million loss on extinguishment in the consolidated statements of operations related to the December 2024 Loan.

In connection with the December 2024 Loan, the Company agreed to issue J.J. Astor & Co. a second warrant that is exercisable and issuable upon certain customary events of default to purchase up to 16,007 shares of Class A common stock with an exercise price per share equal to the closing price of the Class A common stock as traded in the applicable trading market on the date of the event of default, subject to adjustment (the "Default Warrants"). The Default Warrants were an embedded derivative that required bifurcation and recognition as a derivative liability (the "Default Warrant Derivative"). The Default Warrant Derivative instrument is recorded at fair value and marked-to-market each reporting period with changes in fair value being reflected in earnings. As of the issuance date, and immediately prior to extinguishment of the December 2024 Loan on December 18, 2024, the Default Warrant Derivative was valued at zero.

***SIV Convertible Promissory Notes***

On July 12, 2024, the Company and Space Infrastructure Ventures ("SIV") entered into a secured convertible promissory note (the "July 2024 Convertible Note") pursuant to which the Company borrowed $2.3 million as of September 26, 2024. The July 2024 Convertible Note bears an annual interest rate of 15%. Principal on the July 2024 Convertible Note was originally to be re-paid in four equal payments on a quarterly basis, commencing on December 1, 2024, and maturing on September 1, 2025, at which time all accrued interest is due.

Amounts borrowed under the July 2024 Convertible Note are secured by a lien on substantially all of the assets of the Company. In lieu of cash payments of accrued interest, SIV, in its sole discretion, may elect to receive shares of Class A common stock at an original conversion price of $132.27 per share. On the maturity date, subject to the satisfaction of applicable legal and regulatory conditions, all outstanding obligations under the July 2024 Convertible Note automatically convert into Class A common stock at the conversion price.

The July 2024 Convertible Note requires SIV's consent to take certain actions, such as increasing compensation, purchasing assets, extending financing, making capital expenditures, repaying debts outside the ordinary course of business or investing in any entity or enterprise.

**Note 8. Loan Payable** (cont.)

The July 2024 Convertible Note can be prepaid in full at any time, subject to a prepayment penalty fee of 10%. The July 2024 Convertible Note will accelerate and become immediately due upon the occurrence of certain customary events of default, including failure to pay amounts owing when due and/or certain events involving a discontinuation of our business or certain types of proceedings involving insolvency, bankruptcy, receivership and the like, or a change of control of Momentus. Contingent interest related to these events of default was an embedded derivative that required bifurcation and recognition as a derivative liability ("July 2024 Default Interest Derivative"). The July 2024 Default Interest Derivative instrument is recorded at fair value and marked-to-market each reporting period with changes in fair value being reflected in earnings. As of the issuance date, December 31, 2024, and upon extinguishment at final maturity of the July 2024 Convertible Note on December 1, 2025, the July 2024 Default Interest Derivative was valued at zero.

On October 24, 2024, the Company and SIV entered into a secured convertible promissory note (the "October 2024 Convertible Note" and, collectively with the July 2024 Convertible Note, the "SIV Convertible Notes") pursuant to which the Company borrowed $3.0 million in two tranches, consisting of (i) an initial loan in the principal amount of $2.0 million, and (ii) up to an additional $1.0 million in principal amount which could be borrowed from December 2, 2024 through February 14, 2025. Borrowings under the October 2024 Convertible Note bear interest at 15% per annum. The October 2024 Convertible Note has a maturity date of October 24, 2025, at which time all principal and accrued interest is due. The Company paid debt issuance costs of $0.1 million in relation to borrowing $2.0 million under the first tranche of the October 2024 Convertible Note.

As a third-party debt issuance cost related to the October 2024 Convertible Note, the Company agreed to issue investor warrants to purchase up to 20,009 shares of Class A common stock with an exercise price of $143.69 per share (the "Investor Warrants"). The Investor Warrants had a fair value of $2.0 million which was as accounted for as debt issuance costs allocated between two tranches of the October 2024 Convertible Note; $1.3 million was allocated to the first tranche and $0.7 million was allocated to the second tranche. The investor may not exercise the Investor Warrants prior to April 24, 2025, and the Investor Warrants will expire April 24, 2030. The Company determined the fair value of the warrants by using a BSM option pricing model, with the following assumptions:

---

| Expected term (years) | 5.50 |
| Stock price | $132.27 |

Amounts borrowed under the October 2024 Convertible Note are secured by a lien on substantially all of the assets of the Company. At any time after the date that is six months after the original issuance date of the October 2024 Convertible Note, SIV, in its sole discretion, may convert some or all of the outstanding obligations under the October 2024 Convertible Note into shares of Class A common stock at an original conversion price of $132.27 per share.

In addition, in connection with the first tranche of the October 2024 Convertible Note, the Company agreed to issue SIV warrants to purchase up to 15,124 shares of Class A common stock with an exercise price of $132.27 per share (the "October 2024 SIV Warrants"). The October 2024 SIV Warrants had a relative value of $0.8 million which was as accounted for as an additional debt issuance cost for the October 2024 Convertible Note. SIV may not exercise the October 2024 SIV Warrants prior to April 24, 2025, and the October 2024 SIV Warrants will expire April 24, 2030. The Company determined the fair value of the warrants by using a BSM option pricing model, with the following assumptions:

Neither the October 2024 Convertible Note nor the October 2024 SIV Warrants can be converted or exercised if it would cause the aggregate number of shares of Class A common stock beneficially owned by SIV to exceed 9.99% of the number of shares of Class A common stock outstanding immediately after giving effect to the conversion or

exercise, as applicable. Conversion of the October 2024 Convertible Note and exercise of the October 2024 SIV Warrants are also subject to compliance with applicable Nasdaq rules, and if shareholder approval is required the Company will use commercially reasonable efforts to obtain such approval.

The October 2024 Convertible Note requires SIV's consent to take certain actions, such as purchasing assets outside the ordinary course of business, extending financing, making capital expenditures in excess of $0.1 million, repaying debts outside the ordinary course of business or investing in any entity or enterprise.

The October 2024 Convertible Note can be prepaid in full at any time, subject to a prepayment fee of 10%. The October 2024 Convertible Note will accelerate and become immediately due upon the occurrence of certain customary events of default, including failure to pay amounts owing when due and/or certain events involving a discontinuation of our business or certain types of proceedings involving insolvency, bankruptcy, receivership and the like, or a change of control of the Company. Contingent interest related to these events of default was an embedded derivative that required bifurcation and recognition as a derivative liability ("October 2024 Default Interest Derivative"). The October 2024 Default Interest Derivative instrument is recorded at fair value and marked-to-market each reporting period with changes in fair value being reflected in earnings. As of the issuance date, December 31, 2024, and December 31, 2025, the October 2024 Default Interest Derivative was valued at zero.

In November 2024, the Company amended the SIV Convertible Notes (the "November 2024 Amendment"). The November 2024 Amendment, among other things, accelerated the borrowing date for the second tranche of the October 2024 Convertible Note, for which the Company immediately borrowed the $1.0 million available under the second tranche, and provided that amounts owed under both the July 2024 Convertible Note and the October 2024 Convertible Note may be converted to Class A common stock at any time. The November 2024 Amendment was accounted for as an extinguishment of both of the SIV Convertible Notes. The Company recognized a $3.2 million loss on extinguishment in the consolidated statements of operations related to the November 2024 Amendment, resulting from the difference between the carrying value and reacquisition price of the July 2024 Convertible Note and the first tranche of the October 2024 Convertible Note. The Company recognized an aggregate debt premium of $1.2 million related to the July 2024 Convertible Note and the first tranche of the October 2024 Convertible Note as a result. Furthermore, the Company recognized an additional $0.3 million loss on extinguishment in the consolidated statements of operations for a debt premium resulting from the difference between the proceeds received and fair value of the second tranche of the October 2024 Convertible Note.

In addition, in connection with the November 2024 Amendment, the Company issued to SIV warrants to purchase up to 10,828 shares of Class A common stock with an exercise price of $132.27 per share (the "December 2024 SIV Warrants"). The December 2024 SIV Warrants had a relative value of $0.5 million which was as accounted for as an additional debt issuance cost for the second tranche of the October 2024 Convertible Note. SIV was prohibited to exercise the December 2024 SIV Warrants prior to April 24, 2025, and the December 2024 SIV Warrants will expire April 24, 2030. The Company determined the fair value of the warrants by using a BSM option pricing model, with the following assumptions:

---

| | |
|:---|:---|
| Expected term (years) | 5.38 |
| Stock price | $139.94 |
| Volatility | 97.50% |
| Risk-free rate | 4.08% |
| Dividend yield | 0.00% |

The Company capitalized cash debt issuance costs of $0.1 million in relation to the November 2024 Amendment. The debt issuance costs, including $0.7 million allocated from the Investor Warrants and $0.5 million related to the December 2024 SIV Warrants, and $0.3 million debt premium for the second tranche of the October 2024 Convertible Note were amortized over the term of the October 2024 Convertible Note, until the September 2025 Amendment discussed below, using an effective interest rate of 348%. The debt premium of $0.7 million related to the first tranche of the October 2024 Convertible Note was amortized over the term of the October 2024 Convertible Note, prior to the September 2025 Amendment, using an effective interest rate of (18)%.

On March 3, 2025, the Board of Directors of the Company approved a reduction in the conversion price for the July 2024 Convertible Note from $132.27 per share to $37.84 per share during the period beginning on March 3, 2025, and continuing until there are no further obligations outstanding under the July 2024 Convertible Note.

**Note 8. Loan Payable** (cont.)

reduction in the conversion price for the July 2024 Convertible Note was accounted for as an extinguishment. The Company recognized a $0.1 million gain on extinguishment in the consolidated statements of operations related to this extinguishment, resulting from the difference between the carrying value and reacquisition price of the July 2024 Convertible Note. The Company recognized a debt premium of $0.2 million related to the July 2024 Convertible Note, which was amortized over the term of the July 2024 Convertible Note, prior to the September 2025 Amendment, using an effective interest rate of (25)%.

On May 16, 2025, the Company offered SIV the opportunity to convert amounts outstanding under the July 2024 Convertible Note, at a reduced conversion price of $31.59 per share, into up to 6,307 shares of Class A common stock and, thereafter, to convert amount outstanding under the October 2024 Convertible Note, at a reduced conversion price of $31.59 per share. Pursuant to this offer, and as part of the Company's May 2025 contractual repayment, on May 20, 2025, SIV converted $0.2 million of principal of the July 2024 Convertible Note into 6,307 shares of Class A common stock at a conversion price of $31.59 per share. The conversion was accounted for as a partial extinguishment of the July 2024 Convertible Note, resulting in a $0.01 million gain on extinguishment in the consolidated statements of operations. In addition to the $0.2 million of principal converted into equity, the Company repaid $0.3 million of principal in cash, and postponed $0.1 million of payments, including $0.06 million of principal and $0.04 million of interest, to the following quarter. The postponement was accounted for as a modification of the July 2024 Convertible Note. SIV did not convert any amounts outstanding under the October 2024 Convertible Note pursuant to this offer.

On September 8, 2025, the Company amended the SIV Convertible Notes (the "September 2025 Amendment"). The September 2025 Amendment, among other things, extended the maturity date of the July 2024 Convertible Note and the October 2024 Convertible Note to December 1, 2025, and March 1, 2026, respectively. As a result of the September 2025 Amendment, the $2.7 million outstanding principal amount of the October 2024 Convertible Note is payable in two tranches, with the first tranche of $1.0 million due on December 1, 2025, and the remaining $1.7 million, plus unpaid accrued interest, due at maturity on March 1, 2026. The September 2025 Amendment further changed the conversion price of both of the SIV Convertible Notes to an amount equal to the lower of (i) $19.81 per share and (ii) a 10% discount to the closing price of the Class A common stock on the day prior to each conversion, but in no event lower than $3.57 per share. The September 2025 Amendment was accounted for as an extinguishment of both of the SIV Convertible Notes. The Company recognized a $2.4 million loss on extinguishment in the consolidated statements of operations related to the September 2025 Amendment, resulting from the difference between the carrying value and reacquisition price of the SIV Convertible Notes.

In addition, in connection with the September 2025 Amendment, the Company issued to SIV warrants to purchase up to 112,045 shares of Class A common stock with an exercise price of $19.81 per share (the "September 2025 SIV Warrants"). The September 2025 SIV Warrants had a fair value of $1.7 million which was included in measurement of the September 2025 Amendment loss on extinguishment. The September 2025 SIV Warrants were exercisable immediately after issuance and will expire five years from the date of issuance. The Company determined the fair value of the September 2025 SIV Warrants by using a BSM option pricing model, with the following assumptions:

---

| | |
|:---|:---|
| Expected term (years) | 5.00 |
| Stock price | $21.42 |
| Volatility | 87.50% |
| Risk-free rate | 3.57% |
| Dividend yield | 0.00% |

---

Furthermore, in connection with the September 2025 Amendment, the Company also agreed to amend each of the October 2024 SIV Warrants and December 2024 SIV Warrants to purchase up to an aggregate of 25,951 shares of Class A common stock at an exercise price of $132.27 per share and a termination date of April 24, 2030 (the "SIV Modified Warrants"). The SIV Modified Warrants were amended on September 8, 2025, to have a reduced exercise price of $19.81 per share. The Company estimated the fair value of the SIV Modified Warrants immediately before and after modification using the BSM option pricing model and determined an incremental increase in fair value of approximately $0.2 million. The incremental change in fair value of the SIV Modified Warrants was included in

The Company capitalized cash debt issuance costs of $0.03 and recognized a debt premium of $0.3 million on the October 2024 Convertible Note in relation to the September 2025 Amendment. The net debt premium of $0.3 million was being amortized over the term of the October 2024 Convertible Note, until the December 2025 Amendment discussed below, using effective interest rates of (7)% and (34)% for the first and second tranches of the October 2024 Convertible Note, respectively. The Company also recognized a $0.1 million debt discount on the July 2024 Convertible Note in relation to the September 2025 Amendment. The debt discount was being amortized over the term of the July 2024 Convertible Note, until extinguishment in December 2025, using an effective interest rate of 103%.

The September 2025 Amendment permits the Company to incur up to $4.0 million of indebtedness on or after December 1, 2025, that is pari passu with the unpaid balance of the SIV Convertible Notes, provided that the Company issues to SIV warrants to purchase up to 10% of the total number of shares of Class A common stock SIV has converted under both of the SIV Convertible Notes after September 8, 2025, with the exercise price per share to correspond with the conversion price applicable under the SIV Convertible Notes at the time of the debt incurrence. Thereafter, the Company will continue to issue to SIV warrants to purchase shares of Class A common equal to 10% of the shares converted from time to time under the SIV Convertible Notes, with the warrants having an exercise price equal to the corresponding conversion price at the time of issuance.

On December 5, 2025, the Company amended the October 2024 Convertible Note (the "December 2025 Amendment"). The December 2025 Amendment, among other things, deferred the first payment tranche of $1.0 million principal, originally due December 1, 2025, to May 1, 2026, and all remaining accrued unpaid interest, originally due March 1, 2026, to May 1, 2026. It also delayed the date on or after which the Company may incur up to $4.0 million of additional indebtedness pari passu with the October 2024 Convertible Note from December 1, 2025, to March 1, 2026.

