Asked about MPLX's asset position (Mount Airy, LOOP, NGL dock) and commercial activity in light of increased demand for US hydrocarbon exports due to Middle East disruptions.

Management noted increased utilization at Mount Airy and LOOP due to market dynamics and Venezuelan crude imports. They reiterated that the Gulf Coast NGL export dock and fractionator complex are on track for 2028/2029 in-service, with high confidence in full utilization. “As we look at what's going on in the market dynamics right now and we look at our asset base, Mount Airy is a great example. We're located strategically right next to Garyville and based on some of the market things going on, I think MPC and others will continue to lean into that. So we anticipate that asset utilization will be increasing some.”

Inquired about the confidence in growing distributions by 12.5% for 2026 and 2027 while maintaining a 1.3x coverage threshold, implying significant cash flow growth.

Management affirmed their commitment to the 12.5% distribution growth for both years, stating that maintaining coverage at or above 1.3x is a key financial metric and that expected cash flow growth supports this. “When we think about our 12.5% distribution growth both for this year 2026 and 2027, we've set financial metrics for that and one of which is, as you stated, that our coverage doesn't fall below 1.3. So that is our commitment.”

Asked why buybacks decreased to $50 million in Q1 from a programmatic $100 million per quarter, and if the company intends to retain more cash.

Management stated there was no change in their capital allocation strategy. Distributions remain the primary tool, with buybacks being a flexible method. They believe MPLX units trade at a discount and the current buyback level reflects this belief. “no change to our capital allocation methodology or strategy. Distributions will continue to be that primary tool to return capital to unitholders with the unit repurchases really being that more flexible method of returning capital.”

Executive summary

MPLX Q1 FY26 — Strong EBITDA and Project Execution Drive Confidence in Future Growth

MPLX delivered robust Q1 FY26 adjusted EBITDA and significant unitholder returns, underpinned by strong project execution and strategic investments in natural gas and NGL infrastructure. The company is confident in its back-half weighted growth trajectory for 2026, driven by key projects coming online, and remains committed to its mid-single-digit growth target and distribution increase framework.

Highlights

Adjusted EBITDA exceeded $1.7 billion in Q1 FY26, enabling over $1.1 billion in unitholder returns.
Secretary at ONE processing plant (200 MMcf/d capacity) entered service in April, with Harmon Creek III and Titan complex expansion on track for later in 2026.
Gathering volumes increased 10% year-over-year (excluding divestitures) due to production growth in the Utica and Permian basins.
Processing volumes increased 2% year-over-year, driven by Marcellus and Permian production.
Marcellus processing utilization was 94% for the quarter, demonstrating strong demand for new capacity.

Concerns

Segment adjusted EBITDA for Gathering & Processing decreased $42 million year-over-year, primarily due to a $45 million impact from 2025 asset divestitures and lower NGL prices.
Crude pipeline throughputs decreased 4% year-over-year due to Marathon's refining turnaround and maintenance activities.
Terminal volumes decreased 4% year-over-year due to less favorable market dynamics and refining industry turnaround activity.
A Winter Storm in January resulted in a roughly $13 million headwind to Q1 results.
A negative mark-to-market of $56 million was recognized from NGL price hedging, though expected to be offset by physical gains.

Segment performance

Segment	Revenue	YoY	QoQ	Margin
Crude Oil & Products Logistics Segment adjusted EBITDA increased primarily due to higher rates across business units, partially offset by lower crude pipeline throughputs and terminal volumes. Lower throughputs were driven by Marathon's refining turnaround and maintenance activities in the Midwest and Gulf Coast regions, and less favorable market dynamics. Crude pipeline throughputs: decreased 4% YoYTerminal volumes: decreased 4% YoY	—	—	—	increased $14 million
Gathering & Processing Segment adjusted EBITDA decreased primarily due to a $37 million one-time benefit in Q1 2025, a $45 million impact from 2025 noncore asset divestitures, lower natural gas liquids prices, and higher operating expenses. These factors offset growth from equity affiliates and increased volumes inclusive of acquisitions. Gathering volume growth was driven by production in the Utica and Permian, while processing volume growth was from Marcellus and Permian. Fractionation volumes decreased due to lower ethane recovery in the Marcellus from elevated regional gas prices. Gathering volumes (excluding Rockies divestiture): up 10% YoYProcessing volumes: increased 2% YoYMarcellus processing utilization: 94%Total fractionation volumes: decreased 3% YoY	—	—	—	decreased $42 million

Q&A highlights

Asked for more detail on how MPLX expects to achieve its higher EBITDA growth target for 2026 (stronger than 2025) given a flattish Q1, and how the ramp-up of projects will contribute.

Management confirmed the 2026 growth would be stronger than 2025, but back-half weighted. They cited Secretary at ONE (now in service), Harmon Creek III (Q3 in-service), and Titan complex expansion (Q4 completion) as key drivers. They also mentioned confidence in maintaining the 12.5% distribution increase for 2026 and 2027.

“The back half of the year, we expect to be stronger clearly than the first half of the year. And we see good line of sight to that, which also continues to give us confidence, frankly, in our 12.5% distribution increase.”

Detailed narrative

Strategic Investments in Natural Gas & NGLs

MPLX is heavily investing in natural gas and NGL infrastructure, with 90% of its $2.4 billion organic growth capital plan directed towards these opportunities. Key projects like Secretary at ONE (200 MMcf/d processing), Secretary at TWO (300 MMcf/d processing), Harmon Creek III (300 MMcf/d processing), and the Titan complex expansion (to over 400 MMcf/d treating capacity) are central to this strategy.

These investments aim to strengthen the company's position in the Delaware Basin and Marcellus, supporting activity in low-cost sour gas windows and enhancing the competitiveness of its value chain.

Integrated NGL Value Chain

The company is advancing construction across its Gulf Coast fractionation and export facilities, which are on time and on budget. This fully integrated NGL value chain, including the BANGL pipeline expansion to 300,000 bbl/d, is expected to provide high confidence in future volumes, utilization, and durable cash flow, capitalizing on increasing global demand for secure U.S. energy exports.

Permian Basin Expansion

In the Delaware Basin, the Titan facility successfully treated over 150 MMcf/d of committed producer sour gas in Q1, with March seeing the strongest performance. A third acid gas injection well is expected to be completed in Q3. The Titan complex expansion is on schedule to reach over 400 MMcf/d treating capacity by Q4.

The Secretary at ONE processing plant entered service in April, and Secretary at TWO (300 MMcf/d) is planned for H2 2028, bringing total basin processing capacity to approximately 1.7 Bcf/d.

Northeast and Long-Haul Pipeline Growth

Construction of Harmon Creek III in the Marcellus is on track for a Q3 in-service date, increasing total Northeast processing capacity to 8.1 Bcf/d. The Blackcomb natural gas pipeline is progressing for a Q4 in-service, and the BANGL pipeline expansion is also expected online in Q4.

These projects, along with others like Iger (H2 2028), underscore the demand for firm takeaway capacity and the long-term durability of MPLX's natural gas system, providing flexibility to markets like Agua Dulce and Katy.

Capital Allocation Strategy

MPLX maintains a disciplined capital allocation strategy, prioritizing distributions to unitholders and utilizing unit repurchases as a flexible method for returning capital. The company is committed to its 12.5% distribution growth for 2026 and 2027, ensuring coverage remains at or above 1.3x, supported by expected cash flow growth from its project pipeline.

Management believes MPLX units trade at a discount, which is reflected in its current buyback program.
