TIME TO CLINICAL PoC

We have initiated programs in three primary arr

vivo programs targeting the liver and (iii) additional in vivo programs targeting other organ systems such as muscle and lung. By
focusing our most advanced programs in ex vivo applications we believe we can mitigate technical and clinical risk, while also
developing in vivo programs in parallel to fully realize the potential of our platform.

We intend to develop CRISPR/Cas9-based therapeutics both independently and in collaboration with current and potential
corporate partners. We have establia

Overview

Beta-thalassemia is a blood disorder that is associated with a reducdd tion in the production of hemoglobin. This disease is caused
by mutations that give rise to the insufficient expression of the beta globin protein, which can lead to symptoms related to not only the
lack of hemoglobin, but also as result of the buildup of unpaired alpha globin proteins in red blood cells. The severity of symptmm oms
associated with beta-thalassemia varies depending on the levels of functional beta globin present in the blood cells. In the most severe
cases, described as beta-thalassemia major, func

The most common treatment for beta-thalassemia is chronic blood transfusions. Patients typically receive transfusff

ions every two
to four weeks and chronic administration of blood often leads to elevated levels of iron in the body and can cause organ damage over a
relatively short period of time. Patients are often given iron chelators, or medicines to reduce iron levels in the blood, which are
associated with their own significant toxicities. Low adherence to this burdensome regime often results in death by 30 years of age for

Some patients with beta-thalassemia or SCD have elevated levels of HbF that persist into adulthood, a condition known as hereditary

This protective HPFH condition has been shown to result from specific changes to the DNA in the cell, either in the region of the

Ability of different gene targets to drive HbF production

To date, we have identified guide RNAs that perform the desired gene edits with very high efficiency, result in high levels of
HbF production in cells and show no detectable evidence of off-target effects. As we continue to advance our hemoglobinopathies
programs to the clinic, we are in the process of evaluating the ability of edited hematopoietic stem cells to engraft and persist in mice.
Our initial engraftment studtt
ies show that the edited cells retain their ability to engraft and repopulate in immuno-compromised mice.
Additionally, a subset analysis of the edited hematopoietic stem cells shows that all subsets of stem cells including the long-term

Hurlerll Syndrome

Hurler syndrome is a type of mucopolysaccharide disease caused by a defective IDUA gene. The IDUA gene is responsible for

encoding alpha-L-iduronidase, an enzyme that breaks down large molecules called glycosaminoglycans, or GAGs, in the lysosomes of
cells. A defective IDUA gene results in a lack of alpha-L-iduroindase which leads to an accumulation of GAGs and results in cellular
dysfunction and severe clinical abnormalities. Patients with Hurler syndrome have a broad spectrum of clinical problems including

Glycogen Storagea Disease IaII

Overview

GSDIa, also known as Von Gierke disease, is an autosomal recessive inborn err

sm caused by a mutation
in the G6PC gene, which encodes the glucose-6-phosphatase protein, or G6Pase. In patients with GSDIa, the lack of G6Pase prevents
the release of glucose from the liver, resulting in accumulation of a large chain form of glucose known as glycogen. The inability of
patients with GSDIa to regulate glucose levels leads to hypoglycemia, or low blood glucose, and high levels of lactic acid when
patients are not eating, requiring patients to adhere to burdensome dietaryrr
regimes. GSDIa patients also face long-term risks such as
growth delay, neuropathy and kidney stones. Additionally, due to the accumulation of glycogen in the liver, 70% to 80% of patients
over 25 years of age will develop hepatocellular adenomas, a type of non-cancerous growth in the liver, of which approximately 10%
will progress to hepatocellular carcinoma, a potentially fatal liver cancer. There are approximately 1,000 new cases of GSDIa per year
worldwide.

We are developing a CRISPR/Cas9 product candidate to correct the mutation in GSDIa patients. Animal model experiments

have demonstrated that the addition of functional copies of the G6PC gene is capable of correcting the defici
ency of G6Pase protein in
GSDIa and that as little as 3% of normal levels of G6Pase can restore the equilibrium of glucose and glycogen in the bloodstream and
liver. Our approach is to correct the G6PC gene directly in its native location. We believe this direct gene correction will result in
appropriate expression of the G6Pase protein. Other methods rely on adding copies of the gene through viral delivery methods, which
we believe may lead to overexpression of the G6Pase protein and ineffecff

In December 2015, we entered into a Joint Venture Agreement, or the JV Agreement, with Bayer HealthCare LLC, or Bayer

linked diseases, including blood disorders, blindness and heart disease. At the closing of the transactions contemplated by the JV

each have exclusive rights to specified disease indications, the CRISPR Field and Bayer Field, respectively, as discussed below.

In November of 2016, Casebia appointed James Burnsrr

majority vote, with each member having one vote. Certain matters require the consent of Bayer HealthCare and us.

the two parties were not directed to the same patentable invention in accordance with the PTAB’s two-way test forff
interferences. In particular, the Junior Party’s claims in the interference were all limited to uses in eukaryorr
tic cells, while the Senior
Party’s claims in the interference were not limited to uses in eukaryotic cells but included uses in all settings. Either party can appeal
an adverse decision to the U.S. Court of Appeals for the Federal Circuit. In parallel, either party can also pursue existing or new patent
applications in the U.S. and elsewhere. Going forward, either party as well as other parties could seek a new interference related to the
uses of the technology in eukaryotic cells or other aspects of the technology, and any existing or new patents could be the subjb ect of
other challenges to their validity of enforcff

to practice our core gene editing technology. If there is a second interference, either party could again appeal an adverse decision to
the U.S. Court of Appeals for the Federal Circuit. In any case, it may be years before there is a final determination on priority. For
example, Toolgen Inc., or Toolgen, filed Suggestions of Interference in the USPTO on April 13, 2015 and December 3, 2015,
suggesting that they believe some of the claims in pending U.S. applications owned by Toolgen (U.S. Serial No. 14/685,568 and U.S.

