Background, Organization, and Summary of Significant Accounting Policies | Note 1 – Background, Organization, and Summary of Significant Accounting Policies Nature of Operations. Southwest Gas Holdings, Inc. (together with its subsidiaries, the “Company”) is a holding company, owning all of the shares of common stock of Southwest Gas Corporation (“Southwest” or the “natural gas distribution” segment), and through the first quarter of 2024, all of the shares of common stock of Centuri Group, Inc. (“utility infrastructure services” segment), and until February 14, 2023, all of the shares of common stock of MountainWest Pipelines Holding Company (“MountainWest” or the “pipeline and storage” segment). References throughout this document in reference to “Centuri” relate to Centuri Group, Inc., for earlier periods or more recently, to Centuri Holdings, Inc. In December 2022, the Company announced that its Board of Directors (the “Board”) unanimously determined to take strategic actions to simplify the Company’s portfolio of businesses. These actions included entering into a definitive agreement to sell 100% of MountainWest to Williams Partners Operating LLC (“Williams”) for $1.5 billion in total enterprise value, subject to certain adjustments (collectively, the “MountainWest sale”). The MountainWest sale closed on February 14, 2023. As part of this simplification strategy, the Company previously communicated that it would pursue a separation of Centuri. In April 2024, the Company announced the completion of an initial public offering (“IPO”) of Centuri Holdings, Inc. common stock, with the issuance of 14,260,000 shares ($0.01 par value) at $21.00 per share, along with a private placement of 2,591,929 shares at the same public offering price with Icahn Partners LP and Icahn Partners Master Fund LP, investment entities associated with Carl C. Icahn. The Company owns approximately 81% of Centuri following these events. Through the first quarter of 2024 and leading up to the IPO, Centuri continued to be wholly owned by Southwest Gas Holdings, Inc. Centuri continues to be consolidated as part of these financial statements, and will continue to be consolidated until such time as the conditions for consolidation are no longer met. Centuri now makes separate filings with the Securities and Exchange Commission (the “SEC”) as a public company. The Company’s common stock continues to trade under the ticker symbol “SWX,” while Centuri’s common stock trades under the ticker symbol “CTRI.” As part of the IPO and related undertakings, and to ultimately facilitate a full separation of Centuri over periods ahead, multiple agreements were executed between the Company and Centuri, including a Separation Agreement, a Tax Matters Agreement, and a Registration Rights Agreement. Centuri’s new Board of Directors includes certain overlapping board members with the Company, including Andrew W. Evans, Anne L. Mariucci, and Karen S. Haller (the Company’s Chief Executive Officer). See also Note 8 - Dispositions . Southwest is engaged in the business of purchasing, distributing, and transporting natural gas for customers in portions of Arizona, Nevada, and California. Public utility rates, practices, facilities, and service territories of Southwest are subject to regulatory oversight. The timing and amount of rate relief can materially impact results of operations. Natural gas purchases and the timing of related recoveries can materially impact liquidity, highlighted by the significant amount of cash existing as of the end of the first quarter of 2024, reflective of the collection of gas cost under purchased gas cost mechanisms as a component of customer bills. While mechanisms exist in all states in which Southwest operates, which effectively and primarily decouple authorized operating cost recovery and profitability from the volume of natural gas sold, thereby also incentivizing energy conservation, results for the natural gas distribution segment are higher during winter periods due to the seasonality incorporated in its regulatory rate structures. Centuri is a strategic utility infrastructure services company dedicated to partnering with North America’s gas and electric providers to build and maintain the energy network that powers millions of homes across the United States (“U.S.”) and Canada. Centuri derives revenue primarily from installation, replacement, repair, and maintenance of energy networks. Centuri operates in the U.S., primarily as NPL, Neuco, Linetec, and Riggs Distler, and in Canada, primarily as NPL Canada. Utility infrastructure services activity is seasonal in many of Centuri’s operating areas. Peak periods are the summer and fall months in colder climate areas, such as the northeastern and midwestern U.S. and in Canada. In warmer climate areas, such as the southwestern and southeastern U.S., utility infrastructure services activity continues year round. Basis of Presentation. The condensed consolidated financial statements of Southwest Gas Holdings, Inc. and subsidiaries and Southwest (with its subsidiaries) included herein have been prepared pursuant to the rules and regulations of the SEC. The year-end 2023 condensed balance sheet data was derived from audited financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. No substantive change has occurred with regard to the Company’s business segments on the whole during the recently completed quarter. The preparation of the condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, as of the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. In the opinion of management, all adjustments, consisting of normal recurring items and estimates necessary for a fair statement of results for the interim periods, have been made. