Difference Between Bonus Shares and Stock Split

Both bonus shares and stock splits increase the number of shares a company’s shareholders hold, but they do so for different reasons and with distinct outcomes. While bonus shares reward existing investors by converting reserves into additional equity, stock splits make shares more affordable by dividing existing shares into smaller units.

Understanding the difference between bonus shares and stock splits is essential for investors to assess how each impacts share value, ownership, and market perception. This blog breaks down their key differences, benefits, and what they mean for your investment decisions.

• Bonus Shares: Issued from reserves to reward shareholders, increasing share quantity without changing total investment value.
• Stock Split: Divides existing shares to lower the share price, making them more accessible to retail investors.
• Timing Matters: The right timing for each action depends on your business goals (e.g., liquidity, IPO).
• Liquidity & Market Impact: Both actions can improve market participation and trading volume, but do not affect the overall company value.
• No Wealth Creation: These actions restructure wealth, not create new value for shareholders.
• Communication is Key: Proper communication with investors, employees, and lenders is critical for avoiding confusion.

When a company issues bonus shares, it's essentially converting its accumulated reserves into share capital, handing out additional shares to existing shareholders at no extra cost. 

The face value of your shares stays the same. If it was ₹10 before, it stays ₹10 after. What changes is the number of shares in circulation and, as a result, the market price per share. The total value of your investment doesn't shift, just the price and quantity of the shares you own.

Why Companies Issue Bonus Shares

Bonus issues offer MSME founders more than just a way to reward shareholders. Here's why they’re a strategic choice:

1. Rewarding Shareholders Without Cash Outflow: Unlike dividends, which require cash, bonus shares capitalize on reserves. For capital-intensive businesses like manufacturing and infrastructure, this preserves working capital while keeping shareholders engaged.
2. Improving Liquidity: High share prices (₹1,200 per share) can restrict retail investor participation. A 1:2 bonus issue lowers the price to ₹400, increasing market participation, enhancing trading volume, and aiding price discovery.
3. Making Shares More Affordable: You're not discounting shares or raising cash. Instead, you're repackaging existing value into smaller units, which can boost retail sentiment by making shares feel more accessible.
4. Optimizing Reserves: If your reserves are accumulating with no immediate use, a bonus issue can strategically move surplus into share capital. This can improve your debt-to-equity ratio, which lenders take note of during credit evaluations.
5. Signaling Financial Strength: Announcing a bonus issue sends a strong message: "We have so much in reserves that we can afford to capitalize it." This is powerful signaling, especially for MSMEs preparing for mainboard listings or new funding rounds.

At S45, we’ve seen manufacturing MSMEs use bonus issues to accomplish multiple goals—rewarding early investors, improving liquidity before an IPO, and signaling financial maturity, all while preserving cash. The key is timing and having enough reserves.

A stock split increases the number of shares by proportionally reducing the face value. Unlike bonus issues, there’s no transfer of reserves to share capital; it's simply a mathematical redivision of existing equity. 

For example, Bajaj Finserv executed a 5:1 split in 2022 when the price crossed ₹15,000. As a result, retail participation surged, trading volumes increased by 340%, and shares became more accessible.

When and Why Companies Split Stocks

Stock splits aren’t just about the numbers; they serve a strategic purpose for MSMEs:

• Breaking Down Barriers to Entry: High share prices can limit retail investor participation. A ₹1,000 share price locks out smaller investors. By splitting stocks, companies make shares more accessible, boosting retail interest.
• Increasing Liquidity: Stock exchanges track average daily trading volume, which impacts index inclusion and mainboard migration. By lowering the share price, splits can encourage more trading, improving these metrics.
• Boosting Market Depth and Trading Volume: High-priced stocks often have wider bid-ask spreads, which reduces trading activity. A stock split can make shares more attractive, leading to better liquidity and more active markets.
• Psychological Impact: Even when the value is the same, lower share prices feel "more affordable," driving investor interest and trading activity. This can lead to higher demand in IPOs and more dynamic secondary market trading.

For MSMEs, the question isn’t "Should we split?" but "Does it align with our capital strategy?" If retail accessibility is a priority, especially with plans for an IPO, the answer is often yes. If you prefer an institutional-only shareholder base, a split may not be necessary.

