Section 16 Reporting for Equity Awards: 2026 Practitioner Walkthrough

Your CEO just received an RSU grant. Your CFO exercised stock options and elected net settlement. Your head of sales transferred options to a family trust. Three events, three potential Form 4 filings, three two-business-day clocks, and three different ways to get it wrong.

This guide is written for equity plan administrators, general counsel, and SEC reporting managers who need to know exactly what gets reported, on which form, in which table, using which transaction code, and by when. It covers the full equity award lifecycle for domestic issuers and addresses the March 18, 2026 expansion that brought foreign private issuers into the Section 16 regime for the first time.

For the FPI-specific transition story, see our dedicated guide on the foreign private issuer Section 16 exemption. For the full transaction code reference, see our Form 4 transaction codes walkthrough. This article focuses on the equity award lifecycle mechanics that neither of those covers.

Who Is Subject to Section 16 Reporting for Equity Awards?

Section 16(a) of the Securities Exchange Act of 1934 requires every director, officer (as defined in Rule 16a-1(f)), and beneficial owner of more than 10% of a registered class of equity securities to file reports with the SEC disclosing their beneficial ownership and any changes to it. Equity awards, stock options, RSUs, PSUs, SARs, and similar compensatory grants, fall squarely within that disclosure obligation.

The "officer" definition under Rule 16a-1(f) is broader than most companies initially assume. It covers:

• The president
• The principal financial officer
• The principal accounting officer (or controller, if no PAO exists)
• Any vice president in charge of a principal business unit, division, or function (sales, administration, finance)
• Any other officer who performs a policy-making function
• Any person who performs similar policy-making functions

That last catch-all requires a judgment call. A division president with P&L authority almost certainly qualifies. A regional VP who executes strategy but does not set it may not. Get this determination wrong and you either miss required filings or over-designate people who then need to pre-clear every trade.

The 2026 expansion. The National Defense Authorization Act for Fiscal Year 2026, signed December 18, 2025, eliminated the longstanding Section 16(a) exemption for foreign private issuers. Effective March 18, 2026, directors and officers of FPIs whose securities are registered under Section 12(b) or 12(g) now file Forms 3, 4, and 5 on the same timeline as domestic insiders. Critically, the 10% beneficial owner threshold does NOT apply to FPIs, only directors and officers are covered. And Sections 16(b) and 16(c) (short-swing profit recovery and short sale prohibition) remain inapplicable to FPI insiders even after the expansion. Only the reporting obligation under 16(a) changed.

For a full breakdown of the FPI transition mechanics, see the March 18, 2026 Section 16 deadline guide.

Forms 3, 4, and 5: Which Form Applies to Which Equity Award Event?

The three Section 16 forms serve distinct purposes, and equity awards touch all three at different lifecycle stages.

The Form 3 vs Form 4 vs Form 5 comparison guide covers the form-selection logic in detail. What follows here is the equity award lifecycle, stage by stage.

Key takeaway: The Form 4 deadline is two business days from the transaction date, a hard deadline tightened from 10 days by the Sarbanes-Oxley Act of 2002. There is no grace period. A filing on the third business day is a late filing, disclosed in the proxy statement under Item 405 of Regulation S-K.

The Equity Award Lifecycle: Stage-by-Stage Reporting Guide

Stage 1: Grant

Most compensatory equity award grants are reportable on Form 4 within two business days of the grant date, using transaction code "A" (grant, award, or other acquisition). The grant is reported in Table II of Form 4 as a derivative security, the award itself (the option, RSU, or PSU) is the derivative, and the underlying common stock is what it converts into upon exercise or settlement.

For stock options, Table II captures the number of shares subject to the option, the exercise price, the expiration date, and the date exercisable. For RSUs, Table II captures the number of units granted and the conversion ratio (typically 1:1 into common stock).

The Rule 16b-3 exemption is critical here. Rule 16b-3 exempts transactions between an issuer and its officers or directors from Section 16(b) short-swing profit liability, provided the transaction is approved by the board, a committee of non-employee directors, or by shareholder vote. Most compensatory equity grants satisfy this requirement because they are approved by the compensation committee. The grant is still reportable on Form 4; Rule 16b-3 just means the insider cannot be sued for short-swing profits on it.

For FPI insiders, Rule 16b-3 applicability requires careful analysis. Since Section 16(b) does not apply to FPI insiders at all under the NDAA expansion, the exemption is technically moot, but FPIs should still confirm this with counsel, as the SEC's implementing regulations may address it.

