Business Overview

EMCORE Corporation (referred to herein, together with its subsidiaries, as the
"Company," "we," "our," or "EMCORE") was established in 1984 as a New Jersey
corporation. We became publicly traded in 1997 and are listed on the Nasdaq
Stock Exchange under the ticker symbol EMKR. We are a leading provider of
sensors for navigation in the Aerospace and Defense market as well as a
manufacturer of lasers and optical subsystems for use in the Cable TV ("CATV")
industry.

We pioneered the linear fiber optic transmission technology that enabled the
world's first delivery of CATV directly on fiber, and today is a leading
provider of advanced Mixed-Signal Optics products serving the broadband
communications and Aerospace and Defense markets. The Mixed-Signal Optics
technology at the heart of our broadband communications products is shared with
our fiber optic gyros and inertial sensors to provide the aerospace and defense
markets with state-of-the-art navigations systems technology. With the
acquisition of Systron Donner Inertial, Inc. ("SDI"), a navigation systems
provider with a scalable, chip-based platform for higher volume gyro
applications utilizing Quartz MEMS technology, in June 2019, we further expanded
our portfolio of gyros and inertial sensors with SDI's quartz MEMS gyro and
accelerometer technology.

We have fully vertically-integrated manufacturing capability through our indium
phosphide compound semiconductor wafer fabrication facility at our headquarters
in Alhambra, CA, and through our quartz processing and sensor manufacturing
facility in Concord, CA. These facilities support our vertically-integrated
manufacturing strategy for quartz and fiber optic gyro products, for navigation
systems, and for our chip, laser, transmitter, and receiver products for
broadband applications.

We have two reporting segments, Aerospace and Defense, and Broadband. Aerospace
and Defense is comprised of two product lines: (i) Navigation and Inertial
Sensing, and (ii) Defense Optoelectronics. The Broadband segment is comprised of
three product lines: (i) CATV Lasers and Transmitters, (ii) Chip Devices, and
(iii) Other. Due to a shift in customer base, the previously existing
Satellite/Microwave Communications product line has been renamed "Defense
Optoelectronics."

Recent Developments

COVID-19

The global outbreak of the coronavirus disease 2019 ("COVID-19") was declared a
pandemic by the World Health Organization and a national emergency by the U.S.
Government in March 2020. The COVID-19 pandemic has negatively affected the U.S.
and global economy, disrupted global supply chains, significantly restricted
travel and transportation, resulted in mandated closures and orders to
"shelter-in-place," and created significant disruption of the financial markets.
The full extent of the COVID-19 impact on our operational and financial
performance will depend on future developments, including the duration and
spread of the pandemic and related actions taken by the U.S. government, state
and local government officials, and international governments to prevent disease
spread, all of which are uncertain, out of our control, and cannot be predicted.

Each region we and our supply chain partners operate in has been affected by
COVID-19 at varying times and magnitudes, often creating unforeseen challenges
associated with logistics, raw material supply and labor shortages. In
accordance with applicable U.S. state and county ordinances generally exempting
essential businesses and/or critical infrastructure workforces from mandated
closures and orders to "shelter-in-place," our U.S. production facilities have

                                       48

  Table of Contents

continued to operate in support of essential products and services, subject to
limitations and requirements pursuant to applicable state and county orders with
regard to ongoing operations that have reduced the efficiency of our engineering
and operational teams. While operations at our facility in China were delayed in
early February 2020, we were at planned capacity by the end of February and
throughout the quarters ended June 30 and September 30, 2020.

We rely on third party suppliers and contract manufacturers to provide
materials, major components and products, and services. Many of our suppliers
have at times temporarily ceased or limited operations as a result of COVID-19
and failed to deliver parts or components to us. For example, in the quarter
ended June 30, 2020, unexpected delays and cancellations of key component
deliveries caused disruption to our business, and these actions may continue in
the future. In addition, the decline in commercial airline traffic has at times
created shortages in air freight capacity, making it more difficult and costly
to timely procure parts and components.

We remain diligent in continuing to identify and manage risks to our business
given the changing uncertainties related to COVID-19 and have plans in place
intended to address or mitigate shortages of labor, material supplies and
logistics services. While we believe that our supply chain, logistics and
operations teams are currently in a position to meet expected customer demand
levels in the coming quarters, we recognize that unpredictable events could
create new challenges in the months ahead. We may not be able to address these
challenges in a timely manner, which could negatively impact our financial
results.

In addition, restrictions related to the COVID-19 pandemic have negatively
affected the timing of the sale and transfer of certain CATV module and
transmitter manufacturing equipment to the Buyers (defined below), as described
in more detail below under "Hytera Transactions". Travel into Thailand by our
manufacturing engineers to support the transfer remains difficult, and customer
product qualification processes for products being manufactured in Thailand are
being delayed due to our customers' inability to access their facilities to
perform testing. While we are taking actions within our supply chain and
manufacturing operations to mitigate the effects of these delays, the timing and
completion of these transfers may be further disrupted as a result of COVID-19,
which could delay our recognition of the anticipated benefits of transferring
this equipment and could disrupt our manufacturing activities for these
products.

