German battery maker Varta AG 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 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.