Clinical trials involve the administration of the investigational productdd

are conducdd ted under studtt y protocols detailing, among other things, the objb ectives of the stutt dy, inclusion and exclusion criteria, the
parameters to be used in monitoring safety, and the effectiveness criteria to be evaluated. A protocol for each clinical trial and
subsequent protocol amendments must be submitted to the FDA as part of the IND.

Pediatric exclusivity is another type of non-patent marketing exclusivity in the United States and, if granted, provides for the
attachment of an additional six months of marketing protection to the term of any existing regulatory exclusivity, including the non-
patent and orphan exclusivity. This six-month exclusivity may be granted if a BLA sponsor submits pediatric data that fairly respond
to a written request from the FDA for such data. The data do not need to show the product to be effective in the pediatric population
studied; rather, if the clinical trial is deemed to fairly respond to the FDA’s request, the additional protection is granted. If reports of
requested pediatric studies are submitted to and accepted by the FDA within the statutory time limits, whatever statutory or regulatory
periods of exclusivity or patent protection cover the producdd t are extended by six months. This is not a patent term extension, but it

The Foreseeable Future.

We have funded our operations to date through proceeds from our initial public offering, or the IPO, and concurrent private

placement of our common shares, private placements of our preferredrr
Casebia Therapeutics, LLC pursuant to our joint venture with Bayer HealthCare LLC, or Bayer Healthcare, and our collabor
Vertex Pharmaceuticals, Incorporated, or Vertex. Since inception, we have incurred significant operating losses. Our net loss was
$23.2 million, $25.8 million, and $6.8 million for the years ended December 31, 2016, 2015 and 2014, respectively. As of
December 31, 2016 and 2015, we had an accumulated defici

CRISPR/Cas9 gene editing technology is relatively new and no products based on CRISPR/Cas9 or other similar gene editing
technologies have been approved in the United States or the European Union and only a limited number of clinical trials of products
based on gene editing technologies have been commenced. As such it is difficult to accurately predict the developmental challenges
we may incur for our product candidates as they proceed through productdd
discovery or identification, preclinical studies and clinical
trials. In addition, because our programs are all in the research or preclinical stage, we have not yet been abla e to assess safetyff
humans, and there may be long-term effects from treatment with any product candidates that we develop that we cannot predict at this
time. Any product candidates we may develop will act at the level of DNA, and, because animal DNA differs from human DNA,
testing of our producdd t candidates in animal models may not be predictive of the results we observe in human clinical trials of our

Our ability to commercialize any products successfully also will depend in part on the extent to which reimbursement for these
products and related treatments will be available from government health administration authorities, private health insurers, and other
organizations. Government authorities and third-party payors, such as private health insurers and health maintenance organizations,
decide which medications they will pay for and establish reimbursement levels. A primary t
nd
elsewhere is cost containment. Government authorities and third-party payors have attempted to control costs by limiting coverage and
the amount of reimbursement for particular medications. Increasingly, third-party payors are requiring that drug companies provide
them with predetermined discounts from list prices and are challenging the prices charged forff medical products. We cannot be sure
that reimbursement will be available for any producdd t that we commercialize and, if reimbursement is available, the level of
reimbursement. Reimbursement may impact the demand for,
or the price of, any product candidate forff which we obtain marketing
approval. If reimbursement is not availabla e or is available only to limited levels, we may not be able to successfully commercialize
any producdd t candidate for which we obtain marketing approval.

As of December 31, 2016, we had 93 full-time employees and we expect to increase our number of employees and the
scope of our operations in 2017 and beyond as we conduct activities as a public company and seek to advance
development and if successful, commercialization, of our product candidates. To manage our anticipated development and
expansion, we must continue to implement and improve our managerial, operational and financial systems, expand our
facilities and continue to recruit and train additional qualified personnel. Also, our management may need to divert a
disproportionate amount of its attention away from its day-to-day activities and devote a substantial amount of time to
managing these expansion activities. Due to our limited resources, we may not be able to effeff ctively manage the
expansion of our operations or recruit
infrasff
among remaining employees. The physical expansion of our operations may lead to significff ant costs and may divert
financial resources from other projects, such as the development of our product candidates. If our management is unablea
to effectively manage our expected expansion, our expenses may increase more than expected, our ability to generate or

In the United States, each co-owner has the freedom to license and exploit the technology. As a result, we do not have exclusive
access to any intellectual property rights that Dr. Charpentier co-owns with another entity, such as California and Vienna. Our license

tier is therefore non-exclusive with respect to such co-owned rights. Furthermore, in the United States each co-owner
is required to be joined as a party to any claim or action we may wish to bring to enforce those patent rights. Moreover, in the United
States, non-exclusive licenses have no standing to bring a patent infringement action before a court. Therefore, for the patents owned

eneral,

As is the case with other biopharmaceutical companies, our success is heavily dependent on intellectuatt

l property, particularly
patents. Obtaining and enforcing patents in the biopharmaceutical industry involves both technological and legal complexity and is
therefore costly, time consuming and inherently uncertain. Recent patent reform legislation in the United States and other countries,
including the Leahy-Smith America Invents Act, or Leahy-Smith Act, signed into law on September 16, 2011, could increase those
uncertainties and costs. The Leahy-Smith Act includes a number of significant changes to U.S. patent law. These include provisions
that affect the way patent applications are prosecuted, redefine prior art and provide more efficff
ient and cost-effective avenues for
competitors to challenge the validity of patents. In addition, the Leahy-Smith Act has transformff
ed the U.S. patent system into a “first
ve on March 16, 2013. Accordingly, it is not yet clear what,
to file” system. The first-to-fileff
if any, impact the Leahy-Smith Act will have on the operation of our business. However, the Leahy-Smith Act and its implementation
could make it more difficff
ult to obtain patent protection for our inventions and increase the uncertainties and costs surrounding the
prosecution of our patent applications and the enforcement or defense of our issued patents, all of which could harm our business,
results of operations and financial condition.

an inventive concept aboa ve and beyond an isolated natural product, a court may decide the claims are invalid under Myriad.dd
Additionally, there have been recent proposals for additional changes to the patent laws of the United States and other countries that, if
adopted, could impact our ability to obtain patent protection for our proprietary technology or our ability to enforce our proprietary
technology. Depending on future actions by the U.S. Congress, the U.S. courts, the USPTO and the relevant law-making bodies in

