Insider sales (SEC Form 4, open-market, last ~7 months) (DUOL)

9 of 12 under a Rule 10b5-1 trading plan (scheduled in advance). Unplanned sales were timed by the insider.

% of holdings sold = shares sold ÷ (shares sold + all holdings the insider reported on that Form 4, direct and through trusts).

Insider type follows Cohen, Malloy & Pomorski (Journal of Finance, 2012). An insider who traded the stock in the same calendar month in each of the past three years is a routine trader; one who traded in each of those years without such a pattern is an opportunistic trader. In their study, trades by opportunistic insiders predicted future returns and trades by routine insiders did not. Counts open-market purchases and sales only (SEC Form 4 codes P and S) by that insider in that company. Not investment advice.

Key Strengths & Strategy (as disclosed to the SEC)

• Products across our platform, like our flagship Duolingo App (including our Math, Music, and Chess courses), and the Duolingo English Test, share a singular technology infrastructure, which allows us to leverage operational efficiencies in implementing new features for each.
• We further protect the use of our proprietary technology and intellectual property through provisions in both our user terms of use on our website and in our agreements with service providers.
• We also enter into, and rely on, confidentiality and proprietary rights agreements with our employees, consultants, contractors and business partners to protect our trade secrets, proprietary technology and other confidential information.
• With nearly 2 billion exercises completed every day on our platform, we believe we have built the world's largest collection of language-learning data.

Legal & Regulatory Risks (Item 1A, quoted)

• Our failure to comply with U.S. and foreign export controls, sanctions and other trade laws and regulations could have a material adverse effect on our business.
• We rely on a mixture of mechanisms to transfer personal data from the EEA and the U.K. to the U.S. and other jurisdictions deemed non-adequate and continue to evaluate what additional mechanisms may be required to establish adequate safeguards for personal data.
• The myriad international and U.S. privacy and data security laws are not consistent, and compliance is difficult and may be costly.
• Our development, implementation and use of AI and machine learning technologies, including third-party technologies, may not be successful, which may impair our ability to compete effectively, result in reputational harm and have an adverse effect on our business.
