Ericsson (NASDAQ: ERIC) today announces the appointment of Christophe Van de Weyer as Head of

Business Area Global Communications Platform and CEO of Vonage. He will also become a member of

Ericsson’s Executive Team.

Christophe Van de Weyer joined Vonage in 2025 and has led the company’s efforts to leverage high-

performance, programmable networks and advanced communication capabilities to accelerate the

digital transformation of enterprises worldwide, with a particular focus on realizing profitable growth

in Communications Platform as a Service (CPaaS) and Network APIs.

Van de Weyer has previously held positions as CEO of Telesign globally, a US-based subsidiary of

Proximus Group, and held several senior leadership positions at Proximus. Before joining Proximus,

he spent nearly two decades at global management consulting firm Bain & Company, where he was a

partner and held various leadership roles within the firm’s Telecommunications and Technology

practice, working with the largest telcos globally.

Börje Ekholm, President and CEO of Ericsson, says: “Christophe brings a deep understanding of the

market for communication services and he has done a great job getting the Business Unit API at

Vonage back to growth. I’m happy to welcome him to the Executive Team and to accelerate the

turnaround efforts. This is another good example of a well prepared and orderly succession for critical

members of the leadership team.”

Christophe Van de Weyer says: “I’m truly excited and deeply grateful for this opportunity. Ericsson

and Vonage are at the forefront of network-powered solutions combining AI, data, and API to

transform enterprise workflows and deliver superior customer engagement. I’m looking forward to

continuing our work and further accelerating our growth momentum alongside the exceptionally

talented teams at Vonage and Ericsson.”

Niklas Heuveldop has decided to step down as Head of Business Area Global Communications Platform

and CEO of Vonage effective on August 15, 2026. He first joined Ericsson in 1993 and has served on the

Executive Team since 2016. He previously held positions such as Head of Market Area North America,

Chief Strategy Officer, Head of Technology & Emerging Business, as well as Chief Customer Officer.

Heuveldop has held his current position since February 1, 2024.

PRESS RELEASE<br><br>July 21, 2026

Börje Ekholm, President and CEO, says: “Niklas has contributed immensely to Ericsson’s turnaround

journey with his deep knowledge of our industry, outstanding customer focus, business acumen and

visionary leadership. During his tenure, Vonage has been restructured and the business refocused,

significantly strengthening its performance and restoring growth. Before that Niklas led our significant

market share expansion in North America, including the USD 14 billion network transformation deal with

AT&T. I’d like to extend my gratitude to Niklas for all his contributions to Ericsson and I wish him all the

best in his future endeavors.”

Niklas Heuveldop comments: “It has been a life changing experience to work at Ericsson for two

periods, spanning over three decades, including six overseas assignments, experiencing periods of

rapid growth, and multiple turnarounds across all business lines, globally. Ericsson is a fascinating

global powerhouse leader and it has been a true privilege to work alongside the most amazing talent in

one of the most complex and competitive industries in the world. Vonage’s turn-around continues to

gain momentum, growth has been restored, investments peaked and strategy execution is solid. We

have an exceptional team ready to continue building on our momentum, and in Christophe we have an

incredibly talented and highly appreciated leader that I’m proud to hand over the reins to. Time has

come for me to move on and pursue my next challenge.”
