Management Overview

Intellia Therapeutics, Inc. ("we," "us," "our," "Intellia," or the "Company") is
a leading clinical-stage genome editing company, focused on developing
potentially curative therapeutics using CRISPR/Cas9-based technologies.
CRISPR/Cas9, an acronym for Clustered, Regularly Interspaced Short Palindromic
Repeats ("CRISPR")/CRISPR associated 9 ("Cas9"), is a technology for genome
editing, the process of altering selected sequences of genomic deoxyribonucleic
acid ("DNA"). To fully realize the transformative potential of CRISPR/Cas9-based
technologies, we are building a full-spectrum genome editing company, by
leveraging our modular platform, to advance in vivo and ex vivo therapies for
diseases with high unmet need by pursuing two primary approaches. For in vivo
applications to address genetic diseases, we deploy CRISPR/Cas9 as the therapy
that targets cells within the body. In parallel, we are developing ex vivo
applications to address immuno-oncology and autoimmune diseases, where we use
CRISPR/Cas9 as the tool to create the engineered cell therapy. Our deep
scientific, technical and clinical development experience, along with our robust
intellectual property ("IP") portfolio, have enabled us to unlock broad
therapeutic applications of CRISPR/Cas9 and related technologies to create new
classes of genetic medicine.

Our management's discussion and analysis of our financial condition and results
of operations are based upon our unaudited condensed consolidated financial
statements included in this Quarterly Report on Form 10-Q, which have been
prepared by us in accordance with accounting principles generally accepted in
the United States of America ("U.S. GAAP") for interim periods and with
Regulation S-X, promulgated under the Securities Exchange Act of 1934, as
amended. This discussion and analysis should be read in conjunction with the
unaudited condensed consolidated financial statements and the notes thereto
included elsewhere in this Quarterly Report on Form 10-Q as well as in
conjunction with the audited financial statements and notes thereto included in
our Annual Report on Form 10-K ("Annual Report") for the year ended December 31,
2022.

Treating-and potentially curing-a broad range of severe diseases will require
multiple gene editing approaches. With proprietary CRISPR/Cas9-based technology
at the core of our platform, we continue to add new capabilities to expand our
current solutions for addressing a multitude of life-threatening diseases. These
additions include our proprietary base editor and DNA writing technology, as
well as novel CRISPR enzymes, which provide us with the capabilities to achieve
multiple editing strategies.

We continue to advance our platform's modular solutions and research efforts on genome editing technologies as well as delivery and cell engineering capabilities to generate additional development candidates.



Our mission is to transform the lives of people with severe diseases by
developing curative genome editing treatments. We believe we can deliver on our
mission and provide long-term benefits for all of our stakeholders by focusing
on four key elements:

Develop curative CRISPR/Cas9-based medicines;

Advance our science;


                                       21

--------------------------------------------------------------------------------

Be the best place to make therapies; and

Focus on long-term sustainability.



Our strategy is to advance our full-spectrum genome editing company, focused on
developing and commercializing curative CRISPR/Cas9-based therapeutics, by
leveraging our modular platforms. All of our revenue to date has been
collaboration revenue. Since our inception and through March 31, 2023, we have
raised an aggregate of approximately $2,400.1 million to fund our operations
through our initial public offering ("IPO") and concurrent private placements,
follow-on public offerings, at-the-market offerings, and the sale of convertible
preferred stock, as well as through our collaboration agreements.

Our lead in vivo candidates, NTLA-2001 for the treatment of transthyretin
("ATTR") amyloidosis and NTLA-2002 for the treatment of hereditary angioedema
("HAE"), are the first CRISPR/Cas9-based therapy candidates to be administered
systemically, via intravenous infusion, for precision editing of a gene in a
target tissue in humans. In parallel, we are advancing multiple ex vivo
programs, wholly owned and in collaboration with partners, for the treatment of
immuno-oncology and autoimmune diseases.

Our Pipeline

In Vivo Programs



Our selection criteria include identifying diseases that originate in the liver;
have well-defined mutations that can be addressed by a knockout or insertion
approach; have readily measurable therapeutic endpoints with observable clinical
responses; and for which effective treatments are absent, limited or unduly
burdensome. Our initial in vivo indications target genetic liver diseases,
including our ATTR amyloidosis, HAE and alpha-1 antitrypsin deficiency ("AATD")
development programs. Our current efforts on in vivo delivery focus on the use
of lipid nanoparticles ("LNPs") for delivery of the CRISPR/Cas9 complex to the
liver.

