Sidara Annual Report 2025

Penspen has been a proud member of Sidara since 1990 and is one of the group’s five leading firms alongside Dar, Perkins&Will, Currie & Brown, and TYLin.

2024 was a landmark year for Sidara. Just one year after launching our unified global brand, we’ve seen extraordinary progress across our network – a testament to the talent, resilience and shared purpose of our people.

Despite well-documented market turbulence around the world, Sidara reached a major milestone, surpassing $3 billion in gross revenue for the first time. This achievement reflects not only our strategic positioning in key markets, but the relentless commitment of our teams, who continue to elevate the human experience through industry-leading expertise in design, innovation and sustainability.

“At the heart of Sidara’s work is a deep commitment to pushing boundaries and delivering excellence in architecture, engineering, project management and consultancy. Our companies continue to take on the world’s most courageous and complex challenges — both large and small.” – Talal Shair, Sidara Chairman and CEO.

The report also celebrates our expanding global footprint, with new offices in Scotland, Colombia, and the Kingdom of Saudi Arabia, and highlights our recognition as Distinguished Organisation of the Year at the 2025 AMPP Annual Conference in Nashville.
