Belden shares declined 10.5% post-earnings, as investor focus shifted from solid quarterly results to a cautious near-term outlook and uncertainty related to the announced Ruckus Networks acquisition. Despite top-line and margin expansion, limited visibility and a measured guidance range sparked concerns about forward growth and integration risk.

• Revenue in Q1 was $696 million, up 11% year-over-year, with 7% organic growth across all major regions.
• Adjusted EPS rose 11% to $1.77, and adjusted EBITDA increased 14% to $118 million; EBITDA margin expanded 40 bps to 17%.
• Guidance for Q2 projects revenue of $735–$750 million and adjusted EPS of $1.95–$2.05, consistent with seasonal patterns but signaling “limited” visibility and a “fluid” macro environment.
• Announced definitive agreement to acquire Ruckus Networks; no guidance for integration impact yet, and near-term results exclude Ruckus.
• Company continues to invest in capacity and systems, but “balanced, measured” commentary and macro caution weighed on sentiment despite past multi-year execution.