In addition, in connection with the December 2025 Amendment, the Company issued to SIV warrants to purchase up to 13,446 shares of Class A common stock with an exercise price of $14.10 per share (the "December 2025 SIV Warrants"). The December 2025 SIV Warrants had a fair value of $0.1 million which was accounted for as a debt modification cost for the October 2024 Convertible Note. The December 2025 SIV Warrants are exercisable immediately after issuance and expire five years from the date of issuance. The Company determined the fair value of the December 2025 SIV Warrants by using a BSM option pricing model, with the following assumptions:

effective interest rates of 13% and 27% for the first and second tranches of the October 2024 Convertible Note, respectively.

During the year ended December 31, 2025, the Company converted $1.2 million of principal and $0.3 million of accrued interest on the July 2024 Convertible Note and the October 2024 Convertible Note into 77,087 shares of Class A common stock. Other than the conversion on May 20, 2025 discussed above, the conversions were accounted for under ASC Sub-Topic 470-20, with no gain or loss recognized. The Company paid $0.1 million to pay off the July 2024 Convertible Note in December 2025.

As of December 31, 2025, the October 2024 Convertible Note has a carrying value of $2.4 million, consisting of principal of $2.4 million, net unamortized discount of $0.03 million, and accrued interest of $0.3 million. The October 2024 Convertible Note has future scheduled maturities of $2.4 million in 2026. For the year ended December 31, 2025, interest recognized on the SIV Convertible Notes totaled $0.1 million. This amount consists of cash interest expense of $0.5 million partially offset by non-cash amortization of net debt premiums of $0.4 million. For the year ended December 31, 2024, interest recognized on the SIV Convertible Notes totaled $0.2 million. This amount consists of cash interest expense of $0.1 million partially offset by non-cash amortization of net debt discounts of $0.1 million.

***Term Loan***

On February 22, 2021, the Company entered into a Term Loan and Security Agreement (the "Term Loan") with Western Technology Investment which provided the Company with up to $40.0 million in borrowing capacity at an annual interest rate of 12.0%. The Company borrowed $25.0 million of the Term Loan at inception of the agreement on March 1, 2021. The remaining $15.0 million of borrowing capacity is no longer available as the Company did not achieve certain milestones by the June 30, 2021, deadline. The repayment terms of the Term Loan provide for interest-only payments from March 1, 2021, through February 28, 2022.

Under the original terms, the principal amount was due and payable on March 1, 2022. However, during January 2022 the Company exercised its option to pay back the principal amount of the Term Loan over two years beginning on March 1, 2022, and ending on February 28, 2024.

The Company allocated the proceeds from the Term Loan agreement to the note and warrants issued in conjunction with the Term Loan comprising the financing agreement based on the relative fair value of the individual securities on the February 22, 2021, closing date of the agreements. The discount attributable to the note, an aggregate of $15.8 million, primarily related to the value of the warrant liability with immaterial issuance costs, was amortized using the effective interest method over the term of the note, originally maturing on March 1, 2022, but amended to being repaid over two years, recorded as interest expense. Because the discount on the note exceeds 62.6% of its initial face value, and because the discount is amortized over the period from issuance to maturity, the calculated effective interest rate up until January 2022 was 126.0%.

As a result of the exercised extended repayment schedule, the unamortized discount and issuance costs were recast over the updated term of the loan and resulted in a recalculated effective interest rate of 28.2%. Interest expense amortization related to the Term Loan was zero and $0.05 million for the years ended December 31, 2025 and 2024, respectively.

In January 2024, the Company repaid the remaining principal balance of the Term Loan.

***Common Stock and Preferred Stock***

Effective December 17, 2025, the Company's stockholders approved a 1-for-17.85 reverse stock split of the Company's Class A common stock. As a result of the reverse stock split, every 17.85 shares of Class A common stock issued and outstanding on December 17, 2025, were automatically combined into one share of Class A common stock. Any fractional shares resulting from the reverse stock split were rounded up to the next nearest whole share of Class A common stock.

In addition to the reverse stock split implemented in December 2025, the Company previously effected a 1-for-14 reverse stock split of the Company's Class A common stock on December 12, 2024, whereby every 14 shares of

Class A common stock issued and outstanding on December 12, 2024, were automatically combined into one share of Class A common stock. Any fractional shares resulting from the reverse stock split were rounded up to the next nearest whole share of Class A common stock.

To effectuate the December 2025 1-for-17.85 reverse stock split, the Company filed a Certificate of Amendment to the Second Amended and Restated Certificate of Incorporation, as amended. As a result of the reverse stock split, there was no change to par value and the total number of authorized shares of Class A common stock.

Pursuant to the terms of the Second Amended and Restated Certificate of Incorporation, as amended, the Company is authorized and has available a total of 270,000,000 shares of stock, consisting of (i) 250,000,000 shares of Class A common stock, par value $0.00001 per share, (ii) — shares of Class B common stock, par value $0.00001 per share, and (iii) 20,000,000 shares of Series A preferred stock, par value $0.00001 per share.

Each share of Series A preferred stock is non-voting and convertible, at the option of the holder thereof, at any time and from time to time, and without the payment of additional consideration by the holder thereof, into 0.56 shares of Class A common stock. The Series A preferred stock is senior to the Company's common stock with respect to dividends and liquidation distributions. In the event of a liquidation, dissolution, or winding up of the Company, holders of Series A preferred stock are entitled to receive, before any payment to common stockholders, the greater of the $20.80 per share of Series A preferred stock or the as-converted value based on conversion into shares of Class A common stock. Holders are entitled to dividends on an as-converted basis, proportionate to any dividends declared on common stock, which are discretionary and non-cumulative. The Series A preferred stock is classified as permanent equity under ASC Topic 480, as it is not mandatorily redeemable and lacks redemption triggers outside of a final liquidation event.

Also on the effective date of the reverse stock split, all options, warrants and other convertible securities of the Company outstanding immediately prior to the reverse stock split were adjusted by dividing the number of shares of Class A common stock into which the options, warrants and other convertible securities were exercisable or convertible by 17.85 and multiplying the exercise or conversion price thereof by 17.85, all in accordance with the terms of the plans, agreements or arrangements governing such options, warrants and other convertible securities and subject to rounding to the nearest whole share. Such proportional adjustments were also made to the number of shares and RSUs issued and issuable under the Company's equity compensation plan.

The Company has retroactively adjusted all periods presented for the effects of the December 2025 1-for-17.85 reverse stock split.

***Shares issued in settlement of accounts payable and customer deposits***

During the year ended December 31, 2025, excluding the Baker & McKenzie LLP settlement discussed below, the Company settled $0.4 million of accounts payable and one deposit with several vendors and one customer, respectively, through the issuance of 14,737 shares of Class A common stock. The fair value of the shares issued was determined to be $0.4 million based on the closing price of the Class A common stock on the settlement dates and no gain or loss on extinguishment was recognized as fair value was equal to the carrying amount of the liabilities settled.

***December 2025 Warrant Inducement***

On December 9, 2025, the Company entered into a warrant inducement agreement (the "December 2025 Warrant Inducement") with an investor who was holding the August 2025 Warrants (see discussion of the August 2025 Warrant Inducement below). Pursuant to the December 2025 Warrant Inducement, on December 9, 2025, the investor agreed to exercise for cash all 272,385 of the August 2025 Warrants at an exercise price of $13.74 per share. The investor paid gross proceeds of $3.7 million, before deducting offering fees and other expenses of $0.3 million payable by the Company. Prior to entering into the December 2025 Warrant Inducement, the August 2025 Warrants were immediately exercisable at an exercise price of $19.81 per share. Net proceeds of $3.4 million from the exercise of the August 2025 Warrants was recorded to additional paid-in capital.

The Company determined the fair value of the August 2025 Warrants immediately before and after modification by using a BSM option pricing model and the inducement exercise price of $13.74 per share, respectively, and determined an incremental increase in fair value of approximately $1.5 million. In accordance with ASC Topic 815 guidance on equity classified warrant modifications, the incremental change in fair value of the August 2025

The Company agreed to issue new warrants to purchase up to 408,577 shares of Class A common stock, with an exercise price of $13.74 per share (the "December 2025 Warrants"), in consideration of the investor's agreement to exercise the August 2025 Warrants. The December 2025 Warrants were exercisable immediately after issuance and expire five years from the date of issuance. The December 2025 Warrants meet the requirements for equity classification. The Company determined the fair value of the December 2025 Warrants at issuance by using a BSM option pricing model, with the following assumptions:

The Company may not effect the exercise of certain December 2025 Warrants, and the investor will not be entitled to exercise any portion of any such December 2025 Warrant, which, upon giving effect to such exercise, would cause the aggregate number of shares of Class A common stock beneficially owned by the investor of such December 2025 Warrants (together with its affiliates) to exceed 4.99% of the number of shares of Class A common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of such December 2025 Warrants.

In connection with the December 2025 Warrant Inducement, the Company also agreed to amend the October 2025 Warrants (see discussion of the October 2025 Warrant Inducement below) to purchase up to an aggregate of 418,466 shares of Class A common stock at an exercise price of $25.53 per share. Prior to amendment, the October 2025 Warrants had a termination date of October 15, 2030. The October 2025 Warrants were amended on December 9, 2025, to have a reduced exercise price of $13.74 per share and will expire five years from the date of stockholder approval.

The Company estimated the fair value of the October 2025 Warrants immediately before and after modification using the BSM option pricing model and determined an incremental increase in fair value of approximately $0.6 million. In accordance with ASC Topic 815 guidance on equity classified warrant modifications, the incremental change in fair value of the October 2025 Warrants was accounted for as an additional equity issuance cost for the December 2025 Warrant Inducement, which was recorded to additional paid-in-capital.

***Baker & McKenzie LLP Settlement***

On September 30, 2025, the Company entered into a General Release and Settlement Agreement (the "Settlement Agreement") with Baker & McKenzie LLP ("B&M") to settle an obligation of $1.1 million owed by the Company to B&M.

Pursuant to the Settlement Agreement, the Company agreed to (i) pay B&M $0.1 million in cash and (ii) enter into a Securities Purchase Agreement (the "B&M SPA") to issue to B&M 32,527 Class A common stock and pre-funded warrants to purchase 19,210 shares of Class A common stock (the "B&M Pre-funded Warrants"). The B&M Pre-funded Warrants have an exercise price of $0.00001 per share and are exercisable any time after the issuance,

and will not expire until exercised. The Company evaluated the issuance of the B&M Pre-funded Warrants under ASC Topic 718 and determined that they are equity classified and should be measured at their grant-date fair value, with the related expense recognized immediately upon issuance, as the underlying services were fully rendered prior to grant. The fair value of the shares and B&M Pre-funded Warrants issued was determined to be $1.2 million, based on the closing price of the Class A common stock on the settlement date, resulting in $0.1 million of additional expense recognized for the difference between the fair value shares and pre-funded warrants and the carrying amount of the liability settled.

***September 2025 Equity Line of Credit***

As part of the September 2025 Private Placement, on September 25, 2025, the Company entered into an equity purchase agreement (the "ELOC") with an investor and a registration rights agreement, pursuant to which the Company has the right, but not the obligation, to direct the investor to purchase up to $50.0 million in shares of Class A common stock, subject to certain limitations and conditions set forth in the ELOC, including the requirement that the trading price of the Class A common stock as listed on Nasdaq is at or above 106% of the purchase price, with a purchase price of $22.13 per share to be paid by the investor. The Company will control the timing and amount of any sale of shares pursuant to the ELOC.

The term of the ELOC began on September 25, 2025, and will end on the earlier of (i) the date on which the investor shall have purchased shares of Class A common stock equal to $50.0 million, (ii) 36 months from September 30, 2025, the date the Registration Statement on Form S-3 was declared effective, (iii) written notice of termination by the Company to the investor (which shall not occur at any time that the investor holds any of the shares of Class A common stock purchased under the ELOC, or within 30 days of the sale to the investor of shares of Class A common stock pursuant to the ELOC), or (iv) written notice of termination by the investor to the Company. The ELOC represents a forward contract for the sale of Class A common stock and the Company will record sales of the Class A common stock under the ELOC as they occur.

In consideration for the investor's execution and delivery of, and performance under, the ELOC, the Company issued prefunded warrants to purchase 37,816 shares of Class A common stock (the "ELOC Pre-funded Warrants"). The ELOC Pre-funded Warrants have an exercise price of $0.00001 per share and are exercisable any time after issuance, and will not expire until exercised. Unless the ELOC is terminated by January 26, 2026, the number of exercisable prefunded warrants will increase to 42,017 shares. The ELOC Pre-funded Warrants are liability classified. The ELOC Pre-funded Warrants were initially measured at a fair value of $0.8 million on the issuance date, based on the closing price of the Class A common stock on the issuance date, with a corresponding allocation from the proceeds of the September 2025 Private Placement (see Note 8).

The ELOC Pre-funded Warrants liability is recorded at fair value and marked-to-market each reporting period with changes in fair value being reflected in earnings. On November 21, 2025, the Company issued 37,816 shares of Class A common stock as a result of all of the ELOC Pre-funded Warrants being exercised and the Company received an immaterial amount of cash proceeds. The Company recognized $0.4 million in change in fair value of warrant liability in the consolidated statements of operations during the year ended December 31, 2025, related to the ELOC Pre-funded Warrants prior to exercise and, upon exercise, $0.4 million was recorded to additional paid-in capital.

On December 23, 2025, the Company entered into a First Amendment to the ELOC (the "ELOC Amendment") with the investor. The ELOC Amendment modified the purchase price mechanism for shares issuable upon delivery of a put notice from a fixed price of $1.24 per share to a variable price equal to 94% of the lowest trading price of the Class A common stock reported during the three consecutive trading days commencing on the date the applicable put notice is delivered. No shares were sold under the ELOC, as amended, during the year ended December 31, 2025.

***At-The-Market Offering***

On September 19, 2025, the Company entered into an At-the-Market Equity Offering Sales Agreement with AGP (the "ATM Sales Agreement"). Pursuant to the ATM Sales Agreement, the Company may sell, from time to time, at its option, up to $7.4 million in aggregate principal amount of an indeterminate amount of shares of the Class A common stock through AGP acting as sales agent. If the Company's public float increases such that it may sell additional amounts under the ATM Sales Agreement and the Registration Statement (as defined below), the

**MOMENTUS INC.**

**NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS**

**Note 9. Stockholders' Equity (Deficit)** (cont.)

Company may file supplements to the prospectus included in the Registration Statement prior to making additional sales.

Any shares of Class A common stock to be offered and sold under the ATM Sales Agreement will be issued and sold (i) by methods deemed to be an "at-the-market offering" as defined in Rule 415(a)(4) promulgated under the Securities Act, or in negotiated transactions, if authorized by the Company, and (ii) pursuant to, and only upon the effectiveness of, a Registration Statement on Form S-3 filed by the Company with the SEC on September 22, 2025 for an offering of up to $50.0 million of various securities, including shares of the Company's Class A common stock, preferred stock, debt securities, warrants and/or units for sale to the public in one or more public offerings (the "Registration Statement"). Under the ATM Sales Agreement, AGP will be entitled to compensation at a commission rate of up to 3.0% of the gross sales price per share sold.

On October 10, 2025, October 20, 2025, and December 12, 2025, the Company filed prospectus supplements to the Registration Statement increasing the aggregate principal amount to $9.2 million, $13.0 million, and $17.4 million, respectively. During the year ended December 31, 2025, the Company issued 757,193 shares of Class A common stock under the ATM Sales Agreement for gross proceeds of $13.6 million, before deducting estimated issuance costs of $0.5 million. The Company subsequently filed additional prospectus supplements to the Registration Statement increasing the aggregate principal amount (see Note 17).

