[Trailblazer Pipeline (TPC)] [OPERATIONAL ALERT] THIRD PARTY OPERATIONAL ISSUE - BERTRAND COMPRESSOR STATION - UPDATE #14

SEV 5/5
Compressor Issue 0.808 Bcf/d Until Further Notice

Trailblazer Pipeline Segment 20 remains restricted to 0.808 Bcf/d effective Gas Day June 2, 2026, until further notice due to an ongoing third-party operational issue at Bertrand Compressor Station -- now in its 14th update. Primary firm, secondary firm, and ITS/AOR quantities are all explicitly at risk of not being scheduled. No restoration timeline has been provided.

Bertrand CS constraint caps Trailblazer at 0.808 Bcf/d with firm service at risk; because REX leases capacity at the same Bertrand CS facility, these two Rockies eastbound pipes are simultaneously constrained -- expect continued bearish pressure on Rockies basin (CIG/Cheyenne Hub) as eastbound takeaway remains impaired with no reroute.
Reroute: None: Trailblazer and REX share the Bertrand Compressor Station -- the same third-party facility constraining Trailblazer simultaneously affects REX Zone 1, eliminating the primary reroute alternative for Rockies eastbound volumes.

[OPERATIONAL ALERT] BERTRAND COMPRESSOR STATION OPERATIONAL ISSUE - UPDATE #14

SEV 5/5
Compressor Issue 1.115 Bcf/d Until Further Notice

Rockies Express Bertrand Compressor Station operational issue (Update #14) restricts Segment 250 West-to-East capacity to 1.115 Bcf/d effective Gas Day June 2, 2026, until further notice. Primary firm, secondary firm, and interruptible service are all at risk of not being scheduled. No restoration timeline has been provided.

REX Segment 250 constrained to 1.115 Bcf/d W-to-E with primary and secondary firm at risk; Trailblazer shares Bertrand CS and is simultaneously affected -- expect bullish pressure at Midcontinent and Chicago Citygate as Rockies takeaway is curtailed with zero independent reroute.
Reroute: None: REX and Trailblazer share Bertrand Compressor Station -- both are simultaneously constrained by the same facility, leaving no independent reroute for Rockies eastbound volumes. CIG provides limited alternative egress but cannot absorb full displaced volumes.

Transwestern Pipeline

[Transwestern Pipeline] [Capacity Constraint] GUYMAN POINT GROUP

SEV 4/5
Force Majeure 1 Days

Transwestern Pipeline has declared a force majeure capacity constraint at the Guyman Point Group, effective June 8, 2026 at 9:00 AM through June 9, 2026 at 8:59 AM -- a roughly 24-hour outage window. No specific volume figure is provided in the notice. Guyman is a major receipt/delivery group on TW serving the Oklahoma/Texas Panhandle corridor, with westbound flow implications toward SoCal border and Arizona delivery points.

TW force majeure at Guyman Point Group reduces westbound takeaway capacity for one day; expect bearish pressure at Waha and San Juan Basin receipt points with bullish pressure at SoCal Border and Arizona delivery points -- EPNG is the primary reroute alternative but may lack sufficient spare capacity to fully absorb curtailed TW volumes.
Reroute: Moderate: EPNG is the primary competing pipeline serving SoCal border and Arizona delivery points from the same supply basin; however, if EPNG is also running near capacity, reroute relief will be limited and SoCal Border basis tightening could be material for the duration.

[Transwestern Pipeline] [Capacity Constraint] GUYMAN POINT GROUP

SEV 4/5
Force Majeure 1 Days

Transwestern Pipeline has declared a Force Majeure capacity constraint at the Guyman Point Group, effective June 7, 2026 at 9:00 AM through June 8, 2026 at 8:59 AM -- a roughly 24-hour event. No specific capacity volume is stated in the notice. Guyman is a key receipt/delivery group on Transwestern serving the Oklahoma/Texas Panhandle corridor that feeds westbound flows toward SoCal Border and Arizona delivery points.

