Regulation G – GAAP Reconciliation Appendix P-2 Non GAAP Reconciliation of Adjusted EBITDA to Sales Percentage The Company reports its financial results in accordance with U.S. generally accepted accounting principles (GAAP). However, the Company's management believes that certain non-GAAP financial measures may provide users of this financial information additional meaningful comparisons between current results and results in prior operating periods. Management believes that these non-GAAP financial measures can provide additional meaningful reflection of underlying trends of the business because they provide a comparison of historical information that excludes certain non-operational, non-recurring or intermittently recurring items that impact the overall comparability. See the table below for supplemental financial data and corresponding reconciliations to GAAP financial measures for quarterly adjusted EBITDA as a percentage of net sales. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, the Company's reported results prepared in accordance with GAAP. 15 ($ in thousands) Q1 2013 Q2 2013 Q3 2013 Q4 2013 Q1 2014 Q2 2014 Q3 2014 Q4 2014 Q1 2015 Q2 2015 Q3 2015 Net Sales $67,213 $68,317 $68,235 $65,738 $69,204 $72,080 $74,128 $70,281 $69,904 $ 70,726 $ 70,243 Operating Income (Loss) (3,530) (201) 870 (3,002) (4,713) 1,241 678 (2,169) (947) 3,243 2,810 Depreciation & Amortization 2,061 2,244 2,367 2,358 2,295 2,163 2,160 2,133 2,096 2,126 2,119 EBITDA (1,469) 2,043 3,237 (644) (2,418) 3,404 2,838 (36) 1,149 5,369 4,929 Excluded Costs Severance - 2 962 (127) 728 290 (328) (59) 571 50 372 Stock Based Compensation (Benefit) 1,596 76 33 562 1,125 408 2,423 2,443 (541) 971 (30) Loss/(Gain) on Disposal of Property - - (36) 32 - - 97 45 - - (2) Legal Settlement - - - - - - (688) - - - - Employment Tax Matter - - - (400) - - - - - - - Loss on Sub-Lease - - - 2,928 - - - - - - - National sales meeting 1,225 - - - - - - - 1,889 - - Remediation expense - - - - - - - 340 - - - Property Impairment Loss - - - - 2,914 132 - - - - - Adjusted EBITDA $ 1,352 $ 2,121 $ 4,196 $ 2,351 $ 2,349 $ 4,234 $ 4,342 $ 2,733 $ 3,068 $ 6,390 $ 5,269 Adjusted EBITDA % of Sales 2.0% 3.1% 6.1% 3.6% 3.4% 5.9% 5.9% 3.9% 4.4% 9.0% 7.5%
