Overview



We are North America's leading provider of the cleanest fuel for the
transportation market, based on the number of stations operated and the amount
of gasoline gallon equivalents ("GGEs") of renewable natural gas ("RNG"),
compressed natural gas ("CNG") and liquefied natural gas ("LNG") delivered.
Through our sales of Redeem™ RNG, which is derived from biogenic methane
produced by the breakdown of organic waste, we help thousands of vehicles, from
airport shuttles to city buses to waste and heavy-duty trucks, to reduce their
amount of climate-harming greenhouse gas by at least 70% and up to 300%
depending on the source of the RNG feedstock while also reducing criteria
pollutants such as Oxides of Nitrogen (NOx). Redeem RNG is delivered as CNG and
LNG.

Our principal business is supplying RNG, CNG and LNG for medium and heavy-duty
vehicles and providing operation and maintenance ("O&M") services for public and
private vehicle fleet customer stations. As a comprehensive solution provider,
we also design, build, operate and maintain fueling stations; sell and service
natural gas fueling compressors and other equipment used in CNG stations and LNG
stations; offer assessment, design and modification solutions to provide
operators with code-compliant service and maintenance facilities for natural gas
vehicle fleets; transport and sell CNG and LNG via "virtual" natural gas
pipelines and interconnects; procure and sell RNG; sell tradable credits we
generate by selling RNG and conventional natural gas as a vehicle fuel,
including Renewable Identification Numbers ("RIN Credits" or "RINs") under the
federal Renewable Fuel Standard Phase 2 and credits under the California and the
Oregon Low Carbon Fuel Standards (collectively "LCFS Credits"); help our
customers acquire and finance natural gas vehicles; and obtain federal, state
and local credits, grants and incentives. In addition, before March 31, 2017, we
produced RNG at our own production facilities (which we sold, along with certain
of our other RNG production assets to BP Products North America ("BP"), in a
transaction we refer to as the "BP Transaction"), and before December 29, 2017,
we manufactured natural gas fueling compressors and other equipment used in CNG
stations (which we combined with Landi Renzo S.p.A.'s natural gas fueling
compressor manufacturing business in a newly formed company, SAFE&CEC S.r.l., in
a transaction we refer to as the "CEC Combination").

We serve fleet vehicle operators in a variety of markets, including heavy-duty
trucking, airports, refuse, public transit, and government fleets. We believe
these fleet markets will continue to present a growth opportunity for natural
gas vehicle fuel for the foreseeable future. As of June 30, 2020, we served over
1,000 fleet customers operating over 48,000 natural gas vehicles, and we
currently own, operate or supply approximately 550 natural gas fueling stations
in 41 states in the United States and five provinces in Canada. We also provide
fuel and services to industrial and institutional energy users.

Impact of COVID-19

The COVID-19 pandemic has resulted, and is likely to continue to result, in significant economic disruption and has adversely affected and will likely continue to adversely affect our business. Our operations have been designated "essential critical infrastructure work" in the energy sector by the U.S. Department of Homeland Security, meaning that we have been able to continue operating to the fullest extent possible. While continuing our business operations, we are focused on protecting the health and wellbeing of our employees, customers and the communities in which we operate.

Beginning on March 16, 2020, the vast majority of our employees transitioned to
remote working arrangements. Importantly, this did not result in any adverse
effects to our operations, including financial reporting systems, internal
control over financial reporting and disclosure controls and procedures.
Additionally, our technicians and O&M services continued to operate effectively,
and we believe our supply chain has not been disrupted. All of our natural gas
fueling stations have remained fully operational during the COVID-19 pandemic
and continue to provide access to customers--many that are supplying essential
services. Further, we have not experienced any challenges implementing business
continuity plans and have not incurred, and do not expect to incur, material
expenditures related to the same.

Beginning on April 27, 2020 we commenced a phased return of employees to their
respective offices and have adopted and applied protocols and procedures in
accordance with federal, state and local government policies and mandates and
Centers for Disease Control (CDC) guidelines. Specifically, we have implemented
enhanced cleaning and disinfecting protocols and temperature and COVID-19
screening questionnaires for the health and safety of our employees, customers
and the communities in which we operate. We have provided personal protective
equipment (including masks and gloves) and hand sanitizer, we have modified
office seating, we expect all our employees to maintain appropriate physical
distancing, and we continue to restrict employee travel in accordance with the
various state health orders.

