The prospective buyer of US smoothie company Jamba Juice has said the two companies have allowed themselves more time to back out of the deal.

Florida-based Services Acquisition Corp. International (SACI) said the deadline for approving the deal had been pushed back a month to 15 September.

In addition, SACI announced that investors have been given more time to approve the deal, with a deadline also set for 15 September.

Steve Berrard and Paul Clayton, CEOs of SACI and Jamba Juice respectively, issued a joint statement. They said the moves "reflect the continued interest of all parties in finalising this business combination in a timely manner and that both companies remain enthusiastic about the prospects of the combined company".

The statement also said that the two men had been working over the past few months assembling a proposed board of directors for Jamba Juice under its new ownership.
