SOUTHWEST GAS CORPORATION  March 31, 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” 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”). Additionally, the Company determined it will pursue a spin-off of Centuri (the “Centuri spin-off”), to form a new independent publicly traded utility infrastructure services company. The MountainWest sale closed on February 14, 2023. The Centuri spin-off is expected to be completed in the fourth quarter of 2023 or the first quarter of 2024 and to be tax free to the Company and its stockholders for U.S. federal income tax purposes. 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.
Centuri is a strategic utility infrastructure services company dedicated to partnering with North America’s gas and electric providers to build and maintain the energy network that powers millions of homes across the United States (“U.S.”) and Canada. Centuri derives revenue primarily from installation, replacement, repair, and maintenance of energy networks. Centuri operates in the U.S., primarily as NPL, Neuco, Linetec, and Riggs Distler, and in Canada, primarily as NPL Canada. Utility infrastructure services activity is seasonal in many of Centuri’s operating areas. Peak periods are the summer and fall months in colder climate areas, such as the northeastern and midwestern U.S. and in Canada. In warmer climate areas, such as the southwestern and southeastern U.S., utility infrastructure services activity continues year round.
Basis of Presentation. The condensed consolidated financial statements of Southwest Gas Holdings, Inc. and subsidiaries and Southwest (with its subsidiaries) included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). The year-end 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, other than the sale of MountainWest, discussed above.
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 the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. In the opinion of management, all adjustments, consisting of normal recurring items and estimates necessary for a fair statement of results for the interim periods, have been made.
These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the 2022 Annual Report to Stockholders, which is incorporated by reference into the 2022 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.

Other Property and Investments. Other property and investments on Southwest’s and the Company’s Condensed Consolidated Balance Sheets includes:

Total Southwest Gas Holdings, Inc.$1,250,327 $1,281,172 
Included in the table above are the net cash surrender values of company-owned life insurance (“COLI”) policies. These life insurance policies on members of management and other key employees are used by Southwest to indemnify itself against the loss of talent, expertise, and knowledge, as well as to provide indirect funding for certain nonqualified benefit plans. The term non-regulated in regard to assets and related balances in the table above is in reference to the non-rate regulated operations of Centuri.
Held for sale. The Company and Southwest have classified certain assets associated with its previous corporate headquarters as held for sale during the first quarter of 2023. An agreement for sale was signed in May 2023, subject to certain closing conditions, including possible extension periods. Amounts to be realized above the carrying value are not expected to be material to the financial statements overall. Management determined that the assets met the criteria to be classified as held for sale as of March 31, 2023. As a result, the Company and Southwest reclassified approximately $27 million from Other property and investments to current assets held for sale on their respective Condensed Consolidated Balance Sheets at March 31, 2023.
Cash and Cash Equivalents.  Cash and cash equivalents of the Company include $32.7 million and $30 million of money market fund investments at March 31, 2023 and December 31, 2022, respectively. The money market fund investments for Southwest were $29.6 million at March 31, 2023 and $17.6 million at December 31, 2022, respectively. These investments fall within Level 2 of the fair value hierarchy, due to the asset valuation methods used by money market funds.
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 $37.3 million and $34.2 million during the three months ended March 31, 2023, respectively, and increased $5.5 million and $5.7 million during the twelve months ended March 31, 2023, respectively.
Accounts Receivable, net 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 that are receivable at the end of any reporting date may not be collected, 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 rate-regulated companies to adjust billing rates for changes in the cost of natural gas purchased. The difference between the current cost of gas purchased and the cost of gas recovered in billed rates is deferred. Generally, these deferred amounts are recovered or refunded within one year.
Prepaid and other current assets. Prepaid and other current assets for Southwest include, among other things, materials and operating supplies of $79 million at March 31, 2023 and $77.3 million at December 31, 2022 (carried at weighted average cost). Also included in the balance was $207 million as of December 31, 2022 in accrued purchased gas cost, with no corresponding asset balance as of March 31, 2023.
Goodwill. Goodwill is assessed as of October 1st each year for impairment, or more frequently, if circumstances indicate it may be more likely than not that the fair value of a reporting unit is less than its carrying value. The Company’s reporting units for goodwill are its operating segments, which are also its reportable segments. Since December 31, 2022, management qualitatively assessed whether events during the first three months of 2023 indicated it was more likely than not that the fair value of our reporting units was less than their carrying value, which if the case, could be an indication of a goodwill impairment. Through management’s assessments during first quarter of 2023, no impairment was deemed to have occurred in the continuing segments of the Company. However, there can be no assurances that future assessments of goodwill will not
14

result in an impairment, and various factors, including changes 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 the fair value of reporting units being lower than their carrying values. Goodwill in the Natural Gas Distribution and Utility Infrastructure Services segments is included in their respective Condensed Consolidated Balance Sheets as follows:

Other Current Liabilities. Management recognizes in its balance sheets various liabilities that are expected to be settled through future cash payment within the next twelve months, including amounts payable under regulatory mechanisms, customary accrued expenses for employee compensation and benefits, declared but unpaid dividends, and miscellaneous other accrued liabilities. Other current liabilities for the Company include $44.2 million and $41.6 million of dividends declared as of March 31, 2023 and December 31, 2022, respectively. Also included in the balance was $68 million as of March 31, 2023 in accrued purchased gas cost, with no corresponding liability balance as of December 31, 2022.

