The pecking order theory, in finance, describes how companies prioritize their sources of financing. It suggests that companies prefer internal financing (retained earnings) first, then debt, and finally equity. This preference stems from information asymmetry and the signaling effect that different financing choices can have on investors.
The core idea is that managers know more about their company’s prospects and risks than outside investors do. This information asymmetry can lead to problems when a company needs to raise external capital. If managers believe the company’s stock is undervalued (and they know it!), they will be reluctant to issue new shares because doing so would essentially sell the company short. Conversely, if managers believe the company’s stock is overvalued, they might be tempted to issue new shares, benefiting the existing shareholders at the expense of new ones.
This potential conflict of interest makes investors wary of equity offerings. They interpret a company’s decision to issue new stock as a signal that the company’s prospects might not be as good as previously believed, leading to a decline in the stock price. This is because investors assume management only issues equity when they believe the price is relatively high and therefore, diluting existing shares is less detrimental.
To avoid this negative signaling effect and associated costs, companies prefer to use internal funds (retained earnings) whenever possible. Retained earnings don’t require the company to interact with external capital markets and therefore avoid conveying any potentially negative information. When internal funds are insufficient, companies will then turn to debt financing. While debt also involves interaction with external investors, it is generally considered less risky than equity from a signaling perspective. Issuing debt suggests that the company is confident in its ability to generate sufficient cash flow to repay the loan, which is seen as a positive signal.
Furthermore, the cost of debt is often lower than the cost of equity due to the tax deductibility of interest payments. Debt also doesn’t dilute existing ownership, making it a more attractive option for managers who are concerned about maintaining control of the company. Only as a last resort, when internal funds and debt are insufficient, will companies resort to issuing new equity.
The pecking order theory suggests that a company’s capital structure is a result of its financing decisions, not a deliberate attempt to achieve an optimal mix of debt and equity. Unlike other capital structure theories that focus on finding the balance that minimizes the cost of capital, the pecking order theory emphasizes the importance of information asymmetry and the costs associated with external financing. Therefore, companies don’t necessarily strive for a specific debt-to-equity ratio; instead, their capital structure evolves based on their financing needs and the available options, following the pecking order: internal funds, then debt, and finally equity.
