PER CURIAM:
 In this statutory appraisal case, the Court of Chancery found that the fair value

of Aruba Networks, Inc., as defined by 8 Del. C. § 262, was $17.13 per share, which

was the thirty-day average market price at which its shares traded before the media

reported news of the transaction that gave rise to the appellants’ appraisal rights.1 In

its post-trial opinion, the Court of Chancery engaged in a wide-ranging discussion

of its view on the evolution of our State’s appraisal law and how certain recent

decisions have affected the relevance of market-based evidence to determining fair

value.2 For purposes of this appeal, we need not respond in full to the dicta and

instead focus on the key issue before us: whether the Court of Chancery abused its

discretion, based on this record, in arriving at Aruba’s thirty-day average unaffected

market price as the fair value of the appellants’ shares. Because the Court of

Chancery’s decision to use Aruba’s stock price instead of the deal price minus

synergies was rooted in an erroneous factual finding that lacked record support, we

answer that in the positive and reverse the Court of Chancery’s judgment. On

remand, the Court of Chancery shall enter 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.

 I.

In August 2014, Hewlett-Packard Company (“HP”), a publicly traded

company, approached Aruba, another publicly traded company, about a potential

combination. Aruba hired professionals and, in addition to negotiating with HP,

began to shop the deal. Five other logical strategic bidders were approached, but

none of them showed any interest.3 The petitioners did not argue below that private

equity bidders could compete given the synergies a combination with HP or another

strategic buyer could garner.4

After several months of negotiations between the two companies, the Aruba

board decided to accept HP’s offer of $24.67 per share. News of the deal leaked to

the press about two weeks later, causing Aruba’s stock price to jump from $18.37 to

$22.24. The next day, after the market closed, Aruba released its quarterly results,

which beat analyst expectations. Aruba’s stock price rose by 9.7% the following

day on the strength of its earnings to close at $24.81 per share, just above the deal

price.5

Id. at *10. The board believed that “private equity firms would not be competitive in their
potential valuations” given Aruba’s “volatile revenues and unpredictable cash flows and the
potential for synergies between Aruba’s business with a strategic acquirer.” Id. (internal quotation

 Not long after the deal leaked, both companies’ boards approved the

transaction, and Aruba and HP formally announced the merger at a price of $24.67

per share. The final merger agreement allowed for another passive market check.6

However, no superior bid emerged, and the deal closed on May 18, 2015.7

II.

On August 28, 2015, the appellants and petitioners below, Verition Partners

Master Fund Ltd. and Verition Multi-Strategy Master Fund Ltd. (collectively,

“Verition”), filed this appraisal proceeding in the Court of Chancery, asking the

court to appraise the “fair value” of their shares under § 262.8 The respondent was

Aruba, albeit an Aruba now 100% controlled by HP. In its pretrial and initial post-

trial briefing, Verition maintained that Aruba’s fair value was $32.57 per share,9 and

Aruba contended that its fair value was either $19.45 per share (before trial) or

$19.75 per share (after trial).10 In its post-trial answering brief, Aruba contended

that its “deal price less synergies” value was $19.10 per share. 11 Neither party

claimed that Aruba’s preannouncement stock price was the best measure of fair

value at the time of the merger.

Post-trial argument was scheduled for May 17, 2017, but the Court of

Chancery postponed the hearing “once it became clear that the Delaware Supreme

Court’s forthcoming decision in DFC [Global Corp. v. Muirfield Value Partners,

L.P.12] likely would have a significant effect on the legal landscape.” 13 After this

Court issued its opinion in DFC, the Court of Chancery allowed the parties to submit

supplemental briefing on the opinion’s implications, and the parties submitted

simultaneous briefs on September 15, 2017. Both parties continued to argue for their

preferred fair value calculation, and neither party advocated for the adoption of the

stock price, though Aruba did contend that the stock price was now “informative”

of fair value and lent support to its argument that fair value as of the time of the

merger was in the $19 to $20 per share range.14 And the parties hewed to these

positions during post-trial oral argument.

