Overview



We design, develop and manufacture innovative, high-performance aerogel
insulation used primarily in the energy infrastructure and building materials
markets. We believe our aerogel blankets deliver the best thermal performance of
any widely used insulation product available on the market today and provide a
combination of performance attributes unmatched by traditional insulation
materials. Our end-use customers select our products where thermal performance
is critical and to save money, improve resource efficiency, enhance
sustainability, preserve operating assets and protect workers.

Our insulation is used by oil producers and the owners and operators of
refineries, petrochemical plants, liquefied natural gas facilities, power
generating assets and other energy infrastructure. Our Pyrogel and Cryogel
product lines have undergone rigorous technical validation by industry leading
end-users and achieved significant market adoption. We also derive product
revenue from the building materials and other end markets. Customers in these
markets use our products for applications as diverse as wall systems, military
and commercial aircraft, trains, buses, appliances, apparel, footwear and
outdoor gear. As we continue to enhance our aerogel technology platform, we
believe we will have opportunities to address additional high value applications
in the global insulation market and in a diverse set of new markets, including
the electric vehicle market.

We generate product revenue through the sale of our line of aerogel blankets. We market and sell our products primarily through a sales force based in North America, Europe and Asia. The efforts of our sales force are supported by a small number of sales consultants with extensive knowledge of a particular market or region. Our sales force is responsible for establishing and maintaining customer and partner relationships, delivering highly technical information and ensuring high-quality customer service.


                                       17

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


Our salespeople work directly with end-use customers and engineering firms to
promote the qualification, specification and acceptance of our products. We also
rely on an existing and well-established channel of qualified insulation
distributors and contractors in more than 50 countries around the world to
ensure rapid delivery of our products and strong end-user support. Our
salespeople also work to educate insulation contractors about the technical and
operating cost advantages of our aerogel blankets.

We also perform research services under contracts with various agencies of the
U.S. government, including the Department of Defense and the Department of
Energy, and other institutions. In late 2019, we decided to cease efforts to
secure additional funded research contracts and to wind down our existing
contract research activities during 2020. This decision reflected our desire to
focus our research and development resources on initiatives to improve the
profitability of our existing business and on efforts to develop new products
and next generation technology with application in new, high value markets.

We manufacture our products using our proprietary technology at our facility in
East Providence, Rhode Island. We have operated the East Providence facility
since 2008 and had increased our annual capacity through 2017 to 50 million
square feet of aerogel blankets. During 2018, we initiated a series of projects,
which we refer to as EP20, designed to increase this capacity to 60 million
square feet of aerogel blankets by the end of 2020. As of June 30, 2020, we had
increased our annual capacity to 55 million square feet of aerogel blankets as a
result of this initiative. We have delayed the implementation of our next
generation chemistry and process technologies during 2020 and currently expect
to achieve our EP20 goals by the end of 2021.

We are engaged in a strategic partnership with BASF to develop and commercialize
products for the building materials and other markets. The strategic partnership
includes a supply agreement governing the exclusive sale of specified products
to BASF and a joint development agreement targeting innovative products and
technologies. BASF has no obligation to purchase any products under the supply
agreement. Pursuant to the supply agreement, BASF may, in its sole discretion,
make prepayments to us in the aggregate amount of up to $22.0 million during the
term of the agreement. We may repay the prepayments to BASF at any time in whole
or in part for any reason.

BASF made a prepayment to us of $5.0 million during 2018. As of January 1, 2019,
25.3% of any amounts that we invoice for Spaceloft A2 sold to BASF will be
credited against the outstanding balance of the 2018 prepayment. If any amount
of the 2018 prepayment remains uncredited at December 31, 2021, BASF may require
that we repay the uncredited amount to BASF. In January 2019, BASF made an
additional prepayment to us of $5.0 million. As of January 1, 2020, 50% of any
amounts that we invoice for a newly developed product sold to BASF will be
credited against the outstanding balance of the 2019 prepayment. After December
31, 2022, BASF may require that we credit 24.7% of any amounts we invoice for
Spaceloft A2 sold to BASF against the outstanding balance of the 2019 prepayment
or may require that we repay the uncredited amount to BASF.

On February 18, 2020, we completed an underwritten public offering of 1,955,000
shares of our common stock at an offering price of $8.25 per share. We received
net proceeds of $14.8 million after deducting underwriting discounts and
commissions of $1.1 million and offering expenses of approximately $0.3
million.

On March 3, 2020, we amended our revolving credit facility with Silicon Valley
Bank to extend the maturity date of the facility to April 28, 2021. Under our
revolving credit facility, we are permitted to borrow a maximum of $20.0
million, subject to continued covenant compliance and borrowing base
requirements. At our election, the interest rate applicable to borrowings under
the revolving credit facility may be based on the prime rate or LIBOR. Prime
rate-based rates vary from prime rate plus 0.75% per annum to prime rate plus
2.00% per annum, while LIBOR-based rates vary from LIBOR plus 3.75% per annum to
LIBOR plus 4.25% per annum. In addition, we are required to pay a monthly unused
revolving line of credit facility fee of 0.5% per annum of the average unused
portion of the revolving credit facility. The credit facility was also amended
to establish certain minimum Adjusted EBITDA levels with respect to the minimum
Adjusted EBITDA financial covenant for the extended term. We currently project
that we may not meet the Adjusted EBITDA financial covenant for the quarter
ending on December 31, 2020. Accordingly, we intend to enter into discussions
with Silicon Valley Bank with the goal of modifying the Adjusted EBITDA
financial covenant to ensure continued compliance through the maturity of the
facility. We also intend to extend or replace the facility prior to its
maturity.