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto of Southwest and the Company included in our 2023 Annual Report on Form 10-K for the fiscal year ended December 31, 2023. In the first quarter of 2023, management identified a misstatement related to its accounting for the cost of gas sold at Southwest, thereby determining that Net cost of gas sold was overstated in 2021 and 2022 by $2.3 million and $5.7 million, respectively. Southwest made an adjustment in the first quarter of 2023 to reduce Net cost of gas sold and to increase its asset balance for Deferred purchased gas cost by $8 million. Also in the first quarter of 2023, the Company identified an approximately $21 million misstatement related to its initial estimation of the loss recorded upon reclassifying MountainWest as an asset held for sale during the year ended December 31, 2022. Consequently, the impairment loss for the year ended December 31, 2022 was understated by approximately $21 million, which was corrected in the first quarter of 2023. The Company (and Southwest, with respect to Net cost of gas sold) assessed, both quantitatively and qualitatively, the impact of these items on previously issued financial statements, concluding they were not material to any earlier period or to the period of correction. Other Property and Investments. Other property and investments on Southwest’s and the Company’s Condensed Consolidated Balance Sheets includes: (Thousands of dollars) March 31, 2024 December 31, 2023 Net cash surrender value of COLI policies $ 150,182 $ 146,546 Other property 6,080 6,112 Total Southwest Gas Corporation 156,262 152,658 Non-regulated property, equipment, and intangibles 1,750,380 1,752,094 Non-regulated accumulated provision for depreciation and amortization (691,872) (675,632) Other property and investments 38,091 37,220 Total Southwest Gas Holdings, Inc. $ 1,252,861 $ 1,266,340 Held for sale. In the first quarter of 2023, the Company and Southwest concluded certain assets associated with their previous corporate headquarters met the criteria to be classified as held for sale. As a result, the Company and Southwest reclassified approximately $27 million from Other property and investments to Current assets held for sale on their respective Condensed Consolidated Balance Sheets in the first quarter of 2023. In 2023, the Company and Southwest recorded an estimated loss of $5.2 million on the assets based upon an updated fair value less costs to sell. The sale was completed in January 2024. Cash and Cash Equivalents. Cash and cash equivalents of the Company include $407.4 million and $48.9 million of money market fund investments at March 31, 2024 and December 31, 2023, respectively. Of these amounts, $407.2 million and $38.6 million at March 31, 2024 and December 31, 2023, respectively , were held by Southwest. Refer to discussion above regarding recent collections under Southwest’s purchased gas adjustment mechanisms. Noncash investing activities include capital expenditures that were not yet paid, thereby remaining in accounts payable, amounts related to which declined by approximately $20.8 million and $9.6 million during the three months ended March 31, 2024, for the Company and Southwest, respectively; and declined approximately $37.3 million and $34.2 million during the three months ended March 31, 2023, for the Company and Southwest, respectively. The Company and Southwest expanded their presentation in the first quarter 2024 to show the Change in short-term portion of credit facility and Repayment of short-term debt as separate line items within their Condensed Consolidated Statements of Cash Flows. The comparable prior-year period has been updated to reflect this change. Prepaid and other current assets. Prepaid and other current assets for the Company and Southwest include, among other things, materials and operating supplies of $80.9 million at March 31, 2024 and $83.4 million at December 31, 2023 (carried at weighted average cost). Goodwill. Goodwill is assessed as of October 1 each year for impairment, or more frequently, if circumstances indicate an impairment to the carrying value of goodwill may have occurred. The Company’s reporting units for goodwill are its operating segments, which are also its reportable segments. Since December 31, 2023, management qualitatively assessed whether events during the first three months of 2024 indicated it was more likely than not that the fair value of our reporting units was less than their carrying value, which if the case, could be an indication of a goodwill impairment. Through management’s assessments, no