OVERVIEW



We are an independent petroleum refiner and marketer that produces high-value
light products such as gasoline, diesel fuel, jet fuel, specialty lubricant
products and specialty and modified asphalt. As of September 30, 2021, we owned
and operated refineries located in El Dorado, Kansas (the "El Dorado Refinery"),
Tulsa, Oklahoma (the "Tulsa Refineries"), which comprise two production
facilities, the Tulsa West and East facilities, Artesia, New Mexico, which
operates in conjunction with crude, vacuum distillation and other facilities
situated 65 miles away in Lovington, New Mexico (collectively, the "Navajo
Refinery") and Woods Cross, Utah (the "Woods Cross Refinery"). We market our
refined products principally in the Southwest United States, the Rocky Mountains
extending into the Pacific Northwest and in other neighboring Plains states. In
addition, we produce base oils and other specialized lubricants in the United
States, Canada and the Netherlands, and export products to more than 80
countries. We also own a 57% limited partner interest and a non-economic general
partner interest in HEP, a master limited partnership that provides petroleum
product and crude oil transportation, terminalling, storage and throughput
services to the petroleum industry, including HollyFrontier Corporation
subsidiaries.

On August 2, 2021, HollyFrontier, Hippo Parent Corporation, a wholly owned
subsidiary of HollyFrontier ("New Parent"), Hippo Merger Sub, Inc., a wholly
owned subsidiary of New Parent ("Parent Merger Sub"), The Sinclair Companies
("Sinclair"), and Hippo Holding LLC, a wholly owned subsidiary of Sinclair (the
"Target Company"), entered into a business combination agreement (the "Business
Combination Agreement"). Pursuant to the Business Combination Agreement,
HollyFrontier will acquire the Target Company by effecting (a) a holding company
merger in accordance with Section 251(g) of the Delaware General Corporation Law
whereby HollyFrontier will merge with and into Parent Merger Sub, with
HollyFrontier surviving such merger as a direct wholly owned subsidiary of New
Parent (the "HFC Merger") and (b) immediately following the HFC Merger, a
contribution whereby Sinclair will contribute all of the equity interests of the
Target Company to New Parent in exchange for shares of New Parent, resulting in
the Target Company becoming a direct wholly owned subsidiary of New Parent (the
"Sinclair Oil Acquisition" and together with the HFC Merger, the "HFC
Transactions").

Under the terms of the Business Combination Agreement, (a) each share of common
stock of HollyFrontier, par value $0.01 per share, will be automatically
converted into one share of common stock of New Parent, par value $0.01 per
share ("New Parent Common Stock") and (b) Sinclair will contribute the equity
interests in the Target Company to New Parent in exchange for 60,230,036 shares
of New Parent Common Stock, subject to adjustment if, as a condition to
obtaining antitrust clearance for the Sinclair Transactions (as defined below),
HollyFrontier agrees to divest certain Woods Cross Refinery assets and the sales
price for such assets does not exceed a threshold provided in the Business
Combination Agreement.

Additionally, on August 2, 2021, HEP, Sinclair and Sinclair Transportation
Company, a wholly owned subsidiary of Sinclair ("STC"), entered into a
contribution agreement (the "Contribution Agreement") pursuant to which HEP will
acquire all of the outstanding shares of STC in exchange for 21 million newly
issued common limited partner units of HEP and cash consideration equal to $325
million (the "HEP Transactions", and together with the HFC Transactions, the
"Sinclair Transactions"), subject to downward adjustment if, as a condition to
obtaining antitrust clearance for the Sinclair Transactions, HEP agrees to
divest a portion of its equity interest in UNEV Pipeline, LLC and the sales
price for such interests does not exceed the threshold provided in the
Contribution Agreement.

The Sinclair Transactions are expected to close in mid-2022, subject to
customary closing conditions and regulatory clearance, including the expiration
or termination of the waiting period under the Hart-Scott-Rodino Antitrust
Improvements Act ("HSR Act") and the receipt of required approvals of HFC's
stockholders. On August 23, 2021, each of HollyFrontier and Sinclair filed its
respective premerger notification and report regarding the Sinclair Transactions
with the U.S. Department of Justice and the U.S. Federal Trade Commission (the
"FTC") under the HSR Act. On September 22, 2021, HollyFrontier and Sinclair each
received a request for additional information and documentary material ("Second
Request") from the FTC in connection with the FTC's review of the Sinclair
Transactions. Issuance of the Second Request extends the waiting period under
the HSR Act until 30 days after both HollyFrontier and Sinclair have
substantially complied with the Second Request, unless the waiting period is
terminated earlier by the FTC or the parties otherwise commit not to close the
Sinclair Transactions for some additional period of time. HollyFrontier and
Sinclair are cooperating with the FTC staff in its review. In addition, the HFC
Transactions and the HEP Transactions are cross-conditioned on each other. See
Note 2 "Acquisitions" in the Notes to Consolidated Financial Statements for
additional information.

On May 4, 2021, our wholly owned subsidiary, HollyFrontier Puget Sound Refining
LLC, entered into a sale and purchase agreement with Equilon Enterprises LLC
d/b/a Shell Oil Products US ("Shell") to acquire Shell's refinery and related
assets, including the on-site cogeneration facility and related logistics assets
(the "Puget Sound Refinery"). The acquisition closed on November 1, 2021 for
aggregate cash consideration of $613.6 million, which consists of a base cash
purchase price of $350 million, hydrocarbon inventory with an estimated closing
value of $266.2 million and other closing adjustments and accrued liabilities of
$2.6 million (the "Puget Sound Acquisition"). The Puget Sound Refinery is
strategically located on approximately 850 acres in Anacortes, Washington,
approximately 80 miles north of Seattle and 90 miles south of Vancouver. The
149,000 barrel per day facility is a large, high quality and complex refinery
with catalytic cracking and delayed coking units and is well positioned
geographically and logistically to source advantaged Canadian and Alaskan North
Slope crudes. In addition to refining assets and an on-site cogeneration
facility, the transaction includes a deep-water marine dock, a light product
loading rack, a rail terminal, and storage tanks with approximately 5.8 million
barrels of crude, product and other hydrocarbon storage capacity.

