It's been a fantastic day for Pets at Home. The pet shop chain's shares are up almost 10% after this morning's better-than-expected annual results.
The 452-strong chain said retail like-for-like sales rose 5.1% in the year, with group-wide comparable store sales up 5.7%.
The rise comes despite the group's pre-tax profits slumping 37.7% to ￡49.6m after it took a ￡40.1m hit on its overhaul of the group's chain of veterinary practices after rapid expansion in recent years.
Chief executive Peter Pritchard said the group was on track to return to profit growth in 2020-21.