impairment was deemed to have occurred in the continuing segments of the Company. Goodwill in the Natural Gas Distribution and Utility Infrastructure Services segments is included in the respective Condensed Consolidated Balance Sheets as follows: (Thousands of dollars) Natural Gas Utility Infrastructure Total Company December 31, 2023 $ 11,155 $ 778,574 $ 789,729 Foreign currency translation adjustment — (2,523) (2,523) March 31, 2024 $ 11,155 $ 776,051 $ 787,206 Other Current Liabilities . Management recognizes in its balance sheets various liabilities that are expected to be settled through future cash payment within the next twelve months, including amounts payable under regulatory mechanisms, customary accrued expenses for employee compensation and benefits, declared but unpaid dividends, and miscellaneous other accrued liabilities. Other current liabilities for the Company include $44.4 million of dividends declared as of both March 31, 2024 and December 31, 2023, respectively. Also included in the balance for the Company and Southwest was $120.3 million and $87.6 million in accrued purchased gas cost as of March 31, 2024 and December 31, 2023, respectively. Other Income (Deductions). The following table provides the composition of significant items included in Other income (deductions) in Southwest’s and the Company’s Condensed Consolidated Statements of Income: Three Months Ended March 31, (Thousands of dollars) 2024 2023 Southwest Gas Corporation: Change in COLI policies $ 3,600 $ 2,400 Interest income 9,776 12,471 Equity AFUDC 1,839 — Other components of net periodic benefit cost 4,131 4,959 Miscellaneous expense (1,246) (1,387) Southwest Gas Corporation - total other income (deductions) 18,100 18,443 Centuri, MountainWest, and Southwest Gas Holdings, Inc.: Foreign transaction gain (loss) 102 (690) Equity AFUDC — 82 Equity in earnings (loss) of unconsolidated investments (113) 360 Miscellaneous income and (expense) 43 (5) Corporate and administrative (11) 270 Southwest Gas Holdings, Inc. - total other income (deductions) $ 18,121 $ 18,460 Interest income primarily relates to Southwest’s regulatory asset balances, including its deferred purchased gas cost mechanisms, the combined balance of which ranged from $970 million as of March 31, 2023 to $199 million as of March 31, 2024. Refer also to Note 2 – Components of Net Periodic Benefit Cost . Redeemable Noncontrolling Interests . In connection with the acquisition of Linetec in November 2018, the previous owner initially retained a 20% equity interest in that entity, with redemption being subject to certain rights based on the passage of time or upon the occurrence of certain triggering events. Effective in 2022, the Company, through Centuri, had the right, but not the obligation, to purchase at fair value (subject to a floor) a portion of the interest held by the previous owner, and in incremental amounts each year thereafter. In March 2022, the parties agreed to a partial redemption, reducing the noncontrolling interest to 15%, and in March 2023, agreed to a partial 5% redemption (of the 15% then remaining). Then again in April 2023, Centuri paid $39.9 million to the previous owner, thereby reducing the balance continuing to be redeemable at that time to 10% under the terms of the original agreement. In March 2024, the parties entered into an agreement to redeem the remaining 10% equity interest for $92 million, which resulted in Centuri owning all of the equity interest in Linetec as of March 31, 2024. The Company paid the $92 million in April, in accordance with the agreement. The impact of this transaction has been excluded from the Company’s Condensed Consolidated Statement of Cash Flows for the first quarter of 2024 due to its noncash nature during the period. Separately, certain members of Riggs Distler management have a 1.41% interest in Drum, which is redeemable, subject to certain rights based on the passage of time or upon the occurrence of certain triggering events. A portion of the redeemable noncontrolling interest was funded through promissory notes made to noncontrolling interest holders bearing interest at the prime rate plus 2%. During the first quarter of 2024, Centuri forgave all outstanding promissory notes and unpaid interest owed from the Riggs Distler noncontrolling interest holders and in exchange obtained 0.47% portion of the equity interest in Drum that had been funded through these notes. This comprises most of the change noted below as redemption of Drum interests during the quarter. Additionally, during the first quarter of 2024, Centuri reached an agreement to purchase 0.13% of the noncontrolling interest in Drum for $0.8 million, the majority which was accrued in March 2024 and ultimately paid in April 2024. The impact of the accrued amount has been excluded from the Company’s Condensed Consolidated Statement of Cash Flows for the first quarter of 2024 due to the noncash nature in advance of the April 2024 payment. The remaining noncontrolling interest in Drum outstanding as of March 31, 2024 was 0.81%, with Centuri owning over 99% of Drum following these events. Significant changes in the value of the redeemable