The artificial intelligence (AI) infrastructure build-out is hitting a physical wall. As next-generation processors push past the 1,000-watt threshold, legacy packaging substrates are failing to dissipate the extreme heat generated by these clusters. Data center operators are discovering that without advanced thermal materials, the world's most powerful chips will throttle themselves to prevent hardware failures. Effective thermal management is no longer an optional upgrade; it is a hard constraint on performance.
While the broader market fixates on software and chip design, the physical bottlenecks of AI hardware present a compelling investment thesis. Recent macroeconomic jitters have dragged shares of Coherent Corp. (NYSE: COHR) down about 12% in the past five days. This price drop is due to broader de-risking in the semiconductor sector, creating a severe disconnect between Coherent's technical valuation and its operational reality.
