An equity issue is the sale of newly created shares of stock by a company to raise capital. The transaction increases the total number of shares outstanding and brings in cash that, unlike debt, never has to be repaid. Companies use the proceeds to fund growth, pay down loans, finance acquisitions, or shore up the balance sheet. How a given equity issue works depends on whether the company is already public, who it wants to sell to, and which parts of federal securities law apply.
Types of Equity Offerings
The structure a company chooses determines who can buy the shares, how much disclosure is required, and how long the process takes.
Initial Public Offering
An initial public offering, or IPO, is the first time a private company sells stock to the general public. The company files a registration statement with the Securities and Exchange Commission, and once the SEC declares it effective, shares begin trading on a stock exchange.1U.S. Securities and Exchange Commission. Going Public The IPO converts the company from private to public, giving founders and early investors a path to eventually sell their stakes while bringing in substantial new capital.
Follow-On Public Offering
A follow-on public offering is a sale of additional shares by a company that already trades publicly. In a primary follow-on, the company creates brand-new shares and keeps the proceeds. In a secondary follow-on, existing large shareholders sell some of their own holdings, and the cash goes to them rather than the company. Both use the public markets, but only the primary version raises capital for the business itself.
Private Placement
A private placement sells securities directly to a limited group of investors without a full public registration. Most placements rely on exemptions under Regulation D of the Securities Act.2eCFR. 17 CFR 230.500 – Use of Regulation D Under Rule 506(b), a company can sell to an unlimited number of accredited investors plus up to 35 non-accredited investors, but it cannot advertise the offering. Rule 506(c) allows general solicitation, but every purchaser must be accredited.3U.S. Securities and Exchange Commission. Exempt Offerings
An accredited investor is an individual with a net worth above $1 million excluding the primary residence, or individual income above $200,000 in each of the two most recent years with a reasonable expectation of the same this year. Joint income with a spouse or spousal equivalent of $300,000 also qualifies.4U.S. Securities and Exchange Commission. Accredited Investors
Rights Offering
A rights offering gives existing shareholders the first chance to buy newly issued shares, usually at a discount to the market price. Each shareholder receives rights in proportion to the shares already held, so anyone who exercises in full keeps the same ownership percentage. Shareholders who don’t want to participate can sometimes sell their rights, depending on the terms of the offering.
Shelf Registration
A shelf registration lets an eligible company file one registration statement with the SEC and then sell securities off that shelf in batches over time, rather than registering each sale separately. Companies using Form S-3 for this purpose generally need a public float of at least $75 million held by non-affiliates and at least 12 months of timely SEC filings.5U.S. Securities and Exchange Commission. Form S-3 When the stock price is favorable or an acquisition appears, the company can tap the shelf and raise money in days rather than months.
How an Equity Issue Comes Together
A public offering moves through several overlapping stages under federal securities law. From board approval to the first trade, the timeline runs from a few months to over a year depending on the company’s readiness and the depth of SEC review.
Board Approval and Underwriter Selection
The board of directors formally authorizes the offering, and the company then selects one or more investment banks as underwriters. The lead underwriter structures the deal, coordinates due diligence, and typically guarantees the sale by agreeing to purchase any unsold shares. That guarantee, called a firm commitment underwriting, is why the choice of bank affects both pricing and demand.
Registration and SEC Review
Federal law prohibits selling securities to the public unless a registration statement is in effect or an exemption applies.6Office of the Law Revision Counsel. 15 USC 77e – Prohibitions Relating to Interstate Commerce and the Mails Most IPOs use Form S-1, which requires detailed disclosure of the business, audited financial statements, risk factors, the planned use of proceeds, and the terms of the offering.7U.S. Securities and Exchange Commission. Form S-1 SEC staff review the filing and issue comment letters asking for revisions or additional disclosure. No shares can be sold until the SEC declares the statement effective.8U.S. Securities and Exchange Commission. What Is a Registration Statement
Roadshow, Pricing, and Settlement
While the registration is under review, the company and its underwriters market the deal to institutional investors through a series of presentations known as the roadshow. Underwriters collect non-binding indications of interest, a process called book building, and that demand picture drives the final offering price. Once the registration is effective and the price is set, shares are allocated and trading begins. The standard settlement cycle is now T+1: the buyer pays and receives shares one business day after the trade.9U.S. Securities and Exchange Commission. Shortening the Securities Transaction Settlement Cycle At closing, the underwriters wire the net proceeds to the company — total capital raised minus underwriting fees and other issuance expenses.