On April 27, 2021, our wholly owned subsidiary, 7037619 Canada Inc., entered
into a contract for sale of real property in Mississauga, Ontario for base
consideration of $98.8 million, or CAD 125 million. The transaction closed on
September 15, 2021, and we recorded a gain on sale of assets totaling
$86.0 million for the three months ended September 30, 2021, which was
recognized in "Gain on sale of assets and other" in our consolidated statements
of operations.

In the third quarter of 2020, we permanently ceased petroleum refining
operations at our facility in Cheyenne, Wyoming (the "Cheyenne Refinery") and
subsequently began converting certain assets at our Cheyenne Refinery to
renewable diesel production. In connection with the cessation of petroleum
refining operations at our Cheyenne Refinery, we recognized $6.7 million and
$23.1 million, respectively, in decommissioning expense and $0.2 million and
$0.9 million, respectively, in employee severance costs for the three and nine
months ended September 30, 2021 which were recognized in operating expenses in
our Corporate and Other segment.

During the first quarter of 2021, we initiated a restructuring within our
Lubricants and Specialty Products segment, which is expected to save
approximately $15 million per year of ongoing cash expenses. We recorded $7.8
million in employee severance costs for the nine months ended September 30,
2021, which were recognized primarily as selling, general and administrative
expenses in our Lubricants and Specialty Products segment.

For the three months ended September 30, 2021, net income attributable to
HollyFrontier stockholders was $280.8 million compared to net loss of $2.4
million for the three months ended September 30, 2020. For the nine months ended
September 30, 2021, net income attributable to HollyFrontier stockholders was
$597.9 million compared to net loss of $483.7 million for the nine months ended
September 30, 2020. Included in our financial results for the third quarter of
2021 was a gain on sale of assets totaling $86.0 million related to sale of real
property in Mississauga, Ontario. Gross refining margin per produced barrel sold
in our Refining segment increased 140% for the three months ended September 30,
2021 over the same period of 2020. Included in the three months ended
September 30, 2020 was an $81.0 million gain recognized upon settlement of a
business interruption insurance claim.

Pursuant to the 2007 Energy Independence and Security Act, the Environmental
Protection Agency ("EPA") promulgated the Renewable Fuel Standard ("RFS")
regulations, which increased the volume of renewable fuels mandated to be
blended into the nation's fuel supply. The regulations, in part, require
refiners to add annually increasing amounts of "renewable fuels" to their
petroleum products or purchase credits, known as renewable identification
numbers ("RINs"), in lieu of such blending. Compliance with RFS regulations
significantly increases our cost of products sold, with RINs costs totaling
$143.5 million for the three months ended September 30, 2021. At September 30,
2021, our open RINs credit obligations were $119.6 million. We will continue to
monitor and adjust our RINs position commensurate with our production levels,
market conditions and RFS regulations.

Impact of COVID-19 on Our Business
The COVID-19 pandemic caused a decline in U.S. and global economic activity
starting in the first quarter of 2020. This decrease reduced both volumes and
unit margins across our businesses, resulting in lower gross margins and
earnings. Global demand for transportation fuels began to improve beginning late
in the second quarter of 2020, but remains below pre-pandemic levels as of the
third quarter of 2021. In response to this demand and margin environment, as
well as both planned and unplanned maintenance, we operated our Refining segment
refineries at an average crude charge of 416,430 BPD during the third quarter of
2021.

In our Lubricants and Specialty Products segment, the Rack Back portion
continues to see a combination of strong demand as well as limited supply due to
a number of factors, which are driving strong margins and earnings. In the Rack
Forward portion, despite strong sales volumes and price increases, the continued
rise in base oil prices through the quarter compressed margins in the third
quarter of 2021.

Our standalone (excluding HEP) liquidity was approximately $2.8 billion at
September 30, 2021, consisting of cash and cash equivalents of $1.5 billion and
an undrawn $1.35 billion credit facility maturing in 2026. Our standalone
(excluding HEP) principal amount of long-term debt was $1.75 billion as of
September 30, 2021, which consists of $350.0 million in aggregate principal
amount of 2.625% senior notes due in 2023, $1.0 billion in aggregate principal
amount of 5.875% senior notes due in 2026 and $400.0 million in aggregate
principal amount of 4.500% senior notes due in 2030.


OUTLOOK



The impact of the COVID-19 pandemic on the global macroeconomy created an
unprecedented reduction in demand, as well as a lack of forward visibility, for
many of the transportation fuels, lubricants and specialty products and the
associated transportation and terminal services we provide. Since the declines
in demand at the beginning of the COVID-19 pandemic, we began to see improvement
in demand for these products and services beginning late in the second quarter
of 2020 and demand has largely recovered in the markets we serve but remains
below pre-pandemic levels.

With increasing vaccination rates, most of our employees have returned to work
at our locations, and we continue to follow Centers for Disease Control and
local government guidance. We will continue to monitor developments in the
COVID-19 pandemic and the dynamic environment it has created to properly address
these policies going forward.

Within our Refining segment, for the fourth quarter of 2021, we expect to run
between 450,000-470,000 barrels per day of crude oil, which includes expected
volumes from the Puget Sound Refinery in November and December. We expect to
adjust refinery production levels commensurate with market demand and planned
turnarounds at our Tulsa and Navajo refineries.

Within our Lubricants and Specialty Products segment, for the full year 2021, we
expect to earn between $65 million to $85 million in income from operations and
$115 million to $135 million of EBITDA, which excludes estimated annual
depreciation of $50 million, in the Rack Forward portion of the segment. Within
the Rack Back portion, for the fourth quarter of 2021, we expect base oil
margins to remain relatively stable compared to the second and third quarters
due to record strength in base oil prices, which is driving strong margins and
earnings. Similar to our Refining segment, we expect to adjust production levels
commensurate with market demand.

