HOS vs OII: Which Is the Better Buy in 2026?
Last updated October 2026
Short answer
OII is the larger of the two ($4.36B market cap): the incumbent the market prices for continued execution (18.88x forward earnings, beta 1.25). HOS is the smaller challenger ($2.32B), cheaper on forward earnings (13.15x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.
HOS vs OII: the tie-breaker metrics
Same yardstick, side by side (as of October 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | HOS | OII | What it tells you |
|---|---|---|---|
| Market cap | $2.32B | $4.36B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 13.15 | 18.88 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 16.90 | 12.66 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Price vs 52-week range | 20% of range | 67% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
Reading it: HOS is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.
Before you buy: how HOS and OII affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. HOS and OII share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined HOS and OII exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does Hornbeck Offshore Services (HOS) do?
Hornbeck Offshore Services (NYSE: HOS) is a Covington, Louisiana company that took its current shape on September 1, 2026, when Helix Energy Solutions Group completed an all-stock combination with privately held Hornbeck Offshore. Helix was the legal acquirer and its listing survived, but it took the Hornbeck name, the HOS ticker and Todd Hornbeck as CEO, and former Hornbeck holders own ~55% of the company. The combined fleet counts 85 vessels: 57 offshore supply vessels (22 ultra high-spec), 15 multi-purpose support vessels including two 400-class newbuilds due in 2027 and 2028, seven well intervention vessels, plus 41 work-class ROVs and six subsea trenching systems. Fifty-seven vessels are U.S. Jones Act qualified.
What does Oceaneering International (OII) do?
Oceaneering International is a Houston-based technology and engineering company that serves the offshore energy industry and, increasingly, aerospace and defense customers. It operates through five segments: Subsea Robotics (its largest, built around the world's most widely used fleet of remotely operated vehicles, or ROVs, plus tooling and survey services), Manufactured Products (subsea umbilicals, field-development hardware, connection and repair systems, and industrial mobile robotics), Offshore Projects Group (installation, intervention, and inspection services), Integrity Management and Digital Solutions (asset integrity and software), and Aerospace and Defense Technologies (engineering and manufacturing for government customers). Revenue is generated primarily from day rates on ROV and vessel work, project execution, and product backlog conversion, with results driven by offshore drilling and production activity worldwide.
HOS vs OII: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- HOS drivers: Merger synergies and integrated selling; Deepwater well intervention dayrates.
- OII drivers: Offshore Energy Capital-Spending Cycle; ROV Fleet Utilization and Day Rates.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The largest near-term risk is share supply. For OII, oceaneering's results are closely tied to offshore oil and gas capital spending, so a sustained drop in crude prices or a pullback in deepwater sanctioning could quickly reduce ROV utilization and project activity.
HOS or OII: which should you pick?
Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick HOS if you believe its drivers more; OII if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the HOS and OII guides.
HOS vs OII: the full fundamentals
HOS. At ~$6.70 the shares value the company at an enterprise value of roughly ~$2.45B, or about 4.4x trailing pro forma adjusted EBITDA and around 8x to 9x adjusted free cash flow. On pro forma 2025 earnings of ~$0.50 per share the P/E is about 13x, though that figure is depressed by one-time merger costs and stock awards. Larger offshore peers have often traded at higher EBITDA multiples, so the discount mostly reflects the resale overhang, oil exposure and the absence of a combined reporting history. The November 5, 2026 report will be the first clean read.
OII. The multiple has re-rated with the stock: EV/EBITDA has moved to about 11 times from the 7 to 8 times range earlier in 2026, and the forward P/E near 19 is higher than the trailing 12.6 because analysts expect 2026 EPS of about $2.06 and 2027 EPS near $2.32, below the trailing figure. Cash of about $636 million against roughly $822 million of debt keeps the balance sheet far stronger than in prior downturns. The valuation still prices cyclical exposure, and the October 21, 2026 report will test whether the second-quarter strength carries through.
Headline figures (approximate, October 2026): HOS shows revenue (ttm, pro forma) ~$1.88 billion (12 months to June 30, 2026), adjusted ebitda (ttm, pro forma) ~$551 million (~$281M legacy Hornbeck, ~$270M legacy Helix), net income (pro forma) ~$164M for 2025 (~$0.50/share); ~$56M in H1 2026 (~$0.17/share), net debt / leverage ~$238 million, ~0.4x EBITDA; ~$618M liquidity; OII shows revenue (ttm) ~$2.87 billion, revenue (q2 2026) ~$768 million, up ~10% year over year, eps (q2 2026) ~$0.63 vs ~$0.45 expected, margins (ttm) ~11.5% operating, ~12.2% net.
The bottom line: HOS vs OII
HOS and OII are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined HOS and OII exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between HOS and OII?
+
Hornbeck Offshore Services (NYSE: HOS) is a Covington, Louisiana company that took its current shape on September 1, 2026, when Helix Energy Solutions Group completed an all-stock combination with privately held Hornbeck Offshore. Oceaneering International is a Houston-based technology and engineering company that serves the offshore energy industry and, increasingly, aerospace and defense customers. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is HOS or OII the better stock?
+
Neither is universally better. OII is the larger incumbent; HOS is the smaller challenger and looks cheaper on forward earnings. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, HOS or OII?
+
On forward P/E (as of October 2026), HOS trades at 13.15x and OII at 18.88x, so HOS is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both HOS and OII?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of HOS vs OII?
+
HOS: The largest near-term risk is share supply. A September 15, 2026 shelf lets holders from Hornbeck's 2020 bankruptcy resell up to ~155M shares, close to half the ~327M fully diluted count, led by Ares (~26.5%), Whitebox (~15.2%) and Highbridge (~7.6%). Repeated Form 144 filings show sales have begun, and the stock lost about a third of its value in seven weeks. About 72% of revenue comes from oil and gas customers, so a fall in oil prices or deepwater budgets would hit utilization and dayrates, which drive most of the profit. Well Intervention depends on a few very expensive vessels; one dry dock, a contract gap or a long transit like the Q7000's can move a quarter's results. Integration of two companies with different cultures and systems carries execution risk, and the $75M synergy target is a management estimate. Reported earnings will be noisy, with purchase accounting, ~$46M of merger costs and large stock compensation. The two chartered Siem vessels carry lease obligations. Jones Act protection is a political choice that could change. Finally, there is no dividend, no combined guidance yet and limited analyst coverage. OII: Oceaneering's results are closely tied to offshore oil and gas capital spending, so a sustained drop in crude prices or a pullback in deepwater sanctioning could quickly reduce ROV utilization and project activity. ROV fleet utilization softened in early 2026 and first-quarter EPS fell year over year even as revenue rose, showing how margin-sensitive the business is, before a stronger second quarter. The company competes against larger integrated subsea players and faces project-execution, contract-timing, and international-operations risks. Currency swings, cost inflation, and the lumpiness of large project awards add quarter-to-quarter volatility, and the aerospace and defense unit, while diversifying, remains a minority of total revenue. After a near doubling in the share price over twelve months, expectations are also higher: the forward P/E of about 19 is well above the trailing 12.6, because trailing net income of about $350 million is expected to fall back toward roughly $2.06 a share for 2026.
