SOUTHWEST GAS HOLDINGS, INC.						Form 10-Q
SOUTHWEST GAS CORPORATION						September 30, ~~2022~~2023

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), all of the shares of common stock of Centuri Group, Inc. (“Centuri,” or the “utility infrastructure services” segment), and until February 14, 2023, all of the shares of common stock of MountainWest Pipelines Holding Company (“~~MountainWest,”~~MountainWest” or the “pipeline and storage” segment).

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 and has continued to undertake significant efforts toward a near-term separation, including submitting a confidential draft registration statement on Form S-1 to the U.S. Securities and Exchange Commission (the “SEC”). See Note 8 - Dispositions for more information.

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. Results for the natural gas distribution segment are higher during winter periods due to the seasonality incorporated in its regulatory rate structures.

The Company completed the acquisition of Dominion Energy Questar Pipeline, LLC and related entities (“Questar Pipelines”) in December 2021 and formed MountainWest, which owns all of the membership interests in Questar Pipelines. In April 2022, the Company completed a general rebranding of the Questar Pipelines entities under the MountainWest name. The acquired operations further diversify the Company’s business in the midstream sector, with an expansion of interstate natural gas pipelines and underground storage services, primarily composed of regulated operations under the jurisdiction of the Federal Energy Regulatory Commission (the “FERC”), thereby expanding natural gas transportation services into Utah, Wyoming, and Colorado. See ~~Note 8 - Business Acquisitions~~ ~~for more information.~~

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.

~~Centuri completed the acquisition of Drum Parent LLC (“Drum”), including Drum’s most significant operating subsidiary, Riggs Distler,~~ ~~in August 2021, thereby expanding Centuri’s electric infrastructure services footprint in the northeast and mid-Atlantic regions of the U.S. See~~ ~~Note 8 - Business Acquisitions~~ ~~for more information.~~

~~In March 2022, the Company announced that its Board of Directors (the “Board”) had determined to separate Centuri from the Company and authorized management to complete the separation within~~ ~~nine~~ to twelve months. Initially it was contemplated that the Centuri separation would take the form of a spin-off. Then, in April 2022, as a result of interest in the Company well in excess of an earlier tender offer to other shareholders by an activist stockholder (affiliates of Carl C. Icahn), the Board authorized the review of a full range of strategic alternatives to maximize stockholder value. As part of this process, a strategic transactions committee of the Board (the “Strategic Transactions Committee”), consisting entirely of independent directors, began evaluating a sale of the Company, as well as a range of alternatives, including, but not limited to, a separate sale of its business units and/or pursuing the spin-off of Centuri (collectively, the “Strategic Review”). On August 3, 2022, the Company announced that the Board had unanimously determined that the best path forward to maximize value for all stockholders is to (i) focus on its strategic plan while concluding the strategic review process for Southwest Gas Holdings, Inc. and Southwest Gas Corporation; (ii) continue to review strategic alternatives for MountainWest; and (iii) continue to review strategic alternatives for Centuri, including a sale or spin-off of Centuri, among others.

On May 6, 2022, the Company entered into a Cooperation Agreement (the “Cooperation Agreement”) with Carl C. Icahn and the persons and entities referenced therein (collectively, the “Icahn Group”). In accordance with the Cooperation Agreement, among other things, John P. Hester, then President and Chief Executive Officer of the Company and Southwest, retired from his positions with the Company and Southwest and resigned from the Board. Karen S. Haller, the Company’s former Executive Vice President/Chief Legal and Administrative Officer, was appointed President and Chief Executive Officer of the Company and Chief Executive Officer of Southwest, and was appointed as a member of the Board effective immediately following the completion of the Company’s 2022 annual meeting of stockholders (the “2022 Annual Meeting”). Justin L. Brown, formerly Southwest’s Senior Vice President/General Counsel, was appointed as President of Southwest.

In addition, pursuant to the Cooperation Agreement, the Company agreed to appoint three new directors, Andrew W. Evans, H. Russell Frisby, Jr., and Henry P. Linginfelter (collectively, the “Initial Icahn Designees”), to the Board, which became effective immediately following the 2022 Annual Meeting. Also pursuant to the Cooperation Agreement, on May 27, 2022, the Icahn group informed the Company that it would cause Mr. Frisby to resign from the Board and requested that Andrew J. Teno be appointed to the Board to fill the vacancy created by Mr. Frisby’s resignation. As a result, on May 27, Mr. Frisby resigned from


			13


~~SOUTHWEST GAS HOLDINGS, INC.~~						~~Form 10-Q~~
~~SOUTHWEST GAS CORPORATION~~						~~September 30, 2022~~

the Board, effective immediately, and the Board appointed Mr. Teno to fill the vacancy created by Mr. Frisby’s resignation, effective immediately. The Icahn Group’s ability to designate directors to the Board is subject to certain ownership thresholds. Consistent with the terms of the Cooperation Agreement and pursuant to the terms of that certain Letter Agreement, dated as of August 3, 2022 (the “Letter Agreement” and together with the Cooperation Agreement, the “Initial Cooperation Agreement”), by and between the Company and the Icahn Group, the Company agreed to extend the date by which the Icahn Group was permitted to appoint a director other than Mr. Frisby to replace Mr. Cárdenas on the Board. On August 9, 2022, in accordance with the terms of the Initial Cooperation Agreement, Ruby Sharma was appointed to the Board to replace Mr. Cárdenas.

The Initial Cooperation Agreement required the Board to expand the Strategic Transactions Committee from three directors to six directors, comprised of the existing members of the Strategic Transactions Committee in addition to the three Initial Icahn Designees. Also, as the Icahn Group has the ability to designate at least three members of the Board, such individuals are to be included on the Strategic Transactions Committee. If the Icahn Group may only designate two members of the Board, then both would serve on the Strategic Transactions Committee.

On May 9, 2022, the Company also entered into Amendment No. 1 to the Rights Agreement dated October 10, 2021 (the “Original Rights Agreement” and as amended, the “Amended Rights Agreement”), to increase the triggering percentage from 10% to 24.9% pursuant to the terms of the Initial Cooperation Agreement and permit the subsequent consummation of the Offer. The Amended Rights Agreement expired on October 9, 2022. See details in the Company’s and Southwest’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021 (the “2021 Form 10-K”) regarding the Original Rights Agreement, as well as ~~Note 4 – Common Stock~~ ~~in this current report on Form 10-Q.~~

An earlier civil suit (initiated in November 2021) by Icahn entities against the Company and certain directors and officers of the Company was subject to a stipulation of dismissal as part of the Initial Cooperation Agreement. The Initial Cooperation Agreement also provided for the reimbursement by the Company of certain out-of-pocket third-party expenses, including certain legal fees, incurred by the Icahn Group.

On October 24, 2022, the Company and the Icahn Group entered into an Amended and Restated Cooperation Agreement (the “Amended Cooperation Agreement”), which amended, restated, superseded, and replaced in its entirety the Initial Cooperation Agreement. Please see ~~Note 9 - Subsequent Events~~ ~~for additional information about the Amended Cooperation Agreement.~~

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 ~~Securities and Exchange Commission (the “SEC”).~~SEC. The year-end ~~2021~~2022 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, ~~and~~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 ~~depiction~~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 included in the ~~2021~~2022 Annual Report to Stockholders, which is incorporated by reference into ~~the 2021 Form 10-K.~~

~~Other Property and Investments.~~ ~~Other property and investments on~~ Southwest’s and the Company’s ~~Condensed Consolidated Balance Sheets includes:~~2022 Annual Report on Form 10-K.

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 prior period or the current period financial statements.

Cash and Cash Equivalents. Cash and cash equivalents of the Company include $5667.7 million and ~~$20~~$30 million of money market fund investments at September 30, ~~2022~~2023 and December 31, ~~2021,~~2022, respectively. The money market fund investments for Southwest were ~~insignificant~~$66 million at ~~both balance sheet dates. These investments fall within Level 2 of the fair value hierarchy, due to the asset valuation methods used by money market funds.~~September 30, 2023 and $17.6 million at December 31, 2022, respectively.

Noncash investing activities ~~for the Company and Southwest~~ include capital expenditures that were not yet paid, thereby remaining in accounts payable, the amounts related to which declined by approximately ~~$4.8~~$39.6 million and ~~$11.6~~$35.2 million during the nine months ended September 30, ~~2022,~~2023, for the Company and Southwest, respectively, and ~~increased $16.1~~decreased $10.5 million and ~~$9.4~~$2.9 million for each of these entities during the twelve months ended September 30, ~~2022, respectively.~~2023.

~~Accounts Receivable, net~~The Other change in short-term debt as presented on the Company’s and Southwest’s Condensed Consolidated Statements of ~~allowances.~~ Following an earlier moratorium on account disconnections amidst the COVID-19 environment, account collection efforts resumed in 2021 in all jurisdictions in which Southwest operates. Ultimately, some accounts may not be collected,Cash Flows is comprised of repayments of short-term debt and ~~if collection is unsuccessful, such accounts are written off. Estimates as to collectibility are made on an ongoing basis. However,~~ Southwest continues to actively work with customers experiencing financial hardship by means of flexible payment options and partnering with assistance agencies. The cost of gas included in customer rates also influences account balances at each reporting date.

~~Deferred Purchased Gas Costs.~~ ~~The various regulatory commissions have established procedures to enable the rate-regulated companies to adjust billing rates for~~ changes in the current portion of the credit facility.

Deferred purchased gas costs. In July 2023, the Arizona Corporation Commission approved an increase in the gas cost balancing account (“GCBA”) rate, over a two-year period, as an enhancement to the existing gas cost recovery mechanism, given the $358 million Arizona account balance existing as of ~~natural~~May 31, 2023. The increased GCBA rate of $0.20 per therm will support timely recovery of the existing balance. Based on the design of base tariff gas ~~purchased. The difference between~~cost rates in Arizona and surcharges, the account balance existing as of that date is deemed generally recoverable over the next twelve months, and is therefore classified as a current ~~cost~~asset on the balance sheets of ~~gas purchased~~the Company and ~~the cost of gas recovered in billed rates is deferred. Generally, these deferred amounts are recovered or refunded within one year.~~Southwest.

Prepaid and other current assets. Prepaid and other current assets for the Company and Southwest include, among other things, materials and operating supplies of $~~76.5~~86.6 million at September 30, ~~2022~~2023 and $~~62.9~~77.3 million at December 31, ~~2021~~2022 (carried at weighted average cost). ~~For the Company, there were materials and operating supplies of~~ ~~$80.8 million~~ ~~and $67.4 million at September 30, 2022 and December 31, 2021, respectively, which included amounts for MountainWest.~~ Also included in the balance ~~for both Southwest and the Company~~ was ~~$15.5~~$207 million ~~and $51.6 million~~as of December 31, 2022 in unrecovered purchased gas costs, with no corresponding asset balance as of September 30, ~~2022 and December 31, 2021, respectively, in accrued purchased gas cost.~~2023.

Through management’s assessments, no impairment was deemed to have ~~occurred. However, there can be no assurances that future assessments of goodwill will not result in an impairment, and various factors, including changes~~occurred in the ~~business, strategic initiatives, economic conditions, governmental monetary policies, interest rates, or others, on their own or in combination with each other, could result in~~continuing segments of the ~~fair value of reporting units being lower than their carrying values.~~Company.