The sales of Class A common stock under the ATM Sales Agreement triggered the downround provisions for each of the previously issued December 2024 Wolverine Warrants, Initial Tranche Warrants, and Second Tranche Warrants on December 2, 2025, December 19, 2025, and December 31, 2025. The Company recorded an aggregate deemed dividend of $0.1 million as a result of these downround adjustments, which were calculated using the BSM option pricing model with the following assumptions:

Pursuant to the August 2025 Warrant Inducement, on August 13, 2025, the investor agreed to exercise for cash (i) 71,367 of the February 2025 Warrants at an exercise price of $19.81 per share and (ii) 64,826 of the remaining Investor Modified Warrants at an exercise price of $19.81 per share. The investor paid gross proceeds of $2.7 million, before deducting offering fees and other expenses of $0.3 million payable by the Company. Prior to entering into the August 2025 Warrant Inducement, the February 2025 Warrants and Investor were immediately exercisable at an exercise price of $67.83 per share and $25.17 per share, respectively. Net proceeds of $2.4 million from the exercise of the February 2025 Warrants and the Investor Modified Warrants was recorded to additional paid-in capital.

The Company determined the fair value of the February 2025 Warrants and the Investor Modified Warrants immediately before modification by using a BSM option pricing model and immediately after modification by using the inducement exercise price of $19.81 per share. The Company determined there was a decrease in the fair value of the February 2025 Warrants and the Investor Modified Warrants. In accordance with ASC Topic 815 guidance on equity classified warrant modifications, a decrease in fair value is not recognized. The significant inputs into the BSM option pricing model immediately before the modification date are as follows:

***July 2025 Public Offering***

On July 01, 2025, the Company consummated a "best efforts" public offering (the "July 2025 Offering") of an aggregate of (i) 38,096 shares of Class A common stock at a purchase price of $25.17 per share, (ii) pre-funded warrants (the "July 2025 Pre-funded Warrants") to purchase 120,834 shares of Class A common stock, and (iii) warrants to purchase 158,925 shares of Class A common stock (the "July 2025 Warrants").

The purchase price of each July 2025 Pre-funded Warrant was equal to the price per share of Class A common stock being sold in the July 2025 Offering minus $0.00001. The July 2025 Pre-funded Warrants have an exercise price of $0.00001 per share and are exercisable any time after the issuance, and will not expire until exercised. The July 2025 Warrants have an exercise price per share of Class A common stock equal to $25.17 per share and will expire five years from the date of issuance. The July 2025 Offering closed on July 01, 2025. Both the July 2025 Pre-funded Warrants and the July 2025 Warrants meet the requirements for equity classification.

The Company received aggregate gross proceeds from the July 2025 Offering of approximately $4.0 million, before deducting issuance costs of $0.6 million. Net proceeds of $3.4 million from the July 2025 Offering was recorded to additional paid-in-capital.

In connection with the July 2025 Offering, the Company entered into a Securities Purchase Agreement with a single institutional investor, pursuant to which the Company agreed not to effect or enter into an agreement to effect any issuance by the Company or any of its subsidiaries of shares of common stock or common stock equivalents for a period of 45 days and will not effect or enter into an agreement to effect any issuance by the Company or any of its subsidiaries of shares of common stock or common stock equivalents (or a combination of units thereof) involving a variable rate transaction for a period of 3 months after July 1, 2025, subject to certain exceptions.

The Company estimated the fair value of the July 2025 Pre-funded Warrants based on the fair value of the Company's Class A common stock from the issuance date, less the $0.00001 exercise price.

Also in connection with the July 2025 Offering, the Company agreed to amend the remaining Investor Modified Warrants still outstanding (see discussion of the March 2025 Warrant Inducement below) to purchase up to an aggregate of 64,826 shares of Class A common stock.

Upon amendment, each of the Investor Modified Warrants had a reduced exercise price of $25.17 per share and a termination date of July 1, 2030.

The Company estimated the fair value of the Investor Modified Warrants immediately before and after modification using the BSM option pricing model and determined an incremental increase in fair value of approximately $0.4 million. In accordance with ASC Topic 815 guidance on equity classified warrant modifications, the incremental change in fair value of the Investor Modified Warrants was accounted for as an additional equity issuance cost for

***Master Services Agreement with Velo3D, Inc.***

On April 12, 2025, the Company entered into a Master Services Agreement (the "MSA") with Velo3D, Inc. ("VLD"), a provider of additive manufacturing solutions, also referred to as 3D printing, pursuant to which VLD will provide services to design and produce components and systems that will be utilized by the Company or its customers in its spacecraft, systems, and components. The MSA has a term of five years and provides the Company with priority access to manufacturing capacity equivalent to approximately $3,000,000 annually, corresponding to the output of two Sapphire XC 3D metal printers or comparable equipment. If the Company does not fully utilize this capacity in a given year, it may receive credits equal to 20% of the unused value (net of service fees paid) in the first year and 50% thereafter. The Company has an option to purchase the equipment after the second anniversary of the MSA at 70% of its amortized value.

In exchange for the services, the Company issued an aggregate of 26,749 shares of Class A common stock and 673,408 shares of Series A preferred stock. The grant-date fair value of the equity issued was determined to be $10.7 million, based upon the enterprise value of the company on the date of the transaction and considering the quoted market price of the Class A common stock on the issuance date for the common shares issued and, for the Series A preferred stock, an as-converted basis using the same closing price adjusted for its conversion ratio and features. A Discount for Lack of Marketability ("DLOM") was applied to the aggregate valuation. This discount was determined based on certain assumptions, including a volatility rate of 45.0% per year and a length of holding period restriction of 0.5 years. The Company evaluated the issuance of these shares under ASC Topic 718 and determined that shares were equity classified and, at contract inception, there was no recognition required related to the MSA as no goods or services had been delivered.

The credit provision related to unused capacity was determined to be an embedded derivative under ASC Topic 815 (the "Credit Provision Derivative"). The Credit Provision Derivative was bifurcated from the contract and is recorded at fair value and marked-to-market each reporting period with changes in fair value being reflected in earnings. As of the inception date, the Credit Provision Derivative was valued at zero.

On August 14, 2025, the Company irrevocably waived its right under the MSA to cancel shares of the Company's capital stock held by VLD upon expiration or termination of the MSA (the "VLD Amendment"). The shares of Series A preferred stock held by VLD are fully vested and non-forfeitable. This amendment was accounted for as a Type I Modification under ASC Topic 718 and the Company recognized the grant-date fair value of $10.7 million immediately as a prepaid asset. Of the $10.7 million recognized on August 14, 2025, $2.1 million was recorded within prepaids and other current assets and $8.6 million was recorded within other non-current assets in our consolidated balance sheets. As only term that changed as a result of the VLD Amendment was related to vesting, there was no change in fair value of the equity issued as a result of the amendment and no incremental fair value recognized. The prepaid asset will be amortized to expense over the 5 year period of the MSA as services are provided to the Company.

**Note 9. Stockholders' Equity (Deficit)** (cont.)

On October 17, 2025, VLD converted 126,000 shares of the Company's Series A preferred stock into 70,588 shares of Class A common stock.

During the year ended December 31, 2025, the Company only received $0.1 million out of the $3.0 million annual prepayment of services from VLD. The Company determined that $1.7 million of the prepaid services will not be utilized in the first annual period of the MSA and are thus not recoverable as of December 31, 2025. As a result, $1.7 million of prepaid design and productions services were written off and recognized as an impairment loss in selling, general and administrative expenses in the consolidated statements of operations during the year ended December 31, 2025. In relation to this underutilization of prepaid services, the recognized loss was partially offset by $0.2 million of other income recognized in other expense in the consolidated statements of operations during the year ended December 31, 2025, for a recognized increase in the fair value of the Credit Provision Derivative of $0.2 million as of December 31, 2025. The Credit Provision Derivative asset is recorded in prepaids and other current assets in the consolidated balance sheets.

***March 2025 Warrant Inducement***

On March 20, 2025, the Company entered into a warrant inducement agreement (the "March 2025 Warrant Inducement") with an investor who was holding the Investor Modified Warrants (see discussion of the February 2025 Offering below). Pursuant to the March 2025 Warrant Inducement, on March 21, 2025, the investor agreed to exercise for cash 60,025 of the Investor Modified Warrants at an exercise price of $34.45 per share. The investor paid gross proceeds of $2.1 million, before deducting offering fees and other expenses of $0.2 million payable by the Company. Prior to entering into the March 2025 Warrant Inducement, the Investor Modified Warrants were immediately exercisable at an exercise price of $67.83 per share. Net proceeds of $1.9 million from the exercise of the Investor Modified Warrants was recorded to additional paid-in capital.

The Company agreed to issue new warrants to purchase up to 120,049 shares of Class A common stock, with an exercise price of $35.70 per share (the "March 2025 Warrants"), in consideration of the investor's agreement to exercise the Investor Modified Warrants. The March 2025 Warrants were exercisable immediately after issuance and expire five years from the date of issuance. The March 2025 Warrants meet the requirements for equity classification.

The Company may not effect the exercise of certain March 2025 Warrants, and the investor will not be entitled to exercise any portion of any such March 2025 Warrants, which, upon giving effect to such exercise, would cause the aggregate number of shares of Class A common stock beneficially owned by the investor of such March 2025 Warrants (together with its affiliates) to exceed 4.99% of the number of shares of Class A common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of such March 2025 Warrants.

On March 24, 2025, only 18,544 shares of Class A common stock were delivered to the investor due to beneficial ownership limitations upon the exercise of the Investor Modified Warrants. The remaining 41,481 shares were subsequently delivered to the investor during the year ended December 31, 2025.

***February 2025 Public Offering***

On February 11, 2025, the Company consummated a "best efforts" public offering (the "February 2025 Offering") of an aggregate of (i) 16,807 shares of Class A common stock at a purchase price of $70.06 per share, (ii) pre-funded warrants (the "February 2025 Pre-funded Warrants") to purchase 54,560 shares of Class A common stock, and (iii) warrants to purchase 71,367 shares of Class A common stock (the "February 2025 Warrants").

The purchase price of each February 2025 Pre-funded Warrant was equal to the price per share of Class A common stock being sold in the February 2025 Offering minus $0.00001. The February 2025 Pre-funded Warrants have an exercise price of $0.00001 per share and are exercisable any time after the issuance, and will not expire until exercised.

of the January 2024 Warrants using the BSM option pricing model. The significant inputs into the BSM option pricing model at the initial recognition date are as follows:

---

In connection with the January 2024 Offering, the Company agreed to amend each of the warrants issued in November 2023 to purchase up to an aggregate of 23,244 shares of Class A common stock at an exercise price of $964.61 per share (the "November 2023 Modified Warrants"). Prior to amendment, the November 2023 Modified Warrants had a termination date of November 9, 2028. The November 2023 Modified Warrants were amended on May 9, 2024, to have a reduced exercise price of $136.02 per share and a termination date of May 9, 2029.

The Company estimated the fair value of the November 2023 Modified Warrants immediately before and after modification using the BSM option pricing model and determined an incremental increase in fair value of approximately $1.2 million. In accordance with ASC Topic 815 guidance on equity classified warrant modifications, the incremental change in fair value of the November 2023 Modified Warrants was accounted for as an additional equity issuance cost for the January 2024 Offering, which was recorded to additional paid-in-capital. The significant inputs into the BSM option pricing model before and after the modification date are as follows:

---

| | | |
|:---|:---|:---|
| | **Pre-modification** | **Post-modification** |
| Expected term (years) | 4.83 | 5.00 |
| Volatility | 97.50% | 97.50% |
| Risk-free rate | 3.85% | 3.84% |
| Dividend yield | 0.00% | 0.00% |

---

Subsequent to the January 2024 Offering, during the year ended December 31, 2024, the Company issued 11,153 shares of Class A common stock as a result of all of the January 2024 Pre-funded Warrants being exercised and the Company received an immaterial amount of cash proceeds.

***Public and Private Warrants***

As of December 31, 2025, the Company had Public and Private Warrants outstanding to purchase 691 shares and 903 shares of Class A common stock, respectively, related to the Business Combination. The warrants entitle the registered holder to purchase stock at a price of $143,693 per share, subject to adjustment, at any time commencing on August 12, 2021. The Public and Private Warrants expire on the fifth anniversary of the Business Combination, or earlier upon redemption or liquidation.

The Private Warrants assumed in connection with the Business Combination are accounted for as a derivative liability. The Public Warrants and the legacy outstanding Private Warrants were recorded as equity within the consolidated statements of stockholders' equity (deficit).

***Contingent Sponsor Earnout Shares***

As a result of the Business Combination, the Company modified the terms of 116 shares of Class A common stock held by SRAC's sponsor (the "Sponsor Earnout Shares"), such that all such shares will be forfeited if the share price of Class A common stock does not reach a volume-weighted average closing sale price of $156,188, two thirds of such shares will be forfeited if the share price of Class A common stock does not reach a volume-weighted average closing sale price of $187,425, and one third of such shares will be forfeited if the share price of Class A common stock does not reach a volume-weighted average closing sale price of $218,663, in each case, prior to the fifth anniversary of the Business Combination. Certain events which change the number of outstanding shares of Class A common stock, such as a split, combination, or recapitalization, among other potential events, will equitably adjust the target vesting prices above. The Sponsor Earnout Shares may not be transferred without the Company's consent until the shares vest.

**Note 9. Stockholders' Equity (Deficit)** (cont.)

The Sponsor Earnout Shares are recorded within equity. Due to the contingently forfeitable nature of the shares, the Sponsor Earnout Shares are excluded from basic EPS calculations but are considered potentially dilutive shares for the purposes of diluted EPS (refer to Note 11).

**Note 10. Stock-based Compensation**

***Legacy Stock Plans***

In May 2018, the Board of Directors of Momentus Inc. approved the 2018 Stock Plan (the "Initial Plan") that allowed for granting of incentive and non-qualified stock options ("NSOs") and restricted stock awards ("RSAs") to employees, directors, and consultants. The Initial Plan was terminated in November 2018. Awards outstanding under the Initial Plan continue to be governed by the terms of the Initial Plan.

In February and March 2020, the Board of Directors of Momentus Inc. approved the Amended and Restated 2018 Stock Plan (the "2018 Plan"). No additional grants have been made since 2020 and no new grants will be made from the 2018 Plan, however, the options issued and outstanding under the plan continue to be governed by the terms of the 2018 Plan. Forfeitures from the legacy plans become available under the 2021 Equity Incentive Plan, described below.

***2021 Equity Incentive Plan***

In 2021, the Company adopted the 2021 Equity Incentive Plan (the "2021 Plan"), under which 479 shares of Class A common stock were initially reserved for issuance. The 2021 Plan allows for the issuance of incentive stock options, NSOs, RSAs, stock appreciation rights ("SARs"), RSUs, and performance awards. The Board of Directors determines the period over which grants become exercisable. The 2021 Plan became effective immediately following the Closing. The 2021 Plan has an evergreen provision which allows for shares available for issuance under the plan to be increased on the first day of each fiscal year beginning with the 2022 fiscal year and ending on (and including) the first day of the 2031 fiscal year, in each case, in an amount equal to (i) three percent (3.0%) of the outstanding shares on the last day of the immediately preceding fiscal year or (ii) such number of shares determined by the Board of Directors.

