A letter to the Letone family | Joining hands to welcome the Year of the horse and write a new chapter of development

Dear Letone Family Members: Happy New Year!

Time flies, and a new year begins. As we bid farewell to the old year and welcome the new, we extend our sincere greetings and New Year's wishes to everyone with gratitude and anticipation! In the past year, we have worked hand in hand, striving forward and navigating the vibrant year of 2025 together. This year has had its surprises and its regrets, its gains and its growth. While there were no earth-shattering moments of glory, the steadfast and diligent efforts of every Letone employee have formed the cornerstone of the company's steady development, ensuring every step is solid and resolute.

Looking back on 2025, the external environment was complex and volatile. We rose to the challenge, forging ahead with determination. Overall performance remained stable under pressure, and we successfully navigated the challenges of tariff fluctuations. Our core business has continued to strengthen, with breakthroughs achieved in multiple R&D projects—new products such as nuclear power hoses, ultra-high pressure sterilizers, temperature isostatic pressing equipment, liquid cooling piping systems, API-17K series hoses, nylon recycling, sulfide microcapsules, masterbatch series, resin modified products, and HPP Fresh series have been launched successively, accumulating strong development momentum for the next two to three years.

Over the past year, the company's four major business segments—advanced polymer new materials, fluid piping, ultra-high pressure equipment, and application services—have shown initial results and are working synergistically to solidly fulfill the mission of "bringing fluid technology to benefit millions," pointing a clear direction for Letone's development.

Over the past year, we have continuously improved our project management partnership system, injecting talent vitality into transformation and upgrading, and creating a core engine driving Letone's progress. The company's development philosophy is also actively transforming: from focusing on profitability and projects to placing greater emphasis on social value and employee well-being. We have launched a series of care programs, advocating "love for yourself, love for your family, and love for everyone," promoting the common growth of society, enterprises, and individuals, and guiding everyone to participate in the comprehensive health cause of "eating healthily, regulating health, and managing health," injecting warm and lasting new momentum into the company's development.

2026 is the opening year of the national "15th Five-Year Plan" and a crucial first year of Letone's new development stage. We will continue to focus on the hard requirements of sustainable and high-quality development, strengthening our capabilities and ensuring long-term stability; at the same time, we will invest more resources to promote public health and a high-quality work-life balance, giving back to society with a righteous heart and mind.

In the new year, we will continue to adhere to the key principle of "increasing revenue and reducing expenditure," strengthening marketing, deepening quality and efficiency improvements, ensuring all employees practice thrift, resolutely eliminating waste, and deeply implementing the core values ​​of "customer-centricity, respect for employees, and reverence for products."

In the new year, we will strengthen talent and organizational development, accelerate the introduction and training of urgently needed talent, and continuously optimize the partnership-based operating model.

In the new year, we will actively promote capital operation and project investment to empower the company's high-quality development.

In the new year, we will also be actively promoting the "Eat Healthily, Adjust Healthily, Manage Health" campaign for all Letone family members, ensuring everyone truly experiences the benefits of a high-quality work and life.

In the new year, we will continue to improve our employee profit-sharing mechanism, enhance welfare benefits, raise dining standards, increase the variety of dishes, and improve service levels, continuously enhancing the happiness and sense of fulfillment of every family member.

The road ahead is long, but our original aspirations remain steadfast. In 2026, let us meet the challenges with even greater fighting spirit, and with more professional management and warmer service, become high-quality value creators and warm-hearted happiness builders!

Finally, I sincerely wish all Letone family members: a prosperous Year of the Horse, family happiness, good health, and all the best!

May the new year surpass the old; may this moment be worth a thousand words.

May we join hands, with one heart and one mind, to create a new era of brilliance for Letone!
