The line below covers up to 5.2 years and opens on the 5Y view; the buttons cut it shorter. Over the last two years (104 weeks) this industry is 10% behind S&P 500. Earnings across its companies grew 12% on average over the last four reported quarters.

5 of 16 companies ahead of S&P 500 by 5% or more over three months. 1 is 20% or more behind over a year while earnings grew 20% or more.

Ahead of S&P 500 on the three-month view for 1 week running; 11 of the 16 companies in the industry index above their 200-day average (8 more than four weeks earlier); 5 of those 16 ahead of S&P 500 by 5% or more over three months (5 more than four weeks earlier); earnings rising at 11 of the 16 that report earnings.

Ahead of S&P 500 for 1 week after being behind, with 0 → 5 of 16 participating. Earnings confirming, 11 of 16 members have higher trailing twelve-month earnings than a year ago.

Both lines start at 200 in the same week, so the gap between them tells the story: the industry line is an equal-weighted index of its 16 companies. The bars underneath are trailing 12-month earnings per share, one bar per reported quarter, each member set to 100 at the start and the industry taking the middle value, so a price line pulling away from flat bars means the market is paying more for the same earnings. A bar turns grey when that figure is lower than the quarter before. The rules are fixed and the same everywhere on this site: ahead by 5% or more over three months, or behind by 20% or more over a year while earnings grew 20% or more. Hover or tap any point to read both values and the gap.

Utilities - Regulated Gas has done worse than the S&P 500 by 8.4% over the last 52 weeks. Over 13 weeks the gap is a lead of 0.7%. Black Hills Corporation is the strongest against the sector itself at +15.3%.

Utilities - Regulated Gas has done worse than the S&P 500 by 8.4% over 52 weeks, but is 0.7% ahead over the last 13 weeks. 2 of 16 companies we track are beating the S&P 500 on relative strength (how a share price has done against the index over recent months), and 11 of 16 are ahead of the industry itself.

A score that ranks each company against the others in its industry. The four parts shown always add up to the total: Growth & earnings (35), Capital efficiency (25), Valuation (20), and Relative strength (20). Missing or old evidence affects only its own part, never as a hidden adjustment.

Chesapeake Utilities Corporation has the strongest current balance of earnings trajectory, business quality, valuation and price confirmation, with 78.6% evidence confidence.

UGI Corporation scores well on valuation against its peers or its own history, but its earnings have not yet improved enough to back that up.

Black Hills Corporation has the strongest one-year price move in Utilities - Regulated Gas at +20.8%. It also leads on relative strength against the S&P 500, at +7.8%. 2 of 16 companies we track are ahead of the index on that measure. Every line covers 314 weekly closes through 4 November 2026.

Price and relative strength

Price · same starting point: Every company, the sector's own index and S&P 500 all start level on the left edge of the window, so only the distance between the lines counts: the highest line has risen the most since then, and the chart at the top of this page is drawn the same way. It opens on one year; the buttons beside it stretch that to three or five.

RS vs S&P 500: How far ahead of or behind S&P 500 each company has been running, measured against its own recent average of that comparison, so the flat line at zero IS S&P 500: above it the company is beating the market, below it the market is beating the company. It opens on one year.

RS vs sector: The same measure taken against Utilities - Regulated Gas itself instead of the whole market, so the flat line at zero is the sector: above it the company is beating its own peers, which is the sharper test of the two. It opens on one year.

UGI Corporation has the highest Revenue among the 16 Utilities - Regulated Gas companies compared here, at $7,296 million. NiSource Inc. is next at $6,881 million. Centuri Holdings, Inc. has the highest Revenue growth at 25.2%, so level and change sit with different companies. 16 of 16 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: UGI Corporation is the largest at $7,296 million, 6% ahead of NiSource Inc. Centuri Holdings, Inc.'s growth is 25.2% from a $3,394 million base, with 14 reported quarters out of the last 20. Fast growth from a smaller base is not yet the same as proven size.

What this means: UGI Corporation is the size to compare against; Centuri Holdings, Inc. is the one growing fastest. The faster grower has to keep that growth and turn it into margin and returns before it counts as more than a fast start.

This conclusion weakens if: UGI Corporation's growth falls below Centuri Holdings, Inc.'s for two consecutive comparable reports while operating margin also compresses.

