Sidara Annual Report 2026

Penspen has been a proud member of Sidara (formerly Dar Group) since 1990. Sidara is a global collaborative of leading specialist firms that design for people and the planet.

In 2025, Sidara surpassed USD 3.6 billion in gross revenue and has grown to more than 55,000 people across 70+ countries. But the story behind those numbers is about much more than growth.

The Annual Report explores the projects shaping communities around the world, the people driving change, the progress we’re making on sustainability priorities, and the opportunities ahead.

“What gives me greatest confidence is not the scale of our platform, but the strength of the people who power it. Their ability to innovate and deliver meaningful outcomes for clients remains the foundation of our success.” – Talal Shair, Sidara Chairman and CEO.

Penspen Impact

In the report, Penspen’s impact is recognised through a record year for Penspen, with $500 million in new contract awards — its best sales performance to date and largest-ever contracted backlog for 2026–29. Penspen was also recognised as an ADNOC Top 20 contractor by backlog contract value for the first time, alongside major projects supporting energy security across the Middle East & Africa, including the Trans Saharan Gas Pipeline feasibility study that enabled the landmark project to move towards construction.

The report also celebrates Penspen’s growing project portfolio across Europe and LATAM — from the engineering and design of Switzerland’s CO₂ transport network and hydrogen and biomethane studies for Gas Networks Ireland, to asset integrity services supporting ENGIE Mexico’s largest gas transmission and distribution networks.
