Meaning
Contractual provisions protect investors against the dilution of equity stakes when a company issues new shares at a valuation lower than the original investment. This conversion price adjustment functions as a rebalancing mechanism that lowers the price at which preferred shares convert into common stock. The protection triggers if subsequent financing rounds occur at a lower share price than the initial issuance.
Dilution Protection
Preferred shareholders retain their target ownership percentage by increasing the quantity of common shares received upon conversion. A formula dictates the extent of the shift by comparing the pre-money valuation of the new round against the price paid during the primary investment. Anti-dilution math preserves the economic parity of early capital.
Triggering Mechanism
Weighted average arrangements calculate a new price based on both the number of new shares issued and the reduction in price per share. Full ratchet clauses provide a more aggressive outcome by adjusting the conversion price to the exact level of the new issuance regardless of the volume of new equity. Issuers typically prefer the former to moderate the impact on existing cap tables while investors seek the latter to ensure absolute protection against downward valuation cycles.
Capital Impact
Management teams manage the dilution effects of these provisions when negotiating term sheets during equity fundraising events. A high volume of issued shares at a reduced price creates a significant overhang on the common equity pool held by founders and employees. Final capitalization tables depend on the interaction between these adjustment clauses and the overall valuation achieved in follow-on financing.