At S45, we help founders think about capital decisions as strategic moves that shape the future of their businesses.

Now that we understand each action independently, let's compare them across the dimensions that actually matter to business owners:

Bonus shares and stock splits are both corporate actions that involve increasing the number of outstanding shares. However, they serve different purposes and impact shareholders differently. Here are the key differences between the two:

What Stays the Same

Whether you opt for a bonus issue or a stock split, four key elements remain unchanged:

1. Total Investment Value: If you held ₹10,00,000 worth of shares before, you still hold ₹10,00,000 afterward. While the number of shares and the price per share change, your total value stays the same. You're not richer or poorer.
2. Ownership Percentage: Your ownership stake remains the same. If you owned 15% before, you own 15% after. There's no dilution, unlike in rights issues where stakes can shift.
3. Market Capitalization: The total value of the company remains constant. If the pre-corporate action market cap was ₹500 crores, it stays ₹500 crores afterward, just spread across more shares.
4. Shareholding Pattern: Proportions of ownership don't change. If promoters held 60%, institutions 25%, and retail 15% before, those exact percentages stay the same after the action.

The Takeaway for Founders: These actions don’t create wealth; they restructure existing wealth. If your business fundamentals are strong, these tools can optimize your capital structure for strategic reasons like fundraising, liquidity, or succession. If not, no corporate action will fix that.

Impact on Financial Ratios

Both bonus issues and stock splits can impact financial metrics. Here’s how:

1. Earnings Per Share (EPS): EPS decreases because the same profit is spread across more shares. For a 1:1 bonus, EPS halves; for a 1:5 split, it becomes one-fifth. However, analysts focus on absolute profit growth, not EPS post-corporate action.
2. Price-to-Earnings (P/E) Ratio: The P/E ratio stays the same in an efficient market because both share price and EPS adjust. Yet, retail investors might perceive "affordability," leading to temporary P/E expansion post-split.
3. Book Value Per Share: In bonus issues, book value per share decreases since there are more shares with the same net worth. Stock splits don’t affect this since the balance sheet stays unchanged. Investors focus on total net worth, not per-share book value.
4. Return on Equity (ROE): In bonus issues, the increase in share capital can make ROE appear to drop. However, this is an optical effect, and stock splits don’t affect ROE as equity remains the same.

The Practical Implication: Expect changes in your financial ratios following corporate actions. Advance communication with analysts, investors, and lenders is crucial to ensure they adjust their models and don’t misinterpret these changes as performance issues.

At S45, we guide founders through these ratio impacts before taking any action, because while the technical side is straightforward, strategic communication is where most founders need help.

You understand what bonus shares and stock splits are, now, let's discuss when they make strategic sense for your business stage and objectives.

When it comes to scaling your MSME, strategic decisions around capital structure can make all the difference. Let’s break down the key principles founders need to consider to make these decisions work in their favor:

• Strategic Tools, Not Perks: Bonus issues and stock splits are decisions that shape your long-term capital structure. They’re not just for market hype or keeping up with competitors; they play a key role in fundraising, succession planning, and liquidity.
• Timing is Everything: When you execute these actions matters more than the actions themselves. A bonus issue 18 months before an IPO is brilliant; six months before can lead to chaos. A stock split during stable times enhances liquidity; during fundraising talks, it can cause confusion.
• Regulatory Compliance is Essential: Follow the Companies Act 2013 to the letter; board approvals, shareholder consents, and timely filings are a must. Skipping these steps risks fines, penalties, and damage to your reputation. Budget ₹3-7 lakhs and allow 3-4 months for proper execution.
• Clear Communication Matters: Whether it’s institutional investors, lenders, or employees with ESOPs, each group needs tailored communication. Announcements without context can cause unnecessary volatility. Transparency builds trust.
• Think Long-Term: Align your decisions with your 5-year plan. If an IPO is on the horizon, the timing of a stock split or bonus issue matters. Build a coherent strategy that integrates these actions with your broader business goals.

By considering the timing, staying compliant with regulations, and ensuring clear communication, you can harness the power of these tools to benefit your business in the long run.
