Context

The payment was made pursuant to the Merger Agreement dated October 29, 2025, under which NEC completed a merger with CSG on May 14, 2026; each CSG common share and each unvested RSA/PSA converted into the right to receive $80.70 cash (less withholding).
The inclusion of RSAs and PSAs means some of the disposed shares were unvested awards that were converted into cash subject to vesting-related terms per the agreement. This was a corporate cash-out from a merger rather than a routine insider sale on the open market.
