In January 2014, Perion took over Conduit's ClientConnect business in an all-stock transaction valued at $660 million. Later, in June 2014, Perion acquired San Francisco-based Grow Mobile as it repositioned itself to emphasize business-to-business services. After the acquisition, Grow Mobile was integrated into Perion Lightspeed, a platform that serves the advertising requirements of mobile app developers.

In September 2016, Perion announced that Mandelbaum would step down, and in January 2017 it named Doron Gerstel, a former chief executive of Zend Technologies and Panaya, as CEO, effective April 2017. Under his leadership, Perion took initiatives to minimize the company's debt and enhance its "operational efficiency". This period also saw the company broaden its reach into the digital television advertising sector.

In June 2024, Perion announced significant layoffs as part of a cost-cutting initiative. The decision came after Microsoft's further actions to completely remove several advertisers from its Bing network, which severely harmed Perion's revenues. As a result, Perion decided to eliminate 35 jobs, primarily within its search division in Israel. This reduction represented 15% of the company's Israeli workforce, which numbered 230 employees out of a total of 650 globally.