On May 19, 2025, the Company adopted the first amendment to the 2021 Plan to increase the number of shares of Class A common stock available for issuance under the 2021 Plan by 53,222 shares. All other terms of the 2021 Plan remained the same.

During the year ended December 31, 2025, the shares available for grant under the 2021 Plan increased by 57,871 due to the evergreen provision and increases approved by the Board of Directors and 2 due to forfeitures. As of December 31, 2025, there were 18,980 shares remaining available for grant. Grant activity under the 2021 Plan is described below.

***2021 Employee Stock Purchase Plan***

In connection with the Closing, the Company adopted the Employee Stock Purchase Plan (the "2021 ESPP"), under which 128 shares of Class A common stock were initially reserved for issuance. The 2021 ESPP provides a means by which eligible employees of the Company may be given an opportunity to purchase shares of Class A common stock at a discount as permitted under the Internal Revenue Code of 1986, as amended. The 2021 ESPP has an evergreen provision which allows for shares available for issuance under the plan to be increased on the first day of each fiscal year beginning with the 2022 fiscal year and ending on (and including) the first day of the 2031 fiscal year, in each case, in an amount equal to (i) half a percent (0.5%) of the outstanding shares on the last day of the calendar month prior to the date of such automatic increase or (ii) 128 shares. Participation in the 2021 ESPP has been suspended by the Board of Directors. The 2021 ESPP became effective immediately following the Closing. The Company has an outstanding liability pertaining to the 2021 ESPP of $4 thousand as of December 31, 2025, included in accrued expenses, for employee contributions to the 2021 ESPP, which will be refunded to participants due to the suspension of the plan. As of December 31, 2025, there were 194 shares remaining available for issuance.

***2022 Inducement Equity Plan***

In February 2022, the Company adopted the 2022 Inducement Equity Plan (the "2022 Plan"), under which 321 shares of Class A common stock were initially reserved for issuance. The 2022 Plan allows for the issuance of

NSOs, RSAs, SARs, RSUs, and stock bonus awards, subject to certain eligibility requirements. The Board of Directors determines the period over which grants become exercisable and grants generally vest over a four-year period.

On March 22, 2023, the Company adopted the first amendment to the 2022 Plan to increase the number of shares of Class A common stock available for issuance under the 2022 Plan from 321 shares of Class A common stock to 561 shares of Class A common stock. All other terms of the 2022 Plan remained the same.

On May 8, 2023, the Company adopted the second amendment to the 2022 Plan to increase the number of shares of Class A common stock available for issuance under the 2022 Plan from 561 shares of Class A common stock to 641 shares of Class A common stock. All other terms of the 2022 Plan remained the same.

During the year ended December 31, 2025, the shares available for grant under the 2022 Plan increased by 14,000 due to increases approved by the Board of Directors. As of December 31, 2025, only RSU grants have been made under the 2022 Plan and there were 6,360 shares remaining available for issuance. Grant activity under the 2022 Plan is described below.

**Note 11. Net Loss Per Share**

Net loss per share is provided in accordance with ASC Sub-Topic 260-10, *Earnings Per Share*. Basic earnings per share is computed by dividing net loss for the period by the weighted-average number of common shares outstanding during the period. Diluted earnings per share gives effect to all dilutive potential common shares outstanding during the period. It is computed by dividing undistributed earnings allocated to common stockholders for the period by the weighted average number of common shares outstanding during the period, plus the dilutive effect of outstanding preferred shares, options and unvested stock units, and warrants outstanding pursuant to the treasury stock method.

As the Company incurred a net loss for the years ended December 31, 2025 and 2024, the inclusion of preferred stock, certain options, unvested stock units, warrants, convertible promissory notes, and contingent Sponsor Earnout Shares in the calculation of diluted earnings per share would be anti-dilutive and, accordingly, were excluded from the diluted loss per share calculation.

The following table summarizes potential common shares that were excluded as their effect is anti-dilutive:

---

| | | |
|:---|:---|:---|
| | **Year Ended<br>December 31,** | **Year Ended<br>December 31,** |
| | **2025** | **2024** |

***Legal Proceedings***

*Securities Class Actions* 

On July 15, 2021, a purported stockholder of SRAC filed a putative class action complaint against SRAC, SRC-NI Holdings, LLC ("Sponsor"), Brian Kabot (SRAC CEO), James Norris (SRAC CFO), Momentus, and the Company's co-founder and former CEO, Mikhail Kokorich, in the United States District Court for the Central District of California, in a case captioned *Jensen v. Stable Road Acquisition Corp., et al.*, No. 2:21-cv-05744 (the "*Jensen* class action"). The complaint alleges that the defendants omitted certain material information in their public statements and disclosures regarding the Business Combination, in violation of the securities laws, and seeks damages on behalf of a putative class of stockholders who purchased SRAC stock between October 7, 2020, and July 13, 2021. Subsequent complaints captioned *Hall v. Stable Road Acquisition Corp., et al.*, No. 2:21-cv-05943 and *Depoy v. Stable Road Acquisition Corp., et al.*, No. 2:21-cv-06287 were consolidated in the first filed matter (collectively, referred to as the "Securities Class Actions"). An amended complaint was filed on November 12, 2021. The Company disputes the allegations in the Securities Class Actions.

On February 10, 2023, the lead plaintiff in the Securities Class Actions and the Company reached an agreement in principle to settle the Securities Class Actions. Under the terms of the agreement in principle, the lead plaintiff, on behalf of a class of all persons that purchased or otherwise acquired Company stock between October 7, 2020 and July 13, 2021, inclusive, would release the Company from all claims asserted or that could have been asserted in the Securities Class Actions and dismiss such claims with prejudice, in exchange for payment of $8.5 million by the Company (at least $4.0 million of which was funded by insurance proceeds).

On April 10, 2023, the parties filed a Notice of Settlement with the Court, and on August 18, 2023, the parties executed a Settlement Agreement. On August 30, 2023 the lead plaintiff filed a Motion for Preliminary Approval of Class Action Settlement, and the Court entered an Order Preliminarily Approving Settlement and Providing for Notice on September 21, 2023. Pursuant to that Order, on October 5, 2023, the Company paid $1.0 million into the settlement escrow account. On November 16, 2023, following the Court's order granting lead plaintiff's motion to enforce the settlement agreement and despite the Company's attempts to negotiate an extension of time to satisfy its payment obligations, the Company paid an additional $3.5 million into the settlement escrow account. Insurance carriers made additional payments totaling $4.0 million into the settlement escrow account.

On April 23, 2024, the Court entered an order and judgment finally approving the settlement of the Securities Class Actions. A group of plaintiffs asserting the Delaware Class Actions (see below) objected to the scope of the release in the settlement, and the Court overruled the objection. Those objectors may or may not appeal the Court's decision to overrule their objections and approve the settlement. The Company does not know the timing of when such an appeal, if filed, would be heard. If the objectors do not appeal the approval of the settlement, or if their appeal is ultimately rejected by the Court of Appeals, then the settlement will resolve all claims in the Securities Class Actions against the Company (except as to any shareholders that may elect to opt-out of the class). The Company and the other defendants have denied and continue to deny each and all of the claims alleged in the Securities Class Actions, and the proposed settlement contains no admission of liability, wrongdoing or responsibility by any of the defendants. In the event that a court, on appeal or otherwise, overturns the approval of the settlement, the Company will continue to vigorously defend against the claims asserted in the Securities Class Actions.

As a result of the agreement to settle the Securities Class Action, the Company recorded a litigation settlement contingency of $8.5 million. The Company additionally recorded an insurance receivable of $4.0 million for the insurance proceeds expected from its insurers related to the settlement. The net amount of $4.5 million was recognized in litigation settlement, net during the year ended December 31, 2022. As of December 31, 2024, the contingent liability in relation to Securities Class Action had been paid in full.

*Shareholder Derivative Litigation*

On June 20, 2022, a shareholder derivative action was filed by Brian Lindsey, on behalf of the Company, in the U.S. District Court for the Central District of California, Case No. 2:22-cv-04212, against the Company (as a nominal defendant), SRAC, Brian Kabot, Juan Manuel Quiroga, James Norris, James Hofmockel, Mikhail Kokorich, Dawn Harms, Fred Kennedy, Chris Hadfield, Mitchel B. Kugler, Victorino Mercado, Kimberly A. Reed, Linda J. Reiners, and John C. Rood. This derivative action alleges the same core allegations as stated in the Securities Class Actions litigation. The defendants dispute the allegations as stated in this derivative action. On September 27, 2022, the plaintiff filed his Notice of Voluntary Dismissal without Prejudice seeking to dismiss the case. Because the plaintiff's dismissal of this derivative action was voluntary and without prejudice, this plaintiff and/or other shareholders may seek to re-file the claims asserted in this matter at a later date. As noted below, Brian Lindsey re-filed a shareholder derivative action in Delaware Chancery Court on June 30, 2023.

On January 25, 2023, a shareholder derivative action was filed by Melissa Hanna, on behalf of the Company, in the U.S. District Court for the Northern District of California, Case No. 5:23-cv-00374, against the Company (as a nominal defendant), SRAC, Brian Kabot, Juan Manuel Quiroga, James Norris, James Hofmockel, Mikhail Kokorich, Dawn Harms, Fred Kennedy, Chris Hadfield, Mitchel B. Kugler, Victorino Mercado, Kimberly A. Reed, Linda J. Reiners, and John C. Rood (the "Derivative Action II"). The Derivative Action II alleges the same core allegations as stated in the Securities Class Actions, and also claims that the Company ignored and/or refused a prior demand made by Ms. Hanna on the Company's Board of Directors. The Company intends to vigorously defend the litigation.

On April 25, 2023, a shareholder derivative action was filed by Justin Rivlin, purportedly on behalf of the Company, in the U.S. District Court for the District of California, Case No. 2:23-cv-03120, against the Company (as a nominal defendant), Brian Kabot, James Norris, Marc Lehmann, James Hofmockel, and Ann Kono. The *Rivlin* derivative action alleges the same core allegations as stated in the Securities Class Actions. The Company has filed a motion to dismiss the complaint on the grounds that the claims are time-barred and that the plaintiff was not excused from making a demand on the Company before filing the lawsuit. The Company intends to vigorously defend the litigation. On August 4, 2023, the plaintiff in the *Rivlin* action responded to the Company's motion to dismiss by filing an amended complaint adding new claims and new defendants, including existing Board members Chris Hadfield, Mitchel B. Kugler, Kimberly A. Reed, Linda J. Reiners, and John C. Rood.

On June 30, 2023, a shareholder derivative action was filed by Brian Lindsey, purportedly on behalf of the Company in the Court of Chancery for the State of Delaware (Case No. 2023-0674), against the Company (as a nominal defendant), Juan Manuel Quiroga, James Norris, James Hofmockel, Stable Road Acquisition Corp., SRC-NI Holdings, LLC, Mikhail Kokorich, Brian Kabot, Dawn Harms, Fred Kennedy, Chris Hadfield, Mitchel B. Kugler, Victorino Mercado, Kimberly A. Reed, Linda J. Reiners, and John C. Rood. The *Lindsey* derivative action alleges the same core allegations as stated in the Securities Class Actions. The Company intends to vigorously defend the litigation.

On August 26, 2024, an unopposed motion for the preliminary approval of settlement was filed after the Company reached an agreement in principle for a proposed settlement of certain shareholder derivative litigation. The proposed settlement, as set forth more fully in the Stipulation and Agreement of Settlement filed with the court, requires the Company to adopt certain corporate governance reforms. The reforms must be maintained for a minimum period of four years.

On September 16, 2024, the U.S. District Court for the Northern District of California issued an order primarily approving the settlement and providing for notice of the settlement to stockholders of the Company in the matters captioned *Hanna v. Kabot, et al.*, Case No. 5:23-cv-00374 (N.D. Cal.); *Rivlin v. Kabot, et al.*, Case No. 2:23-cv-03120 (C.D. Cal.); *Lindsey v. Quiroga, et al.*, Case No. 20230674 (Del. Ch.); and the litigation demand made by Momentus stockholder, Kamal Qureshi (collectively, the "Derivative Matters"). The proposed settlement calls for the Company to adopt certain corporate governance reforms and pay lead plaintiffs' attorney's fees, litigation expenses, and lead plaintiff service awards.

The order set a final approval hearing for November 21, 2024, and the U.S. District Court for the Northern District of California approved the settlement agreement, including the dismissal with prejudice of all claims against the defendants, via Order dated January 10, 2025. The matter was fully covered under the Company's insurance policy, and all associated legal fees and settlement costs were paid directly by the insurer. As a result, the Company did not incur any expenses related to legal fees or settlement costs in connection with this matter.

*SAFE Note Litigation*

On July 20, 2022, The Larian Living Trust ("TLLT") filed an action against the Company in New Castle County Superior Court, Delaware, in the Complex Commercial Litigation Division, Case No. N22C-07-133 EMD CCLD. TLLT pleads claims for fraudulent inducement and breach of contract arising from two investment contracts pursuant to which TLLT alleges it invested $4.0 million in the Company. TLLT alleges that a "liquidity event" occurred when the Company closed the Business Combination, such that it was entitled to the greater of its $4.0 million investment or its "Conversion Amount" of the Company's shares, which was a total of 59 shares of the Company's stock. TLLT further alleges that the Company refused to provide it the conversion amount of shares until April 2022, at which point the value of its shares had dropped significantly from their peak value in August of 2021, in excess of $7.6 million. TLLT seeks damages in excess of $7.6 million, in addition to interests and its attorney's fees and costs. On March 16, 2023, the Company's motion to dismiss TLLT's claims was denied and the parties will move forward with discovery. On July 13, 2023, the Company filed a motion for partial summary judgment. The hearing on the Company's motion for partial summary judgment was set for November 8, 2023, TLLT filed an Answering Brief on September 15, 2023, and the Company filed a Reply Brief on October 16, 2023. On January 31, 2024, the Superior Court denied the Company's motion for partial summary judgment. The Company disputes the allegations in the complaint and intends to vigorously defend the litigation. The Company and TLLT have held settlement discussions, but an agreement in principle has not been finalized. On April 30, 2025, the Court entered an order stating that the matter would be dismissed for want of prosecution if no proceedings are undertaken within 30 days of that date. No such proceedings have been instituted by the plaintiff after the filing of that order.

*Founder Litigation* 

On June 8, 2021, former co-founders and shareholders of the Company, Mikhail Kokorich and Lev Khasis, signed the NSA alongside stock repurchase agreements, whereby they agreed to divest their interests in the Company in exchange for a cash payment and other considerations. As part of the NSA and stock repurchase agreements, Messrs. Kokorich and Khasis agreed to a broad waiver and release of all claims (broadly defined) against the Company. The Company has maintained that this release is effective as to various advancement and indemnification claims either individual may have against the Company.

Both Messrs. Kokorich and Khasis have, through counsel, disagreed with the Company's position. For example, Mr. Kokorich is named as a defendant in the securities class action pending against the Company and other defendants, although he has not been served nor appeared in those matters. In addition, Mr. Kokorich is the sole defendant in a civil litigation action filed against him by the SEC in the U.S. District Court for the District of Columbia, Case No. 1:21-cv-01869. On November 25, 2024, the U.S. District Court for the District of Columbia entered a final consent judgment in the SEC's civil action against Mr. Kokorich (Case No. 1:21-cv-01869), resolving all claims in that proceeding. Mr. Kokorich has demanded indemnification and advancement from the Company for his fees and costs incurred in these actions, which claims are disputed by the Company.