noncontrolling interests, above a floor determined at the establishment date, are recognized as they occur, and the carrying value is adjusted as necessary at each reporting date. The fair value is estimated using a market approach that utilizes certain financial metrics from guideline public companies of similar industry and operating characteristics. Valuation adjustments also impact retained earnings, as reflected in the Company’s Condensed Consolidated Statement of Equity, but do not impact net income. The following depicts changes to the balances of the redeemable noncontrolling interests: (Thousands of dollars): Linetec Drum Total Balance, December 31, 2023 $ 91,978 $ 12,689 $ 104,667 Net income (loss ) attributable to redeemable noncontrolling interests (193) 18 (175) Redemption value adjustments 194 — 194 Redemption of equity interest from noncontrolling party (91,979) (5,046) (97,025) Balance, March 31, 2024 $ — $ 7,661 $ 7,661 Earnings Per Share. Basic earnings per share (“EPS”) in each period of this report were calculated by dividing net income attributable to Southwest Gas Holdings, Inc. by the weighted-average number of shares during those periods. Diluted EPS includes additional weighted-average common stock equivalents (performance shares and restricted stock units). Unless otherwise noted, the term “Earnings Per Share” refers to Basic EPS. A reconciliation of the denominator used in Basic and Diluted EPS calculations is shown in the following table: Three Months Ended March 31, (In thousands) 2024 2023 Weighted average basic shares 71,728 68,265 Effect of dilutive securities: Restricted stock units (1) 154 154 Weighted average diluted shares 71,882 68,419 (1) The number of securities included 136,000 and 132,000 performance shares during the three months ended March 31, 2024 and March 31, 2023, the total of which was derived by assuming that target performance will be achieved during the relevant performance period. Income Taxes. The C ompany’s effective tax rate was 16.3% for the three months ended March 31, 2024, compared to 37.6% for the corresponding period in 2023. The effective rate decrease was primarily due to the MountainWest sale in 2023, which also included the impact of book versus tax basis differences related to the transaction (See Note 8 - Dispositions ). Southwest’s effective tax rate was 18.2% for the three months ended March 31, 2024, compared to 18.3% for the corresponding period in 2023. These amounts varied from the statutory rate primarily as the result of the amortization of excess deferred income taxes. In April 2023, the Internal Revenue Service issued Revenue Procedure 2023-15, which provides a safe harbor method of accounting that taxpayers may use to determine whether expenditures to repair, maintain, replace, or improve natural gas transmission and distribution property must be capitalized for tax purposes. The Company and Southwest are currently reviewing this revenue procedure to determine the potential impact on their financial position, results of operations, and cash flows. Recent Accounting Standards Updates. Recently issued accounting pronouncement that will be effective in 2024 and later periods: In November 2023, the Financial Accounting Standards Board (the “FASB”) issued ASU 2023-07 “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” The update, among other amendments, requires disclosure of significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit or loss, as well as an amount and description of the composition of other segment items to reconcile to segment profit or loss, and also requires the title and position of the entity’s CODM to be disclosed. The update additionally extends certain annual disclosures to interim periods.

Retirement Benefits [Abstract] | |
Components of Net Periodic Benefit Cost | Note 2 – Components of Net Periodic Benefit Cost Southwest has a noncontributory qualified retirement plan with defined benefits covering substantially all employees (those hired before 2022) and a separate unfunded supplemental retirement plan (“SERP”), which is limited to officers hired before 2022. Southwest also provides limited postretirement benefits other than pensions (“PBOP”) to its qualified retirees for health care, dental, and life insurance. The service cost component of net periodic benefit costs included in the table below is a component of an overhead loading process associated with the cost of labor. The overhead process ultimately results in allocation of service cost to the same accounts to which productive labor is charged. As a result, service costs become components of various accounts, primarily operations and maintenance expense, net regulated operations plant, and deferred charges and other assets for both the Company and Southwest. The other components of net periodic benefit cost are reflected in Other income (deductions) on the Condensed Consolidated Statements of Income of each entity. Variability in total net periodic benefit cost between periods, especially with regard to the Qualified Retirement Plan, is subject to changes in underlying actuarial assumptions between periods, notably the discount rate.

