Detailed Narrative
California Regulatory Update
The final decision on the California general rate case has been delayed, but a memorandum account ensures the full-year benefit to earnings as if new rates were effective January 1. A draft decision approving the proposed settlement, representing approximately $39 million or nearly 90% of the requested revenue increase (excluding cost of capital), is on the CPUC's May 14 agenda. The cost of capital issues, which were the unsettled portion, will be addressed in a separate decision.
Arizona Regulatory Progress
Southwest Gas filed a general rate case in Arizona, requesting a $101 million revenue increase. This request is supported by a proposed rate base of approximately $3.9 billion, reflecting $900 million in incremental investments since the last rate case. The filing also included a request for a formula rate mechanism, expected to be implemented approximately 12 months after new rates are effective, designed to mitigate regulatory lag and align rates with service costs.
Nevada Regulatory Developments
A general rate case was filed in Nevada, seeking a $71 million revenue increase, anchored by a proposed rate base of approximately $2.4 billion, which includes $600 million of incremental investments. Under the statutory 210-day timeline, intervenor testimony is expected in Q3, with a final decision in October and new rates effective in Q4. Concurrently, the rule-making process for alternative ratemaking under SB 417 is advancing, with potential to enhance regulatory mechanisms and reduce lag.
Great Basin Expansion Project Momentum
The 2028 Great Basin expansion project remains on schedule across engineering, regulatory, and commercial milestones. A recent open season for 0.3 Bcf/d of available capacity was significantly oversubscribed, receiving bids totaling 2.5 Bcf/d, nearly eight times the available design capacity. This strong interest included demand for service ranging from 2028 to 2035. The company is now focused on converting this interest into binding precedent agreements.
Capital Investment and Rate Base Growth
Southwest Gas plans to invest approximately $1.25 billion in 2026 and $6.3 billion over the next five years, with a focus on safety, reliability, and system growth, including the Great Basin expansion project. This substantial capital program, nearly equal to the year-end 2025 rate base of $6.7 billion, is expected to support a rate base CAGR of 9.5% to 11.5% through 2030, driving consistent earnings growth.
Financial Strength and Liquidity
The company ended the quarter with approximately $3.2 billion of net debt and maintains strong investment-grade credit ratings. Following the payoff of all Holdco debt last summer, the company has significant liquidity and does not anticipate needing equity issuances in 2026. Operating cash flow, cash from holdings, and a planned bond issuance are expected to fund the 2026 capital program and a modest bond maturity.
