Headline day-0 abnormal return oil-augmented · Patell p = 0.049
Section I
The article
ExxonMobil announced on March 10, 2026 that it would seek shareholder approval to reincorporate from New Jersey to Texas. The proposal goes to a vote at the company's annual meeting on May 27, 2026. Critics framed the move as an exit from shareholder accountability. The proxy disclosures, the elective-provision menu Texas opens up under SB 29 and SB 1057, and the announcement-window market data each tell a more specific story.
The article asks one question: what does ExxonMobil's DEF 14A actually commit to, and how did the market price it?
The answer turns on three statutes (Tex. Bus. Orgs. Code §§21.373, 21.552(a)(3), and 21.419), two verbatim commitments by the company, and a 240-day pre-event estimation window applied across three benchmarks. Every number on this page resolves to a primary source on EDGAR, a state statutory compilation, or a federal court opinion.
What the proxy actually says
"The Company is not adopting any elective provisions of the Texas corporate statute that weaken shareholder rights as compared to New Jersey law in connection with the Texas Redomiciliation."
"no provision of the New Jersey Business Corporation Act limits a corporation's ability to adopt eligibility and procedural restrictions on shareholder proposals."
What the company is not adopting
TBOC §21.552(a)(3) — opt-in derivative-suit ownership threshold up to 3 %. ExxonMobil's bylaws do not invoke it.
TBOC §21.373 — opt-in shareholder-proposal eligibility threshold ($1 million or 3 %). ExxonMobil's bylaws do not invoke it.
The DEF 14A commits, in writing and subject to Rule 14a-9 antifraud liability, that no elective Texas provision will weaken shareholder rights relative to the New Jersey baseline. The commitment is operative whether or not the company subsequently changes bylaws — a later bylaw amendment that contradicted the commitment would expose the company to securities-law liability for the original proxy.
What the market told us
Across three benchmarks — synthetic control on a 21-donor energy peer pool, matched-pair with Chevron, and an oil-augmented market model — the announcement-window day-0 abnormal return ranges from -0.11% (synthetic control, placebo p = 0.955) to -2.19% (oil-augmented, Patell p = 0.049). The headline negative result attenuates substantially once XOM's correlated oil-price exposure is controlled for through the synthetic-control donor weights; the synthetic-control placebo distribution places ExxonMobil's actual day-0 gap well inside the 21-donor pseudo-treatment envelope (rank-based p = 0.955).
The article version cited in the May 12, 2026 DEFA14A is v17 (April 2026). This page tracks v17 verbatim where the article and the canonical pipeline agree; where they diverge, the canonical pipeline wins and the divergence is noted. See methodology and reconciliation at the bottom of this page.
Section II
The evidence
Seven panels, each rendered from canonical data (v3.60) where possible, and from the article (v17) where not. Source attribution sits below every figure.
Synthetic-control donor weights — two specifications, side by side
Left panel — article pre-registered (10-donor restricted simplex). Chevron carries 41.70%, with Diamondback (14.70%) and EOG (13.50%) the next-largest contributors. Day-0 abnormal return = 0.021%. Right panel — v3.60 canonical (21-donor unrestricted simplex). The pipeline solver concentrates weight on Chevron (54.86%) and EOG (19.83%); top-seven donors carry the full 100 %. Day-0 abnormal return = -0.11%. Both specifications return economically zero, statistically null effects within the project's ±0.5 pp reproducibility tolerance.

