Analysis
This announcement underscores 51Talk’s emphasis on global visibility and social impact, showcasing its GreenTalk program and student participation at COP30 from regions like Saudi Arabia, the UAE, Türkiye, Thailand, and Vietnam. Investors may view this as brand-building rather than directly financial. In context of recent strong growth but ongoing losses and a new buyback, key metrics to watch remain revenue growth, margins, cash balance, and whether future updates link such initiatives to student acquisition and engagement.

24h Move is the share-price change in the day after each event; other market factors may also have contributed.
Pattern Detected
Over the last six months, several positive or neutral events (strong earnings, buyback, auditor change) often coincided with negative price reactions, suggesting a pattern of the stock selling off or underperforming around ostensibly favorable news.
Recent Company History
In the past six months, 51Talk reported strong Q2 and Q3 2025 growth, with rapidly rising revenues and active student numbers but ongoing operating and net losses. An US$10M share repurchase program was authorized on Dec 8, 2025, and the company appointed Ernst & Young LLP as auditor effective Sep 3, 2025. Despite these developments, several announcements, including earnings and the buyback, saw double-digit percentage declines within 24 hours, indicating frequent divergence between seemingly positive news and short-term price reactions.
Key Terms
biodiversity, sustainability, marine ecosystem
3 terms
biodiversitytechnical
"By observing biodiversity conservation efforts firsthand and engaging with local communities"
Biodiversity is the variety of living things — different species, genetic traits and natural habitats — that make ecosystems function. For investors it matters because healthy biodiversity supports predictable resources and services (like pollination, clean water and resilient supply chains); loss or damage can create regulatory, operational and reputational risks, and undermine long‑term returns. Think of it like diversity in a garden or a portfolio: more variety usually means greater stability and fewer single‑point failures.
sustainabilitytechnical
"a deeper, more personal understanding of sustainability beyond the classroom"
Sustainability is the practice of using resources in a way that meets current needs without compromising the ability of future generations to meet theirs. It involves balancing economic, environmental, and social factors to create long-term stability and well-being. For investors, sustainability matters because it can influence the resilience and long-term success of businesses and economies.
marine ecosystemtechnical
"proposed floating solar islands made from recycled materials, combining clean energy with marine ecosystem restoration"
A marine ecosystem is the interconnected community of living organisms—fish, plants, microbes—and their physical environment in oceans, seas and coastal waters, working together like the services and people that keep a city running. It matters to investors because the health and balance of this system directly affect industries such as fishing, aquaculture, shipping, tourism and offshore energy, influencing resource availability, operational costs, regulatory risk and long-term company value.
An online 1-on-1 English platform enabling children from the Middle East and Southeast Asia to speak at COP30
BELEM, Brazil, Dec. 18, 2025 /PRNewswire/ -- 51Talk, a global online 1-on-1 English learning platform for children, announced that young learners from its international community took part in a United Nations–aligned youth speaking initiative during COP30, held in Belém, Brazil from November 15 to 21, 2025.
Launched in 2023, the initiative has entered its third year, creating opportunities for children from Saudi Arabia, UAE, Turkey, Thailand, and Vietnam to share their perspectives on climate and environmental protection in English. Through speeches delivered on a UN-level international stage, participants brought local observations into a global conversation, highlighting how climate challenges are experienced—and addressed—by younger generations around the world.
As part of the COP30 experience, students also participated in rainforest exploration and local cultural activities in Brazil. By observing biodiversity conservation efforts firsthand and engaging with local communities, the learners gained a deeper, more personal understanding of sustainability beyond the classroom, connecting language learning with real-world global issues.
The program, titled GreenTalk: Speak for Future, reflects 51Talk's belief that language is not only a learning outcome, but also bridge to global participation. Through long-term 1-on-1 instruction, interactive speaking practice, and a curriculum designed to build expression step by step, the platform supports children as they progress from everyday conversation to structured storytelling and public speaking.
"We believe every child deserves the opportunity to speak to the world," said Jack Huang, CEO of 51Talk. "When children are given the right tools and guidance, they are capable of expressing thoughtful ideas and engaging meaningfully with global issues. Seeing our students speak on a United Nations climate stage is a powerful reminder of what education can unlock."
Young learners demonstrated strong growth in English communication and global perspective through 51Talk while taking part in COP30. From Saudi Arabia, Sheddi Alharthi and Abdulmohsen Alsherih stood out among over 2,000 applicants, speaking on protecting the endangered Arabian oryx and safeguarding coral reefs in the Red Sea. Vietnam's Le Bao Nhi overcame early pronunciation and confidence challenges to win the GreenTalk contest, sharing how plastic pollution on her local beach inspired clean-up efforts and everyday action. Representing the UAE, Khaseeba Omar Al Rumaithi proposed floating solar islands made from recycled materials, combining clean energy with marine ecosystem restoration. Türkiye's Osman Batu drew on personal observations—from wildfires to biodiversity loss—while Thailand's Wasuthida Ringkleun used the image of a sea turtle trapped in a ghost net to highlight marine plastic pollution, reflecting youth-driven environmental awareness and global engagement.
Across regions, the students' speeches demonstrated not only improving English proficiency, but also confidence, empathy, and the ability to connect local realities with global challenges.
By creating a platform for these young voices, 51Talk aims to show how online English education can prepare children to participate confidently in international dialogue—bridging cultures, perspectives, and generations through communication.
Founded in 2011, 51Talk is a global online 1-on-1 English education platform for children aged 3 to 15. The platform connects learners with certified foreign teachers through interactive lessons, structured curriculums, and personalized instruction designed to build practical speaking skills and confidence. To date, 51Talk has served more than 40 million learners across over 50 countries and regions.
