GLASSCOCK, Vice Chancellor
      The Defendant, Takeda Pharmaceutical Company Limited (“Takeda”), is a

producer of pharmaceutical drugs, including a drug used to treat cancer, Lupron

Depot (“Lupron”). The Plaintiff, AbbVie Endocrine Incorporated (“AbbVie”), is a

distributor of Lupron under a contract with the Defendant which requires Takeda to

supply Lupron sufficient to meet Plaintiff’s needs as expressed by AbbVie’s “firm

orders.” In 2019, however, Takeda found it necessary, intermittently, to shut down

one of the plants at which it manufactured Lupron, rendering it unable to supply the

Plaintiff’s requirements and creating a shortage for other distributors of the drug

around the world.

      AbbVie sued in this Court, seeking to invoke equity to order the Defendant to

distribute such Lupron as it could manufacture to AbbVie, with priority over other

distributors.   AbbVie also sought contractual damages.         Much litigation has

followed.

      This is my third Memorandum Opinion in the matter. In AbbVie I, I found

that equity could not support the injunctive relief sought by the Plaintiff. In AbbVie

II, I found that Takeda was in breach of its contract with AbbVie, and that its breach

had caused AbbVie cognizable damages.          The current Memorandum Opinion

addresses, post-trial, the quantum of those damages.

      I will not repeat here the extensive factual development pertinent to the issues

in AbbVie I and AbbVie II. Interested readers should consult those opinions. What

follows is a brief statement of only those facts necessary to understand my damages

analysis.    I then address the quantum of those damages and how they were

demonstrated at trial.

                                     I. BACKGROUND1

       Plaintiff AbbVie is a Delaware incorporated drug distributor.2 One drug that

AbbVie distributes is Lupron, whose applications include the treatment of prostate

cancer.3 AbbVie receives its entire supply of Lupron from Defendant Takeda, the

drug’s sole producer.4 This supply relationship is governed by a requirements

contract (the “Supply Agreement”) under which Takeda fulfills AbbVie’s firm

orders.5

       In late 2019, a piece of sterilization equipment failed its annual requalification

test at one of Takeda’s two Lupron-producing facilities.6 This set into motion a

chain of events that resulted in intermittent facility closures and, ultimately, a period

resulted.8

       AbbVie brought suit for breach of contract in November 2020,9 together with

motions for a preliminary injunction, which I denied, and for expedition, which I

granted.10 Following discovery, a four-day trial (“Phase I”) was held on the issues

of Takeda’s liability under the Supply Agreement and the appropriateness of final

injunctive relief.11 In AbbVie I, I held that the injunctive relief Plaintiff sought would

be unworkable.12 In AbbVie II, I determined that Takeda was liable for breaching

the Supply Agreement.13

       A second, three-day, trial (“Phase II”) was held in January 2023 to determine

“the quantum of cognizable damages—if any[.]”14 Post-trial oral argument for

Phase II was held on May 18, 2023, and I consider the matter fully submitted as of

that date.15

                                    II. ANALYSIS

      The principal question before me is whether AbbVie has carried its burden

of presenting the Court with a responsible, non-speculative estimate of damages. I

begin by dealing with a number of threshold legal questions, including the

appropriate choice of law, measure of damages, and burden of proof. From there, I

move to an assessment of AbbVie’s damages estimation methodology, which is the

focal point of the parties’ Phase II disputes. Following a brief overview of that

methodology, I delve one-by-one into the disputed inputs. Finally, I address

Takeda’s arguments that any recovery should be reduced, or even eliminated, due

to AbbVie’s purported failures to mitigate or show causation.


      A. Legal Standard

             1. Delaware Law Applies to Phase II

      My decision in AbbVie II applied Illinois law in determining that Takeda had

breached the Supply Agreement, the “validity and interpretation” of which is

governed by that state’s law.16 The Supply Agreement also provides that:

      Except as otherwise provided in this Agreement, any and all disputes
      arising out of or relating to this Agreement shall be governed by Section
      15.05 of the [Contribution and Exchange Agreement, dated as of March
      19, 2008, and amended and restated as of April 30, 2008 (the
      “CEA”)].17

16
   See AbbVie II; Phase I PTO ¶ 26. The parties further stipulate that the Contribution and
Exchange Agreement is a valid and enforceable contract. Id. ¶ 13.
17
   Phase I PTO ¶ 27. The parties have further stipulated that the CEA governs the Supply
Agreement. Id. ¶ 28.

                                            4
The CEA contains a broad choice of law provision applying Delaware law to

disputes, “except as otherwise explicitly provided[.]”18 Reading the two agreements

together, “all disputes arising out of or in connection with” the Supply Agreement

are assessed under Delaware law unless an explicit carve-out, such as the one made

for “validity and interpretation[,]” applies.19 Accordingly, Delaware law governs

this damages determination because no such carve-out applies.20

               2. The Measure of Damages

       “[U]nder Delaware law, the standard remedy for breach of contract is based

on the reasonable expectations of the parties that existed before or at the time of the

breach.”21 Expectation damages “require the breaching promisor to compensate the

promisee for the promisee's reasonable expectation of the value of the breached

contract, and, hence, what the promisee lost.”22 Lost profits are an accepted means

of quantifying expectation damages in a breach of contract action.23 However, “no

   Defendant’s post-trial briefing does not discuss the choice of law issue and relies almost entirely
on Delaware caselaw. See Def. Takeda Pharm. Co. Ltd.’s Corrected Post-Trial Opening Br.
(“Takeda PTOB”), Dkt. No. 442; Def. Takeda Pharm. Co. Ltd.’s Answering Post-Trial Br.
(“Takeda PTAB”), Dkt. No. 432. Therefore, to the extent Defendant disputes the application of
Delaware law, such an argument is deemed waived. See Emerald P’rs v. Berlin, 726 A.2d 1215,
1224 (Del. 1999) (“Issues not briefed are deemed waived”) (citations omitted).

