Overview



We are a clinical-stage biopharmaceutical company currently focused on
developing differentiated therapies for patients with gastrointestinal, or GI,
diseases. Our most advanced program, MET642, targets the farnesoid X receptor,
or FXR, which is central to modulating GI and liver diseases.

Prior to February 2022, we were developing another FXR agonist, MET409, for the
treatment of non-alcoholic steatohepatitis, or NASH, a liver disease
characterized by excess liver fat, inflammation and fibrosis. While we believe
these two compounds demonstrate potential for differentiated treatments in both
monotherapy and combination treatment for NASH, given recent clinical outcomes
of our programs relative to competing programs, reduced investor sentiment in
NASH, and the significant resources required to pursue further development in
NASH, we elected to discontinue future development of our FXR program in NASH
while prioritizing our resources and efforts toward the development of MET642
for the treatment of Ulcerative Colitis, or UC, one of the two primary types of
Inflammatory Bowel Disease, or IBD. We were also developing small molecule
inhibitors of HSD17?13 for the treatment of NASH. HSD17?13 is a genetically
validated target for advanced liver disease. In April 2022, we completed a
corporate restructuring plan, or Restructuring Plan, that resulted in the
reduction of approximately 50% of our workforce, primarily consisting of our
research organization, which consequently resulted in the discontinued
development of our hydroxysteroid dehydrogenase, or HSD, program.

In September 2022, we entered into a License Agreement, or the HSD License
Agreement, with a portfolio company of Foresite Labs, pursuant to which we
granted the licensee an exclusive license to research, manufacture, develop and
commercialize pharmaceutical products containing our proprietary HSD inhibitors
in all fields of use and on a worldwide basis. We received an upfront payment of
$1.25 million in October 2022 in connection with our entry into the HSD License
Agreement, and we are eligible to receive up to an aggregate of $4.25 million in
milestone payments upon the achievement of certain regulatory milestone events,
and we will also be entitled to receive royalties on tiers of annual net sales
of pharmaceutical products sold pursuant to the HSD License Agreement at rates
in the low single digits until the expiration of the patent rights in each
country sales are made.

We believe FXR plays a key role in the treatment of IBD, including UC. FXR is
highly expressed by intestinal epithelial cells and plays a key role in healthy
intestinal function by maintaining the epithelial barrier, reducing bacterial
translocation into the intestinal wall and regulating the innate immune
response. FXR-based therapies in IBD address multiple aspects of IBD
pathogenesis without the immunosuppression inherent to other advanced-line
therapies.

IBD is a significant global health issue and is thought to occur due to a
maladaptive immune response to gut microbes. UC and Crohn's disease are the two
primary types of IBD. Patients with IBD can suffer from abdominal pain and
bloody diarrhea and also be at increased risk of colorectal cancer. The global
incidence of IBD is increasing and as of 2015, it was estimated that there were
3.1 million people in the United States with IBD. Our first clinical
investigation of FXR therapy in IBD will be focused on patients with UC.

We believe an oral, once-daily therapy with FXR agonists could be an attractive
treatment option for UC patients that may prefer oral administration instead of
injectable biologics that are cumbersome to administer chronically. In
preclinical animal studies with our current and previous FXR agonist product
candidates, we have observed statistically significant improvements in colon
histology and at levels similar to that of a mouse antibody which targets
IL-12/23. The IL-12/23 pathway is the target of current approved biologic
therapies.

To date, we have devoted substantially all of our resources to organizing and
staffing our company, business, planning, raising capital, researching,
discovering and developing our pipeline in FXR and other drug targets and
general and administrative support for these operations. We do not have any
products approved for sale and have not generated any product sales. We have
funded our operations primarily through the private placement of convertible
preferred stock, the issuance of long-term debt, and the sale of common stock
from our initial public offering, or IPO, and our at-the-market equity offering
program, or ATM offering program. Through September 30, 2022, we have raised
gross proceeds of approximately $124.8 million from the issuance of convertible
preferred stock, $15.0 million under our K2 Loan Agreement (as defined below)
and $107.7 million from the sale of common stock from our IPO and our ATM
offering program. As of September 30, 2022 and December 31, 2021, we had cash,
cash equivalents, and short-term investments of $52.8 million and $76.4 million,
respectively.

