Some of the variation is the result of weather, particularly rain and snow, which can impact the Company’s ability to perform construction services. The weather also limits our ability to bid for and perform pipeline integrity testing and routine maintenance for our utility customers’ underground systems since the systems are used for heating.  The acquisitions of Sprint and Q3C have added to the seasonality of our business.  Q3C’s primary operations are in the Midwest United States, an area usually affected by inclement weather during the first quarter.  Similarly, a significant portion of Sprint’s revenue is derived from utility customers.  In most years, utility owners obtain bids and award contracts for major maintenance, integrity and replacement work after the heating season, and the work must be completed by the following winter.  In addition, demand for new projects can be lower during the early part of the year due to clients’ internal budget cycles. As a result, we usually experience higher revenues and earnings in the third and fourth quarters of the year as compared to the first two quarters.</font></p> <p style="TEXT-INDENT: 0.5in; MARGIN: 0in 0in 0pt;"> </p> <p style="TEXT-INDENT: 0.5in; MARGIN: 0in 0in 0pt;"><font style="FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt;" size="2">We are also dependent on large construction projects which tend not to be seasonal, but can fluctuate from year to year based on general economic conditions. Because of the cyclical nature of our business, the financial results for any period may fluctuate from prior periods, and our financial condition and operating results may vary from quarter-to-quarter.</font></p> <p style="TEXT-ALIGN: center; MARGIN: 0in 0in 0pt;" align="center"> </p> <p style="TEXT-INDENT: 0.5in; MARGIN: 0in 0in 0pt;"><font style="FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt;" size="2">Our volume of business may be adversely affected by declines or delays in new projects in various geographic regions in the United States. Project schedules, in particular in connection with larger, longer-term projects, can also create fluctuations in the services provided, which may adversely affect us in a given period. The financial condition of our customers and their access to capital, variations in the margins of projects performed during any particular period, regional, national and global economic and market conditions, timing of acquisitions, the timing and magnitude of acquisition assimilation costs, interest rate fluctuations and other factors may also materially affect our periodic results. Accordingly, our operating results for any particular period may not be indicative of the results that can be expected for any other period.</font></p> <p style="MARGIN: 0in 0in 0pt;"> </p> </div>