On December 14, 2017, this Court issued its opinion in Dell, Inc. v. Magnetar

Global Event Driven Master Fund Ltd,15 reversing the Court of Chancery’s appraisal

decision in that case. Six days later, the Vice Chancellor in this case—who was also

the trial judge in Dell—sent the parties a letter on his own motion. In the letter, the

Vice Chancellor requested supplemental briefing on “the market attributes of

Aruba’s stock” in part because he “learned how many errors [he] made in the Dell

matter.”16

The parties submitted simultaneous briefs in response to the Vice

Chancellor’s sua sponte request on January 26, 2018. In its brief, Aruba abandoned

deal price minus synergies as its main benchmark and argued for the first time that

its preannouncement stock price was “the single most important mark of its fair

value.”17 Accordingly, Aruba asked the Court of Chancery to award the thirty-day

unaffected market price of $17.13 per share.18 Aruba’s brief focused mainly on how

the market for its stock was efficient.

On February 15, 2018, the Court of Chancery issued its post-trial opinion

finding that the fair value under § 262 was $17.13 per share.19 In its opinion, the

Court of Chancery considered three different valuation measures: first, the

“unaffected market price” of Aruba’s stock before news of the merger leaked;

second, the deal price minus the portion of synergies left with the seller; and third,

the two expert witnesses’ valuations, which were based primarily on discounted cash

flow (“DCF”) models.20

In weighing the valuation methodologies, the Court of Chancery gave no

weight to the parties’ DCF models. The Court of Chancery also determined, based

on its own analysis, that the appropriate deal price minus synergies value was

$18.20. In reaching that conclusion, the Court of Chancery started with an estimate

of the total amount of synergies HP expected to realize. To determine how much of

those synergies Aruba’s stockholders received in the deal price, the Court of

Chancery took the midpoint of a study suggesting that “on average, sellers collect

31% of the capitalized value of synergies, with the seller’s share varying widely

from 6% to 51%.”21 This resulted in a deal price minus synergies value of $18.20

per share, $0.90 lower than Aruba’s own estimate of deal price minus synergies.

And although the Vice Chancellor was “inclined to think that Aruba’s

representatives bargained less effectively than they might have,” “indicat[ing] that

[Aruba] obtained fewer synergies than the midpoint range and imply[ing] value

north of $18.20 per share,”22 he failed to explain why his estimate of $18.20 per

share was more reliable than Aruba’s own estimate of $19.10 per share.

 However, the Vice Chancellor did not adopt his deal price minus synergies

value, in part because he believed that his “deal-price-less-synergies figure continues

to incorporate an element of value resulting from the merger” in the form of “reduced

agency costs that result from unitary (or controlling) ownership.” 23 To remedy this,

the Vice Chancellor elected to rely exclusively on the stock price because he thought

he would need to estimate and back out these theoretical “reduced agency costs”

from the deal price to arrive at a figure that reflected Aruba’s value as a going

concern. According to the Court of Chancery, using the “unaffected market price”

of Aruba’s publicly traded shares “provide[d] a direct estimate” of that endpoint,

which led him to find the sole indicator of fair value to be that “unaffected market

price” of $17.13 per share.24 Although § 262 requires the Court of Chancery to

assess Aruba’s fair value as of “the effective date of the merger,”25 the Court of

Chancery arrived at the unaffected market price by averaging the trading price of

Aruba’s stock during the thirty days before news of the merger leaked, which was

three to four months prior to closing.

Id. at *54. The Vice Chancellor also cited the potential that he may have made errors in “backing
out synergies” from the deal price as a reason for rejecting that figure. Id. at *53.

Id. at *54. After the Court of Chancery issued its post-trial opinion, Verition moved for
reargument, which the trial court denied. The court then entered a final judgment setting the fair
value of Verition’s shares at $17.13 per share, and this appeal followed.

 III.

We reverse the trial court’s fair value determination. Under Cavalier Oil

Corp. v. Hartnett, the Court of Chancery’s task in an appraisal case is “to value what

has been taken from the shareholder: ‘viz. his proportionate interest in a going

concern.’”26 That is, the court must value the company “as an operating entity . . .

but without regard to post-merger events or other possible business combinations.”27

Cavalier Oil draws this requirement from § 262’s command that the court determine

fair value “exclusive of any element of value arising from the accomplishment or

expectation of the merger or consolidation,”28 which this Court has 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.29 As a result, 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.”30 Under this

reading of § 262, the Court of Chancery 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.”31

For this reason, in cases where the Court of Chancery has used the price at which a

company is sold in a third-party transaction, it has excised a reasonable estimate of

whatever share of synergy or other value the buyer expects from changes it plans to

make to the company’s “going concern” business plan that has been included in the

purchase price as an inducement to the sale.32 No party in this proceeding argued to

us that the long-standing use of going-concern value, or its concomitant requirement

to excise synergy gains, should be revisited.

