Three regulatory deadlines are landing inside 35 days for Indiana manufacturers — the AES Indiana rate increase ruling on June 24, the USMCA renegotiation deadline on July 1, and Steel Dynamics Q2 earnings on July 20 — and the cost inputs behind all three are moving against you simultaneously. If your margin assumptions for the second half of 2026 were built before April, they may already be wrong. Here's what's happening and what to do before each deadline closes.

AES Indiana's Rate Increase Is Stacking Three Cost Layers Simultaneously

The IURC approved a $9.52 per month Fuel Adjustment Clause surcharge on May 27 to recover Winter Storm Fern costs. AES filed a second FAC request on June 12 — an additional $8.04 per month, targeted for September through November 2026, with an August hearing expected. The June 24 IURC ruling on AES's $193 million base rate request lands on top of both. Three separate cost layers, one utility, one month. The structural exposure buried under the surcharge math: AES Indiana's generation mix is shifting toward natural gas post-Petersburg coal-to-gas conversion, which means future FAC exposure will track gas price volatility more directly than coal did. Quantify your kilowatt-hour exposure against the June 24 ruling before it lands. The pending BlackRock-led transaction involving AES Corp. is also worth tracking — the June 24 ruling sets rate structure for a potentially changing ownership entity.

USMCA's July 1 Deadline Hits Elkhart Where It's Already Bleeding

Thor Industries reported a 470-basis-point gross margin compression and a 25 percent drop in North American shipments — and that was before Commerce eliminated the Section 232 product exclusion request process. The primary administrative channel for component-level tariff relief is gone. FTZ, drawback, and Chapter 98 strategies remain available, but they require trade counsel review before July 1, not after. Identify every component that previously carried Section 232 exclusion protection and price the full tariff cost into your H2 assumptions now. Steel Dynamics reports Q2 earnings July 20, with its Columbus aluminum ramp targeting 60,000 to 70,000 tons — the USMCA exposure on its San Luis Potosi slab center has not been a focus in recent analyst commentary and is worth your own assessment before earnings land.

Boston Scientific's Plainfield Hub Creates a Labor Market Deadline for Hendricks County Employers

Boston Scientific confirmed a 500,000-square-foot global distribution and light manufacturing facility at Plainfield Innovation Park — $138 million investment, up to 300 jobs, groundbreaking expected later in 2026. The proximity to the Spencer, Indiana campus (roughly 40 miles) is a compliance asset for FDA serialization and traceability requirements on Class II and III devices. The more immediate consequence for Hendricks County employers is the labor market it generates. Those 300 jobs compete directly with Amazon and FedEx near Indianapolis International — the second-largest FedEx hub in the world. Wage-rate pressure in that submarket could arrive 12 to 24 months before most employers see it coming. Benchmark your current warehouse and light-manufacturing compensation against the full competitive set now, before recruiting begins.

Questions for Your Morning Huddle

Q: How much are AES Indiana's stacked rate increases adding to my electricity costs right now?
A: AES Indiana is currently collecting a $9.52 per month Fuel Adjustment Clause surcharge approved in May, with a second FAC request for $8.04 per month pending for fall 2026. The IURC rules on AES's $193 million base rate increase on June 24 — that ruling sets the rate structure your accounts will operate under for the next several years, so quantify your kilowatt-hour exposure against all three layers before it lands.

Q: What should Indiana manufacturers do before the USMCA July 1 deadline?
A: Identify every component that previously carried Section 232 product exclusion protection — Commerce has closed that request process and those exclusions are not recoverable through the same channel. Price the full tariff cost into your H2 assumptions and review FTZ, drawback, and Chapter 98 options with trade counsel before July 1.

Q: What does the Nvidia-Coherent groundbreaking in Texas mean for Indiana specialty suppliers?
A: Nvidia used equity stakes and purchase commitments to lock up TSMC's advanced-packaging capacity during the H100 cycle, and it's running the same model now with Coherent to secure indium phosphide supply before co-packaged optics demand scales. Indiana specialty suppliers that could participate in a similar structure with an AI hyperscaler or large OEM should initiate that conversation now, before open-market sourcing becomes the only option available.

Indiana manufacturers heading into the second half of 2026 are managing electricity cost exposure, tariff structure changes, and labor market shifts at the same time. The June 24 AES Indiana rate increase ruling is the nearest hard deadline — audit your kilowatt-hour exposure before it lands.
