Phillips 66 PSX
Phillips 66's refining + midstream conglomerate has underperformed pure-play peers by up to 188% over a decade; separating the businesses would eliminate the structural discount.
Thesis
Elliott's Streamline66 campaign argues that Phillips 66 is a mis-designed conglomerate whose refining and midstream businesses have contrasting risk/return propositions and should not be combined. The evidence is a decade of deep underperformance: cumulative total returns lag Valero by 138% and Marathon by 188%, with 1-, 3-, 5- and 10-year gaps of -9%, -33%, -97% and -163%. Since Elliott's November 2023 letter, PSX has tracked refining peers on the way down while midstream peers (Enterprise, MPLX, ONEOK, Targa) have rallied — showing the market assigns no credit for PSX's midstream assets. The ask is for the board to consider all options, implicitly including a spin or sale of midstream, to close the structural valuation gap.
SCQA
Phillips 66 is a large integrated downstream energy company operating a refining business alongside a substantial midstream segment, trading publicly under the PSX ticker.
The two businesses have contrasting risk/return profiles; PSX shows weak capital returns versus pure refiners and poor growth versus midstream peers, and trades like a refiner with no credit for midstream.
Management and the board should take bold action and consider all options — including separating refining from midstream — to remedy the inefficient conglomerate structure.
Closing the gap with Valero (+138%) and Marathon (+188%) implies a very large re-rating; a midstream separation would surface value the market currently ignores.
The three reasons
- 1
Phillips 66 underperformed Valero by 138% and Marathon by 188% over 10 years
- 2
Refining and midstream businesses have contrasting risk/return profiles and don't fit together
- 3
PSX trades like a refiner with no credit for its midstream business
Primary demands
- Consider all strategic options at Phillips 66 to unlock value
- Address inefficient conglomerate structure combining refining and midstream
- Narrow the performance gap with refining peers (Valero, Marathon)

Notes
SEC exhibit (ex99.1 to DFAN14A-style proxy solicitation filing) reproducing two Streamline66 social media posts — Streamline66 is Elliott's branded campaign vehicle against Phillips 66. Content is two X/Twitter screenshots, each featuring a clean branded infographic (red/black Streamline66 palette). First post: peer-gap bar chart vs Valero/Marathon across 1/3/5/10Y. Second post: line chart showing PSX tracking refining peers downward while midstream peers rally since Elliott's Nov 29, 2023 letter. Campaign is part of a multi-year proxy push; these posts function as short, sharable proof-points rather than a full thesis deck.
