# Multinational companies headquartered in Aberdeen
Tamtam tracks 39 multinational companies headquartered in Aberdeen. This list ranks the 30 largest by number of employees on LinkedIn, led by Wood, EnerMech and First Bus. Their median headcount is 629. Half of them were founded in 1996 or later.
These are large and mid-sized companies in Aberdeen, primarily in the energy sector, with a strong emphasis on oil and gas, as well as related professional and engineering services. Companies like Wood, a global consulting and engineering firm, and EnerMech, a provider of integrated mechanical and electrical solutions, illustrate this focus. Other significant players include First Bus and FirstGroup plc in ground passenger transportation, and Johnston Carmichael Chartered Accountants, an independent financial advisory firm. Most of these companies are well-established, with many founded before 2000.
The data shows a clear concentration of companies involved in supporting the oil and gas industry. For instance, Stena Drilling specializes in drilling contracting, Sparrows Group provides lifting and handling solutions, and EnQuest is an independent oil and gas producer. Proserv focuses on energy technology solutions, while Dolphin Drilling is a harsh environment drilling contractor. This indicates Aberdeen's role as a hub for both direct energy extraction and the extensive supply chain that supports it.

## How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 11, 2026.
