Equity capital market deals, usually shortened to ECM deals, are transactions in which a company raises money by selling ownership stakes to investors. The shares sold can be newly issued by the company or existing shares offloaded by current holders, and the buyers are usually a mix of institutional funds and retail investors reached through broker networks. Every public offering runs through a framework set by the Securities and Exchange Commission, and the full process, from hiring bankers to settling shares, usually takes three to six months.
The structure a company picks depends on whether it is already public, how fast it needs the money, how much dilution it can accept, and which investors it wants on the register. The sections below walk through the main deal types, how the pricing and selling actually work, the timeline, and what changes for the company and its insiders once the offering closes.
The Main Types of ECM Deals
Initial Public Offerings
An IPO is the first sale of a private company’s stock to the public. It converts a private business into a publicly traded one, which triggers an ongoing obligation to file annual, quarterly, and current reports with the SEC.1Securities and Exchange Commission. Exchange Act Reporting and Registration The company files a registration statement describing its business, the securities being offered, its management, and audited financial statements.2U.S. Securities and Exchange Commission. Public Companies
For founders and early investors, the IPO is often the first real chance to turn paper wealth into cash, though lock-up agreements usually delay that liquidity for months after pricing. For the company, proceeds fund operations, pay down debt, or finance acquisitions. The trade-off is continuous disclosure, activist pressure, and a visible stock price that pulls management toward short-term earnings.
Follow-On Offerings
Companies already trading on an exchange raise more capital through follow-on offerings, which come in two forms. In a primary follow-on, the company issues brand-new shares and keeps the proceeds, which dilutes existing shareholders because the same company value is now split across more shares. In a secondary follow-on, existing shareholders sell shares they already own, and no money flows to the company at all. The share count stays flat, so there is no dilution, but a large insider sale can signal that knowledgeable holders want out. Many deals combine both: the company issues new shares while insiders simultaneously sell part of their holdings.
At-the-Market Offerings
An at-the-market, or ATM, offering lets a public company sell new shares gradually into the existing trading market at prevailing prices, rather than in one block at a fixed price. Federal regulations define an ATM offering as a sale of equity securities into an existing trading market at other than a fixed price, and require the company to have an effective shelf registration on Form S-3.3eCFR. 17 CFR 230.415 – Delayed or Continuous Offering and Sale of Securities A broker-dealer drips the shares out over days or weeks, keeping the price impact small. ATMs suit companies that want flexible, ongoing access to capital without the expense of a traditional marketed deal.
Rights Offerings
In a rights offering, the company gives existing shareholders the first chance to buy additional shares, usually at a discount to the current trading price. Each shareholder receives subscription rights in proportion to their current holdings. If the rights are transferable, shareholders who do not want more stock can sell their rights on the open market. If not, unused rights simply expire. A standby underwriter sometimes backstops the deal by agreeing to buy whatever shares existing holders decline.
Convertible Securities
Convertible bonds or preferred stock give investors a fixed-income instrument that can be exchanged for common shares at a predetermined price. The conversion feature lets the company pay a lower interest rate than straight debt would require, and investors accept the lower yield in exchange for upside if the stock climbs above the conversion price. Immediate dilution is avoided because conversion only happens if the stock rises enough to make it worthwhile. Growth-stage companies often favor convertibles when they believe their stock is temporarily undervalued and issuing common shares outright would give away too much ownership. The conversion price and ratio are locked in at issuance.
Private Investments in Public Equity
A PIPE deal sells stock or convertible securities directly to a small group of institutional or accredited investors, usually at a discount to the market price. PIPEs close much faster than registered public offerings because they skip the marketing and roadshow process. The shares are initially unregistered and carry resale restrictions, though the company typically agrees to file a registration statement covering them shortly after closing. PIPEs suit smaller public companies that need capital quickly or larger ones facing hostile market conditions. The discount compensates investors for holding restricted stock during the registration period.
Direct Listings
A direct listing lets a company begin trading on a public exchange without using underwriters and, in the original form, without issuing new shares. Existing shareholders sell their holdings directly to the public on the first day of trading. The SEC approved a NYSE rule that also permits companies to raise primary capital through a direct listing, with the company selling new shares in the opening auction on its first trading day.4U.S. Securities and Exchange Commission. Statement on Primary Direct Listings Without underwriters, there is no guaranteed capital raise, no price stabilization in aftermarket trading, and no lock-up on insider sales. Companies that go this route are usually well-known brands with enough natural demand that they do not need a bank to drum up interest, and they save millions in underwriting fees.
