Momentus is a U.S. commercial space company that plans to offeroffers transportation and infrastructure services to help enable the commercialization of space. Satellite operators are our principal customers and target customers. Services that we provide or plan to provide include “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 given our choice of water as a propellant.

Our transportation service offering will focus on delivering our customers’ satellites to precision orbits of their choosing. To accomplish this, we plan to create a hub-and-spoke transportation network in partnership with leading launch service providers, such as SpaceX. Under this model, our customers’ satellites would “ride share” from Earth to space on a midsized or large rocket. Our OTVsOSVs 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 our hub-and-spoke model

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.

In the launch market, we believe we are witnessing significant shifts caused by the emergence of large, partially reusable rockets such as SpaceX’s Falcon-9 and Blue Origin’s New Glenn, and the advent of new fully reusable vehicles such as SpaceX’s Starship and Relativity’s Terran R. Reliable, low-cost access to space is lowering the entry barriers for new service models and has allowed new entrants to grow quickly. In the future, we anticipate further disruption from a new breed of much larger, fully reusable rockets such as Starship. With these much larger rockets, launch costs could fall far enough to enable new applications that would not be economically viable with current generation launch vehicles.

Another paradigm shift in the commercial space market is the rise of the small satellite (smallsat)or “smallsat”. Prior to 2018, only a few dozen smallsats (total mass below approximately 200 kg) were launched per year. Today, the number has grown to several hundred per year and is on track to reach more than severalone thousand per year. Moreover, the rise of this market has also created a new market segment in microsatellites (total mass below approximately 100 kg) and nanosatellites (total mass below approximately 10 kg). While these satellites can be deployed individually, they can also be operated as part of a constellation, a large group of satellites interconnected to provide a service, such as the Starlink satellite constellation’s offering of global internet connectivity.

Smallsat proliferation has led operators to explore new ways of accessing space. To meet their needs, small launch providers (i.e., small rockets carrying up to approximately 500kg) have emerged as options for smaller payloads. While accessing space often costs up to ten times more per kilogram on a small rocket compared to a large rocket, such as Falcon-9, it is often uneconomical for small satellite operators to purchase a dedicated large rocket that may have up to one hundred times more payload capacity than a small rocket. “Ride sharing” on a large rocket is a more accessible option as it can drastically lower the cost for a small satellite operator to reach space, albeit with reduced deployment options compared to a dedicated launch vehicle as “ride share” payloads are often all released into the same orbit. Conversely, a dedicated small rocket, while more expensive compared to ride sharing on a larger rocket, can increase deployment options for small satellite operators by offering them direct access to precision orbits of their choosing.

We anticipate there could be 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 LEO will continue to drive overall demand growth for space transportation services in the short-term as technology advancements continue to

Beyond transportation, we anticipate that growth of the satellite constellations market may drive demand for our Hosted Payload,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 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 are developing our OTVsOSVs to provide safe, affordable, reliable, and regular in-space services to our customers, including Space Transportation, Payload Hosting,space transportation, payload hosting, and In-Orbit Servicing.in-orbit servicing. We are designinghave designed our Vigoride vehicle to deliver small customer payloads anywhere in LEO. However, we also plan to design larger vehicles to carry larger payloads to more distant orbits.

If our technology is fully developed and validated in the future, we currently plan to provide the following infrastructure services to the space economy:

Space Foundation sized the broader space economy at $469 billion in its 2022 Space Report, representing approximately 9% growth from the prior year. According to Morgan Stanley, the broader space economy is projected tocould grow from approximately $350 billion in 2016 to over $1 trillion by 2040.

Deutsche Bank estimates the current total addressable market (“TAM”) for in-space transportation to be approximately $2 billion annually, and projects this market to approximately double to $4 billion by 2025 including $2-2.5 billion for onboard satellite propulsion and $1.5-2 billion for “space tugs” (OTVs)(OSVs). While this estimate excludes launch services, we would note that we generally bundle launch services from third-party providers with our in-space transportation services.

Our primary research and development objectives focus on the development of our existing and future in-space transfer and service vehicles and related water plasma propulsion technology.

Vigoride is the first vehicle that we are developing. Once fully developed, tested and validated in space, we expect Vigoride will be sufficient to meet our initial operating plan of offering in-space transportation services to small satellites in LEO to small satellites. We plan to offer services with our Vigoride vehicle beginning as earlywell as June 2022, subject to receipt of licenses and government approvals, and successful completion of our current efforts to get the system ready for flight.payload-hosting services. The success of our in-space infrastructure services business will depend on our ability to successfully and regularly deliver customer satellites into custom orbits. We have ground-tested several Vigoride vehicles in preparation for flight, including, where appropriate, subsystem- and system level environmental testing, performance testing, and life testing in relevant environments, but weand have yet to fly anylaunched two of these vehicles ininto space.

Vigoride is intended to transport up to 750 kg of customer payload in LEO, although our payload capacity will likely be lower in most common configurations. We have set the delta-v and host power objectives for Vigoride at 2 km/sec and 1 kW, respectively, which we believe we can achieve a few years into our product roadmap.

Our planned June launch is2022 and 2023 launches were and are intended to be atest and demonstration mission.missions. While we planhave carried and will continue to take acarry relatively few paying customer payloads along,customers on these early missions, the primary goals of our inaugural mission2022 and 2023 missions were and are to test Vigoride on orbit andin space, learn from any issues that we may encounter. Theencounter and incorporate lessons learned from this initial flight will help inform changes we can make tointo future missionsVigoride vehicles as we seek to ultimately certify a design for production. While we conduct an extensive ground-test campaign to identify potential problems with each of our vehicles prior to launch, we have encountered anomalies with our vehicles and their operation in space, and we may encounter additional issues and anomalies in the future. Depending on the nature of issues and anomalies we may encounter, our schedule for future launches and other planned activities could be adversely affected. There can be no assurance that we will not experience operational or process failures and other problems during our inaugural missiontest and demonstration missions or on any other mission. Any failures or setbacks particularly on our inaugural mission, could harm our reputation and have a material adverse effect on our business, financial condition and results of operation.

Because our technologies have not yet been fully tested, our service offeringofferings to our customers onduring the test and development phase of our inaugural mission will beprogram are limited. To reflect this, we expect to provide discounts to customers on this missionthese early missions relative to the price we intend to eventually charge for our transportation services. During our inaugural mission, we plan to demonstrate Vigoride’s ability to deploy satellites at the point at which it is dropped off by the launch vehicle, rather than independently maneuver customer satellites to custom orbits. Once all customer payloads have been released, we plan to perform certain maneuvers and technology demonstrations to validate our technology and establish the potential commercial viability of our strategy. This approach limits risk for us as well as for our customers.

Early Vigoride vehicles will not be reusable, meaning that we will de-orbit them following delivery of their customer payloads. However, around the middle of this decade, we plan to make our vehicles capable of reuse such that, upon delivery of their payloads, they will be able to remain in space to conduct follow-on missions. Establishing reusable vehicles will require significant additional research and technological developments. We believe our choice of water as a propellant will help with the creation of reusable vehicles because water can be stored without special conditions, other than ensuring lines and tanks do not freeze or become obstructed with ice, for an indefinite amount of time and can be pumped easily. Additionally, water is safe and non-hazardous relative to commonly used propellants such as cryogenic components and hypergolic toxic fuels for chemical propulsion, or highly pressurized noble gases (such as Xenon or Krypton) for electrical propulsion. We believe that if we are able to achieve reusability, it will allow us to lower manufacturing and launch costs on a per-ride basis and achieve higher margins and returns for our investors while also reducing our environmental impact.

Beyond Vigoride, we envision bringing two progressively larger vehicles to market, which we call Ardoride and Fervoride.market. These vehicles will be similar to our Vigoride vehicle, but with larger structures, larger solar arrays, and more powerful propulsion systems in order to carry progressively larger payloads progressively furtherfarther from Earth.

We believe our water plasma propulsion technology can provide a competitive advantage for our vehicles and services. The technology is being designed to work as follows: Solar panels attached to our vehicle capture solar energy, which is then converted into microwave energy using standard microwave conversion technology, for which we currently use a magnetron. However, our objective is to shift to solid-state power amplifiers in the future.technology. The conversion technology then takes direct current (“DC”) power from the solar arrays and storage batteries and outputs the energy in the form of microwaves into the thrust chamber. Once in the chamber, microwave energy is transferred into the water propellant, creating steam, which is forced through a separate injector. The water is then heated into a plasma state and expelled from the thruster through a separate nozzle, thus creating a propulsive force. This propulsion is what would create motion in space.

