A deal teaser is a first look, not a reason to start full diligence. The useful question is simple: does the business appear close enough to the firm's buy box to justify one more step? A quick, consistent screen helps the team decide what to ask, what to park, and what to pass.
The teaser may be short and leave important details open. That is fine at this stage. Separate what it actually says from what you still need to learn, and avoid treating a missing fact as if it confirms a fit.
Start with what the company does
Look for a plain description of the product or service, the customers who pay for it, and the markets the company serves. Those details are more useful than a broad industry label. A field service contractor, for example, could serve factories, homes, or both. The label may sound right while the customer mix tells a different story.
Compare the main business with the firm's stated focus. Check geography, end market, and whether the company looks like a potential platform or a possible add-on. If one of those points is unclear, write down the specific gap rather than quietly filling it in yourself.
Check the size figures and their basis
Compare revenue and EBITDA with the firm's actual range. Then check what period the figures cover and how they are described. Is EBITDA reported, estimated, or adjusted? Does the teaser say whether the figure is for a full year or a shorter period? If the basis is absent, treat the number as unconfirmed for the screen.
This matters because private-company disclosures can vary in detail and quality. CFA Institute notes that private companies range widely in the quality of their financial disclosure, and that earnings adjustments are used to address inconsistencies before forecasting. Read its overview of private-company valuation. At the teaser stage, you do not need to resolve every adjustment; you do need to know what the headline figure represents.
Separate fit issues from open questions
A company outside the firm's geography or size range may be a clear pass. A company that appears to fit but has not identified its main customers may need one follow-up. Keep those outcomes distinct. Requesting a full set of materials when a basic mandate test already fails wastes time for the buyer and the intermediary.
Look for the one unanswered point that could change the decision. It might be the share of revenue from a particular service, the period behind the earnings figure, or whether a stated market is the company's main market. If the answer would not change the screen, it does not need to hold the deal open.
Make the first decision easy to explain
A short screen note can cover four things: what the business sells, where its size appears to fall, which parts match the buy box, and what fact remains open. Finish with one of three decisions: pass, ask one focused question, or take the next step. The note should make sense to another person on the deal team without rereading the whole teaser.
A teaser rarely settles whether to buy a company. It helps a buyer decide whether there is a good reason to learn more. Keep that first decision tied to the firm's criteria, and let the next set of information answer the next set of questions.
