FOR THE THREE AND SIX MONTHS ENDED AUGUST 31, 2013

Apparel Segment Continues Strong Positive Movement

Midlothian, September 23, 2013 — Ennis, Inc. (the “Company”), (NYSE: EBF), today reported financial results for the three and six months ended August 31, 2013. Highlights for the quarter include:

Financial Overview

The Company’s consolidated net sales for the quarter were $135.3 million compared to $138.3 million for the same quarter last year. Print sales were down 8.2% on a comparable quarter basis, from $86.1 million to $79.0 million. Apparel sales increased 7.6% (volume up 12.7% and selling price per unit down 4.9%) for the comparable quarter, from $52.3 million to $56.3 million. Consolidated gross profit margin (“margin”) for the quarter increased 260 basis points from 24.5%, for the same quarter last year, to 27.1%. For a quarter comparison basis, print margin remained relatively stable at 30.0% plus, while apparel margin increased from 14.4% to 23.1%. Apparel margin continued to increase on both a comparable and sequential quarter basis, due to lower input costs and higher production levels. As a result, net earnings increased from $7.6 million, or 5.5% of net sales, for the quarter ended August 31, 2012 to $9.8 million, or 7.2% of net sales, for the quarter ended August 31, 2013. Diluted earnings per share increased 31.0% from $0.29 for the 2012 quarter to $0.38 for the 2013 quarter.

For the six month period, net sales decreased from $280.9 million to $273.8 million, or 2.5%. Print sales for the six month period were $160.4 million, compared to $173.4 million for the same period last year, a decrease of $13.0 million, or 7.5%. Apparel sales for the six month period were $113.4 million, compared to $107.5 million for the same period last year, or an increase of $5.9 million or 5.5% (volume up 11.6% and price down 6.1%). The consolidated margin increased from 22.1% to 26.5% for the six months ended August 31, 2012 and 2013, respectively. Print margin increased during the period from 29.3% to 29.9%, as a result of the elimination of duplicative costs associated with the integration of acquisitions. Apparel margin increased 1,110 basis points from 10.6% to 21.7% during the period, due to lower input costs and increased production levels. Net earnings increased from $11.5 million, or 4.1% of net sales, for the six months ended August 31, 2012 to $18.3 million, or 6.7% of net sales, for the six months ended August 31, 2013. Diluted earnings per share increased 59.1% from $0.44 to $0.70 for the six months ended August 31, 2012 and 2013, respectively.

During the quarter, the Company generated $19.0 million in EBITDA (a non-GAAP financial measure calculated as net earnings before interest, taxes, depreciation, and amortization) compared to $15.7 million for the comparable quarter last year. For the six month period ended August 31, 2013, the Company generated $35.9 million of EBITDA compared to $25.7 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):

Non-GAAP to GAAP Reconciliation

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 the financial covenants and an interest rate metric in the Company’s credit facility.

Keith Walters, Chairman, Chief Executive Officer and President, commented by stating, “Overall we are pleased with our results for the quarter. Our apparel results continued to improve on both a sequential and comparative basis, as lower input costs of manufacturing and raw materials are favorably impacting their operational results. We realized a 270 basis point sequential margin improvement last quarter and a 280 basis point sequential margin improvement this quarter in our apparel margins. We would expect our apparel margin to continue to improve as our operational efficiencies improve as production levels increase. While the overall apparel market continues to be challenging, both from a pricing and volume perspective, we are seeing some pricing stability in the marketplace. Our print margin continues to remain healthy improving 30 basis points sequentially and 60 basis points for the period, as we continue to integrate acquisitions. We feel positive about the quarter and the remainder of the year.”
