The Sales Agents may sell Common Shares in the manner described in Section 2.01(b) herein. The Company acknowledges and agrees that (i) there can be no assurance that the Sales Agents will be successful in selling Common Shares and (ii) the Sales Agents will incur no liability or obligation to the Company or any other Person if it does not sell Common Shares for any reason other than a failure by such Sales Agent to use its commercially reasonable efforts, consistent with its normal trading and sales practices to sell such Common Shares as required under this Section 2.01. In acting hereunder, the Sales Agents will be acting as agent for the Company and not as principal.

(b) Method of Offer and Sale. The Common Shares may be offered and sold by any method permitted by law and deemed to be an “at the market offering” as defined in Rule 415 under the Securities Act.

The Company shall have responsibility for maintaining records with respect to the aggregate number and the aggregate Sales Price of Common Shares sold and for otherwise monitoring the availability of Common Shares for sale under the Registration Statement and for ensuring that the aggregate number and aggregate Sales Price of Common Shares offered and sold does not exceed, and the price at which any Shares are offered or sold is not lower than, the aggregate number and aggregate Sales Price of Common Shares, i.e., the Maximum Program Amount, and the Floor Price authorized from time to time by the Board of Directors of the Company.

(a) Issuance Notice. On any Trading Day during the Commitment Period, the Company may deliver an Issuance Notice to a Sales Agent, subject to the satisfaction of the conditions set forth in Sections 5.01 and 5.02; provided, however, that, notwithstanding anything in this Agreement to the contrary, the Sales Agents shall have no further obligations with respect to any Issuance Notice if and to the extent the number of Common Shares to be sold pursuant thereto, together with the aggregate number of the Common Shares previously sold under this Agreement shall exceed the Maximum Program Amount.

(b) Delivery of Issuance Notice. An Issuance Notice shall be deemed delivered on the Trading Day that it is received by facsimile or e-mail (and the Company confirms either such notice by telephone (including voice-mail message)) by the Sales Agents to the individuals listed on Schedule 1 hereto. No Issuance Notice may be delivered other than on a Trading Day during the Commitment Period.

(c) Acceptance of Issuance Notice. If the Sales Agent agrees to the terms of such Issuance Notice, then the Sales Agent shall promptly deliver to the Company by email a notice (each, an “Acceptance”) confirming the terms as set forth in such Issuance Notice or setting forth the modified terms for such proposed Issuance Notice as agreed by the Company and the Sales Agent, as the case may be, whereupon such Issuance Notice and related Acceptance shall become a binding agreement between the Company and the Sales Agent.

(d) Floor Price. The Sales Agent shall not sell Common Shares below the Floor Price during any Selling Period, as such Floor Price may be adjusted by the Company at any time during any Selling Period upon notice to the relevant Sales Agent and confirmation to the Company.

(e) Trading Guidelines. The Company hereby acknowledges and agrees that the Affiliates of each Sales Agent, subject to compliance with Regulation M under the Exchange Act, may make markets in the Common Stock or other securities of the Company, in connection with which they may buy and sell, as agent or principal, for long or short account, shares of Common Stock or other securities of the Company, at the same time such Sales Agent is acting as agent pursuant to this Agreement.

(f) Limitation. The Company agrees that any offer to sell, any solicitation of an offer to buy, or any sales of Common Shares by the Company shall be effected only by or through one Sales Agent on any Trading Day.

Section 2.04 Use of Free Writing Prospectuses. The Company represents and agrees that, unless it obtains the prior written consent of the Sales Agents (which may be provided via electronic mail), until the termination of this Agreement, it has not made and will not make any offer relating to the Common Shares that would constitute an “issuer free writing prospectus” (as defined in Rule 433 under the Act) or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 under the Act) other than any Permitted Free Writing Prospectus. Any such free writing prospectus relating to the Common Shares consented to by the Sales Agents is hereinafter referred to as a “Permitted Free Writing Prospectus”.

