Memo

Southwest Gas Holdings, Inc. (SWX). Latest full fiscal year: 2023; data up to 2026-06-30.

Figures computed from the financial statements: revenue 5.4 bn USD in 2023; YoY growth 9.6%; ROE 14.1%; net debt/EBITDA 3.8x.

The estimated value range is 93.29–110.32 USD per share (median of 3 methods, agreement: low); assumptions are illustrative. Against the central value of 105.53 USD, the price of 92.33 USD leaves a potential of 14.3% (value / price − 1) and a margin of safety of 12.5% (1 − price / value). The range is the median of the methods' low, central and high values, not a probability interval.

olivLaw score 31/100, methodological classification: unattractive profile (score, margin of safety and method agreement together; not a judgement of the right price). Groups assessed only in part: returns. Not investment advice.

Text generated deterministically from the figures shown; no language model. Not investment advice.

What supports the thesis

  • Revenue CAGR 3Y: 18.1%
  • P/E (TTM): 12.2x
  • The price is below the estimated value range

What contradicts it

  • ROIC: 4.4%
  • FCF conversion: -96.6%
  • EPS CAGR 3Y: -19.9%
  • Net debt / EBITDA: 3.8x
  • Interest coverage: 1.5x
  • Current ratio: 1.1x
  • EV/EBITDA: 11.8x
  • FCF yield: -7.9%
  • The valuation methods diverge

In brief

Southwest Gas Holdings is a holding company that distributes natural gas to residential, commercial and industrial customers in Arizona, Nevada and California, operating as a regulated distributor. After deconsolidating Centuri, it now focuses on its distribution segment, and a major transmission project, Great Basin 2028, defines its growth agenda. It serves roughly 2.3 million customers and generated an operating margin of 1.4 billion USD in fiscal 2025 12.

SWOT

Strengths

  • The customer base is large and diversified, with revenues almost entirely regulated and mechanisms that reduce the effect of weather and volumes on earnings 1.
  • The company is the largest regulated distributor in Arizona and Nevada, giving it a dominant position in its territories 1.
  • The balance sheet remains solid, with high available liquidity and capacity to finance investments 2.

Weaknesses

  • Reliance on delayed rate decisions can limit the speed of recovering infrastructure investments 1.
  • Revenues are seasonal, with large swings between quarters, which makes interim comparisons less meaningful 1.
  • The company had executive-level turnover in 2025, which could slow the execution of strategic plans 1.

Opportunities

  • The Great Basin 2028 project could open further phases after 2029, with rising commercial interest 3.
  • New customer growth and network expansion could sustain growth of the regulated asset base 1.
  • Accelerated investment mechanisms such as SIM could speed up recovery of safety-related costs 3.

Threats

  • Climate regulation and electrification could reduce demand for natural gas over the long term 1.
  • Inflation and high capital costs can hit margins if rates are not adjusted in time 1.
  • Difficulty obtaining labor and materials could delay or raise the cost of the Great Basin project 1.

Risks

  • Dependence on pipeline transporthigh

    Interruptions in interstate transport service could reduce supply, especially during the winter heating season 1.

  • Execution of the Great Basin 2028 projecthigh

    Shortages of labor and materials could delay the project or raise its costs above the estimated budget 1.

  • Rate delaysmedium

    If regulatory decisions are postponed, cost recovery may be delayed and affect cash flows 1.

  • Inflation and financing costsmedium

    Higher interest rates and operating costs could reduce earnings if rates do not offset the gap 1.

  • Climate risks and operational incidentsmedium

    Extreme weather or pipeline incidents could cause revenue losses and damage exceeding insurance coverage 1.

Investment thesis

What would need to be true (bull case)

  • If the Great Basin project advances on plan, the company could benefit from a growing regulated asset base and additional revenues 3.
  • Decoupling mechanisms and regulated rates provide margin stability, which supports earnings predictability 1.
  • The exit from Centuri simplified the structure, and a focus on distribution could improve operational clarity 1.

What would break the thesis

  • If rate decisions are delayed or more restrictive, cost recovery could be slower than the market expects 1.
  • Climate policies could reduce gas demand over the long term, which would limit volume growth 1.
  • Project costs could rise if labor or material shortages persist 1.

