A Change-of-Control Clause the Share Deal Was Supposed to Avoid

The situation

The buyer, a regional HVAC and refrigeration services platform, is acquiring a family-owned refrigeration and light-commercial HVAC maintenance business in southwestern Ontario — $7.1 million revenue, roughly $1.2 million EBITDA, servicing supermarket refrigeration cases and commercial rooftop units. Deal counsel structured the transaction as a share purchase for a specific reason: the target's commercial lease barred any assignment, sublease or transfer of the lease without the landlord's prior written consent, and its largest customer contract, with a regional grocery chain, barred assignment on similar terms. A share purchase assigns nothing — the corporation that signed both contracts is the same corporation that holds them the day after closing — so neither anti-assignment clause is engaged, and counsel expected to close without asking either counterparty for anything.

The problem

That reasoning is correct, and it is exactly backward for what actually slowed the closing. A later-stage contract review, prompted by the buyer's lender rather than the deal team's own checklist, found that three of the target's material contracts do not use assignment language at all — they use change-of-control language, which is drafted to catch precisely the transaction a share purchase is. The grocery chain's service agreement required prior written notice and consent to any change in the ownership or voting control of the contractor. The target's $1.1 million term loan and $450,000 operating line, both with the target's principal bank, accelerated on a change of control of the borrower without separately restricting assignment at all. The fleet lease covering eleven service vans gave the equipment lessor a termination right on any change in beneficial ownership of more than half the lessee's shares.

The numbers

The exposure sat in three numbers, not a diffuse risk. The grocery contract represented $1.85 million of the target's $7.1 million revenue — about 26%. The bank facilities totalled $1.55 million outstanding, repayable on demand if the change-of-control clause was triggered and not waived. The fleet lease covered $340,000 of remaining payments on vans the business cannot operate without. None of the three would have surfaced from a search built to find assignment restrictions, because none of them restrict assignment.

The rule that decided it

No statute governs whether a share purchase triggers a change-of-control clause. That question is answered entirely by how the individual clause defines its own trigger, and the drafting distinction is the whole of the mechanic. An anti-assignment clause is engaged only when the contracting party itself changes, which a share sale does not do. A change-of-control clause is engaged by the opposite event — a change in who owns or controls that same corporation — and is drafted for the specific purpose of giving a landlord, lender or customer a say when a business is sold in a form that would not otherwise require their consent. A deal team that searches a target's contracts for the word "assign" and stops there will miss every one of these by design, not by accident.

The outcome

All three were resolved before the outside date, though not without cost to the schedule. The grocery chain's consent came back in nine days once its legal department reviewed the buyer's covenant strength; it wanted the buyer's parent to guarantee the contract's minimum-volume commitment for eighteen months, which the buyer agreed to. The bank issued a waiver conditional on the buyer's guarantee replacing the seller's personal guarantee at closing, which the facility already contemplated on a change of control. The equipment lessor was the hardest: it initially refused consent outright and had to be offered a replacement guarantee and a small facility fee before it agreed, twelve days after the deal team first raised it — the closing date moved by exactly that many days.

What it would have cost otherwise

Had the clauses surfaced on the closing table instead of three weeks earlier, the likely path was to close anyway and manage the fallout, which put real money at risk on all three fronts at once. The grocery chain could have terminated on 30 days' notice once it discovered an undisclosed change of control, taking $1.85 million of revenue with it. The bank facilities were repayable on demand, and a $1.55 million call would have forced a bridge refinancing at a materially worse rate mid-integration. The lessor could have repossessed the vans the business runs its service calls on. None of this is a purchase-price adjustment; each is a going-concern risk a post-closing warranty claim does not fix.

The tell

The tell was in the drafting, not the deal. Every contract the initial search caught used the word "assign" somewhere in its restriction clause; the three it missed did not use that word at all. A keyword search for "assign" or "assignment" — the search every deal team runs first, because it is the obvious thing a share structure is chosen to avoid — will systematically miss change-of-control language, because the two clause types are drafted to catch opposite events and use different vocabulary to do it. The fix is not a better keyword; it is reading each material contract's own consent and notice provisions, not just its assignment clause.

Takeaways

• • A share purchase avoids triggering an anti-assignment clause because no assignment occurs; it does nothing to a change-of-control clause, which is drafted for exactly that transaction.
• • Searching contracts for "assign" will not find change-of-control language — read each material contract's own consent and notice provisions, not only its assignment clause.
• • The structure chosen specifically to avoid asking for consents is what creates the need for them, on any contract that defines its trigger by ownership rather than by the identity of the contracting party.
• • In an asset purchase the analysis inverts: the change-of-control clause is not triggered because the counterparty's contract is novated to a new entity rather than the shareholders changing; the anti-assignment clause governs instead, and the consent list is a different list.
