Sensitivity & Scenario Analysis

The sensitivity and scenario analysis — base, upside and downside cases across customer growth, credit losses and cost assumptions.

The Company has stress-tested the financial model against the
principal value drivers — net interest margin, cost-to-income ratio,
customer growth pace, and credit losses. The results are consistent with
the Company’s view that the business model is robust across a wide range
of plausible outcomes.

16.2 Three-Scenario Analysis

Metric (Year 5) Bear Case Base Case Bull Case
Total Customers (m) 4.20 6.50 8.20
Total Revenue (ZAR m) 5,400 8,700 11,800
Cost-to-Income Ratio 47% 38% 33%
NPL Ratio 8.5% 6.4% 5.5%
Net Profit (ZAR m) 850 2,340 3,800
ROE 14.5% 31.8% 44.0%
Equity IRR (5-Yr) 16% 28% 39%
Year-5 Implied Valuation ZAR 12.0bn ZAR 21.5bn ZAR 33.0bn

16.3 Scenario Drivers

The bear case assumes: customer acquisition tracks 70% of plan; CPA
inflation of 25%; NIM compression of 75 bps below plan; and a stressed
credit loss path peaking at 9.5%. Despite these assumptions, the
business remains economically viable and continues to deliver positive
returns. The bull case assumes: 30% faster customer acquisition; NIM 50
bps above plan; cost discipline 5 percentage points better than base;
and benign credit conditions.

16.4 Stress Test — SARB Macro Stress

The Company has applied a stylised version of the SARB Macro Stress
Test scenario (severe recession, repo rate +400bps, currency
depreciation, employment shock). Under this stress, the CET1 ratio
bottoms at 11.6% in Year 3 — comfortably above the 8.0% regulatory
minimum and the SARB-prescribed Capital Conservation Buffer.
