Key Takeaways

Transaction-based compensation generally requires FINRA broker-dealer registration (SEC Paul Anka Letter, January 2010)

Tail fees beyond 12-18 months capture transactions the advisor did not directly source

Scope language must define "Transaction" tightly to avoid claims on unrelated deals

Success fee agreements are the standard form for M&A advisors but sit at the boundary of securities-broker registration. The SEC has consistently held that "transaction-based compensation" — payment contingent on a securities transaction closing — generally requires broker-dealer registration under §15(a) of the Exchange Act. The Paul Anka No-Action Letter (January 2010) and the David W. Blass Letter (2014) are the leading non-action precedents. Failure to register can void the engagement and expose the advisor to disgorgement under §29(b). Standard success-fee scope (Lehman formula 5/4/3/2/1 graduated, or flat percentage) and tail period (12-18 months from termination) are negotiable but heavily-precedented. Sell-side engagements typically include exclusivity (90-180 days) and minimum fee floors. Buy-side engagements include defined "introduced parties" lists. Justee analyzes success fee agreements against FINRA registration requirements, SEC no-action precedent, and standard M&A advisor terms to flag enforceability and scope risks.

Hypothetical Case Study by Justee

Justee recently analyzed a success-fee letter with a 5% Lehman formula, 24-month tail, and scope reading "any sale of the Company or its assets to any party" for a $90M sale of a SaaS company in San Diego represented by a regional M&A advisor.

Issue Found: The advisor was not FINRA-registered. Under SEC v. Ranieri and the Paul Anka Letter, transaction-based compensation in a private M&A deal involving stock consideration likely required registration. The 24-month tail captured a strategic acquirer the founder had been talking to for two years before retention. Combined, the advisor would have collected $4.5M on a deal it played minimal role in.

Justee Recommendation: We restructured: (i) advisor partnered with a FINRA-registered broker-dealer of record (the BD took 1% override but assumed registration risk); (ii) tail capped at 12 months; (iii) tail limited to "Introduced Parties" identified on Schedule A within 10 business days of introduction; and (iv) the long-existing strategic acquirer was excluded from the engagement entirely.

Overbroad Tail and Scope

Problematic Language

"For 24 months following termination, the Company shall pay the Success Fee on any sale of the Company or its assets to any party."

Recommended Language

"For twelve (12) months following termination (the "Tail Period"), the Company shall pay the Success Fee on any Transaction with an Introduced Party. "Introduced Party" means a counterparty (i) introduced to the Company in writing by Advisor during the engagement and (ii) identified to the Company in writing on the Introductions List attached as Schedule A within ten (10) business days of introduction. The Tail Period shall not apply to (a) parties already engaged in active discussions with the Company prior to the engagement (the "Pre-Engagement Excluded Parties" listed on Schedule B), (b) Affiliates of the Company, or (c) involuntary transactions (foreclosure, bankruptcy)."

Why it matters: The amended language ties the tail to actual advisor contribution, defines Introduced Parties with documentation, and excludes pre-existing relationships.
