Nauticus Robotics Extends Debenture Maturity to Sept 9, 2027

What Happened

• On September 9, 2026, Nauticus Robotics, Inc. received a Holder Notice from ATW Special Situations II, LLC exercising its contractual right to extend the maturity date of certain Original Issue Discount Senior Secured Convertible Debentures issued under the November 4, 2024 securities purchase agreement.
• The extensions apply to the full outstanding principal of $3,985,000 and related accrued or future interest, liquidated damages and other amounts, moving the maturity date from September 9, 2026 to September 9, 2027. The extensions became effective upon delivery of the Notice and were disclosed in the Company’s Form 8-K filed September 11, 2026.

Key Details

• Holder: ATW Special Situations II, LLC (per Exhibit 10.1).
• Amount extended: $3,985,000 aggregate outstanding principal.
• New maturity date: September 9, 2027 (previously September 9, 2026).
• Terms: Interest and other amounts continue to accrue; debentures remain convertible and enforceable; no amendment fee, consent fee or additional consideration payable; existing guarantees, liens and security interests remain in place.

Why It Matters

• This action delays a near-term cash / repayment deadline by one year, reducing immediate liquidity pressure on Nauticus Robotics through Sept 2027.
• The debt remains on the company’s balance sheet, continues to accrue interest and is still convertible, so dilution risk and cash cost are unchanged under existing terms.
• Because the holder used an existing contractual extension right and no terms were renegotiated, the company did not incur extra fees nor change the substantive terms of the financing.
