  51. Committees of the Board

    Committees of the Board The standing committees of the Board are the Audit Committee, Compensation Committee, and Nominating and Corporate Governance Committee. In 2022, the Board formed a special committee, the Strategy Committee, which then became the Strategic Transactions Committee, to assist the Board in responding to the tender offer and proxy contest by Carl Icahn and in evaluating strategic alternatives for the Company and its subsidiaries. Pursuant to the Cooperation Agreement, for so long as the Icahn Group has the right to designate at least three members of the Board, three of such designees shall be included on the Strategic Transactions Committee. If the Icahn Group only has the right to designate two members of the Board, then both of such designees shall serve on the Strategic Transactions Committee. The Cooperation Agreement requires certain transactions to be approved by the Strategic Transactions Committee and sets forth certain deadlock procedures of the Strategic Transactions Committee applicable to certain decisions. Pursuant to the Cooperation Agreement, the Company also agreed to offer at least one of the Icahn Designees the opportunity to be a member of any currently existing or new committee of the Board, subject to certain limitations set forth in the Cooperation Agreement. The committees are composed solely of Independent Directors as outlined above. The table below shows the directors who served as members or chairs of each committee during 2024.

  55. Director Compensation Narrative

    Director Compensation Narrative In 2024, the Compensation Committee conducted a review of the types and amounts of director compensation. The independent compensation consultant engaged by the Compensation Committee conducted a benchmarking analysis of peer company director pay practices. Based on that analysis, the Compensation Committee decided to increase the annual retainer fees by $10,000, to increase the Nominating and Corporate Governance Committee Chair retainer fee by $5,000, and to increase the value of the annual equity grant to each director by $10,000 beginning on January 1, 2025. The Compensation Committee uses a retainer-based model for director cash compensation (without regular individual meeting fees) and determines the value of annual equity grants for directors based on a set dollar amount. Cash retainers are paid on a quarterly basis.

(2)Individual cash meeting fees of $1,200 are only payable when the number of meetings of the Strategic Transactions Committee exceeds 20 per calendar year. (3)Total Strategic Transactions Committee fees are capped at $90,000 per calendar year for the Chair and members. (4)At the February 2025 Board meeting, the Board determined that the fees for the chair and members of the Strategic Transactions Committee will no longer be paid after March 31, 2025. The annual cash retainer for non-employee directors was $95,000 for 2024 and is $105,000 for 2025, and the table above shows the additional cash retainers to be paid to committee chairs and members of the Strategic Transactions Committee in 2025. In 2024, the cash retainer paid to the Audit and Compensation Committee Chairs was $20,000 each, $15,000 to the Nominating and Corporate Governance Committee Chair, $54,000 to the Strategic Transactions Committee Chair, and $36,000 to each member of the Strategic Transactions Committee. Cash compensation received by the non-employee directors may be deferred until retirement or termination of their service as directors pursuant to the Directors Deferral Plan. Amounts deferred bear interest at 150% of the Moody’s Seasoned Corporate Bond Rate (“Bond Rate”). At retirement or termination, such deferrals will be paid out over 5, 10, 15 or 20 years, and will be credited during the applicable payment period with interest at 150% of the average of the Bond Rate on January 1 for the five years prior to retirement or termination. A fixed dollar value ($135,000 for 2024 and $145,000 for 2025) is granted annually in the form of equity compensation under the applicable equity incentive plan during each February Board meeting. The fixed dollar value is converted into awards representing a number of shares of Common Stock based on the closing share price for the last trading session of the most recently completed fiscal year. Under this program, in 2024, each member of the Board was granted the equivalent of 2,131 shares of Common Stock on February 22, 2024 under the Company’s 2017 Omnibus Incentive Plan and each member of the Board was granted the equivalent of 2,051 shares of Common Stock on February 20, 2025 under the Company’s 2024 Omnibus Incentive Plan.

