To Our Shareholders

Continued momentum

We had another strong quarter delivering for our customers with high quality

and high velocity. Square GPV growth accelerated to 12% and we gained profitable market share through product innovation and expanded distribution. T1Cash App gross profit growth accelerated to 24%, and in September we hit 58 million Cash App

monthly actives.1 Proto generated its first revenue, seeding what we believe will become our next major ecosystem. Last quarter, I outlined Cash App’s strategy to become

the financial platform for the next generation.2 This quarter, I want to outline how Square will continue to take market share by being the best platform to help sellers grow,

run, and automate their businesses.

Square powers the neighborhood

Square works for everyone, from the corner store to the national chain. We

believe we are the only company that designs the hardware, operating system, software, commerce capabilities, and financial tools for sellers. That vertical integration lets us move fast, serve more customers, and ultimately give them time back. Our

ability to do this stems from our obsession with simplicity. We built for self-service from day one and that foundation powers our scale as we move upmarket and expand internationally. Our strategy is to enable the success of sellers in their

neighborhoods. We are:

● T2Connecting Square and Cash App to deliver more value to our sellers, their employees, and their customers

● Delivering AI tools so more

sellers can put their operations and finances on autopilot

● Making selling easier with

software solutions and commerce tools for our sellers

● Meaningfully scaling our go-to-market efforts to serve every seller that wants to work with us

Connecting our ecosystems

At Square Releases last month, we introduced Neighborhoods on Cash App. We set out to give every neighborhood business access to an enterprise-quality

mobile app. For sellers, it’s everything they’d want in a mobile app, without the complexity of maintaining it across multiple platforms. For customers, it’s a seamless way to support local businesses while enjoying the same

convenience they’ve come to expect from the biggest brands.

1 A transacting active is a Cash App account that has at least one financial transaction using any product or service within Cash App during a specified period. A transacting

active for a specific Cash App product has at least one financial transaction using that product during the specified period and is referred to as an active. Examples of transactions include sending or receiving a peer-to-peer payment, transferring money into or out of Cash App, making a purchase using Cash App Card, earning a dividend on a stock investment, and paying back a loan, among others. Certain of these

accounts may share an alias identifier with one or more other transacting active accounts. This could represent, among other things, one customer with multiple accounts or multiple customers sharing one alias identifier (for example, families).

2 Square and Cash App are financial services platforms, not banks. Throughout this

letter, any reference to Square or Cash App’s banking offerings such as “bank our base,” “banking offerings,” “banking products,” “banking functionality,” or “Square Banking” refer to

products and services that are offered through Block’s Industrial Bank, Square Financial Services, Inc., or through our third-party bank partners.

For neighborhoods, it’s a powerful step toward preserving the culture, resilience, and

vibrancy that make them thrive. And because it’s built on Block’s ecosystem, it gives sellers benefits that only we can deliver:

●

A base of 58 million monthly actives in Cash App that sellers can connect with and offer

customizable rewards, tied to free marketing and discovery tools that let local sellers build stronger connections with followers through messages and campaigns right on Cash App

●

Network-wide rewards designed to drive repeat visits and attract new customers that can be redeemed with

any seller in the network to keep money local

●

Stored balances from over $300 billion that flowed into Cash App over the past year, driving our

ability to offer a 1% payment processing rate for all in-app orders8

Shipping faster and reinventing the interface with AI

Our vertically integrated platform allows us to move quickly, and we believe it gives us unique advantages in launching AI tools for sellers. T3Our

engineering team has been on the frontier of AI development for years, building internal tools like codename goose to ship features faster, reinvent the interface for our sellers, and pioneer new underwriting methodologies to expand access to our

credit products. Now, we’re using these tools to help make our sellers more successful.

Today, Square AI enables sellers to easily explore

their data to uncover even more complex insights. Soon, it will proactively suggest actions to optimize growth or improve efficiency and implement them with a tap. We expect the AI tools we build will be available to all our sellers across our

product tiers to help every seller in the neighborhood grow and run their business better. Square changed how sellers reach customers and grow by creating simple, intuitive tools. We’re doing it again with AI.

