Phillips 66 PSX
Phillips 66's conglomerate structure buries a world-class refiner and >$40bn midstream inside a low-multiple wrapper; spinning midstream, fixing refining and Marathon-style buybacks unlock $200-$300+ per share.
Thesis
Phillips 66 operates the third-largest US refining system, a vertically integrated Permian/DJ NGL midstream, a 50% stake in CPChem and a cash-generative marketing business — yet trades at 6.6x EBITDA, a multiple consistent with assigning its refining segment just $1bn versus the $34bn it would command on a Valero-equivalent per-barrel basis. Shares have trailed VLO and MPC by 163% over a decade as management compounded the gap with dilutive midstream acquisitions, missed the $14bn 2025 mid-cycle EBITDA target by ~$5.7bn, and lagged Valero refining by ~$3.75/bbl in 2024. Elliott's 'Streamline 66' demands a midstream sale or spin, divestiture of CPChem and JET retail, ambitious refining margin targets, and new independent directors. Base case: ~$200/share (+65%); Marathon-path execution with buybacks: $300+/share (>150% upside).
SCQA
Phillips 66 is a ~$50bn-market-cap downstream conglomerate combining the third-largest US refining system, a vertically integrated Permian/DJ NGL midstream platform, a 50% CPChem petrochemical JV with Chevron, and a global marketing footprint.
Shares have trailed VLO and MPC by 163% over ten years; refining lags Valero by ~$3.75/bbl EBITDA, management missed its $14bn 2025 mid-cycle EBITDA target by $5.7bn, and dilutive midstream M&A has compounded the conglomerate discount.
Execute Streamline 66: sell or spin midstream, divest the CPChem JV stake and JET retail, commit to best-in-class refining EBITDA-per-barrel targets, add new independent directors, and review CEO Mark Lashier's leadership.
Sum-of-parts unlock plus operating fixes get to ~$200/share (+65%); Marathon-style asset sales and aggressive buybacks (retiring 60-90% of shares) could push the stock above $300 (>150% upside).
The three reasons
- 1
Conglomerate structure hides a Midstream worth >$40bn standalone; market gives refining ~$1bn of credit
- 2
Management missed 2025 $14bn mid-cycle EBITDA target by ~$5.7bn and recycled divestiture proceeds into dilutive M&A
- 3
Following Marathon's path of asset sales plus buybacks implies ~$200/share base case and $300+ upside vs $120 today
Primary demands
- Sell or spin the Midstream business
- Pursue sale of Phillips' 50% JV interest in CPChem
- Execute plan to sell the German and Austrian JET retail business
- Commit to ambitious refining targets matching VLO/MPC EBITDA per barrel
- Add new independent directors and review executive leadership
- Direct divestiture proceeds to share buybacks rather than midstream M&A

Notes
Campaign branded as 'Streamline 66' with Route-66 highway-shield visual motif carried throughout (cover, section dividers, footer logo). '10XEBITDA.com' watermark on every page indicates source. Builds on Elliott's prior Nov 2023 engagement letter — classified as follow_up since this is the expanded public thesis deck, not the first disclosure (no stake percentage disclosed in this document). Heavy use of Marathon Petroleum as explicit precedent: Elliott reuses its own 2019 'Remaking Marathon' deck (slide 41) as social proof for the upside math. Strong CEO-quote contradictions of Mark Lashier on Q4 2024 earnings calls paired with analyst skepticism from Wolfe Research, Goldman Sachs, TPH&Co, BofA. Three-pillar structure (Inefficient Conglomerate / Poor Operating Performance / Damaged Management Credibility) reinforced via red section tabs at top of every page. Striking hand-drawn fist-grip illustration on slide 23 visualizing the conglomerate trapping value. Closing ask is constructive shareholder engagement rather than proxy fight.
