Reported net income attributable to HEP of $68.5 million or $0.54 per unit
Announced quarterly distribution of $0.35 per unit
Reported EBITDA of $88.6 million and Adjusted EBITDA of $115.7 million

Holly Energy Partners, L.P. ("HEP" or the "Partnership") (NYSE:HEP) today reported financial results for the fourth quarter of 2022. Net income attributable to HEP for the fourth quarter was $68.5 million ($0.54 per basic and diluted limited partner unit) compared to $45.6 million ($0.43 per basic and diluted limited partner unit) for the fourth quarter of 2021.

Distributable cash flow was $85.8 million for the fourth quarter of 2022, an increase of $22.7 million, or 36.1%, compared to the fourth quarter of 2021. HEP declared a quarterly cash distribution of $0.35 on January 20, 2023.

The increase in net income attributable to HEP was mainly due to net income from Sinclair Transportation Company LLC ("Sinclair Transportation"), which was acquired on March 14, 2022, and pipeline revenues, partially offset by higher interest expense.

Commenting on our 2022 fourth quarter results, Michael Jennings, Chief Executive Officer and President, stated, "HEP delivered another excellent quarter, supported by record volumes across our integrated system. We continue to generate stable earnings and cash flow, and expect to achieve our leverage target of 3.5 times in mid-2023. Once that is reached, we look forward to evaluating incremental cash return to unitholders consistent with our previously announced capital allocation strategy."

Fourth Quarter 2022 Revenue Highlights

Revenues for the fourth quarter of 2022 were $142.5 million, an increase of $24.0 million compared to the fourth quarter of 2021. The increase was mainly due to revenues on our recently acquired Sinclair Transportation assets, higher volumes on our crude and product pipelines, and rate increases that went into effect on July 1, 2022.

Revenues from our refined product pipelines were $30.4 million, an increase of $7.7 million, on shipments averaging 184.4 thousand barrels per day ("mbpd") compared to 135.2 mbpd for the fourth quarter of 2021. The revenue and volume increases were mainly due to volumes on our recently acquired Sinclair Transportation product pipelines, higher volumes on our Navajo and Woods Cross product pipelines, and rate increases that went into effect on July 1, 2022. Revenues did not increase in proportion to volumes due to our recognition of a significant portion of the Sinclair Transportation refined product pipeline tariffs as interest income under sales-type lease accounting.

Revenues from our intermediate pipelines were $8.4 million, an increase of $0.8 million on shipments averaging 137.4 mbpd compared to 105.5 mbpd for the fourth quarter of 2021. The increase in volumes was mainly due to higher throughputs on our intermediate pipelines servicing HF Sinclair Corporation's ("HF Sinclair") Navajo refinery and the recently acquired Sinclair Transportation intermediate pipelines, and revenues increased mainly due to rate increases that went into effect on July 1, 2022 as well as revenues on the recently acquired Sinclair Transportation intermediate pipelines.

Revenues from our crude pipelines were $36.5 million, an increase of $5.8 million, on shipments averaging 622.2 mbpd compared to 455.0 mbpd for the fourth quarter of 2021. The increase in volumes and revenues was mainly attributable to our recently acquired Sinclair Transportation crude pipelines, our Cushing Connect pipeline, higher volumes on our crude pipeline systems in New Mexico, Texas, Wyoming and Utah as well as rate increases that went into effect on July 1, 2022. Revenues did not increase in proportion to volumes due to our recognition of most of the Cushing Connect pipeline tariffs and a significant portion of the Sinclair Transportation crude pipeline tariffs as interest income under sales-type lease accounting.

Revenues from terminal, tankage and loading rack fees were $41.8 million, an increase of $7.9 million compared to the fourth quarter of 2021. Refined products and crude oil terminalled in the facilities averaged 666.6 mbpd compared to 460.4 mbpd for the fourth quarter of 2021. Volumes increased mainly due to volumes on our recently acquired Sinclair Transportation assets and higher throughputs at HF Sinclair's Tulsa refinery. Revenues increased mainly due to revenues on our recently acquired Sinclair Transportation assets, higher butane blending revenues, higher revenues on our Tulsa assets, and rate increases that went into effect on July 1, 2022.

Revenues from refinery processing units were $25.5 million, an increase of $1.8 million compared to the fourth quarter of 2021, and throughputs averaged 71.2 mbpd compared to 68.8 mbpd for the fourth quarter of 2021. The increase in volumes was mainly due to increased throughput for our Woods Cross processing units. Revenues increased mainly due to higher throughput at our Woods Cross refinery processing units as well as rate increases that went into effect on July 1, 2022.

