Financials - What the Numbers Say

Duolingo crossed $1B in annual revenue in FY2025, with operating margin lifting to 13.1% from negative territory just two years earlier and free cash flow reaching $370M (35.6% FCF margin). The reported FY2025 net income of $414M, however, is inflated by a one-time release of the deferred-tax valuation allowance worth ~$232M; on a pretax basis the business earned $182M, which is the cleaner number to underwrite. Cash conversion is excellent (FCF is 0.95x operating cash flow), the balance sheet holds $1.05B of net cash with effectively no debt, and FY2025 returns on invested capital cleared 50%. The valuation tells a different story than the income statement: after a 65% drawdown from the FY2024 close, DUOL now trades at ~3.8x EV/Revenue and ~17x forward earnings — multiples that price in the recent deceleration (revenue growth slowing from 41% to 27% year on year and bookings guidance stepping down to ~10.5% for 2026) rather than the underlying margin expansion. The single financial metric to watch is bookings growth, which leads revenue by two quarters and is the line analysts have used to reset price targets.

Reading guide for financial scores you may have seen elsewhere: Quality Score is a 0-100 composite of profitability, financial strength, and growth durability; Fair Value is a model estimate of what the stock is worth on its history of returns and growth. Neither is currently available in our dataset for DUOL, so this page leans on first-principles ratios and peer multiples instead.

Revenue, Margins, and Earnings Power

Revenue compounded at 71% CAGR from FY2019 to FY2025, accelerating after the Q4 2022 generative-AI scare and through the 2023-2024 "Family Plan + Super Duolingo" subscription cycle. The shape of the income statement flipped in 2023-2024: gross margin sits steadily in the low-70s (typical of software with App Store and AWS costs in COGS), while operating margin moved from -23.9% in FY2021 to +13.1% in FY2025 — almost entirely on operating leverage over S&G and R&D, not gross-margin gains.

The FY2025 net margin spike to 39.9% is a tax-driven optical illusion. Operating margin — the line management actually steers — moved from 8.4% in FY2024 to 13.1% in FY2025, a +4.7pp expansion. R&D as a percent of revenue fell from 31.4% to 29.5%, and S&G from 33.0% to 29.6%; gross margin gave back 50 bps as AI inference costs rose. Earnings power is still expanding but at a slower pace than 2023→2024 (+11pp).

This is the chart the sell-side reacted to in February and May 2026: revenue growth held near 40% through Q3 FY2025, decelerated to 35% in Q4, then stepped down to 27% in Q1 FY2026. Management framed 2026 as a "transition year" with deliberate prioritization of daily-active-user growth over near-term monetization, which is consistent with the gap between still-strong revenue and softer bookings.

Cash Flow and Earnings Quality

Free cash flow is cash from operations minus capital expenditures — the cash the business produces after running and growing itself, before paying lenders or shareholders. For Duolingo, FCF turned positive in FY2020 and has compounded faster than revenue ever since.

For FY2019-FY2022, net income was deeply negative while operating cash flow was positive — the classic signature of a subscription software business where the cash from annual prepayments lands before the revenue is recognized. That dynamic still helps: in FY2025 cash from operations of $388M was driven by $137M of stock-based compensation (a non-cash expense) plus working-capital tailwinds from deferred revenue. Capex stays light at ~1.7% of revenue.

Major cash-flow distortions in FY2025

Balance Sheet and Financial Resilience

Duolingo carries no traditional debt — the $93M of liabilities classified as "debt" in the ratios file is operating-lease obligations on its Pittsburgh and global offices. Cash and equivalents reached $1.14B at year-end FY2025, retained earnings turned positive for the first time at +$288M, and total equity stands at $1.35B with only $35M of goodwill on the balance sheet.

The decline in current and quick ratios from 5x to 2.6x is a function of growing deferred-revenue balances (Super subscriptions sold but not yet recognized), not balance-sheet weakness — they remain firmly above 2x. Interest expense is immaterial. The balance sheet gives management complete strategic flexibility: a year of negative FCF could be absorbed without raising capital.

Returns, Reinvestment, and Capital Allocation

Returns on capital crossed into structural-compounder territory in FY2025. Return on invested capital reached 52%, return on equity 38%, and return on assets 19%. These would be world-class for any business; for one that was burning cash three years ago, they are an unusual signal of operating leverage finally arriving.

The bulk of capital "spent" by Duolingo is stock-based compensation, not cash. Buybacks have been minimal and largely offset employee-withholding mechanics. Diluted share count has crept from 39.5M (FY2022) to 48.3M (FY2025) — a roughly 7% increase over three years, or ~2.4% per year, which is at the lower end of what large-cap software peers absorb but is real dilution that the FCF-per-share figure has to outrun.