What we believe to be unique to this technology is its potential ability to be designed for specific combinations of ISPspecific impulse (“ISP”) and thrust to improve in-space transportation operations. We believe other space propulsion technologies are unlikely to be designedable to operate atoffer the same mixbalance of ISPfuel efficiency (ISP) and delta v, resulting in each having its disadvantages for transportation missions. We believe our technology hasdelivery time (thrust) that is possible with the potential to achieve considerable propulsive thrust levels while maintaining high ISP, which would enable shorter mission duration, enhanced reach, and higher payload mass ratios.MET technology. Our objective is to evolve towards larger and more capable vehicles, and if we are successful in meeting this objective, we expect this technology’s potential capabilities to scale well. We believe modifications will revolve around research and engineering to increase the size of the water tanks, radiation-hardening for our vehicles’ components, and further scaling our thruster technology. While these potential capabilities will require significant development time and expense, we believe that our highly experienced team of engineers will help enable us to successfully enhance and scale our key technologies.

We chose water as our propellant for several reasons. We believe water is significantly safer than all chemical alternatives, allowing for safe testing and associated operating cost savings across the entire testing chain. Beyond testing, water is a safe resource that we believe will also be considerably safer in space than propellants that introduce risk of accidental combustion. Water can also be stored efficiently at low pressures and over the temperature ranges in which spacecraft equipment typically operates, subject to ensuring lines and tanks do not freeze or become obstructed with ice. This avoids the need for high-pressure tanks which themselvesmay pose an explosion hazard.

Another potential key advantage of our technology is its low cost of production and maintenance. Our engine design consists of inexpensive and readily available materials, resulting in an overall simple design and a vehicle whose propulsion, structure, avionics, and mechanisms can be efficiently and vertically integrated.

Although we believe our water plasma propulsion technology will be a key differentiator for our product offerings, to date, we have only conducted a single test of this technology in space. Although we believe our test unit generated plasma in space and validated the theoretical basis of our technology, we have yet to experimentally confirm the unit’s ability to generate thrust in space, which is crucial to our ability to perform real on-orbit maneuvers. Until we can accomplish this, the technology will remain in the experimental stages. Moreover, even if the unit generates thrust, there can be no assurance that it can be operated in a manner that is sufficiently reliable and efficient to permit full commercialization of the technology. Our statements and beliefs about the viability of our technology are primarily based on theoretical analyses and experimentally observed results during ground testing and our single test of this technology in space. Development of space technologies is extremely complex, time consuming, and

Momentus has continued to evolve and improve its microwave electro-thermal (“MET”) technology since development began in 2017. Our first-generation X-band thruster, which operatesoperated at 30 Watts, was flown aboard a demonstration mission called El Camino Real in mid-2019. During this mission, Momentus launched its first MET into space as a hosted payload on a nanosatellite. The mission’s objective was to demonstrate the MET’s ability to produce water plasma in space by performing 100 one-minute firings. The MET was instrumented with temperature, pressure and RFradio-frequency (RF) reflected power sensors to infer the presence of water plasma, which if detected, would indicate that the water propellant was flowing into the thrust chamber and radio frequency energy was being absorbed by the water. Failure of the host satellite in November 2019 prematurely terminated the demonstration after only 23 of the planned 100 firings of the thruster had been performed including 12 hot firings with microwave power turned on and 11 cold firings with the microwave turned off. While a pump issue significantly restricted flow of water into the thruster during nine of the 12 hot firings, preventing plasma-generation, the three hot firings that did have water present were found to have produced plasma. Although pressure and temperature data did not provide sufficient information to either confirm or contradict plasma presence, Momentus believes that the reflected power data collected during the three hot firings with water present to be sufficient to conclude that plasma was produced. Reflected power data collected during these three in-space firings closely matched ground test data collected by similar or identical sensors and associated with observed successful firings of the MET where water plasma was generated. We have incorporated potential solutions to the aforementioned pump issue and other observed weaknesses from El Camino Real into subsequent iterations of our propulsion system design, pressure sensor selection and vehicle integration and test process.

The Vigoride vehicle was re-designed in 2020 to increase its payload capacity. Vigoride 2 was designed to use a pair of C-band MET which would each operate at 550 Watts at the target thrust level and approximately 75% of the target specific impulse (Isp)(ISP) of our internal performance goal. This C-band thruster has undergone extensive development over the last several years. This early generation of the thruster was life tested to a reduced mission of 350 cycles (firings) and 35 hours of accumulated firing.

While Vigoride 1 and Vigoride 2 are both fully built and ground-tested, we do not currently intend to fly either vehicle in space. Both will be retained in storage and lessons learned from their production and ground-testing will be incorporated into future Vigoride vehicles that we intend to fly.

Vigoride 3 is beingwas the first OSV that the Company launched into space. It was built with an upgraded 750-Watt version of the C-band MET with the aim of producing greater thrust. Unit qualificationthrust compared to Vigoride 1 and system level functionality testing is complete, and, during the first quarter ofVigoride 2.

On May 25, 2022, the vehicle completed environmental testing in our thermal vacuum chamber, which simulates the environment in space. Our testing sequence is designed to uncover issues on the ground where we can deal with them more readily and effectively than we could in space. Over the next few weeks, the team will be addressing issues that were uncovered during thermal vacuum testing. After this, the vehicle will undergo vibration testing, which simulates the environment on the launch vehicle, and other ground tests. We expectCompany launched Vigoride 3 to low-earth orbit aboard the SpaceX Transporter-5 mission. In addition to Vigoride 3, Momentus used a second port on the same SpaceX mission to fly a third-party deployer from a partner company. On May 25, 2022, Momentus used the third-party deployer to place its first customer satellite in orbit.

While Momentus was unable to re-establish two-way communication with Vigoride 3, it continued to broadcast commands to the spacecraft from ground stations on Earth, including commands to deploy customer satellites. Additionally, Vigoride 3 was equipped with a mechanism designed to autonomously deploy customer satellites in the event of a sustained loss of communications with ground stations. Vigoride 3 deployed five additional customer satellites during July and August 2022 for a total of seven. The Company was unable and remains unable to confirm the deployment of the last two customer satellites that Vigoride 3 was carrying. In total, Momentus deployed eight customer satellites in low-earth orbit during its inaugural mission, comprising seven satellites from Vigoride 3 and one satellite from the third-party deployer system.

Vigoride 5 is the delivery of satellites using our vehicles from lower earth orbit to other orbits. The technology for this maneuver is stilllead ship in the development stageCompany’s Block 2.2 configuration, which features an upgraded propulsion system, a modular payload bay that allows fuel tanks to be substituted for customer payloads depending on specific mission requirements, upgraded payload-hosting capabilities and has not been validated...”a more efficient structural design compared to previous Vigoride vehicles. Vigoride 5 was the second OSV that the Company launched into space.

We are designing each ofhave designed our vehicles to be compatible with most rockets, and we have not entered into exclusivity arrangements with any single launch provider. We currently do not anticipate any changes to this approach, as we want to maximize our opportunities and retain the optionality to engage with other launch providers. Other advantages of maintaining a diverse set of launch partners include service resiliency in the event of launch failures and the subsequent grounding of a launch vehicle, access to otherwise protected markets through the use of specific launch vehicles and orbit diversity to provide access to all orbits of interest to our customers.

To date, we have entered into several launch services agreements including with SpaceX, Relativity Space, ABL Space Systems and Gilmour Space. Beyond these providers, we remain in active dialogue and believe we have

We believe we have developed a strong relationship with SpaceX with which we maintain an innovative rideshare partnership. We believe the relationship between our companies is recognized as mutually beneficial. We believe Momentus could unlock a market for SpaceX by consolidating small satellites on our transport vehicles once we have fully developed, tested and validated them in space, which will then be launched by SpaceX on theirits Falcon-9 rideshare missions, and delivered by Momentus to theirthe small satellites unique, respective orbits.

We believe our ability to compete successfully as a commercial provider of space transportation 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 will be unable to realize the following competitive advantages. We believe that our team’s collective expertise, coupled with the following strengths, may allow us to build our business and compete successfully.

We plan to scale and accelerate our sales and marketing efforts and leverage industry partnerships to grow our customer base using a global network of sales professionals. Additionally, if we can successfully execute on our missions, we expect existing customers to exercise contract options and expand their contracts with us for the deployment of their future satellites. We plan to provide new service offerings and sales models over time to

increase market share and grow the total addressable market for our in-space infrastructure services assuming we can successfully execute on our missions and business plan.

We anticipate the emergence of new businesses as the space economy continues to be unlocked and new applications are introduced. We plan to position ourselves to capture these emerging and adjacent markets which we believe will be enabled by the development of infrastructure services.

