SAN FRANCISCO, May 21 (Reuters) - Amkor Technology ( AMKR )

is working with Advanced Micro Devices ( AMD ) on

packaging AMD's chips, Amkor ( AMKR ) said on Thursday.

Earlier this week, Amkor ( AMKR ) said it had secured 67 additional

acres of land in Arizona next to a 104-acre parcel where it is

developing a new campus where it plans to start production in

2028.

Modern data center chips such as those from AMD and Nvidia ( NVDA )

consist of multiple chips packaged together, and those

packaging steps have become a key bottleneck in chip production.

Amkor ( AMKR ) once specialized in less-complex chip packaging but is

working to move into more advanced versions of the technology,

including through a partnership with Taiwan Semiconductor

Manufacturing ( TSM ) where Amkor ( AMKR ) will use some of TSMC's technology at

a facility in Arizona to offer some of TSMC's older technologies

to joint customers.

While Amkor ( AMKR ) has previously disclosed planned work with Nvidia ( NVDA )

and Apple ( AAPL ) at the Arizona facility, Amkor ( AMKR ) CEO Kevin

Engel told Reuters that the company is also working with AMD.

"We're moving up the value chain," Engel said. "We're more

integrated with the customers, and that's really changing the

dynamic to where we can extract more value out of our services."

At an investor event on Thursday, Amkor ( AMKR ) said it expects to

have between $8.5 billion and $9.5 billion of revenue by 2028

and $11 billion in sales by 2030.

The $9 billion midpoint of the 2028 forecast was slightly

below analyst estimates of $9.1 billion, according to data from

LSEG. Amkor ( AMKR ) shares declined 2.6% after the forecast.
