The loss follows Ericsson announcing last week that it was taking a US$2.9-billion charge to write down the value of its assets, in particular its US$6.2 billion purchase of Vonage, which was completed last year.

The 30.5-billion-kronor (US$2.8-billion) quarterly loss compares to net profit of 5.4 billion kronors in the three months to the end of September last year.

Net sales declined by 5% on a reported basis, and by 10% once currency changes are removed.

“Consistent with the rest of our industry, we expect the macroeconomic uncertainty to persist into 2024, which impacts our customers’ investment ability,” said chief executive Borje Ekholm.

“We are addressing these challenges with a focus on elements within our control, namely cost management and operational efficiency,” he added.

Ericsson, which along with its Nordic rival Nokia and China’s Huawei, dominates the market for 5G mobile network communications equipment, announced in February it was cutting 8,500 jobs throughout the world as it tries to cut costs.
