Executive teams preparing for a corporate exit spend months on valuation, cap table structure, and intellectual property. Vendor contracts and service agreements get reviewed last, and in M&A transactions, that sequencing can be an expensive mistake.
When a corporate exit is on the table for companies and mid-market enterprises, leadership attention naturally focuses on enterprise valuation, cap table reconciliation, and intellectual property. Ordinary vendor and customer service agreements are often the last documents reviewed during pre-deal preparation. That oversight can result in unexpected purchase price adjustments, escrow holdbacks, or last-minute renegotiations that erode seller leverage right at closing.
The contract assignment problem in Texas transactions
During due diligence, a single poorly structured service contract can introduce complications that delay or reopen a deal. Buyers discount businesses with incomplete or disorganized documentation, making a pre-deal contract audit a direct contributor to protecting transaction value.
How assignment issues arise depends on the transaction structure:
- Asset purchases: A standard anti-assignment clause is triggered because the contracts physically transfer from the selling entity to the acquiring entity. The buyer cannot step into the seller’s contractual position without securing written consent from every counterparty, a process that takes time and can produce friction with key vendors.
- Equity purchases and mergers: Whether a transaction triggers third-party consent rights depends heavily on specific contract language. When a statutory merger takes effect, all property interests vest in the surviving entity without an assignment or transfer having occurred. As a result, a standard clause prohibiting assignment “by operation of law” may be considered insufficient to require consent in a typical equity deal or merger. However, when a contract explicitly states that a merger or change-of-control event itself constitutes a default or triggers a consent requirement, that provision is generally enforceable.
Understanding the distinction between these structures before the data room is assembled gives sellers meaningful control over how counterparties respond during due diligence.
Contractual traps that surface at closing
Beyond assignment clauses, several technical issues can create problems on or after closing day:
- Notification and consent windows: Missing a post-closing notice deadline, for example a requirement to notify a vendor within 10 days of a change in ownership, can give a vendor grounds to declare a default or demand immediate repricing of their services.
- Data migration and portability: Cloud infrastructure agreements and data storage contracts must be reviewed to confirm that user access rights and license terms transfer to the acquiring entity without triggering additional fees or compliance obligations.
Identifying these issues before formal due diligence begins, rather than during it, gives sellers time to address them on their own terms. A corporate attorney familiar with M&A transactions can audit the data room, flag assignment and change-of-control provisions, and coordinate counterparty consent processes well before a buyer’s counsel identifies them first.
