Clearfield is trading 14.8% down at $28.77 after the company sharply lowered its full-year 2026 revenue and profit outlook, overshadowing a third-quarter earnings beat.
- The downward revision stems from persistent industry demand constraints, which outweighed reported sales growth and better-than-expected quarterly results.
- Investors remain focused on the weaker long-term guidance despite a significant new $22 million hyperscale data center order.
- The sharp decline occurred during a thin after-hours session as the market reacted to the lowered forward-looking projections.