Our customer orders to date have generally remained stable with our pre-COVID-19
outlook, except with respect to customer orders related to the CATV Lasers and
Transmitters product line, which have increased compared to our pre-COVID-19
outlook. However, qualification testing for certain of our products has been
delayed due to customer engineering shortages and limitations on their ability
to access their facilities, and development timelines for certain programs are
being extended. We continue to analyze on an ongoing basis how COVID-19 related
actions could affect our product development efforts, future customer demand,
timing of orders, recognized revenues, and cash flows.

The continued spread of COVID-19 has also led to disruption and volatility in
the global capital markets, which, depending on future developments, could
impact our capital resources and liquidity in the future. If we need to raise
additional capital to support operations in the future, we may be unable to
access capital markets and additional capital may only be available to us on
terms that could be significantly detrimental to our existing stockholders and
to our business as a result of COVID-19.

SDI Acquisition



On June 7, 2019, we completed the acquisition of SDI, a private-equity backed
navigation systems provider with a scalable, chip-based platform for higher
volume gyro applications utilizing Quartz MEMS technology. See   Note 4 -
Acquisition   in the notes to our consolidated financial statements for
additional information regarding this acquisition. Following the closing, we
began integrating SDI into our current Navigation and Inertial Sensing product
line and have included the financial results of SDI in our consolidated
financial statements beginning on the acquisition date.

Hytera Transactions


As part of the effort to streamline operations and move to a variable cost model
in our CATV Lasers and Transmitters product line, on October 25, 2019, we
entered into an Asset Purchase Agreement (the "Asset Purchase Agreement") with
Hytera Communications (Hong Kong) Company Limited, a limited liability company
incorporated in Hong Kong

                                       49

  Table of Contents

("Hytera HK"), and Shenzhen Hytera Communications Co., Ltd., a corporation
formed under the laws of the P.R.C. ("Shenzhen Hytera", and together with Hytera
HK, the "Buyers"), pursuant to which the Buyers agreed to purchase from EMCORE
certain CATV module and transmitter manufacturing equipment (the "Equipment")
owned by EMCORE and currently located at the manufacturing facility of our
wholly-owned subsidiary, EMCORE Optoelectronics (Beijing) Co, Ltd., a
corporation formed under the laws of the P.R.C., for an aggregate purchase price
of approximately $5.54 million.

As described under "COVID-19" above, travel restrictions and delays in customer
product qualification processes related to the COVID-19 pandemic have negatively
affected the timing of the sale and transfer of some of the Equipment to the
Buyers. The Equipment has been or will be transferred to the Buyers in three
separate closings, (a) one of which occurred in the quarter ended December 31,
2019, with aggregate payments in an amount equal to approximately $2.3 million
received in such quarter, (b) one of which is now expected to occur during the
quarter ending March 31, 2021, for which 80% of the applicable sale price
(approximately $1.4 million) was received in April 2020 and the remaining 20%
(approximately $0.4 million) is expected to be received in the quarter ending
March 31, 2021, and (c) one of which is now expected to occur during the quarter
ending June 30, 2021, with payment expected to be received in the quarter ending
June 30, 2021.

Concurrently with entry into the Asset Purchase Agreement, we entered into a
Contract Manufacturing Agreement (the "Manufacturing Agreement"), dated as of
October 25, 2019, with the Buyers pursuant to which the Buyers agreed to
manufacture certain CATV module and transmitter products for us from a
manufacturing facility located in Thailand for an initial five year term at
product prices agreed to between the parties. In the Manufacturing Agreement, we
agreed to pay certain shortfall penalties in the event that orders for
manufactured products are below certain thresholds.

Other Actions Related to CATV Business



In the quarter ended September 30, 2019, we also reduced the size of our
CATV-related employee headcount and reduced the capacity of our wafer fab to one
shift, and in January 2020, we further reduced the size of our employee
headcount. These actions incurred costs of $0.4 million in the quarter ended
September 30, 2019 and $0.4 million in the quarter ended March 31, 2020 and,
together with previously-disclosed headcount reduction at our Beijing, China
facility and the continuing shift to a variable cost model in our CATV Lasers
and Transmitters product line as described under "Hytera Transactions" above,
have collectively resulted in annual cash savings of approximately $3.4 million
beginning in the quarter ended March 31, 2020 and continuing through the quarter
ended September 30, 2020. These operational changes in CATV also fulfill a
strategic objective of better positioning the CATV Lasers and Transmitters
product line to generate positive cash flow to help fund our growth areas
including Aerospace and Defense.

