Non-GAAP Financial Measures

Free Cash Flow:Free cash flow is a non-GAAP financial measure defined as cash flows from operations less capital expenditures. We consider free cash flow to be useful as an indicator of our overall liquidity, as the amount of free cash flow generated in any period is representative of cash that is available for strategic opportunities including, among others, investing in the Company’s business, making strategic acquisitions, strengthening the balance sheet, repaying debt, paying dividends and repurchasing stock. Free cash flow should not be construed as an alternative to cash flows from operations or other cash flow measurements determined in accordance with GAAP.

EBITDA:EBITDA is a non-GAAP financial measure defined as net income before interest, income tax expense, depreciation and amortization. We include information concerning EBITDA because we believe it is a useful measure to evaluate our operating performance. As a measure of our operating performance, we believe EBITDA provides a measure of operating results unaffected by differences in capital structures, capital investment cycles and ages of related assets among otherwise comparable companies. While EBITDA is a relevant and widely used measure of operating performance, it does not represent net income as defined by GAAP and it should not be considered as an alternative to that measure in evaluating operating performance.

Non-GAAP Gross Margin and Non-GAAP Gross Profit:Non-GAAP gross margin is a non-GAAP measure defined as non-GAAP gross profit divided by revenue. Non-GAAP gross profit is a non-GAAP measure defined as gross profit before any charges to cost of goods sold that may not be indicative of ongoing operations. We believe that non-GAAP gross profit is a useful measure to investors as an alternative method for measuring our operating performance and comparing it against prior periods’ performance.

Non-GAAP Operating Expenses:Non-GAAP operating expenses is a non-GAAP measure defined as operating expenses before any charges that may not be indicative of ongoing operations. We believe that non-GAAP operating expenses is a useful measure to investors as an alternative method for measuring our expense management and comparing it against prior periods’ performance.

Non-GAAP Net Income and Non-GAAP EPS:Non-GAAP net income and non-GAAP EPS are non-GAAP measures defined as net income and EPS, respectively, before any charges that may not be indicative of ongoing operations, or any tax impact related to those charges. We believe that non-GAAP net income and non-GAAP EPS are useful measures to investors as an alternative method for measuring our earnings performance and comparing it against prior periods’ performance.

Non-GAAP income tax provision as a percentage of non-GAAP pre-tax income: Non-GAAP income tax provision is a non-GAAP measure defined as income tax provision plus any income tax adjustments that may not be indicative of ongoing operations. We believe that non-GAAP income tax provision as a percentage of non-GAAP pre-tax income is a useful measure to investors as an alternative method for measuring our effective tax rate and comparing it against prior periods’ performance.

Non-GAAP Financial Measures

Economic Profit:Economic profit (EP) is a non-GAAP financial measure defined as net operating profit after taxes less the value of invested capital multiplied by the weighted average cost of capital, where net operating profit after taxes is defined as income from operations minus tax expense and invested capital is defined as the sum of current debt, long-term debt and equity. Management uses EP to evaluate business performance and allocate resources, and it is a component in determining management’s incentive compensation. Management believes EP provides additional perspective to investors about financial returns generated by the business and represents profit generated over and above the cost of capital used by the business to generate that profit.

Formulas

Share= Units (HDD) / TAM

ASP = Revenue / Units (HDD)

Free Cash Flow= Cash Flow from Operations – Capital Expenditures

EBITDA = Net Income (Loss) + Interest + Income Tax Expense + Depreciation and Amortization

Days Sales Outstanding (DSO)= Accounts Receivable / (Revenue / 91 days)

Days Inventory Outstanding (DIO)= Inventory / (Cost of Revenue / 91 days)

Days Payables Outstanding (DPO)= Accounts Payable / (Cost of Revenue / 91 days)

Cash Conversion Cycle= DSO + DIO – DPO

Inventory Turns= 364 days / DIO

R4Q Economic Profit = R4Q Net Operating Profit After Taxes – (Invested Capital x WACC)

• Invested Capital = Short-term debt + Current portion of long-term debt + Long-term debt + Total shareholders’ equity

• WACC⁷ = 11%

R4Q ROIC = R4Q (Net Income (Loss) + Interest Expense) / R4Q Average (Short-term debt + Current portion of long-term debt + Long-term debt + Total shareholders’ equity)

R4Q ROA= R4Q Net Income (Loss) / R4Q Average Total Assets
