You could use FLAG_ACTIVITY_CLEAR_TOP.

From documentation

If set, and the activity being launched is already running in the current task, then instead of launching a new instance of that activity, all of the other activities on top of it will be closed and this Intent will be delivered to the (now on top) old activity as a new Intent.

For your example, if you have ActivityA, ActivityB, ActivityC, you could return to ActivityA from ActivityC with

Intent intent = new Intent(getContext(), ActivityA.class);
intent.setFlags(Activity.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtras(<DATA_NAME>, <DATA_VALUE>);

You activity will be launched with this new intent containing your data. Activity B and C will be finished.
