TSE Company Profile

Trinseo S.A. is a public limited liability company (société anonyme) formed in 2010 and existing under the laws of Luxembourg. Prior to our formation, our business was wholly owned by Dow. On June 17, 2010, investment funds advised or managed by affiliates of Bain Capital acquired our business and Dow Europe. During 2016, Bain Capital divested its entire ownership in the Company in a series of secondary offerings to the market.

We are a leading global materials company engaged in the manufacture and marketing of synthetic rubber, latex binders, and plastics, including various specialty and technologically differentiated products. We have leading market positions in many of the markets in which we compete. Our products that are incorporated into a wide range of our customers’ products throughout the world, including tires and other products for automotive applications, carpet and artificial turf backing, coated paper, specialty paper and packaging board, food packaging, appliances, medical devices, consumer electronics and construction applications, among others. We have long-standing relationships with a diverse base of global customers, many of whom are leaders in their markets and rely on us for formulation, technological differentiation, and compounding expertise to find sustainable solutions for their businesses. Many of our products represent only a small portion of a finished product’s production costs, but provide critical functionality to the finished product and are often specifically developed to customer specifications. Therefore, we seek to regularly develop new and improved products and processes, supported by our intellectual property portfolio, designed to enhance our customers’ product offerings. We believe these product traits result in substantial customer loyalty for our products.

We have significant manufacturing and production operations around the world, which allow us to serve our global customer base. Our production facilities included 30 manufacturing plants (which included a total of 75 production units) at 23 sites across 12 countries, including joint ventures and contract manufacturers. Additionally, as of December 31, 2016, we operated 10 research and development (“R&D”) facilities globally, including mini plants, development centers and pilot coaters, which we believe are critical to our global presence and innovation capabilities. Our significant global operations provide geographic revenue diversity, and diversity in end markets for our products.

We operate our business in two divisions: Performance Materials and Basic Plastics & Feedstocks. Our two divisions are of similar size in terms of sales, but have different margin profiles, different strategic focus, different value drivers and different operating requirements. By organizing in this way, we believe that we can best manage and operate the Company, focusing on accelerating the growth of our Performance Materials division and improving the profitability of our Basic Plastics & Feedstocks division.

Our chief executive officer, who is our chief operating decision maker, previously managed our operations under four reporting segments: Latex, Synthetic Rubber, Performance Plastics, and Basic Plastics & Feedstocks. Effective October 1, 2016, the Company realigned its reporting segments in order to provide increased clarity and understanding around the drivers of profitability and cash flow in our business. First, the previous Basic Plastics & Feedstocks segment was split into three new segments: Basic Plastics, which includes polystyrene, copolymers, and polycarbonate; Feedstocks, which represents our styrene monomer business; and Americas Styrenics, which reflects the equity earnings from our 50%-owned styrenics joint venture. In addition, certain highly differentiated acrylonitrile-butadiene-styrene (or ABS) supplied into Performance Plastics markets, which was previously included in the results of Basic Plastics & Feedstocks, is now included in Performance Plastics. Finally, the Latex segment was renamed to Latex Binders.
