## 4-Factor Sector Score

An additive sector-relative research score. The four displayed point contributions always equal the total: Growth & earnings (35), Capital efficiency (25), Valuation (20), and Relative strength (20). Missing or stale evidence is absorbed inside the affected factor, never applied as a hidden adjustment.

1. Nabors Industries Ltd. (NBR): 59/100 — Thin evidence · provisional; evidence 52%
   - Growth & earnings 19.1/35 | Capital efficiency 11.5/25 | Valuation 11.5/20 | Relative strength 17.0/20
   - Price stage: ASLEEP — Neither ahead of the benchmark nor yet turning up against it.

## Revenue Scale & Growth Durability

What the numbers say: Transocean Ltd. is the scale leader at $4,140 million, 3.4% ahead of Helmerich & Payne, Inc.. Helmerich & Payne, Inc.'s growth is 29.7% from a $4,002 million base, with 19 reported observations in the 20-quarter window. Treat the growth leader as an acceleration candidate, not as equally proven scale.

Investor read: Transocean Ltd. is the scale benchmark; Helmerich & Payne, Inc. is the acceleration watch. Promote the challenger only if growth persists and converts into margin and returns.

This conclusion weakens if: Transocean Ltd.'s growth falls below Helmerich & Payne, Inc.'s for two consecutive comparable reports while operating margin also compresses.

Evidence: Transocean Ltd. · $4,140 million | 3.4% versus #2 · Helmerich & Payne, Inc. | 8/8 recent comparable periods | 5/10 companies · 166 observations

Definition: Revenue is compared on a common reported-currency basis. Growth is year-on-year, so seasonality does not masquerade as progress.

## Operating Economics & Margin Trend

## Profit Scale & Acceleration

What the numbers say: Valaris Limited leads with $1,000 million of TTM profit, 30.3× the profit of Borr Drilling Limited. Helmerich & Payne, Inc. shows -266.2% growth from a $369 million net cash profit base. Compare the size of the base and persistence before ranking acceleration above profit scale.

Investor read: Valaris Limited sets the level benchmark; use the change leader as an inflection watch only after another comparable report confirms it.

This conclusion weakens if: The next two comparable reports reverse the current profit growth signal.

Evidence: Valaris Limited · $1,000 million | 30.3× versus #2 · Borr Drilling Limited | 4/8 recent comparable periods | 6/10 companies · 184 observations

## Return On Capital Employed

What the numbers say: Transocean Ltd. leads ROCE at 1.8%, 0.4 percentage points above Borr Drilling Limited. Transocean Ltd. has the strongest latest improvement at +1.4 percentage points. Read the leader beside the density of its reported history: a sparse high return is a candidate; a repeated high return is evidence of durability.

Investor read: Transocean Ltd. sets the level benchmark; use the change leader as an inflection watch only after another comparable report confirms it.

This conclusion weakens if: The next two comparable reports reverse the current roce change signal.

Evidence: Transocean Ltd. · 1.8% | 28.6% versus #2 · Borr Drilling Limited | 4/8 recent comparable periods | 10/10 companies · 192 observations

Definition: ROCE asks how much operating return the business earns on the capital employed. Direction matters, but a single exceptional year should not be mistaken for durability.

## Valuation Against Growth & Quality

What the numbers say: There is not enough comparable evidence to name a reliable peg leader.

Investor read: Treat valuation as permission to investigate, never as a standalone reason to buy.

This conclusion weakens if: The next two comparable reports reverse the current p/e signal.

Evidence: No comparable leader | Not enough peers | Not enough history | 0/10 companies · 5 observations

Definition: PEG is shown only when earnings are positive and three-year EPS growth is between 5% and 60%. It is recomputed consistently as the trailing P/E divided by that growth rate — reported earnings, never an expected-earnings multiple. On Indian companies it is shown only where the two data feeds agreed. Where any of that fails the ratio is left out rather than printed: a P/E divided by a loss, or by growth measured off a tiny base, is a number that looks precise and means nothing.

## What can make this comparison misleading?
- A high growth rate can be a low-base artefact. The page keeps level and change separate for that reason.
- A high ROCE can be temporary or flattered by a small capital base. Read it beside margin, cash conversion and reinvestment.
- The 4-Factor Sector Score ranks research priority, not portfolio action. Management quality, catalysts and risks need equally fresh evidence before capital is deployed.
- An “all companies” line chart preserves completeness, but rank changes should be checked against reporting dates before drawing a conclusion.
- Thin comparisons: Valuation have fewer than three usable current readings.

Noble Corporation plc has the highest operating margin at 28.7%, from 9 of 10 comparable companies. Transocean Ltd. shows the biggest recent improvement, at +19.4 percentage points. A high margin matters most when it is holding or rising, not when it is peaking.

### Which Oil & Gas Drilling company earns the highest return on capital?

Transocean Ltd. leads on return on capital employed at 1.8%, across 10 of 10 companies. Read it beside the length of its reported history: a high return that repeats for years is evidence of a durable business, while a single high reading can be a small capital base or one good year.

### Which Oil & Gas Drilling stock has the strongest price momentum?

Nabors Industries Ltd. scores 59.1 out of 100 with 51.8% evidence confidence, from 19.1 points on growth and earnings, 11.5 on capital efficiency, 11.5 on valuation and 17 on relative strength. This ranks what deserves work next. It is not a buy recommendation, and management quality, catalysts and risk still need separate research.

It compares 10 listed companies over up to 20 reported quarters of fundamentals, ending Jun 2026, plus weekly price and relative-strength history. Membership is the full sector list — nothing is dropped for having thin data.

The 10 Oil & Gas Drilling companies on this page carry $31,994 million of combined market value. Noble Corporation plc is the largest at $6,518 million, about 20% of the sector's total on its own. Market value moves with price, so this reading is dated 2026-08-04.

The median price-to-earnings ratio across the 10 Oil & Gas Drilling companies on this page is 38.5×, measured on the 9 that report a comparable figure.

3 of the 10 covered Oil & Gas Drilling companies are beating S&P 500 on Mansfield relative strength. The sector itself is 28.7% ahead of S&P 500 over 52 weeks on an equal-weight index of its current members. Readings are as of 2026-08-04.

This comparison covers 10 listed Oil & Gas Drilling companies in the US, each above the size floor the site applies. The full ranked list is on this page, with reported fundamentals through Jun 2026. Membership is the full industry list — nothing is dropped for having thin data.

### Why are some values on this page blank?

A blank means that company did not report a comparable figure for that period, so nothing is shown. Missing observations are never interpolated, carried forward, or replaced with a similar-looking accounting line, and a company with missing evidence has its research score pulled toward neutral rather than being scored as bad.

### Is this investment advice?

No. Every figure here is a deterministic calculation from reported company filings and market data, published for research. It contains no recommendation to buy or sell any security, does not account for your circumstances, and is not a substitute for advice from a licensed adviser.
