Does the Delaware appraisal statute exclude the buyer’s synergies?
Yes, by its own words. Section 262(h) of the Delaware General Corporation Law provides that “Through such proceeding the Court shall determine the fair value of the shares exclusive of any element of value arising from the accomplishment or expectation of the merger, consolidation, conversion, transfer, domestication or continuance, together with interest, if any, to be paid upon the amount determined to be the fair value,” and that “[i]n determining such fair value, the Court shall take into account all relevant factors.” Nothing in the section defines fair value itself; the content is judge-made, and the exclusion is the only substantive instruction the legislature gave.
What the exclusion does is settled law. In Verition Partners Master Fund Ltd. v. Aruba Networks, Inc., 210 A.3d 128 (Del. 2019), the Delaware Supreme Court described the task, under Cavalier Oil Corp. v. Harnett, 564 A.2d 1137 (Del. 1989), as valuing “what has been taken from the shareholder: ‘viz. his proportionate interest in a going concern,’” so that the company is valued “as an operating entity . . . but without regard to post-merger events or other possible business combinations.” The consequence it drew, in words taken from Union Illinois 1995 Investment Limited Partnership v. Union Financial Group, Ltd., 847 A.2d 340 (Del. Ch. 2004), is that the court must “exclude from any appraisal award the amount of any value that the selling company’s shareholders would receive because a buyer intends to operate the subject company, not as a stand-alone going concern, but as a part of a larger enterprise, from which synergistic gains can be extracted.”
Whether a legislature excluded transaction-created value is a matter of reading the statute, the layer described in Pueblo Bancorporation v. Lindoe, Inc., 63 P.3d 353 (Colo. 2003): “the meaning of ‘fair value’ is a question of law, not a question of fact to be opined on by appraisers and decided by the trial court.” How much a record supports subtracting is the other layer, and it is a finding of fact.
What has “the accomplishment or expectation of the merger” been held to mean?
It excludes the value the transaction itself creates, and it reaches further than the transaction before the court. In Verition Partners Master Fund Ltd. v. Aruba Networks, Inc., 210 A.3d 128 (Del. 2019), the Delaware Supreme Court said the command in 8 Del. C. §262(h) has been interpreted “as ruling out consideration of not just the gains that the particular merger will produce, but also the gains that might be obtained from any other merger,” so that fair value “is more properly described as the value of the company to the stockholder as a going concern, rather than its value to a third party as an acquisition” — a formulation quoted from M.P.M. Enterprises, Inc. v. Gilbert, 731 A.2d 790, 795 (Del. 1999). The dissenter is paid for the company as it stood, not as a component of another enterprise.
The exclusion is narrower than “no merger value” suggests: it is aimed at value arising from the transaction, not at everything near it. Delaware does not backdate; the Aruba court noted that §262 requires fair value to be assessed as of “the effective date of the merger,” so events between signing and closing can matter. In In re Appraisal of Regal Entertainment Group, Cons. C.A. No. 2018-0266-JTL (Del. Ch. 13 May 2021), the Court of Chancery subtracted from the deal price the portion of the buyer’s anticipated synergies that the price had allocated to the seller’s stockholders, then added value for an increase after signing and before closing, when the Tax Cuts and Jobs Act reduced the corporate tax rate. Those answer two different questions.
Aruba also policed a second deduction: the Court of Chancery had declined to use its own deal-price-less-synergies figure partly because that figure “continues to incorporate an element of value resulting from the merger” in the form of “reduced agency costs.” The Supreme Court held that reasoning an abuse of discretion on that record, observing that the buyer’s synergies case “likely already priced any agency cost reductions it may have expected.”
Is deal price less synergies the required method in a Delaware appraisal?
No. It is the indicator Delaware courts have most often found reliable in arm’s-length sales, but no decision makes it compulsory. In DFC Global Corp. v. Muirfield Value Partners, L.P., 172 A.3d 346 (Del. 2017), the respondent asked the Delaware Supreme Court to establish “by judicial gloss, a presumption” that in certain arm’s-length mergers the deal price is the best estimate of fair value, and the court answered: “We decline to engage in that act of creation, which in our view has no basis in the statutory text.” It reversed and remanded on several grounds, one of which was that the Court of Chancery’s decision to give one-third weight each to the deal price, a discounted cash flow valuation and a comparable companies valuation “was not explained.”
Dell, Inc. v. Magnetar Global Event Driven Master Fund Ltd., 177 A.3d 1 (Del. 14 December 2017), came at the problem from the other side. The Delaware Supreme Court reversed in part “because the reasoning behind the trial court’s decision to give no weight to any market-based measure of fair value runs counter to its own factual findings,” and agreed with the company’s “core premise that, on this particular record, the trial court erred in not assigning any mathematical weight to the deal price.” The often-repeated line that a Delaware court need assign no mathematical weight to the deal price is not that holding: in Dell it appears in the court’s summary of the petitioners’ argument, which was that the company was itself urging an “inflexible bright-line rule” by suggesting the trial court was required to “assign some mathematical weight to the deal price.” The court also marked the limits of what it had decided: “we are not saying that the market is always the best indicator of value, or that it should always be granted some weight,” and on remand it declined “to dictate” the deal price as the result, giving the Vice Chancellor “the discretion on remand to enter judgment at the deal price if he so chooses.” Aruba supplied a later instance, directing entry of “a final judgment for the petitioners awarding them $19.10 per share, which reflects the deal price minus the portion of synergies left with the seller as estimated by the respondent in this case, Aruba,” measured against the $24.67 per share the Aruba board had accepted. That figure was the respondent’s own litigation estimate in that case, adopted by that court on that record; it is not a benchmark, and this Institute publishes no figure of its own.
