SK Hynix Just Announced Huge News for Micron Shareholders

SK Hynix says its DRAM and HBM memory chips are sold out through 2029, a disclosure that points to AI-driven memory demand running well beyond current expectations. The read-through lands on Micron (MU), which competes directly with SK Hynix (SKHY) and is expanding its own production capacity.

The valuation gap is the core of the bull case. MU trades at roughly 5x FY2027 earnings, against a historical average of 20-25x. That is a discount of 75% or more to its own norm if the multiple were to revert to the low end of that range. Interpretation: the market appears to be pricing MU as a cyclical peak-earnings story, while a sold-out supplier three years out argues the cycle may be longer than that framing assumes.

The Motley Fool article argues MU could see significant upside once investors recognize the extended AI build-out. That is the publisher's thesis, not a confirmed earnings change. Nothing in the announcement alters MU's reported numbers directly; the signal is about demand visibility across the memory industry. Interpretation: SKHY's 2029 sell-out window gives investors a concrete duration marker for HBM and DRAM demand that was previously a matter of debate.
