Martin Sion to Replace Henri Poupart-Lafarge as CEO at Alstom

Alstom has announced that its Board of Directors has appointed Martin Sion as Chief Executive Officer, effective 1 April 2026.

The board made this decision following recommendations from the company’s Nominations and Remunerations Committee.

Martin Sion will succeed Henri Poupart-Lafarge, who announced in May that he would not seek a further term as CEO at Alstom, having served in the role since February 2016.

Philippe Petitcolin, Chairman of Alstom's Board of Directors, said:

The Board has conducted an extensive search process over the last few months, and we believe that Martin Sion has the necessary experience to lead Alstom. We look forward to welcoming him in April 2026. Until then, Henri Poupart-Lafarge will continue in his role, thus ensuring a smooth transition.

In the same meeting, the Board of Directors also decided on parts of Martin Sion’s remuneration:

Annual Fixed Remuneration:

• For the 2026/27 financial year: a gross annual fixed remuneration of €1,050,000, paid in 12 equal monthly instalments

Annual Variable Remuneration:

• Up to 100% of the gross annual fixed remuneration for the financial year, subject to achieving specific target performance criteria
• In the event of over-performance, this remuneration may reach up to 185% of the gross annual fixed remuneration
• The performance criteria will be set by the Board of Directors at a future date

Long-Term Variable Remuneration: 

• The CEO is eligible to participate in long-term incentive plans that Alstom may implement
• For each FY, an award with a target value of €1,200,000 will be granted, to be converted into performance shares at the time of grant
• The final number of vested shares will depend on the achievement of the relevant performance conditions and may maximally represent 150 percent of the granted shares at target without exceeding 2.5 percent of the overall amount authorised by the General Meeting for performance share awards within the Group and 10 percent of the total allocation under the plan in question

Sign-On Bonus:

• The CEO will receive a one-off sign-on bonus with a gross target value of €1,200,000 to be converted into performance shares as part of a specifically designated award for the 2026/27 financial year
• The final number of vested shares will depend on the achievement of the relevant performance conditions that will be identical to the ones set forth in the 2026/27 Long-Term variable plan and may at maximum represent 150% of the granted shares at target

• This undertaking will be effective for a period of two years from the effective end date of the CEO Mandate
• In compensation for this, the CEO will receive a gross indemnity amount to 1.5 times the average of his gross annual fixed and variable remuneration (excluding performance shares) received during the three financial years preceding the end of the mandate
• This indemnity will be paid in 24 equal monthly instalments over the duration of the non-compete clause
• Should the CEO breach this non-compete, Alstom will be released from its financial obligation and the CEO must reimburse all funds already paid in respect to the non-compete
• Alstom reserves the right to waive the non-compete, in which case no compensation shall be due and no further obligation shall apply

Severance Indemnity:

• No severance indemnity will be granted to the CEO
