A hung jury leads to a mistrial. After a mistrial, the prosecution has the option of trying the case again, but it gets harder (you’ve got more time from the events, a more-tainted jury pool, etc.)
Also, if there are multiple charges, and the jury reaches a not guilty verdict on any charges, that may impact the ability to refile other charges, or make it harder to try them if they can be refiled, because any fact that the jury necessarily rejected in an acquittal is finally decided by that acquittal.
