What Happened

Sterling Infrastructure was upgraded to Buy by Seeking Alpha, citing a significant price correction and robust revenue growth. The company reported a record backlog of $4.33 billion, demonstrating strong demand for its E-Infrastructure services.

These developments have rekindled interest in the stock, which had previously been viewed as a Hold due to valuation concerns. The recent upgrade and positive fundamentals have positioned STRL as a compelling buy for investors seeking growth in the infrastructure sector.
