Thryv Holdings Inc (NASDAQ: THRY), a leading provider of sales and marketing software for small businesses, saw its stock soar 12.41% on Thursday as the company reported impressive fourth-quarter 2024 results, driven by robust growth in its SaaS business segment.

The Thryv SaaS platform, which offers AI-supported marketing and business automation tools, witnessed a 41% year-over-year increase in total SaaS revenue during the fourth quarter.

This margin expansion highlights Thryv's focus on driving profitability and operational efficiency within its fast-growing SaaS business.

For the full year 2024, Thryv reported a 30% year-over-year increase in total SaaS revenue, reaching $343.5 million. The company's SaaS adjusted EBITDA margin for the full year stood at 12%, reflecting the ongoing scale benefits and operating leverage in the segment.
