This document analyzes AT&T's strategy using Porter's Five Forces analysis and a PESTEL analysis. It finds that the threats of new entrants and substitute products are high for AT&T due to capital costs, market competition, and price wars between providers. However, the bargaining power of suppliers is low. It also examines AT&T's value chain, core competencies, competitive advantages in services, and corporate strategy of vertical integration. Recommendations include vertically integrating security platforms, expanding IP services, and unifying wireline and wireless offerings.