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. Interest income includes carrying charges on regulatory account balances, including deferred purchased gas cost balances, which increased from $368 million as of March 31, 2022 to $970 million as of March 31, 2023. Refer also to Note 2 – Components of Net Periodic Benefit Cost.
Redeemable Noncontrolling Interests. In connection with the acquisition of Linetec in November 2018, the previous owner initially retained a 20% equity interest in that entity, with redemption being subject to certain rights based on the passage of time or upon the occurrence of certain triggering events. Effective in 2022, the Company, through Centuri, had the right, but not the obligation, to purchase at fair value (subject to a floor) a portion of the interest held by the previous owner, and in incremental amounts each year thereafter. In March 2022, the parties agreed to a partial redemption, reducing the noncontrolling interest to 15%, and in March 2023, agreeing once again to a 5% redemption (of the 15% then remaining), and to thereby reduce the noncontrolling interest to 10% under the terms of the original agreement. As a result of this most recent election, Centuri accrued $39.9 million as of March 31, 2023, which was paid to the previous owner of Linetec in April 2023. The impact of this transaction has been excluded from the Company’s Condensed Consolidated Statement of Cash Flows for
15

SOUTHWEST GAS HOLDINGS, INC.  Form 10-Q
SOUTHWEST GAS CORPORATION  March 31, 2023

2023 due to its noncash nature in advance of the April 2023 payment. The remaining balance continuing to be redeemable as of March 31, 2023 is 10% under the terms of the original agreement, with Centuri now owning a 90% stake in Linetec.
Certain members of Riggs Distler management have a 1.42% interest in Drum, which is redeemable, subject to certain rights based on the passage of time or upon the occurrence of certain triggering events.
Significant changes in the value of the redeemable noncontrolling interests, above a floor determined at the establishment date, are recognized as they occur, and the carrying value is adjusted as necessary at each reporting date. The fair value is estimated using a market approach that utilizes certain financial metrics from guideline public companies of similar industry and operating characteristics. Based on the fair value model employed, the estimated redemption value of the Linetec redeemable noncontrolling interest increased approximately $5.8 million during the three months ended March 31, 2023, notwithstanding the change resulting from the partial redemption noted above. Valuation adjustments also impact retained earnings, as reflected in the Company’s Condensed Consolidated Statement of Equity, but do not impact net income. The following depicts changes to the balances of the redeemable noncontrolling interests:

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:

(1) The number of anti-dilutive restricted stock units excluded from the calculation of diluted shares during the twelve months ended March 31, 2023 is 166,000.
(2) The number of securities included 132,000 and 112,000 performance shares during the three months ended March 31, 2023 and 2022, and 149,000 and 114,000 performance shares during the twelve months ended March 31, 2023 and 2022, respectively, the total of which was derived by assuming that target performance will be achieved during the relevant performance period.

Income Taxes. The Company’s effective tax rate was 37.6% for the three months ended March 31, 2023, compared to 19.9% for the corresponding period in 2022. The effective tax rate increase was primarily due to the MountainWest sale, and includes the impact of book versus tax basis differences related to the transaction (See Note 8 - Dispositions).
Southwest’s effective tax rate was 18.3% for the three months ended March 31, 2023, compared to 20.6% in the prior year quarter. These amounts varied from the statutory rate primarily as the result of the amortization of excess deferred income taxes.
In April 2023, the Internal Revenue Service (“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 transmission and distribution property must be capitalized for tax purposes. The Company and Southwest are currently reviewing this revenue procedure to determine the potential impact on their financial position, results of operations, and cash flows.

Recent Accounting Standards Updates.
Accounting pronouncements effective or adopted in 2023:
In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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 the topic) to replace a reference rate affected by reference rate reform. The update applies only to contracts and hedging relationships that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued due to reference rate reform. In December 2022, the FASB issued ASU 2022-06 “Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848.” The update provides deferral of the sunset date of Topic 848 from December 31, 2022 to December 31, 2024. Management will continue to 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. See also LIBOR discussion in Note 5 – Debt.
There are no other recently issued accounting standards updates that are expected to be adopted or material to Southwest or the Company effective in 2023 or thereafter.