The regulations, policies, and guidance issued by the Federal Communications Commission (“FCC”) apply to the operation of our transport vehicles. When we communicate with our transport 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 time being, we intend to utilize the FCC’sFCC granted us a Special Temporary Authorization (“STA”) authorization type, as other rideshare aggregators, which was modified and operatorsextended for five 30-day periods at our request.Following the enactment of unique limited duration missions regularly do, to license Momentus spacecraft. Although Momentus previously submitted multiple STA license applications, which have subsequently been withdrawn, we filed STA applications at the end of 2021 in support of two spacecraft scheduled to launch in June 2022. Subsequently, we withdrew one of the two applications since it was not needed.

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 areto be subject to the licensing requirements and regulations of the National Oceanic and Atmosphere Administration's ("NOAA") Commercial Report Sensing Regulatory Affairs (“CRSRA”) office. We currently holdUntil 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. For future missions we will apply for any required NOAA authorizations on a case-by-case basis.

As a participant in launch activities, we are indirectly subject to the license requirements of the Federal Aviation Administration’s (“FAA”(the “FAA”) Office of Commercial Space Transportation (“AST”(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. During preparation for the inaugural Vigoride-1 mission, the FAA ultimately determined that it was unable to grant to SpaceX an approval of the Momentus payload for the SpaceX Transporter-1 launch in January 2021 due to national security and foreign ownership concerns regarding Momentus raised by the Department of Defense during an interagency review. Despite Momentus payloads being exempt from FAA payload review as a result of our existing NOAA grant, we initiated ongoing engagement with the FAA as part of a preemptive payload review unrelated to a launch license in contemplation of future launch activity. In May 2021, the FAA denied one of our payload review applications due to interagency concerns related to the corporate structure of Momentus at the time of denial. The FAA acknowledged that Momentus was engaged in addressing the concern and indicated that the FAA could reconsider the application once that process is complete. In March 2022, Momentus intends to refilefiled with the FAA an application for a payload review applicationsand determination in support of future missions which will reflect the ongoing efforts to address outstanding interagency concerns.Vigoride 3 mission. In May 2022, Momentus received from the FAA a favorable payload determination for the Vigoride 3 payload.

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 (“EAR”(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., for 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.

Approval of the licenses described above may be subject to interagency reviews that allow multiple government agencies — the Department of Commerce, Department of Defense, 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. As discussed above, the interagency process raised national security concerns relating to foreign ownership and control of Momentus in connection with a recent2021 FAA license application. We will continue toconstantly engage with the Department of Defense and other federal agencies to understand the steps necessary to achieve the resolution ofand address any remaining U.S. government national security concerns. No assurance can be given that we will obtain the licenses described above in this section for our future missions. Even though Momentus has entered into and implemented the NSA, there is no guarantee that the FAA and other U.S. government agencies will continue to grant the necessary authorizations.

In February 2021, Momentus and its co-founder Mikhail Kokorich, with support from Stable Road, submitted a joint notice to CFIUS for review of the historical acquisitions of interests in Momentus by Mr. Kokorich, his wife, and entities that they control in response to concerns of the U.S. Department of Defense (“DoD”(the “DoD”) regarding Momentus’ foreign ownership and control. On June 8, 2021, CFIUS’ review of the joint notice relating to historical acquisitions of interests in Momentus by Mr. Kokorich, his wife, and entities that they control concluded when the Company entered into a National Security Agreement with the U.S. government, represented by the U.S. Departments of Defense and the Treasury, and Mr. Kokorich, on behalf of himself and Nortrone Finance S.A. (an entity controlled by Mr. Kokorich), Lev Khasis and Olga Khasis, each in their respective individual capacities and on behalf of Brainyspace LLC (an entity controlled by Olga Khasis), and the U.S. government, represented by the U.S. Departments of Defense and the Treasury (the “NSA”). In accordance with the NSA, on June 8, 2021, Mr. Kokorich, Nortrone Finance S.A, Lev Khasis and his wife Olga Khasis, and Brainyspace LLC, (collectively, the “Momentus Investors”), fully divested all the shares of Momentus securities beneficially owned by them by selling shares back to Momentus. Pursuant to the NSA, a portion of those divestment proceeds were placed in escrow accounts, and may not be released to the divested investors until after completion of audit by a third partythird-party auditor of the Momentus Investors compliance with the NSA and the lapse of a 15 day period without an objection from the CFIUS Monitoring Agencies. As a subsequent event,Following the remainingthird-party audit of the investors’ NSA compliance, all of the escrowed divestment proceeds were released from escrow to the divested investors, see Note 15Co-Founders as of March 1, 2022, in accordance with the accompanying consolidated financial statements.NSA. The NSA also requires, among other things, the following:

People are our most important asset. Since its inception, Momentus has sought to recruit creative, positive persons 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 growth, we are devoting more resources to our human capital and are building the infrastructure necessary to support our workforce and promote communication, respect, and diversity among our team. We have established our Human Resources and Talent Acquisition department and have hired a Vice President to lead that group and direct our initiatives as we are deeply committed to continuing to grow and develop our team. As of December 31, 2021,2022, we had 118123 employees consisting of 8091 employees in our research and development and manufacturing teams, sevenfour employees in our sales and marketing teams and 3128 employees in general and administrative functions. 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.

DuringBeginning in 2021, we leased an approximately 65,000-square-foot facility in San Jose, California, which serves as our new headquarters, propulsion laboratory, and Vigoride assembly and test center. This space will allowallows us to quickly ramp up production volumes for Vigoride vehicles, increase available laboratory space, and accelerate thruster and other developments. We also maintain approximately 13,000 square feet of administrative, research, manufacturing, and testing facilities at our campus in Santa Clara. The campus includes a total of three office suites, two of which consist of solely offices for administrative responsibilities, research and development, and another that consists of both offices and machinery for manufacturing and testing. These facilities are pursuant to agreements through which we lease under multi-year contracts. Leases on two suites were scheduled to terminate at the end of 2021 but have been extended intoThree minor leases expired during 2022 as we continue to movecompleted the consolidation of operations to our San Jose facility, and the third is scheduled to terminate in November 2022.facility. We plan to launch our orbital vehicles in partnership with various rocket providers, including SpaceX and Relativity Space, among others. Our rocket launch partners will provide the necessary land, facility, and machinery to successfully complete the launches.

The success of our in-space infrastructure services business will depend on our ability to successfully and regularly deliver customer satellites to custom orbits. Our initial mission planned will bein May 2022 was a hybrid commercial-demonstration mission in which our vehicles willwould deliver paying customers’ satellites into orbit for the first time. In this inaugural mission, we expectWe used a third-party deployer from a partner company to demonstrate Vigoride’splace our first customer satellite in orbit. Our Vigoride spacecraft reached low-earth orbit and was able to deploy two out of nine customer satellites, but certain anomalies relating primarily to its communication and power systems limited our ability to deploycommunicate with the vehicle. Since that time, the Vigoride spacecraft has deployed five additional customer satellites, at the point at which Vigoride is dropped off by the launch vehicle. Once all client payloadsbut we have been released, we planunable to performconfirm the deployment of the remaining two customer satellites. The communication issues have also prevented Vigoride from performing orbit change maneuvers and technology demonstrations with our vehicles that arewere part of our program to validate our technology in space, and to demonstrate end-to-end in-space transfer and service operations.

the MET and identify potential refinements or upgrades for future versions of the MET in order to improve its performance. Like the ground test campaigncampaigns we have been conducting,conduct, on-orbit tests can be understood as incremental confidence-building measures — meeting key requirements for thrust, specific impulse, firing duration, lifetime and other performance parameters will help Momentus determine whether the MET is performing perin accordance with our expectations. Doing so repeatedly, both on the ground and on orbit, will demonstrate the soundness and robustness of the MET design and is expected to contribute to growing customer confidence over time. WeDespite the anomalies experienced on Vigoride 3, we are using the results of the inaugural mission, and expect to learn lessons from the first flight of Vigoride and to use the data collected from this missionfuture missions, to determine what services or level of services we will be able to initially provide customers, including the degree to which Vigoride possesses capabilities of providing customers with LEOlow-earth orbit transfer services. We anticipate that theeach mission will also lay the groundwork for continual improvements and enhancements that we plan to flight-demonstrate on future missions. We plan to offer LEOlow-earth orbit transfer services to customers in the future, based in part on the outcome of future missions and the inaugural flight and MET demonstration, as well as the results of ongoing ground testing.

The version of our Vigoride vehicle that we intend to fly on our inaugural missionare currently operating (Vigoride 5) has never been flown in space. In addition, while we have previously flown our first generation MET in space, that mission did not demonstrate the MET’s ability to generate a measured orbit change in space, which is crucial to our ability to maneuver objects in space. Moreover, even if the unit generates thrust, there can be no assurance that other systems and subsystems can be operated in a manner that is sufficiently reliable and efficient to permit full commercialization of the technology.

