YVERDON-LES-BAINS, Switzerland, 18 November 2022 - Leclanché SA (SIX: LECN), one of the world’s leading energy storage companies, announces the completion of the conversion of CHF 41.3 million of debt owed to SEFAM[1] into shares of the Company.

“I would like to thank SEFAM for its continued support to the Company and for agreeing to improve Leclanché’s balance sheet through this debt-to-equity conversion recommended by its Board of Directors.

“Beyond the positive effect this conversion will have on creditors, it will also reduce the Company’s interest bill in the coming months, which will also have a positive effect on its profit and loss account. It will also drive continued investment interest in the company during a period of strong growth for Leclanché in the fast-growing e-Transport sector,” said Pierre Blanc, CEO of Leclanché SA.