recovery can be had for loss of profits which are determined to be uncertain,

contingent, conjectural, or speculative.”24

               3. Burden of Proof

       I noted in AbbVie II that the burden remains on AbbVie to prove “the quantum

of cognizable damages[.]”25 While a plaintiff must prove the fact of damages by a

preponderance of the evidence, the “proof required to establish the amount of

damage is not as great as that required to establish the fact of damage.” 26 Indeed,

showings of future lost profits need only meet the more relaxed “substantial

evidence” standard,27 requiring “such relevant evidence that a reasonable mind

might accept as adequate to support a conclusion.”28

       Here, the fact of damages is established by my holding in AbbVie II “that

AbbVie has experienced injury sufficient to sustain a finding of liability[.]”29 As a

result, AbbVie’s showing of the amount of damages “can be an estimate, uncertain,

estimate”31 that goes beyond “mere ‘speculation or conjecture[.]’”32

                      a. The Wrongdoer Rule

        AbbVie argues that, in addition to this reduced burden, “[a]ny uncertainty in

the damages calculation that can be traced to Takeda’s breaches is presumptively

resolved against Takeda” under the so-called “wrongdoer rule.”33 For its part,

Takeda contends that “the wrongdoer rule [only] applies to bad-faith or willful

breaches.”34

        This Court has previously acknowledged the inherent imprecision involved in

crafting a remedy based on a hypothetical “but-for” world in which no breach

occurred.35 This complex reality is reflected in the discretion afforded to trial courts

in shaping remedies that reflect the facts and circumstances of a specific case.36 The

wrongdoer rule AbbVie articulates is, at its core, just one form this discretion can

take.

       Previous cases in which the Court employed AbbVie’s preferred approach to

resolving uncertainty all involved either bad faith or willful37 action on the part of

the defendant.38 My decisions in AbbVie I and II made no finding that Takeda

breached the Supply Agreement willfully or in bad faith, nor has AbbVie

subsequently made such a showing.39 Accordingly, I decline to apply the wrongdoer

rule as articulated by AbbVie. I do so because I find that the reduced burden of proof

described above appropriately balances AbbVie’s uncertainty concerns against

Takeda’s lack of wrongful intent.

       B. The Damages Model

       The next issue before me is the appropriateness of AbbVie’s damages model.

Takeda challenges the fundamentals of this model on two grounds: AbbVie’s

purported data manipulation and the overall methodology used to estimate damages.

I examine both of these arguments below.

             1. AbbVie’s Alleged Data Manipulation

      Takeda contends that AbbVie intentionally inflated its Lupron orders during

the course of litigation in order to maximize its eventual damages.40 Per Takeda,

this “matters because a significant percentage of AbbVie’s claimed damages . . .

depend on AbbVie’s own projections of future Lupron sales and profits.”41 But

Takeda entirely neglects to explain how inflated order volume impacts AbbVie’s

damages calculations.42 Indeed, order volume is not a component of AbbVie’s

damages model.43 To the best of my understanding, Takeda instead invites me to

approach all AbbVie-generated data with skepticism, given AbbVie’s allegedly

underhanded approach to order volume. Such an inference, drawn post-trial, must

be adequately supported by the record. As discussed above, Takeda cannot marshal

sufficient arguments, let alone evidence, to support its desired inference.

Accordingly, my assessment of AbbVie’s model, including its inputs, is based solely

on the evidence in the record, free of adverse inferences.

             2. Methodology

      AbbVie’s damages estimate is drawn from the expert report of economist Dr.

Christine Meyer.44 While I address various contested components of Dr. Meyer’s

                                           9
damages model in greater detail below, I provide a generalized overview here in

order to better address Takeda’s critiques.

       The model’s central premise is that the Lupron shortage caused customers to

jump to competitors’ products, costing AbbVie sales and, in some cases,

permanently eroding Lupron’s market share due to market characteristics that make

a switch back unlikely.45 Dr. Meyer begins by breaking damages out into three

categories based on Lupron’s principal applications: urology (“URO”), pediatrics

(“PED”), and gynecology (“GYN”).46 Both URO and PED are further divided into

past and future damages, given AbbVie’s allegations that the shortage’s impacts will

continue for years to come.47

                       a. Estimation of URO and PED Damages

       Dr. Meyer calculates past damages for the URO and PED segments by taking

the difference between an estimated pre-shortage baseline and the actual sales data

for a given post-shortage month.48 After making necessary adjustments, such as for

the post-shortage launch of a new competitor drug, Dr. Meyer then multiplies this

difference by the actual average selling price per unit for that year.49 Finally, she

48
   Id. at 0047, 0059, 0081, 0091.
49
   Where the data manipulations employed are identical for URO and PED, I cite only to the URO
section of Dr. Meyer’s report discussing those calculations. See, e.g., id. at 0054 (discussing this
calculation for the URO segment). For 2022 calculations, Dr. Meyer used AbbVie’s internal price
projections. Id.

