O’Neil III in 2011, then to Earl “Duke” Austin in 2016. Quanta marked its twentieth year as a public company in 2018, the year its history records revenue reaching $10 billion.[20]

Later acquisitions broadened its operations, notably Blattner in 2021 and Cupertino Electric in 2024; Quanta also completed the acquisitions of Dynamic Systems and Wilson Construction in 2025.[25] [18]
