In a globalized economy in which the reproduction of capital is increasingly taking place on a global scale, there are numerous subjects (funds, foundations, individuals) who explore beyond the borders of their home countries. No, the most important are the holders of foreign direct investment by multinational companies. Market expansion is a condition for the survival and growth of multinational companies. No, for many countries, especially low-income countries, the ability to effectively engage in global value values is a key condition for development. This presupposes the ability to access global value chains, to successfully compete and “capture profits” in terms of national economic development, to strengthen skills and to create more and better jobs to reduce unemployment and poverty. Global value chains are a consequence of globalization, as well as the conquest of new markets by multinational companies, which the issues in this paper seek to point out. This paper points out the importance and specifics of multinational companies operating in global value chains through network subsidiaries, contractors or independent suppliers, and analyzes the vertical integration of such companies into global chain values on the example of the successful oil multinational company Saudi Aramco. Multinational oil companies are one of the most successful companies, as they generate the highest revenues from their activities, which is why it seemed interesting to present the multinational oil giant Saudi Aramco by conducting an advantage analysis by choosing vertical integration strategy, which achieves competitive advantage in the market. Based on all the facts, it can be concluded that the company chooses the right strategies in this case on the example of Saudi Aramco, vertical integration will significantly strengthen the competitive position and produce sufficient cost savings.
