Current FY2026 EBITDA is $303K against $452K in Prior, a change of ($149K), or (32.9%). The script's walk reconciles to that change. I wrote the note to `output/drivers-note.md` and the figures to `output/drivers.json`.

Three of the six drivers changed:

| Driver | Prior | Current | Months changed | EBITDA delta |
| --- | --- | --- | --- | --- |
| Active customers | 46 | 44 | 12 | ($133K) |
| Gross margin | 26.2% | 26.6% | 12 | $39K |
| Headcount | 23.00 | 23.75 | 9 | ($54K) |

- **Active customers** carries the move. It also accounts for the whole revenue change, from $11.7M to $11.2M, a change of ($509K).
- **Gross margin** and **headcount** partly offset or add to it, as the deltas above show.
- **Revenue per customer**, **Cost per head** and **Other opex** did not change, so their deltas are $0.

The data shows what moved but not why. The Review section asks each driver's owner which documented assumption supports the change. The note is built from `drivers_fy2026.csv` (144 rows, sha256 `704c929028e8`).
