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.


                                       16

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


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 market
segments.

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 March 31, 2020, we had
increased our annual capacity to 55 million square feet of aerogel blankets as a
result of this initiative and believe we are on track to achieve our EP20 goals
by the end of 2020.

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 has also been
amended to establish certain minimum Adjusted EBITDA levels with respect to the
minimum Adjusted EBITDA financial covenant for the extended term. We intend to
extend or replace the facility prior to its maturity.

Our revenue for the three months ended March 31, 2020 was $28.4 million, which
represented an increase of $0.5 million, or 2%, from the three months ended
March 31, 2019. Net loss for the three months ended March 31, 2020 was $3.2
million and net loss per share was $0.13. Net loss for the three months ended
March 31, 2019 was $6.0 million and net loss per share was $0.25.

At present, we are not certain of the extent of the impact that the COVID-19
pandemic and the 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 Coronavirus Aid, Relief and Economic
Security Act (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

                                       17

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


ending December 31, 2020. The CARES Act allows employers to deposit 50 percent
of the deferred taxes on or before December 31, 2021, and the remaining 50
percent by December 31, 2022. 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
March 31, 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
                                                        March 31,
                                                    2020          2019
                                                    (In thousands)
              Product shipments in square feet        8,165        8,685




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;


                                       18

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



  • 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.

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





                                                 Three Months Ended

               Adjusted EBITDA                 $      469     $ (2,551 )




             (1) Represents non-cash stock-based compensation related to vesting
                 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, including patent enforcement costs. 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 the 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.

                                       19

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

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 as we implement lower cost product formulations,
seek enhanced yields and potentially as a result of any decrease in demand for
our products associated with the COVID-19 pandemic and the global oil market
volatility.

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 general uncertainty in demand for our products associated with the COVID-19 pandemic and the global oil market volatility.

In total, we expect that cost of product revenue will decrease in absolute dollars during 2020, but may either increase or decrease as a percentage of product revenue versus 2019 due to uncertainty in our 2020 revenue levels associated with the COVID-19 pandemic and the 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 the 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 potentially due to any 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,
these material cost and manufacturing reductions may 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 in demand for our products associated with the COVID-19 pandemic and the global oil market volatility. However, operating expenses may either increase or decrease as a


                                       20

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

percentage of revenue versus 2019 due to the uncertain impact that the COVID-19 pandemic and the global oil market volatility may have on our 2020 revenue levels.

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 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 in demand for our
products. However, research and development expenses may either increase or
decrease as a percentage of revenue versus 2019 due to the uncertain impact that
the COVID-19 pandemic and the global oil market volatility may have on our 2020
revenue levels.

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.

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 in demand for our
products. However, sales and marketing expenses may either increase or decrease
as a percentage of revenue versus 2019 due to the uncertain impact that the
COVID-19 pandemic and the global oil market volatility may have on our 2020
revenue levels.

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 in demand for our
products. However, general and administrative expenses may either increase or
decrease as a percentage of revenue versus 2019 due to the uncertain impact that
the COVID-19 pandemic and the global oil market volatility may have on our 2020
revenue levels.

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 increased $0.5 million, or 2%, to $28.4 million for the three
months ended March 31, 2020 from $27.9 million in the comparable period in 2019
as a result of an increase in product revenue, offset, in part, by a decrease in
research services revenue.

Product revenue increased by $1.5 million, or 6%, to $28.3 million for the three
months ended March 31, 2020 from $26.8 million in the comparable period in 2019.
This increase was principally the result of growth in the US petrochemical and
refinery markets, an increase in project-based demand in the LNG market, the
impact of price increases enacted in 2019 and 2020, and a favorable mix of
products sold, offset, in part, by decreases in project-based demand in the
subsea market and the Canadian petrochemical and refinery market.

Product revenue for the three months ended March 31, 2020 included $7.0 million
to a North American distributor and $4.6 million to an Asian LNG project
contractor. Product revenue for the three months ended March 31, 2019 included
$5.6 million to a North American distributor and $4.5 million to a European
subsea contractor.

The average selling price per square foot of our products increased by $0.39, or
13%, to $3.47 per square foot for the three months ended March 31, 2020 from
$3.08 per square foot for the three months ended March 31, 2019. The increase in
average selling price principally reflected the impact of price increases
enacted in 2019 and 2020. This increase in average selling price had the effect
of increasing product revenue by $3.1 million for the three months ended
March 31, 2020 from the comparable period in 2019.

In volume terms, product shipments decreased by 0.5 million square feet, or 6%,
to 8.2 million square feet of aerogel products for the three months ended
March 31, 2020, as compared to 8.7 million square feet for the three months
ended March 31, 2019. The decrease in product volume had the effect of
decreasing product revenue by $1.6 million for the three months ended March 31,
2020 from the comparable period in 2019.

Research services revenue decreased $1.0 million, or 90%, to $0.1 million for
the three months ended March 31, 2020 from $1.1 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 on developing new
products and next generation technology with application in new, high value
market segments.

Product revenue was nearly 100% of total revenue for the three months ended
March 31, 2020 and 96% of total revenue for the three months ended March 31,
2019. Research services revenue was less than 1% of total revenue for the three
months ended March 31, 2020 and 4% of total revenue for the three months ended
March 31, 2019.

Total cost of revenue decreased $1.8 million, or 7%, to $22.4 million for the
three months ended March 31, 2020 from $24.2 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 by $1.1 million, or 5%, to $22.4 million for
the three months ended March 31, 2020 from $23.5 million in the comparable
period in 2019. The $1.1 million decrease was the result of a $1.5 million
decrease in material costs, offset, in part, by a $0.4 million increase in
manufacturing expense. The decrease in material costs was the result of the
0.5 million square feet, or 6%, decrease in total product shipments, the impact
of lower cost product formulations and material purchasing efficiencies, and a
favorable mix of products sold. The increase in manufacturing expense was the
result of increases in compensation and related costs of $0.4 million,
maintenance expense of $0.1 million, and other manufacturing expenses of $0.1
million, offset, in part, by a decrease in utilities expense of $0.2 million.