On May 1, 2020, our wholly-owned subsidiary, Aspen Aerogels Rhode Island, LLC
(Borrower), executed a note for an unsecured loan of $3,685,800 pursuant to the
Paycheck Protection Program (PPP Loan) under the Coronavirus Aid, Relief, and
Economic Security Act (CARES Act), as amended, and administered by the U.S.
Small Business Administration (SBA). The Borrower conferred with representatives
of the SBA prior to finalizing the PPP Loan. The loan is unsecured, contains
customary events of default, carries an interest rate of 1% per year, and
matures on May 1, 2022. The Borrower may repay the loan at any time without
penalty. In addition, the Borrower is permitted at any time to submit an
application to extend the maturity of loan to May 1, 2025.

The Borrower may apply to have the PPP Loan indebtedness forgiven in whole or in
part subject to SBA guidelines and based on the use of loan proceeds for payroll
costs, mortgage interest payments, rent and utility costs over either an
eight-week or 24-week

                                       18

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


period, at the Borrower's option, following its receipt of the loan proceeds.
The SBA may disapprove of the Borrower's loan forgiveness application if the
agency determines that it was ineligible for the PPP Loan. As of June 30, 2020,
the Borrower had not applied for forgiveness.

The Borrower is not required to apply for PPP loan forgiveness and, upon
application, it may not receive loan forgiveness in whole or in part. In
addition, the amount of potential loan forgiveness will be reduced if the
Borrower fails to maintain employee and salary levels during the eight-week or
24-week period following its receipt of the loan proceeds. If the Borrower
applies for forgiveness, and the PPP loan is not forgiven in whole or only
forgiven in part, the Borrower will be required to immediately begin making
payments of principal and accrued interest in equal monthly installments over
the remaining term of the loan for any post-forgiveness balance outstanding. If
the Borrower does not apply for forgiveness by August 19, 2021, it will be
required to make payments of principal and accrued interest in equal monthly
installments over the remaining term of the loan.

The Borrower is using the proceeds of the PPP loan to support ongoing operations
and to sustain staffing levels in our East Providence, Rhode Island
manufacturing facility despite the unfavorable impact the COVID-19 pandemic and
volatile energy markets are having on our business.

Our revenue for the six months ended June 30, 2020 was $53.1 million, which
represented a decrease of $4.4 million, or 8%, from the six months ended
June 30, 2019. Net loss for the six months ended June 30, 2020 was $8.9 million
and net loss per share was $0.34. Net loss for the six months ended June 30,
2019 was $11.3 million and net loss per share was $0.47.

With regard to the COVID-19 pandemic, we are following and implementing safe
practices recommended by public health authorities and other government
entities. We will continue to focus on the safety and health of our employees,
customers and vendors. We have implemented various precautionary measures,
including remote work arrangements, restricted business travel and procedures
for social distancing, face coverings and safe hygiene. We continue to monitor
public health guidance as it evolves and plan to adapt our practices as
appropriate. Refer to the section below entitled "Item 1A. Risk Factors" for
more information concerning risks to our business associated with COVID-19.

At present, we are not certain of the extent of the impact that the COVID-19
pandemic and global oil market volatility may have on our business. Our
manufacturing facility remains operational and we have not encountered any
significant disruption to our supply chain or our ability to deliver to our
customers. However, the demand for our products has been negatively impacted and
we expect to experience a year-over-year decrease in total revenue.

In response to this general uncertainty in the market for our products, we have
taken a number of actions to reduce expenses, including wage reductions,
temporary suspension of board fees and selected reductions to discretionary
expenses. In addition, as permitted by the CARES Act, we have elected to defer
certain payments of our employer share of Social Security tax that would
otherwise be required to be paid during the period beginning on March 27, 2020
and ending December 31, 2020. We are also prepared to temporarily curtail
operations in our East Providence, Rhode Island manufacturing facility if
necessary to ensure the safety of our employees or to align capacity with the
expected lower demand. However, these reductions and any subsequent actions we
may take may not be sufficient to offset the impact of the expected decrease in
revenue and we are likely to experience a year-over-year increase in net loss
and decrease in Adjusted EBITDA in 2020.

Key Metrics and Non-GAAP Financial Measures



We regularly review a number of metrics, including the following key metrics, to
evaluate our business, measure our performance, identify trends affecting our
business, formulate financial projections and make strategic decisions.

Square Foot Operating Metric



We price our product and measure our product shipments in square feet. We
estimate our annual capacity was 55 million square feet of aerogel blankets at
June 30, 2020. We believe the square foot operating metric allows us and our
investors to measure our manufacturing capacity and product shipments on a
uniform and consistent basis. The following chart sets forth product shipments
in square feet associated with recognized revenue, including revenue recognized
over time utilizing the input method, for the periods presented:



                                     Three Months Ended          Six Months Ended
                                          June 30,                   June 30,

                                       19

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





Adjusted EBITDA

We use Adjusted EBITDA, a non-GAAP financial measure, as a means to assess our
operating performance. We define Adjusted EBITDA as net income (loss) before
interest expense, taxes, depreciation, amortization, stock-based compensation
expense and other items, from time to time, which we do not believe are
indicative of our core operating performance. Adjusted EBITDA is a supplemental
measure of our performance that is not presented in accordance with U.S. GAAP.
Adjusted EBITDA should not be considered as an alternative to net income (loss)
or any other measure of financial performance calculated and presented in
accordance with U.S. GAAP. In addition, our definition and presentation of
Adjusted EBITDA may not be comparable to similarly titled measures presented by
other companies.

