The National Company Law Tribunal has approved the merger of Arrka Infosec Private Limited, a wholly-owned subsidiary, with parent company Persistent Systems. The IT services firm received the certified order from NCLT's Mumbai bench on Monday. The merger aims to simplify corporate structure, achieve synergy gains and eliminate duplicate procedures. NCLT noted the consolidation would enable effective management, unified control and reduce administrative costs. As Arrka Infosec is wholly owned by Persistent Systems, no new shares will be issued. The subsidiary's issued and paid-up capital will be cancelled on the scheme's effective date, and Arrka Infosec will be dissolved immediately thereafter. Pune-based Arrka Infosec, incorporated in 2012, provides information technology and IT-enabled services.
