Operating Agreement
The governing document for a limited liability company (LLC) defining member rights, ownership percentages, management authority, distribution policies, transfer restrictions, and exit provisions. In M&A, operating agreements are a primary diligence document for LLC acquisitions — revealing ownership structure, change-of-control restrictions, member consent requirements, and preemptive rights. Missing or informal operating agreements are a red flag that can delay deals.
Full Definition
An operating agreement is the foundational governing document for a Limited Liability Company (LLC) — the legal contract among LLC members (owners) that defines ownership percentages, management structure, economic rights, voting rights, decision-making authority, and the mechanics for distributing profits, handling member exits, and resolving disputes. It is the LLC equivalent of corporate bylaws and a shareholders' agreement combined, and it governs how the business is operated and how member interests are transferred or sold.
For M&A purposes, the operating agreement is among the first documents a buyer reviews in due diligence for any LLC acquisition — whether a stock-equivalent purchase of LLC membership interests or an asset acquisition from an LLC entity. The operating agreement reveals: who controls the LLC (manager-managed or member-managed?), what decisions require member consent and at what thresholds (simple majority, supermajority, unanimous?), whether there are any drag-along or tag-along rights, what restrictions exist on transferring membership interests (right of first refusal, restrictions on non-qualifying transfers), and what happens if a member wants to exit, dies, or becomes incapacitated.
In SMB acquisitions, operating agreements are frequently poorly drafted or outdated. Many small LLCs were formed with a standard form operating agreement that doesn't adequately address the business's actual ownership and governance needs. Key gaps include: missing buy-sell provisions (no clear mechanism for forcing or accommodating a member buyout), outdated ownership percentages (the agreement reflects original ownership but equity has been informally transferred or promised without updating the agreement), missing drag-along or tag-along provisions, and ambiguous manager authority (the agreement doesn't clearly specify what decisions the manager can make unilaterally vs. what requires member approval).
For acquisitions of LLC interests, the operating agreement's transfer restrictions are particularly important. Most operating agreements require some form of member consent (unanimous or majority) for any transfer of membership interests to a non-member. A buyer who fails to obtain the required consents for the transfer of membership interests may find that the transfer is void under the operating agreement — creating title defects that are expensive and time-consuming to correct.
Post-acquisition, if the acquired LLC continues as an operating entity (in a membership interest purchase), the new owner will want to amend or replace the operating agreement to reflect: new ownership, updated management provisions, appropriate information rights and observer rights for any rollover holders, and governance rights that match the new capital structure.
Seller vs. Buyer Perspective
Review and update your operating agreement before going to market. Common issues to address pre-sale: update ownership percentages to reflect actual current ownership (if equity has been informally transferred or promised), add or fix drag-along provisions (so you can compel minority member participation in a sale), clarify manager authority (to avoid requiring member votes for operational decisions during the deal process), and update any outdated buy-sell mechanisms that might create complications.
For LLC interest sales, the operating agreement's transfer restrictions will require member consent at the thresholds specified. If the agreement requires unanimous consent and you have a minority member who is opposed to the sale, that consent requirement gives them significant blocking power. Address this before going to market — either through a pre-sale buyout, a buy-sell mechanism, or renegotiating the agreement with minority member cooperation.
If you're a minority interest seller, understand your rights under the operating agreement precisely. What rights do you have to compel a sale (forced buyout provisions)? What tag-along rights protect you in a majority sale? What economic rights (distributions, exit proceeds) apply specifically to your class of membership interest? These rights are in the operating agreement — read it carefully before negotiating.
For LLC membership interest acquisitions, the operating agreement review is fundamental — it's the document that defines what you're buying. Review it carefully for: (1) transfer restrictions and required consents; (2) any outstanding economic rights of existing members beyond their stated percentage (preferred returns, catch-up provisions, carried interest); (3) management authority provisions that limit your ability to operate the business post-close; and (4) any existing rights of first refusal, preemptive rights, or co-sale rights that might be triggered by the acquisition.
For post-acquisition governance, prepare a new or amended operating agreement that reflects your ownership structure, governance rights, and investment protection provisions. A standard post-acquisition LLC operating agreement for a PE-backed company should include: manager authority provisions (clear authority for day-to-day operations, defined threshold for member approval requirements), drag-along provisions (allowing you to compel minority member participation in a future exit), information rights for any rollover equity holders, and anti-dilution protections for rollover members.
Purchase agreement representations should include specific representations about the operating agreement: that the version provided is current and complete, that there are no side letters, amendments, or oral modifications, that the ownership percentages are accurate, and that all required consents for the transaction have been obtained. These representations protect you against operating agreement surprises post-close.
Real-World Example
A buyer conducts diligence on an LLC with three members: the founder (60%), his brother (25%), and an early employee (15%). The operating agreement, drafted 8 years ago, requires unanimous member consent for any sale or transfer of membership interests. The early employee, unhappy with the proposed valuation of his 15% stake, refuses consent — effectively blocking the sale. The buyer must either: (1) negotiate directly with the employee to increase his consideration, (2) restructure the deal as an asset purchase (which doesn't require membership interest transfer consent), or (3) work with the founder to find a legal mechanism to override the unanimous consent requirement. The buyer and seller choose an asset purchase structure, avoiding the transfer consent requirement — but the buyer loses the step-up tax benefit of a membership interest purchase. A drag-along provision in the original operating agreement would have prevented this entirely.
Why It Matters & Common Pitfalls
- !Outdated ownership percentages. Operating agreements that don't reflect actual current ownership create title chain issues that must be resolved before closing. Verify that the operating agreement matches current ownership records and update before going to market.
- !Unanimous consent transfer restrictions. Small LLC operating agreements often require unanimous member consent for transfers — giving any member blocking power over a sale. Identify this requirement early and plan for it.
- !Informal equity promises. Founders who promised equity to employees or advisors verbally, through emails, or through informal agreements may have created enforceable ownership rights not reflected in the operating agreement. Audit all equity commitments before selling.
- !Manager authority ambiguity. Operating agreements that don't clearly define manager authority vs. member vote requirements can create operational paralysis during the pre-close period if members disagree about what management can do without their approval.
