Phillips 66’s NGL Integrated Value Chain
Expansion and Refining Optimization Action
Plan
Strategic Execution Framework • 2026–2028
I
STRATEGIC FOUNDATION
Phillips 66’s latest strategic execution is centered on building an integrated NGL value chain from the Permian wellhead through processing,
pipelines, fractionation and market access, while selectively improving the economics of its refining portfolio. The 2026 capital program
provides the clearest current foundation: approximately
$2.4 billion
of total capital, including approximately
$1.3 billion of growth capital
.
The growth program is increasingly concentrated in assets that connect production to premium markets. Iron Mesa and the newly sanctioned
Zeus gas-processing projects expand Permian capability, while the Coastal Bend system links NGL supply with Gulf Coast fractionation and
market outlets. A third Coastal Bend fractionator is planned to add another 100,000 barrels per day of fractionation capacity.
The downstream component is deliberately selective. Phillips 66 is investing in the Humber gasoline-quality improvement project and more
than 100 low-capital, high-return refining initiatives while continuing to optimize its global refinery footprint. The integration of selected Lindsey
assets with Humber demonstrates the preference for strengthening advantaged infrastructure rather than simply maintaining standalone
capacity.
Market access is another strategic layer. In August 2026, Phillips 66, Kinder Morgan and HF Sinclair reached final investment decision on the
Western Gateway Pipeline, designed to strengthen refined-products connectivity between Midcontinent/Gulf Coast supply and western
markets.
DIGITAL & OPERATING OPTIMIZATION
Phillips 66 is also applying digital tools such as Advanced Process Control across the Coastal Bend system to improve throughput, stability
and operating flexibility. Digital execution should therefore be measured through asset performance rather than through unsupported
enterprise-wide AI claims.
SUSTAINABILITY FOUNDATION
Environmental performance remains integrated into operations through greenhouse-gas, methane, water, energy-efficiency, renewable-fuels
and safety programs. These priorities complement the core economic strategy; they should not be represented as replacing Phillips 66’s
current emphasis on returns and portfolio optimization.

7. Risks, Dependencies & Mitigation
Commodity & margin cycles
Refining and NGL economics can change rapidly with commodity prices, crack spreads and regional differentials.
Stress-test project economics; stage investment; prioritize advantaged infrastruct
Permitting / construction
Large processing, pipeline and fractionation projects can face permitting, contractor, schedule or cost risks.
Gate approvals; maintain contingency plans; monitor critical-path milestones.
Network imbalance
New processing or fractionation capacity can underperform if gathering and downstream market access are not synchronized.
Coordinate wellhead, pipeline, fractionation and commercial capacity before startup.
Refinery reliability
Turnarounds, equipment failures and process-safety events can reduce throughput.
Integrated reliability planning, inspection, maintenance and restart controls.
Portfolio transition
Asset closures or integration can create one-time costs and operational complexity.
Use transition plans, workforce readiness, infrastructure mapping and benefits tracking.
Environmental / regulatory
Changing emissions, water or fuel standards may affect project economics and operating requirements.
Embed environmental review in project design and maintain compliance monitoring.
Capital competition
Growth investment competes with sustaining capital and shareholder returns.
Use transparent project-ranking gates and quarterly portfolio reviews.

SOURCE BASIS
Primary sources: Phillips 66 Investor Relations — 2026 Capital Budget; Phillips 66 Q2 2026 Results; Phillips 66 newsroom releases on Coastal Bend, Iron Mesa, Zeus and

FINAL EXECUTIVE TAKEAWAY
Phillips 66’s latest real-world strategy is best represented as an
integrated value-chain optimization program
. The company is expanding
advantaged NGL infrastructure from the Permian to Gulf Coast markets, improving fractionation and logistics connectivity, selectively
upgrading refining assets, integrating strategically useful infrastructure, and strengthening western-market supply optionality. The winning
execution model is therefore not maximum capacity at any cost; it is
connected capacity + higher-value yields + market access +
disciplined capital allocation
.
