March 24 (Reuters) - Janus Henderson ( JHG ) said on

Tuesday that Trian and General Catalyst have raised their bid to

acquire the asset manager to $52 per share.

The new offer, which represents a 25% premium to Janus'

unaffected stock price and is $3 per share higher than the

previous bid, comes amid a high-stakes battle with Victory

Capital ( VCTR ), which has maintained its pursuit of the

company.

"Trian and General Catalyst have already made significant

progress toward closing and have a clear path to satisfying all

outstanding conditions," Janus said.

Trian, Janus' largest shareholder with ​a 20.7% stake, had

on Friday raised concerns about Victory's sweetened offer.
