The Livestrong Foundation's president, Doug Ulman, is scheduled to deliver what the organization describes as a "major 'State of the Foundation' speech" Thursday in Chicago.
The foundation released excerpts of Ulman's remarks in advance in which he says Livestrong's success "has never been based on one person" and that the group will "absolutely" survive.
Armstrong left the charity recently, saying he didn't want his association to damage the foundation's ability to raise money and continue its advocacy programs for cancer victims.
Originally called the Lance Armstrong Foundation, the cyclist created the charity a year after he was diagnosed with testicular cancer.
