Norton Rose Fulbright advises Nauticus Robotics in ATM stock offering

Global law firm Norton Rose Fulbright advised Nauticus Robotics, Inc. (Nauticus) in its at-the-market (ATM) stock offering, pursuant to a shelf registration statement that originally registered securities to be offered in the aggregate amount of US$100 million. Nauticus filed a prospectus supplement that reflected the most recent increase of the ATM offering's capacity on June 30, 2025.

Nauticus develops autonomous subsea robotics and software for both the commercial and defense business sectors. The company will use the capital raised for general corporate purposes, including to develop and commercialize the Aquanaut, its flagship subsea robot that runs exclusively on electric power without tethers.

ATM offerings enable companies to strategically raise quick and targeted capital more frequently without driving down the stock price by “dribbling” the sale of common stock into the existing trading market from time to time, at the market price. An ATM requires that companies have an effective shelf registration statement in place and companies are not required to file a new registration statement each time they sell securities.

Nauticus’ ATM offering is subject to “baby shelf” rule limitations for small cap Nasdaq and NYSE companies that have less than US$75 million public float. This rule enables companies to register securities for sale up to one-third of their public float over a 12-month period.

Norton Rose Fulbright’s deal team was led by Amelia Zhang (Houston) and Brandon Byrne (Dallas) and included Sloka Srisai Valleru Borrego (Houston) and Siyi Zhu (New York).