Applying the going-concern standard, we hold that the Court of Chancery

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.” It appears to us that the Court of Chancery

would have given weight to the deal price minus synergies absent its view that it also

had to deduct unspecified agency costs to adhere to Cavalier Oil’s going-concern

standard.33 As Verition points out, this aspect of the decision is not grounded in the

record. Judging by the law review articles cited by the Court of Chancery, the theory

underlying the court’s decision appears to be that the acquisition would reduce

agency costs essentially because the resulting consolidation of ownership and

control would align the interests of Aruba’s managers and its public stockholders.34

In other words, the theory goes, replacing a dispersed group of owners with a

concentrated group of owners can be expected to add value because the new owners

are more capable of making sure management isn’t shirking or diverting the

company’s profits, and that added value must be excluded under § 262 as “arising

from the accomplishment or expectation of the merger or consolidation.”35

However, unlike a private equity deal, the merger at issue in this case would not

replace Aruba’s public stockholders with a concentrated group of owners; rather, it

would swap out one set of public stockholders for another: HP’s.

Indeed, neither party presented any evidence to suggest that any part of the

deal price paid by HP, a strategic buyer, involved the potential for agency cost

reductions that were not already captured by its synergies estimate. Synergies do

33
The Court of Chancery identified the unspecified agency costs as one of “two significant sources
of uncertainty,” Aruba, 2018 WL 922139, at *53, the other being the imprecision of synergies
estimates.

not just involve the benefits when, for example, two symbiotic product lines can be

sold together. They also classically involve cost reductions that arise because, for

example, a strategic buyer believes it can produce the same or greater profits with

fewer employees36—in English terms, rendering some of the existing employees

“redundant.” Private equity firms often expect to improve performance and squeeze

costs too, including by reducing “agency costs.”37 Here, the Court of Chancery’s

belief that it had to deduct for agency costs ignores the reality that HP’s synergies

case likely already priced any agency cost reductions it may have expected. In short,

the Court of Chancery acknowledged that there were estimates of the synergies

expected by HP, and the record provides no reason to believe that those estimates

omitted any other added value HP thought it could achieve because of the

combination. For this reason, Aruba itself presented a deal price minus synergies

value of $19.10 per share as one of its suggested outcomes.

As to this issue, Aruba never argued that its deal price minus synergies case

did not fully account for all the “agency cost” reductions it expected, and the Court

of Chancery’s view that some measure of agency costs had to be accounted for finds

no basis in the record. Nor does it find any basis in the corporate finance literature;

EVIDENCE & PRACTICE 681 (2014).

11
given that all the cost reductions HP expected as a widely held, strategic buyer were

likely to be fully accounted for by its expected synergies.38 Theory here tracks the

facts, and there was no reasonable basis to infer that Aruba was cheating itself out

of extra agency cost reductions by using only the cost reductions that were

anticipated in commercial reality. However, instead of at least awarding Verition

the deal price minus HP’s estimate of its expected synergies left with the seller,

which generated a value that was corroborated by the standalone DCF models used

by Aruba’s and HP’s boards in agreeing to the transaction,39 the Court of Chancery

gave exclusive weight to the thirty-day average unaffected market price of $17.13

per share.

In addition to believing that it had to account for unspecified agency costs, the

Court of Chancery also seemed to suggest that rote reliance on market prices was

compelled based on its reading of DFC and Dell.40 Like any human perspective, the

trial judge’s broader reading of Dell and DFC is arguable, but the trial judge’s sense

that those decisions somehow compelled him to make the decision he did was not

supported by any reasonable reading of those decisions or grounded in any direct

citation to them. Among other things, the trial judge seemed to find it novel that

DFC and Dell recognized that when a public company with a deep trading market is

sold at a substantial premium to the preannouncement price, after a process in which

interested buyers all had a fair and viable opportunity to bid, the deal price is a strong

indicator of fair value, as a matter of economic reality and theory. The apparent

novelty the trial judge perceived is surprising, given the long history of giving

important weight to market-tested deal prices in the Court of Chancery and this

Court, a history that long predated the trial judge’s contrary determination in Dell.41

In this case, for instance, Aruba approached other logical strategic buyers prior to

signing the deal with HP, and none of those potential buyers were interested. Then,

after signing and the announcement of the deal, still no other buyer emerged even

though the merger agreement allowed for superior bids. It cannot be that an open

chance for buyers to bid signals a market failure simply because buyers do not

believe the asset on sale is sufficiently valuable for them to engage in a bidding

contest against each other. If that were the jurisprudential conclusion, then the

judiciary would itself infuse assets with extra value by virtue of the fact that no actual

market participants saw enough value to pay a higher price. That sort of alchemy

has no rational basis in economics.

