HOHW
Provisions

WHAT MUST BE DONE

TO OBTAIN REGULATORY CLEARANCES

SUMMARY


A hell-or-high-water provision is a pre-closing covenant relating to regulatory approvals. It most frequently arises in the antitrust context, but may come up where other regulatory regimes—like foreign investments in domestic businesses (e.g., CFIUS)—are at issue.




EFFORTS STANDARD


In its foundational form, a HOHW clause requires one or more parties, usually on the buy-side, to take any and all actions necessary to obtain the designated regulatory approvals. It would include, for example, selling assets, exiting investments, and defending against government litigation challenging a transaction, at any cost.




IN PRACTICE


HOHW clauses are most often sought by sellers running competitive auctions, and prospective buyers may agree to them, with or without modifications, depending on their respective risk tolerance, institutional policies, and broader investment portfolios.


For example, buyers may agree to accept the clause in principle, but insist on materiality qualifiers (to prevent wholesale portfolio losses) and specificity about which acquisition vehicles the clause applies to (where, in particular, partnerships with co-investors exist).