  59. Director Compensation Narrative

    Non-employee director equity compensation vests immediately upon grant, and the directors are provided the option to defer receipt of equity compensation until they leave the Board. Deferred stock units are credited with notional dividends at the same time, in the same form, and in equivalent amounts as dividends that are payable from time to time on Common Stock. Such notional dividends are valued as of the date on which they are credited to the director and are reallocated into additional deferred stock units. When a director leaves the Board, any deferred stock units of such director will be converted into shares of Common Stock. Under the 2024 Omnibus Incentive Plan, as approved by the Company’s stockholders on May 2, 2024, the aggregate grant date fair value of equity that may be granted during any calendar year to any non-employee director, when combined with cash compensation paid by the Company to such director with respect to the same calendar year (whether or not such cash compensation is deferred) will not exceed $750,000 (or $1,000,000 in the calendar year in which the director commences service). Directors are entitled to participate in the same gift matching program that is available to all of our employees. Under this program, the Company matches contributions to qualified charitable organizations up to a maximum of $2,500 in any calendar year. Directors who are full-time employees of the Company or its subsidiaries receive no additional compensation for serving on the Board.

    (1)On February 22, 2024, each director serving at that time received a stock award of 2,131 shares which vested immediately, but receipt of the stock award may have been deferred by the director. The grant date fair value of the stock award for each director was $133,294. The Company does not issue option awards. (2)The stock awards are valued at the closing price of Common Stock on the date of grant. The grant date fair value of the stock award granted on February 22, 2024 was based on the closing price of Common Stock of $62.55 on February 22, 2024. The amounts were determined in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 718. The assumptions used to calculate these amounts are included in “Note 9 - Share-Based Compensation” included in the footnotes to the consolidated financial statements in our 2024 Annual Report on Form 10-K.

  68. CEO Realized Compensation

    CEO Realized Compensation In evaluating Ms. Haller’s compensation for 2024, particularly her stock-based and cash-based incentive compensation, we believe it is important to consider, in addition to the information presented in the Summary Compensation Table, the value of the shares of Common Stock and the cash payments actually received by Ms. Haller in 2024. The primary difference between the 2024 Realized Compensation Table below and the Summary Compensation Table is that the 2024 Realized Compensation Table shows the value of shares and amount of cash actually received by Ms. Haller in 2024, whereas the Summary Compensation Table shows the grant date fair value of stock-based awards granted in 2024 and the annual cash incentive relating to 2024, the latter of which was actually paid in 2025. With respect to stock awards, SEC rules require that the grant date fair value of all stock awards be reported in the Summary Compensation Table in the year in which they were awarded. As a result, a significant portion of the total compensation amounts for 2024 reported in the Summary Compensation Table is based on the estimated value of stock awards when they are granted, rather than the value of the shares actually delivered upon vesting of the awards. By contrast, the 2024 Realized Compensation Table below reflects the value of the shares of Common Stock actually issued to Ms. Haller in 2024 in connection with the vesting of awards granted in 2024 and in prior years. In addition, SEC rules require that non-equity incentive plan compensation be reported in the Summary Compensation Table in the year earned, regardless of when the amounts are actually paid. The 2024 Realized Compensation Table below includes the amount of the 2023 incentive cash award paid to Ms. Haller in 2024, whereas the Summary Compensation Table shows the 2024 annual incentive award that was paid in the first quarter of 2025. In 2024, after the Centuri IPO, Ms. Haller began service as the Chair of the Centuri Board of Directors. Like all Centuri directors, Ms. Haller received director fees and time-lapse Centuri RSUs that will be settled in shares of Centuri common stock upon vesting, and such compensation elements are included in the Summary Compensation Table. Because these Centuri-related compensation items are set and approved by the Centuri Board of Directors, with input from the Company’s Board, and relate to Ms. Haller’s service as a Centuri director, these Centuri compensation elements have been excluded from the Realized Compensation table below. This methodology ensures focus on compensation related solely to the Company. As shown in the table below, Ms. Haller’s total realized compensation from the Company calculated in this manner was $4,694,875 for fiscal 2024, which was $2,296,635 less than the 2024 total direct compensation reported in the Summary Compensation Table.