                                       17
--------------------------------------------------------------------------------


We have incurred net losses since our inception. Our net losses were
$24.7 million and $48.7 million for the nine months ended September 30, 2022 and
2021, respectively. As of September 30, 2022, we had an accumulated deficit of
$207.6 million. Our net losses may fluctuate significantly from
quarter-to-quarter and year-to-year, depending on the timing of our clinical
trials and preclinical studies and our expenditures on other development
activities. We expect our expenses and operating losses will increase as MET642
or any future product candidates advance through clinical trials, and as we
expand our clinical, regulatory, quality and manufacturing capabilities, incur
significant commercialization expenses for marketing, sales, manufacturing and
distribution, if we obtain marketing approval for MET642 or any future product
candidate, and incur additional costs associated with operating as a public
company.

We do not expect to generate any revenues from product sales unless and until we
successfully complete development and obtain regulatory approval for one or more
product candidates, which will not be for many years, if ever. Accordingly,
until such time as we can generate significant revenue from sales of MET642 or
any future product candidate, if ever, we expect to finance our operations
through a combination of equity offerings, debt financings, additional
borrowings under the K2 Loan Agreement, strategic transactions, collaborations,
and other similar arrangements. However, we may be unable to raise additional
funds or enter into such other arrangements when needed on favorable terms or at
all. Our failure to raise capital or enter into such other arrangements when
needed would have a negative impact on our financial condition and could force
us to delay, reduce or terminate our development programs or other operations,
or grant rights to develop and market product candidates that we would otherwise
prefer to develop and market ourselves.

Proposed Merger with Equillium



On September 6, 2022, we entered into an Agreement and Plan of Merger, as
amended on October 26, 2022, the Merger Agreement, with Equillium, Inc., a
Delaware corporation, or Equillium, Equillium Acquisition Sub, Inc., a Delaware
corporation and a wholly owned subsidiary of Equillium, or Acquisition Sub,
Triumph Acquisition Sub, Inc., a Delaware corporation and wholly owned
subsidiary of Acquisition Sub, or Acquisition Sub II, and Triumph Merger Sub,
Inc., a Delaware corporation and a wholly owned subsidiary of Acquisition Sub
II, or Merger Sub, pursuant to which, among other matters, and subject to the
satisfaction or waiver of certain closing conditions described in the Merger
Agreement, Merger Sub will be merged with and into the Company, or the Merger,
and the Company will continue as the surviving corporation and an indirect,
wholly owned subsidiary of Equillium.

Pursuant to the Merger Agreement, each share of our common stock issued and
outstanding immediately prior to the closing of the Merger, or the Closing, will
be cancelled and converted into the right to receive consideration per share
consisting of (i) the exchange ratio, or the Exchange Ratio, determined by
dividing (x) (a) 125% of our net cash as of the Closing, by (b) the price per
share of Equillium's common stock, par value $0.0001 per share, or Equillium
Common Stock, determined based on the 10 day trading volume weighted average
price per share of Equillium Common Stock calculated 10 trading days prior to
the date of the Closing, or the Closing Date, provided that the price per share
of Equillium Common Stock shall be no less than $2.70 and no more than $4.50 by
(y) the aggregate fully diluted shares of our common stock, plus (ii) any cash
payable in lieu of fractional shares of Equillium Common Stock.

The consummation of the Merger is subject to certain closing conditions,
including (i) our net cash being no less than $23,000,000, (ii) the absence of
certain legal impediments, (iii) the effectiveness of a registration statement
on Form S-4 filed with the SEC on October 27, 2022, (iv) adoption of the Merger
Agreement by the holders of a majority of our outstanding common stock at a
meeting of our stockholders, and (v) approval of the issuance of shares of
Equillium Common Stock in the Merger by the majority of the votes cast at a
meeting of Equillium's stockholders (provided that a quorum exists). The Merger
Agreement has been approved by our board of directors and Equillium's board of
directors.

The Merger Agreement contains certain termination rights for both Equillium and
us and further provides that, in connection with the termination of the Merger
Agreement by us under certain circumstances, including termination by us to
accept and enter into a definitive agreement with respect to a superior
proposal, we must pay Equillium a termination fee of $1.25 million. In
connection with the termination of the Merger Agreement by Equillium under
certain circumstances, including termination by Equillium to accept and enter
into a definitive agreement with respect to a superior proposal, Equillium must
pay us a termination fee of $1.75 million.

