Item 1.01. Entry into a Material Definitive Agreement.
On November 20, 2025, Atkore Inc. (the “Company”) announced that it has entered into a cooperation agreement (the “Cooperation Agreement”) with Irenic Capital Management LP and certain of its affiliates (collectively, “Irenic”).
Pursuant to the Cooperation Agreement, the Company has agreed to, among other things: (i) increase the size of the Company’s Board of Directors (the “Board”) by one (1) director and appoint Franklin S. Edmonds, Jr. (the “New Director”) to the Board to fill the vacancy created by such increase, with an initial term expiring at the Company’s 2026 annual meeting of stockholders (the “2026 Annual Meeting”), (ii) establish a committee of the Board (the “Strategic Review Committee”) consisting of no more than five (5) directors, including the New Director, to oversee, evaluate and provide advice to the Board regarding its review of strategic alternatives and (iii) on or prior to May 20, 2026, under certain circumstances as described in the Cooperation Agreement, increase the size of the Board by one (1) director and appoint a new director to be mutually agreed upon by the Board and Irenic, provided that at such time Irenic beneficially owns a “net long position” of, or has aggregate net long economic exposure to, at least 1.5% of the Company’s then outstanding common stock. Pursuant to the Cooperation Agreement, the Company has also agreed to nominate the New Director for election to the Board at the 2026 Annual Meeting.
The Cooperation Agreement provides for customary director replacement rights, pursuant to which the Company and Irenic have agreed to cooperate in good faith to select a mutually agreeable replacement director in the event that the New Director ceases to serve as a director for any reason prior to the expiration of the Cooperation Period (as defined below), provided that at such time Irenic beneficially owns a “net long position” of, or has aggregate net long economic exposure to, at least 1.5% of the Company’s then outstanding common stock.
Pursuant to the Cooperation Agreement, Irenic has agreed to, among other things: (i) irrevocably withdraw its nomination notice regarding its slate of proposed director nominees for election at the 2026 Annual Meeting and (ii) abide by certain customary standstill restrictions, voting commitments, and other provisions, including a mutual non-disparagement provision during the Cooperation Period.
In addition, pursuant to the Cooperation Agreement, the Company agreed to enter into a consulting agreement to engage Bruce M. Taten to serve as a special advisor to the Strategic Review Committee.
The “Cooperation Period” means the period from November 20, 2025 until the earlier of (x) November 20, 2026 and (y) the date that is thirty (30) calendar days prior to the notice deadline under the Company’s By-laws for stockholders to submit stockholder nominations of director candidates for election to the Board at the Company’s 2027 annual meeting of stockholders. The Cooperation Agreement will terminate upon the expiration of the Cooperation Period.
The foregoing description does not purport to be complete and is qualified in its entirety by reference to the Cooperation Agreement, a copy of which is attached hereto as Exhibit 10.1 and is incorporated by reference herein.
