CaseMark Analyzing Follow On Offering Structures
When To Use
- Issuer is evaluating capital-raising alternatives after IPO (primary follow-on) or existing holders seek liquidity (secondary follow-on)
- Comparing execution strategies: overnight/block trade, marketed deal, at-the-market (ATM) program, or bought deal
- Quantifying dilution impact, pricing dynamics, and net proceeds under different structures
- Advising on timing, discount expectations, and lock-up considerations for a proposed offering
Inputs To Gather
- Issuer profile: current share price, market cap, average daily trading volume (ADTV), public float, and existing share count (basic and fully diluted)
- Offering parameters: target gross proceeds, primary vs. secondary split, selling shareholder identity and stake size
- Capital structure: outstanding convertible instruments, warrants, options, and anti-dilution provisions
- Market context: recent stock volatility (30/60/90-day), sector index performance, comparable recent follow-on transactions
- Regulatory status: shelf registration (S-3) availability, WKSI eligibility, Rule 144 holding periods for selling holders [VERIFY]
- Contractual constraints: existing lock-up agreements, registration rights obligations, co-sale or tag-along provisions
Workflow
Classify offering type and eligibility
- Determine if issuer qualifies as WKSI (public float ≥ $700M) or meets S-3 primary offering thresholds [VERIFY current SEC thresholds]
- Identify whether the offering is primary (new shares), secondary (existing holder selling), or a combination
- Check shelf registration capacity remaining and any SEC comment history
Structure comparison matrix
- Overnight/block trade: best for secondary sales of 3-8% of float; execution in hours; typical discount 3-5% to last close; minimal market impact if sized within ~25% of ADTV; no roadshow
- Marketed deal (1-2 day): suits $100M+ offerings requiring price discovery; 1-2 day bookbuild with limited marketing; discount typically 4-7%; anchor investor targeting
- Fully marketed deal: 5-10 day roadshow for larger or more complex stories; broadest investor reach; discount 5-8%; higher execution risk from market movement during marketing
- ATM program: best for programmatic issuance over weeks/months; sold at market with no fixed discount; minimal per-trade impact if daily sales kept under 10-15% of ADTV; lower gross spread (typically 1-2% vs. 3-5% for underwritten)
- Bought deal: bank commits firm capital at a fixed price; fastest certainty of execution; deepest discount (5-10%) to compensate underwriter risk; used when speed or price certainty is paramount
Dilution analysis
- Calculate basic dilution: new shares / (existing shares + new shares)
- Calculate fully diluted impact including in-the-money options, warrants, and convertibles using treasury stock method
- Model EPS dilution at target proceeds for each structure scenario
- Assess impact on existing holders' voting power and ownership percentage thresholds (e.g., 5%, 10%, 20% blockers)
Pricing and discount analysis
- Pull comparable precedent transactions: same sector, similar market cap, same offering type, last 12-24 months
- Compute median/mean file-to-offer discount, offer-to-close performance (day 1, 5, 30), and gross spread
- Adjust for current market volatility — wider discounts in high-vol environments
- Flag whether VWAP or last-close pricing is more appropriate given trading pattern
Net proceeds and cost comparison
- For each structure: gross proceeds – underwriting discount – estimated legal/accounting fees – SEC filing fees = net proceeds
- Compare all-in cost as percentage of gross proceeds across structures
- For ATM: model cumulative proceeds and weighted average sale price over projected selling period
Risk and timing assessment
- Market risk exposure: overnight (hours) vs. marketed (days) vs. ATM (weeks/months)
- Signaling risk: primary issuance may signal overvaluation; secondary may signal insider selling
- Regulatory timing: blackout periods around earnings, pending material events, Regulation M compliance [VERIFY]
- Lock-up implications for selling shareholders and new lock-up requirements for the issuer
Output
Deliver a structured analysis report containing:
- Executive summary: recommended offering structure with rationale (1-2 paragraphs)
- Structure comparison table: side-by-side matrix of each offering type with columns for typical discount, execution timeline, spread, marketing requirement, and suitability assessment
- Dilution impact table: basic and fully diluted share counts, EPS impact, and ownership percentage changes at target proceeds
- Precedent transaction summary: 5-10 comparable deals with key metrics (issuer, date, size, discount, aftermarket performance)
- Net proceeds waterfall: gross proceeds to net proceeds bridge for each structure
- Risk matrix: key risks by structure type with likelihood and mitigation strategies
- Recommendation: preferred structure with supporting rationale, including backup alternative if market conditions shift
Quality Checks
- Verify share counts against most recent 10-Q/10-K and any subsequent 8-K filings reporting option exercises or conversions
- Confirm S-3 eligibility and remaining shelf capacity from the most recent shelf registration statement [VERIFY]
- Cross-check precedent discount data against actual pricing supplements (424B filings), not press releases alone
- Validate ADTV figures using a consistent 30-day lookback from the analysis date
- Ensure dilution calculations account for all convertible instruments, not just common shares outstanding
- Flag any reliance on stale data (>5 trading days old for market data, >1 quarter for financials) with [VERIFY]
- Confirm that ATM projections use realistic daily volume participation assumptions (typically 10-25% of ADTV ceiling)
