The Complete 409A Valuation Lifecycle

Managing 409A valuations across your startup's growth is an ongoing responsibility. This guide walks through every stage of the process — from your first option grant to pre-IPO readiness.

Before Your First Option Grant

The moment you decide to build an equity incentive plan (EIP) and issue stock options to employees, advisors, or consultants, you need a 409A valuation. The timeline is important: the 409A must be completed before the first option grant — you cannot retroactively apply a valuation to past grants.

For most early-stage companies, this means ordering your 409A when you start building your team and plan to use options as compensation. Pre-Seed valuations are typically straightforward and can be completed in 5–7 business days.

Choosing the Right Methodology

The correct valuation approach depends on your stage and financial profile:

  • Pre-revenue / Pre-Seed: Asset approach (net asset value) plus market comparables based on comparable transactions and stage-appropriate risk adjustments
  • Early revenue / Seed: Market approach using ARR or Revenue multiples from comparable public SaaS/tech companies, supplemented by DCF
  • Post-Seed through Series A: Option Pricing Model (OPM) to allocate enterprise value across share classes; DCF for companies with meaningful revenue
  • Series B and beyond: Probability-Weighted Expected Return Method (PWERM) modelling multiple exit scenarios, combined with OPM for current period allocation
  • Growth / Pre-IPO: Full enterprise valuation using market comparables, DCF, and pre-IPO benchmarking; may include IPO as one of the PWERM scenarios

What to Provide Your Appraiser

The quality of your 409A report depends on the quality of information you provide. Prepare:

  • Most recent financial statements (P&L, balance sheet, cash flow)
  • Monthly revenue and ARR data for the trailing 12 months
  • Financial projections for 3–5 years (even rough ones help)
  • Cap table (fully diluted share count, all classes, all option pools)
  • Details of your most recent preferred round (price, liquidation preference, participation rights)
  • Company overview / pitch deck (business model, market size, competitive positioning)
  • List of key customers, contracts, or LOIs (for revenue-stage companies)

Reading Your 409A Report

A complete 409A report should contain:

  1. Executive summary: The conclusion of FMV of common stock per share as of the valuation date
  2. Company overview: Business description, financial summary, industry context
  3. Methodology section: Which approaches were used and why; weighting applied to each
  4. Market comparables: The public companies or transactions used as benchmarks
  5. Equity allocation: How enterprise value was allocated between preferred and common using OPM/PWERM
  6. DLOM analysis: The discount applied for lack of marketability and the basis for it
  7. Conclusion of value: The final FMV of common stock per share
  8. Appraiser certification: Signed statement of the appraiser's independence and qualifications

409A Management Calendar

To stay compliant without disruption to your hiring plans, follow this calendar approach:

  • Annual: Order a refresh valuation at least 30 days before the 12-month expiry of your current one
  • Post-funding: Order a new 409A within 2–4 weeks of closing any priced round
  • Pre-hiring push: If you plan to issue a large batch of options, order a 409A 2–3 weeks in advance
  • Material events: If revenue doubles, a major customer is lost, or you receive an acquisition offer, consult your appraiser about whether a re-valuation is warranted
