Appendix A: Detailed Sensitivity Analysis
The sensitivity analysis examines the impact of key variables on the project’s equity IRR, holding all other variables constant at base-case levels. The analysis confirms that wheat price and yield are the most significant drivers of project returns, followed by input costs and exchange rate movements.

Appendix C: South African Wheat Industry Data
This appendix provides supplementary industry statistics sourced from SAGIS, NAMC, USDA-FAS, and Agbiz. Key data points include historical wheat production and area planted statistics (2015–2026), import volumes by source country, SAFEX wheat price history, and provincial production breakdowns. These data underpin the market analysis and financial assumptions presented in the main body of this business plan.