We use Adjusted EBITDA:

• as a measure of operating performance because it does not include the

impact of items that we do not consider indicative of our core operating

performance;

• for planning purposes, including the preparation of our annual operating


        budget;


    •   to allocate resources to enhance the financial performance of our
        business; and


  • as a performance measure used under our bonus plan.


We also believe that the presentation of Adjusted EBITDA provides useful
information to investors with respect to our results of operations and in
assessing the performance and value of our business. Various measures of EBITDA
are widely used by investors to measure a company's operating performance
without regard to items that can vary substantially from company to company
depending upon financing and accounting methods, book values of assets, capital
structures and the methods by which assets were acquired.

Although measures similar to Adjusted EBITDA are frequently used by investors
and securities analysts in their evaluation of companies, we understand that
Adjusted EBITDA has limitations as an analytical tool, and you should not
consider it in isolation or as a substitute for net income (loss), income (loss)
from operations, net cash provided by (used in) operating activities or an
analysis of our results of operations as reported under U.S. GAAP. Some of these
limitations are:

    •   Adjusted EBITDA does not reflect our historical cash expenditures or
        future requirements for capital expenditures or other contractual
        commitments;

• Adjusted EBITDA does not reflect changes in, or cash requirements for, our


        working capital needs;


  • Adjusted EBITDA does not reflect stock-based compensation expense;


    •   Adjusted EBITDA does not reflect our income tax expense or cash
        requirements to pay our income taxes;


    •   Adjusted EBITDA does not reflect our interest expense, or the cash
        requirements necessary to service interest or principal payments on our
        debt;

• although depreciation, amortization and impairment charges are non-cash

charges, the assets being depreciated, amortized or impaired will often

have to be replaced in the future, and Adjusted EBITDA does not reflect

any cash requirements for these replacements; and

• other companies in our industry may calculate EBITDA or Adjusted EBITDA

differently than we do, limiting their usefulness as a comparative

measure.




Because of these limitations, our Adjusted EBITDA should not be considered as a
measure of discretionary cash available to us to reinvest in the growth of our
business or as a measure of cash available for us to meet our obligations.

To properly and prudently evaluate our business, we encourage you to review the
U.S. GAAP financial statements included elsewhere in this Quarterly Report on
Form 10-Q, and not to rely on any single financial measure to evaluate our
business.



                                       20

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

The following table presents a reconciliation of net loss, the most directly comparable U.S. GAAP measure, to Adjusted EBITDA for the periods presented:

                 and modifications of stock option grants, vesting of restricted
                 stock units and vesting of restricted common stock.


Our financial performance, including such measures as net income (loss),
earnings per share and Adjusted EBITDA, are affected by a number of factors
including volume and mix of aerogel products sold, average selling prices, our
material and manufacturing costs, the costs associated with capacity expansions
and start-up of additional production capacity, and the amount and timing of
operating expenses. Accordingly, we expect that our net income (loss), earnings
per share and Adjusted EBITDA will vary from period to period.

Components of Our Results of Operations

Revenue



We recognize product revenue from the sale of our line of aerogel products and
research services revenue from the provision of services under contracts with
various agencies of the U.S. government and other institutions. Product and
research services revenue is recognized upon the satisfaction of contractual
performance obligations.

We record deferred revenue for product sales when (i) we have delivered products
but other revenue recognition criteria have not been satisfied or (ii) payments
have been received in advance of the completion of required performance
obligations.

At present, we are not certain of the extent of the impact that the COVID-19
pandemic and global oil market volatility may have on our business. Our
manufacturing facility remains operational and we have not yet encountered any
significant disruption to our supply chain or our ability to deliver to our
customers. However, the demand for our products has been negatively impacted and
we expect to experience a year-over-year decrease in total revenue.

Cost of Revenue

Cost of product revenue consists primarily of materials and manufacturing expense. Cost of product revenue is recorded when the related product revenue is recognized.



Material is our most significant component of cost of product revenue and
includes fibrous batting, silica materials and additives. Material costs as a
percentage of product revenue vary from product to product due to differences in
average selling prices, material requirements, product thicknesses and
manufacturing yields. In addition, we provide warranties for our products and
record the estimated cost within cost of revenue in the period that the related
revenue is recorded or when we become aware that a potential warranty claim is
probable and can be reasonably estimated. As a result of these factors, material
costs as a percentage of product revenue will vary from period to period due to
changes in the mix of aerogel products sold, the costs of our raw materials or
the estimated cost of warranties. We expect that material costs will decrease in
absolute dollars during 2020 due to the expected decrease in demand for our
products associated with the COVID-19 pandemic and global oil market volatility,
lower cost product formulations, and improved manufacturing yields.

Manufacturing expense is also a significant component of cost of revenue. Manufacturing expense includes labor, utilities, maintenance expense, and depreciation on manufacturing assets. Manufacturing expense also includes stock-based compensation of manufacturing employees and shipping costs. We expect that manufacturing expense will decline in absolute dollars during 2020 principally due to our plan to reduce compensation costs and discretionary expenses in response to the expected decrease in demand for our products associated with the COVID-19 pandemic and global oil market volatility.


                                       21

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

In total, we expect that cost of product revenue will decrease in absolute dollars during 2020, but is likely to increase as a percentage of product revenue versus 2019 due to the expected decrease in our 2020 revenue levels associated with the COVID-19 pandemic and global oil market volatility.



