Introduction

By resolution of 12 April 2022, the Ordinary Shareholders' Meeting approved a share allocation plan reserved for employees of Prysmian S.p.A. (the "Company") and Prysmian Group companies (the "2022-2024 Plan"), described in the information document prepared pursuant to art. 84-bis of the regulation adopted by Consob with resolution no. 11971 of 14 May 1999, as subsequently amended, available on the Company's website www.prysmian.com (in the Company/Governance/Remuneration section).

The 2022-2024 Plan provides for the free allocation of ordinary shares of the Company to the shareholders. These shares are expected to derive from a capital increase to be carried out through the use, pursuant to Article 2349 of the Italian Civil Code, of profits or reserves from profits and, if necessary, on the basis of the regulations of the plan itself, from treasury shares of the Company.

In order to ensure sufficient supply of shares to service the 2022-2024 Plan, on the proposal of the Board, the aforementioned Shareholders' Meeting, in extraordinary session, had resolved to increase the share capital free of charge for a maximum nominal amount of Euro 300,000.00, through the assignment pursuant to art. 2349 of the Italian Civil Code of a corresponding maximum amount taken from the "Reserve for the issue of shares pursuant to Article 2349 of the Italian Civil Code", with the issue of no more than 3,000,000 ordinary shares (the "2022 Resolution") to be reserved for participants in the 2022-2024 Plan.

Finally, the Extraordinary Shareholders' Meeting had amended Article 6 of the Articles of Association to implement the resolution to increase share capital, adding the following paragraph:

"The Extraordinary Shareholders' Meeting dated 12 April 2022 resolved to increase the share capital for a maximum amount of Euro 300,000.00, through the allotment under art. 2349 of the Italian Civil Code, of an equivalent amount deriving from the "Reserve for shares issue ad per article 2349 of the Italian Civil Code", with the issue of up to no. 3,000,000 ordinary shares with a nominal value of €0.10 each, to be offered free of charge to the employees of Prysmian S.p.A. and Prysmian Group's companies, beneficiaries of the stock grant plan approved by the Ordinary Shareholders' Meeting of 12 April 2022, and to be carried out by the final date of 31 December 2026".

In view of the above, the Board of Directors proposes to reduce the aforementioned share capital increase to service the 2022-2024 Plan from the current maximum nominal amount of Euro 300,000.00, corresponding to 3,000,000 new ordinary shares, executed for Euro 157,957.90 with the issue of 1,579,579 ordinary shares, with a maximum nominal value of Euro 25,000.00, corresponding to no. 250,000 new ordinary shares, by revoking the 2022 Resolution and adopting a new shareholders' resolution with the consequent adaptation of Article 6 of the Articles of Association.

1. Reasons and destination of the Capital Increase

The proposal to revoke 2022 Resolution stems from analyses recently conducted regarding the actual number of shares required for the 2022-2024 Plan in its final year of implementation. Taking into account the allocations already made in previous years, it was concluded that the remaining number of shares envisaged by 2022 Resolution exceeds what is actually needed.

Therefore, in order to reduce the maximum number of shares that can be allocated free of

charge to the participants of the 2022-2024 Plan in its final year of implementation, the Board proposes a corresponding reduction of the capital increase to service this plan from the current maximum nominal amount of Euro 300,000.00, corresponding to 3,000,000 new ordinary shares, to a maximum nominal amount of Euro 25,000.00, corresponding to no. 250,000 new ordinary shares (the "2026 Resolution").

The purposes of the 2022-2024 Plan, which would remain unchanged and to which reference is made, are considered to justify the remaining, also with reference to the 2026 Resolution, of the exclusion of pre-emption rights in favour of shareholders.

The capital increase referred to in the 2026 Resolution, which replaces the revoked 2022 Resolution, is at the exclusive service of the aforementioned 2022-2024 Plan and is therefore intended for employees of Prysmian S.p.A. and of Italian and foreign companies of the Prysmian Group, pursuant to art. 2349 of the Civil Code.

The shares may also be issued in several tranches over the duration of the capital increase resolution, and in any case by the deadline of 31 December 2026.

2. Features of the Shares

The Company's shares that may be assigned to the beneficiaries of the 2022-2024 Plan will have dividend rights equal to that of the Company's ordinary shares currently outstanding and will therefore have coupons in effect on that date. However, there may be restrictions on the availability of the shares applicable to the participants in the Plan.

3. Amendment to the Articles of Association as a result of the resolution proposing the capital increase

The revocation of the 2022 Resolution and the approval of the new 2026 Resolution entail the need to adapt Article 6 of the Articles of Association accordingly.

In particular, the current second paragraph of Article 6 of the Articles of Association will be amended as indicated below in the comparative comparison of the current text with the amended one to take into account the proposal described above.

Finally, it should be noted that some paragraphs of art. 6 of the Articles of Association are subject to further amendments by the Extraordinary Shareholders' Meeting in the context of other items on the agenda.
