Meaning
Financial metrics governing equity financings establish individual share value by dividing the aggregate enterprise valuation immediately following new capital investment by the fully diluted share count. The post money share price determines the exact ownership percentage acquired by incoming investors and measures the formal price per share for preferred equity issuances. Its application governs the conversion terms of unpriced convertible notes and simple agreements for future equity, terminating its operative pricing function once the financing round closes and the corporate charter amendment takes effect.
Mathematical Derivation
Equity valuation arithmetic establishes the per-share figure through precise formulas agreed upon in the venture term sheet. The post-money valuation represents the sum of the negotiated pre-money valuation and the aggregate gross cash investment. Dividing this aggregate figure by the fully diluted shares, including all outstanding common stock, preferred shares, and unallocated option pool expansions, yields the post money share price.
Expanding the employee option pool prior to closing compresses the pre-money share value while keeping the post-money share valuation steady for incoming preferred investors.
Conversion Mechanics
Convertible securities, including notes and simple agreements for future equity, convert into shares based on calculations directly pegged to round valuation metrics. When these convertible instruments feature post-money valuation caps, the post money share price acts as the benchmark to determine conversion ratios and identify investor dilution boundaries. A lower share price increases the aggregate number of shares issued to debt and convertible holders, substantially reducing existing common founder ownership.
Mathematical precision in defining what securities are included in the fully diluted denominator prevents post-closing ownership allocation disputes.
Contractual Authority
Definitive transaction documents, primarily the certificate of incorporation and the preferred stock purchase agreement, record the official share price applicable to the financing series. This figure establishes the benchmark for liquidation preference payouts, calculating the exact capital returned to preferred holders prior to any junior common distributions. Dividend rights, anti-dilution conversion ratios, and redemption values are calculated directly as multiples of this stated baseline.
The certified post money share price remains fixed in corporate governance documents until subsequent equity financings, stock splits, or recapitalizations formally amend the charter.
