RECOMMENDED CASH ACQUISITION

of

Osirium Technologies plc ("Osirium")

SailPoint Technologies UK Ltd ("Bidco")

(a wholly-owned indirect subsidiary of SailPoint Parent, L.P.)

to be effected by means of a Scheme of Arrangement under Part 26 of the Companies Act 2006

COURT SANCTION OF SCHEME OF ARRANGEMENT

On 30 August 2023, the boards of Osirium and Bidco announced that they had reached agreement on the terms of a recommended cash acquisition pursuant to which Bidco proposes to acquire the entire issued and to be issued share capital of Osirium (the "Acquisition"). The Acquisition is being implemented by means of a Court-sanctioned scheme of arrangement under Part 26 of the Companies Act 2006 (the "Scheme"), full details of which were sent, or made available, to the Osirium Shareholders in the circular dated 18 September 2023 (the "Scheme Document").

On 12 October 2023, the Scheme was approved by the requisite majority of Scheme Shareholders at the Court Meeting and the Resolution relating to the implementation of the Scheme was approved by the requisite majority of Osirium Shareholders at the General Meeting.

Osirium is pleased to announce that the High Court of Justice in England and Wales has today sanctioned the Scheme pursuant to which the Acquisition is being implemented.

It is anticipated that the Effective Date of the Scheme will be 30 October 2023, which is when a copy of the Court Order is expected to be delivered to the Registrar of Companies (together with a copy of the Scheme and all documents required to be annexed thereto). There has been no change to the expected timetable of principal events for the Acquisition set out in the announcement made by Osirium in relation to the Acquisition on 12 October 2023.

The last day of dealings in, and for the registration and transfer of, and disablement in CREST of, Osirium Shares is expected to be tomorrow, 27 October 2023. The Scheme Record Time is expected to be 6.00 p.m. on 27 October 2023. An application has been made for the suspension of trading in Osirium Shares on AIM, and such suspension is expected to take effect at 7.30 a.m. on 30 October 2023. The cancellation of Osirium Shares from admission to trading on AIM has also been applied for and will, subject to the Scheme becoming Effective, take effect at 7.00 a.m. on 31 October 2023.

On the Effective Date, share certificates in respect of Scheme Shares will cease to be valid documents of title and entitlements to Scheme Shares held in uncertificated form in CREST will be cancelled.

A further announcement will be made when the Scheme has become Effective.

Full details of the Acquisition are set out in the Scheme Document.

Capitalised terms used in this announcement, unless otherwise defined, shall have the meanings given to them in the Scheme Document.

This announcement has been prepared in accordance with and for the purpose of complying with English law, the Takeover Code, the AIM Rules, the Market Abuse Regulation and the Disclosure Guidance and Transparency Rules and information disclosed may not be the same as that which would have been prepared in accordance with the laws of jurisdictions outside England.

The availability of the Acquisition to Osirium Shareholders who are not resident in and citizens of the UK may be affected by the laws of the relevant jurisdictions in which they are located or of which they are citizens. Persons who are not resident in the UK should inform themselves of, and observe, any applicable legal or regulatory requirements of their jurisdictions. In particular, the ability of persons who are not resident in the United Kingdom to vote their Osirium Shares with respect to the Scheme at the Court Meeting, or to appoint another person as proxy to vote at the Court Meeting on their behalf, may be affected by the laws of the relevant jurisdictions in which they are located. Any failure to comply with the applicable restrictions may constitute a violation of the securities laws of any such jurisdiction. To the fullest extent permitted by applicable law, the companies and persons involved in the Acquisition disclaim any responsibility or liability for the violation of such restrictions by any person. Further details in relation to Overseas Shareholders will be contained in the Scheme Document.

Unless otherwise determined by Bidco or required by the Takeover Code, and permitted by applicable law and regulation, the Acquisition will not be made available, directly or indirectly, in, into, from, or by the use of mails or any means or instrumentality (including, but not limited to, facsimile, e-mail or other electronic transmission, telex or telephone) of interstate or foreign commerce of, or of any facility of a national, state or other securities exchange of, any Restricted Jurisdiction where to do so would violate the laws in that jurisdiction and no person may vote in favour of the Scheme by any such use, means, instrumentality or from within a Restricted Jurisdiction or any other jurisdiction if to do so would constitute a violation of the laws of that jurisdiction. Copies of this announcement and any formal documentation relating to the Acquisition are not being, and must not be, directly or indirectly, mailed or otherwise forwarded, distributed or sent in or into or from any Restricted Jurisdiction and persons receiving such documents (including, without limitation, agents, custodians, nominees and trustees) must not mail or otherwise forward, distribute or send it in or into or from any Restricted Jurisdiction. Doing so may render invalid any related purported vote in respect of the Acquisition.

Further details in relation to overseas shareholders will be included in the Scheme Document.

Notice to U.S. Osirium Shareholders

The Acquisition relates to the shares of an English company and is being made by means of a scheme of arrangement provided for under the laws of England and Wales. A transaction effected by means of a scheme of arrangement is not subject to the tender offer or proxy solicitation rules under the U.S. Securities Exchange Act of 1934 (the "U.S. Exchange Act"). Accordingly, the Acquisition is subject to the disclosure requirements and practices applicable in the UK to schemes of arrangement which differ from the disclosure requirements of the U.S. tender offer and proxy solicitation rules. The financial information included in this announcement has been prepared in accordance with generally accepted accounting principles of 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, in the future, Bidco exercises its right to implement the Acquisition by way of an Offer, which is to be made into the United States, such Offer will be made in compliance with the applicable U.S. laws and regulations.