Included in the table above is the change in cash surrender values of COLI policies (including net death benefits recognized). Current tax regulations provide for tax-free treatment of life insurance (death benefit) proceeds. Therefore, changes in the cash surrender values of COLI policies, as they progress towards the ultimate death benefits, are also recorded without tax consequences. Interest income primarily relates to Southwest’s regulatory asset balances, including its deferred purchased gas cost ~~mechanisms.~~mechanisms, the combined balance of which increased from $381 million as of September 30, 2022 to $687 million as of September 30, 2023. Refer also ~~to the discussion of~~ ~~Other Property and Investments~~ ~~above and~~ to Note 2 – Components of Net Periodic Benefit Cost. Miscellaneous expense for Southwest includes a variety of items, including reserves for uncompleted software projects and held-for-sale assets (discussed above) at Southwest deemed non-recoverable from its utility operations.

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. Based on the fair value model employed, the estimated redemption value of the Linetec redeemable noncontrolling interest ~~decreased by~~increased approximately ~~$45~~$21.8 million during the nine months ended September 30, ~~2022.

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 September 30,		Nine Months Ended September 30,		Twelve Months Ended September 30,			Three Months Ended September 30,		Nine Months Ended September 30,		Twelve Months Ended September 30,

(1) The number of anti-dilutive restricted stock units excluded from the calculation of diluted shares during the three months ended September 30, 2022 is 168,000, and 192,000 during the twelve months ended September 30, 2023.

Income Taxes. The Company’s effective tax rate was (47.1)% for the three months ended September 30, 2023, compared to 11.9% for the corresponding period in 2022 primarily due to pre-tax income differences and the amortization of excess deferred income taxes. The Company’s effective tax rate was 28.2% for the nine months ended September 30, 2023, compared to 18.6% for the corresponding period in 2022 primarily due to amortization of excess deferred income taxes, company-owned life insurance (“COLI”), which is non-taxable and non-deductible, and the MountainWest sale, and also includes the impact of book versus tax basis differences related to the transaction (See Note 8 - Dispositions).

~~Contingencies.~~Southwest’s effective tax rate ~~Southwest maintains liability insurance~~was 65.3% for ~~various risks associated with~~ the ~~operation~~three months ended September 30, 2023, compared to 28.1% for the corresponding period in 2022 primarily due to pre-tax income differences, the amortization of ~~its~~excess deferred income taxes, and corporate-owned life insurance. Southwest’s effective tax rate was 12.9% for the nine months ended September 30, 2023, compared to 17.0% in the corresponding period in 2022, primarily due to the amortization of excess accumulated deferred income taxes and corporate-owned life insurance.

In April 2023, the Internal Revenue Service (“IRS”) 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 ~~pipelines~~transmission and ~~facilities. In connection with these liability insurance policies, Southwest is responsible~~distribution property must be capitalized for an initial deductible or self-insured retention amount per incident, after which the insurance carriers would be responsible for amounts up to the policy limits. For the policy year August 2022 to July 2023, these liability insurance policies require Southwest to be responsible for the first $1 million (self-insured retention) of each incident plus the first $4 million in aggregate claims above its self-insured retention in the policy year. In August 2021, a natural gas pipe operated by Southwest was involved in an explosion that injured four individuals and damaged property.tax purposes. The explosion was caused by a leak in the pipe, and is under investigation. Individuals that were injured have each brought legal claims against Southwest and other parties. If Southwest is deemed fully or partially responsible, Southwest estimates its net exposure could be equal to the self-insured retention of $5 million (the maximum noted above). In 2021, pursuant to Accounting Standards Codification 450, ~~Contingencies~~, Southwest recorded a $5 million liability related to this incident reflecting the maximum noted above; an estimate of actual loss greater than this exposure (to be covered by insurance) cannot be estimated as of the date these financial statements are issued.

Other contingencies are also recognized where appropriate, if claims are brought, or expected to be brought, against the Company or Southwest, where management expects it may settle (or be required to settle) claims in cash, or in some cases, by means of insurance indemnification. For instance, the balance of such reserves was updated in the second quarter of 2022 for $6.2 million related to a contract dispute. The amount was paid in the third quarter of 2022 and the matter is now closed.

~~As described above, the November 2021 civil suit filed by the Icahn Group against the~~ Company and ~~certain officers~~Southwest are currently reviewing this revenue procedure to determine the potential impact on their financial position, results of operations, and ~~directors was subject to a stipulation of dismissal with prejudice in May 2022, pursuant to the terms of the Initial Cooperation Agreement.~~

On November 18, 2021, the City Pension Fund for Firefighters and Police Officers in the City of Miami Beach (“City Pension Fund”) commenced a putative class action lawsuit in the Court of Chancery for the State of Delaware on behalf of a putative class of persons who purchased the Company’s stock. The complaint was later amended on November 30, 2021. The amended complaint named the Company and the individual members of the Board as defendants. The complaint sought to assert breach of fiduciary duty claims, alleging that the Board’s recommendation that stockholders reject Icahn’s Offer to purchase shares of the Company’s common stock omitted material information about the Company’s financial analysis; and sought to have the Board approve Icahn’s slate of nominees as “continuing directors” under certain of the Company’s debt instruments. In March 2022, the City Pension Fund filed a motion for summary judgment on its claim; however, in April 2022, the City Pension Fund filed a notice of withdrawal of its motion for summary judgment. The Company believes that the claims lack merit and intends to vigorously defend against them.cash flows.

Recent Accounting Standards Updates.

~~Accounting pronouncements effective or adopted in 2022:~~

~~In March 2020, the Financial Accounting Standards Board (the “FASB”)~~There are no recently issued ASU 2020-04 “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” The update provides optional guidance for a limited time to ease the potential burden in accounting for, or recognizing the effects of, reference rate reform on financial reporting, including when modifying a contract (during the eligibility period covered by the update to Topic 848) to replace a reference rate affected by such reform. The update applies only to contracts and hedging relationshipsstandards updates that ~~reference the London Interbank Offered Rate (“LIBOR”) or another rate~~are expected to be discontinued due to reference rate reform. The guidance was eligible to be applied upon issuance on March 12, 2020, and can generally be applied through December 31, 2022, and while a proposal by the FASB has occurred to extend the optional guidance to the full tenor of LIBOR expiration dates occurring after 2022, to date, no such update has been made effective. Management will monitor the impacts this update might have on the Company’s and Southwest’s consolidated financial statements and disclosures, and will reflect such appropriately, in the event that the optional guidance is elected. Management will also monitor further FASB action, if any, in regard to the full tenor of LIBOR expiration dates. See also LIBOR discussion in ~~Note 5 – Debt~~.

In August 2020, the FASB issued ASU 2020-06 “Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging— Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity.” The update, amongst other amendments, improves the guidance related to the disclosures and earnings-per-share for convertible instruments and contracts in an entity’s own equity.

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.~~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 defined benefit qualified retirement plan, SERP, and PBOP are not available to Southwest employees hired on or after January 1, 2022. Employees hired in 2022 or later periods are eligible for enhanced defined contributions as part of the Southwest 401(k) plan, rather than participating in the defined benefit retirement plan.

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.

The revenue earned on contracts in progress in excess of billings ~~(contract asset)~~ primarily relates to Centuri’s right to consideration for work completed but not billed and/or approved for billing at the reporting date. These contract assets are transferred to contracts receivable when the rights become unconditional. Contract assets increased $44.7 million during 2023 due primarily to continued revenue growth. The amounts billed in excess of revenue earned ~~(contract liability)~~ primarily relate to the advance consideration received from customers for which work has not yet been completed. The change in this contract liability balance from December 31, ~~2021~~2022 to September 30, ~~2022 is~~2023 increased $15.9 million due to ~~increases in cash~~amounts received for services not yet performed, net of revenue recognized, from contracts that commenced during the period, offset by revenue recognized of approximately $11.9 million that was included in this balance as of January 1, 2022, after which time it became earned and the balance was reduced.recognized.

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 September 30, ~~2022,~~2023, Centuri ~~had~~ h61ad 57 fixed 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 September 30, ~~2022~~2023 was ~~$430.3 million.~~$383 million. Centuri expects to recognize the remaining performance obligations over approximately the nenext ~~xt 2.7~~two ~~years;~~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.

~~Pipeline and Storage Segment:~~

MountainWest derives revenue on the basis of services rendered, commodities delivered, or contracts settled and includes amounts yet to be billed to customers. MountainWest generates revenue and earnings from annual reservation payments under firm peaking storage and firm transportation contracts. Straight-fixed-variable rate designs are used to allow for recovery of substantially all fixed costs in demand or reservation charges, thereby reducing the earnings impact of volume changes on gas transportation and storage operations.

MountainWest receives upfront payment for certain storage services it provides to customers, which are considered to be contract liabilities. These payments are amortized to revenue over the term of the contract.

The primary types of sales and service activities reported as revenue from contracts with customers are FERC-regulated gas transportation and storage services, and to a lesser extent, natural gas liquid (“NGL”) revenues consisting primarily of NGL processing services, and other revenue (including natural gas sales, and services related to gathering and processing activities, as well as miscellaneous service revenue).

Transportation and storage contracts are primarily stand-ready service contracts that include fixed reservation and variable usage fees. Fixed fees are recognized ratably over the life of the contract as the stand-ready performance obligations are satisfied, while variable usage fees are recognized when MountainWest has a right to consideration from a customer in an amount that corresponds directly with the value to the customer of the performance obligation completed to date. Substantially all of MountainWest’s revenues are derived from performance obligations satisfied over time, rather than recognized at a single point in time. Payment for most sales and services varies by contract type, but is typically due within a month of billing.

MountainWest typically receives or retains NGLs and natural gas from customers when providing natural gas processing, transportation, or storage services. MountainWest records the fair value of NGLs received as service revenue recognized over time and recognizes revenue from the subsequent sale of the NGLs to customers upon delivery. MountainWest typically retains some natural gas under certain transportation service arrangements, intended to facilitate performance of the service and allow for natural losses that occur. As the intent of the retention amount is to enable fulfillment of the contract rather than to provide compensation for services, the fuel allowance is not included in revenue.

MountainWest Regulated operations revenues on the Condensed Consolidated Statements of Income of the Company include revenue from contracts with customers, which is shown below, disaggregated by categories of sales and service activities.

MountainWest has certain multi-year contracts with fixed-price performance obligations that were unsatisfied (or partially unsatisfied) at the end of the reporting period, whereby revenue will be earned over time as MountainWest stands ready to provide service. These amounts are not material to the Company’s financial statements overall. MountainWest also has certain contract liabilities related to consideration received from customers with an obligation to transfer goods or services subsequent to the balance sheet date, amounts for which are generally consistent between December 31, 2021 and September 30, 2022 and are not material.

SOUTHWEST GAS HOLDINGS, INC.						Form 10-Q
SOUTHWEST GAS CORPORATION						September 30, ~~2022~~2023

Southwest has a $400 million credit facility that is scheduled to expire in April 2025. 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 September 30, ~~2022,~~2023, the applicable margin is 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 September 30, ~~2022,~~ ~~$138 million~~ ~~was outstanding on the long-term portion of the facility (no borrowings were outstanding under the commercial paper program, discussed below). No~~2023, no borrowings were outstanding on the ~~short-term~~long-term portion (including under the commercial paper program), nor under the short-term portion of the facility.

Southwest has a $50 million commercial paper program. Issuances under the commercial paper program are supported by Southwest’s revolving credit facility and, therefore, do not represent additional borrowing capacity under the credit facility. Borrowings under the commercial paper program, if any, are designated a~~s long-term debt. Interest rates for the program are calculated at the then current commercial paper rate. At September 30, 2022, as noted above, no~~ ~~borrowings were outstanding under the commercial paper program.~~

In March 2022, Southwest issued $600 million aggregate principal amount of 4.05% Senior Notes at a discount of 0.65%. The notes will mature in March 2032. Southwest used the net proceeds to redeem the $250 million 3.875% notes due in April 2022 and to repay outstanding amounts under its credit facility, with the remaining net proceeds used for general corporate purposes.

