Introduction
The product set covered in this section (marketed follow-ons, overnight bought deals, block trades, ATM programs, rights offerings, ASR programs, and secondary offerings) gives ECM bankers a comprehensive toolkit for post-IPO equity issuance, but the live skill is in choosing which product clears optimally for a specific mandate. The choice is driven by four primary inputs the banker evaluates in real time: who is selling, how much, on what timeline, and into what investor base. This article walks through the decision framework as ECM bankers actually apply it in client meetings, integrating the structures from the prior articles into a coherent product-selection logic.
- Bake-Off (in Follow-On Context)
The competitive process by which an issuer selects banks for a follow-on or block-trade mandate. Unlike the IPO bake-off (which assesses banks across coverage, distribution, and research), the follow-on bake-off is typically faster (days rather than weeks), more focused (often a single product structure), and weighted heavily toward the bank's specific track record on the relevant product type. Sponsor sell-down bake-offs frequently weight the IPO lead's institutional knowledge of the issuer heavily and can be largely a confirmation of incumbency rather than a genuine open competition.
The Banker's Decision Process
Before applying the four inputs, the banker runs a recognizable sequence to scope the mandate and structure the recommendation.
Initial Client Conversation
CFO or treasurer raises capital need (acquisition funding, growth capex, sponsor liquidity, balance-sheet repair). Banker captures size, urgency, and proceeds use.
Internal Working-Group Setup
Senior coverage banker, ECM head, syndicate desk, and equity derivatives desk align on initial product hypothesis and run trading-data screens.
Borrow and Liquidity Screen
Syndicate desk pulls borrow market data, recent trading patterns, and ADV statistics to test which products are operationally viable.
Investor-Base Mapping
Sales coverage maps the issuer's institutional base, recent buying activity, and any large concentrated positions that could affect supply absorption.
Product Recommendation Formed
Coverage banker presents the product recommendation (with one or two alternatives) to the issuer's CFO and board, with discount estimates and timing.
Mandate Awarded or Bake-Off Run
Issuer either awards the mandate sole-source or runs a confidential bake-off among 2-4 banks for the proposed structure.
Execution and Pricing
Selected bank or banks execute the chosen product through the relevant timeline (overnight, days, or continuous).
The Four Inputs
The banker evaluates four inputs in roughly this order when scoping a contemplated transaction.
Input 1: Who Is Selling
The first question is whether the seller is the issuer (raising primary capital) or an existing holder (monetizing a stake through a secondary transaction). Issuer sales open the full primary product set: marketed follow-ons, bought deals, ATM programs, and rights offerings. Selling-shareholder transactions narrow the set: pure secondary offerings typically clear as marketed follow-ons or block trades, while ATMs and rights offerings are not available to selling shareholders. Mixed primary/secondary structures combine both categories under a single offering.
Input 2: Transaction Size
The second question is the size of the contemplated transaction relative to typical daily trading volume (ADV) and in absolute dollar terms. Transactions under 10 percent of trailing 30-day ADV typically clear comfortably as block trades or overnight bought deals; transactions of 10 to 25 percent of ADV usually require a marketed follow-on for orderly execution; transactions over 25 percent of ADV may need to fragment across multiple tranches or use an ATM program to spread the issuance over weeks. In absolute dollar terms, very small transactions (under $50 million) often clear as opportunistic block trades; very large transactions (over $1 billion) almost always run marketed because the marketing window is needed to assemble enough institutional demand.
Input 3: Urgency and Timing
The third question is how time-sensitive the transaction is. Issuers facing binary catalysts (pending earnings, M&A announcements, regulatory deadlines) cannot afford the multi-day exposure of a marketed follow-on and typically pivot to bought deals or block trades for execution certainty. Issuers with flexible timing and no near-term catalysts capture the tighter pricing of the marketed format. Sponsors monetizing post-lockup positions are typically opportunistic on timing and use blocks to pick favorable trading windows over months.
Input 4: Investor-Base Depth
The fourth question is the depth of the issuer's existing institutional investor base and recent buying behavior. Issuers with deep, established institutional relationships and recent post-IPO supply absorption can clear larger transactions through any format with relatively tight pricing. Issuers with thin institutional bases or limited recent buying activity typically need the marketed format's compressed roadshow to refresh investor familiarity, even at the cost of additional execution risk and time.
