The following are subsidiaries of Centuri: NPL Construction Co. (“NPL”), NPL Canada Ltd. (“NPL Canada”), New England Utility Constructors, Inc. (“Neuco”), Linetec Services, LLC (“Linetec”), and Riggs Distler & Company, Inc. (“Riggs Distler”), Canyon Pipeline Construction, Inc. (“Canyon”), National Powerline LLC (“Powerline”) andW.S. Nicholls Construction Inc. (“WSN Construction”). This presentation includes “forward-looking statements” as defined by the Securities and Exchange Commission (“SEC”). We make these forward-looking statements in reliance on the safe harbor protections provided under the Private Securities Litigation Reform Act of 1995. All statements, other than statements of historical facts, included in this presentation that address activities, events or developments that we expect, believe or anticipate will or may occur in the future are forward-looking statements. These include, without limitation, our 2022 expectations for our utility infrastructure services and natural gas operations segments, estimated natural gas operations capital expenditures, projected rate baseat December 31, 2026, our 2022 financial guidance and expected value drivers, as well as statements regarding the integration of our acquisition of MountainWest, our decision to separate Centuri from Southwest Gas Holdings, the strategic benefits of separation, the stand alone value propositions, energy transition expectations, financing plans, and otherinvestment opportunities. Forward-looking statements are based on assumptions which we believe are reasonable, based on current expectations and projections about future events and industry conditions and trends affecting our business. However, whether actual results and developments will conform to our expectations and predictions are subject to a number of risks and uncertainties that, among other things, could cause actual results to differ materially from those contained in the forward-looking statements, including without limitation, those discussed under the heading “Risk Factors”, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,”and “Quantitative and Qualitative Disclosure about Market Risk” in the Company’s most recent Annual Report on Form10-K and in the Company’s and Southwest Gas Corporation’s current and periodic reports, including our Quarterly Reports on Form 10-Q, filed from time to time with the SEC, and other reports that we file with the SEC from time to time, and the following: The timing and amount of rate relief, changes in rate design, customer growth rates, the effects of regulation/deregulation, tax reform and related regulatory decisions, the impacts of construction activity at Centuri, whether we will separate Centuri within the anticipated timeframe and the impact to our results of operations and financial position from the separation, the potential for, and the impact of, a credit rating downgrade, the costs to integrate MountainWest, future earnings trends, inflation, sufficiency of labor markets and similar resources, seasonal patterns, the cost and management attention of ongoing litigation that the Company is currently engaged in, the costs and effect of stockholder activism, including the cost and effects of the pending tender offer and proxy contest brought by Carl Icahn and his affiliates, and the impacts of stock market volatility. In addition, the Company can provide no assurance that its discussions about future operating margin, operating income, COLI earnings, interest expense, and capital expenditures of the natural gas distribution segment will occur. Likewise, the Company can provide no assurance that discussions regarding utility infrastructure services segment revenues, EBITDA as a percentage of revenue, and interest expense will transpire, nor assurance regarding acquisitions or their impacts, including management’s plans or expectations related thereto, including with regard to Riggs Distler or MountainWest. New factors that could cause actual results to differ materially from those described in forward-looking statements emerge from time to time, and it is not possible for us to predict all such factors, or the extent to which any such factor or combination of factors may cause actual results to differ from those contained in any forward-looking statement. The statements in this presentation are made as of the date hereof, even if subsequently made available on our Web site or otherwise. We do not assume any obligation to update the forward-looking statements provided to reflect events that occur or circumstances that exist after the date on which they were made. 2021 Year End Earnings Presentation 2 March 2, 2022

Non-GAAP Measures Non-GAAP Measures. This presentation 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 per diluted share, (ii) adjusted consolidated net income, (iii) utility infrastructure services segment adjusted net income, and (iv) corporate and administrative adjusted 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 for the three months and year ended Dec ember 31, 2021 includes adjustments to add back expenses related to the MountainWest acquisition and expenses related to the ongoing proxy contest and related stockholder litigation. Management believes that it is appropriate to adjust for expenses related to the MountainWest acquisition because they are one-time expenses that will not recur in future periods. Management believes it is appropriate to adjust for expenses related to the proxy contest and related stockholder litigation because these matters are unique and outside of the ordinary course of business for the Company. In addition, utility infrastructure adjusted net income and adjusted consolidated net income include adjustments related to one-time expenses related to the Riggs Distler acquisition. Management also uses the non-GAAP measure of operating margin related to its natural gas distribution operations. The Company 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 the Company’s profitability. Therefore, management routinely uses operating margin, defined by management as gas operating 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. 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. 2021 Year End Earnings Presentation 4 March 2, 2022

Non-GAAP Measure (IN THOUSANDS) Non-GAAP Measure Operating Margin – 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 as operating 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. Operating margin is not, however, specifically defined in accounting principles generally accepted in the United States (“U.S. GAAP”) and is considered a non-GAAP measure. 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.

Non-GAAP Measure UTILITY INFRASTRUCTURE SERVICES (IN MILLIONS) Non-GAAP Measure EBITDA - The following table presents the non-GAAP financial measures of EBITDA and Adjusted EBITDA for the twelve-month periods ended December 31, 1996 - 2021, which, when used in connection with net income attributable to Centuri, is intended to provide useful information to investors and analysts as they evaluateCenturi’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 attributable to Centuri or other measures of performance that are derived in accordance with GAAP. Management believes that the exclusion of these 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 below, (i) the nonrecurring write-off of deferred financing fees relates toCenturi’s amended and restated credit facility, (ii) acquisition costs vary from period to period depending on the level ofCenturi’s acquisition activity, and (iii) 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.
