SMG may reduce its current £155m net debt by selling either or both of outdoor advertising business Primesight or cinema advertising business Pearl & Dean. The former is valued at around £60m but the latter is believed to be less attractive.

Brokers expect the results to show profits down from £18.8m to around £11.5m.