On September 26, 2022 (the “Amendment Date”), Southwest Gas Holdings, Inc., entered into Amendment No. 1 (“Amended Credit Agreement”) to the 364-day Term Loan Credit Agreement (the “Credit Agreement”). The Credit Agreement initially provided for a $1.6 billion delayed-draw term loan (the “Term Loan Facility”) to primarily fund the acquisition of the equity interests in MountainWest. As of the Amendment Date~~, approximately $1.15 billion in aggregate principal was outstanding under the Term Loan Facility, the same as that which was outstanding as of September 30, 2022.~~ ~~The Amended Credit Agreement, among other things, (1) exte~~nds the maturity date of the Term Loan to December 30, 2023, making the outstanding borrowings long-term as of September 30, 2022, and (2) replaces London Interbank Offered Rate (“LIBOR”) interest rate benchmarks with SOFR interest rate benchmarks. As part of the Amended Credit Agreement, the Company paid a non-refundable upfront fee in an amount equal to 0.10% of the aggregate principal amount outstanding as of the Amendment Date, and will pay additional fees based on any principal balance outstanding as of March 31, 2023, June 30, 2023, and September 30, 2023 of 0.10%, 0.15%, and 0.20%, respectively.

At September 30, ~~2022, $1.159~~2023, $1.141 billion in borrowings were outstanding under Centuri’s combined secured revolving credit and term loan facility. On November 4, 2022, Centuri amended the financial covenants of the revolving credit facility to increase the maximum total net leverage ratio during the period from December 31, 2022 through December 31, 2023. See ~~Note 9 - Subsequent Events~~ ~~for additional information about the amended credit facility.~~

In April 2023, Southwest Gas Holdings, Inc. entered into a $550 million Term Loan Credit Agreement (the “Term Loan”) that matures in October 2024. Interest rates for the Term Loan are calculated, at ~~their fair values as~~the Company’s option, at either SOFR plus an adjustment of 0.100% or the “alternate base rate,” plus in each case an applicable margin. Loans bearing interest with reference to SOFR have an applicable margin of 1.300% and loans bearing interest with reference to the alternate base rate have an applicable margin of 0.300%. SOFR is calculated with a floor of 0.000% and alternative base rate is calculated with a floor of 1.000%. Southwest Gas Holdings, Inc. utilized a majority of the ~~December 31, 2021 acquisition date~~proceeds to make an equity contribution to Southwest. On April 17, 2023, Southwest utilized the equity contribution to repay, in full, amounts outstanding under its then existing $450 million 364-day term loan, with the remainder of the ~~MountainWest entities.~~equity contribution used for working capital and general corporate purposes.

Short-Term Debt

Southwest Gas Holdings, Inc. has a ~~$200~~$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”~~rate,” plus in each case an applicable margin. There was ~~$156~~$57.5 million outstanding under this credit facility as of September 30, ~~2022.~~2023.

As indicated above, under Southwest’s $400 million credit facility, no short-term borrowings were outstanding at September 30, ~~2022.~~

In March 2022, Southwest amended its $250 million Term Loan (the “March 2021 Term Loan”), extending the maturity date to March 21, 2023 and replacing LIBOR interest rate benchmarks with SOFR interest rate benchmarks. The proceeds were

~~originally used to fund the increased cost of natural gas supply during the month of February 2021, caused by extreme weather conditions in the central U.S. There was~~ ~~$225 million~~ ~~outstanding under the March 2021 Term Loan as of September 30, 2022.~~

~~As disclosed in~~ ~~Note 1 – Background, Organization, and Summary of Significant Accounting Policies~~,the Company is exploring strategic alternatives, including a potential sale of MountainWest and/or Centuri. If MountainWest and/or Centuri is sold as part of the Strategic Review process, the proceeds will be used to repay the amounts borrowed to fund the acquisition. Otherwise, management intends to either issue long-term debt or equity securities to refinance the Term Loan Facility.

Management believes that its refinancing plan is probable based on the Company’s ability to generate consistent cash flows, its current credit ratings, its relationships with its lenders and its prior history of successfully raising debt and equity necessary to fund its acquisitions and operations. As such, management has concluded that the Company can satisfy its obligations for at least the next twelve months from the issuance date of these financial statements.

The Company’s ability to access capital markets or to otherwise obtain sufficient financing may be affected by future conditions. If the Company is unable to execute its plan to refinance debt obligations, the Company’s credit facility could be terminated, and amounts due under its revolver and other borrowing arrangements could be declared immediately due and payable.

~~LIBOR~~

~~Certain rates established at LIBOR were scheduled to be discontinued after 2021 as part of reference rate reform, while other LIBOR-based rates are scheduled to be discontinued after June~~ 2023. As of September 30, 2022, the Company had $1.009 billion in outstanding borrowings under Centuri’s term loan facility. Southwest, MountainWest, and Southwest Gas Holdings, Inc. had no outstanding borrowings or variable rate debt agreements with reference to LIBOR as of September 30, 2022.

Note 8 - Dispositions

Dispositions

In December ~~2021, Southwest Gas~~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 to Williams for $1.5 billion in total enterprise value, subject to certain adjustments. 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 September 2023, the Company announced that Centuri Holdings, Inc. ~~completed the acquisition of Dominion Energy Questar Pipeline, LLC and related entities (subsequently rebranded as “MountainWest”)~~, ~~which resulted in MountainWest becoming~~ a wholly owned subsidiary of the ~~Company. See~~Company formed for purposes of completing the ~~Company’s 2021~~separation (“Centuri Holdings”), had confidentially submitted a draft Registration Statement on Form ~~10-K for additional information about this acquisition.~~

~~Assets acquired and liabilities assumed in the transaction were recorded at their acquisition date fair values. Transaction costs associated~~S-1 with the ~~acquisition were expensed as incurred.~~SEC for a proposed initial public offering (“IPO”) of newly issued shares of Centuri Holdings common stock. The ~~majority~~IPO is subject to market and other conditions, the completion of the ~~operations acquired are~~SEC's review process, and the Board’s approval to proceed with the transaction. In the event an IPO is executed, the Company expects to maintain the option to either spin Centuri on a tax-free or taxable basis or sell down any remaining stake in a series of taxable sell downs following the IPO once the applicable lock-up period expires. The Company will continue to evaluate options for the separation following any IPO.

The fair value of the MountainWest assets held-for-sale was previously estimated based on the preliminary closing statement and subject to ~~FERC rate-regulation and therefore are accounted for pursuant to ASC 980,~~ ~~Regulated Operations. The fair values of MountainWest’s assets and liabilities, subject to rate making and cost recovery provisions, provide revenues derived from costs of service,~~certain adjustments, including a ~~return~~post-closing payment between the parties related to final working capital balances. The amount of the post-closing payment was finalized in May 2023. The Company recognized an additional loss on ~~investment of assets and liabilities included in rate base. Accordingly, the carrying values of such assets~~

sale of approximately $21 million during the quarter ended March 31, 2023. This reflects the accrued post-closing payment of $7.4 million related to cash and ~~liabilities were deemed to approximate their fair values. The fair value of~~net working capital balances above/below a contractual benchmark, with the ~~MountainWest~~remaining charge associated with other changes in the assets and liabilities ~~assumed~~ that ~~are~~were not subject to post-closing payment true-up provisions. The post-closing payment of $7.4 million effectively returned approximately the rate-regulation provisions discussed above include a 50% equity method investment, non-regulated property, plant and equipment, and long-term debt assumed; related fair values were determined using a market approach, income approach, or cost approach, as appropriate. Amounts relatedsame amount initially paid by Williams to ~~post-closing payments and deferred taxes were estimated as~~the Company at closing. The $7.4 million reduced Proceeds from the sale of businesses, net of cash acquired in the Company’s Condensed Consolidated Statements of Cash Flows.

As referred to in Note 7 – Segment Information, in September 2022, the Federal Energy Regulatory Commission (the “FERC”) issued an order initiating an investigation, pursuant to section 5 of the ~~acquisition date~~Natural Gas Act, to determine whether rates charged by MountainWest Overthrust Pipeline, LLC, a subsidiary of MountainWest, were just and ~~adjusted when determined during~~reasonable and setting the ~~period ended September 30, 2022.

However,~~parties agreed to a settlement, and as a result the ~~final purchase accounting has not yet been completed and further refinements may occur.~~

Note 9 - Subsequent Events

On ~~October 24, 2022,~~November 3, 2023, the Board authorized a dividend of one preferred stock purchase right (a “Right”) for each outstanding share of common stock, $1 par value per share, of the Company (the “Common Stock”). The dividend is payable on November 17, 2023 (the “Record Date”) to holders of record of Common Stock as of 5:00 P.M., New York City time, on the Record Date. The description and terms of the Rights are set forth in a Tax-Free Spin Protection Plan, dated as of November 5, 2023 (as may be amended from time to time, the “Plan”), between the Company and Equiniti Trust Company, LLC, as rights agent. Each Right entitles the ~~Icahn Group entered into~~registered holder to purchase from the ~~Amended Cooperation Agreement,~~Company one ten-thousandth of a share of Series A Junior Participating Preferred Stock, no par value per share, of the Company (the “Series A Preferred”), at a purchase price of $300.00 per one ten-thousandth of a share of Series A Preferred, subject to adjustment.

By adopting the Plan, the Board is seeking to preserve the Company’s ability to effectuate a separation of Centuri Holdings (the “Spin-Off Transaction”) that would be tax-free to the Company (the “Tax-Free Status”). While the Company intends that any Spin-Off Transaction, if effected, would qualify as a tax-free transaction to the Company’s stockholders, the ability to effect a spin-off that is tax-free to the Company (as opposed to its stockholders) could be lost if certain stock purchases (including by existing or new holders in the open market) are treated as part of a plan pursuant to which ~~amended, restated, superseded,~~one or more persons directly or indirectly acquire a 50% or greater interest in the Company (a “355 Ownership Change”) within applicable time periods for purposes of Section 355(e) of the Internal Revenue Code. The Company believes that there is minimal capacity for changes in the ownership of its stock before a 355 Ownership Change could occur. The Plan is intended to restrict acquisitions of Company stock that could cause a 355 Ownership Change and ~~replaced~~could impair the Company’s ability to effectuate a Spin-Off Transaction that has Tax-Free Status. The Board believes it is in the best interest of the Company and its ~~entirety~~stockholders to preserve the ~~Initial Cooperation Agreement.~~Company’s ability to effectuate a Spin-Off Transaction with Tax-Free Status.

~~In accordance~~For additional information regarding the Plan, refer to our current report on Form 8-K, as filed with the terms of the Amended Cooperation Agreement, the Company agreed with the Icahn Group, among other things, to nominate each of Andrew W. Evans, Henry P. Linginfelter, Ruby Sharma, and Andrew J. Teno (each, an “Icahn Designee” and, collectively, the “Icahn Designees”) for election at the Company’s 2023 annual meeting of stockholders (the “2023 Annual Meeting”). In addition, subject to qualifications set forth in the Amended Cooperation Agreement, the Amended Cooperation Agreement provides that the standstill restrictions on the Icahn Group will remain in effect until, and the Amended Cooperation Agreement will terminate upon, the later of (x) the conclusion of the 2023 Annual Meeting and (y) the earlier of


			32


~~SOUTHWEST GAS HOLDINGS, INC.~~						~~Form 10-Q~~
~~SOUTHWEST GAS CORPORATION~~						~~September 30, 2022~~

(1) immediately following the time at which Andrew J. Teno (or any Replacement Designee for Mr. Teno, as such term is defined in the Amended Cooperation Agreement) is no longer serving on the Board and (2) thirty (30) days prior to the expiration of the advance notice deadline for the submission of director nominees in connection with the Company’s 2024 Annual Meeting of Stockholders (as such term is defined in the Amended Cooperation Agreement); provided, however, that the Amended Cooperation Agreement will terminate automatically on the date on which the Board re-appoints as a director any former director of the Board (~~i.e.,~~ any person who was a director of the Board prior to the 2022 Annual Meeting, but was not a director of the Board immediately after the 2022 Annual Meeting), without the approval of a majority of the Icahn Designees.

