SOUTHWEST GAS HOLDINGS, INC.						Form 10-Q
SOUTHWEST GAS CORPORATION						March 31, 2024

Note 1 – Background, Organization, and Summary of Significant Accounting Policies

Nature of Operations. Southwest Gas Holdings, Inc. (together with its subsidiaries, the “Company”) is a holding company, owning all of the shares of common stock of Southwest Gas Corporation (“Southwest” or the “natural gas distribution” segment), and through the first quarter of 2024, all of the shares of common stock of Centuri Group, Inc. (“utility infrastructure services” segment), and until February 14, 2023, all of the shares of common stock of MountainWest Pipelines Holding Company (“MountainWest” or the “pipeline and storage” segment). References throughout this document in reference to “Centuri” relate to Centuri Group, Inc., for earlier periods or more recently, to Centuri Holdings, Inc.

In December 2022, the Company announced that its Board of Directors (the “Board”) unanimously determined to take strategic actions to simplify the Company’s portfolio of businesses. These actions included entering into a definitive agreement to sell 100% of MountainWest to Williams Partners Operating LLC (“Williams”) for $1.5 billion in total enterprise value, subject to certain adjustments (collectively, the “MountainWest sale”). The MountainWest sale closed on February 14, 2023.

As part of this simplification strategy, the Company previously communicated that it would pursue a separation of Centuri. In April 2024, the Company announced the completion of an initial public offering (“IPO”) of Centuri Holdings, Inc. common stock, with the issuance of 14,260,000 shares ($0.01 par value) at $21.00 per share, along with a private placement of 2,591,929 shares at the same public offering price with Icahn Partners LP and Icahn Partners Master Fund LP, investment entities associated with Carl C. Icahn. The Company owns approximately 81% of Centuri following these events. Through the first quarter of 2024 and leading up to the IPO, Centuri continued to be wholly owned by Southwest Gas Holdings, Inc. Centuri continues to be consolidated as part of these financial statements, and will continue to be consolidated until such time as the conditions for consolidation are no longer met. Centuri now makes separate filings with the Securities and Exchange Commission (the “SEC”) as a public company. The Company’s common stock continues to trade under the ticker symbol “SWX,” while Centuri’s common stock trades under the ticker symbol “CTRI.” As part of the IPO and related undertakings, and to ultimately facilitate a full separation of Centuri over periods ahead, multiple agreements were executed between the Company and Centuri, including a Separation Agreement, a Tax Matters Agreement, and a Registration Rights Agreement. Centuri’s new Board of Directors includes certain overlapping board members with the Company, including Andrew W. Evans, Anne L. Mariucci, and Karen S. Haller (the Company’s Chief Executive Officer). See also Note 8 - Dispositions.

Southwest is engaged in the business of purchasing, distributing, and transporting natural gas for customers in portions of Arizona, Nevada, and California. Public utility rates, practices, facilities, and service territories of Southwest are subject to regulatory oversight. The timing and amount of rate relief can materially impact results of operations. Natural gas purchases and the timing of related recoveries can materially impact liquidity, highlighted by the significant amount of cash existing as of the end of the first quarter of 2024, reflective of the collection of gas cost under purchased gas cost mechanisms as a component of customer bills. While mechanisms exist in all states in which Southwest operates, which effectively and primarily decouple authorized operating cost recovery and profitability from the volume of natural gas sold, thereby also incentivizing energy conservation, results for the natural gas distribution segment are higher during winter periods due to the seasonality incorporated in its regulatory rate structures.

Centuri is a strategic utility infrastructure services company dedicated to partnering with North America’s gas and electric providers to build and maintain the energy network that powers millions of homes across the United States (“U.S.”) and Canada. Centuri derives revenue primarily from installation, replacement, repair, and maintenance of energy networks. Centuri operates in the U.S., primarily as NPL, Neuco, Linetec, and Riggs Distler, and in Canada, primarily as NPL Canada. Utility infrastructure services activity is seasonal in many of Centuri’s operating areas. Peak periods are the summer and fall months in colder climate areas, such as the northeastern and midwestern U.S. and in Canada. In warmer climate areas, such as the southwestern and southeastern U.S., utility infrastructure services activity continues year round.

Basis of Presentation. The condensed consolidated financial statements of Southwest Gas Holdings, Inc. and subsidiaries and Southwest (with its subsidiaries) included herein have been prepared pursuant to the rules and regulations of the SEC. The year-end 2023 condensed balance sheet data was derived from audited financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. No substantive change has occurred with regard to the Company’s business segments on the whole during the recently completed quarter.

The preparation of the condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, as of the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. In the opinion of management, all adjustments, consisting of normal recurring items and estimates necessary for a fair statement of results for the interim periods, have been made.

SOUTHWEST GAS HOLDINGS, INC.						Form 10-Q
SOUTHWEST GAS CORPORATION						March 31, 2024

These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto of Southwest and the Company included in our 2023 Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

In the first quarter of 2023, management identified a misstatement related to its accounting for the cost of gas sold at Southwest, thereby determining that Net cost of gas sold was overstated in 2021 and 2022 by $2.3 million and $5.7 million, respectively. Southwest made an adjustment in the first quarter of 2023 to reduce Net cost of gas sold and to increase its asset balance for Deferred purchased gas cost by $8 million.

Also in the first quarter of 2023, the Company identified an approximately $21 million misstatement related to its initial estimation of the loss recorded upon reclassifying MountainWest as an asset held for sale during the year ended December 31, 2022. Consequently, the impairment loss for the year ended December 31, 2022 was understated by approximately $21 million, which was corrected in the first quarter of 2023.

The Company (and Southwest, with respect to Net cost of gas sold) assessed, both quantitatively and qualitatively, the impact of these items on previously issued financial statements, concluding they were not material to any earlier period or to the period of correction.

