Seasoned Equity Offering

An established issuer normally registers a block of securities in advance under a shelf arrangement, then draws on that registration when conditions suit. Three distribution routes dominate. A fully marketed offering involves an underwriting syndicate, investor roadshow and a fixed price struck at a discount to the prevailing quote; the bank either firm-commits (buying the block and bearing resale risk) or acts on a best-efforts basis. An accelerated bookbuild compresses the same process into hours, usually overnight, trading a wider discount for speed and certainty. An at-the-market programme instead dribbles shares into the open market through a broker over weeks or months, at prevailing prices, avoiding an announcement discount but giving the issuer no guarantee of the total raised.

Because the security already has a public price and a trading history, information asymmetry is lower than at flotation, so underwriting spreads on seasoned issues are materially thinner than on initial public offerings.

Dilution operates on two axes. Ownership dilution is mechanical: a holder who does not subscribe sees their percentage claim fall in proportion to the increase in shares outstanding. Economic dilution depends on price: if new shares are sold below the pre-issue price, wealth transfers from existing holders to new subscribers; if sold at or above intrinsic value, incumbents can be left better off.

Many jurisdictions grant pre-emption rights, so the issue takes the form of a rights offering in which existing holders receive subscription entitlements pro rata. The theoretical ex-rights price is the total value of the enlarged equity divided by the enlarged share count: old shares multiplied by the cum-rights price, plus new shares multiplied by the subscription price, all divided by the sum of old and new shares. The value of one right equals the cum-rights price minus that theoretical ex-rights price, scaled by the number of rights needed per new share. A holder who sells the rights rather than subscribing is, in theory, left whole.

Proceeds appear as a cash inflow within financing activities, alongside an increase in cash and cash equivalents. On the balance sheet, par value lifts common stock and the remainder credits additional paid-in capital or share premium; issuance costs are typically charged against that premium rather than run through profit or loss. Total equity rises by the net proceeds, so leverage ratios such as debt to equity and debt to capital fall immediately even though no debt was repaid.

Earnings per share is computed on a weighted average share count, so an issue late in a fiscal year dilutes reported EPS far less than the same issue in January, and the full effect only appears in the following period. Book value per share moves toward the issue price: it rises when shares are sold above book and falls when sold below. Return on equity typically declines on impact because the capital base expands before the funded projects generate earnings.

Pecking order reasoning holds that managers prefer internal funds, then debt, and treat external equity as the last resort, precisely because informed insiders will rationally issue stock when they judge it richly priced. Rational investors anticipate this, which is why announcement returns for marketed seasoned offerings are, on average, negative in developed markets. The inference is weaker where the raise is pre-committed, regulator-mandated for capital adequacy, or structured as a rights issue at a deep discount to all holders equally.

At Level I you should be able to separate a primary issue that funds the company from a secondary sale in which an existing blockholder cashes out, restate share count and equity after an issue, compute a theoretical ex-rights price and the value of a right, and explain the direction of movement in EPS, book value per share and leverage ratios that follows.
