SK hynix West Lafayette Fab: Mass Production Slips to Second Half 2029

HanmiGlobal (the Seoul-based construction management firm running the SK hynix West Lafayette project) confirmed this week that mass production of HBM4E and HBM5 is now targeted for the second half of 2029. That is a full year slip from the "second half of 2028" guidance NIST and SK hynix cited at announcement. CEO Kwak Noh-jung said it plainly at the August 27 groundbreaking: the October 2028 cleanroom completion date is the hard constraint now, not a production date.

The detail getting buried in most coverage: SK hynix's own attorneys have told the court in the active West Lafayette zoning bench trial that missing CHIPS Act construction milestones could cause the federal government to withhold up to $458 million in direct grants and up to $500 million in loans already committed. That is a live, on-record financial linkage between an active lawsuit and nearly a billion dollars in federal disbursements. Zoning plaintiffs have filed multiple motions for preliminary injunctions to halt construction. SK hynix is countering that $98 million in already-issued building permits create vested rights that make rezoning reversal moot, but if that argument fails, you have a site relocation question on a project where excavation and piling are already underway on 133 acres at Purdue Research Park.

If your contracts touch this fab's supplier ecosystem and they don't carry force majeure or delay provisions covering regulatory litigation, get someone on that before the bench trial ruling lands.