Reconciliation. The page now renders BOTH synthetic-control specifications. (1) Article pre-registered 10-firm pool (CVX 41.7%, FANG 14.7%, EOG 13.5%, SLB 7.8%, WMB 5.6%, BKR 4.5%, OXY 3.4%, COP 2.2%, MPC 1.7%, PSX 1.7%; Day-0 AR +0.021%) is the published headline from Goodwin v17, fn. 27. (2) v3.60 canonical 21-donor unrestricted simplex (CVX 54.86%, EOG 19.83%, SLB 9.38%, WMB 8.37%, COP 3.63%, OXY 2.94%, CTRA 0.99%; Day-0 AR -0.11%) is the pipeline output. Both lie within the project's ±0.5 pp tolerance band; both are economically zero and statistically null. The 10-donor specification is the canonical published headline; the 21-donor specification is the canonical pipeline output used as a documented robustness check.
ExxonMobil vs. synthetic control — tracking and post-event divergence
Pre-period R² = 0.77; pre-period RMSPE = 0.75%; post-period RMSPE = 0.66% (ratio = 0.88). Tight pre-period fit, no divergence at the announcement.
Schematic chart — RMSPE values canonical (v3.60).
Cumulative gap with placebo envelope
Day-0 gap = -0.11%; rank-based placebo p = 0.955. ExxonMobil's actual gap sits comfortably inside the 21-donor pseudo-treatment envelope.
Day-0 point and placebo p canonical (v3.60); envelope schematic.
Rank-based p = 0.920; 92 % of pseudo-dates produced absolute ARs larger than the actual announcement.
Source: Goodwin v17, §4.5 (article-derived).
ExxonMobil vs. Chevron — 11-day co-movement window
Day-0 raw differential = 0.13%; signs agreed on 10 of 11 days (binomial p = 0.012). The day-0 abnormal return is statistically indistinguishable from CVX (matched-pair p = 0.958).
Differentials canonical (v3.60); chart schematic.
Interested-stockholder threshold — NJ baseline vs. DE vs. TX outcome
NJ triggers at 10 % and imposes a perpetual fair-price condition; DE triggers at 15 %; TX triggers at 20 % with no perpetual fair-price condition. The Texas threshold is the most permissive of the three.

Combinatorial counts reproduced against the same workbook per Goodwin, Audit memo #14 (Coalition arithmetic rerun, 2026-05-16), using a 13F-family nonzero-holder methodology (Source ∈ {13F, Aggregated 13F, Exchange Announcement, Multiple}; duplicates consolidated; zero-share holders excluded). On 4,869 unique 13F-family holders (3,135 at or above $1 mm market value, 64.4 %), 14,631 two-firm combinations clear 3 %, 35,672,269 three-firm combinations clear 3 %, and 57,973,531,643 four-firm combinations clear 3 %. Excluding the Big Three entirely, 30 two-firm pairs still clear 3 % (anchor: FMR LLC 2.380% + Geode Capital Management, LLC 2.314% = 4.694%); 148,035 ex-Big-Three triples and 365,062,262 ex-Big-Three quads clear 3 %. These figures supersede the v17 §6 counts (15,207 / 38.5 M / 65.1 B against the 12/31/2025 universe); the substantive thesis is unchanged: a 3 % derivative threshold is reachable by any of thousands of plausible institutional combinations, with or without the Big Three.

Index-tracking institutions (Vanguard, BlackRock, State Street, Geode) account for the dominant passive bloc; active managers are atomized across more than 3,800 accounts. The split matters for any coalition argument: passive holders typically vote management slate by default but follow ISS/Glass‑Lewis on contested items, while active managers vote on idiosyncratic frameworks.

Source-of-truth hierarchy. This page renders from the SMU CGI Reincorporation Tracker canonical pipeline (DExit_Central_Database_v3.60.xlsx, generated April 29, 2026). Where the article (Goodwin v17) and the canonical pipeline diverge, the canonical pipeline is the source of truth on this page; the divergence is noted below.
Article vs. canonical — substance. All headline numbers (oil-augmented day-0 AR = -2.19%, Patell p = 0.049, Corrado p = 0.107, wild-bootstrap p = 0.057, market-only day-0 AR = -1.55%, sign test 10/11 p = 0.012, placebo p = 0.955, pre/post RMSPE ratio = 0.88) agree between Goodwin v17 and DExit Central Database v3.60. The synthetic-control donor specification differs: v3.60 uses a 21-donor energy peer pool with CVX 54.86%, EOG 19.83%, SLB 9.38%, WMB 8.37%, COP 3.63%, OXY 2.94%, CTRA 0.99% (sum = 100%); the article references an earlier 22-donor specification. Both specifications produce a day-0 gap statistically indistinguishable from zero (canonical -0.11%, placebo p = 0.955); the inference is identical. The site renders the v3.60 canonical specification as the source of truth and notes the article's prior specification in the methodology footnote.
Article-derived extensions. These are article-derived statistics (Goodwin v17 §§4.3–4.5) not currently materialized as fields in canonical v3.60. The figures on this site cite the article section and link to the PDF. They will be promoted to canonical fields in the next pipeline run.
EDGAR verification. All four accessions on this page were verified against data.sec.gov/submissions/CIK0000034088.json at build time. Build aborts on any mismatch in accession number, form type, primary document, or filing date.
Cross-version stability. XOM's record in v3.30 (2026-04-28) and v3.60 (2026-04-29) is numerically identical; only audit-note prose and EDGAR-accession formatting differ.
