To the Shareholders, Kingspan Group plc

Notice of Annual General Meeting ("AGM")

Dear Shareholder,

I enclose for your attention Notice of the Annual General Meeting of Kingspan Group plc, and invite you to join me on Friday 3 May 2019 at The Herbert Park Hotel, Ballsbridge, Dublin 4 at 10:00 a.m.

The resolutions to be proposed at the forthcoming AGM are set out on pages 3-7 of this Notice, with further explanatory notes set out on pages 8-11.

Kingspan had another record year in 2018, with trading profits of €445m, up 18% on prior year. For further details, I would encourage all Shareholders to read the Company's Business & Strategic Review for 2018 and the financial statements and directors' report which are contained in the Annual Report, all of which are available on www.kingspan.com. Accordingly the Board is pleased to recommend a final dividend of 30 cent per share which, if approved at the Annual General Meeting, will give a total dividend for the year of 42 cent.

At this year's AGM, all of your Board will retire and offer themselves for re-election by the Shareholders. A brief biography of each of the directors is set out in the notes to the resolutions. The performance of the Board is reviewed annually, and each of the directors has made a substantial contribution to the leadership and governance of the Company during the year.

This year, in line with Kingspan's commitment to best corporate governance practices and shareholder engagement, the Board has decided that shareholders should be given an advisory vote on the Kingspan directors' remuneration policy, as well as once again putting the report of the Remuneration Committee to an advisory vote at the Annual General Meeting. This will be the first time that Kingspan has presented its directors' remuneration policy to shareholders for approval.

The other items of special business at the AGM (Resolutions 8 to 13) relate to the share capital of the Company and the renewal of authorities previously given for a further 12 month period, and renewal of authority to convene certain general meetings on 14 clear days' notice. These are matters which are now standard for most public companies.

Your participation at the AGM is important for the Company, and I would encourage every Shareholder to take part in the meeting, either by attending the AGM or (if you are not able to attend) by casting your vote by proxy. Details of how you can vote, either in person or by proxy, are set out in the general notes to this circular. You can also submit a question in advance of the AGM, by sending an e-mail to agm@kingspan.com.

Your Board believes that the resolutions to be proposed at the AGM are in the best interests of the Company and its Shareholders. Accordingly the directors unanimously recommend that Shareholders vote in favour of the resolutions, as they intend to do in respect of their own beneficial holdings of shares in the Company.

Yours sincerely,

Eugene Murtagh Chairman

Resolution 4: Auditors' remuneration

The directors are seeking to renew their authority to fix the remuneration of the auditors for the year ending 31 December 2019.

Resolution 5: Non-executive directors' fees

The Articles of Association require the Company to establish, with shareholder approval, a maximum annual limit on the ordinary remuneration (i.e. directors' fees, not including executive remuneration) payable to the non-executive directors.

The Company attaches particular importance to the knowledge and breadth of experience that non-executive directors bring to the Board, and so the directors propose to seek, at the forthcoming Annual General Meeting, shareholder approval to set the ceiling on the non-executive directors' ordinary remuneration at €800,000. The previous limit (€700,000) was set in 2013, and since then number of non-executive directors on the Board has increased as has their level of responsibilities and time commitments.

Resolution 6: Directors' Remuneration Policy

Kingspan's Policy on Directors' Remuneration is contained in the Annual Report which is available on www.kingspan.com. The Board has decided, as part of its commitment to good governance and shareholder engagement, that the Kingspan directors' remuneration policy should be considered at its 2019 Annual General Meeting. The remuneration policy will provide the framework for remuneration decisions made by the Remuneration Committee from the date of the 2019 Annual General Meeting. It is intended that the policy will apply until the 2022 Annual General Meeting unless a new policy is put to shareholders by way of an advisory vote at an earlier date. This is an advisory resolution only and is not binding on the Company.

Resolution 7: Report of the Remuneration Committee

The Report of the Remuneration Committee is contained in the Annual Report which is available on www.kingspan.com. This is an advisory resolution, and is not binding on the Company and is being put to shareholders in accordance with the Company's commitment to best corporate governance practice.

Resolution 8: Allotment of shares

Shareholders are being asked to renew, until the Annual General Meeting in 2020, the usual annual authority of the directors to allot shares in the Company up to an aggregate amount equal to approximately 33.33% of the issued ordinary share capital of the Company (excluding treasury shares) as at 22 February 2019 (being the latest practicable date prior to publishing this notice). The Company holds 1,784,219 ordinary shares in treasury representing 0.99% of the total ordinary shares in issue (excluding treasury shares). The directors will exercise this authority only if they consider this to be in the best interests of shareholders generally at that time. The directors currently have no intention to allot such shares at the present time.

Resolution 9: Disapplication of pre-emption rights in respect of up to 5% of the Company's issued share capital

Shareholders are being asked to renew, until the Annual General Meeting in 2020, the power of the directors to dis-apply the statutory pre-emption provisions applying to issues of ordinary shares for cash in the event of a rights issue and for any other issue for cash up to an aggregate of 5% of the nominal value of the Company's issued ordinary share capital. The directors currently have no intention to allot such shares at the present time and will exercise this power only if they consider this to be in the best interests of shareholders generally at that time.