In fact, encouraged by Weinberger v. UOP, Inc.,44 our courts have for years

applied corporate finance principles such as the capital asset pricing model to value

companies in appraisal proceedings in ways that depend on market efficiency. The

reliable application of valuation methods used in appraisal proceedings, such as DCF

and comparable companies analysis, often depends on market data and the efficiency

of the markets from which that data is derived. For example, it is difficult to come

up with a reliable beta if the subject company’s shares do not trade in an efficient

15
market,45 and the reliability of a comparable companies or transactions analysis

depends on the underlying efficiency of the markets from which the multiples used

in the analysis are derived.46

Even before this Court’s seminal opinion in Weinberger, the old Delaware

“block” method used market prices in one of its three prongs.47 In forsaking the

Delaware block method as a rigid basis to determine fair value, Weinberger did not

hold that market value was no longer relevant; in fact, Weinberger explicitly

condoned its use.48 Extending this basic point, DFC and Dell merely recognized

that a buyer in possession of material nonpublic information about the seller is in a

strong position (and is uniquely incentivized) to properly value the seller when

agreeing to buy the company at a particular deal price, and that view of value should

be given considerable weight by the Court of Chancery absent deficiencies in the

deal process.49

 Likewise, assuming an efficient market, the unaffected market price and that

price as adjusted upward by a competitive bidding process leading to a sale of the

entire company was likely to be strong evidence of fair value. By asserting that Dell

and DFC “indicate[] that Aruba’s unaffected market price is entitled to substantial

weight,”50 the Vice Chancellor seemed to suggest that this Court signaled in both

cases that trading prices should be treated as exclusive indicators of fair value.

However, Dell and DFC 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.51 Rather, they did recognize that when a market was informationally

efficient in the sense that “the market’s digestion and assessment of all publicly

available information concerning [the Company] [is] quickly impounded into the

Company’s stock price,” the market price is likely to be more informative of

fundamental value.52 In fact, Dell’s references to market efficiency focused on

informational efficiency—the idea that markets quickly reflect publicly available

here, not just the views of company stockholders, but also those of potential buyers of the entire

efficient market price invariably reflects the company’s fair value in an appraisal or

fundamental value in economic terms.53 Nonetheless, to the extent the Court of

Chancery read DFC and Dell as reaffirming the traditional Delaware view,54 which

is accepted in corporate finance, 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.55 And to the extent that the Court of Chancery also read DFC and Dell as

of arm’s length buyers of the entire company to learn more through due diligence,

involving confidential non-public information, and with the keener incentives of

someone considering taking the non-diversifiable risk of buying the entire entity, the

price that results from that process is even more likely to be indicative of so-called

fundamental value, it was correct.56

Here, the price that HP paid could be seen as reflecting a better assessment of

Aruba’s going-concern value for reasons consistent with corporate finance theory.

For starters, the unaffected market price was a measurement from three to four

months prior to the valuation date, a time period during which it is possible for new,

material information relevant to a company’s future earnings to emerge. Even more

important, HP had more incentive to study Aruba closely than ordinary traders in

small blocks of Aruba shares, and also had material, nonpublic information that, by

definition, could not have been baked into the public trading price. For example, HP

for any topping bidder to have the support of [the CEO’s] own votes is so compelling, then failure
to give the resulting price heavy weight because the trial judge believes there was mispricing
missed by all the Dell stockholders, analysts, and potential buyers abuses even the wide discretion
afforded the Court of Chancery in these difficult cases.”); DFC, 172 A.3d at 370 (“For these
reasons, corporate finance theory reflects a belief that if an asset—such as the value of a company

judgment as to value is likely to be highly informative and that, all estimators having equal access
to information, the likelihood of outguessing the market over time and building a portfolio of
stocks beating it is slight.”).

