K osmos now has two locations in the U.S. The company’s corporate headquarters, with approximately 210 employees, remains in Dallas. Our Gulf of Mexico business unit is managed from Houston, which is home to approximately 50 employees. In 2019, Kosmos plans to continue infill drilling on existing fields in the U.S. Gulf of Mexico, drilling infrastructure-led exploration targets, and progressing the development of previous discoveries via subsea tieback to existing infrastructure. As part of our new operations in the Gulf of Mexico, we are beginning a process of stakeholder outreach to establish relationships in the areas onshore from our operations. While in the early stages of planning, this outreach is expected to include stakeholders at the state and local levels in states along the U.S. Gulf Coast, particularly Texas and Louisiana. Similarly, in 2019, we will be taking a fresh look at our social investment approach in the Gulf of Mexico in light of our larger operational footprint. POSITIVE IMPACTS In 2018, Kosmos continued to support its primary social investment partners in the Dallas-Fort Worth area through a combination of multi-year engagements and one-time support. Our U.S.-focused social investment at the corporate level has historically centered on improving the quality of STEM education and building cross- cultural understanding. Capacity Building in STEM Education Each day at Kosmos, we use the fundamentals of science, technology, engineering, and math (STEM) to do our jobs. We interpret seismic data to identify potential oil and gas deposits. We plan deepwater drilling operations targeting prospects located more than three miles below the ocean floor. We study the rocks we bring to the surface to better understand where oil and gas might be found. Being at the forefront of science and technology is how we play our part in helping to meet the world’s energy needs and how we create value for our shareholders. The shortage of people with training in the STEM disciplines poses a potential long-term threat to many businesses, including our own. In 2015, Kosmos announced a partnership with the Perot Museum of Nature and Science to face this challenge head-on by helping Dallas school teachers develop their ability to train and inspire young people in the STEM disciplines. The Kosmos Energy STEM Teacher Institute is an innovative program offered through the Perot Museum to improve the quality of formal science instruction for participating kindergarten through 12th grade teachers, and increase interest and engagement among their students in STEM subjects. Through this program, teachers In late 2018, Kosmos entered the U.S. Gulf of Mexico through the acquisition of Deep Gulf Energy, a leading Gulf of Mexico operator. In the transaction, Kosmos acquired interests in 12 producing fields across the East Breaks, Garden Banks, Green Canyon and Mississippi Canyon areas, as well as a portfolio of exploration prospects suitable for both infrastructure-led and frontier exploration. 27 The Kosmos Energy STEM Teacher Institute at the Perot Museum of Nature and Science benefited about 4,800 students during the 2017-2018 school year, with participating teachers reporting increased confidence and creativity in teaching the STEM disciplines.
