PART IItem1. Gibraltar Industries Limited(the \"Company\") It is a leading manufacturer and distributor of building products in residential, industrial, infrastructure, renewable energy and energy saving markets. Our business strategy focuses on significantly improving and accelerating the growth and financial return of the company. We try our best. in- Create sustainable value for our shareholdersterm. We believe that this can be achieved through the transformation of the company\'s portfolio and its financial results. Our business strategy has four key elements: operational excellence, product innovation, portfolio management, and acquisition as a strategic accelerator. Operational Excellence is the first pillar of our strategy. We focus on reducing complexity, adjusting costs and simplifying product delivery through 80/20 initiatives (“80/20”). 80/20 is the practice of focusing on our biggest and best opportunities (the “80”) And eliminate the complexity associated with less profit opportunities (the “20”). Perform 80/20 of our business, and The lining and market speed of the demand replenishment plan, as well as the outsourcing plan for the lower quantity of products we provide to our customers to provide the appropriate value proposition, we have and will continue to improve our profitability investment in inventory and fixed assets, as well as our level of service to our customers. Product innovation is the second strategic pillar. At the heart of innovation is the allocation of new and existing resources to opportunities that we believe will yield sustainable returns. Our focus is on driving top growth through new products and innovative products. We focus on products and technologies related to terminals. Users can stand out from our competition. Our trade focus program is designed to redistribute sales and new product development talent to specific end user groups in order to better understand their needs and the various market opportunities that may be offered. This effort is expected to generate ideas and opportunities for profitable growth. Our innovation focuses on our current end market, including postal and parcel products, residential air management, infrastructure, renewable energy and energy conservation. Depending on the demand for centralized mail and parcel delivery systems, these respective markets are expected to grow, including solutions for the last 3 tables of delivery content; House with zero carbon footprint; Energy sources that do not rely on fossil fuels, as well as growing demand for locally grown agricultural products. The third pillar of our strategy is portfolio management, which is a natural aid to the 80/20 program. Using the 80/20 process, we conduct a strategic review of our customers and end markets and allocate leadership time, capital and resources to the highest levels -- Potential platforms and businesses. As a result, we sell and spin off businesses and product lines that help companies achieve higher ROI. We believe that portfolio management is an ongoing process that will remain an important part of our strategy as we seek to improve Gibraltar\'s long-term strategy Financial performance. The fourth pillar of our strategy is acquisition. We have targeted four key markets where we can make strategic acquisitions through the company\'s existing platforms. Target markets include: Postal, parcel and warehousing solutions; infrastructure; Air management in residential areas; Renewable energy and energy saving. These platforms are in large markets where potential trends in customer convenience and security, energy It is more and more important to save and save resources. term demand. We believe that these markets also offer a higher return on our investments than in the past. Acquisition of rough brother Manufacturing Co. , Ltd. RBI Solar , And the Nexus Corporation, which was collectively referred to as \"RBI\" in June 2015 (\"Nexus\") October 2016 February 2017 of package concierge desk recently a is August 2018 of solarbos this is the fourth pillar strategy of direct results. We also consider the business outside of these four markets, because we are constantly looking for opportunities to expand our business in large markets in the foreseeable future as demand is expected to grow, with our manufacturing expertise, 80/20 processes and sourcing synergies, we can add value here.