Transthyretin ("ATTR") Amyloidosis Program



NTLA-2001 is the first investigational CRISPR-based therapy to be systemically
delivered to edit genes inside the human body and has the potential to be the
first single-dose treatment for ATTR amyloidosis. Delivered with our in vivo LNP
technology, NTLA-2001 offers the possibility of halting and reversing the
disease by driving a deep, consistent and potentially lifelong reduction in
transthyretin ("TTR") protein after a single dose. NTLA-2001 is being evaluated
in a Phase 1, two-part, open-label study in adults with hereditary transthyretin
amyloidosis. The trial consists of two arms; one arm to evaluate NTLA-2001 for
ATTR with cardiomyopathy ("ATTR-CM") and the other arm for ATTR with
polyneuropathy ("ATTRv-PN").

In the ATTR-CM arm, we plan to submit an Investigational New Drug ("IND")
application in mid-2023. Subject to regulatory feedback, we plan to initiate a
global pivotal trial for ATTR-CM by the end of 2023. We plan to present
additional data from the ATTR-CM arm of the Phase 1 study in 2023, including
longer-term safety and durability data, as well as emerging clinical endpoints.

In the ATTRv-PN arm, in the first quarter of 2023, the planned enrollment of the
dose-expansion portion of the ATTRv-PN arm in the Phase 1 study was completed to
inform a pivotal study. We are preparing for a global pivotal study, which
includes discussions with regulatory authorities. We recently began redosing
patients in the 0.1 mg/kg cohort (n=3), the initial cohort and lowest dose
tested in the dose-escalation portion of the Phase 1 study, with the 55 mg dose
selected for the dose-expansion cohort. We plan to present additional clinical
data from the ATTRv-PN arm of the Phase 1 study in 2023.

NTLA-2001 is the subject of a co-development and co-promotion ("Co/Co")
agreement directed to our first collaboration target with Regeneron
Pharmaceuticals, Inc. ("Regeneron"), ATTR (the "ATTR Co/Co"), for which we are
the clinical and commercial lead party and Regeneron is the participating party.
Regeneron shares in approximately 25% of worldwide development costs and
commercial profits for the ATTR program. For more information regarding our
collaboration with Regeneron, see Note 7, "Collaborations and Other
Arrangements" of our condensed consolidated financial statements appearing
elsewhere in this Quarterly Report on Form 10-Q.

Hereditary Angioedema ("HAE") Program



NTLA-2002 is our wholly owned candidate for the treatment of HAE. NTLA-2002 is
designed to knock out the kallikrein B1 ("KLKB1") gene in the liver, with the
potential to permanently reduce total plasma kallikrein protein and activity, a
key mediator of HAE. This investigational approach aims to prevent attacks for
people living with HAE by providing continuous reduction of
                                       22
--------------------------------------------------------------------------------
plasma kallikrein activity, following a single dose. It also aims to eliminate
the significant treatment burden associated with currently available HAE
therapies. NTLA-2002 is being evaluated in a Phase 1/2 study in adults with Type
I or Type II HAE.

On May 4, 2023, we announced that the first patient has been dosed in the global
Phase 2 portion of our Phase 1/2 clinical trial of NTLA-2002. Based on
encouraging study interest from both investigators and patients, we expect to
complete enrollment (n=25) in the second half of 2023. In March, we announced
that the U.S. Food and Drug Administration ("FDA") cleared our NTLA-2002 Phase 2
IND application. Additionally, the FDA granted Regenerative Medicine Advanced
Therapy ("RMAT") designation to NTLA-2002 for the treatment of HAE. In January
2023, we were awarded the Innovation Passport for NTLA-2002 by the U.K.
Medicines and Healthcare products Regulatory Agency ("MHRA"). We plan to present
additional clinical data from the Phase 1 portion of the first-in-human study in
2023. Data expected to be presented include updated safety, durability of
pharmacodynamic effect and attack-rate measures from all three patient cohorts.