                                                10
incorporates the incremental costs AbbVie would have incurred in selling those

units.50 This results in a dollar figure representing AbbVie’s estimate of its lost

profits due to lost sales in that segment through October 2022.51

       AbbVie’s estimate of future URO damages aims to quantify the difference

between (a) the profits AbbVie would have earned from October 2022 through 2031

had there been no shortage and (b) the reduced profits it expects to earn in the real

world during that same period.52 The URO model incorporates sales and pricing

projections from the expert report of Edward Buthusiem with data on that market

segment’s expected growth rate, yielding a dollar estimate of damages.53 Dr. Meyer

then discounts this figure to its present value using AbbVie’s weighted-average cost

of capital (“WACC”).54

       AbbVie projects that the impact of the shortage on future PED profits will

have concluded in June 2023.55 Per AbbVie, the shortage provided a timely boost

to a new market entrant, Fensolvi, allowing that drug to capture a larger market share

than it otherwise would have.56 Dr. Meyer therefore begins calculating future

damages by taking the difference between Lupron’s pre-shortage PED market share,

adjusted downward to account for competition from Fensolvi but not the shortage-

induced boost, and Lupron’s post-shortage market share projected forward.57 These

lost sales figures are then combined with sales price projections, as well as estimated

costs, before being discounted to the present value.58

                     b. Estimation of GYN Damages

       AbbVie seeks only past damages for the GYN segment.59 Because Lupron

sales in the GYN market vary considerably from month to month, Dr. Meyer

employs a three-month rolling average to smooth this volatility.60 She then uses this

smoothed data as a baseline against which to compare the post-shortage data, finding

that AbbVie lost sales through October 2021.61 Dr. Meyer then uses AbbVie’s

pricing and incremental cost data to convert those lost sales into a dollar figure

damages amount.62

                     c. Incidental Damages

       The final piece of AbbVie’s damages estimate involves two additional

categories of past damages not specifically associated with one of the three major

Lupron applications. The first category involves additional testing fees that AbbVie

incurred to ensure that certain shipments of Lupron received from the troubled

incurred penalties from the federal government due to pricing penalties resulting

from the shortage.64

                      d. Takeda’s Critiques

       Though Takeda’s economic expert, Dr. Michal Malkiewicz, adopts Dr.

Meyer’s methodology in his own damages estimate,65 Takeda contends that this does

not constitute an endorsement and that “Takeda has conceded nothing with respect

to the cause or amount of AbbVie’s alleged lost profits.”66 Despite this explicit lack

of concession, Takeda’s arguments focus on the model’s inputs and assumptions,

leaving the overarching methodology untouched.67 I find that the damages model

employed by the parties is capable of producing a reliable, non-speculative

estimation of damages. Accordingly, I adopt it.68

       I address Takeda’s critiques of various model inputs below.

       C. Damages Calculation

       Having found Dr. Meyer’s damages calculation methodology fundamentally

reliable, I turn now to the principal source of the parties’ disputes: the model’s

    For the avoidance of doubt, the Court also adopts the numerous inputs and assumptions
underlying this model. To the extent a given input or assumption is not addressed in this opinion,
it is because I find it reasonable.

inputs. Below, I carefully assess each dispute, finding most of AbbVie’s proposed

inputs reasonable, with a key exception.

      In the following brief paragraphs, I present an overview of the disputes

between the parties before beginning a more detailed analysis. Finally, having

adopted AbbVie’s fundamental damages model and resolved the disputes as to

inputs and application, I conclude by asking the parties to apply these rulings by

computing the appropriate damages figure.

       I begin with an analysis of the appropriate discount rate, finding it more

sensible to apply AbbVie’s overall WACC, as calculated by the market, than the

company’s internal “hurdle rate.” Turning to the URO market segment, I find

AbbVie’s proposed 22-month benchmark credible in light of Lupron’s stable market

share pre-shortage. I further find that AbbVie’s estimated growth rate for the URO

market is reasonable in light of both the actual data and competitors’ projections.

While AbbVie has shown its 2022 pricing update succeeded in stabilizing Lupron

URO’s falling prices, the company fails to establish that the update will allow it to

steeply increase prices through 2031 without losing sales as it contends.

      The only adjustment I make to AbbVie’s PED damages estimate is the

removal of a disputed period of volatility immediately preceding the shortage. I find

AbbVie’s estimate of GYN damages reasonable and decline to make Takeda’s

requested adjustments. Turning to AbbVie’s claims for incidental damages, I find



                                           14
that it is entitled to some, but not all, of the damages it seeks. Finally, I find that,

because Takeda’s arguments on AbbVie’s failure to mitigate or establish causation

are unpersuasive, AbbVie is entitled to expectation damages as well as

accompanying pre- and post-judgment interest.

      My reasoning follows.

             1. Discount Rate

      Generally, a discount rate consists of a component representing the time value

of money as well as a premium representing the risks associated with that specific

investment.69 Here, the risk premium represents the uncertainty associated with

AbbVie’s ability to achieve its projected profits.70 As touched on briefly in Section

II.2.A, the discount rate is used in the parties’ damages models to discount estimates

of future damages to their present value. A higher number will, all else equal, result

in a correspondingly lower present value.

      Both parties’ experts use AbbVie’s WACC as their discount rate, reflecting

the average cost the company must pay its investors for their capital.71 They differ

in the source (and size) of the WACC. AbbVie proposes that the Court use the

company’s enterprise-level WACC of 6.6%, as calculated by Bloomberg.72 In

contrast, Takeda argues that the Court should apply the 8.0% WACC AbbVie uses

as its “hurdle rate,” given that this is the figure AbbVie uses internally to calculate

the net present value of potential future investments.73 Per Takeda’s expert,

      [The] [h]urdle rate is a minimum rate that a company expects to earn
      from its investment project. Thus, in order to be accepted, the estimated
      project’s rate of return should exceed the company’s hurdle rate.
      Hurdle rate is also used as a discount rate to calculate the net present
      value of investment. Hurdle rate can be adjusted up or down by a
      company to reflect relevant risks of the specific investment project.
      Therefore, it is a better measure of the discount rate for a specific
      project (the Lupron franchise) that incorporates all relevant risks.74

This assessment draws a tenuous conclusion from a correct, if incomplete, overview

of its technical underpinnings.      A company uses its internal hurdle rate as a

benchmark against which to assess which projects it should prioritize given limited

time and funds.75 While a hurdle rate can be “adjusted up or down by a company to

reflect relevant risks of the specific investment project[,]” that is not the case where,

as here, a company uses a single company-wide hurdle rate that is only adjusted

periodically.76 Instead, a company may opt to adjust its hurdle rate upwards for

various reasons unrelated to a given project’s risk,77 including a prioritization of the

most profitable projects in a research and development intensive industry.

