Arcos Dorados First Quarter 2026 Results   May 20, 2026

ARCOS DORADOS REPORTS FIRST QUARTER 2026 FINANCIAL RESULTS

Montevideo, Uruguay, May 20, 2026 – Arcos Dorados Holdings Inc. (NYSE: ARCO) (“Arcos Dorados” or the “Company”), Latin America and the Caribbean’s largest restaurant chain and the world’s largest independent McDonald’s franchisee, today reported unaudited results for the three months ended March 31, 2026.

Message from Luis Raganato, Chief Executive Officer

Arcos Dorados has consistently added to its leading market share position and strengthened the McDonald’s Brand across our operating footprint over the last several years. In fact, taking 2019 as the base, through the end of 2025: total revenue grew almost 60%, Adjusted EBITDA nearly doubled and net income was up more than 2.5x, in US dollars. Our objective for the coming years is to build on this incredible foundation and continue to capitalize on the significant competitive advantages we built over the period.

With that context, 2026 is off to a good start. First quarter 2026 highlights included $1.2 billion in total revenue, the Company’s highest level for a first quarter, which was supported by 16% systemwide comparable sales growth. Increased guest volume in NOLAD and SLAD added to higher average checks in Brazil and SLAD to drive growth in the period. Similar to total revenue, we generated our highest Adjusted EBITDA for a first quarter, reaching $118 million thanks to strong topline growth and very solid margin expansion, especially in Brazil and SLAD.

We are pursuing strategies that capitalize on the Brand to monetize the significant market share advantage we hold in the region. Marketing campaigns focused on offering value platforms that appeal to lower income consumers and core menu items that drive Brand love as well as licenses and partnerships that keep McDonald’s culturally relevant. The Brand experience continued to expand beyond our restaurants, bolstered by the region’s most extensive digital platform and Loyalty Program.

During the quarter, we added 19 new restaurants to our footprint and are already seeing opening costs per unit coming down thanks to more efficient capital deployment. Finally, 75% of our restaurants now offer guests the most modern experience available in the region’s quick service restaurant industry.

AD Holdings Inc. – Consolidated Key Financial Results

Figure 1

(In millions of U.S. dollars, except as noted)

Arcos Dorados’ total revenues reached $1.2 billion, up 12.9% in US dollars versus the prior year quarter. The Company’s systemwide comparable sales rose 16.0% in the quarter, underpinned by positive guest traffic trends in SLAD and NOLAD, together with average check growth in Brazil and SLAD.

Digital channel sales rose about 21% in the period and represented 64% of the first quarter’s systemwide sales. Performance remained notably strong in Self-order kiosk, Delivery and Loyalty sales versus the prior year. Self-order kiosk sales growth was helped by the increasingly modernized restaurant base. Delivery sales were helped by new partnerships in Brazil and expanding penetration in NOLAD and SLAD, where a growing number of consumers are discovering the convenience and value of the service.

The Company’s Loyalty Program is available in all main markets and grew to 30.4 million registered members as of the end of the quarter. Enrollment and engagement has grown consistently since the Program’s launch, leading to more personalized marketing capabilities and a notable increase in both usage and frequency among members.

Marketing campaigns during the quarter spanned core menu, affordability, and partnerships. In Brazil, for example, initiatives included the introduction of Best Burger, limited time offers through Economéqui and the first promotions associated with the FIFA World Cup. In NOLAD, Mexico continued to leverage affordability platforms and localized menu offerings while Panama and Costa Rica captured early results from initiatives designed to rebalance average check and guest traffic growth in those markets. Menu innovation was a key growth driver in SLAD, with food news across the beef, chicken and dessert categories. All divisions benefited from popular licenses such as Friends and Super Mario Galaxy, appealing to both kids and adults. Finally, the Brand’s cultural relevance was reinforced in Brazil, Argentina, Chile, and Colombia through music, a key consumer passion point, at the local Lollapalooza and Estéreo Picnic festivals.

Consolidated Adjusted EBITDA margin was 9.7%, up 120 basis points versus the prior year period, driven by lower Food & Paper costs and G&A expenses as a percentage of revenue as well as gains from restaurant transactions in NOLAD and SLAD. Food & Paper contributed 60 basis points to the consolidated margin gain, led by a significant improvement in Brazil as well as better results in SLAD.

Net income margin attributable to the Company was 3.0%, or 170 basis points higher versus the first quarter of 2025. The year-over-year improvement was driven by a higher Adjusted EBITDA margin, along with favorable impacts on net interest expenses and other financing results, gain from derivative instruments and foreign currency exchange results. These positive effects more than offset higher income tax expense and depreciation.