In the fourth quarter of 2021, HEP expects to hold the quarterly distribution
constant at $0.35 per unit, or $1.40 on an annualized basis. HEP remains
committed to its distribution strategy focused on funding all capital
expenditures and distributions within operating cash flow and improving
distributable cash flow coverage to 1.3x or greater with the goal of reducing
leverage to 3.0-3.5x.

During the third quarter of 2020, we increased our liquidity by $750.0 million
with the issuance of $350.0 million in aggregate principal amount of 2.625%
senior notes due in 2023 and $400.0 million in aggregate principal amount of
4.500% senior notes due in 2030. This additional liquidity may be used for
general corporate purposes and is expected to support the planned growth of our
renewables business and the unexpected economic impact of COVID-19, as needed.
We do not intend to repurchase common stock under our $1.0 billion share
repurchase program until completion of our ongoing renewables capital projects
at the earliest. In addition, we announced the Puget Sound Acquisition, which
closed on November 1, 2021. We funded the Puget Sound Acquisition with a
one-year suspension of our regular quarterly dividend and cash on hand. Our
Board of Directors approved the one-year suspension of the regular quarterly
dividend effective with the dividend to be declared for the first quarter of
2021 and is expected to resume the dividend after such time.

On March 27, 2020, the U.S. government passed the Coronavirus Aid, Relief, and
Economic Security Act (the "CARES Act"), an approximately $2 trillion stimulus
package that included various provisions intended to provide relief to
individuals and businesses in the form of tax changes, loans and grants, among
others. At this time, we have not sought relief in the form of loans or grants
from the CARES Act; however, we have benefited from certain tax deferrals in the
CARES Act and may benefit from other tax provisions if we meet the requirements
to do so.

The extent to which our future results are affected by the COVID-19 pandemic
will depend on various factors and consequences beyond our control, such as the
duration and scope of the pandemic, the effects of any new variant strains of
the underlying virus, additional actions by businesses and governments in
response to the pandemic and the speed and effectiveness of responses to combat
the virus. The COVID-19 pandemic, and the volatile regional and global economic
conditions stemming from it, could also exacerbate the risk factors identified
in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020,
in our Quarterly Report on Form 10-Q for the quarters ended March 31, 2021 and
June 30, 2021 and in this Form 10-Q. The COVID-19 pandemic may also materially
adversely affect our results in a manner that is either not currently known or
that we do not currently consider to be a significant risk to our business.

A more detailed discussion of our financial and operating results for the three
and nine months ended September 30, 2021 and 2020 is presented in the following
sections.

(1)Earnings before interest, taxes, depreciation and amortization, which we
refer to as "EBITDA," is calculated as net income (loss) attributable to
HollyFrontier stockholders plus (i) interest expense, net of interest income,
(ii) income tax provision, and (iii) depreciation and amortization. EBITDA is
not a calculation provided for under GAAP; however, the amounts included in the
EBITDA calculation are derived from amounts included in our consolidated
financial statements. EBITDA should not be considered as an alternative to net
income or operating income as an indication of our operating performance or as
an alternative to operating cash flow as a measure of liquidity. EBITDA is not
necessarily comparable to similarly titled measures of other companies. EBITDA
is presented here because it is a widely used financial indicator used by
investors and analysts to measure performance. EBITDA is also used by our
management for internal analysis and as a basis for financial covenants. EBITDA
presented above is reconciled to net income under "Reconciliations to Amounts
Reported Under Generally Accepted Accounting Principles" following Item 3 of
Part I of this Form 10-Q.

Segment Operating Data

Our operations are organized into three reportable segments, Refining,
Lubricants and Specialty Products and HEP. See Note 15 "Segment Information" in
the Notes to Consolidated Financial Statements for additional information on our
reportable segments.

Refining Segment Operating Data



As of September 30, 2021, our refinery operations include the El Dorado, Tulsa,
Navajo and Woods Cross Refineries. The following tables set forth information,
including non-GAAP performance measures, about our consolidated refinery
operations. The cost of products and refinery gross and net operating margins do
not include the non-cash effects of lower of cost or market inventory valuation
adjustments, depreciation and amortization and long-lived asset impairments.
Reconciliations to amounts reported under GAAP are provided under
"Reconciliations to Amounts Reported Under Generally Accepted Accounting
Principles" following Item 3 of Part I of this Form 10-Q.

In the third quarter of 2020, we permanently ceased petroleum refining
operations at our Cheyenne Refinery and subsequently began converting certain
assets at our Cheyenne Refinery to renewable diesel production. The
disaggregation of our refining geographic operating data is presented in two
regions, Mid-Continent and West, to best reflect the economic drivers of our
refining operations. The Mid-Continent region continues to be comprised of the
El Dorado and Tulsa Refineries, and the new West region is comprised of the
Navajo and Woods Cross Refineries. Refining segment operating data for the three
and nine months ended September 30, 2020 have been retrospectively adjusted to
reflect the revised regional groupings.

Results of Operations - Three Months Ended September 30, 2021 Compared to Three Months Ended September 30, 2020

Summary


Net income attributable to HollyFrontier stockholders for the three months ended
September 30, 2021 was $280.8 million ($1.71 per basic and diluted share), a
$283.2 million increase from a net loss of $2.4 million ($(0.01) per basic and
diluted share) for the three months ended September 30, 2020. The increase in
net income was principally driven by stronger product demand, which resulted in
an increase in refinery gross margins and higher refined product sales volumes.
Refinery gross margins for the three months ended September 30, 2021 increased
to $14.87 per produced barrel sold from $6.20 for the three months ended
September 30, 2020. This increase was partially offset by the lower of cost or
market inventory reserve adjustment that increased pre-tax earnings by $62.8
million for the three months ended September 30, 2020.

Sales and Other Revenues
Sales and other revenues increased 66% from $2,819.4 million for the three
months ended September 30, 2020 to $4,685.1 million for the three months ended
September 30, 2021 principally due to the increase in sales prices and higher
refined product sales volumes. Sales and other revenues for the three months
ended September 30, 2021 and 2020 included $25.5 million and $26.7 million,
respectively, of HEP revenues attributable to pipeline and transportation
services provided to unaffiliated parties. Additionally, sales and other
revenues included $666.0 million and $452.9 million in unaffiliated revenues
related to our Lubricants and Specialty Products segment for the three months
ended September 30, 2021 and 2020, respectively.

