NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION, IN WHOLE OR IN PART, IN, INTO OR FROM ANY JURISDICTION WHERE TO DO SO WOULD CONSTITUTE A VIOLATION OF THE RELEVANT LAWS OF SUCH JURISDICTION FOR IMMEDIATE RELEASE 13 April 2021 RECOMMENDED CASH OFFER for G4S PLC by ATLAS UK BIDCO LIMITED (a newly incorporated entity that is indirectly controlled by Allied Universal) COMPULSORY ACQUISITION OF G4S SHARES 1. Introduction On 6 April 2021, Atlas UK Bidco Limited (“Allied Bidco”), a newly incorporated entity that is indirectly controlled by Allied Universal Topco LLC, announced that its recommended cash offer (the “Offer”) for G4S plc (“G4S” or the “Company”) had become unconditional in all respects. Allied Bidco is pleased to announce that as at 1.00 p.m. (London time) on 12 April 2021, it had received valid acceptances under the Offer in respect of a total of 1,410,398,516 G4S Shares representing approximately 90.25 per cent. of the existing issued ordinary share capital of G4S. 2. Compulsory acquisition As Allied Bidco has now received acceptances under the Offer in respect of, and/or otherwise acquired, not less than 90 per cent. in value of the G4S Shares to which the Offer relates and of the voting rights carried by those shares, Allied Bidco will exercise its rights in accordance with sections 974 to 991 of the Act to acquire compulsorily the remaining G4S Shares in respect of which the Offer has not been accepted as contemplated by the Offer Document. Allied Bidco will shortly despatch formal compulsory acquisition notices under sections 979 and 980 of the Act (the "Compulsory Acquisition Notices") to G4S Shareholders who have not yet accepted the Offer. These notices will set out Allied Bidco's intention to apply the provisions of section 979 of the Act to acquire compulsorily any remaining G4S Shares in respect of which the Offer has not been accepted on the same terms as the Offer. On the expiry of six weeks from the date of the Compulsory Acquisition Notices, the G4S Shares held by those G4S Shareholders who have not accepted the Offer will be acquired compulsorily by Allied Bidco on the same terms as the Offer. The consideration to which those G4S Shareholders will be entitled will be held by G4S as trustee on behalf of those G4S Shareholders who have not accepted the Offer. 3. Procedure for acceptance of the Offer G4S Shareholders may still accept the Offer, which remains open for acceptance until further notice. As mentioned below, settlement of consideration to which any accepting G4S Shareholder is entitled under the Offer shall be effected by the issue of cheques or CREST payments within 14 days of receipt of the valid acceptance, whereas G4S Shareholders who have not accepted the Offer will be subject to the compulsory acquisition process which is expected to take a minimum of six weeks. G4S Shareholders who have not yet accepted the Offer are urged to do so as soon as possible in accordance with the following procedures: If you hold your G4S Shares in certificated form (that is, not in CREST), you should complete and return the Form of Acceptance accompanying the Offer Document as soon as possible. If you hold your G4S Shares in uncertificated form (that is, in CREST), you should ensure that an Electronic Acceptance is made by you or on your behalf and that the TTE instruction settles as soon as possible. If you hold your G4S Shares as a CREST sponsored member, you should contact your CREST sponsor as only your CREST sponsor will be able to send the necessary TTE instruction to Euroclear. G4S ADR Holders who wish to participate in the Offer should contact their Depositary. G4S VP Holders who wish to participate in the Offer should contact Danske Bank. Full details on how to accept the Offer are set out in paragraph 16 of Part II of the Offer Document and Parts D and E of Appendix 1 of the Offer Document. The Offer Document is available on Allied Universal’s website (www.securityservicesthereforyou.com) and on G4S’s website (www.g4s.com/investors/offers). For the avoidance of doubt, the contents of the websites referred to in this announcement are not incorporated into and do not form part of this announcement. Further copies of the Offer Document and the Form of Acceptance may be obtained by contacting Link Group on 0371 664 0321. 4. Settlement While the Offer remains open for acceptance, settlement of consideration to which any accepting G4S Shareholder is entitled under the Offer shall be effected by the issue of cheques or CREST payments within 14 days of the date of receipt of such acceptance which is valid and complete in all respects. Non-assenting G4S Shareholders who do not accept the Offer will not receive payment until after compulsory acquisition has been implemented. 5. Other 5.1 Unless the context otherwise requires and save to the extent superseded in this announcement, the definitions and rules of interpretation used in the offer document published by Allied Bidco on 5 January 2021 (the “Offer Document”) shall also apply in this announcement. The percentages of G4S Shares referred to in this announcement are based upon a figure of 1,562,715,442 G4S Shares in issue as at close of business in London on 12 April 2021. G4S Shareholders with any questions relating to this announcement or the completion and return of the Form of Acceptance or the making of an Electronic Acceptance (as the case may be) should telephone the Link Group on 0371 664 0321 or, if calling from outside the United Kingdom, +44 (0) 371 664 0321. Calls are charged at the standard geographic rate and will vary by provider. The helpline is open between 9.00 am – 5.30 pm, Monday to Friday excluding public holidays in England and Wales. Please note that Link Group cannot provide any financial, legal or tax advice and calls may be recorded and monitored for security and training purposes. G4S has its primary listing on the London Stock Exchange (until at least 5 May 2021) and has a secondary listing on the Nasdaq exchange in Copenhagen. On 19 March 2021, Nasdaq approved the removal from trading of G4S's shares from Nasdaq Copenhagen A/S ("Nasdaq") and official listing. The last day of trading on Nasdaq will be 16 April 2021.

