Oh dear. This ShareScope report has not turned out as I first hoped.
I had wondered whether Brave Bison — an £83 million “next-generation marketing and technology partner for global brands” — might have been a dynamic small-cap suitable for my portfolio.
You see, Bison suddenly loomed into view the other week after acquiring a 28% stake in System1 — an advert-testing business in which I am a shareholder — through a somewhat remarkable transaction.
System1’s founder John Kearon exchanged his entire System1 shareholding for Bison shares worth £7 million, and effectively told the market Bison had become a better investment than his old company.
I therefore asked myself whether I should follow Mr Kearon and switch from System1 into Brave Bison as well.
Indeed, Bison — unlike System1 — appears to be performing very well at present. The group’s January update confirmed net revenue, adjusted Ebitda and net cash had all finished 2025 “ahead of consensus expectations“.
But after delving into Bison’s history, I just could not get comfortable with what has been a very hectic acquisition strategy. Simply put, I don’t foresee Bison delivering the progress necessary to re-rate its shares to a premium valuation.
Let’s take a closer look.
