Previously Announced Plan to Separate Centuri Remains On Track

Initiated 2024 Utility Earnings and Capital Expenditures Guidance and 2024-2026 Utility Adjusted Net Income CAGR and Rate Base CAGR Guidance

LAS VEGAS, Feb. 28, 2024 /PRNewswire/ -- Southwest Gas Holdings, Inc. (NYSE: SWX) ("Southwest Gas" or "Company") today reported fourth quarter 2023 consolidated net income of $72.9 million, or $1.01 per diluted share, and adjusted consolidated net income of $81.2 million, or $1.13 per diluted share. For the full-year ended December 31, 2023, consolidated net income was $150.9 million, or $2.13 per diluted share, and adjusted consolidated net income was $238.4 million, or $3.36 per diluted share. These results compared to a consolidated net loss of $(280.6) million, or $(4.18) per diluted share, and adjusted consolidated earnings of $78.0 million, or $1.16 per diluted share for the fourth quarter of 2022, and a consolidated net loss of $(203.3) million, or $(3.10) per diluted share, and adjusted consolidated net income of $196.6 million, or $3.00 per diluted share, for the full year ended December 31, 2022.

"I am pleased with the progress our team made throughout the past year to implement our strategic priorities and advance our transformation into a pure-play natural gas leader," said Karen Haller, Chief Executive Officer at Southwest Gas Holdings. "Continued strong customer growth, successful execution of our regulatory strategy, returns associated with elevated regulatory account balances, and higher COLI, all combined to improve results at Southwest Gas Corporation in 2023. We saw a 220 basis point step-up in utility ROE from 2022 levels and our adjusted net income results were $24 million above the $225 million high end of our expected range. The planned completion of our Nevada general rate case this Spring and our recent general rate case filing in Arizona provide the opportunity to start recovering the significant investments we have made to serve our customers.

"Centuri Group, Inc. ("Centuri") saw strong adjusted EBITDA, a 24% increase over 2022. With the successful onboarding of Bill Fehrman as President and CEO, progress toward the previously announced plan to separate Centuri into an independent utility infrastructure services company remains on track as we seek to unlock value for Southwest Gas shareholders," Haller added.

Southwest / Natural Gas Distribution - Fourth Quarter 2023

The natural gas distribution segment recorded net income of $91.7 million and adjusted net income of $95.2 million in the fourth quarter of 2023, compared to net income of $67.1 million (with no adjustments reported) in the fourth quarter of 2022. This was driven primarily by increases in operating margin and higher other income, partially offset by higher depreciation and amortization expenses, higher interest expense, and higher operations and maintenance expense.

Key drivers of fourth quarter 2023 performance as compared to fourth quarter 2022 include:

• Increased operating margin by $26 million compared to fourth quarter 2022, including the impacts of ~$4 million related to customer growth and ~$14 million primarily related to new general rates in Arizona (effective February 2023) to recover costs and investments made on behalf of customers through August of 2022, and to a lesser extent, the California attrition increase; the remainder of margin improvement relates primarily to revenue associated with other regulatory mechanisms for which the effects are mitigated by a comparable increase in amortization expense between the periods;
• An $11 million increase in Operations and maintenance expense primarily related to professional services for the utility optimization opportunity identification, benchmarking, and assessment initiative ($5 million), labor and labor-related benefit costs ($4 million), and leak survey and line locating activities ($1 million);
• Depreciation and amortization increased $6 million due to a higher level of gas plant in service, as well as higher regulatory account amortization ($2.4 million);
• Other income increased $25 million, $9 million of which is related to a prior year reserve for a non-recoverable software project that did not recur, a $5 million decrease in the non-service-related components of employee pension and other postretirement benefit costs, a $5 million higher increase in interest income related to carrying charges associated with regulatory account balances, including the Purchased Gas Adjustment mechanisms, $2 million in the allowance for equity funds used during construction, and a $2 million increase in COLI results;
• Interest expense increased $7 million compared to the fourth quarter of 2022, due to the issuance of $300 million of Senior Notes in December 2022 and $300 million of Senior Notes issued in March 2023; and
• Adjustments to recorded fourth quarter 2023 earnings included ~$4 million of collective after-tax consulting fees related to the utility optimization initiative, while the recorded fourth quarter 2022 earnings did not include any such adjustments.

