SEC Filing Summary

On October 19, 2026, a merger occurred between Atkore Inc. and Prysmian S.p.A. (through its subsidiary Trinity Merger Sub, Inc.). As a result, Atkore Inc. became a wholly owned subsidiary of Prysmian S.p.A. Common stock was converted into a cash payment of $95.00 per share.

Some options with exercise prices at or above the merger consideration were canceled without any payout. Unvested restricted stock units (RSUs) and performance restricted stock units (PSUs) were deemed fully vested and converted into cash payments. Daniel S. Kelly, VP, General Counsel and Secretary, reported these transactions. The filing indicates that the reporting owner is not subject to Section 16 of the Securities Exchange Act of 1934.
