Distribution Lock-Up Events.
1. What is a Distribution Lock-Up Event?
A Distribution Lock-Up Event refers to circumstances under which a shareholder, investor, or company insider is restricted from selling or transferring shares of a company for a specified period. These events usually occur after:
Initial Public Offerings (IPOs)
Private Placements
Stock Incentive Plans
Mergers or Acquisitions
The main objectives are:
Stabilization of stock prices – preventing insiders from flooding the market immediately after an IPO.
Alignment of interests – ensuring key stakeholders remain invested in the long-term success of the company.
Regulatory compliance – following securities laws or contractual agreements in investment rounds.
Key Components:
Lock-up Period: The duration of restriction, often 90–180 days post-IPO.
Trigger Events: IPO, acquisition, merger, or default.
Exceptions: Transfers for estate planning, divorce settlements, or pre-approved sales.
2. Legal Context
Lock-up provisions are generally enforced under:
Securities Law: For IPOs, Rule 144 under the U.S. Securities Act governs restricted securities.
Shareholders’ Agreements: Contracts among founders and investors often have lock-up clauses.
Employment/Executive Contracts: Stock options granted to executives may have lock-up restrictions post-exercise.
Violating a lock-up can lead to:
Civil liability
Contractual penalties
Regulatory action