Although we have entered into the Merger Agreement and expect to devote
significant time and resources to successfully consummate the proposed Merger,
there can be no assurances that we will be able to do so on a timely basis, or
at all. Further, the consummation of the Merger may not deliver the anticipated
benefits or maximize stockholder value. If, for any reason, the Merger is not
consummated, we will reconsider our strategic alternatives and could pursue a
variety of strategic alternatives similar to the Merger, including, but not
limited to, a merger, sale, or other business combination, a strategic
partnership with one or more parties, or the licensing, sale or divestiture of
our programs, with the ultimate goal of identifying the opportunity that would,
in the opinion of our board of directors, maximize stockholder value, including
a liquidation of Metacrine and the distribution of any available cash.

We retained MTS Health Partners, L.P., or MTS Partners, as our financial advisor
in connection with the Merger, and MTS Securities, LLC, an affiliate of MTS
Partners, or MTS, performed a liquidation analysis of Metacrine based upon
information provided to MTS by our management. MTS computed the total equity
value of Metacrine in a liquidation to be approximately $27.3 million,
calculated as approximately $55.5 million of cash as of June 30, 2022, less
wind-down costs of approximately $29.5 million, plus an assumed upfront cash
value from the HSD License Agreement of $1.25 million, as compared to our
then-current market capitalization of approximately $20.6 million. The analysis
assumed a liquidation date of November 30, 2022, that all wind-down costs were
paid in full, employees were severed by November 30, 2022, all employee-related
restructuring and severance costs are paid in full, and, to be conservative,
that no funds were retained in reserve for unknown or contingent liabilities.
MTS estimated a liquidation value of approximately $27.3 million to our
stockholders in a potential liquidation, or $0.58 per share.

Financial Operations Overview

Revenues



To date, we have not generated any revenues from the commercial sale of any
products, and we do not expect to generate revenues from the commercial sale of
any products for the foreseeable future, if ever. In the future, we may generate
revenue pursuant to the HSD License Agreement in the form of milestone payments
upon the achievement of certain regulatory milestone events and royalties on
tiers of annual net sales at rates in the low single digits. In October 2022, we
received a one-time upfront payment of $1.25 million in connection with our
entry into the HSD License Agreement.

Research and Development Expenses



To date, our research and development expenses have related primarily to
discovery efforts and preclinical and clinical development of our product
candidates. Research and development expenses are recognized as incurred and
payments made prior to the receipt of goods or services to be used in research
and development are capitalized until the goods or services are received.

Research and development expenses include:

• salaries, payroll taxes, employee benefits and stock-based compensation

charges for those individuals involved in research and development efforts;

• external research and development expenses incurred under agreements with

contract research organizations, or CROs, investigative sites and

consultants to conduct our preclinical, toxicology and clinical studies;

• costs related to manufacturing our product candidates for clinical trials

and preclinical studies, including fees paid to third-party manufacturers;




  • laboratory supplies;


  • costs related to compliance with regulatory requirements; and

• facilities, depreciation and other allocated expenses, which include direct

and allocated expenses for rent, maintenance of facilities, insurance,

equipment and other supplies.




The following table summarizes our research and development expenses allocated
by program for the three and nine months ended September 30, 2022 and 2021 (in
thousands):


                                              Three Months Ended            Nine Months Ended
                                                 September 30,                September 30,
                                              2022           2021           2022          2021
Third-party research and development

FXR program                                $      799      $  10,996     $    6,916     $  27,323
Other research programs                             2            405            236         1,264
Total third-party research and
development expenses                              801         11,401          7,152        28,587
Unallocated expenses                              521          2,671          3,159         7,710
Total research and development expenses    $    1,322      $  14,072     $  

10,311 $ 36,297

Unallocated expenses consist primarily of our internal personnel related costs, facility costs, and lab supplies.



