You should read the following discussion and analysis of our financial condition
and results of operations together with our unaudited condensed consolidated
financial statements and related notes included in Part I, Item 1 of this
Quarterly Report. This discussion contains forward-looking statements that
involve risks and uncertainties, including those described in the section titled
"Special Note Regarding Forward Looking Statements." Our actual results and the
timing of selected events could differ materially from those discussed below.
Factors that could cause or contribute to such differences include, but are not
limited to, those identified below and those set forth under the section titled
"Risk Factors."
Overview
We aim to enable exceptional scientific outcomes by commercializing
transformative products for researchers to unlock deep, unbiased biological
information. Our initial product, the Proteograph Product Suite (Proteograph),
will leverage our proprietary engineered nanoparticle (NP) technology to provide
unbiased, deep, rapid and large-scale access across the proteome. Our
Proteograph Product Suite is an integrated solution that is comprised of
consumables, our SP100 automation instrument and the Proteograph Analysis Suite
software. Our Proteograph solution provides an easy-to-use workflow, which has
the potential to make proteomic profiling, and the analysis of the thousands of
samples needed to characterize the complex, dynamic nature of the proteome,
accessible for nearly any laboratory. We believe that characterizing and
understanding the full complexity of the proteome is foundational for
accelerating biological insights and will lead to broad potential end-markets
for proteomics, encompassing basic research and discovery, translational
research, diagnostics and applied applications. This full understanding of the
complexity of the proteome requires large-scale, unbiased and deep interrogation
of thousands of samples across time, which we believe is unavailable with the
proteomic approaches available today. We believe that our Proteograph has the
potential to enable researchers to perform proteomics studies at scale, similar
to the manner in which next generation sequencing (NGS) technologies have
transformed genomics.
Since we were incorporated in 2017, we have devoted substantially all of our
resources to research and development activities, including with respect to our
Proteograph Product Suite, establishing and maintaining our intellectual
property portfolio, hiring personnel, raising capital, building our commercial
infrastructure and providing general and administrative support for these
activities.
Our ability to generate product revenue sufficient to achieve profitability, if
ever, will depend on the successful commercialization of our Proteograph. We
plan to commercialize our Proteograph utilizing a three phase commercialization
plan that has been shown to be effective and optimal for introducing disruptive
products in numerous life sciences technology markets, including NGS. We have
completed the first Collaboration phase, during which we signed collaboration
agreements with a small number of key opinion leaders in proteomics, whose
assessment and validation of products can significantly influence other
researchers in their respective markets. We recently commenced the second, or
Limited Release, phase of our commercialization plan, and have generated our
first revenues from product sales during the second quarter of 2021. We will
continue to target sales of our Proteograph Product Suite to select sites
performing large-scale proteomics or genomics research. We will work closely
with these sites, which we expect will serve as models for the rest of the
market, to exemplify applications that demonstrate the unique value proposition
of our Proteograph. We expect this phase to continue through 2021 and lead into
the third phase of commercialization, Broad Release, in early 2022.
We are commercializing our Proteograph Product Suite as an integrated solution
comprising consumables, our SP100 automation instrument and software. Our
commercial strategy will focus on growing adoption by the research community of
our Proteograph, expanding the installed base and increasing utilization to
generate revenue from the purchase of Proteograph consumables. We expect a
highly efficient sales model since our Proteograph solution does not have a
large capital expenditure component and our workflow integrates with most
existing proteomics laboratories' workflows and also complements large-scale
genomics research.
We intend to broadly commercialize our Proteograph Product Suite through a
direct sales channel in the United States, and through both direct and
distributor sales channels in regions outside the United States. Given our stage
of commercialization, we are currently in the early stages of building sales,
marketing, support and product distribution
                                       20

