Item 2.02 Results of Operations and Financial Condition

On November 10, 2021, Duolingo, Inc. (the “Company”) issued a press release announcing the financial results of the Company for the three and six months ended June 30, 2021. A copy of the press release is being furnished as Exhibit 99.1 attached hereto and is incorporated by reference herein.

In accordance with General Instruction B.2 of Form 8-K, the information in this Item 2.02 of this Current Report on Form 8-K, including Exhibit 99.1 attached hereto, shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.

Item 8.01 Other Events

In connection with the initial public offering of Class A common stock (the “IPO”) of Duolingo, Inc. (the “Company”), each of the Company’s officers and directors and holders of substantially all of the Company’s outstanding capital stock entered into lock-up agreements with the underwriters for the IPO (the “Underwriters”) that, subject to certain exceptions and partial early release provisions, restrict the ability of such holders to sell or transfer any shares of the Company’s capital stock for 180 days after July 27, 2021, the date of the final prospectus for the IPO (the “lock-up period”), which is January 23, 2022.

On November 10, 2021, the following early release conditions set forth in the lock-up agreements were satisfied with respect to a portion of the shares subject to such lock-up agreements: (1) the Company announced its financial results for its three months ended September 30, 2021, and (2) the last reported closing price of the Company’s Class A common stock was greater than $102.00 per share for 10 trading days (including the last day) out of any 15-consecutive trading day period.

As a result, the Company estimates that approximately 11 million shares of the Company’s Class A common stock will become eligible for sale in the public market at the open of trading on November 15, 2021, subject to applicable restrictions under the Securities Act of 1933, as amended, including Rule 144 and Rule 701. Any shares not released pursuant to these partial early release provisions will remain subject to the restrictions set forth in the lock-up agreements for the reminder of the lock-up period.

Duolingo Announces Third Quarter 2021 Results

Pittsburgh, PA – November 10, 2021 – Duolingo, Inc. (NASDAQ: DUOL), the world’s leading mobile language platform, today announced financial results for the quarter ended September 30, 2021.

"Our performance during the third quarter was exceptional. We achieved record bookings and a record number of paid subscribers, with monthly and daily users also reaching all-time highs," said Luis von Ahn, Co-Founder and CEO of Duolingo. "I’m very proud that we continue to grow rapidly, even on top of last year’s extraordinary performance, furthering our mission to develop the best education in the world and make it universally available."

Third Quarter 2021 Operational Highlights

Total bookings were $73.1 million, an increase of 57% from the prior year quarter;
Subscription bookings were $55.4 million, an increase of 64% from the prior year quarter;
Paid Subscribers totaled 2.2 million at quarter end, an increase of 49% from the prior year quarter;
Monthly active users (MAUs) were 41.7 million and daily active users (DAUs) were 9.8 million, both of which are all-time highs.

Third Quarter 2021 Financial Highlights

Total revenues were $63.6 million, an increase of 40% from the prior year quarter;
Gross Profit was $45.5 million, an increase of 41% from the prior year quarter;
Net loss totaled $29.0 million, compared to a net loss of $3.2 million in the prior year quarter, with the majority of this change driven by IPO-related costs;
Adjusted EBITDA was a loss of $6.0 million, compared to a loss of $0.7 million in the prior year quarter.

Summary of Financial Results

Revenues increased 40% to $63.6 million during the quarter, primarily driven by an increase in subscription revenues. Subscription revenues grew 42%, primarily due to an increase in the average number of paid subscriptions during the quarter. Advertising revenues increased 34% to $9.0 million, due to an increase in DAUs, which resulted in increased advertisements served, as well as a year-over-year increase in advertising revenue per DAU. Duolingo English Test revenue grew 19% to $6.7 million due to growth initiatives that drove the number of tests taken, highlighting the durability of the growth that began during the COVID-19 pandemic. Other revenue increased 179% to $1.8 million during the quarter due to growth in in-app purchases.