TW force majeure at Guyman Point Group removes unquantified westbound takeaway capacity for approximately 1 day; expect bullish pressure at SoCal Border and Arizona delivery points, with mild bearish pressure at upstream Panhandle/Anadarko Basin receipt points -- no volume disclosed so magnitude is uncertain but FM status warrants severity 4.
Reroute: Moderate: EPNG (El Paso Natural Gas) is the primary competing pipeline serving SoCal Border and Arizona markets from the east; however, if EPNG is also capacity-constrained, California supply relief would be severely limited. Guyman Point Group serves the Oklahoma/Texas Panhandle corridor, where EPNG may provide partial alternative westbound capacity.

[Transwestern Pipeline] [Capacity Constraint] GUYMAN POINT GROUP

SEV 4/5
Force Majeure 1 Days

Transwestern Pipeline has declared force majeure at the Guyman Point Group, effective June 7, 2026 at 9:00 AM through June 8, 2026 at 8:59 AM -- a one-day event. No specific capacity volume is stated in the notice. Guyman Point Group is a receipt cluster on Transwestern that pulls Permian and San Juan Basin production westbound toward SoCal Border and Arizona delivery markets.

TW force majeure at Guyman Point Group tightens westbound Permian/San Juan takeaway; expect bearish pressure at Waha as basin gas backs up and bullish pressure at SoCal Border and Arizona delivery points -- no volume stated but reroute depends on available EPNG spare capacity.
Reroute: Moderate: El Paso Natural Gas (EPNG) is the primary competing pipeline serving SoCal Border and Arizona from the Permian Basin; however, if EPNG is simultaneously constrained or running near capacity, reroute options are effectively none for California-bound volumes.

[Transwestern Pipeline] [Capacity Constraint] GUYMAN POINT GROUP

SEV 4/5
Force Majeure 1 Days

Transwestern Pipeline has declared Force Majeure at the Guyman Point Group, effective June 6 2026 at 9:00 AM through June 7 2026 at 8:59 AM -- a one-day event. No specific capacity volume is stated in the notice. Guyman Point Group is a receipt cluster on the Transwestern system in the Oklahoma/Texas Panhandle/San Juan Basin corridor, meaning gas cannot move westbound toward SoCal border and Arizona delivery points.

TW force majeure at Guyman Point Group constrains westbound capacity toward SoCal Border and Arizona for approximately one day; expect mild bullish pressure at SoCal Border with corresponding bearish pressure at Guyman/Panhandle receipt-side points -- no capacity figure provided limits sizing of the move.
Reroute: Moderate: EPNG is the primary competing pipeline serving SoCal border and Arizona delivery points from the Southwest corridor, and likely has some spare capacity to absorb displaced Transwestern volumes for a one-day event. However, if EPNG is simultaneously constrained, no California reroute exists.

[OPERATIONAL FLOW ORDER] SOC System Wide Pack - Update #1

SEV 3/5
Operational Alert Until Further Notice 1 Days

EPNG has issued a System-Wide Pack Operational Flow Order effective 06/01/2026 at 9:33 AM through 06/02/2026 at 9:00 AM. The OFO requires shippers to maintain or increase system line pack across the entire EPNG system, restricting nomination flexibility for one day. No specific capacity volume is stated in the notice.

EPNG system-wide pack OFO constrains shipper scheduling flexibility across the full Permian-to-California corridor for approximately one day; expect mild bearish pressure at Waha as outbound nominations are restricted, with modest bullish signal at SoCal Border and Arizona delivery points if westbound throughput is curtailed.
Reroute: Moderate: Transwestern Pipeline (TW) serves overlapping SoCal border and Arizona markets and can absorb some displaced Permian westbound volumes, though pack OFOs typically reflect system-wide stress that may limit the degree of reroute benefit.
