Southwest Gas Holdings, Inc. - Q2 2026 Filing Summary
Business Context and Reporting Period
This Form 10-Q covers the quarterly period ended June 30, 2026, for Southwest Gas Holdings, Inc. (Holdings) and its wholly-owned subsidiary, Southwest Gas Corporation (Southwest Gas). Following the deconsolidation of its Utility Infrastructure Services segment (Centuri) in August 2025, the Company now operates solely as a regulated natural gas distributor serving customers in Arizona, Nevada, and California. The filing includes restated prior-year figures to reflect discontinued operations and corrections to deferred income tax liabilities.
Key Financial Metrics (Six Months Ended June 30, 2026)
- Revenue: Regulated operations revenues totaled $943.3 million, a decrease from $1.14 billion in the prior year period, primarily due to lower net cost of gas sold passed through to customers.
- Profitability: Net income attributable to Holdings was $180.5 million ($2.49 per diluted share), compared to $73.7 million ($1.02 per share) in the prior year. Operating income was $303.7 million.
- Operating Margin: A non-GAAP measure defined as revenues less net cost of gas sold, totaled $796.7 million, an increase of $40.7 million year-over-year driven by rate increases and customer growth.
- Cash Flow: Net cash provided by operating activities was $308.2 million. Net cash used in investing activities was $521.6 million, primarily for capital expenditures.
- Liquidity: Cash and cash equivalents stood at $270.5 million at quarter-end. Total available liquidity is approximately $1.0 billion, supported by $400 million in revolving credit facilities (Holdings and Southwest Gas combined) with no outstanding borrowings.
- Debt: Long-term debt (less current maturities) was $3.41 billion. Current maturities of long-term debt were $100.0 million.
Material Changes vs. Prior Period
- Discontinued Operations: The prior year period included results from Centuri, which are now classified as discontinued operations. The current period reflects only the Natural Gas Distribution segment.
- Restatements: Prior year financial statements were restated to correct errors in estimated deferred income tax liabilities related to state apportionment rates following the Centuri deconsolidation. This adjustment increased income tax expense and reduced net income for the prior year periods.
- Rate Increases: Operating margin increased significantly due to the implementation of new rates in California (All-Party Settlement) and Arizona (SIM surcharge), offsetting lower gas cost pass-throughs.
- Capital Expenditures: Capital expenditures increased to $529.1 million for the six months ended June 30, 2026, compared to $362.5 million in the prior year, driven by infrastructure replacement and the Great Basin 2028 expansion project.
Guidance, Outlook, and Risks
- Regulatory Proceedings:
- California: CPUC approved a $39.5 million revenue increase effective July 1, 2026. Final cost-of-capital decisions are expected in Q3 2026.
- Arizona: Filed a general rate case seeking ~$101 million in incremental annual revenues; new rates expected by April 2027. Approved the first System Integrity Mechanism (SIM) surcharge.
- Nevada: Filed a general rate case seeking ~$74 million in incremental annual revenues; new rates expected in October 2026. Approved the first triennial resource plan.
- Great Basin Expansion: Precedent agreements executed for ~1 Bcf/d capacity for the 2028 expansion project. Estimated capital investment is ~$1.7 billion, potentially increasing by $0.6 billion based on additional demand.
- Dividends: Quarterly dividend increased to $0.645 per share, effective June 2026.
- Risks: Key risks include regulatory lag, variability in natural gas prices impacting liquidity (currently an over-collection of $286.8 million in PGA balances), and the timing of rate relief. Management has remediated a previously identified material weakness in internal controls over state income tax apportionment.
Investor Verification Checklist
- Verify the final CPUC decision on cost of capital for California, expected in Q3 2026, and its impact on future earnings.
- Monitor the status of the Arizona and Nevada general rate cases filed in early 2026 for approval timing and magnitude.
- Track the execution of the Great Basin 2028 expansion project, including FERC approval and potential cost overruns.
- Review the management of the $286.8 million Purchased Gas Adjustment (PGA) over-collection liability and its impact on future cash flows.
- Confirm the effectiveness of the new internal controls implemented to address the previously reported material weakness in tax accounting.