Sale/Leaseback Transaction



SDI entered into a Standard Offer, Agreement and Escrow Instructions for
Purchase of Real Estate (Non-Residential) (the "Concord Purchase Agreement")
dated as of December 31, 2019 with Parkview Management Group, Inc. pursuant to
which the parties agreed to consummate a sale and leaseback transaction (the
"Sale and Leaseback Transaction"). Under the terms of the Concord Purchase
Agreement, SDI sold the property located in Concord, California (the "Concord
Real Property") to Eagle Rock Holdings, LP ("Buyer"), an affiliate of Parkview
Management Group, Inc. on February 10, 2020 for a total purchase price of $13.2
million. SDI received net proceeds of $12.8 million after transaction
commissions and expenses incurred in connection with the sale.

At the consummation of the Sale and Leaseback Transaction, SDI entered into a
Single-Tenant Triple Net Lease (the "Lease Agreement") with Buyer pursuant to
which SDI leased back from Buyer the Concord Real Property for a term commencing
on the consummation of the Sale and Leaseback Transaction and ending fifteen
(15) years after the consummation of the Sale and Leaseback Transaction, unless
earlier terminated or extended in accordance with the terms of the Lease
Agreement. Under the Lease Agreement, SDI's financial obligations will include
base monthly rent of $0.75 per square foot, or approximately $77,500 per month,
which rent will increase on an annual basis at three percent (3%) over the life
of the lease. SDI is also responsible for all monthly expenses related to the
Concord Real Property, including insurance premiums, taxes and other expenses,
such as utilities. In connection with the execution of the Lease Agreement,
EMCORE executed a Lease Guaranty with Buyer under which EMCORE guaranteed the
payment

                                       50

  Table of Contents

when due of the monthly rent, and all other additional rent, interest and charges to be paid by SDI under the Lease Agreement.

Customer Settlement Agreement



On November 17, 2020, we entered into an agreement with a customer to resolve
certain potential product claims (the "Customer Settlement Agreement"). In
exchange for a release of any and all potential claims the customer may have
related to the applicable product, we have agreed to provide up to $1.5 million
of product discounts on future purchases from us by the customer. We recorded
the full potential expense of $1.5 million in the fiscal year ended September
30, 2020 within Research and Development expense.

Critical Accounting Policies

The preparation of consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities, as of the date of the financial statements, and the reported amounts of revenue and expenses during the reported period.



We develop estimates based on historical experience and on various assumptions
about the future that are believed to be reasonable based on the best
information available to us. Our reported financial position or results of
operations may be materially different under changed conditions or when using
different estimates and assumptions, particularly with respect to significant
accounting policies. In the event that estimates or assumptions prove to differ
from actual results, adjustments are made in subsequent periods to reflect more
current information. A listing and description of our critical accounting
policies includes the following:

Inventory


Inventory is stated at the lower of cost or net realizable value (first-in,
first-out). Inventory that is expected to be used within the next 12 months is
classified as current inventory. We write-down inventory once it has been
determined that conditions exist that may not allow the inventory to be sold for
its intended purpose or the inventory is determined to be excess or obsolete
based on assumptions about future demand and market conditions. The charge
related to inventory write-downs is recorded as a cost of revenue. We evaluate
inventory levels at least quarterly against sales forecasts on a significant
part-by-part basis, in addition to determining its overall inventory risk. We
have incurred, and may in the future incur, charges to write-down our inventory.
See   Note 8 - Inventory   in the notes to the consolidated financial statements
for additional information related to our inventory.

Income Taxes



In accordance with the authoritative guidance on accounting for income taxes, we
recognize income taxes using an asset and liability approach. This approach
requires the recognition of taxes payable or refundable for the current year and
deferred tax liabilities and assets for the future tax consequences of events
that have been recognized in our consolidated financial statements or tax
returns. The measurement of current and deferred taxes is based on provisions of
the enacted tax law and the effects of future changes in tax laws or rates are
not anticipated.

The authoritative guidance provides for recognition of deferred tax assets if
the realization of such deferred tax assets is more likely than not to occur
based on an evaluation of all available evidence, both positive and negative,
and the relative weight of the evidence. We have determined that at this time it
is more likely than not that deferred tax assets attributable to all other items
will not be realized, primarily due to uncertainties related to our ability to
utilize our net operating loss carryforwards before they expire. Accordingly, we
have established a valuation allowance for such deferred tax assets which we do
not expect to realize. If there is a change in our ability to realize our
deferred tax assets for which a valuation allowance has been established, then
our tax valuation allowance may decrease in the period in which we determine
that realization is more likely than not. Likewise, if we determine that it is
not more likely than not that deferred tax assets will be realized, then a
valuation allowance may be established for such deferred tax assets and our tax
provision may increase in the period in which we make the determination. See

Note 12 - Income and Other Taxes in the notes to the consolidated financial statements for additional information related to our income taxes.

