Under the terms of the merger agreement, each share of Hornbeck common stock was converted into the right to receive a fixed exchange ratio of 10.27167 shares of the combined company's common stock. On a fully diluted basis, Hornbeck shareholders were expected to own approximately 55 percent of the combined company and Helix shareholders approximately 45 percent. The transaction was structured as tax-free to shareholders of both companies. No specific aggregate deal value, enterprise value, or implied equity value figure was disclosed in the filings reviewed, and no EV/EBITDA, P/E, or similar valuation multiple for the transaction itself was provided.
Structurally, the deal involved a series of mergers: Helix converted from a Minnesota corporation to a Delaware corporation, a Helix subsidiary (Odyssey Sub, Inc.) merged into Hornbeck with Hornbeck surviving as a subsidiary of the renamed Helix Delaware entity, and one minute later that surviving entity merged into another Helix subsidiary (Hercules Sub LLC). Shares issued to most Hornbeck stockholders were registered under a Form S-4 (File No. 333-296508) declared effective by the SEC; shares issued to certain "Consenting Stockholders" who approved the deal by written consent (an aggregate of 37,818,435 shares) were issued under a private-placement exemption. Legacy Hornbeck warrant and equity awards were converted or assumed using the same 10.27167 exchange ratio mechanics.
The companies disclosed expected annual revenue and cost synergies of $75 million or more, to be achieved within three years of closing, driven by combined and integrated service offerings, cross-selling to existing customers, and fleet optimization that reduces reliance on third-party vessel charters. An investor presentation dated April 23, 2026 characterized the pro forma combined company as having more than $500 million of cash at closing and leverage of approximately 0.5 times net debt to the sum of Hornbeck's and Helix's 2025 Adjusted EBITDA (a non-GAAP measure), along with roughly $2.0 billion of total backlog as of year-end 2025. The same presentation stated that, before synergies, the pro forma combined company's 2025 revenue and 2025 EBITDA were approximately 106 percent and 56 percent higher, respectively, than Helix's standalone 2025 figures, though the filings reviewed did not provide the absolute dollar figures underlying those percentages.
Strategically, the companies described the merger as combining Hornbeck's high-specification offshore support vessel fleet with Helix's well intervention, robotics, and subsea trenching capabilities to create what they called "a premier integrated offshore services company" serving deepwater energy, defense and renewables customers. Owen Kratz, then President and CEO of Helix, said the transaction "creates a global deepwater vessel and services company with the scale and capabilities to deliver sustainable, long-term growth." At closing, Hornbeck said the merger brought together "Hornbeck's industry-leading marine expertise with Helix's differentiated robotics, well intervention and subsea capabilities."
Governance of the combined company was negotiated as part of the deal: the post-merger board was set at seven directors, four from the Hornbeck side (including Todd M. Hornbeck) and three from Helix, with William L. Transier (previously a Helix director) serving as Chairman and Todd M. Hornbeck serving as President and CEO. At the special meeting on August 31, 2026, Helix shareholders approved the share issuance (126,692,154 votes for, 644,096 against), an increase in authorized shares, the second-step merger, the plan of conversion to a Delaware corporation, and Jones Act compliance provisions in the new charter, each by wide margins.
The merger agreement provided for an Outside Date of December 31, 2026 (automatically extendable by 180 days in certain circumstances solely to obtain antitrust or foreign-investment regulatory clearances). It included customary no-shop and fiduciary-out provisions, and specified termination fees of $49,500,000 payable by Hornbeck (the "Company Termination Fee") and $40,500,000 payable by Helix (the "Parent Termination Fee") under specified circumstances, with smaller expense-reimbursement amounts ($16.5 million payable by Hornbeck and $13.5 million payable by Helix in certain non-approval scenarios) credited against any later-triggered termination fee. In connection with closing, Legacy Hornbeck's credit facilities were amended to permit the merger, and a First Incremental Facility Amendment increased total revolving commitments under Hornbeck's first-lien credit agreement to $125 million from $75 million, with uncommitted incremental capacity increased to $175 million. Helix's existing $120 million asset-based credit facility was terminated at closing, with no outstanding borrowings at that time.
On the financial advisory side, Hornbeck retained Barclays, J.P. Morgan and Piper Sandler & Co. as financial advisors, while Goldman Sachs & Co. LLC served as financial advisor to Helix, with Veriten LLC serving as an additional independent strategic advisor to Helix. On the legal side, Kirkland & Ellis LLP and Jones Walker LLP served as legal counsel to Hornbeck, and Baker Botts L.L.P. served as legal counsel to Helix; Joele Frank, Wilkinson Brimmer Katcher served as Helix's strategic communications advisor. The filings reviewed did not disclose a specific EPS accretion/dilution estimate, a tangible book value or earnback analysis, or a negotiation background/other-bidders narrative (such detail would typically appear in the "Background of the Merger" section of the definitive proxy statement/prospectus, which was referenced as filed July 31, 2026 but was not independently reviewed for this summary).