Cost of research services revenue consists of direct labor costs of research
personnel engaged in contract research, third-party consulting and subcontractor
expense, and associated direct material costs. This cost of revenue also
includes overhead expenses associated with project resources, development tools
and supplies. Cost of research services revenue is recorded when the related
research services revenue is recognized. We expect cost of research services
will decline as we wind down our existing contract research activities during
2020.

Gross Profit

Our gross profit as a percentage of revenue is affected by a number of factors,
including the volume of aerogel products produced and sold, the mix of aerogel
products sold, average selling prices, our material and manufacturing costs,
realized capacity utilization and the costs associated with expansions and
start-up of production capacity. Accordingly, we expect our gross profit in
absolute dollars and as a percentage of revenue to vary significantly from
period to period.

During 2020, the demand for our products has been negatively impacted due to the
COVID-19 pandemic and global oil market volatility and we expect to experience a
year-over-year decrease in total revenue. We also expect that material costs
will decrease as a result of lower cost product formulations, enhanced yields
and the expected decrease in demand for our products. In addition, we expect
that manufacturing expenses will decline principally due to our plan to reduce
compensation costs and discretionary expenses. However, we expect these material
cost and manufacturing reductions will not be sufficient to offset the impact of
the expected decrease in revenue and we are likely to experience a
year-over-year decrease in gross profit both in absolute dollars and as a
percentage of revenue during 2020.

Operating Expenses



Operating expenses consist of research and development, sales and marketing, and
general and administrative expenses. Operating expenses include personnel costs,
legal fees, professional fees, service fees, insurance premiums, travel expense,
facilities related costs and other costs and fees. The largest component of our
operating expenses is personnel costs, consisting of salaries, benefits,
incentive compensation and stock-based compensation. In any particular period,
the timing and extent of personnel additions or reductions, legal activities,
including patent enforcement actions, marketing programs, research efforts and a
range of similar activities or actions could materially affect our operating
expenses, both in absolute dollars and as a percentage of revenue.

We expect that operating expenses will decline in absolute dollars during 2020
principally due to our plan to reduce compensation costs and discretionary
expenses in response to the general uncertainty associated with the COVID-19
pandemic and global oil market volatility. However, we expect operating expenses
will increase as a percentage of revenue versus 2019 due to the expected
decrease in demand for our products during 2020.

Research and Development Expenses



Research and development expenses consist primarily of expenses for personnel
engaged in the development of next generation aerogel compositions, form factors
and manufacturing technologies. These expenses also include testing services,
prototype expenses, consulting services, trial formulations for new products,
equipment depreciation, facilities costs and related overhead. We expense
research and development costs as incurred. We expect to continue to devote
substantial resources to the development of new aerogel technologies. We believe
that these investments are necessary to maintain and improve our competitive
position. We expect to continue to invest in research and engineering personnel
and the infrastructure required in support of their efforts.

We expect that research and development expenses during 2020 will remain
unchanged from 2019 levels. However, we expect research and development expenses
to increase a percentage of revenue versus 2019 due to the expected decrease in
our revenue during 2020 as a result of the COVID-19 pandemic and global oil
market volatility and due to our decision to wind down our contract research
activities during 2020 to focus our research and development resources on
improving our existing business profitability and developing new products and
next generation technology with application in new, high value markets.

Sales and Marketing Expenses



Sales and marketing expenses consist primarily of personnel costs, incentive
compensation, marketing programs, travel and related costs, consulting expenses
and facilities related costs.

                                       22

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


We expect that sales and marketing expenses will decline in absolute dollars
during 2020 principally due to our plan to reduce compensation costs and
discretionary expenses in response to the general uncertainty associated with
the COVID-19 pandemic and global oil market volatility. However, we expect sales
and marketing expenses will increase as a percentage of revenue versus 2019 due
to the expected decrease in demand for our products during 2020.

General and Administrative Expenses



General and administrative expenses consist primarily of personnel costs, legal
expenses, consulting and professional services, audit and tax consulting costs,
and expenses for our executive, finance, legal, human resources and information
technology organizations. General and administrative expenses have increased as
we have incurred additional costs related to operating as a publicly-traded
company, which include costs of compliance with securities regulations,
corporate governance and related laws and regulations, investor relations
expenses, increased insurance premiums, including director and officer
insurance, and increased audit and legal fees. In addition, we expect our
general and administrative expenses to increase as we add general and
administrative personnel to support the anticipated growth of our business. We
also expect that the patent enforcement actions, described in more detail under
"Legal Proceedings" in Part II, Item 1 of this Quarterly Report on Form 10-Q, if
protracted, could result in significant legal expense over the medium to
long-term.

We expect that general and administrative expenses will decline in absolute
dollars during 2020 principally due to our plan to reduce compensation costs and
discretionary expenses in response to the general uncertainty associated with
the COVID-19 pandemic and global oil market volatility. However, we expect
general and administrative expenses will increase as a percentage of revenue
versus 2019 due to the expected decrease in demand for our products during 2020.

Interest Expense, Net

Interest expense, net consists primarily of fees and interest expense related to our revolving credit facility.

Provision for Income Taxes



We have incurred net losses since inception and have not recorded benefit
provisions for U.S. federal income taxes or state income taxes since the tax
benefits of our net losses have been offset by valuation allowances due to the
uncertainty associated with the utilization of net operating loss carryforwards.

Total revenue decreased $4.9 million, or 17%, to $24.6 million for the three
months ended June 30, 2020 from $29.5 million in the comparable period in 2019.
The decrease in total revenue was the result of decreases in both product
revenue and research services revenue.