Revenue from Contract with Customer [Abstract] | |
Revenue | Note 3 – Revenue The following information about the Company’s revenues is presented by segment. Southwest encompasses the natural gas distribution segment and Centuri encompasses the utility infrastructure services segment. Natural Gas Distribution Segment : Southwest’s operating revenues included on the Condensed Consolidated Statements of Income of both the Company and Southwest include revenue from contracts with customers, which is shown below, disaggregated by customer type, in addition to other categories of revenue: Three Months Ended (Thousands of dollars) 2024 2023 Residential $ 784,237 $ 739,313 Small commercial 206,445 174,184 Large commercial 38,016 31,091 Industrial/other 20,823 21,114 Transportation 28,687 30,543 Revenue from contracts with customers 1,078,208 996,245 Alternative revenue program revenues (deferrals) (29,433) (86,204) Other revenues (1) 4,158 4,838 Total Regulated operations revenues $ 1,052,933 $ 914,879 (1) Amounts include late fees and other miscellaneous revenues, and may also include the impact of certain regulatory mechanisms. Utility Infrastructure Services Segment : During the fourth quarter of 2023, Utility infrastructure services segment management, in connection with Centuri’s planned separation, changed its service type revenue classification to align with changes in its organizational structure, and as a result, prior year “other” revenue has been recast into gas infrastructure services or electric power infrastructure services to reflect these changes, with no impact to revenue overall. The following tables display Centuri’s revenue, reflected as Utility infrastructure services revenues on the Condensed Consolidated Statements of Income of the Company, representing revenue from contracts with customers disaggregated by service and contract types: Three Months Ended (Thousands of dollars) 2024 2023* Service Types: Gas infrastructure services $ 261,226 $ 298,640 Electric power infrastructure services 260,466 342,275 Other 6,331 12,378 Total Utility infrastructure services revenues $ 528,023 $ 653,293 *The three months ended March 31, 2023 were previously presented as: Gas infrastructure services of $297,408, Electric power infrastructure services of $233,640, and Other of $122,245. Three Months Ended (Thousands of dollars) 2024 2023 Contract Types: Master services agreement $ 443,242 $ 547,606 Bid contract 84,781 105,687 Total Utility infrastructure services revenues $ 528,023 $ 653,293 Unit price contracts $ 307,849 $ 328,527 Fixed price contracts 110,282 166,915 Time and materials contracts 109,892 157,851 Total Utility infrastructure services revenues $ 528,023 $ 653,293 The following table provides information about contracts receivable and revenue earned on contracts in progress in excess of billings (contract assets), both of which are included within Accounts receivable, net of allowances, as well as amounts billed in excess of revenue earned on contracts (contract liabilities) at Centuri, which are included in Other current liabilities as of March 31, 2024 and December 31, 2023 on the Company’s Condensed Consolidated Balance Sheets: (Thousands of dollars) March 31, 2024 December 31, 2023 Contracts receivable, net $ 287,815 $ 347,454 Revenue earned on contracts in progress in excess of billings 257,830 269,808 Amounts billed in excess of revenue earned on contracts 13,648 43,694 Revenue earned on contracts in progress in excess of billings (contract assets) that are not expected to be recognized within a year from the financial statement date are not included in the table above, and were $16.5 million as of March 31, 2024, and $0.2 million as of December 31, 2023. These non-current balances were included in Deferred charges and other assets on the Company’s Condensed Consolidated Balance Sheets. These contract assets primarily relate to Centuri’s rights to consideration for work completed, but not billed and/or approved for billing at the rep orting date, and are transferred to contracts receivable when the rights become unconditional. The amounts billed in excess of revenue earned primarily relate to the adva nce consideration received from customers for which work has not yet been completed. The decrease in the contract liability balance from December 31, 2023 to March 31, 2024 of $30 million was due t o revenue recognized during the period, net of new payments received in advance of work performed. For contracts that have an original duration of one year or less, Centuri uses the practical expedient applicable to such contracts and does not consider/compute an interest component based on the time value of money. Furthermore, because of the short duration of these contracts, Centuri has not disclosed the transaction price for the remaining performance obligations as of the end of each reporting period or when the Company expects to recognize the revenue. As of March 31, 2024, Centuri h ad 53 fi xed price contracts with an original duration of more than one year. The aggregate amount of the