We are a Swiss corporation organized under the laws of Switzerland and our registered offiff ce and domicile is located in Basel,

Switzerland. Moreover, certain of our directors and executive officers and a number of directors of each of our subsidiaries are not
residents of the United States, and all or a substantial portion of the assets of such persons are located outside the United States. As a
result, it may not be possible for investors to effect service of process within the United States upon our directors and officers residing
as our agent to effect service of process
outside the United States. Additionally, even though we have appo
upon us in the United States, investors may be unablea
to enforce against us or our directors and officers residing outside the United
States judgments obtained in U.S. courts, including judgments in actions predicated upon the civil liabia lity provisions of the federal
securities laws of the United States. We have been advised by our Swiss counsel that there is doubt as to the enforceability in

predicated upouu n the federal and state securities laws of the United States. Original actions against persons in Switzerland based solely
upon the U.S. federal or state securities laws are governed, among other things, by the principles set forth in the Swiss Federal Act on
Private International Law. This statute provides that the application of provisions of non-Swiss law by the courts in Switzerlandaa

Switzerland and the United States do not have a treaty providing for reciprocal recognition and enforcement of judgments in

civil and commercial matters. The recognition and enforcement of a judgment of the courts of the United States in Switzerland is
governed by the principles set forth in the Swiss Federal Act on Private International Law. This statute provides in principle that a

Use of Proceeds from Registered Securities

On October 24, 2016, we closed the sale of 4,429,311 of our common shares in our initial public offering, or the IPO, inclusive

of 429,311 common shares sold by us pursuant to the partial exercise of an overallotment option granted to the underwriters in
connection with the offering, at a price to the public of $14.00 per share. The aggregate net proceeds received by us from the offering
ing expenses payable by us. None of these
were $53.7 million, after deducting underwriting discounts and commissions and other offer
expenses consisted of payments made by us to directors, officers or persons owning 10% or more of our common shares or to their
associates, or to our affiliates. Concurrent with the IPO, we issued and sold 2,500,000 common shares to Bayer BV, at the IPO price
$14.00 per share, or (the “Concurrent Private Placement”), resulting in aggregate net proceeds of $35.0 million in accordance with the
terms of our subscription agreement with Bayer BV.

and sale of the shares in the IPO was registered under the Securities Act pursuant to registration statements on

Form S-1 (File No. 333-213577), which was filed with the SEC, on September 9, 2016 and amended subsequently and declared
effective on October 18, 2016. Citigroup Guu
lobal Markets Inc., Piper Jaffray & Co. and Barclays Capital Inc. acted as joint book-
running managers of the offering.

There has been no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with

the SEC on October 19, 2016 pursuant to Rule 424. We invested the unused proceeds from the offering in cash equivalents in
accordance with our investment policy.

Research and development expenses increased by $11.1 million to $12.6 million for the year ended December 31, 2015, from

$1.5 million for the year ended December

an increase in employee costs of $4.8 million associated with salaries, benefits and equity-based compensation expenses from hiring
additional personnel, an increase in professional service expense of $2.0 million, an increase in facilities expense of $2.3 million,
principally associated with the establishment in February 2015 of our research and development center in Cambridge, Massachusetts,

increase in employee costs of $1.9 million associated with salaries, benefits and equity-based compensation expenses from hiring
additional senior personnel, increased consulting and professional fees of $3.2 million, including directors’ fees, audit and accounting

Critical Accounting Policies and Significant Judgments and Estimates

important to understanding our historical and futff urtt e performance. We referff
generally require us to make judgments and estimates about matters that are uncertain at the time we make the estimate, and different
estimates—which also would have been reasonable—could have been used. On an ongoing basis, we evaluate our estimates and
judgments, including those described in greater detail below. We base our estimates on historical experience and other market-specific
or other relevant assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making

While our significant accounting policies are described in more detail in the notes to our financial statements included elsewhere

in this prospectus, we believe that the following accounting policies are the most critical to aid you in fully understanding and
evaluating our financial condition and results of operations.

Revenue

We recognize revenue for each unit of accounting when all of the following criteria are met: (i) persuasive evidence of an

arrangement exists, (ii) delivery has occurred or services have been rendered, (iii) the seller’s price to the buyer is fixed or
determinable and (iv) collectability is reasonablya

whether such deliverables are separable from the other aspects of the contractual relationship. Deliverablea

includes a general right of return with respect to the delivered item, delivery or performance of the undelivered item is considered

The consideration received under an arrangement that is fixed or determinabla e is then allocated among the separate units of

accounting based on the relative selling prices of the separate units of accounting. We determine the selling price of a unit of
accounting within each arrangement using (i) vendor-specific objeb ctive evidence of selling price, if available; (ii) third-party evidence
of selling price if vendor-specific objective evidence is not available; or (iii) best estimate of selling price, if neither vendor-specificff
objective evidence nor third-party evidence is available. Determining the best estimate of selling price for a unit of accounting requires

recognize revenue from the combined unit of accounting over the contractual or estimated performance period forff

We evaluate whether each milestone is substantive and at risk to both parties on the basis of the contingent naturtt e of the
milestone. This evaluation includes an assessment of whether: (i) the consideration is commensurate with either our performance to
achieve the milestone or the enhancement of the value of the delivered item as a result of a specific outcome resulting from our
performance to achieve the milestone, (ii) the consideration relates solely to past performance and (iii) the consideration is reasonable
relative to all of the deliverables and payment terms within the arrangement. We evaluate factors such as the scientific, clinical,
regulatory, commercial and other risks that must be overcome to achieve the particular milestone and the level of effort and
investment required to achieve the particular milestone in making this assessment. There is considerable judgment involved in
determining whether a milestone satisfies all of the criteria required to conclude that a milestone is subsu tantive. We will recognize
revenue in its entirety upon successful accomplishment of any substantive milestones, assuming all other revenue recognition criteria