While the objective of the inaugural mission involving the Vigoride system is to successfully deploy satellites and perform certain maneuvers, weWe are mindful of the 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. We expect to learnhave learned and gathergathered valuable data during this inaugural mission of Vigoride as we continue to develop and improve the system and our other systems.

ThereWhile we have conducted an analysis of the root causes of the anomalies experienced by Vigoride on its inaugural mission (Vigoride 3), there can be no assurance that we will not experience operational or process failures and other problems during our inauguralongoing Vigoride 5 mission or on any other mission.during future missions. Any failures, delays or setbacks, particularly onincluding anomalies experienced in our inauguralcurrent or future mission, could harm our reputation and have a material adverse effect on our business, financial condition and results of operation.results.

While we plan to initially deliver satellites within low earthlow-earth orbit, the success of our business is in large part dependent on our ability to develop more powerful and efficient propulsion to deliver satellites and other payloads to other orbits and provide other services, such as hosted payload, deorbiting of defunct or obsolete satellites and satellite repositioning. This technology is currently under development, and if we fail to successfully complete the development and validate this technology through actual deployment and testing of such technology in space, or if we experience any delays or setbacks in the development of this technology or encounter difficulties in scaling our delivery or servicing capabilities, we may not be able to fully execute or realize our business model and our financial results and prospects would be materially adversely affected.

Additionally, as part of our business plan, we plan to provide reusable vehicles and offer in orbit services, such as hosted payload, inspection, refueling, life extension, re-positioning, salvage missions, maintenance and repair, and de-orbiting. This will require development of new capabilities for our vehicles, such as the capability to perform proximity maneuvering and berthing. These anticipated capabilities need technologies that are unproven and subject to significant continued design and development efforts, may take longer than anticipated to materialize, if at all, and may never be commercialized in a way that would allow us to generate revenue from the sale of these services and offerings. Relatedly, if such technologies become viable in the future, we may be subject to increased competition, and some competitors may have substantially greater monetary and knowledge resources than we have and expect to have in the future to devote to the development of these technologies.

We currently hold a license grant from the National Oceanic and Atmospheric Administration’s Commercial Report Sensing Regulatory Affairs (the “NOAA’s CRSRA”) office authorizing our first 10 Vigoride missions. However, we have not received a Special Temporary Authorization (“STA”) license from the FCC, and theThe FAA denied a payload

Vigoride mission (Vigoride 3). We also continue to progress toward implementation of the NSA, but there can be no assurance that our efforts will satisfy the government's national security concerns in time to obtain licenses or approvals needed for planned future missions.

U.S. government agencies other than the agency to which we apply to for a license or approval may review our applications to the FCC, FAA or other regulatory authorities, including to evaluate the national security implications of an application, which could result in delays. For example, in November 2020, the Committee for the Assessment of Foreign Participation in the United States Telecommunications Service Sector (the “Committee”) requested to review two of our FCC license applications to determine whether approval posed a risk to the national security or law enforcement interests of the United States. While in that instance, the Committee withdrew its request for review without explanation, it is possible that reviews of applications for licenses or approvals by the Committee or other regulatory bodies may occur in the future. Such reviews could delay the issuance of, or result in a denial of, licenses or approvals.

We have incurred significant losses since inception. We incurred operating losses of $99.8$91.3 million and $34.7$99.8 million for the years ended December 31, 20212022 and 2020,2021, respectively. We have not yet commenced delivery of customer satellites into orbit or fully tested and validated our technology, and it is difficult for us to predict our future operating results. As a result, our losses may be larger than anticipated, and 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.

We expect our operating expenses to increase over the next several years as we scale our operations, increase selling, general and administrative and research and development efforts relating to building corporate infrastructure to support the NSA agreement, being a public company, compliance with the NSA, new service offerings and technologies, and hire more employees. These efforts may be more costly than we expect and may not result in increased revenue or growth in our business. Any failure to increase our revenue sufficiently to keep pace with our investments and other expenses could prevent us from achieving or maintaining profitability or positive cash flow. Furthermore, if our future growth and operating performance fail to meet investor or analyst expectations, or if we have future negative cash flow or losses resulting from expanding our operations, this could have a material adverse effect on our business, financial condition and results of operations.

Our current primary research and development objectives focus on the development of our existing and future vehicles 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:

We operate in highly competitive industries and many of our competitors are larger and have substantially greater resources than we have.

We contemplate further expansion of our operations as part of our growth strategy. Our current and contemplated operations subject us to a variety of risks, including:

We have been focused on developing space transportation and infrastructure services since 2017. This limited operating history makes it difficult to evaluate Momentus’ future prospects and the risks and challenges we may encounter. Risks and challenges Momentus has faced or expects to face include our ability to:

The markets for in-space infrastructure services have not been established with precision as the commercialization of space is a relatively new development and is rapidly evolving. Our estimates for the total addressable markets for in-

As of January 31, 2022,February 28, 2023, our backlog consisted of approximately $67$33 million in customer contracts, including firm orders and options for future services. However, these 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 paid at the time the contract is signed. In certain situations, Momentus may decide to refund customers for their deposits, even though it is not contractually required, to maintain goodwill with customers.

In addition, backlog is typicallymay be subject to large variations from quarter to quarter and comparisons of backlog from period to period are not necessarily indicative of future revenues. Furthermore, some contracts comprising the backlog are for services scheduled many years in the future, and the economic viability of customers with whom we have contracted is not guaranteed over time. As a result, the contracts comprising our backlog may not result in actual revenue in any particular period, or at all, and the actual revenue from such contracts may differ from our backlog estimates. The timing of receipt of revenues, if any, on projects included in the backlog could change because many factors affect the scheduling of missions and adjustments to contracts may also occur. The failure to realize some portion of our backlog could adversely affect our revenues and gross margins. Furthermore, the presentation of our financial results requires us to make estimates and assumptions that may affect revenue recognition. In some instances, we could reasonably use different estimates and assumptions, and changes in estimates are likely to occur from period to period. Accordingly, actual results could differ significantly from our estimates.

In addition, if we do not receive regulatory approvals in a timely manner, or our future missions experience anomalies in addition to the issues experienced by our inaugural Vigoride mission (Vigoride 3), our backlog and prospects will be materially adversely affected. For example, we have experienced erosion in our backlog offrom $86 million as of March 4, 2021 to $67 million as of January 31, 2022, to $33 million as of February 28, 2023, as customers chose to cancel their contracts with us and seek alternative providers due to delays in our scheduled missions as we await receipt of necessary governmental approvals.missions. If we continue to experience delays in receiving these approvals,or future missions experience significant anomalies, we could experience further erosion in our backlog.

Currently there are only a handful of companies who offer launch services, and if this sector of the space industry does not grow or there is consolidation among these companies, we may not be able to secure space on a launch vehicle or such space may be more costly.

Our vehicles are expected to provide “last-mile” transport for satellites to their custom orbit after they are released at a drop off point in space. Therefore, we are dependent on third-party launch vehicles to deliver our vehicles into space. If the number of companies offering launch services or the number of launches does not grow in the future or there is a consolidation among companies who offer these services, this could result in a shortage of space on these launch vehicles, which may cause delays in our ability to meet our customers’ needs. Additionally, a shortage of space available on launch vehicles may cause prices to increase or cause delays in our ability to meet our customers’ needs. Either of these situations could have a material adverse effect on our results of operations and financial condition.

Further, in the event that a launch is delayed by third-party launch providers or for other reasons, our timing for revenue recognition may be impacted depending on the length of the delay and the nature of the contract with the customers with payloads on such delayed flight. For example, SpaceX delayed the December 2020 launch of Transporter-1, a Falcon 9 launch, on which our inaugural vehicle was intended to fly. Then, on May 10, 2021 and before we entered into the NSA, Momentus received a letter from the FAA denying Momentus’ application for a payload review for the planned June 2021 launch based on the FAA’s finding that its launch would jeopardize U.S. national security. While Momentus has signed a Launch Services AgreementAgreements with SpaceX to reserve space for our vehicles to be launched in June 2022,on upcoming launches, such a flight isflights are dependent on Momentus successfully completing a payload reviewreviews by the FAA.FAA for each launch.

If our operations continue to grow as planned, of which there can be no assurance, we will need to expand our sales and marketing, research and development, customer and commercial strategy, products and services, supply, and manufacturing functions. We will also need to continue to leverage our manufacturing and operational systems and processes, and there is no guarantee that we will be able to scale the business and the manufacture of vehicles as currently planned or within the planned timeframe. The continued expansion of our business may also require additional manufacturing and operational facilities, as well as space for administrative support. For example, we recently leased an approximately 65,000-square-foot facility that can accommodate the manufacture and assembly of our next generation Vigoride vehicles.

related equipment, and delays in production. These difficulties divert the attention of management and key employees and impact financial and operational results. If we are unable to drive commensurate growth, these costs, which include lease commitments, headcount and capital assets, could result in decreased margins and operating results, which could have a material adverse effect on our business, financial condition, liquidity and results of operations.

