Should KLA-Tencor Investors Be Worried About This New Ban on Exports to China?

In This Article:

The U.S. Commerce Department recently announced a ban on the sale of U.S. semiconductor equipment to China's state-owned Fujian Jinhua Integrated Circuit Co., a company at the heart of China's "China 2025" Plan to become a global technological powerhouse.

Fujian is alleged to have conspired to steal DRAM memory designs from U.S. memory manufacturer Micron Technology (NASDAQ: MU) and the Commerce Department wrote that "Jinhua poses a significant risk of becoming involved in activities that are contrary to the national security interests of the United States."

Last week, the U.S. Justice Department indicted both Fujian and United Microelectronics, a Taiwanese alleged co-conspirator -- as well as three individuals -- and filed suit to prevent the two companies from exporting any products that incorporate stolen designs.

That's likely to be good news for Micron, but it could potentially be problematic for the companies that supply the equipment necessary to produce memory chips. These equipment providers include KLA-Tencor (NASDAQ: KLAC), Applied Materials, and Lam Research.

KLA-Tencor reported first-quarter earnings on Oct. 29, and management touched on how the ban might affect -- or not -- its financials.

Management sees limited effect

It's perhaps no surprise that KLA-Tencor's management didn't sound any alarm bells, given the newness of the announcement. Management pointed out that the ban was related to just one specific company, Fujian, and that the ban wouldn't necessarily apply to the entire country, or to non-memory sales.

"I think we feel OK. I mean, strategically, that this situation around export control tends to be confined to that one particular situation," CFO Bren Higgins said. "... we don't think it has much effect on how we're running the business or planning for it into next year."

Last quarter, China made up 27% of KLA-Tencor's revenue, but that's distributed between native Chinese companies and multinational corporations with fabrication plants in China. KLA-Tencor also sells equipment to more than just memory manufacturers such as Fujian, also counting non-memory Chinese foundries as customers.

On the negative side, management did say that most of the 27% of Chinese revenue was made up of native Chinese companies. So if the equipment ban eventually expands to all China companies, it would affect most of that revenue.

But on the plus side, management said that most of its Chinese revenue was in foundry and logic, not memory. That's in contrast to KLA-Tencor's overall mix, which skews more toward memory, which accounted for 57% of shipments last quarter. China has long produced older-generation semiconductors, but its memory segment is relatively new.