What came after shows range rather than a trend. In Brigade Leveraged Capital Structures Fund Ltd. v. Stillwater Mining Co., 240 A.3d 3 (Del. 12 October 2020), the Delaware Supreme Court affirmed, holding that the Court of Chancery “did not abuse its discretion when it deferred to the deal price as a reliable indicator of fair value without an upward adjustment”; the petitioners in that case sought an increase for a rise in the palladium price between signing and closing and, as the party arguing for an upward adjustment, did not carry their burden on that record. No form of the word synergies appears in the opinion, so it is not a deal-price-less-synergies decision. In In re Appraisal of Regal Entertainment Group the Court of Chancery said the Delaware Supreme Court had “elevated the deal-price-less-synergies metric to its current position as first among equals,” which is not a presumption.
The burden is why outcomes diverge, and it sits on both sides. In re Appraisal of Regal Entertainment Group, Cons. C.A. No. 2018-0266-JTL (Del. Ch. 13 May 2021), restates it: “both sides have the burden of proving their respective valuation positions by a preponderance of [the] evidence,” quoting Fir Tree Value Master Fund, LP v. Jarden Corp., 236 A.3d 313, 322 (Del. 2020), and adds that “[e]ach party also bears the burden of proving the constituent elements of its valuation position . . . , including the propriety of a particular method, modification, discount, or premium,” a formulation the Court of Chancery took from its own post-trial opinion in the Stillwater appraisal. A respondent seeking a synergies deduction must prove the synergies and the share of them the price handed the seller.
When does a court use the unaffected market price instead of the deal price?
Sparingly, and not as the sole measure merely because the market was efficient. In Verition Partners Master Fund Ltd. v. Aruba Networks, Inc., 210 A.3d 128 (Del. 2019), the Court of Chancery had set fair value at $17.13 per share, the thirty-day average price at which the shares traded before news of the transaction leaked; the Supreme Court reversed, holding that it “abused its discretion in using Aruba’s ‘unaffected market price’ because it did so on the inapt theory that it needed to make an additional deduction from the deal price for unspecified ‘reduced agency costs.’”
The opinion is equally clear that trading prices are evidence. It says that to the extent the Court of Chancery read DFC and Dell as reaffirming “that the price a stock trades at in an efficient market is an important indicator of its economic value that should be given weight, it was correct,” while adding that those decisions “did not imply that the market price of a stock was necessarily the best estimate of the stock’s so-called fundamental value at any particular time.” What sank the measure was evidentiary distance: the unaffected price was “a measurement from three to four months prior to the valuation date,” and the buyer held material nonpublic information not in the public price.
A different record can produce the opposite ruling for reasons of proof rather than principle. In In re Appraisal of Regal Entertainment Group, Cons. C.A. No. 2018-0266-JTL (Del. Ch. 13 May 2021), the Court of Chancery declined to rely on the trading price while stating that the decision “has not held that the trading market for Regal’s common stock was inefficient, nor that the trading price of Regal’s common stock was wholly unreliable”; what it held was that the respondent, Cineworld, “failed to carry its burden to show that the market for Regal’s common stock was sufficiently efficient to be used as an indicator of fair value when another market-based indicator is available.” Which indicator a particular record will carry is contested valuation practice rather than statutory construction, and how valuation methods are built and defended is the subject of the Business Acquisitions Institute; what belongs here is what the statute excludes and who must prove its size.
Do other states’ appraisal statutes treat synergies the way Delaware does?
No, and the differences are on the face of the statutes. California does not use the fair value label in its dissenters’ rights provision at all. California Corporations Code §1300(a) requires the corporation to purchase dissenting shares “at their fair market value,” determined “as of the day of, and immediately prior to, the first announcement of the terms of the proposed reorganization or short-form merger, excluding any appreciation or depreciation in consequence of the proposed reorganization or short-form merger, as adjusted for any stock split, reverse stock split, or share dividend that becomes effective thereafter.” California moves the clock back to the day before the announcement and excludes movement caused by the deal; Delaware leaves the clock at the effective date and subtracts. That is California’s rule and Delaware’s, respectively, and neither travels.
New York points the other way on the same question. New York Business Corporation Law §623(h)(4) fixes value “as of the close of business on the day prior to the shareholders’ authorization date” and then directs that “[i]n fixing the fair value of the shares, the court shall consider the nature of the transaction giving rise to the shareholder’s right to receive payment for shares and its effects on the corporation and its shareholders, the concepts and methods then customary in the relevant securities and financial markets for determining fair value of shares of a corporation engaging in a similar transaction under comparable circumstances and all other relevant factors.” A statute instructing the court to consider the transaction and its effects does not read transaction-created value out of the answer. That is New York’s rule.
A third pattern appears in states enacting the Model Business Corporation Act’s appraisal definition, which solves the problem by timing and says nothing about synergies. Virginia defines fair value as the value of the shares determined “[i]mmediately before the effectiveness of the corporate action to which the shareholder objects,” “[u]sing customary and current valuation concepts and techniques generally employed for similar businesses in the context of the transaction requiring appraisal,” and “[w]ithout discounting for lack of marketability or minority status except, if appropriate, for amendments to the articles of incorporation pursuant to subdivision A 5 of § 13.1-730” (Va. Code §13.1-729). That exclusion operates at the shareholder level and pushes the number up; Delaware’s operates at the transaction level and pushes it down, which is why fair value is not reliably the higher number — see What is the difference between fair value and fair market value?, and why the date is asked separately, at Who decides the valuation date? Each authority named here was read in a primary source on 15 September 2026, and states one jurisdiction’s rule.
