Group 3: PBMs Under Scrutiny - PBMs are facing increased criticism for contributing to rising drug prices, making them targets for reform efforts [7]. - Despite potential challenges for Express Scripts, Cigna's overall business is considered robust enough to withstand the impact of a weakened PBM segment [8].
