FOR IMMEDIATE RELEASE

NortonLifeLock Inc.

Possible Combination with Avast PLC (“Avast” or the “Company”)

NortonLifeLock Inc. (“NortonLifeLock”), a global leader in consumer Cyber Safety, notes the announcement by Avast, released earlier today, and confirms that it is in advanced discussions with the board of Avast regarding a possible combination of NortonLifeLock and Avast.

A combination of NortonLifeLock and Avast would bring together two companies with aligned visions, highly complementary business profiles and a joint commitment to innovation that helps protect and empower people to live their digital lives safely. We would draw on the best of both companies to ensure that the combination would benefit our customers, reward our employees and maximise long term value for all shareholders.

The possible combination may be implemented by way of a cash and share offer by NortonLifeLock for the entire issued and to be issued share capital of Avast but, pursuant to Rule 2.5 of the City Code on Takeovers and Mergers (the "Code"), NortonLifeLock reserves the right to vary the form and/or mix of the consideration. This announcement does not amount to an announcement of a firm intention to make an offer under Rule 2.7 of the Code. There can be no certainty that any firm offer for Avast will be made nor as to the terms on which any firm offer might be made.

In accordance with Rule 2.6(a) of the Code, NortonLifeLock must, by not later than 5.00 pm on 11 August 2021 (being 28 days after today’s date), either announce a firm intention to make an offer for Avast in accordance with Rule 2.7 of the Code or announce that it does not intend to make an offer for Avast, in which case the announcement will be treated as a statement to which Rule 2.8 of the Code applies. This deadline can be extended with the consent of the Panel on Takeovers and Mergers (the "Panel") in accordance with Rule 2.6(c) of the Code.

A further announcement will be made as appropriate.

Disclosure requirements of the Code

Under Rule 8.3(a) of the Code, any person who is interested in 1 per cent. or more of any class of relevant securities of an offeree company or of any securities exchange offeror (being any offeror other than an offeror in respect of which it has been announced that its offer is, or is likely to be, solely in cash) must make an Opening Position Disclosure following the commencement of the offer period and, if later, following the announcement in which any securities exchange offeror is first identified.

An Opening Position Disclosure must contain details of the person's interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror(s). An Opening Position Disclosure by a person to whom Rule 8.3(a) applies must be made by not later than 3.30 pm (London time) on the 10^th business day following the commencement of the offer period and, if appropriate, by not later than 3.30 pm (London time) on the 10^th business day following the announcement in which any securities exchange offeror is first identified. Relevant persons who deal in the relevant securities of the offeree company or of a securities exchange offeror prior to the deadline for making an Opening Position Disclosure must instead make a Dealing Disclosure.

Under Rule 8.3(b) of the Code, any person who is, or becomes, interested in 1 per cent. or more of any class of relevant securities of the offeree company or of any securities exchange offeror must make a Dealing Disclosure if the person deals in any relevant securities of the offeree company or of any securities exchange offeror. A Dealing Disclosure must contain details of the dealing concerned and of the person's interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror(s), save to the extent that these details have previously been disclosed under Rule 8. A Dealing Disclosure by a person to whom Rule 8.3(b) applies must be made by not later than 3.30 pm (London time) on the business day following the date of the relevant dealing.

If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire or control an interest in relevant securities of an offeree company or a securities exchange offeror, they will be deemed to be a single person for the purpose of Rule 8.3.

Opening Position Disclosures must also be made by the offeree company and by any offeror and Dealing Disclosures must also be made by the offeree company, by any offeror and by any persons acting in concert with any of them (see Rules 8.1, 8.2 and 8.4 of the Code).
