Duolingo

Duolingo, listed on the Nasdaq under the mnemonic DUOL, is a technology company specializing in online language learning. It offers a mobile platform and a digital exam to assess language skills. Its freemium model allows free access to the application, with premium options available for a fee. Products include the Duolingo app, Super Duolingo, Duolingo Max, and the Duolingo English Test. The app offers courses in over 40 languages, attracting a broad user base. Duolingo stands out for its strong growth. In 2023, the company recorded sales of USD 531 million, up from USD 369 million in 2022. Forecasts for 2024 and 2025 indicate continued growth, with estimated revenues reaching USD 736 million and USD 950 million respectively. The company has also improved its profitability, posting an EBITDA of USD 93.7 million in 2023, compared with USD 15.5 million in 2022. Duolingo's strategy is based on continuous innovation, notably with the introduction of features based on artificial intelligence. These innovations aim to enrich the user experience and increase engagement. The company recently announced AI-based language learning tools, including video calling and immersive adventures. Duolingo has solid fundamentals, with a robust financial position and significant investment capacity. However, the company's valuation is high, with an expected PER of 154 for the current financial year. Duolingo is a fast-growing and leading player in the online language learning market.

Rocket Lab USA

Rocket Lab USA (NASDAQ: RKLB) is a launch services and space systems company, positioning itself as a key player in the aerospace and defense industry. The company designs and manufactures rockets, spacecraft and related components, offering complete solutions for access to space. With a significant market share in the United States (75.53% of sales), Rocket Lab stands out for its ability to deliver fast, reliable launches, as demonstrated by its recent "Changes In Latitudes, Changes In Attitudes" mission. Rocket Lab is showing impressive sales growth, from USD 62.2 million in 2021 to USD 245 million in 2023, with forecasts of USD 886.6 million by 2026. This growth is underpinned by a strategy of continued expansion, illustrated by recent contracts with NASA for studies on the return of Martian samples, and collaborations with Varda Space Industries for manufacturing missions in space. However, the company faces financial challenges, including low profitability and high debt-to-EBITDA ratios. Margins remain fragile, and the current valuation is considered high relative to its size. Despite these challenges, analysts remain optimistic about the company's future growth, mostly recommending a Buy or Overweight rating on the stock. The US company offers significant growth potential in the space sector, supported by technological innovations and strategic partnerships.