We began to see the negative effects of COVID-19 on volumes delivered in
mid-March and continued to see declines in volumes delivered for the three
months ended June 30, 2020, as compared to the three months ended June 30, 2019.
Volumes delivered for June 2020 increased 5% over May 2020 but remained 13%
lower compared to June 2019. The most significant negative effects of COVID-19
in relation to our volumes continue to be seen in the airports (fleet services),
public transit and government fleet customer markets, which were down from the
three months ended June 30, 2019 by between 25% and 45% due to federal, state
and local government mandates to restrict normal daily activities, as well as
travel bans, quarantines and "shelter-in-place" orders, with single digit growth
in trucking and refuse markets in the three months ended June 30, 2020 from the
three months ended June 30, 2019, where we saw more essential businesses
operating. Although some of these restrictions have been lifted or scaled back
in recent months, a recent surge of COVID-19 has resulted in the re-imposition
of certain restrictions and may lead to other restrictions being re-implemented
in response to efforts to reduce the spread of COVID-19. These measures, which
may remain in place for a significant amount of time, may further adversely
affect airports, public transit and government fleet customer markets.

Our volume of GGEs delivered in the second quarter of 2020 declined 10% compared
to the prior year period with the lowest volumes delivered being experienced in
May 2020. Although there was an increase in volume in June 2020 compared to May
2020, we believe the year over year declines in volumes will continue beyond
June and gradually recover at a slower pace than previously anticipated due to
the more recent resurgence and prolonging effect of the COVID-19 pandemic.
Declines in volume have resulted and are expected to continue to result in lower
gross margin dollars and likely a lower gross margin per GGE due to lower output
on fixed operating costs and the effect of less RIN and LCFS revenue. Lower
volumes have affected and may continue to affect our AFTC revenue as a portion
of the decline in volume is from AFTC eligible volumes. During the second
quarter of 2020, we also experienced lower than anticipated operating expenses
due to lower spending as a result of reduced business activities. We expect this
trend of lower spending to continue at least until our business activities begin
to normalize to levels prior to the COVID-19 pandemic, which will help mitigate
the reduction in gross profit margins associated with prolonged year over year
declines in our overall volume. We also recorded a $2.5 million station asset
disposal gain during the second quarter which helps mitigate the negative effect
of COVID-19 on our 2020 financial results. We believe the lower gross profit
margins from lower volumes can be sufficiently mitigated by our continued lower
operating expenses together with the station asset disposal gain assuming there
is not a further deterioration or lack of any recovery from the COVID-19
pandemic during the remainder of 2020. As such, we continue to estimate a
negative effect of $11 million to our net operating results for 2020 as a result
of COVID-19. Given the dynamic nature of these circumstances, significant
uncertainty exists concerning the duration of business disruption and the full
extent of the effect of COVID-19 on our business, results of operations and
financial condition. Additionally, the effects of COVID-19, low oil prices and
the adoption of government policies and programs, or increased popular
sentiment, in favor of other vehicle technologies or fuels may delay adoption of
natural gas vehicles by new customers and expansion by existing customers,
particularly heavy-duty natural gas trucks, which would adversely affect our
previously anticipated volume growth. For more information, see "Risk Factors"
in Part II, Item 1A of this report.

We believe we have sufficient liquidity to support business operations through
this volatile period, including total cash and cash equivalents and short-term
investments of $95.7 million as of June 30, 2020. During the three months ended

                                       28

June 30, 2020, we collected our AFTC receivables related to 2018 and 2019 AFTC
volumes which provided us with approximately $47 million, net in additional cash
to support our operations, and helped repay the remaining $50.0 million in
principal amount of our 7.5% Notes. We will also collect the 2020 AFTC revenue
throughout 2020, which we expect to be between $16 million and $20 million
giving consideration to the effect of COVID-19 described above. As of June 30,
2020, we had approximately $6.8 million of current debt. Additionally, we are
continuously evaluating and taking actions to reduce costs and spending across
our organization. This includes limiting travel, reducing hiring activities and
limiting discretionary spending. We also reduced our anticipated capital
expenditures for 2020 in light of COVID-19 to $14.0 million for our core
business and $2.0 million for NG Advantage. Additionally, we could suspend, or
limit repurchases under, our share repurchase program which was authorized for
up to $30.0 million, of which $10.5 million, excluding fees and commissions, had
been spent through June 30, 2020 and $12.7 million had been spent through July
31, 2020.

regarding the commodity swap and customer contracts.

Recent Developments



Chevron Adopt-a-Port. In June 2020, we entered into an agreement with Chevron to
provide truck operators serving the ports of Los Angeles and Long Beach with
cleaner, carbon-negative RNG to reduce emissions. Under the agreement, Chevron
will provide funding to allow truck operators to subsidize the cost of buying
new RNG-powered trucks and will supply RNG to our stations near the ports.

