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 7 May 2015 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 4-8 of this Notice, with further explanatory notes set out on pages 9-15.

I would encourage all Shareholders to read the Company's Business Review for 2014 which is contained in the Annual Report, which is available on www.kingspan.com. The financial statements and directors' report give details of what was a very positive year for Kingspan. Accordingly the Board is pleased to recommend a final dividend of 10.00 cent per share which, if approved at the Annual General Meeting, will give a total dividend for the year of 16.25 cent.

In accordance with Kingspan's commitment to best practice corporate governance, all of your Board will retire and offer themselves for re-election by the Shareholders. Two of your directors, Michael Cawley and John Cronin, were co-opted to the Board during the year and will, in accordance with the articles of association of the Company, offer themselves for election at the AGM. 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. A brief biography of each of the directors is set out in the notes to the resolutions. Also this year, as part of Kingspan's shareholder engagement, the Board is once again putting the report of the Remuneration Committee to an advisory vote.

The five items of special business at the AGM relate to the share capital of the Company and the renewal of authorities previously given for a further 12 month period. 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,

Chairman

Resolution 5: Auditors' remuneration

The directors are seeking to renew their authority to fix the remuneration of the auditors for the year ending 31 December 2015.

Resolution 6: Allotment of shares

Shareholders are being asked to renew, until the Annual General Meeting in 2016, the usual annual authority of the directors to allot the unissued share capital of the Company which is equal to 27.18% of the issued ordinary share capital of the Company as at 18 March 2015 (being the latest practicable date prior to publishing this notice). 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 7: Dis-application of pre-emption rights

In addition, shareholders are being asked to renew, until the Annual General Meeting in 2016, 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 will exercise this power only if they consider this to be in the best interests of shareholders generally at that time.

Resolution 8: Purchase of own shares

Shareholders are being asked to provide, until the Annual General Meeting in 2016, 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.

Resolution 9: 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-issue 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 of 95% of that average. The directors have no current intention to re-issue such shares at the present time.

There were outstanding at 18 March 2015 (being the latest practicable date prior to publishing this notice), options to subscribe for 4,829,300 ordinary shares, representing approximately 2.79% 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 3.10% of the Company's issued share capital.

Resolution 10: General meetings

Shareholders are being asked to renew, until the Annual General Meeting in 2016, 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 directors consider that it is in the interests of the Company to retain this flexibility.
