Follow-on and secondary offerings are methods companies use to raise additional capital after their initial public offering (IPO). Understanding the differences between these offerings, who sells the securities, and where the proceeds go is essential for the SIE exam. These offerings occur in the primary market when new or additional securities are sold to raise funds.
A follow-on offering (also called a subsequent public offering or additional public offering) occurs when a company that is already publicly traded issues and sells additional shares to the public. The company itself is the seller, and the proceeds go directly to the company's treasury to fund operations, expansion, debt repayment, or other corporate purposes.
This is a primary market transaction because new securities are being created and sold, with capital flowing to the issuing company. The company increases its total number of outstanding shares, which dilutes existing shareholders' ownership percentages.
A secondary offering is when existing shareholders (not the company) sell their shares to the public. Common sellers include company founders, early investors, venture capitalists, private equity firms, or other large shareholders who want to liquidate their positions. The company does not receive any proceeds-all money goes to the selling shareholders.
Despite the name "secondary," this is still considered a primary market transaction when it involves a formal public offering with SEC registration. The term "secondary" refers to the fact that these are already-issued securities being sold by secondary parties (not the issuer), not that it occurs in the secondary market.
A combined offering includes both newly issued shares from the company (primary component) and existing shares sold by current shareholders (secondary component). Both the company and selling shareholders receive proceeds from their respective portions of the offering.

All three offering types require SEC registration unless an exemption applies. Companies typically use Form S-1 (full registration) or Form S-3 (shelf registration for seasoned issuers). A prospectus must be provided to investors before or at the time of sale.
Dilution occurs only when new shares are created and issued, reducing each existing shareholder's proportional ownership of the company. In a follow-on offering, if a company has 1,000,000 shares outstanding and issues 200,000 new shares, each existing shareholder's ownership percentage decreases by approximately 16.7%.
Calculate dilution impact:
Original ownership = \(\frac{1 \text{ share}}{1,000,000 \text{ total shares}}\) = 0.0001%
After offering = \(\frac{1 \text{ share}}{1,200,000 \text{ total shares}}\) = 0.0000833%
Dilution = \(\frac{200,000}{1,200,000}\) = 16.7% reduction in ownership percentage
1. Scenario: A question asks where the proceeds go when a publicly traded company announces an offering of 5 million shares, with 3 million newly issued shares and 2 million shares sold by the CEO and other executives.
Correct Approach: This is a combined offering. The company receives proceeds from the 3 million newly issued shares, and the CEO and executives receive proceeds from the 2 million existing shares they're selling.
Check first: Identify whether new shares are being created (primary component) and whether existing shareholders are selling (secondary component).
Do NOT do first: Do not assume all proceeds go to the company just because it's a public offering announcement. Many students miss the secondary component when both types are present.
Why other options are wrong: Saying all proceeds go to the company ignores the secondary component; saying all proceeds go to selling shareholders ignores the newly issued shares; saying it's only a follow-on or only a secondary offering ignores that both components exist in a combined offering.
2. Scenario: An exam question asks about dilution impact when a company with 10 million shares outstanding conducts an offering where existing shareholders sell 2 million shares to the public.
Correct Approach: No dilution occurs. This is a secondary offering where existing shares are sold, so total outstanding shares remain at 10 million.
Check first: Determine whether new shares are being created or existing shares are being sold.
Do NOT do first: Do not calculate dilution percentages for secondary offerings. Students commonly confuse any public offering with dilution, but dilution only occurs when new shares are issued.
Why other options are wrong: Any answer indicating dilution or ownership percentage change is incorrect because no new shares are created; the total shares outstanding remains constant when existing shareholders sell their holdings.
3. Scenario: A question describes a company that completed its IPO 120 days ago and now announces that venture capital investors are selling their shares to the public. The question asks what type of offering this represents.
Correct Approach: This is a secondary offering. The venture capital investors are existing shareholders selling their shares after the typical lock-up period (90-180 days) has expired.
Check first: Identify whether the company or existing shareholders are selling, and note the timing relative to the IPO and lock-up expiration.
Do NOT do first: Do not confuse this with a follow-on offering just because it occurs after an IPO. The key is who is selling-existing shareholders, not the company issuing new shares.
Why other options are wrong: A follow-on offering would involve the company issuing new shares; an IPO is the initial offering, not subsequent sales; a combined offering would require both the company and shareholders to be selling.
4. Scenario: An exam question presents a situation where a company needs capital for a major acquisition and announces an offering of newly issued shares.
Correct Approach: This is a follow-on offering. The company is issuing new shares to raise capital for corporate purposes (the acquisition).
Check first: Identify the purpose of the offering and who needs the capital-if the company needs funds for operations, expansion, or acquisitions, it must be issuing new shares.
Do NOT do first: Do not select secondary offering just because the company is already public. Secondary offerings provide capital to selling shareholders, not the company.
Why other options are wrong: A secondary offering wouldn't raise capital for the company; an IPO already occurred since the company is already public; a combined offering would require existing shareholders to also be selling, which isn't mentioned.
