Life as a Public Company

After an IPO a company files annual reports on Form 10-K, quarterly reports on Form 10-Q, and current reports on Form 8-K (often within four business days of a triggering event), with CEO and CFO certifications and internal-control requirements under Sarbanes-Oxley. Regulation FD bars selective disclosure, and insiders who want to trade routinely use Rule 10b5-1 plans, which the SEC tightened in December 2022 with cooling-off periods and new disclosures. In 2026 the SEC proposed, but had not adopted, optional semiannual reporting and a broad overhaul of filer status and offering rules.

The reporting cycle

SEC rules require a reporting company to file annual reports on Form 10-K and quarterly reports on Form 10-Q, and these reports require much of the same information as an offering registration statement ^[1]. The CEO and CFO must certify the financial and certain other information in each 10-K and 10-Q ^[1]. Smaller reporting companies and EGCs may use scaled disclosure in these reports ^[1].

Between periodic reports, the company must file current reports on Form 8-K for specified events, often within four business days ^[1]. Triggering events include entering into or terminating a material definitive agreement, completing an acquisition or disposition of assets, notice of delisting, unregistered equity sales, changes in the certifying accountant, changes in control, director and officer appointments and departures, and charter or bylaw amendments ^[1]. All of these filings go through EDGAR and become publicly available on filing ^[1].

Internal controls under Sarbanes-Oxley

Management of every public company must assess the effectiveness of its internal control over financial reporting ^[6]. The separate auditor attestation under Section 404(b) is phased in: EGCs are not required to provide it ^[5], other newly public companies have up to two years after the IPO before it applies, and smaller reporting companies are exempt ^[6]. For many IPO candidates, building documented controls, a close process that supports quarterly reporting, and a disclosure committee is the longest-lead item in readiness work.

Regulation FD

Regulation FD, effective October 23, 2000, provides that when an issuer or a person acting for it discloses material nonpublic information to securities market professionals or to holders who may well trade on it, the issuer must disclose that information publicly ^[2]. Public disclosure must be simultaneous for intentional disclosures and prompt for non-intentional ones, and it can be made by filing or furnishing a Form 8-K or through another method reasonably designed for broad, non-exclusionary distribution ^[2]. In practice this shapes earnings calls, investor conferences, and one-on-one meetings.

Insider trading and Rule 10b5-1 plans

Rule 10b5-1, also adopted in 2000, provides that a person trades "on the basis of" material nonpublic information when they buy or sell while aware of it, and it sets out affirmative defenses for trades made under arrangements adopted before the person became aware of such information ^[2]. On December 14, 2022, the SEC adopted amendments tightening the affirmative defense ^[3]. Under the amended rule:

• Directors and officers face a cooling-off period of the later of 90 days after plan adoption or modification, or two business days after the issuer discloses results for the quarter in which the plan was adopted, capped at 120 days ^[4].
• Other persons, except issuers, face a 30-day cooling-off period ^[4].
• Directors and officers must certify they are not aware of material nonpublic information and are adopting the plan in good faith ^[3].
• Overlapping plans are restricted, and single-trade plans are limited to one per 12-month period for persons other than issuers ^[3].
• Issuers must disclose insider trading policies, quarterly report plan adoptions and terminations by directors and officers, and disclose option grants made close to the release of material nonpublic information ^[3].
• Form 4 filers must check a box when a reported trade was made under a 10b5-1 plan, and bona fide gifts move to Form 4 ^[3].

2026: proposals, not yet final rules

On May 5, 2026, the SEC proposed amendments that would let public companies choose to file semiannual reports on a new Form 10-S instead of quarterly reports on Form 10-Q ^[7]. A company electing the option would file one semiannual report and one annual report each fiscal year instead of three 10-Qs and one 10-K, with the Form 10-S due 40 or 45 days after the first half, depending on filer status ^[7]. The comment period closed July 6, 2026, and the SEC's rulemaking page, last updated July 31, 2026, still lists the item as a proposed rule ^[8]. Quarterly 10-Q reporting therefore remains the requirement unless and until a final rule is adopted.

On May 19, 2026, the SEC proposed two further rulemakings that Chairman Paul Atkins described as the foundation of his agenda to "Make IPOs Great Again" ^[9]. As proposed, they would raise the large accelerated filer threshold from $700 million to $2 billion, keep a company from becoming a large accelerated filer for at least 60 months after its IPO, exempt all non-accelerated filers from auditor attestation of internal control, broaden shelf eligibility and well-known seasoned issuer flexibilities, allow research coverage of more companies, and preempt state registration for all registered offerings ^[9].
