Insights

Nauticus adds a high-yield, convertible preferred layer to its capital structure.

Nauticus Robotics has implemented its earlier financing agreement by creating Series D Convertible Preferred Stock. The authorization of up to 50,000 shares at a stated value of $1,000 each and 10% cumulative dividends adds a senior security ahead of common equity.

The preferred shares can convert into common stock, subject to Nasdaq stockholder approval requirements, and include liquidation, redemption and voting rights. These features mean the Series D sits between debt and common equity in risk and priority, influencing both future cash obligations and potential dilution paths.

Economic impact will depend on how much of the authorized Series D is ultimately issued, the timing of any conversions into common stock, and how redemption and voting rights interact with future corporate actions under the Purchase Agreement dated February 6, 2026.

Series D Convertible Preferred Stock financial
"establishing a new series of preferred stock designated as the Company's Series D Convertible Preferred Stock"
Series D convertible preferred stock is a class of shares issued in a later-stage funding round that gives holders priority over common shareholders for payouts and often a fixed dividend, while including an option to convert those shares into common stock. It matters to investors because it affects who gets paid first if a company is sold or liquidates and can change ownership stakes and voting power when converted, similar to holding a safer ticket that can be exchanged for regular tickets later.
Certificate of Designation regulatory
"the Company filed ... a Certificate of Designations of Series D Convertible Preferred Stock"
A certificate of designation is a formal document that spells out the specific rights and rules attached to a particular class or series of stock, usually preferred shares. Think of it as a rulebook or menu that lists dividend terms, liquidation priority, conversion or redemption rights and any special voting protections; investors use it to judge how much income, control or downside protection those shares will provide compared with other securities.
cumulative dividends financial
"cumulative dividends at a rate of 10% per annum"
A feature of some dividend-paying securities—most often preferred shares—where any dividends the issuer skips or defers are recorded and must be paid later before other shareholders receive dividends. Think of it like missed subscription payments that pile up and must be settled first. For investors this matters because it increases the likelihood of receiving owed income and gives these holders priority on company cash, affecting income reliability and risk.
liquidation preferences financial
"including, among other things •a stated value ... •cumulative dividends ... •conversion rights ... •liquidation preferences; and •redemption and voting rights"
Liquidation preferences are contract terms that determine who gets paid first and how much when a company is sold, merged, or shuts down. Think of them like a special checkout lane that lets certain investors reclaim a set amount—often their original investment or a multiple—before other owners receive any proceeds; this protection changes how much different stakeholders can expect to get from an exit and influences investment value and negotiating power.
redemption and voting rights financial
"•liquidation preferences; and •redemption and voting rights"
Nasdaq stockholder approval requirements regulatory
"conversion rights into shares ... subject to the terms and limitations set forth therein, including applicable Nasdaq stockholder approval requirements"