5. Scenario: A question asks what happens to earnings per share (EPS) when a company conducts an offering where both the company issues 1 million new shares and existing shareholders sell 500,000 shares.
Correct Approach: EPS decreases because the 1 million newly issued shares increase the total shares outstanding (denominator in EPS calculation). The 500,000 shares sold by existing shareholders don't affect EPS since they're already counted in outstanding shares.
Check first: Separate the primary component (new shares affecting EPS and dilution) from the secondary component (existing shares with no EPS or dilution impact).
Do NOT do first: Do not add all 1.5 million shares together when calculating dilution or EPS impact. Only newly issued shares change the outstanding share count.
Why other options are wrong: Saying EPS increases is incorrect because more shares outstanding means lower EPS; saying EPS is unaffected ignores the 1 million new shares; using 1.5 million shares to calculate the EPS impact incorrectly includes shares that were already outstanding.
Task: Determining the type of offering and who receives proceeds
Task: Calculating dilution from a follow-on or combined offering
Q1: A publicly traded company announces that it will sell 2 million newly issued shares to raise capital for expansion, while the CEO and CFO will sell 1 million of their existing shares. Who receives the proceeds from this offering?
(a) All proceeds go to the company
(b) All proceeds go to the CEO and CFO
(c) The company receives proceeds from 2 million shares; the CEO and CFO receive proceeds from 1 million shares
(d) Proceeds are split equally among the company, CEO, and CFO
Ans: (c)
This is a combined offering with both primary (2 million new shares) and secondary (1 million existing shares) components. The company receives proceeds from the newly issued shares, and the selling executives receive proceeds from their shares. Option (a) ignores the secondary component; option (b) ignores the primary component; option (d) incorrectly suggests equal splitting rather than allocating proceeds based on who is selling what.
Q2: A company with 20 million shares outstanding completes a follow-on offering of 5 million newly issued shares. What is the approximate dilution effect on existing shareholders?
(a) 10%
(b) 15%
(c) 20%
(d) 25%
Ans: (c)
New total outstanding shares = 20 million + 5 million = 25 million. Dilution = 5 million ÷ 25 million = 0.20 or 20%. Each existing shareholder's ownership percentage decreases by 20%. Option (a) incorrectly uses 5 million ÷ 20 million × 50%; option (b) is miscalculated; option (d) incorrectly uses 5 million ÷ 20 million = 25%.
Q3: Which statement is TRUE about a secondary offering?
(a) The issuing company receives all proceeds from the sale
(b) New shares are created, causing dilution for existing shareholders
(c) Existing shareholders sell their shares, and they receive the proceeds
(d) The company's total outstanding shares increases
Ans: (c)
In a secondary offering, existing shareholders sell their shares and receive the proceeds. The company receives no proceeds. No new shares are created, so no dilution occurs and total outstanding shares remains unchanged. Options (a), (b), and (d) all describe characteristics of a follow-on offering, not a secondary offering.
Q4: Three months after a company's IPO, the lock-up period expires and venture capital investors announce they will sell 3 million of their shares to the public. The company currently has 30 million shares outstanding. What is the impact on the company's total outstanding shares?
(a) Increases to 33 million shares
(b) Decreases to 27 million shares
(c) Remains at 30 million shares
(d) Changes based on the offering price
Ans: (c)
This is a secondary offering where existing shareholders (venture capital investors) are selling their shares after the lock-up period. No new shares are created, so the total outstanding shares remains 30 million. Option (a) incorrectly treats this as newly issued shares; option (b) incorrectly suggests shares disappear when sold; option (d) is incorrect because the number of outstanding shares doesn't depend on price.
Q5: A company announces a combined offering consisting of 4 million newly issued shares and 2 million shares sold by existing shareholders. The company has 40 million shares outstanding before the offering. What will be the new total outstanding shares after the offering?
(a) 40 million shares
(b) 42 million shares
(c) 44 million shares
(d) 46 million shares
Ans: (c)
Only newly issued shares increase the total outstanding shares. Starting with 40 million + 4 million newly issued = 44 million. The 2 million shares sold by existing shareholders were already part of the 40 million outstanding, so they don't increase the total. Option (a) ignores new shares; option (b) incorrectly adds only the secondary component; option (d) incorrectly adds both components (6 million).
Q6: What is the primary difference between a follow-on offering and a secondary offering?
(a) Follow-on offerings require SEC registration; secondary offerings do not
(b) Follow-on offerings involve the company issuing new shares; secondary offerings involve existing shareholders selling their shares
(c) Follow-on offerings occur only in the first year after IPO; secondary offerings occur later
(d) Follow-on offerings are always larger than secondary offerings
Ans: (b)
The fundamental difference is who is selling: in follow-on offerings, the company issues and sells new shares; in secondary offerings, existing shareholders sell their already-issued shares. Both require SEC registration, making option (a) wrong. Option (c) is incorrect because timing isn't the defining characteristic. Option (d) is incorrect because size varies and isn't a distinguishing feature.