Section 2.05 Settlements. Subject to the provisions of Article V, on or before each Settlement Date, the Company will cause EQ Shareowner Services, its transfer agent, to electronically transfer the Common Shares being sold by crediting the Sales Agent or its designee’s account at DTC through its Deposit/Withdrawal At Custodian (DWAC) System, or by such other means of delivery as may be mutually agreed upon by the parties hereto and concurrently with the receipt of such Common Shares, which in all cases shall be freely tradable, transferable, registered shares in good deliverable form, each Sales Agent will deliver the related Issuance Price in same day funds delivered to an account designated by the Company prior to the Settlement Date. If the Company defaults in its obligation to deliver Common Shares on a Settlement Date, the Company agrees that it will (a) hold each Sales Agent harmless against any loss, claim, damage or expense (including, without limitation, penalties, interest and reasonable legal fees and

6

expenses), as incurred, arising out of or in connection with such default by the Company, and (b) pay to each Sales Agent any Selling Commission to which it would otherwise have been entitled absent such default. The individuals listed on Schedule 1 hereto shall be the contact persons for all matters related to the settlement of the transfer of Common Shares through the DWAC System for purposes of this Section 2.05.

Section 2.06 Material Non-Public Information. Notwithstanding any other provision of this Agreement, each Sales Agent shall not be obligated to sell any Common Shares hereunder during any period in which it reasonably believes that the Company is in possession of material non-public information. Notwithstanding any other provision of this Agreement, the Company shall not offer, sell or deliver, or request the offer or sale, of any Common Shares pursuant to this Agreement and, by notice to each Sales Agent given by telephone (confirmed promptly by e-mail), shall cancel any instructions for the offer or sale of any Common Shares, (a) during any period in which the Company is in possession of material non-public information; and (b) at any time from and including the date on which the Company shall issue a press release containing, or shall otherwise publicly announce, its earnings, revenues or other results of operations (an “Earnings Announcement”) through and including the time that is 24 hours after the time that the Company files a Quarterly Report on Form 10-Q or an Annual Report on Form 10-K that includes consolidated financial statements as of and for the same period or periods, as the case may be, covered by such Earnings Announcement.

Section 2.07 Exemption from Regulation M. If any Sales Agent reasonably believes that the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange Act (applicable to “actively traded securities” as defined under Regulation M under the Exchange Act) are not satisfied with respect to the Company or the Common Shares, such Sales Agent shall promptly notify the Company of such belief and sales of Common Shares under this Agreement shall be suspended until that or other exemptive provisions have been satisfied in the reasonable judgment of the parties. If, either immediately prior to delivery of an Issuance Notice or during a Selling Period, the Company reasonably believes that the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange Act are not satisfied with respect to the Company or the Common Shares, it shall promptly notify each Sales Agent of such belief and sales of Common Shares under this Agreement shall be suspended until that or other exemptive provisions have been satisfied in the reasonable judgment of both parties. Notwithstanding the foregoing, in the event the Company engages a Sales Agent for a sale of Common Shares in an transaction that would constitute a “distribution,” within the meaning of Rule 100 of Regulation M under the Exchange Act or a “block” within the meaning of Rule 10b-18(a)(5) under the Exchange Act, the Company will provide such Sales Agent, at such Sales Agent’s request and upon reasonable advance notice to the Company, on or prior to the Settlement Date, the opinions of counsel, accountants’ letters and officers’ certificates pursuant to Sections 4.07, 4.08 and 4.09 hereof, each dated the Settlement Date, and such other documents and information as the Sales Agent shall reasonably request, and the Company and the Sales Agent will agree to compensation that is customary for the Sales Agent with respect to such transaction.

Any pro forma financial information and the related notes thereto included or incorporated by reference in the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus have been prepared in accordance with the applicable requirements of the Securities Act and the Exchange Act, as applicable, and the assumptions underlying such pro forma financial information are reasonable and are set forth in the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus at the respective dates or for the respective periods to which they apply and no other historical or pro forma financial statements or supporting schedules are required to be included or incorporated by reference in the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus under the Securities Act or the rules and regulations of the Commission.

