Why most employers are sticking with Big 3 PBMs over alternatives

- Most employers still use the Big 3 PBMs despite concerns about transparency and costs. 
-Alternative PBMs offer more transparent pricing and potential savings. 
-Employers hesitate to switch because it can disrupt employee benefits and requires significant effort. 
-The Big 3 remain dominant due to their scale, networks, and established relationships. 
-Interest in alternatives is growing, but adoption remains relatively slow.
