ARN Media’s market capitalisation dropped by a precipitous 19% today, as the market reacted to the news that Jackie Henderson has launched her own court case over the end of the Kyle & Jackie O Show.

The market capitalisation of ARN Media fell to just $73.6m.

The company’s market cap is now dwarfed by both the $82.3m being sought by Henderson and the $85m by Kyle Sandilands, who launched his own Federal Court action last week.

ARN’s market cap has now declined by 61% over the last 12 months.

So far ARN has narrowly avoided the ignominy of being overtaken for market cap by radio minnow Sports Entertainment Group, owner of SEN Radio. The gap between the two companies is now just $3.4m. The valuation of SEN was $74.4m as recently as last Thursday.

Elsewhere on the Unmade Index, it was a better day. While the wider ASX All Ordinaries was up by 0.3%, the Unmade Index, which follows Australia’s listed media and marketing companies, rose by 2.16% to 366.7 points.

Ooh Media bounced by 7.4% while Nine was up by 2.7%. Lower in the table, Pureprofile improved by 8.3%.
