The episode this site tracks began with a single judicial opinion. In January 2024, Chancellor Kathaleen McCormick of the Delaware Court of Chancery (sworn in as Chancellor on May 6, 2021) issued the post-trial opinion in Tornetta v. Musk, rescinding Tesla's 2018 compensation award to Elon Musk on the ground that the process by which the Tesla board approved it had not satisfied the entire-fairness standard applicable to controlled-shareholder transactions.21 Within approximately four and a half months of the Tornetta opinion, Tesla's board had proposed, and Tesla's shareholders had approved, a reincorporation from Delaware to Texas. The Texas reincorporation was completed on June 13, 2024, per Tesla’s Q2 2024 Form 10-Q (accession 0001628280-24-032662) and the same-day Item 5.07 Form 8-K,21a and the cohort tracked on this site begins from that moment. It runs through ExxonMobil’s New Jersey-to-Texas redomestication — approved May 27, 2026, with 71.2 percent of votes cast in favor, and effective July 1, 2026.60 On December 19, 2025, the Delaware Supreme Court (sitting en banc) reversed the Chancery rescission remedy, reinstated the 2018 compensation award, awarded $1 in nominal damages, and replaced the $345 million fee award with a quantum meruit fee award set at four times counsel’s lodestar, remanding fee disputes to the Court of Chancery; the widely reported $54.5 million figure was Tesla’s proposed cap, not a court-fixed award (see footnote 21).
In 2025, the Texas Legislature passed Senate Bill 29, adding Texas Business Organizations Code section 21.419 (codified business judgment rule) and section 21.552(a)(3) (derivative-proceeding ownership threshold not exceeding 3 percent of outstanding shares) — both applicable to publicly traded corporations and to corporations with 500 or more shareholders that affirmatively elect to be governed by section 21.419 in their governing documents (effective May 14, 2025).22 Texas followed with Senate Bill 1057, adding Texas Business Organizations Code section 21.373, which permits nationally listed Texas corporations that elect to be governed by the section through their governing documents to impose heightened shareholder-proposal eligibility and solicitation requirements (effective September 1, 2025).23 The full Texas 89th Legislature corporate-governance package also includes Senate Bill 2337 (proxy-advisor regulation, Texas Business Organizations Code Chapter 6A, signed June 20, 2025), now subject to preliminary injunctions entered August 29, 2025 by Judge Alan D. Albright of the U.S. District Court for the Western District of Texas in ISS, Inc. v. Paxton, No. 1:25-cv-01160 (W.D. Tex.) and Glass Lewis & Co. v. Paxton, No. 1:25-cv-01153 (W.D. Tex.), each on First Amendment and preemption grounds, Senate Bill 2411 (officer exculpation), House Bill 19 (Business Court statutory creation, effective September 1, 2023; the court opened for filings September 1, 2024), and House Bill 40 (Business Court sunset removal and amount-in-controversy threshold reduction from $10 million to $5 million, effective September 1, 2025). Delaware responded with Senate Bill 21, which amended Sections 144 and 220 of the Delaware General Corporation Law, creating statutory safe harbors for conflicted-director, conflicted-officer, and controlling-stockholder transactions and tightening books-and-records procedure; the common-law Kahn v. M&F Worldwide Corp. framework remains relevant only where the statutory safe harbor does not govern or is not satisfied.24 The Delaware Supreme Court upheld SB 21’s safe-harbor and retroactivity provisions against certified constitutional challenge, en banc and unanimously, in Rutledge v. Clearway Energy Group LLC, No. 248, 2025 (Del. Feb. 27, 2026).61 Nevada updated Assembly Bill 239, clarifying controlling-stockholder fiduciary obligations and authorizing jury-trial waivers for internal corporate actions (effective May 30, 2025).25 The Delaware Supreme Court's February 2025 en banc opinion in Maffei v. Palkon holds that business-judgment review applies to a reincorporation vote approved on a clear day — that is, outside a pending or threatened transaction-specific conflict — on the doctrinal ground that the hypothetical and contingent impact of another state's corporate law on unspecified future corporate actions is too speculative to constitute the material, non-ratable benefit required to trigger entire-fairness review. The opinion should not be read as a blanket rule that all controller-backed reincorporations always receive business-judgment review; the Court expressly reserved the question of how the standard would apply where directors or controllers take articulable, material steps in furtherance of breaching fiduciary duties prior to redomesticating.26
The post-Rhee scholarship engaging this episode falls into six camps that this site keeps separately tagged in the references.
