Atkore merger with Prysmian advances as HSR waiting period expires
The U.S. antitrust waiting period for Prysmian’s proposed acquisition of Atkore has expired, allowing the merger process to advance. The next setup is execution risk around the remaining transaction conditions rather than the initial U.S. waiting-period review.
The Hart-Scott-Rodino waiting period for Prysmian's planned merger with Atkore has expired, removing a U.S. procedural hurdle. Other regulatory, shareholder or closing conditions may remain outstanding.
Atkore's latest annual results show revenue of $2.9 billion, down 11.0% year over year, with a -0.5% net margin and diluted EPS of $-0.45 for the fiscal year ended September 30, 2025. Those figures describe Atkore's standalone financial position and are not merger terms or current-quarter results.
For ATKR, the direct mechanism is transaction completion: the company is the acquisition target, so the HSR expiration advances the path toward a change of control rather than changing its operating outlook. Prysmian's economics, consideration structure and any remaining conditions were not detailed.
The next concrete markers are any remaining regulatory decisions, shareholder or court approvals and the closing announcement. The key open questions are the transaction terms, the timetable and whether any further conditions could delay or alter completion.
The HSR clearance removes a U.S. closing hurdle for ATKR, shifting the risk toward remaining merger conditions and timing.
The immediate benefit is procedural: ATKR has cleared a U.S. antitrust waiting-period hurdle, reducing one source of completion risk without establishing the final timetable or economics. The weak annual operating backdrop—$2.9B of revenue, down 11.0% year over year, and a -0.5% net margin—makes the transaction path more important to the equity outcome, but the missing consideration and closing terms prevent a quantified directional call.
The read fails if another regulatory or transaction condition delays, changes or blocks the merger, or if the final consideration is less favorable than expected.
