Forward-looking statements

The information (including information incorporated by reference) and documents on the Web Page may contain statements which are, or may be deemed to be, “forward-looking statements” which are prospective in nature. All statements, other than statements of historical fact, may be forward-looking statements. They are based on current expectations and projections about future events and are therefore subject to risks and uncertainties which could cause actual results to differ materially from the future results expressed or implied by the forward-looking statements. Often, but not always, forward-looking statements can be identified by the use of forward-looking words such as “plans”, “expects”, “is expected”, “is subject to”, “budget”, “pro forma”, “scheduled”, “estimates”, “forecasts”, “intends”, “anticipates”, “believes”, “targets”, “aims”, “projects” or words or phrases of similar substance (or the negative thereof), as well as variations of such words and phrases or statements that certain actions, events or results “may”, “could”, “should”, “would”, “might” or “will” be taken, occur or be achieved. Such statements are qualified in their entirety by the inherent risks and uncertainties surrounding future expectations.

Among other things, the information (including information incorporated by reference) and documents on the Web Page may contain forward-looking statements regarding the Transaction and may include statements about the benefits of the Transaction, expected future earnings, revenues and cost savings and other such items, based on NortonLifeLock’s and the Company’s plans, estimates and projections. These forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from those predicted in any such forward-looking statements. Such factors include, but are not limited to, the possibility that the Transaction will not be pursued, general business and economic conditions globally, industry trends, competition, changes in government and other regulation, changes in political and economic stability, disruptions in business operations due to reorganisation activities, interest rate and currency fluctuations, the failure to satisfy the conditions of the Transaction if and when implemented (including approvals or clearances from regulatory and other agencies and bodies) on a timely basis or at all, the inability of the enlarged group to realise successfully any anticipated synergy benefits when (and if) the Transaction is implemented, the inability of the (post-Transaction) enlarged group to integrate successfully NortonLifeLock’s and the Company’s operations when (and if) the Transaction is implemented and the enlarged group incurring and/or experiencing unanticipated costs and/or delays or difficulties relating to the Transaction when (and if) it is implemented. Additional information concerning these and other risk factors is contained in the Risk Factors sections of NortonLifeLock’s most recent reports on Form 10-K and Form 10-Q the contents of which are not incorporated by reference into, nor do they form part of, this Web Page.

All forward-looking statements involve risks and uncertainties that could significantly affect expected results and are based on certain key assumptions. Many factors could cause actual results to differ materially from those projected or implied in any forward-looking statements. Due to such uncertainties and risks, readers are cautioned not to place undue reliance on such forward-looking statements, which speak only as at the date that they were made. NortonLifeLock and its members, directors, officers, employees, advisers, agents, affiliates and representatives expressly disclaim any intention or obligation to update or revise any forward-looking or other statements contained in the information available on the Web Page, whether as a result of new information, future events or otherwise, except as required by applicable law.

Neither NortonLifeLock, nor any of its members, directors, officers, employees, advisers, agents, affiliates or representatives, provides any representation, assurance or guarantee that the occurrence of the events expressed or implied in any forward-looking statements in the information available on the Web Page will actually occur.

No forward-looking or other statements have been reviewed by the auditors of NortonLifeLock, unless otherwise explicitly stated. All subsequent oral or written forward-looking statements attributable to NortonLifeLock, or any of its members, directors, officers, employees, advisers, agents, affiliates or representatives, are expressly qualified in their entirety by the cautionary statement above.

No offer or solicitation

The information contained on the Web Page is for information purposes only and is not intended to and does not constitute, or form any part of, an offer to sell or the solicitation of an offer to subscribe for or an invitation to subscribe for any securities or the solicitation of any vote or approval in any jurisdiction pursuant to the Transaction or otherwise, nor shall there be any sale, issuance, subscription or transfer of securities in any jurisdiction in contravention of applicable law or regulation. In particular, this Web Page is not an offer of securities for sale in the United States. No offer of securities shall be made in the United States absent registration under the U.S. Securities Act of 1933, as amended (the “Securities Act”), or pursuant to an exemption from, or in a transaction not subject to, such registration requirements. Any securities issued in the Transaction are anticipated to be issued in reliance upon available exemptions from such registration requirements pursuant to Section 3(a)(10) of the Securities Act. The Transaction will be made solely by means of the scheme document to be published by the Company in due course, or (if applicable) pursuant to an offer document to be published by NortonLifeLock, which (as applicable) would contain the full terms and conditions of the Transaction. Any decision in respect of, or other response to, the Transaction, should be made only on the basis of the information contained in such document(s). As explained below, if NortonLifeLock ultimately seeks to implement the Transaction by way of a takeover offer, that offer will be made in compliance with applicable U.S. laws and regulations.

This Web Page does not constitute a prospectus or a prospectus exempted document.

Notice to U.S. Investors in Avast

The Transaction relates to the acquisition of the securities of an English company, and is expected to be implemented pursuant to a scheme of arrangement under English law. A transaction implemented by means of a scheme of arrangement is not subject to the tender offer rules of the U.S. Exchange Act of 1934, as amended. Accordingly, the Transaction is subject to disclosure requirements and practices applicable in the UK to schemes of arrangement, which differ from the disclosure and procedural requirements of U.S. tender offer rules. Any financial information included in this Web Page may have been prepared in accordance with accounting standards applicable in the United Kingdom and thus may not be comparable to financial information of U.S. companies or companies whose financial statements are prepared in accordance with generally accepted accounting principles in the United States. If NortonLifeLock exercises its right in the future to implement the Transaction by way of a takeover offer, that offer will be made in compliance with applicable U.S. laws and regulations

It may be difficult for U.S. holders of the Company shares to enforce their rights and claims arising out of the U.S. federal securities laws, since the Company is located in a country other than the United States, and some or all of its officers and directors are residents of a country other than the United States. U.S. holders of the Company’s shares may not be able to sue a non-U.S. company or its officers or directors in a non-U.S. court for violations of the U.S. securities laws. Further, it may be difficult to compel a non-U.S. company and its affiliates to subject themselves to a U.S. court's judgement.

No Profit Forecasts or Estimates

 No statement in this Web Page is intended as, or is to be construed as, a profit forecast or estimate for any period and no statement in this Web Page should be interpreted to mean that earnings or earnings per ordinary share, for NortonLifeLock or the Company, respectively for the current or future financial years would necessarily match or exceed the historical published earnings or earnings per ordinary share for NortonLifeLock or the Company, respectively.
