Unless otherwise indicated, this financial overview is for the continuing operations of the Company, which are comprised of the production and sale of business forms and other business products, and excludes the discontinued operations comprised of the former Alstyle apparel segment. The combined operating results of the Company’s continued and discontinued operations for the three and nine months ended November 30, 2016 and the comparative periods for 2015 are set forth on the unaudited condensed financial information included in the tables below. Reconciliations and discussions of the use of the non-GAAP financial measures reported by the Company also are set forth below.

Financial Overview

Continuing Operations

The Company’s net sales for the third quarter ended November 30, 2016 were $88.7 million compared to $97.5 million for the same quarter last year, a decrease of 9.0%. Gross profit margin was $25.3 million, or 28.5%, as compared to 29.6% for the sequential quarter and 30.5% for the same quarter last year. Diluted earnings per share were $0.22, compared to $0.33 for the same quarter last year. Operational results were impacted by a $2.0 million charge for increased medical expenses incurred during the quarter. Excluding this charge, on a non-GAAP basis, for the quarter adjusted gross profit margin would have been 30.1% ($26.6 million), adjusted net earnings would have been $7.0 million and adjusted diluted earnings per share would have been $0.27.

The Company’s net sales for the nine month period ended November 30, 2016 were $270.3 million compared to $294.7 million for the same period last year, a decrease of 8.3%. Gross profit margin was $79.0 million, or 29.2%, as compared to $91.0 million, or 30.9% for the same period last year. Diluted earnings per share for the nine month period were $0.74, compared to $1.05 for last year’s comparable period. Operational results for the period were impacted by the Folder Express relocation of $2.7 million, incurred prior to the quarter, and the aggregate increased medical expenses of $4.3 million incurred during current and previous quarters. Excluding these charges, on a non-GAAP basis, for the nine months adjusted gross profit margin would have been 31.4% ($84.9 million), adjusted net earnings would have been $23.6 million and adjusted diluted earnings per share would have been $0.91.

During the third quarter, the Company generated EBITDA (a non-GAAP financial measure) of $12.4 million compared to $16.8 million for the comparable quarter last year. For the nine month period ended November 30, 2016, the Company generated $40.3 million of EBITDA compared to $52.0 million for the comparable period last year. Excluding both the impact of the Folder Express relocation and the aggregate increased medical expenses, on a non-GAAP basis, the Company generated adjusted EBITDA of $14.4 million, or 16.2% of sales for the three months and $47.3 million, or 17.5% of sales for the nine months ended November 30, 2016.

Combined Continued and Discontinued Operations

Earnings from the Alstyle apparel discontinued operations during the nine month period were $0.10, compared to $0.15 for the same period last year. The combined results for continued and discontinued operations for the nine months were $0.84 per diluted share compared to $1.20 for the same period in 2015. The net loss resulting from the sale of the apparel operations, net of tax, was $26.0 million, or a loss of $1.01 per share, which included the write-off of $16.0 million for foreign currency translation adjustments, or $10.3 million, net of taxes. As a result, on a combined basis, for the nine month period the Company’s continuing and discontinued operations realized a net loss of $4.4 million, or a loss of $0.17 per diluted share compared to net earnings of $30.9 million, or $1.20 per diluted share for 2016 and 2015, respectively.

Non-GAAP Reconciliations

To provide important supplemental information to both management and investors regarding financial and business trends used in assessing its results of operations, the Company has reported for continuing operations adjusted gross profit margin, adjusted net earnings and adjusted diluted earnings per share, each of which is a non-GAAP financial measure and each of which excludes the impact of the additional medical charges and the Folder Express relocation expense. To provide additional transparency, the Company also has included the non-GAAP financial measures of EBITDA (EBITDA is calculated as net earnings from continuing operations before interest, taxes, depreciation, and amortization), as well as adjusted EBITDA which further excludes the impact of the additional medical charges and the Folder Express relocation expense.

Management believes that these non-GAAP financial measures provide useful information to investors as a supplement to reported GAAP financial information for continued operations. Management reviews these non-GAAP financial measures on a regular basis and uses them to evaluate and manage the performance of the Company’s continuing operations. These non-GAAP financial measures provide useful information in evaluating the Company’s period-to-period performance because they eliminate certain items that the Company does not consider to be indicative of earnings from ongoing operating activities. Management believes that excluding such items provides a better understanding of the underlying trends in the Company’s operating performance and allows more accurate comparisons of the Company’s operating results for its continued operations to historical performance. In addition, EBITDA is a component of the financial covenants and an interest rate metric in the Company’s credit facility.

Reconciliations of these non-GAAP financial measures to the most directly comparable measures calculated and presented in accordance with GAAP are set out in the following tables. Other companies may calculate non-GAAP adjusted financial measures differently than the Company, limiting the usefulness of the non-GAAP measures for comparison with other companies. While management believes these non-GAAP financial measures are useful in evaluating Ennis, this information should be considered as supplemental in nature and not as a substitute or an alternative for, or superior to, the related financial information prepared in accordance with GAAP. These measures should be evaluated only in conjunction with the Company’s comparable GAAP financial measures.

The following table reconciles (1) EBITDA from continuing operations, a non-GAAP financial measure, and (2) adjusted EBITDA from continuing operations, a non-GAAP financial measure, to the most comparable GAAP measure, net earnings from continuing operations (dollars in thousands).

The following table reconciles the reported numbers to the adjusted numbers for the three and nine months ended November 30, 2016 and 2015 after the elimination of the impact associated with the additional medical charges and the Folder Express relocation expense.

Mr. Keith Walters, CEO of Ennis, stated, “While overall the quarter did not meet our expectations, we are pleased to report that the Folder Express operation no longer has a negative impact on our operational results. Although this operation has come a long way over the past nine months, we continue to focus on returning it to the contribution levels we believe are achievable for this business unit. As we experienced in the second quarter, operational results for the quarter continued to be impacted by medical claims. As a result, we expensed an additional $2.0 million to our medical reserve. To mitigate against further medical charges, we are implementing a new cost reimbursement program for our health plan as of the start of the new calendar year. However, while all indications are that this program should reduce our medical claims expense consistent with historical levels, actual cost savings may vary from anticipated levels. Generally, the print market continues to be fairly soft with competitive pricing, resulting in downward pressure on operating margins. Our balance sheet remains strong with a debt ratio, net of cash, of negative .07%. Our strong balance sheet supports our ability to pursue potential acquisition opportunities as they present themselves as we look to increasing the leverage of our corporate structure. Also, our cash position and operational cash flow provides us the flexibility to continue to repurchase

common stock under our existing stock repurchase program as we may determine is in the Company’s and our shareholders’ best interest. We repurchased 387,352 shares of our common stock during the third quarter at an average price of $15.41, with repurchases over the last six months totaling 491,057 shares. The transition services we agreed to provide to the buyer of our former apparel business segment, Alstyle, will be concluding shortly, which should allow us to reduce related redundant costs. While market conditions continue to be challenging, we believe we are well positioned to not only provide quality products, but also products that are competitively priced.”