Pursuant to the terms of the Amended Cooperation Agreement, the Company further agreed with the Icahn Group (i) to maintain one-year terms and annual elections for all directors serving on the Board through the term of the Amended Cooperation Agreement, (ii) to establish the record date for the 2023 Annual Meeting for a time within thirty (30) days of March 21, 2023, and (iii) that in the event that the Strategic Transactions Committee approves any separation of the Company’s businesses into two or more independent, publicly traded companies (any such separation, a “Spinoff” and each such resulting independent, publicly traded company, a “SpinCo”) during the term of the Amended Cooperation Agreement and while Icahn Group owns a Net Long Position of a number of shares of Common Stock that is at least 50% of the Tender Offer Closing Amount (each such term, as defined in the Amended Cooperation Agreement), any such SpinCo will be organized in Delaware, any such SpinCo’s board of directors will be annually elected for one-year terms and the first meeting of stockholders for such SpinCo will be held no earlier than the nine-month anniversary of the consummation of the Spinoff and no later than the twelve-month anniversary of the Spinoff, subject to certain exceptions set forth in the Amended Cooperation Agreement.

~~Additionally,~~SEC on November 4, 2022, Centuri amended the financial covenants of its revolving credit facility to increase the maximum total net leverage ratio during the period from December 31, 2022 through December 31, 2023 (the “Credit Facility Amendment”). The Credit Facility Amendment also transitioned the interest rate benchmark for the revolving credit facility from LIBOR to SOFR. The applicable margin for the revolving credit facility now ranges from 1.0% to 2.5% for SOFR loans and from 0.0% to 1.5% for CDOR and “base rate” loans, depending on Centuri’s total net leverage ratio. Further, the Credit Facility Amendment increases a letter of credit sub-facility from $100 million to $125 million. The Credit Facility Amendment did not modify any terms of the term loan facility.6, 2023.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Southwest Gas Holdings, Inc. is a holding company that owns all of the shares of common stock of Southwest Gas Corporation (“Southwest” or the “natural gas distribution” segment), and all of the shares of common stock of Centuri Group, Inc. (“Centuri,” or the “utility infrastructure services” segment)~~, as well as all of the common stock of the recently formed MountainWest Pipelines Holding Company (“MountainWest,” or the “pipeline and storage” segment)~~. Southwest Gas Holdings, Inc. and its subsidiaries are collectively referred to as the “Company.”

~~The Company completed the acquisition of Dominion Energy Questar Pipeline, LLC and related entities (“Questar Pipelines”) in~~In December ~~2021. Following the acquisition, the Company formed MountainWest, which owns all of the membership interests of Questar Pipelines. In April~~ 2022, the Company completed a general rebranding of the Questar Pipelines entities under the MountainWest name. The acquired operations further diversify the Company’s business including an essential Rocky Mountain energy hub with over 2,000 miles of highly contracted, FERC-regulated interstate natural gas pipelines providing transportation and underground storage services in Utah, Wyoming, and Colorado.

~~In October 2021, our~~announced that its Board of Directors (the “Board”) ~~authorized~~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 that closed on February 14, 2023. Additionally, the Company determined it would pursue a spin-off of Centuri (the “Centuri spin-off”), to form a new independent publicly traded utility infrastructure services company. In September 2023, the Company announced that Centuri Holdings, Inc., a wholly owned subsidiary of the Company formed for purposes of completing the separation of Centuri (“Centuri Holdings”), had confidentially submitted a draft registration statement on Form S-1 with the U.S. Securities and ~~declared~~Exchange Commission (the “SEC”) for the proposed initial public offering of newly issued shares of Centuri Holdings common stock. The Company remains committed to


			28

separating Centuri and continues to assess the value of a potential tax-free spin-off of Centuri, either following, or in lieu of, a potential initial public offering by Centuri as well as other transaction alternatives. See “Item1A - Risk Factors” and Note 8 - Dispositions in this Quarterly Report on Form 10-Q for more information.

On November 3, 2023, the Board authorized a dividend of one preferred stock purchase right (a “Right”) for each outstanding share of common stock, ~~outstanding~~$1 par value per share, of the Company (the “Common Stock”). The dividend is payable on November 17, 2023 (the “Record Date”) to ~~stockholders~~the holders of record atof Common Stock as of 5:00 P.M., New York City time, on the ~~close~~Record Date. The description and terms of ~~business on October 21, 2021, in accordance with~~ the ~~terms and conditions~~Rights are set forth in a Tax-Free Spin Protection Plan, dated as of November 5, 2023 (as may be amended from time to time, the ~~Rights Agreement. The Amended Rights Agreement expired on October 9, 2022, in accordance with its terms.~~

~~In March 2022, the Company announced that the Board had determined to separate Centuri from~~“Plan”), between the Company and ~~authorized management to complete the separation within nine to twelve months from the date of such announcement. In April 2022,~~Equiniti Trust Company, LLC, as a result of interest in the Company well in excess of a tender offer to other of our stockholders by an activist stockholder (affiliates of Carl C. Icahn), the Board authorized the review of a full range of strategic alternatives intended to maximize stockholder value. As part of this process, a strategic transactions committee of the Board, consisting entirely of independent directors, would evaluate a sale of the Company, as well as a range of alternatives, including, but not limited to, a separate sale of its business units and/or pursuing the spin-off of Centuri (collectively, the “Strategic Review”). On August 3, 2022, the Company announced that the Board had unanimously determined that the best path forward to maximize value for all stockholders is to (i) focus on the strategic plan and while concluding the strategic review process for Southwest Gas Holdings, Inc. and Southwest Gas Corporation; (ii) continue to review strategic alternatives for MountainWest; and (iii) continue to review strategic alternatives for Centuri, including a sale or spin-off of Centuri, among others. There can be no assurances that the strategic alternatives considered will be executed or maximize value as intended. See “~~Item 1A - Risk Factors” included in the Company’s Quarterly Report on Form 10-Q filed May 10, 2022.~~

~~As described in~~ ~~Note 1 – Background, Organization, and Summary of Significant Accounting Policies~~, on May 6, 2022, the Company entered into the Initial Cooperation Agreement with the Icahn Group. Pursuant to the Initial Cooperation Agreement, the Company, among other things, made certain previously disclosed changes to the Board of Directors and management team. On October 24, 2022, the Company and the Icahn Group entered into the Amended Cooperation Agreement, which amended, restated, superseded, and replaced in its entirety the Initial Cooperation Agreement. Under the Amended Cooperation Agreement, certain of the standstill provisions in the Initial Cooperation Agreement were extended, the Ichan Group’s governance rights ~~were amended and the Company agreed to certain actions in connection with the 2023 Annual Meeting. Please see~~agent. See Note 9 - Subsequent Events in this Quarterly Report on Form 10-Q for ~~additional information about the Amended Cooperation Agreement.~~more information.

Southwest is engaged in the business of purchasing, distributing, and transporting natural gas for customers in portions of Arizona, Nevada, and California. Southwest is the largest distributor of natural gas in Arizona and Nevada, and distributes and transports natural gas for customers in portions of California. Additionally, through its subsidiaries, Southwest operates two regulated interstate pipelines serving portions of ~~the northern territories of Nevada and California.~~Southwest’s service territories.

As of September 30, ~~2022,~~2023, Southwest ~~had~~ ~~2,180,000~~had 2,211,000 residential, commercial, industrial, and other natural gas customers, of which ~~1,166,000~~1,184,000 customers were located in Arizona, ~~810,000~~822,000 in Nevada, and ~~204,000~~205,000 in California. ~~In January 2022, approximately 5,300 customers became part of Southwest’s gas distribution operations that were formerly served by Graham County Utilities (“GCU”).~~ Over the past twelve months, first-time meter sets were approximately ~~40,000~~,41,000, compared to ~~37,000~~40,000 for the twelve months ended September ~~2021.~~2022. Residential and small commercial customers represented over 99% of the total customer base. During the twelve months ended September 30, ~~2022,~~ 2023, 54% of operating margin (Regulated operations revenues less the net cost of gas sold) was earned in Arizona, 34% in Nevada, and 12% in California. During this same period, ~~Southwest earn~~Southwe~~ed 85%~~st earned 84% of its operating margin from residential and small commercial customers, 4%5% from other sales customers, and 11% frf~~rom~~om transportation customers. These patterns are expected to remain materially consistent for the ~~foreseeable~~foreseeable future.

Southwest recognizes operating revenues from the distribution and transportation of natural gas (and related services) to customers. Operating margin is a financial measure defined by management as Regulated operations revenues less the net cost


			35


~~SOUTHWEST GAS HOLDINGS, INC.~~						~~Form 10-Q~~

of gas sold. However, operating margin is not specifically defined in accounting principles generally accepted in the United States (“U.S. GAAP”). Thus, operating margin is considered a non-GAAP measure. Management uses this financial measure because Regulated operations revenues include the net cost of gas sold, which is a tracked cost that is passed through to customers without markup under purchased gas adjustment (“PGA”) mechanisms. Fluctuations in the net cost of gas sold impact revenues on a dollar-for-dollar basis, but do not impact operating margin or operating income. Therefore, management believes operating margin provides investors and other interested parties with useful and relevant information to analyze Southwest’s financial performance in a rate-regulated environment. The principal factors affecting changes in operating margin are general rate relief (including impacts of infrastructure trackers) and customer growth. Commission decisions on the amount and timing of relief may impact our earnings. Refer to the Summary Operating Results table below for a reconciliation of gross margin to operating margin, and refer to Rates and Regulatory Proceedings in this Management’s Discussion and Analysis, for details of various rate proceedings.

The demand for natural gas is seasonal, with greater demand in the colder winter months and decreased demand in the warmer summer months. All of Southwest’s service territories have decoupled rate structures (alternative revenue programs), which are designed to eliminate the direct link between volumetric sales and revenue, thereby mitigating the impacts of unusual weather variability and conservation on operating margin, allowing Southwest to pursue energy efficiency initiatives.

Centuri is a strategic infrastructure services company that partners with regulated utilities to build and maintain the energy network that powers millions of homes and businesses across the United States (“U.S.”) and Canada. With an unwavering commitment to serve as long-term partners to customers and communities, Centuri’s employees enable regulated utilities to safely and reliably deliver natural gas and electricity, as well as achieve their goals for environmental sustainability. Centuri operates in 7182 primary locations across 45 states and provinces in the U.S. and Canada. ~~Centuri~~It operates in the U.S., primarily as NPL, Neuco, Linetec, and Riggs Distler, and in Canada, primarily as NPL Canada.

Utility infrastructure services activity can be impacted by changes in infrastructure replacement programs of utilities, weather, and local and federal regulation (including tax rates and incentives). Utilities continue to implement or modify system integrity management programs to enhance safety pursuant to federal and state mandates. These programs have resulted in multi-year utility system replacement projects throughout the U.S. Likewise, there has been similar attention placed on electric grid modernization through national infrastructure legislation and related initiatives. The Department of Energy estimates more than 70% of the nation’s grid transmission lines and power transformers are over 25 years old, creating vulnerability exacerbated by seasonal storm and extreme weather events.Generally, Centuri revenues are lowest during the first quarter of the year due to less favorable winter weather conditions. Revenues typically improve as more favorable weather conditions occur during the summer and fall months. In cases of severe weather, such as following a regional storm, Centuri may be engaged to perform restoration activities related to above-ground utility infrastructure, and related results impacts are not solely within the control of management. In addition, in certain circumstances, such as with large bid contracts (especially those of a longer duration), or unit-price contracts with revenue caps, results may be impacted by differences between costs incurred and those anticipated when the work was originally bid. Work awarded, or failing to be awarded, by individual large customers can impact operating results.

