To the Shareholders of DCC plc

Dear Shareholder

The Notice of the Fiftieth Annual General Meeting of DCC plc to be held on Thursday, 16 July 2026 at 2.00 p.m. is set out on pages 4 to 8 of this document.

I invite you to submit questions in writing in advance of the meeting either by email to [email protected] or by post to the Company Secretary, DCC plc, DCC House, Leopardstown Road, Foxrock, Dublin 18, Ireland. Questions must be received by 2.00 p.m. on Tuesday, 14 July 2026. All correspondence should include sufficient information to identify the shareholder on the Register of Members.

The resolutions to be proposed at the Annual General Meeting are set out in detail in the Notice and explanatory notes on the resolutions are set out below.

Resolution 1 – Financial Statements

Resolution 1 deals with the consideration of the financial statements of the Company for the year ended 31 March 2026. A full copy of the 2026 Annual Report and Accounts is available on the Company's website www.dcc.ie.

Resolution 2 – Dividend

Resolution 2 deals with the declaration of a final dividend of 147.22 pence per ordinary share for the year ended 31 March 2026. If approved, the final dividend will be paid on 23 July 2026 to shareholders on the Register of Members at the close of business on 29 May 2026. This will give a total dividend for the year of 216.72 pence per ordinary share, which represents a 5.0% increase on the prior year.

Resolutions 3 and 4 – Remuneration Report and Remuneration Policy

Resolution 3 deals with the consideration of the Remuneration Report (excluding the Remuneration Policy referred to in Resolution 4) as set out on pages 100 to 124 of the 2026 Annual Report and Accounts.

Resolution 4 deals with the consideration of a limited number of amendments to the Remuneration Policy. Those amendments are set out and explained in detail in the Remuneration Report; the Remuneration Policy is set out on pages 106 to 113 of the 2026 Annual Report and Accounts. Consistent with DCC's approach to transparent engagement, the Remuneration Committee consulted major institutional shareholders ahead of finalising the proposed changes to the Remuneration Policy. Institutional shareholders representing over 60% of the Company's share capital were invited to provide feedback on proposed policy changes and this feedback was reflected in the changes now being proposed. Further detail on this process is contained on page 102 of the 2026 Annual Report and Accounts.

It is the Company's practice to put the Remuneration Report to an advisory, non-binding shareholder vote at each Annual General Meeting. It is also the Company's practice to put the Remuneration Policy to an advisory, non-binding shareholder vote every three years or earlier if there are changes to the Policy. At this Annual General Meeting, both the Remuneration Report and the Remuneration Policy will be put to advisory, non-binding shareholder votes.

Resolution 5 – Election and re-election of Directors

Resolution 5 deals with the proposed election or re-election of all Directors who are putting themselves forward at the Annual General Meeting, in accordance with the UK Corporate Governance Code.

The Board undertakes a formal annual evaluation of its Directors and is satisfied that all the Directors proposed for election or re-election continue to make a valuable contribution and have performed effectively in offering independent and constructive challenge to management and committed sufficient time to discharge their responsibilities effectively.

Brief biographies of the Directors, including their areas of expertise relevant to their role as Directors, are set out on pages 82 and 83 of the 2026 Annual Report and Accounts and also on the Company's website www.dcc.ie.

The election or re-election of each Director will be considered separately.

Resolution 6 – Remuneration of the Auditors

Resolution 6 authorises the Directors to determine the remuneration of the Auditors.

Directors: Mark Breuer (Chair, British), Donal Murphy (Chief Executive), Laura Angelini (US & Italian), Katrina Cliffe (British), Caroline Dowling, Lily Liu (British & Australian), Steven Holland (British) Kevin Lucey (Executive), Conor Murphy (Executive), Alan Ralph, Mark Ryan. Registered Office: DCC House, Leopardstown Road, Foxrock, Dublin 18. Registered in Ireland Number: S4858

Resolution 7 – Authority to allot shares

Resolution 7 will be proposed as an Ordinary Resolution to authorise the Directors to allot shares up to an aggregate nominal amount of €7,118,600, representing approximately one third of the Company's issued share capital (excluding Treasury Shares) on 10 June 2026. As at close of business on 10 June 2026, the Company held 2,185,094 Treasury Shares, representing 2.56% of the Company's issued share capital (excluding Treasury Shares). The Directors have no present intention of making any new issue of shares (other than pursuant to the DCC plc Long Term Incentive Plan 2009, the DCC plc Long Term Incentive Plan 2021, or the deferred bonus arrangements for executive Directors) and will exercise this authority only if they consider it to be in the best interests of shareholders generally at that time. This authority will, if renewed, expire on the earlier of the date of the next Annual General Meeting of the Company and 15 October 2027.

Resolutions 8 and 9 – Disapplication of pre-emption rights

Resolution 8 will be proposed as a Special Resolution to renew the Directors' authority to issue shares for cash other than strictly pro-rata to existing shareholdings. The proposed authority is limited to the allotment of shares in specific circumstances relating to rights issues or any other issues up to an aggregate nominal amount of €1,067,800, representing approximately 5% of the Company's issued share capital (excluding Treasury Shares) on 10 June 2026.