The Company continues to maintain that Mr. Kokorich's release in the NSA and stock repurchase agreements is effective as to his claims for advancement and indemnification in these litigation matters. On August 16, 2022, Mr. Kokorich filed a verified complaint against the Company in the Delaware Court of Chancery (Case No. 2022-0722) seeking indemnification and advancement from the Company. Following the Company filing a motion to dismiss this action, on November 14, 2022, Mr. Kokorich filed an amended complaint. Additional motions to dismiss and replies were filed and considered at a hearing on February 2, 2023.

Mr. Khasis indemnification litigation will not be stayed pending the appeal of the Kokorich claim. Moreover, the Court of Chancery further ordered the parties to prepare a scheduling order to the Court which includes all relevant deadlines to argue the Company's motion to dismiss and Mr. Khasis' expedited motion for advancement concurrently.

In response to the Court's request for a status update, the Plaintiff moved to voluntarily dismiss its complaint without prejudice, which Momentus did not oppose. On November 26, 2024, the Court granted plaintiff's motion.

On March 5, 2026, Lev Khasis filed a verified complaint against the Company in Delaware Court of Chancery (Case No. 2026-0179-DG) seeking indemnification and advancement expenses from the Company in connection with the NSA and investigation by the Securities and Exchange Commission. Legal counsel to Khasis indicated that total expenses for which Khasis seeks indemnification is approximately $1.2 million plus legal expenses in connection with this suit. The Company believes it is probable that it can settle this claim for an amount of approximately $0.4 million. The Company is attempting to resolve these claims, but there can be no assurances a resolution will be achieved.

*Delaware Class Actions*

On November 10, 2022, purported stockholders filed a putative class action complaint against Brian Kabot, James Hofmockel, Ann Kono, Marc Lehmann, James Norris, Juan Manuel Quiroga, SRC-NI Holdings, LLC, Edward K. Freedman, Mikhail Kokorich, Dawn Harms, Fred Kennedy, and John C. Rood in the Court of Chancery of the State of Delaware, in a case captioned *Shirley, et al. v. Kabot et al.*, 2022-1023-PAF (the "*Shirley* Action"). The complaint alleges that the defendants made certain material misrepresentations, and omitted certain material information, in their public statements and disclosures regarding the Proposed Transaction, in violation of the securities laws, and seeks damages on behalf of a putative class of stockholders who purchased SRAC stock on or before August 9, 2021. On December 23, 2024, by stipulation and order of dismissal, Mr. Rood was dismissed from the complaint without prejudice.

On March 16, 2023, purported stockholders of the Company filed a putative class action complaint against certain current and former directors and officers of the Company in the Delaware Court of Chancery, in a case captioned *Lora v. Kabot, et al.*, Case No. 2023-0322 (the "*Lora* Action"). Like the *Shirley* complaint, the complaint alleges that the defendants made certain material misrepresentations, and omitted certain material information, in their public statements and disclosures regarding the Business Combination in violation of the securities laws, and seeks damages on behalf of a putative class of stockholders who purchased SRAC stock on or before August 9, 2021.

On March 17, 2023, purported stockholders of the Company filed a putative class action complaint against certain current and former directors and officers of the Company in the Delaware Court of Chancery, in a case captioned *Burk v. Kabot, et al.*, Case No. 2023-0334 (the "*Burk* Action"). Like the *Lora* and *Shirley* complaints, the *Burk* complaint alleges that the defendants made certain material misrepresentations, and omitted certain material information, in their public statements and disclosures regarding the Business Combination in violation of the securities laws, and seeks damages on behalf of a putative class of stockholders who purchased SRAC stock on or before August 9, 2021.

On May 26, 2023, plaintiffs filed a stipulation and proposed order for consolidation and appointment of co-lead plaintiffs and co-lead plaintiffs' counsel designating the complaint filed in the *Lora* Action as the operative complaint. On June 30, 2023, the defendants each filed a motion to dismiss the complaint. On October 26, 2023, plaintiffs filed their answering briefs in opposition to the motions to dismiss, and the defendants' reply briefs were due to be filed on or before December 14, 2023, and a hearing on the motions to dismiss was held for February 1, 2024.

On May 29, 2024, the court issued its orders on the motions to dismiss: (1) granting the motions to dismiss with respect to defendants Fred Kennedy and Dawn Harms and dismissing the claims against them with prejudice, and (2) with respect to the SRAC Defendants, granting the motion to dismiss with prejudice. However, the court noted that defendants Brian Kabot, James Hofmockel, and James Norris did not move to dismiss the portion of Count II relating to alleged misrepresentations concerning the value of SRAC shares issued in the merger and defendant Brian Kabot did not move to dismiss the portion of Count III relating to the same. As such, the claims as to the SRAC Defendants were dismissed with prejudice, except for these remaining claims.

**MOMENTUS INC.**

**NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS**

**Note 12. Commitments and Contingencies** (cont.)

The *Shirley* Action, the *Lora* Action, and the *Burk* Action have been consolidated under the caption, In re *Momentus Inc. Stockholders Litigation*, C.A. No. 2022-1023-PAF (Del Ch. Nov. 10, 2022). These putative class actions do not name the Company as a defendant. Regardless, the SRAC directors and officers, together with current and former directors and officers of the Company, have demanded indemnification and advancement from the Company, under the terms of the merger agreement and the exhibits thereto, the Delaware corporate code, the Company's Bylaws, and their individual indemnification agreements. The Company may be liable for the fees and costs incurred by the defendants and has an obligation to advance such fees during the pendency of the litigation. The Company understands that the defendants dispute the allegations in the complaint and intend to vigorously defend against any such litigation.

ANV Global Services Inc. ("ANV"), the insurer who issued a Side-A directors and officers liability insurance policy that provides coverage for the SRAC directors and officers, has asserted a claim against the Company for indemnification of certain former SRAC directors and officers in connection with a lawsuit captioned *In re Momentus, Inc. Stockholders Litigation*, No. 2023-0322, pending in the Delaware Court of Chancery (the "Consolidated Delaware Action"). ANV has requested reimbursement of $1.2 million for defense costs paid and contribution to a global settlement and has indicated it is prepared to file suit if a settlement is not reached. The Company has made a settlement offer of $0.1 million in shares of Class A common stock to each of the three former SRAC directors and officers subject to the Consolidated Delaware Action. Discussions with ANV and the affected individuals are ongoing, but there can be no assurances a resolution will be achieved.

*Indemnification Claims*

On July 31, 2024, certain former employees of the Company obtained a legal judgment in the amount of $0.5 million inclusive of interest and expenses related to claims for the advancement and reimbursement of certain legal expenses of the former employees. The Company paid the former employees $0.5 million in September 2024.

*Lease Restoration*

The Company entered a lease for office space at 1762 Automation Parkway, San Jose, California 95131 in December 2025. The Company has leased a facility at 3901 North First Street, San Jose, California 95134 ("3901") that expires on March 31, 2026. The Company intends to vacate 3901 on or before lease termination.

Under the sublease for 3901, the Company has an obligation to restore certain modifications prior to termination of the lease. The Company is unable to complete these restorations on that timeline and is negotiating with the sublandlord and the landlord regarding a financial settlement. The Company believes that it is probable that it will be required to pay a yet-to-be-determined amount of restoration costs. Total restoration costs should not exceed $0.7 million to $0.8 million based on construction proposals received by the Company and the sublandlord. However, the Company's obligation to restore certain alterations is subject to the landlord's having designated such alterations for removal at the time the landlord approved the Company's alteration plans. The Company has requested documentation from the landlord to evidence the Company's restoration obligations. The Company has not yet received such documentation. The Company has recorded an asset retirement obligation ("ARO") of $0.5 million related to these restoration costs, which it believes represents the low end of the range of possible loss.

The landlord has presented a construction proposal for $1.4 million and is claiming additional damages. The Company disputes the landlord's construction proposal and any additional damages.

The Company is attempting to resolve these claims, but there can be no assurances a resolution will be achieved.

*Other Litigation and Related Matters*

These and other litigation matters may be time-consuming, divert management's attention and resources, cause the Company to incur significant defense and settlement costs or liability, even if we believe the claims asserted against us are without merit. We intend to vigorously defend against all such claims. Because of the potential risks, expenses and uncertainties of litigation, as well as claims for indemnity from various of the parties concerned, we may from time to time settle disputes, even where we believe that we have meritorious claims or defenses. Because litigation is inherently unpredictable, further compounded by various claims for indemnity which may or may not be fully insured, we cannot assure that the results of these actions, either individually or in the aggregate, will not have a material adverse effect on our consolidated operating results and financial condition.

**Note 12. Commitments and Contingencies** (cont.)

From time to time, the Company may be a party to litigation and subject to claims incident to the ordinary course of business or in connection with the matters discussed above. Although the results of litigation and claims cannot be predicted with certainty, the Company currently believes that the final outcome of these matters will not have a material adverse effect on its business. Regardless of the outcome, litigation can have an adverse impact on the Company because of judgment, defense and settlement costs, diversion of management resources and other factors. At each reporting period, the Company evaluates whether or not a potential loss amount or a potential range of loss is probable and reasonably estimable under ASC 450-20. Legal fees are expensed as incurred.

*Accrued Loss Contingencies*

As of December 31, 2025, the Company has recorded accruals for certain probable loss contingencies and an ARO. These include $0.4 million accrued for the Khasis claim, $0.3 million for the ANV claim, and a $0.5 million ARO recognized for the 3901 sublease. The $0.7 million of probable loss contingencies are recorded in litigation settlement contingency in the consolidated balance sheets, and the $0.5 million ARO is recorded in other current liabilities in the consolidated balance sheets. The Company believes these accruals are adequate based on information currently available.

**Note 13. Income Taxes** (cont.)

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company's deferred tax assets and liabilities are as follows:

---

| | | |
|:---|:---|:---|

Management regularly assesses the ability to realize deferred tax assets recorded based upon the weight of available evidence, including such factors as recent earnings history and expected future taxable income on a jurisdiction by jurisdiction basis. In the event that the Company changes its determination as to the amount of realizable deferred tax assets, the Company will adjust its valuation allowance with a corresponding impact to the provision for income taxes in the period in which such determination is made. The Company's management believes that, based on a number of factors, it is more likely than not, that all or some portion of the deferred tax assets will not be realized; and accordingly, for the year ended December 31, 2025 the Company has provided a valuation allowance against the Company's U.S. net deferred tax assets. The net change in the valuation allowance for the year ended December 31, 2025 was an increase of $6.5 million.

As of December 31, 2025, the Company had net operating loss carryforwards for federal and state income tax purposes of $259.6 million and $103.4 million, respectively, which will begin to expire in 2037, with $246.9 million of the Company's federal net operating loss carryforward lasting indefinitely. As of December 31, 2024, the Company had federal and state net operating loss carryforwards of $202.6 million and $79.6 million, respectively. As of December 31, 2025, the Company had federal and California research and development credit carryforwards of $4.0 million and $3.1 million, respectively. As of December 31, 2024, the Company had federal and California research and development credit carryforwards of $4.0 million and $3.1 million, respectively. The federal research and development credit carryforwards will begin to expire in 2039, while the California research and development credits carry forward have an indefinite life.

The Internal Revenue Code of 1986, as amended, imposes restrictions on the utilization of net operating losses in the event of an "ownership change" of a corporation. Accordingly, a company's ability to use net operating losses may be limited as prescribed under Internal Revenue Code Section 382 ("IRC Section 382"). Events which may cause limitations in the amount of the net operating losses that the Company may use in any one year include, but are not limited to, a cumulative ownership change of more than 50% over a three-year period. Utilization of the federal and state net operating losses may be subject to substantial annual limitation due to the ownership change limitations provided by the IRC Section 382 and similar state provisions.

As of December 31, 2025 and 2024, the total amount of gross unrecognized tax benefits was $1.8 million and $1.8 million, respectively, including no interest and penalties. As of December 31, 2025, none of the total unrecognized tax benefits, if recognized, would have an impact on the Company's effective tax rate. The Company's policy is to

recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. There were no changes in uncertain tax positions during the years ended December 31, 2025 and 2024.

The Company files income tax returns in the U.S. federal and various state jurisdictions with varying statutes of limitations. The Company is generally no longer subject to tax examinations for years prior to 2021 for federal purposes and 2020 for state purposes, except in certain limited circumstances.

Before Vigoride 3 launch, the Company was in start-up phase and had no revenue recognized as of May 31, 2022. Under Section 195(b), all the expenses other than R&D, taxes and interest income/expense must be capitalized and amortized from the date the Company starts active trade or business. The Company began active trade or business as of June 1, 2022 and amortized Section 195(b) costs for the remainder of the year. As of December 31, 2025 and 2024, the Company has Section 195(b) gross deferred tax assets of $64.2 million and $69.8 million, respectively.&nbsp;&nbsp;&nbsp;&nbsp;

***One Big Beautiful Bill Act***

On July 4, 2025, a budget and reconciliation package known as the One Big Beautiful Bill Act (the "OBBBA") was signed into law in the United States. Among other provisions, the OBBBA amends U.S. tax law including the permanent extension of certain expiring provisions of the 2017 Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027.

**Note 14. Related Party Transactions** 

*Related Party Promissory Notes*

On June 21, 2024, the Company issued six promissory notes for an aggregate amount of $0.5 million to participating directors and an officer of the Company. The proceeds from the notes were used to pay for employee retention payments, working capital, and general corporate expenses. Each note issued bore an annual interest rate of 5.12% equal to the minimum applicable federal rate published by the Internal Revenue Service for June 2024. Each note held a maturity date of September 30, 2024, and was secured by the Company's assets. Principal and interest payments were due by the maturity date and the notes would have become immediately due upon the occurrence of certain customary event of default, including failure to pay amounts owing when due and/or certain events involving a discontinuation of our business or certain types of proceedings involving insolvency, bankruptcy, receivership and the like. On September 12, 2024, the six promissory notes were repaid in full to the participating directors and officer of the Company.

 **Note 15. Segment Information**

The Company operates as one operating segment. The Company's CODM is its Chief Executive Officer, who reviews financial information presented on a consolidated basis. The CODM uses consolidated net loss and net cash used in operations to assess financial performance and allocate resources. These financial metrics are used by the CODM to make key operating decisions, such as the allocation of budget between research and development and selling, general and administrative expenses and determination of cash from financing activities required.

**Note 17. Subsequent Events** 

***January 2026 Securities Purchase Agreement***

On January 5, 2026, the Company entered into a Securities Purchase Agreement for a private placement of securities. The private placement closed on January 6, 2026, resulting in aggregate gross proceeds of approximately $5.0 million, before deducting placement agent commissions and offering expenses.

Pursuant to the agreement, the Company issued (i) pre-funded warrants to purchase an aggregate of 925,926 shares of Class A common stock at an exercise price of $0.00001 per share (exercisable immediately and with no expiration date until fully exercised), and (ii) Class A common warrants to purchase an aggregate of 925,926 shares of Class A common stock at an exercise price of $5.40 per share (exercisable following stockholder approval and expiring five years from the stockholder approval date). The securities were sold without registration under the Securities Act of 1933, as amended, in reliance on Section 4(a)(2) and Rule 506(b) thereunder.

The Company also issued placement agent warrants to AGP to purchase 46,296 shares of Class A common stock at an exercise price of $5.94 per share, exercisable beginning 180 days after the commencement of sales in the offering.

