NON -GAAP FINANCIAL INFORMATION WE USE ADJUSTED EARNINGS BEFORE
INTEREST, TAXES, DEPRECIATION, AND AMORTIZATION (“EBITDA”) AND ADJUSTED EBITDA AS A PERCENT OF NET SALES (“ADJUSTED EBITDA MARGIN”) TO MEASURE OUR OPERATING PROFITABILITY. WE BELIEVE THAT ADJUSTED EBITDA AND ADJ USTED EBITDA
MARGIN PROVIDE MANAGEMENT, INVESTORS AND CREDITORS WITH USEFUL MEASURES OF THE OPERATIONAL RESULTS OF OUR BUSINESS AND INCREASE THE PERIOD-TO-PERIOD COMPARABILITY OF OUR OPERATING PROFITABILITY. ADJUSTED EBITDA MARGIN IS ALSO U SED IN THE
CALCULATION OF MANAGEMENT’S INCENTIVE COMPENSATION PROGRAM. THE MOST DIRECTLY COMPARABLE GAAP MEASURE TO ADJUSTED EBITDA AND ADJUSTED EBITDA MARGIN IS NET INCOME OR O PERATING PROFIT (LOSS) IN THE CASE OF OUR SEGMENTS AND NET INCOME AS A
PERCENT OF NET SALES (“NET INCOME M ARGIN”) OR OPERATING PROFIT (LOSS) AS A PERCENT OF NET SALES IN THE CASE OF OUR SEGMENTS, RESPECTIVELY. ADJUSTED EBITDA IS CALCULATED AS EARNINGS BEFORE INTEREST EXPENSE, NET, INCOME TAX EXPENSE,
AMORTIZATION OF INTANGIBLE ASSETS, DEPRECIATI ON OF PROPERTY, PLANT AND EQUIPMENT AND OTHER ADJUSTMENTS AS DEFINED BY THE SECOND AMENDED AND RESTATED CREDIT AGREEMENT DATED AS OF MARCH 29, 2019, AS AMENDED, GOVERNING OUR TERM LOANS AND REVOLVING
CREDIT FACILITY. ADJUSTED EBITDA MARGIN IS CALCULATED AS ADJUSTED EBITDA DIVIDED BY NET SALES. IN ADDITION, WE BELIEVE ADJUSTED NET INCOME, ADJUSTED BASIC EARNINGS PER SHARE ATTRIBUTABLE TO COMMON STOCKHOLDERS (“ADJUSTED BA SIC EPS”) AND
ADJUSTED DILUTED EARNINGS PER SHARE ATTRIBUTABLE TO COMMON STOCKHOLDERS (“ADJUSTED DILUTED EPS ) PROVIDE MANAGEMENT, INVESTORS AND CREDITORS WITH USEFUL MEASU RES OF OUR CORE BUSINESS PERFORMANCE AND TRENDS AND INCREASE THE PERIOD-TO-PERIOD
COMPARABILITY OF OUR RESULTS OF OPERATIONS. THE MOST DIRECTLY COMPARABLE GAAP MEASURE T O ADJUSTED NET INCOME, ADJUSTED BASIC EPS AND ADJUSTED DILUTED EPS IS NET INCOME, BASIC EARNINGS PER SHARE ATT RIBUTABLE TO COMMON STOCKHOLDERS (“BASIC
EPS”) AND DILUTED EARNI NGS PER SHARE ATTRIBUTABLE TO COMMON STOCKHOLDERS (“DILUTED EPS ), RESPECTIVELY. ADJUSTED NET INCOME IS CALCULATED AS NET INCOME EXCLUDING THE EFFECT OF CERTAIN NON-CASH, NON-RECURRING, INFREQUENT OR UNUSUAL ITEMS
SUCH AS: AMORTIZATION RELATED TO ACQUIRED INTANGIBLE ASSET S, DEPRECIATION OF THE STEPPED-UP BASIS IN PROPERTY, PLANT AND EQUIPMENT RELATED TO ACQUIRED ASSETS, STEPPED-UP BASIS IN ACQUIRED INVENTORY, STOCK-BASED COMPENSATION EXPENSE,
ACQUISITION-RELATED EXPENSES, IMPAIRMENT CHARGES, OTHER ONE-OFF ADJUSTMENTS AND THE TAX EFFECT OF THE ADJUSTMENTS. ADJUSTED BASIC EPS IS CALCULATED BY DIVIDING ADJUSTED NET INCOME BY THE WEIGHTED AVERAGE SHARES OF COMMON STOCK OUT STANDING AND
ADJUSTED DILUTED EPS IS CALCULATED BY DIVIDING ADJUSTED NET INCOME BY THE DILUTED WEIGHT ED AVERAGE SHARES OF COMMON STOCK OUTSTANDING. WE USE ADJUSTED FREE CASH FLOW TO EVALUATE THE AMOUNT OF CASH GE NERATED BY OUR BUSINESS THAT, AFTER THE CAPITAL
INVESTMENT NEEDED TO MAINTAIN AND GROW OUR BUSINESS AND CERTAIN MANDATORY DEBT SERVICE REQUIREMENTS, CAN BE USED FOR REPAYMENT OF DEBT, STOCKHOLDER DISTRIBUTIONS AND STRATEGIC OPPORTUNITIES, INCLUDING INVESTING IN OUR BUSINESS. WE BELIEVE THAT
ADJUSTED FREE CASH FLOW ENHANCES THE UNDERSTANDING OF THE CASH FLOWS OF OUR BUSINESS FOR MANAGEMENT, INVESTORS AND CREDITORS. ADJUSTED FREE CASH FLOW IS ALSO USED IN THE CALCULATION OF MANAGEMENT’S INCENTIVE COMPENSATION P ROGRAM. THE MOST
DIRECTLY COMPARABLE GAAP MEASURE TO ADJUSTED FREE CASH FLOW IS NET CASH PROVIDED BY OPERATING ACTIVITIES. ADJUSTED FREE CASH FLOW IS CALCULATED AS NET CASH PROVIDED BY OPERATING ACTIVITIES AFTER CASH USED FOR ADD ITIONS OF LONG-LIVED ASSETS.