The verdict on capital allocation: management is reinvesting almost everything operating cash flow generates back into R&D and content (AI tutoring, new courses, the English Test). With ROIC over 50%, that is the right call. The open question is whether ROIC stays high once growth normalizes — historically, software ROIC compresses as growth slows.

Segment and Unit Economics

Duolingo does not report multiple operating segments in its public filings; the company operates as a single reportable segment with revenue split between subscriptions (~80%+ of revenue), advertising (low-double-digit %), Duolingo English Test, and other in-app purchases. Geographic detail is also limited in the financial statements. The most useful unit-economic disclosure management provides — and the lever the stock now trades on — is the relationship between Daily Active Users, Monthly Active Users, Paid Subscribers, and Bookings.

Public disclosure summarized from FY2024 and FY2025 shareholder letters:

Bookings (cash collected for subscriptions, recognized over the subscription term) is the leading indicator analysts now anchor on. The gap between resilient DAU growth (~21%) and slowing bookings growth (~10.5% guide for 2026) is the central debate: is this AI-driven engagement substitution that will eventually monetize, or a structural ceiling on how much language learners will pay?

Valuation and Market Expectations

The stock traded between $87 and $540 over the last 52 weeks — a 6x range. As of May 18, 2026 at $113.24, market cap is ~$5.28B, enterprise value ~$4.23B after netting $1.05B of net cash.

The valuation reset is real: EV/Sales went from 18.4x at the FY2024 close to ~3.8x today, and on a trailing P/E basis Duolingo went from 648x (FY2023, when GAAP net income was just $16M) to 173x (FY2024) to 20.5x (FY2025) to 17x on forward consensus EPS — a multiple that almost no one would have written down in early 2025. Two interpretations:

Bear: The 27% Q1 revenue growth plus 10.5% bookings guide imply the long-term steady-state growth rate is mid-teens, not 30%+. At that growth level a mid-teens P/E is fair, not cheap.

Bull: The deceleration is a deliberate, management-controlled investment cycle (AI tutoring rollout, DAU push), not a competitive break. Pretax earnings of $182M FY2025 plus continued operating leverage suggests an underlying earnings power closer to $250-300M in 2026-2027, putting the true forward P/E in the 18-22x range — reasonable for a 15%+ grower with 35% FCF margins.

Consensus on Bloomberg-style trackers shows analyst targets clustering between $90 and $275, a wide spread reflecting genuine disagreement on whether 2026 marks a strategic pause or a structural deceleration. Recent cuts (JP Morgan to $95, Morgan Stanley to $95, Evercore to $97, Citi to $101) cluster well below the older $250-$300 prints from 2025.

Peer Financial Comparison

Duolingo is, by quite a margin, the most profitable of the consumer-engagement set on both operating margin and FCF margin, with ROIC that is the highest in the table. Yet on EV/Sales it sits between Stride (a slower-growth education services company) and Spotify (a comparable consumer-subscription brand). Roblox, with similar revenue growth and worse operating margin, trades at 11.4x EV/Sales versus DUOL's 3.8x — a gap explained by Roblox's larger TAM narrative and its much heavier SBC (23% of revenue dilutes future EPS far more aggressively than DUOL's 13%). Chegg is the cautionary tale: revenue down 39% year-over-year as generative AI cannibalized its homework-help product, and the stock at 0.1x EV/Sales. The market is currently pricing DUOL somewhere between "the next Spotify" and "the next Chegg," with weight shifting toward the latter after the May 2026 bookings guide.

What to Watch in the Financials

What the financials confirm: Duolingo is now a genuinely profitable, cash-generative consumer-subscription business with an unleveraged balance sheet, sector-leading FCF margins, and returns on capital that put it in the top decile of US software. The compounder thesis is no longer aspirational — FY2025 proved it on three out of four lines (gross margin held, operating margin expanded, cash flow scaled).

What the financials contradict: The narrative that growth is durable in the 30-40% range is breaking down. Q1 FY2026 revenue growth of 27% and bookings guide of 10.5% for the year are not consistent with the prior trajectory. Either bookings re-accelerate in 2H 2026 as the AI-tutoring features land, or the long-term steady-state growth rate is materially lower than recently assumed — in which case further multiple compression is the path of least resistance.

The first financial metric to watch is bookings growth — specifically, whether the FY2026 print exceeds the 10.5% management guided in May, and whether quarterly bookings re-accelerate in the back half of 2026 as new AI-tutoring features roll out. Revenue follows bookings by one to two quarters; analyst price targets follow bookings by about ten minutes.
