Reckitt $RKT.L, the manufacturer known for its well-established cleaning brands like Dettol and Lysol, has reported disappointing growth in net sales for the first quarter of the year. This underperformance, attributed to declining volumes in crucial markets in Europe and North America, has led to a notable drop in the company’s stock prices. Despite maintaining its sales growth expectations, Reckitt has acknowledged facing "more challenging macroeconomic prospects."