Cost of Products Sold
Total cost of products sold increased 65% from $2,314.4 million for the three
months ended September 30, 2020 to $3,822.9 million for the three months ended
September 30, 2021 principally due to higher crude oil costs and higher refined
product sales volumes. During the third quarter of 2020, we recognized a lower
of cost or market inventory valuation adjustment benefit of $62.8 million.

Gross Refinery Margins
Gross refinery margin per produced barrel sold increased 140% from $6.20 for the
three months ended September 30, 2020 to $14.87 for the three months ended
September 30, 2021. The increase was due to the effects of an increase in the
average per barrel sold sales price during the current year quarter, partially
offset by increased crude oil and feedstock prices. Gross refinery margin per
barrel does not include the non-cash effects of lower of cost or market
inventory valuation adjustments or depreciation and amortization. See
"Reconciliations to Amounts Reported Under Generally Accepted Accounting
Principles" following Item 3 of Part I of this Form 10-Q for a reconciliation to
the income statement of sale prices of products sold and cost of products
purchased.

Operating Expenses
Operating expenses, exclusive of depreciation and amortization, increased 6%
from $332.5 million for the three months ended September 30, 2020 to $352.5
million for the three months ended September 30, 2021 primarily due to an
increase in natural gas prices.

Selling, General and Administrative Expenses
Selling, general and administrative expenses increased 22% from $74.5 million
for the three months ended September 30, 2020 to $91.1 million for the three
months ended September 30, 2021 primarily due to higher professional services
and legal costs incurred in connection with the recently announced acquisitions,
including $4.3 million in pre-close acquisition integration costs related to the
Puget Sound Acquisition during the three months ended September 30, 2021. See
Note 2 "Acquisitions" in the Notes to Consolidated Financial Statements for
additional information on these acquisitions.

Depreciation and Amortization Expenses
Depreciation and amortization decreased 3% from $125.3 million for the three
months ended September 30, 2020 to $121.2 million for the three months ended
September 30, 2021. This decrease was primarily due to lower capitalized
refinery turnaround costs during 2020.

                                       49
--------------------------------------------------------------------------------
  Table of Content
Interest Expense
Interest expense was $26.9 million for the three months ended September 30, 2021
compared to $30.6 million for the three months ended September 30, 2020. This
decrease was primarily due to net gains related to our catalyst financing
arrangement during the three months ended September 30, 2021 as compared to net
losses during the same period in the prior year and higher capitalized interest
during the three months ended September 30, 2021 due to the capital expenditures
related to the construction of our renewable diesel units. This decrease was
partially offset by interest expense on our senior notes issued in September
2020.

For the three months ended September 30, 2021 and 2020, interest expense attributable to our HEP segment was $13.4 million and $12.5 million, respectively.



Gain on Business Interruption Insurance Settlement
During the third quarter of 2020, we recorded a gain of $81.0 million upon the
settlement of our business interruption claim with our insurance carrier related
to a loss at our Woods Cross Refinery that occurred in the first quarter of
2018.

Gain (Loss) on Foreign Currency Transactions
Remeasurement adjustments resulting from the foreign currency conversion of the
intercompany financing notes payable by PCLI net of mark-to-market valuations on
foreign exchange forward contracts with banks which hedge the foreign currency
exposure on these intercompany notes was a net loss of $3.5 million and a net
gain of $1.0 million for the three months ended September 30, 2021 and 2020,
respectively. For the three months ended September 30, 2021 and 2020, gain
(loss) on foreign currency transactions included a gain of $9.7 million and a
loss of $8.2 million, respectively, on foreign exchange forward contracts
(utilized as an economic hedge).

Gain on Sale of Assets and Other
For the three months ended September 30, 2021, we recorded an $86.0 million gain
related to the sale of real property in Mississauga, Ontario. See Note 1
"Description of Business and Presentation of Financial Statements" in the Notes
to Consolidated Financial Statements for additional information.

Income Taxes
For the three months ended September 30, 2021, we recorded an income tax expense
of $54.8 million compared to $4.6 million for the three months ended
September 30, 2020. This increase was principally due to higher pre-tax income
during the three months ended September 30, 2021 compared to the same period of
2020. Our effective tax rates were 15.3% and 16.4% for the three months ended
September 30, 2021 and 2020, respectively. The decrease in the effective tax
rate is principally due to the relationship between the pre-tax results and the
earnings attributable to the noncontrolling interest that is not included in
income for tax purposes. The difference in the U.S. federal statutory rate and
the effective tax rate for the three months ended September 30, 2021 was
primarily due to the net operating loss carryback provisions of the CARES Act
and federal tax credits.


Results of Operations - Nine Months Ended September 30, 2021 Compared to Nine Months Ended September 30, 2020

Summary


Net income attributable to HollyFrontier stockholders for the nine months ended
September 30, 2021 was $597.9 million ($3.63 per basic and diluted share), a
$1,081.6 million increase compared to a net loss of $483.7 million ($(2.99) per
basic and diluted share) for the nine months ended September 30, 2020. The
increase in net income was principally driven by stronger product demand, which
resulted in an increase in refinery gross margins and higher refined product
sales volumes. Net income also increased due to lower of cost or market
inventory reserve adjustments that increased pre-tax earnings by $318.9 million
for the nine months ended September 30, 2021 and decreased pre-tax earnings by
$227.7 million for the nine months ended September 30, 2020. In addition, we
recorded long-lived asset impairment charges of $436.9 million for the nine
months ended September 30, 2020. The increase in net income for the nine months
ended September 30, 2021 was partially offset by the impact of winter storm Uri,
which increased natural gas costs by approximately $65 million across our
refining system. Refinery gross margins for the nine months ended September 30,
2021 increased to $11.75 per barrel sold from $8.50 for the nine months ended
September 30, 2020.