      I find that the evidence in the record supports a conclusion that the risks

associated with AbbVie’s Lupron profits through 2031 align more closely with the

company’s risk as a whole. I further find credible Dr. Meyer’s testimony that

AbbVie’s proposed discount rate of 6.6% may overstate the risk for a mature drug

like Lupron, given that Bloomberg’s estimate of the company-wide WACC includes

the risk of nascent drugs in development.78 Combined with my determination, infra,

that Lupron enjoyed a steady market share prior to the shortage, I conclude that

AbbVie has carried its burden in showing that its proposed discount rate of 6.6% is

an appropriate approximation.

              2. URO – Past Damages

      Takeda’s principal dispute with AbbVie’s estimate of past URO damages is

the length of the benchmark period used to calculate Lupron’s baseline market

share.79 As discussed above, this baseline is used to calculate the resulting post-

shortage drop in sales for a given month. Here, Dr. Meyer’s benchmark period runs

from October 2018 through July 2020,80 resulting in a stable baseline market share

of 64.3%.81

       While Takeda faults this benchmark for excluding nearly two years of data,82

AbbVie presents compelling evidence in favor of the shorter period. AbbVie argues

that “the oldest available data contains a subtle downward trend that is not present

in later data.”83 Per AbbVie, that downward trend was replaced by the current

stability.84   As supporting evidence, AbbVie points to pre-shortage internal

documents, as well as testimony.85 Indeed, the stable baseline AbbVie projects is

robust to adjustments of the benchmark period by up to one year (i.e., as short as 10

months or as long as 34 months).86

       Takeda argues that this “‘robustness analysis’ was outcome driven” and

obscures “Lupron’s historically declining market-share due to growing

competition.”87 Takeda bases this argument on select pieces of testimony from

AbbVie employees and vague contentions that Dr. Meyer’s exclusion of the oldest

data was unjustified.88 It has no real answer to the argument, borne out in the data,

that Lupron URO’s market share had reached a stable equilibrium prior to the

shortage.89

       Accordingly, I find that AbbVie has carried its burden in showing that Lupron

URO enjoyed a stable market share prior to the shortage and that a 22-month

benchmark is appropriate.

               3. URO – Future Damages

       Turning to future URO damages, two disputed inputs remain before me: the

market growth rate and AbbVie’s “universal update” pricing changes.90

                       a. URO Market Growth Rate

       AbbVie assumes an approximately 2.9% annual growth rate through 2030 for

the relevant androgyn deprivation treatment (“ADT”) market segment.91 This figure

is drawn from AbbVie’s January 2020 Long-Range Plan92 and is purportedly


89
   See Takeda PTAB at 31–33 (fielding only conclusory accusations that Dr. Meyer erred by
excluding the “stale” data).
90
   Takeda contends that there is a third dispute: the impact of 2022 market entrants in the form of
Camcevi and Lutrate, which it argues AbbVie’s model fails to account for. Takeda PTOB at 63–
64. This argument is too little, too late. Though Takeda argues that it “can illustrate AbbVie’s
mistakes without bearing the burden of soundly modeling their impact[,]” Takeda PTAB at 17,
Takeda cannot credibly argue the materiality of these competitors or their impact on AbbVie’s
model without some quantifiable evidence, which was not presented at trial. Perhaps realizing
this, on the eve of post-trial argument, Takeda filed a motion to supplement the trial record, which
included amended models purporting to estimate impact of the new URO competitors. Defs.’ Mot.

expert opinions, I granted AbbVie’s motion to strike. Pl.’s Opp’n to Mot. to Suppl. the Trial R.
and Cross-Mot. to Strike, Dkt. No. 427; Letter Op., Dkt. No. 438. Because Takeda’s arguments
here do not find sufficient support in the current record, such that they can move beyond mere
speculation, I need not address them further.

consistent with the United Nations’ growth projections for ADT’s primary target

demographic.93 Takeda argues for a growth rate of 1.75% per year citing a 2019

GlobalData report on the ADT market,94 further informed by expert testimony.95

       AbbVie contends that the GlobalData report Takeda relies on is stale and has

not been borne out by IQVIA’s96 ADT market data since 2019.97 Indeed, outside of

the shortage’s impact in 2020, GlobalData’s estimate underpredicts the actual data,

as reported by IQVIA, by at least 2% for each year from 2018 to 2022.98 While

Takeda attacks AbbVie’s use of United Nations’ demographic data, which includes

women, as an inappropriate proxy for the growth of the overwhelmingly male ADT

market,99 the data in question is merely one of a handful of sources AbbVie uses to

validate its estimate.100 Takeda declines to directly address the shortcomings of the

GlobalData report.101 Accordingly, I find that, absent credible evidence of an

impending drop in demand for ADT, AbbVie’s estimated growth rate of 2.9% is

both consistent with recent data and reasonably conservative.

       Takeda draws upon the opinion testimony of its expert medical oncologist,

Dr. Marc Garnick, to argue “that the standard of care is shifting, and the relative use

of ADT will decrease.”102 This impending decrease, per Takeda, merits a downward

adjustment of the ADT market segment’s future growth.103 I found Dr. Garnick to

be an inspirational and persuasive witness in his discussion of the future of treatment

for prostate cancer. However, I find that Dr. Garnick’s opinion testimony does not

justify the adjustment Takeda seeks. Dr. Garnick, in both his expert report and trial

testimony, discussed recent “leading-edge” advances in the identification and

treatment of prostate cancer, concluding that ADT’s “usage will diminish[.]”104

However, Dr. Garnick’s report offers very little explanation of when this change will

occur and how fast it will take place.105 Thus, I find that, even if I agree with Dr.