Share Repurchase Program. On March 12, 2020, our Board of Directors approved a
share repurchase program of up to $30.0 million (exclusive of fees and
commissions) of our outstanding common stock (the "Repurchase Program"). The
Repurchase Program does not have an expiration date, does not obligate us to
acquire any specific number of shares, and may be suspended or discontinued at
any time. As of June 30, 2020, we had utilized $10.5 million under the
Repurchase Program to purchase 6,112,499 shares of our common stock for a total
cost of $10.7 million. As of July 31, 2020, we had utilized $12.7 million under
the Repurchase Program to purchase 7,005,849 shares of our common stock.

7.5% Notes. In May 2020, we repaid the remaining $50.0 million of outstanding 7.5% Notes plus related accrued and unpaid interest thereon.



NG Advantage. In February 2020, we converted the principal and accrued interest
under the November 2019 Convertible Note (as defined in Note 3) into common
units of NG Advantage, LLC ("NG Advantage") and received common units pursuant
to the guaranty agreement entered in February 2018, resulting in an increase in
our controlling interest in NG Advantage to 93.3%.

Business Risks and Uncertainties and Other Trends


Our business and prospects are exposed to numerous risks and uncertainties. For
more information, see "Risk Factors" in Part II, Item 1A of this report. In
addition, our performance in any period may be affected by various trends in our
business and our industry, including certain seasonality trends. See the
description of the key trends in our past performance and anticipated future
trends included in the MD&A contained in our 2019 Form 10-K. Except as set forth
below, and in "Impact of COVID-19" above, there have been no material changes to
such trends as described in the MD&A contained in our 2019 Form 10-K.

The market for natural gas as a vehicle fuel is a relatively new and developing
market, and has experienced slow, volatile or unpredictable growth in many
sectors. For example, to date, adoption and deployment of natural gas vehicles,
both in general and in certain of our key customer markets, including heavy-duty
trucking, have been slower and more limited than we anticipated. Also, other
important markets, including airports, refuse and public transit, had slower
volume and customer growth in 2019 and in the six months ended June 30, 2020
that we expect to continue, especially due to the COVID-19 pandemic and the
efforts taken to reduce its spread. Moreover, adoption of and demand for the
different types of natural gas vehicle fuel, including RNG, CNG and LNG, are
subject to significant risks, including decreased LNG volumes in some markets in
recent periods that may continue and may not be sufficiently offset by any
increase in demand for RNG or CNG.

Market prices for RINs and LCFS Credits can be volatile and unpredictable, and
the prices for such credits can be subject to significant fluctuations. The
value of RINs and LCFS Credits (derived from market prices) can materially
affect our revenue. For example, since approximately the beginning of June 2019
to January 2020, market prices for RINs trended to historical lows. Although RIN
prices have generally increased since late January 2020, prices have fluctuated
significantly during 2020 and will likely continue to be volatile.

The market price of our common stock can be volatile and unpredictable. During
the second quarter of 2020, our stock price fluctuated up and down. If a decline
of our market capitalization were sustained we may need to perform

                                       31

goodwill impairment tests more frequently and it is possible that our goodwill could become impaired which could result in a material non-cash charge and adversely affect our results of operations.

Debt Compliance



Certain of the agreements governing our outstanding debt, which are discussed in
Note 12, have certain non-financial covenants with which we must comply. As of
June 30, 2020, we were in compliance with all of these covenants.

Risk Management Activities



Our risk management activities are discussed in the MD&A contained in our 2019
Form 10-K. During the six months ended June 30, 2020, there were no material
changes to these activities.

Critical Accounting Policies and Estimates



The preparation of our condensed consolidated financial statements in conformity
with accounting principles generally accepted in the Unites States of America
requires the appropriate application of accounting policies, some of which
require us to make estimates and assumptions that affect the amounts reported
and related disclosures in our condensed consolidated financial statements. We
base our estimates on historical experience and various assumptions that we
believe are reasonable under the circumstances. To the extent there are
differences between these estimates and actual results, our financial condition
or results of operations could be materially affected.

Our critical accounting policies and the related judgments and estimates are
discussed in the MD&A contained in our 2019 Form 10-K, except for certain
updates regarding our goodwill impairment assessment, which is described below,
and our adoption of new guidance for credit losses effective January 1, 2020,
which is described in Note 1. There have been no other material changes to our
critical accounting policies as described in the MD&A contained in our 2019
Form 10-K.

Impairment of Goodwill

Goodwill represents the excess of costs incurred over the fair value of the net
assets of acquired businesses. We assess our goodwill using either a qualitative
or quantitative approach to determine whether it is more likely than not that
the fair value of our reporting unit is less than its carrying value. We are
required to use judgment when applying the goodwill impairment test, including,
among other considerations, the identification of reporting unit(s), the
assessment of qualitative factors, and the estimation of fair value of a
reporting unit in the quantitative approach. We determined that we are a single
reporting unit for the purpose of goodwill impairment tests. We perform the
impairment test annually on October 1, or more frequently if facts or
circumstances change that would indicate that the carrying amount may be
impaired.