Our Restructuring Plan, which we completed in April 2022, resulted in the
reduction of approximately 50% of our workforce, primarily consisting of our
research organization, and as a result, we will not incur research expenses for
the foreseeable future. We expect our development expenses will fluctuate in the
future as we review the development plan and timeline of our FXR program in IBD
and depending on whether the proposed Merger is consummated. We cannot determine
with certainty the timing of initiation, the duration or the completion costs of
current or future clinical trials of MET642 or any future product candidate due
to the inherently unpredictable nature of preclinical and clinical development.
Clinical and preclinical development timelines, the probability of success and
development costs can differ materially from expectations. We will need to raise
substantial additional capital in the future if the proposed Merger with
Equillium is not consummated. In addition, we cannot forecast whether MET642 or
any future product candidate may be subject to future collaborations, when such
arrangements will be secured, if at all, and to what degree such arrangements
would affect our development plans and capital requirements.

Our development costs may vary significantly based on factors such as:


  • per patient trial costs;


  • the number and scope of preclinical studies;


  • the number of trials required for approval;


  • the number of sites included in the trials;


  • the countries in which the trials are conducted;


  • the length of time required to enroll eligible patients;


  • the number of patients that participate in the trials;


  • the number of doses that patients receive;


                                       19

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



  • the drop-out or discontinuation rates of patients;

• potential additional safety monitoring requested by regulatory agencies;




  • the duration of patient participation in the trials and follow-up;


  • the phase of development of the product candidate;


  • the efficacy and safety profile of the product candidate; and

• the extent to which we collaborate with biopharmaceutical companies for the

development and potential commercialization of the product candidate.

General and Administrative Expenses



General and administrative expenses consist primarily of salaries and
employee-related costs, including stock-based compensation, for personnel in
executive, finance, and other administrative functions. Other significant costs
include facility-related costs, legal fees relating to intellectual property and
corporate matters, professional fees for accounting and consulting services, and
insurance. We anticipate that our general and administrative expenses will
increase in the future to support our development and other commercial
activities if MET642 or any future product candidate receives marketing
approval. We also expect that our general and administrative expenses will
increase due to the transaction costs associated with the proposed Merger with
Equillium and potential related litigation.

Restructuring Charges



Restructuring charges consist primarily of (i) one-time payments relating to
severance obligations and other customary employee benefits and the acceleration
of the vesting of certain equity awards in connection with the staff reduction
conducted pursuant to our Restructuring Plan and (ii) third-party costs
associated with the discontinuation of our HSD program. Refer to Note 9 in our
unaudited condensed consolidated financial statements for further discussion.

Gain from Lease Termination and Asset Sale



Gain from lease termination and asset sale relates to the termination of our
Corporate Lease (as defined below) in March 2022 and the sale of personal
property to Belharra Therapeutics, Inc., or Belharra. Refer to Note 3 in our
unaudited condensed consolidated financial statements for further discussion.

Total Other Income (Expense)

Total other income (expense) consists primarily of interest income from our cash, cash equivalents, and short-term investments and interest expense under our K2 Loan Agreement.

Research and Development Expenses. Research and development expenses were $1.3
million and $14.1 million for the three months ended September 30, 2022 and
2021, respectively. The decrease in research and development expenses of $12.8
million when comparing the three months ended September 30, 2022 and 2021 was
primarily due to decreases of $8.4 million in clinical trial expenses and $1.4
million in manufacturing expenses related to our FXR program, $1.6 million in
personnel costs, including $0.5 million in non-cash stock-based compensation,
$0.5 million in facilities, information technology, and laboratory supplies
expenses, $0.5 million in preclinical and toxicology expenses, and $0.3 million
in third-party medicinal chemistry expenses.

Research and development expenses were $10.3 million and $36.3 million for the
nine months ended September 30, 2022 and 2021, respectively. The decrease in
research and development expenses of $26.0 million when comparing the nine
months ended September 30, 2022 and 2021 was primarily due to decreases of $16.6
million in clinical trial expenses and $1.5 million in manufacturing expenses
related to our FXR program, $3.4 million in personnel costs, including $1.0
million in non-cash stock-based compensation, $2.3 million in preclinical and
toxicology expenses, $1.5 million in facilities, information technology, and
laboratory supplies expenses, and $0.6 million in third-party medicinal
chemistry expenses.

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



General and Administrative Expenses. General and administrative expenses were
$3.8 million and $4.0 million for the three months ended September 30, 2022 and
2021, respectively. The decrease in general and administrative expenses of $0.2
million when comparing the three months ended September 30, 2022 and 2021 was
primarily due to a decrease of $1.0 million in personnel costs, including $0.5
million in non-cash stock-based compensation, partially offset by an increase of
$0.8 million in consulting, professional services and other public company
related expenses.