Revenue Recognition

We recognize revenue in accordance with the Financial Accounting Standards
Board's ("FASB") Accounting Standards Codification ("ASC") 606 Revenue from
Contracts with Customers. The majority of our products have shipping terms that
are free on board or free carrier alongside shipping point, which means that we
fulfill our delivery obligation and control has transferred to the customer when
the goods are handed over to the freight carrier at our shipping dock. In those
instances where inventory is maintained at a consigned location, revenue is
recognized only when our customer pulls product for use and control has
transferred to the customer. Any warranty cost and remaining obligations that
are inconsequential or perfunctory are accrued when the corresponding revenue is
recognized.

                                      ***

The above listing is not intended to be a comprehensive list of all of our
accounting policies. In many cases, U.S. GAAP specifically dictates the
accounting treatment of a particular transaction. There are also areas in which
management's judgment in selecting any available alternative would not produce a
materially different result. For a complete discussion of our accounting
policies, recently adopted accounting pronouncements, and other required U.S.
GAAP disclosures, we refer you to the accompanying notes to our consolidated
financial statements in this Annual Report.

Aerospace and Defense Revenue:



For the fiscal year ended September 30, 2020, our Aerospace and Defense revenue
increased $22.2 million, or 67%, compared to the same period in the prior year.
Included in Aerospace and Defense revenue is $30.3 million and $9.8 million of
revenue from SDI for the fiscal years ended September 30, 2020 and 2019,
respectively, partially offset by a decrease in our other Aerospace and Defense
revenue of $4.7 million. For the fiscal year ended September 30, 2020, our
Navigation and Inertial Sensing product line revenue increased $15.8 million
compared to the same period in the prior year, primarily due to inclusion of SDI
revenue, of $20.5 million, for the full 2020 fiscal year, and an increase in
revenue from our Defense Optoelectronics product line of $6.4 million compared
to the same period in the prior year partially offset by a decrease in our other
Aerospace and Defense revenue of $4.7 million. For the fiscal year ended
September 30, 2020, our Defense Optoelectronics product line revenue increase
was primarily due to an increase in products sold arising from increased
customer demand.

Broadband Revenue:



For the fiscal year ended September 30, 2020, our Broadband revenue increased
$0.7 million, or 1%, compared to the same period in the prior year, primarily
due to higher customer demand in the CATV Lasers and Transmitters and Sensing
product lines partially offset by a decrease in demand of the Chips product

line.

Our cost of revenue consists of raw materials, compensation expense including
non-cash stock-based compensation expense, depreciation expense and other
manufacturing overhead costs, expenses associated with excess and obsolete
inventories, and product warranty costs. Historically, our cost of revenue as
a percentage of revenue, which we refer to as our gross margin, has fluctuated
significantly due to product mix, manufacturing yields and sales volumes, and
inventory and specific product warranty charges.

Consolidated gross margins were 32.3% and 17.3% for the fiscal years ended September 30, 2020 and 2019, respectively.



Stock-based compensation expense within cost of revenue totaled approximately
$0.7 million and $0.5 million for the fiscal years ended September 30, 2020 and
2019, respectively.

Aerospace and Defense Gross Profit:



For the fiscal year ended September 30, 2020, Aerospace and Defense gross profit
increased $7.5 million, or 82%, compared to the same period in the prior year,
primarily due to higher revenue, of which $9.3 million results from the
inclusion of SDI gross profit in the fiscal year ended September 30, 2020,
compared to a $2.6 million inclusion of SDI gross profit in the fiscal year
ended September 30, 2019. For the fiscal years ended September 30, 2020 and
2019, Aerospace and Defense gross margin was 30.3% and 27.8%, respectively. The
higher gross margin in the fiscal year ended September 30, 2020 is primarily due
to improved product mix.

Broadband Gross Profit:

For the fiscal year ended September 30, 2020, Broadband gross profit increased
$13.0 million, or 221%, compared to the same period in the prior year, primarily
as a result of improved product mix in the fiscal year ended September 30, 2020
and product costs and inventory charges related to excess and obsolete inventory
in the fiscal year ended September 30, 2019. For the fiscal years ended
September 30, 2020 and 2019, Broadband gross margin was 34.3% and 10.9%,
respectively. The higher gross margin in the fiscal year ended September 30,
2020 was primarily the result of improved product mix and lower product costs
and inventory related charges.

Selling, General and Administrative ("SG&A")



SG&A consists primarily of compensation expense including non-cash stock-based
compensation expense related to executive, finance, and human resources
personnel, as well as sales and marketing expenses, professional fees, legal and
patent-related costs, and other corporate-related expenses.

Stock-based compensation expense within SG&A totaled approximately $2.1 million and $1.5 million for the fiscal years ended September 30, 2020 and 2019, respectively.