What an Equity Issue Costs
Selling stock is not cheap. The biggest line item is the underwriting spread, which is the difference between what the underwriters pay the company for the shares and what they resell them to investors for. For moderate-size IPOs (roughly $20 million to $200 million in proceeds), the gross spread has been remarkably consistent at 7% of total proceeds. Billion-dollar offerings typically pay a lower spread, averaging closer to 4.5% to 5%.
On top of the spread, companies pay legal fees, accounting and audit costs, SEC filing fees, stock exchange listing fees, and printing costs for the prospectus. For a mid-size IPO, these additional expenses can run $2 million to $5 million. Follow-on offerings tend to cost less because the company already has reporting infrastructure in place, but the underwriting spread still represents most of the expense.
Effects on Existing Shareholders
Every equity issue rearranges the ownership math for shareholders already on the books. Some effects are pure arithmetic. Others shift corporate power.
Ownership Dilution
Dilution is the most immediate consequence. Hold 100,000 shares of a company with 1 million outstanding, and you own 10%. Issue 250,000 new shares, and total shares jump to 1.25 million while your stake drops to 8%, even though you still hold the same count. If the new money comes in at a fair valuation, the per-share value shouldn’t fall; your smaller slice is a slice of a bigger pie. If the shares are priced at a discount, existing holders bear real economic loss.
Voting Power
Each common share typically carries one vote on board elections and major corporate actions. New shares expand the total vote count, so every existing holder’s relative influence shrinks in proportion to the dilution. For retail investors this rarely matters. For founders or activist shareholders holding a controlling block, even a few percentage points can swing a proxy fight.
Pre-Emptive Rights
Some corporate charters give existing shareholders pre-emptive rights, the option to buy their proportional share of any new offering before outsiders can. Own 5% and the company issues 100,000 new shares, and you can purchase 5,000 to hold your stake steady. These rights are more common in smaller or closely held companies and are the mechanism behind rights offerings.
Lock-Up Agreements
In an IPO, insiders — founders, executives, early investors — typically sign lock-up agreements that bar them from selling for a set period. Most lock-ups last 180 days.10Investor.gov. Initial Public Offerings: Lockup Agreements No federal law requires them; they are a contractual arrangement between the underwriters and the company’s insiders meant to prevent a flood of selling that could depress the stock in its first months of trading. When the lock-up ends, a wave of insider sales often follows, and the price sometimes dips temporarily as supply increases.
Market Reaction
How investors read an equity issue depends heavily on why the company is raising money. An offering tied to a specific acquisition or a new production facility tends to land neutrally or positively. An offering described as shoring up the balance sheet or covering general corporate purposes tends to spook investors, because it suggests management sees trouble ahead or that operating cash flows are not covering expenses. Prices often fall a few percent on announcement day for exactly this reason: investors assume a company wouldn’t dilute them unless it had to.
How the Proceeds Are Recorded
Money raised in an equity issue is not revenue. On the balance sheet, cash goes up as an asset, and the offsetting entry goes into stockholders’ equity, split between two accounts. Common Stock is credited only for the par value of each share, often a fraction of a cent. Additional Paid-in Capital, or APIC, absorbs everything above par. A company issuing one million shares with a $0.01 par value at $25 per share increases Common Stock by $10,000 and APIC by $24,990,000.