knew about Aruba’s strong quarterly earnings before the market did, and likely took

that information into account when pricing the deal. Based on the record evidence,

the Court of Chancery could easily have found that HP and Aruba’s back and forth

over price, HP’s access to nonpublic information to supplement its consideration of

the public information available to stock market buyers, and the currency of the

information that they had at the time of striking a bargain had improved the parties’

ability to estimate Aruba’s going-concern value over that of the market as a whole.57

In particular, HP had better insight into Aruba’s future prospects than the market

because it was aware that Aruba expected its quarterly results to exceed analysts’

expectations.58 When those strong quarterly results were finally reported—after the

close of the period that the Court of Chancery used to measure the “unaffected

market price”—Aruba’s stock price jumped 9.7%. Indeed, after the market learned

and Reversal at 4–6.
58
Aruba, 2018 WL 922139, at *11–13. The trial judge’s focus on the unaffected trading price
seems inspired by his view of Dell and in particular his view that its reference to that sort of pricing
as relevant to fair value was novel. See id. at *24–34. That is strange because the unaffected
trading price has often formed a foundational element of many forms of valuation used in our
courts, and was even a part of the Delaware block method. See, e.g., General Realty, 52 A.2d at
15–16. The trial judge’s decision to use the trading price as his sole basis for determining fair
value was his alone, and in no way dictated by a rational reading of Dell. Before the trial judge
fixated on this measure as his own focus, Aruba at most argued that it was informative of fair value
and one component for coming to a final estimate. Notably, nothing in Dell suggested that the
unaffected trading price should be used solely, especially when a bidder like HP had material
nonpublic information, and when the company itself had important earnings information it had not
released. The decision to give exclusive weight to the unaffected trading price on a record that did
not allow the ordinary adversarial process for testing the relevant factors was that of the trial court
alone.

20
about the strong quarter and the likelihood of a strategic deal with HP, Aruba’s stock

traded at $24.81, $0.14 away from the actual price HP paid. Of course, despite

expressing concern about the fact that no other bidder emerged to compete with HP

at the $24-plus price range, the Court of Chancery then awarded Verition $7.54 per

share less than the $24.67 deal price.

By relying exclusively on the thirty-day average market price, the Court of

Chancery not only abused its discretion by double counting agency costs but also

injected due process and fairness problems into the proceedings. As Verition argued,

the Vice Chancellor’s desire not to award deal price minus synergies could be seen—

in light of his letter to the parties and the overall tone of his opinion and reargument

decision—as a results-oriented move to generate an odd result compelled by his

personal frustration at being reversed in Dell. Indeed, the idea of awarding the stock

price came into the proceedings from the Vice Chancellor himself after requesting

supplemental post-trial briefing on the matter.59 Prior to that point, neither party

argued for that figure as the fair value under § 262. Because the Vice Chancellor

59
Based on our reading of the record, neither party requested supplemental briefing after our
opinion in Dell issued. And neither party asked the Court of Chancery to set fair value at the
unaffected market price until long after trial, when the Vice Chancellor sent a letter to the parties
requesting supplemental submissions to address the implications of this Court’s decision in Dell.
App. to Answering Br. at B74–75 (Letter from the Court of Chancery to the Parties). After that
letter explicitly requested information about the market attributes of Aruba’s stock, Aruba pivoted
from its previous reliance on its expert’s discounted cash-flow model and the deal price minus
synergies to ask for the first time that the court set fair value at the unaffected thirty-day average
market price of $17.13 per share. See App. to Opening Br. at A1014 (Respondent’s Supplemental
Post-Trial Br. on Dell).

21
introduced this issue late in the proceedings, the extent to which the market price

approximated fair value was never subjected to the crucible of pretrial discovery,

expert depositions, cross-expert rebuttal, expert testimony at trial, and cross

examination at trial. Instead, the Vice Chancellor surfaced Aruba’s stock price as

an appropriate measure of fair value in a way that is antithetical to the traditional

hallmarks of a Court of Chancery appraisal proceeding. The lack of a developed

record on whether the stock price was an adequate proxy for fair value buttresses

our holding that the Court of Chancery abused its discretion by awarding the thirty-

day average unaffected market price of $17.13 per share.