Alpha-1 Antitrypsin Deficiency ("AATD") Program

NTLA-3001 for associated lung disease:



NTLA-3001 is our wholly owned, first-in-class CRISPR-mediated in vivo targeted
gene insertion development candidate for the treatment of AATD-associated lung
disease. It is designed to precisely insert a healthy copy of the SERPINA1 gene,
which encodes the alpha-1 antitrypsin ("A1AT") protein, with the potential to
restore permanent expression of functional A1AT protein to therapeutic levels
after a single dose. Our approach seeks to improve patient outcomes, including
eliminating the need for weekly intravenous infusions of A1AT augmentation
therapy or lung transplant in severe cases. We are conducting IND-enabling
activities for NTLA-3001 and we plan to submit an IND or IND-equivalent
application in the second half of 2023.

NTLA-2003 for associated liver disease:



NTLA-2003 is our wholly owned, in vivo knockout development candidate for the
treatment of AATD-associated liver disease. It is designed to inactivate the
SERPINA1 gene responsible for the production of abnormal A1AT protein in the
liver. This approach aims to halt the progression of liver disease and eliminate
the need for liver transplant in severe cases. We plan to complete the ongoing
IND-enabling activities for NTLA-2003 by the end of 2023.

In Vivo Research Programs



We continue to work on various liver-focused programs, such as hemophilia A and
hemophilia B, which we are co-developing with Regeneron, as well as other liver
targets, which we are working on both independently and in partnership with
Regeneron, that would leverage our capabilities to knockout, insert and make
consecutive edits to the genome.

We are further investigating delivery strategies that target tissues outside of
the liver. For example, we have presented preclinical data establishing
proof-of-concept for non-viral genome editing of bone marrow and hematopoietic
stem cells ("HSCs") in mice. This represented our first demonstration of
systemic in vivo genome editing in bone marrow using our proprietary non-viral
delivery platform. We believe these results extend our modular in vivo
capabilities to treat inherited blood disorders such as sickle cell disease. In
addition, we are collaborating with SparingVision SAS ("SparingVision") to
develop novel genomic medicines utilizing CRISPR/Cas9 technology for the
treatment of ocular diseases.

Ex Vivo Programs



We are advancing multiple preclinical programs, wholly owned and in
collaboration with partners, utilizing our allogeneic platform for the treatment
of immuno-oncology and autoimmune diseases. Our proprietary allogeneic cell
engineering platform is designed to avoid both T cell- and natural killer ("NK")
cell-mediated rejection, a key unsolved challenge with other investigational
allogeneic approaches.

Collaborations and Other Arrangements



To accelerate the development and commercialization of CRISPR/Cas9-based
products in multiple therapeutic areas, we have formed, and intend to seek other
opportunities to form, strategic alliances with collaborators who can augment
our leadership in CRISPR/Cas9 therapeutic development. We have existing
collaboration agreements with Regeneron, AvenCell Therapeutics, Inc.,
SparingVision, Kyverna Therapeutics, Inc. ("Kyverna"), and ONK Therapeutics, Ltd
("ONK"). See Note 7, "Collaborations and Other Arrangements" of our condensed
consolidated financial statements of this Quarterly Report on Form 10-Q for
additional information related to the terms of the agreements between us and our
collaborators.

The decrease in research and development expenses for the three months ended
March 31, 2023 compared to the three months ended March 31, 2022 was primarily
attributable to:

a $1.2 million increase in external costs related to the development of NTLA-2001, primarily due to an increase in spend on contracted services, offset by a decrease in spend related to drug components;

a $2.5 million increase in external costs related to the development of NTLA-2002, primarily due to an increase in spend on contracted services, drug components and consulting costs;

a $2.4 million increase in external costs related to NTLA-3001, primarily related to an increase in spend on drug components;

a $5.1 million decrease in external costs related to NTLA-5001, as we continue to wind down the program as part of the pivot to an allogeneic pipeline;

a $10.4 million increase in employee-related expenses primarily driven by the increase in personnel growth to support our lead programs;


a $4.2 million decrease in research materials and contracted services primarily
driven by a decrease in drug component expenses, partially offset by an increase
in contracted services to support our pipeline;

a $56.0 million decrease in expense related to the acquisition of Rewrite Therapeutics, Inc. in the first quarter of 2022;

a $4.8 million increase in facility-related expenses primarily related to rent, depreciation and technology expense allocated to research and development; and

a $6.7 million increase in stock-based compensation driven by our larger workforce.