The qualitative goodwill assessment includes the potential effect on a reporting
unit's fair value of certain events and circumstances, including its enterprise
value, macroeconomic conditions, industry and market considerations, cost
factors, and other relevant entity-specific events. If it is determined, based
upon the qualitative assessment, that it is more likely than not that the
reporting unit's fair value is less than its carrying amount, then a
quantitative impairment test is performed. Alternatively, we may bypass the
qualitative assessment for a reporting unit and directly perform the
quantitative assessment.

The quantitative assessment estimates the reporting unit's fair value based on
its market capitalization plus an assumed control premium as evidence of fair
value. The estimates used to determine the fair value of the reporting unit may
change based on results of operations, macroeconomic conditions, stock price
fluctuations or other factors. Changes in these estimates could materially
affect our assessment of the fair value and goodwill impairment for the
reporting unit.

For our most recent goodwill impairment test, which was our annual test
performed on October 1, 2019, we performed a quantitative impairment assessment
for the reporting unit as described above. In this test, the fair value of the
reporting unit exceeded its carrying value by 9%.

                                       32

Table of Contents


We evaluated the recent change in the market price of our common stock and
considered whether there were any other events or circumstances that would more
likely than not reduce the fair value of our reporting unit below its carrying
value on a sustained basis, and concluded it was not more likely than not that
the fair value of our reporting unit decreased below its carrying value, on a
sustained basis. As a result, an interim impairment test was not considered
necessary during the three and six months ended June 30, 2020.

If there were a decline in the market price of our common stock and our market
capitalization, or if other events or circumstances change that would more
likely than not reduce the fair value of our reporting unit below its carrying
value, on a sustained basis, then we may perform impairment tests more
frequently and it is possible that our goodwill could become impaired, which
could result in a material non-cash charge and adversely affect our results of
operations.

Revenue. Revenue decreased by $12.4 million to $59.9 million in the three months
ended June 30, 2020, from $72.3 million in the three months ended June 30, 2019.
This decrease was primarily due to a decrease in volume-related

                                       33

Table of Contents



revenue, a net decrease in fair value of our commodity swap and customer
contracts entered into in connection with our Zero Now truck financing program,
and decreased construction sales, partially offset by AFTC revenue that did not
exist in the second quarter of 2019.

Volume-related revenue, excluding the effect of the change in fair value of our
commodity swap and customer contracts entered in connection with our Zero Now
truck financing program, decreased by $14.1 million between periods,
attributable to a decrease in gallons delivered, and a lower effective price per
gallon delivered. The effect to volume-related revenue as a result of the change
in fair value of our commodity swap and customer contracts entered into in
connection with our Zero Now truck financing program was $(2.0) million, as we
recognized an unrealized gain of $0.6 million in 2019 compared to an unrealized
loss of $(1.5) million in 2020 (see Note 6 for more information).

Our effective price per gallon charged decreased by $0.08 per gallon to $0.58
per gallon in the three months ended June 30, 2020 compared to $0.66 per gallon
in the three months ended June 30, 2019, excluding the effect of the change in
fair value of derivative instruments discussed above. Our effective price per
gallon is defined as revenue generated from selling RNG, CNG, LNG and any
related RINs and LCFS Credits and providing O&M services to our vehicle fleet
customers at stations we do not own and for which we receive a per-gallon or
fixed fee, all divided by the total GGEs delivered less GGEs delivered by
non-consolidated entities, such as entities that are accounted for under the
equity method. The decrease in our effective price per gallon was due to
decreases in natural gas prices and the fuel price mix, which is based on the
variation of fuel types and locations where we deliver fuel.

Station construction sales decreased by $0.7 million between periods due to decreased construction activities.



AFTC revenue increased by $4.4 million between periods due to the absence of
AFTC in the three months ended June 30, 2019. We recognized AFTC revenue for the
vehicle fuel we sold in 2018 and 2019 in the three months ended December 31,
2019.

Cost of sales. Cost of sales decreased by $9.1 million to $38.6 million in the
three months ended June 30, 2020, from $47.6 million in the three months ended
June 30, 2019. This decrease was primarily due to a decrease in gallons
delivered, a decrease in natural gas commodity costs due to the decrease in
natural gas prices, and a $1.7 million decrease in the cost of station
construction activities.

