Investors often consider the impact of a company issuing more stock shares, particularly on the cost of equity. The cost of equity represents the return that investors expect for holding a company's stock. When a company issues additional shares, it can influence the stock price, investor perception and even the company's overall financial structure.
A financial advisor can help you evaluate how a company's decision to issue more stock shares can impact its potential as an investment.
Does Issuing Shares Decrease the Cost of Equity?
Issuing more stock shares does not directly decrease the cost of equity. The cost of equity is influenced by how investors perceive the risk. If the newly raised capital from issuing more shares is used for growth opportunities or to reduce debt, investors may perceive this positively, which could stabilize or even slightly reduce the cost of equity.
However, in many cases, the increased share count leads to dilution of existing shares, potentially impacting the stock price negatively. As a result, investors might demand higher returns to compensate for what they see as increased risk, ultimately raising the cost of equity.
How Does Issuing Shares Affect the Cost of Equity?
Dilution of Existing Shares
When a company issues more shares the total number of outstanding shares increases, which means that each share now represents a smaller ownership stake in the company. This dilution of existing shares potentially reduces the earnings per share (EPS) and lowering the value of their holdings, as each share now has a smaller claim on the company's profits.
For example, if a company has one million shares outstanding and earns $1 million in profits, the EPS is $1 per share. If the company issues an additional 500,000 shares, bringing the total to 1.5 million shares, the EPS drops to around $0.67 per share.
Existing shareholders may view dilution negatively, especially if the issuance does not lead to improved earnings or future growth. The perception of decreased value can contribute to a lower stock price, which, in turn, may affect the cost of equity by increasing the expected return for investors.
Impact on Investor Perception
If a company issues shares to finance growth projects or acquisitions that could increase future profits, investors might interpret this positively. They may view the issuance as a strategic move that enhances the company's investment return and growth, possibly reducing perceived risk.
However, investors may view this negatively if they believe that the additional shares are being issued because the company is struggling to generate sufficient internal cash flow. Such a perception can increase the cost of equity because investors may require a higher return to compensate for what they perceive as greater risk.
Changing Capital Structure
Increasing equity through share issuance changes a company's capital structure, particularly by altering the ratio of debt to equity. A company's capital structure consists of debt, equity or a combination of both.
By issuing more shares, a company increases its equity, which can reduce reliance on debt. A lower debt-to-equity ratio is often seen as a reduction in financial risk, as the company has less obligation to make interest payments. This shift can appeal to investors looking for stable returns, as companies with higher equity ratios are generally considered to be financially sound and less vulnerable during economic downturns.
But a capital structure with too much equity relative to debt might reduce the tax benefits associated with interest payments on debt. While a balanced capital structure can lower financial risk and potentially reduce the cost of equity, an overly equity-heavy structure may not be optimal for maximizing shareholder returns.
Supply and Demand Dynamics
When new shares are introduced to the market, the increased supply may lead to a temporary drop in the stock price if demand does not keep pace. This price decrease can influence the cost of equity, as investors may now require a higher return to justify the perceived additional risk.
But if there is strong investor interest and demand for the newly issued shares, it may counterbalance the increased supply, stabilizing the stock price. This is especially likely when a company is issuing shares as part of a growth initiative and investor sentiment and increased demand help support the share price, which may have a neutral or even positive effect on the cost of equity.
Bottom Line

Issuing more stock shares does not necessarily decrease the cost of equity. The impact depends on investor perception, the use of raised capital, changes to the capital structure and the response of the stock market. While issuing shares can provide valuable capital for growth, it also carries the risk of share dilution and may affect investor sentiment.