capabilities. We intend to build the necessary infrastructure for these
activities in the United States, European Union, the United Kingdom, and
potentially other countries and regions, including Asia-Pacific, as we execute
on our three phase commercialization strategy for our Proteograph.
We leverage well-established unit operations to formulate and manufacture our
NPs and to assemble our assay kits at our facilities in Redwood City,
California. We procure some of our consumables, including components of our NPs,
from third-party manufacturers, which includes the commonly-available raw
materials needed for manufacturing our proprietary engineered NPs. We are
currently manufacturing using our pilot line and building out our manufacturing
capabilities as we ramp towards broad release. We obtain some of the reagents
and components used in our Proteograph Product Suite workflow from third-party
suppliers. While some of these reagents and components are sourced from a single
supplier, these products are readily available from numerous suppliers. While we
currently handle packaging of our Proteograph assay and the related consumables,
in the future, we may have our packaging outsourced to a third-party. While we
currently plan to handle filling of our Proteograph assay reagents both
internally and externally, in the future, we may have some of our internal
filling outsourced to a third-party. We conduct vendor and component
qualification for components provided by third-party suppliers and quality
control tests on all of our NPs. We will need to substantially expand our NP
manufacturing capabilities to enable the successful commercialization of our
Proteograph.
We have designed our SP100 automation instrument and have outsourced the
manufacturing of our SP100 to Hamilton Company, a leading manufacturer of
automated liquid handling workstations. We have entered into a non-exclusive
agreement with Hamilton that covers the manufacturing of our SP100 and its
continued supply on a purchase order basis. The agreement has an initial term
that runs three years following our commercial launch. Pricing for the supply of
our SP100 automation instrument is on a fixed schedule during the initial term
of the agreement, with tiered pricing dependent upon the number of units
purchased in a twelve-month period.
On December 8, 2020, we completed our IPO, in which we sold 10,592,106 shares of
Class A common stock at a price of $19.00 per share, resulting in net proceeds
of $183.9 million after deducting offering costs, underwriting discounts and
commissions. Concurrent with the IPO, we issued 7,105,262 shares of our common
stock in a private placement for net proceeds of $130.3 million after deducting
underwriting discounts and commissions. On February 1, 2021, we completed an
underwritten public offering of 1,650,000 shares of our Class A common stock at
a public offering price of $67.00 per share. We received net proceeds of $103.0
million after deducting offering costs, underwriting discounts and commissions
of $7.6 million.
During the six months ended June 30, 2021 and 2020, we incurred a net loss of
$33.0 million and $11.6 million, respectively. As of June 30, 2021, we had an
accumulated deficit of $88.4 million and cash, cash equivalents, and investments
of $517.8 million. We expect to continue to incur significant and increasing
losses and do not expect positive cash flows from operations for the foreseeable
future.
We expect our expenses to increase significantly in connection with our ongoing
activities, as we:
•continue to develop and commercialize our Proteograph Product Suite;
•attract, hire and retain qualified personnel;
•establish a sales, marketing, service, support and distribution infrastructure
as part of our commercialization efforts;
•build-out and expand our in-house NP manufacturing capabilities;
•continue to engage in research and development of other products and
enhancements to our Proteograph Product Suite;
•implement operational, financial and management information systems;
•obtain, maintain, expand, and protect our intellectual property portfolio; and
•build the infrastructure to operate as a public company.

