VIENNA: Austrian lighting group Zumtobel posted a higher than expected net loss of 13.4 million euros ($15 million) on Tuesday on an adjusted operating profit of 4.3 million euros, also below the average estimate in a Reuters poll of analysts.

Analysts polled by Reuters had on average expected third-quarter adjusted earnings before interest and tax (EBIT) to remain stable at 7.61 million euros and a net loss of 4.7 million euros.

Zumtobel's earnings will be hit by 25 million euros in special effects this financial year, Chief Executive Ulrich Schumacher said in a letter to shareholders, after previously forecasting a 20-million-euro charge.
