Why Everyone Is Watching Southwest Gas Holdings (SWX) Today

Southwest Gas Holdings (SWX) just released third quarter 2026 results, giving investors fresh numbers on sales, profit and earnings per share from its regulated natural gas operations across Arizona, Nevada and California.

The fresh earnings release lands after a bumpy few sessions for Southwest Gas Holdings, with the share price slipping around 2% over the past day and week. A roughly 9% one-month share price gain and about a 13% year-to-date share price return still point to improving momentum. Over a longer stretch, total shareholder return of about 18% over one year and more than 70% over three years suggests investors have been steadily rewarding the regulated utility story.

Most Popular Narrative: 10% Undervalued

On the most followed narrative, Southwest Gas Holdings screens about 10% below an estimated fair value of $100.63, compared with the latest close at $90.49.

Accelerated infrastructure investment opportunities are now anchored by a larger US$2.3b capital plan for the Great Basin 2028 Expansion Project and a broader US$6.3b 5 year utility capital program. These are expected to expand regulated rate base and in turn support higher future regulated revenue and earnings.
