A U.S. jury found Theranos founder Elizabeth Holmes guilty on Monday of conspiring to defraud investors in the blood-testing startup, convicting her on four of 11 counts.

Holmes was convicted on charges of defrauding three other investors, as well as conspiring to do so. She was acquitted on three counts of defrauding patients who paid for tests from Theranos, and a related conspiracy charge. The jury could not reach a decision on three counts related to individual investors.

Holmes, wearing a gray suit jacket, appeared poised after the verdict was read. A sentencing date was not immediately set.
