Hi @Anonymous User, thanks for posting your question here. Currently, we don't have labeling support for subscript and superscript. As an alternative, this sample shows some formatting options with multiple label classes: https://developers.arcgis.com/javascript/latest/sample-code/sandbox/?sample=labels-multiple-classes