  70. Retirement Benefits

    Retirement Benefits Four retirement benefit plans are available to the NEOs. Two of the plans, the Retirement Plan for Employees of Southwest Gas (“Retirement Plan”) and the Employee Investment Plan (“EIP”), both tax-qualified plans, are available to all Southwest Gas employees. The Retirement Plan is no longer offered to employees who started with Southwest Gas after December 31, 2021. Two additional plans are offered to officers, the Supplemental Executive Retirement Plan (“SERP”) and the Executive Deferral Plan (“EDP”). The SERP is no longer offered to officers who started with Southwest Gas after December 31, 2021. These additional plans were established to attract and retain qualified executives and to address the dollar limitations imposed on the two tax-qualified plans. ▪Retirement Plan for Employees Hired on or Before December 31, 2021. Benefits under the Retirement Plan are based on (i) the executive’s years of service with the Company, up to a maximum of 30 years, and (ii) the average of the executive’s highest five consecutive years’ salaries, within the final 10 years of service, not to exceed an annual maximum compensation level ($345,000 in 2024) periodically established by the Internal Revenue Service. ▪SERP for Officers Hired on or Before December 31, 2021. The SERP is designed to supplement the benefits under the Retirement Plan to a level of 50 - 60% of salary. To qualify for benefits under the SERP, which is based on a 12-month average of the highest consecutive 36-months of salary, an executive is required to have reached (i) age 55, with 20 years of service with the Company, or (ii) age 65, with 10 years of service. ▪EIP. NEOs may participate in the EIP and defer salary up to the maximum annual dollar amount permitted for 401(k) plans under the Internal Revenue Code. Investments of these deferrals are controlled by the individual executives from a selection of investment options offered through the EIP. There are no employer matching contributions for executive deferrals into the EIP, except for Mr. Stefani. Because Mr. Stefani is not eligible to participate in the Retirement Plan or the SERP, he receives a non-elective employer contribution of 3% of his salary and employer matching contributions on the first 7% of his EIP contributions. ▪EDP. The EDP supplements the deferral opportunities by permitting executives to defer up to 100% of their annual salary and non-equity incentive compensation. As part of the EDP, the Company provides matching contributions up to 3.5% of annual salary, which vest immediately. Amounts deferred and Company matching contributions bear interest at 150% of the Moody’s Seasoned Corporate Bond Rate (“Bond Rate”). At retirement with five years of service with the Company, the NEOs will receive EDP balances paid out at the election of the participant over a period of 10, 15 or 20 years, and will be credited during the applicable payment period with interest at 150% of the average of the Bond Rate on each January 1st for the five years prior to the start of retirement.

  73. Summary Compensation Table (2024, 2023 and 2022)

    (1)Amounts shown in this column include any amounts deferred by the NEOs into 401(k) and nonqualified deferral plans. For Ms. Haller, the increase in her salary between 2022 and 2023 resulted from her promotion to President and Chief Executive Officer of the Company. (2)Amounts shown in this column represent the aggregate grant date fair value of awards of PSUs and time-lapse RSUs granted in 2022, 2023 and 2024. In each case, the amounts were determined in accordance with FASB ASC Topic 718 based on the Common Stock share price on the date of grant. The value ultimately realized by the NEO upon actual vesting of the awards may or may not be equal to this determined value. The assumptions used to calculate these amounts are included in “Note 9 - Share-Based Compensation” included in the footnotes to the consolidated financial statements in our 2024 Annual Report on Form 10-K. However, as required, the amounts shown in this column exclude the impact of estimated forfeitures. PSU values were calculated based on the probable outcome of the performance conditions as of the grant date, which was determined to equal the target level of performance, except for the special PSUs granted in 2024 to Ms. Haller and Mr. Stefani as described below. PSUs generally vest upon completion of a three-year performance period, with the amount that vests based on the achievement of certain company financial targets. The performance period for the special 2024 PSUs granted to Mr. Brown is two years, with 50% vesting on the first and second anniversaries of the grant date, subject to the Company CEO’s determination that Mr. Brown has met the performance conditions. For the 2022 PSUs, the amount that vests is also subject to modification based on relative total stockholder returns and the final number of PSUs earned can range from 0% to a maximum of 195% (assuming the highest level of performance) of the number of PSUs granted. For the 2023 and 2024 PSUs, the final number of PSUs earned can range from 0% to 200% (assuming the highest level of performance) of the number of PSUs granted. Upon settlement, shares of Common Stock are issued for each earned PSU. The value of PSUs granted in 2024 (without taking into account the special PSUs), assuming achievement of the