PrognomIQ


In August 2020, we transferred certain assets related to human disease testing
to PrognomIQ, Inc. (PrognomIQ), a new wholly-owned subsidiary, in exchange for
all of its outstanding equity interests. Following the transfer, we completed a
pro-rata distribution to our stockholders of most of the shares of capital stock
of PrognomIQ. Following the distribution and a subsequent $55.0 million equity
financing of PrognomIQ, we hold approximately 19% of the outstanding capital
stock in PrognomIQ.
The rationale for this transaction was to enable the growth of ecosystems around
new applications that leverage unbiased, deep and large-scale proteomic
information. The transaction allows us to remain focused on our core strategy,
which is to be a provider, rather than a consumer, of proteomics solutions to
all customers across these ecosystems. By focusing on our role as a provider of
proteomics solutions, we are no longer potentially competing with, or creating
the perception that we are competing with, our customers. Our relationship with
PrognomIQ does not preclude us from selling our Proteograph Product Suite to any
customer in any geography, nor does it preclude our customers from using our
Proteograph in any way. PrognomIQ has indicated that it plans to combine the
protein data from our Proteograph solution with genomics and other -omics data,
to create a multi-omics approach to health and disease testing. We believe
PrognomIQ's use of proteomics and the potential for other similar companies that
use proteomics in their research and products will help us drive the adoption of
our Proteograph Product Suite in these applications. We have entered into
certain agreements with PrognomIQ.
Omid Farokhzad, Chief Executive Officer and Chair of our board of directors,
serves as the Chair of PrognomIQ's board of directors. Philip Ma, Ph.D., our
former Chief Business Officer, serves as the Chief Executive Officer of
PrognomIQ. Dr. Ma has fully transitioned to PrognomIQ and remains our consultant
through April 2022. In addition, three of our other employees have also
transitioned to PrognomIQ. We will be providing general transition services and
support, including laboratory and office space to PrognomIQ during the
transition period. We anticipate these services to continue through the first
half of 2021.
We granted PrognomIQ a non-exclusive license to certain patents and patent
applications that we own and a non-exclusive sublicense to certain patent
applications we exclusively licensed from BWH, in each case relating to our core
technology, to develop, manufacture and commercialize licensed products for the
field of human diagnostics on a worldwide basis. In consideration of the
non-exclusive sublicense to certain patent applications licensed from BWH,
PrognomIQ paid us a low-five digit figure, and would pay a low single digit
royalty, in an amount equivalent to what we would have to pay under our license
with BWH, on net sales of sublicensed products beginning with the first
commercial sale of a sublicensed product during the term of the agreement. We do
not view these amounts to be material to our financial condition and results of
operations nor do we expect these amounts to be material to us in the future. In
accordance with the non-exclusive license agreement with PrognomIQ, we entered
into a supply agreement with PrognomIQ in June 2021. The PrognomIQ supply
agreement provides that we will supply PrognomIQ with the Proteograph Product
Suite and associated consumables.
COVID-19 Pandemic
As a result of the COVID-19 pandemic, we could experience disruptions that could
severely impact our business. For example, we have experienced longer lead times
from Hamilton for orders of our SP100 automation instruments and may experience
delays and longer lead times from our other suppliers of critical hardware,
instrumentation and consumables used for product development and manufacturing
operations. Pandemic precautions and preventative measures may also impact our
commercialization plans due to restrictions on our customers' ability to access
laboratories, causing delays in the delivery and installation of our Proteograph
products, training such customers on our products, and their ability to conduct
research. The ongoing build-out of our expansion facilities may also be delayed
by COVID-related restrictions. Furthermore, COVID-19 has adversely affected the
broader economy and financial markets, resulting in an economic downturn that
could curtail the research and development budgets of our customers, our ability
to hire additional personnel and our financing prospects. Any of the foregoing
could harm our operations and we cannot anticipate all the ways in which it
could be adversely impacted by health epidemics such as COVID-19.

Components of Results of Operations
Revenue
We generate revenue from product sales, which includes sales of our Proteograph
Product Suite and associated consumables as well as our platform evaluation
agreements. In addition, we generate revenue from performing services and the
receipt of grant revenue for the reimbursement of research-related expenses. Our
revenue is primarily generated domestically. We intend to focus our commercial
efforts in the United States and expect to grow our international presence. A
portion of our revenue is generated by sales to a related party and we
anticipate a portion of our revenue to continue to be generated by such related
party. Our grant-funded activities are expected to decrease as a percentage of
total revenue as we continue to ramp up commercialization of our Proteograph
Product Suite and our product offerings.
Cost of Revenue
We utilize third-party manufacturers for production of our SP100 instrument and
we manufacture our NPs and assemble our assay kits internally. Cost of goods
sold consists primarily of costs of the components of Proteograph Product Suite,
including the SP100, consumables and software, and distribution-related expenses
such as logistics and shipping costs.
Research and Development Expenses
Research and development, or R&D, expenses include cost associated with
performing services under research and development service contracts and
research and development of our technology and product candidates. R&D expenses
consist primarily of employee compensation, including stock-based compensation,
and related benefits, laboratory supplies used for in-house research, consulting
costs, costs related to clinical studies for the collection of biological
samples for research use, which relate to the assets transferred to PrognomIQ,
and allocated overhead, including rent, depreciation, information technology and
utilities.
We plan to increase our investment in our R&D efforts related to our Proteograph
Product Suite, our product development pipeline and our proprietary engineered
NP and other technologies. Therefore, we expect R&D expenses will increase in
absolute dollars in future periods as we incur expenses associated with hiring
additional personnel, purchasing supplies and materials, and the allocation of
facility expense associated with the ongoing build-out of our expansion
facilities to support our R&D efforts.
Selling, General and Administrative Expenses
Selling, general and administrative expenses consist primarily of employee
compensation, including stock-based compensation, and related benefits for
executive management, sales and marketing, finance, administration and human
resources, legal, allocated overhead, professional service fees and other
general overhead costs to support our operations.
We expect to incur additional selling, general and administrative expenses as we
continue to invest in our personnel as we grow our commercial operations and
with the additional costs incurred as a result of operating as a public company,
including accounting, human resources, legal, insurance and investor relations
costs. As a result, we expect selling, general and administrative expenses to
increase in absolute dollars in future periods.
Interest Income
Interest income consists of interest earned on cash, cash equivalents and
investments.

