STMicroelectronics (NYSE: STM) highlights decade of custom chips for SpaceX Starlink

Rhea-AI Filing Summary

STMicroelectronics highlights a decade-long collaboration with SpaceX’s Starlink, focused on co-designing custom chips that power Starlink’s satellite broadband network. The relationship has produced billions of components for millions of user terminals and for over 10,000 Starlink satellites, including the V3 satellite, which provides more than 1 Tbps of fronthaul throughput.

Using ST’s BiCMOS technology and a new panel-level packaging process, ST has scaled to delivering over 5 million chips per day, supporting Starlink’s production of over 20,000 user terminals per day. Starlink now delivers high-speed internet to over 8 million customers in more than 150 countries. The partnership continues with a focus on next-generation satellites, phased-array antennas, and user terminals co-designed and manufactured across ST sites in France, Malta, and Malaysia.

Enclosure: A press release dated December 15, 2025, announcing STMicroelectronics and SpaceX celebrate a decade long

partnership key to Starlink global connectivity.

STMicroelectronics and SpaceX celebrate a decade-long partnership

key to Starlink global connectivity

• A decade of innovation with custom-made chips has enabled a new industry with broadband

connectivity for homes and businesses using low Earth orbit satellites.

• Starlink products are co-designed with ST engineers located in France and Italy and

manufactured in fabs located in France, Malta and Malaysia.

• ST’s BiCMOS chip technology is leveraged for Starlink high-performing phased-array antennas

delivering high-speed internet to over 8 million customers in more than 150 countries.

• Collaboration continues with a focus on ramping up ongoing designs and next-generation

satellites and user terminals.

Starbase, Texas, United States & Geneva, Switzerland – December 15, 2025 – As Starlink surpasses

8 million users of its network and terminals for home and business broadband access,

STMicroelectronics, (NYSE: STM), a global semiconductor leader serving customers across the

spectrum of electronics applications, and SpaceX celebrate ten years of collaboration driving innovation

with co-design of custom-made components for satellite communication. Over the past decade, the

collaboration has produced billions of co-designed products used in millions of Starlink user terminals in

addition to over 10,000 Starlink satellites, including Starlink’s latest V3 satellite, which provides more than

1 Tbps of fronthaul throughput.

The Starlink user terminal is the first and only consumer electronics phased array antenna, that delivers

reliable high-speed internet by connecting to thousands of Starlink satellites in low Earth orbit. Designed

for self-install, Starlink is set up with just two steps, plug it in, point at the sky. SpaceX has pioneered

high-rate manufacturing of these complex antennas while maintaining robust supply chain operations and

ensuring the timely delivery of Starlink hardware to its expanding global customer base. Today, Starlink

produces over 20,000 terminals per day for shipment to customers in more than 150 countries.  ST

products have been critical to allow SpaceX to scale production to meet the growing demand for Starlink

connectivity globally.

“Our partnership with STMicroelectronics has been instrumental in enabling the scale and performance of

Starlink. We are excited to continue this journey with ST to deliver the next generation connectivity

solutions that make high-speed internet available to more people, helping improve education, healthcare,

and business opportunities in places that never had reliable internet before” emphasized Gwynne

Shotwell, President and COO at SpaceX.

“We are proud to celebrate a decade of collaboration with SpaceX. From initial concept to high-volume

manufacturing, our close collaboration has been instrumental in realizing SpaceX’s vision and meeting

their very ambitious mission. Through co-designing key chips, providing engineering services and

delivering high-volume manufacturing, we demonstrate the exceptional value of ST’s innovation and

manufacturing capabilities. While supplying billions of products annually for Starlink user terminals, we

also contribute critical technologies to in-orbit systems onboard Starlink satellites, underscoring ST’s

longstanding expertise in space-grade applications.” said Remi El-Ouazzane, President,

Microcontrollers, Digital ICs, and RF Products Group at STMicroelectronics.

Starlink products are co-designed with ST engineers located in France and Italy, manufactured in fabs

located in France and packaged and tested in Malaysia and Malta. The collaboration has focused on

products based on BiCMOS technology, for which ST developed a new manufacturing process with

Starlink as lead customer around PLP (panel level packaging) technology to meet the very challenging

requirements in terms of volume and quality at competitive costs. The scaling of ST’s PLP operations has

already enabled a delivery run rate of over 5 million chips per day to meet the fast ramp-up of Starlink’s

operations. In addition, Starlink is also using multiple ST products including STM32, secure elements,

GNSS across its broadband satellites’ constellation, direct-to-cell satellites, ground infrastructure and

user terminals.

The collaboration continues beyond this milestone, built on the same deeply collaborative model and

focused on next-generation satellites and user terminals. It centers on advancing new generations of key

enabling technologies for phased-array antennas powered by ST’s BiCMOS-based solutions.

About Starlink

Starlink is the world’s most advanced satellite constellation in low-Earth orbit, delivering reliable
