Item 1 Comment:
This statement constitutes Amendment No. 14 to the Schedule 13D (as amended, the "Schedule 13D") relating to the shares of the common stock, par value $1.00 per share (the "Common Stock"), of Southwest Gas Holdings, Inc., a Delaware corporation (the "Issuer"), and hereby amends the Schedule 13D originally filed with the Securities and Exchange Commission (the "SEC") on June 3, 2022. All capitalized terms contained herein but not otherwise defined shall have the meanings ascribed to such terms in the Schedule 13D. The percentages set forth on the cover pages hereto are based on 72,182,840 shares of Common Stock outstanding as of October 31, 2025, as disclosed by the Issuer in its Form 10-Q for the quarterly period ended September 30, 2025. | ||
| Item 4. | Purpose of Transaction | |
Item 4 of the Schedule 13D is hereby amended by adding the following:
In connection with the execution of the Amended and Restated Cooperation Agreement, dated as of October 14, 2025 (referred to as the "2025 Agreement"), the Issuer and the Reporting Persons had previously agreed to enter into a customary form of registration rights agreement with respect to the shares of Common Stock beneficially owned by the Reporting Persons. On November 26, 2025, the Issuer and the Reporting Persons entered into a Registration Rights Agreement (the "Registration Rights Agreement"), pursuant to which the Issuer granted certain customary shelf, underwritten offering and piggy-back registration rights to the Reporting Persons subject to the terms and conditions set forth therein. The Registration Rights Agreement supersedes the registration rights described in Exhibit B of the 2025 Agreement.
The foregoing description of the Registration Rights Agreement is qualified in its entirety by reference to the Registration Rights Agreement, a copy of which is included hereto as Exhibit 8. | ||
| Item 6. | Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer | |
The information set forth in Item 4 of this Schedule 13D is hereby incorporated by reference into this Item 6. | ||
| Item 7. | Material to be Filed as Exhibits. | |
Item 7 of the Schedule 13D is hereby amended by the addition of the following exhibit:
Exhibit 8. Registration Rights Agreement, dated November 26, 2025, by and among Southwest Gas Holdings, Inc. and the Reporting Persons (incorporated by reference to Exhibit 10.1 to Southwest Gas Holdings, Inc.'s Current Report on Form 8-K filed by with the Securities and Exchange Commission on November 26, 2025). | ||
| SIGNATURE | |
After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
