Management Comments

• "Our preliminary second quarter results were directly impacted by a project delay from a single customer. In addition, margins reflected the current elevated component and freight cost environment."

• "Outside of this customer-specific dynamic, we're encouraged by the continued strength of our optical networking business, the opportunities we're seeing with customers and end markets, and the innovation pipeline that continues to expand our addressable market."

Industry Context

Key Dates

Recommendation

The company has missed its Q2 guidance for revenue and margins, and earnings per share missed analyst consensus, primarily due to a customer project delay and elevated costs. While management points to underlying strengths in optical networking and future opportunities, the near-term financial performance is concerning. The outlook for Q3 shows continued margin pressure. A 'hold' recommendation is appropriate pending the release of final results and further clarity on the resolution of the customer delay and cost pressures.