Total other income decreased by $0.2 million, or 78%, from $0.3 million during
the three months ended June 30, 2020 to $0.1 million during the three months
ended June 30, 2021. Short-term interest rate yields decreased significantly
during fiscal year 2020 and remained low during the first half of fiscal year
2021. These decreases were partially offset quantitatively by higher amounts of
cash invested in money market funds and U.S. Treasury securities during fiscal
year 2020 and the first half of fiscal year 2021 as a result of multiple private
and public financing events.

Revenue increased by $1.1 million, or 463%, from $0.2 million during the six
months ended June 30, 2020 to $1.4 million during the six months ended June 30,
2021, due to sales of products related to our Proteograph Product Suite in the
three-months ended June 30, 2021. Revenue recognized primarily consisted of
sales of the Proteograph SP100 instrument and assay kits, platform evaluations,
and services, of which $0.4 million was related to related parties. Revenue
related to our grant-funded activities related to our SBIR grant from the NIH
declined between the two periods.

months ended June 30, 2020 to $13.2 million during the six months ended June 30,
2021. The increase was primarily due to an increase in product development
efforts related to our Proteograph Product Suite including $1.5 million in
employee compensation and other related costs and $1.8 million in stock-based
compensation due to growth in research and development personnel, $1.7 million
related to the expansion of facilities and maintenance and depreciation of
laboratory equipment, and $0.3 million in professional and consulting fees. This
was offset by a decrease in prototype materials of $(0.4) million as we enter
the Limited Release phase of our commercial plan and a decrease in clinical
study fees of $(0.6) million related to the costs associated with the ramp down
of site enrollment for clinical studies related to the collection of biological
samples for research use. These clinical studies are related to the assets
transferred to PrognomIQ.

$4.0 million increase in employee compensation and other related expenses, and a
$8.5 million stock-based compensation increase, as a result of an increase in
personnel, including the addition of key members of executive management. Other
increases are attributable to $0.5 million in marketing costs and $0.1 million

costs related to becoming a publicly traded company including a $0.9 million
increase in professional and consulting fees related to accounting and audit
services, a $0.7 million increase in corporate and patent legal matters, and a

Total other income decreased by $0.5 million, or 79%, from $0.6 million during
the six months ended June 30, 2020 to $0.1 million during the six months ended
June 30, 2021. Short-term interest rate yields decreased significantly during
fiscal year 2020 and remained low during the first half of fiscal year 2021.
These decreases were partially offset quantitatively by higher amounts of cash
invested in money market funds and U.S. Treasury securities during fiscal year
2020 and the first half of fiscal year 2021 as a result of multiple private and
public financing events.
Liquidity and Capital Resources
Since the date of our incorporation, we have not generated significant revenue
from product sales and have incurred significant operating losses and negative
cash flows from operations. Our operations have been funded primarily through
the sale and issuance of equity securities since inception. We anticipate that
we will continue to incur net losses and do not expect positive cash flows from
operations for the foreseeable future. However, based on our cash on hand, we
believe we will have adequate liquidity over the next twelve months following
the date of this Quarterly Report to operate our business and to meet our cash
requirements.
In connection with our IPO, we sold 10,592,106 shares of Class A common stock
and received net proceeds of $183.9 million after deducting offering costs,
underwriting discounts and commissions. Concurrent with the IPO, we issued
7,105,262 shares of our common stock in a private placement for net proceeds of
$130.3 million after deducting underwriting discounts and commissions. On
February 1, 2021, we completed an underwritten public offering of 1,650,000
shares of our Class A common stock and received net proceeds of $103.0 million
after deducting offering costs, underwriting discounts and commissions.
Cash Flows
The following table summarizes our cash flows for the periods indicated:
                                                                    Six Months Ended June 30,