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

item was not material to the previously issued financial statements and revised the disclosures for the three- and twelve- months ended March 31, 2022.
The following table provides information about contracts receivable and revenue earned on contracts in progress in excess of billings (contract assets), both of which are included within Accounts receivable, net of allowances, as well as amounts billed in excess of revenue earned on contracts (contract liabilities), which are included in Other current liabilities as of March 31, 2023 and December 31, 2022 on the Company’s Condensed Consolidated Balance Sheets:

Revenue earned on contracts in progress in excess of billings279,624 238,059 
Amounts billed in excess of revenue earned on contracts39,595 35,769 
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. 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, 2022 to March 31, 2023 increased due to amounts received for services not yet performed, net of revenue 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 March 31, 2023, Centuri had 62 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 March 31, 2023 was $458.2 million. Centuri expects to recognize the remaining performance obligations over approximately the next two years; however, the timing of that recognition is largely within the control of the customer, including when the necessary materials required to complete the work are provided by the customer.

Note 4 – Common Stock
Shares of the Company’s common stock are publicly traded on the New York Stock Exchange, under the ticker symbol “SWX.” Share-based compensation related to Southwest and Centuri is based on stock awards to be issued in shares of Southwest Gas Holdings, Inc.
On April 8, 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 an at-the-market offering program. The shares are issued pursuant to the Company’s automatic shelf registration statement on Form S-3 (File No. 333-251074), or “the Universal Shelf.” There was no activity under the Equity Shelf Program during the quarter ended March 31, 2023. The following table provides the life-to-date activity under that program through March 31, 2023:
Gross proceeds$158,180,343 
Less: agent commissions(1,581,803)
Net proceeds$156,598,540 
Number of shares sold2,302,407 
Weighted average price per share$68.70 
As of March 31, 2023, the Company had approximately $342 million in common stock available for sale under the program.
In March 2023, the Company issued, through a separate prospectus supplement under the Universal Shelf, an aggregate of 4.1 million shares of common stock, at an underwritten public offering price of $60.12 per share, resulting in net proceeds to the Company of $238.4 million, net of an underwriter’s discount of $8.3 million and estimated expenses of the offering. Approximately $140 million (2.3 million shares) of the offering was purchased by certain funds affiliated with Carl C. Icahn, a significant stockholder beneficially owning more that 10% of the outstanding stock of the Company. The Company used the net proceeds to repay outstanding amounts under the Company’s credit facility, with the remaining proceeds used to pay off residual amounts outstanding under the loan entered into in November 2021 in connection with the acquisition of MountainWest and the remainder, for working capital and general corporate purposes.
During the three months ended March 31, 2023, the Company issued approximately 54,000 shares of common stock through the Restricted Stock/Unit Plan and Omnibus Incentive Plan.
Additionally, during the three months ended March 31, 2023, the Company issued 46,000 shares of common stock through the Dividend Reinvestment and Stock Purchase Plan, raising approximately $2.7 million.

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 March 31, 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 March 31, 2023, no borrowings were outstanding on the long-term portion (including under the commercial paper program), nor under the short-term portion of the facility.
Centuri has a $1.545 billion secured revolving credit and term loan multi-currency facility. Amounts can be borrowed in either Canadian or U.S. dollars. The revolving credit facility matures on August 27, 2026 and the term loan facility matures on August 27, 2028. Interest rates for the revolving credit facility are based on SOFR, plus an applicable margin; the term loan facility is based on LIBOR, plus an applicable margin. The capacity of the line of credit portion of the facility is $400 million; related amounts borrowed and repaid are available to be re-borrowed. The term loan portion of the facility has a limit of $1.145 billion. The obligations under the credit agreement are secured by present and future ownership interests in substantially all direct and indirect subsidiaries of Centuri, substantially all of the tangible and intangible personal property of each borrower, certain of their direct and indirect subsidiaries, and all products, profits, and proceeds of the foregoing. Centuri’s assets securing the facility at March 31, 2023 totaled $2.4 billion. At March 31, 2023, $1.022 billion in borrowings were outstanding under Centuri’s combined secured revolving credit and term loan facility.
In March 2023, Southwest issued $300 million aggregate principal amount of 5.450% Senior Notes (the “March 2023 Notes”). The notes will mature in March 2028. Southwest used the net proceeds to repay amounts outstanding under its credit facility and the remainder for general corporate purposes.
In April 2023, Southwest Gas Holdings, Inc. entered into a $550 million Term Loan Credit Agreement that matures in October 2024. Southwest Gas Holdings, Inc. utilized a majority of the 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 $450 million 364-day term loan entered into in January 2023 (discussed below), with the remainder of the equity contribution used for working capital and general corporate purposes.
Short-Term Debt
Southwest Gas Holdings, Inc. has a $300 million credit facility that is scheduled to expire in December 2026 and is primarily used for short-term financing needs. Interest rates for the credit facility are calculated at either SOFR or the “alternate base rate,” plus in each case an applicable margin. There was $18 million outstanding under this credit facility as of March 31, 2023.
As indicated above, under Southwest’s $400 million credit facility, no short-term borrowings were outstanding at March 31, 2023.
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. During the first quarter of 2023, the March 2021 Term Loan was repaid in full by use of Southwest’s credit facility, prior to the issuance of the March 2023 Notes, proceeds from which were used to pay down indebtedness then outstanding under the credit facility, as indicated.
On September 26, 2022, Southwest Gas Holdings, Inc. entered into Amendment No. 1 to the 364-day Term Loan Credit Agreement, initially borrowed to fund the acquisition of the equity interests in MountainWest, of which $1.147 billion was outstanding as of December 31, 2022. The Credit Agreement initially provided for a $1.6 billion delayed-draw term loan (the “Term Loan Facility”). In connection with the close of the MountainWest sale on February 14, 2023, $1.075 billion of the proceeds were used to pay down the Term Loan Facility. During the first quarter of 2023, the Company paid down the remaining balance of the Term Loan Facility of approximately $72 million.
In January 2023, Southwest entered into a 364-day $450 million term loan agreement. Southwest initially used the proceeds to fund higher than expected natural gas costs for the November 2022 through March 2023 winter period, caused by numerous market forces, including historically low storage levels, unexpected upstream pipeline maintenance events, and cold weather conditions across the western region. As indicated above, the term loan was repaid in full on April 17, 2023.