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


(Thousands of dollars)	March 31, 2024		December 31, 2023
Net cash surrender value of COLI policies	$	150,182	$	146,546
Other property	6,080		6,112

Non-regulated property, equipment, and intangibles	1,750,380		1,752,094
Non-regulated accumulated provision for depreciation and amortization	(691,872)		(675,632)
Other property and investments	38,091		37,220
Total Southwest Gas Holdings, Inc.	$	1,252,861	$	1,266,340

Held for sale. In the first quarter of 2023, the Company and Southwest concluded certain assets associated with their previous corporate headquarters met the criteria to be classified as held for sale. As a result, the Company and Southwest reclassified approximately $27 million from Other property and investments to Current assets held for sale on their respective Condensed Consolidated Balance Sheets in the first quarter of 2023. In 2023, the Company and Southwest recorded an estimated loss of $5.2 million on the assets based upon an updated fair value less costs to sell. The sale was completed in January 2024.

Cash and Cash Equivalents. Cash and cash equivalents of the Company include $407.4 million and $48.9 million of money market fund investments at March 31, 2024 and December 31, 2023, respectively. Of these amounts, $407.2 million and $38.6 million at March 31, 2024 and December 31, 2023, respectively, were held by Southwest. Refer to discussion above regarding recent collections under Southwest’s purchased gas adjustment mechanisms.

Noncash investing activities include capital expenditures that were not yet paid, thereby remaining in accounts payable, amounts related to which declined by approximately $20.8 million and $9.6 million during the three months ended March 31, 2024, for the Company and Southwest, respectively; and declined approximately $37.3 million and $34.2 million during the three months ended March 31, 2023, for the Company and Southwest, respectively.

The Company and Southwest expanded their presentation in the first quarter 2024 to show the Change in short-term portion of credit facility and Repayment of short-term debt as separate line items within their Condensed Consolidated Statements of Cash Flows. The comparable prior-year period has been updated to reflect this change.

Prepaid and other current assets. Prepaid and other current assets for the Company and Southwest include, among other things, materials and operating supplies of $80.9 million at March 31, 2024 and $83.4 million at December 31, 2023 (carried at weighted average cost).

Goodwill. Goodwill is assessed as of October 1 each year for impairment, or more frequently, if circumstances indicate an impairment to the carrying value of goodwill may have occurred. The Company’s reporting units for goodwill are its operating segments, which are also its reportable segments. Since December 31, 2023, management qualitatively assessed whether events during the first three months of 2024 indicated it was more likely than not that the fair value of our reporting units was less than their carrying value, which if the case, could be an indication of a goodwill impairment. Through management’s assessments, no impairment was deemed to have occurred in the continuing segments of the Company. Goodwill in the Natural Gas

Other Income (Deductions). The following table provides the composition of significant items included in Other income (deductions) in Southwest’s and the Company’s Condensed Consolidated Statements of Income:


	Three Months Ended March 31,
(Thousands of dollars)	2024		2023
Southwest Gas Corporation:
Change in COLI policies	$	3,600	$	2,400
Interest income	9,776		12,471
Equity AFUDC	1,839		—
Other components of net periodic benefit cost	4,131		4,959

Miscellaneous income and (expense)	43		(5)
Corporate and administrative	(11)		270
Southwest Gas Holdings, Inc. - total other income (deductions)	$	18,121	$	18,460

Interest income primarily relates to Southwest’s regulatory asset balances, including its deferred purchased gas cost mechanisms, the combined balance of which ranged from $970 million as of March 31, 2023 to $199 million as of March 31, 2024. Refer also to Note 2 – Components of Net Periodic Benefit Cost.

Redeemable Noncontrolling Interests. In connection with the acquisition of Linetec in November 2018, the previous owner initially retained a 20% equity interest in that entity, with redemption being subject to certain rights based on the passage of time or upon the occurrence of certain triggering events. Effective in 2022, the Company, through Centuri, had the right, but not the obligation, to purchase at fair value (subject to a floor) a portion of the interest held by the previous owner, and in incremental amounts each year thereafter. In March 2022, the parties agreed to a partial redemption, reducing the noncontrolling interest to 15%, and in March 2023, agreed to a partial 5% redemption (of the 15% then remaining). Then again in April 2023, Centuri paid $39.9 million to the previous owner, thereby reducing the balance continuing to be redeemable at that time to 10% under the terms of the original agreement. In March 2024, the parties entered into an agreement to redeem the remaining 10% equity interest for $92 million, which resulted in Centuri owning all of the equity interest in Linetec as of March 31, 2024. The Company paid the $92 million in April, in accordance with the agreement. The impact of this transaction has been excluded from the Company’s Condensed Consolidated Statement of Cash Flows for the first quarter of 2024 due to its noncash nature during the period.

Separately, certain members of Riggs Distler management have a 1.41% interest in Drum, which is redeemable, subject to certain rights based on the passage of time or upon the occurrence of certain triggering events. A portion of the redeemable noncontrolling interest was funded through promissory notes made to noncontrolling interest holders bearing interest at the prime rate plus 2%.


			15


SOUTHWEST GAS HOLDINGS, INC.						Form 10-Q
SOUTHWEST GAS CORPORATION						March 31, 2024

During the first quarter of 2024, Centuri forgave all outstanding promissory notes and unpaid interest owed from the Riggs Distler noncontrolling interest holders and in exchange obtained 0.47% portion of the equity interest in Drum that had been funded through these notes. This comprises most of the change noted below as redemption of Drum interests during the quarter. Additionally, during the first quarter of 2024, Centuri reached an agreement to purchase 0.13% of the noncontrolling interest in Drum for $0.8 million, the majority which was accrued in March 2024 and ultimately paid in April 2024. The impact of the accrued amount has been excluded from the Company’s Condensed Consolidated Statement of Cash Flows for the first quarter of 2024 due to the noncash nature in advance of the April 2024 payment. The remaining noncontrolling interest in Drum outstanding as of March 31, 2024 was 0.81%, with Centuri owning over 99% of Drum following these events.