Garnick’s ultimate conclusion that ADT usage will eventually diminish, Takeda has

not marshalled evidence showing that this diminution will occur by 2031, such that

a significant downward adjustment of AbbVie’s otherwise reasonable estimated

growth rate for the ADT market is merited.

                    b. Universal Pricing Update

      The parties’ next dispute centers on the impact of AbbVie’s 2022 rollout of a

new pricing structure impacting many of its Lupron URO sales channels. This

update aims to increase the average sale price (“ASP”) of future units of Lupron sold

in the URO market, which would, obviously, increase the money damages arising

out of lost sales per unit. This raises two issues: (1) whether the pricing update was

a litigation-driven strategy and (2) whether AbbVie’s estimates of post-update ASP

are credible.

      Takeda argues that “AbbVie’s claim that this radical change to Lupron pricing

was conducted in the ordinary course of business is suspect” because AbbVie had

been aware of Lupron URO’s declining profitability since at least 2015.106 This, per

Takeda, merits scrutiny of AbbVie’s mid-litigation implementation of the

strategy.107 AbbVie retained Boston Consulting Group (“BCG”) in October 2019 to

evaluate its Lupron URO business.108 BCG delivered its recommendations the

following spring.109 Per AbbVie, supply issues had already begun at that point and

the company could not implement the recommendations until supply stabilized.110

Takeda contends that the shortage did not start until August 2020, months after the


106

implemented a pricing update absent the shortage.

were aware of problems at the Hikari plant by spring of 2019.112 Accordingly, I find

AbbVie’s justifications for its delayed implementation of BCG’s recommendations

credible and that Takeda’s contentions to the contrary lack sufficient supporting

evidence.

       AbbVie projects that the pricing update will reverse a decade of declining

ASP in the URO segment. Mr. Buthusiem projects that the overall ASP will increase

in each subsequent year, starting from a low of $141 in 2022 and reaching $177—

or roughly 2015 levels—by 2031.113 In order to rectify declining profitability in the

indirect sales channel, purportedly borne out of an inconsistent patchwork of

discounts and elevated wholesaler fees,114 AbbVie moved its indirect contracted

customers from fixed price contracts to pricing based on Lupron’s wholesale

acquisition cost (“AC”).115 Under this new formula, the uniform ASP for the indirect

channel would be equal to the AC minus 91.75%, less a 2.05% returns and service

fee.116 AbbVie further plans to increase AC by 4.9% each year through 2031.117

Because the channel subject to this pricing scheme accounts for 27.1% of AbbVie’s

URO sales, these changes are a major driver of the overall rebound in ASP that

AbbVie projects.118

       Takeda argues that AbbVie’s projections lack support in both basic economic

principles and reality. AbbVie’s projections assume that the negative repercussions

of its 4.9% annual price increases will be limited to a one-time drop in sales volume

of 15% in the channel impacted by the pricing update.119 This figure of 15% is

based, it would appear, on a single email between AbbVie employees, rather than

any economic analysis that has been explained in this case.120 Nor does AbbVie

explain how Lupron would maintain both increasing prices and a stable market share

in the face of competition from both Eligard and new market entrants. Instead,

AbbVie argues that evidence of the pricing update’s initial success justifies the

Court’s adoption of Mr. Buthusiem’s ASP projections.121 Evidence that AbbVie’s

pricing update has not caused customer demand to drop is probative of the

company’s ability to stem price erosion in the indirect channel.122 It does not, to my

mind, justify AbbVie’s argument that Lupron will maintain its market share despite

compounding 4.9% price hikes every year through 2031. In short, customers’

tolerance for an indirect channel price of $114.95 in 2022, absent more, does not

prove that they would maintain their purchasing habits in the face of a price of

$176.80 in 2031.123

       Accordingly, I find that, while AbbVie has shown that the pricing update

stabilized the dropping price of Lupron in the indirect channel, it nonetheless fails

to carry its burden of showing that the ambitious price increases it has planned will

not have a negative impact on customer demand. Combined with my finding, infra,

that Lupron URO’s market share was stable with AbbVie’s showing that a stabilized

price has not resulted in customer flight, I therefore find it reasonable that AbbVie

will maintain its 2022 pricing in the indirect channel through 2031.124

              4. PED – Past Damages

       Moving next to the pediatrics market for Lupron, the parties disagree over two

aspects of the benchmark: the extent to which a volatile period from April to August

2020 should be included and the appropriate adjustment for a new competitor drug,

Fensolvi.




123
   See Buthusiem Report at 0065, Fig. 42.
124
   Id. For the avoidance of doubt, the figure I reference is equal to $114.95. I decline to alter
other components of the overall ASP pricing model because Takeda has not presented sufficient
evidence that AbbVie will diverge from its pricing strategy.

                    a. The Appropriate Benchmark Period

      Takeda accuses AbbVie of inflating the benchmark by including data from

April 2020, “in which Lupron market-share was anomalously high.”125 Though

AbbVie acknowledges that April 2020 saw a “spike in market share,” it contends

that both this spike and a subsequent “‘valley’ of lower-than-usual market share” are

related to the drop, and subsequent recovery, in market share of a surgically-

implanted competitor at the beginning of the COVID-19 pandemic.126 Per AbbVie,

by removing the spike and keeping the valley, Takeda “cherry-pick[s]” its data.127

Takeda responds by pointing out that AbbVie’s drop-and-recovery theory lacks

evidentiary support and is further undermined by the fact that the valley “extends

months beyond” the parties’ benchmark period.128 What Takeda fails to mention is

that the mid-point of this extended valley also coincides with the start of backorders

in August 2020, further confounding the analysis.129

      I find that, during the period from April to August 2020, the PED market

experienced a variety of disruptions that contributed to market share volatility,

including both the pandemic and early impacts of the shortage.130 Neither party’s

explanation convinces me that the additional market share information contained in

these datapoints outweighs the noise they bring to the benchmark estimate.

