Media industry veteran John Rockliff has taken a 4.42% stake in Ebiquity, the AIM-listed marketing analytics and media consultancy, according to a regulatory filing made public today. The move by Rockliff, a former chief executive of media buying giant GroupM and a well-known activist investor, has drawn attention to the company's ongoing turnaround efforts.
Ebiquity, which helps advertisers measure the effectiveness of their media spend, has been navigating a tough advertising market. The company reported a statutory loss before tax of £7.8 million for the year ended December 2025, though it noted improved gross profit margins and cost reductions. Shares in the firm have fallen sharply over the past two years, closing at 23.5p on Friday, valuing the business at roughly £28 million.
Rockliff's stake-building is seen by analysts as a signal that he believes Ebiquity's restructuring programme, under chief executive Nick Waters, can deliver value. His previous investments in media and marketing services firms have often preceded calls for strategic changes or boardroom shake-ups. 'Rockliff has a track record of identifying underperforming assets in the marketing services space and pushing for operational improvements,' said an analyst who asked not to be named.
The FTSE AIM All-Share index has been broadly flat this year, but small-cap stocks like Ebiquity remain sensitive to investor sentiment and sector headwinds. For UK pension holders with exposure to smaller company funds, the stake could be a precursor to a more active engagement that might boost shareholder returns. However, there is no guarantee of a near-term uplift, and the company's performance remains tied to the broader advertising cycle.
Ebiquity has not yet publicly commented on Rockliff's stake. The company is due to report its half-year results in September, which will provide a clearer picture of whether its cost-cutting and client wins are gaining traction. Investors will be watching closely for any signs that Rockliff intends to seek a board seat or push for a sale of the business.
