Southwest Gas Holdings, Inc. — 2020 Form 10-K Summary
Reporting period: Fiscal year ended December 31, 2020. This combined annual report covers Southwest Gas Holdings, Inc. and its wholly owned subsidiary, Southwest Gas Corporation. The supplied filing text incorporates the financial statements and MD&A by reference to the 2020 Annual Report to Stockholders but does not include their detailed figures.
Business context
The company operates two segments: regulated natural gas distribution and transmission through Southwest Gas Corporation, serving customers in Arizona, Nevada, and California; and utility infrastructure services through Centuri Group, Inc., which works for gas and electric utilities in the U.S. and Canada. Natural gas operations are seasonal, with higher demand in winter; Centuri’s activity is generally strongest in summer and fall.
Key metrics and financial information available in the supplied text
- Natural gas customers: 2.123 million at year-end 2020; 37,000 customers were added during the year. Management expected similar customer growth in 2021.
- Utility plant: Southwest Gas had $8.6 billion of gas plant, including construction work in progress, at December 31, 2020.
- Operating-margin mix: Natural gas distribution margin was 85% residential and small commercial, 3% other sales, and 12% transportation in 2020, compared with 84%, 3%, and 13%, respectively, in 2019.
- Centuri: Approximately $100 million of backlog related to outstanding fixed-price contracts at year-end. About 92% of 2020 revenue was earned under unit-price and time-and-materials contracts. Southwest accounted for approximately 7% of Centuri revenue; another customer accounted for about 11%, and four others each represented at least 5%. More than half of Centuri revenue came from nine customers.
- Variable-rate debt: $560.3 million in total across Southwest Gas, Centuri, and corporate borrowings at year-end, versus $715.8 million in 2019. A hypothetical 1 percentage-point rate increase would raise annual interest expense by an estimated $5.60 million, assuming balances remained constant. These amounts are not total debt.
- Dividends: In February 2021, the board raised the quarterly dividend from $0.570 to $0.595 per share, a 4.4% increase, effective with the June 2021 payment.
- Revenue, net income, cash flow, margins in dollars, total debt, and liquidity: The supplied text does not provide clear annual values. It refers readers to financial statements and MD&A incorporated by reference.
Material changes and outlook
- Arizona general rate-case rates became effective in January 2021; Nevada rates became effective in October 2020. The California general rate case remained pending in the filing.
- Southwest reported that decoupled rate mechanisms in all three states are designed to stabilize annual operating margin against changes in gas usage. Purchased-gas adjustment mechanisms permit recovery of gas-cost changes, but affect cash flow and short-term borrowing needs rather than profit margin directly.
- For periods after October 2020, Southwest did not plan broad fixed-price term purchases or swap transactions in Arizona and Nevada, while continuing fixed-price purchases in California. Management described adequate contracted firm transportation and supply for forecast peak-day needs.
- Centuri’s work is exposed to customer utility budgets and regulatory approvals. The company cited pipeline-replacement and safety requirements, including PHMSA’s 2020 “Mega Rule,” as drivers of infrastructure work.
Risks, contingencies, and unusual items
- COVID-19: The company warned of potential effects from customer payment difficulties, suspended disconnections and waived fees, supply-chain disruption, delayed Centuri projects, possible workforce impacts, and reduced access to capital. Recovery of related costs through regulation was uncertain.
- Regulation and cost recovery: Rate decisions, regulatory lag, disallowance of costs, or changes to decoupling and infrastructure-replacement programs could affect earnings, cash flows, and liquidity.
- Supply and weather: Interruptions to interstate pipeline capacity or gas supplies could impair service and financial results, particularly in winter. Gas-cost increases can increase working-capital needs before recovery from customers.
- Centuri execution and concentration: Customer concentration, union labor availability and costs, subcontractor reliance, weather, and losses on fixed-price or capped contracts could adversely affect results.
- Other risks: Pipeline accidents, cybersecurity incidents, environmental and climate regulation, interest-rate exposure, credit-rating changes, and pension assumptions may affect operations or financing costs. The parent holding company depends on subsidiary distributions to meet obligations and pay dividends.
- Legal proceedings: The company stated that pending matters were not expected, individually or in aggregate, to have a material adverse impact on financial position or results of operations.
Important facts for investors to verify
- Review the incorporated 2020 Annual Report for complete consolidated and subsidiary revenue, earnings, cash-flow, margin, debt, liquidity, and segment results, plus year-over-year comparisons.
- Check the status and financial effect of the California rate case and the realized impact of Arizona and Nevada rate changes.
- Verify COVID-19-related regulatory deferrals, customer arrears, collection trends, and any resulting cost recovery.
- Assess Centuri’s backlog conversion, customer concentration, contract profitability, and exposure to utility capital-budget changes.
- Confirm total debt, facility availability and borrowings, upcoming maturities, covenant headroom, and sensitivity to interest rates.
- Evaluate the sustainability of dividend growth against earnings, capital spending, and external financing requirements.
