Moat scores for companies ranked near SWX in Utilities - Regulated Gas
How SWX scores on the Regulated Utilities defenses
Regulatory Franchise
Score 36
· 25% of the moat score
The franchise is the moat, granted rather than earned: an exclusive right to serve a territory in exchange for regulated prices and an obligation to supply.
Rate-Base Return Quality
Score 53
· 20% of the moat score
A utility earns an allowed return on the capital invested in its network, the rate base.
Dividend Sustainability
Score 41
· 18% of the moat score
Utilities are owned largely for income, and the dividend is only as safe as the operating cash flow behind it.
Capital Structure Discipline
Score 68
· 17% of the moat score
Regulated utilities carry more debt than almost any other sector, which suits how predictable their revenue is but makes credit quality a core competitive asset.
Operational Efficiency
Score 86
· 12% of the moat score
Efficiency is unusually consequential under regulation.
Essential Service Resilience
Score 11
· 8% of the moat score
Electricity, gas and water are bought in a recession at close to the volume bought in an expansion, which is why utility revenue barely tracks the economic cycle.

The defenses are then weighted to produce the overall score out of 100.
Why is Southwest Gas Holdings, Inc. scored with the Regulated Utilities template?
A regulated utility is a legal monopoly whose prices are set by a regulator rather than by a market. It cannot raise prices at will and it cannot be undercut, so most of the usual questions about competitive advantage barely apply. What matters is the quality of the regulatory bargain: whether the company earns the return it is allowed, funds its capital programme cheaply, and sustains the dividend investors own it for.
Which competitive defenses are measured for Southwest Gas Holdings, Inc.?
The Regulated Utilities template measures 6 defenses, and SWX scores: Regulatory Franchise (36), Rate-Base Return Quality (53), Dividend Sustainability (41), Capital Structure Discipline (68), Operational Efficiency (86), Essential Service Resilience (11).
