RECOMMENDED ACQUISITION

of

ONTHEMARKET PLC ("OnTheMarket" or the "Company")

by

COSTAR UK LIMITED ("CoStar UK"),

(a wholly-owned indirect subsidiary of CoStar Group, Inc. ("CoStar"))

to be effected by means of a Scheme of Arrangement

Publication of Scheme Document

On 19 October 2023, the Boards of CoStar UK and OnTheMarket announced that they had reached agreement on the terms of a recommended all cash offer pursuant to which CoStar UK, a wholly-owned indirect subsidiary of CoStar, would acquire the entire issued and to be issued share capital of OnTheMarket for 110 pence per share (the "Acquisition").

The Acquisition is to be effected by means of a Court-sanctioned scheme of arrangement under Part 26 of the Companies Act 2006 (the "Scheme").

Publication and posting of Scheme Document

OnTheMarket is pleased to announce that a circular in relation to the Scheme (the "Scheme Document"), containing, amongst other things, a letter from the Chair of OnTheMarket, the full terms and Conditions of the Scheme, an explanatory statement, an expected timetable of principal events, notices convening the Court Meeting and the General Meeting and details of the actions to be taken by OnTheMarket Shareholders, will be published today on OnTheMarket's website at https://plc.onthemarket.com/recommended-cash-acquisition/.

Subject to any restrictions relating to persons resident in Restricted Jurisdictions, hard copies of the Forms of Proxy or the Forms of Instruction for the Court Meeting and the General Meeting are being posted to OnTheMarket Shareholders or OnTheMarket Nominee Service Holders (as applicable). Hard copies of the Scheme Document, or a letter and/or e-mail giving details of OnTheMarket's website at https://plc.onthemarket.com/recommended-cash-acquisition/ where the Scheme Document may be accessed, are also being sent to OnTheMarket Shareholders and OnTheMarket Nominee Service Holders (as applicable) in accordance with the notice provisions of the Company's articles of association and the relevant OnTheMarket Shareholder's or OnTheMarket Nominee Service Holder's communication preferences.

For information purposes only, the Scheme Document will also be sent, or made available, to OnTheMarket Share Plan Participants and persons with information rights.

Capitalised terms in this announcement, unless otherwise defined herein, have the same meanings as set out in the Scheme Document.

Recommendation from the OnTheMarket Directors

The OnTheMarket Directors, who have been so advised by Zeus as to the financial terms of the Acquisition, consider the terms of the Acquisition to be fair and reasonable. In providing advice to the OnTheMarket Directors, Zeus has taken into account the commercial assessments of the OnTheMarket Directors. Zeus is providing independent financial advice to the OnTheMarket Directors for the purposes of Rule 3 of the Code.

Accordingly, the OnTheMarket Directors recommend unanimously that Scheme Shareholders vote (or procure the voting) in favour of the Scheme at the Court Meeting and that OnTheMarket Shareholders vote (or procure the voting) in favour of the Special Resolution at the General Meeting (or, if CoStar UK exercises its right to implement the Acquisition by way of a Takeover Offer, to accept, or procure the acceptance of, such Takeover Offer), as each OnTheMarket Director holding OnTheMarket Shares has irrevocably undertaken to do in respect of their own beneficial holdings, amounting, in aggregate, to 185,625 OnTheMarket Shares (representing, in aggregate, approximately 0.23 per cent. of the OnTheMarket Shares in issue on 3 November 2023, being the latest practicable date prior to the publication of this announcement (the "Last Practicable Date")).

Action required by shareholders - Notices of the Court Meeting and the General Meeting

As described in the Scheme Document, to become Effective, the Scheme will require, amongst other things, the approval of Scheme Shareholders at the Court Meeting and OnTheMarket Shareholders at the separate General Meeting by the requisite majorities and, following receipt of such approvals, the sanction of the Court. The Scheme is also subject to the satisfaction or, where applicable, waiver of the Conditions and further terms that are set out in the Scheme Document.

Notices of the Court Meeting and the General Meeting, which will be held at the offices of Eversheds Sutherland (International) LLP at One Wood Street, London, EC2V 7WS on 4 December 2023, are set out in the Scheme Document. The Court Meeting will commence at 10.00 a.m. (London time) and the General Meeting at 10.15 a.m. (London time) (or as soon as reasonably practicable thereafter as the Court Meeting shall have been concluded or adjourned).