Product revenue decreased by $4.4 million, or 15%, to $24.5 million for the
three months ended June 30, 2020 from $28.9 million in the comparable period in
2019. This decrease was principally the result of decreases in maintenance-based
demand in the U.S. petrochemical and refinery markets and in project-based
demand in the subsea market, offset, in part, by an increase in project-based
demand in the Asian LNG market.

Product revenue for the three months ended June 30, 2020 included $5.5 million
to an Asian LNG project contractor, $3.1 million to a subsea contractor and $2.4
million to a North American distributor. Product revenue for the three months
ended June 30, 2019 included $6.6 million to a subsea contractor, $4.3 million
to a North American distributor and $3.7 million to an Asian LNG project
contractor.

The average selling price per square foot of our products decreased by $0.08, or
2%, to $3.35 per square foot for the three months ended June 30, 2020 from $3.43
per square foot for the three months ended June 30, 2019. The decrease in
average selling price principally reflected the impact of the decrease in the
proportion of maintenance-based product revenue in the U.S. petrochemical and
refinery market for the three months ended June 30, 2020 from the comparable
period in 2019. This decrease in average selling price had the effect of
decreasing product revenue by $0.6 million for the three months ended June 30,
2020 from the comparable period in 2019.

In volume terms, product shipments decreased by 1.1 million square feet, or 13%,
to 7.3 million square feet of aerogel products for the three months ended
June 30, 2020, as compared to 8.4 million square feet for the three months ended
June 30, 2019. The decrease in product volume had the effect of decreasing
product revenue by $3.8 million for the three months ended June 30, 2020 from
the comparable period in 2019.

Research services revenue decreased $0.5 million, or 82%, to $0.1 million for
the three months ended June 30, 2020 from $0.6 million in the comparable period
in 2019. The decrease was primarily due to our decision to wind down our
contract research activities during 2020 to focus our research and development
resources on improving our existing business profitability and developing new
products and next generation technology with application in new, high value
markets.

Product revenue was nearly 100% of total revenue for the three months ended
June 30, 2020 and 98% of total revenue for the three months ended June 30, 2019.
Research services revenue was less than 1% of total revenue for the three months
ended June 30, 2020 and 2% of total revenue for the three months ended June 30,
2019.

Total cost of revenue decreased $4.2 million, or 16%, to $21.8 million for the
three months ended June 30, 2020 from $26.0 million in the comparable period in
2019. The decrease in total cost of revenue was the result of decreases in both
product cost of revenue and research services cost of revenue.

Product cost of revenue decreased by $3.9 million, or 15%, to $21.8 million for
the three months ended June 30, 2020 from $25.7 million in the comparable period
in 2019. The $3.9 million decrease was the result of a $2.2 million decrease in
material costs, and a $1.7 million decrease in manufacturing expense. The
decrease in material costs was the result of the 1.1 million square feet, or
13%, decrease in total product shipments, lower cost product formulations and
improved manufacturing yields. The decrease in manufacturing expense was the
result of decreases in compensation and related costs of $0.6 million,
maintenance expense of $0.3 million, operating supplies expense of $0.3 million,
waste disposal costs of $0.2 million, professional services expense of $0.2
million, and other manufacturing expenses of $0.1 million.

Product cost of revenue as a percentage of product revenue was 89% during both the three months ended June 30, 2020 and 2019.



Research services cost of revenue decreased $0.3 million, or 90%, to less than
$0.1 million for the three months ended June 30, 2020 from $0.3 million for the
comparable period in 2019. Cost of research service revenue as a percentage of
research services revenue decreased to 25% during the three months ended
June 30, 2020 from 49% in the comparable period in 2019 due to a decrease in the
proportion of third-party services utilized to support the contracted research.

Gross profit decreased by $0.7 million, or 19%, to $2.8 million for the three
months ended June 30, 2020 from $3.5 million in the comparable period in 2019.
The decrease in gross profit was the result of the $4.9 million decrease in
total revenue offset, in part, by the $4.2 million decrease in total cost of
revenue. The decrease in revenue was principally the result of decreases in
maintenance-based demand in the U.S. petrochemical and refinery markets and in
project-based demand in the subsea market, offset, in part, by an increase in
project-based demand in the Asian LNG market. The decrease in total cost of
revenue was the result of the 1.1 million square feet, or 13%, decrease in total
product shipments, lower cost product formulations, improved manufacturing
yields and a decrease in manufacturing expense.

Gross profit as a percentage of total revenue remained 12% of total revenue for the three months ended June 30, 2020 and 2019.

million for the three months ended June 30, 2020 from $1.9 million in the
comparable period in 2019. The $0.2 million increase was primarily the result of
an increase in compensation and related costs.

Research and development expenses as a percentage of total revenue increased to
9% for the three months ended June 30, 2020 from 6% in the comparable period in
2019 due to both the increase in research and development expenses and the
decrease in revenue during the three months ended June 30, 2020.

expense of $0.5 million and other marketing expenses of $0.2 million, offset, in
part, by increases in compensation and related costs of $0.1 million and sales
consultant expense of $0.1 million.

Sales and marketing expenses as a percentage of total revenue remained 12% of total revenue for the three months ended June 30, 2020 and 2019.

General and administrative expenses increased by $0.1 million, or 2%, to $3.4
million for the three months ended June 30, 2020 from $3.3 million in the
comparable period in 2019. The $0.1 million increase was the result of a
decrease in recoveries of provisions for uncollectible accounts receivable of
$0.2 million and an increase in compensation and related costs of $0.2 million,
offset, in part, by decreases in patent enforcement costs of $0.2 million and
other general and administrative costs of $0.1 million.

