The stock is greatly underfollowed / undervalued with proven Management that has a long track record of successfully growing the company through acquisitions). E&C industry is also at a trough and likely to have a healthy growth going forward. In addition to inorganic growth, the company has been doing a fabulous job growing the company organically.
Let's wait for the pending large acquisition announcement, which is likely to be another value accretive deal.
Warrants at current price are not interesting anymore (given $7.80 exercise price + current price of $4.00 is $11.80 and $12 is the price that mgmt can redeem after ~2 weeks of trading above $12). Even with the today's bump up in price, valuation based on P/E '15 (assuming 0.88 EPS for 2014 and YOY 16% growth) is slightly lower than yesterday's valuation before the Q3 earnings. Great company with proven mgmt and proven record.
