Company Ltd.; Tene Growth Capital 3 (Fund 3 G.P.) Projects Limited Partnership; Tene Investments in Projects 2016 Limited Partnership (the “Record Holder”); and Dr. Ariel Halperin (“Dr. Halperin” and, together with the Record Holder, the “Reporting Persons”), with the United States Securities and Exchange Commission (the “SEC”) on September 13, 2016 (the “Schedule 13D”), relating to the Ordinary Shares, par value NIS 0.04 per share (the “Ordinary Shares”), of Caesarstone Ltd., an Israeli corporation (the “Issuer”). Capitalized terms used herein without definition shall have the meaning set forth in the Schedule 13D.

Item 5 of the Schedule 13D is amended and restated in its entirety by inserting the following information:

(a) – (b)

The following sets forth, as of the date hereof, the aggregate number of Ordinary Shares and percentage of Ordinary Shares beneficially owned by each of the Reporting Persons, as well as the number of shares of Ordinary Shares as to which each Reporting Person has the sole power to vote or to direct the vote, shared power to vote or to direct the vote, sole power to dispose or to direct the disposition, or shared power to dispose or to direct the disposition of, as of the date hereof based on 34,363,211 Ordinary Shares outstanding as of October 23, 2018.

The Record Holder holds 3,452,132 Ordinary Shares of record and, pursuant to the call option granted to the Record Holder by Sdot Yam pursuant to the Term Sheet, has the right to acquire an additional 2,000,000 Ordinary Shares. Pursuant to the Shareholders’ Agreement, the Record Holder also shares the right to direct the voting of 10,440,000 Ordinary Shares beneficially owned by Sdot Yam.

Dr. Halperin is the sole director of Tene III and the major shareholder of Tene III and Tene III Projects. Tene III is the general partner of Tene III Projects, which is the general partner of the Record Holder.
