Originate, screen, approve, fund
Buy-side M&A and corporate development: thesis, origination, screening, IOI, LOI and exclusivity, diligence launch, IC approval, financing and pre-signing integration planning — with the eight structural ways the buy-side chain is not the sell-side chain reversed.
Who this is for
You are the buyer — a corp-dev lead, a holdco or search principal, a deal team — running a funnel of targets toward one signature, and most of your cost is the deals you correctly decline.
A buy-side acquisition process is not the sell-side chain run in reverse. The buyer runs a funnel — thesis, buy box, origination, screening, indication of interest, letter of intent, diligence launch, investment committee approval, financing, and pre-signing integration planning — where most of the cost sits in targets correctly declined. A sale moves one asset toward many buyers; a buy-side program moves many targets toward one signature.1,2,3

The seller runs one process on one asset. The buyer runs a portfolio of processes against a base rate and has to underwrite the ones that die. That single difference reshapes the whole sequence: origination becomes a permanent function with conversion math, screening is optimized for saying no cheaply, and approval becomes a written document for people who have never met the target. This hub is built on the buyer's decision sequence, not on a product's object model.
506(b) forbids general solicitation but lets you sell to up to 35 non-accredited purchasers on a reasonable-belief standard; 506(c) permits solicitation but requires that every purchaser be accredited and that the issuer take reasonable steps to verify it. The trade is advertising freedom against verification burden. SEC staff guidance in 2025 eased what counts as reasonable verification under 506(c).

Not while you are relying on Rule 506(b) — general solicitation or advertising is exactly what 506(b) prohibits, and a public post about a live raise can blow the exemption. If you want to talk publicly, the offering has to be structured under 506(c) from the start, which means every purchaser accredited and verified rather than merely reasonably believed to be. This is a common failure mode and it appears in none of the process guides surveyed.

Form D is due within 15 days after the first sale of securities in the offering. The clock runs from the first sale, not from the first conversation and not from the closing.

Searches often run 24 months or longer, and roughly one third of searchers never acquire a company at all. That base rate is why buy-side origination is a funded function rather than a project: sell-side origination cost is embedded in a success fee, while buy-side origination is fixed cash burn against an uncertain outcome.

Exclusivity should cover confirmatory diligence and the financing commitment and stop there, because the period is not administrative — it is the entire window in which the buyer holds leverage. Leverage inverts the moment exclusivity attaches: before it, competitive tension favors the seller; after it, the seller has no alternative and the buyer holds retrade power. That inversion is why the binding half of an LOI is narrow — exclusivity, confidentiality, expenses, governing law — and why everything the buyer wants on risk allocation belongs in the LOI itself, not in the first draft of the agreement.

Each block below opens a cornerstone page in one of this hub's pillars: the passage, the takeaways, and — where a figure is published — the row-by-row provenance and confidence tier behind it.
A buy-side process runs nine stages: thesis, origination, screening, indication of interest, letter of intent and exclusivity, diligence launch, investment committee approval, financing, and integration planning. It is not the mirror image of a sell-side process. Origination is a permanent function rather than a project, the approval gate has no sell-side analogue at all, and integration planning starts before signing — three structural differences that reorder the whole calendar.
| Asymmetry | Stage where it bites | Basis | Evidence |
|---|---|---|---|
| The buy-box has no sell-side analogue — the buyer runs a portfolio of processes with a base rate | Thesis | Search-fund research: searches frequently exceed two years and roughly a third of searchers never acquire | PrimaryT2-11 |
| Who pays for the funnel: sell-side origination cost is embedded in a success fee, buy-side origination is fixed cash burn against an uncertain outcome | Origination | Same research; the reason dedicated search capital exists as a separate raise | PrimaryT2-11 |
| Leverage inverts at exclusivity — competitive tension before, retrade power after | Letter of intent | Practitioner guidance on drafting a competitive letter of intent | PrimaryT3-29 |
| Parallel versus serial: the seller runs one gated process, the buyer runs eight to fourteen workstreams on one clock | Diligence launch | Structural synthesis from the diligence workstream map | Synthesis |
| The integration-of-findings problem — a late finding in one workstream invalidates a model built off another | Diligence launch | Structural | Synthesis |
| The approval gate has no sell-side analogue at all | Investment committee | Structural | Synthesis |
| Financing conditionality is scored against the bid, and the only mitigation is evidence in the letter of intent | Financing | Practitioner guidance, element two of a competitive letter of intent | PrimaryT3-29 |
| Integration planning starts pre-signing and has no sell-side counterpart | Integration planning | Structural | Synthesis |
Method The asymmetry table is ordered by the stage at which each difference first has an operational consequence, not by importance, and every row states whether it rests on a fetched source or on structural synthesis from the node graph.
In US private M&A, a letter of intent, a term sheet and a memorandum of understanding are functionally near-identical — the label is drafting convention, not legal effect. What matters is which clauses bind. Binding provisions are typically confined to exclusivity, confidentiality, expenses and governing law; price and structure are non-binding. Signing it inverts the leverage, which is why every economic term you want must be written down before you sign.
Thesis through integration planning. Read the gaps as well as the steps: there is no sell-side analogue to stage 1 or stage 7, and stage 9 begins before signing rather than after closing.

No timings are published on these steps. Buy-side stage durations are not separately sourced, and the search-fund base rate that does have a source — searches often 24 months or longer, roughly one third of searchers never acquiring — is a funnel statistic, not a stage clock.
