Rentokil Initial shares plummeted by up to 21% following a profit warning due to slower-than-expected sales in North America and adverse currency impacts. The world's largest pest control company, which generates 60% of its revenue from North America, revealed that sluggish growth and over-resourcing during peak season contributed to a projected £80 million hit to full-year earnings. The company also anticipates lower organic revenue growth of about 1% in North America for the second half of 2024. In response, Rentokil plans to cut jobs to manage cost overruns. Despite recent positive momentum in the second quarter, sales in July and August fell short of expectations, exacerbating the financial strain. Activist investor Nelson Peltz's Trian Partners, which holds a significant stake, may push for strategic changes to improve shareholder value.
