The occurrence of one or more of the events or circumstances described in the section titled “Risk Factors,” alone or in combination with other events or circumstances, may materially adversely affect our business, financial condition and operating results.

| • |     | Cost overruns, inflation, delays and other risks could significantly impact our results, particularly with 
 respect to fixed-price contracts.                                                                          |
