Atkore Expands Scope of Strategic Alternatives Review to Maximize Shareholder Value

Board and Management Team Will Consider Options Including a Potential Sale or Merger of Entire Company

Enters into Cooperation Agreement with Irenic Capital Management; Will Expand Board of Directors

Atkore Inc. ("Atkore" or the "Company") (NYSE:ATKR) today announced that its Board of Directors (the "Board") has expanded the scope of its previously announced review of strategic alternatives to include assets outside of its core electrical infrastructure portfolio. As part of this expanded review, the Board and management team will consider a broader range of alternatives to maximize shareholder value, including, among other things, a potential sale or merger of the whole company.

Bill Waltz, Atkore President and CEO said, "The Atkore Board remains steadfast in its commitment to maximize shareholder value, and has authorized Citi and J.P. Morgan Securities LLC to assist us in expanding the scope of our strategic review process."

"As the Board conducts its expanded strategic review process, management will continue to take actions to strengthen the business, including focusing on our core electrical infrastructure business and improving our cost structure to drive profitable growth," said Atkore's Chairman of the Board of Directors.

There can be no assurance that the strategic alternatives review will result in the Company pursuing a transaction or any specific outcome. There is no deadline or definitive timetable set for completion of the strategic alternatives review. Atkore does not intend to make any further public comment on the process unless and until it determines that further disclosure is appropriate or necessary.

Waltz continued, "Due to the Board's decision to expand our strategic alternatives process, I have decided to stay on as CEO through at least the conclusion of the strategic review."

Board of Directors Update

Atkore also announced today it will appoint Franklin Edmonds to its Board of Directors as part of a cooperation agreement with Irenic Capital Management LP (together with its affiliates, "Irenic"). With the addition of Mr. Edmonds, Atkore will expand its Board to ten directors, nine of whom will be independent. Additionally, the Board will form a Strategic Review Committee to oversee, evaluate and provide advice to the full Board regarding its review of strategic alternatives, including a potential sale or merger of the entire Company. Once formed, Bruce Taten will be appointed to serve as a Special Advisor to the Strategic Review Committee.

"We are pleased to welcome Frank to our Board," said Michael Schrock, Chair of the Atkore Board of Directors. "Frank brings valuable industry perspective, coupled with extensive experience analyzing and investing in public and private enterprises, which will complement the current skillsets on the Board. We also look forward to benefiting from Bruce's expertise on the Strategic Review Committee. We believe that Frank and Bruce will provide important insights as we conduct our thorough review to determine the best path forward for the Company and shareholders."

Pursuant to the cooperation agreement, Irenic has agreed to customary standstill and voting commitments, and other provisions. The cooperation agreement will be filed on a Current Report on Form 8-K with the U.S. Securities and Exchange Commission (the "SEC").

"We appreciate the Board's collaborative approach, and we believe the Company is taking the right steps to achieve our shared goal of value creation," said Adam Katz, Co-founder and Chief Investment Officer of Irenic. "Irenic invested in Atkore because we believe the Company is well positioned to successfully unlock significant value, and we believe the Board and the executive leadership team are committed to taking actions that advance the interests of all shareholders."
