Semtech locked up years of chip supply+2.58% — Semtech locked up years of chip supply, up 2.58 percent today on October 13 and left the price blank.

Semtech pays, and carries the risk of idle lines
Semtech pays to reserve lines in factories it does not own; Tower collects a committed customer. The filing's own risk factors concede that demand "does not develop as anticipated" or that Semtech "does not fully utilize the capacity reserved for it" 1. The wager is that interconnect demand compounds from 800G and 1.6T links today to 3.2T 1, in a market the research firm Cignal AI sees growing from $9 billion in 2024 to an estimated $37 billion in 2026 5. As of October 13, the only SEC filing carrying the agreement is Tower's Form 6-K; Semtech's latest 8-K is its August 25 earnings report 6.
Record revenue against a 112x multiple
The business is not the fight. Second-quarter revenue hit a record $341.87 million, up 32.7% year over year, and earnings per share of $0.71 beat the $0.61 consensus 7.