The global spread of COVID-19 has disrupted certain aspects of our operations and may continue to adversely impact our business operations and financial results, including our ability to execute on our business strategy and goals. Specifically, the continued spread of COVID-19 and new strains of the virus and precautionary actions taken related to COVID-19 have adversely impacted, and are expected to continue to adversely impact, our operations, including causing delays or disruptions in our supply chain and decreasing our operational efficiency in the development of our vehicles. We are taking measures within our facilities to ensure the health and safety of our employees, which include universal facial coverings, rearranging facilities to follow social distancing protocols, conducting active daily temperature checks and undertaking regular and thorough disinfecting of surfaces and tools. However, there can be no assurances that these measures will prevent a future outbreak of COVID-19 within our workforce.

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 the flight have occurred and will likely occur in the

Depending on the circumstances and market conditions, launch insurance may be extremely expensive, and we cannot assure that we will be able to acquire it on favorable terms, or at all. While we are not procuring launch insurance at this time, we are compliant with third party on orbit liability insurance requirements as required by certain countries where certain of our customers domicile.

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. Although the U.S. government may pay claims for third-party damages to the extent they exceed our insurance coverage, this depends on a government appropriation and is subject to a statutory limit. 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 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.

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.

We may experience other problems with our satellites that may reduce their performance. During any period of time in which a satellite is not fully operational, we may lose most or all of the revenue that otherwise would have been derived from that satellite. Our inability to repair or replace a defective satellite or correct any other technical problem in a timely manner could result in a significant loss of revenue. If a satellite experiences a significant anomaly such that it becomes impaired or is no longer functional, it would significantly impact our business, prospects and profitability.

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.

Space weather, including coronal mass ejections and solar flares have the potential to impact the performance and controllability of launch vehicles and spacecraft on orbit, including completely disabling our launch vehicles or spacecraft on orbit. 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.

Recent years have seen increases in the number of satellites deployed to low earthlow-earth orbits, and publicly announced plans call for many thousands of additional satellite deployments over the next decade. The proliferation of these low Earthlow-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.

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

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.

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 disproportion 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.

Our secured loan facility restricts our ability to, among other things:

In each case, subject to certain exceptions. Any failure to comply with the restrictions of our secured loan facility or any other subsequent financing agreements may result in an event of default. An event of default under the secured loan facility will allow the lender to accelerate amounts outstanding under the facility. In addition, the lender may terminate any commitments it had made to supply us with further funds. Furthermore, if we were unable to repay the amounts due and payable under the facility, the lender could proceed against the collateral securing such indebtedness, which includes all of our assets, including all of our intellectual property. As of March 31, 2021, we had fully borrowed the $25 million available under the facility. This loan comeswas originally due on March 1, 2022,2022; however, as a subsequent event, Momentus exercised its option to amortize the repayment of the loan over 24 months. See Note 15 in the consolidated financial statements within this Annual Report on Form 10-K.

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

Our reliance on suppliers to secure these raw materials and supplied components exposes us to volatility in the prices and availability of these materials. 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 which may be imposed by our Security Director and/or pursuant to the NSA. 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 growth strategy depends in part on developing reusable vehicles that will allow a single vehicle to deliver cargo multiple times to multiple orbits. These reusable vehicles will have a limited useful life, which is driven by the number of payload delivered to custom orbits and the ability to refuel in space. While we intend to design our reusable vehicles for a certain lifespan, which corresponds to a number of cycles, there can be no assurance as to the actual operational life of a vehicle or that the operational life of individual components will be consistent with its design life. A number of factors will impact the useful lives of our 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 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.

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 Astra, Firefly and Rocket Lab. In addition, several other companies are developing small launch vehicles,Lab, as well as orbital transfer and several are developing transfer vehicles,service vehicle providers such as D-Orbit, Exolaunch, Exotrail, Impulse Space, Launcher, Quantum Space, and Spaceflight Industries, MOOG, Astroscale, Astra and D-Orbit.

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, 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.

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.

We currentlyAs of December 31, 2022 we have onefour issued patent, 10 pendingseven patent family applications stages across U.S. utility patent applications, one pending, European, patent application, and four pending Patent Cooperation Treaty (“PCT”) applications.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 has, 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 issue. 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 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

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 timetime-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.

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.

WhenIf 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 whenimposedif 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.

the Security Director required to be appointed under the NSA reports any actual or potential violation of the NSA to the CFIUS Monitoring Agencies and the third-party monitor within 24 hours of discovery, and if we are found to be in violation of certain requirements in the NSA, we could be subject to liquidated damages in the amount of $100,000 per day, up to an aggregate amount of $1,000,000 per breach.

In addition, due to the restrictions under the NSA related to the protection of protected technology, systems and facilities, we could be restricted from pursuing acquisitions, customer engagements, commercial relationships or other transactions with non-U.S. persons that we believe would be advantageous to us and our stockholders.

The NSA requires that the board of directors of Momentus include a director who is approved by the CFIUS Monitoring Agencies. This director, referred to as the Security Director in the NSA, has a fiduciary duty, under the NSA to the U.S. government, to the extent consistent with his or her fiduciary duty to the Company and its stockholders under Delaware law. To the extent that the Security Director believes that a conflict of interest is reasonably likely to exist between her or his fiduciary duties under Delaware law to the Company and/or its stockholders and to CFIUS, the Security Director is required to promptly inform the CFIUS Monitoring Agencies of such conflict. In the event of such conflict, the CFIUS Monitoring Agencies could seek to institute measures to resolve such conflict which may have a material adverse effect on our business, financial condition and results of operations. Examples of situations where such conflicts could arise include, without limitation, the following:

The NSA does not impose any fiduciary duties on any other directors of the Company other than the Security Director. However, if the Security Director recommends that a director be removed from the board of directors due to an identified national security concern, as determined by the Security Director in consultation with the CFIUS Monitoring Agencies, the board of directors must ask for the resignation of such director. If such director does not

Consistent with the NSA, the Company has established a Security Committee comprised solely of the Security Director, which shall have the following powers, among others:

In addition, the Security Director is a member of the Nominating and Corporate Governance Committee. Any individual nominated by the board of directors to serve as a director of the Company will require at least a majority approval of the Nominating and Corporate Governance Committee, which majority must include the Security Director. Thus, no person could be nominated to serve as a director without the approval of the Security Director.

In addition to the powers above, the Security Director has the following responsibilities:

Our second amended and restated charter provides that the Security Director may only be removed for cause and with the approval of the CFIUS Monitoring Agencies and at least two-thirds of the voting power of the then outstanding shares of capital stock of the Company entitled to vote generally in the election of directors voting as a single class. Our second amended and restated charter also provides that any amendment to the charter or bylaws relating to this arrangement will also require the approval of the CFIUS Monitoring Agencies. As a result, it is possible that proposals to remove the Security Director for cause or to amend the provisions in our charter or our amended and restated bylaws relating to the Security Director, could be approved by the requisite stockholder vote in future stockholder meetings, but nonetheless not be effective due to the lack of approval by the CFIUS Monitoring Agencies.

As noted, as required by the NSA, if the Security Director recommends that a director be removed from the board of directors due to an identified national security concern, as determined by the Security Director in consultation with the CFIUS Monitoring Agencies, the board of directors must ask for the resignation of such director. If such director does not resign, the board of directors must call a special meeting of stockholders, in compliance with proxy rules

In addition, there could be a risk that certain powers and authority conferred to the Security Director and the CFIUS Monitoring Agencies could be determined not to be permitted under the DGCL. To the extent any of these powers and authorities were determined not to be permitted by the DGCL, we could face uncertainty regarding the legitimacy of the Security Director and the validity of any actions taken by our board. This may make it challenging for us to engage in various transactions and effectuate actions which require due authorization by the board of directors and to conduct business generally. There could also be lawsuits and stockholder litigation challenging the powers and authority conferred to the Security Director and the CFIUS Monitoring Agencies or the legitimacy of

any actions taken by members of the board of directors, alleging that certain of these arrangements or actions are not permitted by the DGCL. To the extent determined not to be permitted by the DGCL, the powers and authority conferred to the Security Director and the CFIUS Monitoring Agencies could have a material adverse effect on our business, financial condition and results of operations.

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 FCPA, 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 could further impact our business. For example, the tightening of credit in financial markets outside of the U.S. 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.

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.

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

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 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.

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.

