Business Overview: Par Pacific Holdings, Inc. (NYSE: PARR)

---

Executive Summary

Par Pacific Holdings, Inc. is a Houston-based, geographically diversified energy company that sources crude oil, refines it into transportation and industrial fuels, and distributes and markets those fuels through its own logistics and retail networks. The company took its current name in October 2015 after emerging from the bankruptcy of Delta Petroleum Corporation (operating in between as Par Petroleum Corporation), and today runs four refineries across the western United States: Kapolei, Hawaii; Billings, Montana; Tacoma, Washington; and Newcastle, Wyoming.

Par's defining strategic asset is its Kapolei refinery, which is the only operating oil refinery in the state of Hawaii following Chevron's 2016 exit from Hawaii refining. That single fact — an isolated island market with no in-state refining competitor — anchors much of the company's economics and its 2024-2026 earnings volatility, even as Par has diversified into mainland refining, logistics, and retail to reduce its historical dependence on Hawaii alone.

With roughly 219 Mbpd of combined refining capacity, company-owned pipelines, marine terminals and rail infrastructure, and retail fuel brands including Hele, 76, and nomnom, Par operates as a vertically integrated regional fuels company rather than a pure-play refiner.

1. Core Business Model & How They Work

Par Pacific creates value by moving crude oil through an integrated chain it controls at nearly every step in its core markets, capturing margin at the refining, logistics, and retail stages rather than relying on a single link in the value chain.

Crude is purchased entirely from third parties — Par owns no upstream crude production of its own (aside from a minority natural gas investment, see below) — and refined into gasoline, diesel, jet fuel, LPG, naphtha, marine fuel, and asphalt. Because each refinery sits in a distinct regional market (island Hawaii, the Pacific Northwest, and the northern Rockies/Plains), Par's logistics assets — a subsea pipeline and single-point mooring buoy in Hawaii, the wholly-owned Silvertip Pipeline and a 40% interest in the Yellowstone Pipeline in Montana, a jet-fuel pipeline to Joint Base Lewis-McChord in Washington, and pipelines serving Ellsworth Air Force Base and the Powder River Basin in Wyoming — are what let it actually get fuel from each refinery to its captive regional customers.

2. Business Segments

Par reports four segments: Refining, Retail, Logistics, and Corporate and Other. Refining is by far the largest contributor to gross margin, though its earnings are also by far the most volatile.

Refining (~67% of 2024 Adjusted Gross Margin)

Four refineries with a combined 219 Mbpd of crude throughput capacity: Kapolei, HI (94 Mbpd, Hawaii's only refinery), Billings, MT (63 Mbpd, acquired June 2023), Tacoma, WA (42 Mbpd), and Newcastle, WY (20 Mbpd). In 2024 the refineries together processed 186.7 Mbpd of crude and sold 199.9 Mbpd of refined product. Per-barrel adjusted gross margins vary widely by site — Wyoming ($13.73/bbl) and Montana ($11.37/bbl) were the strongest in 2024, Hawaii ($9.34/bbl) was mid-tier, and Washington ($3.25/bbl) was the thinnest.

Retail (~18% of 2024 Adjusted Gross Margin)

Company-operated and partner-operated fuel stations plus unattended commercial cardlocks across Hawaii, Washington, and Idaho, selling under the proprietary Hele brand, the exclusively-licensed 76 brand in Hawaii (license runs through October 31, 2031), the nomnom brand in Washington/Idaho, and Kauai Automated Fuels (KAF) cardlocks. Retail fuel volume reached 121.5 million gallons in 2024, up from 117.6 million in 2023.

Logistics (~15% of 2024 Adjusted Gross Margin)

Owned pipelines, marine terminals, storage, and rail infrastructure that connect each refinery to its market: an offshore single-point mooring buoy and undersea pipelines plus onshore storage in Hawaii; the wholly-owned Silvertip crude pipeline and a 40% stake in the Yellowstone refined-products pipeline in Montana (both acquired in the June 2023 Billings transaction); marine, rail, and a military jet-fuel pipeline in Washington; and crude and refined-product pipelines, including a dedicated line to Ellsworth Air Force Base, in Wyoming.

Corporate and Other

Primarily general and administrative costs, plus Par's 46% equity interest in Laramie Energy, LLC, a Colorado natural-gas producer (equity investment balance of $12.5 million at year-end 2024), and its 65% interest in Yellowstone Energy LP, a co-generation facility acquired alongside the Billings refinery.

