Littleton, Colo. (May 2, 2018) — CPI Card Group Inc. (Nasdaq: PMTS; TSX: PMTS) (“CPI Card Group” or the “Company”), a global leader in financial and EMV® chip card production and related services, today announced that Lillian Etzkorn has accepted an executive leadership position in Detroit, where she has lived for more than 40 years, in order to be closer to her home and family.

“Although it’s always a challenge to lose a member of the leadership team,” Mr. Scheirman continued, “we remain confident in our long-term opportunities. We anticipate our 2018 first quarter results will be in line with our expectations, highlighted by approximately 5% revenue growth. We will share additional information on our May 8th earnings call. We continue to focus on our strategy of deep customer focus, providing market-leading quality products and customer service, a market competitive business model, and continuous innovation.”

Non-GAAP Financial Measures

In addition to financial measures provided in this release in accordance with U.S. generally accepted accounting principles (GAAP), we have provided Adjusted EBITDA, which is a non-GAAP financial measure. Adjusted EBITDA is defined as EBITDA adjusted for litigation and related charges incurred in connection with certain patent and shareholder litigation, stock-based compensation expense, restructuring and other charges, foreign currency gain or loss, and other items that are unusual in nature, infrequently occurring or not considered part of our core operations. EBITDA represents earnings before interest, taxes, depreciation and amortization. EBITDA is presented because it is an important supplemental measure of performance, and it is frequently used by analysts, investors and other interested parties in the evaluation of companies in our industry. EBITDA is also presented and compared by analysts and investors in evaluating our ability to meet debt service obligations. EBITDA is not a measurement of financial performance under GAAP and should not be considered as an alternative to cash flow from operating activities or as a measure of liquidity or an alternative to net (loss) income as indicators of operating performance or any other measures of performance derived in accordance with GAAP. Because EBITDA is calculated before recurring cash charges, including interest expense and taxes, and is not adjusted for capital expenditures or other recurring cash requirements of the business, it should not be considered as a measure of discretionary cash available to invest in the growth of the business. Adjusted EBITDA is utilized by management in comparing our operating performance on a consistent basis between fiscal periods. We believe that these financial measures are appropriate to enhance an overall understanding of our underlying operating performance trends compared to historical and prospective periods and our peers. Management also believes that these measures are useful to investors in their analysis of our results of operations and provide improved comparability between fiscal periods.

Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information calculated in accordance with GAAP. Our definitions of EBITDA and Adjusted EBITDA may be different from similarly titled measures of other companies. We have provided below a reconciliation of Adjusted EBITDA to our GAAP net loss, which is the most directly comparable GAAP financial measure.