Accordingly, I find that the parties should exclude from the benchmark period all

data from April 2020 onward.

                      b. The Impact of Fensolvi

       The parties further dispute how Lupron PED’s but-for market share should be

adjusted to account for Fensolvi, a competing drug that was launched in June

2020.131     AbbVie takes the position that, because Fensolvi “was launched

contemporaneous with the peak of the [Lupron PED] shortage[,]”132 it received a

competitive boost that allowed it to achieve a larger market share than it otherwise

would have.133 AbbVie therefore models two but-for market share scenarios: one in

which Fensolvi enjoyed no boost from the Lupron shortage, and a second in which

the shortage caused Fensolvi to take some of Lupron’s market share.134 In order to

isolate what piece of Fensolvi’s market share is attributable to the shortage-induced

boost, AbbVie’s economic expert estimates the boost enjoyed by a third, established,

competing PED drug, Triptodur.135 She does so by comparing Triptodur’s post-

shortage market share to a pre-shortage baseline, finding a boost of approximately

                                              27
62%.136 She then applies this and other adjustments to Fensolvi’s market share to

determine what portion of this share would have gone to Lupron in a but-for world,

resulting in an overall upward adjustment of Lupron’s but-for market share

compared with the “no boost” scenario.137

       Takeda disputes two of the assumptions underlying this analysis: Triptodur’s

suitability as a proxy and the degree to which Fensolvi’s growth can be attributed to

the shortage.138 In justifying her choice of Triptodur as a proxy, Dr. Meyer points

out that, other than Fensolvi and Lupron, the main drugs on the market are Triptodur

and Supprelin.139 While Supprelin requires a surgical implant,140 both Fensolvi and

Triptodur are injectables that come in a six-month dose.141 Additionally, Triptodur,

which launched in October 2017, has a similar market share to Fensolvi.142 Despite

these similarities, Takeda argues that Triptodur is an inappropriate proxy because

(1) Fensolvi’s injection is subcutaneous, rather than intramuscular, and (2) Triptodur

is made by Tolmar, the producer of Eligard, which, per Takeda, makes it “a more

potent threat to Lupron-PED than Triptodur.”143 Takeda’s implied argument is that

I should decline any proxy estimation as overly speculative because it is based on a

good but not perfect comparison. I disagree. Because I find Triptodur to be a

reliable proxy for the purposes of calculating Fensolvi’s market share boost, I adopt

it.

       Takeda’s second quarrel with Dr. Meyer’s treatment of Fensolvi is that her

projections fall within AbbVie’s own pre-shortage predictions of Fensolvi’s market

share.144 Per Takeda, this undermines AbbVie’s contention that AbbVie lost market

share to Fensolvi due to the shortage.145 However, while AbbVie’s internal

projections are helpful, they are not dispositive.146             Here, I find credible the

testimony by AbbVie’s Vice President of Endocrinology, Metabolics, and Women’s

Health that AbbVie will routinely “project ambitiously on behalf of” new

competitors for planning purposes, only to “make the correction backwards once the

actuals come in.”147 I therefore find that AbbVie’s pre-shortage predictions do not

fatally undermine the argument that Lupron PED lost market share to Fensolvi as a

result of the shortage.

       Finally, Takeda argues that Fensolvi’s capture of market share is at least partly

attributable to a COVID-driven preference for longer-acting PED formulations.148

Lupron, as the dosage with the shortest duration, would be on the losing end of this

preference.149 However, other than testimony from Dr. Meyer acknowledging this

trend and stating that she accounted for it in her model,150 Defendants can point to

no evidence in the record supporting an alternative adjustment.151 I therefore decline

to diverge from my finding that Dr. Meyer’s adjustments for Fensolvi were

appropriate.

               5. PED – Future Damages

       AbbVie claims future damages in this segment through June 2023, which it

calculates as the difference between the but-for baseline and Lupron PED’s post-

shortage market share, projected forward.152 AbbVie’s expert opines that the real-

world data from December 2021 to October 2022 exhibits no linear trend, suggesting

that Lupron’s share of the PED market post-shortage has flattened.153

       Takeda’s remaining argument boils down to a contention that, by ignoring

favorable data on new patient/therapy starts (“NTS”), AbbVie’s expert

underestimates Lupron’s recovery of market share.154              Per Takeda, NTS data

indicating that 70% of new PED patients are going to Lupron confirms Takeda’s

higher projections of actual market share.155 However, Takeda’s argument ignores

the fact that NTS data, which is limited to prescriptions at retail pharmacies,

undercounts Supprelin, Lupron’s surgically-implanted competitor, by almost two

thirds and excludes Triptodur entirely.156 I therefore find that the NTS data does not

undermine AbbVie’s evidence that a steady post-shortage PED market share is

reasonable.157

              6. GYN

       Takeda contends that AbbVie’s calculation of past damages in the GYN

segment is flawed because it (1) uses an incorrect endpoint and (2) ignores

“cannibalization” of Lupron GYN market share by competing AbbVie drugs.158

Using three-month rolling averages to smooth the extreme volatility of monthly

Lupron GYN sales, AbbVie’s economic expert bases her past damages endpoint on

an assessment of when average sales returned to or exceeded benchmark levels.159

The use of trailing averages, by design, carries a risk of overestimating the length of

the shortage.160 This is because a given month’s average combines the data from

    Takeda also argues that AbbVie’s theory of a stable post-shortage Lupron PED market share
of 50.3% is belied by a single month in which that market share reached 52%. Takeda PTOB at
74–75 (citing Meyer Supplement at 0028). This argument ignores both the historical volatility of
PED market shares and the basic math of averages.

that month as well as the two previous months, giving more weight to the past than

the present.161 This weighting could therefore cause the impact of the shortage to

appear to persist a month or two after it had, in fact, ended. However, I find that,

given the volatility of the monthly sales data, this methodology is the best available

to provide the Court with a reasonable, non-speculative endpoint for past damages

calculation.