Southwest / Natural Gas Distribution - Full Year 2023

The natural gas distribution segment recorded net income of $242.2 million and adjusted net income of $248.6 million in 2023, compared to net income of $154.4 million (with no adjustments reported) in 2022. This increase was driven primarily by increases in operating margin, higher other income and higher COLI results, partially offset by higher depreciation and amortization expenses, operations and maintenance expense, and interest expense.

Key drivers of 2023 performance as compared to 2022 include:

• Increased operating margin by $107 million compared to 2022, including the impacts of ~$14 million related to customer growth and ~$56 million primarily related to new general rates in Arizona effective February 2023 to recover costs and investments incurred for customers through November 2023, including certain adjustments through November 2024, as well as benefits of rate relief in Nevada through the first quarter of 2023 and the annual California attrition increase; the remainder of margin improvement relates to $19 million of revenue associated with other regulatory mechanisms for which the effects are mitigated by a comparable increase in amortization expense between the periods; an $8 million out-of-period adjusting entry that was made in the first quarter of 2023, which reduced net cost of gas sold; and margin associated with customers outside the decoupling mechanisms;
• A $20 million, or 4%, increase in O&M primarily related to increases throughout the business, including in external and professional services ($10 million, the majority of which relates to utility optimization consulting fees), direct labor ($8 million), leak survey and line locating activities ($4 million), higher incentive compensation expense ($4 million) and costs for fuel used in operations ($3 million). These were partially offset by lower employee benefit costs between periods (approximately $5 million reflected in O&M expense), primarily due to the lower service-related component of postretirement benefit costs offset by increases in employee medical and other costs; and legal/claim-related costs ($7 million);
• Depreciation and amortization increased $32 million, or 12%, between years, including from a $583 million, or 6%, increase in average gas plant in service compared to 2022, and a $19 million increase in regulatory account amortization as discussed in 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 $78 million reflecting $35 million higher interest income, related to carrying charges associated with the elevated deferred purchased gas cost balance and interest on other regulatory account balances, with another nearly $2 million associated with the equity portion of the allowance for funds used during construction. Additionally, non-service-related components of employee pension and other postretirement benefit costs decreased $21 million between years, thereby positively impacting results between periods; and a non-recurring $9 million reserve for a software project deemed non-recoverable from utility operations that was recorded in the prior year. Southwest also recognized a $16 million increase in COLI results between years;
• Interest expense increased $34 million compared to 2022, primarily due to interest associated with $300 million of Senior Notes issued in December 2022, and $300 million of Senior Notes issued in March 2023, and in part to $600 million of Senior Notes issued in March 2022, as well as a $450 million term loan, entered into in January 2023 to support higher natural gas supply costs, which was repaid in April 2023. These increases were offset by the March 2023 repayment of the remaining $225 million balance associated with the March 2021 Term Loan. Other impacts include increased interest associated with a higher amount of short-term debt and higher rates on variable-debt overall; and
• Adjustments to full year 2023 recorded earnings included $6 million of collective after-tax consulting fees related to optimization opportunity identification, benchmarking, and assessment, while the recorded full year 2022 earnings did not include any such adjustments.

Southwest / Natural Gas Distribution Segment Guidance and Outlook:

The Company has initiated the following forward-looking guidance for Southwest:

• 2024 net income guidance of $228 - $238 million (assumes $3 - $5 million of COLI earnings);
• 2024 capital expenditures in support of customer growth, system improvements, and pipe replacement programs of approximately $830 million;
• 2024 - 2026 adjusted net income compound annual growth rate of 10.0% - 12.0%;
• 2024 - 2026 capital expenditures of approximately $2.4 billion; and
• 2024 - 2026 utility rate base compound annual growth rate of 6.5% - 7.5%.

Centuri / Utility Infrastructure Services - Fourth Quarter 2023

The utility infrastructure services segment had a net loss of $(5.3) million and adjusted net loss of $(4.1) million in the fourth quarter of 2023, compared to net income of $6.5 million and adjusted net income of $6.7 million in the fourth quarter of 2022. The fourth quarter of 2022 benefited from adjustments to revenue as a result of re-negotiations of pricing within master service agreements ("MSAs") and significant storm restoration services revenues that did not recur in the fourth quarter of 2023. Only $3 million, or 3%, of the $86 million storm restoration services occurred during the fourth quarter of 2023, whereas 48% of the full-year 2022 amount occurred during the fourth quarter of 2022. 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.

