Meaning
An anti-dilution provision adjusts the conversion price of preferred shares if subsequent equity is issued at a lower valuation. For early investors, a preferred stock ratchet shields their investment from the devaluing effects of a down round. This feature remains active through successive rounds until a qualifying public offering occurs.
It ceases to apply once those shares are converted to common stock.
Adjustment Trigger
The reset occurs automatically upon the execution of a financing agreement at a price below the existing conversion threshold. In a full ratchet scenario, the old conversion price drops to match the new lower price. This single event changes the cap table.
It forces a redistribution of ownership percentages.
Share Dilution
The resulting adjustment causes common stockholders, including founders, to experience severe dilution of their ownership. Because the preferred conversion price decreases, each preferred share converts into more common shares. This outcome alters the voting balance of the company.
It can restrict the founders’ ability to manage the business.
Protecting Clause
A well-negotiated agreement can include carve-outs to limit the impact of the ratchet. These exceptions include equity issued for option pools and equipment leases. Restricting the trigger to major rounds reduces the risk of extreme founder dilution.
