The top legal officer at Five9 sold nearly 30,000 shares of the company's stock in May, marking the largest single sale by that executive on record, according to a SEC Form 4 filing reported by Yahoo Finance.
Tiffany N. Meriweather, Chief Administrative and Legal Officer at Five9, sold 29,817 shares in open-market transactions on May 13 and May 14, 2026. The shares were sold at a weighted average price of around $21.05 per share, roughly in line with the May 14 market close.
The sale was the largest single direct sale Meriweather has made at Five9 to date. It surpassed her previous high of 7,861 shares sold in September 2025 and exceeded the average of 12,618 shares per sale across four historical sell events. The transaction accounted for 9.6 percent of her direct holdings at the time, reducing her direct ownership from 311,115 shares to 281,298 shares. No indirect or derivative holdings were reported after the sale.
The timing of the sale came after Five9 shares had declined 22.40 percent over the prior year. Shares had also rebounded from a 52-week low of $13.29 reached in April 2026, suggesting Meriweather was selling into a partial recovery from that low point.
Five9 operates a cloud-based contact center software platform that supports voice, video, chat, email, social media, and API integrations. The platform includes natural language processing and automatic speech recognition tools. The company generates revenue through recurring subscriptions and usage-based fees and serves enterprise and mid-market customers across financial services, healthcare, technology, education, and business process outsourcing.
The elevated size of the transaction, relative to Meriweather's historical selling pattern, follows a period of smaller, incremental sales. Analysts who track insider activity note this shift toward larger, less frequent trades as direct holdings decrease. Insider sales do not necessarily signal a negative outlook, as executives sell shares for a variety of personal financial reasons, but the scale of this transaction relative to prior sales drew attention.
Five9's next filing deadlines and earnings reports will be watched for any additional context on the company's financial direction.
