On December 1, 2023, Helix Energy Solutions Group, Inc. issued $300 million aggregate principal amount of 9.750% Senior Notes due 2029 under an indenture, dated as of December 1, 2023, among the Company, as issuer, the guarantors listed therein and The Bank of New York Mellon Trust Company, N.A., as trustee. The Notes have not been and will not be registered under the Securities Act of 1933, as amended or any state securities laws and, unless so registered, may not be offered or sold in the United States absent registration or an applicable exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and other applicable securities laws. The notes and related guarantees will be offered only to persons reasonably believed to be qualified institutional buyers in reliance on the exemption for registration set forth in Rule 144A of the Securities Act, and outside of the United States to non-U.S. persons in reliance on the exemption from registration set forth in Regulation S Under the Securities Act.

The Company intends to use the net proceeds from the offering, together with cash on hand and shares of common stock, as necessary, to pay the cost of extinguishing its obligations with respect to its outstanding 6.75% Convertible Senior Notes due 2026, which may include privately negotiated transactions, and payments in settlement of redemptions or conversions of such notes. The Company reserves the right to settle and extinguish the 2026 Convertible Notes in cash, shares of its common stock, or any combination thereof. The Company intends to use the remainder of the net proceeds from this offering, if any, for general corporate purposes, which may include repayment of other indebtedness.

The Notes are initially guaranteed on a senior unsecured basis by the subsidiaries of the Company that guarantee its secured credit facility, as well as certain future subsidiaries that guarantee certain of the Company?s indebtedness, including its secured credit facility. The Notes will bear interest from December 1, 2023 at an annual rate of 9.750% payable on March 1 and September 1 of each year, beginning on March 1, 2024. The Notes will mature on March 1, 2029.

At any time prior to March 1, 2026, the Company may, at its option, redeem the Notes, in whole or in part, at a redemption price equal to 100.0% of the aggregate principal amount of the Notes redeemed plus a make-whole premium and accrued and unpaid interest thereon, if any, to, but excluding, the redemption date. At any time on or after March 1, 2026, the Company may, at its option, redeem the Notes, in whole or in part, at the redemption prices set forth in the Indenture. At any time Prior to March 1, 2026, the Company may, at its option, on any one or more occasions, redeem up to 40% of the notes at a price equal to 109.750% of the aggregate principal amount of the notes plus accrued and unpaid interest, if any, to, but excluding, the redemption date, in an amount not exceeding the proceeds of certain equity offerings.

The Notes will be the Company?s general senior unsecured obligations and will rank equally in right of payment with all of its existing and future senior indebtedness that is not subordinated, including its secured credit facility. The Notes will be effectively junior to all of the Company?s existing and future secured indebtedness, including indebtedness under its secured credit facility, to the extent of the value of the assets securing such indebtedness and structurally subordinated to all existing and future liabilities of the Company?s non-Guarantor subsidiaries, including trade payables of such non-Guarantor subsidiaries.