General and administrative expenses as a percentage of total revenue increased
to 14% for the three months ended June 30, 2020 from 11% in the comparable
period in 2019 due to both the increase in general and administrative expenses
and the decrease in revenue.

Total revenue decreased $4.4 million, or 8%, to $53.1 million for the six months
ended June 30, 2020 from $57.4 million in the comparable period in 2019. The
decrease in total revenue was the result of decreases in both product revenue
and research services revenue.

Product revenue decreased by $2.9 million, or 5%, to $52.8 million for the six
months ended June 30, 2020 from $55.7 million in the comparable period in 2019.
This decrease was principally the result of decreases in project-based demand in
the Canadian petrochemical and refinery markets, project-based demand in the
subsea market, and in maintenance-based demand in the U.S.

an Asian LNG project contractor and $9.4 million to a North American
distributor. Product revenue for the six months ended June 30, 2019 included
$10.0 million to a North American distributor and $6.8 million and $5.7 million
to two subsea contractors, respectively.

The average selling price per square foot of our products increased by $0.15, or
5%, to $3.41 per square foot for the six months ended June 30, 2020 from $3.26
per square foot for the six months ended June 30, 2019. The increase in average
selling price principally reflected the impact of price increases enacted in
2019 and 2020, offset, in part, by the impact of the decrease in the proportion
of maintenance-based product revenue in the U.S. petrochemical and refinery
market for the six months ended June 30, 2020 from the comparable period in
2019. This increase in average selling price had the effect of increasing
product revenue by $2.4 million for the six months ended June 30, 2020 from the
comparable period in 2019.

In volume terms, product shipments decreased by 1.6 million square feet, or 9%,
to 15.5 million square feet of aerogel products for the six months ended
June 30, 2020, as compared to 17.1 million square feet for the six months ended
June 30, 2019. The decrease in product volume had the effect of decreasing
product revenue by $5.3 million for the six months ended June 30, 2020 from the
comparable period in 2019.

Research services revenue decreased $1.5 million, or 87%, to $0.2 million for
the six months ended June 30, 2020 from $1.8 million in the comparable period in
2019. The decrease was primarily due to our decision to wind down our contract
research activities during 2020 to focus our research and development resources
on improving our existing business profitability and developing new products and
next generation technology with application in new, high value markets.

Product revenue was nearly 100% of total revenue for the six months ended
June 30, 2020 and 97% of total revenue for the six months ended June 30, 2019.
Research services revenue was less than 1% of total revenue for the six months
ended June 30, 2020 and 3% of total revenue for the six months ended June 30,
2019.

Total cost of revenue decreased $6.0 million, or 12%, to $44.2 million for the
six months ended June 30, 2020 from $50.2 million in the comparable period in
2019. The decrease in total cost of revenue was the result of decreases in both
product cost of revenue and research services cost of revenue.

Product cost of revenue decreased $5.0 million, or 10%, to $44.2 million for the
six months ended June 30, 2020 from $49.2 million in the comparable period in
2019. The $5.0 million decrease was the result of a $3.8 million decrease in
material costs and a $1.2 million decrease in manufacturing expense. The
decrease in material costs was driven principally by the 1.6 million square
feet, or 9%, decrease in product shipments, lower cost product formulations and
improved manufacturing yields. The decrease in manufacturing expense was the
result of decreases in operating supplies expenses of $0.4 million, waste
disposal costs of $0.2 million, maintenance expense of $0.2 million, utilities
expense of $0.2 million, compensation and related costs of $0.1 million, and
other manufacturing expenses of $0.1 million.

Product cost of revenue as a percentage of product revenue decreased to 84%
during the six months ended June 30, 2020 from 88% during the six months ended
June 30, 2019. This decrease was the result of price increases enacted in 2019
and 2020, a favorable mix of products sold, lower cost product formulations,
improved manufacturing yields and our initiatives to reduce manufacturing
expense.

Research services cost of revenue decreased $1.0 million, or 93%, to less than
$0.1 million for the six months ended June 30, 2020 from $1.0 million for the
comparable period in 2019. Cost of research service revenue as a percentage of

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


revenue decreased to 30% during the six months ended June 30, 2020 from 58% in
the comparable period in 2019 due to a decrease in the proportion of outside
services utilized to support the contracted research.

Gross profit increased $1.6 million, or 22%, to $8.8 million for the six months
ended June 30, 2020 from $7.2 million in the comparable period in 2019. The
increase in gross profit was the result of the $6.0 decrease in total cost of
revenue, offset, in part, by the $4.4 million decrease in total revenue. The
decrease in total cost of revenue was driven principally by the 1.6 million
square foot, or 9%, decrease in product shipments, lower cost product
formulations, improved manufacturing yields, and a decrease in manufacturing
expense. The decrease in revenue was principally associated with decreases in
project-based demand in the Canadian petrochemical and refinery markets,
project-based demand in the subsea market, and in maintenance-based demand in
the U.S. petrochemical and refinery markets, offset, in part, by an increase in
project-based demand in the Asian LNG market, and the impact of price increases
enacted in 2019 and 2020.

Gross profit as a percentage of total revenue increased to 17% of total revenue for the six months ended June 30, 2020 from 13% in the comparable period in 2019.

Research and development expenses increased by $0.5 million, or 15%, to $4.3
million for the six months ended June 30, 2020 from $3.8 million in the
comparable period in 2019. The $0.5 million increase was the result of increases
in compensation and related costs of $0.4 million and other research and
development expenses of $0.1 million.