Resolution 9 will be proposed as a Special Resolution to authorise the Directors to issue additional shares for cash other than strictly pro-rata to existing shareholdings. The proposed authority:

• is limited to the allotment of shares for cash up to an aggregate nominal value of €1,067,800, which represents approximately 5% of the Company's issued share capital (excluding Treasury Shares) on 10 June 2026; and
• will only be used in connection with an acquisition or other capital investment which is announced contemporaneously with the allotment, or has taken place in the preceding six-month period and is disclosed in the announcement of the allotment.

The maximum nominal value of equity securities which could be allotted if both authorities proposed by Resolutions 8 and 9 were used in full would be €2,135,600, which represents approximately 10% of the Company's issued share capital (excluding Treasury Shares) on 10 June 2026. This limit includes any Treasury Shares re-issued by the Company while these authorities remain operable.

In November 2022, the Pre-Emption Group published a revised Statement of Principles (the "Statement of Principles"), which increased the guideline aggregate threshold for the annual disapplication of pre-emption rights authorities from 10% to 20% of a company's issued share capital, with some additional flexibility for follow-on offers of up to a maximum of an additional 4% of a company's issued share capital in specified circumstances. However, the Directors have decided to seek authority under Resolutions 8 and 9 for the disapplication of pre-emption rights only up to a maximum of 10% of the Company's issued share capital in the aggregate. Resolution 9 reflects the Statement of Principles and related templates, and is in line with the authorities received by the Company in prior years. If the Company issues shares non-pre-emptively for cash, it will follow the shareholder protections in Part 2B of the Statement of Principles.

The Directors will exercise these authorities only if they consider them to be in the best interests of shareholders generally at that time. These authorities will, if renewed, expire on the earlier of the date of the next Annual General Meeting of the Company and 15 October 2027.

Resolution 10 – Authority to purchase own shares

Resolution 10 will be proposed as a Special Resolution to renew the authority of the Company, or any subsidiary, to purchase on-market from time to time shares representing up to 10% of the aggregate nominal value of the Company's issued share capital (excluding Treasury Shares) and to hold these shares as Treasury Shares or cancel them at the Directors' discretion. The resolution also sets out the minimum and maximum prices that may be paid for shares purchased in this manner.

If the Directors were to exercise the authority being renewed by this resolution up to the maximum number of shares allowed, the total number of options to subscribe for ordinary shares in the Company (which, on 10 June 2026, was 765,666, representing 0.9% of the issued share capital (excluding Treasury Shares)) would represent 1% of the issued share capital (excluding Treasury Shares).

This authority will, if renewed, expire on the earlier of the date of the next Annual General Meeting of the Company and 15 January 2028.

Resolution 11 – Re-issue price of Treasury Shares

Resolution 11 will be proposed as a Special Resolution to set the price range at which any Treasury Shares may be re-issued off-market. This authority will, if renewed, expire on the earlier of the date of the next Annual General Meeting of the Company and 15 January 2028.

Resolution 12 – Amendment to the Rules of the DCC plc Long Term Incentive Plan 2021 (the “2021 Plan”)

Resolution 12 will be proposed as an Ordinary Resolution and so as to give effect to Resolution 4. As explained on pages 101 and 102 of the 2026 Annual Report and Accounts, following the Remuneration Committee's review of the effectiveness of DCC's current long-term incentive arrangements in the context of DCC's strategic evolution, the Remuneration Committee is proposing to amend the Remuneration Policy so as to introduce an absolute total shareholder return kicker (the "TSR Kicker") as a targeted enhancement to DCC's existing long term incentive framework.

So that awards can be granted under the 2021 Plan which incorporate the TSR Kicker in accordance with the Remuneration Policy (and not for any other purpose), it is proposed to amend the rules of the 2021 Plan to provide that participants under the 2021 Plan may be granted awards in any accounting period over shares in DCC with a market value of up to 500% of the annual rate of basic salary of the participant.

A copy of the proposed revised rules of the 2021 LTIP Plan will be available for inspection via the National Storage Mechanism and on the Company's website www.dcc.ie from the date of this document and at the place of the Annual General Meeting for at least 15 minutes before the Annual General Meeting and during the Annual General Meeting. Resolution 12 is conditional on the passing of Resolution 4.

Resolution 13 – Change of Company name

Resolution 13 will be proposed as a Special Resolution to authorise the Company to change its name to DCC Energy plc and amend the Memorandum and Articles of Association of the Company to reflect such change.

As part of the Company's announcement on 19 May 2026 of its preliminary statement of results for the year ended 31 March 2026, the Company announced its proposal, subject to shareholder approval, to change its name from DCC plc to DCC Energy plc. A letter setting out the background to, and details of, the proposed change of name, was sent to the Company's major institutional shareholders in March 2026. Responses received from shareholders to the proposed change were very positive.