General and administrative expenses were $12.7 million and $11.7 million for the
nine months ended September 30, 2022 and 2021, respectively. The increase in
general and administrative expenses of $1.0 million when comparing the nine
months ended September 30, 2022 and 2021 was primarily due to increases of $0.9
million in consulting, professional services and other public company related
expenses and $0.1 million in facilities and information technology expenses.

Restructuring Charges. Restructuring charges were none for each of the three
months ended September 30, 2022 and 2021, and were $0.9 million and none for the
nine months ended September 30, 2022 and 2021, respectively. The increase in
restructuring charges when comparing the nine months ended September 30, 2022
and 2021 was primarily related to one-time payments of severance obligations and
other customary employee benefits made in connection with the staff reduction
resulting from the Restructuring Plan. Refer to Note 9 in our unaudited
condensed consolidated financial statements for further discussion.

Gain from Lease Termination and Asset Sale. Gain from lease termination and
asset sale were none for each of the three months ended September 30, 2022 and
2021, and were $0.5 million and none for the nine months ended September 30,
2022 and 2021, respectively. The increase in the gain from lease termination and
asset sale when comparing the nine months ended September 30, 2022 and 2021 was
primarily related to the termination of our Corporate Lease and sale of personal
property to Belharra in March 2022. Refer to Note 3 in our unaudited condensed
consolidated financial statements for further discussion.

Liquidity and Capital Resources



We have incurred net losses and negative cash flows from operations since our
inception and anticipate we will continue to incur net losses for the
foreseeable future. As of September 30, 2022 and December 31, 2021, we had cash,
cash equivalents, and short-term investments of $52.8 million and $76.4 million,
respectively.

Cash Flows

Operating Activities

Net cash used in operating activities was $24.4 million and $35.3 million for
the nine months ended September 30, 2022 and 2021, respectively. The net cash
used in operating activities during the nine months ended September 30, 2022 was
primarily due to our net loss of $24.7 million and $4.6 million of non-cash
charges, adjusted for $4.3 million in changes in operating assets and
liabilities. Non-cash charges for the nine months ended September 30, 2022
primarily consisted of $4.4 million of stock-based compensation, $0.5 million in
debt amortization expense, and $0.2 million in other non-cash charges, partially
offset by a $0.5 million gain from lease termination and asset sale related to
the termination of our Corporate Lease.

Net cash used in operating activities was $35.3 million for the nine months
ended September 30, 2021 and was primarily due to our net loss of $48.7 million,
adjusted for $6.5 million of non-cash charges and $6.9 million from changes in
operating assets and liabilities. Non-cash charges for the nine months ended
September 30, 2021 primarily consisted of $5.3 million of stock-based
compensation, $0.5 million of amortization on our right-of-use asset, $0.3
million of amortization of premiums/discounts on investments, and $0.4 million
in other non-cash charges.

Investing Activities

Net cash provided by investing activities of $28.2 million for the nine months
ended September 30, 2022 was primarily due to sales and maturities of short-term
investments of $40.2 million and proceeds from asset sale of $0.7 million,
partially offset by purchases of short-term investments of $12.7 million.

Net cash provided by investing activities of $26.8 million for the nine months
ended September 30, 2021 was primarily due to sales and maturities of short-term
investments of $65.9 million, partially offset by purchases of short-term
investments of $39.2 million.

Financing Activities

There was an immaterial amount of cash provided by financing activities for the nine months ended September 30, 2022.



Net cash provided by financing activities of $1.2 million for the nine months
ended September 30, 2021 was primarily due to $1.1 million of proceeds from
exercises of common stock options and $0.1 million of proceeds from the issuance
of shares from our employee stock purchase plan.

Loan Agreement



In August 2019, we borrowed $10.0 million in the first tranche under a loan and
security agreement, or the K2 Loan Agreement, with K2 HealthVentures Equity
Trust LLC, or K2, which was subsequently amended in March 2020 and October 2021.
In October 2021, we amended the K2 Loan Agreement and thereby replaced and
superseded the $10.0 million of existing term loan tranches with new term loan
tranches that enable us to borrow up to an aggregate of $45.0 million upon the
achievement of certain milestones. We have borrowed $15.0 million under the
first tranche, or the 2021 Refinancing Term Loans, and currently have $20.0
million in term loan tranches available to us upon the achievement of certain
milestones under the terms of the K2 Loan Agreement.

