Key Terms

at-the-market equity offering program financial

A program that lets a company sell newly issued shares directly into the open market at whatever the current trading price is, usually through a broker, and do so gradually over time instead of all at once. Investors care because it can dilute existing ownership and put steady selling pressure on the stock price, while giving the company a flexible, on-demand way to raise cash — like adding small amounts of water to a pool rather than dumping in a bucket.

nanosecond pulsed field ablation medical

Nanosecond pulsed field ablation is a medical technique that uses extremely short, high‑voltage electrical pulses—each lasting billionths of a second—to selectively disable small areas of tissue, most often to treat irregular heart rhythms. Like a precise, ultra‑brief electric zap that spares surrounding structures, it matters to investors because it can shorten procedure time, reduce complications and recovery, and therefore reshape demand, pricing and adoption for cardiac ablation devices and related services.