Key drivers of Centuri's fourth quarter 2023 performance as compared to fourth quarter 2022 include:

• $107 million, or 13.8%, decrease in revenues, including a $46 million decrease in electric infrastructure services revenue, which primarily consisted of a $30 million decrease in storm restoration services revenue during the fourth quarter of 2023 when compared to the fourth quarter 2022, as the company was engaged to respond to the effects of hurricane Ian in the Southeast U.S. during the fourth quarter of 2022. Similar levels of storm restoration services were not required in the fourth quarter of 2023. The remaining decrease in electric infrastructure services revenue, as well as a $58 million decrease in gas infrastructure services revenue was mostly due to a net reduction in volumes under certain existing customer agreements due to budgetary constraints that did not exist in the prior year as well as changes in mix of electric infrastructure services work;
• ~$9 million decrease across infrastructure customers related to the timing of revenue recorded in the fourth quarter of 2022 as a result of re-negotiations of pricing within MSAs that were completed during the fourth quarter of 2022. No such timing items resulting from MSA re-negotiations occurred during the fourth quarter of 2023; the remaining decrease in revenues was driven primarily by a net reduction in volume of work under certain MSAs with existing customers due to customer budgetary constraints that did not exist in the prior year's fourth quarter;
• $87 million, or 12.5%, decrease in utility infrastructure services expenses, primarily as a result of decreased costs to complete a lower volume of work;
• Interest expense increased $3 million compared to the fourth quarter of 2022, reflective of higher short-term interest rates; and
• Adjustments to recorded fourth quarter 2023 earnings included $1 million of collective after-tax strategic review and Centuri separation costs, while the recorded fourth quarter 2022 earnings included a negligible amount of such costs.

Centuri / Utility Infrastructure Services - Full Year 2023

The utility infrastructure services segment had net income of $19.7 million and adjusted net income of $22.2 million in 2023, compared to net income of $2.1 million and adjusted net income of $3.5 million in 2022. Revenues increased $138.9 million compared to 2022, and operating income improved by 80%, reflecting, in addition to an increased volume of work, the effects of Centuri's effort to renegotiate MSAs across its customer base to capture in revenues the impacts of cost inflation that had compressed margins in 2022. In addition, cost management efforts and a favorable change in the mix of work in 2023 improved margins when compared to 2022.

Key drivers of Centuri's 2023 performance as compared to 2022 include:

• $139 million, or 5%, increase in revenues, driven primarily by a $212 million increase in electric infrastructure services revenue, which included a $120 million increase in offshore wind revenue. Offshore wind revenue stems from several multi-year contracts whereby Centuri provides materials, subcontracts manufacturing, and self performs fabrication and assembly of secondary steel components onshore, with delivery at a port facility. Also, a $17 million increase of 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., particularly during the first half of 2023. 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 remaining increase in electric infrastructure services revenue was due to higher volumes under certain existing customer MSAs. Partially offsetting these increases was an $82 million decrease in gas infrastructure services revenue driven primarily by lower volume under MSAs with certain existing customers, mostly in Canada, partly offset by increased revenue from bid work with a U.S. customer. Other revenues increased $9 million, primarily due to completion of a large industrial bid project during the year;
• $88 million, or 3.5%, increase in infrastructure services expenses, primarily as a result of increased costs to complete a higher volume of work. Subcontractor costs increased during 2023 compared to the prior year primarily due to increased revenue related to offshore wind projects. Despite continued inflationary pressures, margin on work completed in 2023 improved from the prior year due to changes in the mix of work and lower fuel prices. Also included in total Utility infrastructure services expenses were general and administrative costs, which increased approximately $1.3 million between years due to continued growth in the business. Gains on sale of equipment (reflected as an offset to Utility infrastructure services expenses) were approximately $4.5 million and $6.4 million in 2023 and 2022, respectively;
• $55 million increase in adjusted EBITDA that was the combined result of the higher volume of work and the successful re-negotiation of pricing within MSAs near the end of 2022, cost management efforts, and a favorable change in the mix of work in 2023 improved margins when compared to 2022;
• Improved adjusted EBITDA margin of 9.7% in 2023 compared with an adjusted EBITDA margin of 8.3% in 2022, with the improvements related to items described above;
• Depreciation and amortization expense remained largely consistent as a percentage of revenue between years. Amortization of intangible assets decreased in 2023 compared to 2022 due to Riggs Distler's backlog intangible asset becoming fully amortized in 2022;
• Increased interest expense of $36 million, driven by higher comparative short-term interest rates; and
• Adjustments to recorded full year 2023 earnings included ~$3 million of collective after-tax strategic review costs, while the recorded full year 2022 earnings included ~$1 million of such costs.

