Southwest Gas Holdings, Inc. filings document the regulatory, financial, governance, and capital-structure disclosures of a NYSE-listed natural gas utility holding company. Current reports furnish operating results, dividend actions, rate-case developments, Great Basin project disclosures, and material corporate events involving Southwest Gas Holdings and Southwest Gas Corporation.
Proxy materials cover board composition, director elections, executive compensation, shareholder voting matters, and governance arrangements. The filing record also includes executive and director transition disclosures, termination of a cooperation agreement with the Icahn Group, common stock registration details, and accounting matters related to deferred income tax liabilities and financial-statement reliance.
Southwest Gas Holdings is restating certain 2025 quarterly results after finding errors in how it estimated deferred state income tax liabilities following Centuri stock sales and tax deconsolidation. The Audit Committee determined that the unaudited condensed consolidated financial statements for the quarters and year-to-date periods ended June 30 and September 30, 2025 should no longer be relied upon.
The errors understated income tax expense and net deferred income tax liabilities by about $27 million for the June 30, 2025 periods and an additional $8 million for the September 30, 2025 periods, reducing GAAP net income and increasing reported losses. Revenue, operating margin and cash flows for these periods are unchanged, and the company reaffirms its 2025 net income guidance and 2025–2029 CAGR targets.
Restated interim figures will be included in the 2025 Form 10‑K and future filings, and prior earnings releases and presentations covering these periods should not be relied upon. Southwest Gas expects to report ineffective disclosure controls and procedures and a material weakness in internal control over financial reporting for the affected 2025 interim periods and the year ended December 31, 2025.
