Analysis · ATKR · Manufacturing
A stockholder lawsuit filed September 20 seeks to enjoin the October 7 vote on the $95/share Prysmian acquisition, alleging the proxy statement was misleading. Atkore denies the claims but voluntarily supplemented the proxy with extensive financial advisor valuation details — including Citi's DCF range of $65.70-$104.35 and J.P. Morgan's DCF range of $84.25-$119.50 — to preempt further litigation. The board continues to unanimously recommend approval. The litigation adds uncertainty to a deal already facing a $115.9M breakup fee, though the supplemental disclosures may reduce the risk of a successful injunction.