Helping sellers grow and run their business

We’re continuing to build new products and features in our core commerce platform to drive value to sellers. We’ve enhanced our financial

tools, empowering sellers to make informed choices about vendors and pricing. Our Payroll product now provides same-day payroll, and we’re testing daily tip distribution so workers get paid faster.

Over the past year, we’ve focused on winning the quick-serve restaurant (QSR) industry. We launched products including Multichannel Menus,

Kiosk, AI Voice Ordering, and Order Guide to help these sellers grow and streamline their operations. At the same time, we scaled field sales to reach bigger QSR customers. Our approach has worked. Food and beverage GPV growth accelerated to 17% in

Q3 2025 from 10% a year ago, and food and beverage new volume added (NVA) accelerated to 30% from 2% over that same time period.9 We believe the results we’ve seen can be

adapted and repeated across other verticals and international markets.

We’re also connecting our ecosystems through Square bitcoin to help

sellers grow and never miss a sale because of how their customer wants to pay. T4Square bitcoin is the first fully integrated bitcoin payments and wallet solution for businesses that will enable sellers to accept bitcoin payments and automatically

convert sales into bitcoin. And it will be fully rolled out this month.

Expanding distribution to reach more sellers

We believe this will be the strongest NVA year for Square ever, which we’ve accomplished through expanded field sales, partner programs, and

targeted marketing. Year to date through September, sales-led NVA has grown by 28%, and we expect it to grow by over 40% by the end of the year.

8 Inflows refers to funds entering the Cash App ecosystem. Inflows does not include the

movement of funds when funds remain in the Cash App ecosystem or when funds leave the Cash App ecosystem, or inflows related to the Afterpay app.

9 New Volume Added (NVA) is the total gross payment volume (GPV) processed, or expected to be processed, by new sellers during their first 12 months on Square. While intended to

represent incremental volume from new cohorts, it may also include GPV from existing sellers in cases such as new locations or event-based merchant tokens.

2

Even as we ramp our sales efforts, one of Square’s advantages continues to be how easily

sellers can get started on their own. Self-onboard growth has accelerated as we have invested in marketing, with growth expected to more than double in Q4 vs. Q1. We’re making it simpler to work with Square, with new pricing and packaging that

helps sellers discover more of our software solutions. This intuitive experience is a superpower for Square and we will continue to invest to drive strength.

The neighborhood is the future

We’re giving sellers in neighborhoods everywhere the tools they need to grow and navigate challenges. We’ve shown we can win in QSR by

combining deep product and go-to-market investment. Now, we’re expanding that approach across verticals, using AI and Neighborhoods on Cash App to help sellers

even more. We’re doing all of this while ramping our sales team, expanding partnerships, and investing in self-onboarding growth. We believe we are the only company that can serve every seller in every neighborhood around the world. And

we’re going to keep building for them.

Business Highlights

Cash App

Cash App hit 58 million monthly actives

in September. Our focus on expanding the network and increasing network density is working.

In August, we launched Cash App Pools to make

group money collection simple, and we have seen strong adoption, surpassing 1 million cumulative pools as of September. Pools are strengthening connections among existing customers and driving participation from people outside of Cash App.

Pools have increased network density and activity: Nearly half of contributors to the same pool have never paid each other before.

We’re

reaching teens at the start of their financial journey, helping them save, spend, and build healthy financial habits. Cash App Card is one of the most popular debit cards for teens in the US, and we’re continuing to launch products to serve

this audience.10 In September, we launched Teen Savings Yield, offering teens a 3.5% yield on their savings deposits. We also rolled out new parental controls including limits

on peer-to-peer transactions and Cash App Card spending, and sponsor-approved contact lists, empowering families to build healthy financial habits together.

We’re rolling out a number of marketing initiatives, giveaways, and influencer partnerships focused on driving adoption of financial services

products and reengaging actives who use Cash App infrequently. These targeted incentives are encouraging deeper adoption of products like Cash App Card: for example, a $20 activation offer for less engaged actives without a Cash App Card led to a

13% uplift in new card activations in testing.11

We’re

continuing to deepen engagement and increase product attach rates.

