AXT announces long-term InP supply agreement with Lumentum
AXT Inc of Fremont, CA, USA — which makes gallium arsenide (GaAs), indium phosphide (InP) and germanium (Ge) substrates and raw materials at plants in China — has entered into a definitive agreement with Lumentum Operations LLC of San Jose, CA, USA (which designs and makes photonic products for optical networks and lasers for industrial and consumer markets) for the supply and capacity reservation of indium phosphide wafer substrates.
AXT has agreed to reserve a minimum annual commitment of indium phosphide by Lumentum for a period beginning upon entry into the agreement, running through 31 December 2031, and to support any additional capacity that may be required.
In consideration for the reservation of the product capacity, Lumentum has agreed to pay AXT an initial deposit of $43.5m, due within 30 business days after entry into the agreement, and a second deposit of $43.5m, with the timing and terms surrounding payment to be subsequently determined during calendar year 2028.
The deposits shall be applied as shipment credits towards the purchase of the products, until such deposit is exhausted.
