Lumentum Holdings swaps US$650.4 million of convertible notes for common shares; Nvidia CEO endorses AI data center role and company commits to US optical manufacturing expansion

In early June 2026, Lumentum Holdings exchanged about US$650.4 million of its 0.50% convertible senior notes due 2028 for roughly 5 million common shares, while committing several hundred million dollars to a new US optical manufacturing facility in North Carolina.

Nvidia's CEO publicly emphasized Lumentum's role in solving AI data center connectivity bottlenecks, and Nvidia made a multiyear purchasing and US$2.0 billion investment agreement that underpins the optical capacity commitment.

The debt-for-equity swap and manufacturing expansion reshape investor perception of Lumentum's balance sheet flexibility and positioning in AI networking, though concentration risk from dependence on a small set of hyperscale customers remains a near-term risk.
