Start this off. With a bang, NAPCO Security stock surged 19.22% in pre-open

On Monday, NAPCO Security stock surged 19.22% in pre-open trading after the company reported fiscal fourth-quarter and full-year 2026 financial results before the market open.

The company posted a quarterly record $55.8 million in net revenue — a 10.0% increase compared to the same period a year earlier and a substantial beat against analyst consensus estimates of roughly $53.6 million.

The strong top-line performance underscored a meaningful acceleration in the company’s growth trajectory and caught the market’s attention given that analysts had been expecting a more modest 3–4% revenue expansion heading into the print.

A key driver behind the revenue strength is the company’s high-margin recurring service revenue stream, which carries gross margins of approximately 91% and has been compounding at double-digit rates, now accounting for nearly half of total sales.