Competition for qualified highly skilled personnel can be strong, and we can provide no assurance that we will be successful in attracting or retaining such personnel now or in the future. Any inability to recruit, develop and retain qualified employees may result in high employee turnover and may force us to pay significantly higher wages, which may harm our profitability.

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:

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 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.

In September 2020, in connection withWe have identified and subsequently mitigated various internal control deficiencies, including the remediation of material weaknesses identified during the audit of our consolidated financial statements as of and for the years ended December 31, 2019 and December 31, 2018, we identified material weaknesses and significant deficiencies in the design and operating effectiveness of our internal control over financial reporting. The material weaknesses related to the lack of timely preparation of proper financial close and account reconciliation processes, missed accruals and improper accounting for stock issuance costs. The significant deficiencies related to inadequate evidence to properly support account balances. In July 2021, in connection with the review of our quarterly consolidated financial statements for the period ended June 30, 2021, additional significant deficiencies were identified related to the execution of effective interest rate and diluted EPS calculations. These material weaknesses and significant deficiencies, if not effectively mitigated, may not allow for us to have a timely reporting process and may result in errors reported in our reporting process.

If not remediated, material weaknesses could result in material misstatements to our annual or interim consolidated financial statements that might not be prevented or detected on a timely basis, or in delayed filing of required periodic reports. If we are unable to assert that itsour internal control over financial reporting is effective, or when required in the future, if our independent registered public accounting firm is unable to express an unqualified opinion as to the effectiveness of the internal control over financial reporting, investors may lose confidence in the accuracy and completeness of our financial reports, the market price of our Class A common stock could be adversely affected and we could become subject to litigation or investigations by Nasdaq, the SEC, or other regulatory authorities, which could require additional financial and management resources.

From time to time, we may undertake acquisitions to add new products and technologies, acquire talent, gain new sales channels or enter into new markets or sales territories. In addition to possible stockholder approval, we may need approvals and licenses from relevant government authorities for the acquisitions and to comply with any applicable laws and regulations, which could result in increased delay and costs, and may disrupt our business strategy if it fails to do so. Furthermore, acquisitions and the subsequent integration of new assets, businesses, key personnel, customers, vendors and suppliers require significant attention from our management and could result in a diversion of resources from our existing business, which in turn could have an adverse effect on our operations. Acquired assets or businesses may not generate the financial results we expect. Acquisitions could result in the use

of substantial amounts of cash, potentially dilutive issuances of equity securities, the occurrence of significant goodwill impairment charges, amortization expenses for other intangible assets and exposure to potential unknown liabilities of the acquired business. Moreover, the costs of identifying and consummating acquisitions may be significant.

To date, we have limited experience with acquisitions and the integration of acquired technology and personnel. Failure to successfully identify, complete, manage and integrate acquisitions could materially and adversely affect our business, financial condition, liquidity and results of operations and could cause our stock price to decline.

As of December 31, 2021,2022, Momentus had $38.9$78.7 million of U.S. federal and $30.9$6.5 million of state net operating loss carryforwards available to reduce future taxable income. The $38.9 million in U.S. federal operating loss carryforwards will be carried forward indefinitely for U.S. federal tax purposes. While the federal net operating losses (“NOLs”) can be carried forward indefinitely, California net operating losses begin to expire in the year ending December 31, 2038. 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. It is uncertain if and to what extent various states will conform to the newly enacted federal tax law. In addition, the federal and state net operating loss carryforwards and certain tax credits may be subject to significant limitations under Section 382 and Section 383 of the U.S. Internal Revenue Code (“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 are currently, and 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 may become involved in future litigations that may materially adversely affect us

Securities Class Actions and August 4, 2021, purported stockholdersdismiss such claims with prejudice, in exchange for payment of SRAC$8.5 million by the Company (at least $4.0 million of which is expected to be funded by insurance proceeds). Refer to Note 16.

On June 16, 2022, a complaint was filed putative class action complaints against SRAC, SRC-NI Holdings, LLC, Brian Kabot, James Norris, Momentus, and Mikhail Kokorichthe Company in the United StatesDelaware Court of Chancery (Case. No. 2022-0519) by a stockholder of the Company demanding to inspect the books and records of the Company pursuant to Section 220 of the Delaware General Corporation Law. The stockholder is seeking production of books and records relating to the management of the Company and its disclosures to potential investors in connection with the Business Combination. The matter is currently stayed pending the Company’s production of certain documents to satisfy the stockholder’s requests for inspection. The Company from time to time responds to books and records requests properly submitted pursuant to applicable Delaware law.

On June 20, 2022, a shareholder derivative action was filed by a stockholder on behalf of the Company, in the U.S. District Court for the Central District of California in cases captioned Hall v. Stable Road Acquisition Corp., et al.,(Case No. 2:21-cv-05943 (the "Hall class action")22-cv-04212), against the Company (as a nominal defendant), SRAC, and Depoy v. Stable Road Acquisition Corp., et al., No. 2:21-cv-06287 (the "Depoy class action"). The allegations incurrent and former directors of the HallCompany and Depoy class actions are substantiallySRAC. This derivative action alleges the same core allegations as the allegationsstated in the Jensen class action (collectively, referred to as the "securities class actions") and the purported class period is identical. On October 20, 2021, the securities class actions were consolidatedaction litigation. Defendants dispute the allegations and intend to file a motion to dismiss the derivative action.

On January 25, 2023, a shareholder derivative action was filed by Melissa Hanna, on behalf of Momentus, Inc., in the first filed matter. Other, similar suits may follow.

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, and Mr.Fred Kennedy, and others, were added as defendantsJohn C. Rood in the Amended Complaint.Court of Chancery of the State of Delaware, in a case captioned Shirley, et al. v. Kabot et al., 2022-1023-PAF. The Amended Complaintcomplaint 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 between October 7, 2020on or before August 9, 2021. The putative class action does not name Momentus as a defendant. Regardless, the SPAC directors and July 13, 2021. officers, together with current and former directors and officers of Momentus, have demanded indemnification and advancement from Momentus, under the terms of the merger agreement and the exhibits thereto, the Delaware corporate code, the Company’s bylaws, and their individual indemnification agreements. Momentus may be liable for the fees and costs incurred by the SPAC defendants, and has an obligation to advance such fees during the pendency of the litigation.

On February 14,June 8, 2021, former co-founders and shareholders of the Company, Mikhail Kokorich and Lev Khasis signed a National Security Agreement alongside stock repurchase agreements, whereby they agreed to divest their interests in the Company in exchange for a cash payment and other considerations. The Company has maintained that this release is effective as to various advancement and indemnification claims either individual may have against the Company. On August 16, 2022, Mr. Kokorich filed a verified complaint against Momentus filedin the Delaware Court of Chancery (Case. No. 2022-0722) seeking indemnification and advancement from Momentus. Momentus disputes the allegations and intends to file a motion to dismiss the Amended Complaint. Momentus disputes the allegations in the Amended Complaint and intends to vigorously defend the litigation.action.

These securities class actions, shareholder derivative actions and other suchcurrent or 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. 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 litigationWhile a certain amount of insurance coverage is inherently unpredictable, further compounded by various claimsavailable for indemnity which mayexpenses or losses associated with current or future lawsuits, this coverage may not be fully insured,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 andor financial condition.

Most of the members of Momentus’ management team have limited experience managing a publicly traded company, interacting with public company investors, and complying with the increasingly complex laws pertaining to public companies. Additionally, several members of Momentus’ management team were recently hired, its Chief Executive Officer John Rood, Chief Legal Officer, Paul Ney, and its Chief Financial Officer, Jikun Kim. Momentus’ management team may not successfully or efficiently manage their new roles and responsibilities and may not be fully integrated as a team due to their short tenure with the company. In addition, Momentus’ transition to being a public company subjects it to significant regulatory oversight and reporting obligations under the federal securities laws and the continuous scrutiny of securities analysts and investors. These new obligations and constituents, together with obligations under the NSA, will require significant attention from Momentus’ senior management and could divert their attention away from the day-to-day management of Momentus’ business, which could adversely affect Momentus’ business, financial condition, and operating results.

In addition to the current space economy, we anticipate there could be additional “moonshot” market opportunities, including those relating to in-space data processing and in-space mining. There are considerable scientific, technological, financial, commercial, and other risks, challenges, costs and requirements of successfully executing on any business plan associated with any “moonshot” opportunities, and there is no assurance we will ever be able to realize any of the benefits from pursuing any such opportunities. Such pursuits could have the detrimental effect of diverting our management’s time and attention and our resources from our core business operations and have a material adverse effect on our business, financial condition and operating results.

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, such as the current business disruption and related financial impact resulting from the global COVID-19 health crisis.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.

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 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.

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 DoD and NASA.

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. For example, the FCC has an open notice of proposed rulemaking relating to mitigation of orbital debris, which could affect us and our operations. Application of these laws 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.

