Zynex (ZYXI.Q) Stock Analysis & Winston Score

Zynex Medical makes medical devices that help people manage pain without surgery or opioid drugs. Its main product is a small electrical device called a TENS unit, which sends gentle pulses through the skin to block pain signals. The company sells mostly to patients recovering from injuries or surgeries, and doctors and physical therapists write the prescriptions. Zynex makes most of its money by billing insurance companies for its devices and the supplies patients need to keep using them, like electrodes and cables. It operates almost entirely in the United States and is a smaller company competing against larger medical device makers. The recurring supply revenue gives it a somewhat steady income stream, but its biggest risk is dependence on insurance reimbursement rates — if insurers cut what they pay or tighten coverage rules, revenue can drop quickly.
