What Red Flags Should You Watch for in M&A Advisors?

Warning signs when interviewing M&A advisors — from valuation promises to fee opacity to lack of relevant closed deals.

By John Norton · March 22, 2026

Some warning signs are subtle. Others are neon. Watch for both.

Valuation red flags

  • Aggressive valuation promises with no comps to back them up
  • Refusal to discuss a realistic range on the low end
  • Claims that they've 'never had a deal come in below LOI'

Fee red flags

  • Vague or shifting explanations of the fee structure
  • No cap on out-of-pocket expenses
  • Long tail periods (24+ months) after engagement termination
  • Fee structures that reward closing any deal, not the right deal

Process red flags

  • No defined process, or a process that varies wildly by engagement
  • Refusal to name buyers they'd approach
  • Small buyer universes (under 20 for most deals)
  • Pressure to sign the engagement letter this week

Team red flags

  • The person selling the engagement won't be the one running the deal
  • No named day-to-day contact
  • Too many active engagements for the size of the team
  • No verifiable closed transactions in your size range in the last two years

The gut check

If you leave the first meeting feeling more confused than clear, that's a signal. A good advisor makes complex things simple. If they can't, they probably don't understand it themselves.
