Company history.

SiamEast Solutions Company Limited (Public Company) (“the Company” or “SE”) (formerly known as “Siam Rajathanee (Eastern) Limited”) was established on August 13, 1993 with an initial registered capital of 2.00 million baht. The company’s main objective was to procure and distribute industrial products in the categories of pump systems covering various applications including water, liquids, slurries, and related equipment to industrial factories in Rayong province and nearby provinces in the eastern region of Thailand.

The company started its operations in 1984 under the name Engineering Products Limited (“Engineering Products”) with the aim of providing engineering design services and distributing industrial pump systems and associated equipment to industrial factories. The company’s expansion was driven by the economic growth following the government’s strategies, particularly in the Eastern Seaboard project in the eastern region of Thailand, which is considered a strategic area for transportation and industrial investment. This resulted in a significant increase in the number of industrial factories in the Map Ta Phut Industrial Estate, Rayong province. Due to this growth, in 1993 , the management decided to separate the business operations from Engineering Products and establish Siam Rajathanee (Eastern) Limited, with the main objective of procuring and distributing industrial products to industrial factories.

The company focused on the primary customer group consisting of industrial factories located in various industrial estates in Rayong province and nearby provinces in the eastern region of Thailand. With good relationships and access to customers, the company expanded its product procurement and distribution to include products in the categories of process management and piping systems, as well as innovative materials and related services to meet the diverse needs of industrial factories.

With the vision of expanding the procurement and distribution of industrial products and services to cover customers in all industries nationwide, in 2009, the company opened an office in Bangkok and expanded its sales engineering team to offer and distribute products in all three product groups to customers in Bangkok metropolitan area, suburbs, and regions across Thailand, as well as opportunities to export industrial products to customers abroad.

The company operates under the concept of being an Industrial Equipment Solution Provider, meaning that it is a comprehensive provider of industrial products and services. This includes quality product selection, presenting alternatives and new innovations, and providing sincere service to ensure maximum customer satisfaction. Additionally, the company offers engineering services related to industrial products, after-sales service, and maintenance services to increase operational efficiency and extend the lifespan of products.

On March 18, 2016, the company transformed into a public company and changed its name to Siam East Solutions Company Limited (Public Company), with a registered capital of 120,000,000 baht, consisting of 240,000,000 ordinary shares with a par value of 0.50 baht per share. Of this, 90,000,000 baht has been paid for the remaining ordinary shares. The company issued an additional 60,000,000 ordinary shares to support its initial public offering (IPO) at a price of 2.45 baht per share, amounting to 147,000,000 baht. Trading commenced on February 14, 2017.

Currently, the company has a registered capital of 339,727,380 baht, with 339,725,166.50 baht paid-up capital.
