Amsterdam, the Netherlands - Today, Koninklijke Philips N.V. (“Royal Philips”) announces that it has successfully completed the accelerated bookbuild offering to institutional investors of 16.22 million shares in Philips Lighting N.V. (“Philips Lighting”) at a price of EUR 32.10 per share (the “Offering”), realizing total proceeds of approximately EUR 520.7 million. This transaction reduces Royal Philips’ stake in Philips Lighting’s issued share capital from 29.59% to 18.0%.

As part of this transaction, Philips Lighting will repurchase 2,200,000 shares in the Offering and intends to cancel these shares. After such cancellation, Royal Philips’ shareholding in Philips Lighting is expected to represent 18.3% of Philips Lighting’s issued share capital. Philips Lighting will not receive any proceeds from the Offering.

The transaction is expected to settle on March 1, 2018. Royal Philips has agreed to a lock-up in respect of its remaining stake in Philips Lighting until the publication of Philips Lighting’s Q1 results on April 26, 2018 (subject to limited exceptions and the Joint Bookrunners’ right to waive the lock-up restrictions).

The intended transaction is in line with Royal Philips’ stated objective to fully sell down its stake in Philips Lighting.