Operating Activities
During the six months ended June 30, 2021, cash used in operating activities was
$25.2 million, which was attributable to a net loss of $(33.0) million and a net
change in our net operating assets and liabilities of $(6.1) million, partially
offset by non-cash charges of $13.9 million. Non-cash charges primarily
consisted of $12.5 million in stock-based compensation, $1.0 million of
depreciation and amortization and $0.4 million of net amortization of premiums
on available-for-sales securities. The change in our net operating assets and
liabilities was primarily due to an increase in inventory levels of $2.1
million, an increase in prepaid expenses, including insurance, of $2.8 million
related to being a public company and an increase in accounts receivable and
related party receivables of $1.2 million from commercial sales and other
receivables.
During the six months ended June 30, 2020, cash used in operating activities was
$9.9 million. which was attributable to a net loss of $(11.6) million and a net
change in our net operating assets and liabilities of $(0.4) million offset by
non-cash charges of $2.2 million. Non-cash charges primarily consisted of $1.4
million in stock-based compensation and $0.7 million of depreciation and
amortization. The change in our net operating assets and liabilities was
primarily due to a decrease of $0.5 million in accrued expenses and an increase
in other receivables of $0.3 million, partially offset by an increase in
deferred revenue of $0.3 million and an increase in deferred rent of $0.3
million.

Investing Activities
During the six months ended June 30, 2021, cash used in investing activities was
$52.3 million, which related to purchases of available-for-sale securities, net
of proceeds from maturities of $(49.3) million and $(2.9) million in payments
primarily for laboratory equipment.
During the six months ended June 30, 2020, cash provided by investing activities
was $10.3 million, which related to proceeds from maturities, net of purchases
of available-for-sale securities of $13.8 million, offset by $(3.5) million in
payments primarily for laboratory equipment.
Financing Activities
During the six months ended June 30, 2021, cash provided by financing activities
was $114.8 million. This was attributable to net proceeds of $103.0 million from
issuance of common stock upon our follow-on offering, net of issuance costs of
$(7.6) million, and $11.4 million in short-swing profits from a beneficial
owner.
During the six months ended June 30, 2020, cash provided by financing activities
was approximately $55.0 million, which was primarily attributable to proceeds
from sale of Series D-1 convertible preferred stock, net of issuance costs.

Contractual Obligations
The following table summarizes our contractual obligations as of December 31,
2020:
                                                       Payments due by period

In addition, we enter into agreements as a part of normal course of business
with various vendors, which are generally cancellable without material penalty
upon written notice. Payments associated with these agreements are not included
in this table of contractual obligations.
Our operating lease obligations reflect our lease obligations for our
headquarters facility in Redwood City, California. In June 2020, we amended the
lease agreement for this facility to expand the office and laboratory space
covered by the lease, extend the lease through February 2032, and increase the
annual base rent for the expanded premises. Upon occupancy of the expansion
facility that is anticipated to occur in the fourth quarter of 2021, the annual
base rent will be $0.9 million in the first 12 months of the lease term (subject
to an abatement period of nine months), and increases on an annual basis to $1.2
million in the final 12 months of the lease term. The amendment also provides
for tenant incentives in the amount of $2.4 million.
In April 2021, we entered into a lease amendment for this facility to further
expand the office and laboratory space for an approximate term of 11-years.
Payments associated with this operating lease agreement will result in
additional operating lease obligations not included in the above table of
approximately $160,000 per month plus operating expenses.
We have certain purchase commitments related to its inventory management with
certain manufacturing suppliers wherein the Company is required to purchase the
amounts forecasted in a blanket purchase order within a certain time period. The
contractual obligations represent future cash commitments and liabilities under
agreements with third parties and exclude orders for goods and services entered
into in the normal course of business that are not enforceable or subject to
change. These outstanding commitments amounted to $5.1 million as of June 30,
2021. These payments are not included in the table of contractual obligations
above.

