Second-quarter sales by the Swedish company were estimated at 15.5 billion crowns ($1.53 billion), including the Orbit Irrigation acquisition, missing a forecast for 16.4 billion crowns according to Refinitiv Eikon data.

"The strong demand for our robotic mowers continues but low production in the second quarter has resulted in a continued record high order backlog," Chief Executive Henric Andersson said in a statement.

The company will release its full quarterly report on July 15.