We have seen Square Releases drive engagement and excitement with our

seller base, while increasing development velocity. We’re now bringing that playbook to Cash App. On November 13, we’ll showcase our first Cash App Release to bring greater awareness of all the products we’re delivering to

improve the financial lives of our customers. At Cash App Releases we will unveil more about the future of AI and bitcoin in Cash App, and how we’re driving growth across our banking products.

We’re introducing “primary banking actives” as a key measure of how many customers use Cash App in their daily financial lives. As

of September, we served 8.3 million primary banking actives, up 18% year over year.12 In October we launched the Holo card, our latest addition to Cash App Card designs,

which enable customers to personalize what’s in their wallet and how their Cash App looks. We’ve seen prior card launches lead to increased interest in Cash App’s banking products, and we will share more about how we’re tying

spending across Cash App more closely to primary banking benefits at Cash App Releases.

We have continued to experience strong growth in

post-purchase BNPL on Cash App Card. We ended July at over $2 billion in annualized post-purchase originations, and in early October we crossed $3 billion.13 We also

continued to expand access to Cash App Borrow in the third quarter, with originations growing 134% year over year. We’re scaling Borrow while delivering strong annualized net margins of 24% and stable risk loss in the third quarter.14

10 Custom survey questions requested by Cash App through Morning Consult’s Omnibus

11 These results are from a test in June 2025 across a few

thousand Cash App actives.

12 Primary Banking Active is a Cash App account that

receives inflows from ACH or certain original credit transactions relating to earned wages, excluding tax refunds and ACH transfers, or spent at least $500 per month across Cash App, including Cash App Card, Cash App Pay, Afterpay through Cash App

and ACH bill pay during a specified period.

13 Post-purchase BNPL origination

volume is calculated based on annualized post-purchase BNPL originations during the period noted.

14 Cash App Borrow annualized net margin is calculated by taking Cash App Borrow variable profit margins on a per cohort basis and dividing it by the weighted average life of the loan cohort and

multiplying by 365. We calculate Cash App Borrow variable profit margins as variable profit divided by originations. We define variable profit as gross profit less processing costs and losses.

Square

At our second Square Releases event in October we showcased our unique AI capabilities to deliver differentiated value to sellers.

Since its launch earlier this year, Square AI has answered hundreds of thousands of questions from sellers, helping them get more done, faster.

Sellers are using it to get fast insights on a new menu item, identifying the top customers at every location each week, or running granular reports in seconds that previously took hours. Recent enhancements include local data insights, pinned data

on Dashboard, and mobile access on the Square Dashboard app. Donnie McClanahan, a Square seller who owns four cafes in Knoxville, Tennessee, uses Square AI to navigate complex business decisions. It’s helped him avoid cutting top-performing menu items and adjust store hours to save on costs without meaningfully impacting revenue.

We

began rolling out a new Square AI voice ordering tool in October to help sellers handle peak-hour demand. This tool gives sellers an AI assistant that can take orders over the phone and integrates seamlessly with Square ordering and kitchen display

technology. We also launched Order Guide, Square’s new AI-powered centralized procurement tool that helps restaurants bring all their vendor data into one place and gives sellers instant clarity to

compare offerings, track trends, and spot gaps across suppliers. Menus can be uploaded and automatically converted into complete ingredient lists, saving hours of manual work and streamlining procurement to give sellers more control over their

margins.

At Square Releases, we also highlighted several new features to better serve the needs of our sellers including Multichannel Menus,

which give complex omnichannel sellers operating across multiple locations with multiple menu items a single, streamlined way to set up and manage their menus across every channel and location.

We’re expanding distribution and reinvigorating our brand.

We launched a new campaign that spotlights individual neighborhoods and the sellers that bring them to life. It shows how we help sellers of all sizes

and verticals thrive — and positions Square as the preferred commerce platform for local businesses. We’re running the campaign nationally and in local markets, and we’re investing in pop-upexperiences and partnerships with iconic sellers to build brand awareness for Square and engage with sellers in their local communities.