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

All-company data · latest reported quarter

In every all-company table on this page, each figure is the company’s latest single reported quarter. The rankings above them use trailing-twelve-month or current-market values, so a company can legitimately show a different number in each.

Revenue shows both size and speed. A large company can absorb shocks and pay for wide distribution; faster growth can mean market-share gains, new capacity or stronger demand. The best sign is usually growth that lasts without hurting margins and returns.

UGI Corporation has the highest OPM among the 16 Utilities - Regulated Gas companies compared here, at 25.5%. Atmos Energy Corporation is next at 22%. OPAL Fuels Inc. has the highest Margin change at +5.6 percentage points, so level and change sit with different companies. 15 of 16 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: UGI Corporation leads opm at 25.5%; OPAL Fuels Inc. leads margin change at +5.6 percentage points.

What this means: UGI Corporation sets the level to compare against; the company improving fastest needs another report to confirm the change.

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

Operating margin compares operating profit with revenue. Improvement is measured in percentage points, not percentage growth.

Atmos Energy Corporation has the highest Net profit among the 16 Utilities - Regulated Gas companies compared here, at $1,403 million. NiSource Inc. is next at $978 million. Spire Inc. has the highest Profit growth at 96.7%, so level and change sit with different companies. 16 of 16 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: Atmos Energy Corporation earns the most, $1,403 million of profit over the last 12 months, 43.5% above NiSource Inc. Spire Inc. shows 96.7% growth from a profit base of $531 million. A fast rate from a small base matters less than a large profit that keeps coming.

What this means: Atmos Energy Corporation sets the level to compare against; the company improving fastest needs another report to confirm the change.

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

Net profit is the residual after operating costs, interest and tax. Growth off a loss or near-zero base is excluded from the fastest-grower rank.

Brookfield Infrastructure Corporation has the highest ROCE among the 16 Utilities - Regulated Gas companies compared here, at 13.6%. Suburban Propane Partners, L.P. is next at 10%. Southwest Gas Holdings, Inc. has the highest ROCE change at +1 percentage points, so level and change sit with different companies. Its ROCE series carries 20 reported observations across the 20-quarter window.

What the numbers say: Brookfield Infrastructure Corporation leads ROCE at 13.6%, 3.6 percentage points above Suburban Propane Partners, L.P. A high return reported once may be one good year; a high return reported year after year shows a lasting business.

What this means: Brookfield Infrastructure Corporation sets the level to compare against; the company improving fastest needs another report to confirm the change.

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

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.

Suburban Propane Partners, L.P. has the lowest PEG among the 16 Utilities - Regulated Gas companies compared here, at 0.27×. Spire Inc. is next at 0.4×. Brookfield Infrastructure Corporation has the lowest P/E at −31.4×, so level and change sit with different companies. 12 of 16 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: Suburban Propane Partners, L.P. has the lowest comparable PEG at 0.27×, 32.5% below Spire Inc. That would need today's multiple, the company's own history and steady growth to agree.

What this means: A low valuation is a reason to look closer at the business, not a conclusion on its own.

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

PEG is shown only when earnings are positive and three-year EPS growth is between 5% and 60%. It is worked out the same way every time, as the P/E on the last 12 months of reported earnings divided by that growth rate, never on expected earnings. 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.

This Utilities - Regulated Gas comparison names 4 specific ways its own evidence can mislead, all listed below. All 16 companies here report on comparable dates, so no rank carries a stale marker. A high growth rate can still come from a very small starting figure.

Keep these limits visible

• A high growth rate can come from a very small starting figure. The page keeps level and change separate for that reason.
• A high ROCE can be temporary, or look high because the capital base is small. It is best read beside margin, cash flow and how much is spent back on the business.
• The 4-Factor Sector Score ranks published data only. Management quality, upcoming events and risks are not part of it.
• An “all companies” line chart preserves completeness, but rank changes should be checked against reporting dates before drawing a conclusion.

This comparison is built from the reported filings of 16 Utilities - Regulated Gas companies, normalized to a common $ scale and a shared quarter axis of up to 20 quarters each. Fundamentals run through Jun 2026 and market data through 4 November 2026.

These 22 answers restate the Utilities - Regulated Gas comparison above in question form. Every one is computed from the same 16 companies and the same reported filings as the rankings and charts, current through Jun 2026. Price and relative-strength answers run through 4 November 2026. Nothing here is estimated, and none of it is a recommendation.