MountainWest / Pipeline and Storage – Fourth Quarter and Full Year 2023

Operating results for the pipeline and storage segment for 2023 reflect activity from January 1, 2023, through February 13, 2023 (the last full day of ownership by the Company), including residual goodwill impairment recognized during 2023. Operating expenses include ~$3 million during the first 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.

Southwest Gas Holdings - Fourth Quarter and Full Year 2023 and 2022

• Corporate and administrative expenses for the fourth quarter and year ended 2023 include respective $11 million and $43 million in interest expense related to borrowings and $4 million and $11 million in Centuri separation costs, offset by certain tax benefits while corporate and administrative expenses for the fourth quarter and year ended 2022 include respective $20 million and $48 million in interest expense related to borrowings and $6 million and $38 million in proxy contest, shareholders litigation, strategic review & CEO separation costs; and
• Adjustments to recorded fourth quarter 2023 earnings included $8 million of collective after-tax consulting fees related to optimization opportunity identification, benchmarking, and assessment, as well as strategic review costs and Centuri separation costs, while adjustments to the recorded fourth quarter 2022 earnings included respective $359 million of collective after-tax proxy contest, stockholder litigation, settlement agreement, strategic review, and Centuri separation costs, as well as MountainWest goodwill impairment and integration costs. Adjustments to recorded full year 2023 earnings include $88 million of collective after-tax consulting fees related to optimization opportunity identification, benchmarking, and assessment, as well as strategic review costs and Centuri separation costs, and MountainWest goodwill impairment and integration costs, while adjustments to recorded full year 2022 earnings include $400 million of collective after-tax proxy contest, stockholder litigation, settlement agreement, strategic review and Centuri separation costs, and MountainWest goodwill impairment and integration costs.

Centuri Separation Update

Southwest Gas and its Board of Directors (the "Board") continue to make progress on their commitment to simplify the Company's portfolio of businesses. On September 22, 2023, Centuri Holdings confidentially submitted a draft registration statement on Form S-1 with the SEC. On December 4, 2023, the Board announced the Centuri Holdings IPO as the preferred path to advance the separation of Centuri as an independent utility infrastructure services company to maximize value for Southwest Gas stockholders.

In early January 2024, accomplished utility and energy executive Bill Fehrman officially joined Centuri as its President and Chief Executive Officer. Mr. Fehrman brings decades of utility experience, including having most recently served as President and Chief Executive Officer of Berkshire Hathaway Energy. With the addition of Mr. Fehrman, Southwest Gas reaffirms the previously communicated plan to advance the separation of Centuri as outlined in the December 4, 2023 press release.