  75. Summary Compensation Table (2024, 2023 and 2022)

    highest level of performance for the three-year performance period ending December 31, 2026, and using the closing price of Common Stock as of the date of grant in accordance with FASB ASC Topic 718, would be as follows: for Ms. Haller, $4,751,666; for Mr. Stefani, $1,558,954; for Mr. Brown, $1,504,717; for Mr. Gabe, $431,264; and for Ms. Williams, $663,130. The value of the special PSUs granted in 2024 to Mr. Brown, assuming achievement of the highest level of performance, and using the closing price of Common Stock as of the date of grant in accordance with FASB ASC Topic 718, would be $1,189,084. The time-lapse RSUs vest in three annual installments of 40%, 30%, 30% respectively following the grant, assuming the NEO continues to meet the requirements for vesting. For Ms. Haller, amounts shown in this column also include 6,904 Centuri RSUs granted to her due to her service on the Centuri Board of Directors. The Centuri RSUs vest on April 30, 2025. The grant date fair value of the Centuri RSUs was based on the closing price of Centuri’s common stock of $24.75 on April 30, 2024. The grant date fair value of the Centuri RSUs granted to Ms. Haller is $170,874. Such amount was determined in accordance with FASB ASC Topic 718, with the grant date fair value calculated by multiplying the closing price of the grant date by the number of Centuri RSUs granted. Award agreements for PSUs and time-lapse RSUs give holders the right to receive dividend equivalent payments as and when dividends are paid on Common Stock, which dividends are reallocated into additional equity awards of the same type and with the same vesting schedule as the original award. (3)For the special PSUs granted in 2024 to Ms. Haller and Mr. Stefani, amounts reflect the aggregate grant date fair value of awards, determined in accordance with FASB ASC Topic 718. As required by SEC disclosure rules, the grant date fair values included in the table were computed by excluding the impact of estimated forfeitures and were based on the probable outcomes and service periods of the performance conditions as of the applicable grant date, with such probability determinations made in accordance with GAAP. As of the grant date, the 2024 special PSUs granted to Ms. Haller and Mr. Stefani were determined, in accordance with GAAP, to not require recognition of an expense, due to performance conditions being dependent upon market conditions, restrictions on the format of the Centuri sale or other disposition that could void the award, and timing/service period for meeting performance conditions. Recognition of an accounting expense occurred for the 25% of the award that was conditioned upon completion of the Centuri IPO, but the remaining 75% of the award remains subject to the considerations described above preventing recognition of an expense pursuant to GAAP. Assuming achievement of the Centuri IPO condition and the condition for sale or other disposition that results in the Company owning less than 20% of Centuri (the highest level of performance), the grant date fair value would be $3,995,428 for Ms. Haller and $1,189,084 for Mr. Stefani. See “Executive Compensation - Compensation Discussion and Analysis - 2024 Executive Officer Compensation - Long-Term Incentive Compensation” for further discussion of the special PSUs granted in 2024 to Ms. Haller and Mr. Stefani. Upon settlement, shares of Common Stock are issued for each earned PSU. There is no predetermined performance period for the special 2024 PSUs granted to Ms. Haller and Mr. Stefani. Additional information about the valuation methodologies and assumptions used in determining the amounts in this column are described in “Note 9 - Share-Based Compensation” included in the footnotes to the consolidated financial statements in our 2024 Annual Report on Form 10-K. (4)Amounts shown in this column represent the annual incentive cash awards paid in 2023, 2024 and 2025 for services performed in 2022, 2023 and 2024, respectively. (5)The aggregate change in the actuarial present value of the NEOs’ accumulated benefit under the Retirement Plan and the SERP for 2024 and the above-market interest (in excess of 120% of the applicable federal long-term rate with compounding) earned by the NEOs on executive deferral plan balances for 2024 are as follows:

