AECOM’s stock is trading at a 7.4% intraday gain, driven by a blockbuster Q3 report that included record adjusted EBITDA, EPS, and backlog. The company’s guidance hike and margin expansion have ignited investor optimism, but technical indicators suggest caution ahead of key resistance levels.

Q3 Earnings and Guidance Hike Ignite Rally
AECOM’s 7.4% intraday surge is directly tied to its Q3 fiscal 2025 results, which included record adjusted EBITDA of $313 million (up 10% YoY), adjusted EPS of $1.34 (up 16% YoY), and a 17.1% segment operating margin—exceeding its long-term target. The company raised full-year guidance for the third consecutive quarter, citing a $24.6 billion backlog and $551 million year-to-date free cash flow. CEO Troy Rudd highlighted 'unprecedented visibility' in infrastructure and energy megatrends, while CFO Gaurav Kapoor emphasized strong cash flow conversion and shareholder returns. These metrics, combined with a 1.0x book-to-burn ratio in both Americas and International segments, have positioned AECOM as a beneficiary of long-term secular growth.