The table below provides the changes in revenue by product type:

Three Months Ended September 30,
(in thousands)20212020Change% Change
Subscription$46,030 $32,317 $13,713 42 %
Advertising9,029 6,720 2,309 34 %
Duolingo English Test6,695 5,607 1,088 19 %
Other1,841 661 1,180 179 %
Total revenues$63,595 $45,305 $18,290 40 %


Gross margin
increased to 71.6% compared to 71.1% in the year-ago quarter. This was driven by a combination of reduced payment processing fees on subscriptions due to improved retention and mix and by higher advertising revenue per DAU, offset by additional test proctoring costs for the DET.

Operating expenses increased $38.9 million or 110% over the prior year quarter primarily driven by higher stock compensation expense recorded upon the initial public offering (“IPO”). Research and development increased 85% to $29.3 million, primarily due to an increase in employee costs of $10.6 million, $1.3 million of which relates to restricted stock units (RSU) compensation expense recorded upon the IPO. Sales and marketing increased 37% to $15.3 million primarily due to increased spending on media and brand around the IPO and to support both our growth during the back-to-school period, as well as $0.6 million of additional expenses related to employee costs including RSU compensation



expense recorded upon the IPO. General and administrative increased 260% to $29.6 million, primarily due to increased employee-related costs. These costs include $14.3 million of stock based compensation expense which was recognized upon the IPO, consisting of expense for performance-based RSUs issued to our founders, and the acceleration of founder stock options and RSUs granted in prior periods where the performance-based vesting condition was satisfied upon the IPO. We also incurred higher professional fees of $1.3 million, mainly related to IPO and public readiness costs.

Net loss (GAAP) totaled $29.0 million, compared to a net loss of $3.2 million in the prior year quarter. This larger net loss was primarily attributable to costs associated with becoming a public company in the third quarter, including $15.9 million of IPO-related and founder stock-based compensation expense and $1.6 million of IPO and public company readiness costs.

Adjusted EBITDA was a loss of $6.0 million compared to a loss $0.7 million of in the prior year quarter. The decrease in adjusted EBITDA occurred because operating expenses, adjusted for costs incurred related to IPO and public company readiness and other costs which did not occur in the prior year, grew at a higher rate than revenue and gross profit.

Financial Outlook

Duolingo is providing the following guidance for the fourth quarter and the full year ending December 31, 2021.
Fourth Quarter 2021Full Year 2021
(in millions)LowHighLowHigh
Total Bookings$79.0$82.0$282.5$285.5
Revenues$66.5$69.5$244.0$247.0
Adjusted EBITDA$(6.5)$(3.5)$(8.0)$(5.0)

With regards to the Non-GAAP Adjusted EBITDA outlook provided above, a reconciliation to GAAP net earnings (loss) has not been provided as the quantification of certain items included in the calculation of GAAP net earnings (loss) cannot be calculated or predicted at this time without unreasonable efforts. For example, the non-GAAP adjustment for stock-based compensation expense requires additional inputs such as number of shares granted and market price that are not currently ascertainable, and the non-GAAP adjustment for certain legal, tax and regulatory reserves and expenses depends on the timing and magnitude of these expenses and cannot be accurately forecasted. For the same reasons, we are unable to address the probable significance of the unavailable information, which could have a potentially unpredictable, and potentially significant, impact on our future GAAP financial results.

Webcast and Conference Call Information
Duolingo will host a conference call to discuss its quarterly results today, November 10, at 5:30 p.m ET. The live webcast of Duolingo’s earnings conference call will be publicly available and can be accessed at investors.duolingo.com. A replay will be available on the Investor Relations website one hour following completion of the call.

Definitions

Subscription Bookings and Total Bookings. Subscription bookings represent the amounts we receive from a purchase of a subscription to Duolingo Plus. Total bookings represent the amounts we receive from a purchase of a subscription to Duolingo Plus, a registration for a Duolingo English Test, an in-app purchase for a virtual good and from advertising networks for advertisements served to our users. We believe bookings provide an indication of trends in our operating results, including cash flows, that are not necessarily reflected in our revenue because we recognize subscription revenue ratably over the lifetime of a subscription, which is generally from one to twelve months.

Monthly Active Users (MAUs). MAUs are defined as unique Duolingo users who engage with our mobile language learning application or the language learning section of our website each month. MAUs are reported for a measurement period by taking the average of the MAUs for each calendar month in that measurement period. MAUs are a measure of the size of our global active user community on Duolingo.