Resolution 10: Disapplication of pre-emption rights in respect of an additional 5% of the Company's issued share capital

In addition, shareholders are being asked to renew, until the Annual General Meeting in 2020, the directors' authority, in certain limited circumstances, to allot equity securities for cash without first being required to offer such shares to the existing shareholders in accordance with statutory preemption provisions.

The disapplication of pre-emption rights in respect of a further 5% of the Company's issued share capital in addition to the power proposed to be granted pursuant to Resolution 9 reflects the guidance from the UK Pre-Emption Group's revised Statement of Principles published on 12 March 2015 (the Statement of Principles) and the Guidance issued by the Pre-Emption Group on 5 May 2016. Apart from in connection with rights issues and other pre-emptive offers, the power will be limited to the allotment of equity securities for cash up to an aggregate of 5% of the nominal value of the Company's issued ordinary share capital provided that the power can only be used in connection with the financing or refinancing of an acquisition or specified capital investment (within the meaning of the Statement of Principles). Any such refinancing must be within six months of the original transaction. The directors will have due regard to the Statement of Principles in relation to any exercise of this power and will exercise this power only if they consider this to be in the best interests of shareholders generally at that time. The directors have no current intention to exercise this power.

Resolution 11: Purchase of own shares

Shareholders are being asked to provide, until the Annual General Meeting in 2020, an authority for the Company, or any of its subsidiaries, to purchase up to 10% of the Company's own shares. The directors would only exercise the power to purchase the Company's own shares at price levels which they considered to be in the best interests of shareholders generally, after taking account of the Company's overall financial position. The directors currently have no intention to exercise the Company's authority to purchase its own shares at the present time. The minimum price which may be paid for a purchase of the Company's own shares will be the nominal value of the ordinary shares, and the maximum price which may be paid shall be 105% of the then average market price of the ordinary shares.

There were outstanding at 22 February 2019 (being the latest practicable date prior to publishing this notice), options to subscribe for 2,140,561 ordinary shares, representing approximately 1.19% of the Company's issued share capital at that date. If the repurchase authority were to be exercised in full, the shares subject to these options would represent approximately 1.32% of the Company's issued share capital.

Resolution 12: Treasury shares

Shareholders' approval is also being sought, where the Company's shares have been repurchased (such shares being known as Treasury Shares), for re-allotment of these shares off-market at a maximum price of 120% of the then average market price of the ordinary shares, and a minimum price (other than when re-allotted under an employees' share scheme) of 95% of that average. The directors have no current intention to re-allot such shares at the present time.

Resolution 13: General meetings

Shareholders are being asked to renew, until the Annual General Meeting in 2020, the Company's authority to call a general meeting on 14 days' notice other than an annual general meeting or a meeting to consider any special resolution (being a resolution requiring a 75% majority vote). The Company confirms that it would only use the shorter notice period where it is merited by the purpose of the meeting, and directors consider that it is in the interests of the Company to retain this flexibility.

A member acting as an intermediary on behalf of one or more clients may grant a proxy to each of its clients or their nominees provided each proxy is appointed to exercise rights attached to different shares held by that member. A proxy need not be a member of the Company.
• 1. A Form of Proxy for use by members is enclosed with this Notice of Annual General Meeting (or is otherwise being delivered to shareholders). Completion of a Form of Proxy (or submission of proxy instructions electronically) will not prevent a shareholder from attending the Annual General Meeting and voting in person should he or she wish to do so.
• 1. To be valid, the Form of Proxy must be delivered to Computershare Investor Services (Ireland) Limited, PO Box 954, Sandyford, Dublin 18, Ireland (if delivered by post) or at 3100 Lake Drive, Citywest Business Campus, Dublin 24, D24 AK82, Ireland (if delivered by hand) as soon as possible and, in any event, so as to be received not less than forty-eight hours before the time for the holding of the meeting, or any adjournment thereof.

• CREST members may appoint one or more proxies through the CREST electronic proxy appointment service in accordance with the procedures described in the CREST Manual. CREST Personal Members or other CREST sponsored members who have appointed a voting service provider(s) should refer to their CREST sponsor or voting service provider(s), who will be able to take the appropriate action on their behalf. Further information on CREST procedures and requirements is contained in the CREST Manual. The message appointing a proxy(ies) must be transmitted so as to be received by the Company's Registrar (CREST Participant ID 3RA50) by the latest times(s) for receipt of proxy appointments specified in this notice of meeting. For this purpose, the time of receipt will be taken to be the time (as determined by the timestamp generated by the CREST system) from which the Registrar is able to retrieve the message by enquiry to CREST in the manner prescribed by CREST. The Company may treat as invalid a proxy instruction in the circumstances set out in Regulation 35(5)(a) of the Companies Act 1990 (Uncertificated Securities) Regulations 1996.

CREST members and, where applicable, their CREST sponsors or voting service providers should note that Euroclear UK and Ireland does not make available special procedures in CREST for any particular messages. Normal system timings and limitations will therefore apply in relation to the input of CREST Proxy Instructions. It is the responsibility of the CREST member concerned to take (or, if the CREST member is a CREST Personal Member or Sponsored Member or has appointed a voting service provider(s), to procure that his CREST sponsor or voting service provider(s) take(s)) such action as shall be necessary to ensure that a message is transmitted by the CREST system by any particular time. In this connection, CREST members and, where applicable, their CREST sponsors or voting service providers are referred, in particular, to those sections of the CREST Manual concerning practical limitations of the CREST system and timings.
