Series C 409A: Enterprise-Grade Valuation

By Series C, your company is typically in the $50M–$200M ARR range, preparing for either a major growth phase or eventual IPO. The 409A valuation at this stage must reflect the full complexity of your equity structure and the rigor expected by institutional investors, Big 4 auditors, and potential acquirers.

Complex Equity Structure Analysis

After multiple funding rounds, your cap table includes numerous classes of preferred stock, each with its own liquidation preferences, participation rights, and conversion terms. The OPM must accurately model all of these:

Series Seed, A, B, and C preferred (each with distinct rights)
Participating vs. non-participating preferred
Multiple liquidation preference multipliers
Weighted-average anti-dilution provisions
Warrants and out-of-the-money options

Pre-IPO Benchmarking

For companies targeting an IPO in the next 12–24 months, the 409A provides important benchmarking data:

Current implied enterprise value relative to public market comparables
Revenue multiple trajectory as you approach IPO
Common stock discount narrowing as IPO probability increases
Benchmarking against recent tech IPO pricing and first-day performance

This pre-IPO analysis also helps your bankers calibrate the IPO price range and assists the S-1 financial statement preparation.

409(p) ESOP Testing

For companies with Employee Stock Ownership Plans (ESOPs), Section 409(p) requires annual testing to ensure that disqualified persons do not hold a disproportionate share of ESOP synthetic equity. Your 409A appraiser can assist with this testing as part of the overall engagement.