Our effective cost per gallon decreased by $0.04 per gallon to $0.38 per gallon
in the three months ended June 30, 2020 from $0.42 per gallon in the
three months ended June 30, 2019. Our effective cost per gallon is defined as
the total costs associated with delivering natural gas, including gas commodity
costs, transportation fees, liquefaction charges, and other site operating
costs, plus the total cost of providing O&M services at stations that we do not
own and for which we receive a per-gallon or fixed fee, including direct
technician labor, indirect supervisor and management labor, repair parts and
other direct maintenance costs, all divided by the total GGEs delivered less
GGEs delivered by non-consolidated entities, such as entities that are accounted
for under the equity method. The decrease in our effective cost per gallon was
due to decreases in natural gas prices and transportation costs.

Change in fair value of derivative warrants. Change in fair value of derivative
warrants, all of which were issued by our subsidiary, NG Advantage, changed by
$0.4 million to a gain of $0.4 million in the three months ended June 30, 2020,
from a gain of $0.0 million in the three months ended June 30, 2019, due to a
change in the estimated fair value. The warrants expired on July 2, 2020.

Selling, general and administrative. Selling, general and administrative
expenses decreased by $1.0 million to $16.9 million in the three months ended
June 30, 2020, from $17.9 million in the three months ended June 30, 2019. This
decrease was primarily driven by reduced activities and cost reductions due to
the effect of COVID-19, including lower advertising and travel expenses.

Depreciation and amortization. Depreciation and amortization decreased by $0.6
million to $12.1 million in the three months ended June 30, 2020, from $12.6
million in the three months ended June 30, 2019, primarily due to a lower amount
of depreciable assets.

  Table of Contents

Interest expense. Interest expense in the three months ended June 30, 2020 was consistent with the three months ended June 30, 2019.



Other income, net. Other income, net increased $2.2 million from $0.1 million in
the three months ended June 30, 2019 to $2.3 million in the three months ended
June 30, 2020, primarily due to a gain recorded for the disposal of certain
assets.

Loss from equity method investments. Loss from equity method investments increased $0.5 million, primarily due to the operating results of SAFE&CEC S.r.l. being negatively affected by the COVID-19 pandemic.


Income tax expense. Income tax expense increased in the three months ended June
30, 2020 from the three months ended June 30, 2019, primarily due to an increase
in deferred taxes associated with goodwill which were partially offset by a
reduction in the Company's expected state tax expense.

Loss attributable to noncontrolling interest. During the three months ended June
30, 2019 and 2020, we recorded a $1.7 million and $0.3 million loss,
respectively, for the noncontrolling interest in the net loss of NG Advantage.
The noncontrolling interest in NG Advantage represents a 35.4% and 6.7% minority
interest that was held by third parties during the 2019 and 2020 periods,
respectively.

Revenue. Revenue decreased by $4.1 million to $145.9 million in the six months
ended June 30, 2020, from $150.0 million in the six months ended June 30, 2019.
This decrease was primarily due to a decrease in volume-related revenue,
partially offset by a favorable change in fair value of our commodity swap and
customer contracts entered into in connection with our Zero Now truck financing
program, increased station construction sales and AFTC revenue that did not
exist in the prior year period.

Table of Contents


Volume-related revenue, excluding the impact of the change in fair value of our
commodity swap and customer contracts entered in connection with our Zero Now
truck financing program, decreased by $24.2 million between periods,
attributable to a decrease in gallons delivered, and a lower effective price per
gallon delivered. The impact to volume-related revenue as a result of the change
in fair value of our commodity swap and customer contracts entered into in
connection with our Zero Now truck financing program was $8.6 million, as we
recognized an unrealized loss of $(4.4) million in 2019 compared to an
unrealized gain of $4.2 million in 2020 (see Note 6 for more information).

Our effective price per gallon charged decreased by $0.11 per gallon to $0.64
per gallon in the six months ended June 30, 2020 compared to $0.75 per gallon in
the six months ended June 30, 2019, excluding the effect of the change in fair
value of derivative instruments discussed above. Our effective price per gallon
is defined as revenue generated from selling RNG, CNG, LNG and any related RINs
and LCFS Credits and providing O&M services to our vehicle fleet customers at
stations we do not own and for which we receive a per-gallon or fixed fee, all
divided by the total GGEs delivered less GGEs delivered by non-consolidated
entities, such as entities that are accounted for under the equity method. The
decrease in our effective price per gallon was due to decreases in natural gas
prices and the fuel price mix, which is based on the variation of fuel types and
locations where we deliver fuel.

Station construction sales increased by $1.7 million between periods due to increased construction activities.



AFTC revenue increased by $9.8 million between periods due to the absence of
AFTC in the six months ended June 30, 2019. We recognized AFTC revenue for the
vehicle fuel we sold in 2018 and 2019 in the three months ended December 31,
2019.

