OnTheMarket has announced that it now has listing agreements with over 8,500 agent branches – an addition of 3,000 since it listed on the stock market on February 9.

OTM said this represents growth of over 54% in under four months. It said it believes 45% of UK agency branches now list with it.

CEO Ian Springett said the latest milestone was achieved just two weeks after reaching 8,000 offices.

He said: “In sustaining this pace of expansion, we are very strongly encouraged by the growing agent support and feedback to our proposition.”

In response, the share price ended the day up 5p at 181p, well above the 165p that the shares were first offered to investors.

OTM also earned itself the first ‘buy’ rating from an analyst.

Alastair Stewart of Stockdale Securities said the rate of new branches joining OTM appears to be accelerating, and that TV and outdoor advertising seems to be generating “heavier engagement from consumers – a key tool in attracting further agent take-up”.

He also pointed to increasing traffic to the portal and 1m email alerts set up by consumers.

He said there was “further and possibly growing momentum in agent sign-ups and encouraging engagement with their target consumers”.
