Event-study abnormal returns — announcement window

Returns around the announcement date.

Event date: 2026-02-12 · Estimation window: 2025-02-28 to 2026-02-11 (240 days)

Specification	Day-0 AR	Inference
Synthetic control (12-donor Information Technology peer pool)i	+0.58%	no inference

Sector-augmented model (SPY + Nasdaq-100 (QQQ)) HEADLINEi	+1.50%	Patell-z p-value = 0.610
Matched pair (vs TENB, market-model-adjusted)i	+1.28%	two-sided p-value = 0.713
Raw differential vs TENBi	+0.96%	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 -0.0014% per day in the pre-event window (p = 0.654). no detectable pre-event drift âœ“. — 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: 12 of 12 peer firms moved in the same direction as the treated firm on the event day (binomial p = 0.0005). — 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 = 0.869 (good tracking); RÂ² = 0.354 (fraction of pre-event variance explained); Durbin-Watson = 2.08 (no autocorrelation). — Higher correlation + higher RÂ² + 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 = 0.610, 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

Nevada Revised Statutes (NRS) governance provisions relevant to Delaware→Nevada redomestications. Five sections summarized; each links to the Nevada Legislature’s authoritative NRS text. Counterpart to the Texas § 21.552 / § 21.373 panel for TX-destination firms.

NRS § 78.138 — Director / officer fiduciary duty

Codifies the business-judgment rule and limits monetary liability of directors and officers absent breach of loyalty, intentional misconduct, fraud, or knowing violation of law. Stronger statutory shield than DGCL § 102(b)(7) on its face; charter opt-out / carve-out is firm-specific.

PENDING VERIFICATION

Adoption with carve-out by Datadog, Inc.: primary-source verification pending; canonical record not yet populated.

NRS § 78.7502 — Indemnification of directors / officers

Broad permissive indemnification statute; covers expenses, judgments, fines, and amounts paid in settlement for any action by reason of service as director or officer, subject to good-faith standard. Charter / bylaw uptake is firm-specific.

PENDING VERIFICATION

Datadog, Inc. indemnification provisions pending charter / bylaw extraction.

NRS §§ 78.378–3793 — Acquisition of controlling interest

Nevada's control-share acquisition statute (anti-takeover): voting rights of shares acquired in a “control-share acquisition” are extinguished absent disinterested-shareholder approval. Opt-out is by charter or bylaw amendment; default is opt-in for Nevada corporations meeting the statute's coverage thresholds.

PENDING VERIFICATION

Datadog, Inc. opt-in / opt-out status pending charter or bylaw verification.

NRS §§ 78.411–444 — Combinations with interested stockholders

Nevada's business-combination statute (anti-takeover): for two years post-acquisition, a Nevada corporation may not engage in a “combination” with a 10%+ interested stockholder unless the board pre-approved the transaction. Charter opt-out available.

PENDING VERIFICATION

Datadog, Inc. opt-in / opt-out status pending charter verification.

NRS § 92A.135 — Conversion mechanism (DGCL § 266 analog)

Authorizes conversion of a foreign business entity into a Nevada domestic entity by filing articles of conversion. The Nevada analog to DGCL § 266 (Delaware) and TBOC §§ 10.101–108 (Texas). Where used, the firm's redomestication is a true legal-entity conversion rather than a reverse-triangular merger.

PENDING VERIFICATION

Mechanism (§ 92A.135 conversion vs. merger-with-NV-sub) pending primary-source verification.

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.