Issuance costs — underwriting fees, legal expenses, filing fees — do not run through the income statement. They reduce APIC directly, so the balance sheet reflects only the net cash actually received.11Deloitte Accounting Research Tool. Deloitte’s Roadmap – Distinguishing Liabilities From Equity – Section: 10.2.1 Recognition
The new shares also affect earnings per share. Basic EPS equals net income divided by the weighted average number of common shares outstanding during the period.12Deloitte Accounting Research Tool. Earnings per Share – Section: Basic EPS More shares in the denominator means a lower EPS even when profits are unchanged. Analysts watch that dilution closely, and it is part of why prices sometimes slip when a new offering is announced.
Tax Treatment
An equity issue is not taxable income to the company. The proceeds are a capital contribution from shareholders, not business revenue. That is one of the core advantages of equity financing over alternatives like asset sales or licensing deals, which do produce taxable income.
For investors, two Internal Revenue Code provisions can matter. Section 1202 offers a federal capital gains exclusion on qualified small business stock. For shares issued on or after July 5, 2025, the issuing corporation must have gross assets of $75 million or less at issuance, and at least 80% of its assets must be used in an active trade or business. Hold the stock for at least five years, and up to 100% of the gain on sale can be excluded from federal income tax, subject to a per-issuer cap of $15 million in excluded gains. Both the asset limit and the gain cap begin adjusting for inflation in 2027. The company must be a domestic C corporation in an eligible industry; services like consulting, law, financial services, and hospitality are generally excluded, and the stock must be acquired directly from the corporation rather than on the secondary market.
Section 1244 works in the opposite direction. If stock in a qualifying small corporation becomes worthless or sells at a loss, the shareholder can treat up to $50,000 of the loss as an ordinary deduction, or $100,000 on a joint return, rather than a capital loss.13Office of the Law Revision Counsel. 26 USC 1244 Ordinary losses offset regular income dollar for dollar, while capital losses are capped at $3,000 per year against ordinary income. For investors in startups, that distinction can save thousands if the company fails.
Legal Liability and Resale Rules
The registration statement is the most consequential document in any public offering, and the law treats errors in it strictly. Section 11 of the Securities Act creates civil liability for any material misstatement or omission in a registration statement at the time it becomes effective.14Office of the Law Revision Counsel. 15 USC 77k – Civil Liabilities on Account of False Registration Statement The company is strictly liable; investors need only show a material error, not any intent to mislead. Liability also extends to everyone who signed the statement, every director at the time of filing, every underwriter, and any accountant or expert who prepared or certified part of it. Directors and underwriters can escape by proving they conducted reasonable due diligence, but only if they can show they actually investigated.
Selling without a registration statement or a valid exemption is itself a violation, and investors who bought unregistered securities can demand their money back through rescission.6Office of the Law Revision Counsel. 15 USC 77e – Prohibitions Relating to Interstate Commerce and the Mails
Shares acquired in a private placement or as compensation count as restricted securities and cannot be resold freely. Rule 144 sets the conditions. If the issuer files regular SEC reports, the holder waits at least six months before selling. If the issuer does not file, the holding period is one year. Affiliates — officers, directors, and large shareholders — face additional limits even after the holding period expires. They can sell no more than the greater of 1% of outstanding shares or the average weekly trading volume over the prior four weeks in any three-month period, and they must file Form 144 with the SEC if a sale exceeds 5,000 shares or $50,000 in value.15U.S. Securities and Exchange Commission. Rule 144: Selling Restricted and Control Securities
Ongoing Reporting After Going Public
An equity issue that takes a company public is a one-time event. The reporting obligations that follow are permanent for as long as the company stays public. The SEC requires annual reports on Form 10-K, quarterly reports on Form 10-Q, and current reports on Form 8-K whenever a significant event happens, such as an executive departure, a major acquisition, or a material change in financial condition.16U.S. Securities and Exchange Commission. Ready to Go Public Deadlines tighten for larger companies. Missing them can trigger SEC enforcement, loss of eligibility for shelf registration on Form S-3, and an immediate hit to investor confidence that often shows up in the stock price.