MountainWest is an interstate natural gas transmission pipeline company that provides transportation and underground storage services to customers in Utah, Wyoming, and Colorado. A substantial portion of its revenue results from reservation charges, but variable rates are also included as part of its primarily rate-regulated rate structures.

While the novel coronavirus (“COVID-19”) pandemic has been ongoing since the first quarter of 2020, to date, there has not been a significant disruption in the Company’s supply chains, transportation network, or ability to serve customers. The extent to which COVID-19 may adversely impact the Company’s business depends on future developments; however, management does not currently expect impacts to be material to the Company’s liquidity or financial position overall.

All of our businesses may be impacted by economic conditions that impact businesses generally, such as inflationary impacts on goods and services consumed in the business, rising interest rates, labor markets and costs (including in regard to contracted or professional services), and the availability of those resources. Certain of these impacts may be more predominant in certain of our operations, such as with regard to fuel costs for work equipment and skilled/trade labor costs at Centuri.

Utility infrastructure services revenues increased ~~$125.6~~$16.4 million in the third quarter of ~~2022~~2023 when compared to the prior-year quarter, ~~including~~driven primarily by a $45 million increase in offshore wind revenue and an increase ~~of $89 million from Riggs Distler, which was acquired on August 27, 2021. Revenues from~~in electric infrastructure services ~~increased $33.8~~revenue of $11.3 million, partially offset by a decrease in ~~the third quarter~~gas infrastructure services revenue (discussed below). Offshore wind revenue is reflected as a component of ~~2022 when compared~~other revenues (refer to ~~the prior-year quarter,~~Note 3 – Revenue in this Quarterly Report on Form 10-Q). The increase in offshore wind revenue was offset in part by a $15.2 million decline in other revenues due to timing of ~~which $27.9 million was recorded by Riggs Distler. Included~~work completed. This revenue stems from four multi-year contracts whereby Centuri provides materials, subcontracts manufacturing, and self-performs fabrication and assembly of secondary steel components onshore, with delivery at a port facility. The increase in electric infrastructure services revenues was due to higher volumes under certain existing customer master service agreements. Included in ~~the third quarter of 2022~~electric infrastructure revenue was ~~$17.5~~$18.9 million from emergency restoration services ~~performed by Linetec, Riggs Distler,~~following tornado and ~~National Powerline following~~other storm damage to customers’ above-ground utility infrastructure in and around the Gulf Coast and eastern regions of the U.S. ~~and Canada,~~, compared to ~~$45.7~~$17.5 million in storm restoration work in the same quarter in the prior ~~year period.~~year. Centuri’s revenues derived from storm-related services vary from period to period due to the unpredictable nature of weather-related events, and when this type of work is performed, it typically generates a higher profit margin than core infrastructure services, due to improved operating efficiencies related to equipment utilization and absorption of fixed costs. ~~The current quarter~~Despite an increase ~~also includes approximately $74.6~~in bid revenue of $24.4 million inwith a U.S. gas infrastructure services ~~revenues, including $14~~customer, gas infrastructure services revenue overall decreased $24.7 million ~~recorded by Riggs Distler,~~during the third quarter of 2023 primarily ~~from increased~~due to a net decrease in volumes under existing customer master service ~~agreements.

Utility infrastructure services expenses increased ~~$112.9~~$5.6 million in the third quarter of ~~2022~~2023 when compared to the prior-year quarter, ~~including increases~~primarily as a result of ~~$83.8~~increased costs to complete a higher volume of work and due to higher incentive compensation from improved results. General and administrative costs that are included in Utility infrastructure services expense overall increased $4.3 million ~~incurred by Riggs Distler in 2022 when~~between comparative quarters, and include incentive compensation. Subcontractor costs increased during the third quarter of 2023 compared to the prior-year quarter, ~~and incremental costs related to~~in association with the higher volume of work ~~otherwise.

Despite continued inflationary pressures, margin on work completed in the third quarter of 2023 improved due to changes in the mix of work ~~including~~and lower ~~volumes of storm related activities, and inflation led to higher input costs, including~~ fuel and subcontractor expenses, as well as increased project related travel and equipment rental costs incurred by the electric infrastructure business. Fuel costs alone increased $9.5 million in the current quarter, including $1.6 million incurred by Riggs Distler. A loss of $5.7 million was incurred on a gas infrastructure bid project during the current quarter due to higher costs than anticipated. This project is anticipated to reach substantial completion by the end of 2022, and additional compensation is being pursued with the customer. Increased project-related travel expenses of $4.5 million were incurred during the period. Also included in total Utility infrastructure services expenses were general and administrative costs, which decreased approximately $18 million between quarters, primarily due to acquisition costs of $13 million incurred in the prior year quarter in connection with the acquisition of Riggs Distler in addition to lower incentive compensation incurred during the current quarter.prices.

Rates and Regulatory Proceedings

Southwest is subject to the regulation of the Arizona Corporation Commission ~~(the “ACC”~~(“ACC”), the Public Utilities Commission of Nevada (the “PUCN”), the California Public Utilities Commission (the “CPUC”), and two of Southwest’s subsidiaries are subject to regulation by the Federal Energy Regulatory Commission (the “FERC”). Due to the size of Southwest’s regulated operations and the frequency of rate cases and other procedural activities with its commissions, the following discussion focuses primarily on the proceedings within its natural gas distribution operations.

~~General Rate Relief and Rate Design~~

Rates charged to customers vary according to customer class and rate jurisdiction and are set by the individual state and federal regulatory commissions that govern Southwest’s service territories. Southwest makes periodic filings for rate adjustments as the cost of providing service changes (including the cost of natural gas purchased), and as additional investments in new or replacement pipeline and related facilities are made. Rates are intended to provide for recovery of all commission-approved costs and a reasonable return on investment. The mix of fixed and variable components in rates assigned to various customer classes (rate design) can significantly impact the operating margin actually realized by Southwest. Management has worked with its regulatory commissions in designing rate structures that strive to provide affordable service to customers while mitigating volatility in prices to customers and stabilizing returns to investors. Such rate structures were in place in all of Southwest’s operating areas during all periods for which results of natural gas distribution operations are disclosed above.

Arizona Jurisdiction

Arizona General Rate Case. ~~In December 2021,~~ Southwest filed a general rate case application ~~proposing a revenue increase of approximately $90.7 million. Although updated rates related to the previous rate case became effective~~ in ~~January 2021, the most significant driver for the~~ December 2021, ~~request was the necessity~~primarily to reflect in rates the substantial capital investments that ~~have been~~were made since the end of the test year in ~~the previous~~an earlier case, including ~~the customer information system implemented~~investments in a

customer information system implemented in May 2021. The filing was based on a test year ended August 31, 2021 and proposed a return on common equity of 9.90% relative to a target equity ratio of 51%. Southwest also proposed a twelve-month post-test year adjustment to reflect otherwise non-revenue producing plant in service as of August 31, 2022 and certain expense adjustments. Recovery (over three years) of the approximately $12 million related to the outstanding deferral balance associated with the LNG facility (see below) was included in the request, along with the approximate $2.1 million (also over three years) in late payment charges that were suppressed from customer accounts during the COVID-19 pandemic. A request to continue the Delivery Charge Adjustment (“DCA”), Southwest’s full-revenue decoupling mechanism, was also included, while no changes to Southwest’s existing rate design are proposed.

At a hearing held in September 2022, Southwest, the ACC’s Utilities Division Staff (the “Staff”), and the Residential Utility Consumer Office jointly stipulated to several issues, including a target capital structure consisting of 50% equity and 50% debt; a 9.30% return on equity; and foregoing ~~recovery of the requested COVID-19 moratorium waived late fees, as well as an acquisition~~a premium related to the ~~recent~~ Graham County ~~acquisition. Among~~acquisition as well as the ~~uncontested issues identified prior~~recovery of $12 million of waived late fees on customer account balances that would have otherwise applied to delinquent accounts in the absence of a COVID-19 moratorium on such fees. Approximately $12 million in costs related to the hearing were the continuation of the DCA mechanism, the continuation of the existing rate design, and Southwest’s alternate property tax expense calculation, reflecting actual incurred property tax expenseLiquefied Natural Gas facility deferred in ~~2021, instead of~~an authorized regulatory asset was approved to be amortized over four years. The ACC’s final order authorized a pro-forma adjustment reflecting forecasted property tax expense. Although these issues were resolved amongst the parties, these and other items in the case are still subject to the Administrative Law Judge’s recommended order and opinion that will be considered by the ACC. A decision and resulting$54.3 million increase, with new rates ~~are anticipated in the first quarter~~effective February 1, 2023.

Delivery Charge Adjustment. The ~~DCA~~Delivery Charge Adjustment (“DCA”) is filed each April, which along with other reporting requirements, contemplates a rate to return/recover the over- or under-collected margin tracker (decoupling mechanism) balance. AnThe most recent filing was made in April ~~2022~~2023 to request ~~proposed~~ a rate to ~~return $10.5 million,~~address the over-collected balance of $53.5 million existing atas of March 31, 2023. The requested rate to return the ~~end of the first quarter 2022, which~~over-collected balance was approved and new rates became effective ~~July~~August 1, ~~2022.~~2023.

Tax Reform. ~~In the most recently concluded Arizona general rate proceeding, a~~A Tax Expense Adjustor Mechanism (“TEAM”) was approved in Southwest’s 2019 general rate case to timely recognize tax rate changes resulting from federal or state tax legislation following the TEAM implementation. In addition, the TEAM tracks and returns/recovers the revenue requirement impact of changes in amortization of ~~EADIT (including~~excess accumulated deferred income taxes (“EADIT”), including that which resulted from 2017 U.S. federal tax ~~reform)~~reform, compared to the amount authorized in the most recently concluded rate case. InFollowing inaugural surcredit rate establishment under the TEAM mechanism, in December ~~2021,~~2022, Southwest filed its ~~inaugural~~most recent TEAM rate application, which proposed an approximate $4.7 million refund, comprised of an approximate $9 million decrease in revenue requirement offset by an under-collected balance of approximately $4.3 million. Staff issued a proposed order supportingproposing to update the TEAM ~~credit,~~surcredit to refund $6.5 million of estimated net EADIT savings, which was approved by the ACC ~~with rates~~effective May 1, 2023 and will be further updated effective November 1, ~~2022.~~

~~Liquefied Natural Gas (“LNG”) Facility~~. In 2014, Southwest sought ACC preapproval to construct, operate, and maintain a 233,000 dekatherm LNG facility in southern Arizona. This facility is intended to enhance service reliability and flexibility related to natural gas deliveries in the southern Arizona area by providing a local storage option, connecting directly to Southwest’s distribution system. Southwest was ultimately granted approval for construction and deferral of costs. The facility was placed in service in December 2019. The capital costs and the operating expenses associated with plant operation were approved and considered as part of Southwest’s previous general rate case. Approximately $12 million in costs, incurred following the in-service date of the facility and after the period considered as part of the previous general rate case, were deferred as part of the previously authorized regulatory asset account, and are included for consideration in the current general rate case application.2023.

Customer-Owned Yard Line (“COYL”) Program. Southwest originally received approval, in connection with its 2010 Arizona general rate case, to implement a program to conduct leak surveys, and if leaks were present, to replace and relocate service lines and meters for Arizona customers whose meters were set off from the customer’s home, representing a non-traditional configuration. AThe COYL program has been subject to proceedings to recover investments since that time. In February 2023, Southwest requested approval to recover the outstanding revenue requirement of approximately $4.3 million associated with 2022 COYL investments, which increased the COYL recovery rate. The new rate became effective July 1, 2023.

