April 28, 2021

Dear Fellow Shareholders,

This afternoon, following yesterday’s public filing of the registration statement and preliminary proxy statement in connection with our proposed transaction with Just Eat Takeaway.com (JET), we reported our first quarter results. Consistent with recent quarters, we are not planning to hold an earnings conference call.

Grubhub and JET remain on track to complete the transaction in the coming months. As a reminder, all required regulatory approvals for the proposed transaction have been obtained and JET’s shareholders voted overwhelmingly in favor of the proposed transaction. The registration statement and preliminary proxy statement were publicly filed with the SEC on April 27, 2021, and the Grubhub special stockholder meeting to approve the transaction and related matters as described in the preliminary proxy statement is expected to take place in June. Subject to the satisfaction of customary closing conditions, we anticipate closing the transaction shortly following the Grubhub special stockholder meeting.

Given the aforementioned timing, this is likely our last publicly reported quarter as a standalone company. And it is a perfect ending to our 18-year run as an independent company (23 if you count Seamless’ early years). We have incredibly strong momentum heading into our combination with JET. Not only did we post records in all of our key business metrics during the first quarter, our growth accelerated meaningfully from the fourth quarter of 2020. Even after adjusting for the initial decrease in orders we observed last March following the onset of COVID-19, our underlying year-over-year order growth accelerated in the high-single digits compared to our year-over-year growth in the fourth quarter of 2020. We generated 745,700 Daily Average Grubs (DAGs) (+44% year-over-year), resulting in $2.6 billion in Gross Food Sales (GFS) (+60% year-over-year) – a $10+ billion annual run-rate of local restaurant orders.

We ended the quarter with 33.0 million Active Diners (+38% year-over-year), net revenues of $550.6 million (+52% year-over-year) and negative Adjusted EBITDA of $9.3 million. Without the impact from the temporary fee caps, Adjusted EBITDA per order would have been approximately $0.80. Adjusted EBITDA was also impacted by increased delivery driver costs due to a number of transient factors during the quarter including short-term driver supply imbalances from surging demand, extreme winter weather in numerous parts of the country and, to a lesser degree, the issuance of Economic Impact Payments (i.e., stimulus payments) caused some drivers to temporarily reduce hours in March.

Grubhub also continued to support the communities in which we operate by working closely with various organizations including World Central Kitchen, Feed the Soul Foundation, NYC Restaurant Week To Go and dineL.A. Restaurant Week. We also awarded hundreds of thousands of dollars via our Driver Grant Program in support of our drivers’ local philanthropic, business or educational efforts. Finally, in the first quarter alone, we effectively conveyed more than $60 million to local restaurants across the country through COVID-related, temporary fee caps. That said, we continue to believe fee caps, which have recently started to expire in some jurisdictions, are neither an efficient nor the right way to support the long-term sustainability of restaurants.

We are extremely pleased with our record setting DAGs and GFS and our consistent underlying Adjusted EBITDA profitability ex-fee caps. We are excited about the momentum behind our hybrid marketplace as we get closer to a post-COVID environment and prepare to become part of the Just Eat Takeaway.com family.

Business Performance

Ordering Trends

We observed very robust ordering on our marketplace during the first quarter with DAGs of 745,700, an increase of 44% year-over-year (versus 31% year-over-year growth in the fourth quarter 2020) and GFS of $2.6 billion, an increase of 60% year-over-year (versus 52% year-over-year growth in the fourth quarter 2020). Even when accounting for the initial negative impact of COVID-19 we experienced in the last two weeks of March 2020, we saw a high-single digit acceleration in year-over-year order growth during the first quarter 2021 versus the fourth quarter 2020. Our singular focus on connecting diners with the best local restaurants and our consistent price leadership while maintaining similar delivery times with our logistics-oriented peers has increased diner retention and order frequency.

The strongest order growth during the quarter came from our Tier 2 and Tier 3 markets, which are primarily suburbs and smaller communities, where competition also tends to be most intense. Our sustained growth and profitability in Tier 2 and Tier 3 markets further proves that the viability of our hybrid business model is not limited to dense urban areas, but that we can be successful in driving both revenues and profits regardless of a market’s size, our Grubhub delivered versus restaurant delivered mix and/or our relative competitive position.

In Manhattan, the recovery continued with another sequential increase in DAGs in the first quarter 2021. DAGs have increased sequentially each quarter since the onset of the pandemic and were up nearly 50% in March 2021 compared to April 2020. We expect ordering activity in Manhattan to improve further, for consumers and corporate alike, as people keep returning to pre-COVID life.

Diner Acquisition and Behavior

We finished the quarter with 33.0 million Active Diners, up 38% year-over-year and a sequential increase of 1.5 million diners. New diner additions remained elevated with Tier 2 and Tier 3 markets and suburbs of Tier 1 markets accounting for the majority of our new diners. Of note, our diner behavior remains strong, with new diner repeat rates and existing diner ordering frequency still well above pre-COVID levels.

Restaurant Network

Grubhub now features over 280,000 partnered restaurants on its platform, a net increase of over 15,000 from February. Additions were relatively balanced across our three market tiers and the vast majority of new restaurant additions continue to be local businesses or small/regional chains. Even as indoor dining capacity increases throughout the country, our continued strong restaurant additions demonstrates that restaurateurs see the value in partnering with Grubhub to generate incremental orders from our marketplace to complement their dine-in business.

Use of Non-GAAP Financial Measures

Adjusted EBITDA, non-GAAP net income (loss) and non-GAAP net income (loss) per diluted share attributable to common stockholders are financial measures that are not calculated in accordance with accounting principles generally accepted in the United States, or GAAP.

We define Adjusted EBITDA as net income (loss) adjusted to exclude merger, acquisition, restructuring and certain legal costs, income taxes, net interest expense, depreciation and amortization and stock-based compensation expense. Non-GAAP net income (loss) and non-GAAP net income (loss) per diluted share attributable to common stockholders exclude merger, acquisition, restructuring and certain legal costs, amortization of acquired intangible assets, stock-based compensation expense and other nonrecurring items as well as the income tax effects of these non-GAAP adjustments. We use these non-GAAP financial measures as key performance measures because we believe they facilitate operating performance comparisons from period to period by excluding potential differences primarily caused by variations in capital structures, tax positions, the impact of acquisitions, restructuring and certain legal costs, the impact of depreciation and amortization expense on our fixed assets and the impact of stock-based compensation expense. Adjusted EBITDA, non-GAAP net income (loss) and non-GAAP net income (loss) per diluted share attributable to common stockholders are not measurements of our financial performance under GAAP and should not be considered as an alternative to performance measures derived in accordance with GAAP.

See “Non-GAAP Financial Measures Reconciliation” below for a reconciliation of net income (loss) to Adjusted EBITDA, non-GAAP net income (loss) and non-GAAP net income (loss) per diluted share attributable to common stockholders.
