APEX-Agents task World 246_MM_04 in AI Agents for Tax Due Diligence. Compare dual-harness agent runs across models, scores, and public traces.
Task prompt
What the agent was asked to do
Calculate the unlevered beta for Haleon (HLN) using Total Debt and Market Capitalization as of the end of FY2024. Assume 0.227 levered beta for HLN and a 21% Tax rate. Using the unlevered beta for HLN computed above, and the debt and equity values in the model, re-leverage the Beta for Kenvue and update the WACC with the new Re-levered Beta. Reply back with a message, giving the following results: - the New WACC - the New Implied Share Price. - the Variance in $ for Share Price (New-Original) Round all outputs to two decimal places.