These procedural issues relate to substance in an important way. The reason

for pretrial discovery and trial is for parties to have a chance to test each other’s

evidence and to give the fact-finder a reliable basis to make an ultimate

determination after each side has a fair chance to develop a record and to comment

upon it. The lack of that process here as to the Vice Chancellor’s ultimate remedy

is troubling. The Vice Chancellor slighted several important factors in choosing to

give exclusive weight to the unaffected market price. Under the semi-strong form

of the efficient capital markets hypothesis, the unaffected market price is not

assumed to factor in nonpublic information. In this case, however, HP had signed a

confidentiality agreement, done exclusive due diligence, gotten access to material

nonpublic information, and had a much sharper incentive to engage in price

22
discovery than an ordinary trader because it was seeking to acquire all shares.

Moreover, its information base was more current as of the time of the deal than the

trading price used by the Vice Chancellor. Compounding these issues was the reality

that Aruba was set to release strong earnings that HP knew about in the final

negotiations, but that the market did not. As previously noted, Aruba’s stock price

jumped 9.7% once those earnings were finally reported to the public. None of these

issues were illuminated in the traditional way, and none of them were discussed by

the Court of Chancery in a reasoned way in giving exclusive weight to a prior trading

price that was $7.54 below what HP agreed to pay, and well below what Aruba had

previously argued was fair value.

This multitude of concerns gives us pause, as does the evident plausibility of

Verition’s concern that the trial judge was bent on using the thirty-day average

market price as a personal reaction to being reversed in a different case. In a

reargument decision addressing the petitioner’s argument to this effect, the Vice

Chancellor denied that this was the case.60 We take him at his word. However, so

too do we take him at his word that he viewed an estimate of deal price minus

synergies as compelling evidence of fair value on this record but that he could not

agency costs, and also lacked confidence in his underlying synergy deduction.61

Nevertheless, fixing the double counting problem and hewing to the record

developed by the parties themselves leaves a reliable estimate of deal price minus

synergies,62 which is the one that Aruba advanced until the Vice Chancellor himself

injected the thirty-day average market price as his own speculative idea. Of course,

estimating synergies and allocating a reasonable portion to the seller certainly

involves imprecision, but no more than other valuation methods, like a DCF analysis

that involves estimating (i) future free cash flows; (ii) the weighted average cost of

capital (including the stock’s beta); and (iii) the perpetuity growth rate. But here

there is no basis to think Aruba was being generous in its evaluation of deal price

61
Aruba, 2018 WL 922139, at *51–54.
62
The Vice Chancellor’s view that he had to further deduct additional agency costs is not only
flawed for the reason we mentioned, it was in tension with his own reasoning. The Vice Chancellor
believed that the negotiators for Aruba were not as skilled or as vigorous as he would have been
in risking getting no deal from a bidder that was bidding well above the company’s unaffected
market price and that was bidding well above a level of any interest to any other logical buyer, and
that Aruba therefore did not get as big a share of the synergies as he viewed possible. See Aruba,
2018 WL 922139, at *45 (opining that Aruba “obtained a relatively low share of the synergies
from HP” and therefore that the deal price minus synergies was “north of $18.20 per share,” yet
nevertheless concluding that the deal price minus synergies was $18.20 per share). See generally
Lawrence A. Hamermesh & Michael L. Wachter, Finding the Right Balance in Appraisal
Litigation: Deal Price, Deal Process, and Synergies, 73 BUS. LAW. 961, 1005–06 (2018) (“[A]
perception that bargaining was relatively weak may imply that the target’s stockholders received
a relatively smaller share of overall synergies, and vice versa.”). If this was so, we perceive no
rational basis in the record for his finding that Aruba’s own $19.10 per share estimate was too
high.

24
minus synergies. And, as any measure of value should be, Aruba’s $19.10 deal price

minus synergies value is corroborated by abundant record evidence.63

The Vice Chancellor himself concluded that because the HP–Aruba

transaction involved enormous synergies, “the deal price . . . operates as a ceiling

for fair value.”64 That conclusion was abundantly supported by the record. Aruba’s

estimate of $19.10 resulting from that method was corroborated by HP’s and

63
See supra note 39. Straining to justify a victory on a ground and at a value level it never sought
at trial, Aruba disavowed in oral argument the deal price minus synergies method. We chalk up
this about-face to a litigant receiving a more favorable outcome than they argued for and trying to
cement that unexpected victory on appeal. In the actual record of the case developed and
completed in full before the Vice Chancellor pressed an issue not raised by any party, Aruba’s
expert report contained an entire section on the deal price minus synergies method, its briefs
contained full sections arguing for the Court of Chancery to adopt it, and Verition was given a full
opportunity—which it took—to respond at length to these arguments. See App. to Opening Br. at