The confirmatory camp argues that the Delaware-Exit data, properly read, are consistent with Rhee. Stephen Bainbridge's 2025 piece in the Journal of Corporation Law, DExit Drivers, hand-collected the universe of Delaware-out reincorporations from 2012 through June 2024 and concluded both that the reasons firms gave for moving were implausible and that the absolute numbers were small.27 Andrew Verstein's 2025 SSRN working paper, The Corporate Census, with companion January 2026 HLS Forum update, reports that Delaware experienced thirty percent more incorporations in 2025 than in 2024, a finding flatly inconsistent with a serious Delaware-Exit narrative.28 Verstein's measurement is on new incorporations into Delaware; the cohort tracked on this site is a different population — existing public companies leaving their state of incorporation. The two findings can coexist: a sharp rise in new Delaware incorporations is consistent with a small, episodic outflow of large existing public companies, and neither result by itself resolves whether Delaware corporate law has the substantive market-value effect that the announcement-window literature is designed to test.
The contradicting camp argues that the cumulative market evidence from the Delaware-Exit episode and from the SB 21 announcement points the other way. Kenneth Khoo and Roberto Tallarita's August 2025 event study, published on the Harvard Law School Forum on Corporate Governance, reported a roughly 1.4 percent negative abnormal return across the top 1,000 Delaware-incorporated firms in the window around SB 21’s introduction (introduced February 17, 2025; event day February 18, 2025, the first trading day after), implying an aggregate market-value loss in the range of seven hundred billion dollars.29 Khoo and Tallarita measure the SB 21 announcement effect on the universe of Delaware-incorporated firms; the SMU cohort measures a different treatment — announcement-window market reactions for the small number of firms leaving Delaware, Texas, or New Jersey — on a different population. Those are different identification strategies addressed to different empirical questions, and the results are not in tension. Jessica Erickson, A.C. Pritchard, and Stephen Choi's 2025 SSRN working paper, Is Delaware Different? Stockholder Lawyering in the Court of Chancery, provides indirect support by documenting that plaintiffs' attorneys in Delaware Chancery cases are systematically over-compensated relative to comparable federal class actions, suggesting that Delaware's procedural environment has been generating real costs for which firms might rationally be willing to pay to escape.30
The controller-primacy camp reads the Delaware-Exit episode as a coherent doctrinal phenomenon driven by the rise of controlling-shareholder governance. Christine Hurt, Senior Associate Dean for Academic Affairs and Alan R. Bromberg Centennial Chair in Corporate, Partnership, Business, and Securities Law at SMU Dedman School of Law, in Texas, Delaware, and the New Controller Primacy, published in the Arizona Law Review, frames the episode as the emergence of a controller-favorable jurisdictional alternative.31 Michal Barzuza's 2024 ECGI working paper, Nevada v. Delaware: The New Market for Corporate Law, supplies the most thorough doctrinal counter-frame to Rhee on the Nevada side, focusing on the practical denial of books-and-records access that Nevada's procedural code creates for plaintiff-shareholders.32 Angela Aneiros's 2025 piece in the Baylor Law Review, Reincorporation: The Trojan Horse of Self-Dealing, advances the prescription — entire-fairness review for all controlled-company reincorporations — that the Delaware Supreme Court rejected in Maffei v. Palkon.33 Carliss N. Chatman, Professor of Law at SMU Dedman School of Law, and Carla L. Reyes's 2024 piece in the Stetson Law Review, Uncovering Elon's Data Empire, supplies the Tesla-specific governance critique from which the Delaware-Exit episode begins, mapping the cross-entity data and control structures that the Tornetta-era controlling-shareholder analysis was attempting to reach.45 Lucian A. Bebchuk and Kobi Kastiel's January 2026 working paper, Controllers Unbound, Harvard L. Sch. Discussion Paper No. 1186, forthcoming 105 Tex. L. Rev. (2027), advances the principal post-SB 21 shareholder-protection critique, arguing that the weakening of controller constraints in Delaware, Texas, and Nevada will produce material adverse effects for public investors by lowering the doctrinal price at which controlling-stockholder transactions, charter changes, and conflicted dealings can be transacted.59
