NON-GAAP FINANCIAL MEASURES

The following information provides definitions and reconciliations of the non-GAAP financial measures presented in this earnings release to the most directly comparable financial measures calculated and presented in accordance with generally accepted accounting principles (GAAP). The company has provided this non-GAAP financial information, which is not calculated or presented in accordance with GAAP, as information supplemental and in addition to the financial measures presented in the earnings release that are calculated and presented in accordance with GAAP. Such non-GAAP financial measures should not be considered superior to, as a substitute for or alternative to, and should be considered in conjunction with, the GAAP financial measures presented in the earnings release. The non-GAAP financial measures in the earnings release may differ from similarly titled measures used by other companies.

Adjusted EBITDA

Adjusted EBITDA is considered a non-GAAP financial measure under the SEC’s rules because it excludes certain charges included in net income (loss) calculated in accordance with GAAP. Management believes that Adjusted EBITDA is a meaningful measure to share with investors because it best allows comparison of the current period performance with that of the comparable period. In addition, Adjusted EBITDA affords investors a view of what management considers Petco’s operating performance to be as well as the ability to make a more informed assessment of such operating performance as compared with that of the prior period.

Please see the company’s 10-K filed on April 5, 2021 for additional information on the reconciliation of Net Income (Loss) Attributable to Class A and B-1 Common Stockholders to Adjusted EBITDA. The tables below reflect the calculation of Adjusted EBITDA for the thirteen weeks and trailing twelve months ended May 1, 2021 compared to the prior year quarter and twelve-month period ended May 2, 2020, respectively.

Adjusted Net Income and Adjusted EPS

Adjusted Net Income and Adjusted diluted earnings per share attributable to Petco (Adjusted Net Income and Adjusted EPS respectively) are considered non-GAAP financial measures under the SEC’s rules because they exclude certain amounts included in the net income (loss) attributable to common stockholders and diluted earnings per share attributable to Petco calculated in accordance with GAAP (net income (loss) and EPS respectively), the most directly comparable financial measures calculated in accordance with GAAP. Management believes that Adjusted Net Income and Adjusted EPS are meaningful measures to share with investors because they best allow comparison of the current period performance with that of the comparable period. In addition, Adjusted Net Income and Adjusted EPS afford investors a view of what management considers Petco’s earnings performance to be as well as the ability to make a more informed assessment of such earnings performance with that of the prior period.

The tables below reflect the calculation of Adjusted Net Income (Loss) and Adjusted EPS for the thirteen weeks ended May 1, 2021 compared to the prior year quarter ended May 2, 2020.

Free Cash Flow

Free Cash Flow is a non-GAAP financial measure that is calculated as net cash generated by operations less cash paid for fixed assets. Management believes that Free Cash Flow, which measures the ability to generate additional cash from business operations, is an important financial measure for use in evaluating the company’s financial performance.

Although other companies report their Free Cash Flow, numerous methods exist for calculating a company’s Free Cash Flow. As a result, the method used by Petco’s management to calculate Free Cash Flow may differ from the methods used by other companies to calculate their Free Cash Flow.

The following table sets forth a reconciliation of Free Cash Flow to net cash provided by (used in) operating activities, which Petco believes to be the GAAP financial measure most directly comparable to Free Cash Flow. The table below reflects the calculation of Free Cash Flow for the thirteen weeks ended May 1, 2021 compared to the prior year quarter ended May 2, 2020.

-10-

Net Debt

Net Debt is a non-GAAP financial measure that is calculated as the sum of current and non-current debt, less cash and cash equivalents. Management considers this adjustment useful because it reduces the volatility of total debt caused by fluctuations between cash paid against the company’s revolving credit facility and cash held on hand in cash and cash equivalents.

Although other companies report their Net Debt, numerous methods exist for calculating a company’s Net Debt. As a result, the method used by Petco’s management to calculate Net Debt may differ from the methods used by other companies to calculate their Net Debt.

The following table sets forth a reconciliation of Net Debt, to total debt, which Petco believes to be the GAAP financial measure most directly comparable to Net Debt. The table below reflects the calculation of Net Debt as of the period ended May 1, 2021 compared to the prior year quarter ended May 2, 2020.
