Shares of SoundThinking slid after the company cut its full-year guidance, citing a challenging macroeconomic and procurement environment, and reported second-quarter results below Wall Street expectations.

The stock fell 18%, to $6.80, in after-hours trading Thursday. It closed up 1.5% at $8.27, and has risen 3% this year.

The maker of public-safety technologies including ShotSpotter said it now expects full-year revenue between $99 million and $100 million, compared with previous guidance for revenue between $109 million and $111 million.

Analysts polled by FactSet currently expect $109.2 million in full-year revenue.

SoundThinking also cut its full-year adjusted earnings before interest, taxes, depreciation, and amortization margin guidance to between 8% and 9%, down from a range of 16% to 18%. Annual recurring revenue at the beginning of 2027 is now forecast at more than $100 million, down from previous guidance of $110 million.

"Given our softer-than-expected first-half results and the timing of certain customer and procurement decisions, we believe it is prudent to revise our 2026 outlook while remaining focused on disciplined execution," Chief Executive Officer Ralph Clark said.

Clark said he believes demand is expanding and the underlying health of the business remains strong, despite underwhelming second-quarter results.

The company reported a second-quarter loss of $4.8 million, or 37 cents a share, in the quarter ended June 30. That compares with a loss of $3.1 million, or 24 cents a share, a year earlier. Analysts were expecting a loss of 25 cents a share.

Revenue fell to $23.9 million from $25.9 million. Analysts were expecting $25.8 million in revenue.
