Litigation Related to the Transactions
On April 28, 2022, in connection with the Transactions, a purported individual stockholder of the Company filed a complaint in the United States District
Court for the Southern District of New York, captioned Stein v. Vidler Water Resources, Inc., et al, No. 1:22-cv-3468 (Stein), naming as defendants the Company and each member of the Companys board of directors
as of the date of the Merger Agreement. On May 2, 2022, one additional case was filed by a purported individual stockholder of the Company in the same court, captioned Casey v. Vidler Water Resources, et al, No. 1:22-cv-3528
(Casey). On May 2, 2022 and May 6, 2022, two additional cases were filed by purported individual stockholders of the Company in the United States District Court for the Eastern District of New York, captioned,
respectively, Rabinovich v. Vidler Water Resources, Inc, et al, No. 1:22-cv-2509 (Rabinovich), and Koh v. Vidler Water Resources, Inc., et al, No. 1:22-cv-2631 (Koh). On May 12,
2022, three additional cases were filed by purported individual stockholders of the Company in the United States District Court for the District of Delaware, the United Stated District Court for the Eastern District of Pennsylvania, and the United
States District Court for the Eastern District of New York, captioned, respectively, Wilhelm v. Vidler Water Resources, Inc., et al, No. 1:22-cv-00631 (Wilhelm), Waterman v. Vidler Water Resources, Inc., et al,
No. 2:22-cv-01854 (Waterman), and Whitfield v. Vidler Water Resources, Inc., et al, No. 1:22-cv-02788 (Whitfield). On May 13, 2022, one additional case was filed by a purported individual stockholder of
the Company in the United States District Court for the Southern District of New York, captioned Taylor v. Vidler Water Resources, Inc., at al, No. 1:22-cv-03909 (Taylor). The Stein, Casey, Rabinovich, Koh, Wilhelm, Waterman,
Whitfield, Taylor, and any similar subsequently filed cases involving the Company, the Companys board of directors or any committee thereof, and/or any of the Companys directors or officers relating directly or indirectly to the Merger
Agreement, the Transaction, or any related transaction, are referred to as the Transaction Litigations.
The Transaction Litigations
filed to date generally allege that the Schedule 14D-9 filed by the Company with the SEC on April 27, 2022, in connection with the Transaction is materially incomplete and misleading because it allegedly fails to disclose purportedly material
information, including relating to the sale process leading to the Transactions, the Companys financial projections, and the analyses performed by Duff & Phelps Opinion Practice, Kroll LLC, in connection with the Transactions. The
Transaction Litigations assert violations of Section 14(e), Section 14(d), and Section 20(a) of the Securities Exchange Act of 1934, as amended (the Exchange Act), and Rule 14d-9 promulgated thereunder. The Transaction
Litigations seek, among other things: an injunction enjoining consummation of the Transaction, rescission of the Merger Agreement, dissemination of a revised Schedule 14D-9, damages, a declaration that the Company and the board of directors violated
Sections 14(e), 14(d), and 20(a) of the Exchange Act and Rule 14d-9 promulgated thereunder, costs of the action, including plaintiffs attorneys fees and experts fees and expenses, and any other relief the court may deem just and
proper.
In addition, on May 2, 2022 and May 10, 2022, the Company received demand letters from purported individual stockholders of the Company
alleging that the Schedule 14D-9 omits purportedly material information relating to the Transaction (the Demand Letters).
