March 09, 2026

Coherent Corp. (NYSE: COHR) was added to the S&P 500 index effective March 23, 2026, following an announcement made on March 9, 2026. The inclusion reflects the company’s market capitalization, financial strength, and growing presence in the photonics sector, positioning it among the benchmark’s leading U.S. large‑cap equities.

Coherent’s core business centers on high‑performance optical interconnects that enable next‑generation artificial‑intelligence data‑center infrastructure. The company’s networking segment, which accounts for roughly 72 % of sales in Q2 FY2026, drives most of its revenue growth. In Q1 FY2026, Coherent reported revenue of $1.58 billion, up 17 % year‑over‑year, and a non‑GAAP gross margin of 38.7 %. The company’s fiscal‑year 2025 revenue of $5.81 billion remains a record high, underscoring the strength of its high‑margin data‑center and communications businesses.

Management highlighted the strategic partnership with NVIDIA, which includes a $2 billion equity investment and a multi‑billion‑dollar research, development, and supply‑chain agreement focused on photonics for AI data centers. CEO Jim Anderson said, "Joining the S&P 500 is a testament to the strength of our team, the power of our technology portfolio, and the trust our customers have placed in us. As optical interconnects and photonic solutions become foundational to scaling next‑generation AI data center infrastructure, Coherent is uniquely positioned to drive innovation and deliver enhanced value to our shareholders." NVIDIA’s chief executive, Jensen Huang, added, "Computing has fundamentally changed. In the age of AI, software runs on intelligence with tokens generated in real time by AI factories for every interaction and every context. With Coherent, NVIDIA is pioneering next‑generation silicon photonics to enable AI infrastructure at unprecedented scale, speed and energy efficiency."

The S&P 500 inclusion is expected to increase liquidity for Coherent’s shares and broaden its investor base, potentially enhancing the company’s visibility and access to capital markets. The move also signals confidence in Coherent’s strategic pivot to a pure‑play AI infrastructure provider, as the company divests non‑strategic businesses and focuses on high‑growth, high‑margin segments. The partnership with NVIDIA further strengthens Coherent’s competitive position, providing a robust pipeline of demand for its photonic solutions in the rapidly expanding AI data‑center market.

The announcement underscores Coherent’s trajectory as a leader in photonics, with strong financial performance, a clear focus on high‑growth data‑center and communications markets, and a strategic alliance that positions it at the forefront of AI infrastructure development. The inclusion in the S&P 500, combined with the NVIDIA partnership, is likely to attract passive fund flows and reinforce investor confidence in the company’s long‑term growth prospects.