Stage 2: Vesting

Vesting of an RSU or restricted stock award is a reportable event when it results in a change in beneficial ownership. For restricted stock (shares already issued but subject to forfeiture), vesting itself typically does not require a new Form 4 because the shares were already reported at grant. For RSUs (which are promises to deliver shares), the analysis depends on when delivery occurs.

If the RSU vests and shares are delivered on the same date, there is one reportable event: the acquisition of common stock (Table I, code "M" for conversion of a derivative security). If vesting and delivery are on different dates, for example, vesting occurs but delivery is deferred, the reporting timing follows the delivery date, not the vesting date.

This is where many teams miss filings. If your equity plan has a deferred delivery feature, the two-business-day clock starts on the delivery date, not the vesting date. Map this in your equity plan calendar before the fiscal year begins.

Stage 3: Net Settlement (Tax Withholding)

Net settlement, where the company withholds shares to cover the insider's tax obligation upon RSU vesting, is one of the most commonly misreported equity award events. It generates two entries on the same Form 4:

1. Table II, code "M": The conversion of the RSU (derivative security) into the gross number of shares of common stock. This is an acquisition.
2. Table I, code "F": The shares withheld by the company to cover taxes. Code "F" specifically covers "payment of exercise price or tax liability by delivering or withholding securities incident to the receipt, exercise or vesting of a security issued in accordance with Rule 16b-3." This is a disposition back to the issuer.

The net result is that the insider reports acquiring, say, 1,000 shares (code M) and simultaneously disposing of 300 shares for tax withholding (code F), ending up with 700 shares. Both entries go on the same Form 4, filed within two business days of the vesting/delivery date.

Using code "D" (disposition to the issuer) instead of code "F" for the tax withholding is a common error that requires an amendment. Code "D" is for voluntary dispositions back to the issuer; code "F" is specifically for tax withholding and exercise price payments. Get this wrong once and you have established a precedent that will be wrong on every future filing of the same type.

As Simpson Thacher notes, "the initial reporting approach for an equity award transaction type often serves as the template for future transactions of the same type." Establish the correct approach from the first filing.

Stage 4: Stock Option Exercise

A stock option exercise generates a dual-entry Form 4: the exercise of the derivative (Table II, code "M") and the acquisition of the underlying common stock (Table I, code "M"). The two-business-day clock starts on the exercise date.

For a cashless exercise (sell-to-cover), there is a third entry: the open-market sale of shares to fund the exercise price (Table I, code "S"). This sale is also reportable and also starts its own two-business-day clock, though in practice it occurs on the same date as the exercise, so a single Form 4 captures all three events.

For a same-day sale (exercise and immediate sale of all shares), the Form 4 reports the exercise (Table II, code "M"), the acquisition of shares (Table I, code "M"), and the sale (Table I, code "S"). The insider ends up with no shares but must still report the full chain.

For the detailed derivative security mechanics, see our Section 16 reporting for derivative securities walkthrough.

Stage 5: Performance-Based Awards (PSUs)

PSU reporting is the most interpretively complex area of Section 16 equity award compliance, and the SEC has not issued definitive guidance on timing.

The general rule, based on SEC staff guidance and practitioner consensus, is:

• If vesting is contingent on performance conditions other than (or in addition to) stock price targets, the award is not considered "granted" for Section 16 purposes until the performance conditions are satisfied. The Form 4 is filed when the compensation committee certifies that the performance goal has been achieved, not at the original grant date.
• If vesting is contingent solely on stock price targets (absolute stock price, not relative TSR), the award is reported at grant as a derivative security acquisition (code "A").
• Relative TSR is treated as a non-stock-price performance condition for Section 16 purposes, even though FASB treats it equivalently to a stock price target for accounting purposes. Most relative TSR awards are therefore reported at certification, not at grant.

The practical consequence: if a PSU is granted in January 2026 with a three-year revenue target, and the compensation committee certifies achievement in February 2029, the Form 4 is due within two business days of the February 2029 certification date. If the target is never achieved and the award is forfeited entirely, no Form 4 is ever required.

Some companies voluntarily report PSUs at grant (using the target number of shares). This is permissible but creates complications: if the award ultimately pays out above target, the additional shares must be reported at certification. And it is unclear whether voluntary early reporting relieves the obligation to report again at certification. The cleaner approach for most companies is to wait for certification.

Key takeaway: For PSUs with non-stock-price performance conditions, the Form 4 clock starts on the compensation committee certification date, not the grant date. Build this into your equity plan calendar and your committee meeting schedule.