Year Ended December 31, 2022 Revenue Highlights

Revenues for the year ended December 31, 2022, were $547.5 million, an increase of $53.0 million compared to the year ended December 31, 2021. The increase was mainly attributable to revenues on our recently acquired Sinclair Transportation assets, increased revenues from our UNEV assets, higher volumes on our crude pipelines in New Mexico, Texas, Wyoming and Utah as well as rate increases that went into effect on July 1, 2022, partially offset by lower revenues on our Cheyenne assets as a result of the conversion of HF Sinclair's Cheyenne refinery to renewable diesel production. The year ended December 31, 2021 included the recognition of the $10 million termination fee related to the termination of HF Sinclair's minimum volume commitment on our Cheyenne assets.

Revenues from our refined product pipelines were $113.2 million, an increase of $5.8 million, on shipments averaging 181.3 mbpd compared to 158.1 mbpd for the year ended December 31, 2021. The volume and revenue increases were mainly due to higher volumes on our recently acquired Sinclair Transportation assets and higher volumes on our UNEV pipeline. We recognized a significant portion of the Sinclair Transportation refined product pipeline tariffs as interest income under sales-type lease accounting.

Revenues from our intermediate pipelines were $32.2 million, an increase of $2.1 million compared to the year ended December 31, 2021. Shipments averaged 129.3 mbpd compared to 125.2 mbpd for the year ended December 31, 2021. The increase in volumes was mainly due to higher throughputs on our intermediate pipelines servicing HF Sinclair's Tulsa and Navajo refineries and the recently acquired Sinclair Transportation intermediate pipelines, and the increase in revenues was mainly due to the recently acquired Sinclair Transportation intermediate pipelines.

Revenues from our crude pipelines were $140.0 million, an increase of $14.4 million compared to the year ended December 31, 2021. Shipments averaged 601.3 mbpd compared to 408.6 mbpd for the year ended December 31, 2021. The increase in volumes was mainly attributable to our Cushing Connect pipeline, which went into service in September 2021, volumes on our recently acquired Sinclair Transportation crude pipelines and higher volumes on our crude pipeline systems in New Mexico, Texas, Wyoming and Utah. The increase in revenues was mainly due to our recently acquired Sinclair Transportation crude pipelines and higher volumes on our crude pipelines in New Mexico, Texas, Wyoming and Utah. Revenues did not increase in proportion to volumes due to our recognition of most of the Cushing Connect pipeline tariffs and a significant portion of the Sinclair Transportation crude pipeline tariffs as interest income under sales-type lease accounting.

Revenues from terminal, tankage and loading rack fees were $167.8 million, an increase of $25.5 million compared to the year ended December 31, 2021. Refined products and crude oil terminalled in the facilities averaged 598.2 mbpd compared to 442.9 mbpd for the year ended December 31, 2021. Volumes increased mainly due to volumes on our recently acquired Sinclair Transportation assets and higher throughputs at HF Sinclair's Tulsa refinery. Revenues increased mainly due to revenues on our recently acquired Sinclair Transportation assets, higher butane blending revenues and higher revenues on our Tulsa assets. In addition, the year ended December 31, 2021 included the recognition of the $10 million termination fee related to the termination of HF Sinclair's minimum volume commitment on our Cheyenne assets as a result of the conversion of the HF Sinclair Cheyenne refinery to renewable diesel production.

Revenues from refinery processing units were $94.2 million, an increase of $5.1 million compared to the year ended December 31, 2021. Throughputs averaged 70.2 mbpd compared to 69.6 mbpd for the year ended December 31, 2021. The increase in volumes was mainly due to increased throughput for our Woods Cross processing units. Revenues increased mainly due to higher recovery of natural gas costs as well as higher throughputs.

Operating Costs and Expenses Highlights

Operating costs and expenses were $82.6 million and $326.7 million for the three months and year ended December 31, 2022, respectively, representing an increase of $13.4 million and $38.7 million from the three months and year ended December 31, 2021, respectively. The increase for the three months ended December 31, 2022 was mainly due to operating costs and expenses associated with our recently acquired Sinclair Transportation assets, higher employee costs and higher utility costs, partially offset by lower maintenance and property tax costs. The increase for the year ended December 31, 2022 was mainly due to operating costs and expenses associated with our recently acquired Sinclair Transportation assets and higher employee costs, utility costs, natural gas costs, and maintenance costs, partially offset by lower general services costs and a goodwill impairment charge recognized in the year ended December 31, 2021.