Our primary performance obligations under this collaboration consist of research and development services. In certain instances, the
timing of satisfying these obligations can be diffiff cult to estimate. Accordingly, our estimates may change in the future. Such changes

718 requires all equity-based compensation awards to employees and non-employee directors, including grants of restricted shares and
stock options, to be recognized as expense in the statements of operations based on their grant date fair values. We estimate the fair

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders
CRISPR Therapeut

ics AG

aa

We have audited the accompanying consolidated balance sheets of CRISPR Therapeutics AG (the “Company”) as of December 31,
red shares
2016 and 2015, and the related consolidated statements of operations and comprehensive loss, redeemable convertible preferff
and shareholders' (deficit) equity, and cash flows
for each of the three years in the period ended December 31, 2016. These financial
statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial
statements based on our audits.

ff

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those
standards require that we plan and perforff m the audit to obtain reasonabla e assurance about whether the financial statements are free of
material misstatement. We were not engaged to perform an audit of the Company’s internal
control over financial reporting. Our
designing audit procedures that are appropriate
audits included consideration of internal control over financial reporting as a basis forff
in the circumstances, but not for the purporr
tiveness of the Company’s internal control over
se of expressing an opinion on the effff ecff
financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our
opinion.

rr

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of
CRISPR Therapeutics AG at December 31, 2016 and 2015, and the consolidated results of its operations and its cash flows for each of
the three years in the period ended December 31, 2016, in conformity with U.S. generally accepted accounting principles.

The preparation of finff ancial statements in conformi

affect the amounts reported in the financial statements and accompanying notes. On an ongoing basis, the Company’s management
evaluates its estimates, which include, but are not limited to, equity-based compensation expense, revenue recognition, equity method
investments, and reported amounts of expenses during the reported period. Significant estimates in these consolidated finaff
statements have been made in connection with the calculation of revenues, research and development expenses, valuation of equitytt
method of investment, equity-based compensation expense, fair value of Common Shares, fair value of intangible assets, and the
provision for or benefit from income taxes. The Company bases its estimates on historical experience and other market-specificff or

in the circumstances.

The accounting standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered
, that may be used to measure fair value, which are the following:

observable and the last unobservablea

Level 1 — Quoted prices in active markets that are accessible at the market date for identical unrestricted assets or liabilities.

Level 2 — Inputs other than Level 1 that are observablea

Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the

assets or liaba ilities.

To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the

determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining
fair value is greatest forff
instruments categorized in Level 3. A finff ancial instrument’s level within the fair value hierarchy is based on
the lowest level of any input that is significant to the fair value measurement.

The Company evaluates long-lived assets for potential impairment when events or changes in circumstances indicate the

carrying value of the assets may not be recoverable. Recoverability is measured by comparing the book value of the assets to the
expected futff urtt e net undiscounted cash flows that the assets are expected to generate. If such assets are considered to be impaired, the
impairment to be recognized is measured by the amount by which the book value of the assets exceed their fair value. The Company
has not recognized any impairment losses in the years ended December 31, 2016, 2015, and 2014.

Revenue Recognition

To date, the Company’s only source of revenue has been the collaboration and license agreement with Vertex as well as
research and development services provided to Casebia under the joint venture with Bayer HealthCare LLC (“Bayer”) (see Note 9).

The Company recognizes revenue in accordance with ASC Topic 605, Revenue Recognition (“ASC 605”). Accordingly,

revenue is recognized for each unit of accounting when all of the following criteria are met:

•

The Company evaluates multiple-element arrangements based on the guidance in FASB ASC Topic 605-25, Revenue

multiple-element arrangements to determine (i) the deliverables included in the arrangement and (ii) whether the individual
deliverables represent separate units of accounting or whether they must be accounted forff
as a combined unit of accounting. When
deliverables are separable, consideration received is allocated to the separate units of accounting based on the relative selling price
method and the appropriate revenue recognition principles are applied to each unit. When the Company determines that an
arrangement should be accounted forff
performance obligations will be performed and revenue will be recognized. This evaluation requires the Company to make judgments

accounting based on the relative selling prices of the separate units of accounting. The Company determines the selling price of a unit
of accounting within each arrangement following the hierarchy of evidence prescribed by ASC 605-25. Accordingly, the Company
determines the estimated selling price forff

selling price (“BESP”) if neither VSOE nor TPE is available. The Company typically uses BESP to estimate the selling price as it
generally does not have VSOE or TPE of selling price for its units of accounting. Determining the BESP for a unit of accounting
requires significant judgment. In developing the BESP forff

exist, then the Company recognizes revenue under the arrangement on a straight-line basis over the period the Company is expected to
complete its performance obligations. Conversely, if the pattern of perforff mance over which the service is provided to the customer can
be determined and objeb ctively measurabla e performance measures exist, then the Company recognizes revenue under the arrangement
using the proportional performance method. Revenue recognized is limited to the lesser of the cumulative amount of payments

The Company accounts for stock options issued to non-employees under FASB ASC Topic 505-50, Equity Btt

tt o
Non-EmpEE loyeo es (“ASC 505-50”). As such, the value of such options is periodically remeasured and income or expense is recognized
over their vesting terms. Compensation cost related to awards with service-based vesting schedules is recognized using the straight-
line method.

ased Payments t

The Black-Scholes option pricing model requires the input of certain subjeu

ctive assumptions, including (i) the expected share
price volatility, (ii) the calculation of expected term of the award, (iii) the risk-freff e interest rate and (iv) the expected dividend yield.
Due to the lack of a public market for the trading of the Company’s Common Shares prior to its IPO and a lack of company-specififf c
historical and implied volatility data, the Company has based its estimate of expected volatility on the historical volatility of a group of
similar companies that are publicly traded. The historical volatility is calculated based on a period of time commensurate with the
expected term assumption. The group ouu
f representative companies have characteristics similar to the Company, including stage of
product development and focus on the life science industry. The Company uses the simplifiedff method, which is the average of the
options granted to employees as it does not have

final vesting tranche date and the contractuatt

employees, the Company utilizes the contractuatt
l term of the arrangement as the basis for the expected term assumption. The risk-free
interest rate is based on a treasury instrument whose term is consistent with the expected term of the stock options. The Company uses
an assumed dividend yield of zero as the Company has never paid dividends and has no current plans to pay any dividends on its
Common Shares.