Any decision by G4S Shareholders in respect of, or other response to, the Offer should be made only on the basis of the information contained in the Offer Document and, in respect of G4S Shares held in certificated form, the Form of Acceptance. G4S Shareholders are advised to read the Offer Document and the Form of Acceptance carefully because they contain important information in relation to the Offer.

Additional information for US G4S Shareholders and G4S ADR Holders The Offer is being made to G4S Shareholders resident in the United States in reliance on, and compliance with, Section 14(e) of the US Exchange Act, and Regulation 14E thereunder, as a “Tier II” tender offer (as set forth in Rule 14d-1(d) under the US Exchange Act) and otherwise in accordance with the requirements of the City Code. The Offer is being made in the United States by Allied Bidco and no one else. The Offer relates to the shares of a United Kingdom incorporated company and is subject to United Kingdom disclosure and other procedural requirements, which are different from certain United States disclosure and procedural requirements. Furthermore, the payment and settlement procedure with respect to the Offer will comply with the relevant United Kingdom rules, which differ from US payment and settlement procedures, particularly with regard to the date of payment of consideration. The Offer is being made in compliance with all applicable laws and regulations, including, to the extent applicable, Section 14(e) of the US Exchange Act and Regulation 14E thereunder as a “Tier II” tender offer (as set forth in Rule 14d-1(d) under the US Exchange Act) and otherwise in accordance with the requirements of the City Code. In accordance with normal United Kingdom practice and consistent with Rule 14e-5(b) under the US Exchange Act, Allied Bidco, certain affiliated companies and their nominees or brokers (acting as agents) may make certain purchases of, or arrangements to purchase, shares in G4S other than pursuant to the Offer, during the period in which the Offer would remain open for acceptance (or, if the Offer is implemented by way of a Scheme, until the date on which the Scheme becomes effective, lapses or is otherwise withdrawn). If such purchases or arrangements to purchase were to be made, they would be made outside the United States either in the open market at prevailing prices or in private transactions at negotiated prices and would comply with applicable law, including, to the extent applicable, the US Exchange Act. Any information about such purchases will be disclosed as required in the UK, will be reported to a Regulatory Information Service and will be available on the London Stock Exchange website at www.londonstockexchange.com. Certain financial information included in this announcement and the Offer Document has been prepared in accordance with accounting standards applicable in the United Kingdom, and may not be comparable to financial information of United States companies or companies whose financial statements are prepared in accordance with generally accepted accounting principles in the United States. The receipt of consideration by a US G4S Shareholder or a G4S ADR Holder for the transfer of its G4S Shares or its G4S ADRs, as applicable, pursuant to the Offer may be a taxable transaction for United States federal income tax purposes and under applicable United States state and local, as well as non-US and other, tax laws. Each G4S Shareholder and G4S ADR Holder is urged to consult their independent professional adviser immediately regarding the tax consequences of the Offer, and acceptance of the Offer, applicable to them, including under applicable United States federal, state and local, as well as non-US and other, tax laws. It may be difficult for US G4S Shareholders or G4S ADR Holders to enforce their rights and claims arising out of the US federal securities laws, since G4S is organised under the laws of England and Wales, and some or all of its officers and directors are residents of countries other than the United States. It may not be possible to sue a non-US company or its directors, officers or affiliates, in a non-US court for violations of US securities laws. It may be difficult to compel a non-US company and its directors, officers and affiliates to subject themselves to the jurisdiction and judgment of a United States court. Neither the US Securities and Exchange Commission nor any United States state securities commission has approved or disapproved the Offer, or passed upon the fairness of the Offer or passed upon the adequacy or accuracy of this document. Any representation to the contrary is a criminal offence in the United States. Additional Information for Danish G4S Shareholders and G4S VP Holders This document does not constitute an offer document under Danish securities laws and consequently is not required to be nor has been filed with or approved by the Danish Financial Supervisory Authority as this document has not been prepared in the context of a public takeover offer in Denmark within the meaning of the Danish Capital Markets Act or any executive orders issued pursuant thereto.

