Ad hoc announcement pursuant to Art. 53 LR

Leclanché announces extension of the publication deadline for the 2023
annual report and releases its unaudited 2023 key figures.

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:
