Mar 2, 2022

REPORT BY THE BOARD OF DIRECTORS OF PRYSMIAN S.P.A. ("PRYSMIAN" OR THE "COMPANY") TO VOTE, AS ITEM NUMBER FIVE OF THE AGENDA OF THE ORDINARY SESSION OF THE SHAREHOLDERS' MEETING SCHEDULED ON 12 APRIL 2022 (THE "SHAREHOLDERS' MEETING"), THE PROPOSAL TO AUTHORISE THE BUY-BACK AND/OR DISPOSAL OF TREASURY SHARES PURSUANT TO ARTICLE 125-TER OF THE ITALIAN LEGISLATIVE DECREE NO. 58/1998, AS AMENDED AND UPDATED, AND TO ARTICLE 73 OF THE CONSOB REGULATION ADOPTED WITH RESOLUTION NO. 11971/99, AS AMENDED AND UPDATED, DRAWN UP IN ACCORDANCE WITH FORMAT 4 OF APPENDIX 3A TO THE SAME CONSOB REGULATION.

5. Grant of authority to the Board of Directors to buy back and dispose of treasury shares pursuant to articles 2357 and 2357-ter of the Italian Civil Code; revocation of the authorization to buy back and dispose of treasury shares under the shareholder resolution dated 28 April 2021; related resolutions.

With reference to the fifth item on the agenda, the Shareholders' Meeting is asked to resolve on the proposal to authorise the purchase and disposal of treasury shares pursuant to articles 2357 and 2357-ter of the Italian Civil Code and article 132 of Italian Legislative Decree no. 58 dated 24 February 1998. The previous authorization granted by the Shareholders' Meeting held on 28 April 2021 will expired on 28 October 2022.

1. Reasons for which the authorisation is required.

The authorisation to buy back and dispose of treasury shares, including those already owned by Prysmian, is being sought to give the Company authority that can be exercised:

• to provide the Company with a portfolio of treasury shares (a stock deposit, so called "magazzino titoli"), that can be used in any extraordinary transactions (for example, merger, demerger, participation acquisition) and in order to implement the "Report on remuneration policy and compensation paid" approved by the Shareholders' Meeting and applied to the Prysmian Group;
• in order to use the treasury shares to service the exercise of rights arising from convertible debt instruments or instruments exchangeable with financial instruments issued by the Company, its subsidiaries or by third parties (for example, in frameworks of takeover bids or exchange tender offers);
• to dispose of treasury shares to satisfy share incentive or share participation plans at favourable terms reserved for Prysmian Group's directors and/or employees;
• to allow efficient management of the Company's liquidity, by creating an investment opportunity even for its available liquidity.

2. Maximum number, class and nominal value of the treasury shares to which the authorisation relates.

As of the date of this report, the subscribed, paid-in and notified to the competent Trade Register share capital of Prysmian amounts to Euro 26,814,424.60, divided into 268,144,246 ordinary shares with a nominal value of Euro 0.10 each, and the Company directly and indirectly owned 4,652,868 treasury shares, corresponding to around 1.7% of share capital with voting rights.

You are reminded that the amount of treasury shares any time held by the Company can be subject to reduction due to the followings:

• during the month of January 2021, the Company has issued a "Prysmian S.p.A. Euro 750 million Equity Linked Bonds due 2026", reserved to Institutional Investors. The bonds may be converted into newly issued shares of the Company other than, treasury shares, at the Company's discretion;
• during year 2020 Prysmian has launched a three years long-term incentive plan for Prysmian Group employees, linked to the achievement of predetermined performance conditions relating to the 2020-2022 period. Such incentive plan provides the granting of ordinary shares of the Company issued pursuant to capital increase, according to art. 2349 of the Italian Civil Code to be performed using profits or revenue reserves and, if needed according to plan rule provisions, treasury shares owned by the Company.

• since year 2016 the Company has launched a plan reserved to Prysmian Group employees at favourable terms consisting in offering the purchase of Prysmian shares with a discount, to be paid in the form of treasury shares;
• submitted to the Shareholders' Meeting for approval a three-years stock grant plan, based on financial instruments, reserved for employees of Prysmian and of companies in the Prysmian Group not involved in current individual incentive schemes, which envisages, according to the plan rules, the grant of Company's treasury shares.

Details of the abovementioned shares plans for Prysmian Group employees and of the Bonds are set out in relevant information documents, available on the Company website www.prysmiangroup.com.

The maximum number of shares that can be purchased, even in multiple solutions, will not lead the Company to hold more than 10% of the share capital at any time. Based on the current share capital, the maximum number of shares that the Company could hold is equal to no. 26,814,425, including shares already held directly or indirectly by the Company (no. 4,652,868).

In any case, under article 2357, par. 1, of the Italian Civil Code, treasury shares can be bought back on one or more occasions as long as the total does not exceed distributable profits and available reserves, as reported in the duly approved most recent annual financial statements.

3. Other information for assessing compliance with article 2357, par. 3, of the Italian Civil Code

The Board of Directors notes that the Company's financial statements for the year ended 31 December 2021, the draft of which was approved by the Board of Directors on 1 st March 2022 and will be submitted for approval by the Shareholders' Meeting, report, among others, available reserves of approximately Euro 1,986 million, or more precisely Euro 1,980 million, net of the amount of Euro 6 million to be taken from the profit reserves for the distribution of dividends, as proposed by this Board of Directors to the Shareholders' Meeting.

In relation to each purchasing of shares, every accounting entry necessary or appropriate will be executed, in relation to the transactions on treasury shares and in compliance with the current provisions of law and the applicable accounting standards.

4. Maximum term of the authorisation.

The buy-back authorisation is requested for a maximum period of 18 months from the date the Shareholders' Meeting adopts the relevant resolution.

The authorisation to dispose of treasury shares purchased under article 2357 of the Italian Civil Code is requested without any time limits.

5. Minimum and maximum price.

Treasury shares will be bought back and sold in accordance with applicable laws and regulations:

• (i) at a minimum price not less than 10% of the stock's official price recorded in the trading session on the day before the completion of each single transaction;
• (ii) at a maximum price not higher than 10% of the stock's official price recorded in the trading session on the day before the completion of single transaction.

However, these price limits might not be applied when treasury shares are used as consideration

in extraordinary transactions or to service any share-based incentive plans.

6. Ways in which treasury shares can be purchased.

In accordance with the provisions of article 132 of Italian Legislative Decree 58 dated 24 February 1998, and article 144-bis, par. 1, letters a), b), d-bis) and d-ter) of Consob Regulation 11971 dated 14 May 1999 (as amended and updated), the share buy-backs will be carried out, in such a way as to ensure equal treatment among shareholders, on regulated markets and organised by the Italian Stock Exchange according to the operating procedures established in the rules for organising and managing such markets, which do not allow the direct matching of buy orders with predetermined sell orders.

Nonetheless the purchases will be made in compliance with conditions regulated by the pro tempore applicable law, concerning the negotiation of treasury shares, and currently represented by art. 3 of Commission Delegated Regulation (EU) 2016/1052, concerning purchase price and daily volumes.

You are reminded that for the duration of the Company's ownership of the treasury shares, the voting rights of such shares are suspended along with earnings participation rights and preemption rights, all of which are proportionately assigned to the other shares.

Starting from the date of the Shareholders' resolution, we propose to revoke the current authorisation for the purchase and disposal of treasury shares, granted by the Shareholders' Meeting on 28 April 2021.