Daily Active Users (DAUs). DAUs are defined as unique Duolingo users who engage with our mobile language learning application or the language learning section of our website each calendar day. DAUs are reported for a measurement period by taking the average of the DAUs for each day in that measurement period. DAUs are a measure of the consistent engagement of our global user community on Duolingo.

Paid Subscribers. Paid subscribers are defined as users who pay for access to Duolingo Plus and had an active subscription as of the end of the measurement period. Each unique user account is treated as a single paid subscriber regardless of whether such user purchases multiple subscriptions, and the count of paid subscribers does not include users who are currently on a free trial.


Forward-Looking Statements
This press release contains forward-looking statements regarding our future expectations, including but not limited to statements regarding our future financial performance and outlook for the fourth quarter and full year 2021. These forward-looking statements are based on our current assumptions, expectations and beliefs, are only predictions and may differ materially from actual results due to a variety of factors including but not limited to risks related to (1) our ability keep existing users or add new users, or the potential that our existing users decrease their level of engagement with our products or do not convert to paying users, (2) the highly competitive online learning language industry, (3) changes to our existing brand and products, or the introduction of a new brand or products, which could fail to attract or keep users, (4) growing costs and investments that may have the effect of reducing our operating margin and profitability, (5) inherent challenges in measurement of user metrics and other estimates, (6) our ability to maintain good relationships with third-party platforms to distribute our products, (7) third-party hosting and cloud computing providers, (8) complex and evolving US and international laws and regulations



applicable to our business, (9) our ability to access, collect, and use personal data about our users and payers, and to comply with applicable data privacy laws, (10) varying and rapidly-evolving regulatory framework on privacy and data protection across jurisdictions, (11) potential intellectual property-related litigation and proceedings, and (12) our ability adequately obtain, protect and maintain our intellectual property rights. These and other potential risks and uncertainties that could cause actual results to differ from the results predicted are more fully detailed under the caption "Risk Factors" in our Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2021 which are accessible on the SEC’s website at www.sec.gov and the Company’s Investor Relations website at https://investors.duolingo.com. Additional information will be made available in our Quarterly Report on Form 10-Q for the quarter ended September 30, 2021 and other filings and reports that we may file from time to time with the SEC. We undertake no obligation to update these statements as a result of new information or future events.

Non-GAAP Financial Measures
We use certain non-GAAP financial measures to supplement our consolidated financial statements, which are presented in accordance with GAAP. These non-GAAP financial measures include Adjusted EBITDA. Please refer to the definitions and reconciliations at the end of this press release. We use these non-GAAP financial measures for financial and operational decision-making and as a means to evaluate period-to-period comparisons. By excluding certain items that may not be indicative of our recurring core operating results, we believe that Adjusted EBITDA provides meaningful supplemental information regarding our performance. Accordingly, we believe these non-GAAP financial measures are useful to investors and others because they allow for additional information with respect to financial measures used by management in its financial and operational decision-making and they may be used by our institutional investors and the analyst community to help them analyze the health of our business. However, there are a number of limitations related to the use of non-GAAP financial measures, and these non-GAAP measures should be considered in addition to, not as a substitute for or in isolation from, our financial results prepared in accordance with GAAP. Other companies, including companies in our industry, may calculate these non-GAAP financials measures differently or not at all, which reduces their usefulness as comparative measures.

Website Information
We routinely post important information for investors on the Investor Relations section of our website, https://investors.duolingo.com and also from time to time may use social media channels, including our Twitter account (twitter.com/duolingo) and our LinkedIn account (linkedin.com/company/duolingo/), as an additional means of disclosing public information to investors, the media and others interested in us. It is possible that certain information we post on our website and on social media could be deemed to be material information, and we encourage investors, the media and others interested in us to review the business and financial information we post on our website and on the social media channels identified above, in addition to following our press releases, SEC filings, public conference calls, presentations and webcasts. The information contained on, or that may be accessed through, our website and our social media channels is not incorporated by reference into, and is not a part of, this document.