The disenfranchisement camp reads the same episode through the lens of dispersed-shareholder voice. Sergio Alberto Gramitto Ricci and Christina M. Sautter, Associate Dean for Research and Professor of Law at SMU Dedman School of Law, in their forthcoming 2027 UC Irvine Law Review article Corporate Disenfranchisement, develop the "Leopard Paradigm" and frame the Delaware-Exit episode as a structural disenfranchisement of dispersed shareholders.34
The institutional-process camp situates the debate in the comparative architecture of corporate lawmaking — courts, legislatures, and the equilibrium between them. Zohar Goshen and Tomer Stein's 2025 piece in the Columbia Law Review, Leaving Delaware? The Essential Role of Specialized Corporate Courts, argues that the Delaware Court of Chancery's distinctive value lies less in the substantive doctrine it applies than in the institutional capacity of a specialized bench, and that the Texas Business Court and Nevada's specialized fora are not obviously equivalent substitutes.35 Eric Talley, Sarath Sanga, and Gabriel V. Rauterberg's February 18, 2025 piece on the CLS Blue Sky Blog, Delaware Law's Biggest Overhaul in Half a Century, characterized SB 21 as the most significant single-year revision of Delaware's corporate code since at least 1967 and warned that the bill amounted to a legislative rebuke of the Delaware judiciary.46 Marcel Kahan and Edward B. Rock's September 2025 working paper, The New Political Economy of Delaware Corporate Lawmaking (ECGI Law Working Paper No. 879/2025), argues that the 2024-2025 episode reflects a breakdown in Delaware's traditional consensus-driven lawmaking process, driven by the rise of dual-class controlled companies and structural changes in the Delaware legal market.47 Dorothy S. Lund and Eric L. Talley's 2025 working paper Should Corporate Law Go Private? works through the contractarian limit case — that the rules governing controlling-shareholder transactions, books-and-records procedure, and standards of review could be supplied by firm-level charter and bylaw provisions rather than by any state's code.48 Jens Frankenreiter and Eric Talley’s piece in volume 16 of the Harvard Business Law Review, Sticky Charters?, supplies the empirical complement, documenting that even when Delaware made officer-exculpation provisions available by 2022 amendment to DGCL § 102(b)(7), firms have been slow to adopt them — a finding that bears on whether SB 21's cleansing safe-harbor will, in practice, be invoked by the firms eligible to use it.49 The author's own contribution to this camp, The Texas Two-Step: Rewriting the Rules in the Battle for Corporate Domicile, in the Securities Regulation Law Journal, analyzes the SB 29 and SB 1057 framework as an institutional response that Texas has explicitly designed to address the practitioner concerns Goshen and Stein, Talley/Sanga/Rauterberg, and Kahan-Rock identify.36 Stephen Bainbridge supplies a parallel doctrinal interpretation of the Delaware response: his pre-SB 21 critique in A Course Correction for Controlling Shareholder Transactions argues that Delaware doctrine had moved too far in expanding controller status and entire-fairness exposure, and proposes a narrowing program for conflicted-controller transactions,54 and his subsequent paper Delaware Senate Bill 21: What It Does and What Questions Remain Open treats SB 21 as the statutory response to that doctrinal trajectory — a new controlling-stockholder definition, revised safe-harbor mechanics for conflicted-controller and director/officer transactions, and a narrower books-and-records framework.55
The fiduciary-liability and corporate-personhood camp argues that the Delaware-Exit debate has been conducted in imprecise terms that conflate distinct legal categories. Marc I. Steinberg, Rupert and Lillian Radford Chair at SMU Dedman School of Law, supplies the directly relevant fiduciary-liability contribution in his 2025 Oxford University Press book Corporate Director and Officer Liability — "Discretionaries" Not Fiduciaries, arguing that the practical authority of directors and officers is not well described by fiduciary terminology because corporate-law liability standards are far more forgiving than ordinary fiduciary law: the codified business judgment rule in Texas SB 29 and the cleansing safe-harbor in Delaware SB 21 are best read as candid statutory recognitions of that reality.50 Carliss N. Chatman's 2018 piece in the Nevada Law Journal, The Corporate Personhood Two-Step, supplies the personhood-and-entity-boundaries critique that the event-study and charter-choice literatures do not reach, asking how parent-subsidiary structures, governance norms, and the dual nature of corporate personhood allocate power and accountability across affiliated entities — a lens directly relevant to the Tesla-xAI-SpaceX governance question that motivated the Delaware-Exit episode in the first place.51