The corporate and administrative activities for Southwest Gas Holdings, Inc. in the three-month period ended March 31, 2023 include, among other things, additional amounts related to commitments under the sale agreement with Williams in regard to MountainWest, including a charge of $28.4 million from the post-closing rate case settlement agreement for MountainWest Overthrust Pipeline (pending Federal Energy Regulatory Commission (the “FERC” approval)); and an additional $21 million
26


reflects the final accrued post-closing payment of $7.4 million related to cash and net working capital balances above/below a contract benchmark, with the remaining charge associated with other changes in the assets and liabilities that were not subject to post-closing payment true-up provisions. The post-closing payment of $7.4 million will effectively return approximately the same amount initially paid by Williams to the Company at closing. Other corporate and administrative amounts during this same quarter also reflect residual costs associated with or as a result of the MountainWest sale, as well as $12 million of interest expense, primarily under the loan entered into by Southwest Gas Holdings, Inc. in November 2021 in connection with the acquisition of MountainWest prior to it being paid in full in March 2023 (including $2.5 million in debt issuance costs written off when the debt was repaid). The twelve-month period ended March 31, 2023 included more than $47 million of interest expense under the aforementioned MountainWest acquisition loan, the other items noted above, as well as $35 million in combined costs associated with stockholder activism and the associated proxy contest, the May 2022 settlement with the Icahn group, and costs of a strategic review initiative initiated in 2022. The amounts related to the MountainWest sale, including the rate case settlement, and post-closing adjustments, are included in Goodwill impairment and loss on sale on the Company’s Condensed Consolidated Statement of Income.
Note 8 - Dispositions
Dispositions
In December 2022, the Company announced that the Board unanimously determined to take strategic actions to simplify the Company’s portfolio of businesses. These actions included entering into a definitive agreement to sell 100% of MountainWest to Williams for $1.5 billion in total enterprise value, subject to certain adjustments. The MountainWest sale closed on February 14, 2023. The Company is expected to provide certain services to Williams under a transition services agreement for a brief period, generally not beyond six months from the sale closing date. Additionally, the Company determined it will pursue a spin-off of Centuri to form a new independent publicly traded utility infrastructure services company. The Centuri spin-off is currently expected to be completed by the fourth quarter of 2023 or the end of the first quarter of 2024 and to be tax free to the Company and its stockholders for U.S. federal income tax purposes. The separation of Centuri will be subject to, among other things, finalizing the transaction structure, final approval by the Board, approval by the Arizona Corporation Commission (the “ACC”), the receipt of a favorable private letter ruling by the IRS relating to the tax-free nature of the transaction, and the effectiveness of a registration statement to be filed with the SEC. The application for the private letter ruling was filed with the IRS in March 2023 and the application to the ACC was filed in April 2023.
The fair value of the MountainWest assets held-for-sale was previously estimated based on the preliminary closing statement and subject to certain adjustments, including a post-closing payment between the parties related to final working capital balances. The amount of the post-closing payment was finalized in May 2023, prior to the issuance of these financial statements. The Company recognized an additional loss on 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 net working capital balances above/below a contractual benchmark, with the remaining charge associated with other changes in the assets and liabilities that were not subject to post-closing payment true-up provisions. The post-closing payment of $7.4 million will effectively return approximately the same amount initially paid by Williams to the Company at closing.
As referred to in Note 7 – Segment Information, on September 22, 2022, the FERC issued an order initiating an investigation, pursuant to section 5 of the Natural Gas Act, to determine whether rates charged by MountainWest Overthrust Pipeline, LLC, a subsidiary of MountainWest, were just and reasonable and setting the matter for hearing (the “Section 5 Rate Case”). Unless earlier settled by the parties, a hearing on the matter was to commence on August 1, 2023 with an initial decision from the presiding administrative law judge due by November 14, 2023. Under the terms of the purchase and sale agreement entered into in connection with the MountainWest sale, the Company is obligated, for a period of four years following the closing of the MountainWest sale, to indemnify Williams and MountainWest for any damages and liabilities resulting from the Section 5 Rate Case, including any reduction to the current applicable rate, up to a cap of $75 million. Williams agreed not to enter into any settlement of the Section 5 Rate Case that would result in damages being paid by the Company under the indemnity arrangement without prior written consent of the Company. In March 2023, the parties agreed to a settlement, which is pending approval by the FERC. As a result, the Company recorded an additional estimated loss of $28.4 million from the disposal of MountainWest in the first quarter of 2023, which is included in Goodwill impairment and loss on sale in the Company’s Condensed Consolidated Statement of Income. Other contingent commitments were part of the agreement as well, which are currently expected to be immaterial.

