Eli Lilly hiked its 2025 guidance and posted second-quarter earnings that topped estimates on strong demand for its blockbuster weight loss and diabetes drugs.

Texas Attorney General Ken Paxton has filed a lawsuit against Eli Lilly and Co. (NYSE:LLY), accusing the pharmaceutical giant of bribing medical providers to promote its most profitable drugs, including the widely used GLP-1 medications Mounjaro and Zepbound for diabetes and weight loss.

Lilly's weight-loss medications Mounjaro and Zepbound are gaining market share on Novo's Wegovy and Ozempic, but investors remain unconvinced.

Paxton's office said the company supplied free nurses to help care for patients who received its drugs, as well as administrative support services that helped providers process insurance claims.

Texas Attorney General Ken Paxton alleges that Eli Lilly bribed Texas medical providers to provide the company's drugs. Eli Lilly denies the claims.