SG&A expense for the fiscal year ended September 30, 2020 was lower than the
amount reported in the same period in the prior year, primarily due to lower
attorneys' fees and costs arising from litigation proceedings, partially offset
by an increase in compensation, insurance and bad debt expenses.

As a percentage of revenue, SG&A expenses were 22.4% and 36.8% for the fiscal years ended September 30, 2020 and 2019, respectively.

Research and Development ("R&D")



R&D consists primarily of compensation expense including non-cash stock-based
compensation expense, as well as engineering and prototype costs, depreciation
expense, and other overhead expenses, as they relate to the design, development,
and testing of our products. Our R&D costs are expensed as incurred. We believe
that in order to remain competitive, we must invest significant financial
resources in developing new product features and enhancements and in maintaining
customer satisfaction worldwide.

Stock-based compensation expense within R&D totaled approximately $0.7 million and $0.6 million for the fiscal years ended September 30, 2020 and 2019, respectively.



For the fiscal years ended September 30, 2020 and 2019, Aerospace and Defense
R&D expense was $17.5 million and $10.4 million, respectively. For the fiscal
years ended September 30, 2020 and 2019, Broadband R&D expense was $2.8 million
and $9.0 million, respectively.

R&D expense for the fiscal year ended September 30, 2020 was higher than the
amounts reported in the same period in the prior year primarily due to the
expense arising from the Customer Settlement Agreement of $1.5 million and an
increase in compensation costs (including due to a higher R&D headcount than the
prior period due to the SDI acquisition), partially offset by lower project
spending, primarily in Aerospace and Defense, and an overall reduction in
Broadband R&D expense.

As a percentage of revenue, R&D expenses were 18.4% and 22.3% for the fiscal years ended September 30, 2020 and 2019, respectively.

Operating Loss



Operating loss represents revenue less the cost of revenue and direct operating
expenses incurred. As a percentage of revenue, our operating loss was (6.4)% and
(41.5)% for the fiscal years ended September 30, 2020 and 2019, respectively.
The decrease in operating loss as a percentage of revenue in the fiscal years
ended September 30, 2020 compared to the same period in the prior year is
primarily due to the increase in gross profit, the gain on sale of equipment of
$2.0 million and the Concord Real Property of $0.3 million, and the decrease in
SG&A expense in the fiscal year ended September 30, 2020.

Other Income

Interest Income, net


During the fiscal years ended September 30, 2020 and 2019, we recorded $0.2
million and $1.0 million, respectively, of interest income earned on cash and
cash equivalents balances, which was partially offset by interest expense and
letter of credit fees related to our Credit Facility (as defined below).
Interest income for the fiscal year ended September 30, 2020 was lower than the
amount reported in the same period in the prior year due to the impact of
COVID-19 on U.S. financial markets and lower cash and cash equivalents balances.

Foreign Exchange



Gains or losses from foreign currency transactions denominated in currencies
other than the U.S. dollar, both realized and unrealized, are recorded as
foreign exchange gain (loss) on our consolidated statements of operations and
comprehensive loss. The gain (losses) recorded relate to the change in value of
the Yuan Renminbi relative to the U.S. dollar.

Income Tax Expense

For each of the fiscal years ended September 30, 2020 and 2019, we recorded income tax expense of approximately $0.1 million. Income tax expense for the fiscal year ended September 30, 2020 is composed primarily of state minimum tax

Aerospace and Defense Revenue:



For the fiscal year ended September 30, 2019, our Aerospace and Defense revenue
increased $19.5 million, or 144%, compared to the same period in the prior year.
Included in Aerospace and Defense revenue is $9.8 million and $0 of revenue from
SDI for the fiscal years ended September 30, 2019 and 2018, respectively. For
the fiscal year ended September 30, 2019, our Navigation and Inertial Sensing
product line revenue increased $16.0 million compared to the same period in the
prior year, primarily due to the increase of SDI revenue of $9.8 million, and an
increase of $3.5 million in our Defense Optoelectronics product line, and an
increase in our other Aerospace and Defense revenue of $6.2 million. For the
fiscal year ended September 30, 2019, our Defense Optoelectronics product line
revenue increase was primarily due to an increase in products sold arising

from
increased customer demand.

Broadband Revenue:

For the fiscal year ended September 30, 2019, our Broadband revenue decreased
$17.9 million, or 25%, compared to the same period in the prior year primarily
due to lower customer demand in the CATV Lasers and Transmitters product lines
partially offset by an increase in our Sensing and Chips product lines.

Our cost of revenue consists of raw materials, compensation expense including
non-cash stock-based compensation expense, depreciation expense and other
manufacturing overhead costs, expenses associated with excess and obsolete
inventories, and product warranty costs. Historically, our cost of revenue as
a percentage of revenue, which we refer to as our gross margin, has fluctuated
significantly due to product mix, manufacturing yields and sales volumes, and
inventory and specific product warranty charges.

