Event-study abnormal returns — announcement window
| Specification | Day-0 AR | Inference |
|---|---|---|
| Synthetic control (20-donor Information Technology peer pool)i | -1.40% | no inference |
| Market model (SPY benchmark)i | -1.78% | Patell-z p-value = 0.833 |
| Sector-augmented model (SPY + Nasdaq-100 (QQQ)) HEADLINEi | -1.97% | Patell-z p-value = 0.814 |
| Matched pair (vs ADBE, market-model-adjusted)i | +0.09% | two-sided p-value = 0.992 |
| Raw differential vs ADBEi | +0.29% | no inference |
Three independent diagnostics that interrogate the headline estimate from different angles. All three pointing the same way = high confidence in the result.
- Pre-event drift check: the firm's daily abnormal return drifted by +0.0008% per day in the pre-event window (p = 0.918). no detectable pre-event drift ✓. — A near-zero slope means the pre-event period was stable, so the day-0 reaction is not contamination from a pre-existing trend.
- Donor co-movement check: 9 of 20 peer firms moved in the same direction as the treated firm on the event day (binomial p = 0.8238). — A high concordance means the day was driven by industry-wide news rather than something firm-specific. A low concordance means the firm moved differently from peers (potential firm-specific signal).
- Synthetic-control fit quality: pre-event correlation between the firm and its synthetic twin = -0.471 (weak tracking — interpret with caution); R² = -2.788 (fraction of pre-event variance explained); Durbin-Watson = 2.01 (no autocorrelation). — Higher correlation + higher R² + Durbin-Watson near 2 means the synthetic peer was a good match before the event, so the post-event gap is interpretable.

Cohort-level robustness battery
Heckman two-step selection correction (controlled-vs-widely-held)
Cohort ATE = +0.94% (SE = 7.06%, n = 2395) after correcting for controller-status selection (inverse Mills ratio = -0.062).
Romano-Wolf step-down + Benjamini-Hochberg FDR (n = 47)
This firm: raw p = 0.814, Romano-Wolf adjusted p = 1.000, BH-FDR adjusted p = 0.966. Multiple-hypothesis correction is computed across the full cohort to control family-wise error rate at alpha = 0.05.
Pooled cohort BHAR (mover firms only)
BHAR_63d: mean = -5.60% (SE = 22.11%, n = 3, p = 0.499) · BHAR_126d: mean = +17.33% (SE = 41.17%, n = 3, p = 0.774)

Nevada Statutory Disclosures
Primary-source pending. Where badges read “PENDING VERIFICATION,” the firm-specific adoption posture (e.g., charter carve-outs to NRS § 78.138, opt-outs from NRS §§ 78.378–3793 or 78.411–444) has not yet been extracted from the firm’s amended-and-restated articles or proxy materials. The presence of a Nevada incorporation alone does not establish adoption of every provision; opt-outs are charter-level facts.
