A shareholders agreement is a contract among the shareholders of a corporation — typically a closely-held C-Corp or S-Corp — governing voting rights, transfer restrictions, drag-along and tag-along provisions, buyout mechanics, and dispute resolution. It supplements corporate bylaws and is required by lenders and investors before closing transactions.
While corporate bylaws govern the corporation's internal affairs (board structure, officer roles, meeting procedures), a shareholders agreement governs the relationship among shareholders themselves — and can override certain bylaw provisions among the contracting parties. Shareholders agreements are most important in closely-held companies where shareholders know each other and need to plan for ownership transitions, disputes, and exits. Core provisions: (1) Transfer restrictions — right of first refusal (ROFR): before any shareholder can sell to a third party, existing shareholders have the right to purchase at the same price. Co-sale rights (tag-along): if a majority shareholder sells, minority shareholders can sell their shares on the same terms. Drag-along rights: if a majority sells, they can compel minority shareholders to sell their shares on the same terms (prevents minority shareholders from blocking a sale). (2) Buy-sell mechanics — triggered by death, disability, divorce, termination of employment, or bankruptcy of a shareholder. Defines the valuation method (agreed formula, appraisal, or negotiation) and funding mechanism (life insurance, installment payment, third-party financing). Cross-purchase vs. redemption structure affects tax basis and corporate treasury management. (3) Voting agreements — supermajority requirements for major corporate decisions (mergers, acquisitions, new equity issuances, taking on debt above thresholds). Board composition rights for minority shareholders (information rights, observer seats, board seats at specific ownership thresholds). For financing, lenders review the shareholders agreement for consent requirements (does borrowing above a threshold require shareholder approval?), anti-dilution provisions that might affect the lender's collateral, and change-of-control triggers. Investors (VCs, private equity) always require a shareholders agreement as a condition of investment.
No. Corporate bylaws govern the corporation's internal governance — board composition, officer roles, meeting procedures, voting thresholds — and are filed with or available to the state. A shareholders agreement is a private contract among shareholders; it is not filed publicly and governs the relationship among shareholders specifically. Shareholders agreements can modify or supplement bylaw provisions in specific ways, but they do not replace bylaws.
S-Corps are not legally required to have shareholders agreements, but closely-held S-Corps with two or more shareholders strongly benefit from one. S-Corp specific issues the agreement should address: S-Corp election consent requirements (all shareholders must consent to and maintain S-Corp status); restrictions on transfers to ineligible shareholders (S-Corps cannot have more than 100 shareholders, cannot have non-US shareholders, and cannot have entity shareholders other than certain trusts and estates); tax distribution provisions to ensure shareholders receive enough cash to pay taxes on allocated income.
The SBA lender will review the shareholders agreement for consent requirements, anti-assignment provisions, and change-of-control triggers. If the agreement requires shareholder approval for borrowing above a threshold, the lender will require evidence that approval was obtained. SBA 7(a) loans require personal guarantees from all owners of 20%+ — if the shareholder agreement has relevant provisions about personal liability or guarantees, these must be reconciled with the SBA's guarantee requirements.
