Helix Energy Solutions Group shareholders have approved the all-stock merger with Hornbeck Offshore Services, paving the way for the creation of a combined offshore energy services company.
The transaction, valued at approximately $2.3 billion on a fully diluted basis, will result in Hornbeck securityholders owning about 55% of the combined entity, while Helix shareholders will retain roughly 45%. The merged company will operate under the name Hornbeck Offshore Services Inc. and will list on the New York Stock Exchange under the ticker symbol HOS.
Helix, headquartered in Houston, provides specialty offshore services including well intervention, robotics, and decommissioning operations. Hornbeck, based in Covington, Louisiana, supplies offshore service vessels primarily in the Gulf of Mexico and Latin America, serving energy clients as well as the U.S. government and offshore wind sectors.
The merger is expected to close on September 1, 2026, subject to customary regulatory approvals and final filings. Helix will file the final voting results on a Form 8-K with the U.S. Securities and Exchange Commission.
Goldman Sachs & Co. LLC and Veriten LLC served as financial advisors to Helix, while Baker Botts L.L.P. provided legal counsel. Hornbeck’s financial advisors included Barclays, Piper Sandler & Co., and J.P. Morgan, with Kirkland & Ellis LLP handling legal matters for the company.