The warrants include beneficial ownership limitations (4.99% of outstanding Class A common stock or voting power) and are subject to standard adjustments for stock splits, dividends, and similar events. The Company is obligated to file a resale registration statement covering the shares issuable upon exercise of the warrants within specified timeframes.

***Convertible Note Exchange***

On January 9, 2026, the Company exchanged the May 2025 Convertible Note for a new unsecured convertible promissory note (the "January 2026 Convertible Note") with substantially similar terms, except that the conversion price on the January 2026 Convertible Note was reduced from $29.8095 to $10.00 per share of Class A

**ITEM 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure**

None.

**ITEM 9A. Controls and Procedures**

*Evaluation of Disclosure Controls and Procedures*

The Company maintains disclosure controls and procedures ("Disclosure Controls") as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act that are designed to provide reasonable assurance that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms, and that such information is accumulated and communicated to management, including the Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO"), as appropriate to allow timely decisions regarding required disclosure.

In designing and evaluating the Disclosure Controls, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives and management was required to apply judgment in evaluating its controls and procedures. All internal control systems, no matter how well designed, have inherent limitations, including the possibility of human error and the circumvention of overriding controls.

In connection with the preparation of this report, our management, under the supervision and with the participation of our CEO and CFO, conducted an evaluation of the effectiveness of the design and operation of our Disclosure Controls as of December 31, 2025. Based on this evaluation, the CEO and CFO concluded that the Company's Disclosure Controls were effective as of December 31, 2025.

Our management, including our CEO and CFO, has concluded that the consolidated financial statements included in this Annual Report on Form 10-K fairly present, in all material respects, our financial condition, results of operations and cash flows for the periods presented in conformity with GAAP.

*Management's Report on Internal Control Over Financial Reporting*

The Company's management, including the Company's CEO and CFO, is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). The Company's internal control over financial reporting is a process designed to provide reasonable assurance to our management and board of directors regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP.

Internal control over financial reporting includes policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect transactions and dispositions of assets of the Company; (ii) provide reasonable assurances that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal controls over financial reporting may not prevent or detect misstatements. All internal control systems, no matter how well designed, have inherent limitations, including the possibility of human error and the circumvention of overriding controls. Accordingly, even effective internal control over financial reporting can provide only reasonable assurance with respect to financial statement preparation. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

In connection with the preparation of this report, the Company's management assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2025. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework (2013). Based on this evaluation, management concluded that the Company's internal control over financial reporting was effective as of December 31, 2025.

*Attestation Report of Registered Public Accounting Firm*

This Annual Report on Form 10-K does not include an attestation report of our independent registered public accounting firm because the Company is not an accelerated filer and not a large accelerated filer.

*Changes in Internal Control Over Financial Reporting*

During the year ended December 31, 2025, the Company remediated the material weakness in internal control over financial reporting related to misclassification errors in our accounting for certain matters that was previously reported in our Annual Report on Form 10-K for the year ended December 31, 2024, and that remained disclosed in our Quarterly Report on Form 10-Q for the quarter ended September 30, 2025. Management implemented the planned remediation steps, including the preparation of a detailed remediation plan with specific control enhancements, briefing of the Disclosure Committee and Audit Committee (and the full Board of Directors), and ongoing monitoring and testing of the enhanced controls. These remediation steps were completed during the fourth quarter of 2025. After completion of these steps, management performed testing of the remediated controls and concluded that the material weakness has been fully remediated and that internal control over financial reporting is effective as of December 31, 2025.

Other than the remediation efforts described above, there were no changes in internal control over financial reporting during the year ended December 31, 2025, that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

RE:&nbsp;&nbsp;&nbsp;&nbsp;**<u>EMPLOYMENT AGREEMENT</u>**

Dear Jon:

This Employment Agreement (the "***Agreement***") between you (referred to hereinafter as the "***Executive***" or "***you***") and Momentus Inc. (the "***Company***"), a Delaware corporation, acting through its wholly-owned subsidiary Momentus Space LLC, sets forth the terms and conditions that shall govern Executive's employment (referred to hereinafter as "***Employment***") with the Company, effective as of February 14, 2025 (the "***Effective Date***"). Executive's entire period of Employment with the Company shall be referred to hereinafter as the "***Employment Period***."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.**<u>Duties and Scope of Employment</u>.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)**<u>At-Will Employment</u>.** Executive's Employment with the Company is for no specified period and constitutes "at will" employment. Except as otherwise set forth herein, Executive is free to terminate Employment at any time, with or without advance notice, and for any reason or for no reason. Similarly, the Company is free to terminate Executive's Employment at any time, with or without advance notice, and with or without Cause (as defined below). Furthermore, although the terms and conditions of Executive's Employment with the Company may change over time, nothing shall change the at-will nature of Executive's Employment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)**<u>Position and Responsibilities</u>.** During the Employment Period, the Company agrees to employ Executive in the position of Chief Legal Officer and Corporate Secretary. Executive will report to John Rood, Chief Executive Officer, or to such other Person as the Company's Board of Directors ("***Board***") subsequently may determine ("***Executive's Supervisor***"). Subject to business travel requirements, Executive will be working primarily from

------

a remote location or such other location as the Company may request, including attending in person business meetings at the Company's offices. Executive will perform the duties and have the responsibilities and authority customarily performed and held by an employee in Executive's position for a public company registered with the SEC or as otherwise may be assigned or delegated to Executive by Executive's Supervisor.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)**<u>Obligations to the Company</u>.** During the Employment Period, Executive shall perform Executive's duties faithfully and to the best of Executive's ability and will devote Executive's full business efforts and time to the Company. During the Employment Period, without the prior written approval of Executive's Supervisor, Executive shall not render services in any capacity to any other Person and shall not act as a sole proprietor, advisor or partner of any other Person or own more than five percent (5%) of the stock of any other corporation. Notwithstanding the foregoing, Executive may serve on civic, non-profit, or charitable boards or committees, deliver lectures, fulfill speaking engagements, teach at educational institutions, or manage personal investments without advance written consent of Executive's Supervisor; provided that such activities do not individually or in the aggregate interfere with the performance of Executive's duties under this Agreement or create a potential business or fiduciary conflict. Executive shall comply with the Company's policies and rules, as they may be in effect from time to time during Executive's Employment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)**<u>No Conflicting Obligations</u>.** Executive represents and warrants to the Company that Executive is under no obligations or commitments, whether contractual or otherwise, that are inconsistent with Executive's obligations under this Agreement or that would otherwise prohibit Executive from performing Executive's duties with the Company. In connection with Executive's Employment, Executive shall not use or disclose any trade secrets or other proprietary information or intellectual property in which Executive or any other Person has any right, title or interest and Executive represents and warrants to the Company that Executive's Employment will not infringe or violate the rights of any other Person. Executive represents and warrants to the Company that Executive has returned all property and confidential information belonging to any prior employer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.**<u>Base Salary and Incentive Compensation</u>.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)**<u>Base Salary</u>.** The Company shall pay Executive, as compensation for Executive's services, a base salary at a gross annual rate of USD $450,000.00, less all required tax withholdings and other applicable deductions, in accordance with the Company's standard payroll procedures. The annual compensation specified in this Section 2(a), as modified by the Company from time to time, is referred to in this Agreement as the "***Base Salary***." Executive's Base Salary will be subject to review and adjustments that will be made based upon the Company's normal performance review practices. Effective as of the date of any change to Executive's Base Salary, the Base Salary as so changed shall be considered the new Base Salary for all purposes of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)**<u>Cash Incentive Bonus</u>.** Executive will be eligible to be considered for a discretionary annual cash incentive bonus (the "***Cash Bonus***") each calendar year during the

------

Employment Period based upon his performance in relation to certain objective and/or subjective criteria (collectively, the "***Performance Goals***"), as determined by the Company in its sole discretion. The Performance Goals for Executive's Cash Bonus for a particular year will be established by, and in the sole discretion of, the Board or any Compensation Committee of the Board (the "***Committee***"). The initial target amount for any such Cash Bonus will be up to 50% of Executive's Base Salary (the "***Target Bonus Percentage***"), less all required tax withholdings and other applicable deductions. The target amount of the Cash Bonus for 2025 will be prorated based on actual salary earned by Executive during 2025. The determinations of the Board or the Committee, as applicable, with respect to such Cash Bonus or the Target Bonus Percentage shall be final and binding. Executive's Target Bonus Percentage for any year subsequent to 2025 may be adjusted up or down, as determined in the sole discretion of the Board or the Committee. With the exception of calendar year 2025, when Executive shall be eligible to be considered for a Cash Bonus so long as he is consistently employed by the Company from the Effective Date through December 31, 2025, Executive shall not be eligible to be considered for a Cash Bonus based on his performance in a given year unless Executive is employed by the Company during the entire calendar year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)**<u>Equity Award</u>.** During the Employment Period, Executive shall be eligible to (a) receive paid time off ("***PTO***") in accordance with the Company's PTO policy, as it may be amended from time to time in the Company's discretion, and (b) participate in the employee benefit plans maintained by the Company and generally available to similarly situated employees of the Company, subject in each case to the generally applicable terms and conditions of the plan or policy in question and to the determinations of any Person or committee administering such employee benefit plan or policy. The Company reserves the right to cancel or change the employee benefit plans, policies and programs it offers to its employees at any time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.**<u>Employee Benefits</u>.** During the Employment Period, Executive shall be eligible to (a) receive paid time off ("***PTO***") in accordance with the Company's PTO policy, as it may be amended from time to time in the Company's discretion, and (b) participate in the employee benefit plans maintained by the Company and generally available to similarly situated employees of the Company, subject in each case to the generally applicable terms and conditions of the plan or policy in question and to the determinations of any Person or committee administering such employee benefit plan or policy. The Company reserves the right to cancel or change the employee benefit plans, policies and programs it offers to its employees at any time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.**<u>Reimbursement of Expenses</u>.** The Company will reimburse Executive for necessary and reasonable business expenses incurred in connection with Executive's duties hereunder upon presentation of an itemized account and appropriate supporting documentation, as well as Executive's compliance with the Company's generally applicable expense reimbursement policies in effect from to time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.**<u>Rights Upon Termination</u>.** Except as expressly provided in Section 6, upon the termination of Executive's Employment, by either party and for any reason, Executive shall only be entitled to: (a) any accrued but unpaid Base Salary and PTO through the date of termination, (b) all other benefits earned and expenses to be reimbursed as described in this

------

Agreement or under any Company-provided plans, policies, and arrangements, each in accordance with the governing documents and policies of any such benefits, reimbursements, plans, policies and arrangements, (c) any payments of or with respect to equity awards of the Company or any affiliate in accordance with the terms of such awards, and (d) such other compensation or benefits from the Company, if any, as may be required by law (collectively, the "***Accrued Benefits***"). All Accrued Benefits shall be paid in accordance with applicable law and the terms of the applicable plan, program or agreement (if any) governing such payment or benefit.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.**<u>Termination Benefits</u>.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)**<u>Termination Without Cause; Resignation for Good Reason</u>.** If Executive's termination of Employment with the Company occurs (i) due to termination by the Company for a reason other than Cause or (ii) due to resignation by Executive on account of Good Reason (as defined below), then, subject to Section 7, Executive will be entitled to the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)**<u>Accrued Benefits</u>.** The Company will pay Executive all Accrued Benefits.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)**<u>Severance Payment</u>.** Executive will receive continuing payments in the form of severance pay, which will total in the aggregate an amount equal to (A) 6 months of Executive's Base Salary as in effect immediately prior to the Termination Date (as defined below), plus (B) Executive's annual Cash Bonus at the Base Salary and Target Bonus Percentage as in effect immediately prior to the Termination Date, paid at 100% of the target amount, but prorated based on the days elapsed in such calendar year through the Termination Date. The severance payments described herein will be payable in approximately equal installments over a period of 6 months from Executive's Termination Date in accordance with the Company's regular payroll procedures, less all required tax withholdings and other applicable deductions. Payments pursuant to this Section 6(a)(ii) shall commence following the Release Deadline (as defined in Section 7(a)) provided that the first payment shall include any amounts that would have been paid to Executive if payment had commenced on Executive's Termination Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)**<u>Equity</u>.** The Equity Award to the extent then outstanding and unvested shall vest in full on the date on which the Release required by Section 7(a) below becomes effective; provided, however, that if Executive remains in Employment through the consummation of a Change in Control (as defined below) and if the successor to the Company or any affiliate of such successor does not agree to assume, substitute or otherwise continue the Equity Award at the time of the Change in Control, then the Equity Award shall vest in full immediately prior to, and contingent upon, the consummation of such Change in Control, even though Executive's Employment with the Company did not terminate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)**<u>Disability; Death</u>.** If Executive's termination of Employment with the Company occurs due to Executive becoming Disabled (as defined below) or due to Executive's death, then Executive or Executive's estate (as the case may be) will be entitled to:

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)**<u>Accrued Benefits</u>.** The Company will pay Executive or Executive's estate (as the case may be) all Accrued Benefits.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)**<u>Equity</u>.** The Equity Award to the extent then outstanding and unvested shall vest on the date on which the Release required by Section 7(a) becomes effective as to that number of Shares that would have vested had Executive remained in continuous Employment until the 12 month anniversary of the Termination Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)**<u>Voluntary Resignation; Termination for Cause</u>.** If Executive's termination of Employment with the Company occurs due to (i) Executive's voluntary resignation other than for Good Reason or (ii) the Company's termination of Executive's Employment with the Company for Cause, then Executive will receive the Accrued Benefits, but will not be entitled to any other compensation or benefits from the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)**<u>Exclusive Remedy</u>.** In the event of the termination of Executive's Employment with the Company (or any successor), the severance payments and benefits set forth in this Section 6 are intended to be and are exclusive and in lieu of any other rights or remedies to which Executive may otherwise be entitled, whether at law, in tort or contract, in equity, or under this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)**<u>No Duty to Mitigate</u>.** Executive will not be required to mitigate the amount of any payment or benefit contemplated by Section 6 of this Agreement, nor will any earnings that Executive may receive from any other source reduce any such payment or benefit.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.**<u>Conditions to Receipt of Termination Benefits</u>.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)**<u>Release of Claims Agreement</u>.** The receipt of any severance payments or benefits pursuant to Section 6 of this Agreement (other than Accrued Benefits) is subject to Executive (or Executive's representative, if applicable) timely signing and not revoking a separation agreement and release of claims in a form presented by the Company (the "***Release***"), which must become effective no later than the sixtieth (60th) day following Executive's Termination Date (the "***Release Deadline***"). If the Release is not effective by the Release Deadline, Executive will forfeit any right to severance payments or benefits under Section 6 of this Agreement (other than Accrued Benefits). Subject to the foregoing, to become effective, the Release must be timely executed by Executive (or Executive's representative in the event of Executive's death or Disability) and any revocation periods (as required by statute, regulation, or otherwise) must have expired without Executive (or Executive's representative, if applicable) having revoked the Release. Without regard to any special timing provisions set forth in Section 6 of this Agreement, any severance payments or benefits under Section 6 (other than Accrued Benefits) that are Deferred Payments (as defined in Section 8(a)) will be paid or commence on the first payroll date following the date on which the Release becomes effective unless the Release Deadline would have occurred in a subsequent calendar year to the date on which the Release becomes effective, in which case the severance payments and benefits that are Deferred Payments shall be paid or commence on the first payroll period of the calendar year