General and Administrative



General and administrative expenses increased by $5.0 million to $27.4 million
during the three months ended March 31, 2023, compared to $22.4 million during
the three months ended March 31, 2022. This increase was primarily related to
employee-related expenses, including an increase in stock-based compensation of
$2.1 million, driven by our larger workforce.

Other Income (Expense), Net

The increase in other income (expense) of $11.5 million is primarily related to an $11.4 million increase in interest income.

Liquidity and Capital Resources



Since our inception through March 31, 2023, we have raised an aggregate of
approximately $2,400.1 million to fund our operations through our collaboration
agreements, our initial public offering and concurrent private placements,
follow-on public offerings, at-the-market offerings and the sale of convertible
preferred stock.

As of March 31, 2023, we had $1,158.6 million in cash, cash equivalents and marketable securities.



We are eligible to earn a significant amount of milestone payments and
royalties, in each case, on a per-product basis under our collaborations with
Novartis Institutes for BioMedical Research, Inc. ("Novartis"), SparingVision
and ONK, on a per-target basis under our collaboration with Regeneron and upon
achievement of certain events under our collaboration with Kyverna. Our ability
to earn these milestone payments and the timing of achieving these milestones is
dependent upon the outcome of our research and development activities and is
uncertain at this time. Our rights to payments under our collaboration
agreements are our only committed external source of funds.

At-the-Market Offering Programs



In August 2019, we entered into an Open Market Sale Agreement (the "2019 Sale
Agreement") with Jefferies LLC ("Jefferies"), under which Jefferies was able to
offer and sell, from time to time in "at-the-market" offerings, shares of our
common stock having aggregate gross proceeds of up to $150.0 million. We agreed
to pay to Jefferies cash commissions of 3.0% of the gross proceeds of sales of
common stock under the 2019 Sale Agreement.

During the first quarter of 2022, we issued 579,788 shares of our common stock
in a series of sales at an average price of $69.43 per share in accordance with
the 2019 Sale Agreement, for aggregate net proceeds of $38.9 million after
payment of cash commissions to Jefferies and approximately $0.2 million related
to legal, accounting and other fees in connection with the sales. The 2019 Sale
Agreement expired in the third quarter of 2022.

In March 2022, we entered into an Open Market Sale Agreement (the "2022 Sale
Agreement") with Jefferies, under which Jefferies is able to offer and sell,
from time to time in "at-the-market" offerings, shares of our common stock
having aggregate gross proceeds of up to $400.0 million. We agreed to pay to
Jefferies cash commissions of 3.0% of the gross proceeds of sales of common
stock under the 2022 Sale Agreement.

During the year ended December 31, 2022, we issued 3,395,339 shares of our
common stock, in a series of sales, at an average price of $57.43 per share, in
accordance with the 2022 Sale Agreement for aggregate net proceeds of $189.0
million, after payment of cash commissions to Jefferies and approximately $0.1
million related to legal, accounting and other fees in connection with the
sales. During the quarter ended March 31, 2023, we issued 35,349 shares of our
common stock, in a series of sales, at an average price of $44.58 per share, in
accordance with the 2022 Sale Agreement for aggregate net proceeds of $1.5
million, after payment of cash commissions to Jefferies and approximately $0.1
million related to legal, accounting and other fees in connection with the
sales. As of March 31, 2023, $203.4 million in shares of common stock remain
eligible for sale under the 2022 Sale Agreement.

Funding Requirements



Our primary uses of capital are, and we expect will continue to be, research and
development research materials and contracted services, clinical trial costs,
compensation and related expenses, laboratory and office facilities, research
supplies, legal and regulatory expenses, patent prosecution filing and
maintenance costs for our licensed IP, milestone and royalty payments and
general overhead costs. During 2023, we expect our expenses to increase compared
to prior periods in connection with our ongoing activities as we continue to
grow our research and development team, develop our clinical programs and
advance additional programs into clinical development.