PGA Modification. On March 1, 2023, Southwest filed a request to adjust the interest rate applicable to the outstanding Purchased Gas Adjustment (“PGA”) balance to more closely match the interest expense incurred to finance the balance. In the alternative, the filing ~~in May 2021 proposed~~requested an expansion of the ~~recovery of previously unrecovered surcharge revenue from 2019 and 2020 (collectively, $13.7 million) over a one-year period. Such amounts related~~current gas cost balancing account (“GCBA”) adjustment to ~~plant investments that were made in advance of those periods.~~clear the then existing $351 million balance. In ~~November 2021,~~July, the ACC approved ~~full~~an increase to the GCBA rate (over a two-year period) effective August 1, 2023, to support the timely recovery ~~within~~of the ~~proposed timeline, the rate for which was implemented the same month.

Recovery of~~under- or over-collected balance exceeds $10 million. The ongoing deferred energy rates, separate from the ~~remaining investments is ongoing.~~

~~Vintage Steel Pipe (“VSP”) Program.~~ Southwest received approval, in connection with its 2016 Arizona general rate case, to implement a VSP replacement program, due to having a substantial amount of pre-1970s vintage steel pipe in Arizona. However, as part of Southwest’s most recent rate case decision in 2020, the ACC ultimately decided to discontinue the accelerated VSP program. A filing in May 2021 proposed the recovery of previously unrecovered surcharge revenue relating to investments during 2019 and 2020, with approximately $60 million to be recovered over a three-year period. In November

~~2021, the ACC approved full recovery over the proposed three-year timeline with updated~~GCBA rates, ~~which became effective in March 2022.~~

~~Graham County Utilities.~~ In April 2021, Southwest and Graham County Utilities, Inc. (“GCU”) filed a joint application with the ACC for approval to transfer assets of GCU to Southwest and extend Southwest’s Certificate of Public Convenience and Necessity to serve the more than 5,000 associated customers, for a purchase price of $3.5 million. Approval of the application by the ACC was received in December 2021, with final transfer in mid-January 2022. Former GCU customers continue to be served under existing GCU rates until such time as they are rolled into Southwest’s rates, which is proposed to take place in conjunction with the effective date of rates resulting from the currently pending Arizona general rate case. Resolution is expected in the first quarter of 2023. See also ~~Arizona General Rate Case~~ ~~above and the discussion of stipulation by the parties to the pending case in regard to GCU.~~

~~California Jurisdiction~~

~~California General Rate Case.~~ Southwest’s most recent general rate case was concluded following an agreement in principle with the Public Advocate’s Office, which was unanimously approved by the CPUC on March 25, 2021, including a $6.4 million total combined revenue increase with a 10% return on common equity, relative to a 52% equity ratio. Approximately $4 million of the original proposed increase was associated with a North Lake Tahoe project that would not ultimately be completed by the beginning of 2021; consequently, the parties agreed to provide for recovery of the cost of service impacts of the project through the annual attrition filing. The rate case decision maintains Southwest’s existing 2.75% annual attrition adjustments and the continuation of the pension balancing account. It also includes cumulative expenditures totaling $119 million over the five-year rate cycle to implement risk-informed proposals, consisting of a school COYL replacement, meter protection, and pipe replacement programs. New rates were ultimately implemented April 1, 2021, with Southwest permitted to establish a general rate case memorandum account to track the impacts of a delay in the implementation of new rates (between January 1, 2021 and the date rates were implementation) for purposes of later recovery.

~~Attrition Filing.~~ Following the 2021 implementation of rates approved as part of the general rate case, Southwest is also authorized to continue annual Post Test Year (“PTY”) attrition increases of 2.75%, the first of which began in January 2022.

~~Customer Data Modernization Initiative (“CDMI”).~~ In April 2019, Southwest filed an application with the CPUC seeking authority to establish a two-way, interest-bearing balancing account to record costs associated with the CDMI to mitigate adverse financial implications related to the multi-year project (including a new customer information system, ultimately implemented in May 2021). Effective October 2019, the CPUC granted a memorandum account, which allowed Southwest to track costs, including operations and maintenance costs and capital-related costs, such as depreciation, taxes, and return associated with California’s portion of the CDMI (initially estimated at $19 million). The balance tracked in the memorandum account was transferred to the two-way balancing account in July 2020. A rate to begin recovering the balance accumulated through June 30, 2020 was established and made effective September 1, 2020, and updated ~~multiple times since, including in January 2022. This rate is expected to be updated at least annually.~~monthly.

~~Carbon Offset Program.~~ In March 2022, Southwest filed an application to seek approval to offer a voluntary program to California customers to purchase carbon offsets in an effort to provide customers additional options to reduce their respective GHG emissions. A request to establish a two-way balancing account to track program-related costs and revenues was included as part of the application. The CPUC issued Decision 22-09-010 dismissing Southwest’s application without prejudice. Southwest intends to file a new application in the fourth quarter 2022 addressing the concerns raised by third parties, which included a request to demonstrate that purchased offsets would result in GHG emissions reductions.

~~Building Decarbonization.~~ CPUC Decision 22-09-026 was issued regarding the elimination of gas line extension monetary allowances, a 10-year refundable payment option, and the 50% discount payment option for both residential and non-residential customers of all gas utilities. This applies to new applications for gas line extensions submitted on or after July 1, 2023. Although this decision eliminates the various allowances related to line extensions, it does not preclude extending natural gas service to customers.

~~Residential Disconnection Protections.~~ Decision 22-08-037 was issued by the CPUC establishing disconnection protections for residential customers of small and multi-jurisdictional utilities, including Southwest. A similar decision was adopted for four large California utilities in 2020. This decision prohibits the utility from assessing credit deposits for residential customers establishing or re-establishing service and prohibits the assessment of reconnection fees for residential customers among other provisions. The decision, however, also provides authorization to establish a two-way balancing account to track residential uncollectible charges for future recovery in a general rate case subject to relevant cap.

Nevada Jurisdiction

Nevada General Rate Case. Southwest filed its most ~~recently concluded Nevada~~recent general rate case in ~~August 2021, which was further updated by~~September 2023 proposing a ~~certification filing in December 2021. The request proposed a~~ combined statewide revenue increase of ~~approximately $28.7~~$69.8 million ~~(as of the certification date); the most significant driver for which was the substantial capital investments that were made since the end of~~based on the test year ~~in the previous case, including the customer information system that was implemented in~~ended May ~~2021.~~2023. The ~~filing included~~request includes a proposed return on common equity of ~~9.90% with~~10.0% relative to a 50% target equity ~~ratio of 51%; recovery~~ratio; an increase in rate base of approximately ~~$6.6 million in previously deferred late payment charges related to a regulatory asset associated with COVID-19; and~~$250 million; continuation of full revenue decoupling under the General Revenues Adjustment (“GRA”) ~~mechanism. On~~mechanism; recovery of approximately $4 million in incremental leak survey costs; the inclusion of new depreciation rates supported by a depreciation study that proposes to increase depreciation rates by $7.8 million; and to reflect in rates a level of operations and maintenance expense representative of current costs. New rates are anticipated in April 2024. Southwest’s previous general rate case concluded in February 7, 2022, ~~the parties filed a stipulation~~ with the PUCN, providing for a statewide revenue increase of $14.05 million, a return on common equity of 9.40% relative to a 50% target equity ratio, and continuation of Southwest’s full revenue decoupling mechanism. The stipulation was approved by the PUCN, and new rates ~~became~~ effective April 1, 2022. ~~The PUCN’s order did not include recovery of the approximate $6.6 million in deferred late payment charges related to a regulatory asset associated with COVID-19, which had previously been reserved.~~

General Revenues Adjustment. ~~As noted above, the continuation of the~~The GRA was affirmed as part of Southwest’s most ~~recent~~recently concluded general rate case with an expansion to include a large customer class (with average monthly throughput requirements greater than 15,000 therms), effective April 2022. Southwest makes Annual Rate Adjustment (“ARA”) filings to update rates to recover or return amounts associated with various regulatory mechanisms, including the GRA. Southwest made its most recent ARA filing in November ~~2021 related to balances as of September 30, 2021. New rates related to that filing became effective July 1, 2022. The next ARA filing will be made in November~~ 2022 related to ~~balances as of September 2022, with new rates expected to become effective July 1, 2023. While there is no impact to net income overall from adjustments to recovery rates associated with~~ the ~~related regulatory balances, operating cash flows are impacted by such changes.~~

~~COYL Program.~~ In August 2021, Southwest filed a joint petition with the Regulatory Operations Staff of the PUCN proposing a Nevada COYL replacement program to include residential COYLs, public school COYLs, and any other COYLs that are identified to be a safety concern. The petition was approved in January 2022 and provides for capital investments up to $5approximate $19 million ~~per year for five years and the establishment of a regulatory asset to track the capital-related costs. After five years, the program will be reassessed to determine if it should be continued.~~

~~Infrastructure Replacement Mechanism.~~ In 2014, the PUCN approved final rules for the Gas Infrastructure Replacement (“GIR”) mechanism, which provided for the deferral and recovery of certain costs associated with accelerated replacement of qualifying infrastructure that would not otherwise provide incremental revenues between general rate cases. Associated with the replacement of various types of pipe infrastructure under the mechanism (Early Vintage Plastic Pipe, COYL, and VSP), the related regulations provide Southwest with the opportunity to file a GIR “Advance Application” annually to seek preapproval of qualifying replacement projects.

In cases where preapproval of projects has been requested and granted, a GIR rate application has been separately filed to reset the GIR recovery surcharge rate related to previously approved and completed projects. On September 27, 2022, Southwest filed its latest rate application to reset the recovery surcharge in January 2023 to include cumulative deferrals through August 31, 2022. However, in November 2022, Southwest reached a settlement with parties (stipulation expected to be filed the same month) to discontinue the GIR, with no further ratemaking following the current year. An immaterial GIR balance ~~existed~~ as of September 30, 2022. ~~Commission approval~~Given the magnitude of the ~~stipulation is anticipated to be received in December 2022.~~

~~Conservation and Energy Efficiency.~~ The PUCN allows deferral (and later recovery) of approved conservation and energy efficiency costs, recovery rates for which are adjusted in association with ARA filings. In its November 2021 ARA filing, Southwest proposed annualized margin decreases of $574,000 and $434,700 for southern and northern Nevada, respectively, which became effective in July 2022. Separately, in May 2022, Southwest filed an application seeking approval of its annual Conservation and Energy Efficiency Plan Report for 2021, with no proposed modifications to the previously approved $1.3 million annual budget for years 2022-2024. The parties reached a stipulation that was approved by the PUCN in July 2022.

~~Expansion and Economic Development Legislation~~. In January 2016, final regulations were approved by the PUCN associated with legislation (“SB 151”) previously introduced and signed into law in Nevada. The legislation authorized natural gas utilities to expand their infrastructure to provide service to unserved and underserved areas in Nevada.

~~In November 2017, Southwest filed for preapproval of a project to extend service to Mesquite, Nevada, in accordance~~outstanding balances, further discussion with the ~~SB 151 regulations. Ultimately,~~parties resulted in a settlement of the ~~PUCN issued an order approving Southwest’s proposal for the expansion,~~issues and ~~Southwest provides periodic updates and adjusts~~utilizing a more current GRA balance of approximately $12 million as of January 2023 to more closely align the rates ~~to recover the revenue requirement associated~~implemented with the ~~investments to serve customers~~existing balance.

The PTY margin increase of approximately $1.3 million associated with the project became effective February 1, 2023.