Stage 6: Dividend Equivalent Rights (DERs)

Whether dividend equivalent rights on RSUs trigger a Form 4 depends on the structure of the issuer's dividend program. If the issuer operates a qualifying dividend reinvestment plan (DRIP) that satisfies Rule 16a-11, acquisitions under the DRIP are exempt from Section 16(b) and may be reported on Form 4 or Form 5. If the DER credits additional RSU units (rather than cash), that credit may itself be a reportable acquisition of a derivative security.

Review your equity plan's DER provisions before the first dividend record date after an insider receives an award. The timing of the Form 4 obligation varies depending on whether the DER is settled in cash, in additional units, or in shares, and whether a DRIP exemption applies.

Stage 7: Transfers for Estate Planning

Transferring equity awards to a family member or trust for tax or estate planning purposes is itself a reportable Section 16 transaction. The transfer is reported as a disposition by the insider (Table II, code "D" or another applicable code depending on the transfer structure) and the transferee's subsequent holdings may need to be tracked as indirect ownership.

Whether the transferee's transactions in those awards then require Form 4 filings by the original insider depends on whether the insider retains a pecuniary interest in the transferred securities. If the insider transferred options to an irrevocable trust for the benefit of children and retains no economic interest, the analysis may differ from a revocable trust where the insider remains the economic beneficiary.

As Simpson Thacher advises, issuers should establish pre-clearance procedures for equity award transfers and educate insiders to notify the company before executing them, because a missed filing on a transfer is just as consequential as a missed filing on a market sale.

Table I vs. Table II: How Equity Awards Move Between Tables

This is the structural detail that most Section 16 guides skip entirely.

Form 4 has two tables, and equity awards move between them across their lifecycle:

• Table II (Derivative Securities): Where equity awards live from grant until they convert into common stock. Options, RSUs, PSUs, and SARs are all reported in Table II at grant and remain there until exercise or settlement. Table II captures the derivative security itself (the award), the underlying security, the exercise price (if any), and the expiration or settlement date.
• Table I (Non-Derivative Securities): Where common stock lives. When an RSU vests and shares are delivered, or when an option is exercised and shares are acquired, those shares move into Table I. The conversion event (code "M") appears in both tables simultaneously on the same Form 4.

A practical example: your CFO holds 5,000 RSUs granted in 2024 (reported in Table II at grant). In March 2026, 1,250 RSUs vest and 375 shares are withheld for taxes. The Form 4 reports:

• Table II: Disposition of 1,250 RSUs (code "M"), the derivative is extinguished
• Table I: Acquisition of 1,250 shares of common stock (code "M"), the underlying shares are received
• Table I: Disposition of 375 shares withheld for taxes (code "F"), the tax withholding

Net result in Table I: +875 shares. All three lines go on one Form 4, filed within two business days of the vesting date.

Transaction Code Quick Reference for Equity Awards

For the full transaction code reference with edge cases, see our Form 4 transaction codes practitioner walkthrough.

The Rule 16b-3 Exemption: What Board Approval Actually Requires

Rule 16b-3 exempts compensatory equity award transactions from Section 16(b) short-swing profit liability, but only if the transaction meets one of three approval conditions:

1. The transaction is approved by the full board of directors
2. The transaction is approved by a committee of two or more non-employee directors
3. The transaction is approved by shareholders

For most companies, the compensation committee satisfies condition 2. Each committee member must qualify as a "non-employee director" under Rule 16b-3(b)(3), meaning they cannot receive compensation from the company other than as a director, and cannot be an officer or former officer of the company.

The exemption covers grants, exercises, vesting events, and net settlement transactions. It does not cover open-market purchases or sales by the insider, even if the insider is using proceeds from an equity award exercise.

This distinction matters for short-swing profit analysis. If a CFO exercises options (exempt under Rule 16b-3) and then sells shares in the open market within six months of a prior open-market purchase, the sale and the purchase can be matched for Section 16(b) purposes. The option exercise itself is not matchable, but the resulting shares are. For the calculation mechanics, see our short-swing profit rule calculation guide.

Indirect Holdings: Trusts, 401(k) Plans, and Family Entities

Shares held through trusts, employer-sponsored retirement plans, and family entities must be disclosed as "indirect" holdings on Form 3 and tracked for Form 4 purposes. Whether a transaction in those indirectly held shares triggers a Form 4 depends on whether the insider has a pecuniary interest in the transaction.

