Memory Report — 2026-07-01

(1) the antitrust lawsuit is now actively moving the stocks intraday on July 1, (2) SK Hynix amended its SEC/Nasdaq filing to add the litigation as a risk factor, and (3) an Investing.com/Benzinga angle on the legal precedent and market read. These are distinct from the earlier brief, which covered exports, pricing, HBM yields, and the IPO but not the lawsuit's market impact or the SEC amendment. Let me write the follow-up brief.

The memory shortage's biggest legal threat just moved from a filing to a market event, as the DRAM price-fixing suit against the big three began denting shares and forced its way into SK Hynix's IPO paperwork.

Micron fell more than 10%, Samsung dropped nearly 6%, and SK Hynix slid over 3% in Wednesday trading as investors digested a class-action antitrust lawsuit that had been simmering since it was filed June 25. The complaint, filed as Garciaguirre v. Samsung Electronics and assigned to Judge Noel Wise, invokes Section 1 of the Sherman Act and targets companies that together hold around 90% of the global DRAM market. The core allegation is now well known: that the three companies used a coordinated shift toward high-bandwidth memory, the stacked DRAM that feeds AI accelerators, as a cover to curtail production of older DDR3 and DDR4 modules. The tail the market cares about is the remedy. If plaintiffs ultimately prove coordinated supply restrictions violated antitrust law, court-ordered remedies could weaken the supply discipline that supports today's elevated memory prices.

That is exactly why this reads as near-term noise rather than a crack in the thesis. The precedent cuts toward the defendants: in 2018 a near-identical class action accused the same three makers of coordinating cuts, Judge Jeffrey S. White dismissed it in 2020, and on March 7, 2022 the Ninth Circuit affirmed, ruling the cutbacks were "more consistent with conscious parallelism" than collusion. A motion to dismiss is expected in the coming months. Micron isn't backing down either, saying it will compete vigorously, fairly and in compliance with all applicable laws, and will defend itself against these claims. Crucially for the pricing outlook, legal experts note such lawsuits typically take years to resolve, and even if price manipulation is ultimately proven, it is unlikely to alter the supply and demand dynamics of the memory market in the short term.

The more concrete fresh wrinkle lands on the SK Hynix ADR listing. SK Hynix revised its registration statement with the SEC and completed the Nasdaq listing process anew, adding only the litigation risk to its Risk Factors section, concerning the antitrust class action filed June 25. Apart from the litigation content, there were no changes from the first registration statement filed June 24. There's also a rotation angle worth flagging into July 10: SK Hynix's Nasdaq listing is stoking fears of investor rotation, with its roughly 60% HBM share potentially luring growth investors away from Micron.

Watch the motion-to-dismiss timeline and whether TrendForce's contract data flinches at all. So far the answer is no: DRAM contract prices, updated June 30, continue to rise, with manufacturers still raising quotes amid tight supply and expectations of negative production growth.
