FOR IMMEDIATE RELEASE

ENNIS, INC. REPORTS RESULTS

FOR THE THREE AND NINE MONTHS ENDED NOVEMBER 30, 2012

Midlothian, December 21, 2012 — Ennis, Inc. (the “Company”), (NYSE: EBF), today reported financial results for the three and nine months ended November 30, 2012.

Financial Overview

Our consolidated net sales were $129.0 million for the third quarter ended November 30, 2012 compared to $121.8 million for the third quarter ended November 30, 2011, or an increase of 5.9%. Print sales increased 17.8% for the quarter, from $69.2 million to $81.5 million. Apparel sales for the quarter declined by 9.9% (down 6.9% on units and down 3.0% on price) from $52.6 million to $47.4 million. Our consolidated gross profit margin (“margin”) decreased from 24.8% to 23.7% for the quarters ended November 30, 2011 and November 30, 2012, respectively. Our print segment margin increased from 27.8% to 28.7%, while our apparel segment margin, which continues to be impacted by higher cotton costs residing in finished goods, decreased from 20.8% to 15.2% for the quarter. As a result, our net earnings decreased from $6.9 million, or 5.7% of net sales, for the quarter ended November 30, 2011 to $6.2 million, or 4.8% of net sales, for the quarter ended November 30, 2012. Diluted earnings per share decreased from $0.27 to $0.24 for the quarters ended November 30, 2011 and November 30, 2012, respectively.

For the nine month period, net sales increased from $395.5 million to $409.9 million, or 3.6%. Print sales for the nine month period were $254.9 million, compared to $205.5 million for the same period last year, an increase of $49.4 million, or 24.0%. Apparel sales for the nine month period were $155.0 million, compared to $189.9 million for the same period last year, or a decrease of 18.4% (down 12.7% on units and down 5.7% on price). Overall our margin decreased from 26.3% to 22.6% for the nine months ended November 30, 2011 and 2012, respectively. Our print margin increased during the period from 28.4% to 29.1%, while our apparel margin decreased from 24.0% to 12.0%, again due to higher cost of cotton in finished goods. Net earnings for the period decreased from $28.0 million, or 7.1% of net sales, to $17.6 million, or 4.3% of net sales, for the nine months ended November 30, 2011 and 2012, respectively. Diluted earnings per share decreased from $1.08 to $0.68 for the nine months ended November 30, 2011 and 2012, respectively.

During the third quarter, the Company generated $13.2 million in EBITDA (a non-GAAP financial measure calculated as net earnings before interest, taxes, depreciation, and amortization) compared to $14.5 million for the comparable quarter last year. For the nine month period ended November 30, 2012, the Company generated $38.9 million of EBITDA compared to $55.3 million for the comparable period last year.

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

The Company believes the non-GAAP financial measure of EBITDA 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 is more useful in assessing management performance. In addition, EBITDA is a component of financial covenants and an interest rate metric in the Company’s credit facility.

Keith Walters, Chairman, Chief Executive Officer and President, commented by stating, “Our apparel results for the quarter continued to be impacted by the higher residual cost of cotton remaining in our finished goods inventory. As we have previously stated, we attempted to match the sale side price with the cost side in selling through this high cost inventory rather than reducing our selling price significantly below our imbedded costs and thus allowing us to take a loss in one quarter, as some of our competitors. We continue to believe this was the right approach with the overall impact associated with this over-time approach being lower than if we had taken a loss in one quarter. However, at this point, most of the higher cost cotton has made its way through our finished goods inventory and the divergence between the current purchase cost of cotton and the average cost in our finished goods inventory has returned to a closer spread. We expect to see improvement in our apparel margins in the quarters to come, absent unforeseen economic disruption. Our print gross profit margin continues to remain healthy; however, legacy selling, general and administrative costs associated with our recent acquisitions remain as we integrate these locations into our ERP systems. We believe our system conversions are going well and will provide a solid basis for lowering the overall cost structures of these plants in the future. I continue to feel positive about fiscal year 2014, especially now that our apparel division has worked through their higher cotton costs. However, I am, as most, concerned with economic discussions currently occurring in Washington D.C. and how ultimate decisions may impact next year. There remain many economic uncertainties for many businesses that our government needs to provide clarity. How will their actions or inactions impact businesses, consumers and our economy in general over the short and long term is still to play out. Nevertheless, we will continue to stay vigilant to the task at hand.”
