Exhibit 99.1

BURLINGTON STORES REPORTS STRONG FIRST QUARTER SALES AND EARNINGS GROWTH, WELL AHEAD OF GUIDANCE. THIS REPRESENTS THE

14TH CONSECUTIVE QUARTER OF DOUBLE DIGIT EPS GROWTH

BURLINGTON, New Jersey; May 28, 2026 — Burlington Stores, Inc. (NYSE: BURL), a nationally recognized off-price retailer of high-quality, branded apparel, footwear, accessories, and merchandise for the home at everyday low prices, today announced its results for the first quarter ended May 2, 2026.

Michael O’Sullivan, CEO, stated, “We are pleased with our strong performance in the first quarter. Adjusted EPS grew 26% versus the first quarter of last year, which represented our 14th consecutive quarter of double digit EPS growth. This track record demonstrates our ability to consistently convert sales into operating margin expansion thereby driving strong earnings flow-through.”

Mr. O’Sullivan continued, “Total sales increased 14%, while comparable store sales increased 6%, well ahead of our guidance. Adjusted EBIT Margin increased 20 basis points, again well ahead of our guidance. This operating margin expansion was driven by ahead of plan sales, higher gross margin, and leverage on supply chain expenses.”

Mr. O’Sullivan continued, “We are raising our full year Fiscal 2026 sales and earnings guidance, passing through the entire upside from the first quarter to the full year. Our updated guidance is for comp store sales to increase 2% to 4%, and for EPS growth of 13% to 16%. These numbers underscore our ability to convert incremental comp sales into very strong earnings growth.”

Outlook

For Fiscal Year 2026 (the 52-weeks ending January 30, 2027), the Company now expects:  

For the second quarter of Fiscal 2026 (the 13-weeks ending August 1, 2026), the Company expects: 

The Company has not presented a quantitative reconciliation of the forward-looking non-GAAP financial measures set out above to their most comparable GAAP financial measures because it would require the Company to create estimated ranges on a GAAP basis, which would entail unreasonable effort. Adjustments required to reconcile forward-looking non-GAAP measures cannot be predicted with reasonable certainty but may include, among others, costs related to debt amendments, loss on extinguishment of debt, and impairment charges, as well as the tax effect of such items. Some or all of those adjustments could be significant.

Note Regarding Non-GAAP Financial Measures

The foregoing discussion of the Company’s operating results includes references to Adjusted SG&A, Adjusted EBITDA, Adjusted Net Income, Adjusted Earnings per Share (or Adjusted EPS), Adjusted EBIT (or Adjusted EBIT Margin), and Adjusted Effective Tax Rate. The Company believes these supplemental measures are useful in evaluating the performance of our business and provide greater transparency into our results of operations. In particular, we believe that excluding certain items that may vary substantially in frequency and

magnitude from what we consider to be our core operating results are useful supplemental measures that assist investors and management in evaluating our ability to generate earnings and leverage sales, and to more readily compare core operating results between past and future periods.  These non-GAAP financial measures are defined and reconciled to the most comparable GAAP measures later in this document.

The following tables calculate the Company’s Adjusted Net Income, Adjusted EPS, Adjusted EBITDA, Adjusted EBIT, Adjusted SG&A and Adjusted Effective Tax Rate, all of which are considered non-GAAP financial measures. Generally, a non-GAAP financial measure is a numerical measure of a company’s performance, financial position or cash flows that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP.

Adjusted Net Income is defined as net income, exclusive of the following items, if applicable: (i) net favorable lease costs; (ii) costs related to debt amendments and inducement charges; (iii) impairment charges; (iv) amounts related to certain litigation matters; and (v) other unusual or non-recurring expenses, losses, charges or gains, all of which are tax effected to arrive at Adjusted Net Income.

Adjusted EPS is defined as Adjusted Net Income divided by the diluted weighted average shares outstanding, as defined in the table below.

Adjusted EBITDA is defined as net income, exclusive of the following items, if applicable: (i) interest expense; (ii) interest income; (iii) costs related to debt amendments and inducement charges; (iv) income tax expense; (v) depreciation and amortization; (vi) net favorable lease costs (vii) impairment charges; (viii) amounts related to certain litigation matters; and (ix) other unusual or non-recurring expenses, losses, charges or gains.

Adjusted EBIT (or Adjusted Operating Income) is defined as net income, exclusive of the following items, if applicable: (i) interest expense; (ii) interest income; (iii) costs related to debt amendments and inducement charges; (iv) income tax expense; (v) impairment charges; (vi) net favorable lease costs; (vii) amounts related to certain litigation matters; and (viii) other unusual or non-recurring expenses, losses, charges or gains.

Adjusted EBIT Margin (or Adjusted Operating Margin) is defined as Adjusted EBIT divided by net sales.

Adjusted SG&A is defined as SG&A less product sourcing costs, favorable lease costs and amounts related to certain litigation matters.

Adjusted Effective Tax Rate is defined as the GAAP effective tax rate less the tax effect of the reconciling items to arrive at Adjusted Net Income (footnote (f) in the table below).

The Company presents Adjusted Net Income, Adjusted EPS, Adjusted EBITDA, Adjusted EBIT (or Adjusted Operating Income), Adjusted EBIT Margin (or Adjusted Operating Margin), Adjusted SG&A and Adjusted Effective Tax Rate, because it believes they are useful supplemental measures in evaluating the performance of the Company’s business and provide greater transparency into the results of operations. In particular, the Company believes that excluding certain items that may vary substantially in frequency and magnitude from what the Company considers to be its core operating results are useful supplemental measures that assist in evaluating the Company’s ability to generate earnings and leverage sales, and to more readily compare core operating results between past and future periods.

The Company believes that these non-GAAP measures provide investors helpful information with respect to the Company’s operations and financial condition. Other companies in the retail industry may calculate these non-GAAP measures differently such that the Company’s calculation may not be directly comparable.

(b) Fiscal 2026 amount represents an inducement charge related to the Company's exchange of certain of the 2027 Convertible Notes during the first quarter of Fiscal 2026. Fiscal 2025 amount relates to the settlement of the 2025 Convertible Notes during the first quarter of Fiscal 2025.

(h) Adjustments for items excluded from Adjusted Net Income. These items have been described in the table above reconciling GAAP net income to Adjusted Net Income.