It may be difficult for U.S. holders of Osirium Shares to enforce their rights and any claim arising out of the U.S. federal laws, since Bidco and Osirium are located in a non-U.S. jurisdiction, and some or all of their officers and directors may be residents of a non-U.S. jurisdiction. U.S. holders of Osirium 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.

In accordance with normal UK practice and pursuant to Rule 14e-5(b) of the U.S. Exchange Act, SailPoint, Thoma Bravo or their nominees, or their brokers (acting as agents), may from time to time make certain purchases of, or arrangements to purchase, Osirium Shares outside of the U.S., other than pursuant to the Acquisition, until the date on which the Acquisition becomes Effective, lapses or is otherwise withdrawn. Also, in accordance with Rule 14e-5(b) of the U.S. Exchange Act, Cavendish will continue to act as an exempt principal trader in Osirium shares on the London Stock Exchange. These purchases may occur either in the open market at prevailing prices or in private transactions at negotiated prices. Any information about such purchases will be disclosed as required in the United Kingdom, will be reported to a Regulatory Information Service and will be available on the London Stock Exchange website, www.londonstockexchange.com.

U.S. Osirium Shareholders also should be aware that the transaction contemplated herein may have tax consequences in the U.S. and, that such consequences, if any, are not described herein. U.S. Osirium Shareholders are urged to consult with legal, tax and financial advisers in connection with making a decision regarding this transaction.

Forward Looking Statements

This announcement (including information incorporated by reference in this announcement), oral statements made regarding the Acquisition, and other information published by Bidco and Osirium contain statements which are, or may be deemed to be, "forward-looking statements". Forward-looking statements are prospective in nature and are not based on historical facts, but rather on current expectations and projections of the management of Bidco and Osirium 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.

The forward-looking statements contained in this announcement include statements relating to the expected effects of the Acquisition on Bidco and Osirium (including their future prospects, developments and strategies), the expected timing and scope of the Acquisition and other statements other than historical facts. Often, but not always, forward-looking statements can be identified by the use of forward-looking words such as "prepares", "plans", "expects" or "does not expect", "is expected", "is subject to", "budget", "projects", "synergy", "strategy", "scheduled", "goal", "estimates", "forecasts", "cost-saving", "intends", "anticipates" or "does not anticipate", or "believes", or 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. Forward looking statements may include statements relating to the following: (i) future capital expenditures, expenses, revenues, earnings, synergies, economic performance, indebtedness, financial condition, dividend policy, losses and future prospects; (ii) business and management strategies and the expansion and growth of Bidco's, Osirium's, any member of the SailPoint Group's or any member of the Osirium Group's operations and potential synergies resulting from the Acquisition; and (iii) the effects of global economic conditions and governmental regulation on Bidco's, Osirium's, any member of the SailPoint Group's or any member of the Osirium Group's business.

Although Bidco and Osirium believe that the expectations reflected in such forward-looking statements are reasonable, Bidco and Osirium can give no assurance that such expectations will prove to be correct. By their nature, forward-looking statements involve risk and uncertainty because they relate to events and depend on circumstances that will occur in the future. There are a number of factors that could cause actual results and developments to differ materially from those expressed or implied by such forward-looking statements.

These factors include, but are not limited to: the ability to complete the Acquisition; the ability to obtain requisite regulatory and shareholder approvals and the satisfaction of other Conditions on the proposed terms and schedule; changes in the global political, economic, business and competitive environments and in market and regulatory forces; changes in future exchange and interest rates; changes in tax rates; future business combinations or disposals; changes in general economic and business conditions; changes in the behaviour of other market participants; changes in the anticipated benefits from the proposed transaction not being realised as a result of changes in general economic and market conditions in the countries in which Bidco and Osirium operate, weak, volatile or illiquid capital and/or credit markets, changes in tax rates, interest rate and currency value fluctuations, the degree of competition in the geographic and business areas in which Bidco and Osirium operate and changes in laws or in supervisory expectations or requirements. Other unknown or unpredictable factors could cause actual results to differ materially from those expected, estimated or projected in the forward-looking statements. If any one or more of these risks or uncertainties materialises or if any one or more of the assumptions proves incorrect, actual results may differ materially from those expected, estimated or projected. Such forward-looking statements should therefore be construed in the light of such factors. Neither Bidco nor Osirium, nor any of their respective associates or directors, officers or advisers, provides any representation, assurance or guarantee that the occurrence of the events expressed or implied in any forward-looking statements in this announcement will actually occur. You are cautioned not to place any reliance on these forward-looking statements.

Specifically, statements of estimated cost savings and synergies related to future actions and circumstances which, by their nature, involve risks, uncertainties and contingencies. As a result, the cost savings and synergies referred to may not be achieved, may be achieved later or sooner than estimated, or those achieved could be materially different from those estimated. Due to the scale of the Osirium Group, there may be additional changes to the Osirium Group's operations. As a result, and given the fact that the changes relate to the future, the resulting cost synergies may be materially greater or less than those estimated.

Other than in accordance with their legal or regulatory obligations, neither Bidco nor Osirium is under any obligation, and Bidco and Osirium expressly disclaim any intention or obligation, to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

Dealing and Opening Position Disclosure Requirements

Under Rule 8.3(a) of the Takeover Code, any person who is interested in 1% 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) of the Takeover Code applies must be made by no later than 3.30 pm (London time) on the 10th business day following the commencement of the offer period and, if appropriate, by no later than 3.30 pm (London time) on the 10th 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 Takeover Code, any person who is, or becomes, interested in 1% 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 no 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).

Details of the offeree and offeror companies in respect of whose relevant securities Opening Position Disclosures and Dealing Disclosures must be made can be found in the Disclosure Table on the Panel's website at www.thetakeoverpanel.org.uk, including details of the number of relevant securities in issue, when the offer period commenced and when any offeror was first identified.