Term loans under the K2 Loan Agreement bear interest at a floating annual rate
equal to the greater of (i) the prime rate used by the lender plus 4.5% and
(ii) 7.75%. The monthly payments on the 2021 Refinancing Term Loans are
interest-only until July 1, 2023, and then subsequent to the interest-only
period, the 2021 Refinancing Term Loans will be payable in equal monthly
installments of principal plus accrued and unpaid interest, through April 1,
2025, the maturity date. We are required to make final fee payments equal to
$0.5 million on September 1, 2023 and 5.75% of the aggregate original principal
amount of the 2021 Refinancing Term Loans at the maturity date. We may elect to
prepay all, but not less than all, of the 2021 Refinancing Term Loans prior to
the maturity date, subject to a prepayment fee of up to 3.0% of the then
outstanding principal balance. After repayment, no term loan amounts may be
borrowed again.

Our obligations under the K2 Loan Agreement are secured by a security interest
in substantially all of our assets, other than our intellectual property. The K2
Loan Agreement includes customary affirmative and negative covenants and also
includes standard events of default, including an event of default based on the
occurrence of a material adverse event, and a default under any agreement with a
third party resulting in a right of such third party to accelerate the maturity
of any debt in excess of $0.3 million. The negative covenants include, among
others, restrictions on us transferring collateral, incurring additional
indebtedness, engaging in mergers or acquisitions, paying cash dividends or
making other distributions, making investments, creating liens, selling assets
and making any payment on subordinated debt, in each case subject to certain
exceptions. Upon the occurrence and continuance of an event of default, the
lender may declare all outstanding obligations immediately due and payable and
take such other actions as set forth in the K2 Loan Agreement. As of
September 30, 2022, we were in compliance with all applicable covenants under
the K2 Loan Agreement.

Sales Agreement

On October 4, 2021, we entered into a sales agreement, or the Sales Agreement,
with SVB Leerink LLC, or SVB Leerink, to sell shares of common stock from time
to time through our ATM offering program, under which SVB Leerink will act as
our sales agent. We have no obligation to sell any shares of common stock under
the Sales Agreement and may at any time suspend solicitation and offers under
the Sales Agreement. SVB Leerink will be entitled to compensation in an amount
of up to 3.0% of the gross proceeds of any shares of common stock sold under the
Sales Agreement. A maximum of $50.0 million of shares of common stock may be
sold under the Sales Agreement. We did not sell any shares of our common stock
under the Sales Agreement during the nine months ended September 30, 2022. As of
September 30, 2022, we may sell up to an additional $27.3 million of shares of
our common stock under the Sales Agreement and pursuant to our ATM offering
program, although we may not sell any shares under the Sales Agreement during
the pendency of the proposed Merger with Equillium.

Material Cash Requirements



Other than transaction costs related to the proposed Merger, and the requirement
under the Merger Agreement that we maintain a minimum net cash at the Merger
Closing of $23.0 million, our material cash requirements from known contractual
obligations have not changed materially since our Annual Report.

On March 11, 2022, we entered into an Agreement for Termination of Lease and
Voluntary Surrender of Premises, or Lease Termination Agreement, with ARE-SD
Region No. 30, LLC, or Landlord, to accelerate the termination of the operating
lease for our former corporate headquarters, or our Corporate Lease. Under the
terms of the Lease Termination Agreement, our Corporate Lease would terminate on
the later of March 31, 2022 and the date that Landlord notifies us that it has
executed a lease agreement with a third party for the premises. On March 31,
2022, or the Lease Termination Date, Landlord notified us that our Corporate
Lease had been terminated pursuant to the terms of the Lease Termination
Agreement. Since the Lease Termination Date, we have had no further obligations
under our Corporate Lease and have transitioned to a fully remote work
environment and no longer maintain a corporate headquarters. We believe that a
fully remote work environment will be adequate to meet our needs for the
immediate future, and that we will be able to obtain access to suitable physical
office space in the future to the extent necessary.