  81. Summary Compensation Table (2024, 2023 and 2022)

    Matching contributions to the NEOs under the EDP equal 50% of the amount deferred by each officer up to 3.5% of the officer’s respective annual salary. Since he is not eligible for the Retirement Plan, Mr. Stefani receives a non-elective employer contribution of 3% of his salary to his EIP account and 100% employer matching contributions on the first 7% of his EIP contributions. In 2024, Mr. Stefani received $33,284 in Company-paid non-elective and employer matching contributions to his EIP account and $20,744 in matching contributions to his EDP account. (7)In 2024, the aggregate amount of perquisites and personal benefits for the NEOs was less than $10,000 each. For Mr. Stefani, amounts in this column for 2023 include $35,537 for relocation expense reimbursement as described in the Stefani Employment Agreement. (8)For Ms. Haller, amounts in this column include $146,250 for director fees paid by Centuri, where Ms. Haller serves as a director. (9)Mr. Gabe became an NEO in 2023, so he has no compensation to report for 2022. (10)For Ms. Haller, amount in this column for 2022 relates to a special bonus to recognize her effective leadership of the Company through a year of unprecedented change, as she implemented the Board’s strategic direction to simplify the Company’s business mix to maximize stockholder value. For Mr. Stefani, amount in this column for 2022 relates to the signing bonus he earned when he began employment with the Company. For Mr. Brown and Ms. Williams, amounts in this column for 2022 relate to their portion of the discretionary bonus pool approved by the Board to recognize employees in 2022 for implementing transformational changes to streamline the Company’s business mix, all while keeping customer service and employee experience at exceptionally high levels.

  87. Grants of Plan-Based Awards (2024)

    (2)Amounts shown are rounded to the nearest share. The amounts shown represent the threshold, target and maximum number of shares of Common Stock that could be earned with respect to PSUs granted in 2024 under the long-term performance component of our incentive compensation program. The number of PSUs that will become earned and vested, and the resulting number of shares of Common Stock to be issued, will be determined after completion of the three-year performance period ending December 31, 2026, and the number of shares can range from 50% at threshold to a maximum of 200% of the target number. For the special 2024 PSUs granted to Ms. Haller and Mr. Stefani, there is no predetermined performance period and the number of PSUs that will become earned and vested, and the resulting number of shares of Common Stock to be issued, can range from 0% to 100% (assuming the highest level of performance) of the number of PSUs granted. The performance period for the special 2024 PSUs granted to Mr. Brown is two years, with 50% vesting each on the first and second anniversaries of the grant date, subject to the Company CEO’s determination that Mr. Brown has met the performance conditions, and the final number of special PSUs earned and vested, and the resulting number of shares of Common Stock to be issued, can range from 0% to 100% (assuming the highest level of performance) of the number of special PSUs granted. The initial vesting of Mr. Brown’s special 2024 PSUs occurred in the first quarter of 2025. (3)Amounts shown are rounded to the nearest share. The amounts shown represent the number of time-lapse RSUs that were granted in 2024 under the long-term component of our incentive compensation program. The time-lapse RSUs awarded vest over three years, 40% at the end of the first year and 30% at the end of each of the second and third years, assuming the NEO continues to meet the requirements for vesting, and the initial vesting occurred in the first quarter of 2025. For further details regarding the long-term components of our incentive compensation program, see “Executive Compensation - Compensation Discussion and Analysis - 2024 Executive Officer Compensation - Long-Term Incentive Compensation.” For Ms. Haller, amounts in this column also include Centuri RSUs granted to her due to her service on the Centuri Board of Directors. The Centuri RSUs vest on April 30, 2025. (4)The amounts shown reflect the aggregate grant date fair value (based on the closing price of Common Stock on May 2, 2024 and the closing price of Centuri common stock on April 30, 2024, as applicable) of time-lapse RSUs or PSUs granted on May 2, 2024, and on April 30, 2024 for Ms. Haller’s Centuri RSUs, calculated in accordance with FASB ASC Topic 718. With respect to the PSUs, the amounts represent the grant date fair value assuming performance is achieved at target level. For the special 2024 PSUs, the amounts represent the grant date fair value assuming performance determined in accordance with FASB ASC Topic 718, as described in footnotes (2) and (3) to the “Summary Compensation Table (2024, 2023, and 2022).”