It is very important that, for the Court Meeting in particular, as many votes as possible are cast so that the Court may be satisfied that there is a fair and reasonable representation of the opinion of Scheme Shareholders. SCHEME SHAREHOLDERS ARE THEREFORE STRONGLY URGED TO COMPLETE, SIGN AND RETURN THEIR FORMS OF PROXY OR APPOINT A PROXY THROUGH THE CREST ELECTRONIC PROXY APPOINTMENT SERVICE, PROXYMITY OR BY OTHER ELECTRONIC MEANS (AS APPROPRIATE), OR, IN THE CASE OF ONTHEMARKET NOMINEE SERVICE HOLDERS, RETURN THEIR FORMS OF INSTRUCTION BY POST OR SUMBIT THEIR VOTING INSTRUCTIONS ELECTRONICALLY, AS SOON AS POSSIBLE.

Expected timetable

The Scheme Document contains an expected timetable of principal events relating to the Scheme, which is also attached as an Appendix to this announcement. Subject to obtaining the approval of OnTheMarket Shareholders and the Court and the satisfaction or, where applicable, waiver of the other Conditions (as set out the Scheme Document), the Scheme is expected to become Effective on 12 December 2023.

If any of the key dates set out in the timetable change, OnTheMarket will give notice of this change by issuing an announcement through a Regulatory Information Service and by making such announcement available on OnTheMarket's website at https://plc.onthemarket.com/recommended-cash-acquisition/.

Further information

This announcement is for information purposes only and is not intended to and does not constitute, or form any part of, an offer to sell or subscribe for or any invitation to purchase or subscribe for any securities or the solicitation of any vote or approval in any jurisdiction pursuant to the Acquisition or otherwise. The Acquisition will be implemented solely through and on the terms set out in the Scheme Document and the accompanying Forms of Proxy (or, in the event that the Acquisition is to be implemented by means of a Takeover Offer, the Offer Document and form of acceptance), which will contain the full terms and conditions of the Acquisition, including details of how to vote in respect of the Scheme, or to accept the Takeover Offer. Any approval, decision or other response to the Acquisition should be made only on the basis of the information in the Scheme Document (or if the Acquisition is implemented by way of a Takeover Offer, the Offer Document). OnTheMarket Shareholders are strongly advised to read the formal documentation in relation to the Acquisition.

This announcement does not constitute a prospectus or prospectus exempted document.

The statements contained in this announcement are made as at the date of this announcement, unless some other time is specified in relation to them, and the publication of this announcement shall not give rise to any implication that there has been no change in the facts set forth in this announcement since such date.

Overseas Shareholders

This announcement has been prepared for the purpose of complying with English law, the AIM Rules, the Code and the Market Abuse Regulation 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.

The release, publication or distribution of this announcement in jurisdictions other than the United Kingdom may be restricted by law and/or regulations and such laws and/or regulations may affect the availability of the Acquisition to persons who are not resident in the United Kingdom. Persons who are not resident in the United Kingdom, or who are subject to laws of any jurisdiction other than the United Kingdom, should inform themselves about, and observe, any applicable requirements. Any failure to comply with the applicable legal or regulatory requirements may constitute a violation of the laws and/or regulations of any such jurisdiction. To the fullest extent permitted by applicable law, the companies and persons involved in the Acquisition disclaim any responsibility and liability for the violation of such restrictions by any person.

Any person (including, without limitation, nominees, trustees and custodians) who would, or otherwise intends to, forward this announcement, the Scheme Document or any accompanying document(s) to any jurisdiction outside the United Kingdom should refrain from doing so and seek appropriate professional advice before taking any action. In particular, the ability of persons who are not resident in the United Kingdom to vote their OnTheMarket Shares at the Court Meeting or the General Meeting, or to execute and deliver Forms of Proxy appointing another to vote their OnTheMarket Shares in respect of the Court Meeting or the General Meeting on their behalf, or otherwise to provide voting instructions in respect of the Court Meeting or the General Meeting, may be affected by the laws of the relevant jurisdiction in which they are located. The Acquisition will be subject to the applicable requirements of the Code, the Takeover Panel, the London Stock Exchange (including the AIM Rules) and the FCA.

Unless otherwise determined by CoStar and/or CoStar UK or required by the Code, and permitted by applicable law and regulation, the Acquisition will not be made, directly or indirectly, in or into or by use of the mails or any other means or instrumentality (including, without limitation, telephonic or electronic) of interstate or foreign commerce of, or any facility of a national, state or other securities exchange of, a Restricted Jurisdiction, and no person may vote in favour of the Scheme, and any Takeover Offer will not be capable of acceptance, by any such use, means, instrumentality or facility or from within a Restricted Jurisdiction. Accordingly, copies of this announcement and the formal documentation relating to the Acquisition are not being, and must not be, directly or indirectly, mailed or otherwise forwarded or distributed in, into or from a Restricted Jurisdiction and persons receiving this announcement (including custodians, nominees and trustees) must not distribute or send it into or from a Restricted Jurisdiction.