Cost of sales. Cost of sales decreased by $15.0 million to $91.5 million in the
six months ended June 30, 2020, from $106.4 million in the six months ended June
30, 2019. This decrease was primarily due to a decrease in gallons delivered, a
decrease in natural gas commodity costs due to the decrease in natural gas
prices, and a $0.4 million decrease in the cost of station construction
activities.

Our effective cost per gallon decreased by $0.06 per gallon to $0.43 per gallon
in the six months ended June 30, 2020 from $0.49 per gallon in the six months
ended June 30, 2019. Our effective cost per gallon is defined as the total costs
associated with delivering natural gas, including gas commodity costs,
transportation fees, liquefaction charges, and other site operating costs, plus
the total cost of providing O&M services at stations that we do not own and for
which we receive a per-gallon or fixed fee, including direct technician labor,
indirect supervisor and management labor, repair parts and other direct
maintenance costs, all divided by the total GGEs delivered less GGEs delivered
by non-consolidated entities, such as entities that are accounted for under the
equity method. The decrease in our effective cost per gallon was due to
decreases in natural gas prices and transportation costs.

Change in fair value of derivative warrants. Change in fair value of derivative
warrants, all of which were issued by our subsidiary, NG Advantage, changed by
$1.6 million to a gain of $0.0 million in the six months ended June 30, 2020,
from an expense of $1.6 million in the six months ended June 30, 2019, due to a
change in the estimated fair value. The warrants expired on July 2, 2020.

Selling, general and administrative. Selling, general and administrative
expenses decreased by $1.2 million to $35.2 million in the six months ended June
30, 2020, from $36.4 million in the six months ended June 30, 2019. This
decrease was primarily driven by reduced activities and cost reductions due to
the effect of COVID-19, including lower advertising and travel expenses.

Depreciation and amortization. Depreciation and amortization decreased by $1.1
million to $24.0 million in the six months ended June 30, 2020, from $25.1
million in the six months ended June 30, 2019, primarily due to a lower amount
of depreciable assets.

Interest expense. Interest expense increased by $0.3 million to $4.1 million in
the six months ended June 30, 2020, from $3.7 million in the six months ended
June 30, 2019. This increase was primarily due to an increase in outstanding
indebtedness on the SG Facility between periods.

Other income, net. Other income, net decreased $0.3 million from $2.8 million in
the six months ended June 30, 2019 to $2.5 million in the six months ended June
30, 2020. This decrease was primarily due to lower gains recorded from the
disposal of certain assets.

Loss from equity method investments. Loss from equity method investments decreased $0.1 million between periods, due to improved operating results from MCEP.



Income tax expense. Income tax expense increased in the six months ended June
30, 2020 from the six months ended June 30, 2019, primarily due to an increase
in deferred taxes associated with goodwill which were partially offset by a
reduction in the Company's expected state tax expense.

Loss attributable to noncontrolling interest. During the six months ended June
30, 2019 and 2020, we recorded a $3.6 million and $1.1 million loss,
respectively, for the noncontrolling interest in the net loss of NG Advantage.
The noncontrolling interest in NG Advantage represents a 35.4% and 6.7% minority
interest that was held by third parties during the 2019 and 2020 periods,
respectively.

Liquidity and Capital Resources

Liquidity



Liquidity is the ability to meet present and future financial obligations
through operating cash flows, the sale or maturity of investments or the
acquisition of additional funds through capital management. Our financial
position and liquidity are, and will continue to be, influenced by a variety of
factors, including the level of our outstanding indebtedness and the principal
and interest we are obligated to pay on our indebtedness, which could be
influenced by the potential discontinuance of LIBOR for certain of our debt
instruments that tie interest rates to this metric; the amount and timing of any
additional debt or equity financing we may pursue; our capital expenditure
requirements; any merger, divestiture or acquisition activity; and our ability
to generate cash flows from our operations. We expect cash provided by our
operating activities to fluctuate as a result of a number of factors, including
our operating results and the factors that affect these results, including the
amount and timing of our natural gas vehicle fuel sales, station construction
sales, sales of RINs and LCFS Credits and recognition of government credits, the
effects of COVID-19, grants and incentives, if any; fluctuations in commodity,
station construction and labor costs and natural gas, RIN and LCFS Credit
prices; variations in the fair value of certain of our derivative instruments
that are recorded in revenue; and the amount and timing of our billing,
collections and liability payments.

Cash Flows



Cash provided by operating activities was $49.8 million in the six months ended
June 30, 2020, compared to $8.8 million in the comparable 2019 period. The
increase in cash provided by operating activities was primarily attributable to
collection of 2018 and 2019 AFTC receivables, changes in working capital
resulting from the timing of receipts and payments of cash, and the decrease in
net loss in the six months ended June 30, 2020 from the comparable 2019 period,
partially offset by $7.8 million used to terminate a contract between NG
Advantage and BP.

