for all of the equity securities in Rakon (the Lock-Up Agreements). The Lock-Up Agreements
relate to an aggregate of 94,671,815 RAK Shares. Copies of each of the Lock-Up Agreements
were attached to the relevant disclosure filed by Bourns on 12 January 2026.

On 9 February 2026, Bourns made a full cash takeover offer under the Takeovers Code to acquire
all of the equity securities in Rakon at a price of $1.55 per equity security (the Offer). A copy of
the offer document dated 9 February 2026 was provided to NZX on that date.

As at the end of day on 10 February 2026:

(a) 66,655,134 RAK Shares subject to the Lock-Up Agreements had been accepted under
the Offer. As a result, for the purposes of section 278 of the Financial Markets Conduct
Act 2013, the nature of Bourns’ relevant interest in those RAK Shares has changed; and

of, in aggregate, 108,424,031 RAK Shares. Payment for those RAK Shares will be made in