- Investor-Base Depth
A qualitative measure of an issuer's existing institutional shareholder base used to evaluate which follow-on products will execute cleanly. Depth is assessed across number of long-only institutional holders (typically 50+ for a clean marketed follow-on), recent post-IPO supply absorption (whether prior follow-ons cleared at tight discounts), peer-set positioning of major holders (do similar institutional investors hold peer companies), and concentration risk (whether one or two holders dominate the base). Issuers with deep bases can run almost any structure efficiently; issuers with thin bases face wider discounts and longer marketing windows regardless of which product is chosen.
The Decision Matrix
Applying the four inputs in combination produces a recognizable decision matrix.
| Scenario | Recommended Product | Reasoning |
|---|---|---|
| Issuer raising capital, time-sensitive, smaller size | Overnight bought deal | Bank takes principal risk, single overnight execution |
| Issuer raising capital, larger size, flexible timing | Marketed follow-on | Compressed roadshow extracts tighter pricing |
| Issuer with frequent recurring needs | ATM program | Continuous dribble-out matches recurring capital |
| PE sponsor monetizing post-lockup, smaller size | Block trade | BWIC produces firm price overnight |
| PE sponsor monetizing post-lockup, larger size | Marketed secondary follow-on | Multi-day window absorbs the supply |
| Issuer in distress or stressed multiple | Rights offering or PIPE | Pre-emption preserves shareholders, lower marketing intensity |
| Issuer with active buyback intent | ASR program | Bank takes borrow risk, immediate EPS uplift |
Common Multi-Product Pathways
Sophisticated mandates frequently sequence multiple products over time. A sponsor exiting a post-IPO position might run an initial marketed follow-on at the 2-year mark to establish institutional support, then transition to block trades for subsequent sell-downs as the position size shrinks. An issuer with recurring capital needs might maintain an ATM program for routine issuance and execute a discrete marketed follow-on for a specific large funding event such as an acquisition closing. The product framework is not "pick one and stick with it"; it is a continuously evolving choice as the issuer's situation evolves.
How 2025 Market Dynamics Shape the Choice
The current market environment has shifted the relative weight bankers place on each input.
Heightened Volatility Favors Speed
Equity market volatility spiked sharply in early 2025 (the VIX touched roughly 60 on April 7, 2025 amid tariff-driven turmoil) before easing later in the year, leaving 2025's average level meaningfully above 2024's calmer ~15.5 baseline and creating elevated overnight execution risk on marketed transactions. The volatility shift has pushed the banker decision framework slightly toward bought deals and blocks (where the bank takes the overnight risk) rather than marketed structures (where the issuer holds the risk). 2025 saw overnight offerings account for more than half of total follow-on activity, reflecting issuer and sponsor preferences to limit multi-day market exposure.
Sponsor Monetization Pressure
Roughly 35 percent of 2025 follow-on offerings included a secondary component, above the 5-year median of 24 percent, reflecting sponsors' accelerated monetization of stalled exits. The pattern has shifted product mix toward block trades and mixed primary/secondary follow-ons because sponsors are more frequently the marginal seller in any given mandate.
Larger Issuer Profile
The average 2025 IPO market cap of approximately $4 billion at pricing has produced a follow-on universe skewed toward larger seasoned issuers with deeper institutional bases. The skew supports the marketed format's continued strength because larger issuers can absorb the multi-day execution window that smaller issuers struggle with. The cohort of issuers entering the post-lockup secondary cycle in 2026 is materially larger and more institutionally established than any prior vintage, which is structurally bullish for both the marketed and block formats over the next 18 to 24 months.
Convertible Issuance as a Complement
Convertibles posted their strongest momentum since the pre-financial-crisis era in 2025, and many issuers now consider convertibles alongside straight follow-ons as part of an integrated capital-raise framework. The product-choice framework increasingly extends beyond pure-equity follow-ons to include the convertible as a hybrid alternative when the issuer is willing to trade some equity dilution and embedded optionality for a lower coupon and reduced near-term shareholder dilution.
Who is selling, how much, on what timeline, into what investor base: those four inputs run through the bake-off, the borrow screen, the investor-base map, and out the other side as a product recommendation that clears optimally for the specific mandate at hand. With the pure-equity toolkit now mapped end to end, the natural next category is the equity-flavored debt instruments that increasingly sit alongside follow-ons on the same product slate. Convertible bonds and equity-linked products open Section 5.