In the event that the Acquisition is implemented by way of a Takeover Offer and extended into the US, CoStar UK will do so in satisfaction of the procedural and filing requirements of the US securities laws at that time, to the extent applicable thereto.

The Acquisition relates to the shares of a company incorporated in England and it is proposed to be made by means of a scheme of arrangement provided for under English law. A transaction effected by means of a scheme of arrangement is not subject to the shareholder vote, proxy solicitation and tender offer rules under the US Exchange Act. Accordingly, the Scheme is subject to the disclosure requirements and practices applicable in the UK to schemes of arrangement, which differ from the disclosure requirements and practices of US shareholder vote, proxy solicitation and tender offer rules.

If CoStar UK were to elect to implement the Acquisition by means of a Takeover Offer, such Takeover Offer shall be made in compliance with all applicable laws and regulations, including section 14(e) of the US Exchange Act and Regulation 14E thereunder. Such Takeover Offer would be made in the US by CoStar UK and no one else.

In addition to any such Takeover Offer, CoStar UK, certain affiliated companies and the nominees or brokers (acting as agents) of CoStar UK and/or such affiliated companies may make certain purchases of, or arrangements to purchase, OnTheMarket Shares outside such Takeover Offer during the period in which such Takeover Offer would remain open for acceptance. If such purchases or arrangements to purchase are made, they would be made outside the United States in compliance with applicable law, including the US Exchange Act.

The receipt of cash consideration by an OnTheMarket Shareholder for the transfer of their OnTheMarket Shares pursuant to the Scheme will be a taxable transaction for United States federal income tax purposes and under applicable US state and local, as well as overseas and other, tax laws. In certain circumstances, OnTheMarket Shareholders that are not US persons and that receive cash consideration pursuant to the Scheme may be subject to US withholding tax. Each OnTheMarket Shareholder is urged to consult an independent professional adviser regarding the applicable tax consequences of the Acquisition, including under applicable United States, state and local, as well as overseas and other tax laws.

Financial information relating to OnTheMarket included in this announcement and to be included in the Scheme Document has been, or will have been, prepared in accordance with accounting standards applicable in the United Kingdom and may not be comparable to the financial statements of US companies or companies whose financial statements are prepared in accordance with generally accepted accounting principles in the United States ("US GAAP"). US GAAP differs in certain significant respects from accounting standards applicable in the United Kingdom.

It may be difficult for a US-based investor to enforce their rights and any claim they may have arising under US securities laws since the Scheme relates to the shares of a company incorporated under the laws of, and located in, the United Kingdom, and some or all of its officers and directors may be residents of non-US jurisdictions. A US-based investor may not be able to sue a company located in the United Kingdom, or its officers or directors, in a foreign court for alleged violations of US securities laws, and it may be difficult to compel a foreign company and its affiliates to subject themselves to a US court's judgment.

Further details in relation to Overseas Shareholders are contained in the Scheme Document.

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: (a) the offeree company; and (b) any securities exchange offeror(s). An Opening Position Disclosure by a person to whom Rule 8.3(a) applies must be made by no later than 3.30 pm on the 10th Business Day (as defined in the Code) following the commencement of the Offer Period and, if appropriate, by no later than 3.30 pm on the 10th Business Day (as defined in the Code) 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: (a) the offeree company; and (b) any securities exchange offeror, 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 on the Business Day (as defined in the Code) 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 Takeover 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. You should contact the Takeover Panel's Market Surveillance Unit on +44 (0) 20 7638 0129 if you are in any doubt as to whether you are required to make an Opening Position Disclosure or a Dealing Disclosure.

General

CoStar UK reserves the right to elect, with the consent of the Panel (where necessary), to implement the Acquisition by way of a Takeover Offer for the entire issued and to be issued share capital of OnTheMarket not already held by CoStar UK as an alternative to the Scheme. In such an event, a Takeover Offer will be implemented on substantially the same terms, so far as applicable, as those which would apply to the Scheme.

If the Acquisition is effected by way of Takeover Offer, and such Takeover Offer becomes or is declared unconditional in all respects and sufficient acceptances are received, CoStar UK intends to exercise its rights to apply the provisions of Chapter 3 of Part 28 of the Companies Act so as to acquire compulsorily the remaining OnTheMarket Shares in respect of which the Takeover Offer has not been accepted.

If you are in any doubt about the contents of this announcement or the action you should take, you are recommended to seek your own independent financial advice immediately from your stockbroker, bank manager, solicitor or independent financial adviser duly authorised under the Financial Services and Markets Act 2000 (as amended) if you are resident in the United Kingdom or, if not, from another appropriately authorised independent financial adviser.