We’re leveraging the strength of the Block ecosystem to help our partners and customers thrive. We announced a new partnership with Grubhub in

the third quarter that will provide sellers a more efficient way to manage delivery and pickup operations with a seamless integration embedded right in Square. We also announced Grubhub as a new Cash App Pay partner, providing Cash App customers

more choice and flexibility in how they want to pay and offering Grubhub a low-cost payment option that builds relationships with new customers.

As we increase our brand investments, we are simplifying our Square pricing and packaging into three tiers with different software and processing

price options, with the goal of increasing software attach rates in our seller base. We have seen that sellers that adopted our software solutions grew their GPV 9% faster and have higher retention after 12 months. We want to enable more sellers to

discover Square’s software functionality to help them succeed.

We are continuing to scale field sales and partnerships, ending the third

quarter with 90 field sales representatives. We’re also executing on our distribution strategies effectively in international markets with new volume added (NVA) growth accelerating, driven in part by the strength we’re seeing in

telesales.

T5We believe our efforts to move upmarket are working as we continue to sign new, large upmarket sellers. We recently signed Katz Deli,

a 137-year-old iconic New York institution, and Purdys Chocolatier, Canada’s chocolatier since 1907, which has more than 80 locations, marking Square’s

largest Canadian retail seller and one of our largest sellers globally.

Financial Discussion

Our financial performance was strong in the third quarter, with gross profit growth of 18% year over year and Adjusted Operating Income exceeding our

guidance. We are seeing strong momentum across Square and Cash App, with Square GPV growth and Cash App gross profit per monthly transacting active growth accelerating. In the third quarter, we increased Cash App monthly transacting actives to

58 million and Proto generated its first revenue, demonstrating velocity and innovation across Block. We are raising our fourth quarter and full-year guidance to reflect our strong execution. We expect to continue to accelerate gross profit

growth in the fourth quarter, exiting 2025 with year-over-year growth of over 19%, while G1delivering over 39% Adjusted Operating Income growth.

Third Quarter 2025 Financial Highlights

8.0 million in the second quarter. We continue to invest in Cash App Borrow and BNPL to deepen engagement.

Guidance

T6We are raising our guidance to reflect the strength we are seeing across our business. We now expect $10.243 billion in gross profit

for 2025, G2reflecting growth of over 15% year over year. We expect full year Adjusted Operating Income of $2.056 billion, or 20% margin, growing nearly 28% year over year. We expect gross profit in the fourth quarter to grow 19% year over year to

$2.755 billion with Adjusted Operating Income of $560 million, for Adjusted Operating Income margins of 20%.

15 Square GPV is defined as the total dollar amount of all card and bank payments processed by

sellers using Square, net of refunds.

16 Gross profit per monthly transacting

active is calculated based on Cash App annualized gross profit excluding our BNPL platform during a given quarter divided by the monthly transacting actives for the last month of the quarter. Cash App annualized gross profit includes gross profit

from our post-purchase BNPL on Cash App Card. In the third quarter, BNPL platform gross profit (which does not include post-purchase BNPL on Cash App Card) was $269 million.

Cash App gross profit increased 24% year

over year, driven by growth across Cash App Borrow, BNPL, and Cash App Card. Gross profit per transacting active reached $94 in the third quarter, up 25% year over year. Inflows per transacting active growth accelerated to 10% year over year in the

third quarter driven in part by more customers bringing their paychecks into Cash App. Primary banking actives reached 8.3 million, up 18% year over year as we continued to deliver more value and drive deeper engagement with more customers.

BNPL GMV reached $9.70 billion in the third quarter, growing 17% and 18% year over year on a reported and constant currency basis,

respectively. Growth was driven by post-purchase BNPL on Cash App Card, Gift Cards, and Single Use Payments. BNPL gross profit was $299 million, up 23% year over year.22Commerce volume grew 17% year over year to $49.7 billion in the third quarter, accelerating from 14% year-over-year growth in the second quarter driven by Cash App Card, BNPL, and Cash App Pay.23

17 We have recast prior period inflows to include refunds on Cash App Card transactions. This

presentation is consistent with the current period and affects reported inflows, inflows per active, and monetization rate.

18 Historically, our Cash App ecosystem has experienced improvements in revenue, gross profit, and inflows related to the distribution of government funds as customers have deposited more funds into

Cash App during these times, including during the first quarter when U.S. tax refunds are typically distributed.

