A UAW unfair labor practice strike at a tier-one axle supplier has GM's Fort Wayne Assembly plant staring at an inventory clock that historically runs in days, not weeks. That's the lead story today — but it shares a feature with two others: the decision window is short, and the intervention options narrow fast once the trigger event hits.

UAW Strike at Dauch — GM Fort Wayne's Axle Clock

The UAW has filed an unfair labor practice strike against Dauch, a tier-one axle supplier serving GM's Fort Wayne Assembly plant. GM Fort Wayne typically maintains days of axle buffer inventory, not weeks — and the plant has already gone idle twice over axle supply disruptions, in 2023 and 2024. If you're in that supply chain, this is an active production risk requiring immediate inventory and scheduling review. It is not a watch-and-wait situation.

IURC Rate Investigation — The Action Window Is Nearly Closed

IURC Chair Andy Zay committed in late April to action within 30 to 60 days, following a 10-session statewide listening tour. The Indiana Energy Growth Task Force's state energy growth plan landed May 29th, adding a fresh data layer to what the commission is now working with. That clock is almost out.

The Illinois parallel is worth understanding. People's Gas just filed to raise rates an additional $10 to $11 per month in 2027, citing the need to replace 1,000 miles of aging pipe. The Illinois Attorney General didn't just push regulators to deny the $202 million proposed hike — he pushed to cut current rates by $4.1 million. The structural driver is the same in Indiana: utilities earn a return on capital invested, so every infrastructure replacement they authorize increases their approved profit. Allison Transmission, Eli Lilly, Marathon Petroleum, and Walmart are already formal interveners in active IURC proceedings. If your electricity costs have crossed from background noise to a material operating concern, the time to access formal intervention in the next rate case affecting your primary utility is before the next filing. Not after.

ITIF Report — Indiana's Turbine Cluster Is in Chinese Competition's Crosshairs

The Information Technology and Innovation Foundation published a state-by-state assessment June 1st on how Chinese industrial policy is eroding U.S. manufacturing competitiveness. Indiana leads the nation in engine, turbine, and power transmission equipment manufacturing (NAICS 3336) with 10,431 workers — ahead of California and Michigan. The anchor firms are Rolls-Royce, with roughly 4,000 employees at its Indianapolis operations campus, and Cummins, headquartered in Columbus.

The structural risk the state-level report doesn't surface: Cummins' own fiscal year 2025 filings name Waikai Power as a direct competitor, and the ITIF brief documents that Waikai Heavy Machinery has doubled revenue in segments that overlap directly with Cummins Power Systems. Cummins simultaneously operates active joint ventures with Chinese partners — Dongfeng and Beijing Photon — that share platforms and IP inside China. The competitive and JV relationships are treated as separable in Cummins' own filings. ITIF flags that contradiction directly. If you're a precision machined components supplier in Cummins' Indiana supply base, start tracking whether your customer's export order volumes are softening now — before it shows up in your domestic releases.

Questions for Your Morning Huddle

Q: How quickly could GM Fort Wayne go idle if the UAW strike extends? A: GM Fort Wayne Assembly typically runs days of axle buffer inventory, not weeks. The plant idled in both 2023 and 2024 over axle supply constraints — if you're in that tier-one or tier-two supply chain, treat this as an active production risk requiring immediate inventory and scheduling review.

Q: When will the IURC act on Indiana utility rates? A: IURC Chair Andy Zay committed to action within 30 to 60 days of late April 2025 following a 10-session statewide listening tour. That window is nearly closed. Indiana manufacturers with energy costs that have become a material concern should be tracking the next rate case filing for their primary utility now, not after the filing drops.

Q: What does the ITIF report mean for Indiana manufacturers in the engine and turbine supply base? A: Indiana leads the nation in engine, turbine, and power transmission manufacturing with 10,431 workers. The ITIF report flags that Waikai Heavy Machinery — a state-subsidized Chinese competitor — has doubled revenue in segments overlapping Cummins Power Systems, while Cummins simultaneously runs joint ventures with Chinese partners. Tier-one and tier-two suppliers in that cluster should be monitoring export order volumes now for early signals before they appear in domestic releases.