How Underwriters Price and Sell the Deal
Investment banks sit at the center of most ECM deals, bridging the company that wants to sell equity and the investors willing to buy it. The type of commitment the bank makes determines who bears the risk if the market cools between pricing and settlement.
Firm Commitment vs. Best Efforts
Under a firm commitment, the bank agrees to buy every share in the offering from the company at a negotiated price, then resells those shares to investors at a slightly higher price. If demand falls short, the bank eats the loss. This guarantees the company a specific dollar amount at closing. The difference between what the bank pays the company and what it charges investors is the underwriting spread, which is the bank’s primary compensation.
For IPOs raising up to about $200 million, a gross spread of exactly 7% is remarkably standard. Among IPOs in that size range between 2001 and 2025, over 86% carried a spread of precisely 7%. Larger deals get much better economics: IPOs raising $1 billion or more averaged roughly 4.4%, and mega-deals by companies like Visa, General Motors, and Facebook have seen spreads as low as 0.75% to 2.8%.5Warrington College of Business. Initial Public Offerings: Underwriting Statistics Through 2025 Follow-on offerings by large, established companies generally carry lower spreads than IPOs because the company already has a public track record and a liquid market.
A less common alternative is the best efforts commitment, where the bank only agrees to try to sell the shares. If demand is weak, the company simply raises less. A variation called all-or-none cancels the whole deal if a minimum number of shares cannot be placed. Both structures push market risk back onto the company and show up more often in smaller or speculative offerings.
The Syndicate
Large offerings are rarely handled by a single bank. The lead underwriter forms a syndicate, a temporary group of investment banks that share financial exposure and bring their own distribution networks. The lead bookrunner runs the deal, managing registration, coordinating due diligence, and building the order book. Co-managers help sell shares and take a smaller cut of the fees. The structure gets the offering in front of the widest possible base of institutional investors across geographies and investment styles.
FINRA reviews the compensation terms of every public offering before shares can be distributed and must issue an opinion that the terms are not unfair or unreasonable.6FINRA. Corporate Financing Rule – Underwriting Terms and Arrangements Member firms file the engagement letter, the underwriting agreement, and an estimate of the maximum value of each item of compensation before marketing begins.
Book-Building and Pricing
The core pricing mechanism is book-building, which runs in parallel with the roadshow. Underwriters collect non-binding indications of interest from institutional investors: how many shares they want and at what price. The orders build a demand curve that shows the bookrunner where appetite concentrates. An oversubscribed book gives the company leverage to price at the top of the range. A soft book means the price drops or the deal gets restructured.
The starting point for any price discussion is where comparable public companies trade, using metrics like price-to-earnings ratios, enterprise-value-to-revenue multiples, or industry-specific benchmarks. Comparables only set the neighborhood. The actual price is pushed up or down by the company’s growth trajectory, management credibility, market conditions at pricing, and the depth of demand revealed during book-building. The company and bookrunner negotiate the final number on the night before trading begins.
Allocation
Once the price is locked, the bookrunner decides who gets shares. The bookrunner segments orders by investor type and quality. A hundred million dollars from a long-term mutual fund manager carries more weight than the same amount from a hedge fund likely to flip on day one. Long-term institutional investors who gave useful feedback during the roadshow get priority. Investors seen as likely to sell quickly get cut back or shut out, even if they bid aggressively. Retail investors, who typically participate through broker-dealers in the syndicate, generally get a smaller piece.
Smart allocation creates mild scarcity, which tends to produce a modest first-day price increase. A 10% to 15% pop is generally viewed as healthy. A 50% pop means the company gave away too much value. A first-day decline damages the underwriter’s reputation and makes future deals harder.
