Construction-linked stocks fall as hot April CPI lifts Treasury yields; AMRC drops 6.6% YTD

Sterling Infrastructure, Construction Partners, FTAI Infrastructure, MasTec and Ameresco traded lower in the May 15, 2026, afternoon session after April CPI rose 3.8% year over year, pushing the 10-year Treasury yield to 4.43% and pressuring rate-sensitive construction and housing stocks. The inflation data reinforced expectations for higher-for-longer borrowing costs. The 30-year fixed mortgage rate stood at 6.45% earlier in the week, while existing home sales growth missed analyst expectations and the median existing home price reached a record $417,700. Ameresco shares remained down 6.6% year to date at $28.64, 33.8% below their 52-week high of $43.23 set in October 2025. The stock has been volatile, with 40 moves of more than 5% over the past year. Its largest move came nine months earlier, when shares rose 39.4% after second-quarter revenue increased 8% to $472.3 million and adjusted EPS of $0.27 beat expectations.