Sales and Other Revenues
Sales and other revenues increased 54% from $8,282.9 million for the nine months
ended September 30, 2020 to $12,766.5 million for the nine months ended
September 30, 2021 due to a year-over-year increase in sales prices and higher
refined product sales volumes. Sales and other revenues for the nine months
ended September 30, 2021 and 2020 include $77.8 million and $72.4 million,
respectively, in HEP revenues attributable to pipeline and transportation
services provided to unaffiliated parties. Additionally, sales and other
revenues included $1,850.8 million and $1,330.0 million in unaffiliated revenues
related to our Lubricants and Specialty Products segment for the nine months
ended September 30, 2021 and 2020, respectively.

Cost of Products Sold
Total cost of products sold increased 50% from $6,875.7 million for the nine
months ended September 30, 2020 to $10,290.0 million for the nine months ended
September 30, 2021 principally due to the increase in crude oil and feedstock
prices and refined product sales volumes. We recognized a lower of cost or
market inventory valuation benefit of $318.9 million for the nine months ended
September 30, 2021 compared to a charge of $227.7 million for the same period of
2020, resulting in no lower of cost or market reserve at September 30, 2021.

Gross Refinery Margins
Gross refinery margin per barrel sold increased 38% from $8.50 for the nine
months ended September 30, 2020 to $11.75 for the nine months ended
September 30, 2021 principally due to the increase in the average per barrel
sold sales prices, partially offset by the increase in crude oil and feedstock
prices. Gross refinery margin per barrel does not include the non-cash effects
of lower of cost or market inventory valuation adjustments or depreciation and
amortization. See "Reconciliations to Amounts Reported Under Generally Accepted
Accounting Principles" following Item 3 of Part I of this Form 10-Q for a
reconciliation to the income statement of sales prices of products sold and cost
of products purchased.

Operating Expenses
Operating expenses, exclusive of depreciation and amortization, increased 13%
from $964.2 million for the nine months ended September 30, 2020 to $1,086.6
million for the nine months ended September 30, 2021 primarily due to the
increase in natural gas prices and higher planned and unplanned repair and
maintenance costs. The increase in natural gas prices was due in part to winter
storm Uri during the first quarter of 2021.

Selling, General and Administrative Expenses
Selling, general and administrative expenses increased 6% from $237.6 million
for the nine months ended September 30, 2020 to $250.8 million for the nine
months ended September 30, 2021 primarily due to higher professional services
and legal costs incurred in connection with the recently announced acquisitions,
including $5.0 million in pre-close acquisition integration costs related to the
Puget Sound Acquisition during the nine months ended September 30, 2021. See
Note 2 "Acquisitions" in the Notes to Consolidated Financial Statements for
additional information on these acquisitions.

Depreciation and Amortization Expenses
Depreciation and amortization decreased 7% from $396.0 million for the nine
months ended September 30, 2020 to $369.3 million for the nine months ended
September 30, 2021. This decrease was principally due to lower capitalized
refinery turnaround costs during 2020 and lower depreciation expense resulting
from the assets impaired in the second quarter of 2020.

Long-lived Asset Impairment
During the nine months ended September 30, 2020, we recorded long-lived asset
impairment charges of $232.2 million that related to our Cheyenne Refinery and
$204.7 million related to PCLI. See Note 1 "Description of Business and
Presentation of Financial Statements" in the Notes to Consolidated Financial
Statements for additional information on these impairments.

Interest Expense
Interest expense was $94.2 million for the nine months ended September 30, 2021
compared to $85.9 million for the nine months ended September 30, 2020. This
increase was primarily due to interest expense on our senior notes issued in
September 2020. This increase was partially offset by higher capitalized
interest during the nine months ended September 30, 2020 due to the capital
expenditures related to the construction of our renewable diesel units and lower
weighted average balance on HEP's credit facility during the nine months ended
September 30, 2021.

For the nine months ended September 30, 2021 and 2020, interest expense attributable to our HEP Segment was $40.6 million and $40.7 million, respectively.



Gain on Business Interruption Insurance Settlement
During the third quarter of 2020, we recorded a gain of $81.0 million upon the
settlement of our business interruption claim with our insurance carrier related
to a loss at our Woods Cross Refinery that occurred in the first quarter of
2018.

Gain on Tariff Settlement
For the nine months ended September 30, 2021, we recorded a gain of $51.5
million upon the settlement of a tariff rate case. See Note 14 "Contingencies"
in the Notes to Consolidated Financial Statements for additional information on
this case and settlement.

Gain on Sales-type Leases
During the second quarter of 2020, HEP and Delek US Holdings, Inc. renewed the
original throughput agreement on specific HEP assets. Portions of the new
throughput agreement met the definition of sales-type leases, which resulted in
an accounting gain of $33.8 million upon the initial recognition of the
sales-type lease during the nine months ended September 30, 2020.

Loss on Early Extinguishment of Debt
For the nine months ended September 30, 2020, HEP recorded a $25.9 million loss
on the redemption of its $500 million aggregate principal amount of 6.0% senior
notes maturing August 2024 for $522.5 million.

Loss on Foreign Currency Transactions
Remeasurement adjustments resulting from the foreign currency conversion of the
intercompany financing notes payable by PCLI net of mark-to-market valuations on
foreign exchange forward contracts with banks which hedge the foreign currency
exposure on these intercompany notes were net losses of $4.2 million and $0.9
million for the nine months ended September 30, 2021 and 2020, respectively. For
the nine months ended September 30, 2021 and 2020, loss on foreign currency
transactions included a net loss of $3.2 million and a gain of $11.0 million,
respectively, on foreign exchange forward contracts (utilized as an economic
hedge).

Gain on Sale of Assets and Other
For the nine months ended September 30, 2021, we recorded an $86.0 million gain
related to the sale of real property in Mississauga, Ontario, and HEP recorded a
$5.3 million gain related to the sale of certain pipeline assets. See Note 1
"Description of Business and Presentation of Financial Statements" in the Notes
to Consolidated Financial Statements for additional information.

