THOMAS O’KEEFE, ET AL., CIVIL ACTION
Plaintiffs
VERSUS NO. 24-2094
SMOOTHIE KING FRANCHISES, SECTION: “E” (3)
INC., ET AL.,
Defendants
ORDER AND REASONS
Before the Court is Defendants Smoothie King Franchises, Inc.’s (“Smoothie
King”) and SK USA Inc.’s (“SK USA”) (collectively, “Defendants”) Motion to Exclude the
Testimony of Craig McCann.1 Plaintiffs Thomas O’Keefe, Kenneth Cunningham, Joseph
Lewis, Brian Judge, Byounghoon Ahn, Dione Heusel, Betsy Riggs, and Thomas West
(sometimes collectively referred to as “Plaintiffs”) filed an opposition.2 Defendants filed a
reply.3
FACTUAL BACKGROUND
This action arises out of Defendants’ allegedly wrongful decision to terminate
Plaintiffs’ stock options in SK USA, Inc.4 Plaintiffs are former executives and employees
of Defendant Smoothie King.5 Plaintiffs allege that on various dates, as part of their
employment with Defendants, Defendants granted them stock options exercisable in the
event Defendants engage “in an initial public offering or a private, change-in-control

transaction.”6 Plaintiffs allege in their amended complaint that, “at the time their
employments ceased, each Plaintiff’s SK-USA Options had either fully or partially vested,
such that each Plaintiff who had been offered SK-USA Options had some number of
vested SK-USA Options.”7 Plaintiffs allege they all ceased employment with Smoothie
King more than three months before filing suit.8
Plaintiffs allege the first time any Plaintiff learned that Defendants considered the
stock options terminated was during a text exchange on August 28, 2023 between Plaintiff
Thomas O’Keefe and Smoothie King’s Chief Executive Officer, Wan Kim.9 Plaintiffs allege
Smoothie King’s legal department later confirmed Smoothie King’s position that the stock
options had “expired and are no longer available to be exercised.”10 Based on Smoothie
King’s position that Plaintiffs’ stock options were terminated, Plaintiffs filed their original
complaint on August 26, 2024.11 Plaintiffs filed an amended complaint on October 28,
2024.12
Relevant to the instant motion, Plaintiffs engaged expert Craig J. McCann, Ph.D.
and CFA, (“Dr. McCann”), “to provide an analysis of the value of the Plaintiffs’ options on
stock of SK USA.”13 In the conclusion of his expert report, Dr. McCann distilled his
findings down into two opinions:
SK USA Holdings’ recent sale of preferred stock establishes an estimate of
$3,164 per option on Plaintiffs’ options on SK USA Inc.’s common stock
using the OPM backsolve method. This estimate substantially understates
the value of Plaintiffs’ options because the preferred stock offering was
chosen by SK USA Holdings’ controlling shareholder as a method for

extracting between $100 million and $130 million without selling stock.
Based on SK USA Holdings’ revealed preference to not sell stock in order to
raise the funds its CEO wished to withdraw I conclude the Plaintiffs’ options
were worth $3,337 to $3,619 per contract.
Table 2 summarizes the value of Plaintiffs’ options for various SK USA
Holdings’ equity values in the range I see supported by the facts in this case.
The options are certainly worth more than the $3,164 implied by the OPM
backsolve method. I believe, consistent with private equity bids and SK USA
Holdings’ executives’ sworn testimony that SK USA Holdings equity value
was between $700 million and $800 million and therefore the Plaintiffs’
options were worth between $3,246 and $3,743 per contract.14
In the instant motion, Defendants request that the Court exclude Dr. McCann’s
testimony entirely.15 Defendants do not contest Dr. McCann’s qualifications as an
expert.16 Instead, Defendants move to exclude his testimony for three reasons: (1) Dr.
McCann failed to adhere to the applicable professional standards in his field; (2) Dr.
McCann’s stock valuation opinions focus on irrelevant time frames; and (3) there is too
great an analytical gap between the facts of this case and Dr. McCann’s analysis.17
Plaintiffs oppose the motion arguing Dr. McCann is qualified to offer his expert opinions
and overall offers relevant and admissible opinions based on sufficient facts and data.18
LEGAL STANDARD
Rule 702 of the Federal Rules of Evidence governs the admissibility of expert
witness testimony:
A witness who is qualified as an expert by knowledge, skill, experience,
training, or education may testify in the form of an opinion or otherwise if:
(a) the expert’s scientific, technical, or other specialized knowledge will help
the trier of fact to understand the evidence or to determine a fact in issue;
(b) the testimony is based on sufficient facts or data; (c) the testimony is the

product of reliable principles and methods; and (d) the expert has reliably
applied the principles and methods to the facts of the case.19
The threshold inquiry is whether the expert witness possesses the requisite qualifications
to render an opinion on particular subject matter.20 If the expert’s qualifications are found
to be sufficient, the court must then examine whether the expert’s opinions are reliable
and relevant.21
The United States Supreme Court’s decision in Daubert v. Merrell Dow
Pharmaceuticals, Inc.,22 provides the analytical framework for determining whether
expert testimony is admissible under Rule 702. “Under Daubert, Rule 702 charges trial
courts to act as ‘gate-keepers,’ making a ‘preliminary assessment of whether the reasoning
or methodology underlying the testimony is scientifically valid,’”23 and of whether that
reasoning or methodology “can be reliably applied to the facts of the case.”24 The party
offering the expert opinion must show by a preponderance of the evidence that the
expert’s testimony is reliable and relevant.25
“[E]xpert testimony proffered” must be “sufficiently tied to the facts of the case
that it will aid the jury in resolving a factual dispute.”26 This is essentially a relevance
requirement.27 With respect to the proper scope of expert testimony, Rule 704 provides