Since the respective dates as of which information is given in the Prospectus, the Company has not been advised of any fraud, whether or not material, that involves management or other employees who have a significant role in the internal controls of the Company and each of its Subsidiaries.

12

Subsidiaries against theft, damage, destruction, acts of vandalism and all other risks customarily insured against. All policies of insurance insuring the Company or any of its Material Subsidiaries or their respective businesses, assets, employees, officers and directors are in full force and effect; the Company and its Material Subsidiaries are in compliance with the terms of such policies and instruments in all material respects; and there are no claims by the Company or any of its Material Subsidiaries, that individually or in the aggregate are material to the Company and its Material Subsidiaries taken together as a whole, under any such policy or instrument as to which any insurance company is denying liability or defending under a reservation of rights clause; and, except as set forth in the Prospectus, neither the Company nor any of its Material Subsidiaries has been refused any insurance coverage sought or applied for. The Company has no reason to believe that it or any of its Material Subsidiaries will not be able (i) to renew its existing insurance coverage as and when such policies expire or (ii) to obtain comparable coverage from similar institutions as may be necessary or appropriate to conduct its business as now conducted and at a cost that would not reasonably be expected to have a Material Adverse Effect.

ARTICLE VI

INDEMNIFICATION AND CONTRIBUTION

Section 6.01 Indemnification by the Company. The Company agrees to indemnify and hold harmless each Sales Agent, its officers, directors, and each Person, if any, who controls such Sales Agent within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (collectively, the “Indemnified Persons”), from and against any and all losses, claims, damages or liabilities, and any action or proceeding in respect thereof, to which any such Indemnified Person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Prospectus or any other prospectus relating to the Common Shares (including a Free Writing Prospectus), or any amendment or supplement thereto, or any preliminary prospectus, or arise out of, or are based upon, any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of the Prospectus or any amendment or supplement thereto or any preliminary prospectus, in light of the circumstances in which they were made) not misleading, except insofar as the same are made in reliance upon and in conformity with information provided by such Sales Agent furnished in writing to the Company by the Sales Agent expressly for use therein where it is understood and agreed that as of the date of this Agreement the only written information furnished to the Company by the Sales Agents is the legal and marketing names of the Sales Agents as included on the front cover page and the back cover page of the Prospectus Supplement, and the Company shall reimburse such Indemnified Person for any reasonable legal and other expenses incurred thereby in investigating or defending or preparing to defend against any such losses, claims, damages or liabilities, or actions or proceedings in respect thereof, as such expenses are incurred.

Section 6.02 Indemnification by the Sales Agents. Each Sales Agent agrees severally, and not jointly, to indemnify and hold harmless the Company, its officers who have signed the Registration Statement, directors and each Person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in Section 6.01 above, but only with respect to written information provided by such Sales Agent furnished in writing to the Company by such Sales Agent expressly for use therein, where it is understood and agreed that as of the date of this Agreement the only written information furnished to the Company by the Sales Agents is the legal and marketing names of the Sales Agents as included on the front cover page and the back cover page of the Prospectus Supplement, and such Sales Agent shall reimburse the Company, its officers, directors, employees and agents, and each controlling Person of the Company for any reasonable legal and other expenses incurred thereby in investigating or defending or preparing to defend against any such losses, claims, damages or liabilities, or actions or proceedings in respect thereof, as such expenses are incurred.

