[FORCE MAJEURE] FORCE MAJEURE-REMEDIATION-CS34 -UP3
SEV 4/5
Force MajeureUntil Further Notice1 Days
NGPL has declared a force majeure at Compressor Station 34 (Unit 3) effective June 11, 2026 at 3:21 PM, with restoration targeted for June 12, 2026 at 9:00 AM -- approximately 18 hours of impact. No specific capacity volume is stated in the notice. CS34 is located on NGPL's Gulf Coast-to-Midwest mainline corridor, and the unit outage constrains northbound throughput.
NGPL force majeure at CS34 Unit 3 constrains Gulf Coast-to-Chicago northbound capacity; expect bearish Henry Hub pressure as gas backs up at Gulf Coast origin points and bullish Chicago Citygate and NGPL Midcontinent basis versus Henry Hub for the duration.
Reroute: Moderate: ANR, PEPL, and REX Zone 3 serve overlapping Chicago and Midwest markets and may absorb displaced volumes, though NGPL is very high capacity and a compressor outage of unknown magnitude may not be fully offset by alternatives.

Force MajeureUntil Further Notice14 Days
NGPL has declared a force majeure event affecting Compressor Station 341 (CS341) on the UP4 segment, effective immediately on 06/16/2026 with a stated end date of 06/30/2026. No specific capacity volume is provided in the notice. CS341 is a key compression point on NGPL's Gulf Coast-to-Midwest corridor, and this FM declaration indicates an unplanned equipment failure or emergency condition requiring remediation over approximately 14 days.
NGPL CS341 force majeure on UP4 segment tightens northbound Gulf Coast takeaway capacity, expect bearish pressure at Henry Hub as gas backs up onshore with bullish pressure at Chicago Citygate and NGPL Midcontinent basis; no volume stated but CS341 outages on NGPL can materially affect one of the highest-throughput Midwest corridors.
Reroute: Moderate: ANR, PEPL, and REX Zone 3 serve overlapping Gulf Coast-to-Chicago/Midwest corridors and may absorb some displaced volumes, but NGPL is very high capacity and a full reroute of all affected volumes is unlikely given typical spare capacity constraints on competing pipes.

SEV 4/5
Force MajeureUntil Further Notice1 Days
NGPL has declared a force majeure at Compressor Station 341 (CS341), effective June 22, 2026 at 11:24 AM, with restoration expected by June 23, 2026 at 9:00 AM. The notice is a first revision (fresh event) with no capacity volume stated. Duration is approximately one calendar day. CS341 is on the NGPL mainline, a high-throughput Gulf Coast-to-Midwest corridor pipeline.
NGPL force majeure at CS341 restricts northbound Gulf Coast-to-Midwest throughput; expect bearish Henry Hub pressure as Gulf Coast supply backs up and bullish pressure at Chicago Citygate and NGPL Midcontinent basis -- no capacity volume stated so magnitude is uncertain but force majeure classification warrants close monitoring.
Reroute: Moderate: ANR, PEPL, and REX Zone 3 serve overlapping Gulf Coast-to-Midwest corridors and may absorb some displaced volumes, but NGPL is one of the highest-capacity Midwest pipelines and partial offsets are likely insufficient for large displacements.

Force Majeure32 Days
NGPL has declared a force majeure on the M&M Lateral segment between MLV2 and MLV3, effective 07/30/2026 with an end date of 08/31/2026 -- a roughly 32-day event. This is Revision 5 of the notice, but the force majeure designation remains active, triggering the escalation rule and requiring fresh high-severity treatment. No specific capacity volume is stated in the notice text.
Active force majeure on NGPL M&M Lateral (MLV2 to MLV3) through 08/31/2026 reduces Gulf Coast-to-Midwest takeaway on one of the highest-throughput Midwest pipelines; expect bearish pressure at Henry Hub and Gulf Coast origin points with bullish widening at Chicago Citygate and NGPL Midcontinent basis.
Reroute: Moderate: ANR, PEPL, and REX Zone 3 serve overlapping Gulf Coast-to-Midwest corridors and may absorb some displaced volumes, but NGPL is very high capacity and a large constraint on this lateral is difficult to fully offset on alternative pipes.

· Impacted pipeline segments
· Estimated start and finish dates
· Brief project descriptions
· Anticipated shipper impacts
Changes to existing projects and newly added projects are highlighted in yellow for easy reference. In addition, Natural will continue to post detailed updates on specific maintenance projects with direct shipper impacts on its interactive website as needed.

Outage Impact Report -7-23-26
If you have any questions, please contact your Account Director or Scheduling Representative.
NGPL has posted a maintenance outage impact report effective June 23, 2026 at 9:43 AM through June 24, 2026 at 9:00 AM -- a roughly 23-hour window. No specific location, segment, compressor station, or capacity restriction figure is provided in the notice text. The event appears to be a short-duration planned maintenance with advance notice and a known end date.
Short-duration planned NGPL maintenance with no stated capacity volume and no segment detail -- insufficient information to assess basis impact at NGPL Midcontinent or Chicago Citygate; monitor for follow-on revision with capacity figures.
Reroute: Moderate: if capacity is affected, ANR, PEPL, and REX Zone 3 serve overlapping Gulf Coast-to-Midwest corridors, though NGPL is very high capacity and large constraints are difficult to fully offset; no specific volume or segment is disclosed in this notice.
Below alert threshold -- no detailed analysis performed.
Reroute: Not assessed.

SEGMENT 26 – GULF COAST #3 M/L - ILI TOOL RUNS – UPDATE 1
The tool run dates have been revised, as noted below. See previous Notice ID 47016 dated June 11, 2026.
As previously posted on Natural's Outage Impact Report (X25-1432007) and as part of Natural's ongoing pipeline Integrity Management Program, Natural will perform a series of ILI tool runs on the Gulf Coast #3 Mainline between Compressor Station 303 (CS 303) located in Angelina County, Texas, and Compressor Station 302 (CS 302) located in Montgomery County, Texas, in Segment 26 of Natural's Texok Zone.
As such, effective on the gas days indicated below, Natural will schedule Primary Firm and Secondary in-path Firm transports to no less than 59% of contract MDQ southbound through CS 303. AOR/ITS and Secondary out-of-path Firm transports will not be available for the duration of this restriction. For scheduling purposes, the Texok GC Pool (LOC 10560) is located north of the constraint. Firm transportation associated with storage injections and withdrawals may be impacted. Once the data from the tool runs have been analyzed, any remediation work impacting shippers will be posted.
TOOL RUN DATES:
Gas day Wednesday, August 5, 2026 (Previously Gas day Tuesday, August 4, 2026)
Gas day Friday, August 7, 2026 (Previously Gas day Thursday, August 6, 2026)