Research and development expenses as a percentage of total revenue increased to
8% of for the six months ended June 30, 2020 from 7% in the comparable period in
2019 due to both the increase in research and development expenses and the
decrease in revenue.

Sales and marketing expenses decreased by $0.7 million, or 10%, to $6.3 million
for the six months ended June 30, 2020 from $7.0 million in the comparable
period in 2019. The $0.7 million decrease was the result of decreases in travel
expense of $0.6 million, compensation and related costs of $0.2 million and
other marketing expenses of $0.2 million, offset, in part, by an increase in
sales consultant expense of $0.3 million.

Sales and marketing expenses as a percentage of total revenue remained 12% for the six months ended June 30, 2020 and 2019.

General and administrative expenses decreased by $0.7 million, or 9%, to $6.9
million during the six months ended June 30, 2020 from $7.6 million in the
comparable period in 2019. The $0.7 million decrease was the result of decreases
in patent enforcement costs of $0.4 million, compensation and related costs of
$0.3 million, and other general and administrative expenses of $0.2 million,
offset, in part, by a decrease in recoveries of provisions for uncollectible
accounts receivable of $0.2 million.

Liquidity and Capital Resources

Overview



We have experienced significant losses and invested substantial resources since
our inception to develop, commercialize and protect our aerogel technology and
to build a manufacturing infrastructure capable of supplying aerogel products at
the volumes and costs required by our customers. These investments have included
research and development and other operating expenses, capital expenditures and
investment in working capital balances.

Through 2015, we experienced revenue growth and gained share in our target
markets. Despite a decline in revenue in 2016, 2017 and 2018, we experienced
strong growth in revenue, gross profit and cash flows from operations during
2019. Our financial projections anticipate long-term revenue growth, increasing
levels of gross profit and improved cash flow from operations. To support this
growth, we initiated a plan in 2018 to increase the capacity of our East
Providence, Rhode Island manufacturing facility to approximately 60 million
square feet of aerogel blankets by the end of 2020. We have delayed the
implementation of our next generation chemistry and process technologies during
2020 and currently expect to achieve our EP20 goals by the end of 2021. We may
incur additional capital expenditures to complete this plan during the remainder
of 2020 and 2021.

We have taken several actions to date in 2020 to increase the financial
resources available to support current operating requirements, capacity
expansions and strategic investments. In February 2020, we completed an
underwritten public offering of our common stock and received net proceeds of
$14.8 million. In March 2020, we extended the maturity of our revolving credit
facility with Silicon Valley Bank to April 28, 2021. Additionally, in May 2020,
our wholly-owned subsidiary, Aspen Aerogels Rhode Island, LLC, received PPP Loan
proceeds of $3.7 million under the CARES Act.

We believe that our existing cash balance will be sufficient to support
operations, complete the planned capacity expansion of our East Providence
manufacturing facility and to fund our planned strategic business initiatives.
However, we are not certain of the extent of the impact that the COVID-19
pandemic and global oil market volatility may have on our business. The demand
for our products has been negatively impacted and we expect to experience a
year-over-year decrease in total revenue.

In response to the expected decrease in demand for our products, we instituted a
number of actions to reduce expenses and to improve liquidity during the six
months ended June 30, 2020. However, these actions and any subsequent actions we
may take may not be sufficient to offset the impact of the expected decrease in
revenue and we are likely to experience a year-over-year increase in net loss, a
decrease in Adjusted EBITDA and an increase in cash used in operating activities
during 2020. In turn, we may not meet the Adjusted EBITDA financial covenant
under our revolving credit agreement with Silicon Valley Bank for the quarter
ending on December 31, 2020.

In response, we intend to enter into discussions with Silicon Valley Bank with
the objective of modifying the Adjusted EBITDA financial covenant to ensure
continued compliance through the maturity of the facility. We also intend to
extend or replace the facility prior to its maturity. We may also need to
supplement our cash balance with additional credit facilities, debt financings,
customer prepayments, technology licensing fees or equity financings to provide
the capital necessary to fund operating requirements, complete future capacity
expansions or to support evolving strategic business initiatives.

Primary Sources of Liquidity



Our principal sources of liquidity are currently our cash and cash equivalents
and our revolving credit facility with Silicon Valley Bank. Cash and cash
equivalents consist primarily of cash and money market accounts on deposit with
banks. As of June 30, 2020, we had $13.4 million of cash and cash equivalents.

On February 18, 2020, we completed an underwritten public offering of 1,955,000
shares of our common stock at an offering price of $8.25 per share. We received
net proceeds of $14.8 million after deducting underwriting discounts and
commissions of $1.1 million and offering expenses of approximately $0.3
million.

On May 1, 2020, the Borrower executed a note for an unsecured loan of $3,685,800
pursuant to the PPP under the CARES Act, as amended, and administered by the
SBA. The loan is unsecured, contains customary events of default, carries an
interest rate of 1% per year, and matures on May 1, 2022. The Borrower may repay
the loan in full at any time without penalty. In addition, the Borrower is
permitted at any time to submit an application to extend the maturity of loan to
May 1, 2025.

The Borrower may apply to have the PPP Loan indebtedness forgiven in whole or in
part subject to SBA guidelines and based on the use of loan proceeds for payroll
costs, mortgage interest payments, rent and utility costs over either an
eight-week or 24-week period, at the Borrower's option, following its receipt of
the loan proceeds. The SBA may disapprove of the Borrower's loan forgiveness
application if the agency determines that it was ineligible for the PPP Loan. As
of June 30, 2020, the Borrower had not applied for forgiveness.

