Coherent’s breakout still looks real because the story is no longer just "AI demand is strong"; it is that optical capacity is becoming the constraint. The clearest proof came on June 16, when the company disclosed a CHIPS Act letter of intent for up to $50 million to expand its Sherman, Texas indium phosphide facility, with plans to double manufacturing production space and quadruple wafer capacity. That is not how a company behaves when demand is the problem. With COHR already growing revenue 23.4% year over year and carrying a Momentum component of 100 inside the TickerSpark Score, the market is treating Coherent as a scarce supplier to the AI buildout, and that read looks right.
The most important fact here is that Coherent is adding supply as fast as it can. The March 2 strategic agreement with NVIDIA was unusually explicit: a $2 billion investment, a multibillion-dollar purchase commitment, and future access and capacity rights for advanced laser and optical networking products. When a customer of that caliber is locking in capacity rather than simply placing routine orders, it tells us the bottleneck is upstream manufacturing throughput.
The financial trend is already moving in the right direction, which makes this more than a concept stock. Revenue is up 23.4% year over year, EPS growth is running at 71.7%, and net income growth is 131.6%. Just as important, Coherent has beaten consensus EPS in 7 straight reported quarters, including the May 6 quarter when it posted $1.41 against a $1.39 estimate. That consistency matters because it suggests the capacity ramp is not just a slide-deck promise; it is showing up in operating execution.
The market is also rewarding that execution with unusual persistence. COHR is up 100.5% year to date, outperforming the Technology sector by 72.5 percentage points, and the stock remains above both its 50-day moving average of 361.71 and its 200-day moving average of 227.06 even after today’s 7.6% drop. That is exactly what leadership looks like in a volatile tape: sharp pullbacks, but no real technical damage. The TickerSpark Score backs that up with a 74 overall, driven by elite Growth at 95 and perfect Momentum at 100.
The obvious pushback is valuation. A 185.8x trailing P/E, 10.22x sales, and 59.72x EV/EBITDA leave no room for a sloppy quarter, and those multiples look stretched next to peers like TRMB at 25.94x earnings or TDY at 30.81x. Insider activity does not help the optics either, with 6 recent sell transactions totaling $2.16 million and no open-market buys.
That still does not break the bull case because Coherent is not being valued like a steady industrial hardware name. It is being valued like a scarce enabler of AI networking throughput, and the operating data supports that treatment better than the bears admit. Profitability is not elite yet, but a 10.3% operating margin and 37.0% gross margin paired with 23.4% revenue growth say this is a scaling story, not a hype-only one. The real risk is not that demand disappears; it is that expectations are high enough that any delay in the InP ramp or CPO commercialization would hit the stock hard.
That leaves COHR looking like a stock to own on controlled pullbacks, not a name to fade because the multiples look uncomfortable. We would respect the volatility, but the setup still favors the bulls as long as the company keeps proving that added capacity converts into revenue and earnings. Mid-August earnings matter because another clean beat would reinforce the idea that the bottleneck thesis is monetizing in real time.
The trigger that would change our mind is straightforward: if management stops talking about rapid capacity expansion to meet demand, or if growth starts decelerating sharply while valuation stays extreme, the premium breaks. Until then, the combination of a CHIPS-backed expansion, NVIDIA-linked capacity commitments, and a 7-for-7 earnings beat streak keeps this in leadership territory. We see Coherent as one of the cleaner ways to own the AI optics bottleneck rather than a crowded winner running on fumes.