that “testimony in the form of an opinion or inference otherwise admissible is not
objectionable because it embraces an ultimate issue to be decided by the trier of fact.”28
Nevertheless, “[i]f the expert’s testimony brings no more to the finder of fact than the
lawyers can offer in argument, the expert’s opinions should be excluded.”29
As a general rule, questions relating to the bases and sources of an expert’s opinion
affect the weight of the evidence rather than its admissibility, and should be left for the
finder of fact.30 Thus, “[v]igorous cross-examination, presentation of contrary evidence,
and careful instruction on the burden of proof are the traditional and appropriate means
of attacking shaky but admissible evidence.”31 The Court is not concerned with whether
the opinion is correct, but whether the preponderance of the evidence establishes that the
opinion is reliable.32 “It is the role of the adversarial system, not the court, to highlight
weak evidence.”33
Rule 702 requires an expert to base his or her testimony on “sufficient facts or
data.” This requires exclusion of opinions based on “insufficient, erroneous
information.”34 But experts may rely on one version of a disputed fact, and “reliable expert
testimony often involves estimation and reasonable inferences from a sometimes
incomplete record.”35 Thus, the presence of unknown variables in an expert’s opinion do
not necessarily render that opinion unreliable or unhelpful to the jury.36

LAW AND ANALYSIS
Defendants argue the Court should exclude Dr. McCann’s testimony because he
admitted he did not adhere to applicable professional standards in forming his expert
opinions.37 In support of this argument, Defendants point to Dr. McCann’s deposition
testimony.38 Defendants characterize his testimony as an admission that he did not adhere
to the Uniform Standards of Professional Appraisers, the International Valuation
Standards, the American Society of Appraisers’ standards, the National Association of
Certified Valuators and Analysts’ standards, or the Association of International Certified
Professional Accountants’ (“AICPA”) standards in forming his opinions.39 Defendants
further argue Dr. McCann violated industry standard by not using multiple methods to
calculate the value of Plaintiffs’ stock options.40
In opposition, Plaintiffs argue “Dr. McCann did not testify that he failed to follow
[the standards Defendants identify], but rather that as a PhD economist and CFA who is
not a member of those other organizations, he is not bound by pronouncements about
how their members [of those organizations] must perform services.”41 Plaintiffs argue
Dr. McCann’s report and analysis comply with Federal Rule of Evidence 702 because “the
Backsolve OPM that Dr. McCann applied is approved by the AICPA as the preferred
method for valuing private company securities when available, has been accepted by
courts, and Dr. McCann explained why he did not apply other valuation methods.”42
Next, Defendants argue for exclusion of Dr. McCann’s testimony based on the

dates he valued the Plaintiffs’ stock options.43 Defendants argue Dr. McCann’s stock
valuation opinions are irrelevant because Dr. McCann assessed the value of Plaintiffs’
stock options on August 26, 2024 and June 6, 2025.44 According to Defendants, the
relevant date for the valuation of Plaintiffs’ stock options is the date the alleged breach of
contract occurred.45 In response to Defendants’ interrogatories, Plaintiffs stated “their
SK-USA Options were cancelled and converted, without Plaintiffs’ knowledge and to
Defendants’ unjust enrichment, on or about December 15, 2020.”46 Defendants argue this
is the relevant date to value Plaintiffs’ stock options.47
Finally, Defendants argue for the exclusion of Dr. McCann’s testimony because
there is too great an analytical gap between the facts Dr. McCann considered and his
opinions.48 In support of their “analytical gap” argument, Defendants make five
underlying arguments: (1) Dr. McCann did not account for the non-marketability of
Plaintiffs’ options; (2) Dr. McCann makes several “unsubstantiated assumptions”; (3) Dr.
McCann’s valuation opinions rely on a preferred stock transaction rather than a common
stock transaction; (4) Dr. McCann’s valuation opinions assume “that Plaintiffs’ stock
options entitle them to money”; and (5) Dr. McCann did not evaluate a third-party
valuation of Smoothie King from 2024.49

The criticisms raised by the Defendants all are related to the bases and sources for
Dr. McCann’s opinions. “[T]he trial court’s role as gatekeeper is not intended to serve as
a replacement for the adversary system.”50 “Vigorous cross-examination, presentation of
contrary evidence, and careful instruction on the burden of proof are the traditional and
appropriate means of attacking shaky but admissible evidence.”51 “As a general rule,
questions relating to the bases and sources of an expert’s opinion affect the weight to be
assigned that opinion rather than its admissibility and should be left for the [factfinder’s]
consideration.”52 “Furthermore, experts may rely on one version of disputed facts in
forming their opinions.”53 “Any weaknesses in his testimony based on questionable
assumptions may be dealt with on cross-examination.”54 Even “arguments [that] attack
the weight of [an expert’s] methodology . . . may be explored on cross-examination.”55 It
is “the role of the adversarial system, not the court, to highlight weak evidence.”56
Dr. McCann clearly is qualified to express the opinions he has provided in this case.
In fact, the Defendants do not question his qualifications. The Court finds Dr. McCann’s
opinions to be relevant and reliable and finds that his testimony will aid the jury in
resolving the factual dispute as to the value of the Plaintiffs’ stock options. The Court is
convinced that Dr. McCann’s reasoning is scientifically valid. The objections to Dr.

McCann’s testimony relate to the bases and sources of his opinion and, as a result, affect
the weight of the evidence rather than its admissibility, and should be left for the finder
of fact.57 The Court is convinced the Defendants’ will effectively cross-examine Dr.
McCann as to the bases and sources of his valuation opinions and will highlight any
weaknesses in his testimony for the benefit of the jury.
CONCLUSION
IT IS ORDERED that Defendants’ Motion to Exclude the Testimony of Craig
McCanns’ is DENIED.