Cash provided by investing activities was $43.6 million in the six months ended
June 30, 2020, compared to $3.0 million provided by investing activities in the
comparable 2019 period. The increase in cash provided by investing activities
was primarily attributable to an increase in maturities and sales of short-term
investments from the comparable period in 2019, partially offset by a decrease
in proceeds from property and equipment disposals.

Cash used in financing activities was $63.2 million in the six months ended June
30, 2020, compared to $0.0 million provided by financing activities in the
comparable 2019 period. The increase in cash used in financing activities was
primarily attributable to an increase in repayment of debt instruments and
finance lease obligations due to repayment of the 7.5% Notes and repurchases of
common stock during the six months ended June 30, 2020, partially offset by a
decrease in proceeds from debt instruments.

Capital Expenditures, Indebtedness and Other Uses of Cash



We require cash to fund our capital expenditures, operating expenses and working
capital and other requirements, including costs associated with fuel sales;
outlays for the design and construction of new fueling stations; additions or
other modifications to existing fueling stations; RNG production; debt
repayments and repurchases; repurchases of common stock; purchases of CNG tanker
trailers and natural gas heavy-duty trucks; maintenance of LNG production
facilities; supporting our operations, including maintenance and improvements of
our infrastructure; supporting our sales and marketing activities, including
support of legislative and regulatory initiatives; financing natural gas
vehicles for our customers; any investments in other entities; any mergers or
acquisitions; pursuing market expansion as opportunities arise, including
geographically and to new customer markets; and to fund other activities or
pursuits and for other general corporate purposes.

Our business plan originally called for approximately $18.0 million in capital
expenditures for all of 2020. However, due to the impact of COVID-19, we reduced
our anticipated capital expenditures for 2020 to $14.0 million for our core
business. These planned capital expenditures primarily relate to the
construction of CNG fueling stations, IT software and equipment and LNG plant
costs, and we expect to fund these expenditures primarily through cash on hand
and cash generated from operations. We may also deploy capital for investments
in RNG production. For the six months ended June 30, 2020, our capital
expenditures were approximately $4.8 million, and we may not spend the full
$14.0 million in 2020.

In addition, we previously anticipated that NG Advantage may spend as much as
$12.8 million in 2020 for capital expenditures. However, due to the impact of
COVID-19, we reduced NG Advantage's anticipated capital expenditures to $2.0
million. These planned capital expenditures primarily relate to purchases of
additional equipment in support of its operations and customer contracts;
although NG Advantage has sought financing from third parties for capital
expenditures, we have provided and may continue to provide financing for these
capital expenditures. For the six months ended June 30, 2020, NG Advantage's
capital expenditures were approximately $1.5 million, and NG Advantage may not
spend the full $2.0 million in 2020.

We had total indebtedness, consisting of our debt and finance leases, of
approximately $40.4 million in principal amount as of June 30, 2020, of which
approximately $3.4 million, $7.1 million, $7.2 million, $12.3 million, $10.1
million, and $0.3 million is expected to become due in 2020, 2021, 2022, 2023,
2024 and thereafter, respectively. We expect our total interest payment
obligations relating to this indebtedness to be approximately $4.8 million in
2020, $3.3 million of which had been paid when due as of June 30, 2020. We plan
to and are able to make all expected principal and interest payments in the next
12 months.

We also have indebtedness, including the amount representing interest, from our
operating leases of approximately $43.5 million as of June 30, 2020, of which
approximately $2.7 million, $4.6 million, $3.7 million, $3.7 million, $3.7
million and $25.1 million is expected to become due in 2020, 2021, 2022, 2023,
2024 and thereafter, respectively.

In addition, in connection with implementing our Zero Now truck financing
program, we have entered into agreements that permit us to incur a material
amount of additional debt on a delayed draw basis and obligate us to make
interest and other fee payments that vary in amount depending on the outstanding
principal of this debt and certain other factors; none of this potential debt
nor the related interest and other payments are included in the foregoing
estimates, other than the principal amount of $4.6 million drawn as of June 30,
2020.

Although we believe we have sufficient liquidity and capital resources to repay
our debt coming due in the next 12 months, we may elect to pursue alternatives,
such as refinancing or debt or equity offerings, to increase our cash management
flexibility.

We intend to make payments under our various debt instruments when due and pursue opportunities for earlier repayment and/or refinancing if and when these opportunities arise.