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 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.

Current U.S. government policy enables the U.S. government’s use of commercial data and space infrastructure / 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.

While we may derive limited revenue from an existing contract with NASA, we may enter into additional contracts with the U.S. government in the future, and this subjects a larger part of 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

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:

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.

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 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, including the European e-Privacy Regulation, which is currently in draft form. 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

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.

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.

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

The Company entered into an ATM program, and the Company from time to decline.time may sell up to $50.0 million of shares of Class A common stock pursuant to such program. See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations for more information. Sales of a substantial number of shares of our Class A common stock in the public markets could depress the market price of our Class A common stock and impair our ability to raise capital through the sale of additional equity securities. We cannot predict the effect that future sales of our Class A common stock would have on 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.

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. As of the Business Combination, on August 12, 2021, there were approximately 79,772,262 shares of Class A common stock outstanding, and Momentus stockholders, the Sponsor, its affiliate SRAC Partners and the PIPE Investors collectively owned approximately 19.50% of the outstanding shares of Class A common stock, of which approximately 6.97% of the outstanding shares of Class A common stock was held by the Sponsor and its affiliate SRAC Partners.

Following the expiration of such lock-ups, Sponsor will not be restricted from selling the shares of Class A common stock that it beneficially owns, other than by applicable securities laws. Additionally, neither certain Momentus stockholders nor the PIPE Investors are restricted from selling any of their shares of Class A common stock, other

The Sponsor and certain holders of Class A common stock (including SRAC Partners and Prime Movers Lab Fund I, L.P and its affiliates), in each case who received Class A common stock pursuant to the Merger Agreement and the transactions contemplated thereby entered into the Amended and Restated Registration Rights Agreement (the “Registration Rights Agreement”) in respect of the shares of Class A common stock issued to Sponsor and such stockholders in connection with the transactions set forth above. Pursuant to the Registration Rights Agreement, such holders and their permitted transferees are entitled to certain customary registration rights, including, among other things, demand, shelf and piggy-back rights, subject to cut-back provisions. Pursuant to the Registration Rights Agreement, the Sponsor and SRAC Partners have agreed not to sell, transfer, pledge or otherwise dispose of shares of Class A common stock or other securities exercisable therefor for certain time periods specified therein.

We have no current plans to pay cash dividends on our Class A common stock. The declaration, amount and payment of any future dividends will be at the sole discretion of the board of directors. The board of directors may take into account general and economic conditions, our financial condition and operating results, our available cash, current and anticipated cash needs, capital requirements, contractual, legal, tax and regulatory restrictions, implications on the payment of dividends by us to our stockholders and such other factors as the board of directors may deem relevant.

In addition, the terms of any future indebtedness would likely contain a number of restrictive covenants that impose significant operating and financial restrictions on us, including restricting or limiting our ability to pay cash dividends. Accordingly, we may not pay any dividends on our Class A common stock in the foreseeable future.

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. Securities and industryOnly three securities analysts do not currently, and may never,have published research on our stock in the last 12 months. If some or all of these analysts cease to publish research on us. If securities and industryour stock or if additional analysts do not commence coverage, of us,then our stock price and trading volume would likelycould 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.

Certain provisions of our second amended and restated charter, as well as our amended and restated bylaws 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:

In addition, we have not opted out of the provisions of Section 203 of 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 bylaws 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 charter 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:

This provision would not apply to suits brought to enforce a duty or liability created by the Securities Act or the Exchange Act or any claim for which the U.S. federal courts have exclusive jurisdiction. Our second amended and restated charter further provides that, unless we consent in writing to the selection of an alternative forum, to the fullest extent permitted by law, the federal district courts of the United States of America will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act or the rules and regulations promulgated thereunder.

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.

Momentus relies on its employees in the day to dayday-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.

In addition, Momentus has experienced shortages of qualified labor in the past and may experience them in the future. Any shortages of qualified labor may have a material adverse effect on Momentus’ business, prospects, financial condition and operating results.

We prepare our consolidated financial statements in accordance with GAAP. These accounting principles require us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of our consolidated financial statements. We are also required to make certain judgments that affect the reported amounts of revenues and expenses during each reporting period. We periodically evaluate our estimates and assumptions including, but not limited to, those relating to business acquisitions, revenue recognition, restructuring costs, recoverability of assets including customer receivables, contingencies, stock-based compensation and income taxes. We base our estimates on historical experience and various assumptions that we believe to be reasonable based on specific circumstances. These assumptions and estimates involve the exercise of judgment and discretion, which may evolve over time in light of operational experience, regulatory direction, developments in accounting principles and other factors. Actual results could differ from these estimates as a result of changes in circumstances, assumptions, policies or developments in the business, which could materially affect our consolidated financial statements.

Momentus leases its office space, which consists of a primary facility located in 3901 North First St., San Jose, CA 95134, and smaller facilities in Santa Clara, CA.95134. Our primary facility lease expires in February 2028. We believe our current office space is sufficient to meet itsour needs until the expiration of this lease. These leases are utilized by Momentus’ single reporting segment.

From time to time, we may be subject to various claims, lawsuits, and other legal and administrative proceedings that may arise in the ordinary course of business. Some of these claims, lawsuits, and other proceedings may range in complexity and result in substantial uncertainty; it is possible that they may result in damages, fines, penalties, non-monetary sanctions, or relief. However, we do not consider any such claims, lawsuits, or proceedings currently pending, individually or in the aggregate, to be material to our business or likely to result in a material adverse effect on our future operating results, financial condition, or cash flows.

On August 13, 2021, the Company's common stock and public warrants began trading on the Nasdaq Global Market (“the Nasdaq”(the “Nasdaq”). Our Class A common stock is traded on the Nasdaq under the symbol "MNTS", and public warrants to purchase our common stock are traded on the Nasdaq under the symbol "MNTSW".

As of February 1, 2022,28, 2023, there were 11139 holders of record of our shares of common stock. The actual number of stockholders of our common stock is greater than this number of record holders and includes stockholders who are beneficial owners but whose shares of common stock are held in street name by banks, brokers and other nominees.

We have no current plans to pay cash dividends on our common stock.

There were no issuer purchases of equity securities of the Company during the three months ended December 31, 2021.2022.

During the year ended December 31, 2021,2022, we issued 52,503246,855 shares of common stock as compensation to a former employeesemployee of Momentus Space, LLC. The issuances of such shares were exempt from registration pursuant to Section 4(2) of the Securities Act of 1933, as amended (the “Securities Act”) or the rules and regulations promulgated there under, including Rule 701.

On May 25, 2022, the Company launched Vigoride 3 to low-earth orbit aboard the SpaceX Transporter-5 mission. In addition to Vigoride 3, Momentus used a second port on the same SpaceX mission to fly a third-party deployer from a partner company. On May 25, 2022, Momentus used the third-party deployer to place its first customer satellite in orbit.

On May 26, 2022, upon establishing two-way contact between Vigoride 3 in low-earth orbit and a ground station on Earth, Momentus discovered that Vigoride 3 had experienced certain anomalies after its launch, primarily relating to its deployable solar arrays, which provide power to the spacecraft and its subsystems. The Company quickly worked to address the anomalies, identify root causes and pursue solutions to be implemented in advance of future missions.

The Company determined that Vigoride 3’s deployable solar arrays, which are produced by a third party, and are folded and stowed during launch, did not operate as intended once in orbit. This resulted in low power and communications issues with customersthe spacecraft. Meanwhile, the spacecraft's fixed, body-mounted solar panels appeared to have worked as intended and were able to provide some power to the spacecraft. The Company and the producer of the solar arrays identified a mechanical issue as the root cause of the deployable arrays not operating as intended. The Company also identified the root cause of the anomalies that it experienced with other spacecraft systems during the low-power state.

We anticipate there could bepotential 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 LEOlow-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 LEOlow-earth orbit are also 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 Hosted Payload,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 technology in space. Satellite constellations have relatively lowshort lifespans and, in our view, will require maintenance, de-orbiting, and other general servicing with higher frequency.

When our technology is fully developed and validated in the future, we currently plan to provide the following infrastructure services to the space economy:

We are designing our water plasma thrusters to enable our vehicle to efficiently transport each customer payload to its respective orbit. We believe our hub-and-spoke model 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.

Initially, our vehicles will de-orbit after delivering our customer payloads to their final orbits, our vehicles will de-orbit. However,orbits. Ultimately, our plan is to develop the capability for our vehicles to be reusable, such that, upon delivery of the payload, they will be capable of remaining in space to conduct additional missions.

Payload model, our vehicle, after transporting a customer payload to a specific orbit our vehicle would stay connected to the payload for the duration of its mission to provide continuous power, orbit maintenance, orientation, and communications to support telemetry, commanding, and downlinking of payload data. Our objective is to offer a higher degree of modularity which we believe has the potential to significantly increase orbital accessibility and/or lower manufacturing costs for a wide range of satellite operators.

