QUANTA SERVICES INC, QUANTA SERVICES MANAGEMENT ...

Looking back at the second half of 2011 and forward to 2012, we have never been more excited
about the momentum Quanta is experiencing in the industries we serve and the future growth
opportunities for our company. The long-anticipated electric power transmission build-out is now
here. North America’s natural gas liquid-rich shale plays and oil sands are in full development.
Long Term Evolution (LTE) and 4G wireless networks are being rolled out and broadband stimulus
projects are being deployed across the United States. Quanta is playing a lead role in all of these
advancements. We are building the infrastructure for the future, today.
In the first half of 2011, the company faced a challenging economy and a difficult regulatory
environment fraught with delays. Despite these obstacles, our business began to improve in the
second half of 2011. Throughout the year, we remained steadfast in our focus to safely execute
projects across all of our operations.
Well-Planned Management Transition
On May 19, 2011, I transitioned from chief operating officer to president and chief executive officer, while John Colson
assumed the role of Quanta’s executive chairman. John remains actively involved with the company, working with the
executive team on strategic acquisitions and investments, international expansion and customer relations. This passing
of the baton was the final step in a long-planned succession strategy and took place at a time when Quanta was solidly
positioned for immediate and future achievement. John’s foresight and leadership has set Quanta on track for many years
of continued success.
I am honored to be named to this position and will continue to build upon the foundation that has made our
organization successful. We have a strong leadership team – one that I believe to be the best in the industry. We will
leverage our strengths to maintain our market-leading position with the goal of delivering sustained profitable growth into
the future.
