Atkore Inc. shares jumped sharply on the day Prysmian S.p.A. disclosed a definitive agreement to acquire the electrical infrastructure company in an all-cash deal valued at approximately $3.8 billion. Atkore stock climbed 24.8% to reach $79 during the trading session, touching a 52-week high after the transaction and corporate results were announced.
Under the terms of the agreement, Atkore shareholders will receive $95.00 per share in cash for each share of common stock. Prysmian said the per-share cash consideration equates to a roughly 30% premium to Atkore’s closing price of $72.96 on July 31, 2026, and a roughly 57% premium to the company’s closing price of $60.69 on September 29, 2025, which was the last trading day before Atkore launched its initial strategic review.
The strategic rationale that Prysmian cited centers on increased demand for electrical infrastructure amid broader electrification trends and the buildout of AI-driven data centers. Prysmian’s chief executive, Massimo Battaini, was quoted saying: "Electrification, AI-driven data centers and digitalization all require major investments in infrastructure, and they are critical to the modern economy, and the opportunity is substantial in the United States."
Adding to the market reaction, Atkore reported third-quarter earnings per share of $1.92, which exceeded the analyst consensus by $0.14. Revenue for the quarter was $794.8 million, also ahead of the consensus estimate of $781.08 million. Those results provided an additional fundamental catalyst coinciding with the takeover announcement.
Prysmian forecast that the acquisition would produce about $150 million in run-rate pre-tax synergies within three years following closing. The company also presented pro forma fiscal 2025 figures, stating that the combined entity would have reported approximately c22.1 billion in revenue and c2.7 billion in adjusted EBITDA. Prysmian said the deal is expected to be earnings accretive from the first full year after closing.
The transaction remains subject to customary closing conditions, including the approval of Atkore shareholders and regulatory clearances. Prysmian has targeted completion of the deal by calendar year end 2026, pending those approvals and other usual conditions to closing. Both companies' boards gave unanimous approval to the agreement.
U.S. equity markets were broadly positive on the day, with the S&P 500 up 0.5%, the Dow Jones Industrial Average rising 0.7%, and the Nasdaq climbing 0.5%. Market moves in the major indexes were noted as supportive but materially smaller than Atkore’s own price jump, indicating the takeover announcement and the company results were the primary drivers of Atkore’s outsized intraday gain.
Context and market reaction
The combination of a premium acquisition offer, a same-day earnings and revenue upside, and unanimous board endorsements produced a convergence of catalysts that pushed Atkore shares higher. Prysmian quantified expected synergies and disclosed pro forma scale metrics, while also setting a target timeline for closing that hinges on shareholder and regulatory approvals.
Investors will watch the approval and regulatory process and the companies' progress toward realizing the stated synergies, as well as any further updates on timing. For now, the announcement has driven Atkore to its highest share price in the past year during today’s session.
