CIM (Confidential Information Memorandum)

The CIM (Confidential Information Memorandum) is the central document of the M&A sale process: the detailed package the seller prepares for qualified buyers once they have signed an NDA. It goes beyond describing the business: a well‑prepared CIM presents normalized EBITDA, the investment thesis, risk profile, and transaction structure so a serious buyer can build its internal investment case without weeks of preliminary calls. In Mexican SME M&A, CIM quality is a direct signal of how prepared the seller is — and how the rest of the process will go.

What does a CIM contain?

• Executive summary

  1–2 pages. Overview of the business, sector, geography, and why the opportunity is attractive. Written for a buyer who has 5 minutes before deciding whether to keep reading.

• Business description

  History, products or services, operating model, competitive position, key suppliers and customers. Concentration risk is either addressed here proactively or discovered later in diligence.

• Team and organizational structure

  Key people, roles, owner‑dependency profile. A CIM that honestly presents 85% owner dependency — with a transition plan — is more credible than one that omits it.

• Financial performance (3–5 years)

  Historical P&L, bridge from reported to normalized EBITDA, margin trends, capex, working capital. This is where most buyers spend the most time.

• Normalized EBITDA and adjustment bridge

  The most important section for valuation. It shows reported EBITDA, each adjustment with justification and supporting documentation, and the normalized EBITDA that will serve as the valuation base. A buyer that cannot reconcile this bridge will not submit a serious offer. For more on normalization in this context, see Normalized EBITDA.

• Proposed transaction structure

  Asset purchase vs. share purchase, indicative EV range, proposed consideration structure (cash at closing, seller note, contingent tranche), exclusivity expectations.

• Closing conditions, process, and appendices

  Timeline, diligence expectations, data room access, contact for questions, and appendices with supporting financials, customer list (anonymized if needed), and key assets and contracts (redacted).

How is the CIM used in a transaction?

The CIM is prepared after the seller and advisor have completed the normalized EBITDA bridge and defined the transaction structure. It is sent only once the buyer has signed the NDA — never before. In a competitive process (multiple buyers) the CIM is sent to all qualified buyers at once together with a process letter that sets the deadline for indicative offers. In a bilateral process (single buyer) it serves as the anchor document for LOI negotiation.

What the buyer does with the CIM: The buyer team reads the executive summary first. If it passes the filter, the financial section goes to the analysis team for an independent build of normalized EBITDA. The buyer looks for three things: that EBITDA holds up, that risks are disclosed and manageable, and that the structure makes sense at their return hurdle. A CIM that addresses concentration, dependency, and normalization proactively compresses the buyer’s diligence timeline and reduces the chance of a post‑LOI repricing.

Illustrative example (anonymized, sector: industrial services distribution, Mexico 2024): A capital equipment distributor prepared a CIM for a bilateral sale process. The financial section showed the following normalization bridge:

Bridge: reported → adjustments → normalized

Process metrics in this example

The CIM included a customer concentration table with the top 5 at 48% of revenue — moderate, documented, with 3‑year supply contracts for two of the five. The CIM compressed the process because the buyer did not have to do reconciliation work on its own.

A CIM that anticipates the buyer’s questions does not only speed the process — it reduces the risk of post‑LOI repricing because there are no surprises in diligence. For the full process, see stages of the M&A process and what comes next in due diligence.

How does the CIM differ from the teaser and the LOI?

The progression in three documents:

Each document has a different role. Skipping the teaser is common in bilateral processes. Skipping the CIM is a mistake in any process — going straight to LOI without a CIM means the buyer builds its investment case with incomplete information, which leads to a repricing in diligence.

What makes a CIM bad?

• Unnormalized EBITDA or no documented bridge

  The buyer cannot verify the number. They either walk or build their own normalization — which will be more conservative than the seller’s.

• Customer concentration omitted or downplayed

  If the top 3 customers are 65% of revenue and that is not in the CIM, the buyer finds out in diligence and reprices. Every risk the buyer discovers that was not disclosed becomes a negotiating lever.

• Owner dependency with no transition plan

  Saying “the founder will support the transition” without a concrete plan, timeline, and incentive structure does not reassure — it signals the seller has not thought through what the buyer is really buying.

• Unsupported projections

  Forward numbers with no clear basis — “revenue will grow 20% next year” with no pipeline, no contracts, no historical growth to back it — destroy credibility of the historical numbers too. If the projections are not reliable, the buyer discounts everything.

What do buyers and sellers ask about the CIM?

When is the CIM prepared in the sale process?

After the seller and advisor complete the normalized EBITDA bridge and define the transaction structure, once the teaser has been sent and NDAs signed by qualified buyers. In a bilateral process it can be prepared in parallel with the NDA. It must never be sent before normalization work is finished: a CIM built on reported EBITDA will produce an LOI that gets repriced in diligence.

Is the CIM the same as the teaser?

No. The teaser is 1–2 pages, anonymous, and sent before the NDA to test interest. The CIM is the full document — 10–30 pages depending on business complexity — and is sent only after the NDA is signed. The teaser gets the buyer to the table; the CIM gets the buyer to submit an offer.

How detailed should normalized EBITDA be in the CIM?

Detailed enough that a buyer analyst can verify every adjustment without a follow‑up call. Each line of the normalization bridge should include: the adjustment amount, the justification, and a reference to supporting documentation in the data room. Adjustments without documentation will be excluded by the buyer — and at the same multiple, every peso excluded from normalized EBITDA reduces EV by the multiple. At 4.5×, an unsupported adjustment of 200,000 MXN costs 900,000 MXN in enterprise value.

Is a CIM always prepared in Mexican SME transactions?

In bilateral processes (single buyer) the full CIM is sometimes replaced by a detailed information package or a structured management presentation. What does not change is the need for a documented normalized EBITDA bridge — whether in a formal CIM or another format, the buyer must see the reconciliation from reported to normalized EBITDA with support for each adjustment. Without that, there is no basis for a serious LOI.
