Plains GP Holdings LP (PAGP) Income Statement

The 66.3% revenue growth in Q2 2026 is the most striking figure in the dataset, yet it follows a pattern of erratic swings—Q1 2026 grew only 3.8%, while 2025 quarters contracted between 9% and 17%. This suggests the top line is heavily influenced by the pass-through nature of the supply and logistics business, where revenue is grossed up by the value of crude traded. Investors should monitor whether this surge reflects higher throughput or simply wider price spreads, as the latter is less sustainable.

The gross margin trajectory shows a clear deterioration from the 8.2% peak in Q1 2025 to the current 4.6%, despite the revenue surge. This implies that the incremental revenue in Q2 2026 was generated at lower incremental margins, likely due to narrower regional price differentials and increased competition for uncommitted barrels. The structural gross margin of ~6% is well below peers like EPD (13.6%) and ET (21.8%), reflecting the heavy marketing component, but the recent decline suggests the fee-based mix may be shrinking.

While Q2 2026 operating income of $397M is the highest in the dataset, the operating margin of 2.2% is below the 4.4% achieved in Q1 2025, showing that revenue growth is not translating into proportional profit expansion. SG&A increased to $111M from $84M in Q2 2025, a 32% jump, which may reflect higher administrative costs or incentive compensation tied to the revenue spike. This suggests the company's high fixed-cost base is not being leveraged effectively, as variable costs and competitive pressures absorb the incremental revenue.

The cost structure is dominated by 'Purchases and Related Costs,' which are the direct costs of buying and selling crude oil and NGLs. This line item is the primary driver of the low gross margin, as it scales almost one-for-one with revenue. The $111M SG&A is relatively small, indicating a lean overhead structure, but the lack of R&D spending is typical for midstream. The key cost risk is not SG&A inflation but the volatility in purchase costs, which can compress margins when price spreads narrow, as seen in the declining gross margin trend.

The Q1 2025 period appears to be the inflection point where margins were at their most favorable, likely benefiting from wider WTI Midland-to-Houston spreads and strong utilization of uncommitted capacity. Since then, gross margin has declined to 4.6% in Q2 2026, a 44% drop from the peak, while operating margin has halved. This suggests that the Permian takeaway capacity additions and producer capital discipline have shifted the bargaining power away from midstream operators, a trend that may persist if volume growth plateaus.