Consolidated gross margins were 17.3% and 21.6% for the fiscal years ended September 30, 2019 and 2018, respectively.

Stock-based compensation expense within cost of revenue totaled approximately $0.5 million during each of the fiscal years ended September 30, 2019 and 2018.

Aerospace and Defense Gross Profit:



For the fiscal year ended September 30, 2019, Aerospace and Defense gross profit
increased $6.8 million, or 283%, compared to the same period in the prior year,
primarily due to higher revenue, of which $2.6 million results from the
inclusion of SDI gross profit in the fiscal year ended September 30, 2019,
compared to a $0 inclusion of SDI gross profit in the fiscal year ended
September 30, 2018. For the fiscal years ended September 30, 2019 and 2018,
Aerospace and Defense gross margin was 27.8% and 17.7%, respectively. The higher
gross margin in the fiscal year ended September 30, 2019 was primarily due to
higher revenue and product mix.

Broadband Gross Profit:



For the fiscal year ended September 30, 2019, Broadband gross profit decreased
$10.2 million, or 63%, compared to the same period in the prior year, primarily
as a result of the decrease in revenue and product mix in the fiscal year ended
September 30, 2019, and an increase in product costs and inventory related
charges related to excess and obsolete inventory in the fiscal year ended
September 30, 2019. For the fiscal years ended September 30, 2019 and 2018,
Broadband gross margin was 10.9% and 22.3%, respectively. The lower gross margin
in the fiscal year ended September 30, 2019 was primarily the result of product
mix and higher product costs and inventory related charges.

Selling, General and Administrative ("SG&A")



SG&A consists primarily of compensation expense including non-cash stock-based
compensation expense related to executive, finance, and human resources
personnel, as well as sales and marketing expenses, professional fees, legal and
patent-related costs, and other corporate-related expenses.

Stock-based compensation expense within SG&A totaled approximately $1.5 million and $2.6 million for the fiscal years ended September 30, 2019 and 2018.



SG&A expense for the fiscal year ended September 30, 2019 was higher than the
amount reported in the prior year primarily due to an increase in expense for
professional services of $5.7 million, primarily as a result of the litigation
proceedings with Phoenix, the recording of $3.8 million of attorneys' fees and
costs arising from the arbitrator's modified partial final award in the
litigation proceedings with Phoenix, the inclusion of $1.8 million of expense at
SDI for the period of June 7, 2019 through September 30, 2019 and costs related
to the acquisition of SDI of $0.8 million, partially offset by a decrease in
compensation expenses and an allowance for bad debt expenses.

Research and Development ("R&D")



R&D consists primarily of compensation expense including non-cash stock-based
compensation expense, as well as engineering and prototype costs, depreciation
expense, and other overhead expenses, as they related to the design,
development, and testing of our products. Our R&D costs are expensed as
incurred. We believe that in order to remain competitive, we must invest
significant financial resources in developing new product features and
enhancements and in maintaining customer satisfaction worldwide.

Stock-based compensation expense within R&D totaled approximately $0.6 million for each of the fiscal years ended September 30, 2019 and 2018.



For the fiscal years ended September 30, 2019 and 2018, Aerospace and Defense
R&D expense was $10.4 million and $4.2 million, respectively. For the fiscal
years ended September 30, 2019 and 2018, Broadband R&D expense was $9.0 million
and $11.2 million, respectively.

R&D expense for the fiscal year ended September 30, 2019 was higher than the
amounts reported in the same period in 2018 primarily due to an increase in
compensation costs and project spending, primarily in Navigation and Inertial
Sensing.

As a percentage of revenue, R&D expenses were 22.3% and 18.0% for the fiscal years ended September 30, 2019 and 2018, respectively.

Operating Loss



Operating loss represents revenue less the cost of revenue and direct operating
expenses incurred. Operating loss is a measure that executive management uses to
assess performance and make decisions. As a percentage of revenue, our operating
loss was (41.4)% and (21.5)% for the fiscal years ended September 30, 2019 and
2018, respectively. The increase in operating loss as a percentage of revenue in
the fiscal year ended September 30, 2019 compared to the prior year is primarily
due to a decrease in gross profit and an increase in SG&A and R&D expense in the
fiscal year ended September 30, 2019.

Other Income

Interest Income, net


During the fiscal years ended September 30, 2019 and 2018, we recorded $1.0

Income Tax Benefit (Expense)



For the fiscal year ended September 30, 2019, we recorded income tax expense of
approximately $0.1 million. For the fiscal year ended September 30, 2018, we
recorded income tax benefit of approximately $0.4 million. Income tax expense
for the fiscal year ended September 30, 2019 is primarily comprised of state
minimum tax expense. Income tax benefit for the fiscal year ended September 30,
2018 is primarily comprised of the effect of the Tax Cuts and Jobs Act of 2017
which eliminated Alternative Minimum Taxes and resulted in a refund of amounts
that we paid in prior fiscal years.

