Revenues at the UK arm of activist investor Atticus fell by about two thirds over the year to March 31, a period during which widespread redemptions greatly reduced the firepower of managers’ pushing for change at companies.

Atticus UK LLP reported a 65% fall in revenues from £4.6m ($5.2m) to $1.6m over the period, according to the its full-year financial statement published at Companies House last week.
