Fun facts about LAM RESEARCH CORP

Quirks, history, and lore behind LRCX — the kind of stuff that makes a stock memorable.

1
The Basics
U.S. semiconductor equipment company · large-cap · listed on Nasdaq · headquartered in the San Francisco Bay Area.
2
The Numbers
Annual revenue roughly $15–17 billion, with operating margins that make most industrials jealous — because when chipmakers need to etch wafers, they really need to etch wafers.
3
The History
Founded in 1980, it quietly became one of the most critical links in the global chip supply chain — the kind of company that makes headlines only when governments start panicking about export controls.
4
The Secret
It doesn't make chips — it makes the machines that make chips, specializing in etch and deposition processes that carve and coat microscopic circuit patterns onto silicon wafers.
5
The Lore
Its customers include basically every major chipmaker on Earth, and its tools are so specialized that U.S. export restrictions specifically targeting its equipment caused diplomatic tremors with China.
6
The Giveaway
Its ticker rhymes with "Larcks," its name rhymes with a baby sheep doing research, and without its plasma etch systems, the world's most advanced semiconductors simply don't get made.

Watch Items from the Filing

Foundry market (54% of Q3 revenue) declined from 59% in prior quarter due to lower mature node investments; memory market strengthened with DRAM and non-volatile memory investment growth.