Liquidity and Capital Resources



Historically in most periods we have consumed cash from operations and incurred
operating losses from continuing operations. We have managed our liquidity
position through the sale of assets and cost reduction initiatives, as well as,
from time to time in prior periods, borrowings from our Credit Facility (defined
below) and capital markets transactions.

As of September 30, 2020, cash and cash equivalents totaled approximately $30.5
million and net working capital totaled approximately $61.1 million. Net working
capital, calculated as current assets minus current liabilities, is a financial
metric we use which represents available operating liquidity. With respect to
measures related to liquidity:

Credit Facility: On November 11, 2010, we entered into a Credit and Security

Agreement (as amended to date, the "Credit Facility") with Wells Fargo Bank,

? N.A. ("Wells Fargo"). The Credit Facility is secured by the Company's assets

and is subject to a borrowing base formula based on the Company's eligible

accounts receivable, inventory, and machinery and equipment accounts.


The Credit Facility matures in November 2021 and currently provides us with a
revolving credit line of up to $15.0 million, subject to a borrowing base
formula, that can be used for working capital requirements, letters of credit,
acquisitions, and other general corporate purposes subject to a requirement, for
certain specific uses, that the Company have liquidity of at least $25.0 million
after such use. The Credit Facility requires us to maintain (a) liquidity of at
least $10.0 million and (b) excess availability of at least $1.0 million. See
  Note 11 - Credit Facilities   and Debt in the notes to the consolidated
financial statements for additional disclosures. As of November 30, 2020, there
was no outstanding balance under this Credit Facility, approximately $0.5
million reserved for one outstanding stand-by letter of credit and approximately
$9.7 million available for borrowing.

PPP Loan: On May 3, 2020, we entered into a Paycheck Protection Program

Promissory Note and Agreement (the "PPP Loan Agreement") with Wells Fargo under

the Paycheck Protection Program ("PPP") established under the Coronavirus Aid,

Relief and Economic Security Act ("CARES Act") to receive loan proceeds of

approximately $6.5 million (the "PPP Loan"), which we received on May 6, 2020.

The PPP Loan matures on May 3, 2022 and bears interest at a fixed rate of 1.00%

per annum, payable monthly. Monthly payments in the amount of $273,160 will be

due and payable beginning at such time as is in accordance with the terms of

the Paycheck Protection Flexibility Act of 2020 and continuing each month

? thereafter until maturity of the PPP Loan. There is no prepayment penalty.

Under the terms of the PPP, all or a portion of the principal may be forgiven

if the PPP Loan proceeds are used for qualifying expenses as described in the

CARES Act, such as payroll costs, benefits, rent, and utilities. No assurance

is provided that we will obtain forgiveness of the PPP Loan in whole or in

part. With respect to any portion of the PPP Loan that is not forgiven, the PPP

Loan will be subject to customary provisions for a loan of this type, including

customary events of default relating to, among other things, payment defaults

and breaches of the provisions of the PPP Loan Agreement. As of September 30,

2020, approximately $6.5 million was outstanding related to the PPP Loan.




We have a history of operating losses and negative cash flows from operations.
We believe that our existing balances of cash and cash equivalents, cash flows
from operations, amounts expected to be available under our Credit Facility and
any amounts that may be available to us under governmental lending programs will
provide us with sufficient financial resources to meet our cash requirements for
operations, working capital, and capital expenditures for at least the next
twelve months from the issuance date of these financial statements. We have
taken a number of actions to continue to support our operations and meet our
obligations, including completing the sale of the Concord Real Property,
headcount

reductions and other cost reductions. In addition, should we require more
capital than what is generated by our operations, we could engage in additional
sales or other monetization of certain fixed assets and real estate, additional
cost reductions, or elect to raise capital in the U.S. through debt or equity
issuances. These alternatives may not be available to us on reasonable terms or
at all, could result in higher effective tax rates, increased interest expense,
and/or dilution of our earnings.

Fiscal 2020:

For the fiscal year ended September 30, 2020, our operating activities used cash
of $3.9 million, primarily due to our net loss of $7.0 million, changes in our
operating assets and liabilities (or working capital components, which includes
non-current inventory) of $3.8 million and gain on disposal of assets of $2.3
million, partially offset by adjustments for non-cash charges, including
depreciation and amortization expense of $5.5 million, stock-based compensation
expense of $3.5 million, issuance of restricted stock units of $0.4 million,
product warranty provision of $0.4 million and bad debt provision of $0.2
million. The change in our operating assets and liabilities was primarily the
result of an increase in accounts receivable and contract assets of $7.5
million, inventory of $1.2 million and other assets of $13.5 million, partially
offset by an increase in accounts payable of $6.1 million and accrued expenses
and other liabilities of $12.2 million.

