Trend of US States Issuing Proxy Voting Legislation Now Includes Arizona

There has recently been a surge of US states proposing proxy voting bills, which would implement a sole-economic-interest standard for proxy voting by fiduciaries of public pension benefit plans and enact new regulatory requirements on proxy advisory firms that issue voting recommendations. Arizona joins this trend with its Senate Bill 1503.

Over the past month, a flurry of US states have introduced Proxy Advisor Transparency Act–style legislation regulating proxy advisory firms. These include Tennessee HB 2476, Mississippi SB 2676, Indiana HB 1273, and similar new bills in Arizona, Iowa, Nebraska, South Carolina, West Virginia, and Wisconsin. Wyoming’s comparable bill failed to advance.

These bills reflect a broader national trend toward heightened scrutiny of proxy voting practices, fiduciary duties, and shareholder engagement. They follow a Texas law (SB 2337), which was passed this summer and imposes disclosure and economic-interest requirements on proxy advisory firms when their recommendations are not based solely on shareholders’ financial interests, and a recent executive order has directed federal agencies to review the regulation of proxy advisors and environmental, social, or governance (ESG) related voting practices within the federal fiduciary framework.

This LawFlash focuses on one of these new bills, Arizona Senate Bill 1503 (SB 1503), to illustrate the type of legislation at issue. If passed, this role would reshape the legal landscape for proxy voting by public pension fiduciaries and their engagement with proxy advisory firms. The bill—introduced on January 29, 2026, sponsored by Senators David Gowan and Javan Mesnard and Representative Justin Olson—has advanced out of committee.

Senator Gowan informed the committee that SB 1503 mirrors recent federal action aimed at refocusing fiduciary decision-making on economic return and limiting the influence of ESG and diversity, equity, and inclusion (DEI) considerations in proxy voting.

SUMMARY OF SB 1503

At its core, SB 1503 would codify a sole-economic-interest standard for proxy voting by fiduciaries of public pension benefit plans and impose new regulatory duties on proxy advisory firms that provide voting recommendations to those fiduciaries.

Under the bill as drafted, fiduciaries would be required to vote all shares held on behalf of pension plans for the exclusive benefit of plan participants and beneficiaries in a manner that maximizes risk-adjusted returns and prohibits votes that subordinate financial returns to ESG goals or other non-pecuniary objectives unless supported by documented economic analysis.

It would also require fiduciaries to document and report votes that diverge from issuer board recommendations to back-test economic analyses periodically and to submit certified reports to the state treasurer.

If passed, SB 1503 could have implications for a variety of stakeholders, including the below.

Implications for Fiduciary Duties & Proxy Voting

Under current law, Arizona public pension fiduciaries owe traditional fiduciary duties—including duties of loyalty and prudence—to plan participants and beneficiaries. Separate rules generally govern how shareholders may vote proxies under state corporate law.

SB 1503 would introduce a statutory framework that

• requires fiduciaries to vote proxies solely for economic benefit, with a rebuttable presumption that following an issuer board’s recommendation (where the board has a majority of independent directors) satisfies the standard. The same presumption may be afforded if the vote is inconsistent with the board but supported by an economic analysis.
• prohibits voting that subordinates economic interests to non-economic goals, such as ESG or ideological objectives, unless justified by documented economic analysis.
• mandates annual reporting of votes that diverge from issuer board recommendations and the underlying economic analyses to the state treasurer, along with periodic back-testing of analytical models.
• imposes regulatory duties on proxy advisory firms, requiring them to base any recommendations on the “sole economic interest” standard and disclose inconsistencies with board recommendations alongside documented economic analysis.
• creates a consumer right to disclosure, enabling individuals with a financial interest in a security to request the documented economic analysis justifying particular voting decisions.

Implications for Institutional Investors

For institutional investors, SB 1503 could create a number of implications:

• Emphasis on Economic Focus: By centering economic analysis as the basis for proxy decisions, the bill attempts to shift stewardship activity away from broader stakeholder considerations toward a narrowly defined economic focus. This mirrors recent federal debates about the appropriate role of ESG considerations in fiduciary decision-making, particularly within Employee Retirement Income Security Act (ERISA) plans and investment manager standards (e.g., US Securities Exchange Commission, US Department of Labor dialogues).
• Operational and Compliance Burdens: Because the bill would require documented economic analyses and enhanced reporting for any vote that diverges from an issuer board’s recommendation, public pension systems and asset managers may face substantial administrative costs and potential litigation risk. In committee testimony, retirement system representatives reportedly expressed concerns about high volumes of required analyses given the large number of proxy votes cast annually.
  
  The reporting and back-testing requirements may also expose fiduciaries to retrospective second-guessing of economic assumptions, particularly in volatile markets where governance proposals relate to long-term strategic risks.
  
  Institutional investors managing multi-state public assets may face operational fragmentation if similar but not identical statutes proliferate. Managers could be required to create state-specific proxy voting policies, voting rationales, and documentation processes, increasing compliance complexity and cost.

CONTEXTUALIZING SB 1503

Arizona’s proposal does not arise in isolation. Rather, it reflects a broader, multi-level regulatory movement in which both federal and state policymakers are reassessing the role of proxy voting, fiduciary discretion, and the influence of ESG and DEI considerations in capital markets. While the mechanisms differ across jurisdictions, a common theme has emerged: renewed emphasis on economic return as the touchstone of fiduciary conduct and heightened scrutiny of proxy advisory firms and stewardship practices.