FERC Jurisdiction

~~Great Basin General Rate Case.~~ In 2020, Great Basin Gas Transmission Company (“Great Basin”), a wholly owned subsidiary of Southwest, reached an agreement in principle with the FERC Staff providing that its three largest transportation customers and all storage customers would be required to have primary service agreement terms of at least five years, that term-differentiated rates would continue generally, and included a 9.90% pre-tax rate of return. Interim rates were made effective February 2020. As part of the settlement, Great Basin will file a rate case no later than May 31, 2025.

MountainWest Overthrust Pipeline. On September 22, 2022, during the period of Southwest Gas Holdings’ ownership of the MountainWest entities, the FERC issued an order initiating an investigation, pursuant to section 5 of the Natural Gas Act, to determine whether rates ~~currently~~ charged by MountainWest Overthrust Pipeline, LLC, ~~(“Overthrust Pipeline”) are~~a subsidiary of MountainWest, were just and reasonable and setting the matter for ~~hearing.~~hearing (the “Section 5 Rate Case”).

PGA Filings

The rate schedules in all of Southwest’s service territories contain provisions that permit adjustment to rates as the cost of purchased gas changes. These deferred energy provisions and purchased gas adjustment clauses are collectively referred to as “PGA” clauses. Differences between gas costs recovered from customers and amounts paid for gas by Southwest result in over- or under-collections. Balances are recovered from or refunded to customers on an ongoing basis with interest. As of September 30, ~~2022,~~2023, under-collections in each of Southwest’s service territories resulted in an asset of ~~$381~~$687 million on the Company’s and Southwest’s Condensed Consolidated Balance Sheets. ~~See also~~ ~~Deferred Purchased Gas Costs~~ in ~~Note 1 – Background, Organization, and Summary of Significant Accounting Policies~~ ~~in this quarterly report on Form 10-Q~~.

Filings to change rates in accordance with PGA clauses are subject to audit by state regulatory commission staffs. PGA changes impact cash flows but have no direct impact on operating margin. However, gas cost deferrals and recoveries can impact comparisons between periods of individual consolidated income statement components. These include Regulated operations revenues, Net cost of gas sold, Net interest deductions, and Other income (deductions).

Capital Resources and Liquidity

Historically, cash on hand and cash flows from operations have provided a substantial portion of cash used in investing activities (primarily for construction expenditures and property additions). In recent years, Southwest has undertaken significant pipe replacement activities to fortify system integrity and reliability, including on an accelerated basis in association with certain gas infrastructure replacement programs. This activity has necessitated the issuance of both debt and equity securities to supplement cash flows from operations. ~~The Company, in executing on its plans~~More recently, a number of conditions, such as winter storms and market forces (including historically low storage levels) have caused gas prices to ~~fund the MountainWest acquisition, initially funded the transaction through short-term borrowings, which was expected~~spike and remain higher during extended periods as

The ~~prior period~~decline in cash flows also ~~included a $50 million discretionary supplemental contribution to~~resulted from the ~~noncontributory qualified retirement plan (reflected as a change in other liabilities and deferred credits).

Investing Cash Flows. Cash ~~used in~~flows from consolidated investing activities ~~decreased $710~~increased $961 million in the first nine months of ~~2022~~2023 as compared to the same period of ~~2021. The change was primarily due to Centuri’s acquisition of Riggs Distler in 2021 (see~~ ~~Note 8 - Business Acquisitions~~).2022. The overall ~~decrease~~increase was driven by $1.02 billion in proceeds received in connection with the MountainWest sale (which is net of cash sold), including impacts of post-closing true-ups and commitments, partially offset by an increase in capital expenditures in ~~both~~ the natural gas distribution ~~and utility infrastructure services segments. The current period also included a post-closing payment of $18.8 million in association with the Mountain West acquisition.~~segment.

Financing Cash Flows. ~~Net cash provided by~~Cash flows from consolidated financing activities decreased ~~$1.1 billion~~$852 million in the first nine months of ~~2022~~2023 as compared to the same period of ~~2021.~~2022. The ~~change~~overall decrease was primarily due to ~~borrowings associated~~the first quarter 2023 repayment ($1.1 billion) of the then remaining balance of the term loan entered into by Southwest Gas Holdings, Inc. in November 2021 in connection with ~~Centuri’s~~the acquisition of Riggs Distler in 2021. The agreement provided for a $1.145 billion secured term loan facility and a $400 million secured revolving credit facility, which in addition to funding the Riggs Distler acquisition, refinanced Centuri’s previous $590 million loan facility.

Additionally contributing to the change were borrowings by Southwest, including the March 2021 Term Loan to initially finance a gas cost runup caused by the 2021 freeze event in and around the central U.S. due to Winter Storm Uri and the August 2021 issuance of $300 million in notes, as well as borrowings under the Company’s credit facility, offset by repayment of amounts under Southwest’s facility in 2021; by comparison, in the first nine months of 2022, financing activities were largely undertaken in concert with reductions in other borrowings. The Company reduced its 364-day Term Loan facility (utilized to finance the MountainWest acquisition) through netMountainWest. Other impacts included proceeds ~~of $452 million~~ from the issuance of common stock in an underwritten public ~~offering~~offerings in each period ($200 million lower than in the ~~current year. Proceeds~~2022 period), and proceeds from ~~other equity issuances by~~Southwest Gas Holdings entering into a $550 million Term Loan Credit Agreement in April 2023. A substantial portion of the ~~holding company were nominal in 2022 (and those in 2021~~term loan proceeds were contributed to ~~Southwest). Furthermore, while debt proceeds were received~~Southwest as equity, which in turn was primarily used by Southwest’s March 2022 issuance of $600 million in notes, it also redeemed, in February 2022, $25 million 7.78% series Medium-term notes then maturing, as well as $250 million in notes maturing in April 2022. Southwest ~~also repaid (during 2022) $25 million of amounts outstanding on the March 2021 Term Loan utilized~~to repay term loan indebtedness entered into to finance an escalation in purchased gas costs. Other financing cash flows include borrowings and repayments, including under the ~~gas cost runup in 2021, and paid down the balance existing at the time under its~~companies’ credit facility. The Company had higher borrowings under its credit facility in the current period given its expenditures for shareholder activism and settlement activities, along with the Strategic Review.

Dividends paid in 2022 were higher than during the comparative period in 2021.facilities.

The capital requirements and resources of the Company generally are determined independently for the individual business segments. Each business segment is generally responsible for securing its own debt financing sources. However, the holding company may raise funds through stock issuances or other external financing sources in support of each business segment.

Natural Gas Distribution Segment Construction Expenditures, Debt Maturities, and Financing

During the twelve-month period ended September 30, ~~2022,~~2023, construction expenditures for the natural gas distribution segment were ~~$672~~$778 million (not including amounts incurred for capital expenditures not yet paid). The majority of these expenditures, ~~represented costs~~approximately 55%, were associated with the replacement of existing transmission and distribution ~~and general plant~~pipeline facilities to fortify system integrity and ~~reliability.~~reliability, as well as other general plant expenditures, with the remainder related to new construction.

Management estimates natural gas segment construction expenditures during the ~~five-year~~three-year period ending December 31, ~~2026~~2025 will be approximately ~~$2.5 billion to $3.5~~$2.0 billion. Of this amount, approximately ~~$650~~$720 million to ~~$675~~$740 million is expected to be incurred during calendar year ~~2022.~~2023. Southwest plans to continue to request regulatory support to undertake projects, or to accelerate projects as necessary for the improvement of system flexibility and reliability, or to expand, where relevant, to unserved or underserved areas. Southwest may expand existing, or initiate new, programs. Significant replacement activities are expected to continue well beyond the next few years. See also Rates and Regulatory Proceedings. During the three-year period ending December 31, 2025, cash flows from operating activities of Southwest are expected to provide approximately ~~69%~~75% of the funding for gas operations of Southwest and total construction expenditures and dividend requirements. ~~As of September 30, 2022, Southwest had the March 2021 Term Loan with an outstanding balance of $225 million, due in March 2023. Any additional~~Additional cash requirements, including construction-related, and pay down or refinancing of debt, are expected to be provided by existing credit facilities, parent equity contributions, ~~from the Company,~~ and/or other external financing sources.

Liquidity

Several factors (some of which are out of the control of the Company) that could significantly affect liquidity in the future include: variability of natural gas prices, changes in ratemaking policies of regulatory commissions, regulatory lag, customer growth in the natural gas distribution segment, the ability to access and obtain capital from external sources, interest rates, changes in income tax laws, pension funding requirements, inflation, and the level of earnings. Natural gas prices and related gas cost recovery rates, as well as plant investment, have historically had the most significant impact on liquidity.

On an interim basis, Southwest defers over- or under-collections of gas costs to PGA balancing accounts. In addition, Southwest uses this mechanism to either refund amounts over-collected or recoup amounts under-collected as compared to the price paid for natural gas during the period since the last PGA rate change went into effect. At September 30, ~~2022,~~2023, the combined balance in the PGA accounts totaled an under-collection of $~~381~~687 million. See PGA Filings for more information.

~~In March 2022, Southwest amended the $250 million March 2021 Term Loan, extending the maturity date to March 21, 2023. As noted above, the proceeds were originally used to fund the increased cost~~ The market price of natural gas ~~supply during the month of February 2021 caused by extreme weather conditions in the central U.S. The March 2021 Term Loan was extended~~spiked as a result of numerous market forces including historically low storage levels, unexpected upstream pipeline maintenance events, and cold weather conditions across the ~~current~~western region in the latter part of 2022 and continuing into January 2023. As a result of this increase in pricing, in January 2023, Southwest entered into a 364-day $450 million term loan in order to fund the incremental cost. This indebtedness was repaid in April 2023 (refer to Note 5 – Debt in this Quarterly Report on Form 10-Q). We may be required to incur additional indebtedness in connection with future spikes in natural gas ~~cost environment and management’s funding plans for purchases. At September 30, 2022, there was $225 million outstanding under the March 2021 Term Loan.~~prices as a result of extreme weather events or otherwise.

~~Southwest Gas Holdings, Inc. has a credit facility with a borrowing capacity of~~ ~~$200 million~~ ~~that expires in December 2026. This facility is intended for short-term financing needs. At September 30, 2022,~~ ~~$156 million~~ ~~was outstanding under this facility.~~

~~In November 2021, the Company~~ entered into ~~a $1.6 billion delayed-draw Term Loan Facility that was funded on December 31,~~in November 2021 in connection with the acquisition of MountainWest. In March 2022, the Company used net proceeds from the issuance of common stock (see below) to repay a portion of borrowings under the Term Loan Facility. On September 26, 2022 (the “Amendment Date”), the Company entered into Amendment No. 1 to the Term Loan Facility. The Amendment, among other things, (1) extended the maturity date of the Term Loan to December 30, 2023, and (2) replaced LIBOR interest rate benchmarks with SOFR interest rate benchmarks. There was $1.15 billion outstanding under this Term Loan Facility as of September 30, 2022. As part of the Amendment, the Company paid a non-refundable upfront fee in an amount equal to 0.10% of the aggregate principal amount outstanding as of the Amendment Date, and will pay additional fees based on any principal balance outstanding on March 31, 2023, June 30, 2023, and September 30, 2023 of 0.10%, 0.15%, and 0.20%, respectively. Management intends to pay off the remainder of the Term Loan Facility through the issuance of long-term debt or equity securities or using the proceeds from a sale of MountainWest and/or Centuri. Management maintains the discretion to seek alternative sources, and can provide no assurances as to its ability to refinance this obligation with the intended method or on attractive terms.

