Jan 26 (Reuters) - Swedish truck maker AB Volvo reported a slightly smaller rise than expected in fourth-quarter core profit on Thursday and proposed an extra dividend.

Adjusted operating profit rose to 12.2 billion crowns ($1.19 billion) from 10.1 billion a year earlier, against 12.5 billion seen on average by analysts in a Refinitiv poll.

Volvo proposed an ordinary dividend of 7.00 crowns per share, and an extra dividend of the same amount, for 2022.