Section 6.03 Conduct of Indemnification Proceedings. As promptly as reasonably practicable after receipt by any Person (an “Indemnified Party”) of notice of any claim or the commencement of any action in respect of which indemnity may be sought pursuant to Section 6.01 or 6.02, the Indemnified Party shall, if a claim in respect thereof is to be made against the Person against whom such indemnity may be sought (an “Indemnifying Party”), notify the Indemnifying Party in writing of the claim or the commencement of such action. In the event an Indemnified Party shall fail to give such notice as provided in this Section 6.03 and the Indemnifying Party to whom notice was not given was unaware of the proceeding to which such notice would have related and was materially prejudiced by the failure to give such notice, the indemnification provided for in Sections 6.01 or 6.02 shall be reduced to the extent of any actual prejudice resulting from such failure to so notify the Indemnifying Party; provided, that the failure to notify the Indemnifying Party shall not relieve it from any liability that it may have to an Indemnified Party otherwise than under Section 6.01 or 6.02. If any such claim or action shall be brought against an Indemnified Party, the Indemnifying Party shall be entitled to participate therein, and, to the extent that it wishes, jointly with any other similarly notified Indemnifying Party, to assume the defense thereof with counsel reasonably satisfactory to the Indemnified Party. After notice from the Indemnifying Party to the Indemnified Party of its election to assume the

23

defense of such claim or action, the Indemnifying Party shall not be liable to the Indemnified Party for any legal or other expenses subsequently incurred by the Indemnified Party in connection with the defense thereof other than reasonable costs of investigation; provided that the Indemnified Party shall have the right to employ separate counsel to represent the Indemnified Party, but the fees and expenses of such counsel shall be for the account of such Indemnified Party unless (a) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of such counsel, (b) such Indemnified Party reasonably concludes that representation of both parties by the same counsel would be inappropriate due to actual or potential conflicts of interest with the Company, (c) the Indemnifying Party has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person, or (d) the Indemnified Party shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person, it being understood, however, that the Indemnifying Party shall not, in connection with any one such claim or action or separate but substantially similar or related claims or actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (together with appropriate local counsel) at any time for all Indemnified Parties or for fees and expenses that are not reasonable. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any claim or pending or threatened proceeding in respect of which the Indemnified Party is or could have been a party and indemnification could have been sought hereunder by such Indemnified Party unless such settlement includes an unconditional release of each such Indemnified Party from all losses, claims, damages or liabilities arising out of such claim or proceeding and such settlement does not admit or constitute an admission of fault, guilt, failure to act or culpability on the part of any such Indemnified Party. Whether or not the defense of any claim or action is assumed by an Indemnifying Party, such Indemnifying Party will not be subject to any liability for any settlement made without its prior written consent, which consent will not be unreasonably withheld. Notwithstanding the foregoing sentence, if at any time an Indemnified Party shall have requested an Indemnifying Party to reimburse the Indemnified Party for fees and expenses of counsel as contemplated by this Section 6.03, the Indemnifying Person agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such Indemnifying Party of the aforesaid request and (ii) such Indemnifying Party shall not have reimbursed the Indemnified Party in accordance with such request prior to the date of such settlement.

Section 6.04 Contribution.

(a) If for any reason the indemnification provided for in this Article VI is unavailable to the Indemnified Parties in respect of any losses, claims, damages or liabilities referred to herein, then each Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages or liabilities as between the Company, on the one hand, and the relevant Sales Agent, on the other hand, in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand and the relevant Sales Agent on the other hand from the offering of the Common Shares to which such losses, claims, damages or liabilities relate. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each Indemnifying Party shall contribute to such amount paid or payable by such Indemnifying Party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and of the relevant Sales Agent in connection with such statements or omissions, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and by the relevant Sales Agent, on the other, shall be deemed to be in the same proportion as the total net proceeds from the sale of Common Shares (before deducting expenses) received by the Company bear to the total commissions received by the relevant Sales Agent in respect thereof. The relative fault of the Company, on the one hand, and of the relevant Sales Agent, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on one hand or by the relevant Sales Agent on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(b) The Company and each Sales Agent agree that it would not be just and equitable if contribution pursuant to this Section 6.04 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an Indemnified Party as a result of the losses, claims, damages or liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any reasonable legal or other

24

expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 6.04, the relevant Sales Agent shall in no event be required to contribute any amount in excess of the commissions received by it under this Agreement. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 6.04 each officer, director, employee and agent of the relevant Sales Agent, and each Indemnified Person, shall have the same rights to contribution as such Sales Agent, and each director of the Company, each officer of the Company who signed the Registration Statement, and each Person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company. The obligations of the Company and the relevant Sales Agent under this Article VI shall be in addition to any liability that the Company and the relevant Sales Agent may otherwise have.