Non-GAAP Measures. This earnings release contains financial measures that have not been calculated in accordance with accounting principles generally accepted in the U.S. ("GAAP"). These non-GAAP measures include (i) adjusted consolidated earnings (loss) per diluted share, (ii) adjusted consolidated net income, (iii) natural gas distribution segment adjusted net income (loss), (iv) pipeline and storage segment adjusted net income (loss), (v) utility infrastructure services segment adjusted net income (loss), and (vi) adjusted corporate and administrative net loss. Management uses these non-GAAP measures internally to evaluate performance and in making financial and operational decisions. Management believes that its presentation of these measures provides investors greater transparency with respect to its results of operations and that these measures are useful for a period-to-period comparison of results. Management also believes that providing these non-GAAP financial measures helps investors evaluate the Company's operating performance, profitability, and business trends in a way that is consistent with how management evaluates such performance. Adjusted consolidated net income (loss) for the twelve- months ended December 31, 2023 and 2022 includes adjustments to add back expenses related to the MountainWest acquisition and integration expenses, stockholder activism and litigation, proxy contest and settlement, consulting fees related to Utility optimization opportunity identification, benchmarking, and assessment, and the strategic review, along with losses on disposal groups held for sale, including goodwill impairment impacts and estimated selling costs, other costs associated with the sale, and costs incurred to facilitate the separation of Centuri. For the three-months ended December 31, 2023 and 2022, adjusted consolidated net income (loss) includes adjustments to add back expenses related to consulting fees related to Utility optimization opportunity identification, benchmarking, and assessment, and the strategic review and other costs incurred to facilitate the separation of Centuri. Management believes that it is appropriate to adjust for expenses related to the MountainWest acquisition and integration, for losses on held for sale businesses and for related costs, along with costs to facilitate a spin-off of Centuri, because they are expenses and charges that will not recur following these events. Management also believes it is appropriate to adjust for expenses related to stockholder activism, proxy contest settlement, and stockholder litigation, as well as the consulting fees related to Utility optimization and strategic review, because these matters are unique and outside of the ordinary course of business for the Company.

Management also uses the non-GAAP measure operating margin related to its natural gas distribution operations. Southwest recognizes operating revenues from the distribution and transportation of natural gas (and related services) to customers. Gas cost is a tracked cost, which is passed through to customers without markup under purchased gas adjustment ("PGA") mechanisms, impacting revenues and net cost of gas sold on a dollar-for-dollar basis, thereby having no impact on Southwest's profitability. Therefore, management routinely uses operating margin, defined by management as regulated operations revenues less the net cost of gas sold, in its analysis of Southwest's financial performance. Operating margin also forms a basis for Southwest's various regulatory decoupling mechanisms. Management believes supplying information regarding 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 Southwest Gas Holdings, Inc. Consolidated Earnings Digest included herein provides reconciliations for these non-GAAP measures.)

Management also uses the non-GAAP measure EBITDA and Adjusted EBITDA related to its utility infrastructure services operations. EBITDA and Adjusted EBITDA, when used in connection with net income attributable to utility infrastructure services, is intended to provide useful information to investors and analysts as they evaluate Centuri's performance. EBITDA is defined as earnings before interest, taxes, depreciation and amortization, and Adjusted EBITDA is defined as EBITDA adjusted for certain other items as described below. These measures should not be considered as an alternative to net income or other measures of performance that are derived in accordance with GAAP. Management believes that the exclusion of certain items from net income attributable to Centuri provides an effective evaluation of Centuri's operations period over period and identifies operating trends that might not be apparent when including the excluded items. As to certain of the items in the EBITDA and Adjusted EBITDA reconciliation table below, (i) non-recurring strategic review costs relate to a potential sale or spin-off of Centuri, and (ii) non-cash share-based compensation varies from period to period due to amounts granted in a given year. Because EBITDA and Adjusted EBITDA, as defined, exclude some, but not all, items that affect net income attributable to Centuri, such measures may not be comparable to similarly titled measures of other companies. The most comparable GAAP financial measure, net income attributable to Centuri, and information reconciling the GAAP and non-GAAP financial measures, are included in the utility infrastructure services EBITDA and Adjusted EBITDA reconciliation chart below.

We do not provide a reconciliation of forward-looking Non-GAAP Measures to the corresponding forward-looking GAAP measure due to our inability to project special charges and certain expenses.

Reconciliation of non-GAAP financial measure of Adjusted net income (loss) and Adjusted diluted earnings (loss) per share and their comparable GAAP measure of Net income (loss) and Diluted earnings (loss) per share is presented below. Note that the comparable GAAP measures related to net income (loss) are also included in Note 13 - Segment Information in the Company's December 31, 2023 Form 10-K.

Reconciliation of non-GAAP financial measures of EBITDA and Adjusted EBITDA and their comparable GAAP measures of Net income. Note that the comparable GAAP measures are also included in Note 13 - Segment Information in the Company's December 31, 2023 Form 10-K.