We believe that our existing cash, cash equivalents and short-term investments
will be sufficient to meet our material cash requirements through at least the
next twelve months based on our current operating plans. We expect to finance
our long-term cash requirements and obligations beyond the next twelve months
through a combination of existing cash and cash equivalents and equity offerings
and debt financings, as well as business combinations, collaborations and other
similar strategic alternatives. Our forecast of

                                       22
--------------------------------------------------------------------------------


the period of time through which our financial resources will be adequate to
support our operations is a forward-looking statement that involves risks and
uncertainties, and actual results could vary materially. We have based this
estimate on assumptions that may prove to be wrong or change, and we could
expend our capital resources sooner than we expect.

During the pendency of the proposed Merger, we are generally required to conduct
our business in the ordinary course consistent with past practice, and preserve
our business organization and material business relationships. Additionally, we
are subject to a variety of operating covenants that impose liquidity and
capitalization restrictions on the conduct of our business prior to the Closing.
Unless we obtain Equillium's prior written consent (which shall not be
unreasonably withheld, conditioned or delayed) and except (i) as expressly
permitted or expressly contemplated by the Merger Agreement, (ii) as required by
applicable laws or (iii) as set forth in the confidential disclosure letter we
delivered to Equillium, we may not, among other things and subject to certain
exceptions and aggregate limitations: pay any dividends, or repurchase, redeem
or otherwise acquire shares of our common stock; issue additional shares of our
common stock other than upon the exercise, settlement or vesting of outstanding
equity-based awards granted under our equity incentive plans; increase the
salary, compensation or benefits of our employees or hire, promote or terminate
(without cause) any employee; acquire or sell, lease, license, encumber or
dispose of any material properties, rights or assets; incur additional
indebtedness; make certain additional capital expenditures; assign, transfer or
license our intellectual property; amend, modify or enter into material
contracts; or commence any clinical trial of any product candidate.

Without taking into account the proposed Merger, our future cash requirements will depend on many factors, including:

• the scope, rate of progress and costs of our drug discovery, preclinical

development activities, laboratory testing and clinical trials for MET642 or


      any future product candidate;


  • the number and scope of clinical programs we decide to pursue;

• the extent to which we collaborate with biopharmaceutical companies for the

development and potential commercialization of MET642 or any future product

candidates;

• the scope and costs of manufacturing for MET642 or any future product

candidate and commercial manufacturing activities;

• the cost, timing and outcome of regulatory review of MET642 or any future


      product candidate;


   •  the costs of preparing, filing and prosecuting patent applications,

maintaining and enforcing our intellectual property rights and defending

intellectual property-related claims;

• the terms and timing of establishing and maintaining collaborations,


      licenses and other similar arrangements;


  • the terms and timing of any strategic transaction we may enter into;

• our efforts to enhance operational systems and our ability to attract, hire


      and retain qualified personnel, including personnel to support the
      development of MET642 or any future product candidate;


  • the costs associated with being a public company;

• the timing of any milestone and royalty payments to The Salk Institute for

Biological Studies, or other future licensors;

• the extent to which we acquire or in-license other product candidates and

technologies; and

• the cost associated with commercializing MET642 or any future product

candidate, if they receive marketing approval.




Without taking into account the proposed Merger, and until such time, if ever,
as we can generate substantial product revenues to support our cost structure,
we expect to finance our operations through a combination of equity offerings,
debt financings, strategic transactions, license agreements, collaborations, and
other similar arrangements. To the extent that we raise additional capital
through the sale of equity or convertible debt securities, the ownership
interest of our stockholders will be or could be diluted, and the terms of these
securities may include liquidation or other preferences that adversely affect
the rights of our common stockholders. Debt financing and equity financing, if
available, may involve agreements that include covenants limiting or restricting
our ability to take specific actions, such as incurring additional debt, making
capital expenditures or declaring dividends. If we raise funds through
collaborations, or other similar arrangements with third parties, we may have to
relinquish valuable rights to our technologies, future revenue streams, research
programs or product candidates or grant licenses on terms that may not be
favorable to us and/or may reduce the value of our common stock. If we are
unable to raise additional sufficient capital when needed, we may be required
to:

• delay, reduce or eliminate our development programs or other operations;

• enter into strategic transactions or grant rights to develop and market

product candidates that we would otherwise prefer to develop and market


      ourselves, or on terms that are less favorable than might otherwise be
      available;

• dispose of technology assets, or relinquish or license on unfavorable terms,


      our rights to technologies or any future product candidates that we
      otherwise would seek to develop or commercialize ourselves;

• pursue the sale of our company to a third party at a price that may result


      in a loss on investment for our stockholders; or


  • file for bankruptcy or cease operations altogether.

