Abbott Laboratories reported fourth quarter sales below expectations before the market opened on Jan. 22, sending the stock down nearly 12% from the prior day's closing. The biggest hits came from contraction in the nutrition group along with continued disruption in the diagnostics unit from volume-based procurement in China. Medical devices suffered from market share loss in electrophysiology and slower than expected uptake of continuous glucose monitors. The pharma group performed as anticipated, posting 7% growth.

Over the last year, diabetes technology saw significant changes, including the acceleration of patch pumps, ever-smaller continuous glucose monitors (CGM), implanted CGMs and increased interest in devices that measure additional chemicals in blood without needles.

The U.S. Centers for Medicare & Medicaid Services has posted the home health final rule for calendar year 2026 and has established a framework for competitive bidding for products such as continuous glucose monitors, a move that is struggling to find support among stakeholders.
