Why Is COHERENT CORP (COHR) Stock Up Today?

Coherent Corp (COHR) rose 5.85% to $313.31 in early trading on Wednesday, driven by a combination of strong earnings momentum and product innovation in the AI data center sector. The stock opened with a 2.1% gap up and climbed further as the session progressed, reaching a high of $314.15. The move reflects optimism around the company's expanding pluggable optical line system and robust revenue growth in a high-growth industry.

What Happened

Coherent announced an expansion of its Pluggable Optical Line System (POLS) portfolio with a full C-band, high-power variable-gain amplifier in a QSFP form factor for 800G ZR/ZR+ optics. The new product supports 32 dense wavelength division multiplexing (DWDM) waves and 25.6 terabits per second over distances of 2, 200 kilometers, enabling high-speed AI data center networks. This announcement aligns with the company’s broader strategy to meet rising demand for optical connectivity as data centers transition from copper to optical infrastructure.

The stock’s rise also follows strong financial performance. Coherent reported record revenue of $2.05 billion in the latest quarter, a 42% year-over-year increase. The company’s net margin stands at 11.3%, and its trailing twelve-month revenue growth is 22.5%. Analysts highlight that Coherent’s aggressive capacity expansion and margin expansion position it for a higher price-to-earnings multiple.