The Company expenses the fair value of its equity-based compensation awards granted to employees on a straight-line basis
over the associated service period, which is generally the period in which the related services are received. The Company measures
equity-based compensation awards granted to non-employees at fair value as the awards vest and recognizes the resulting value as
compensation expense at each financial reporting period.

The Company records the expense for equity-based compensation awards subject to performance-based milestone vesting over

the remaining service period when management determines that achievement of the milestone is probable. Management evaluates
when the achievement of a perforff mance-based milestone is probable based on the expected satisfaction of the perforff mance conditions
as of the reporting date.

Income taxes are recorded in accordance with FASB ASC Topic 740, Income Taxes (“ASC 740”), which provides for deferred

taxes using an asset and liability approach. Under this method, deferred tax assets and liabilities are determined based on the
difference between the financial reporting and tax reporting basis of assets and liabilities and are measured using enacted tax rates and
laws that are expected to be in effect when the differences are expected to reverse. Valuation allowances are provided if, based upon
the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The

The Company evaluated the Collaboration Agreement in accordance with the provisions of ASC 605-25. The Company’s

arrangement with Vertex contains the following initial deliverables: (i) a non-exclusive research license; (ii) the option to obtain an
hemoglobinopathy or beta-
exclusive license for up to six Collaboration Targets; (iii) the option to obtain a co-exclusive license forff
globin targets (which would be included within the maximum number of the aforementioned six collabor
ation targets); (iv) R&D
Services; and (v) JRC participation.

Management considered whether any of these deliverables could be considered separate units of accounting. Regarding the non-

exclusive research license, the Company concluded that it does not have stand-alone value separate from the option to exercise the
exclusive or co-exclusive license since Vertex would not benefitff

license to commercialize the results of that research. As a result, the Company concluded that the research license should be combined
with those options.

Regarding the R&D Services, the Company concluded that there are other vendors in the market that could performff

Regarding the JRC obligations, the Company concluded that the JRC obligations deliverable has standalone value from the

option to license because the services could be perforff med by an outside party. As such the Company concluded the JRC obligations
represent a separate unit of accounting.

As a result, management concluded that there are four

units of accounting at the inception of the agreement: (i) a combined unit

The Company has determined that neither VSOE of selling price nor TPE of selling price is available for any of the units of

The amount allocated to R&D Services will be recognized as the R&D Services are performed. The Company will recognize as
license revenue an equal amount of the total arrangement consideration allocated to the exclusive licenses as each individual license is
delivered to Vertex uponuu
Vertex’s exercise of its options to such licenses. The Company will recognize $8.4 million as license revenue
when the Co-exclusive License is delivered to Vertex upon Vertex’s exercise of its options to such license.

The Company has evaluated all of the milestones that may be received in connection with the Collaboration Agreement. In

evaluating if a milestone is subsu tantive, the Company assesses whether: (i) the consideration is commensurate with either the
Company’s performance to achieve the milestone or the enhancement of the value of the delivered item(s) as a result of a specific
outcome resulting from the Company’s performance to achieve the milestone, (ii) the consideration relates solely to past perforff mance,

After Vertex has exercised an Exclusive License option, Vertex will be solely responsible for all research, development,

manufacturi
process is limited to observer status, management determined that milestones are not considered subsu tantive because they do not relate
solely to the past perforff mance of the Company. Upon the achievement of a milestone, management will evaluate whether the
triggering event occurs during or after the research term. If the triggering event occurs during the research term, management has
elected to treat the milestone similar to an up-front payment. In these cases, if and when any of these milestones are received, the
amount will be included in the overall arrangement consideration and allocated to the remaining identified deliverables. To the extent
all deliverables have been satisfied, any additional consideration allocated to them could be immediately recognized. If the triggering
event occurs after the research term, the Company will recognize the associated revenue in the period in which the event occurs. The
Company will recognize royalty revenue in the period of sale of the related product(s), based on the underlying contract terms,
provided that the reported sales are reliably measurable and the Company has no remaining perforff mance obligations, assuming all
other revenue recognition criteria are met.

In connection with the issuance of the Series A-2 Preferred Shares, the Series A-1 Tranche Rights were terminated without

The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally

accepted in the United States of America (“GAAP”), and include the accounts of Casebia and its subsidiary. All intercompany
accounts and transactions have been eliminated. Any reference in these notes to appa

ff

The preparation of financial statements in conformff

ity with GAAP requires management to make estimates and assumptions that

affect the amounts reported in the financial statements and accompanying notes. On an ongoing basis, Casebia’s management
evaluates its estimates, which include, but are not limited to, equity-based compensation expense and reported amounts of expenses
during the reporting period. In addition, significant estimates in these consolidated financial statements have been made in connection
with the calculation of the value of contributed technology and research and development expenses. Casebia bases its estimates on
historical experience and other market-specific or other relevant assumptions that it believes to be reasonabla e under the circumstances.
Actual results may differff

from those estimates or assumptions.

free or escalating rent payment provisions. Casebia recognizes rent expense under such leases on a straight-line basis over the term of
the lease with the difference between the expense and the payments recorded as deferred rent on the consolidated balance sheet.
Amounts received from lessors are accounted for as lease incentives, which are amortized as a reduction of rent expense over the term
of the lease. Lease renewal periods are considered on a lease-by-lease basis in determining the lease term.

