ADVA Optical Networking SE: Acorn HoldCo, Inc., lowers minimum acceptance threshold of the public exchange offer to all shareholders of ADVA

Munich, Germany, 10 January 2022. On 12 November 2021, Acorn HoldCo, Inc. published the Offer Document to its voluntary public takeover offer (exchange offer) to the shareholders of ADVA Optical Networking SE ("ADVA") to acquire all non-par value bearer shares in ADVA held by them. Completion of the takeover offer is subject to, inter alia, the offer being accepted for at least 70% of all ADVA shares entitled to voting rights existing as of 31 October 2021, as further described in the offer document.

Acorn HoldCo, Inc. has informed ADVA on 10 January 2022, 22.38 hours (local time Frankfurt am Main) that it intends to lower the minimum acceptance threshold for its takeover offer from 70% to 60%. The notification also stated that there will be no further changes to the exchange offer or the offer conditions. If the acceptance threshold is not reached at the end of the acceptance period, the notice says that the offer will fail. Subsequently, ADVA consented to the lowering of the threshold. Acorn HoldCo, Inc. intends to publish the offer document amended accordingly, inter alia, on Internet at https://www.acorn-offer.com. For further details, especially to the method of counting the shares relevant for the minimum acceptance threshold, reference is being made to the amended offer document.

As a result of lowering the minimum acceptance threshold, the acceptance period originally expiring on 12 January 2022, 24.00 hours (local time Frankfurt am Main) will, by law, be extended by two weeks. It will now expire on 26 January 2022, 24.00 hours (local time Frankfurt am Main).

The management board and supervisory board will publish a supplementary reasoned statement on the modified offer in a timely manner pursuant to the provisions of German law.

The business combination continues to be subject to the completion of the offer conditions, especially to the lowered minimum acceptance threshold of 60% and to the receipt of all foreign investment approvals.