The Borrower is not required to apply for PPP loan forgiveness and, upon
application, it may not receive loan forgiveness in whole or in part. In
addition, the amount of potential loan forgiveness will be reduced if the
Borrower fails to maintain employee and certain salary levels during the
eight-week or 24-week period following its receipt of the loan proceeds. If the
Borrower applies for forgiveness, and the PPP loan is not forgiven in whole or
only forgiven in part, it will be required to immediately begin making payments
of principal and accrued interest in equal monthly installments over the
remaining term of the loan for any post-forgiveness balance outstanding. If the
Borrower does not apply for forgiveness by August 19, 2021, it will be required
to make payments of principal and accrued interest in equal monthly installments
over the remaining term of the loan.

The Borrower is using the proceeds of the PPP loan to support ongoing operations
and to sustain staffing levels in our East Providence, Rhode Island
manufacturing facility despite the unfavorable impact the COVID-19 pandemic and
volatile energy markets are having on our business.

At June 30, 2020, we had no outstanding borrowings under our revolving credit
facility with Silicon Valley Bank, $1.3 million of outstanding letters of credit
secured by the revolving credit facility, $3.7 million outstanding on the PPP
Loan, and an obligation of $9.9 million associated with prepayments received
pursuant to our supply agreement with BASF.

We have maintained the revolving credit facility, as amended from time to time,
with Silicon Valley Bank since March 2011. On March 3, 2020, our revolving
credit facility was amended to extend the maturity date of the facility to April
28, 2021. The amendment to the credit facility also established certain minimum
Adjusted EBITDA levels with respect to the minimum Adjusted EBITDA financial
covenant for the extended term.

Under our revolving credit facility, we are permitted to borrow a maximum of
$20.0 million, subject to continued covenant compliance and borrowing base
requirements. At our election, the interest rate applicable to borrowings under
the revolving credit facility may be based on the prime rate or LIBOR. Prime
rate-based rates vary from prime rate plus 0.75% per annum to prime rate plus
2.00% per annum, while LIBOR-based rates vary from LIBOR plus 3.75% per annum to
LIBOR plus 4.25% per annum. In addition, we are required to pay a monthly unused
revolving line of credit facility fee of 0.5% per annum of the average unused
portion of the revolving credit facility.

Under the revolving credit facility, we are required to comply with both
non-financial and financial covenants, including the minimum Adjusted EBITDA
covenant, as defined in the loan agreement. At June 30, 2020, we were in
compliance with all such covenants. However, we currently project that we may
not meet the Adjusted EBITDA financial covenant for the quarter ending on
December 31, 2020. Accordingly, we intend to enter into discussions with Silicon
Valley Bank with the goal of modifying the Adjusted EBITDA financial covenant to
ensure continued compliance through the maturity of the facility. We also intend
to extend or replace the facility prior to its maturity.

The amount available to us under the facility at June 30, 2020 was $8.9 million after giving effect to the $1.3 million of letters of credit outstanding.

Analysis of Cash Flow

Net Cash Used in Operating Activities



During the six months ended June 30, 2020, we used $3.2 million in net cash in
operating activities, as compared to the use of $1.9 million in net cash during
the comparable period in 2019, an increase in the use of cash of $1.3 million.
This increase in use of cash was the result of an increase in net cash used by
changes in operating assets and liabilities of $3.9 million, offset, in part, by
a decrease in net loss adjusted for non-cash items of $2.6 million.

Net Cash Used in Investing Activities



Net cash used in investing activities is primarily related to capital
expenditures to support our growth. Net cash used in investing activities for
the six months ended June 30, 2020 and 2019 was $2.0 million and $1.3 million,
respectively, in capital expenditures primarily for machinery and equipment to
improve the capacity, throughput, efficiency and reliability of our East
Providence facility.

Net Cash Provided by Financing Activities



Net cash provided by financing activities for the six months ended June 30, 2020
totaled $14.9 million and consisted of $19.4 million in borrowings under our
line of credit, $14.8 million in net proceeds from an underwritten public
offering of our common stock, $3.7 million in net proceeds from the issuance of
long-term debt, and $0.9 million in proceeds from employee stock option
exercises, offset, in part, by $22.6 million of repayments under our line of

Recent Accounting Pronouncements

Information regarding new accounting pronouncements is included in note 2 to our unaudited consolidated financial statements contained in Item 1 of this Quarterly Report on Form 10-Q.

Critical Accounting Policies and Estimates



Our financial statements are prepared in accordance with U.S. GAAP. The
preparation of our financial statements and related disclosures requires us to
make estimates, assumptions and judgments that affect the reported amount of
assets, liabilities, revenue, costs and expenses and related disclosures. We
believe that the estimates, assumptions and judgments involved in these
accounting policies have the greatest potential impact on our financial
statements and, therefore, we consider these to be our critical accounting
policies. Accordingly, we evaluate our estimates and assumptions on an ongoing
basis. Our actual results may differ from these estimates under different
assumptions and conditions. See our Annual Report and note 2 to our consolidated
financial statements included elsewhere in this Quarterly Report on Form 10-Q
for information about these critical accounting policies, as well as a
description of our other significant accounting policies.

Certain Factors That May Affect Future Results of Operations



The SEC encourages companies to disclose forward-looking information so that
investors can better understand a company's future prospects and make informed
investment decisions. This Quarterly Report on Form 10-Q contains such
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. These statements involve known and unknown risks,
uncertainties and other important factors which may cause our actual results,
performance or achievements to be materially different from any future results,
performances or achievements expressed or implied by the forward-looking
statements.
