Petco Reports First Quarter 2026 Results

Returns to Positive Comp Growth in Q1, Validating ‘Reach for the Sky’ Initiatives

Delivers Q1 Sales and Profitability Ahead of Previously Provided Outlook

Reaffirms Fiscal 2026 Outlook and Provides 2Q Outlook*

San Diego, June 3, 2026 – Petco (Nasdaq: WOOF), the retailer “where the pets go” to find everything they need to live their best lives, today reported its first quarter 2026 financial results.

“Our strong first-quarter results, highlighted by positive comparable sales and profitability that exceeded our outlook, provide clear, early validation that our Phase 3 ‘Reach for the Sky’ strategy is working. We were particularly pleased to see the improvement in our consumables business, while our differentiated services business continues to outperform and is a key engine of our growth. This solid start to the year demonstrates the power of our distinct, wholly owned omnichannel ecosystem. As we look ahead, we are pleased with the momentum our initiatives are generating, positioning us to continue to deliver positive comps. We remain highly confident in our ability to drive consistent, long-term growth,” said Joel Anderson, Chief Executive Officer of Petco.

Q1 2026 Overview

For the first quarter of 2026 compared to the first quarter of 2025:

Sabrina Simmons, Chief Financial Officer of Petco, added, “Our strong first-quarter results—which marked a return to positive comparable sales growth—demonstrate that our operational and economic improvements are materializing. We are pleased to reaffirm our full-year outlook. As our strategic initiatives continue to take hold, we continue to be focused on strengthening our retail and financial fundamentals to support sustainable, profitable growth and remain committed to reducing our leverage ratio to 2x.”1

Q1 2026 Balance Sheet and Cash Flow

2026 Outlook

The company reaffirmed its full year 2026 net sales and EBITDA outlook and provided its outlook for the second quarter of 2026.

Assumptions in the outlook include that economic conditions, currency rates and the tax and regulatory landscape remain generally consistent, and that current or planned tariffs on imports into the U.S. from China and other countries as of June 3, 2026, will remain at current levels. Additionally, our outlook assumes the benefit of a partial IEEPA tariff refund received in May 2026, with no additional refunds assumed for the balance of the year, and now assumes that fuel prices remain elevated at approximately those experienced in the first quarter for the remainder of the year, compared to our prior outlook which assumed higher fuel prices for the first quarter only.

With respect to the second quarter specifically, the benefit of the tariff refund received in May 2026 is expected to be approximately offset by incremental tariffs and higher fuel costs anticipated in the period. The prior-year second quarter included an approximately $9 million SG&A benefit from a favorable semi-annual actuarial true-up related to employee optimization work, which the Company does not expect to recur in the second quarter of 2026.

Full Year 2026 Outlook

Second Quarter 2026 Outlook

* Adjusted EBITDA is a non-GAAP financial measure and has not been reconciled to the most comparable GAAP outlook because it is not possible to do so without unreasonable efforts due to the uncertainty and potential variability of reconciling items, which are dependent on future events and often outside of management’s control and which could be significant. Because such items cannot be reasonably predicted with the level of precision required, we are unable to provide outlook for the comparable GAAP measures. Forward-looking estimates of Adjusted EBITDA are made in a manner consistent with the relevant definitions and assumptions noted herein and in our filings with the Securities and Exchange Commission.

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 this 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 this earnings release. The non-GAAP financial measures in this 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 Securities and Exchange Commission’s (SEC) rules because it excludes certain amounts included in net income calculated in accordance with GAAP. Management believes that Adjusted EBITDA is a meaningful measure to share with investors because it facilitates comparison of the current period performance with that of the comparable prior period. In addition, Adjusted EBITDA affords investors a view of what management considers to be Petco’s core operating performance 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 Annual Report on Form 10-K for the fiscal year ended January 31, 2026 filed with the SEC on March 13, 2026 for additional information on Adjusted EBITDA.

The table below reflects the calculation of Adjusted EBITDA for the thirteen weeks ended May 2, 2026 compared to the thirteen weeks ended May 3, 2025.

Free Cash Flow

Free Cash Flow is a non-GAAP financial measure that is calculated as net cash provided by operating activities 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.

The table below reflects the calculation of Free Cash Flow for the thirteen weeks ended May 2, 2026 compared to the thirteen weeks ended May 3, 2025.

Net Debt

The table below reflects the calculation for net debt as of May 2, 2026 compared to January 31, 2026 and May 3, 2025.
