Meaning
Anti-dilution mechanisms that continuously recalculate conversion ratios based on subsequent financing rounds form specialized protective clauses. In investor agreements, dynamic ratchet provisions adjust the share price of preferred stock downward whenever new equity is issued at a price lower than earlier rounds. The clause governs conversion ratios between preferred and common shares to preserve the investor’s relative ownership value.
It stops applying once an initial public offering occurs or when preferred stock converts into common equity.
Adjustment Trigger
Downward shifts in corporate valuation initiate structural equity adjustments across existing stock classes. Implementing dynamic ratchet provisions increases the volume of common shares issued upon preferred stock conversion, directly offsetting valuation decline for early investors. Founders bear the resulting dilution because common equity pool shares shrink to accommodate the investor’s expanded share allocation.
Ownership Reallocation
Capital restructurings under down-round conditions redistribute corporate voting power away from common shareholders. Preferred investors expand their share count automatically without contributing secondary cash reserves. Founders who lose equity percentage under ratchet adjustments experience diminished voting authority and reduced exit payouts.
Equity distribution realigns toward capital providers during distress.
Valuation Floor
Contractual limits often restrict full-ratchet adjustments to weighted-average formulas. These formulas balance dilution across all investor classes rather than penalizing common shareholders exclusively.