What to watch

  • Final CPUC decision on the cost-of-capital component of the California rate caseAugust 2026
  • Filing of the FERC certificate application for the Great Basin 2028 projectlater in 2026
  • Outcome of the Nevada general rate case and post-test-year plant adjustments2026
  • Five-year planning refresh and any revision of capital expenditure and earnings guidanceFebruary 2027

The business

Southwest Gas Holdings, Inc. is a holding company headquartered in Las Vegas whose main operator, Southwest Gas, purchases, distributes and transports natural gas for its customers 1. After the deconsolidation of Centuri in August 2025, the business consists solely of the natural gas distribution segment 1. The company served approximately 2,293,000 customers as of June 30, 2026, across Arizona, Nevada and California 2.

Revenue depends largely on operating margin, meaning regulated operations revenues less the net cost of gas sold, a non-GAAP measure used to analyze performance in a rate-regulated environment 1. The cost of gas is passed to customers without markup through PGA mechanisms, so its fluctuations affect revenues but not margin 1. Seasonal demand, which peaks in winter months, is moderated by decoupled rate structures in all three states 1.

Rates are set by the utility commissions of Arizona, Nevada and California, while FERC regulates the interstate transmission facilities of subsidiary Great Basin 1. The company keeps investing in infrastructure to support population growth and system integrity, with capital investment reaching 840.2 million USD in 2025 1.

Segments

Natural Gas Distribution

This is the only reportable segment after August 2025 and brings together Southwest Gas operations, the largest regulated distributor of natural gas in Arizona and Nevada 1. The segment's operating margin was 1,444.8 million USD in fiscal 2025 1.

Interstate Transmission (Great Basin)

Southwest Gas subsidiaries operate two regulated interstate pipelines, including Great Basin, serving parts of Nevada and California 2. The Great Basin 2028 expansion is the main long-term growth driver, with an estimated investment of about 2.3 billion USD 3.

Market context

The company's core market is natural gas distribution in Arizona, Nevada and California, where Southwest Gas is the largest regulated distributor in Arizona and Nevada 1. Residential and commercial customers make up over 99% of the customer base 2. Customer growth comes from new construction, and in 2025 the company supplied gas to a large majority of new homes in its major metropolitan markets 1.

Demand is shaped by climate, population growth and competition from electricity, the principal competitor in the residential and small commercial segment 1. In 2025, about 53% of operating margin came from Arizona, 35% from Nevada and 12% from California 1.

Trends

  • Great Basin 2028 Projecttailwind

    Binding contracts have grown to about 1 Bcf per day, and the company estimates annual margin of 270 to 300 million USD once in service, which could support growth of its regulated asset base 3. FERC approval remains an essential condition.

  • Recovery of infrastructure investmenttailwind

    The Arizona SIM and Nevada rate filings allow faster recovery of investments, if regulatory processes stay favorable 3. Rate delays, however, could reduce this recovery.

  • Cost of capital and inflationheadwind

    High interest rates and inflation raise financing and operating costs, and if rates do not offset them, margins could be affected 1. Pressure grows when inflation exceeds rate adjustments 1.

  • Climate policy and electrificationmixed

    Legislation limiting emissions or promoting electrification could reduce demand for natural gas or raise compliance costs, though the effect remains uncertain 1. Renewable energy standards could also reduce demand for renewable gas projects 1.

Competitive position

The company's main competitor is electricity, especially for space heating and small commercial needs, where the equipment choice is made at installation 1. Once a energy source is chosen, customers generally keep it for the life of the equipment 1.

Southwest Gas strengthens its position through relationships with home builders and regulators, so that gas infrastructure is included in new developments 1. The company has no dependence on a few major customers, which reduces concentration risk 1.

  • Electric utilities in the served areas

    Direct competition for heating and household needs, mainly at the equipment installation stage 1.

  • Transport operators and other interstate pipelines

    Compete for transport capacity and pipeline contracts in the region, including through alternative projects 1.

  • Other gas distributors in the region

    May compete for network extensions and rate approvals in neighboring territories 1.

  • Storage and regasification operators

    Provide storage services that influence access to supply and operational flexibility 1.
