PLANO, Texas, March 21, 2013 /PRNewswire/ -- TGC Industries, Inc. (NASDAQ: TGE) today announced that it anticipates its 2013 first quarter to show substantial improvement over the 2012 fourth quarter.  As previously mentioned, the Company will record a reserve of approximately $2 million in the first quarter associated with clean-up expenses related to the ending of the Canadian winter season during the second quarter.  The Company did not record such a reserve in the first quarter of 2012.  Consequently, the Company is reaffirming its previously disclosed statement that it expects first quarter 2013 results to be below last year's first quarter.  This is due to the above-mentioned reserve to be taken in the 2013 first quarter that was not taken in the first quarter of 2012; land permitting delays, mainly in the Northeast; and difficult winter weather conditions in parts of the U.S. during the first two months of this year.
