Guy Ellis appointed Chief Executive Officer of NCC Group

27 October 2026

NCC Group announces the appointment of Guy Ellis as Chief Executive Officer, succeeding Mike Maddison with immediate effect, and Andy Beaver as Interim Chief Financial Officer. 

Having joined NCC Group in 2021, Guy brings a unique combination of operational, commercial and financial leadership experience, together with a deep understanding of the Group’s clients, people and markets. As CFO, Guy has played a central role in strengthening the Group’s financial performance, commercial discipline and operational visibility, and in delivering the successful divestment of Escode. 

As CEO, Guy will lead the next chapter for NCC Group, building on NCC Group’s strengths and bringing expertise from across the organisation together to help clients tackle their most important cyber security challenges.  

 

Speaking about his appointment and NCC Group's Trading Update, Chris Stone, Chair, NCC Group said: 

“Over the past four and a half years, Mike and the Executive team have transformed NCC into a focused and strategically positioned cyber security business. The successful disposal of Escode, the strengthening of our balance sheet and the substantial return of capital to shareholders have created a strong platform for future growth. After delivering our planned transformation, Mike is stepping down as CEO. 

“Today's trading update demonstrates the progress that has been made, with revenue growth, significantly improved profitability and a business that is increasingly focused on delivering sustainable shareholder value. 

“As the Group moves forward, the Board concluded, following an internal and external process, that Guy is the right person to lead NCC through this next chapter. 

“Having helped shape and deliver our strategy, Guy brings a unique combination of operational, commercial and financial leadership experience, together with a deep understanding of our clients, people and markets. Since joining the Board as Chief Financial Officer in June 2023, he has played a central role in strengthening the Group’s financial performance and commercial discipline including delivering the successful divestment of Escode. 

“To support a seamless transition, Andy Beaver, currently Group Financial Director, will assume the role of Interim Chief Financial Officer. 

“On behalf of the Board, I would like to thank Mike for his vision and leadership. He leaves NCC as a stronger business with significant opportunities ahead." 

 

Guy Ellis, NCC Group CEO said:  

“With the transformation of NCC into a pure-play cyber security business now complete, our strategy is clear: deepen client relationships, expand our managed services capabilities, scale our cyber expertise and help organisations respond to an increasingly complex threat landscape.  

“We are privileged to work with many of the world's leading organisations and there is a significant opportunity to build on those relationships. As AI continues to reshape the risk landscape, the need for trusted independent cyber expertise has never been greater.  

“I want to thank all our colleagues for their commitment, hard work and focus throughout FY26.  

“Everyone at NCC is focused on the significant opportunity ahead of us as we target organic growth, recurring revenues and to drive profits through a continued margin expansion with a plan to get to mid teen EBITDA margins.”  

Following Guy’s appointment to CEO, Andy Beaver, formerly Group Finance Director, has been appointed Interim Chief Financial Officer. Andy joined NCC Group in 2019 and is a highly experienced finance leader with more than 25 years' experience across listed and international businesses.
