Consensus scorecard

Reported results and guidance

• Scorecard recap: revenue of $298.5m beat consensus by 1.0% and GAAP diluted EPS of $0.66 beat the $0.604 estimate by 9.3%.
• Duolingo reaffirmed its full-year bookings and revenue growth targets and raised the full-year adjusted EBITDA margin outlook by nearly one point to approximately 26.5%.
• DAU growth of 23% accelerated two percentage points sequentially; MAU growth of 10% accelerated four points. Management attributes the acceleration to product changes, marketing impact, and a one-time event to revive lost streaks, and says two of the three are permanent, so DAU growth should stay above the 20% previously guided.
• Bookings growth of 8% (6% constant currency) slowed on a tough prior-year comparison that included the initial Energy rollout, a price increase, and advertising outperformance.
• Gross margin of 72.6% came in ahead of the company's own approximately 71.0% expectation on AI cost efficiencies and a measured pace of AI feature expansion.
• The company ended the quarter with approximately $1.3 billion of cash and short-term investments.
• Under the $400m repurchase program announced in February, approximately $44.4m (about 432 thousand shares) was repurchased in Q2 and approximately $71.9m (about 708 thousand shares) through 1 August 2026, which management says represents nearly all of 2024 and 2025 dilution.
• CURR, the company's stickiness metric, is at an all-time high of 84%, up about one point year over year.
• Over half of bookings come from outside the U.S.; management estimates every 1% move in the dollar against its currency basket is about a $4m impact on second-half bookings.

Key bullish aspects

• Both scorecard metrics beat: revenue by 1.0% and GAAP diluted EPS by 9.3%.
• DAU growth accelerated to 23% from the prior quarter and ran ahead of management's own expectations, and the company now expects DAU growth to stay above the 20% it had previously guided for the rest of the year.
• Revenue grew 18.3% to $298.5m and gross profit grew faster at 18.7%, with gross margin up 20 basis points to 72.6% against an internal expectation of about 71.0%.
• The full-year adjusted EBITDA margin outlook was raised by nearly a point to approximately 26.5%, with the raise attributed to gross-margin flow-through rather than to cost cuts.
• Paid subscribers rose 17% to 12.7 million and subscription bookings rose 10% to $250.3m, so the paying base is still compounding even in a year the company describes as prioritizing user growth over monetization.
• CURR reached an all-time high of 84%; because retention compounds into DAU, the company treats this as a leading indicator, and it improved while monetization was deliberately de-emphasized.
• The balance sheet strengthened: cash and equivalents rose 13.9% since year end to $1,180.9m, total cash and short-term investments are about $1.3bn, and there is no debt on the balance sheet.
• Buybacks of about $71.9m through 1 August offset nearly all 2024 and 2025 dilution, against a $400m authorization, so a large majority of the program remains available.
• Accounts receivable fell 19.6% since year end to $131.0m while revenue grew, and deferred revenue of $505.1m still exceeds two quarters of the trailing revenue run rate.
• Gross margin guidance for both Q3 (~71.0%) and the full year (~71.6%) was described as better than the trajectory outlined on the Q1 call, on AI cost trends.

Key bearish aspects

• Net income fell 26.0% to $33.2m and diluted EPS fell 27.5% to $0.66 even as revenue grew 18.3%; the consensus EPS beat is against a materially lower year-over-year number.
• Operating leverage disappeared: total operating expenses rose 22.5% against 18.3% revenue growth, so income from operations grew only 1.7% to $33.9m and the operating margin fell to 11.4% from 13.2%.
• Sales and marketing rose 35.3% to $40.0m and research and development rose 25.1% to $92.2m, both far ahead of revenue; the DAU acceleration is partly bought.
• Adjusted EBITDA fell 2% to $77.3m and its margin fell 530 basis points to 25.9%; free cash flow fell 9% to $78.6m with margin down 790 basis points to 26.3%.
• Bookings, the forward-looking cash metric, grew only 8% (6% constant currency) to $289.1m against 18.3% revenue growth, so revenue growth is running well ahead of the cash coming in the door.
• Bookings of $289.1m were below reported revenue of $298.5m in the quarter, which draws down the deferred revenue that supports future recognized revenue.
• The effective tax rate jumped to 26.9% from 3.6%, and the full-year guide of 23-25% means the prior year's low-tax comparison does not return.
• Guidance implies deceleration: Q3 bookings growth of 8.9% and revenue growth of 11.1% are both below the quarter just reported, and full-year revenue growth of 16.3% against 18.3% this quarter implies a slower second half.
• Full-year bookings growth guidance of 10.9% sits at the low end of the 10-12% target range the company says it is maintaining.
• Part of the DAU acceleration is explicitly a one-time event to revive lost streaks, which management acknowledges is not permanent.
• Stock-based compensation is guided to around 15.0% of revenue for 2026 with absolute expense increasing through the year, and equity-grant dilution of 3.5-4.0% still exceeds the pace of buybacks completed so far.
• Long-term investments fell 24.0% since year end to $102.7m and deferred tax assets fell 9.4% to $206.0m; accounts payable more than doubled to $16.2m.

