Segment Data In connection with the Separation and the Acquisition, we made significant changes to our organizational management and reporting structure. As a result, we revised our reportable segments to reflect how the chief operating decision maker (the chief executive officer) (the CODM) currently reviews financial information and makes operating decisions. This resulted in a change in the operating segments from (i) supply chain, and (ii) technology and value-added services to (i) North America, (ii) Europe, and (iii) APAC &amp; Emerging Markets. While the historical business was focused on driving growth through specific product and service offerings to its customers, the Separation and the Acquisition allowed for the integration of the different products and service offerings, along with prescription management, data analytics, and insights through veterinary practice management software, into one multi-channel veterinary platform. We will focus on delivering the integrated platform of products and services to our customers on a geographical basis. During the three months ended June 30, 2019, our CODM began evaluating segment profit (loss) solely based on adjusted earnings before interest, taxes, depreciation and amortization (Adjusted EBITDA). In the prior period, our CODM was using both operating income and Adjusted EBITDA for measurement purposes, thus operating income was presented as it most closely reflected the measurement principle applied to our consolidated and combined financial statements. We do not allocate to our segments certain items managed at the corporate level. All intersegment balances and transactions have been eliminated in consolidation. The following tables reflects the segment recast for the prior-year period and reconciles Adjusted EBITDA for reportable segments to consolidated net income (loss): At and For the Three Months Ended June 30, 2019 (In millions) North America Europe APAC &amp; Emerging Markets Corporate Eliminations Total Net sales $ 552 $ 370 $ 90 $  $ (3 ) $ 1,009 Adjusted EBITDA $ 43 $ 19 $ 4 $ (13 ) $  $ 53 Total assets $ 3,265 $ 797 $ 191 $ 872 $ (935 ) $ 4,190 Reconciliation of Net Loss Attributable to Covetrus to Adjusted EBITDA: Net loss attributable to Covetrus $ (10 ) Plus: Depreciation and amortization 41 Plus: Interest expense, net 14 Plus: Income tax expense 5 Earnings before interest, taxes, depreciation, and amortization 50 Plus: Share-based compensation 10 Plus: Formation of Covetrus 6 Plus: IT infrastructure 2 Plus: Other (income) expense items (15 ) Adjusted EBITDA $ 53 At and For the Three Months Ended June 30, 2018 (In millions) North America Europe APAC &amp; Emerging Markets Corporate Eliminations Total Net sales $ 520 $ 390 $ 98 $  $ (3 ) $ 1,005 Adjusted EBITDA $ 45 $ 22 $ 5 $ (10 ) $  $ 62 Total assets $ 1,356 $ 681 $ 199 $ 14 $ (4 ) $ 2,246 Reconciliation of Net Income Attributable to Covetrus to Adjusted EBITDA: Net income attributable to Covetrus $ 29 Plus: Depreciation and amortization 16 Plus: Interest expense, net 1 Plus: Income tax expense 8 Earnings before interest, taxes, depreciation, and amortization 54 Plus: Share-based compensation 2 Plus: Restructuring costs 6 Adjusted EBITDA $ 62 For the Six Months Ended June 30, 2019 (In millions) North America Europe APAC &amp; Emerging Markets Corporate Eliminations Total Net sales $ 1,049 $ 731 $ 176 $  $ (6 ) $ 1,950 Adjusted EBITDA $ 78 $ 35 $ 8 $ (15 ) $  $ 106 Reconciliation of Net Loss Attributable to Covetrus to Adjusted EBITDA: Net loss attributable to Covetrus $ (23 ) Plus: Depreciation and amortization 71 Plus: Interest expense, net 25 Plus: Income tax expense 1 Earnings before interest, taxes, depreciation, and amortization 74 Plus: Share-based compensation 25 Plus: Formation of Covetrus 15 Plus: Carve-out operating expenses 5 Plus: IT infrastructure 2 Plus: Other (income) expense items (15 ) Adjusted EBITDA 106 For the Six Months Ended June 30, 2018 (In millions) North America Europe APAC &amp; Emerging Markets Corporate Eliminations Total Net sales $ 1,001 $ 761 $ 196 $  $ (6 ) $ 1,952 Adjusted EBITDA $ 79 $ 39 $ 10 $ (18 ) $  $ 110 Reconciliation of Net Income Attributable to Covetrus to Adjusted EBITDA: Net income attributable to Covetrus $ 51 Plus: Depreciation and amortization 33 Plus: Interest expense, net 1 Plus: Income tax expense 14 Earnings before interest, taxes, depreciation, and amortization 99 Plus: Share-based compensation 4 Plus: Restructuring costs 7 Adjusted EBITDA $ 110
