U.S. GENERALLY ACCEPTED ACCOUNTING PRINCIPLES (GAAP) TO NON-GAAP RECONCILIATIONS

In an effort to provide investors with additional information regarding our results as determined by GAAP, we disclose various non-GAAP financial measures in our quarterly earnings press releases and other public disclosures. The non-GAAP financial measures include: (i) adjusted gross profit, (ii) adjusted gross profit as a percentage of revenue, (iii) adjusted earnings before interest, taxes, depreciation and amortization and excluding other costs (Adjusted EBITDA), (iv) Adjusted EBITDA as a percentage of revenue, (v) adjusted net (loss) income attributable to DNOW Inc., (vi) adjusted diluted earnings per share attributable to DNOW Inc. stockholders, (vii) net debt and (viii) net debt leverage ratio. We use these non-GAAP financial measures to evaluate and manage the Company’s operations because we believe they provide useful supplemental information regarding the financial performance of our business. These non-GAAP financial measures are not intended to replace the GAAP financial measures. The Company defines Adjusted Gross profit as revenue, less cost of products, plus amortization of intangibles, plus inventory-related charges incremental to normal operations, plus transaction costs associated with acquisitions, such as inventory fair value step-up or write-downs and plus or minus the impact of our LIFO inventory costing methodology. We define Adjusted EBITDA as net (loss) income plus interest, taxes, depreciation and amortization and excluding other costs, such as stock-based compensation, restructuring and exit costs, transaction related charges, long-lived asset impairments (including goodwill and intangible assets), inventory-related charges incremental to normal operations and plus or minus the impact of our LIFO inventory costing methodology. Transaction-related charges include transaction costs, inventory fair value step-up, retention bonus accruals and integration expenses associated with acquisitions. We define Net Debt as total long-term debt, including current portion, minus cash. We define our net debt leverage ratio as Net Debt divided by trailing twelve months Adjusted EBITDA. The Company believes Net Debt is an indicator of the extent to which the Company’s outstanding debt obligations could be satisfied by cash on hand and a useful metric for investors to evaluate the Company’s leverage position. We believe the net debt leverage ratio is a commonly used metric that management and investors use to assess the borrowing capacity of the Company. A reconciliation of each of these non-GAAP financial measures to its most comparable GAAP financial measure is included in the schedules herein. Totals in the schedules herein may not foot due to rounding.
