What is a typical sell-side M&A process?
A sell-side M&A process involves preparation (teaser, CIM, valuation), a first round (teasers, NDAs, IOIs), a second round (data room, management presentations, LOIs), negotiation and signing of a definitive agreement, and closing after regulatory approvals.
Intuition
The process is structured as a funnel to maximize competitive tension while maintaining confidentiality. Each round filters buyers by seriousness and price, forcing them to commit more resources and offer higher valuations to stay in the process. The banker's core job is to create a controlled auction dynamic that drives the best outcome for the seller.
Watch
Interviewers may ask how a sell-side process differs from a buy-side process. Key difference: on the sell-side, the banker runs the auction and controls information flow; on the buy-side, the banker helps one client evaluate a target, build models, and structure a competitive bid. Also watch for the distinction between IOIs (non-binding, Round 1) and LOIs (submitted in Round 2 and generally non-binding overall, though certain provisions such as exclusivity and confidentiality may be binding) — candidates frequently confuse these.
Deep Dive
Describe the end-to-end process an investment bank runs when representing a seller in an M&A transaction.
Phase 1 — Preparation (Weeks 1–4)
- Engage sell-side advisor; sign engagement letter
- Conduct due diligence on the seller's own business (vendor/sell-side DD)
- Build financial model and preliminary valuation (DCF, comps, precedent transactions)
- Prepare marketing materials:
- Teaser (anonymous 1-pager to gauge interest)
- Confidential Information Memorandum (CIM) (detailed 30–50 page book)
- Compile buyer universe list — strategic buyers + financial sponsors, tiered by fit
Phase 2 — First Round (Weeks 5–10) 6. Send teasers to broad buyer list 7. Interested parties sign NDAs (non-disclosure agreements) 8. Distribute CIM to NDA-signed parties 9. Buyers submit Indications of Interest (IOIs) — non-binding, include preliminary valuation range, financing plan, high-level structure 10. Seller and advisor evaluate IOIs, narrow to shortlist (typically 3–8 buyers)
Phase 3 — Second Round (Weeks 11–18) 11. Open virtual data room (VDR) to shortlisted buyers with detailed financial, legal, commercial data 12. Host management presentations — seller's management meets each shortlisted buyer 13. Buyers conduct detailed due diligence (financial, legal, tax, commercial, environmental) 14. Distribute draft merger/purchase agreement to buyers 15. Buyers submit Letters of Intent (LOIs) or final bids — typically non-binding overall, but include definitive price, markup of purchase agreement, financing approach or commitments, timeline to close, and key conditions
Phase 4 — Negotiation & Signing (Weeks 19–22) 16. Select preferred bidder (may run parallel negotiations with 1–2 runners-up for leverage) 17. Negotiate final purchase agreement terms — reps & warranties, indemnities, escrow/holdback, earnouts, conditions to close 18. Buyer delivers committed financing letters (if debt-funded) 19. Sign definitive agreement; announce transaction publicly
Phase 5 — Closing (Weeks 23–30+) 20. Obtain regulatory approvals (antitrust/HSR, sector-specific) 21. Obtain shareholder approval if required (public target) 22. Satisfy all closing conditions 23. Close — funds transfer, ownership changes hands 24. Banker collects success fee (typically 1–2% of enterprise value; fee scales inversely with deal size)
Key Deliverables Summary:
| Phase | Key Output |
|---|---|
| Preparation | Teaser, CIM, buyer list, valuation |
| First Round | IOIs received and evaluated |
| Second Round | Management presentations, LOIs/final bids |
| Negotiation | Signed definitive agreement |
| Closing | Regulatory clearance, funds transfer |
Total timeline is illustrative: a typical auction runs 4–9 months from engagement to close, depending on deal complexity and regulatory hurdles. Targeted (non-auction) processes with a single buyer can compress significantly but sacrifice competitive tension on price.