In March ~~2022,~~2023, the Company ~~sold,~~issued through a separate prospectus supplement under ~~its~~the Universal Shelf, ~~program,~~ an aggregate of ~~6.325~~4.1 million shares of common stock, ~~with~~at an underwritten public offering price of ~~$74.00~~$60.12 per share, resulting in net proceeds to the Company of ~~$452.2~~$238.4 million, net of ~~the underwriters’~~an underwriter’s discount of ~~$15.8 million.~~$8.3 million and estimated expenses of the offering.

In April 2021, the Company entered into a Sales Agency Agreement between the Company and BNY Mellon Capital Markets, LLC and J.P. Morgan Securities LLC (the “Equity Shelf Program”) for the offer and sale of up to $500 million of common stock from time to time in at-the-market offerings under the related prospectus supplement filed with the ~~Securities and Exchange Commission (the “SEC”) the same month.~~SEC. There ~~was~~ was no activity under this multi-year program during the third quarter of ~~2022.~~2023. Net proceeds from the ~~sales~~sale of shares of common stock under the Equity Shelf Program are intended for general corporate purposes, including the acquisition of property for the construction, completion, extension, or improvement of pipeline systems and facilities located in and around the communities served by Southwest, as well as for repayment or repurchase of indebtedness (including amounts outstanding from time to time under the credit facilities, senior notes, ~~Term Loan~~ or ~~future credit facilities)~~other indebtedness), and to provide for working capital. The Company had approximately $341.8 million available under the program as of September 30, ~~2022.~~2023. See Note 4 – Common Stock for more information.

Interest rates for Centuri’s term loan contain LIBOR-based rates. Certain LIBOR-based rates were discontinued as a benchmark or reference rate after 2021, while other LIBOR-based rates are scheduled to be discontinued after June 2023. As of September 30, 2022, the Company had $1.009 billion in aggregate outstanding borrowings under Centuri’s term loan facility. In order to mitigate the impact of a LIBOR discontinuance on the Company’s financial condition and results of operations, management will monitor developments and work with lenders, where relevant, to determine the appropriate replacement/alternative reference rate for variable rate debt. At this time the Company can provide no assurances as to the impact a LIBOR discontinuance will have on its financial condition or results of operations. Any alternative rate may be less predictable or less attractive than LIBOR.

In addition, the Company can provide no assurance that its discussions regarding certain trends or plans relating to its financing and operating expenses will continue, proceed as planned, or cease to continue, or fail to be alleviated, in future periods. For additional information on the risks associated with the Company’s business, see Item 1A. Risk Factors and Item 7A. Quantitative and Qualitative Disclosures About Market Risk in the Annual Report on Form 10-K for the year ended December 31, ~~2021, and as updated in quarterly reports, including in association with this Quarterly Report on Form 10-Q.~~2022.

All forward-looking statements in this quarterly report are made as of the date hereof, based on information available to the Company and Southwest as of the date hereof, and the Company and Southwest assume no obligation to update or revise any of its forward-looking statements, even if experience or future changes show that the indicated results or events will not be realized. We caution you not to unduly rely on any forward-looking statement(s).

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

See Item 7A. Quantitative and Qualitative Disclosures about Market Risk in the ~~2021~~2022 Annual Report on Form 10-K filed with the SEC. No material changes have occurred related to the disclosures about market risk.

ITEM 4. CONTROLS AND PROCEDURES

Management of Southwest Gas Holdings, Inc. and Southwest Gas Corporation has established disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) that are designed to provide reasonable assurance that information required to be disclosed in their respective reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and to provide reasonable assurance that such information is accumulated and communicated to management of each company, including each respective Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and benefits of controls must be considered relative to their costs. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or management override of the control. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and may not be detected.

Based on the most recent evaluation, as of September 30, ~~2022,~~2023, management of Southwest Gas Holdings, Inc. and Southwest Gas Corporation, including the Chief Executive Officer and Chief Financial Officer, believes the Company’s and Southwest’s disclosure controls and procedures are effective at attaining the level of reasonable assurance noted above.

There have been no changes in the Company’s or Southwest’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during the third quarter of ~~2022~~2023 that have materially affected, or are likely to materially affect the Company’s internal control over financial reporting.

PART II - OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

The Company and Southwest are named as ~~a defendant~~defendants in various legal proceedings. The ultimate dispositions of these proceedings are not presently determinable; however, it is the opinion of management that none of ~~this litigation~~these legal proceedings individually or in the aggregate will have a material adverse impact on the Company’s or Southwest’s financial position or results of operations. ~~See~~ ~~Contingency~~ ~~withinNote 1 – Background, Organization, and Summary of Significant Accounting Policies~~ ~~for ongoing and dismissed litigation, including litigation filed by certain stockholders and by funds managed by Carl C. Icahn.~~

ITEM 1A. RISK FACTORS

Described below is a risk factor ~~that~~ we have identified that may have a negative impact on our future financial performance or affect whether we achieve the goals or expectations expressed or implied in any forward-looking statements contained herein. This risk factor supplements, ~~and~~but does not replace, the Risk Factors and other disclosures made in our Annual Report on Form 10-K filed ~~March 1, 2022 and~~February 28, 2023 or in our Quarterly Reports on Form 10-Q filed May ~~10, 2022~~9, 2023 and August 9, ~~2022.~~2023.

~~Operational Risks~~

~~Certain~~Our options for separating Centuri may be limited by market conditions and tax considerations.Any separation transaction of ~~our costs, such as operating expenses (including labor, fuel,~~Centuri may not occur on the anticipated timeline and ~~materials) at Southwest, Centuri, and MountainWest, and interest and general and administrative expenses at all three segments and~~may not have the ~~Company could be adversely impacted by periods of heightened inflation, which could have an adverse impact on our results of operations.~~anticipated benefits.

~~SOUTHWEST GAS HOLDINGS, INC.~~						~~Form 10-Q~~
~~SOUTHWEST GAS CORPORATION~~						~~September 30, 2022~~

~~In recent months,~~On December 15, 2022, we announced our intention to pursue a spin-off of Centuri into an independent publicly-traded company, subject to the ~~consumer price index has increased substantially~~satisfaction of certain conditions, including receipt of favorable rulings from the IRS and ~~may~~receipt of other regulatory approvals. On September 22, 2023, we announced that Centuri Holdings had confidentially submitted a draft registration statement with respect to an initial public offering of its shares of common stock (the “Centuri IPO”). On November 6, 2023, we announced that the IRS had advised us that it had exercised its discretion not to rule on certain tax questions related to a potential spin-off of Centuri due to the fact-intensive nature of the questions presented. We remain committed to separating Centuri and continue to ~~remain at elevated levels~~assess the value of a potential tax-free spin-off of Centuri, either following, or in lieu of, a potential initial public offering by Centuri. Following a Centuri IPO, if one occurs, we intend to maintain the flexibility to dispose of our interests in a number of ways, including through a spin-off transaction, open market sales of Centuri Holdings common stock or an exchange offer of our common stock for ~~an extended period~~Centuri Holdings common stock.

A Centuri IPO may not occur for a number of ~~time. Federal policies~~reasons, including, but not limited to, adverse market conditions, negative investor feedback or declines in business performance.If the Centuri IPO does not occur, our options for separating Centuri will be limited, and ~~recent global events,~~we may be forced to pursue a spin-off of Centuri even if such spin-off may be taxable to us.

While we intend that any spin-off transaction, if effected, will qualify as a tax-free transaction to our stockholders, the ~~volatility in prices~~ability to effect a tax-free spin-off to the Company (as opposed to our stockholders) could be lost if a 355 Ownership Change occurs within applicable time periods for purposes of ~~oil~~Section 355(e) of the Internal Revenue Code. We have taken certain actions, including the adoption of the Plan, to help preserve the tax-free nature of any spin-off transaction. However, we can provide no assurance that such actions will ultimately permit us to complete a spin-off that is tax-free to us or that our existing net operating losses will fully offset the impact of any spin-off that is taxable to us.

In addition, if we pursue a spin-off of Centuri without a Centuri IPO, we or Centuri may not realize any cash proceeds from a separation, which may cause us to pay transaction expenses and ~~natural gas,~~taxes, if applicable, out of cash on hand, to the extent available, or to incur additional indebtedness, and ~~the conflict between Russia and Ukraine, may have exacerbated, and may~~would likely cause Centuri to continue to ~~exacerbate, increases in the consumer price index. In addition, during periods of rising inflation, variable interest rates and the interest rates of any debt securities~~have significant outstanding indebtedness. If we ~~Southwest, MountainWest,~~are required to seek additional third-party financing either for us or for Centuri issue will likely be higher than more recent debt issuances, which will further tend to reduce returns to our stockholders. A sustained or further increase in inflation could have a material adverse impact on our operating expenses incurred in connection with ~~among others,~~a spin-off, it may delay the ~~cost~~timing of ~~natural gas supply, labor, products,~~the transaction.

Executing the proposed separation also requires significant time and ~~services required for operations, maintenance~~attention from management, which could distract them from other tasks in operating our business and ~~capital improvements at Southwest~~disrupt our operations. We cannot provide assurances that the Centuri IPO and ~~MountainWest,~~the other transactions described above, if consummated, will yield greater net benefits to the Company and ~~fuel, labor, and materials costs at~~its shareholders than if the Centuri ~~as well as general administrative expenses for all three segments.~~

With regard to Southwest, rate schedules in each of its service territories contain purchased gas adjustment clauses which permit Southwest to file for rate adjustments to recover increases in the cost of purchased gas. Increases in the cost of purchased gas have no direct impact on our profit margins but do affect cash flows and can therefore impact the amount of our capital resources. In order to help cope with the effects of inflation on its operations, Southwest may file requests for rate increases to cover the increased cost of purchased gas IPO and/or other ~~types~~transactions described above had not occurred. If we fail to achieve some or all of ~~expenditures noted above. However, there can be no assurance that Southwest will be able~~the benefits expected to ~~obtain adequate and timely rate relief to offset~~result from the effects of inflation and any non-recovery of costs or regulatory lag will reduce our cash flows and earnings. As a result, during inflationary periods in which the inflation rate exceeds the rate increases applicable to purchased gas, Centuri IPO and/or other ~~types of expenditures, we may not adequately mitigate the impact of inflation, which may adversely affect~~potential separation transactions described above, or if such benefits are delayed, our business, operating results and financial condition ~~results of operations, and cash flows.~~

Additionally, inflationary pricing has had and may continue to have a negative effect on the construction costs necessary to complete projects at Centuri, particularly with respect to fuel, labor, and materials costs discussed above. Centuri is experiencing pressures on fuel, materials, and certain labor costs as a result of the inflationary environment and current general labor shortage, which has resulted in increased competition for skilled labor and wage inflation. Centuri has not been able to, and may not be able to, fully adjust its contract pricing to compensate for these cost increases, which has affected, and may continue to affect, Centuri’s profitability and cash flows. Inflationary pressures and related recessionary concerns in light of governmental and central bank efforts to mitigate inflation could also cause uncertainty for Centuri’s customers and affect the level of their project activity, which could also adversely affect Centuri’s profitability and cash flows.

As inflation persists, the Federal Reserve has and may continue to raise benchmark interest rates, which likely will cause our borrowing costs to increase over time. As a result of the inflationary factors discussed above affecting the Company, Southwest, MountainWest, and Centuri, our business, financial condition, results of operations, cash flows, and liquidity could be materially and adversely ~~affected over time.~~affected.

~~ITEMS~~ITEM 2through 3. None.

ITEM 4. MINE SAFETY DISCLOSURES Not applicable.

ITEM 5. OTHER INFORMATION ~~None.~~

During the fiscal quarter ended September 30, 2023, none of our directors or Section 16 officers informed us of the adoption or termination of a “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement,” as those terms are defined in Regulation S-K, Item 408.
