SCHMID (SHMD), Canatu (CNTPF): Sold-Out Fabs Defer Line Changes

On 2026-08-25, SCHMID Group N.V. (SHMD) and Canatu Oyj (CNTPF) described the same condition on their respective H1 2026 earnings calls: their customers' plants are running flat out against a committed order book, so any change that can be deferred inside a running line is being deferred, and the capacity that still has to be added is being added in newly built factories instead [1][2]. SCHMID booked EUR 52.3m of orders in the first eight weeks of its third quarter, while the second reactor Canatu delivered has waited roughly two years without customer site acceptance [1][2].

Why a fully loaded line stops accepting change

Start with what the two companies sell. Canatu makes pellicles — thin protective membranes mounted over a photomask to keep particles off it and lift yield — and what it sells to chipmakers is the reactor that produces them. Once delivered, the sale is complete only after the tool passes site acceptance at the customer [2]. SCHMID sells wet-process and plating equipment to plants that make IC substrates, the carrier layer that sits between the chip and the circuit board [1].

Both businesses used to depend on the customer doing things inside a plant already running: adding a few tools in an existing building, or setting aside time to qualify a new material. With AI-driven demand far ahead of supply, leading-edge lines and IC-substrate plants are fully loaded delivering orders already signed, and downtime now carries an explicit price. Canatu's CEO said the fastest way to add supply is to improve yield, but semiconductor manufacturing has a long chain and is extremely sensitive to change, and the worst thing that can happen is a week of trouble with a lithography tool — so customers under order-book pressure are being careful [2].

So anything deferrable is deferred, and the expansion that must happen is moved out of the running plant. Scarce in-house engineering goes to output first and the qualification queue lengthens, while added capacity takes the form of a new factory bought as a whole line [1][2]. Which side a supplier lands on depends on whether its product improves a running line or forms the content of a new one.

Orders change scale in three months while an acceptance test sits still

The numbers moved quickly on SCHMID's side. Order intake was EUR 13.6m for all of Q1 2026, then EUR 52.3m in the first eight weeks of Q3, EUR 96.6m year to date, and a record EUR 89m backlog — against just over EUR 90m of orders in all of 2025 [1]. The company's CSO gave the reason directly: a shortage of IC substrates appeared in the fourth quarter of 2025, the large substrate makers stopped incremental investment in existing plants during Q1 2026 and planned staged new factories instead, and those new plants began taking equipment from late Q2 [1]. The buyer changed too, from PCB customers to semiconductor customers, who management says are used to paying higher prices — a positive effect on gross margin [1].

On Canatu's side the same condition shows up as time standing still. The second reactor delivered to a customer has gone roughly two years without site acceptance. Management explained that customers differ in the resources they put into qualifying a new technology, and that a customer with a very large order book can easily prolong the process [2]. The company generated no meaningful consumable revenue in the first half, and the CFO said 2026 revenue will decline significantly from EUR 15.6m in 2025 [2].

The same deferral has already reached another company's income statement. Photomask maker Photronics said on 2026-05-28 that industry fab utilization is higher than normal, that fabs have been unable to accommodate additional design releases from some customers, and that many chip OEMs are continuing production on current designs while delaying new ones [3]. Photomask demand tracks new designs rather than volume, so revenue that quarter was $209.9m against $211.0m a year earlier — essentially flat — while operating income fell from $55.7m to $42.2m and gross margin from 36.9% to 31.3% [4]. Three unrelated products, one reason for the delay.

Equipment orders move from the retrofit budget to the new-plant budget

What changes first is who approves the same money. Equipment vendors used to face a running plant's retrofit budget and sold tools a few at a time; now the order is set by a new factory's construction budget and covers a whole line. Orders get larger and more complete but convert more slowly — SCHMID says most of this recent intake becomes 2027 revenue [1].

The boundary needs stating. MKS Instruments said on 2026-08-06 that some customers are still debottlenecking, even turning mothballed tools back on [5], so the halt in incremental investment inside existing plants can only be confirmed at the IC-substrate tier SCHMID serves and cannot be extended to semiconductor equipment as a whole. ACM Research expects production qualification of two new platforms by the end of 2026 [6], which on its face runs against the idea that no new technology gets qualified during a boom; the possible explanation is that those platforms go onto new lines, but nothing in the disclosed material supports it.

Three things are checkable from here: when SCHMID's backlog converts to revenue, whether Canatu's second reactor passes site acceptance, and MKS's statement that chemistry volume follows a tool installation by 24 to 30 months [5].

Companies exposed to the same mechanism

• Onto Innovation (ONTO): sells semiconductor metrology and inspection systems and lithography for panel-level packaging, and management describes value-chain demand as gated by new fabrication facilities coming online [7]; if expansion concentrates in new plants, its order timing is tied to those construction schedules too.
• ACM Research (ACMR): sells wet-process cleaning and plating equipment, and its panel-level horizontal plating platform addresses the same process step SCHMID is equipping, with the first two orders for that platform booked in Q2 2026 [6]; how far the new substrate plants have been built determines when such tools are ordered.
• MKS Instruments (MKSI): supplies the plating chemistry consumed only after the equipment is installed, and management says chemistry follows a tool installation by 24 to 30 months before it scales with volume production [5]; this round of new-plant construction reaches its revenue later than it reaches the equipment vendors.

"Well, we have seen in the first quarter, we have recognized, or let's put it that way, in the last quarter of 2025, we have recognized a shortage in IC substrates. This is what I mentioned with flip GPGA substrates. And in the first quarter of 2026, the big substrate manufacturer were making plans to stop and stopped incremental investments and made plans for stage investment through new factories. And this took some time in Q1 and they made it on the way in Q2. And this is what we currently recognize. These new factories are being built and are being equipped with new equipment. And this is what we started to recognize in the late Q2 and already in Q3."
