Why AECOM (ACM) Stock Is Trading Lower Today

What Happened?

Shares of infrastructure consulting service company AECOM (NYSE:ACM) fell 9% in the afternoon session after the stock's negative momentum continued as the company reported disappointing fourth-quarter results, which included a revenue miss, a sharp decline in profit, and a full-year financial outlook that fell short of analysts' expectations. 

While revenue saw a slight 2% increase, net income declined by 22% compared to the same period in the previous year. Cash flow presented another concern, with operating cash flow decreasing by 34% and adjusted free cash flow falling by 51%. Compounding the weaker results, AECOM also announced it was reviewing strategic alternatives for its Construction Management business, which could include a potential sale. Following the report, UBS lowered its price target on the stock, pointing to slower revenue growth as a key factor.

The shares closed the day at $113.03, down 11.1% from previous close.

What Is The Market Telling Us

AECOM’s shares are not very volatile and have only had 2 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful, although it might not be something that would fundamentally change its perception of the business.

The previous big move we wrote about was 1 day ago when the stock dropped 2.5% on the news that concerns regarding lofty artificial intelligence valuations triggered a pullback in the technology sector. 

Nvidia slid 3% ahead of its earnings report, dragging down fellow "Magnificent Seven" peers despite a major partnership announcement with Anthropic, as investors increasingly question the durability of the AI rally. Market sentiment was further dampened by Bitcoin dropping below $90,000, signaling reduced risk appetite, and growing anxiety that the Federal Reserve may pause rate cuts in December, with the implied probability of a cut falling to roughly 50%. Adding to the weakness, Home Depot shares declined following an earnings miss and a cut to its full-year outlook. This combination of continued de-risking and valuation skepticism put the S&P 500 on pace for its fourth consecutive daily decline.

AECOM is up 7.2% since the beginning of the year, but at $113.93 per share, it is still trading 15.2% below its 52-week high of $134.35 from October 2025. Investors who bought $1,000 worth of AECOM’s shares 5 years ago would now be looking at an investment worth $2,257.