19 Inflows per transacting active refers to total inflows in the quarter divided by monthly actives for the last month of the quarter. Inflows refers to funds entering the Cash App ecosystem. Inflows

does not include the movement of funds when funds remain in the Cash App ecosystem or when funds leave the Cash App ecosystem, or inflows related to the Afterpay app.

20 We calculate monetization rate by dividing Cash App gross profit, excluding contributions

from our BNPL platform, by Cash App inflows.

21 Gross profit per monthly

transacting active is calculated based on Cash App annualized gross profit excluding our BNPL platform during a given quarter divided by the monthly transacting actives for the last month of the quarter. Gross profit for our BNPL platform was

$242 million or $968 million on an annualized basis for Q3’24, $298 million or $1.19 billion on an annualized basis for Q4’24, $237 million or $948 million on an annualized basis for Q1’25,

$261 million or $1.04 billion on an annualized basis for Q2’25, and $269 million or $1.08 billion on an annualized basis for Q3’25.

22 BNPL GMV and BNPL gross profit include contributions from post-purchase BNPL on Cash App

Card.

Cash App sales and marketing expenses were up 14% year over year driven primarily by Cash App customer

acquisition spend, which grew by 60% year over year. Other sales and marketing expenses were up 23% year over year as we significantly increased go-to-market investment

in Square. General and administrative expenses were up 14% year over year on a GAAP basis, driven in part by an in-person company event. Excluding this expense, general and administrative expenses remained

roughly flat year over year in the third quarter. Transaction, loan, and consumer receivable losses increased 89% year over year on a GAAP basis, driven primarily by growth in loan volumes, particularly from Cash App Borrow (originations volume up

134% year over year).

“estimates,” “predicts,” “potential,” or “continue,” or the negative of these words or other similar terms or expressions that concern our expectations, strategy, plans, or intentions. Such statements

are subject to a number of known and unknown risks, uncertainties, assumptions, and other factors that may cause the Company’s actual results, performance, or achievements to differ materially from results expressed or implied in this letter.

Investors are cautioned not to place undue reliance on these statements, and reported results should not be considered as an indication of future performance.

Risks that contribute to the uncertain nature of the forward-looking statements include, among others, a deterioration of general

macroeconomic conditions; the Company’s investments in its business and ability to maintain profitability; the Company’s efforts to expand its product portfolio and market reach; the Company’s ability to develop products and

services to address the rapidly evolving market for payments and financial services; the Company’s ability to deal with the substantial and increasingly intense competition in its industry; acquisitions, strategic investments, entries into new

businesses, joint ventures, divestitures, and other transactions that the Company may undertake; the Company’s ability to ensure the integration of its services with a variety of operating systems and the interoperability of its technology

with that of third parties; the Company’s ability to successfully develop and integrate artificial intelligence into its systems, initiatives, and products; the Company’s ability to retain existing customers, attract new customers, and

increase sales to all customers; the Company’s dependence on payment card networks and acquiring processors; the effect of extensive regulation and oversight related to the Company’s business in a variety of areas; risks related to the

banking ecosystem, including through our bank partnerships, and FDIC and other regulatory obligations; the liabilities and loss potential associated with new products, product features, and services; litigation, including intellectual property

claims, government investigations or inquiries, and regulatory matters or disputes; the adequacy of reserves for such matters and the impact of any such matters or settlements thereof on our business; adoption of the Company’s products and

services in international markets; changes in political, business, and economic conditions, including changes due to actual or potential tariffs; as well as other risks listed or described from time to time in the Company’s filings with the

Securities and Exchange Commission (the SEC), including the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024, and its subsequent Quarterly Reports on Form 10-Q, which are on file with the SEC and available on the Investor Relations page of the Company’s website. Additional information will also be set forth in the Company’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2025. All forward-looking statements represent management’s current expectations and predictions regarding trends affecting the Company’s business and

industry and are based on information and

estimates available to the Company at the time of this letter and are not

guarantees of future performance. Earnings guidance for 2025 reflects assumptions the Company believes are reasonable as of the date of this filing, and actual results may vary based on changing macroeconomic conditions and other risks and

uncertainties outlined in this safe harbor section and in the Company’s periodic reports filed with the SEC. Except as required by law, the Company assumes no obligation to update any of the statements in this letter.