Income Taxes
For the nine months ended September 30, 2021, we recorded an income tax expense
of $149.9 million compared to a benefit of $188.5 million for the nine months
ended September 30, 2020. This change to income tax expense in 2021 from income
tax benefit in 2020 was principally due to pre-tax income during the nine months
ended September 30, 2021 as compared to a pre-tax loss in the same period of
2020. Our effective tax rates were 18.1% and 31.0% for the nine months ended
September 30, 2021 and 2020, respectively. The year-over-year decrease in the
effective tax rate is principally due to the relationship between the pre-tax
results and the earnings attributable to the noncontrolling interest that is not
included in income for tax purposes. The difference in the U.S. federal
statutory rate and the effective tax rate for the nine months ended
September 30, 2021 was primarily due to the net operating loss carryback
provisions of the CARES Act and federal tax credits.


LIQUIDITY AND CAPITAL RESOURCES



HollyFrontier Credit Agreement
On April 30, 2021, we amended our $1.35 billion senior unsecured revolving
credit facility to extend the maturity date to April 30, 2026 (the
"HollyFrontier Credit Agreement"). The HollyFrontier Credit Agreement may be
used for revolving credit loans and letters of credit from time to time and is
available to fund general corporate purposes. At September 30, 2021, we were in
compliance with all covenants, had no outstanding borrowings and had outstanding
letters of credit totaling $2.3 million under the HollyFrontier Credit
Agreement.

HollyFrontier Financing Arrangements
Certain of our wholly owned subsidiaries entered into financing arrangements
whereby such subsidiaries sold a portion of their precious metals catalyst to a
financial institution and then leased back the precious metals catalyst in
exchange for cash. The volume of the precious metals catalyst and the lease rate
are fixed over the term of each lease, and the lease payments are recorded as
interest expense. The current leases mature on February 1, 2022. Upon maturity,
we must either satisfy the obligation at fair market value or refinance to
extend the maturity.

HEP Credit Agreement
On April 30, 2021, HEP amended its $1.4 billion senior secured revolving credit
facility decreasing the commitments under the facility to $1.2 billion and
extending the maturity to July 27, 2025 (the "HEP Credit Agreement"). The HEP
Credit Agreement is available to fund capital expenditures, investments,
acquisitions, distribution payments, working capital and for general partnership
purposes. It is also available to fund letters of credit up to a $50 million
sub-limit and continues to provide for an accordion feature that allows HEP to
increase the commitments under the HEP Credit Agreement up to a maximum amount
of $1.7 billion. During the nine months ended September 30, 2021, HEP received
advances totaling $210.5 million and repaid $283.5 million under the HEP Credit
Agreement. At September 30, 2021, HEP was in compliance with all of its
covenants, had outstanding borrowings of $840.5 million and no outstanding
letters of credit under the HEP Credit Agreement.

See Note 10 "Debt" in the Notes to Consolidated Financial Statements for additional information on our debt instruments.

Liquidity


We believe our current cash and cash equivalents, along with future internally
generated cash flow and funds available under our credit facilities, will
provide sufficient resources to fund currently planned capital projects and our
liquidity needs for the foreseeable future. We expect that, to the extent
necessary, we can raise additional funds from time to time through equity or
debt financings in the public and private capital markets. In addition,
components of our long-term growth strategy include the expansion of existing
units at our facilities and selective acquisition of complementary assets for
our refining operations intended to increase earnings and cash flow. In
connection with the Puget Sound Acquisition, our Board of Directors approved a
one-year suspension of the regular quarterly dividend effective with the
dividend to be declared for the first quarter of 2021 and is expected to resume
the dividend after such time.

Our standalone (excluding HEP) liquidity was approximately $2.8 billion at September 30, 2021, consisting of cash and cash equivalents of $1.5 billion and an undrawn $1.35 billion credit facility.



We consider all highly-liquid instruments with a maturity of three months or
less at the time of purchase to be cash equivalents. These primarily consist of
investments in conservative, highly-rated instruments issued by financial
institutions, government and corporate entities with strong credit standings and
money market funds. Cash equivalents are stated at cost, which approximates
market value.

In November 2019, our Board of Directors approved a $1.0 billion share
repurchase program, which replaced all existing share repurchase programs,
authorizing us to repurchase common stock in the open market or through
privately negotiated transactions. The timing and amount of stock repurchases
will depend on market conditions and corporate, regulatory and other relevant
considerations. This program may be discontinued at any time by the Board of
Directors. As of September 30, 2021, we had not repurchased common stock under
this stock repurchase program. In addition, we are authorized by our Board of
Directors to repurchase shares in an amount sufficient to offset shares issued
under our compensation programs. We do not intend to repurchase common stock
under our $1.0 billion share repurchase program until completion of our ongoing
renewables capital projects at the earliest.
Cash Flows - Operating Activities

Nine Months Ended September 30, 2021 Compared to Nine Months Ended September 30,
2020
Net cash flows provided by operating activities were $739.5 million for the nine
months ended September 30, 2021 compared to $391.1 million for the nine months
ended September 30, 2020, an increase of $348.4 million. The increase in
operating cash flows was primarily due to the increase in gross refinery margins
and $51.5 million received upon settlement of a tariff rate case, partially
offset by higher operating expenses.

Changes in working capital increased operating cash flows by $55.3 million and decreased operating cash flows by $50.0 million, for the nine months ended September 30, 2021 and 2020, respectively. Changes in working capital items adjust for the timing of receipts and payments of actual cash.

Cash Flows - Investing Activities and Planned Capital Expenditures

Nine Months Ended September 30, 2021 Compared to Nine Months Ended September 30,
2020
Net cash flows used for investing activities were $438.5 million for the nine
months ended September 30, 2021 compared to $213.7 million for the nine months
ended September 30, 2020, an increase of $224.8 million. Cash expenditures for
properties, plants and equipment for the nine months of 2021 increased to $548.3
million from $213.0 million for the same period in 2020, primarily due to
expenditures related to our renewable diesel units that are expected to be
completed in the first half of 2022. Cash expenditures for properties, plants
and equipment include HEP capital expenditures of $76.9 million and $38.6
million for the nine months ended September 30, 2021 and 2020, respectively. For
the nine months ended September 30, 2020, HEP also invested $2.4 million in the
Cushing Connect Pipeline & Terminal LLC joint venture.

