SUBJECT: EXPLANATORY REPORT ON THE REASONS FOR THE PROPOSED RESOLUTION SUBMITTED BY GRUPPO IPG HOLDING S.P.A. WITH REGARD TO THE SIXTH ITEM ALREADY ON THE AGENDA OF THE ORDINARY PART OF THE SHAREHOLDERS' MEETING OF INTERPUMP GROUP S.P.A. OF 30 APRIL 2026

Shareholders,

This report has been prepared by Gruppo IPG Holding S.p.A., with registered office at Via Pontaccio 10, Milan, tax code 05830220967, in its capacity as a shareholder of INTERPUMP GROUP S.p.A. ("Company" and/or "Issuer"), in order to explain the reasons for the proposed resolution ("Proposal") submitted by Gruppo IPG Holding S.p.A. pursuant to Article 126-bis of Legislative Decree No. 58/1998 ("TUF") on the sixth item ("Appointment of the Board of Directors: appointment of the members of the Board of Directors") already on the agenda of the ordinary part of the Company's Shareholders' Meeting convened for 30 April 2026 at 10:00 a.m., in a single call, which, as usual, shall be deemed to be held at the offices of Interpump Group S.p.A. located in Reggio Emilia, Via G.B. Vico 2 ("Meeting").

As stated in the Proposal, today, the undersigned shareholder submitted a list of candidates for the appointment to the Company's Board of Directors ("List"), and one of the candidates named on the List, Ms Elena Iotti, currently holds the position of Independent Director at Emak S.p.A., a company at the head of a group operating in the field of designing solutions for gardening, forestry, agriculture, cleaning and industry, whose activities are in part similar to those carried out by Interpump Group S.p.A. within its business segment relating to high-pressure pumps for the cleaning and industrial markets. Therefore, in view of certain areas of partial overlap, it is deemed appropriate to submit the following proposed resolution to the Shareholders' Meeting for its consideration, pursuant to and for the purposes of Article 2390 of the Civil Code:

• having noted the election of Ms Elena Iotti as Independent Director of the Company further to the vote on the List for the appointment of the Board of Directors submitted by the shareholder Gruppo IPG Holding S.p.A., as well as Ms Iotti acceptance of said office;
• having taken into account that Ms Elena Iotti also holds the office of Independent Director at Emak S.p.A.;
• having examined the proposed resolution on the sixth item on the agenda of the ordinary part of today's Shareholders' Meeting and the related explanatory report submitted by the shareholder Gruppo IPG Holding S.p.A. pursuant to Article 126-bis of the TUF,

resolves

• to authorise, pursuant to Article 2390 of the Civil Code, Ms Elena Iotti to retain her position as Independent Director of Emak S.p.A. and to continue performing the related duties for the entire duration of Ms Elena Iotti term of office at Interpump Group S.p.A."

It should be noted that the above proposal for a resolution is conditional on Ms Elena Iotti being appointed as a Director of the Company following the vote on the list submitted by Gruppo IPG Holding S.p.A. Therefore, the appointment of the candidate remains subject to the provisions of the Articles of Association and the law applicable to the composition of the Board of Directors.

For the purposes of this proposed resolution, the main reasons are set out below.

Based on the information publicly available at the date of this report, the potentially overlapping activities appear to be of limited significance in relation to the Interpump Group's overall business volume, accounting for less than 5% of revenues.

It should also be noted that the position of Independent Director held by Ms Elena Iotti at Emak S.p.A. is, by its very nature, characterised by the complete absence of operational delegated powers and management authority. Should she be elected, Ms Elena Iotti would also hold the same office at Interpump Group S.p.A., thereby mitigating any risks associated with the situations referred to in Article 2390(1) of the Civil Code.

There are no situations, either currently or in the foreseeable future, involving the overlap of managerial or operational roles in the two companies that would result in Ms Iotti active involvement in significant competitive dynamics between the two companies.

Furthermore, the undersigned shareholder believes that the addition to the Company's Board of Directors of a professional with in-depth knowledge of the relevant markets, as well as of the shared sectoral dynamics, could enrich the Board's discussions and enhance its wealth of expertise.

In light of the above considerations, the situation described does not appear likely to prejudice the Company's interests or to compromise the independence of judgement required of Independent Directors, it being understood that any assessment as to whether the independence requirements are met and continue to be met is the responsibility of the Company's Board of Directors. Therefore, with a view to ensuring complete fairness and transparency of information vis-à-vis the Shareholders, who by law are empowered to
