Convert the annotation to point features, and label the points using the TextString field in ArcMap
  1. In ArcGIS Pro, convert the annotation to point features using the Feature To Point tool.
    Note:
    The Feature To Point tool is only available with an ArcGIS Desktop Advanced license.
    1. In the Geoprocessing pane, navigate to Toolboxes > Data Management ToolsFeatures > Feature To Point.
    2. In the Feature To Point pane, select the annotation feature class as the Input Features.
    3. Set a name and location for the Output Feature Class.
    4. Click Run. The annotations are displayed in the TextString field in the point feature class attribute table as shown in the image below.

  2. In ArcMap, add the point feature class to the map, and label the features using the TextString field.
    1. Click the Add Data icon, and browse to the point feature class converted in Step 1.
    2. In the Labeling toolbar, click Label Manager.
    3. In the Label Manager dialog box, check the check box for the point feature class in the Label Classes section, and select TextString for the Label Field.
