Tue Apr 30

Ad hoc announcement pursuant to Art. 53 LR

YVERDON-LES-BAINS, Switzerland, April 30, 2024 – In its decision of April 29, 2024, SIX Exchange Regulation AG approved an extension of the publication deadline of Leclanché’s (SIX: LECN) 2023 annual report until May 31, 2024.

The Company has requested an extension for submitting its 2023 annual report. This request comes as a result of significant internal optimisations carried out last year, which have greatly enhanced the Company’s value model and financial framework. The 2023 consolidated accounts now include three new entities, each with its own set of accounts, necessitating a more intricate consolidation process than in previous years.

These strategic enhancements include the transformation of Leclanché’s specialty business unit into a fully-owned subsidiary, Leclanché SBS SA, and the establishment of Leclanché Technologies SA. This new subsidiary consolidates all the Company’s intellectual property rights and patents, facilitating the revaluation of these assets within an IP box, effective from January 1, 2024.

Additionally, Leclanché has reorganised its involvement in a key solar and storage project in St. Kitts through Leclanché St Kitts Energy Holding Ltd. Following a pivotal agreement last year with Leclanché’s then-joint venture partner, Leclanché has now become the sole owner of this special purpose company.

Leclanché is releasing its unaudited key financial figures for the year 2023:

In 2023, the Company’s consolidated income reached CHF 18.7 million, with customer revenue achieving CHF 17.1 million, marking a notable increase from the CHF 7.8 million reported in the first half of the year. Despite a modest decline in revenue recognised under IFRS compared to 2022, it is important to highlight the CHF 2.8 million in net deferred revenues[1] on the Balance Sheet. This represents additional invoiced amounts to customers that are not yet recognised as revenue, underscoring Leclanché’s prudent financial management.

The Company recorded an unaudited net loss of CHF (67.5) million for the year, which is a substantial improvement from the CHF (85.6) million loss in 2022. This improvement was primarily due to reduced operating and financing costs.

The balance sheet remained stable as of December 31, 2023, with total assets increasing to CHF 108.5 million from CHF 90.8 million in 2022. This financial stability is a testament to the careful and strategic planning.

The Company’s ongoing commitment to growth and innovation continues to propel its success and lay the groundwork for future opportunities. The board remains optimistic about the Company’s ability to generate value for its shareholders and drive sustainable growth.

In its decision of April 29, 2023, SIX Exchange Regulation AG requested Leclanché to insert the below excerpt in this ad hoc announcement:

  1. The exemption request of Leclanché (Issuer) dated 26 April 2024 regarding an extension of the deadline to publish its 2023 annual report and to file such report with SIX Exchange Regulation AG until 31 May 2024 at the latest is granted with the following reservation (lit.
