“Final Results of the Offer and Completion of the Merger

The Offer and related withdrawal rights expired at one minute after 11:59 p.m., Eastern time, on June 18, 2025 and were not further extended. Broadridge Corporate Issuer Solutions, LLC, the depositary and paying agent for the Offer, advised Purchaser that, as of the expiration of the Offer, a total of 44,503,838 Shares were validly tendered and not validly withdrawn, representing approximately 72.90% of the Shares outstanding as of the expiration of the Offer.

As of the expiration of the Offer, the number of Shares validly tendered in accordance with the terms of the Offer and not validly withdrawn satisfied the Minimum Tender Condition (as defined in the Merger Agreement), and all other conditions to the Offer were satisfied or waived. Immediately after the expiration of the Offer, Purchaser irrevocably accepted for payment all Shares validly tendered and not validly withdrawn, and expects to promptly pay for such Shares pursuant to the terms of the Offer and the Merger Agreement.

As a result of its acceptance of the Shares tendered pursuant to the Offer and in accordance with Section 251(h) of the DGCL, Purchaser owns a number of Shares that is greater than the percentage of Shares that would be required to adopt the Merger Agreement by a vote of Kronos’ stockholders. Accordingly, pursuant to the Merger Agreement, Parent and Purchaser completed the acquisition of Kronos on June 20, 2025 by consummating the Merger pursuant to the Merger Agreement without a vote of Kronos’ stockholders in accordance with Section 251(h) of the DGCL. At the Effective Time, each outstanding Share (other than (i) Shares held in the treasury of Kronos immediately prior to the Effective Time, which will be canceled without any conversion thereof and no consideration will be delivered in exchange therefor, (ii) any Shares held by stockholders or owned by beneficial owners who are entitled to demand, and have properly demanded, appraisal of such Shares in accordance with the DGCL, and have neither failed to perfect nor effectively withdrawn or lost such rights prior to the Effective Time and (iii) Shares that were owned by Parent, Purchaser or any other subsidiary of Parent at the commencement of the Offer and is owned by Parent, Purchaser or any other subsidiary of Parent immediately prior to the Effective Time) was cancelled and converted into the right to receive the Offer Price, without interest and in each case, less any applicable withholding taxes, from Purchaser.

Prior to the opening of trading on the Nasdaq Stock Market LLC (“Nasdaq”) on June 20, 2025, all Shares ceased trading, and following the consummation of the Merger, all Shares will be delisted from Nasdaq and deregistered under the Securities Exchange Act of 1934, as amended.”
