Shares of Accel Entertainment Inc (ACEL) tumbled 6.30% in after-hours trading on Tuesday, following the release of the company's second-quarter financial results and news of CEO Andrew Rubenstein disposing of common shares.

The gaming terminal operator reported Q2 revenue of $335.909 million, with a net income of $7.262 million. The company's operating income stood at $26.874 million, while adjusted EBITDA came in at $53.18 million. Adjusted net income for the quarter was $22.491 million. While these figures provide a snapshot of the company's performance, the market's negative reaction suggests that the results may have fallen short of investor expectations or shown signs of slowing growth compared to previous quarters.

Adding to investor concerns, a separate filing revealed that CEO and President Andrew H. Rubenstein had disposed of an undisclosed number of common shares. This move by a key insider could be interpreted as a lack of confidence in the company's near-term prospects, potentially contributing to the stock's after-hours decline. Investors will likely be watching closely for any further explanations from the company regarding both the financial results and the reasons behind the CEO's share disposal.
