Data center and AI demand is no longer confined to the chip aisle. This quarter, 45 companies mentioned it in their filings, equal to 32.1% of the companies that filed in the window. In the same-length window one quarter earlier, the share was 23.7%, even though 57 companies flagged the topic then.
That is a 1.36x quarter-over-quarter move in share. In plain English: the theme became a bit more common, not ubiquitous. The list runs from semiconductor and optical-component makers to security, software, industrial, and construction companies. Management teams are increasingly using the same phrase to explain both growth and operational strain.
Marvell Technology put the upbeat version plainly in its quarterly filing:
"Strong revenue growth from our data center market was driven by AI-related demand for a broad range of our products, including electro-optics, custom, storage, and switching."
Marvell Technology / 10-Q / 2026-08-28
AI demand, in Marvell's account, is not attached to one product category. It is reaching across the company's data center portfolio.
Coherent supplied the larger receipt, with a number attached:
"Revenues increased $1,124 million, or 43%, in the Datacenter & Communications segment, with increases in datacom driven primarily by ongoing strong AI datacenter demand and growth in our telecom revenue due to higher demand in the data center interconnect and the telecom transport business."
Coherent / 10-K / 2026-08-14
That filing ties AI data center demand to both datacom and the infrastructure connecting data centers, not just the computing inside them.
The same demand showed up in Fabrinet's explanation of customer activity:
"This increase was primarily due to an increase in our key customers’ demand for both data center products and communications infrastructure products."
Fabrinet / 10-K / 2026-08-18
Fabrinet's wording is less breathless, but it makes the same point. The filing theme is traveling down the supply chain, into companies that sell components and manufacturing services rather than branded AI systems.
Methode Electronics described data center growth alongside other industrial demand:
"The increase was primarily driven by higher sales volume and mix in the Industrial segment due to organic growth in the data center business and an increase in demand for on-highway and off-highway lighting products (including customer recoveries)."
Methode Electronics / 10-Q / 2026-09-02
Here, data center demand is one part of a broader industrial mix. That matters because the quarter's increase is not simply a parade of pure-play AI companies repeating one another.
There is also a less comfortable version. OSI Systems said the demand is colliding with constrained memory supply:
"We have experienced tighter supply conditions and increased costs for certain memory associated and semiconductor components, reflecting a broader global imbalance between supply and demand for memory used in data center and AI related infrastructure."
OSI Systems / 10-K / 2026-08-21
And Napco Security described the risk prospectively:
"Increased demand for semiconductors and electronic components driven by artificial intelligence (\"AI\") infrastructure and data center expansion could adversely affect our supply chain and operating results."
Napco Security Technologies / 10-K / 2026-08-24
So the filing pattern has two lanes. Data center demand is being cited as a source of volume, revenue, and customer growth. It is also being cited as a reason components are tighter and more expensive. The measured shift is modest, but the vocabulary is broadening: more companies are reaching for the same demand story, and some are now describing the supply bill that comes with it.