In particular, the ability of persons who are not resident in the United Kingdom to accept the Offer or to execute and deliver the Form of Acceptance, 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 Offer disclaim any responsibility or liability for the violation of such restrictions by any person. This announcement has been prepared for the purpose of complying with English law and the City Code and the information disclosed may not be the same as that which would have been disclosed if this announcement had been prepared in accordance with the laws of jurisdictions outside the United Kingdom. Unless otherwise determined by Allied Universal or required by the City Code, and permitted by applicable law and regulation, the Offer is not being made available, directly or indirectly, in, into or from a Restricted Jurisdiction or any other jurisdiction where to do so would violate the laws in that jurisdiction and no person may accept the Offer by any use, 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 including the United States or any other jurisdiction where to do so would constitute a violation of the laws of that jurisdiction and the Offer may not be capable of acceptance by any such use, means, instrumentality or facilities.

Cautionary note regarding forward-looking statements This announcement (including information incorporated by reference in the announcement), oral statements made regarding the Offer, and other information published by Allied Universal or Allied Bidco contains certain forward looking statements with respect to the financial condition, results of operations and businesses of Allied Universal and G4S and their respective groups, and certain plans and objectives of Allied Universal with respect to the Enlarged Group. All statements other than statements of historical fact are, or may be deemed to be, forward looking statements. Forward looking statements are statements of future expectations which are prospective in nature and are not based on historical facts, but rather on management’s current expectations, projections and assumptions and involve known and unknown risks and uncertainties that could cause actual results, performance or events to differ materially from those expressed or implied in these statements. Forward looking statements include, among other things, statements concerning the potential exposure of Allied Universal, the Allied Universal Group, G4S and/or the G4S Group to market risks and statements expressing management’s expectations, beliefs, estimates, forecasts, projections and assumptions, including as to future potential cost savings, synergies, earnings, cash flow, return on average capital employed, production, divestitures and prospects. Often, but not always, these forward looking statements are identified by their use of terms and phrases such as “anticipate” or “does not anticipate”, “believe”, “estimate”, “forecast”, “expect” or “does not expect”, “is expected”, “is subject to”, “goals”, “intend”, “objectives”, “outlook”, “plan”, “budget”, “scheduled”, “probably”, “project”, “risks”, “seek”, “target” or variations of such words and phrases and statements that certain actions, events or results “may”, “could”, “should”, “would”, “might” or “will” be taken, occur or be achieved. There are a number of factors that could affect the future operations of Allied Universal, the Allied Universal Group, G4S and/or the G4S Group and that could cause results and developments to differ materially from those expressed or implied in the forward looking statements included in this announcement, including (without limitation): (a) changes in demand for Allied Universal’s and/or G4S’s products; (b) currency fluctuations; (c) loss of market share and industry competition; (d) risks associated with the identification of suitable properties, acquirors and targets, and successful negotiation and completion of such transactions; (e) changes in macroeconomic or trading conditions; (f) the impact of COVID-19; and (g) changes in government and regulation including in relation to health and safety. Other unknown or unpredictable factors could cause actual results to differ materially from those in the forward looking statements. Such forward looking statements should therefore be construed in the light of such factors. All forward looking statements contained in this announcement are expressly qualified in their entirety by the cautionary statements contained or referred to in this section. Although Allied Universal and Allied Bidco believe that the expectations reflected in such forward looking statements are reasonable, Allied Universal, Allied Bidco and their respective associates, directors, officers and advisers provide no representation, assurance or guarantee that the occurrence of the events expressed or implied in any forward looking statements in this announcement will actually occur. Readers should not place undue reliance on forward looking statements. Each forward looking statement speaks only as of the date of this announcement. None of Allied Universal, Allied Bidco or the Allied Universal Group undertakes any obligation, and expressly disclaims any intention or obligation, to publicly update or revise any forward looking statement as a result of new information, future events or otherwise, except to the extent legally required (including under the United Kingdom Listing Rules and the Disclosure and Transparency Rules of the FCA). In light of these risks, results could differ materially from those stated, implied or inferred from the forward looking statements contained in this announcement. No forecasts or estimates No statement in this announcement is intended as a profit forecast, profit estimate or quantified financial benefits statement for any period and no statement in this announcement should be interpreted to mean that cash flow from operations, free cash flow, earnings or earnings per share for Allied Universal, Allied Bidco, G4S or the Enlarged Group, as appropriate, for the current or future financial years would necessarily match or exceed the respective historical published cash flow from operations, free cash flow, earnings or earnings per share for Allied Universal, Allied Bidco or G4S as appropriate or to mean that the Enlarged Group’s earnings in the first 12 months following the Offer, or in any subsequent period, would necessarily match or be greater than those of Allied Bidco or G4S for the relevant preceding financial period or any other period.
