Non-GAAP Financial Measures
In addition to financial results reported in accordance with U.S. GAAP, PetIQ uses the following non-GAAP financial measures: Adjusted net income, adjusted net income, adjusted gross profit, adjusted gross margin, adjusted G&A, adjusted EBITDA, and adjusted EBITDA margin.
Adjusted net income consists of net income (loss) adjusted for tax expense, acquisition expenses, integration costs and costs of discontinued clinics, new clinic launch expense, non-same-store revenue, non-same-store costs, litigation costs, and stock-based compensation expense. Adjusted net income is utilized by management: to evaluate the effectiveness of our business strategies.
Adjusted gross profit consists of gross profit adjusted for gross loss on veterinarian clinics and wellness centers that are not part of same store sales. Adjusted gross profit is utilized by management to evaluate the effectiveness of our business strategies.
Adjusted G&A consists of G&A adjusted for acquisition expense, stock compensation expense, non-same store G&A, integrations expense, clinic launch expense, and litigation expense.
EBITDA and Adjusted EBITDA are non-GAAP financial measures. EBITDA represents net income (loss) before interest, income taxes and depreciation and amortization. Adjusted EBITDA represents EBITDA plus adjustments for transactions that management does not believe are representative of our core ongoing business. Adjusted EBITDA margin is adjusted EBITDA stated as a percentage of net sales. Adjusted EBITDA is utilized by management: (i) as a factor in evaluating management's performance when determining incentive compensation, (ii) to evaluate the effectiveness of our business strategies and (iii) allow for improved comparability over prior periods due to significant growth in the Company’s new wellness centers. The Company presents EBITDA because it is a necessary component for computing adjusted EBITDA.
We believe that the use of adjusted net income, adjusted gross profit, adjusted gross margin, adjusted general and administrative expenses (Adjusted G&A), adjusted EBITDA, and adjusted EBITDA margin provide additional tools for investors to use in evaluating ongoing operating results and trends. In addition, you should be aware when evaluating adjusted net income, adjusted gross profit, adjusted G&A, adjusted EBITDA and adjusted EBITDA margin, that in the future we may incur expenses similar to those excluded when calculating these measures. Our presentation of these measures should not be construed as an inference that our future results will be unaffected by these or other unusual or non-recurring items. Our computation of adjusted net income, adjusted gross profit, adjusted G&A, adjusted EBITDA and adjusted EBITDA margin may not be comparable to other similarly titled measures computed by other companies, because all companies do not calculate adjusted net income, adjusted gross profit, adjusted EBITDA and adjusted EBITDA margin in the same manner. Our management does not, and you should not, consider adjusted net income, adjusted gross profit, adjusted EBITDA margin, or adjusted EBITDA in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of adjusted net income, adjusted gross profit, adjusted EBITDA margin, and adjusted EBITDA is that they exclude significant expenses and income that are required by GAAP to be recorded in our financial statements.
