For SBA lenders
Short answer
A minority equity stake can create affiliation if it confers negative control, such as the ability to block significant business decisions, or when combined with other factors indicating control.
Affiliation rules are based on the power to control, not just the exercise of control. Even a minority stake can be affiliating if it includes rights that allow the minority owner to prevent a quorum or block significant actions like mergers, asset sales, or executive hiring/firing, thereby exercising negative control.
A principal owns 30% of Company A and a separate 20% of Company B. While 20% is a minority, if Company B's operating agreement grants this principal veto power over major operational decisions, it could establish negative control, triggering affiliation between Company A and Company B.
Insider move
Lenders must scrutinize operating agreements, bylaws, and shareholder agreements for any supermajority voting requirements or special rights granted to minority owners that could constitute negative control, which is a common trigger for affiliation.
