Data trap
DTE Energy did not restate for the separation until the third quarter of 2021, and said so explicitly: results through June 30, 2021 still include DT Midstream. Any DTE revenue, earnings or segment figure from a filing before that restatement is a combined-company number. Separately, DT Midstream took on 2.1 billion dollars of senior notes and a 1.0 billion dollar term loan in June 2021 and paid DTE a 501 million dollar dividend before separating, so its pre-spin balance sheet does not describe the company that began trading.
The restated filings have landed; this is kept as history.

Performance since separation
| DT Midstream, Inc. since separation | +201.69% |
|---|---|
| DTE ENERGY CO over the same window | +20.86% |
| S&P 500 (SPY) over the same window | +77.90% |
| Russell 2000 (IWM) over the same window | +29.63% |
| Excess over the S&P 500 | +123.79% |
| Excess over the Russell 2000 | +172.06% |
Measured from the first regular-way close on or after the distribution — 2021-07-01 at 42.02 — to 2026-08-21 at 126.77. Window: 5.1 years. Two benchmarks, because one is misleading: spin-offs are usually small companies, and across this period small caps lagged the S&P by several points a year on their own. Measured against the S&P alone, roughly a third of any shortfall is company size rather than the separation. Returns are arithmetic over end-of-day closing prices. Unlike every other figure on this page, they do not come from a filing.
Pre-distribution investor return
| Parent, announcement to separation | price history starts after the separation |
|---|---|
| Combined (DTE ENERGY CO + DT Midstream, Inc.), pre-distribution to now | +80.11% |
| Combined excess over the S&P 500 | +1.23% |
| Combined excess over the Russell 2000 | +49.33% |
Combined treats a pre-spin holding as 1 DT Midstream share for every 2 DTE Energy shares valued at the parent's last close before regular post-spin trading resumed — 2021-06-30 at 110.27 — against that same basket today. That baseline is a practical proxy, not an attempt to isolate exactly how much value the separation transferred: for a large parent and a small spinco, ordinary day-to-day price noise can be bigger than the transfer itself.

Notes
DTE Energy's separation of its non-utility natural gas pipeline, storage and gathering business, distributing all of DT Midstream. Classified focus-increasing: the parent becomes a pure regulated electric utility and the spinco a midstream operator, businesses with different customers, different regulation and different risk, even though both sit in the two-digit SIC 49 utilities bucket.
