## Edgarette's reading

Exposure: revenue $35.7M (FY2025), total debt $53.5M. Experience: revenue down 0.5% on the year, up 41.2% a year over 4 years; operating margin -433.5%, down from -24.9%. Soundness: equity 54.2% of assets, return on equity -169.7%. Credibility: four or more audited years, reasonable weight. Range: 80% of past cases like this landed between $9.5M and $134.5M next year (method v4.1: its own 4-year record of growth weighed at 50% against under $50M filers; across 2019–2025, 69.0% landed inside, 83.4% on the one year the method never saw). In a shock year the stress range is $7.9M to $162.4M. A statistical range, not company guidance. Against peers (36 filers, $50M+ revenue, finance services): operating margin -433.5% against a -6.4% median; growth -0.5% against 16.8%.