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), 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 common stock of 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.”
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 in an all-cash transaction 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. Additionally, the Company determined it will pursue a spin-off of Centuri (the “Centuri spin-off”), to form a new independent publicly traded utility infrastructure services company. The Centuri spin-off is currently expected to be completed in the fourth quarter of 2023 or the first quarter of 2024 and to be tax free to the Company and its stockholders for U.S. federal income tax purposes. The Centuri spin-off will be subject to, among other things, finalizing the transaction structure, final approval by the Board, approval by the Arizona Corporation Commission (the “ACC”), the receipt of a favorable Internal Revenue Service (“IRS”) private letter ruling relating to the tax-free nature of the transaction, and the effectiveness of a registration statement that will be filed with the U.S. Securities and Exchange Commission (the “SEC”). The application for the private letter ruling was filed with the IRS in March 2023 and the application to the ACC was filed in April 2023. 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. 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 Southwest’s service territories.
As of March 31, 2023, Southwest had 2,206,000 residential, commercial, industrial, and other natural gas customers, of which 1,182,000 customers were located in Arizona, 819,000 in Nevada, and 205,000 in California. Over the past twelve months, first-time meter sets were approximately 42,000, compared to 38,000 for the twelve months ended March 2022. Residential and small commercial customers represented over 99% of the total customer base. During the twelve months ended March 31, 2023, 54% of operating margin (Regulated operations revenues less the net cost of gas sold) was earned in Arizona, 35% in Nevada, and 11% in California. During this same period, Southwest earned 84% of its operating margin from residential and small commercial customers, 5% from other sales customers, and 11% from transportation customers. These patterns are expected to remain materially consistent for the 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 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
28


operates in 83 primary locations across 45 states and provinces in the U.S. and Canada. 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 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, which was sold on February 14, 2023, is an interstate natural gas transmission pipeline company that provides transportation and underground storage services to customers in Utah, Wyoming, and Colorado. During the period of ownership by the Company, its operations included a substantial portion of its revenue being derived from reservation charges, with variable rates also included as part of its primarily rate-regulated rate structures.
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.