Significant changes in the value of the redeemable noncontrolling interests, above a floor determined at the establishment date, are recognized as they occur, and the carrying value is adjusted as necessary at each reporting date. The fair value is estimated using a market approach that utilizes certain financial metrics from guideline public companies of similar industry and operating characteristics. Valuation adjustments also impact retained earnings, as reflected in the Company’s Condensed Consolidated Statement of Equity, but do not impact net income. The following depicts changes to the balances of the redeemable noncontrolling interests:


(Thousands of dollars):	Linetec		Drum		Total
Balance, December 31, 2023	$	91,978	$	12,689	$	104,667
Net income (loss ) attributable to redeemable noncontrolling interests	(193)		18		(175)
Redemption value adjustments	194		—		194
Redemption of equity interest from noncontrolling party	(91,979)		(5,046)		(97,025)
Balance, March 31, 2024	$	—	$	7,661	$	7,661

Earnings Per Share. Basic earnings per share (“EPS”) in each period of this report were calculated by dividing net income attributable to Southwest Gas Holdings, Inc. by the weighted-average number of shares during those periods. Diluted EPS includes additional weighted-average common stock equivalents (performance shares and restricted stock units). Unless otherwise noted, the term “Earnings Per Share” refers to Basic EPS. A reconciliation of the denominator used in Basic and Diluted EPS calculations is shown in the following table:


	Three Months Ended March 31,
(In thousands)	2024	2023
Weighted average basic shares	71,728	68,265
Effect of dilutive securities:
Restricted stock units (1)	154	154
Weighted average diluted shares	71,882	68,419

(1) The number of securities included 136,000 and 132,000 performance shares during the three months ended March 31, 2024 and March 31, 2023, the total of which was derived by assuming that target performance will be achieved during the relevant performance period.

Income Taxes. The Company’s effective tax rate was 16.3% for the three months ended March 31, 2024, compared to 37.6% for the corresponding period in 2023. The effective rate decrease was primarily due to the MountainWest sale in 2023, which also included the impact of book versus tax basis differences related to the transaction (See Note 8 - Dispositions).

Southwest’s effective tax rate was 18.2% for the three months ended March 31, 2024, compared to 18.3% for the corresponding period in 2023. These amounts varied from the statutory rate primarily as the result of the amortization of excess deferred income taxes.

In April 2023, the Internal Revenue Service issued Revenue Procedure 2023-15, which provides a safe harbor method of accounting that taxpayers may use to determine whether expenditures to repair, maintain, replace, or improve natural gas transmission and distribution property must be capitalized for tax purposes. The Company and Southwest are currently reviewing this revenue procedure to determine the potential impact on their financial position, results of operations, and cash flows.

Recent Accounting Standards Updates.

Recently issued accounting pronouncement that will be effective in 2024 and later periods:

In November 2023, the Financial Accounting Standards Board (the “FASB”) issued ASU 2023-07 “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” The update, among other amendments, requires disclosure of significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit or loss, as well as an amount and description of the composition of other segment items to reconcile to segment profit or loss, and also requires the title and position of the entity’s CODM to be disclosed. The update additionally extends certain annual disclosures to interim periods. The provisions of the update are effective for fiscal years beginning after December 15, 2023 and interim periods within the fiscal years beginning after December 15, 2024. Early adoption is permitted. Management is evaluating the impacts this update might have on the Company’s and Southwest’s disclosures.

Recently issued accounting pronouncement that will be effective after 2024:

In December 2023, the FASB issued ASU 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The update, among other amendments, provides for enhanced income tax information primarily through changes in the rate reconciliation and income taxes paid. The update is effective for annual periods beginning after December 15, 2024; early adoption is permitted. Management is evaluating the impacts this update might have on the Company’s and Southwest’s disclosures.

Note 2 – Components of Net Periodic Benefit Cost

Southwest has a noncontributory qualified retirement plan with defined benefits covering substantially all employees (those hired before 2022) and a separate unfunded supplemental retirement plan (“SERP”), which is limited to officers hired before 2022. Southwest also provides limited postretirement benefits other than pensions (“PBOP”) to its qualified retirees for health care, dental, and life insurance.

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

Note 3 – Revenue

The following information about the Company’s revenues is presented by segment. Southwest encompasses the natural gas distribution segment and Centuri encompasses the utility infrastructure services segment.

Natural Gas Distribution Segment:

Southwest’s operating revenues included on the Condensed Consolidated Statements of Income of both the Company and Southwest include revenue from contracts with customers, which is shown below, disaggregated by customer type, in addition to other categories of revenue:


	Three Months Ended March 31,
(Thousands of dollars)	2024		2023

Total Regulated operations revenues	$	1,052,933	$	914,879

(1) Amounts include late fees and other miscellaneous revenues, and may also include the impact of certain regulatory mechanisms.

Utility Infrastructure Services Segment:

During the fourth quarter of 2023, Utility infrastructure services segment management, in connection with Centuri’s planned separation, changed its service type revenue classification to align with changes in its organizational structure, and as a result, prior year “other” revenue has been recast into gas infrastructure services or electric power infrastructure services to reflect these changes, with no impact to revenue overall. The following tables display Centuri’s revenue, reflected as Utility infrastructure services revenues on the Condensed Consolidated Statements of Income of the Company, representing revenue from contracts with customers disaggregated by service and contract types:


	Three Months Ended March 31,
(Thousands of dollars)	2024		2023*
Service Types:
Gas infrastructure services	$	261,226	$	298,640

The following table provides information about contracts receivable and revenue earned on contracts in progress in excess of billings (contract assets), both of which are included within Accounts receivable, net of allowances, as well as amounts billed in excess of revenue earned on contracts (contract liabilities) at Centuri, which are included in Other current liabilities as of March 31, 2024 and December 31, 2023 on the Company’s Condensed Consolidated Balance Sheets:


(Thousands of dollars)	March 31, 2024		December 31, 2023
Contracts receivable, net	$	287,815	$	347,454
Revenue earned on contracts in progress in excess of billings	257,830		269,808
Amounts billed in excess of revenue earned on contracts	13,648		43,694

Revenue earned on contracts in progress in excess of billings (contract assets) that are not expected to be recognized within a year from the financial statement date are not included in the table above, and were $16.5 million as of March 31, 2024, and $0.2 million as of December 31, 2023. These non-current balances were included in Deferred charges and other assets on the Company’s Condensed Consolidated Balance Sheets.

These contract assets primarily relate to Centuri’s rights to consideration for work completed, but not billed and/or approved for billing at the reporting date, and are transferred to contracts receivable when the rights become unconditional. The amounts billed in excess of revenue earned primarily relate to the advance consideration received from customers for which work has not yet been completed. The decrease in the contract liability balance from December 31, 2023 to March 31, 2024 of $30 million was due to revenue recognized during the period, net of new payments received in advance of work performed.

