Confirmation of Intention to Float on the London Stock Exchange

Following the announcement by Darktrace plc (the "

Company

", and together with

Darktrace Holdings Limited and its subsidiaries and subsidiary undertakings, the "

Group

or "

Darktrace

") on 12 April 2021 of its expected intention to float, the Company today

confirms its intention to undertake an initial public offering (the "

IPO

" or the "

Offer

and certain details of the Offer.

The Company intends to apply for admission of its ordinary shares (the "

") to the

premium segment of the Official List of the FCA and to trading on the London Stock

Exchange's Main Market for listed securities (together, "

Admission

").

The final offer price in respect of the Offer (the "

early May 2021.

Confirmation of Offer Details:

A premium listing on the Official List of the FCA and admission to trading on the

Main Market for listed securities of the London Stock Exchange.

The Offer will comprise a primary offer to raise proceeds to accelerate new product

development, drive broader awareness of the Company's products globally and to

provide balance sheet strength and financial flexibility. There also is also expected to

be a secondary sell-down of existing ordinary shares by certain existing shareholders.

The Offer will be a targeted offering to institutional investors outside the United

States pursuant to Regulation S and to QIBs in the United States pursuant to Rule

20% of its issued share capital and expects that it would be eligible for inclusion in

the FTSE UK indices. In addition, it is expected that Shares representing up to a

further 15% of the Offer will be made available pursuant to an over-allotment option.

In connection with the Offer, each of the Company, its directors and all employees and

existing shareholders with a shareholding greater than 0.5% are expected to agree to

customary lock-up arrangements (subject to customary exceptions) restricting the

disposal of Shares for a period of time following Admission.

and such transactions may be effected on any stock market, over-the-counter market, stock

exchange or otherwise and may be undertaken at any time during the period commencing

on the date of commencement of conditional dealings of the Shares on the London Stock

Exchange and ending no later than 30 calendar days thereafter. However, there will be no

obligation on Jefferies International Limited or any of its agents to effect stabilising

exercisable in whole or in part, upon notice by Jefferies International Limited, at any time

calendar day after the commencement of conditional trading of the

Shares on the London Stock Exchange. Any Over-Allotment Shares made available

distributions declared, made or paid on the Shares, will be purchased on the same terms

and conditions as the Shares being issued or sold in the Offer and will form a single class

Information to Distributors

Solely for the purposes of the product governance requirements of Chapter 3 of the FCA

Handbook Product Intervention and Product Governance Sourcebook (the "UK Product

Governance Requirements"), and disclaiming all and any liability, whether arising in tort,

contract or otherwise, which any "manufacturer" (for the purposes of the UK Product

Governance Requirements) may otherwise have with respect thereto, the Shares have been

subject to a product approval process, which has determined that the Shares are: (i)

compatible with an end target market of retail investors and investors who meet the

criteria of professional clients and eligible counterparties, each defined in paragraph 3 of

Privacy

the FCA Handbook Conduct of Business Sourcebook; and (ii) eligible for distribution

through all permitted distribution channels (the "Target Market Assessment").

Notwithstanding the Target Market Assessment, "distributors" (for the purposes of the UK

Product Governance Requirements) should note that: the price of the Shares may decline

and investors could lose all or part of their investment; the Shares offer no guaranteed

income and no capital protection; and an investment in the Shares is compatible only with

investors who do not need a guaranteed income or capital protection, who (either alone or

in conjunction with an appropriate financial or other adviser) are capable of evaluating the

merits and risks of such an investment and who have sufficient resources to be able to

bear any losses that may result therefrom. The Target Market Assessment is without

prejudice to any contractual, legal or regulatory selling restrictions in relation to the Offer.

Furthermore, it is noted that, notwithstanding the Target Market Assessment, Jefferies

International Limited, Joh. Berenberg, Gossler & Co. KG, London Branch, KKR Capital

Markets

Partners LLP

, Needham & Company, LLC and Piper Sandler & Co. will only

procure investors who meet the criteria of professional clients and eligible counterparties.

For the avoidance of doubt, the Target Market Assessment does not constitute: (a) an

assessment of suitability or appropriateness for the purposes of Chapters 9A or 10A

respectively of the FCA Handbook Conduct of Business Sourcebook; or (b) a

recommendation to any investor or group of investors to invest in, or purchase, or take

any other action whatsoever with respect to the Shares.

Each distributor is responsible for undertaking its own target market assessment in respect

of the Shares and determining appropriate distribution channels.
