March 23 (Reuters) - Victory Capital ( VCTR ) on Monday fired back at Nelson Peltz's Trian over the criticism of its latest $8.6 billion proposal for asset manager Janus Henderson ( JHG ), saying the activist was making "efforts to blanket market with misinformation".

San Antonio, Texas-based Victory said recent reports regarding the purported views of Janus' employees and clients on the Victory deal were an attempt to "manufacture uncertainty" in the market around its ability to close the proposed transaction.

Trian, Janus' largest shareholder with ​a 20.7% stake, had on Friday raised concerns about Victory's sweetened offer, which rivals ​its own take-private deal.

Trian did not immediately respond to Reuters' request for comment.
