The U.S. government can terminate contracts at its convenience.

Manufacturing and Suppliers

As part of the original development of engineering prototypes, Nauticus Robotics has established supplier relationships with key commercial-off-the-shelf (“COTS”) and custom part manufacturers. Consideration is given within the Company's international supply chain for redundancy, where possible. In cases of limited supplier options, Nauticus Robotics initiates procurement early in the manufacturing schedule to mitigate risk of supply interruption.

Currently, Nauticus Robotics manages a supply chain with many suppliers that specialize in parts aimed toward subsea vehicles. A key component of the Aquanaut subsea vehicle is the energy storage system — a Li-ion battery. There are a variety of suppliers available to provide this battery subsystem. One battery that Nauticus Robotics uses is from SubCTech, a German company. The batteries are a long-lead-time item and are ordered well in advance of the time they are required to be integrated into the vehicle.

Nauticus Robotics is committed to exploring the options that will lead to the most capital-efficient manufacturing process and support its sales-driven build schedule.

In the fourth quarter of 2025, Nauticus entered into a Manufacturing and Sales Agreement with Forum Energy Technologies ("FET") for the Olympic Arm all electric manipulators. Under the agreement, FET will lead the commercialization, manufacturing, and distribution of the Olympic Arm electric manipulator system, while Nauticus continues to advance on the next generation manipulator as well as the robotics, autonomy, and intelligent control technologies.

In the first quarter of 2026 Master Investment Group agreed to provide an initial $3 million investment tranche for Nauticus' UAE business unit startup activities, with additional capital up to $47 million for Nauticus to form a dedicated manufacturing, sales, and offshore services business unit in the UAE. Initial facility sites are already under evaluation.

Master Investment Group is expected to fund facility development, workforce localization, and initial manufacturing capability, positioning the operation as a regional center for advanced subsea robotics.

As a consequence of Nauticus use of third party suppliers for a substantial portion of its product manufacturing process, the direct purchase of raw materials is not material to its operations.

Government Regulation

The Company's business is heavily regulated and is consequently subject to numerous laws and regulations that govern operations, including but not limited to the Federal Acquisition Regulation (FAR), the Defense Federal Acquisition Regulation Supplement (DFARS), the Truth in Negotiations Act (TINA), the Cost Accounting Standards (CAS), the International Traffic in Arms Regulations (ITAR), and the Export Administration Regulations (EAR). Compliance with these regulations is critical to its ability to compete for and perform contracts with the U.S. Government. Specific maritime related laws and regulations include the Jones Act, Ports and Waterways Safety Act, International Convention for the Safety of Life at Sea (SOLAS), Clean Water Act (CWA), Oil Pollution Act of 1990 (OPA 90), Seaman’s Protection Act, Foreign Corrupt Practices Act (FCPA), and the Defense Production Act (DPA). This is an example of applicable regulations but does not include all.

Intellectual Property

The ability to obtain and maintain intellectual property protection through patent and trademark filings is important to the Company's business. Nauticus utilizes a combination of the protections afforded to the owners of patents, copyrights, trade secrets, and trademarks to secure its intellectual property. In addition, Nauticus requires employment agreements which stipulate IP protections for the company. For external relationships, non-disclosure agreements and other contractual restrictions are used to establish and protect intellectual property.

Nauticus will file for patent protection if the invention is believed to be patentable and the resulting patent will be beneficial in protecting the invention in the marketplaces. Consideration is also given, particularly with respect to software, as to the benefits of seeking a patent against the associated market risks of providing public exposure of the invention. In many cases with its software, Nauticus holds this code and algorithms as trade secrets.

Nauticus has patented its re-configurable hull design for subsea vehicles. This approach protects the Company’s vehicle configuration that enables it to transit long distances and then transform into a working robot once at the worksite. This capability is key to exploiting the vehicle architecture and its tetherless operational modes. Similarly, Nauticus also obtained patent protection for its all-electric, work class electric robotic manipulators. These manipulators are the first in their market class and utilize specialized actuation systems to achieve the strength performance necessary for work class systems.

Nauticus has also filed for protection of its Company name and brand under trademark registration in the United States.

Employees and Human Capital Resources

The Company's workforce plays a critical role in driving its business forward. We had 51 employees as of December 31, 2025. None of its employees are covered by collective bargaining agreements, and the Company has not experienced any strikes or work stoppages related to labor relations issues. Nauticus' human capital strategies focus on identifying, recruiting, retaining, rewarding, and integrating both its existing and new employees. The Company endeavors to recruit the most qualified individuals for each position regardless of gender, ethnicity or other protected characteristics. It is Nauticus policy to fully comply with all laws applicable to discrimination in the workplace. It has successfully navigated a workforce transformation, aligning our organization to prioritize the support and advancement of existing products while balancing ongoing innovation efforts beyond early-stage research and prototyping.

Seasonality

Offshore ROV and AUV operations are subject to seasonal variation, and Gulf Coast operations are generally more active from April through October each year. In Brazil, operations are generally more active from November through March.

Nauticus operations are currently concentrated in the US offshore market. To address the seasonality of the business, Nauticus may pursue a strategy of rotating operating assets between the Gulf Coast and other international locations.