HollyFrontier Corporation
Each year our Board of Directors approves our annual capital budget which
includes specific projects that management is authorized to undertake.
Additionally, when conditions warrant or as new opportunities arise, additional
projects may be approved. The funds appropriated for a particular capital
project may be expended over a period of several years, depending on the time
required to complete the project. Therefore, our planned capital expenditures
for a given year consist of expenditures appropriated in that year's capital
budget plus expenditures for projects appropriated in prior years which have not
yet been completed. Refinery turnaround spending is amortized over the useful
life of the turnaround.

The refining industry is capital intensive and requires on-going investments to
sustain our refining operations. This includes replacement of, or rebuilding,
refinery units and components that extend the useful life. We also invest in
projects that improve operational reliability and profitability via enhancements
that improve refinery processing capabilities as well as production yield and
flexibility. Our capital expenditures also include projects related to renewable
diesel, environmental, health and safety compliance and include initiatives as a
result of federal and state mandates.

Our refinery operations and related emissions are highly regulated at both
federal and state levels, and we invest in our facilities as needed to remain in
compliance with these standards. Additionally, when faced with new emissions or
fuels standards, we seek to execute projects that facilitate compliance and also
improve the operating costs and / or yields of associated refining processes.

HEP


Each year the Holly Logistic Services, L.L.C. board of directors approves HEP's
annual capital budget, which specifies capital projects that HEP management is
authorized to undertake. Additionally, at times when conditions warrant or as
new opportunities arise, special projects may be approved. The funds allocated
for a particular capital project may be expended over a period in excess of a
year, depending on the time required to complete the project. Therefore, HEP's
planned capital expenditures for a given year consist of expenditures approved
for capital projects included in its current year capital budget as well as, in
certain cases, expenditures approved for capital projects in capital budgets for
prior years. In addition, HEP may spend funds periodically to perform capital
upgrades or additions to its assets where a customer reimburses HEP for such
costs. The upgrades or additions would generally benefit the customer over the
remaining life of the related service agreements.

Expected capital and turnaround cash spending for 2021 is as follows and
primarily reflects a change in the timing of spend between 2021 and 2022 on the
renewable diesel units.

Contractual Obligations and Commitments

HollyFrontier Corporation



In April 2021, we renewed a contract for terminal and storage services with a
third party for an additional 15-year term. The agreement provides for storage
capacity of 200,000 barrels per month for a total commitment of $9.4 million
over the 15 year term. In addition, the agreement provides a throughput volume
commitment of 225,000 barrels per day of crude oil for a total commitment of
$92.4 million over the 15-year term. We also had certain lease renewals that
increased our lease liabilities on our consolidated balance sheets during the
nine months ended September 30, 2021. There were no other significant changes to
our long-term contractual obligations during the nine months ended September 30,
2021.

HEP

During the nine months ended September 30, 2021, HEP had net repayments of $73.0 million resulting in $840.5 million of outstanding borrowings under the HEP Credit Agreement at September 30, 2021.

There were no other significant changes to HEP's long-term contractual obligations during this period.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES



Our discussion and analysis of our financial condition and results of operations
are based upon our consolidated financial statements, which have been prepared
in accordance with accounting principles generally accepted in the United
States. The preparation of these financial statements requires us to make
estimates and judgments that affect the reported amounts of assets, liabilities,
revenues and expenses, and related disclosure of contingent assets and
liabilities as of the date of the financial statements. Actual results may
differ from these estimates under different assumptions or conditions.

Our significant accounting policies are described in "Part II, Item 7.
Management's Discussion and Analysis of Financial Condition and Results of
Operations - Critical Accounting Policies" in our Annual Report on Form 10-K for
the year ended December 31, 2020. Certain critical accounting policies that
materially affect the amounts recorded in our consolidated financial statements
include the use of the last-in, first-out ("LIFO") method of valuing certain
inventories, assessing the possible impairment of certain long-lived assets and
goodwill, and assessing contingent liabilities for probable losses.

Inventory Valuation: Inventories related to our refining operations are stated
at the lower of cost, using the LIFO method for crude oil and unfinished and
finished refined products, or market. In periods of rapidly declining prices,
LIFO inventories may have to be written down to market value due to the higher
costs assigned to LIFO layers in prior periods. In addition, the use of the LIFO
inventory method may result in increases or decreases to cost of sales in years
that inventory volumes decline as the result of charging cost of sales with LIFO
inventory costs generated in prior periods. An actual valuation of inventory
under the LIFO method is made at the end of each year based on the inventory
levels at that time. Accordingly, interim LIFO calculations are based on
management's estimates of expected year-end inventory levels and are subject to
the final year-end LIFO inventory valuation.

                                       55
--------------------------------------------------------------------------------
  Table of Content
At September 30, 2021, the LIFO value of inventory was equal to cost. Future
decreases in overall inventory values could result in an establishment of a
lower of cost or market inventory valuation reserve and additional charges to
cost of products sold.

Inventories consisting of process chemicals, materials and maintenance supplies
and RINs are stated at the lower of weighted-average cost or net realizable
value. Inventories of our Petro-Canada Lubricants and Sonneborn businesses are
stated at the lower of cost, using the FIFO method, or net realizable value.

Goodwill and Long-lived Assets: As of September 30, 2021, our goodwill balance
was $2.3 billion, with goodwill assigned to our Refining, Lubricants and
Specialty Products and HEP segments of $1,733.5 million, $247.0 million and
$312.9 million, respectively. Goodwill represents the excess of the cost of an
acquired entity over the fair value of the assets acquired and liabilities
assumed. Goodwill is not subject to amortization and is tested annually or more
frequently if an event occurs or circumstances change that would more likely
than not reduce the fair value of a reporting unit below its carrying amount.
Our goodwill impairment testing first entails either a quantitative assessment
or an optional qualitative assessment to determine whether it is more likely
than not that the fair value of a reporting unit is less than its carrying
amount. If we determine that based on the qualitative factors that it is more
likely than not that the carrying value of the reporting unit is greater than
its fair value, a quantitative test is performed in which we estimate the fair
value of the related reporting unit. If the carrying amount of a reporting unit
exceeds its fair value, the goodwill of that reporting unit is impaired, and we
measure goodwill impairment as the excess of the carrying amount of reporting
unit over the related fair value.