------

following the calendar year in which the Termination Date occurs. For the avoidance of doubt, Accrued Benefits are not subject to the provisions of this Section 7(a).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)**<u>Restrictive Covenants</u>.** The receipt of any severance payments or benefits pursuant to Section 6 (other than the Accrued Benefits) will be subject to Executive not violating the provisions of Section 11. In the event Executive breaches the provisions of Section 11, all continuing payments and benefits to which Executive may otherwise be entitled pursuant to Section 6 will immediately cease. This provision is not intended and should not be interpreted to preclude the Company from seeking and receiving all other relief, including monetary damages, to which it is entitled based upon Executive's breach of Section 11.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)**<u>Confidential Information Agreement</u>.** Executive's receipt of any severance payments or benefits under Section 6 (other than the Accrued Benefits) will be subject to Executive continuing to comply with the terms of the Confidentiality Agreement (as defined in Section 13 below).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.**<u>Section 409A</u>.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)Notwithstanding anything to the contrary in this Agreement, no severance payment or benefit to be paid or provided to Executive, if any, pursuant to this Agreement that, when considered together with any other severance payments or separation benefits, are considered deferred compensation not exempt under Section 409A (as defined below) (each, a "***Deferred Payment***") will be paid or otherwise provided until Executive has a "separation from service" within the meaning of Section 409A and for purposes of this Agreement, any reference to "termination of employment," "termination" or any similar term shall be construed to mean a "separation from service" within the meaning of Section 409A.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Notwithstanding anything to the contrary in this Agreement, if Executive is a "***specified employee***" within the meaning of Section 409A at the time of Executive's termination of Employment (other than due to death), then the Deferred Payments, if any, that are payable within the first six (6) months following Executive's separation from service, will become payable on the first payroll date that occurs on or after the date six (6) months and one (1) day following the date of Executive's separation from service. All subsequent Deferred Payments, if any, will be payable in accordance with the payment schedule applicable to each payment or benefit. Notwithstanding anything herein to the contrary, if Executive dies following Executive's separation from service, but prior to the six (6) month anniversary of the separation from service, then any payments delayed in accordance with this paragraph will be payable in a lump sum as soon as administratively practicable after the date of Executive's death and all other Deferred Payments will be payable in accordance with the payment schedule applicable to each payment or benefit. Each payment, installment and benefit payable under this Agreement is intended to constitute a separate payment for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)Without limitation, any amount paid under this Agreement that satisfies the requirements of the "short-term deferral" rule set forth in Section 1.409A-1(b)(4) of the

------

Treasury Regulations is not intended to constitute a Deferred Payment for purposes of Section 8(a) above.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)Without limitation, any amount paid under this Agreement that qualifies as a payment made as a result of an involuntary separation from service pursuant to Section 1.409A-1(b)(9)(iii) of the Treasury Regulations that does not exceed the Section 409A Limit (as defined below) is not intended to constitute a Deferred Payment for purposes of Section 8(a) above. Any payment intended to qualify under this exemption must be made within the allowable time period specified in Section 1.409A-1(b)(9)(iii) of the Treasury Regulations. "***Section 409A Limit***" means two (2) times the lesser of: (i) Executive's annualized compensation based upon the annual rate of pay paid to Executive during Executive's taxable year preceding Executive's taxable year of his or her separation from service as determined under Treasury Regulation Section 1.409A-1(b)(9)(iii)(A)(1) and any Internal Revenue Service guidance issued with respect thereto; or (ii) the maximum amount that may be taken into account under a qualified plan pursuant to Section 401(a)(17) of the Code for the year in which Executive's separation from service occurred.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)To the extent that reimbursements or in-kind benefits under this Agreement constitute non-exempt "nonqualified deferred compensation" for purposes of Section 409A, (i) all reimbursements hereunder shall be made on or prior to the last day of the calendar year following the calendar year in which the expense was incurred by Executive, (ii) any right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit, and (iii) the amount of expenses eligible for reimbursement or in-kind benefits provided in any calendar year shall not in any way affect the expenses eligible for reimbursement or in-kind benefits to be provided in any other calendar year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)The payments and benefits provided under this Agreement are intended to be exempt from or comply with the requirements of Section 409A so that none of the payments or benefits to be provided hereunder will be subject to the additional tax imposed under Section 409A, and any ambiguities or ambiguous terms herein will be interpreted to be exempt or so comply. The Company and Executive agree to work together in good faith to consider amendments to this Agreement and to take such reasonable actions that are necessary, appropriate or desirable to avoid imposition of any additional tax or income recognition prior to actual payment to Executive under Section 409A. Notwithstanding the foregoing, the Company makes no representation that any or all of the payments described in this Agreement will be exempt from or comply with Section 409A and makes no undertaking to preclude Section 409A from applying to any such payment. Executive understands and agrees that Executive shall be solely responsible for the payment of any taxes, penalties, interest or other expenses incurred by Executive on account of non-compliance with Section 409A.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9.**<u>Definition of Terms</u>.** The following terms referred to in this Agreement will have the following meanings:

For any circumstances that may constitute Cause for which Executive is entitled to an opportunity to cure pursuant to this paragraph, Executive shall only be entitled to one (1) opportunity to cure; further instances will not require additional opportunities to cure.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;&nbsp;**<u>Change in Control</u>.** "***Change in Control***" means the occurrence of any of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)The consummation of the sale, transfer or other disposition of all or substantially all of the Company's assets (other than (A) to a corporation or other entity of which at least a majority of its combined voting power is owned directly or indirectly by the Company, (B) to a corporation or other entity owned directly or indirectly by the shareholders of the Company in substantially the same proportions as their ownership of the Common Stock of the Company or (C) to a continuing or surviving entity described in Section 9(b)(i) in connection with a merger, consolidation or reorganization which does not result in a Change in Control under Section 9(b)(i);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)A change in the effective control of the Company which occurs on the date that a majority of members of the Board is replaced during any twelve (12) month period by directors whose appointment or election is not endorsed by a majority of the members of the Board prior to the date of the appointment or election; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv)The consummation of any transaction as a result of which any "person" (as defined below) becomes the "beneficial owner" (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the "***Exchange Act***")), directly or indirectly, of securities of the Company representing at least fifty percent (50%) of the total voting power represented by the Company's then outstanding voting securities. For purposes of this Section 9(b), the term "***person***" shall have the same meaning as when used in Sections 13(d) and 14(d) of the Exchange Act but shall exclude:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)a trustee or other fiduciary holding securities under an employee benefit plan of the Company or an affiliate;

A transaction shall not constitute a Change in Control if its sole purpose is to change the state of the Company's incorporation or to create a holding company that will be owned in substantially the same proportions by the persons who held the Company's securities immediately before such transaction. In addition, if any person (as defined above) is considered to be in effective control of the Company, the acquisition of additional control of the Company by the same person will not be considered to cause a Change in Control. If required for compliance with Section 409A of the Code, in no event will a Change in Control be deemed to have occurred if such transaction is not also a "change in the ownership or effective control of" the Company or "a change in the ownership of a substantial portion of the assets of" the Company as determined under Treasury Regulation Section 1.409A-3(i)(5) (without regard to any alternative definition thereunder).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)&nbsp;&nbsp;&nbsp;&nbsp;**<u>Good Reason</u>.** "***Good Reason***" means Executive's termination of Employment within 30 days after the expiration of any cure period (discussed below) following the occurrence of one or more of the following, without Executive's consent:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv)A material breach by the Company of a material provision of this Agreement.

Executive will not resign for Good Reason without first providing the Company with written notice of the acts or omissions constituting the grounds for Good Reason within sixty (60) days of the initial existence of the grounds for Good Reason and, if capable of cure, a cure period of thirty (30) days following the date the Company receives such notice during which such condition must not have been cured.

Any reduction made pursuant to this Section 10(a) shall be made in a manner determined by the Company that is consistent with the requirements of Section 409A.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)A nationally recognized certified public accounting firm selected by the Company (the "***Accounting Firm***") shall perform the foregoing calculations related to the Excise Tax. The Company shall bear all expenses with respect to the determinations by such Accounting Firm required to be made hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)The Accounting Firm engaged to make the determinations hereunder shall provide its calculations, together with detailed supporting documentation, to Executive and the Company within fifteen (15) calendar days after the date on which Executive's right to a Payment is triggered.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11.**<u>Restrictive Covenants</u>.** The agreements and obligations of Executive in this Section 11 are in addition to and not in lieu of the provisions of any other restrictive covenant agreement to which Executive is a party with the Company or its affiliates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)**<u>Non-Solicitation</u>.** During the period beginning on the Effective Date and continuing until the first anniversary of the Termination Date, Executive shall not use any trade secrets of the Company to solicit or recruit (on Executive's own behalf or on behalf of any other Person other than the Company): (i) any current employee or consultant of the Company or any of the Company's affiliates, (ii) any former employee or consultant of the Company or any of the Company's affiliates who left the Company's (or such affiliate's) service within the preceding six (6) months, or (iii) the business of any customer, supplier, lender or investor of the Company or any of the Company's affiliates.

Nothing herein is intended or should be interpreted to preclude Executive from providing truthful testimony in response to a lawfully-issued subpoena or other legal compulsion.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)**<u>Non-Disclosure</u>.** Except if required by law, Executive shall not disclose to others this Agreement or its terms, except that Executive may disclose such information to

------

Executive's spouse, and to Executive's attorney or accountant in order for such individuals to render services to Executive.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12.**<u>Arbitration</u>.** To the fullest extent permitted by applicable law, Executive and the Company agree that any and all disputes, demands, claims, or controversies ("***Claims***") relating to, arising from or regarding Executive's Employment, including Claims by the Company, Claims against the Company, and Claims against any current or former parent, affiliate, subsidiary, successor or predecessor of the Company or their or the Company's respective officers, directors, agents or employees, shall be resolved by final and binding arbitration before a single arbitrator in San Jose, California (or another mutually agreeable location). This does not prevent either Executive or the Company from seeking and obtaining temporary or preliminary injunctive relief in court to prevent irreparable harm pending the conclusion of any arbitration. This arbitration agreement does not apply to any claims that have been expressly excluded from arbitration by a governing law not preempted by the Federal Arbitration Act and does not restrict or preclude Executive from communicating with, filing an administrative charge or claim with, or providing testimony to any governmental entity about any actual or potential violation of law or obtaining relief through a government agency process. The parties hereto agree that Claims shall be resolved on an individual basis only, and not on a class, collective, or representative basis on behalf of, or along with, other employees, to the fullest extent permitted by applicable law ("***Class Waiver***"). Any claim that all or part of the Class Waiver is invalid, unenforceable, or unconscionable may be determined only by a court. In no case may class, collective or representative claims proceed in arbitration on behalf of other employees.

The parties agree that the arbitration of Claims shall be conducted by a single neutral arbitrator through JAMS in accordance with JAMS Employment Arbitration Rules and Procedures (available at www.jamsadr.com/rules-employment-arbitration). Except as to the Class Waiver, the arbitrator shall determine arbitrability. The Company will bear all JAMS arbitration fees and administrative costs in excess of the amount of administrative fees and costs that Executive otherwise would have been required to pay if the Claims were litigated in court. The arbitrator shall apply the applicable substantive law in deciding the Claims at issue. Claims will be governed by their applicable statute of limitations and failure to demand arbitration within the prescribed time period shall bar the Claims as provided by law. The decision or award of the arbitrator shall be final and binding upon the parties. This arbitration agreement is enforceable under and governed by the Federal Arbitration Act. In the event that any portion of this arbitration agreement is held to be invalid or unenforceable, any such provision shall be severed, and the remainder of this arbitration agreement will be given full force and effect. By signing this Agreement, Executive acknowledges and agrees that Executive has read this arbitration agreement carefully, is bound by it and is voluntarily and knowingly WAIVING ANY RIGHT TO HAVE A TRIAL BEFORE A COURT OR JURY OF ANY AND ALL CLAIMS SUBJECT TO ARBITRATION UNDER THIS ARBITRATION AGREEMENT.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13.**<u>Confidentiality Agreement</u>.** This Agreement is contingent upon Executive's execution and delivery to an officer of the Company of the Company's Confidential Information and Invention Assignment Agreement, a copy of which is attached hereto as Attachment A (the "***Confidentiality Agreement***"), prior to or on the Effective Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)**<u>Right to Work</u>.** For purposes of federal immigration law, Executive will be required to provide to the Company documentary evidence of Executive's identity and eligibility for employment in the United States. Such documentation must be provided to the Company within three (3) business days of the Effective Date, or Executive's Employment may be terminated for Cause.

By accepting this Agreement, Executive warrants that all information provided by Executive is true and correct to the best of Executive's knowledge, Executive agrees to execute any and all documentation necessary for the Company to conduct a background check. If any results of the background screening process prove unsatisfactory to the Company, the Company reserves the right to rescind any outstanding offer of employment or terminate Executive's Employment without severance benefits, notwithstanding any language in this Agreement to the contrary.

If any provision of this Agreement becomes or is deemed invalid, illegal or unenforceable in any applicable jurisdiction by reason of the scope, extent or duration of its coverage, then the parties specifically request such provision to be deemed amended to the minimum extent necessary to conform to applicable law so as to be valid and enforceable or, if such provision cannot be so amended, then such provision shall be stricken and the remainder of this Agreement shall continue in full force and effect. If any provision of this Agreement is rendered illegal by any present or future statute, law, ordinance or regulation (collectively, the "***Law***"), then that provision shall be curtailed or limited only to the minimum extent necessary to bring the provision into compliance with the Law.

**<u>ATTACHMENT A</u>**

**CONFIDENTIAL INFORMATION AND INVENTION ASSIGNMENT AGREEMENT**

## Exhibit 19.1

**MOMENTUS INC.**

**INSIDER TRADING POLICY**

(*Revised August 21, 2023*)

**1. Purpose**

<br> The following sets forth the policy of Momentus Inc. (the "***Company***") with respect to transactions in the Company's securities (e.g., Class A common stock), as well as the securities of publicly-traded companies with which the Company has a business relationship, for the purpose of promoting compliance with applicable securities laws by its directors, officers, employees and designated contractors.

Federal and state securities laws prohibit the purchase or sale of a company's securities by anyone who is aware of material information about that company that is not generally known or available to the public. These laws also prohibit anyone who is aware of material non-public information ("***MNPI***") from disclosing this information to others who may trade. Companies and their controlling persons may also be subject to liability if they fail to take reasonable steps to prevent insider trading by company personnel.

The penalties for insider trading include civil fines of up to three (3) times the profit gained or loss avoided, and criminal fines of up to $5 million and up to twenty years in jail for each violation. The Securities and Exchange Commission ("***SEC***") has imposed large penalties even when the disclosing person did not profit from the trading. The SEC, the stock exchanges and the Financial Industry Regulatory Authority use sophisticated electronic surveillance techniques to uncover insider trading.

**2. Covered Persons**

As a director, officer, employee or designated contractor of the Company or its subsidiaries (each, a "***Covered Person***"), this policy applies to you. The same restrictions that apply to you apply to your family members who reside with you, anyone else who lives in your household, and any family members who do not live in your household but whose transactions in the Company's securities are directed by you or are subject to your influence or control (such as parents or children who consult with you before they trade in the Company's securities); it also covers venture capital firms and other entities (such as partnerships, trusts and corporations) that are affiliated or associated with you or such persons. You are responsible for making sure that any transaction in securities covered by this policy by you or any of these people or entities complies with this policy.

