Company Provides Fiscal-Year 2021 Outlook

Boston, MA - August 10, 2021: Flywire Corporation (Nasdaq: FLYW) (“the Company”) a global payments enablement and software company, today reported financial results for its second quarter of 2021.

“I am pleased to report that we generated strong second quarter results, our first in our journey as a publicly traded company,” said Mike Massaro, CEO of Flywire. “We believe our performance, as highlighted by our revenue growth, continues to demonstrate the demand for digital payments solutions and our ability to help our clients get paid and help their customers pay with ease from anywhere in the world. Additionally, in Q2 we saw positive growth trends with new client acquisition across our key verticals of education, healthcare, travel and B2B, as well as increased adoption of our solutions with current clients.”

Second Quarter 2021 Financial Highlights:

GAAP Results

• Revenue increased 56% to $37.0 million in the second quarter of 2021, compared to $23.8 million in the second quarter of 2020.

• Gross margin increased 11.6% in absolute terms to 60.8% in the second quarter of 2021, compared to 49.2%in the second quarter of 2020.

• Net loss was $18.1 million in the second quarter of 2021, compared to $16.0 million in the second quarter of 2020. The increase in the Company’s net loss was primarily due to the revaluation of our preferred stock warrants resulting in a non-cash charge of $9.8 million during the second quarter of 2021 due to the initial public offering in May 2021.

Key Operating Metrics and Non-GAAP Results

• Total Payment Volume increased 85% to $1.9 billion in the second quarter of 2021, compared to $1.0 billion in the second quarter of 2020.

• Revenue Less Ancillary Services increased 77% to $33.0 million in the second quarter of 2021, compared to $18.6 million in the second quarter of 2020.

• Adjusted Gross Margin increased 5.3% in absolute terms to 68.2% in the second quarter of 2021, compared to 62.9% in the second quarter of 2020.

• Adjusted EBITDA was $(0.1) in the second quarter of 2021, compared to $(7.0) million in the second quarter of 2020.

Fiscal-Year 2021 Outlook:

Based on information available as of August 10, 2021, for fiscal year 2021 Flywire expects the following:

• Revenue of $173 to $178 million

• Revenue Less Ancillary Services of $158 to $161 million

• Adjusted EBITDA of $4 to $6 million*

*Flywire has not provided a quantitative reconciliation of forecasted Adjusted EBITDA to forecasted GAAP net income (loss) or to forecasted GAAP income (loss) before income taxes within this earnings release because the company is unable, without making unreasonable efforts, to calculate certain reconciling items with confidence. These items include but are not limited to income taxes which are directly impacted by unpredictable fluctuations in the market price of the company’s stock.

Conference Call

The Company will host a conference call to discuss second quarter 2021 financial results today at 5:00 pm ET. Hosting the call will be Mike Massaro, CEO, Rob Orgel, President and COO and Mike Ellis, CFO. The conference call can be accessed live via webcast from the Company’s investor relations website at https://ir.flywire.com/. A replay will be available on the investor relations website following the call.

Key Operating Metrics and Non-GAAP Financial Measures table

We use non-GAAP financial measures to supplement financial information presented on a GAAP basis. We believe that excluding certain items from our GAAP results allows management to better understand our consolidated financial performance from period to period and better project our future consolidated financial performance as forecasts are developed at a level of detail different from that used to prepare GAAP-based financial measures. Moreover, we believe these non-GAAP financial measures provide our stakeholders with useful information to help them evaluate our operating results by facilitating an enhanced understanding of our operating performance and enabling them to make more meaningful period to period comparisons. There are limitations to the use of the non-GAAP financial measures presented here. Our non-GAAP financial measures may not be comparable to similarly titled measures of other companies. Other companies, including companies in our industry, may calculate non-GAAP financial measures differently than we do, limiting the usefulness of those measures for comparative purposes.

We use supplemental measures of our performance which are derived from our consolidated financial information, but which are not presented in our consolidated financial statements prepared in accordance with GAAP. These non-GAAP financial measures include the following:

• Revenue Less Ancillary Services. Revenue Less Ancillary Services represents our consolidated revenue in accordance with GAAP after excluding (i) pass-through cost for printing and mailing services and (ii) marketing fees. We exclude these amounts to arrive at this supplemental non-GAAP financial measure as we view these services as ancillary to the primary services we provide to our clients.

• Adjusted Gross Margin. Adjusted gross margin represents adjusted gross profit divided by Revenue Less Ancillary Services. Adjusted gross profit represents Revenue Less Ancillary Services less cost of revenue adjusted to (i) exclude pass-through cost for printing services and (ii) offset marketing fees against costs incurred. Management believes this presentation supplements the GAAP presentation of gross margin with a useful measure of the gross margin of our payment-related services, which are the primary services we provide to our clients.

• Adjusted EBITDA. Adjusted EBITDA represents EBITDA further adjusted by excluding (i) stock-based compensation expense, (ii) the impact from the change in fair value measurement for contingent consideration associated with acquisitions, (iii) the impact from the change in fair value measurement of our preferred stock warrants, (iv) other income (expense), net, (v) acquisition related transaction costs, and (vi) employee retention costs, such as incentive compensation, associated with acquisition activities. Management believes that the exclusion of these amounts to calculate Adjusted EBITDA provides useful measures for period-to-period comparisons of our business.

These non-GAAP financial measures are not meant to be considered as indicators of performance in isolation from or as a substitute for revenue, gross margin or net loss prepared in accordance with GAAP and should be read only in conjunction with financial information presented on a GAAP basis. Reconciliations of Revenue Less Ancillary Services, Adjusted Gross Margin and Adjusted EBITDA to the most directly comparable GAAP financial measure are presented below. We encourage you to review these reconciliations in conjunction with the presentation of the non-GAAP financial measures for each of the periods presented . In future fiscal periods, we may exclude such items and may incur income and expenses similar to these excluded items. We have not provided a quantitative reconciliation of forecasted Adjusted EBITDA to forecasted

GAAP net income (loss) or to forecasted GAAP income (loss) before income taxes within this earnings release because the company is unable, without making unreasonable efforts, to calculate certain reconciling items with confidence. These items include but are not limited to income taxes which are directly impacted by unpredictable fluctuations in the market price of the company’s stock.
