The acceptance period expired at midnight (CEST) on September 17, 2026. During the acceptance period, 7,568,145 Nagarro shares were tendered into the Offer. This represents approximately 61.15%1 of the total share capital and voting rights of Nagarro. In addition, Persistent already secured a stake of approximately 22.10%1 in Nagarro under a share purchase agreement with Lantano Beteiligungen GmbH (“Lantano”). Together, the tendered shares and the shares secured from Lantano represent approximately 83.25%1 of the total share capital and voting rights of Nagarro. The minimum acceptance threshold of 50% plus one share required for the Offer to be completed has thus been exceeded. According to the German Securities Acquisition and Takeover Act (WpÜG), Nagarro shareholders who have not yet tendered their shares can still accept the Offer at the same cash consideration of EUR 81.00 per share by tendering their shares within the additional acceptance period, which 1: excluding treasury shares © 2026 Persistent Systems Ltd. All rights reserved. 1 will begin on September 23, 2026, and end at midnight (CEST) on October 6, 2026. Persistent will disclose the final number of shares tendered following the expiry of the additional acceptance period. Sandeep Kalra, Chief Executive Officer and Executive Director, Persistent Systems Limited: “We have offered Nagarro shareholders an attractive opportunity to realize full and immediate value. The success of the offer confirms its appeal and the strategic logic behind combining Persistent and Nagarro. We now look forward to completing the remaining steps toward closing, so we may start building the global AI-led digital engineering leader we envisioned together.” Potential delisting might reduce liquidity Following the consummation of the Offer and acting on a taking private strategy, Persistent intends to terminate the admission of Nagarro shares to trading on the regulated market (Prime Standard) of the Frankfurt Stock Exchange and trading on the open market of other stock exchanges as soon as practicable and legally feasible. The termination of admission to trading on the regulated market would result in Nagarro being excluded from the SDAX and a reduction in liquidity of Nagarro shares. Pursuant to the Business Combination Agreement, Nagarro’s Management Board is, subject to its fiduciary duties, willing to support the delisting of the Nagarro shares. The offer document and a non-binding English translation are available at www.galaxy-offer.com. Persistent expects the transaction to close by the end of Q1 CY27, subject to only a limited number of outstanding regulatory approvals.