An affiliate of a person subject to this policy is someone who directly or indirectly controls or is controlled by, or is under common control with such person. An associate of a person subject to this policy is (i) a corporation or organization (other than the Company or a majority owned subsidiary of the Company) of which such person is an officer or partner or is directly or indirectly the beneficial owner of 10% or more of any class of equity securities or (ii) any trust in which such person has a substantial beneficial interest or as to which such person serves as trustee or in a similar capacity.

------

Each individual is responsible for the consequences of his or her actions. You are responsible for understanding and complying with this policy. Employees of the Company who violate this policy shall also be subject to disciplinary action by the Company, which may include ineligibility for future participation in the Company's equity plans or termination of employment for cause.

The portions of this policy relating to trading while in possession of MNPI and the use or disclosure of that information continue to apply to transactions in the Company's securities even after termination of employment or association with the Company. If you are aware of MNPI about the Company when your employment or other business relationship with the Company ends, you may not trade in the Company's securities or disclose the MNPI to anyone else until that information is made public or becomes no longer material, including by waiting until the end of any blackout period or other Company-imposed trading restrictions applicable at the time of the termination of service.

**3. Definition of Material Non-Public Information**

For purposes of this policy, "***material non-public information***" or "***MNPI***" is any material information about a company that has not yet become publicly available.

Information is "material" if a reasonable investor would likely consider it important in making a decision to buy, hold or sell securities. Any information that could reasonably be expected to affect the price of the security is material. The information may be positive or negative. Financial information is frequently material, even if it covers only part of a fiscal period or less than all of the company's operations, since either of these might convey enough information about the company's consolidated results of operations to be considered material information. Other common examples of information that may be material include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• information regarding financial results, financial condition and financial forecasts, including earnings estimates or changes in previously announced earnings estimates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• significant proposed mergers, acquisitions, investments or divestitures;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• gain or loss of significant customers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes or delays in flight schedules;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• entry into, renewal, termination or changes to material contracts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• layoffs or restructurings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• cyber security incidents and data breaches;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• developments in significant litigation or government investigations or reviews;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• public or private debt or equity offerings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• significant changes in senior management;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• new product or service offerings; or

&nbsp;&nbsp;&nbsp;&nbsp;2

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• capital allocation developments, such as share repurchases and dividends.

It is not possible to define all categories of material information, and you should recognize that the public, the media and the courts may use hindsight in judging what is material. Therefore, it is important to "play it safe" and assume information is material if there is any doubt. You may also consult with the Compliance Officer. The "***Compliance Officer***" means the Company's Chief Legal Officer ("***CLO***") or the CLO's designee; provided that in the event there is no CLO, the CLO is unavailable or with respect to the application of this policy to the CLO, the Company's Chief Financial Officer or Deputy General Counsel shall be authorized to serve as the Compliance Officer or to designate another person as the Compliance Officer.

Information is "non-public" if it is not generally known or available to the public. Information may still be non-public even though it is widely known within the Company.

Release of information to the media does not immediately mean the information has become publicly available. Information is considered to be available to the public only when it has been released broadly to the marketplace (such as by a press release or an SEC filing) and the investing public has had time to absorb and evaluate it. Ordinarily, information about the Company should not be considered public until at least two full trading days have passed following its formal release to the market.

**4. Trading While in Possession of MNPI is Prohibited**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.1. &nbsp;&nbsp;&nbsp;&nbsp;You are prohibited from engaging in any transaction in the Company's securities (including gifts or other transfers without consideration, such as partnership distributions) while aware of MNPI about the Company. It makes no difference whether or not you relied upon or used MNPI in deciding to trade – if you are aware of MNPI about the Company, the prohibition applies.

This prohibition covers virtually all transactions in securities of the Company, including securities and transaction not permitted under this policy. In this regard, the term "securities" includes common stock, options to purchase common stock, debt securities, preferred stock and derivative securities, such as put and call options, warrants, swaps, caps and collars, and the term "transactions" includes purchases, sales, pledges, hedges, loans and gifts of the Company's securities, as well as other direct or indirect transfers of the Company's securities. This prohibition extends to trades of the Company's securities in which you have any "beneficial" or other interest, or over which you exercise investment control, including: (i) transactions in the Company's securities held in joint accounts or accounts of persons or entities controlled directly or indirectly by you; (ii) transactions in the Company's securities for which you act as trustee, executor or custodian; and (iii) transactions in any other account or investment involving in any way any the Company's securities over which you exercise any direct or indirect control.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.2&nbsp;&nbsp;&nbsp;&nbsp;For the avoidance of doubt, this prohibition applies to the subsequent sales of the Company's securities issued pursuant to equity awards, and the Company's Employee Stock Purchase Plan ("***ESPP***"), as well broker-assisted sales for the purpose of generating the cash needed to cover the costs of options exercises and/or tax withholding. In addition, your decision to participate in the ESPP and any decision to

&nbsp;&nbsp;&nbsp;&nbsp;3

------

change your election under the ESPP should not be made while you are in possession of MNPI.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.3&nbsp;&nbsp;&nbsp;&nbsp;You are also prohibited from engaging in transactions in securities of other companies (as broadly defined as such terms are in the second paragraph of Section 4.1) while aware of material non-public information about those companies. In particular, information learned in connection with your work on transactions or relationships between the Company and another publicly-traded company may constitute MNPI about the other company. Such MNPI may include negotiations over mergers, acquisitions, divestitures or renewal or termination of significant contracts or other arrangements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.4. &nbsp;&nbsp;&nbsp;&nbsp;These prohibitions do **not** apply to:

&nbsp;&nbsp;&nbsp;&nbsp;4.4.1.&nbsp;&nbsp;&nbsp;&nbsp;The exercise of stock options or option-like awards if the exercise price is paid in cash or through the Company withholding a portion of the shares underlying the options.

&nbsp;&nbsp;&nbsp;&nbsp;4.4.2.&nbsp;&nbsp;&nbsp;&nbsp;The Company's withholding of shares underlying equity awards to satisfy tax withholding requirements.

&nbsp;&nbsp;&nbsp;&nbsp;4.4.3&nbsp;&nbsp;&nbsp;&nbsp;The purchase of shares under the ESPP.

&nbsp;&nbsp;&nbsp;&nbsp;4.4.4&nbsp;&nbsp;&nbsp;&nbsp;Trades made pursuant to a valid "10b5-1 plan" approved by the Compliance Officer as described in Section 8 below.

&nbsp;&nbsp;&nbsp;&nbsp;4.4.5&nbsp;&nbsp;&nbsp;&nbsp;Transfers by will or the laws of descent and distribution or transfers for tax planning purposes in which your beneficial ownership and pecuniary interest in the transferred securities does not change.

&nbsp;&nbsp;&nbsp;&nbsp;4.4.6&nbsp;&nbsp;&nbsp;&nbsp;Transactions otherwise prohibited by this policy if, prior to the transaction, the Compliance Officer determines that the transaction is not inconsistent with the purposes of this policy and exceptional circumstances apply.

&nbsp;&nbsp;&nbsp;&nbsp;4.4.7&nbsp;&nbsp;&nbsp;&nbsp;The existence of a personal financial emergency does not excuse you from compliance with this policy and will not be the basis for an exception to the policy under Section 4.4.7 or otherwise for a transaction that is not inconsistent with the purposes of the policy.

**5. Disclosure of MNPI is Prohibited; No "Tipping"**

You may not disclose MNPI about the Company or any other company to others, make recommendations or express opinions to others about investments in or the prospects of the Company or those companies while in possession of this information, or otherwise make unauthorized disclosure or use of this information. Use of such information other than for legitimate business purposes of the Company violates Company policy and the terms of applicable confidentiality agreements. This practice, known as "tipping", also violates the securities laws and can result in the same civil and criminal penalties that apply to insider trading, even though you did not trade and did not gain or intend to gain any benefit from another's trading or the disclosure or use of such information.

&nbsp;&nbsp;&nbsp;&nbsp;4

------

Any written or verbal statement that would be prohibited under the law or under this policy is equally prohibited if made on electronic bulletin boards, chat rooms, blogs, websites or any other form of social media, including the disclosure of MNPI about the Company or with respect to other companies that you learn through your work with the Company.

**6. Other Prohibited Transactions** 

You and any person acting on your behalf may not:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.1&nbsp;&nbsp;&nbsp;&nbsp;Engage in short sales of the Company's securities (sales of securities that are not then owned), including "sales against the box" (short sales not exceeding the number of shares already owned).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.2&nbsp;&nbsp;&nbsp;&nbsp;Trade in derivatives of the Company's securities, such as exchange-traded put or call options and forward transactions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.3&nbsp;&nbsp;&nbsp;&nbsp;Purchase any financial instruments (such as prepaid variable forward contracts, equity swaps, collars or exchange funds) or otherwise engaging in any transactions that hedge or offset any decrease in the market value of the Company's securities or limit your ability to profit from an increase in the market value of the Company's securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.4&nbsp;&nbsp;&nbsp;&nbsp;Holding the Company's securities in a margin account or pledging the Company's securities as collateral for a loan unless the pledge has been approved by the Compliance Officer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.5&nbsp;&nbsp;&nbsp;&nbsp;Except under valid 10b5-1 plans approved by the Compliance Officer as described in Section 8 below, establish standing orders for more than three business days.

**7. Blackout Periods; Pre-clearance of Transactions**

Except under valid 10b5-1 plans approved by the Compliance Officer as described in Section 8 below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.1&nbsp;&nbsp;&nbsp;&nbsp;No Covered Person may engage in transactions in the Company's securities during a quarterly blackout period, regardless of whether they are then actually aware of MNPI.

A quarterly blackout period is in effect with respect to each quarterly earnings announcement, starting on the first day of the first month of each fiscal quarter (provided, if the first day of the month is not a business day, then the next business day) and ending when one (1) full trading day has passed following the public announcement of the Company's quarterly financial results. The Company has selected this period because it is the time when Restricted Persons are likely to have MNPI about the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.2&nbsp;&nbsp;&nbsp;&nbsp;In addition to quarterly blackout periods applicable to certain Restricted Persons, from time to time the Company or the Compliance Officer may decide to impose an event-specific blackout period on those who are aware of particular information that the Company or the Compliance Officer determines to be MNPI. This kind of blackout may be imposed in connection with a potential acquisition, a financial analyst conference, anticipated positive or negative earnings surprises or other

&nbsp;&nbsp;&nbsp;&nbsp;5

------

material developments. If you are subject to an event-specific blackout period, you may not engage in transactions in the Company's securities until notified that the blackout period has ended.

The existence of an event-specific blackout will not be generally announced. If you are covered by the event-specific blackout, you will be notified by the Compliance Officer. Any person made aware of an event-specific blackout should not disclose the existence of the blackout to anyone else.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.3&nbsp;&nbsp;&nbsp;&nbsp;Pre-clearance of Transactions

&nbsp;&nbsp;&nbsp;&nbsp;7.3.1&nbsp;&nbsp;&nbsp;&nbsp;Each Restricted Person (as defined below) must refrain from engaging in transactions in the Company's securities, even at times other than the "quarterly blackout periods" and "event-specific blackout periods" discussed above, without first submitting a request for pre-clearance to the Compliance Officer and having it approved. If you are a Restricted Person, you should submit a request prior to commencing any transaction, including but not limited to sales, purchases, option exercises, gifts or other transactions in the Company's securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If you are a Restricted Person, you will be notified from time to time by the Compliance Officer of the pre-clearance and other procedures applicable to you.

&nbsp;&nbsp;&nbsp;&nbsp;7.3.2&nbsp;&nbsp;&nbsp;&nbsp;Restricted Persons will be permitted to proceed with a proposed transaction only after the Compliance Officer has pre-cleared it and communicated his/her approval in writing or via e-mail. If you are a Restricted Person and your transaction is pre-cleared in accordance with the policy, you will then have three business days to effect the transaction (or, if sooner, before commencement of a quarterly or other blackout period), unless the Compliance Officer explicitly establishes another time period. However, under no circumstance may you engage in transactions in the Company's securities while aware of MNPI about the Company, even if pre-cleared. Thus, if you become aware of MNPI after receiving pre-clearance, but before the transaction has been executed, you must not effect the pre-cleared transaction.

&nbsp;&nbsp;&nbsp;&nbsp;7.3.3&nbsp;&nbsp;&nbsp;&nbsp;The Compliance Officer is under no obligation to approve a request under the pre-clearance procedures provided for under this policy and may determine to reject any request, even if the proposed transaction would not violate the federal securities laws or a specific provision of this policy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Approval of any request under these pre-clearance procedures does not insulate you from liability under the securities laws. Under the law, the ultimate responsibility for determining whether an individual is aware of MNPI about the Company rests with that individual in all cases.

&nbsp;&nbsp;&nbsp;&nbsp;7.3.4&nbsp;&nbsp;&nbsp;&nbsp;The Compliance Officer, in consultation with the Chief Executive Officer and the Chief Financial Officer from time to time, will designate and maintain a list of "***Restricted Persons***" for purposes of this policy. Such persons include the Company's executive officers and directors, including the Company's principal accounting officer (if separate from the

&nbsp;&nbsp;&nbsp;&nbsp;6

------

Company's principal financial officer) ("***Section 16 Persons***"), as well as others who are at an enhanced risk of possessing MNPI and who therefore must exercise greater diligence to comply with insider trading prohibitions. This latter category includes certain senior finance, legal, HR, business development, investor relations, corporate communication and management personnel in the Company's business units, as well as any other employees in a role that makes it likely they will have involvement with MNPI. **You will be notified by the Compliance Officer if you are considered a Restricted Person under this policy.**

**8.10b5-1 Plans**

SEC Rule 10b5-1(c) provides an affirmative defense to an allegation that a trade has been made on the basis of MNPI. Persons who establish written trading plans meeting the conditions of Rule 10b5-1 (commonly referred to as "***10b5-1 plans***") can avail themselves of this defense. These plans can be useful in enabling insiders to plan trading activity in advance of receiving MNPI that would prevent them from trading until it is disclosed.

Transactions executed under valid pre-approved 10b5-1 plans are not subject to the pre-clearance procedures and trading prohibitions, including the quarterly or event-specific blackout periods, under this policy.

10b5-1 plans must be entered into in advance of trading when the person is not in possession of MNPI. Furthermore, 10b5-1 plans adopted or modified by members of the Board of Directors or Section 16 Persons must include a cooling-off period ending on the later of (i) 90 days after the adoption or modification of the plan or (ii) two business days following the filing of the Form 10-Q or Form 10-K for the fiscal quarter in which the plan was adopted or modified. 10b5-1 plans adopted or modified by all other persons subject to this Policy must include a cooling-off period of at least 30 days after the adoption or modification of the plan. No transactions may occur pursuant to a 10b5-1 plan prior to the expiration of the applicable cooling-off period.

The adoption of a new 10b5-1 plan or the modification of an existing 10b5-1 plan by any person subject to this Policy must be approved in advance by the Compliance Officer, and you should allow at least five (5) business days for that approval. Persons subject to this Policy must also notify the Compliance Officer prior to terminating an existing 10b5-1 plan.

Such plans must comply with applicable guidelines established by the Compliance Officer, as may be amended from time to time, and the person establishing the 10b5-1 plan must certify to the Compliance Officer in writing, no earlier than two (2) business days prior to the date that the plan is formally established, that (i) such person is not in possession of MNPI concerning the Company; and (ii) the plan complies with the requirements of SEC Rule 10b5-1(c), including that it is being entered into in good faith and not as part of a plan or scheme to evade the prohibitions of the rule.