Our primary research and development objectives focus on the development of our existing and future in-space transfer and service vehicles and related water plasma propulsion technology.

Ahead of our first Vigoride launch, weWe have received significant interest from a range of satellite operators, satellite manufacturers, satellite aggregators, launch service providers, and others. While we have not recognized any revenue from completed commercial launches throughAs of December 31, 2021,2022, we had collected approximately $1.6$2.7 million in customer deposits related to future launches. While our standard contracts do not contain refunds or recourse provisions that enable our customers to recover any non-refundable deposits that have been paid, we issued refunds totaling $1.4 million to customers induring the twelve months endingyear ended December 31, 2021 due to cancelled launches for 2021 in order to foster future business relationships and customer goodwill. There were no refunds paid during the year ended December 31, 2022.

Because our technologies have not yet been fully tested, our service offering to our customers on our inaugural missiondemonstration missions will be limited. To reflect this, we expect to provide discounts to customers on this missionthese demonstration missions relative to the price we intend to eventually charge for our transportation services. During our inaugural mission,demonstration missions, we plan to demonstrate Vigoride’s ability to deploy satellites at the point at which it is dropped off by the launch vehicle, rather than independently maneuver customer satellites to custom orbits.satellites. Once all customer payloads have been released, we plan to perform certain maneuvers and technology demonstrations to validate our technology and establish the potential commercial viability of our strategy. This approach limits risk for us as well as for our customers.

We have signed contracts for approximately $67$33 million in backlog (potential revenue), as of January 31, 2022.February 28, 2023. These agreements containinclude firm orders as well as options, allowingwhich allow customers to opt-in to launches on shorter notice without requiring a separate agreement. The breadth of these signed contracts spans across 2418 companies in 1512 countries. 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.

The top ten customers in our backlog represent approximately 98% of the customers for convenience, that were not refundable.total dollar value of our backlog.

In addition, backlog is typically subject to large variations from quarter to quarter and comparisons of backlog from period to period are not necessarily indicative of future revenues. Furthermore, some contracts comprising the backlog are for services scheduled many years in the future, and the economic viability of customers with whom we have contracted is not guaranteed over time. As a result, the contracts comprising our backlog may not result in actual revenue in any particular period, or at all, and the actual revenue from such contracts may differ from our backlog estimates. The timing of receipt of revenues, if any, on projects included in the backlog could change because many factors affect the scheduling of missions and adjustments to contracts may also occur. The failure to realize some portion of our backlog could adversely affect our revenues and gross margins.

On August 12, 2021, the Company consummated a merger pursuant to certain 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 (the “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 is accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, SRAC is treated as the “acquired” company for financial reporting purposes. We are deemed the accounting predecessor of the combined business, and Momentus Inc., as the parent company of the combined business, is the successor SEC registrant, meaning that our consolidated financial statements for previous periods are disclosed in the registrant’s future periodic reports filed with the SEC.

In addition, the lender will havehas certain rights to participate in future private equity offerings (including convertible notes or bridge financings) of Momentus.

On July 13, 2021, the Company agreed to a settlement with the SEC on a “neither admit nor deny” basis, in anticipation of cease-and-desist proceedings relating to certain violations of antifraud provisions of the federal securities laws alleged by the SEC. As a result of the settlement, the Company agreed to a civil penalty of $7.0 million, $2.0 million of which was paid immediately and $5.0 million of which is payable within one year of the settlement order, and outstanding as of December 31, 2021.was paid on July 8, 2022.

As a result of the Business Combination, which generated $247.3 million of gross proceeds (as described in Note 3), the Company paid the Co-Founders $40.0 million in addition to the initial consideration paid of $3. The Company recorded the consideration paid as a reduction of common stock and additional paid in capital. Pursuant to the NSA, a portion of those divestment proceeds were placed in escrow accounts, and may not be released to the divested investors until after completion of audit by a third partythird-party auditor of the investors compliance with the NSA and the lapse of a 15 day period without an objection from the CFIUS Monitoring Agencies. Following the third-party audit of the investors’ NSA compliance, all of the escrowed divestment proceeds were released to the Co-Founders as of March 1, 2022 in accordance with the NSA.

If the Company were to undertake a business combination or capital raising transaction or series of transactions (whether in the form of debt or equity) resulting in cash proceeds of approximately $2.7 million or more, the Company would need to pay an aggregate of $10.0 million to the Co-Founders in accordance with the terms of the stock repurchase agreements (see Note 11). As a subsequent event, the remaining proceeds were released from escrow to the divested investors, see Note 15 in the accompanying consolidated financial statements. The NSA also establishes various requirements and restrictions on February 27, 2023 the Company in orderraised $10.0 million through the sale of securities, which triggered the liability under the stock repurchase agreements. Refer to protect national security, certain of which may materially and adversely affect our operating results due to uncertainty associated with and the cost of compliance with security measures, and limitations on our control over certain U.S. facilities, contracts, personnel, vendor selection and operations.Note 16.

Both Messrs. Kokorich and Khasis have,

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 Momentus in the Delaware Court of Chancery (Case. No. 2022-0722) seeking indemnification and advancement from Momentus. On October 14, 2022, Momentus filed its motion to dismiss this action. Momentus disputes with both Messrs.

See Note 14.

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. From inception to December 31, 2021, we have not yet completed a commercial launch of customer cargo. However, as of December 31, 2021 we have signed contracts with customers and have collected approximately $1.6 million in customer deposits, which are recorded as non-current contract liabilities in our consolidated balance sheets, and are related to performance obligations not expected to be completed for at least one year.

fees that have been paid) upon the earlier of the satisfaction of our performance obligation or when the customer cancels the contract.

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. As a result of the Company’s inability to complete any launches in 2021 (refer to Note 4 for additional information), the Company issued customer refunds of $1.4 million to customers during the year ended December 31, 2021. There were no refunds during the year ended December 31, 2022.

Cost of revenue consists primarily of expenses associated with the cost of the orbital transferservice vehicle and third-party launch costs. Until the orbital transferservice vehicle design is completed and released for production, the cost of these orbital transferservice vehicles is being expensed as research and development costs as materials and services are received. The current design and technology allow for a single use of the orbital transferservice vehicle.

Research and development expenditures consist primarily of the cost for the following activities for developing existing and future technologies for our 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, material, 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, 2021,2022, we have expensed all research and development costs associated with developing and building our vehicles. Once we have achieved technological feasibility and released the design for volume

production, we will capitalize the costs to construct any additional components for the vehicles. We expect to continue to see an increase in our research and development expenses as we develop our next generation of vehicles.

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. As we continue to grow as a company, we expect that our selling, general and administrative costs will increase on an absolute dollar basis. The Company also recorded one-time launch costs related to the validation of the business model as selling, general and administrative costs.

We also have begun to 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 as well as to comply with the NSA.

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

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

Other income/expense primarily relates to the change in the estimated fair value of our SAFE notes and warrants, and non-recurring fees incurred in conjunction with the SAFE and Term Loan financing, SEC settlement cost, and the Business Combination.

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.

Specifically, our operating expenses will increasecontinue as we:

We expect that our current cash and cash equivalents, and our projected gross profit (revenue less cost of revenue), and additional funding from equity or debt financings will enable us to fund anticipated operating expenses, research and development expenses and capital expenditures overbeyond the next 12 months. Additionally, we believe that the payments in the form of non-refundable deposits we receive from our customers prior to launch will provide sufficient funding and liquidity to support costs incurred related to that mission.

We enter into short-term contracts for ‘last-mile’ satellite and cargo delivery, payload hosting and in-orbit servicing options with customers that are primarily in the aerospace industry. From inception to December 31, 2021, we have not completed a commercial launch of customer cargo and as a result, have not recognized revenue related to performance obligations to date. However, as of December 31, 2021 we have signed contracts with customers and have collected approximately $1.6 million in customer deposits, which are recorded as non-current contract liabilities in our consolidated balance sheet and will be recognized asWe recognize revenue (along with any other fessfees that have been paid) at a point in time, upon the earliersatisfaction of the satisfaction of ourCompany’s performance obligation. For transportation services, the performance obligation oris satisfied when the customer cancels the contract.is delivered to their designated orbit.

Our launch services are considered a single performance obligation, to transport the customers’ payload to a specified orbit in space. We recognize revenue 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.

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 606-10-50-8(b).

During the third quarter of 2022, the Company resolved the variable consideration uncertainties that had caused it to defer revenue and cost of revenue from its inaugural launch. As a result, the Company amortized the deferred $14 thousand to cost of revenue.

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.

We are 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.