Any of these events could have a material adverse effect on our business, operating results and prospects.

Critical Accounting Estimates



Our management's discussion and analysis of our financial condition and results
of operations are based on our unaudited condensed consolidated financial
statements, which have been prepared in accordance with U.S. generally accepted
accounting principles. The preparation of these unaudited condensed consolidated
financial statements requires us to make estimates and judgments that affect the
reported amounts of assets, liabilities, and expenses and the disclosure of
contingent assets and liabilities in our unaudited condensed consolidated
financial statements. On an ongoing basis, we evaluate our estimates and
judgments, including those related to accrued expenses and stock-based
compensation. We base our estimates on historical experience, known trends and

                                       23
--------------------------------------------------------------------------------


events, and various other factors that are believed to be reasonable under the
circumstances, the results of which form the basis for making judgments about
the carrying values of assets and liabilities that are not readily apparent from
other sources. Actual results may differ from these estimates under different
assumptions or conditions.

While our significant accounting policies are described in more detail in Note 1
to our unaudited condensed consolidated financial statements appearing elsewhere
in this Quarterly Report, we believe the following accounting policies and
estimates to be most critical to the preparation of our unaudited condensed
consolidated financial statements.

Accrued Expenses



We make estimates of our accrued research and development expenses for services
performed by our vendors in connection with research and development activities
for which we have not yet been invoiced. This process involves reviewing open
contracts and purchase orders, communicating with our personnel to identify
services that have been performed on our behalf and estimating the level of
service performed and the associated cost incurred for the service when we have
not yet been invoiced or otherwise notified of the actual cost.

We make estimates of our accrued expenses as of each balance sheet date based on
facts and circumstances known to us at that time. We periodically confirm the
accuracy of our estimates with the service providers and make adjustments if
necessary. The significant estimates in our accrued research and development
expenses include the costs incurred for services performed by our vendors in
connection with research and development activities for which we have not yet
been invoiced.

We base our expenses related to research and development activities on our
estimates of the services received and efforts expended pursuant to quotes and
contracts with vendors that conduct research and development on our behalf. The
financial terms of these agreements are subject to negotiation, vary from
contract to contract and may result in uneven payment flows. There may be
instances in which payments made to our vendors will exceed the level of
services provided and result in a prepayment of the research and development
expense. In accruing service fees, we estimate the time period over which
services will be performed and the level of effort to be expended in each
period. If the actual timing of the performance of services or the level of
effort varies from our estimate, we adjust the accrual or prepaid expense
accordingly. Advance payments for goods and services that will be used in future
research and development activities are expensed when the activity has been
performed or when the goods have been received rather than when the payment is
made.

Although we do not expect our estimates to be materially different from amounts
actually incurred, if our estimates of the status and timing of services
performed differ from the actual status and timing of services performed, it
could result in us reporting amounts that are too high or too low in any
particular period. To date, there have been no material differences between our
estimates of such expenses and the amounts actually incurred.

Stock-Based Compensation Expense



Stock-based compensation expense represents the cost of the grant date fair
value of equity awards recognized over the requisite service period of the
awards (usually the vesting period) on a straight-line basis. We estimate the
fair value of all stock option grants using the Black-Scholes option pricing
model and recognize forfeitures as they occur. Estimating the fair value of
equity awards as of the grant date using valuation models, such as the
Black-Scholes option pricing model, is affected by assumptions regarding a
number of variables, including the fair value of the underlying common stock on
the date of grant, the risk-free interest rate, the expected stock price
volatility, the expected term of stock options, and the expected dividend yield.
Changes in the assumptions can materially affect the fair value and ultimately
how much stock-based compensation expense is recognized. These inputs are
subjective and generally require significant analysis and judgment to develop.
See Note 7 to our unaudited condensed consolidated financial statements included
elsewhere in this Quarterly Report for information concerning certain of the
specific assumptions we used in applying the Black-Scholes option pricing model
to determine the estimated fair value of our stock options granted the three and
nine months ended September 30, 2022 and 2021.
