The year that was
Beside Shaw Group's big jump following the announcement that the company will be bought out by Chicago Bridge & Iron (CBI), AECOM's stock has performed the best in comparison to its peers, and has outperformed the S&P 500 by three percentage points.

If the numbers in the table don't quite add up with the stock chart, though, you're right. The reason that AECOM looks so unattractive based on net margins and ROE is because the company enacted a $300 million asset wrtiedown in the past quarter, which made its income statement look miserable. This writedown had almost nothing to do with the company's operational efficiency. If you look at the cash flow statement, you will see that AECOM has generated big chunks of cash in the past two quarters. This big cash haul has really helped the company bring down its debt below the $1 billion mark and strengthen its cash position.

Overall, AECOM had a pretty strong year. While revenue remained relatively flat at $2 billion a quarter for the past four quarters, gross margins improved from 4.4% to 6.9% over that time frame. Also, order backlog has improved by 3% per year since 2011. The company announced back in August that it will be buying back approximately $300 million in company shares, which should help to prop up share prices. With a backlog equal to about two years of revenue, the company is positioned relatively well in the event of a slowdown in construction activity.

What a Fool believes
While there are some promising numbers coming from the company, there are some macroeconomic issues surrounding the construction business that could hurt AECOM in the future. The most obvious one at this time involves the budget cuts associated with the fiscal cliff. AECOM generates 36% of its revenue from federal, state, and local government contracts, and another 25% from foreign governments. Granted, the company is relatively well-diversified geographically, but China's drawback on infrastructure spending, Europe's continued financial woes, and the likelihood of budgetary cuts in the U.S. all add up to a potential rough patch.

It may take a several quarters before any big changes happen with revenue, so to get a better gauge on AECOM's prospects, watch that order backlog. If the backlog starts to shrink, then it may be an indication of tougher times ahead.