Key Operating Metrics And Non-GAAP Financial Measures

To supplement our financial information presented in accordance with generally accepted accounting principles in the United

States (GAAP), from period to period, we consider and present certain operating and financial measures that we consider key metrics or are not prepared in accordance with GAAP, including Gross Payment Volume (GPV), Gross Merchandise Value (GMV),

Adjusted EBITDA, Adjusted EBITDA margin, Adjusted Net Income (Loss), Diluted Adjusted Net Income (Loss) Per Share (Adjusted EPS), Adjusted Operating Income (Loss), Adjusted Operating Income (Loss) margin, Adjusted Free Cash Flow, constant currency,

and non-GAAP operating expenses. We believe these metrics and measures are useful to facilitate period-to-period comparisons of

our business and to facilitate comparisons of our performance to that of other payments solution providers. GPV includes Square GPV and Cash App Business GPV. Square GPV is defined as the total dollar amount of all card and bank payments processed

by sellers using Square, net of refunds. Cash App Business GPV comprises Cash App activity related to peer-to-peer transactions received by business accounts and peer-to-peer payments sent from a credit card. GPV does not include transactions from our BNPL platform. We define GMV as the total order value processed on our BNPL platform.

Adjusted Net Income (Loss) and Diluted Adjusted Net Income (Loss) Per Share (Adjusted EPS) are non-GAAP financial measures that represent our net income (loss) and net income (loss) per share, adjusted to eliminate the effect of restructuring share-based compensation expense, contingencies, restructuring, and

other charges; goodwill and intangible asset impairment; amortization of intangible assets; amortization of debt discount and issuance costs; gain or loss on revaluation of equity investments; remeasurement gain or loss on revaluation of bitcoin

investment; the gain or loss on the disposal of property and equipment; acquired deferred revenue and cost adjustments; the tax effects of income tax benefits from deferred taxes; and the tax effect ofnon-GAAP net income adjustments, as applicable. Additionally, for purposes of calculating diluted Adjusted EPS, we add back cash interest expense on convertible senior notes, as if converted at the beginning

of the period, if the impact is dilutive. To calculate the diluted Adjusted EPS, we adjust the weighted-average number of shares of common stock outstanding for the dilutive effect of all potential shares of common stock. In periods when we recorded

an Adjusted Net Loss, the diluted Adjusted EPS is the same as basic Adjusted EPS because the effects of potentially dilutive items were anti-dilutive given the Adjusted Net Loss position.

Adjusted EBITDA and Adjusted EBITDA margin are non-GAAP financial measures that

represent our net income (loss), adjusted to exclude share-based compensation expense; restructuring share-based compensation expense; depreciation and amortization; contingencies, restructuring, and other charges; interest income and expense;

remeasurement gain or loss on bitcoin investment; other income and expense; provision for (benefit from) income taxes; gain or loss on disposal of property and equipment; and acquired deferred

revenue and cost adjustment, as applicable. Adjusted EBITDA margin is calculated as Adjusted EBITDA divided by gross profit.

Adjusted Operating Income (Loss) is a non-GAAP financial measure that represents our operating income (loss), adjusted to eliminate the effect of amortization of acquired technology assets;

contingencies, restructuring, and other charges; restructuring share-based compensation expenses; goodwill and intangible asset impairment and amortization of customer and other acquired intangible assets. Adjusted Operating Income (Loss) margin is

calculated as Adjusted Operating Income (Loss) divided by gross profit.

We also exclude from these measures certain

acquisition-related and integration costs associated with business combinations, and various other costs that are not reflective of our core operating performance. We exclude amortization of intangible assets arising from business combinations from

Adjusted Net Income (Loss), Adjusted EPS, Adjusted Operating Income (Loss), and Adjusted Operating Income (Loss) Margin because the amount of such expenses in any specific period may not directly correlate to the underlying performance of our

ongoing business operations. Acquisition-related costs include amounts paid to redeem acquirees’ unvested stock-based compensation awards; charges associated with holdback liabilities; and legal, accounting, and due diligence costs.

