Southwest Gas Raises Quarterly Dividend 4.0% to $0.645

Southwest Gas Holdings raised its quarterly dividend 4.0% to $0.645 a share from $0.62. The shares traded ex-dividend on May 15, 2026, and the new rate represents an annual dividend of $2.58 a share.

Why the dividend changed

Southwest Gas announced the increase with its full-year 2025 results, when the regulated utility reported improved earnings, stronger credit measures and upgrades of the holding company and utility credit ratings to BBB+. The board did not identify one financial measure as the trigger for the increase. Its stated dividend policy requires directors to weigh projected capital needs, liquidity, financial condition, the competitiveness of the yield, economic conditions, potential equity dilution and effects on credit ratings.

The balance-sheet context changed materially before the increase. Southwest Gas completed the disposition of Centuri, classified that business as discontinued operations and repaid a $550.0 million term loan during 2025. The transaction did not mechanically require a dividend change, and the company did not say it directly caused the increase. It did, however, reduce corporate debt and leave Southwest Gas more focused on regulated natural-gas infrastructure. Southwest Gas second-quarter 2026 filing

Operating investment remains substantial. Southwest Gas reaffirmed 2026 earnings guidance and continued funding infrastructure modernization, rate-base growth and the Great Basin expansion. Its latest results showed nearly $1.0 billion of available liquidity at June 30, 2026. Management also reported progress in rate proceedings across Arizona, California and Nevada, which are central to recovering infrastructure costs through customer rates.

Dividend track record

The increase extends Southwest Gas’s dividend-growth streak to 33 consecutive years. Its last annual cut was in 1992. The five-year dividend-growth rate is 1.7% annual growth, indicating that the record has been built through measured increases rather than rapid expansion.

Annual payments rose from $2.26 a share in 2020 to $2.36 in 2021, an increase of 4.4%, and to $2.46 in 2022, an increase of 4.3%. The total reached $2.48 in 2023 after rising 1.0%, then remained unchanged at $2.48 in both 2024 and 2025. That pattern shows a slowdown and two-year pause before the latest increase.

The payment record also shows how the new rate took effect. Southwest Gas paid $0.62 on shares with ex-dividend dates of November 17, 2025, and February 17, 2026. The amount then increased to $0.645 for the May 15, 2026, and August 17, 2026, ex-dividend dates. The sequence confirms a quarterly dividend that resumed growth after the flat annual totals in 2024 and 2025.

Is the dividend covered?

The dividend consumes 64% of earnings. That leaves earnings above the distribution while retaining a portion for operations, debt service and the company’s capital program. The retained margin is relevant because regulated gas utilities require sustained spending on pipeline replacement, system reliability and customer growth.

SmarterDividends rates the dividend A, with a safety score of 90. That falls within the very safe range of 80-100 and indicates strong protection against a reduction based on the measured factors. The grade does not eliminate the board’s discretion or the financing demands associated with Southwest Gas’s investment program.

Yield and valuation

The forward yield is 3.13%, below the Utilities sector median forward yield of 4.36%. The dividend therefore provides less current income than the sector midpoint, even after the increase. At the annual rate, 100 shares produce $258.00 of dividend income.

SmarterDividends estimates fair value at $155.74 and classifies the shares as undervalued, with 81% upside to that estimate. The estimate is a valuation measure, not a price target or forecast, and it is separate from the dividend’s earnings coverage and safety grade.

What to watch

The next quarterly results will provide an update on whether regulated earnings, liquidity and rate-case outcomes continue to support both the dividend and the capital program. Southwest Gas reaffirmed its full-year 2026 guidance in its second-quarter release, while noting that its longer-term guidance had not yet been updated for the higher estimated cost of the Great Basin project.

Great Basin is the main development to monitor. The company said binding commitments for the 2028 expansion had increased and that it was preparing a federal certificate application for later in 2026. Management plans to incorporate revised project assumptions into its annual five-year planning refresh. Investors can also track final regulatory outcomes and cost recovery in Southwest Gas’s three state service territories, because those decisions affect the cash retained after infrastructure spending.