At the federal level, proxy voting and fiduciary duties remain subject to concurrent regulatory and oversight activity across agencies that influence how asset managers and investment advisers approach proxy stewardship.

US Executive Order Targets Proxy Advisors and ESG-Related Voting Practices

An executive action has directed agencies to review the regulatory framework governing proxy advisors, assess whether additional registration or transparency requirements are warranted, and evaluate the use of proxy advice that incorporates ESG or DEI considerations.

Proxy Firms Announce Substantive Changes to Voting Policies

The executive order follows recent announcements by certain proxy advisors regarding significant changes to their voting policies. In October 2025, a major proxy advisor announced that beginning in 2027, it will no longer publish a single set of “benchmark” voting policies and will instead offer customized voting policies on a client-by-client basis. While the new policies remain under development, it stated that the goal is to remove the “perception of influence and [transform] proxy voting into a more strategic and client-driven experience.”

Similarly, in updated guidelines published in November 2025, another major proxy advisor announced that beginning in February 2026, it will move away from blanket ESG voting policies, including default support for shareholder proposals requesting climate-and diversity-related disclosures. Instead, it will assess disclosure requests—covering climate risk, emissions, workforce diversity, and related topics—on a case-by-case basis. The advisor’s leadership cited declining shareholder support for ESG proposals, regulatory developments, and improvements in company disclosure practices as reasons for the change.

Congress’s Efforts to Amend ERISA to Limit ESG Investing

On October 31, 2025, Republican Senators Bill Cassidy (R-La.) and Jim Banks (R-Ind.) introduced two bills addressing fiduciary duties and investment disclosures under ERISA. The Restoring Integrity in Fiduciary Duty Act (S.3086), introduced by Senator Cassidy, would require 401(k) plans and pension funds to consider only pecuniary factors when making investment decisions. The proposal builds on similar legislation (H.R. 2988) advanced by a House committee in June 2025.

Meanwhile, the Providing Complete Information to Retirement Investors Act (S.3083), introduced by Senator Banks, would require employer-sponsored retirement plans to disclose specified information to employees, distinguishing fiduciary-managed investments from participant-directed investments.

On January 15, 2026, the House of Representatives passed HR 2988, the Protecting Prudent Investment of Retirement Savings Act, by a narrow 213–205 vote. The bill, sponsored by Representative Rick W. Allen (R-Ga.), would codify a “pecuniary-only” investment standard for ERISA retirement plan fiduciaries, effectively requiring plan sponsors and advisers to prioritize financial returns and economic factors over ESG considerations when making investment decisions on behalf of participants and beneficiaries.

Under the legislation, fiduciaries must base decisions on factors that are expected to have a material effect on risk or return consistent with the plan’s objectives and may consider non-pecuniary factors only where it can be demonstrated that alternatives are indistinguishable based on pecuniary factors alone. HR 2988 would also largely supersede the Biden-era DOL guidance that permitted consideration of ESG factors in retirement investing and aims to reinforce ERISA’s loyalty and prudence requirements for plan fiduciaries. The bill moved to the US Senate for further consideration.

In addition to federal trends, SB 1503’s proposal follows other states. Several states have adopted or proposed similar measures, including the following:

• Texas (SB 2337, 2025): Requires proxy advisory firms to disclose when recommendations are based on non-financial factors and has prompted constitutional litigation challenges from proxy advisory firms
• Utah (2023 law): Requires public entities to vote proxies to maximize risk-adjusted returns for beneficiaries
• New Hampshire (proposed legislation): Would prioritize objective financial factors in retirement system proxy voting and investment decisions

Arizona’s approach is distinctive in combining fiduciary voting mandates, proxy advisor regulation, reporting obligations, and a private right of disclosure in a single statutory framework.

LOOKING AHEAD

SB 1503 has advanced out of committee and awaits further consideration by the full Senate. If passed, it would proceed to the House for consideration and, if approved, to the governor for signature or veto. Amendments remain possible during floor debate, particularly concerning enforcement scope, reporting timelines, and proxy advisor obligations.

If passed, key issues that may need to be explored include the below:

• How “sole economic interest” will be operationalized in practice, especially where proxy proposals involve long-term governance risks—such as climate transition planning, cybersecurity oversight, or executive compensation design—that may not lend themselves to immediate quantitative measurement
• Whether the statutory presumption favoring board recommendations will meaningfully reduce independent stewardship or instead increase formalistic economic documentation
• The interplay between state requirements and federal fiduciary standards, particularly for public pension funds interacting with ERISA-governed managers or operating across multiple jurisdictions
• Potential constitutional challenges, including First Amendment arguments from proxy advisory firms or federal preemption arguments related to securities regulation
• Whether similar legislation in other states will create a patchwork compliance regime for national asset managers

As SB 1503 progresses through the legislature, stakeholders—including pension systems, asset managers, proxy advisors, and institutional investors—will need to assess compliance risks and governance impacts.

Given the rising political and regulatory focus on proxy voting structures nationwide, Arizona’s legislation may become an influential case study in how states attempt to govern fiduciary conduct and shareholder engagement beyond traditional corporate law frameworks—and whether such prescriptive standards reshape the balance between economic analysis, stewardship discretion, and shareholder democracy.
