Rentokil becomes target of Trian's investment.

• Trian, the investment firm led by Nelson Peltz, holds a top-10 stake in Rentokil, the parent company of Terminix, and aims to collaborate with management to boost shareholder value.
• In the past year, the value of Rentokil shares has decreased by over one-third due to the company's struggle with a weakening market.
• After selling its remaining stake in Walt Disney Company, Trian disposed of its stake in the company, and a few weeks later, the stake was sold.

A spokesperson for Nelson Peltz's Trian Partners revealed that they have accumulated a substantial share in Rentokil, the parent company of Terminix, and are now looking to communicate with leadership about ways to enhance shareholder value.

The pest-control giant's shares surged around 8% after hours on the news, increasing its market capitalization to $13.3 billion at Tuesday's close.

The spokesperson stated that Trian is a top-10 shareholder, meaning its stake is valued at more than $400 million or at least 3% of shares outstanding.

Rentokil, based in London, did not respond to CNBC's request for comment through a spokesperson.

Trian's Peltz has a wealth of experience with consumer-focused companies, having previously served on the boards of Heinz and other companies. Recent reports indicate that he has recently invested in Rentokil, following the disposal of his remaining stake in Disney.

Earlier this year, Peltz's campaign for board seats at the entertainment giant was unsuccessful.