Interest Expense and Interest Income Highlights

Interest expense was $25.6 million and $82.6 million for the three months and year ended December 31, 2022, respectively, representing increases of $12.4 million and $28.7 million over the same periods of 2021. The increases were mainly due to our April 2022 issuance of $400 million aggregate principal amount of 6.375% senior unsecured notes maturing in April 2027, the proceeds of which were used to partially repay outstanding borrowings under our senior secured credit facility following the funding of the cash portion of the Sinclair Transportation acquisition. In addition, market interest rates increased on our senior secured revolving credit facility.

Interest income for the three months and year ended December 31, 2022, totaled $30.2 million and $91.4 million, representing increases of $20.3 million and $61.5 million compared to the three months and year ended December 31, 2021. The increases were mainly due to higher sales-type lease interest income from our recently acquired Sinclair Transportation pipelines and terminals and our Cushing Connect pipeline, which was placed into service at the end of the third quarter of 2021.

Equity in Earnings of Equity Method Investments Highlights

Equity in earnings of equity method investments was a gain of $7.0 million for the three months ended December 31, 2022 and a loss of $0.3 million for the year ended December 31, 2022, representing an increase of $3.4 million and a decrease of $12.7 million compared to the three months and year ended December 31, 2021. The increase for the three months ended December 31, 2022 was mainly due to the addition of equity in earnings from Pioneer Investments Corp., which was acquired as part of our Sinclair Transportation acquisition.

The decrease for the year ended December 31, 2022 was mainly due to lower earnings from our equity method investment in Osage Pipe Line Company, LLC ("Osage") due to HEP's 50% share of incurred and estimated environmental remediation and recovery expenses, net of insurance proceeds received to date, of $17.6 million associated with a release of crude oil that occurred in the third quarter of 2022. Any additional insurance recoveries will be recorded as they are received. If our insurance policy pays out in full, our share of the remaining insurance coverage is expected to be $9.5 million. The pipeline resumed operations in the third quarter of 2022 and remediation efforts are underway. The decrease in equity in earnings from Osage was partially offset by the addition of equity in earnings from Pioneer Investments Corp., which was acquired as part of our Sinclair Transportation acquisition.

(1)		Earnings before interest, taxes, depreciation and amortization ("EBITDA") is calculated as net income attributable to Holly Energy Partners plus or minus (i) interest expense, (ii) interest income, (iii) state income tax (benefit) expense and (iv) depreciation and amortization. Adjusted EBITDA is calculated as EBITDA plus or minus (i) gain on sales-type leases, (ii) gain on significant asset sales, (iii) goodwill impairment, (iv) our share of Osage environmental remediation costs, net of insurance recoveries, included in equity in earnings of equity method investments, (v) acquisition integration and regulatory costs, (vi) tariffs and fees not included in revenues due to impacts from lease accounting for certain tariffs and fees and (vii) pipeline lease payments not included in operating costs and expenses. Portions of our minimum guaranteed tariffs for assets subject to sales-type lease accounting are recorded as interest income with the remaining amounts recorded as a reduction in net investment in leases. Similarly, certain pipeline lease payments were previously recorded as operating costs and expenses, but the underlying lease was reclassified from an operating lease to a financing lease, and these payments are now recorded as interest expense and reductions in the lease liability. EBITDA and Adjusted EBITDA are not calculations based upon generally accepted accounting principles ("GAAP"). However, the amounts included in the EBITDA and Adjusted EBITDA calculations are derived from amounts included in our consolidated financial statements. EBITDA and Adjusted EBITDA should not be considered as alternatives to net income attributable to Holly Energy Partners or operating income, as indications of our operating performance or as alternatives to operating cash flow as a measure of liquidity. EBITDA and Adjusted EBITDA are not necessarily comparable to similarly titled measures of other companies. EBITDA and Adjusted EBITDA are presented here because they are widely used financial indicators used by investors and analysts to measure performance. EBITDA and Adjusted EBITDA are also used by our management for internal analysis and as a basis for compliance with financial covenants.

		Set forth below is our calculation of EBITDA and Adjusted EBITDA.

(2)		Distributable cash flow is not a calculation based upon GAAP. However, the amounts included in the calculation are derived from amounts presented in our consolidated financial statements, with the general exception of maintenance capital expenditures. Distributable cash flow should not be considered in isolation or as an alternative to net income attributable to Holly Energy Partners or operating income, as an indication of our operating performance, or as an alternative to operating cash flow as a measure of liquidity. Distributable cash flow is not necessarily comparable to similarly titled measures of other companies. Distributable cash flow is presented here because it is a widely accepted financial indicator used by investors to compare partnership performance. It is also used by management for internal analysis and our performance units. We believe that this measure provides investors an enhanced perspective of the operating performance of our assets and the cash our business is generating.

		Set forth below is our calculation of distributable cash flow.