4. Competitive Landscape

Par's competitive position differs sharply by geography and segment — it faces essentially no in-state refining competition in Hawaii, but ordinary multi-player competition in mainland retail markets.

Refining

Par's 10-K describes refining competitors generically as major integrated, national, and independent energy companies, many with greater financial resources — it names no specific refining competitors. In practice, Par competes with larger, better-capitalized refiners (companies like HF Sinclair, Marathon Petroleum, and Phillips 66) in its mainland markets, but in Hawaii specifically, Par's Kapolei plant is the only operating refinery in the state since Chevron exited Hawaii refining in 2016 (selling the asset to Island Energy Services, which Par later acquired in December 2018).

Retail — Hawaii

Named competitors include Shell, Texaco, Costco, Safeway, Sam's Club, the regional brand Aloha, and local independent retailers. Competition is on price, station appearance, location, service, and brand awareness.

Retail — Pacific Northwest

Named competitors include Chevron, Exxon, Conoco, Safeway, Costco, and regional brands Maverik, Holiday, and Fred Meyer, plus local independents.

5. Strategic Strengths & Risks

Strengths (The Moat)

• Sole refiner in Hawaii: With no competing in-state refinery, Par's Kapolei plant effectively has a captive share of Hawaii's refined-product demand, including virtually all of Hawaiian Airlines' jet fuel and roughly half of the military's in-state diesel needs — demand that cannot easily be met by mainland or Asian imports given shipping costs and Jones Act coastal-trade restrictions.
• Exclusive, long-dated brand license: The 76 retail brand license in Hawaii runs through October 2031, locking in a second retail channel alongside the proprietary Hele brand.
• Owned, hard-to-replicate logistics infrastructure: Subsea pipelines and a single-point mooring buoy in Hawaii, the wholly-owned Silvertip crude pipeline in Montana, and dedicated military-base pipelines in Washington and Wyoming would be difficult and capital-intensive for a new entrant to duplicate.
• Geographic and segment diversification: The 2023 Billings, Montana acquisition and the Wyoming and Washington refineries reduce Par's historical dependence on Hawaii alone, spreading commodity-cycle risk across four distinct regional markets.

Risks

• Refining-margin cyclicality: Par swung from $728.6 million of net income in 2023 to a net loss of $33.3 million in 2024 purely on crack-spread compression — the business is directly exposed to volatile, largely non-contracted refining margins.
• Electrification/fuel-switching threat in Hawaii: A proposed 500-megawatt LNG power plant on Oahu, backed by the state administration, could reduce long-term oil demand for Hawaii power generation, a risk Par has flagged to shareholders.
• Jones Act dependency and political scrutiny: Par's cost structure and competitive insulation both depend partly on the Jones Act's coastal-shipping restrictions, which lawmakers such as Rep. Ed Case have criticized as raising costs for Hawaii consumers — a policy change could cut both ways for Par.
• Customer concentration: A single refining customer accounted for 12% of consolidated 2024 revenue (down from 17% in 2022).
• Rising leverage: Total debt grew from $650.9 million at year-end 2023 to $1.11 billion at year-end 2024, largely reflecting financing for the Billings acquisition.
• Thin-margin assets within the portfolio: The Washington refinery generated only $3.25 of adjusted gross margin per barrel in 2024, the weakest of Par's four plants, showing real commodity exposure outside Hawaii.
• Labor relations: About 23% of employees at the Hawaii, Washington, and Montana refineries are represented by the United Steelworkers under an agreement effective through January 31, 2026, creating near-term renewal risk.

7. Summary Conclusion

Par Pacific's business is best understood as one structurally advantaged, geographically-isolated franchise — its sole-refiner position in Hawaii — wrapped around a more ordinary, commodity-exposed mainland refining and retail business in Montana, Washington, and Wyoming. The Hawaii franchise, reinforced by an exclusive long-dated 76 brand license and logistics assets that would be very expensive to replicate, gave Par outsized profits when global refining margins spiked in 2025-2026, but the same concentration makes its earnings highly sensitive to crack-spread cycles, as shown starkly by the swing from a $728.6 million profit in 2023 to a net loss in 2024.

Looking forward, Par's durability depends on whether its Hawaii position holds against longer-term electrification and LNG-switching pressure in the state's power sector, while its mainland refineries — particularly the thinner-margin Washington plant — need to keep contributing enough to diversify the company away from Hawaii-driven volatility without taking on excessive leverage from further acquisitions like the 2023 Billings deal.