Off-Balance Sheet Arrangements
Since the date of our incorporation, we have not engaged in any off-balance
sheet arrangements, as such term is defined in the rules and regulations of the
SEC.
Critical Accounting Policies, Significant Judgments and Use of Estimates
The discussion and analysis of our financial condition and results of operations
is based on our unaudited condensed consolidated financial statements, which
have been prepared in accordance with United States generally accepted
accounting principles. The preparation of these unaudited condensed consolidated
financial statements requires us to make estimates and assumptions that affect
the reported amounts of assets, liabilities, and the disclosure of contingent
assets and liabilities at the date of the unaudited condensed consolidated
financial statements, as well as revenue and expenses incurred during the
reporting periods. Our estimates are based on our historical experience and on
various other factors that we believe are reasonable under the circumstances,
the results of which form the basis for making judgments about the carrying
value of assets and liabilities that are not readily apparent from other
sources. Actual results may differ from these estimates under different
assumptions or conditions. We believe that the accounting policies discussed
below are critical to understanding our historical and future performance, as
these policies relate to the more significant areas involving management's
judgments and estimates.
There have been no significant changes in our critical accounting policies and
estimates as compared to the critical accounting policies and estimates
disclosed in the section titled "Management's Discussion and Analysis of
Financial Condition and Operations" included in our Annual Report on Form 10-K
for the fiscal year ended December 31, 2020.
Emerging Growth Company Status
We are an emerging growth company, as defined in the JOBS Act. Under the JOBS
Act, emerging growth companies can delay adopting new or revised accounting
standards issued subsequent to the enactment of the JOBS Act until such time as
those standards apply to private companies. Other exemptions and reduced
reporting requirements under the JOBS Act for emerging growth companies include
presentation of only two years audited financial statements in a registration
statement for an initial public offering, an exemption from the requirement to
provide an auditor's report on internal controls over financial reporting
pursuant to the Sarbanes-Oxley Act, an exemption from any requirement that may
be adopted by the Public Company Accounting Oversight Board regarding mandatory
audit firm rotation, and less extensive disclosure about our executive
compensation arrangements. We have elected to use the extended transition period
for complying with new or revised accounting standards that have different
effective dates for public and private companies until the earlier of the date
that (i) we are no longer an emerging growth company or (ii) we affirmatively
and irrevocably opt out of the extended transition period provided in the JOBS
Act. As a result, our condensed consolidated financial statements may not be
comparable to companies that comply with the new or revised accounting
pronouncements as of public company effective dates.
We will remain an emerging growth company under the JOBS Act until the earliest
of (i) the last day of our first fiscal year in which we have total annual gross
revenue of $1.07 billion or more, (ii) the date on which we have issued more
than $1.0 billion of non-convertible debt instruments during the previous three
fiscal years or (iii) the date on which we are deemed a "large accelerated
filer" under the rules of the SEC with at least $700.0 million of outstanding
equity securities held by non-affiliates, or (iv) the last day of the fiscal
year following the fifth anniversary of completion of our initial public
offering. We anticipate that we will no longer qualify as an emerging growth
company as of December 31, 2021 and expect to become a "large accelerated filer"
under the rules of the SEC with at least $700.0 million of outstanding equity
securities held by non-affiliates.