ARTICLE VII

Section 7.04 Liability; Provisions that Survive Termination. If this Agreement is terminated pursuant to this Article VII, such termination shall be without liability of any party to any other party except as provided in Section 9.02 and for the Company’s obligations in respect of all prior Issuance Notices, and provided further that in any case the provisions of Article VI, Article VIII and Article IX shall survive termination of this Agreement without limitation.

ARTICLE VIII

Ladies and Gentlemen:

We are acting as counsel to Southwest Gas Holdings, Inc., a Delaware corporation (the “Company”), in connection with its Registration Statement on Form S-3 (File No. 333-275774) (the “Registration Statement”) filed with the United States Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), which became effective upon filing on November 28, 2023, the related prospectus included therein (the “Base Prospectus”), and the prospectus supplement filed with the Commission on August 6, 2024 pursuant to Rule 424(b)(5) promulgated under the Securities Act (the “Prospectus Supplement”). This opinion is rendered in connection with the proposed issuance and sale by the Company of shares of the Company’s common stock, par value $1.00 per share (the “Common Stock”), having an aggregate offering price of up to $340,000,000 (the “Placement Shares”), pursuant to the terms of that certain Equity Distribution Agreement, dated August 6, 2024 (the “Equity Distribution Agreement”), by and among the Company, J.P. Morgan Securities LLC and Wells Fargo Securities, LLC and in the manner described in the Prospectus Supplement. The Placement Shares will be issued from time to time in public offerings at market or negotiated prices under Rule 415 of the Securities Act.

As counsel for the Company, we have examined the Equity Distribution Agreement, the Registration Statement, the Base Prospectus, the Prospectus Supplement, the Company’s Certificate of Incorporation (the “Charter”), the Company’s Amended and Restated Bylaws, as amended, as well as originals or copies, certified or otherwise identified to our satisfaction, of such documents, corporate records, certificates of public officials and other instruments as we have deemed necessary for the purposes of rendering this opinion, and we are familiar with the proceedings taken and proposed to be taken by the Company in connection with the authorization, issuance and sale of the Placement Shares. In our examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals and the conformity with the originals of all documents submitted to us as copies. We also have assumed that the Placement Shares will not be issued in violation of the ownership limit contained in the Charter. This opinion letter is given, and all statements herein are made, in the context of the foregoing.

This opinion letter is based as to matters of law solely on Delaware General Corporation Law. We express no opinion herein as to any other laws, statutes, ordinances, rules or regulations. As used herein, the term “Delaware General Corporation Law” includes the statutory provisions contained therein, all applicable provisions of the Delaware Constitution and reported judicial decisions interpreting these laws.

Based upon, subject to and limited by the foregoing, we are of the opinion that the Placement Shares have been duly and validly authorized and upon issuance, delivery and payment therefor in the manner contemplated by the Registration Statement, the Base Prospectus and the Prospectus Supplement, will be legally issued, fully paid and nonassessable.

This opinion is furnished to you in connection with the filing by the Company of a Current Report on Form 8-K relating to the offer and sale of the Placement Shares, which Form 8-K will be incorporated by reference into the Registration Statement, the Base Prospectus and the Prospectus Supplement and may not be relied upon for any other purpose without our express written consent. No opinion may be implied or inferred beyond the opinion expressly stated. This opinion is given as of the date hereof, and we assume no obligation to advise you of any changes in applicable law or any facts or circumstances that come to our attention after the date hereof that may affect the opinion contained herein.

We hereby consent to the filing of this opinion as an exhibit to the above-described Current Report on Form 8-K and to the reference to our firm contained under the heading “Legal Matters” in the Prospectus Supplement. In giving this consent, we do not admit that we are in the category of persons whose consent is required by Section 7 of the Securities Act or the rules and regulations promulgated by the Commission.
