Quality

77

of 100 · stored research reading

Stored Quality research reads 77 of 100, an above-average reading in the covered universe. Some underlying measurements are stronger than others.

Quality research measures durability of the business itself from stored fundamentals: balance-sheet strength, profitability consistency and cash generation. It is a research reading, not a prediction of future returns.

How this is measured

Fundamental Momentum

Deteriorating

31

of 100 · stored research reading

Stored Fundamental Momentum research reads 31 of 100. Stored measurements classify recent reported fundamentals as deteriorating. This describes reported financial change already disclosed, with no forward-looking claim.

Fundamental Momentum research measures the direction of recently reported company fundamentals compared with the company's own history. It describes reported change, not future price movement.

How this is measured

Capital Returns

Weak

35

of 100 · stored research reading

Stored Capital Returns research reads 35 of 100, recorded as weak. No dividend is recorded for this company, so the reading rests on buybacks and dilution control. Share count has increased at about 4.6% a year in the stored window.

Capital Returns research measures how a company has actually returned cash to shareholders: dividend record, buyback effectiveness, dilution control and how those payments were funded.

What this company does

Our mission is to develop the best education in the world and make it universally available.

Although education can open the door to economic opportunity, it is also among the principal sources of inequality: the privileged can get the best education in the world, while those with fewer resources, especially in developing countries, may not be able to get even basic schooling. That is why we started Duolingo. We believe that everyone, regardless of how wealthy they are, should have access to high quality education. And today, the technology necessary to enable this is in the hands of billions of people, in the form of a smartphone. At Duolingo, we build products native to the smartphone—bite-sized, on-demand and engaging—to make learning accessible and effective, opening doors for everyone alike.

Duolingo is a technology company founded by two engineers, Luis von Ahn and Severin Hacker. Luis and Severin met at Carnegie Mellon University, where Luis was a professor in the Computer Science Department and Severin was his Ph.D. student. Luis, a MacArthur Fellow, grew up in Guatemala and witnessed firsthand the tremendous impact that access to high quality education can have on people’s lives. Luis and Severin bonded over the dream of building an intelligent learning system informed by massive amounts of user engagement data that could deliver superior learning outcomes.

Our team, which as of December 31, 2025, consisted of more than 900 passionate employees, including more than 430 engineers, aims to build the most sophisticated education platform in the world. We believe that by combining modern technology, the very best talent, and a mission-driven approach, we can create better learning experiences and meaningful improvements in efficacy. Our products are powered by sophisticated data analytics and AI and delivered with world-class art, animation, and design to make it easier for learners to stay motivated, master new material, and achieve their learning goals.