For contracts that have an original duration of one year or less, Centuri uses the practical expedient applicable to such contracts and does not consider/compute an interest component based on the time value of money. Furthermore, because of the short duration of these contracts, Centuri has not disclosed the transaction price for the remaining performance obligations as of the end of each reporting period or when the Company expects to recognize the revenue.

As of March 31, 2024, Centuri had 53 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, 2024 was $277 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.

Utility infrastructure services contracts receivable consists of the following:


(Thousands of dollars)	March 31, 2024		December 31, 2023
Billed on completed contracts and contracts in progress	$	285,896	$	348,021
Other receivables	1,989		1,945

SOUTHWEST GAS HOLDINGS, INC.						Form 10-Q
SOUTHWEST GAS CORPORATION						March 31, 2024

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, 2024, 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, 2024, 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 and term loan facility are based on either a “base rate,” SOFR or the Canadian Dollar Offered Rate (“CDOR”), plus an applicable margin. The capacity of the line of credit portion of the facility is $400 million; related amounts borrowed and repaid are available to be re-borrowed. The term loan portion of the facility has a limit of $1.145 billion. The obligations under the credit agreement are secured by present and future ownership interests in substantially all direct and indirect subsidiaries of Centuri, substantially all of the tangible and intangible personal property of each borrower, certain of their direct and indirect subsidiaries, and all products, profits, and proceeds of the foregoing. Centuri’s assets securing the facility at March 31, 2024 totaled $2.4 billion. At March 31, 2024, $1.1 billion in borrowings were outstanding under Centuri’s combined secured revolving credit and term loan facility.

On March 22, 2024, Centuri amended the financial covenants of its revolving credit facility to increase the maximum total net leverage ratio for the fiscal quarter ending March 31, 2024 to a ratio of 5.75 to 1.00, for the fiscal quarter ending June 30, 2024 to a ratio of 6.00 to 1.00, and for the fiscal quarter ending September 30, 2024 to a ratio of 5.75 to 1.00. In addition, this amendment increased the adjusted maximum total net leverage ratio financial covenants, which are applicable in the event that a “Qualified IPO” (as defined in the amendment) is consummated, for each of the fiscal quarters ending March 31, 2024, June 30, 2024, and September 30, 2024. The terms of the Centuri credit facility otherwise remain unchanged. Following the IPO and private placement, Centuri used approximately $316 million of proceeds to pay down $156 million of debt under the existing line of credit and $160 million of debt under the term loan portion of the facility, with the remainder intended for general corporate purposes.

Short-Term Debt

Southwest Gas Holdings, Inc. has a $300 million credit facility that is scheduled to expire in December 2026 and is primarily used for short-term financing needs. Interest rates for the credit facility are calculated at either SOFR or the “alternate base rate,” plus in each case an applicable margin. There was $94 million outstanding under this credit facility as of March 31, 2024.

In April 2023, Southwest Gas Holdings, Inc. entered into a $550 million Term Loan Credit Agreement (the “Term Loan”) that matures in October 2024. Southwest Gas Holdings, Inc. utilized a majority of the proceeds to make an equity contribution to Southwest.

As indicated above, under Southwest’s $400 million credit facility, no short-term borrowings were outstanding at March 31, 2024.

Note 8 - Dispositions

Dispositions

In December 2022, the Company announced that the Board unanimously determined to take strategic actions to simplify the Company’s portfolio of businesses. These actions included entering into a definitive agreement to sell 100% of MountainWest in an all-cash transaction to Williams for $1.5 billion in total enterprise value, subject to certain adjustments. The MountainWest sale was completed in February 2023. Additionally, the Company determined it would pursue a separation of Centuri to form a new independent publicly traded utility infrastructure services company.

As discussed in Note 1 - Background, Organization, and Summary of Significant Accounting Policies, in April 2024, the Company and Centuri Holdings, Inc. announced the completion of an IPO of 12,400,000 shares of Centuri’s common stock at a


			25

price of $21.00 per share. Centuri granted the underwriters a 30-day option to purchase up to an additional 1,860,000 shares of its common stock, which was exercised. In addition, Centuri announced the concurrent private placement of an additional 2,591,929 shares at a price equal to the IPO price. Centuri’s common stock is listed on the New York Stock Exchange under the symbol “CTRI” and began trading on April 18, 2024. The net proceeds to Centuri from the IPO and the concurrent private placement, after deducting underwriting discounts and commissions of $18 million and estimated offering expenses, were approximately $329 million. Centuri used the proceeds to repay a portion (approximately $316 million) of outstanding indebtedness under its revolving credit and term loan facility, with the remainder for general corporate purposes.

After completion of the IPO, and above undertakings, the Company continues to own approximately 81.0% of all ownership interests in Centuri. The Company intends to further reduce its ownership in future periods through sales of its remaining Centuri shares into the market, a distribution of Centuri shares to Company stockholders, or an exchange of Centuri shares for Southwest Gas Holdings, Inc. shares, or a combination thereof. The Company entered into several agreements with Centuri Holdings, Inc. in connection with the IPO and the planned separation, providing a framework for the relationship between the Company and Centuri after the IPO.

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 through the first quarter of 2024 all of the shares of common stock of Centuri Group, Inc. (the “utility infrastructure services” segment). Southwest Gas Holdings, Inc. and its subsidiaries are collectively referred to as the “Company.” References to “Centuri” relate to Centuri Group, Inc., for earlier periods, or more recently, to Centuri Holdings, Inc,

In December 2022, the Company announced that its Board of Directors (the “Board”) unanimously determined to take strategic actions to simplify the Company’s portfolio of businesses. These actions included entering into a definitive agreement to sell 100% of MountainWest in an all-cash transaction that closed on February 14, 2023. Additionally, the Company determined it would pursue a separation of Centuri to form a new independent publicly traded utility infrastructure services company.

