RE: Growth profile..seasonal pattern The first quarter( January.March ) is by far their strongest quarter , with sales in excess of $41 million in both 2011 and 2012.
Some variability can be seen in Q3, with Q4 being strong both in 2011 and stated to be so this year ( same as 2011 ) even though down time for Xmas restricts work late in the year.
Longer term, there is huge growth forecasted for the pipeline industry both in Canada and the USA.
So, if Q1/13 stands true to seasonal form, the next two reporting quarters should continue the strong earnings seen in 2011.