The Revenue ASUs provide an accounting standard for a single comprehensive model for use in accounting for revenue arising

from contracts with customers and supersedes most current revenue recognition guidance. The accounting standard is effective for
interim and annual periods beginning after December 15, 2017, with an option to early adopt for interim and annual periods beginning
after December 15, 2016. The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (the
full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of
initial application (the modifieff d retrospective method). Casebia currently anticipates adoption of the new standard effeff ctive January 1,

Report of the statutory auditor on the consolidated financial statements

As statutory auditor, we have audited the accompanying consolidated financial statements ofo
CRISPR Therapeutics AG (F-2 through F-34), which comprise the consolidated balance
sheets, the consolidated statements of operations and comprehensive loss, consolidated
statements of convertible preferred shares and shareholders’ equity (deficit), consolidated
statements of cash flows, and notes to the consolidated financial statements, for the year
ended 31 December 2016.

responsibility

Board of Directors’rr
The Board of Directors is responsible for the preparation of the consolidated financial
statements in accordance with US Generally Accepted Accounting Principles (US GAAP) and
the requirements of Swiss law. This responsibility includes designing, implementing and
maintaining an internal control system relevant to the preparation of consolidated financial
statements that are free from material misstatement, whether due to fraud or error. The
Board of Directors is further responsible for selecting and applying appropriate accounting
policies and making accounting estimates that are reasonable in the circumstances.

Auditor’s responsibility
Our responsibility is to express an opinion on these consolidated financial statements based
on our audit. We conducted our audit in accordance with Swiss law, Swiss Auditing
Standards, and the standards of the Public Company Accounting Oversight Board (United
States). Those standards require that we plan and perform the audit to obtain reasonable
assurance whether the consolidated financial statements are free from material
misstatement.

rming procedures to obtain audit evidence about the amounts and

An audit involves perforr
disclosures in the consolidated financial statements. The procedures selected depend on the
auditor’s judgment, including the assessment of the risks of material misstatement of the
consolidated financial statements, whether due to fraud or error. In making those risk
assessments, the auditor considers the internal control system relevant to the entity’s
preparation of the consolidated financial statements in order to design audit procedures that
are appropriate in the circumstances, but not for the purpose of expressing an opinion on the
effeff ctiveness of the entity’s internal control system. An audit also includes evaluating the
appropriateness of the accounting policies used and the reasonableness of accounting
estimates made, as well as evaluating the overall presentation of the consolidated financial
statements. We believe that the audit evidence we have obtained is sufficient and appropriate
to provide a basis for our audit opinion.

Opinion
In our opinion, the consolidated financial statements for the year ended 31 December 2016
give a true and fair view of the financial position, the results of operations and the cash flows
in accordance with US Generally Accepted Accounting Principles (US GAAP) and comply
with Swiss law.

Report orr n key audit matters based on the circular 1/2015 of the Federal Audit
Oversight Authority
Key audit matters are those matters that, in our professional judgment, were of most
significance in our audit of the consolidated financial statements of the current period. These
matters were addressed in the context of our audit of the consolidated financial statements as
a whole, and in forming our opinion thereon, and we do not provide a separate opinion on
these matters. For each matter below, our description of how our audit addressed the matter
is provided in that context.

We have fulfilled the responsibilities described in the Auditor’s responsibilit
report, including in relation to these matters. Accordingly, our audit included the performance
of procedures designed to respond to our assessment of the risks of material misstatement of
the consolidated financial statements. The results of our audit procedures, including the

Revenue from R&D services under collaboration agreements

Risk

CRISPR Therapeutics AG (CRISPR) has entered into material revenue
generating collaboration agreements in 2015 (Vertex Pharmaceuticals)
and 2016 (Casebia Therapeutics LLP). These arrangements were
accounted for as multiple element arrangements and each contain
separate Research and Development (R&D) servirr ce deliverables. R&D
service revenue is recognized based on actual time incurred using a
relative selling price and recorded within Collaboration Revenue on the
Consolidated Statement of Operations.

The R&D servirr ce revenue is primarily composed of R&D services
performed by internal CRISPR R&D employees; the revenue is
calculated using projeo ct based employee timesheets. Given the manual
nature of the calculation, we identified a heightened risk related to the
opportunity of management to overstate the internally sourced R&D
service revenue, specifically through the inclusion of other employees
not providing R&D servirr ces under the collaboration agreements in the
Company’s calculation, which could result in a material revenue
misstatement.

Refer to Note 9 in the Consolidated Financial Statements for CRISPR’s
accounting policy and further details.

Our audit
response

We analyzed the relevant agreements and discussed each with
management to obtain a full understanding of CRISPR’s accounting
process for the related R&D service deliverables, and the specific
underlying terms and risks.

ts for the period selected. For the selected

For a sample of instances, we obtained confirmations directly from
CRISPR employees related to their involvement in the R&D servirr ce
revenue generating projeco
samples, we reconciled the amount per the CRISPR employee
timesheet to management’s collaboration revenue calculation. We
tested each of the key contracts whereby we agreed the identified R&D
programs and FTE rates to the related collaboration agreements, and
recalculated revenue for the year based on the relative selling price
allocated to the R&D servirr ce deliverable of the arrangement.

We assessed R&D servirr ce revenue recognized by vouching subsequent
payments made by Vertex and Casebia for amounts invoiced and
confirmed outstanding receivables as of period end. Additionally, we
analyzed the Company’s recognized collaboration revenue against
expectations based on the status of the research programs tested.

the establishment of Casebia (Joint Venture with Bayer

Risk

On December 19, 2015, CRISPR Therapeutics AG (CRISPR) entered
into an agreement to establish a joint venture (“Bayer Joint Venture”)
with Bayer Healthcare LLC (“Bayer”) to discover, develop and
commercialize new breakthrough therapeutics to cure blood disorders,
blindness, and congenital heart disease. During Q1 2016, the joint
venture was legally formed and equity was contributed by the two
parties. In addition to funding, CRISPR contributed a license of its
proprietary CRISPR-Cas9 gene-editing technology and intellectual
property for selected disease indications and Bayer contributed its
protein engineering expertise and relevant disease know-how.

The Bayer Joint Venture is accounted for under the equity method as
disclosed in the Note 9 to the Consolidated Financial Statements.

Given the multiple elements of the Bayer Joint Venture arrangement
and various forms of consideration involved and the valuation
considerations thereof, we have identified a significant risk associated
with the complexities in applying the relevant accounting guidance for
the formation of the joint venture.