Results from natural gas distribution operations improved $23 million between the first quarters of 2023 and 2022. The improvement was primarily due to an increase in Operating margin and Other income (deductions), offset by an increase in Operations and maintenance, Depreciation and amortization, and Net interest deductions.
Operating margin increased $34.3 million quarter over quarter. Approximately $5 million of incremental margin was attributable to customer growth, including 42,000 first-time meter sets during the last twelve months. Combined rate relief added approximately $14 million of combined margin. Amounts collected from customers associated with previously unrecovered Vintage Steel Pipe (“VSP”) and Customer-Owned Yard Line (“COYL”) programs in Arizona ($4 million) also contributed to the improvement. Additionally, an $8 million out-of-period adjusting entry in the current quarter was made, which reduced Net cost of gas sold (See Basis of Presentation in Note 1 – Background, Organization, and Summary of Significant Accounting Policies in this Quarterly Report on Form 10-Q). Other differences include customer-provided fuel required for pipeline operations (offset in Operations and maintenance expense), and miscellaneous revenue and margin from customers outside the decoupling mechanisms.
Operations and maintenance expense increased $11.6 million between quarters, including approximately $4 million in fuel-related costs ($3 million of which is customer-provided fuel for pipeline operations, discussed above), $1.7 million in combined leak survey and line locating costs, $2.6 million primarily related to outside services/contractor costs in various areas of the business, as well as increases in insurance related claims ($1 million).
Depreciation and amortization expense increased $2.5 million, or 4%, between quarters, primarily due to a $533 million, or 6%, increase in average gas plant in service since the corresponding first quarter of 2022, offset by $647,000 in reduced amortization expense related to regulatory account balances. The increase in plant was attributable to pipeline capacity reinforcement work, franchise requirements, scheduled pipe replacement activities, and new infrastructure.
Other income increased $17 million. Interest income increased $9.7 million between quarters related to carrying charges associated with regulatory account balances, notably deferred purchased gas cost balances, which increased from $368 million existing as of March 31, 2022 to $970 million existing as of March 31, 2023. The non-service-related components of employee pension and other postretirement benefit costs decreased $5.3 million between quarters. Southwest also recognized a $4.4 million increase in COLI results in the current quarter compared to the comparable quarter in the prior year.
Net interest deductions increased $12 million in the first quarter of 2023, as compared to the prior-year quarter, primarily due to interest associated with $600 million of Senior Notes issued in March 2022, $300 million of Senior Notes issued in December 2022, and $300 million of Senior Notes issued in March 2023. Additionally, increased interest resulted from an increase in short-term debt, including a $450 million term loan issued in January 2023 (paid off in full in April 2023).

Contribution to consolidated results$177,281 $180,215 
Contribution to consolidated net income from natural gas distribution operations decreased approximately $3 million between the twelve-month periods ended March 2023 and 2022. The decline was due primarily to increases in Operations and maintenance expense, Depreciation and amortization, and Net interest deductions, offset by an increase in Operating margin and Other income.
Operating margin increased $76 million between periods. Customer growth provided $15 million, and combined rate relief provided $27 million of incremental operating margin. Also contributing to the increase were customer late fees that were $2.4 million greater in the current period due to lifting the earlier moratorium on such fees in all jurisdictions. Approved VSP and COYL revenue in Arizona also contributed to the improvement between periods ($21 million). The $8 million out-of-period adjustment to Net cost of gas sold, noted earlier, also contributed to the increase. Offsetting these increases were lower recoveries associated with regulatory account balances ($4 million); an associated comparable decrease is also reflected in amortization expense between periods (discussed below).
Operations and maintenance expense increased $51 million between periods. In addition to general inflationary impacts and labor market challenges overall, specific increases include pipeline integrity, reliability, line location, and engineering services costs ($12 million), increased cost of fuel (nearly $8 million, almost half of which is used in our operations), an increase in the reserve for customer accounts deemed uncollectible ($7.8 million), approximately $8 million in contractor/professional services in various areas of the business, higher legal and claim-related costs ($6 million), employee travel and training costs ($2.5 million), and higher labor-related costs ($2.6 million).
Depreciation and amortization expense increased $8.8 million, or 3%, between periods primarily due to a $531 million, or 6%, increase in average gas plant in service since the corresponding period in the prior year, offset by a reduction ($4 million) in amortization of regulatory account balances, as discussed in regard to Operating margin above. The increase in gas plant was attributable to pipeline capacity reinforcement work, franchise requirements, scheduled pipe replacement activities, and new infrastructure.
Other income increased $14 million between the twelve-month periods of 2023 and 2022. Interest income increased $18.7 million between periods related to carrying charges associated with regulatory account balances, notably deferred purchased gas cost balances, which have increased substantially since the comparable period in the the prior year. Non-service-related components of employee pension and other postretirement benefit costs decreased $15.1 million between periods. Offsetting these impacts was a $5.1 million decline in COLI results between periods, a $9 million reserve for a software project deemed non-recoverable from utility operations, and a $3 million market adjustment on other property in 2022.
Net interest deductions increased $26 million between periods primarily due to $600 million of Senior Notes issued in March 2022, $300 million of Senior Notes issued in December 2022, and, to a lesser extent, $300 million of Senior Notes issued in March 2023. Other impacts include increased interest associated with a higher amount of short-term debt and higher rates on variable-rate debt overall, including under Southwest’s credit facility.
32


Income tax expense increased $3.7 million between the twelve-month periods ended March 31, 2023 and 2022, primarily due to amortization of excess accumulated deferred income taxes (“EADIT”) ($5.3 million), changes in Arizona and California state apportionment percentages of $3.2 million, and return to provision differences of $5.1 million. Income tax expense in both periods reflects that COLI results are recognized without tax consequences.

