Meaning
Equity dilution risk describes the structural weight of unallocated option pools and promised future grants resting upon a company before operational milestones justify the reduction. Cap table overhang measures the proportion of authorized shares promised to advisors or future hires against the total equity currently issued. This condition forces founders into defensive postures during subsequent financing rounds because incoming investors demand clean ownership ledgers before deploying capital.
The boundary of this mechanism stops at the legal issuance of shares, since unexercised options remain promises rather than active holdings until vested and exercised.
Option Pool Inflation
Early equity allocations often reserve twenty percent of total shares for prospective personnel before the enterprise generates revenue. Founders establish these reserves to attract engineering talent without immediate cash compensation. Unallocated percentages sit dormant on ledgers while diminishing the relative stake of existing shareholders.
New funding rounds frequently require expanding this reserve pool before investors purchase preferred stock, which accelerates founder dilution beyond initial projections.
Valuation Discount
Investors discount enterprise value proportionally to the outstanding reserve overhang remaining unallocated on ledgers. Markets price companies by dividing total valuation by fully diluted shares rather than issued shares alone. This mathematical adjustment reduces the effective price per share received during primary transactions.
Founders absorb this valuation penalty through lower net proceeds on preferred share sales because incoming capital shares the future upside with phantom equity.
Restructuring Cost
Reclaiming overhang requires renegotiating pool sizes with existing investors during term sheet negotiations. Legal hours and administrative overhead accumulate when counsel drafts amendments to option plans and adjusts vesting schedules. Founders spend considerable attention balancing employee recruitment incentives against the immediate cost of equity expansion.
Dilution disputes consume operating hours that otherwise support revenue generation and product delivery.