transaction price allocated to the unsatisfied performance obligations of these contracts as of March 31, 2024 was $277 million. C enturi expects to recognize the remaining performance obligations over approximately the next two years ; however, the timing of that recognition is largely within the control of the customer, including when the necessary materials required to complete the work are provided by the customer. Utility infrastructure services contracts receivable consists of the following: (Thousands of dollars) March 31, 2024 December 31, 2023 Billed on completed contracts and contracts in progress $ 285,896 $ 348,021 Other receivables 1,989 1,945 Contracts receivable, gross 287,885 349,966 Allowance for doubtful accounts (70) (2,512) Contracts receivable, net $ 287,815 $ 347,454 |

Southwest designates $150 million of associated capacity as long-term debt and the remaining $250 million for working capital purposes. Interest rates for the credit facility are calculated at either the Secured Overnight Financing Rate (“SOFR”) or an “alternate base rate,” plus in each case an applicable margin that is determined based on Southwest’s senior unsecured debt rating. At March 31, 2024, the applicable margi n i s 1.125% for loans bearing interest with reference to SOFR and 0.125% for loans bearing interest with reference to the alternative base rate. At March 31, 2024, no borrowings were outstanding on the long-term portion (including under the commercial paper program), nor under the short-t erm portion of the facility. Centuri has a $1.545 billion secured revolving credit and term loan multi-currency facility. Amounts can be borrowed in either Canadian or U.S. dollars. The revolving credit facility matures on August 27, 2026 and the term loan facility matures on August 27, 2028 . Interest rates for the revolving credit facility and term loan facility are based on either a “base rate,” SOFR or the Canadian Dollar Offered Rate (“CDOR”), plus an applicable margin. The capacity of the line of credit portion of the facility is $400 million; related amounts borrowed and repaid are available to be re-borrowed. The term loan portion of the facility has a limit of $1.145 billion . The obligations under the credit agreement are secured by present and future ownership interests in substantially all direct and indirect subsidiaries of Centuri, substantially all of the tangible and intangible personal property of each borrower, certain of their direct and indirect subsidiaries, and all products, profits, and proceeds of the foregoing. Centuri’s assets securing the facility at March 31, 2024 totaled $2.4 billion . At March 31, 2024, $1.1 billion in borrowings were outstanding under Centuri’s combined secured revolving credit and term loan facility. On March 22, 2024, Centuri amended the financial covenants of its revolving credit facility to increase the maximum total net leverage ratio for the fiscal quarter ending March 31, 2024 to a ratio of 5.75 to 1.00, for the fiscal quarter ending June 30, 2024 to a ratio of 6.00 to 1.00, and for the fiscal quarter ending September 30, 2024 to a ratio of 5.75 to 1.00. In addition, this amendment increased the adjusted maximum total net leverage ratio financial covenants, which are applicable in the event that a “Qualified IPO” (as defined in the amendment) is consummated, for each of the fiscal quarters ending March 31, 2024, June 30, 2024, and September 30, 2024. The terms of the Centuri credit facility otherwise remain unchanged. Following the IPO and private placement, Centuri used approximately $316 million of proceeds to pay down $156 million of debt under the existing line of credit and $160 million of debt under the term loan portion of the facility, with the remainder intended for general corporate purposes. Short-Term Debt Southwest Gas Holdings, Inc. has a $300 million credit facility that is scheduled to expire in December 2026 and is primarily used for short-term financing needs. Interest rates for the credit facility are calculated at either SOFR or the “alternate base rate,” plus in each case an applicable margin. There was $94 million outstanding under this credit facility as of March 31, 2024. In April 2023, Southwest Gas Holdings, Inc. entered into a $550 million Term Loan Credit Agreement (the “Term Loan”) that matures in October 2024. Southwest Gas Holdings, Inc. utilized a majority of the proceeds to make an equity contribution to Southwest. |

Discontinued Operations and Disposal Groups [Abstract] | |
