Explanatory Note

This Amendment No. 1 on Form 8-K/A (the “Amendment”) amends the Current Report on Form 8-K filed by Duolingo, Inc. (the “Company” or “Duolingo”) on May 8, 2024 (the “Original 8-K”). Except as provided below, the Original 8-K is otherwise unaltered by this Amendment.

Item 2.02 Results of Operations and Financial Condition

On May 8, 2024, Duolingo, Inc. (the “Company”) issued a press release announcing the financial results of the Company for the three months ended March 31, 2024 (the “Earnings Release”) and furnished with the Original 8-K as Exhibit 99.2 thereto (the “Original 8-K Exhibit”) a Shareholder Letter, dated May 8, 2024 (the “Original Shareholder Letter”). The Original Shareholder Letter was also posted to the Company’s website at investors.duolingo.com. On May 9, 2024, the Company learned of a technical error with the system through which the Original 8-K was filed with the SEC’s EDGAR system and that the information contained in the bar charts shown on page 9 of the Original 8-K Exhibit and in the bar charts under the heading “Non-GAAP Operating Expenses (% of Revenue)” on page 10 of the Original 8-K Exhibit were not correctly reflected. The sole purpose of this Amendment is to correct the Original 8-K Exhibit so that the bar charts are correctly reflected in the version of the Original Shareholder Letter on file with the SEC. The Original Shareholder Letter posted to the Company’s website correctly reflects these bar charts and remains unchanged. No other information in the Original 8-K Exhibit was incorrectly presented. This Amendment should be read in conjunction with the Earnings Release.

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 99.2 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.

About Duolingo Inc. (DUOL) Earnings

This page provides Duolingo Inc. (DUOL) earnings call transcripts from SEC 8-K filings along with AI-powered predictions for post-earnings price movements. Our machine learning models analyze historical earnings data, pre-earnings price patterns, volume changes, and volatility to predict 1-day, 5-day, and 20-day returns after each earnings release.

Earnings transcripts are sourced directly from SEC EDGAR filings. Predictions are generated using gradient boosting models trained on DUOL's historical earnings reactions. All predicted returns are shown as percentages, and predicted prices are calculated from the closing price at the time of prediction. Past performance does not guarantee future results.