The Greenshoe Option
Nearly every underwritten offering includes an overallotment option, known as the greenshoe, which lets the underwriters buy up to an additional 15% of the offering from the company.6FINRA. Corporate Financing Rule – Underwriting Terms and Arrangements The 15% cap is set by FINRA rules. In practice, the underwriters initially sell more shares than the base offering size, creating a short position. If the stock drops below the offering price, they buy shares in the open market to cover that short, which supports the price. If the stock trades above the offering price, they exercise the greenshoe to buy additional shares from the company at the offering price, covering their short while raising more capital for the issuer.7U.S. Securities and Exchange Commission.

The Timeline From Engagement to Closing
Engagement and Due Diligence
The process begins when the company picks a lead bookrunner and signs an engagement letter defining the scope of work, the underwriting structure, and the anticipated spread. That triggers full due diligence, during which the underwriters and their lawyers go through financial records, material contracts, pending litigation, and regulatory compliance. The reason runs deeper than thoroughness. Under the Securities Act of 1933, underwriters face personal liability if the registration statement contains material misstatements or omissions.8Office of the Law Revision Counsel. 15 USC 77k – Civil Liabilities on Account of False Registration Statement The only way an underwriter escapes that liability is by proving, after a reasonable investigation, that it had reasonable grounds to believe the statements were true. That due diligence defense is what makes the whole investigation worth its cost.
Before closing, the underwriters obtain a comfort letter from the company’s independent auditors verifying specific financial data in the registration statement, which fills a gap in the underwriter’s liability protection.9Public Company Accounting Oversight Board. AS 6101: Letters for Underwriters and Certain Other Requesting Parties
Registration Statement and SEC Review
The legal teams draft the registration statement, which includes a prospectus describing the business, financial condition, risk factors, and offering terms. The document is filed with the SEC, and under the Securities Act, no securities can be sold until the registration statement is effective.10Office of the Law Revision Counsel. 15 USC 77e – Prohibitions Relating to Interstate Commerce and the Mails Initial filings can be submitted confidentially, and the SEC has expanded the availability of nonpublic review for draft registration statements, though the company must publicly file all materials at least 15 days before any roadshow.11U.S. Securities and Exchange Commission. Enhanced Accommodations for Issuers Submitting Draft Registration Statements SEC staff issue comment letters requesting clarification or additional disclosure, the company responds with amendments, and the back-and-forth can take several rounds. The process ends when the SEC declares the registration statement effective.
The Quiet Period
From the time the company begins preparing its registration statement through the effective date, federal securities laws tightly restrict public statements by the company and the underwriters. This stretch is commonly called the quiet period, though the term is not formally defined in the statutes. The concern is “gun-jumping,” where premature communications could condition the market and give certain investors an unfair informational advantage.12Investor.gov. Quiet Period Limited safe harbors exist: communications made more than 30 days before filing are generally permissible, provided they do not reference the specific securities offering and come from the issuer itself.13Legal Information Institute. Pre-Filing Period
The Roadshow
Once SEC review is nearing completion, senior management hits the road, meeting institutional investors in presentations over one to two weeks. The roadshow is equal parts sales pitch and price discovery. Management presents strategy, competitive position, and financial projections, and investors reveal how much stock they would buy and at what price. These meetings rely on the preliminary prospectus, commonly called the “red herring” because it contains everything except the final price and share count.
Pricing and Closing
The final price is set late on the evening before shares begin trading, following negotiation between the company and the lead bookrunner based on the demand gathered during the roadshow. The final prospectus, with confirmed price and volume, goes out immediately. At closing, funds transfer from the underwriters to the company, and the shares are delivered. The gap between pricing and settlement is typically only a few business days.
Shelf Registration for Repeat Issuers
Companies that expect to tap the capital markets repeatedly can skip the full registration process each time by using a shelf registration under Rule 415. A single registration statement covers securities the company plans to sell over time, and shares can be pulled “off the shelf” when market conditions are favorable without going back for a new review. Securities offered through an ATM program, for example, must be registered under a shelf on Form S-3.3eCFR. 17 CFR 230.415 – Delayed or Continuous Offering and Sale of Securities
Not every company qualifies. To use Form S-3, a company must have been a reporting company for at least 12 months, filed all required reports on time during that period, and must not have defaulted on debt payments or missed preferred stock dividends.14Securities and Exchange Commission. Form S-3 Registration Statement Under the Securities Act of 1933 Well-known seasoned issuers, the largest and most established public companies, get an even faster lane: their shelf registrations become effective automatically on filing, with no SEC review at all. A company with an effective shelf can launch a follow-on in days rather than months, which means raising capital when markets are receptive instead of scrambling during a window that may have already closed.