In April 2024, the Company and Centuri Holdings, Inc. announced the completion of an initial public offering (“IPO”) of Centuri’s common stock, with the issuance of 14,260,000 shares ($0.01 par value) at a price of $21.00 per share, along with a concurrent private placement of 2,591,929 shares, at a price equal to the IPO price, with Icahn Partners LP and Icahn Partners Master Fund LP, investment entities associated with Carl C. Icahn. The Company owns approximately 81% of Centuri following these events. Through the first quarter of 2024 and leading up to the IPO, Centuri continued to be a wholly owned subsidiary of Southwest Gas Holdings, Inc. The net proceeds to Centuri from the IPO and the concurrent private placement totaled approximately $329 million, including optional purchase of IPO shares from underwriters. The Company intends to further reduce its ownership interest in future periods through sales of its remaining Centuri shares into the market, a distribution of Centuri shares to Company stockholders, or an exchange of Centuri shares for Southwest Gas Holdings, Inc. shares, or a combination thereof.

Our business includes Southwest, which 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 also distributes and transports natural gas for customers in portions of California. Additionally, through its subsidiaries, Southwest operates two regulated interstate pipelines serving portions of Nevada and California. Southwest makes investments in infrastructure to support customer demand associated with population growth and economic development activity and the safe and reliable operation of its system through adherence to integrity management programs.

As of March 31, 2024, Southwest had 2,235,000 residential, commercial, industrial, and other natural gas customers, of which 1,197,000 customers were located in Arizona, 832,000 in Nevada, and 206,000 in California. Over the past twelve months, first-time meter sets were approximately 40,000, compared to 42,000 for the twelve months ended March 2023. Residential and small commercial customers represented over 99% of the total customer base. During the twelve months ended March 31, 2024, 54% of operating margin (Regulated operations revenues less the net cost of gas sold) was earned in Arizona, 33% in Nevada, and 13% in California. During this same period, Southwest earned 86% of its operating margin from residential and small commercial customers, 4% from other sales customers, and 10% 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 weather variability and conservation on operating margin, allowing Southwest to pursue energy efficiency initiatives. Nearly all of our


			27

customers, and resulting revenue and margin, are included as part of mechanisms that reduce the impact of weather and volume variability on our earnings.

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 a 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 87 primary locations across 45 states and provinces in the U.S. and Canada. 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. 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.

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.

This Management’s Discussion and Analysis (“MD&A”) of Financial Condition and Results of Operations should be read in conjunction with the unaudited condensed consolidated financial statements and notes thereto included in this Quarterly Report on Form 10-Q and the audited financial statements and notes thereto, as well as the MD&A included in the 2023 Annual Report to Stockholders, which is incorporated by reference into Southwest’s and the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, in addition to the Risk Factors included in these documents, and as updated from time to time.

Results from natural gas distribution operations improved $1.1 million between the first quarters of 2024 and 2023. The improvement was primarily due to an increase in Operating margin and decrease in Net interest deductions, offset by an increase in Depreciation and amortization.

Operating margin increased $9.2 million quarter over quarter. Approximately $5 million of incremental margin was attributable to customer growth, including 40,000 first-time meter sets during the last twelve months. Combined rate relief in Arizona and California added approximately $10 million of incremental margin. Increases in recoveries associated with regulatory programs of $6.5 million also contributed to the increase; an associated comparable increase is also reflected in amortization expense between periods (discussed below). Offsetting these increases was an $8 million out-of-period gas cost adjustment in the prior-year first quarter, and $4 million in higher 2024 gas cost used in operations that is offset in Operations and maintenance expense. The remaining variance primarily relates to changes in miscellaneous revenue and customers outside of the decoupling mechanism.

Operations and maintenance expense decreased $0.3 million (less than 1%) between quarters due to the change in the cost of fuel used in operations ($4 million discussed above), which was mostly offset by increases in employee-related labor and benefit costs. Cost containment of information technology-related outside services was mostly offset by increased costs for pipeline integrity management programs. Regulatory programs/mechanisms, however, such as those in place for incremental leak survey in Nevada and uncollectible residential customer account balances in California, as well as deployment of resources to capital projects, where applicable, reduce amounts that might otherwise be reflected in expense.

Depreciation and amortization expense increased $10.2 million, or 14%, between quarters, reflective of a $674 million, or 7%, increase in average gas plant in service since the corresponding first quarter of 2023; $6.5 million in higher amortization associated with recovery of regulatory program balances substantially contributed to the increase. The increase in plant was attributable to pipeline capacity reinforcement work, franchise requirements, scheduled pipe replacement activities, and new infrastructure.

Other income decreased $0.3 million. Interest income declined $2.7 million between quarters primarily reflecting a reduction to carrying charges associated with regulatory account balances, notably, deferred purchased gas cost balances, which decreased from $970 million as of March 31, 2023 to $199 million as of March 31, 2024. This decrease was offset by an $1.8 million increase in the equity portion of the allowance for funds used during construction and a $1.2 million increase in values underlying company-owned life insurance (“COLI”) policies between periods.


			30

Net interest deductions decreased $2.2 million in the first quarter of 2024, as compared to the prior-year quarter, primarily due to the payoff in April 2023 of a $450 million term loan, partially offset by the impacts of $300 million of Senior Notes issued in March 2023.

Utility infrastructure services revenues decreased $125.3 million, or 19%, in the first quarter of 2024 when compared to the prior-year quarter, driven primarily by decreased electric utility infrastructure services (“Electric”) revenues of $81.8 million, and decreased gas utility infrastructure services (“Gas”) revenues of $37.4 million. The decrease in Electric revenues was primarily due to a decrease in emergency restoration services of $21.4 million ($9.2 million in the first quarter of 2024 compared to $30.6 million in the first quarter of the previous year) due to less storm activity, a decrease in offshore wind revenues of $12.6 million due to timing of project completion, and a net reduction in volumes under existing master service agreements as a result of unfavorable weather and customer budget constraints. The decrease in Gas revenues was driven primarily by unfavorable weather, which drove a net reduction in volume under master services agreements with certain existing customers, as well as timing of completion of bid projects.