Dispositions | Note 8 - Dispositions Dispositions In December 2022, the Company announced that the Board unanimously determined to take strategic actions to simplify the Company’s portfolio of businesses. These actions included entering into a definitive agreement to sell 100% of MountainWest in an all-cash transaction to Williams for $1.5 billion in total enterprise value, subject to certain adjustments. The MountainWest sale was completed in February 2023. Additionally, the Company determined it would pursue a separation of Centuri to form a new independent publicly traded utility infrastructure services company. As discussed in Note 1 - Background, Organization, and Summary of Significant Accounting Policies , in April 2024, the Company and Centuri Holdings, Inc. announced the completion of an IPO of 12,400,000 shares of Centuri’s common stock at a price of $21.00 per share. Centuri granted the underwriters a 30-day option to purchase up to an additional 1,860,000 shares of its common stock, which was exercised. In addition, Centuri announced the concurrent private placement of an additional 2,591,929 shares at a price equal to the IPO price. Centuri’s common stock is listed on the New York Stock Exchange under the symbol “CTRI” and began trading on April 18, 2024. The net proceeds to Centuri from the IPO and the concurrent private placement, after deducting underwriting discounts and commissions of $18 million and estimated offering expenses, were approximately $329 million. Centuri used the proceeds to repay a portion (approximately $316 million) of outstanding indebtedness under its revolving credit and term loan facility, with the remainder for general corporate purposes. After completion of the IPO, and above undertakings, the Company continues to own approximately 81.0% of all ownership interests in Centuri. The Company intends to further reduce its ownership in future periods through sales of its remaining Centuri shares into the market, a distribution of Centuri shares to Company stockholders, or an exchange of Centuri shares for Southwest Gas Holdings, Inc. shares, or a combination thereof. The Company entered into several agreements with Centuri Holdings, Inc. in connection with the IPO and the planned separation, providing a framework for the relationship between the Company and Centuri after the IPO. |

Nature of Operations | Nature of Operations. Southwest Gas Holdings, Inc. (together with its subsidiaries, the “Company”) is a holding company, owning all of the shares of common stock of Southwest Gas Corporation (“Southwest” or the “natural gas distribution” segment), and through the first quarter of 2024, all of the shares of common stock of Centuri Group, Inc. (“utility infrastructure services” segment), and until February 14, 2023, all of the shares of common stock of MountainWest Pipelines Holding Company (“MountainWest” or the “pipeline and storage” segment). References throughout this document in reference to “Centuri” relate to Centuri Group, Inc., for earlier periods or more recently, to Centuri Holdings, Inc. Southwest is engaged in the business of purchasing, distributing, and transporting natural gas for customers in portions of Arizona, Nevada, and California. Public utility rates, practices, facilities, and service territories of Southwest are subject to regulatory oversight. The timing and amount of rate relief can materially impact results of operations. Natural gas purchases and the timing of related recoveries can materially impact liquidity, highlighted by the significant amount of cash existing as of the end of the first quarter of 2024, reflective of the collection of gas cost under purchased gas cost mechanisms as a component of customer bills. While mechanisms exist in all states in which Southwest operates, which effectively and primarily decouple authorized operating cost recovery and profitability from the volume of natural gas sold, thereby also incentivizing energy conservation, results for the natural gas distribution segment are higher during winter periods due to the seasonality incorporated in its regulatory rate structures. |

The condensed consolidated financial statements of Southwest Gas Holdings, Inc. and subsidiaries and Southwest (with its subsidiaries) included herein have been prepared pursuant to the rules and regulations of the SEC. The year-end 2023 condensed balance sheet data was derived from audited financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. No substantive change has occurred with regard to the Company’s business segments on the whole during the recently completed quarter. The preparation of the condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, as of the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. In the opinion of management, all adjustments, consisting of normal recurring items and estimates necessary for a fair statement of results for the interim periods, have been made. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto of Southwest and the Company included in our 2023 Annual Report on Form 10-K for the fiscal year ended December 31, 2023. |

Cash and Cash Equivalents | Cash and Cash Equivalents. Cash and cash equivalents of the Company include $407.4 million and $48.9 million of money market fund investments at March 31, 2024 and December 31, 2023, respectively. Of these amounts, $407.2 million and $38.6 million at March 31, 2024 and December 31, 2023, respectively , were held by Southwest. Refer to discussion above regarding recent collections under Southwest’s purchased gas adjustment mechanisms. Noncash investing activities include capital expenditures that were not yet paid, thereby remaining in accounts payable, amounts related to which declined by approximately $20.8 million and $9.6 million during the three months ended March 31, 2024, for the Company and Southwest, respectively; and declined approximately $37.3 million and $34.2 million during the three months ended March 31, 2023, for the Company and Southwest, respectively. |