Exchange Listing Requirements
Going public is not only about SEC registration. The company must also meet the listing standards of whichever exchange it wants to trade on. The NYSE, for example, requires at least 400 round-lot shareholders (each holding 100 shares or more), a minimum of 1.1 million publicly held shares, and at least $100 million in market value of those publicly held shares. The stock price must be at least $4.00 per share at the time of listing.15New York Stock Exchange. Overview of NYSE Initial Listing Standards
The NYSE also imposes financial tests. Under the earnings test, a company must have earned at least $10 million in aggregate pre-tax income over the three most recent fiscal years, with each year above zero and at least $2 million in each of the two most recent years. Companies that cannot meet the earnings test can qualify under a global market capitalization test requiring $200 million in market cap.15New York Stock Exchange. Overview of NYSE Initial Listing Standards Nasdaq has its own tiers. Meeting these standards is a prerequisite for the IPO, and maintaining them afterward is an ongoing obligation. Falling below the minimums can trigger delisting.
Life After the Offering
Lock-Up Periods
In virtually every IPO, insiders (founders, executives, and pre-IPO investors) agree not to sell their shares for a set period after the offering. The standard lock-up is 180 days, though some deals include staggered or performance-based early release provisions. Lock-ups are contractual agreements between the insiders and the underwriters, not regulatory requirements. When a lock-up expires and a large block of shares suddenly becomes eligible for sale, the stock often drops as the market anticipates increased supply.
Insider Reporting Under Section 16
Federal securities laws require officers, directors, and anyone holding more than 10% of a class of the company’s stock to disclose their ownership and every transaction. A new insider must file a Form 3 within 10 days of becoming an insider. Any subsequent purchase or sale must be reported on Form 4 within two business days. Transactions that qualify for certain exemptions or were not previously reported are captured on an annual Form 5, due within 45 days after the company’s fiscal year ends.16U.S. Securities and Exchange Commission. Insider Transactions and Forms 3, 4, and 5
Rule 144 and Resale of Restricted Stock
Shares received in a PIPE, a pre-IPO investment, or through employee compensation are typically restricted securities that cannot be freely resold. Rule 144 provides the path for selling them if certain conditions are met. For a reporting company, the minimum holding period is six months from the date the shares were bought and fully paid for. For non-reporting companies, the holding period extends to one year.17U.S. Securities and Exchange Commission. Rule 144: Selling Restricted and Control Securities
Affiliates (officers, directors, and large shareholders) face additional volume limits even after the holding period expires. The number of shares an affiliate can sell in any three-month period cannot exceed the greater of 1% of the outstanding shares of the same class, or the average weekly trading volume over the four weeks before the sale.17U.S. Securities and Exchange Commission. Rule 144: Selling Restricted and Control Securities The limits prevent insiders from dumping large positions in ways that would crush the stock price.
Ongoing SEC Reporting
After the IPO, the company must file annual reports on Form 10-K (audited by independent accountants), quarterly reports on Form 10-Q, and current reports on Form 8-K within four business days of specified triggering events. The CEO and CFO must personally certify the financial information in each 10-K and 10-Q. All filings go through the EDGAR system and become publicly available immediately on submission.1Securities and Exchange Commission. Exchange Act Reporting and Registration
Tax Treatment of the Proceeds
One feature of ECM deals that catches people outside corporate finance off guard: the company issuing the stock does not owe tax on the proceeds. Under the Internal Revenue Code, a corporation does not recognize gain or loss when it receives money or property in exchange for its own stock, including treasury stock.18Office of the Law Revision Counsel. 26 USC 1032 – Exchange of Stock for Property The treatment applies to IPOs, follow-on offerings, and any other issuance of new shares. Issuing your own equity is not a sale of property in the usual sense, and Congress eliminated the possibility of corporations selectively recognizing gains or losses from trading in their own shares.
Shareholders who sell existing shares in a secondary offering are a separate matter. They recognize capital gains or losses on the difference between their sale price and their cost basis, with treatment depending on how long they held the shares and their individual tax situation. That is entirely distinct from the corporate-level tax neutrality of new share issuances.
