Sterling Infrastructure (NASDAQ: STRL) is set to release its second-quarter financial results after the market close on Monday, with investor expectations running high following a turbulent week that saw the stock decline 9.7%. The company's shares have been volatile, swinging sharply amid broader market concerns about AI infrastructure spending.
According to FactSet, consensus estimates for second-quarter earnings per share have risen 37.3% over the past three months to $5.01. This upward revision reflects growing optimism about the company's E-Infrastructure segment, which has been a key driver of growth. However, the full-year forecast of $18.89 per share sits just 0.8% above the top end of management's guidance range of $19.05, leaving little room for disappointment.
The stock closed Friday at $596.77, up 2.8% for the day, after a dramatic week that included a 15.2% drop on Tuesday and a 17.5% surge on Thursday. The five-session trading range was 28% of the prior Friday's close, underscoring the extreme volatility. Despite the weekly decline, the S&P 500 and Nasdaq advanced 1.05% and 1.59%, respectively, as better-than-expected cloud earnings helped calm fears about AI infrastructure returns.
Sterling's shares remain up 94.9% for 2026, reflecting the market's high expectations. The company's first-quarter results were robust, with revenue climbing 92% to $825.7 million and adjusted EPS surging 120% to $3.59. Operating cash flow reached $165.6 million. CEO Joe Cutillo noted that bid and award activity in early 2026 was strong, particularly in the E-Infrastructure segment, which generated 72% of revenue with a 23.5% adjusted operating margin.
The company's backlog provides significant visibility. Signed backlog stood at $3.80 billion as of March 31, up 78% year-over-year, while combined backlog reached $5.15 billion, up 131%. Excluding the CEC acquisition, growth was still solid at 51% and 46%, respectively. The pipeline, including expected future phases, was approximately $6.50 billion. Investors will be looking for confirmation that organic demand is accelerating, not just acquisition-driven growth.
Analysts will scrutinize three key areas in Monday's report: whether E-Infrastructure margins hold near 23.5%, whether ex-CEC backlog continues to grow, and whether management raises its full-year EPS guidance of $18.40 to $19.05. A strong beat could reinforce the upgraded forecasts, while unchanged guidance would narrow the margin for error.
Risks remain, including a 42% decline in adjusted operating income at Building Solutions during Q1, as management expects challenging housing conditions to persist through 2026. Any setbacks in data-center projects, CEC integration, or margin compression could impact backlog conversion and future earnings.
Valuation-wise, Sterling trades at 53.3 times trailing earnings, below Quanta Services' 76.4 times but above Comfort Systems' 42.6 times and EMCOR's 24.8 times. On forward estimates, the P/E drops to 31.6 times for 2026 and 24.8 times for 2027, implying earnings growth of around 27% next year. The market will be watching to see if the company can deliver on those expectations.