For purposes of long-lived asset impairment evaluation, we group our long-lived
assets as follows: (i) our refinery asset groups, which include certain HEP
logistics assets, (ii) our Lubricants and Specialty Products asset groups and
(iii) our HEP asset groups, which comprises HEP assets not included in our
refinery asset groups. These asset groups represent the lowest level for which
independent cash flows can be identified. Our long-lived assets are evaluated
for impairment by identifying whether indicators of impairment exist and if so,
assessing whether the long-lived assets are recoverable from estimated future
undiscounted cash flows. The actual amount of impairment loss measured, if any,
is equal to the amount by which the asset group's carrying value exceeds its
fair value.

We performed our annual goodwill impairment testing quantitatively as of July 1,
2021 and determined there was no impairment of goodwill attributable to our
reporting units. The estimated fair values of our reporting units were derived
using a combination of income and market approaches. The income approach
reflects expected future cash flows based on estimated forecasted production
levels, selling prices, gross margins, operating costs and capital expenditures.
Our market approaches include both the guideline public company and guideline
transaction methods. Both methods utilize pricing multiples derived from
historical market transactions of other like kind assets. The excess of the fair
values of the reporting units over their respective carrying values ranged from
12% to 162%. Increasing the discount rate by 1.0% or reducing the terminal cash
flow growth rate by 1.0% would not have changed the results of our annual
goodwill testing.

In performing our impairment test of goodwill, we developed cash flow forecasts
for each of our reporting units. Significant judgment is involved in performing
these fair value estimates since the results are based on forecasted financial
information. The cash flow forecasts include significant assumptions such as
planned utilization, end-user demand, selling prices, gross margins, operating
costs and capital expenditures. Another key assumption applied to these
forecasts to determine the fair value of a reporting unit is the discount rate.
The discount rate is intended to reflect the weighted average cost of capital
for a market participant and the risks associated with the realization of the
estimated future cash flows. Our fair value estimates are based on projected
cash flows, which we believe to be reasonable.

We continually monitor and evaluate various factors for potential indicators of
goodwill and long-lived asset impairment. A reasonable expectation exists that
further deterioration in our operating results or overall economic conditions
could result in an impairment of goodwill and / or long-lived asset impairments
at some point in the future. Future impairment charges could be material to our
results of operations and financial condition.

Contingencies


We are subject to proceedings, lawsuits and other claims related to
environmental, labor, product and other matters. We are required to assess the
likelihood of any adverse judgments or outcomes to these matters as well as
potential ranges of probable losses. A determination of the amount of reserves
required, if any, for these contingencies is made after careful analysis of each
individual issue. The required reserves may change in the future due to new
developments in each matter or changes in approach such as a change in
settlement strategy in dealing with these matters.

RISK MANAGEMENT

We use certain strategies to reduce some commodity price and operational risks.
We do not attempt to eliminate all market risk exposures when we believe that
the exposure relating to such risk would not be significant to our future
earnings, financial position, capital resources or liquidity or that the cost of
eliminating the exposure would outweigh the benefit.

Commodity Price Risk Management
Our primary market risk is commodity price risk. We are exposed to market risks
related to the volatility in crude oil and refined products, as well as
volatility in the price of natural gas used in our refining operations. We
periodically enter into derivative contracts in the form of commodity price
swaps, forward purchase and sales and futures contracts to mitigate price
exposure with respect to our inventory positions, natural gas purchases, sales
prices of refined products and crude oil costs.

Foreign Currency Risk Management
We are exposed to market risk related to the volatility in foreign currency
exchange rates. We periodically enter into derivative contracts in the form of
foreign exchange forward and foreign exchange swap contracts to mitigate the
exposure associated with fluctuations on intercompany notes with our foreign
subsidiaries that are not denominated in the U.S. dollar.

As of September 30, 2021, we have the following notional contract volumes related to all outstanding derivative instruments used to mitigate commodity price and foreign currency risk:

Interest Rate Risk Management
The market risk inherent in our fixed-rate debt is the potential change arising
from increases or decreases in interest rates as discussed below.

For the fixed rate HollyFrontier Senior Notes and HEP Senior Notes, changes in
interest rates will generally affect fair value of the debt, but not earnings or
cash flows. The outstanding principal, estimated fair value and estimated change
in fair value (assuming a hypothetical 10% change in the yield-to-maturity
rates) for this debt as of September 30, 2021 is presented below:

For the variable rate HEP Credit Agreement, changes in interest rates would
affect cash flows, but not the fair value. At September 30, 2021, outstanding
borrowings under the HEP Credit Agreement were $840.5 million. A hypothetical
10% change in interest rates applicable to the HEP Credit Agreement would not
materially affect cash flows.

Our operations are subject to hazards of petroleum processing operations,
including but not limited to fire, explosion, cyberattacks and weather-related
perils. We maintain various insurance coverages, including property damage,
business interruption and cyber insurance, subject to certain deductibles and
insurance policy terms and conditions. We are not fully insured against certain
risks because such risks are not fully insurable, coverage is unavailable, or
premium costs, in our judgment, do not justify such expenditures.

Financial information is reviewed on the counterparties in order to review and
monitor their financial stability and assess their ongoing ability to honor
their commitments under the derivative contracts. We have not experienced, nor
do we expect to experience, any difficulty in the counterparties honoring their
commitments.

We have a risk management oversight committee consisting of members from our
senior management. This committee oversees our risk enterprise program, monitors
our risk environment and provides direction for activities to mitigate
identified risks that may adversely affect the achievement of our goals.
