HAL Holding has signed a deal to buy a 25 percent share in Grupo Optico Lux, a chain of 69 optical stores based in Mexico City. The deal should close in the second quarter of 2010. Hal has an option of buying another 45 percent of the business at a later stage. Grupo Optico Lux reported sales of about €37 million last year. The acquisition expands Hal's presence in Mexico after it bought Sunglass Island and Island Optical, with a total of 42 stores, from Safilo last year.
