If one stock has owned the spotlight in 2026, it is Micron (MU). Driven by booming demand for AI products, the memory chip maker’s shares have soared by nearly 720% over the past year. Earlier this month, MU even printed an all-time high of $1,089.29. For investors, it has been an enormous wealth generator — but the story doesn’t end with Micron itself.
Micron Doesn’t Run Alone — It Leans on a Supply Chain
Micron is a memory chip manufacturer, and its operations depend on a web of other companies that supply the services and raw materials it needs. Only when these partners keep the supply chain running smoothly can Micron sustain production and meet demand. That dependence means MU’s rise has quietly lifted several of its key suppliers too. Below are three publicly traded companies that could make interesting additions to your portfolio.
Axcelis Technologies (ACLS): The Earliest Link in the Chip
Axcelis Technologies (ACLS) is a semiconductor company that plays a vital role in Micron’s manufacturing supply chain. In the early stages of fabrication, Micron relies on Axcelis’s ion implantation machines — a crucial step in how its chips are made. Because of that, ACLS is closely tied to MU’s growth story. And it shows in the numbers: Axcelis Technologies (ACLS) has climbed alongside Micron, rising more than 160% in the last year.
Onto Innovation (ONTO): Keeping Quality in Check
Onto Innovation (ONTO) supplies the metrology and inspection tools that help Micron hold its standards. Micron uses Onto Innovation’s multi-wavelength Dragonfly Systems to inspect silicon wafers both during and after manufacturing. This supplier has ridden Micron’s momentum hard, with ONTO rallying over 220% across the past year.
Kulicke and Soffa (KLIC): The Backbone of Packaging and Assembly
Kulicke and Soffa (KLIC) provides assembly, packaging and manufacturing equipment to Micron. Specifically, Micron uses the company’s ball bonders, thermo-compression and vertical wire tools, and leans heavily on Kulicke and Soffa’s advanced packaging and assembly gear to keep supply flowing. Like MU, KLIC has posted solid gains, rising by about 77% over the last year.
