Hansen Natural Corporation has secured the presence of its Monster energy drink in the Carl's Jr and Hardee's fast food restaurants in the US.

CKE Restaurants, the parent company of Carl's Jr and Hardee's, confirmed yesterday (3 August) that it has partnered with Hansen Natural's Monster Beverage Company to offer Monster in its 3,000-plus restaurants across the country.

The agreement between CKE and Monster makes Carl's Jr and Hardee's the first major US quick-serve restaurants to offer Monster as a permanent menu item. More specific details behind the tie-up were not disclosed.

Carl's Jr is immediately offering Monster Energy drinks in all company and franchise units. Hardee's company-owned units will begin selling Monster Energy in mid-August, with franchised units joining later.

Headquartered in Carpinteria, California, CKE Restaurants, through its subsidiaries, has 3,133 franchised, licensed or company-operated restaurants in 42 states and in 14 countries, including 1,205 Carl's Jr restaurants and 1,915 Hardee's restaurants.

Hansen Natural will report its second quarter and half-year results on 5 August.