Utility infrastructure services revenues increased $129.4 million in the first quarter of 2023 when compared to the prior-year quarter, driven primarily by a $51.7 million increase in electric infrastructure revenues and a $43.3 million increase in offshore wind revenue, which is reflected as a component of other revenues (refer to Note 3 – Revenue in this Quarterly Report on Form 10-Q). Offshore wind revenue stems from three multi-year contracts whereby Riggs Distler 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 growth from both new and existing customers as well as revenues of $30.6 million from emergency restoration services following tornado and other storm damage to customers’ above-ground utility infrastructure in and around the Gulf Coast and eastern regions of the U.S., compared to $14.1 million in storm restoration work in the prior-year quarter. 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 also included increased gas infrastructure services revenues of $36.7 million primarily resulting from $29.7 million of revenue related to a new bid contract that commenced during the first quarter of 2023, as well as favorable weather in several operating locations, which allowed projects in those areas to be completed during an otherwise seasonally slow period.
Utility infrastructure services expenses increased $100.4 million in the first quarter of 2023 when compared to the prior year quarter, driven primarily by a higher volume of work. Subcontractor costs increased during the first quarter of 2023 compared to the prior-year quarter primarily due to increased work under offshore wind projects. Despite continued inflationary pressures, operating margin in the first quarter of 2023 improved due to changes in the mix of work and increased operating efficiencies related to emergency restoration services, as well as favorable weather conditions in other locations. Also included in total Utility infrastructure services expenses were general and administrative costs, which decreased approximately $0.1 million between quarters due to the full integration of Riggs Distler as well as the impact of cost saving measures implemented in 2022. Gains on sale of equipment in the first quarter of 2023 and 2022 (reflected as an offset to Utility infrastructure services expenses) were approximately $661,000 and $413,000, respectively.
The increase in net interest deductions of $11.2 million was primarily due to higher interest rates on outstanding variable-rate borrowings.
Income tax benefit decreased $5 million between quarters, primarily due to a reduction in pre-tax loss in 2023 and changes in state apportionment rates.

Utility infrastructure services revenues increased $571.2 million in the current twelve-month period compared to the corresponding period of 2022, including a $408.4 million increase at Riggs Distler (acquired in August 2021), of which $132.9 million related to offshore wind projects that are reflected as a component of other revenues. Revenues from electric infrastructure services overall increased $216.6 million in the current twelve-month period when compared to the prior year, with $125.6 million attributable to Riggs Distler. Included in the incremental electric infrastructure revenues during the twelve-month period of 2023 was $86.1 million from emergency restoration services following storm damage to customers’ above-ground utility infrastructure in and around the Gulf Coast and eastern regions of the U.S. and Canada, as compared to $70.5 million in similar services during the twelve-month period in 2022. The remaining increase in revenue was attributable to continued growth with existing gas infrastructure customers under master service and bid agreements.
Utility infrastructure services expenses increased $506.7 million between periods. The overall increase included $373.7 million from Riggs Distler, and incremental costs related to the generally higher volume of work. Changes in the mix of work caused by customers’ supply chain challenges, as well as inflation, led to higher input costs including fuel and subcontractor expenses, as well as increased project-related travel and equipment rental costs incurred to fulfill electric infrastructure services. A loss of $7.5 million was incurred on a gas infrastructure bid project during the current twelve-month period due to higher costs than anticipated and scheduling delays. General and administrative costs, included in total Utility infrastructure services expenses, decreased approximately $3.4 million between comparative periods attributable to $13.9 million of professional fees incurred during the twelve-month period of 2022 in connection with the Riggs Distler acquisition that did not recur in 2023, offset by $6.1 million of strategic review and severance costs incurred in the current twelve-month period. Other administrative costs increased due to the growth in the business, including incremental costs incurred by Riggs Distler. Gains on sale of equipment (reflected as an offset to Utility infrastructure services expenses) were approximately $6.6 million and $5.8 million for the twelve-month periods of 2023 and 2022, respectively.
Depreciation and amortization expense increased $25.1 million between the current and prior-year twelve-month periods, of which $23.3 million relates to Riggs Distler.
Net interest deductions increased $42.1 million between periods due to incremental outstanding borrowings under Centuri’s $1.545 billion amended and restated secured revolving credit and term loan facility which funded the 2021 acquisition of Riggs Distler, in addition to higher interest rates on outstanding variable-rate borrowings.

