Coherent Corp. (COHR), the photonics and optical components maker formerly known as II-VI Incorporated, has been one of the market's most volatile AI-infrastructure names in 2026. After surging more than 200% over the past year to a 52-week high of $440, the stock has pulled back sharply and now trades near $272. That decline has reignited a simple question investors keep asking: can COHR climb back to the widely discussed $400 level?
The $400 target is not an arbitrary number. In May 2026, Bank of America lifted its COHR price target to $400 from $365 while maintaining a Neutral rating, citing a larger forecast for the AI data-center market. At the same time, the broader analyst consensus has drifted toward the low-$400s, making $400 a natural focal point for both bulls and skeptics. With the stock trading near $272, reaching $400 would require roughly a 47% advance, a meaningful but not outlandish move given how far this stock has already traveled.
Coherent designs and manufactures lasers, transceivers, optical components, and engineered materials used across communications, industrial, and instrumentation markets. Its Datacenter & Communications segment has become the core growth engine, generating about 75% of total revenue after rising 41% year over year in the most recent fiscal quarter. As AI clusters scale to hundreds of thousands of accelerators, optical connectivity is replacing copper for high-bandwidth, long-reach data movement, positioning Coherent as a critical supplier.
COHR's recent price action tells a story of extraordinary momentum followed by a sharp reset. The shares reached $440 in early June 2026 before falling roughly 38% to current levels, with the stock now sitting just below its 200-day moving average near $274. This pullback has occurred despite fundamentally strong results: fiscal third-quarter revenue of $1.805 billion rose 21% year over year, with non-GAAP earnings per share (EPS) of $1.41, and management guided the following quarter to between $1.91 billion and $2.05 billion in revenue.
Several catalysts support a move back toward $400. First, demand visibility is unusually strong: most of calendar 2026 is already booked, with orders extending into 2027 and customer forecasts reaching into 2028. Second, NVIDIA (NVDA) made a $2 billion strategic investment in Coherent and signed a multiyear co-packaged optics (CPO) supply agreement, validating the company's role in AI infrastructure. Third, Coherent's shift to larger 6-inch indium phosphide wafers is expected to lower unit costs and support gross-margin expansion, with management targeting gross margins above 42% over the long term.
The obstacles are equally real. Valuation remains demanding, with a forward price-to-earnings (P/E) multiple near 29x that already reflects much of the AI upside. The Industrial segment, which declined about 16% year over year, continues to drag on overall growth. Heavy investment in new capacity has pushed free cash flow negative, with roughly $1.1 billion in annual capital expenditures against thin operating cash flow. Any slowdown in hyperscaler spending, supply-chain disruption around indium phosphide, or margin disappointment could keep the shares range-bound below $300.
Analyst sentiment is constructive but far from uniform. The consensus rating is Buy, with an average one-year price target near $415. However, the dispersion is wide, ranging from cautious targets below $300 to bullish estimates above $450. Bank of America's $400 target carries only a Neutral rating, signaling that the firm sees incremental upside but believes much of the bull case is already priced in. That mixed tone underscores why the journey back to $400 will likely depend on execution rather than enthusiasm.
From a technical-analysis perspective, $400 functions as both a psychological round number and a prior supply zone below the $440 record high. On the way there, $300 marks the first major resistance level, followed by the 50-day moving average area near $314 and then $350. On the downside, the $264–$274 zone, anchored by the recent low and the 200-day moving average, represents the first meaningful support that bulls need to defend.

A return to $400 for Coherent is plausible but not guaranteed. The strongest supporting factors are record AI-driven order visibility, NVIDIA's strategic endorsement, and structural cost improvements from the 6-inch wafer transition. The primary risks are a rich valuation, an underperforming industrial business, and negative free cash flow during a period of heavy capacity expansion. Investors should watch quarterly gross-margin trends, the pace of the 1.6T transceiver and co-packaged optics ramps, and whether the shares can hold the $264–$274 support zone. For now, $400 remains a credible but demanding objective rather than an easy round trip.