Fiscal 2019:

of $15.2 million, primarily due to our net loss of $36.0 million, partially
offset by a gain on disposal of equipment of $0.3 million, changes in our
operating assets and liabilities (or working capital components, which includes
non-current inventory) of $10.7 million, depreciation and amortization expense
of $7.1 million, stock-based compensation expense of $2.6 million, warranty
provision of $0.2 million and bad debt provision of $0.1 million. The change in
our operating assets and liabilities was primarily the result of a decrease in
accounts receivable of $4.0 million and an increase in accrued expenses and
other liabilities of $5.0 million, partially offset by a decrease in inventory
of $6.5 million and other assets of $0.2 million and a decrease in accounts
payable of $4.5 million.

Fiscal 2018:



For the fiscal year ended September 30, 2018, our operating activities provided
cash of $1.5 million primarily due to changes in our operating assets and
liabilities (or working capital components, which includes non-current
inventory) of $8.2 million, depreciation and amortization expense of $5.6
million, stock-based compensation expense of $3.6 million, provision for
doubtful accounts of $0.6 million, warranty provision of $0.4 million and loss
on disposal of equipment of $34,000 partially offset by our net loss of $17.5
million. The change in our operating assets and liabilities was primarily the
result of a decrease in accounts receivable of $2.4 million, inventory of $5.1
million, other assets of $0.6 million and an increase in accounts payable of
$0.5 million partially offset by a decrease in accrued expenses and other
liabilities of $0.4 million.

Working Capital Components:



Accounts Receivable: We generally expect the level of accounts receivable at any
given quarter end to reflect the level of sales in that quarter. Our accounts
receivable balances have fluctuated historically due to the timing of account
collections, timing of product shipments, and/or change in customer credit
terms.

Inventory: We generally expect the level of inventory at any given quarter end
to reflect the change in our expectations of forecasted sales during the
quarter. Our inventory balances have fluctuated historically due to the timing
of customer orders and product shipments, changes in our internal forecasts
related to customer demand, as well as adjustments related to excess and
obsolete inventory and the purchase of non-current inventory.

Accounts Payable: The fluctuation of our accounts payable balances is primarily driven by changes in inventory purchases as well as changes related to the timing of actual payments to vendors.



Accrued Expenses: Our largest accrued expense typically relates to compensation.
Historically, fluctuations of our accrued expense accounts have primarily
related to changes in the timing of actual compensation payments, receipt or
application of advanced payments, adjustments to our warranty accrual, and
accruals related to professional fees.

Contractual Obligations and Commitments



Our contractual obligations and commitments for fiscal 2021 and over the next
five fiscal years are summarized in the table below (and are presented as of
September 30, 2020):


(in thousands)

                                           Total       Less than a year     1 to 3 years     4 to 5 years      Over 5 years

Purchase obligations                      $ 15,315    $           14,199    $       1,056    $          60    $            -

Interest payments are not included in the contractual obligations and commitments table above since they are insignificant to our consolidated results of operations.

The contractual obligations and commitments table above also excludes unrecognized tax benefits, because we are unable to reasonably estimate the period during which this obligation may be incurred, if at all. As of September 30, 2020, we had unrecognized tax benefits of $0.4 million.

Purchase Obligations


Our purchase obligations represent an estimate of all open purchase orders and
contractual obligations in the ordinary course of business for which we have not
received the goods or services as of September 30, 2020. Although open purchase
orders are considered enforceable and legally binding, the terms generally allow
us the option to cancel, reschedule and adjust our requirements based on our
business needs prior to the delivery of goods or performance of services.

The purchase obligations of $15.3 million set forth above include, as of
September 30, 2020, $1.0 million that we have committed for the purchase and
installation of capital equipment. In addition, we expect to incur, during the
fiscal year ending September 30, 2021, an additional $1.2 million to complete
the purchase and installation of capital equipment, which we expect to fund

via
cash on hand.

Asset Retirement Obligations



We have known conditional ARO conditions, such as certain asset decommissioning
and restoration of rented facilities to be performed in the future. Our ARO
includes assumptions related to renewal option periods where we expect to extend
facility lease terms. Revisions in estimated liabilities can result from
revisions of estimated inflation rates, escalating retirement costs, and changes
in the estimated timing of settling the ARO. See   Note 13 - Commitments and
Contingencies   in the notes to the consolidated financial statements for
additional information related to our AROs.

Operating Leases

Operating leases include non-cancelable terms and exclude renewal option periods, property taxes, insurance and maintenance expenses on leased properties. See Note 13 - Commitments and Contingencies in the notes to the consolidated financial statements for additional information related to our operating lease obligations.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements other than our operating leases described above that have or are reasonably likely to have a current or future material effect on our consolidated financial condition, results of operations, liquidity, capital expenditures or capital resources.