Because our lead programs are still in the early clinical stage and the outcome
of these efforts is uncertain, we cannot estimate the actual amounts necessary
to successfully complete the development and commercialization of any future
product candidates or whether, or when, we may achieve profitability. Until such
time as we can generate substantial product revenues, if ever, we
                                       26
--------------------------------------------------------------------------------
expect to finance our ongoing cash needs through equity financings and
collaboration arrangements. We receive cost reimbursements from Regeneron for
the ATTR and hemophilia programs. Additionally, we are eligible to earn
milestone payments and royalties, in each case, on a per-product basis under our
collaborations with Novartis, SparingVision and ONK, on a per-target basis under
our collaboration with Regeneron, and upon achievement of certain events with
Kyverna, subject to the provisions of our agreements with each of them. Except
for these sources of funding, we will not have any committed external source of
liquidity. To the extent that we raise additional capital through the future
sale of equity, the ownership interest of our stockholders will be diluted, and
the terms of these securities may include liquidation or other preferences that
adversely affect the rights of our existing stockholders. If we raise additional
funds through collaboration arrangements in the future, we may have to
relinquish valuable rights to our technologies, future revenue streams or
product candidates or grant licenses on terms that may not be favorable to us.
If we are unable to raise additional funds through equity financings when
needed, we may be required to delay, limit, reduce or terminate our product
development or future commercialization efforts or grant rights to develop and
market product candidates that we would otherwise prefer to develop and market
ourselves.

Outlook

Based on our research and development plans and our expectations related to the
progress of our programs, we expect that our cash, cash equivalents and
marketable securities as of March 31, 2023, as well as research and cost
reimbursement funding from our collaboration agreements, will enable us to fund
our ongoing operating expenses and capital expenditure requirements beyond the
next 24 months, excluding any potential milestone payments or extension fees
that could be earned and distributed under our collaboration agreements or any
strategic use of capital not currently in the base case planning assumptions. We
have based this estimate on current assumptions that may prove to be wrong, and
we could use our capital resources sooner than we expect.

Our ability to generate revenue and achieve profitability depends significantly
on our success in many areas, including: developing our delivery technologies
and our CRISPR/Cas9 technology platform; selecting appropriate product
candidates to develop; completing research and preclinical and clinical
development of selected product candidates; obtaining regulatory approvals and
marketing authorizations for product candidates for which we complete clinical
trials; developing a sustainable and scalable manufacturing process for product
candidates; launching and commercializing product candidates for which we obtain
regulatory approvals and marketing authorizations, either directly or with a
collaborator or distributor; obtaining market acceptance of our product
candidates; addressing any competing technological and market developments;
negotiating favorable terms in any collaboration, licensing, or other
arrangements into which we may enter; maintaining good relationships with our
collaborators and licensors; maintaining, protecting, and expanding our
portfolio of IP rights, including patents, trade secrets, and know-how; and
attracting, hiring, and retaining qualified personnel.

Net cash used in operating activities



Net cash used in operating activities of $109.3 million during the three months
ended March 31, 2023 primarily reflects the increased spend in our research and
development activities, offset in part by the receipt of $3.4 million in
payments from our collaboration partners during that period. Net cash used in
operating activities of $79.8 million during the three months ended March 31,
2022 primarily reflects the increased spend in our research and development
activities, offset in part by the receipt of $2.0 million in payments from our
collaboration partners during that period.
                                       27

--------------------------------------------------------------------------------

Net cash (used in) provided by investing activities



During the three months ended March 31, 2023, our investing activities used cash
of $122.2 million. The decrease in the three months ended March 31, 2023 is
primarily due to $382.0 million in marketable securities purchased, offset in
part by $263.6 million of marketable securities maturing, and $3.8 million in
cash for the purchase of property and equipment. Cash provided by investing
activities in the three months ended March 31, 2022 is primarily due to $93.7
million in marketable securities maturing, offset in part by $44.8 million in
net cash for the acquisition of Rewrite and $1.4 million in cash for the
purchase of property and equipment.

Net cash provided by financing activities



Net cash provided by financing activities of $2.2 million during the three
months ended March 31, 2023 includes $1.5 million in net proceeds from
at-the-market offerings and $0.8 million in cash received from the exercise of
stock options. Net cash provided by financing activities of $47.3 million during
the three months ended March 31, 2022 includes $38.9 million in net proceeds
from at-the-market offerings and $8.4 million in cash received from the exercise
of stock options.