Operating results for the pipeline and storage segment for the first quarter of 2023 reflect activity from January 1, 2023 through February 13, 2023 (the last full day of ownership by the Company). Operating results included rate-regulated transmission and subscription storage revenues of $34 million and $62 million during the three months ended March 31, 2023 and 2022, respectively. Operating expenses include $2.6 million during the current quarter related to integration/stand-up costs leading up to the sale date. Depreciation and amortization was not recorded in 2023 as MountainWest was classified as held for sale during the holding period. Income tax expense includes the impact of book versus tax basis differences related to the sale completed in 2023. A discussion of the twelve months ended March 31, 2023 to the comparable prior-year period is omitted as the Company owned MountainWest for only three months of the twelve-month period ended March 31, 2022. For further impacts from the sale on MountainWest to Southwest Gas Holdings, Inc. in the post-closing period, refer to Note 7 – Segment Information.
Rates and Regulatory Proceedings
Southwest is subject to the regulation of the Arizona Corporation Commission (“ACC”), the Public Utilities Commission of Nevada (the “PUCN”), the California Public Utilities Commission (the “CPUC”), and the Federal Energy Regulatory Commission (the “FERC”).
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 and reliable service 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. Southwest filed a general rate case application in December 2021, primarily to reflect in rates the substantial capital investments that were made since the end of the test year in an earlier case, including investments in a customer information system implemented in May 2021. At a hearing held in September 2022, Southwest, the 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 an acquisition premium related to the
35


recent Graham County acquisition as well as 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. Among the uncontested issues identified prior to the hearing were the continuation of the Delivery Charge Adjustment (“DCA”), Southwest’s full revenue decoupling mechanism, the continuation of the existing rate design (with the exception of an updated year-round Low Income Ratepayer Assistance program), and Southwest’s alternate property tax expense calculation, reflecting actual incurred property tax expense in 2021, instead of a pro-forma adjustment reflecting forecasted property tax expense. Approximately $12 million in costs related to the Liquefied Natural Gas facility deferred in an authorized regulatory asset will be amortized over four years. The ACC’s final order authorized a $54.3 million increase, with new rates effective February 1, 2023.
Delivery Charge Adjustment. The DCA is filed each April, which along with other reporting requirements, contemplates a rate to recover/return the over- or under-collected margin tracker (decoupling mechanism) balance. An April 2022 request proposed a rate to return $10.5 million, the over-collected balance existing at the end of the first quarter 2022, which became effective July 1, 2022. A filing was made prior to the end of April 2023 to request a rate to address the over-collected balance of $53.5 million as of March 31, 2023.
Tax Reform. 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 that which resulted from 2017 U.S. federal tax reform) compared to the amount authorized in the most recently concluded rate case. Following inaugural surcredit rate establishment under the TEAM mechanism, in December 2022, Southwest filed its most recent TEAM rate application, proposing to update the TEAM surcredit to refund $6.5 million of estimated net EADIT savings, which was approved by the ACC and will be effective May 1, 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. The 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 will increase the COYL recovery rate. The new rate is anticipated to become effective June 1, 2023.
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 2020 general rate case decision, 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 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 retained their existing rates while Southwest’s most recent rate case was processed; the customers moved to Southwest’s rates effective March 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 requests an expansion of the current gas cost balancing account (“GCBA”) adjustment to clear the then existing $351 million balance over one year, which would result in an increase of the current GCBA adjustment rate of $0.10 per therm to more than $0.50 per therm until the balance drops below $10 million, at which time the GCBA adjustment rate would be set to $0.00 per therm. The GCBA is in addition to ongoing deferred energy rates updated monthly. Expedited treatment was requested with a proposed June 1, 2023 implementation.
California Jurisdiction
Attrition Filing. Following the 2021 implementation of rates approved as part of the general rate case, and the continuing annual Post Test Year (“PTY”) attrition increases of 2.75% indicated above, the first such increase following the rate case effective date began in January 2022, with the most recent annual attrition increase effective January 1, 2023. The PTY increase associated with the North Lake Tahoe Lateral revenue requirement became effective February 1, 2023.

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 earlier 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 2023. This rate is expected to be updated at least annually.
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 offset their respective greenhouse gas (“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 a decision dismissing Southwest’s application without prejudice. Southwest anticipates filing a new application in 2023 addressing concerns raised by third parties as part of the earlier request, which included a request to demonstrate that purchased offsets would result in GHG emissions reductions.
Building Decarbonization. A CPUC decision was issued regarding the elimination of monetary allowances for gas line extensions, a 10-year refundable payment option, and the 50% discount payment option for both residential and non-residential customers of all California 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. A decision 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 imposes an annual disconnection cap and 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 with the first rates expected to be implemented January 1, 2024. The decision also authorized a memorandum account to track uncollected reconnection charges for possible future recovery in Southwest’s next general rate case.
Nevada Jurisdiction
Nevada General Rate Case. Southwest concluded its most recent Nevada general rate case in February 2022, 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 General Revenues Adjustment (“GRA”). 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 a COVID-19 moratorium on disconnections previously in place.
General Revenues Adjustment. As noted above, the continuation of the GRA was affirmed as part of Southwest’s most recent 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 2022 related to balances as of September 30, 2022. Given the magnitude of the outstanding balances, further discussion with the parties resulted in a settlement of the issues and utilizing a more current balance as of January 2023 to better align the rates implemented with the existing balance. Recovery rates and adjustments thereto as part of the ARA primarily impact cash flows but not net income overall.
