SEC Semiannual Reporting Proposal: What Public Companies Should Know About Form 10-S

The U.S. Securities and Exchange Commission’s SEC semiannual reporting proposal could significantly change how public companies meet their periodic reporting obligations. Under the proposal, public companies currently required to file quarterly reports on Form 10-Q would have the option to file a new semiannual report on Form 10-S instead.

The SEC issued the proposal on May 5, 2026, and published it in the Federal Register on May 7, 2026. Public comments are due by July 6, 2026. If adopted, the amendments would give issuers more flexibility in determining how frequently they report interim financial information while continuing to meet disclosure obligations under federal securities laws.

For companies that rely on professional EDGAR filing services, this proposal represents an important regulatory development that could influence reporting calendars, compliance workflows, disclosure controls, and filing strategies. As SEC reporting requirements continue to evolve, businesses should closely monitor the SEC’s rulemaking activity and evaluate how potential changes may affect their operations.

Understanding the Proposed Rule Changes

Currently, public companies subject to Exchange Act Sections 13(a) or 15(d) generally must file three quarterly reports on Form 10-Q and one annual report on Form 10-K each fiscal year. The SEC’s proposal would create a new reporting option under Form 10-S, allowing eligible companies to submit a single semiannual report and a single annual report instead.

The proposal does not eliminate disclosure requirements or remove investor protections. Rather, it introduces optional semiannual reporting by allowing companies to choose the interim reporting framework that best aligns with their business needs, shareholder expectations, and public company reporting obligations.

According to SEC Chairman Paul S. Atkins, the proposal is intended to give companies and investors more flexibility to determine the reporting frequency that serves their interests while preserving the core objective of providing material information to the marketplace.

Companies would generally make the semiannual reporting election by checking a box on the cover page of Form 10-K or certain registration statements. The election would be made annually and generally could not be changed during the fiscal year.

Who Would Be Eligible to Use Form 10-S?

The proposed Form 10-S framework would generally apply to domestic Exchange Act reporting companies that are currently required to file quarterly reports on Form 10-Q. This may include large accelerated filers, accelerated filers, non-accelerated filers, smaller reporting companies, and certain business development companies where applicable.

Foreign private issuers would generally not be directly affected unless they voluntarily use domestic reporting forms or otherwise become subject to domestic reporting requirements.

For companies already navigating SEC compliance, the key point is that the proposal would offer a choice. Some issuers may continue quarterly reporting, while others may determine that a semiannual reporting structure better fits their operations, investor base, and long-term strategy.

How Form 10-S Would Work

Under the proposed framework, companies electing semiannual reporting would file a new Form 10-S covering the first six months of their fiscal year. Proposed Form 10-S would require many of the same narrative disclosures and financial information currently provided in Form 10-Q, adjusted to cover a six-month reporting period. Companies should not view Form 10-S as a reduced-disclosure report.

Form 10-S may include Management’s Discussion and Analysis, interim financial statements, legal proceedings, risk factor updates where applicable, market risk disclosures, controls and procedures, CEO and CFO certifications, and Inline XBRL tagging requirements.

Financial statements included in Form 10-S would generally need to be reviewed by an independent public accountant and prepared in accordance with applicable accounting standards. Companies would also need to maintain appropriate disclosure controls and internal reporting processes.

The proposed filing deadlines would vary based on filer status:

Companies would continue filing annual reports on Form 10-K and remain subject to other SEC disclosure obligations, including Form 8-K reporting requirements for material events. For issuers already working with SEC filing services providers, the introduction of Form 10-S could simplify certain reporting schedules while maintaining compliance with federal securities laws.

What Would Still Need to Be Filed?

The SEC semiannual reporting proposal primarily affects interim reporting frequency. It does not eliminate the broader public company filing framework.

Companies that elect semiannual reporting would still need to comply with applicable requirements for annual reports on Form 10-K, current reports on Form 8-K, registration statements, proxy statements, insider reporting obligations, beneficial ownership filings, XBRL and Inline XBRL tagging, disclosure controls, and CEO and CFO certifications.

This distinction is important. Even if a company elects to replace Form 10-Q filings with Form 10-S, it would still need to maintain a strong SEC compliance program and remain prepared to disclose material events on a timely basis.

Why the SEC Is Considering Semiannual Reporting

The SEC’s proposal reflects ongoing discussions regarding the balance between investor transparency and regulatory burden. Preparing quarterly reports often requires substantial resources from finance teams, legal departments, auditors, disclosure committees, and external advisors.

Many public companies have argued that quarterly reporting contributes to increased compliance costs and may encourage short-term business decision-making. By offering an optional semiannual reporting framework, the SEC aims to provide companies with additional flexibility while maintaining meaningful disclosure standards.

Companies considering optional semiannual reporting would also need to weigh investor expectations, potential effects on analyst coverage, market transparency, liquidity, and cost of capital. For some companies, investors may still expect quarterly earnings releases or other interim updates even if Form 10-Q filings are no longer required.

Impact on Compliance and Reporting Operations

If the proposal becomes final, public companies will likely need to reassess internal reporting procedures and compliance workflows. Reporting calendars, disclosure controls, and financial reporting processes may require adjustments depending on whether a company elects the semiannual reporting option.

Organizations utilizing EDGAR filing services may also need to coordinate with their filing providers to update schedules, filing procedures, document preparation timelines, and Inline XBRL processes. Although the number of interim reports could decrease, the importance of accurate and timely disclosures will remain unchanged.

Companies may also need to consider how semiannual reporting would affect disclosure committee meetings, sub-certification processes, investor relations practices, Regulation FD compliance, insider trading policies, trading windows, blackout periods, earnings release procedures, and auditor review timelines.

Financial Reporting and Inline XBRL Considerations

The SEC’s proposal also includes amendments to Regulation S-X, which governs financial statement requirements for periodic reports, registration statements, and proxy statements. The Commission intends to modify Regulation S-X to reflect the new semiannual reporting framework while simplifying certain interim financial reporting requirements.

Financial reporting technology will continue to play an important role in compliance. Companies that rely on XBRL filing processes should pay close attention to any updates affecting financial statement presentation, tagging, and disclosure requirements. Because the proposed Form 10-S would still include interim financial statements, companies should not assume that semiannual reporting eliminates the need for rigorous financial reporting controls.

What This Means for EDGAR Filers

The proposal arrives at a time when the SEC is actively modernizing its filing infrastructure and compliance processes. Public companies are already preparing for major regulatory initiatives, including EDGAR Next, which introduces enhanced account management and filing authorization procedures.

If the proposal is adopted, companies may need to update their EDGAR filing calendar to account for a new Form 10-S filing deadline. Public companies should also coordinate with their EDGAR filing services provider to confirm document preparation timelines, filing codes, Inline XBRL tagging processes, and EDGAR Next account authorization procedures.

Conclusion

The SEC’s proposal to permit optional semiannual reporting represents a potentially significant shift in the public company reporting landscape. By allowing issuers to choose between quarterly and semiannual interim reporting, the Commission seeks to provide greater flexibility while preserving investor protections and disclosure transparency.

Although the proposal remains subject to public comment and final SEC approval, companies should begin evaluating how the changes could impact reporting processes, compliance programs, disclosure obligations, investor communications, and filing calendars.