Product cost of revenue as a percentage of product revenue decreased to 79%
during the three months ended March 31, 2020 from 88% during the three months
ended March 31, 2019. This decrease was driven by both the decrease in product
cost of revenue and the increase in product revenue during the three months
ended March 31, 2020.

Research services cost of revenue decreased $0.7 million, or 94%, to less than
$0.1 million for the three months ended March 31, 2020 from $0.7 million for the
comparable period in 2019. Cost of research service revenue as a percentage of
research services revenue decreased to 36% during the three months ended
March 31, 2020 from 64% 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 increased by $2.3 million, or 61%, to $6.0 million for the three
months ended March 31, 2020 from $3.7 million in the comparable period in 2019.
The increase in gross profit was the result of the $0.5 million increase in
total revenue and the $1.8 million decrease in total cost of revenue. The
increase in revenue was principally associated with growth in the US
petrochemical and refinery markets, an increase in project-based demand in the
LNG market, the impact of price increases enacted in 2019 and 2020, and a
favorable mix of products sold, offset, in part, by decreases in project-based
demand in the subsea market and the Canadian petrochemical and refinery markets.
The decrease in total cost of revenue was the result of the 0.5 million square

Gross profit as a percentage of total revenue increased to 21% of total revenue
for the three months ended March 31, 2020 from 13% in the comparable period in
2019.

Research and development expenses increased by $0.3 million, or 16%, to $2.2
million for the three months ended March 31, 2020 from $1.9 million in the
comparable period in 2019. The $0.3 million increase was the result of increases
in compensation and related costs of $0.2 million and other research and
development costs of $0.1 million.

Research and development expenses as a percentage of total revenue increased to
8% for the three months ended March 31, 2020 from 7% in the comparable period in
2019 due to the increase in research and development expenses, offset, in part,
by the increase in revenue during the three months ended March 31, 2020.

Sales and marketing expenses decreased by $0.2 million, or 5%, to $3.3 million
from $3.5 million in the comparable period in 2019. The $0.2 million decrease
was the result of decreases in compensation and related costs of $0.3 million
and travel expense of $0.1 million, offset, in part, by an increase in sales
consultant expense of $0.2 million.

Sales and marketing expenses as a percentage of total revenue decreased to 12%
for the three months ended March 31, 2020 from 13% in the comparable period in
2019 due to both the decrease in sales and marketing expenses and the increase
in revenue.

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 may incur additional
capital expenditures to complete this plan during 2020.

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. On May 1, 2020, our
subsidiary, Aspen Aerogels Rhode Island, LLC, executed a promissory note to
receive loan proceeds of approximately $3.7 million under the Paycheck
Protection Program (PPP) of the CARES Act.

We believe that our existing cash balance, expected PPP loan proceeds, and
available credit 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 the 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 general uncertainty in demand for our products, we instituted
a number of actions to reduce expenses and to improve liquidity during the first
quarter and April 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.

As a result, we may need to supplement our cash balance, expected PPP loan proceeds, and available credit with additional 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 March 31, 2020, we had $11.8 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, our wholly-owned subsidiary, Aspen Aerogels Rhode Island, LLC,
secured a PPP loan established as part of the CARES Act for the principal amount
of approximately $3.7 million. The PPP loan and related accrued interest may be
forgivable after eight weeks by application to the PPP lender provided that the
subsidiary maintain the payroll level and use the loan proceeds for eligible
purposes, including payroll, benefits, rent, and utilities of the subsidiary.
The amount of loan forgiveness will be reduced if the subsidiary does not
maintain the number of employees or reduce their salaries below certain levels
during the eight-week period. The

                                       25

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


PPP loan is payable over two years at an interest rate of 1%, with a deferral of
payments for the first six months. Our subsidiary intends to use the proceeds
for purposes consistent with the PPP and we believe that our subsidiary's use of
the loan proceeds will meet the conditions for forgiveness of at least a portion
of the loan.

At March 31, 2020, we had no outstanding borrowings under our revolving credit
facility with Silicon Valley Bank, $1.2 million of outstanding letters of credit
secured by the revolving credit facility 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. We intend to extend or replace the
facility prior to its maturity.

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 March 31, 2020, we were in compliance with all such covenants.

The amount available to us under the facility at March 31, 2020 was $8.8 million after giving effect to the $1.2 million of letters of credit outstanding.

Analysis of Cash Flow

Net Cash Used in Operating Activities



During the three months ended March 31, 2020, we used $1.4 million in net cash
in operating activities, as compared to the use of $3.0 million in net cash
during the comparable period in 2019, a decrease in the use of cash of $1.6
million. This decrease in use of cash was the result of a decrease in net loss
adjusted for non-cash items of $3.0 million, offset, in part, by an increase in
cash used by changes in operating assets and liabilities of $1.4 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 three months ended March 31, 2020 and 2019 was $0.9 million and $0.6
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 three months ended March 31,
2020 totaled $10.4 million and consisted of $19.4 million in borrowings under
our line of credit and $14.8 million in net proceeds from an underwritten public
offering of our common stock, offset, in part, by $22.6 million of repayments
under our line of credit and $1.2 million in cash used for payments made for
employee tax withholdings associated with the vesting of restricted stock units.

Net cash provided by financing activities for the three months ended March 31,

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.
