Rexel announces the success of its c. €500 million Capital Increase, without shareholders’ preferential subscription right, to partially fund the acquisition of GCG

• Rexel announces today the success of its share capital increase of approximately 500 million euros by means of an issue of new shares without shareholders’ preferential subscription right via an accelerated bookbuilding
• The net proceeds from the capital increase will be used to partially finance the acquisition of GCG, as previously announced in the company’s press release dated 25 September 2026

Paris, September 29, 2026

Rexel (the “Company”) has successfully placed 14,388,490 new shares (the “New Shares”, representing c. 4.6% of the share capital of the Company prior to the issue) in an offering by way of an accelerated bookbuilding. The New Shares will be issued in a capital increase without shareholders’ preferential subscription rights (the “Capital Increase”) at a price of EUR 34.75 per share resulting in gross proceeds of approximately 500 million euros before deduction of commissions and expenses.

The subscription price is set at €34.75 per New Share (including €5.00 of par value and €29.75 of issue premium), representing a discount of c. 1.0% on the last closing price prior to the announcement of the launch of the Capital Increase on 28 September 2026.

Use of proceeds

The net proceeds from the Capital Increase will be used to partially finance the acquisition of GCG (the “Acquisition”) and will contribute to preserving Rexel’s credit rating and maintaining a net financial debt / EBITDAaL ratio of approximately 2.0x from 2027, in line with its guidance, thereby strengthening its financial flexibility and capacity to capture the multiple growth opportunities ahead.

The Capital Increase represents the equity component of the Acquisition’s financing structure which would also encompass a mix of cash on hand and debt. For further details on the Acquisition and its funding, please see the Company’s announcement of September 25, 2026.

Key terms and indicative timetable of the Capital Increase

The Capital Increase has been carried out without shareholders’ preferential subscription right nor priority subscription period pursuant to the authorization granted by the Company’s annual shareholders’ general meeting held on 29 April 2025 (18th resolution) and in accordance with the provisions of Article L.411-2 1° of the French Code monétaire et financier, in France and outside France with no public offering in any jurisdiction (including France) other than to qualified investors (as defined in Regulation (EU) 2017/1129, as amended (the “Prospectus Regulation”)).

The New Shares have been offered for subscription in a private placement by way of an accelerated bookbuilding process exclusively to qualified investors as defined in the Prospectus Regulation.

The New Shares will bear current dividend rights and will be immediately assimilated with the Company’s existing shares. The New Shares will trade under the same ISIN code as the Company’s existing shares, FR0010451203, on the regulated market of Euronext in Paris.

Settlement and delivery of the Capital Increase is expected to take place on or around October 1, 2026.

Lock-up undertaking

In the context of the Capital Increase, the Company has agreed to a lock-up undertaking with respect to the issuance or sale of shares and securities giving access to the share capital for a period ending 90 calendar days after the settlement, subject to certain customary exceptions and waiver by the Joint Global Coordinators.

Dilution

For illustrative purposes only, a shareholder holding 1% of the Company’s share capital(1) as of September 28, 2026, and not subscribing to the Capital Increase, would hold c. 0.96%, on a non-diluted basis (c. 0.93%, on a diluted basis), of the Company’s share capital(1) following the issue of the New Shares.
