Other than as set forth below, there have been no material changes from the risk factors previously disclosed in Part I, Item 1A of our Annual Report on Form 10-K, as filed with the SEC on February 26, 2026 and Part II, Item 1A of our Quarterly Report on Form 10-Q, as filed with the SEC on August 10, 2026.

Our future revenue and operating results are dependent on our ability to generate a sustainable order rate for our products and services and develop new technologies to meet the needs of our customers or potential new customers.

Our financial performance is dependent on our ability to generate a sustainable order rate for our products and services as well as our ability to monetize products still in development. This can be challenging and may fluctuate on an annual basis as the number of contracts awarded varies. If we are unable to win new awards or execute existing contracts as expected, our business, results of operations, and financial position could be further adversely affected. Furthermore, if our customers experience delays or technical challenges with their products or services or exercise delay or termination rights under new or existing contracts, our ability to recognize the full potential value of such contracts could also adversely affect our business, results of operations and financial position.

The cyclical nature of the rocket launch services, mission services, spacecraft and spacecraft component markets could negatively impact our ability to accurately forecast customer demand. The markets that we serve may not grow in the future and we may not be able to maintain adequate gross margins or profits in these markets. Our growth is dependent on the growth in the sales of services provided by our customers, our customers’ ability to anticipate market trends, and our ability to anticipate changes in the businesses of our customers and to successfully identify and enter new markets. If we fail to anticipate such changes in demand, or such demand does not materialize to the extent we expected or at all, our business, results of operations, and financial position could be adversely affected.

The rocket launch services, mission services, spacecraft and spacecraft component industries are each characterized by development of technologies to meet changing customer demand for complex and reliable products and services. Our current development projects include spacecraft capabilities; new reaction wheel sizes; and a new medium-lift rocket, called Neutron, for constellation deployment, interplanetary missions and potentially human spaceflight. Our products and services embody complex technology and may not always be compatible with current and evolving technical standards and systems developed by others. Failure or delays to meet the requisite and evolving industry or user standards could have a material adverse effect on our business, results of operations, and financial condition. Failure of suppliers to deliver against end customer requirements could lead to a material adverse effect on our financial results.

We have previously experienced, and may experience in the future, delays or other complications in the design, manufacture and commercialization of new rocket launch services, including the development and launch of our Neutron launch vehicle, mission services, spacecraft, spacecraft components and related technology. For example, we experienced a qualification testing failure of the Neutron Stage 1 tank on January 21, 2026 which ruptured the tank during a hydrostatic pressure trial resulting in an impact to Neutron’s launch schedule. In addition, during the fourth quarter of 2026, we identified a manufacturing process issue affecting first-stage composite structures that resulted in a further delay to the expected timing of Neutron’s inaugural launch. If we fail to develop and successfully commercialize new technologies, if we fail to develop such technologies before our competitors, or if such technologies fail to perform as expected, or are inferior to those of our competitors, our business, financial condition and results of operations could be materially and adversely impacted.
