A City analyst has said that OnTheMarket is “long on rhetoric, short on numbers”, and that it barks rather than bites.

Investment bank Jefferies made its remarks in upgrading its forecasts for Zoopla on the back of its acquisition of uSwitch.

Jefferies raised its revenue estimates for this year by £6m and its earnings before costs (EBITDA) by £1.5m.

The bank says this more accurately reflects uSwitch’s contribution to group earnings this year, with the transaction having completed one month earlier than initial assumptions.

Jefferies says that because of this, “we are tidying up our estimates ahead of the Group’s September year end”.

However, Jefferies – which advised Zoopla on its stock market flotation in summer 2014 – also says that ‘housekeeping’ aside, Zoopla is doing well.

In a note to investors, it says that the threat posed by OnTheMarket is waning as Zoopla grows: “Membership trends reported at the half year continue, the Group is therefore increasing its number of members, which suggests to us that the threat of On The Market (OTM) continues to wane.”

The bank goes on to say that OTM is long on rhetoric and short on numbers, adding: “In our view, OTM continues to make a lot of noise in the trade press, but it is often that empty vessels make the most noise.

“Despite the noise we have not seen OTM reporting actual member numbers for some time, which suggests to us that its bark is worse that its bite.”

Jefferies goes on to say that if Zoopla members “continue to grow, so will our estimates”.

It says: “It is our belief that if Zoopla continues to grow member numbers we could be close to the start of an upgrade cycle at Zoopla on member numbers alone.

“If we couple this with a touch of ARPA growth and enhanced performance at uSwitch, the potential upgrades are, to our mind, very interesting indeed.

“While we believe it is too early to speculate on the quantum of any changes to estimates, it is our assertion that the next few movements will directionally be up not down.”

Last week another analyst, Goldman Sachs, hoisted its price objective for Zoopla from 250p to 276p, although keeping its neutral rating for the stock. Zoopla has a 12-month low of 150.80p and a 12-month high of 286.15p.

Zoopla last year announced its full-year results in late November, and so a similar date is expected this year. It has its AGM on October 1.