  99. Pension Benefits

    Pension Benefits We offer two defined benefit retirement plans to the NEOs. They include the Retirement Plan, which is available to all employees of Southwest Gas who were hired before January 1, 2022, and the SERP, which is available to officers of Southwest Gas who were hired before January 1, 2022. Benefits under the Retirement Plan are based on (i) years of service with Southwest Gas, up to a maximum of 30 years, and (ii) highest average annual salary over a period of five consecutive years within the final 10 years of service, not to exceed an annual maximum compensation level of $345,000 (in 2024) established by the Internal Revenue Service. Vesting in the Retirement Plan occurs after five years of service with Southwest Gas. The SERP is designed to supplement the benefits under the Retirement Plan to a level of 50-60% of salary. The salary used for the SERP calculation is based on the 12-month average of the highest consecutive 36 months of salary at the time of retirement. Vesting in the SERP occurs at age 55, with 20 years of service, or at age 65 with 10 years of service with Southwest Gas. Upon retirement, the plans will provide a lifetime annuity to the NEOs, with a 50% survivor benefit to their spouses and an option to choose a 75% survivor benefit to their spouses. No lump sum payments are permitted under the plans except when the amount is less than $5,000. Ms. Haller is vested in both plans and would receive full benefits if she were to retire as of the date of this Proxy Statement. Mr. Brown and Ms. Williams are vested only in the Retirement Plan and, if they left the Company as of the date of this Proxy Statement, their accrued benefit under the Retirement Plan would be reduced by 58.56%, assuming benefits commenced at age 55. Mr. Gabe is vested in both plans and if he left the Company as of the date of this Proxy Statement, his benefits would be reduced by 13.25%. Mr. Brown would also receive a limited benefit under the SERP of $24,731 annually. Ms. Williams would also receive a limited benefit under the SERP of $11,210 annually. Mr. Stefani joined the Company after January 1, 2022 and is therefore not eligible for a benefit from either the Retirement Plan or the SERP.

  113. Analysis of Information Presented in the Pay Versus Performance Table

    Analysis of Information Presented in the Pay Versus Performance Table As described in more detail in the section “Executive Compensation - Compensation Discussion and Analysis,” the Company’s executive compensation program reflects a variable pay-for-performance philosophy. While the Company utilizes several performance measures to align executive compensation with Company performance, not all of those Company measures are presented in the Pay Versus Performance table. Moreover, the Company generally seeks to incentivize long-term performance, and therefore does not specifically align the Company’s performance measures with CAP (as computed in accordance with Item 402(v) of Regulation S-K) for a particular year. In accordance with Item 402(v) of Regulation S-K, the Company is providing the following descriptions of the relationships between information presented in the Pay Versus Performance table. In the graphs below, CAP to the PEO for 2022 represents the aggregate CAP to Ms. Haller, the Company’s current CEO, and Mr. Hester, the Company’s former CEO. For 2023 and 2024, CAP to the PEO represents CAP to Ms. Haller, the Company’s current CEO.