1. To propose and consider and, if thought fit, to approve the following as a Special Resolution:

"That for the purposes of Section 1078 of the Companies Act 2014, the re-issue price range at which ordinary shares of €0.25 in the capital of the Company ("Shares") held as Treasury Shares (as defined by Section 106 of that Act) may be re-issued off-market shall be as follows:

b) the minimum price at which a Treasury Share may be re-issued off-market shall be an amount equal to 95% of the Appropriate Price, provided that if Treasury Shares (including Treasury Shares held by the Company at the date of passing of this Resolution) are being re-issued for the purposes of the DCC plc Long Term Incentive Plan 2009 or the DCC plc Long Term Incentive Plan 2021, the re-issue price shall be the issue or subscription price provided for in such Plan (as applicable).

For the purposes of this resolution the expression "Appropriate Price" shall mean an amount equal to the average of the five amounts resulting from determining whichever of the following (i., ii. or iii. specified below) in relation to the Shares of the same class as the Treasury Share being re-issued shall be appropriate for each of the five business days immediately preceding the day on which the Treasury Share is re-issued as determined from the information published in the Daily Official List of the London Stock Exchange reporting the business done on each of those five business days:

i. if there shall be more than one dealing reported for the day, the average of the prices at which such dealings took place; or
ii. if there shall be only one dealing reported for the day, the price at which such dealing took place; or
iii. if there shall not be any dealing reported for the day, the average of the high and low market guide prices for that day, and if there shall be only a high (but not a low) or a low (but not a high) market guide price reported, or if there shall not be any market guide price reported for any particular day, then that day shall not count as one of the said five business days for the purposes of determining the Appropriate Price.

If the means of providing the foregoing information as to dealings and prices by reference to which the Appropriate Price is to be determined is altered or is replaced by some other means, then the Appropriate Price shall be determined on the basis of the equivalent information published by the relevant authority in relation to dealings on the London Stock Exchange or its equivalent.

This resolution shall continue in effect until the close of business on the earlier of the date of the next Annual General Meeting of the Company or 15 January 2028 unless previously varied or renewed in accordance with the provisions of Section 1078 of the Companies Act 2014."

Euroclear UK & International Limited ("EUI"), the operator of CREST has arranged for holders of CDIs to issue voting instructions relating to ordinary shares via a third-party service provider, Broadridge Financial Solutions Limited ("Broadridge"). CDI holders can complete and submit electronic voting instructions or proxy appointment instructions electronically through Broadridge.

If you hold CDIs and wish to submit electronic voting instructions or proxy appointment instructions you must use the Broadridge Global Proxy Voting service. To avail of the voting service, you will need to complete the Meetings and Voting Client Set-up Form (CRT408) prescribed by Broadridge. Completed application forms should be returned to EUI (signed by an authorised signatory with another relevant authorised signatory copied for verification purposes) to the following email address: [email protected]. Fully completed application forms will be shared by EUI with Broadridge. This will enable Broadridge to contact you and share further detailed information on the service offering and initiate the process for granting you access to the Broadridge platform.

Broadridge will set a voting deadline by which time electronic voting instructions or proxy appointment instructions must be received by it for use at the Annual General Meeting. Broadridge's voting deadline will be earlier than Euroclear Bank's voting instruction deadline. Voting instructions cannot be changed or cancelled after Broadridge's voting deadline.

CDI holders are strongly encouraged to familiarise themselves with the arrangements with Broadridge, including the voting deadlines and procedures and to take, as soon as possible, any further actions required by Broadridge in order that they may avail of this voting service.

1. All proxy appointments and voting instructions (whether submitted directly or through the EB System or (via a holding of CDIs) CREST) must be received by the Company's Registrar not less than 48 hours before the time appointed for the Annual General Meeting or any adjournment thereof. However, persons holding through the EB System or (via a holding of CDIs) CREST will also need to comply with any earlier voting deadlines imposed by their respective custodian, stockbroker or other intermediary. All persons affected are recommended to consult with their custodian, stockbroker or other intermediary at the earliest opportunity and, following submission of voting instructions/proxy appointments, to confirm with such relevant intermediary that the votes/appointments have been validly received and processed.

2. Voting on each of the resolutions will be decided on a poll. Pursuant to Section 190(b) of the Companies Act 2014, where a poll is taken at the Annual General Meeting, a shareholder, present in person or by proxy, holding more than one share need not cast all his/her votes in the same way.

3. Resolutions 3 and 4 are advisory resolutions and are not binding on the Company.

4. The Company, pursuant to Section 1087G of the Companies Act 2014, specifies that only those shareholders registered in the Register of Members of the Company as at the close of business (deemed to be 6.00 p.m. (Irish Time)) on Sunday, 12 July 2026 (or if the Annual General Meeting is adjourned for 14 days or more, at 6.00 p.m. on the day immediately preceding the date that falls 72 hours before the time appointed for the adjourned meeting) shall be entitled to attend, speak, ask questions and vote at the Annual General Meeting in respect of the number of shares registered in their names at the time. Changes to entries in the Register of Members after that time will be disregarded in determining the right of any person to attend and/or vote at the meeting.

5. A copy of this Notice, details of the total number of shares and voting rights at the date of this Notice and copies of documentation relating to the 2026 Annual General Meeting can be obtained from the Company's website, www.dcc.ie.
