U.S. Investor Relations in 2026: Disclosure, Trading Hours and AI

Geography: United States
Review period: 11 July–8 October 2026

An investor relations team may have one approved set of facts but several audiences and channels: the filed release, an investor deck, prepared remarks, a live call and a later transcript. Recent U.S. market developments make the handoffs between those channels more consequential. They also call for careful labels. A proposal is not an effective rule; a conditional exemption is not evidence of widespread adoption; a market statistic describes its measured population, not every public company.

This review draws on public material issued during the latest 90 days. Some sources published in that window analyze earlier activity, which is identified below. The practical responses are editorial and workflow inferences from the cited evidence, not claims that every issuer faces the same exposure.

AI: observed call language and a public discussion, not a new issuer mandate

The SEC Investor Advisory Committee discussed AI and the public-market information ecosystem on 10 September. In remarks to the committee, Commissioner Mark Uyeda described possible effects of AI tools on how disclosures are prepared, disseminated and used. He noted increased downloads of SEC structured data, but did not establish that AI caused the increase. One commissioner's remarks do not create a disclosure requirement.

There is a narrower, measurable observation about company language. FactSet reported on 18 September that 331 of 493 calls in its S&P 500 transcript sample mentioned “AI,” or 67%. The calls took place from 15 June through 14 September; some therefore preceded this review's 90-day publication window. The sample concerns an index of U.S.-listed companies and should not be recast as a count of U.S.-domiciled issuers or of IR departments using AI. A mention also says nothing on its own about deployment, returns or communication quality.

If AI is material to a particular issuer's story, IR can ask three source-control questions before an earnings call: Which documented activity is management describing? Which measure, period and limitation support the statement? Does the answer remain consistent between the filed release, deck, script and Q&A? Where AI assists with a summary, a person should compare it with the underlying filing. Those are practical checks for the issuer's own facts, not a market-wide adoption prescription.

Proxy process: SEC proposals require monitoring, not premature implementation

On 16 September, the SEC proposed rescinding Rule 14a-8 and separately proposed proxy-solicitation changes. The announced subjects included annual-report delivery and broker-search timing. The proposals were open for comment at the source date. Their final form and timing remain uncertain in this review; proposed text should not be presented as an operative issuer obligation.

An IR and governance team can record the primary release, map which steps in its shareholder-engagement and proxy timetable might be affected, and assign an owner to check subsequent SEC action. Live proxy decisions should be checked against requirements actually in force by the issuer's responsible functions. This keeps a scenario plan separate from the current operating calendar.

NIRI's October leadership update named proxy advisers, 13-F reform and a possible public-company advisory committee as advocacy topics. The update helps identify questions practitioners are following. It records NIRI's perspective; it neither changes a rule nor measures how all issuers view those questions.

Trading hours: discussion is broad, while August overnight volume was small and concentrated

At a 17 September roundtable, SEC Chairman Paul Atkins asked for issuer input on corporate actions, material-information dissemination and the relationship between expanded trading and EDGAR filing hours. The remarks identify a timing problem to examine. They do not impose a 24-hour issuer disclosure or staffing requirement.

The most relevant observed measure has a defined denominator. A 10 September SEC Trading and Markets staff memorandum found that overnight activity represented 0.9% of NMS share volume on an average August 2026 trade date. On an average day, 4,208 stocks traded overnight. The ten most active names accounted for 43.4% of overnight volume, against 10.3% in regular hours. Overnight average daily volume had risen 359% year over year but fallen 27% month over month. These are one month's descriptive NMS-market observations from SEC staff, not Commission policy, a forecast or evidence that every issuer's shares are actively traded overnight.

That boundary changes the sensible action. Start with the issuer's own trading and announcement pattern. Identify who receives an out-of-hours material-event alert, who verifies the fact, who authorizes communication, and how the approved release, filing and market contacts connect. Rehearse the handoff for a realistic event; scale monitoring to actual exposure. The public data support readiness planning, not a universal call for continuous IR coverage.

Tokenized stock: issued relief is conditional and issuer exposure must be checked

The SEC's 17 September action was a temporary, conditional exemption for qualifying venues that facilitate trading in tokenized NMS stock, accompanied by a request for comment. The SEC described limits on symbols and volume, protection of the same holder rights, trading-halt coordination, and, in specified unaffiliated third-party circumstances, notice to the issuer with an opportunity to object. Unlike the proxy item, relief was issued. Its conditions are important; it does not demonstrate that any named issuer's shares trade on such a venue or establish market-wide uptake.

IR's immediate question is therefore an ownership question, not a promotional claim. If a relevant notice arrives, who routes it to legal, corporate-secretary, transfer-agent and market-operations contacts, and who approves any issuer statement? Public wording should identify what has actually happened to that issuer rather than extrapolate from the existence of the exemption. A NIRI symposium agenda included tokenization and 23/5 trading; agenda topics show professional attention, not realized adoption.

Capital raising and multi-channel reporting: historical counts and one issuer example

The SEC reported on 23 September that its U.S. market data showed 208 IPOs raising more than $137 billion in the first half of 2026, compared with 180 raising more than $27 billion in the first half of 2025. Registered follow-on offerings numbered 557 and raised more than $111 billion, compared with 505 and nearly $84 billion. The release falls inside this review period; the transactions measured do not. Proceeds can be influenced by a few large deals. These figures do not forecast the second half or quantify demand for IR staff.

The issuer-level communication task is easier to see in a separate source. FactSet's 30 September earnings-release exhibit presents GAAP and adjusted measures, a reconciliation and guidance alongside a presentation, investor call and replay, and a transcript channel. This is one U.S. issuer's example, not a representative sample or a required template for non-GAAP presentation. It illustrates why a team should set an approved source for each figure and check later channels for changed definitions or missing qualifications.

Practitioner channels add questions, not population estimates. NIRI said in September that its own IR Update was moving from a quarterly magazine to a continuously updated web publication. That is a completed change to NIRI's publication; it does not prove a change in every IR team's monitoring cadence. A public crisis-response excerpt raises alert ownership, fact verification, speaking authority and cross-function consistency. Only the public excerpt informs this review.

Turn the status labels into an IR change log

For each new item, record its date, primary source, population and status: proposed, issued with conditions, observed in a defined sample, or professional discussion. Add the issuer-specific question, the owner who can check the next update and the point at which an operating procedure should be reconsidered. For a company statement, link the approved figure to each channel that repeats it. For a possible out-of-hours event, test the alert and approval chain before it is needed.

This is a purposive current-change review, not a census of U.S. IR practice. The S&P 500 call sample has its own dates and includes U.S.-listed index constituents without establishing every issuer's domicile. The overnight figures describe NMS trading in August, the offering figures describe first-half issuance, and the earnings exhibit describes one company. Those limits are part of the finding: they make the workflow decisions more precise without making the evidence say more than it can.