Utility infrastructure services expenses decreased $88 million, or 15%, in the first quarter of 2024 due primarily to a lower volume of infrastructure services provided. Subcontractor costs decreased during the first quarter of 2024 compared to the prior-year quarter primarily due to decreased work under offshore wind projects and change in the mix of work performed on offshore wind projects. Profit margins in the first quarter of 2024 decreased primarily due to inefficiencies caused by decreased volumes and unfavorable weather, changes in the mix of work, and a reduction in emergency restoration services which typically generate higher profit margins than core infrastructure services. Included in total Utility infrastructure services expenses were general and administrative costs, which increased approximately $5 million between quarters primarily due to $8.3 million in combined severance and strategic review costs in the first quarter of 2024 compared to just $0.2 million in similar costs in the first quarter of 2023. Gains on sale of equipment in the first quarter of 2024 and 2023 (reflected as an offset to Utility infrastructure services expenses) were approximately $0.9 million and $0.7 million, respectively.

Depreciation and amortization expense decreased $3.6 million between periods, primarily due certain tools/equipment within Electric operations becoming fully depreciated in 2023 and not requiring replacement based on project needs. Additionally, more efficient utilization of existing fixed assets in recent periods has slowed the growth of the depreciable asset base, highlighted by capital expenditures of $106.6 million in calendar year 2023 compared to $130.2 million in calendar year 2022.

The increase in net interest deductions of $1.7 million between quarters was primarily due to higher interest rates on outstanding variable-rate borrowings and higher borrowings on Centuri’s revolving line of credit in the first quarter of 2024 compared to the first quarter of the prior year.

Income tax benefit increased $8.4 million between quarters, primarily due to an increase in pre-tax loss in 2024.

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 two of Southwest’s subsidiaries are subject to regulation by the Federal Energy Regulatory Commission (the “FERC”).

Arizona Jurisdiction

Arizona General Rate Case. Southwest filed its 2024 Arizona rate case application in early February 2024, proposing an increase in revenue of approximately $126 million to reflect the continued significant capital investments in the state and to update rates to more closely align with Southwest’s current level of operations and maintenance expense. The request includes a return on common equity of 10.15% and a 0.81% fair value increment, relative to a 50% target equity ratio and a proposed twelve-month post-test year plant adjustment for otherwise non-revenue producing plant. In addition to proposing the continuation of full revenue decoupling under the Delivery Charge Adjustment (“DCA”) mechanism, Southwest proposed the establishment of the System Improvement Benefit (“SIB”) mechanism, a capital tracker designed to support required code and regulatory-related infrastructure replacements in the state of Arizona. Southwest also proposed to set the carrying cost for the interest component of the DCA and Gas Cost Balancing Account (“GCBA”) rate adjustment mechanisms to equal the Commission-authorized Weighted Average Cost of Capital, and to establish an Unrecovered Gas Cost Expense Provision (“UGCE”), which represents the gas cost-related portion of net write-offs of uncollectible customer accounts. The UGCE would allow Southwest to more timely recover commodity and related components of such accounts. Rates, following the conclusion of the rate case, are anticipated to become effective in the second quarter 2025. Southwest’s existing general rates became effective February 1, 2023 following conclusion of the previous general rate case.

Delivery Charge Adjustment. The DCA, or Arizona decoupling mechanism, as described above, includes a filing each April, which along with other reporting requirements, contemplates a rate to return/recover the over- or under-collected margin tracker (decoupling mechanism) balance. The existing rate to return the over-collected balance existing as of March 31, 2023 was approved and became effective August 1, 2023. The most recent filing was made in April 2024, requesting to update rates to address the $17.5 million over-collected balance existing as of March 31, 2024.

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 excess accumulated deferred income taxes (“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 the inaugural surcredit rate establishment under the TEAM mechanism in December 2022, Southwest has filed subsequent TEAM rate applications, including a recent filing, which proposes to update the TEAM surcredit to refund $5.03 million of estimated EADIT savings. The adjusted rate is anticipated to be implemented in the second quarter of 2024.

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 2024, Southwest requested approval to recover the outstanding revenue requirement of approximately $1.8 million associated with 2023 COYL investments. The existing rate, effective July 1, 2023, will remain in place until the new rate is approved.

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 requested an expansion of the current GCBA adjustment to clear the then existing $351 million balance. In July 2023, the ACC approved an increase to the GCBA rate (over a two-year period) effective August 1, 2023, to support the timely recovery of the approximately $358 million balance as of May 31, 2023. The increased GCBA rate will remain for up to two years or until the balance drops below $10 million, at which point the GCBA rate will be set to $0.00 per therm, where it will remain until the under- or over-collected balance exceeds $10 million. The ongoing deferred energy rates, separate from the GCBA rates, continue to be updated monthly.


			32

Nevada Jurisdiction

Nevada General Rate Case. Southwest filed its most recent general rate case in September 2023 based on the test year ended May 2023. The initial request was updated with a certification filing primarily for plant placed in service and incremental annual leak survey costs through November 2023. Those updates resulted in an updated overall request of $74 million, an increase over the initial request of $69.8 million. A stipulation was reached with Regulatory Operations Staff and the Bureau of Consumer Protection, settling certain issues and agreeing to a black box settlement with a statewide increase of $65.6 million, before any adjustments for the cost of capital. Following a hearing on cost of capital issues, the PUCN issued a decision approving an annual increase of revenues of $59 million, approving the proposed settlement, and authorizing a return on common equity of 9.5%, including the use of a hypothetical capital structure of 50% debt and 50% equity. Included in the settled items are a continuation of full revenue decoupling; authority to continue tracking incremental annual leak survey costs in a regulatory asset (discussed further below); and refreshed depreciation rates that are somewhat lower than proposed. New rates became effective in April 2024.

General Revenues Adjustment. The General Revenues Adjustment (“GRA”), or Nevada decoupling mechanism, was affirmed as part of Southwest’s most recently concluded general rate case and adjustments are included in the Annual Rate Adjustment (“ARA”) filings intended to update rates to recover/return amounts associated with various regulatory mechanisms, including the GRA. Southwest made its most recent ARA filing in November 2023 related to the approximate $8.7 million over-collected balance as of September 30, 2023. Recovery of rates and adjustments thereto as part of the ARA primarily impact cash flows, but not net income overall. Updated rates for the GRA and other regulatory mechanisms included in the ARA filing will become effective May 1, 2024, earlier than the typical July 1, 2024 effective date due to a commission-approved settlement.

