Visual evidence — event study around the announcement

Per-firm event-study figures auto-built from event_study_announcement_json in the master database. Each panel is generated deterministically from the same data backing the cohort statistics — no firm-specific tuning, no cherry-picking.

eXp World's announcement-day move was a non-event

**Bottom line.** All four ways of looking at eXp World's stock that day point to roughly the same answer: barely moved by about 0.3%, and the move was statistically indistinguishable from a normal trading day (p = 0.92).

This chart shows four different statistical lenses on what eXp World's stock did on the day the reincorporation was announced. Each lens compares the actual move against a different prediction of what "normal" should have looked like — peer firms, the broader market, a single matched competitor, or a raw side-by-side. The gold-edged bar marks the lens used in the cohort summary.

Method

Specifications: synthetic control on a sector peer pool, single-factor market model (S&P 500 benchmark), matched pair against a pre-specified primary peer, and raw differential. Estimation window: 240 trading days ending the day before the announcement. Standard errors via Patell-z (1976).

For eXp World, the announcement-day move sat right inside its normal noise

**Bottom line.** eXp World's announcement-day reading falls near the center of its day-to-day trading range over the prior year. Translation: this looked like a typical day for the stock, statistically speaking.

This histogram shows every daily move eXp World's stock made over the 240 trading days *before* the announcement. The red line marks the announcement-day reading. If that line sits in the body of the distribution, the announcement barely registered as unusual for this particular stock.

Method

Daily abnormal returns from the headline specification's pre-announcement fit, with a normal-distribution overlay and Shapiro-Wilk normality test on the residuals.

eXp World sits near the middle of the 36-firm cohort

**Bottom line.** eXp World's announcement-day reading is close to the cohort-wide mean of +0.69%. Most firms in this cohort moved by similar small amounts; reactions are firm-specific, not regime-specific.

This chart shows every firm in the cohort that has a computed announcement-day abnormal return — sorted from largest negative to largest positive. eXp World is highlighted in gold. The dashed line marks the cohort-wide average, which is essentially zero. Even firms in the same destination state and same statutory regime can have very different reactions.

Method

Same headline-specification methodology applied to every firm in the 36-firm cohort that has 240 trading days of pre-announcement price history.

Event-study abnormal returns — announcement window

Returns around the announcement date.

Event date: 2026-02-20 · Estimation window: 2025-03-07 to 2026-02-19 (240 days)

Specification	Day-0 AR	Inference
Synthetic control (18-donor Real Estate peer pool)i	+1.09%	no inference
Market model (SPY benchmark)i	+0.10%	Patell-z p-value = 0.972

Raw differential vs CBREi	+2.13%	no inference

Robustness checks — does the headline result hold up?

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 -0.0028% per day in the pre-event window (p = 0.329). 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: 11 of 18 peer firms moved in the same direction as the treated firm on the event day (binomial p = 0.4807). — 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 = 0.484 (weak tracking — interpret with caution); R² = 0.068 (fraction of pre-event variance explained); Durbin-Watson = 2.29 (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 selection-corrected ATE · Romano-Wolf step-down + BH FDR · pooled BHAR. This firm's reading is shown in context of the full cohort.

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 = 0.919, 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)

Texas Statutory Adoptions

Texas opt-in statutory regimes available to Texas-incorporated public companies. Each requires a charter or bylaw amendment with proxy notice. Both are independently elected.

SB 29 — TBOC §21.552

Derivative-action 3% ownership threshold (effective 2025-05-14, post-Tornetta v. Musk).

○ NOT ADOPTED

SB 1057 — TBOC §21.373

Shareholder-proposal threshold: lesser of $1M market value or 3% of voting shares, 6-month hold, 67% solicit (effective 2025-09-01). Director nominations and procedural resolutions are exempt. Legal status: vulnerable to challenge under the Internal Affairs Doctrine and dormant Commerce Clause; SEC Rule 14a-8(i)(1) permits state-law exclusion, so §21.373 may operate through Rule 14a-8 rather than face direct preemption. No court ruling has issued. Firms appear to be in a wait-and-see posture pending legal clarity.

PENDING VERIFICATION

Adoption is opt-in. A "No" or "Pending" status means the firm has not (yet) elected into the regime — it does not mean the firm is non-compliant. Adoption requires a charter/bylaw amendment disclosed via 8-K Item 5.03.
