Delaware SB 21 and the new safe harbor for controller transactions
Delaware's 2025 amendments to Section 144 rewrote the rules for controlling stockholder transactions. The practical effect on deal structures is larger than most commentary has acknowledged.
Delaware enacted Senate Bill 21 in March 2025, amending Section 144 of the Delaware General Corporation Law to create a statutory safe harbor for transactions involving controlling stockholders. The amendments were a response to a series of decisions, most prominently the Chancery Court's analysis in In re Match Group Inc. Derivative Litigation and its aftermath, that had created uncertainty about when a controller transaction would receive business judgment review rather than entire fairness scrutiny.
The legislation moved through the General Assembly quickly. It passed both chambers in March and was signed by Governor Meyer on March 25, 2025. The text amends Section 144 in ways that matter for any deal with a controller on either side.
What the safe harbor actually says
The amended Section 144 establishes that a transaction with a controlling stockholder is entitled to business judgment review if the transaction is approved by either an independent board committee that meets defined requirements or by an informed majority of disinterested stockholders. The bill defines independence and disinterest in statutory terms, narrowing some of the case-by-case analysis that had developed in Chancery.
The previous framework, articulated in the Trados and Kahn lines of cases and most recently refined in Match Group, required both procedural protections (the so called MFW dual conditioning) to qualify for business judgment review. The new statute reduces that to an either or. Either the special committee process is in place, or the disinterested stockholder vote is in place, and not necessarily both.
What it changes for PE controllers
The clearest beneficiary is the sponsor that holds a control position in a portfolio company and wants to execute a follow on transaction without entire fairness exposure. Under the prior law, the safest path to business judgment was a dual conditioned process: an independent committee with the full panoply of MFW protections plus a majority of the minority vote. The new statute makes either path sufficient on its own, which gives the sponsor real flexibility in structuring follow ons.
The biggest practical change is timing. Building a dual conditioned MFW process is expensive and takes months. A single conditioned process, properly structured, can move on the kind of timeline a sponsor actually wants for an add on acquisition or a recapitalization.
What it does not change
Two things have not changed and the bar is sometimes muddling them.
First, the duty of loyalty has not been amended. A controller still owes the same fiduciary duties to minority stockholders. The safe harbor governs the standard of review for the transaction, not whether the controller has breached its duties.
Second, the statute does not foreclose claims based on disclosure failures or process defects. A controller who shoehorns a transaction into the statutory safe harbor without actually running an arms length process is still exposed. Chancery will read the safe harbor strictly.
What deal counsel should do now
For sponsor controllers, the structural choice between MFW and single conditioning is now a real strategic decision rather than a checklist. The decision should be made early and documented well. If the deal is going to rely on disinterested stockholder approval, the proxy and consent solicitation process needs to be designed with the statute's definitions of disinterest in mind.
For boards facing a controller transaction, the question of which path to take should be on the table at the first board meeting where the transaction is discussed. Choosing the committee path versus the stockholder vote path changes the deal calendar by months and changes the cost of the transaction by hundreds of thousands of dollars on a middle market deal.
For all corporate counsel, the case law that built up over the last fifteen years on controller transactions is now subject to a statutory overlay. The treatises will be revised. The CLE materials are being rewritten. Reading the bill itself, not just the summaries, is worth the hour.
The amendments are the most significant statutory change to Delaware corporate fiduciary doctrine in a decade. The full implications will not be clear until Chancery has interpreted the new statute in a meaningful number of cases. But the practical effect on deal structuring is already visible in matters that closed in the months after enactment.