       Without challenging the propriety of Dr. Meyer’s rolling average

methodology, Takeda argues that only “actual monthly data” can reveal the

appropriate endpoint for the past damages period.162 Per Takeda, the damages period

should end in January 2021 because its economic expert “performed a regression

analysis on monthly sales, which shows no significant differences between” the

benchmark period and post-January 2021 damages period.163 But the fact that “it’s

really hard to ascertain trends in noisy data” is precisely why AbbVie’s expert

employed rolling averages,164 a methodological decision that Takeda’s expert voiced

no quibbles with.165 Other than a more favorable result (to Takeda), Takeda presents

no argument for why the trends its expert now pulls from this noisy data allay these

concerns or are reliable.166      Further, Takeda declines to respond to AbbVie’s

argument that Takeda’s expert ends the past damages calculation in the middle of

ongoing instances of Lupron GYN customer orders exceeding available

inventory.167 Accordingly, I find that Takeda has presented no evidence to impugn

the reliability of AbbVie’s calculation of the Lupron GYN damages endpoint.

       Takeda next argues that AbbVie overstates its Lupron GYN damages by

ignoring market share cannibalization from two competing AbbVie drugs: Orilissa

and Oriahnn.168     Most of Takeda’s evidence indicates that these are possible

alternatives to Lupron.169 Takeda’s sole piece of evidence that these drugs actually

eroded Lupron’s market share comes from Mr. Buthusiem’s rebuttal report of March

15, 2021, in which he acknowledges that “[i]t appears that Orilissa did erode a

portion of Lupron sales.”170 What Takeda declines to address is that, consistent with

AbbVie’s position that there has been no substitution post-shortage,171 Mr.

Buthusiem concluded that Orilissa’s market share growth and, presumably, any

cannibalization occurred “prior to the July 2020 shortage[.]”172                 Takeda’s

cannibalization argument therefore is not persuasive.

              7. Incidental Damages

       In addition to the lost profits analyzed above, AbbVie also claims damages

arising from additional testing costs and pricing penalties necessitated by the

shortage.173 I find that, while AbbVie fails to carry its burden of proof with regard

to the testing costs, it may recover damages for the pricing penalties incurred as a

result of Takeda’s breach.

       Pre-trial, AbbVie argued that it was owed $1.3 million for testing costs it

incurred after it “told the FDA it would perform additional oversight and testing on

each lot of Lupron coming from [Takeda’s production facility at] Hikari.”174 Post-

trial, AbbVie is curiously vague when it comes to specifics.175 Dr. Meyer’s expert

report notes that $1,187,289 of this testing cost “is the amount that AbbVie paid

Takeda for the Lupron products that were tested.”176 However, AbbVie cites no

evidence indicating that the testing was destructive, or that this cost was not

otherwise recouped.177 AbbVie therefore fails to carry its burden with regard to these

purported costs.178

       AbbVie claims that it suffered an additional $4,341,604 in incidental damages

as a result of “penny pricing” penalties triggered by the shortage.179 The following

is a simplified version of the causal chain alleged: Under the Veterans Healthcare

Act (the “VHA”), AbbVie sells Lupron to federal agencies, at a discount, through

wholesalers.180 Also pursuant to the VHA, AbbVie must report an annual Non-

Federal Average Manufacturer’s Price (“non-FAMP”) to the government based on

a subset of Lupron sales.181 The VHA imposes a pricing penalty if the year-on-year

increase in non-FAMP exceeds the consumer price index.182

       Due to the shortage, Lupron sales in the third quarter of 2020 were

depressed.183 However, chargebacks,184 which typically lag sales data by a month



177
    See id. at 0110 (describing Dr. Meyer’s understanding only that the figure represents what
AbbVie paid); JX 5146 144:13–145:5 (confirming only that testing took place); AbbVie Pre-Trial

178
    AbbVie’s claim to the remaining $140,887 also fails as speculative. Even Dr. Meyer admitted
that she could not identify what the cost corresponds to. See Meyer Report at 0110 (admitting that
some or all of the figure may represent an allocation of overhead at AbbVie’s testing facility).

    Per AbbVie, a chargeback is “[a] cost issued by a wholesaler to AbbVie, which AbbVie pays,

acquisition cost] and the contracted price paid to the wholesaler by the end customer.” AbbVie

or two,185 continued to roll in. This artificially deflated the 2020 non-FAMP.186 One

year later, Lupron sales had begun to recover, causing a pronounced rise between

the 2020 and 2021 non-FAMP.187 This triggered discounts under the VHA, which

caused the Federal Ceiling Price, which is calculated as a 24% discount to a drug’s

previous year’s non-FAMP,188 to turn negative in 2022,189 allowing federal agencies

to purchase certain Lupron formulations at a price of one penny per syringe. 190 Dr.

Meyer calculates the economic loss due to these additional discounts by assuming

that the discounts AbbVie would have provided to these agencies, but for the

shortage-induced pricing, would have been the same as they were in 2020.191

       Though AbbVie explicitly raises this category of damages in both its pre- and

post-trial briefing,192 Takeda’s declines to address the issue directly,193 waiving the

argument.194 Thus, the only question is whether AbbVie has carried its burden with

regard to the penalty pricing damages. I find that it has, and that Dr. Meyer’s

damages.195

       D. Causation, Mitigation

               1. Causation

       It is indisputable that AbbVie suffered lasting damages as a result of the

Lupron shortage.        The impact of the shortage is perhaps best demonstrated

graphically:

                 Figure 1: U.S. ADT Market Share, Q1 2017 to Q1 2022196




195
    I find that AbbVie has proven both the fact of damages, as well as causation, by a preponderance
of the evidence.

                                                37
The shortage sent Lupron URO’s market share crashing down, with limited recovery

even a year later. As discussed above, AbbVie also suffered damages in the PED

and GYN markets.

