Siemens AG, Europe's largest engineering company, reported Oct-Dec quarter profit that matched analyst estimates as declines in the health-care and energy-generation operations were offset by gains in other divisions. Profit from so-called industrial operations fell 4.1 per cent to euro 1.8 billion ($2 Billion), the Munich-based company said in a statement. That matched the average estimate of six analysts surveyed by Bloomberg. Revenue increased 5.1 per cent to euro 17.4 billion.
