    409A Valuation

    In one line
    An independent fair-market-value appraisal of common stock used to set tax-compliant strike prices for employee stock options.
    Definition
    A 409A valuation is an independent appraisal of a private company's common stock fair market value, performed under the safe harbor of IRC Section 409A (added by the American Jobs Creation Act of 2004). The valuation determines the strike price at which employee stock options can be granted without triggering punitive 409A tax penalties on the employee. 409A valuations are typically refreshed annually, after each priced financing round, or following any material corporate event.
    Why it matters
    MedTech 409A valuations typically reflect a material discount to preferred stock price because of the preferred's liquidation preference and protective provisions; this discount narrows as the company approaches an IPO.
    Common pitfalls
    • Letting a 409A valuation lapse and granting options at a stale price — exposes employees to personal tax penalties.
    • Granting options between a financing close and the refreshed 409A.

    Why compare MedTech terms side by side?

    MedTech terminology is full of pairs that look interchangeable but carry very different regulatory, clinical, and commercial consequences. Picking the wrong framework, pathway, or standard early in a project can add months to a submission, invalidate clinical evidence, or trigger an audit finding. Side-by-side comparison is the fastest way to surface those differences before they become costly mistakes.

    Each comparison on this page pulls from the same vendor-neutral, sourced definitions used throughout the MedTech Terms glossary. You see the one-line summary, the formal definition, why it matters in practice, common pitfalls, and the primary sources (FDA guidance, EU MDR/IVDR articles, ISO/IEC standards, MDCG documents, IMDRF principles) that back each entry. That makes the comparison defensible in regulatory strategy memos, design reviews, and submission narratives.
