June 20 (Reuters) - German battery maker Varta AG ( VARGF )

on Thursday said it would cut its full-year revenue

forecast for 2024 due to the declining demand in the energy

storage market.

The German firm now expects revenue in the range of 820

million euros ($877.56 million) and 870 million euros, compared

with the previous forecast of at least 900 million euros.

In April, the firm said it may not meet targets set under

its year-old restructuring plan with a majority shareholder

Michael Tojner after key client Apple ( AAPL ) cut production of

its AirPods headphones.

"We are also having a negative impact on revenue development

in 2024", the Ellwangen-based firm said, adding that it will

impact the wide forecast range.

In February this year, it postponed the publication of its

2023 financial results following a cyber attack that halted

production for weeks.
