A 409A valuation is generally valid for up to 12 months, assuming no material changes occur that could impact company value. Material events include fundraising rounds, acquisitions, significant revenue changes, or major market shifts. If such an event occurs, the valuation must be updated immediately. Most companies refresh their 409A annually and after each financing round. Using an outdated valuation can invalidate safe harbor protection and expose the company and equity holders to significant tax penalties?