Arcos Dorados recorded earnings of $0.17 per share in the first quarter of 2026 compared to $0.07 per share in the prior year period. Total weighted average shares were 210,663,057 in both periods.

Notable Items

Included in Adjusted EBITDA: The result in the first quarter of 2026 included $5.8 million related to restaurant transactions with sub-franchisees in NOLAD and SLAD.

Excluded from Adjusted EBITDA: The result in the first quarter of 2026 excludes $1.7 million related to the reorganization and optimization plan, which was implemented in the fourth quarter of 2025 and finalized in the first quarter of 2026.

Definitions

In addition to financial measures prepared in accordance with generally accepted accounting principles (GAAP), management analyzes business trends using a variety of performance, financial and liquidity measures, which are considered non-GAAP. This press release and the accompanying tables use the following non-GAAP measures: Adjusted EBITDA, Adjusted net cash provided by operating activities, Adjusted Free Cash Flow, Constant Currency basis, Systemwide sales, and Systemwide comparable sales growth.

Adjusted EBITDA: Management uses Adjusted EBITDA to facilitate operating performance comparisons from period to period.

Adjusted EBITDA is defined as the Company’s operating income plus depreciation and amortization plus/minus the following losses/gains: gains from sale or insurance recovery of property and equipment, write-offs of long-lived assets, impairment of long-lived assets, and reorganization and optimization plan expenses.

Management believes Adjusted EBITDA facilitates company-to-company operating performance comparisons by backing out potential differences caused by variations such as capital structures (affecting net interest expense and other financing results), taxation (affecting income tax expense) and the age and book depreciation of facilities and equipment (affecting relative depreciation expense), which may vary for different companies for reasons unrelated to operating performance. Figure 5 of this earnings release includes a reconciliation of Adjusted EBITDA to Net income attributable to Arcos Dorados. For more information, please see the Adjusted EBITDA reconciliation in Note 8 – Segment and geographic information – of our financial statements filed today with the Securities and Exchange Commission (the “SEC”) on Form 6-K.

Adjusted net cash provided by operating activities and Adjusted Free Cash Flow: Management uses Adjusted net cash provided by operating activities and Adjusted Free Cash Flow as supplemental measure to facilitate the analysis of the Company’s cash generation performance and liquidity from period to period.

Adjusted net cash provided by operating activities is defined as net cash provided by (used in) operating activities plus interest paid less interest collected. Adjusted Free Cash Flow is defined as Adjusted net cash provided by operating activities less property and equipment expenditures, and purchases of restaurant businesses paid at acquisition date plus proceeds from sales of property and equipment, restaurant businesses and related advances.

Management believes Adjusted net cash provided by operating activities and Adjusted Free Cash Flow provide useful information to investors, when considered together with GAAP measures, in evaluating the Company’s ability to generate cash to fund capital expenditures and financing activities. Management evaluates these measures prior to investing and financing decisions.

Adjusted net cash provided by operating activities and Adjusted Free Cash Flow are non-GAAP financial measures and should not be considered as an alternative to net cash provided by operating activities or any other measure of financial performance or liquidity prepared in accordance with GAAP. These non-GAAP financial measures are not defined in the same manner by all companies and may not be comparable to similarly titled measures used by other companies. A reconciliation of Adjusted Free Cash Flow to net cash provided by operating activities is included in Figure 11 of this earnings release.

Constant Currency basis: refers to amounts calculated using the same exchange rate over the periods under comparison to remove the effects of currency fluctuations from this trend analysis. To better discern underlying business trends, this release uses non-GAAP financial measures that segregate year-over-year growth into two categories:

Systemwide sales: Systemwide sales represent measures for both Company-operated and sub-franchised restaurants. While sales by sub-franchisees are not recorded as revenues by the Company, management believes the information is important in understanding its financial performance because these sales are the basis on which it calculates and records sub-franchised restaurant revenues and are indicative of the financial health of its sub-franchisee base.

Systemwide comparable sales growth: this non-GAAP measure, refers to the change, on a constant currency basis, in Company-operated and sub-franchised restaurant sales in one period from a comparable period for restaurants that have been open for thirteen months or longer (year-over-year basis) including those temporarily closed. Management believes it is a key performance indicator used within the retail industry and is indicative of the success of the Company’s initiatives as well as local economic, competitive and consumer trends. Sales by sub-franchisees are not recorded as revenues by the Company.