Nevada Leak Survey. In 2019, the PUCN opened an Investigation and Rulemaking action to consider certain amendments to the Nevada Administrative Code requiring annual leak surveys of distribution pipelines transporting natural gas or liquid petroleum. The increased survey activity was to focus on business districts and to be conducted generally on an annual basis (not exceeding 15-month survey intervals). The proposed regulations were permanently adopted effective January 1, 2023. Regulatory asset treatment was approved for the purpose of tracking incremental costs associated with implementing the increased leak surveys. Continuation of the program, along with recovery of earlier incurred amounts over a two-year period, was approved in conjunction with Southwest’s recently completed general rate case.

California Jurisdiction

Attrition Filing. Following the 2021 implementation of rates approved as part of the most recent general rate case, the continuation of annual Post Test Year (“PTY”) margin attrition increases of 2.75% began in January 2022. The most recent annual margin attrition increase was also inclusive of adjustments related to the amortization of EADIT and the impact of the Automatic Trigger Mechanism (“ATM”) on authorized rate base. The ATM adjusts the rate of return up or down (in this case, up) as a result of changes in the average utility bond yield that exceed 100 basis points. The cumulative impact results in an annual increase of $6.9 million effective January 2024 for Southwest’s southern California, northern California, and South Lake Tahoe rate jurisdictions.

FERC Jurisdiction

General Rate Case. Great Basin Gas Transmission Company (“Great Basin”), a wholly owned subsidiary of Southwest, filed notice of a change in rates (pursuant to applicable regulations) on March 6, 2024, requesting that rates for natural gas service subject to the filing be made effective April 6, 2024. The FERC, however, suspended the case for a five-month period, which will allow rates to go into effect, subject to refund, September 6, 2024. The filing includes a request to continue a term-differentiated rate structure which was adopted as part of Great Basin’s last general rate case, an overall revenue increase of approximately $16 million, and a return on equity of 14.05% and 13.05% applicable to each category of shippers, as applicable, and a capital structure of 44% long-term debt and 56% common equity. A primary driver of the proposed increase is approximately $99 million of capital investments anticipated to be placed in service by the end of the August 31, 2024 test year. Motion rates, subject to refund, are anticipated to become effective in September 2024, subject to refund as indicated, with an initial decision during the second quarter of 2025.

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 March 31, 2024, under-collections in each of Southwest’s service territories resulted in an asset of $199 million on the Company’s and Southwest’s Condensed Consolidated Balance Sheets. The substantial reduction in balances receivable between periods in the table below reflects a combination of specific recovery rates in place to collect the build-up of earlier balances as a result of the cost paid for gas in those earlier periods, and recent conditions whereby base rates under the mechanisms have exceeded the cost of recent gas purchases with suppliers.

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).

The following table presents Southwest’s outstanding PGA balances receivable:


(Thousands of dollars)	March 31, 2024		December 31, 2023		March 31, 2023
Arizona	$	135,899	$	251,416	$	417,931
Northern Nevada	3,103		45,757		80,540
Southern Nevada	38,873		218,761		415,146
California	20,807		36,951		56,722
	$	198,682	$	552,885	$	970,339

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. In addition, certain national events, including several major storms in recent years affecting central portions of the U.S., have contributed to the periodic run-up in gas supply costs. This collective activity has necessitated the issuance of both debt and equity securities to supplement cash flows from operations. Southwest Gas Holdings, Inc. and Southwest’s capitalization strategy is to maintain an appropriate balance of equity and debt to preserve investment-grade credit ratings, which help minimize interest costs. Investment-grade credit ratings have been maintained by Southwest Gas Holdings, Inc. and Southwest.

Cash Flows

Southwest Gas Holdings, Inc.:

Operating Cash Flows. Cash flows provided by consolidated operating activities increased $729 million in the first three months of 2024 as compared to the same period of 2023. The increase was primarily driven by the change in purchased gas costs for Southwest, including amounts incurred and deferred, as well as impacts related to when amounts are incorporated in customer bills to recover or return deferred balances. As noted above, both the rates embedded in customer rates to support recovery of the previously elevated balance, and recent gas supply costs that have been lower than base tariff gas cost rates billed to customers have in combination substantially reduced the balances receivable under our PGA mechanisms. These conditions have provided a significant source of available funds in the current period. The improvement in cash flows also reflect the impacts of changes in other components of working capital overall, including the timing and amount of accounts payable and other current asset and liability balances.

Corporate and administrative expenses/outflows for Southwest Gas Holdings, Inc. in the three-month period ended March 31, 2024 mainly include interest paid on borrowings and costs associated with the Centuri separation.

Investing Cash Flows. Cash flows provided by consolidated investing activities decreased $1.04 billion in the first three months of 2024 as compared to the same period of 2023. The overall decrease was driven by $1.06 billion in proceeds received in connection with the MountainWest sale (net of cash sold) in 2023, partially offset by proceeds from the sale of other property.


			34

Financing Cash Flows. Cash flows from consolidated financing activities increased $723 million in the first three months of 2024 as compared to the same period of 2023. The overall increase was primarily due to 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 connection with the 2021 acquisition of MountainWest, with no comparable repayment in the current year. Offsetting the increase between periods were impacts also primarily occurring in 2023, including proceeds received from the issuance of common stock in underwritten public offerings in March 2023 and debt proceeds by Southwest from the 364-day $450 million term loan to address an escalation in gas purchases (entered into in January 2023 and repaid in full in April 2023). The first quarter of 2023 also included $300 million of Senior Notes issued by Southwest. Other financing cash flows include borrowings and repayments under the companies’ credit facilities, and an increase in dividends paid.

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.

Southwest Gas Corporation:

Operating Cash Flows. Cash flows provided by operating activities increased $806 million in the first three months of 2024 as compared to the same period of 2023. The improvement in operating cash flows was primarily attributable to deferred gas costs change (as discussed above), as well as to other working capital changes.

