    Attronica Financial Planning & Analysis and Private Company Valuation Externship

    A 40-year-old, $80M family-owned IT firm is preparing to sell — and they need real FP&A work to back it: clean financials, a defensible forecast, and a valuation. Organize the books, model the forecast, and deliver a valuation that lands on the CEO's desk and on a buyer's table.

Overview

The work reviewed and reconciled Attronica's historical financial statements, constructed a multi-year forecast model, and produced a valuation using standard private-company approaches. Deliverables included cleaned books, scenario-based forecasts, and a valuation report suitable for review by company leadership.
