Altsets estimates the KLA to Micron relationship at 4.59% of KLA revenue, 693M USD, and 2.84% of Micron COGS, showing why absolute size and relative exposure differ.

Key findings
- The KLA to Micron relationship is estimated at 4.59% of KLA revenue, 693M USD in relationship size, and 2.84% of Micron COGS.
- The 4.59% supplier revenue estimate makes Micron economically relevant to KLA even though the absolute relationship estimate is below 1B USD.
- The relationship is more concentrated in KLA's revenue base than in Micron's cost base in the displayed Altsets data.
Yes. A supplier relationship can be economically material below 1B USD when it represents a meaningful share of either company's business. Altsets estimates the KLA to Micron Technology relationship at 4.59% of KLA revenue, 693M USD in relationship size, and 2.84% of Micron cost of goods sold as of July 20, 2026.
The immediate conclusion is that the relationship is meaningful on the supplier side even though the absolute estimate is below 1B USD. Micron represents an estimated 4.59% of KLA revenue, while KLA represents a smaller 2.84% share of Micron's cost base. This is a useful example of why relationship size and relative exposure should be analyzed separately.
The relationship in one row
| Relationship | Supplier revenue | Relationship size | Customer COGS |
|---|---|---|---|
| KLA to Micron Technology | 4.59% | 693M USD | 2.84% |
The three metrics describe scale from three different perspectives. None should replace the others.
Why 693M USD can still be material
A researcher looking only at relationship size could rank a 693M USD connection below larger semiconductor relationships and stop there.
The 4.59% supplier revenue estimate changes the interpretation. It says that the mapped Micron relationship occupies a noticeable share of KLA's revenue base in the Altsets view.
That makes Micron relevant when researching KLA customer concentration, even if the absolute relationship is smaller than other equipment relationships in the same semiconductor network. This is the core analytical point: absolute dollars answer how large the relationship is, while supplier revenue percentage answers how concentrated that relationship is for the supplier.
What 2.84% of Micron COGS says from the other side
The 2.84% customer cost estimate is lower than the 4.59% supplier revenue estimate.
That does not mean KLA is operationally unimportant. Process-control equipment can be technically critical even when it represents a smaller portion of total company costs.
The percentage only describes estimated economic share. It does not measure whether Micron can substitute another inspection or metrology platform, how long qualification would take, or what production would be affected. From the relationship data alone, the safer conclusion is that Micron appears more concentrated within KLA's revenue base than KLA appears within Micron's overall cost base.
Why KLA appears upstream from a memory manufacturer
KLA describes its semiconductor process-control business as inspection, metrology, data analytics, and related services used from research and development through volume manufacturing. Its current disclosures specifically describe support for DRAM, 3D NAND, logic, and other semiconductor production.
That business context explains why KLA can be an upstream supplier to Micron. The Altsets data provides the estimated economic relationship. KLA's public materials explain the type of manufacturing role that makes the relationship plausible. The displayed relationship does not identify the exact KLA product, Micron fab, service agreement, or purchase schedule.
How this can change research priority
Suppose Micron announces a large change in memory manufacturing investment.
A researcher can use supplier revenue percentage to identify upstream companies for which Micron may be economically significant. The 4.59% KLA revenue estimate makes KLA a reasonable follow-up candidate.
Suppose instead that the event begins at KLA. Customer cost percentage can be used to identify customers with mapped cost exposure. The 2.84% Micron COGS estimate says the relationship is visible, but it should be combined with operational evidence before making a disruption conclusion. The data therefore supports both customer read-through and supplier-event triage, depending on which company the research starts with.
What the relationship does not prove
The estimates do not establish exact purchases, product mix, contract duration, current order levels, replacement difficulty, or future revenue effects.
They also do not prove that KLA is Micron's most important process-control supplier or that Micron is KLA's largest customer. Those questions require a broader defined relationship set.
The 693M USD figure should be treated as an estimated relationship size, not an audited contract value. For definitions of all three metrics and their limitations, read the Altsets supply-chain data methodology.
The useful takeaway
The KLA to Micron relationship shows why a sub-1B USD edge can still matter in supply-chain research. 4.59% of KLA revenue is large enough to make Micron economically relevant from the supplier's perspective, even though the mapped relationship represents a smaller 2.84% of Micron COGS from the customer side.
That is a different question from simply asking who supplies Micron. It asks how much one named relationship matters relative to the companies around it. Browse the Company Dependency Research collection for more quantified company relationships.
