HORNBECK OFFSHORE SERVICES, INC. (HLX) reported that investment manager Whitebox Advisors LLC and Whitebox General Partner LLC, each a ten percent owner, have filed an initial statement of beneficial ownership. The report shows indirect holdings through certain private investment funds in both common stock and Jones Act Warrants.

The private funds hold Jones Act Warrants that are immediately exercisable for up to 29,634,393 shares of Common Stock in total, without giving effect to a Beneficial Ownership Limitation tied to U.S. citizenship requirements. Separately, the private funds also indirectly hold 8,239,303 shares of Common Stock.

The filing notes that the Jones Act Warrants have no expiration date and carry a nominal exercise price of $0.00001 per share. Exercise of these warrants is constrained for non‑U.S. citizens by a 4.9% Beneficial Ownership Limitation based on the issuer’s common shares outstanding, and each reporting person disclaims beneficial ownership beyond its pecuniary interest.

The filing also notes an attached Exhibit 24 granting a Power of Attorney, authorizing another party to sign SEC documents on Rosen’s behalf for administrative convenience.

HORNBECK OFFSHORE SERVICES, INC. (HLX) has a new Form 3 from ASOF HOS GP, LLC and affiliated funds, reporting their status as ten percent owners through indirect holdings of common stock and warrants. The warrants are immediately exercisable into common stock at an exercise price of $0.00001, do not expire, and are subject to citizenship and transfer limitations. Complex Ares-affiliated structures hold these positions, with multiple entities disclaiming beneficial ownership of certain managed accounts.

HORNBECK OFFSHORE SERVICES, INC. (HLX) has a new Form 3 filed by several Ares-affiliated investment entities as ten percent owners, reporting only initial indirect holdings and no new trades.

The reporting entities indirectly hold warrants exercisable for 5,031,943 and 37,897,551 shares of Common Stock, with an exercise price of $0.00001 per share. The warrants are immediately exercisable, do not expire, and are subject to citizenship rules and limitations on exercise, sale, transfer or other disposition. Beneficial ownership of certain managed-account shares is expressly disclaimed.

HORNBECK OFFSHORE SERVICES, INC. (HLX) received an initial ownership report on Form 3 from Ares Management LLC and affiliated entities, stating that various Ares-managed funds and accounts may be deemed to share beneficial ownership of indirect holdings of Hornbeck common stock and associated warrants. The reported positions include warrants on common stock that are immediately exercisable at an exercise price of $0.00001 per share and, according to the disclosure, do not expire, but are subject to citizenship rules and limitations on exercise, sale, transfer or other disposition. The Ares entities and certain individuals emphasize that they disclaim beneficial ownership of securities not held of record by them, including specified managed-account shares.

Hornbeck Offshore Services, Inc. (HLX) discloses that a group of Ares-affiliated investment entities reports beneficial ownership of up to 61,738,413 shares of common stock, representing 23.7% of the class, including shares issuable upon exercise of certain warrants.

The stake arose from the September 1, 2026 closing of a merger in which Helix Energy Solutions Group converted into a Delaware corporation and combined with Legacy Hornbeck, then changed its name to Hornbeck Offshore Services, Inc. Ares funds and accounts received 27,425,863 shares of common stock and hold Jones Act Warrants exercisable for an additional 42,929,494 shares. The Ares investor has board-designation rights for up to two directors while its group beneficially owns at least 20% of the common stock, subject to Jones Act and exchange requirements, and these rights step down to one director while ownership remains at least 10%.

A standstill and transfer-restriction framework limits the Ares group from exceeding 30% ownership (subject to specified exceptions), pursuing certain control transactions or proxy contests during a defined standstill period, and imposes a 180‑day lock-up on most transfers after closing. A registration rights agreement requires Hornbeck to use reasonable best efforts to file a shelf registration statement covering the Ares holders’ registrable securities and provides customary underwritten and piggyback registration rights, including for shares underlying the Jones Act Warrants.

HORNBECK OFFSHORE SERVICES, INC. (HLX) has a significant shareholder group led by Whitebox Advisors LLC and Whitebox General Partner LLC, which each report beneficial ownership of 37,873,696 shares of common stock, representing 15.0% of the class, including shares underlying Jones Act-related warrants subject to a Beneficial Ownership Limitation.

Whitebox Multi-Strategy Partners, LP reports beneficial ownership of 19,491,691 shares, or 8.2% of the common stock, also including shares underlying Jones Act Warrants. The ownership calculations are based on 222,293,745 shares outstanding as of September 9, 2026, with warrant exercises constrained so non-U.S. holders do not exceed 4.9% ownership.