Investing Cash Flows. Cash used in investing activities decreased $28 million in the first three months of 2024 as compared to the same period of 2023. While outflows for capital expenditures were generally comparable between periods, the current period reflects offsetting inflows due to proceeds received from the sale of property, as well as reduced outflows related to activity associated with customer advances for construction. See also Natural Gas Distribution Segment Construction Expenditures, Debt Maturities, and Financing below.

Financing Cash Flows. Net cash from financing activities decreased $480 million in the first three months of 2024 as compared to the same period of 2023. The decline was primarily due to activity during the first quarter of 2023, including Southwest’s issuance of a $450 million term loan in January 2023 along with the issuance of $300 million notes in the same quarter, offset by a $225 million term loan repayment in that same quarter of the prior year. Dividends paid and borrowing and repayment activity under the credit facility comprise the remaining activity between periods. See Note 5 – Debt.

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

During the three-month period ended March 31, 2024, construction expenditures for the natural gas distribution segment were $191 million (not including amounts incurred for capital expenditures not yet paid). The majority of these expenditures, approximately 51%, were associated with the replacement of existing transmission and distribution pipeline facilities to fortify system integrity and reliability, as well as other general plant expenditures, with the remainder related to new construction. These expenditures, along with the timing of capital projects, resulted in an increase in the construction work in progress balance as of March 31, 2024.

Management estimates natural gas segment construction expenditures during the three-year period ending December 31, 2026 will be approximately $2.4 billion. Of this amount, approximately $830 million is expected to be incurred during calendar year 2024. 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, 2026, Southwest will be required to renew or otherwise address its credit facility. Southwest has $75 million of long-term debt maturing in 2026, but otherwise no maturities in either 2024 or 2025. Also during that same three-year period, cash flows from operating activities of Southwest are expected to provide approximately 78% of the funding for gas operations of Southwest and total construction expenditures and dividend requirements. Any additional cash requirements, including construction-related, and any paydown or refinancing of debt, are expected to be provided by existing credit facilities, parent equity contributions, and/or other external financing sources. The timing, types, and amounts of additional external financings will be dependent on a number of factors, including the cost of gas purchases, conditions in capital markets, timing and amount of rate relief, timing and amount of surcharge collections from, or amounts returned to, customers related to other regulatory mechanisms and programs, as well as growth levels in Southwest’s service areas and earnings. External financings may include the issuance of debt securities, bank and other short-term borrowings, and other forms of financing.


			35

Dividend Policy

Dividends are payable on the Company’s common stock at the discretion of the Board. In setting the dividend rate, the Board considers, among other factors, current and expected future earnings levels, our ongoing capital expenditure plans, expected external funding needs, our payout ratio, and our ability to maintain investment-grade credit ratings and liquidity. The Company has paid dividends on its common stock since 1956. In February 2024, the Board determined to maintain the quarterly dividend at $0.62 per share, effective with the June 2024 payment. Although no assurances can be provided on our future dividend payments, the Board currently intends to reevaluate the dividend upon the completion of the Centuri separation, and it is anticipated that we will pay a dividend at a level consistent with industry peers.

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 March 31, 2024, the combined balance in the PGA accounts totaled an under-collection of $199 million, and the substantial reduction in the PGA balance as of this date compared to balances existing in recently concluded comparable earlier periods is also highlighted by the substantial cash balance of more than $400 million existing as of March 31, 2024. See PGA Filings for more information.

Southwest Gas Holdings, Inc. has a credit facility with a borrowing capacity of $300 million that expires in December 2026. This facility is intended for short-term financing needs. At March 31, 2024, $94 million was outstanding under this facility.

Southwest has a credit facility with a borrowing capacity of $400 million, which expires in April 2025. Southwest designates $150 million of the facility for long-term borrowing needs and the remaining $250 million for working capital purposes. There was no activity on either the long-term or short-term portions of the facility during the three-month period ending March 31, 2024. At March 31, 2024, no borrowings were outstanding on either the long-term or short-term portions of the facility. The credit facility can be used as necessary to meet liquidity requirements, including temporarily financing under-collected PGA balances, or meeting the refund needs of over-collected balances. The credit facility has generally been adequate for Southwest’s working capital needs outside of funds raised through operations and other types of external financing. Any additional cash requirements would include the existing credit facility, equity contributions from the Company, and/or other external financing sources.

Southwest has a $50 million commercial paper program. Any issuance under the commercial paper program is supported by Southwest’s current revolving credit facility and, therefore, does not represent additional borrowing capacity. Any borrowing under the commercial paper program is designated as long-term debt. Interest rates for the commercial paper program are calculated at the current commercial paper rate during the borrowing term. At March 31, 2024, there were no borrowings outstanding under this program.

Centuri has a $1.545 billion secured revolving credit and term loan multi-currency facility. The capacity of the line of credit is $400 million with related amounts borrowed and repaid available to be re-borrowed; the term loan facility has a limit of $1.145 billion. The term loan facility expires on August 27, 2028 and the revolving credit facility expires on August 27, 2026. This multi-currency facility allows the borrower to request loan advances in either Canadian dollars or U.S. dollars. 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 assets securing the facility at March 31, 2024 totaled $2.4 billion. The maximum amount outstanding on the combined facility during the first three months of 2024 was $1.117 billion. As of March 31, 2024, $125 million was outstanding on the revolving credit facility, in addition to $1 billion that was outstanding on the term loan portion of the facility. Also at March 31, 2024, there was approximately $201 million, net of letters of credit, available for borrowing under the line of credit.


			36

As discussed earlier, in April 2024, the successful completion of an IPO of 14,260,000 shares of Centuri common stock was completed at a price of $21.00 per share, in addition to a concurrent private placement of 2,591,929 shares at a price equal to the IPO price. The collective net proceeds to Centuri approximated $329 million.

Following the IPO, the Company owns approximately 81% of the outstanding shares of Centuri common stock. The Company intends to further reduce its ownership in Centuri in future periods through sales of its remaining Centuri shares into the market, a distribution of Centuri shares to Company stockholders, or through an exchange of Centuri shares for Southwest Gas Holdings, Inc. shares, or a combination thereof.

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 March 31, 2024, 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 first quarter of 2024 that have materially affected, or are likely to materially affect the Company’s internal control over financial reporting.