assessment, to the extent we have made one yet, of their potential impact on our
financial condition of results of operations.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
Interest Rate Risk
We have exposure to interest rate risk that relates to our cash, cash
equivalents, and investments held in money market funds and U.S. Treasury
securities. The goals of our investment policy are liquidity and capital
preservation. We believe that we do not have any material exposure to changes in
the fair value of these assets as a result of changes in interest rates due to
the short-term nature of our cash, cash equivalents, and investments.
Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Under the supervision and with the participation of our management, including
our Chief Executive Officer (CEO), and Chief Financial Officer (CFO), we
evaluated the effectiveness of the design and operation of our disclosure
controls and procedures pursuant to Rule 13a-15(e) and 15d-15(e) under the
Securities Exchange Act of 1934, as amended (the Exchange Act) as of the end of
the period covered by this report. Our disclosure controls and procedures are
designed to ensure that information required to be disclosed in the reports we
file or submit under the Exchange Act is recorded, processed, summarized and
reported within the time periods specified in the SEC's rules and forms, and
that such information is accumulated and communicated to our management,
including the CEO and the CFO, to allow timely decisions regarding required
disclosures. Any controls and procedures, no matter how well designed and
operated, can provide only reasonable assurance of achieving the desired control
objective and management necessarily applies its judgment in evaluating the
cost-benefit relationship of possible controls and procedures. Based on that
evaluation, our CEO and CFO have concluded that our disclosure controls and
procedures were not effective at a reasonable assurance level as of June 30,
2021 because of the material weakness in internal controls further discussed
below. Notwithstanding the material weakness, our management, including our CEO
and CFO, has concluded that our unaudited condensed consolidated financial
statements, included in this Quarterly Report fairly present, in all material
respects, our financial condition, results of operations and cash flows for the
periods presented in conformity with generally accepted accounting principles.
A material weakness is a deficiency, or a combination of deficiencies, in
internal control over financial reporting, such that a reasonable possibility
exists that a material misstatement of our annual or interim financial
statements would not be prevented or detected on a timely basis.
Specifically, our management determined that, as of June 30, 2021, we have
material weaknesses in each of the following components of the "Internal
Control-Integrated Framework" (2013), issued by the Committee of Sponsoring
Organizations of the Treadway Commission:
•insufficient accounting personnel to enable segregation of duties relating to
the general ledger,   disbursement, and certain accounting functions;
•no formalized processes or controls for account reconciliations, including
independent review of such reconciliations, or related financial statement
analysis prepared in conformity with generally accepted accounting principles in
the United States (U.S. GAAP); and
•an insufficient complement of accounting personnel with the necessary U.S. GAAP
technical expertise to timely identify and account for complex or non-routine
transactions or to formalize accounting policies, memoranda, or controls for
such transactions.
These material weaknesses could result in a misstatement of account balances or
disclosures that would result in a material misstatement of our annual or
interim consolidated financial statements that may not be prevented or detected,
and accordingly, it was determined that these control deficiencies constitute
material weaknesses.
Remediation Plan
                                       31
--------------------------------------------------------------------------------

We have begun to take certain actions to address the control deficiencies in our
financial reporting, including hiring three finance department employees with
appropriate expertise, including our Chief Financial Officer and our Controller,
and retaining an accounting consulting firm to provide additional depth and
breadth to our technical accounting and financial reporting capabilities. We
have also begun to review and document our accounting and financial processes
and internal controls, build out our financial management and reporting systems
infrastructure, and further develop and formalize our accounting policies and
financial reporting procedures, which includes ongoing senior management review
and establishing our audit committee oversight. In addition, we have commenced
work with a consulting firm to assist in the design effectiveness and testing of
our internal controls and we plan to hire an additional four finance and
accounting personnel during 2021 to assist in executing on these specific
functions, of which we have hired two personnel as of June 30, 2021.
Inherent Limitations on Effectiveness of Controls
Our management, including our CEO and CFO, does not expect that our disclosure
controls and procedures or our internal control over financial reporting will
prevent or detect all error and all fraud. A control system, no matter how well
designed and operated, can provide only reasonable, not absolute, assurance that
the control system's objectives will be met. The design of a control system must
reflect the fact that there are resource constraints, and the benefits of
controls must be considered relative to their costs. Further, because of the
inherent limitations in all control systems, no evaluation of controls can
provide absolute assurance that misstatements due to error or fraud will not
occur or that all control issues and instances of fraud, if any, within a
company have been detected. These inherent limitations include the realities
that judgments in decision-making can be faulty and that breakdowns can occur
because of simple error or mistake. Controls can also be circumvented by the
individual acts of some persons, by collusion of two or more people or by
management override of the controls. The design of any system of controls is
based in part on certain assumptions about the likelihood of future events, and
there can be no assurance that any design will succeed in achieving its stated
goals under all potential future conditions. Projections of any evaluation of
controls effectiveness to future periods are subject to risks. Over time,
controls may become inadequate because of changes in conditions or deterioration
in the degree of compliance with policies or procedures.
Changes in Internal Control over Financial Reporting
Except for the identification of the material weaknesses and the remediation
plan described above, there were no changes in our internal control over
financial reporting (as such term is defined in Rules 13a-15(f) under the
Exchange Act) during the quarter ended June 30, 2021 that has materially
affected, or is reasonably likely to materially affect, our internal control
over financial reporting.