       While Takeda acknowledges that AbbVie suffered some damages as a result

of the shortage,197 it argues that AbbVie simply assumes causation and thus fails to

“sufficiently isolate damages caused by the breach alone[.]”198 Per Takeda, this

alleged failure to show causation means that “‘no damages may be awarded.’”199

Because Takeda’s position on causation largely repackages arguments that I

addressed in Section II.C,200 I limit my analysis here to the non-duplicative

contentions.

       Takeda’s principal argument on causation is that AbbVie failed to account for

customers that, for reasons unrelated to the shortage, switched away from Lupron

during the damages period.201 As evidence, Takeda points to a survey in which its

economic expert reached out to the “physicians, pharmacists, practice managers, and

purchasing/procurement managers, who were affiliated or employed with an

institution” that AbbVie reported had stopped or decreased Lupron purchases

because of the shortage.202 Takeda pays particular attention to three former Lupron

customers—Mayo Clinic, Huntington Internal Medicine Group, and Urologic

Specialists of Oklahoma—that reported in the survey that they switched away for

reasons unrelated to the shortage.203 Per Takeda, the inclusion of these accounts in

the damages calculation “is unjustified, and evidence of a much broader error.”204

       Takeda, I think, fundamentally misunderstands the underlying damages

methodology used by both parties’ experts. In estimating damages for the URO

segment,205 both experts calculate a baseline market share against which shortage-

induced damages can be assessed.206 Changes to Lupron’s market share in the form

of routine losses and gains of customer accounts are “baked in” to this baseline. For

example, the loss of a customer to Eligard in May 2019 would be reflected in a drop

in Lupron’s market share from that month onward. Similarly, the gain of a customer

in July 2019 would bring with it a corresponding increase in market share, all else

equal. A pervasive pattern of customer losses pre-shortage would present itself as a

                                             39
downward slope in the baseline.207 Thus, absent evidence of confounding trends not

accounted for in the model, AbbVie’s damages methodology adequately

demonstrates causation by isolating the impact of the shortage from the but-for world

conditions incorporated in the market share baseline.

       In order to show a lack of causation, Takeda would need to point to more than

anecdotal evidence that specific switches were unrelated to the shortage. Instead,

Takeda must show a pattern of post-shortage customer behavior that deviates from

the pre-shortage behavior reflected in the damages model. For example, if, from

October 2021 onward, price-based switches to Eligard accelerated vis-à-vis the

baseline for reasons unrelated to the shortage, AbbVie would not be entitled to

damages for the loss of sales associated with that new trend. Takeda’s survey-based

causation argument reflects no such trend or pattern absent from the baseline.

Instead, it represents an attempt to argue via anecdote what Takeda has failed to

prove with data.

               2. Mitigation

       Takeda argues that AbbVie’s damages must be reduced because of its failure

to mitigate the damages resulting from Takeda’s breach.208 Specifically, Takeda




207
    In fact, this is precisely the adjustment that Takeda’s economic expert advocated for in response
to alleged price competition from Eligard. Malkiewicz Report at 0047–49. I rejected that
adjustment as based on stale data. See Section II.C.2.

contends that AbbVie knew of the breach in May 2019 and could have mitigated

starting then by (1) exercising its contractual rights to audit Takeda’s manufacturing

process more closely, (2) stockpiling additional Lupron, and (3) not implementing a

plan—“Operation Phoenix”209—that purportedly shifted Lupron supply towards

lower-profit sales channels.210 Even assuming that Takeda is correct as to AbbVie’s

knowledge of the breach in May 2019, Takeda’s arguments fail.

       Takeda argues that, because AbbVie had joint responsibility for current good

manufacturing practices violations at the Hikari plant, it could have exercised its

rights to “audit Takeda every two years, inspect documents, attend regulatory

inspections, and put a ‘person in the plant’ to inspect manufacturing.”211 Takeda’s

implied argument, as I understand it, is that it would have complied with these steps,

potentially averting or mitigating the supply shortage.              This argument strains

credulity, given that, in June 2019, as Takeda’s manufacturing woes became visible,

Takeda repeatedly downplayed the concerns of AbbVie’s auditor and denied

requests for further information.212 I therefore find that the record does not support

Takeda’s argument that AbbVie could have mitigated via the exercise of its

contractual rights.

       Takeda next argues that, had AbbVie stockpiled Lupron starting in May 2019,

“[e]very week of additional inventory AbbVie had on-hand would have reduced the

shortage by a week.”213 In addition to benefiting from a healthy dose of hindsight,

this argument ignores the reality that Takeda has no “best efforts” duty when it

comes to fulfilling orders exceeding 120% of previously projected requirements.214

Therefore, even if AbbVie had attempted to increase its orders in the hopes of

creating a stockpile, Takeda would have had little obligation to cooperate.215

Finally, Takeda also turns a blind eye to the fact that AbbVie submits its firm orders

to Takeda five months in advance,216 which means that hypothetical stockpile

shipments ordered in May 2019 would have run into the FDA-ordered hold on

Lupron shipments.217

       Finally, Takeda argues that AbbVie’s shortage-response plan, Operation

Phoenix, “drove volume away” from profitable sales channels in order to preserve

supply in other, less profitable, channels.218         This argument attacks AbbVie’s

mitigation attempts merely because they do not comport with what Takeda now

believes would have been the best course of action. Other than labelling Operation

legal and factual support.

       E. Pre- and Post-Judgment Interest

       In its post-trial briefing, AbbVie makes an unopposed request for pre- and

post-judgment interest.220 I find that an award of interest at the legal rate is

appropriate given the facts of the case and that such an award is consistent with

Delaware caselaw.221

                                  III. CONCLUSION

       I find that AbbVie’s damages methodology is reliable and appropriate, subject

to the foregoing adjustments. I instruct the parties to submit an adjusted damages

calculation consistent with this decision.

       To the extent the foregoing requires an order to take effect, IT IS SO

ORDERED.
