Evidence-gathering procedures included but were not limited to:

• Review of General Dynamics data and information systems and methodology for collection, aggregation,
analysis and review of information used to determine GHG emissions; and

Verification Opinion:
Based on the process and procedures conducted, there is no evidence that the GHG emissions statement shown
