Print sales increased 2.7% from $97.9 million to $100.5 million and apparel sales decreased 6.9% from $54.0 million to $50.3 million. Consolidated gross profit margin (“margin”) was $40.6 million for the quarter, or 26.9%, compared to $38.2 million, or 25.1% for the same quarter last year. Print margin was 31.2% for the quarter compared to 31.1% for the same quarter last year, while apparel margin was 18.4% for the quarter compared to 14.3% for the comparable quarter last year. Apparel margin was positively impacted by improving manufacturing efficiencies and lower input costs. Net earnings for the quarter was $11.0 million, or $0.43 per diluted share as compared to $10.0 million, or $0.39 per diluted share for the same quarter last year, an increase of 10.3%.

The Company’s consolidated net sales for the six month period increased from $293.0 million to $301.3 million, or 2.8%. Print sales were $197.2 million, compared to $186.3 million for the same period last year, an increase of $10.9 million, or 5.9%. Apparel sales were $104.1 million, compared to $106.8 million for the same period last year, a decrease of $2.7 million or 2.5%. Consolidated margin increased on a dollar basis from $73.6 million to $78.2 million and increased on a percentage basis from 25.1% to 25.9% for the six months ended August 31, 2014 and 2015, respectively. Print margin increased from 30.8% to 31.1% due to continued elimination of duplicative costs associated with our recent acquisitions. Apparel margin increased from 15.1% to 16.2% due to improving manufacturing efficiencies and lower input costs during the current quarter. As a result, consolidated net earnings increased from $18.0 million, or 6.2% of net sales, for the six months ended August 31, 2014 to $20.2 million, or 6.7% of net sales, for the six months ended August 31, 2015. Diluted earnings per share increased 14.5% from $0.69 to $0.79 for the six months ended August 31, 2014 and 2015, respectively.

Non-GAAP Reconciliations

The Company believes the non-GAAP financial measure of EBITDA (EBITDA is calculated as net earnings before interest, taxes, depreciation, and amortization) provides important supplemental information to both management and investors regarding financial and business trends used in assessing its results of operations. The Company believes adding back the specified items to net earnings provides a more meaningful comparison to the corresponding reported periods and internal budgets and forecasts, provides management with a more relevant measurement of operating performance and yields metrics which are more useful in assessing management performance. In addition, EBITDA is a component of the financial covenants and an interest rate metric in the Company’s credit facility. While management believes this non-GAAP financial measure is useful in evaluating the Company’s performance, this information should be considered as supplemental in nature and not as a substitute for, or superior to, the related financial information prepared in accordance with GAAP.

During the second quarter, the Company generated $22.3 million in EBITDA compared to $20.5 million for the comparable quarter last year, or an increase of 8.8%. For the six month period ended August 31, 2015, the Company generated $41.5 million of EBITDA compared to $37.7 million for the comparable period last year, or an increase of 10.1%.

The following table reconciles EBITDA, a non-GAAP financial measure, to the most comparable GAAP measure, net earnings (dollars in thousands).

Keith Walters, Chairman, Chief Executive Officer and President, commented by stating, “Our print group’s performance continued to be solid during the quarter. Our apparel group’s performance showed significant improvement during the quarter. Improved manufacturing efficiencies and lower input costs during the quarter allowed the apparel group to show margin improvements of 410 basis points over the comparable quarter last year and 430 basis points over the most recent previous quarter. During the quarter, we started to see the benefit of lower cotton and other input costs. On the print front, we continue to be pleased with the integration of the latest acquisitions and the margins of our print group as a whole. We also continued to pay down our debt during the quarter by 26.3%, or $22.5 million, due to the effective management of our receivables and inventories. Overall, while we continue to believe fiscal year 2016 will continue to be challenging due to the overall retail and global economic environment, we continue to remain optimistic about the remainder of the year.”
