How Public Companies Raise Money: Equity, Debt, and More


For public companies, raising capital is essential for funding growth, acquisitions, research, and operations. Whether it’s Tesla raising billions for expansion, Apple issuing bonds to buy back stock, or startup IPOs flooding Wall Street, the way companies secure funding can have a huge impact on their stock price, financial health, and investor returns.

But how exactly do public companies raise money? Let’s break down the primary methodsβ€”equity financing, debt financing, and hybrid approachesβ€”along with the pros, cons, and real-world examples.


1. Equity Financing (Selling Shares)

πŸ“Œ Definition: A company issues new shares of stock to investors in exchange for capital.

πŸ”Ή Common Types of Equity Financing

βœ” Initial Public Offering (IPO) – A company goes public by selling shares for the first time (e.g., Facebook IPO in 2012).
βœ” Secondary Offerings – Public companies issue additional stock after their IPO to raise more money.
βœ” At-the-Market (ATM) Offerings – A company gradually sells new shares over time instead of a single large offering.
βœ” Private Placements – Selling shares directly to institutional investors instead of the public.

βœ… Pros of Equity Financing

βœ” No Debt Obligation – The company doesn’t owe money or need to make interest payments.
βœ” Can Fund High-Risk Growth – Ideal for startups or companies in aggressive expansion phases.
βœ” Stronger Balance Sheet – Less debt means a healthier financial position.

❌ Cons of Equity Financing

β›” Dilutes Existing Shareholders – Issuing more shares reduces ownership percentages and can lower EPS (earnings per share).
β›” Stock Price Pressure – If investors perceive dilution as negative, the stock price may drop.
β›” Loss of Control – If too many shares are issued, large investors may influence company decisions.

πŸ“Œ Famous Examples

  • Facebook’s IPO (2012): Raised $16 billion, one of the largest IPOs in history.
  • Tesla’s Secondary Offerings: Frequently raised capital by selling shares to fuel expansion, including a $5 billion stock offering in 2020.

2. Debt Financing (Issuing Bonds & Loans)

πŸ“Œ Definition: A company borrows money from investors or banks and agrees to pay it back with interest.

πŸ”Ή Common Types of Debt Financing

βœ” Corporate Bonds – Companies issue bonds to investors, paying interest over time (e.g., Apple issuing bonds for stock buybacks).
βœ” Bank Loans & Credit Lines – Borrowing directly from banks or financial institutions.
βœ” Convertible Debt – Bonds or loans that can be converted into stock if certain conditions are met.
βœ” Commercial Paper – Short-term unsecured loans used for quick cash flow needs.

βœ… Pros of Debt Financing

βœ” No Ownership Dilution – Unlike equity, debt does not reduce shareholder ownership.
βœ” Tax Benefits – Interest payments are tax-deductible, reducing taxable income.
βœ” Leverage Potential – If capital is used effectively, returns can exceed borrowing costs.

❌ Cons of Debt Financing

β›” Debt Repayment Obligations – Unlike equity, debt must be repaid, adding financial risk.
β›” Interest Payments Reduce Profits – High debt burdens can eat into company earnings.
β›” Credit Rating Risk – Too much debt can lead to credit downgrades, making future borrowing more expensive.

πŸ“Œ Famous Examples

  • Apple’s Bond Issuance (2020): Issued $8.5 billion in bonds at ultra-low interest rates to fund stock buybacks.
  • Boeing’s Debt Crisis (2020): Raised $25 billion through bonds to survive the COVID-19 downturn but now faces massive debt obligations.

3. Hybrid Financing (Mix of Equity & Debt)

πŸ“Œ Definition: A company raises money using a combination of debt and equity instruments to balance financial risk.

πŸ”Ή Common Types of Hybrid Financing

βœ” Convertible Bonds – Bonds that convert into shares if stock prices hit a certain level.
βœ” Preferred Stock – Stock with fixed dividends that behaves like a bond but without voting rights.
βœ” Warrants & Options – Companies offer investors the right to buy shares at a fixed price in the future.

βœ… Pros of Hybrid Financing

βœ” Lower Cost of Capital – Convertible bonds often have lower interest rates than traditional bonds.
βœ” Flexibility for Investors – Appeals to both income-seeking and growth-focused investors.
βœ” Avoids Immediate Dilution – If structured properly, dilution happens only if stock prices rise significantly.

❌ Cons of Hybrid Financing

β›” Complexity – Investors may struggle to value these securities properly.
β›” Dilution Risk (If Converted to Equity) – Convertible bonds eventually increase share count if exercised.

πŸ“Œ Famous Examples

  • Tesla’s Convertible Bonds (2014-2019): Raised billions in convertible debt that later converted into stock as shares soared.
  • Berkshire Hathaway’s Preferred Stock Deals: Warren Buffett’s firm invested in companies like Goldman Sachs (2008) & Occidental Petroleum (2019) using preferred shares with guaranteed high dividends.

4. Government & Alternative Financing

πŸ“Œ Definition: Companies can also raise money through grants, subsidies, joint ventures, and partnerships.

πŸ”Ή Examples

βœ” Government Grants & Subsidies – Companies in clean energy, biotech, or infrastructure may receive federal funding (e.g., EV tax credits for Tesla & Rivian).
βœ” Strategic Partnerships – Joint ventures with large corporations (e.g., Google investing in AI startups).
βœ” SPACs (Special Purpose Acquisition Companies) – Companies go public by merging with a pre-funded shell company instead of an IPO.

πŸ“Œ Famous Examples

  • SpaceX & NASA Contracts: Elon Musk’s company raised billions through government space contracts.
  • Rivian’s Amazon Deal: Amazon pre-ordered 100,000 Rivian EVs, helping fund the company before its IPO.

Final Thoughts: Which Method Is Best?

βœ” Startups & High-Growth Companies β†’ Favor Equity (IPOs, stock offerings)
βœ” Stable, Profitable Companies β†’ Favor Debt (bonds, loans)
βœ” Tech & Disruptors β†’ Often Use Hybrid Methods (convertible bonds, partnerships)

πŸ”Ή Tesla leveraged equity (stock sales) to fund rapid growth.
πŸ”Ή Apple strategically used debt (bonds) to repurchase shares and boost EPS.
πŸ”Ή Amazon uses partnerships (Rivian deal) to fund its future without issuing new stock.

For investors, understanding how a company raises capital can provide insight into its growth strategy, risk tolerance, and financial health.
