Beijing controls the chokepoint in the optical component supply chain that Washington's export controls cannot address, leaving Lumentum, Coherent and AXT exposed to a licensing risk that most investors have priced out. Every shipment of the compound semiconductor wafers that power AI data-center lasers requires a Beijing export permit, a dependency U.S. policy has done nothing to loosen.
Market-intelligence firm LightCounting now sees optical transceiver demand running 30 percent above supply, with the laser shortage extending into the middle of 2027 — up from its April forecast that the squeeze would ease by the end of 2026. Its July report raised 2026 growth to 73 percent, but warned that customers have started double ordering as almost every transceiver component turns scarce, inflating backlogs that may not survive the supply catch-up.
Lumentum reports earnings Aug. 11 with guidance of $960 million to $1.01 billion in revenue, up from $500 million a year earlier; Coherent follows Aug. 12 with $1.91 billion to $2.05 billion, up from $1.53 billion. Strong growth is already consensus, so the beats will not move shares — what will is how much of each company's wafer supply runs through China, and whether anyone pays cash up front to lock in wafers, a measure of how little faith buyers have in the open market.
The cleanest way to own the shortage is also the most direct way to own the licensing risk. AXT grows every wafer in China, needs a Beijing permit for every shipment and holds stakes in 10 Chinese suppliers, making it the biggest political dependency in the chain. The non-Chinese alternatives are duller. IQE, a Welsh wafer maker with plants in Britain, the U.S. and Taiwan, raised its 2026 growth guidance to above 30 percent from 20 percent on July 21, though it lost 37 million pounds before tax in 2025. Korea Zinc, among the largest refiners, bought Nyrstar's U.S. assets on April 1 and is developing a $7.4 billion Tennessee smelter with U.S. government backing, with indium among 13 planned products targeted for 2029 — a reminder of how long a real fix takes.
The bear case is the backlog, not the shortage
The risk runs both ways. If Beijing extends Announcement No. 10 to refined metal, everything downstream reprices at once. The Defense Logistics Agency has already asked for bids to stockpile up to 403 tons of indium over three years — more than a third of a year's global output — a purchase that shows the U.S. government considers a supply disruption credible enough to prepare for now.
LightCounting's data show transceiver sales turning down about six months before cloud capital spending does, and its model has that spending slowing from roughly 70 percent growth this year to 30 percent next year. If so, the turn in optics would arrive before the news that explains it. Coherent's book into 2028 deserves that caveat, as does any backlog built on double orders.
The market was right to identify optics as a bottleneck. Its mistake was treating every company in the chain as the same trade. Scarcity rewards businesses that control qualified wafer supply, but AXT's advantage comes bundled with the sector's largest geopolitical dependency. From here, returns depend less on who reports the biggest backlog than on who can keep shipping when supply catches up — or when Beijing tightens the gate.