Key uncertainties

• The letter does not quantify how much of the 23% DAU growth came from the one-time lost-streak revival event versus the two factors management calls permanent, so the sustainable DAU growth rate is not determinable from this document.
• Bookings and revenue are diverging (8% versus 18.3% growth) and the letter attributes the bookings slowdown to prior-year comparisons rather than to demand; whether the gap closes is not addressed with a subscriber-level bridge.
• The guidance assumes foreign exchange rates as of 31 July 2026, and management sizes a 1% dollar move at about $4m of second-half bookings, but the letter does not disclose the currency basket composition.
• No reconciliation of forward-looking adjusted EBITDA to GAAP net income is provided, on the grounds that stock-based compensation and legal, tax and regulatory reserves cannot be predicted without unreasonable effort.
• "Legal, tax and regulatory reserves" is named as an adjusted EBITDA reconciling item, but no current legal or regulatory matter is described or sized in this letter.
• The prior-year effective tax rate of 3.6% is not explained here, so the year-over-year earnings decline cannot be split between operating investment and tax normalization from this document alone.
• Video Call is described as available to most new Super Duolingo subscribers with extension to existing subscribers later this year; the letter does not quantify its cost, its effect on gross margin, or its effect on conversion.
• Longer free trials are cited as a monetization test with "good early results" expected to increase both revenue and DAU, but no sizing, cohort data, or timing is given.
• The Duolingo English Test, advertising, and in-app purchases are included in total bookings but are not broken out, so the 8% total bookings growth against 10% subscription bookings growth implies a decline in the non-subscription lines that the letter does not quantify.
• Q3 adjusted EBITDA is guided to $76.0m at a 25.2% margin, below both the $77.3m and 25.9% just reported and the 26.5% full-year margin target, which implies the margin recovery is weighted to the fourth quarter; the letter does not bridge that step-up.
• The reconciliation appendix, cash flow statement, and the remaining pages of the 24-page letter were not read for this preliminary; adjusted EBITDA, free cash flow, and their margins are taken from the summary metrics table and the CFO's section.
• The 5:00 p.m. ET video webcast had not occurred at the time of this report; management's answers on bookings deceleration, monetization pacing, and the second-half margin path are not assessed at this stage.

Market context

• API Ninjas snapshot: DUOL $135.32 on NASDAQ, volume 1,603,203, quote timestamped 2026-08-05T20:12:39Z, retrieved 2026-08-05T20:33:00Z. The letter was published after the U.S. close on 2026-08-05; this is a single quote of unstated session basis captured minutes after the close, not a measured reaction to the release. For reference, the letter states a share price of $115.02 as of 30 June 2026 for its dilutive-securities table.

Source limitations

• Every actual above comes from the Quartr Q2 2026 shareholder letter (3671708) and the accompanying press release (3671707). The press release itself contains no financial statements; all figures come from the letter. Quartr standardized financials for this event are not yet populated.
• API Ninjas supplied no actual or difference fields for this event, so each beat/miss is calculated locally as Quartr actual minus API Ninjas estimate. The API row carried no fiscal year or quarter, so the exact ticker-and-event-date match path was used.
• Year-over-year percentage changes, margin percentages, and effective tax rates not printed in the letter are calculated from the letter's own columns; where the letter prints its own percentage, the letter's figure is shown.
• Adjusted EBITDA, adjusted EBITDA margin, free cash flow, and free cash flow margin are non-GAAP measures as defined by the company and are stated in the letter to one decimal place in millions; the underlying reconciliation appendix was not read for this preliminary.
• The balance-sheet change column compares 30 June 2026 to 31 December 2025, not to the prior-year quarter.
• The condensed consolidated statements in this letter are unaudited.
• The prior-year CURR figure is not stated directly; the letter says CURR is at an all-time high of 84%, "up by about 1% from last year."
• The letter contains no segment or geographic revenue table.