Page 4

audit
response

We analyzed the various clauses within the Bayer Joint Venture
agreement. We evaluated management’s assessment of the variable
interest considerations and their judgements in determining the primaryrr
beneficiary.rr We tested management’s valuation of the fair
50% interest in the joint venture and the faiff
license contributed to the entity. We involved our internal valuation
specialists to assist in the assessment of the valuation methodology and
assumptions used in determining the fair values. We evaluated the
timing of the equity method accounting for losses in the joint venture
considering the necessary elimination of intra-entity losses until such
time that the related gain from contributing the CRISPR license is
realized by CRISPR.

Report orr n other legal requirements
We confirm that we meet the legal requirements on licensing according to the Auditor
Oversight Act (AOA) and independence (article 728 CO and article 11 AOA) and that there
are no circumstances incompatible with our independence.

In accordance with article 728a para. 1 item 3 CO and Swiss Auditing Standard 890, we
confirm that an internal control system exists, which has been designed for the preparation of
consolidated financial statements according to the instructions of the Board of Directors.

We recommend that the consolidated financial statements submitted to you be approved.

determination as to whether the tax benefit will more likely than not be realized is based uponuu
the technical merits of the tax position
as well as consideration of the available facts and circumstances. As of Decembem r 31, 2016 and 2015, the Company does not have any

$35.0 million Bayer Convertible Loan automatically converted into 2,605,330 Series B Preferred Shares at $13.43 per share. The

element arrangement and using a relative fair value allocation allocated $27.0 million of aggregate arrangement consideration to the
Bayer Convertible Loan upon issuance (See Note 9). Upon conversion, thet Companymm
accreted the Bayer Convertible Loan to its face
value of $35.0 million through a charge to interest expense of $8.0 million and converted the $35.0 million to Series B Preferred
Shares under thet

of the joint venture agreement with Bayer, the Compamm ny evaluated the Bayer Convertible Loan as part of one multiple-

conversion model.

The receipt of $35.0 million in proceeds under the Bayer Convertible Loan in exchange for equity securities, combinem

d with thet
$38.2 million in proceeds from Vertex Convertible Loan, triggered an automatic conversion provision of the Vertex Convertible Loan
Agreement. Accordingly, on January 29, 2016, the Vertex Convertible Loan, including loans from existing shareholders, plus accrued
interest also converted into 2,859,278 of Series B Preferred Shares at $13.43 per share. The Company determined the fair value of the
Vertex Convertible Loan to be $26.9 million based on the fair value of the underlying Series B Preferred Shares that were exchangaa

Summary of Agff

reement

On October 26, 2015, the Company entered into a strategic collaboration, option, and license agreement (“Collaboration
Agreement”) with Vertex, focused on the use of CRISPR’s gene editing technology, known as CRISPR/Cas9, to discover and develop
potential new treatments aimed at the underlying genetic causes of human disease. The collaboration will evaluate the use of CRISPR-
Cas9 across multiple diseases where targets have been validated through human genetics. Vertex and CRISPR will focus their initial
gene editing research on discovering treatments to address the mutations and genes known to cause and contribute
disease, beta-thal
essemia and cystic fibrosis. Vertex and CRISPR will also evaluate a specifieff d numbem r of other genetic targets as part
of the collaboration. For up to six targets, Vertex has an exclusive option to obtain: (1) an exclusive license to commercialize CRISPR
technology (“Exclusive License”) or (2) a co-exclusive license with respect to hemoglobinopathy and beta-globin targets (“Co-
exclusive License”).

Allocable arrangement consideration at inception is comprmm ised of: (i) the up-uu front payment of $75.0 million, (ii) the estimated

R&D services of $26.7 million and (iii) payments related to the estimated exercise of options on future exclusive licenses for five
targets of $50.0 million. The aggregate allocablea
arrangement consideration of $151.7 million was allocated among the separate units
of accounting using the relative selling price method as follows: (i) R&D Services: $17.8 million, (ii) non-exclusive research license,

The amount allocated to R&D Services will be recognized as the R&D Services are performed. The Company will recognize as
license revenue an equalqq
amount of the total arrangement consideration allocated to the exclusive licenses as each individual license is
delivered to Vertex upon Vertex’s exercise of its options to such licenses. The Compamm ny will recognize $8.4 million as license revenue

Preferred Shares was considered an extinguishment due to the significance of the modifications to the substantive contractual terms of
the Series A-1 Preferred Shares. Accordingly, the Company recorded a loss of $0.7 million on thet
Series A-1 Preferred Shares within
additional paid-in capital equal to the differen
carrying amount of the Series A-1 Preferred Shares of $0.4 million upon extinguishment. The loss on extinguishment is reflected in

meeting certain milestones. As of Decemberm 31, 2015, none of the milestones had occurred and the Compamm ny had an outstanding
subsu cription receivable of $22.8 million related to the Series A-3 Preferred Shares. In connection with the issuance of the Series A-3
Preferred Shares, the Compamm ny amended the dividend and conversion terms of the Series A-1 and Series A-2 Preferred Shares. The
Compamm ny’s policy requires the evaluation of amendments to equity classified preferred shares qualitatively to determine whether they
are considered a modification or extinguishment. Based on this approach, the amendment to the terms of the Series A-1 and A-2
Preferred Shares was considered a modification and as a result, there was no adjustment to the carrying value of the Series A-1 and A-
2 Preferred Shares. The balance of the Series A-3 Preferred Share subsu cription receivabla e of $2.12 per share was called on May 5,
2016 by the Board of Directors and gross proceeds of $22.8 million were received by May 27, 2016.

Revenue from R&D services under collaboration agreements

Risk

CRISPR Therapeutics AG (CRISPR) has entered into material revenue
generating collaboration agreements in 2015 (Vertex Pharmaceuticals)
and 2016 (Casebia Therapeutics LLP). These arrangements were
accounted for as multiple element arrangements and each contain
separate Research and Development (R&D) servirr ce deliverables under
Generally Accepted Accounting Principles in the United States (US
GAAPAA ). R&D servirr ce revenue is recognized based on actual time
incurred using a relative selling price and recorded within Collaboration
Revenue on the Consolidated Statement of Operations.

