HORNBECK OFFSHORE SERVICES, INC. (HOS) stock intrinsic value fair value estimate & owner earnings analysis

Hornbeck Offshore Services (NYSE: HOS) is a new company. On 1 September 2026, Helix Energy Solutions combined with privately held Hornbeck Offshore in an all-stock deal. Hornbeck's owners received about 55% of the combined company and Helix's shareholders about 45%. There are now roughly 327 million fully diluted shares, against about 148 million Helix shares before the deal. Our previous estimates were per Helix share, for a business roughly half this size, so they are not comparable with the figures below. The combined company has three lines of business. Well intervention ($851 million of revenue over the twelve months to June 2026) uses seven specialised vessels, including the Q5000, Q7000 and the Siem Helix 1 and 2, to work on live subsea wells. The Siem Helix vessels are contracted to Petrobras in Brazil into 2028, and Shell has been the largest customer. Marine transportation and specialty ($606 million) is legacy Hornbeck: 57 offshore supply vessels and multi-purpose support vessels qualified under the Jones Act, most working in the Gulf of America, plus a 20-year relationship with the US military, including operating four Navy-owned vessels. Subsea services ($414 million) covers ROVs, trenchers and the Helix Producer I production facility. Helix sold its shallow-water decommissioning business (Helix Alliance) on 1 May 2026 for about $104 million. Contracted backlog is about $2.0 billion, close to one year's revenue. Earnings. We measure owner earnings as operating cash flow, stripped of working-capital swings, minus share-based pay and the capital spending needed to keep the fleet as it is. On that basis Helix earned $163 million in 2025, $215 million in 2024 and $201 million in 2023, after a weak 2020-2022 of $50-118 million. In 2016-2017, while Helix was building vessels in an offshore downturn, owner earnings were negative. Two judgements matter. First, the cash Helix and Hornbeck spend on regulatory recertification and dry-docking ($52 million at Helix in 2025, $76 million at Hornbeck over the twelve months to June) is treated as a real cost of keeping the fleet, not as an optional investment. Second, Helix's book depreciation of about $187 million a year is well above its cash maintenance spending of about $68 million. Most of that gap reflects vessels built in 2015-2019, whose cost is now sunk. Those vessels will eventually need replacing, and we charge that later in the story rather than in today's earnings. Helix's operating cash flow in 2024 also included a $58 million acquisition earnout payment, which we add back because it was part of a purchase price, not an operating cost. Hornbeck's own audited cash-flow statements were not available to us in full. For legacy Hornbeck we use the combined company's published reconciliation, which deducts dry-docking, maintenance capital, interest and taxes. It shows about $115 million of free cash after interest over the twelve months to June 2026 and $137 million in the year before, with $43 million of cash interest. Adding back interest, legacy Hornbeck's business produces roughly $160-180 million a year before lenders. Helix's continuing business produces roughly $175-200 million before interest in a normal year, which is its 2023-2025 median adjusted for the sale of Alliance. The combined business therefore earns about $310-330 million a year before interest, or roughly $0.95-1.00 a share after share-based pay. We anchor on 2023-2025 because these are the first years of the current fleet working at near-full utilisation and the first years Hornbeck was out of restructuring. We treat 2016-2022 as a different, building-and-bust phase of Helix. On recent trends, Helix's owner earnings fell 24% in 2025. On the combined company's published basis, adding back interest and deducting share-based pay, the two businesses together rose about 8% over the twelve months to June 2026, to roughly $350 million: Helix's continuing operations rose and Hornbeck's fell 16%. The base case assumes no growth from there. Its first year is about $310 million, below that trailing level, because legacy Hornbeck's results are declining and Helix has two major vessel surveys scheduled for 2026. Base case ($10.97 a share). The base case uses what is contracted and demonstrated. The combined business produces $310-325 million a year before interest through 2031, and this is supported by the $2 billion backlog and the Petrobras and Navy contracts. Two 400-class MPSVs that are already largely built are delivered in 2027 and 2028 and absorb their remaining completion cost. We give no credit for the $75 million of announced cost and revenue synergies, for reactivating the up-to-24 stacked vessels, or for higher dayrates, because none of these is yet delivered or contracted. From 2032 the earning power tapers to about $190 million a year to pay for replacing the 2010s-built well-intervention fleet, which carries more than $180 million a year of depreciation. That leaves the business worth about $4.0 billion. It owes about $769 million: Helix's 9.75% senior notes due March 2029 ($300 million), MARAD debt, Hornbeck's second-lien term loans due 2033 and $25 million drawn on the revolver. Against that it holds about $418 million of cash above a $100 million operating reserve, after the roughly $230 million of deal costs and cash adjustments. We add about $60 million because the 9.75% notes and Hornbeck's second-lien loans cost well above market rates. Net debt is about $411 million, leaving $3.59 billion of equity, or $10.97 a share. Bear case ($4.94 a share). Offshore service companies have repeatedly had their earnings wiped out when oil companies cut spending. The bear case repeats the 2015-2017 offshore downturn, which Helix itself went through: its owner earnings went from positive to roughly minus $120-170 million a year. Hornbeck went into Chapter 11 in 2020 with about $1.3 billion of debt. In the bear case, two good years from today's backlog are followed by three years in 2028-2030 when the combined business makes only $20-60 million a year before interest. Supply vessels are stacked again, well-intervention dayrates are cut on renewal, and Petrobras does not renew the Siem Helix vessels in 2028. Recovery takes the business back to about $200 million a year, and it settles at $100 million after vessel replacement. The debt survives the downturn, because the company enters it with about $420 million of spare cash and the 2029 notes can be repaid from cash. Refinancing in a trough would cost more, and we add about $60 million to the debt for that. The business is worth about $2.1 billion, owes about $471 million, and leaves $1.61 billion, or $4.94 a share. Bull case ($15.65 a share). The bull case adds what the combined company's own levers can deliver if they work: both MPSV newbuilds contracted on delivery, a large part of the stated synergies, and the 2025-2026 well-intervention renewal rates holding. The business earns about $400-410 million a year before interest at peak, tapering to $290 million after fleet replacement. It is worth about $5.5 billion, owes about $411 million, and leaves $15.65 a share. What could make this wrong. The company is newly combined, so the earnings level rests on legacy Hornbeck figures that we could not reconcile line by line against an audited cash-flow statement. The biggest uncertainty is how long today's offshore cycle lasts. A second is whether Hornbeck's Jones Act fleet keeps its pricing: the Jones Act limits US coastwise work to US-built vessels, and changes to that law would hurt Hornbeck. A third is vessel replacement cost, which we may be underestimating. We also note that former Hornbeck owners hold a majority of the shares. How we set the margin-of-safety price. We are moderately confident in the earnings level: three years of Helix cash flows reconcile to its audited statements, while Hornbeck's half rests on a reconciliation published for the merger. The worst plausible outcome is a long offshore downturn like 2015-2017. The balance sheet would survive it: net debt is modest, the only large maturity is the March 2029 notes, and there is cash to cover them. The fleet would be stacked and worth far less, though. If we are wrong about both the earnings level (say 20% lower) and the depth of the downturn, the shares are worth roughly $3.50-4.00. While waiting, the business pays little: there is no dividend, and buybacks have been only about a quarter of free cash flow. The price assumes it may take four or five years to reach the base value. At $5.00 a share, the bear case implies roughly breaking even, and the base case reached over four years implies a little over 20% a year. A higher price would rely on the cycle holding. So the margin-of-safety price is $5.00.