Sources of Cash

Historically, our principal sources of liquidity have consisted of cash on hand;
cash provided by our operations, including, if available, AFTC and other
government credits, grants and incentives; cash provided by financing
activities; and sales of assets. As of June 30, 2020, we had total cash and cash
equivalents and short-term investments of $95.7 million, compared to $106.1
million as of December 31, 2019.

We expect cash provided by our operating activities to fluctuate depending on
our operating results, which can be affected by the factors described above, as
well as the other factors described in this MD&A and Part II, Item 1A. Risk
Factors of this report.

In October 2018 and January 2019, we entered into agreements to implement our
Zero Now truck financing program, which permit us to incur up to an additional
$100.0 million of indebtedness through the beginning of January 2022, obligate
us to make certain interest and other fee payments in connection with this debt
and THUSA's related guaranty (which payments will vary in amount but will be
owed by us regardless of the revenue we may receive from the program), and
subject us to potential additional payments in connection with related commodity
swap arrangements. We are permitted to use any proceeds we receive under these
agreements solely to fund the incremental cost of trucks purchased or financed
by operators that participate in the Zero Now program. See Note 12 for more
information.

See Note 12 for more information about all of our outstanding debt.



We believe our cash and cash equivalents and short-term investments and
anticipated cash provided by our operating and financing activities will satisfy
our expected business requirements for at least the 12 months following the date
of this report. Subsequent to that period, we may need to raise additional
capital to fund any planned or unanticipated capital expenditures, investments,
debt repayments, share repurchases or other expenses that we cannot fund through
cash on-hand, cash provided by our operations or other sources. Moreover, we may
use our cash resources faster than we predict due to unexpected expenditures,
the effects of COVID-19 or higher-than-expected expenses, in which case we may
need to seek capital from alternative sources sooner than we anticipate.

The timing and necessity of any future capital raise would depend on various
factors, including our rate and volume of, and prices for, natural gas sales and
other volume-related activity, the effects of COVID-19, new station
construction, debt repayments (either before or at maturity) and any potential
mergers, acquisitions, investments, divestitures or other strategic
relationships we may pursue, as well as the other factors that affect our
revenue and expense levels as described in this MD&A and elsewhere in this
report.

We may seek to raise additional capital through one or more sources, including,
among others, selling assets, obtaining new or restructuring existing debt,
obtaining equity capital, or any combination of these or other potential sources
of capital. We may not be able to raise capital when needed, on terms that are
favorable to us or our stockholders or at all. Any inability to raise necessary
capital may impair our ability to develop and maintain natural gas fueling
infrastructure, invest in strategic transactions or acquisitions or repay our
outstanding indebtedness and may reduce our ability to support and build our
business and generate sustained or increased revenue.

Off-Balance Sheet Arrangements



As of June 30, 2020, we had the following off-balance sheet arrangements that
have had, or are reasonably likely to have, a material current or future effect
on our financial condition, changes in financial condition, revenue or expenses,
results of operations, liquidity, capital expenditures or capital resources:

? Outstanding surety bonds for construction contracts and general corporate

purposes totaling $31.3 million;

? Two long-term natural gas purchase contracts with a take-or-pay commitment;

? Quarterly fixed price natural gas purchase contracts with take-or-pay


   commitments;


                                       39

  Table of Contents

? One long-term natural gas sale contract with a fixed supply commitment along

with a guaranty agreement; and

? One long-term natural gas sale contract with a fixed supply commitment.




We provide surety bonds primarily for construction contracts in the ordinary
course of our business, as a form of guarantee. No liability has been recorded
in connection with our surety bonds because, based on historical experience and
available information, we do not believe it is probable that any amounts will be
required to be paid under these arrangements for which we will not be
reimbursed.

As of June 30, 2020, we had two long-term natural gas purchase contracts with a
take-or-pay commitment, which require us to purchase minimum volumes of natural
gas at index-based prices and expire in December 2020 and June 2022,
respectively. Additionally, as of June 30, 2020, we had quarterly fixed-price
natural gas purchase contracts with take-or-pay commitments extending through
June 2023.

NG Advantage has entered into an arrangement with BP for the supply, sale and
reservation of a specified volume of CNG transportation capacity until
March 2022. In June 2020, we paid BP $7.8 million to terminate a portion of the
forgoing arrangement. In connection with the arrangement, on February 28, 2018,
we entered into a guaranty agreement with NG Advantage and BP in which we
guarantee NG Advantage's payment obligations to BP in the event of a default by
NG Advantage under the supply arrangement, in an aggregate amount of up to $30.0
million plus related fees, which was reduced to $15.0 million effective June 24,
2020. Our guaranty is in effect until thirty days following our notice to BP of
termination.

In addition, as of June 30, 2020, we had a fixed supply arrangement with UPS for the supply and sale of 170.0 million GGEs of RNG through March 2026.