Prepaid and other current assets | Prepaid and other current assets. Prepaid and other current assets for the Company and Southwest include, among other things, materials and operating supplies of $80.9 million at March 31, 2024 and $83.4 million at December 31, 2023 (carried at weighted average cost). |
Goodwill | Goodwill. |
Other Current Liabilities | Other Current Liabilities |
Redeemable Noncontrolling Interests | Significant changes in the value of the redeemable noncontrolling interests, above a floor determined at the establishment date, are recognized as they occur, and the carrying value is adjusted as necessary at each reporting date. The fair value is estimated using a market approach that utilizes certain financial metrics from guideline public companies of similar industry and operating characteristics. Valuation adjustments also impact retained earnings, as reflected in the Company’s Condensed Consolidated Statement of Equity, but do not impact net income. |
Earnings Per Share | Earnings Per Share. |
Income Taxes | Income Taxes. The C ompany’s effective tax rate was 16.3% for the three months ended March 31, 2024, compared to 37.6% for the corresponding period in 2023. The effective rate decrease was primarily due to the MountainWest sale in 2023, which also included the impact of book versus tax basis differences related to the transaction (See Note 8 - Dispositions ). Southwest’s effective tax rate was 18.2% for the three months ended March 31, 2024, compared to 18.3% for the corresponding period in 2023. These amounts varied from the statutory rate primarily as the result of the amortization of excess deferred income taxes. In April 2023, the Internal Revenue Service issued Revenue Procedure 2023-15, which provides a safe harbor method of accounting that taxpayers may use to determine whether expenditures to repair, maintain, replace, or improve natural gas transmission and distribution property must be capitalized for tax purposes. The Company and Southwest are currently reviewing this revenue procedure to determine the potential impact on their financial position, results of operations, and cash flows. |
Recent Accounting Standards Updates | Recent Accounting Standards Updates. Recently issued accounting pronouncement that will be effective in 2024 and later periods: In November 2023, the Financial Accounting Standards Board (the “FASB”) issued ASU 2023-07 “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” The update, among other amendments, requires disclosure of significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit or loss, as well as an amount and description of the composition of other segment items to reconcile to segment profit or loss, and also requires the title and position of the entity’s CODM to be disclosed. The update additionally extends certain annual disclosures to interim periods. The provisions of the update are effective for fiscal years beginning after December 15, 2023 and interim periods within the fiscal years beginning after December 15, 2024. Early adoption is permitted. Management is evaluating the impacts this update might have on the Company’s and Southwest’s disclosures. Recently issued accounting pronouncement that will be effective after 2024: In December 2023, the FASB issued ASU 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The update, among other amendments, provides for enhanced income tax information primarily through changes in the rate reconciliation and income taxes paid. The update is effective for annual periods beginning after December 15, 2024; early adoption is permitted. Management is evaluating the impacts this update might have on the Company’s and Southwest’s disclosures. |

Retirement Benefits [Abstract] | |
Schedule of Net Periodic Benefit Costs | The service cost component of net periodic benefit costs included in the table below is a component of an overhead loading process associated with the cost of labor. The overhead process ultimately results in allocation of service cost to the same accounts to which productive labor is charged. As a result, service costs become components of various accounts, primarily operations and maintenance expense, net regulated operations plant, and deferred charges and other assets for both the Company and Southwest. The other components of net periodic benefit cost are reflected in Other income (deductions) on the Condensed Consolidated Statements of Income of each entity. Variability in total net periodic benefit cost between periods, especially with regard to the Qualified Retirement Plan, is subject to changes in underlying actuarial assumptions between periods, notably the discount rate.