Integration costs include advisory and other professional services or consulting fees necessary to integrate acquired businesses. Other costs that are not reflective of our core business operating expenses may include contingencies, restructuring,

and other charges; impairment charges; restructuring share-based compensation expense; and certain litigation and regulatory charges. For Adjusted Net Income (Loss) and Adjusted EPS, we also add back the impact of the acquired deferred revenue and

deferred cost adjustment, which was written down to fair value in purchase accounting, and adjust for the tax effect of the non-GAAP net income adjustments.

Adjusted Free Cash Flow is a non-GAAP financial measure that represents our net cash

provided by operating activities adjusted for changes in settlements receivable; changes in customers payable; changes in settlements payable; the purchase of property and equipment; payments for originations of consumer receivables; proceeds from

principal repayments and sales of consumer receivables; purchases and originations of loans originally classified as held for investment; proceeds from repayments of loans originally classified as held for investment; and sales, and principal

payments, and forgiveness of PPP loans. We present Adjusted Free Cash Flow because we use it to understand the cash generated by our business and make strategic decisions related to our balance sheet, and because we are focused on growing our

Adjusted Free Cash Flow generation over time. It is not intended to represent amounts available for discretionary purposes. Constant currency growth is calculated by assuming international results in a given period and the comparative prior period

are translated from local currencies to the U.S. dollar at rates consistent with the monthly average rates in the comparative prior period. We discuss growth on a constant currency basis because a portion of our business operates in markets outside

the U.S. and is subject to changes in foreign exchange rates. Non-GAAP operating expenses is a non-GAAP financial measure that represents operating expenses adjusted to

remove the impact of restructuring share-based compensation; amortization of customer and other acquired intangible assets; acquisition-related and integration costs; contingencies, restructuring, and other charges; and goodwill and intangible asset

impairment. We have included Adjusted EBITDA, Adjusted EBITDA margin, Adjusted Operating Income (Loss), Adjusted Operating Income (Loss) margin, Adjusted Net Income, Adjusted EPS, and non-GAAP operating

expenses because they are key measures used by our management to evaluate our operating performance, generate future operating plans, and make strategic decisions, including those relating to operating expenses and the allocation of internal

resources.

Accordingly, we believe that Adjusted EBITDA, Adjusted EBITDA margin, Adjusted

Operating Income (Loss), Adjusted Operating Income (Loss) margin, Adjusted Net Income, Adjusted EPS, and non-GAAP operating expenses provide useful information to investors and others in understanding and

evaluating our operating results in the same manner as our management and board of directors. In addition, they provide useful measures for period-to-period comparisons

of our business, as they remove the effect of certain non-cash items and certain variable charges that do not vary with our operations. We have included measures excluding our BNPL platform because we believe

these measures are useful in understanding the ongoing results of our operations. Adjusted EBITDA, Adjusted EBITDA margin, Adjusted Net Income, Adjusted Operating Income (Loss), Adjusted Operating Income (Loss) margin, Adjusted EPS, and non-GAAP operating expenses, as well as other measures defined in the shareholder letter, such as measures excluding our BNPL platform, have limitations as financial measures, should be considered as supplemental in

nature, and are not meant as substitutes for the related financial information prepared in accordance with GAAP. We believe that the aforementioned metrics and measures provide useful information about our operating results, enhance the overall

understanding of our past performance and future prospects, and provide useful measures for period-to-period comparisons of our business, as they remove the effect of

certain variable amounts, or they remove amounts that were not repeated across periods and therefore make comparisons more difficult. Our management uses these measures to evaluate our operating performance, generate future operating plans, and make

strategic decisions, including those relating to operating expenses and the allocation of internal resources. These non-GAAP financial measures should not be considered in isolation from, or as a substitute

for, financial information prepared in accordance with GAAP. These non-GAAP financial measures are not based on any standardized methodology prescribed by GAAP. Other companies, including companies in our

industry, may calculate the non-GAAP financial measures differently or not at all, which reduces their usefulness as comparative measures.
