Pecking-Order Theory: Why Companies Hate Issuing Equity

The defaults above (V0=$800M, NPV=$20M, issuance=$100M, alpha=0.75) recreate the canonical Myers + Majluf worked example. New equity buys 100/(0.75800 + 100) = 100/700 = 14.286% of the post-issuance firm. Post-project value is 800 + 100 + 20 = $920M. Existing shareholders end up with 85.714% 920 = $788.57M — a $11.43M LOSS even though the project NPV is +$20M. The CFO rationally rejects a positive-NPV project because the equity-issuance discount transfers more value to new shareholders than the project creates. Now drag alpha to 1.00 (no asymmetry): the same project ACCEPTS, with existing shareholders gaining ~$17.78M. The friction the formula isolates is the entire reason CFOs prefer internal cash.

Pecking-order is the ONLY major capital-structure theory that predicts the empirically-observed NEGATIVE correlation between profitability and leverage. Profitable firms generate retained earnings, so they fund investment internally and never need to issue debt — their leverage stays low. Unprofitable firms run out of internal finance, must issue debt or equity, and end up with higher leverage. Tradeoff theory predicts the OPPOSITE (profitable firms have more taxable income to shield and lower distress risk, so they should carry MORE debt). The leverage-profitability fact is the single sharpest empirical test that distinguishes the two theories — and pecking-order wins.

Going Deeper — three frictions that make pecking-order ALSO break down. The hierarchy is a strong empirical regularity, but three real-world frictions complicate the clean ordering. (1) Growth firms with no internal finance: a pre-revenue biotech or SaaS firm cannot 'use internal cash first' — there is no cash. The hierarchy collapses to 'equity (the only option) > nothing,' and the equity discount is borne whether managers like it or not. (2) Signaling-cost-reducing devices: rights issues (pro-rata to existing shareholders, no adverse-selection cost because existing holders price the issue) and PIPE deals (private placements with strategic investors who do their own diligence) can lower the equity discount enough to make equity-first rational in specific situations. (3) Behavioral / managerial-preference frictions: some CFOs systematically over-prefer debt for empire-protection reasons (avoiding scrutiny from new equity holders), pushing leverage above what pecking-order alone would predict. Reading a real CFO's financing choice means asking which of these frictions dominates for THIS firm — not just applying the hierarchy mechanically. AI prompt: 'For this ticker, walk through the pecking-order hierarchy. Where does internal finance run out? What does the debt capacity look like? Would equity be a forced-equity (no alternative) or choice-equity (overvaluation signal) issuance?'