The R&D servirr ce revenue is primarily composed of R&D services
performed by internal CRISPR R&D employees, the revenue is
calculated using projeo ct based employee timesheets. Given the manual
nature of the calculation, we identified a heightened risk related to the
opportunity of management to overstate the internally sourced R&D
service revenue, specifically through the inclusion of other employees
not providing R&D servirr ces under the collaboration agreements in the
Company’s calculation, which could result in a material revenue
misstatement.

Refer to Note 9 in the standalone statutory financial statements for
CRISPR’s accounting policy and further details.

For a sample of instances, we obtained confirmations directly from
CRISPR employees related to their involvement in the R&D servirr ce

samples, we reconciled the amount per the CRISPR employee
timesheet to management’s collaboration revenue calculation. We
tested each of the key contracts whereby we agreed the identified R&D
programs and FTE rates to the related collaboration agreements, and
recalculated revenue for the year based on the relative selling price
allocated to the R&D servirr ce deliverable of the arrangement.

We assessed R&D servirr ce revenue recognized by vouching subsequent
payments made by Verterr x and Casebia for amounts invoiced and
confirmed outstanding receivables as of period end. Additionally, we
analyzed the Company’s recognized collaboration revenue against
expectations based on the status of the research programs tested. We
tested the Company’s accounting and presentation of the Collaboration
Revenue in accordance with US GAAP, as well as for the statutory
standalone financials.

the establishment of Casebia (Joint Venture with Bayer

Risk

On December 19, 2015, CRISPR Therapeutics AG (CRISPR) entered
into an agreement to establish a joint venture investment (“Bayer Joint
Venture”) with Bayer Healthcare LLC (“Bayer”) to discover, develop and
commercialize new breakthrough therapeutics to cure blood disorders,
blindness, and congenital heart disease. The joint venture investment
into the partnership was legally formed during Q1 2016 and funding was
contributed by the two partirr es. In addition to the funding, CRISPR
contributed a license of its proprietary CRISPR-Cas9 gene-editing
technology and intellectual property for selected disease indications and
Bayer contributed its protein engineering expertirr se and relevant disease
know-how. Per the underlying agreement the risk the Crispr
Therapeutics AG bears is limited to the value of its contribution.

The Bayer Joint Venture investment is disclosed in the Note 9 to the
Consolidated Financial Statements.

The principal considerations for our determination that accounting for
the establishment of Casebia is a key audit matter are the materiality to
the standalone statutory financial statements, multiple elements of the
Bayer Joint Venture arrangement, as well as complexities in applying
the relevant accounting guidance for the formation of the joint venture
investment.

response

We analyzed the various clauses within the Bayer Joint Venture
agreement and discussed each with management to obtain an
understanding for the accounting treatment. We evaluated
management’s assessment of the variable interest considerations and
their judgements in determining the primary brr
eneficiary as well as the
risks borne by each party.

We obtained the underlying financial statements of Casebia in
connection with the impairment recorded. We evaluated the accounting
for the impairment in the participation value of the partnership in
accordance with the agreement.

Report orr n other legal requirements
We confirm that we meet the legal requirements on licensing according to the Auditor
Oversight Act (AOA) and independence (article 728 CO and article 11 AOA) and that there
are no circumstances incompatible with our independence.

In accordance with article 728a para. 1 item 3 CO and Swiss Auditing Standard 890, we
confirm that an internal control system exists, which has been designed for the preparation of
financial statements according to the instructions of the Board of Directors.

We recommend that the financial statements submitted to you be approved.

B. Compensation of the Board of Directors

Our Board of Directors adopted a non-employee director compensation policy, which became effective
upon the closing of our initial public offering in October 2016. Prior to that time, we did not compensate any
directors, other than Drs. Coles and Cagnoni, for service on our Board of Directors.

The non-employee director compensation policy currently in effect is designed to provide a total

directors. Under the non-employee director compensation policy, our non-employee directors are compensated as
follows:

•

•

•

•

each non-employee director receives an annual cash fee of $35,000 (CHF 34,466), $65,000 (CHF
64,009) for the chairman of the Board of Directors;

each non-employee director who is a member of the Audit Committee receives an additional annual
cash fee of $7,500 (CHF 7,386), $15,000 (CHF 14,771) for the Audit Committee chairman;

each non-employee director who is a member of the Compensation Committee receives an additional

granted an option to purchase 30,000 common shares upon his or her initial election and appointment,
which vest in substantially equal monthly installments during the 36 months following the grant date,
subject to continued service as a director; and

on the date of each annual meeting of stockholders, each non-employee director previously serving
who is re-elected to the board will be granted a non-qualified stock option to purchase 15,000 common
shares, which will vest in substantially equal monthly installments during the 12 months following his
or her re-election as a director, subject to continued service as a director through such date.

All cash fees are paid quarterly, in arrears, or upon the earlier resignation or removal of the non-employee

director. The amount of each payment is prorated for any portion of a quarter that a non-employee director is not
serving on our Board of Directors, based on the number of calendar days served by such non-employee director.

The directors’ compensation is paid without regard to achievement of corporate goals or objectives and it is

not conditioned or dependent upon the performance of the director.

Each non-employee director is also entitled to reimbursement for reasonable travel and other expenses
incurred in connection with attending meetings of the Board of Directors and any committee on which he or she
serves.

In connection with our initial public offering, each non-employee director serving on our Board of Directors
at that time was granted (i) in the case of each non-employee director who had not received compensation for his
service on the board of directors prior to the initial public offering, being Drs. Bolzon, Behbahini, George and
Woiwode and Mr. von Emster, a stock option to purchase 30,000 common shares, which vests in substantially
equal monthly installments during the 36 months following the initial public offering effective date, subject to
continued service as a director through such date and (ii) in the case of non-employees director who has
previously received equity compensation for services on the board of directors, being Dr. Coles and Cagnoni, a
stock option to purchase 15,000 common shares, which vests in substantially equal monthly installments during
the 12 months following the grant date, subject to continued service as a director through such date.

The Compensation Committee reviews and proposes to the Board of Directors the resolution to be submitted

to the Annual General Meeting of Shareholders for the total compensation of the Board of Directors.
