Shares of Coherent Corp. NYSE:COHR rose 12.4% on Tuesday morning as investors speculated that a suggested U.S. ban might steer AI-optics demand to American manufacturers. The stock was trading at $323.86 at 10:53 EDT, off its session peak of $346.
The decision boosted market capitalization by about $7.0 billion. In addition, the fiscal 2027 consensus P/E increased to 38.7 times, up from 34.4 times at the close on Monday. This valuation reset occurred ahead of any formal rule language.

The Federal Communications Commission is preparing rules that would limit the use of new Chinese optical transceiver models. According to officials, the proposal is expected to be made public within the year. Sources noted that the measure could be revised or halted before publication.
“Transceivers definitely pose a risk,” Beacon Global Strategies’ Divyansh Kaushik said. The planned restrictions are designed to safeguard data centers against malware, data theft and operational disruption. China’s embassy cautioned that Beijing might retaliate against actions that affect its interests. Reuters
The supply pool in focus is considerable. Zhongji Innolight Co., Ltd. SHE:300308 is estimated to control 27% of the worldwide data-center transceiver market. At present, Coherent and Lumentum do not have the necessary scale to entirely supplant Chinese vendors. Amazon.com, Inc. NASDAQ:AMZN and other cloud service providers may experience increased costs.
Policy prospects contrasted with supply limitations
| Indicator | Verified figure | Investor read-through |
|---|---|---|
| Innolight global transceiver market share | 27% | Possible share available |
| Coherent Q3 revenue from datacenter | 75.4% | Significant policy exposure |
| China’s portion of global indium production | 70% | Upstream concentration |
| Six-inch InP wafer price change | +250% to $5,000 | Risk to margins and production |

Coherent’s notable market response is due to its business composition. Datacenter and Communications units brought in $1.362 billion in the most recent quarter, accounting for 75.4% of total revenue, with growth of 40.6% compared with a year earlier. Industrial revenue declined by 16.1%.
Coherent’s revenue breakdown for the third quarter of fiscal 2026
| Segment | Revenue | Share of total | Year-over-year change |
|---|---|---|---|
| Datacenter and Communications | $1.362 billion | 75.4% | up 40.6% |
| Industrial | $444.0 million | 24.6% | down 16.1% |
| Consolidated | $1.806 billion | 100% | up 20.5% |
Coherent’s published figures form the basis for growth and mix calculations.
Chief Executive Jim Anderson in May pointed to “exceptionally strong demand across our datacenter and communications businesses.” The management team had been boosting production to accommodate that demand.
The trade dispute is also causing issues earlier in the supply chain. In 2024, China was responsible for 70% of the world’s indium production. Export controls contributed to a 250% surge in prices for six-inch indium-phosphide wafers, reaching around $5,000. Coherent is increasing wafer output in Texas twofold this year and has a further expansion scheduled for late 2027.
Coherent is scheduled to announce results after the market close on August 12. The midpoint of its non-GAAP EPS guidance stands at $1.62, in line with the consensus analyst forecast. Revenue guidance at the midpoint is $1.98 billion, suggesting a 9.7% increase from the previous quarter.
August 12 marks key earnings test
| Metric | Q3 actual | Q4 guidance or estimate | Implied hurdle |
|---|---|---|---|
| Revenue | $1.806 billion | $1.91–$2.05 billion | Midpoint represents a 9.7% increase |
| Non-GAAP gross margin | 39.6% | 39.0%–41.0% | Midpoint improves by 40 basis points |
| Non-GAAP EPS | $1.41 | $1.52–$1.72 | Midpoint rises 14.9% |
| Q4 EPS consensus estimate | — | $1.62 | Matches guidance midpoint |
| Fiscal 2027 EPS consensus estimate | — | $8.37 | 38.7 times the current price |

The figures indicate that margin conversion may have greater significance than top-line orders. A ban has the potential to strengthen Coherent’s market standing. However, supply constraints and increased costs for customers could limit the upside for earnings.
Risks: The FCC might alter or withdraw the proposal. China could respond with countermeasures, and cloud clients might postpone buying. Supply limits on indium-phosphide could offset price improvements. With a 38.7-times consensus multiple for fiscal 2027, there is little margin for disappointing guidance.