Common situations:

• 401(k) plan: Shares acquired through an employer-sponsored plan are typically exempt from Section 16(b) under Rule 16b-3, but must still be disclosed as indirect holdings. Routine plan contributions that result in share acquisitions may be reportable on Form 4 or deferred to Form 5 depending on the plan's structure.
• Revocable trust: If the insider is both the trustee and the sole beneficiary, shares in the trust are treated as directly owned. Transactions are reportable on Form 4.
• Irrevocable trust for family members: If the insider retains no pecuniary interest, the shares may not be attributable to the insider. Legal analysis required.
• Family limited partnership: If the insider is the general partner with investment control, the partnership's shares are attributed to the insider. Transactions by the partnership trigger Form 4 obligations.

As Simpson Thacher notes, "whether the acquisition or disposition of these shares by a Section 16 filer requires a Section 16 filing will depend on the terms of such acquisition or disposition", making advance review of any trust or plan transaction essential.

FPI-Specific Compliance Steps for Equity Award Reporting

For FPIs that have never filed Section 16 reports, the equity award lifecycle mechanics above now apply in full. The practical setup steps, in sequence:

1. Identify all Section 16 officers under Rule 16a-1(f). Note that individuals identified as executive officers for Dodd-Frank clawback purposes (Rule 10D-1) use the same definition, but FPIs that applied that definition expansively should revisit the list. Some people on the clawback list may not perform a policy-making function sufficient to qualify as Section 16 officers.
2. Prepare an equity holdings inventory. For each director and officer, document: award type, grant date, vesting schedule (including performance criteria), exercise price, expiration date, and whether holdings are direct or indirect. This is the foundation for the initial Form 3.
3. Obtain EDGAR filing credentials. Each reporting person needs an individual CIK number and EDGAR access credentials. FPI insiders who have never filed with the SEC must submit a notarized Form ID. This process can take several weeks, do not leave it to the week before a filing deadline.
4. Execute powers of attorney. Dorsey recommends that FPIs "have powers of attorney executed that permit the issuers to make the filings on the insider's behalf." This company-assisted filing model is standard for domestic issuers and is strongly recommended for FPIs.
5. Establish reporting principles before the first filing. Decide how you will report each equity award transaction type, which table, which code, what footnote language, before you file the first Form 4. Those decisions become the template for every future filing of the same type.
6. Set up the website posting process. FPIs must post Section 16 reports on their corporate website no later than the end of the business day following the SEC filing. This is the same requirement that applies to domestic issuers.
7. Update the insider trading policy. The company's blackout periods, pre-clearance requirements, and Rule 10b5-1 plan procedures all interact with Section 16 reporting. Equity award exercises and vesting events frequently occur near blackout periods, confirm that your policy addresses how these events are handled. See our insider trading blackout period policy guide for the framework.

On the open question of SEC exemptions: the NDAA allows the SEC to exempt FPI insiders subject to "substantially similar" foreign requirements, but as of the date of this article, the SEC has indicated that such exemptions are outside the scope of the initial rulemaking and may be addressed separately. Do not assume an exemption will apply.

What Happens If You Miss a Filing

Late Section 16 filings are not a private matter. Under Item 405 of Regulation S-K, the company must disclose in its annual proxy statement (or Form 10-K for smaller reporting companies) the name of any reporting person who failed to file a required Section 16 report on time during the prior fiscal year. One late Form 4 generates a proxy disclosure. A pattern of late filings signals a systemic control failure.

Beyond proxy disclosure:

• The SEC can bring enforcement actions for Section 16(a) violations.
• Under Section 16(b), the issuer itself can be required to disgorge short-swing profits if it fails to do so voluntarily. Shareholder plaintiffs can bring derivative suits on the company's behalf, and Section 16(b) is a strict liability regime. Intent is irrelevant.
• For FPIs, late filings also create reputational risk with the US investor community that has not previously had visibility into insider transactions.

For the full enforcement picture, see our SEC late filing penalties Section 16 guide.

FAQ: Section 16 Reporting for Equity Awards

Who is subject to Section 16 reporting? Directors, officers as defined under Rule 16a-1(f), and beneficial owners of more than 10% of a registered class of equity securities of a domestic issuer. For FPIs, only directors and officers are covered under the March 2026 expansion, the 10% threshold does not apply to FPIs.

Is the grant of an equity award always reportable on Form 4? For most awards, yes, the grant is reported within two business days using code "A." The main exception is PSUs with non-stock-price performance conditions, which are not reportable until the compensation committee certifies that the performance conditions have been met.

Are compensatory equity award grants exempt from Section 16(b) short-swing profit rules? Yes, if the transaction is approved by the board, a committee of non-employee directors, or shareholders under Rule 16b-3. The grant is still reportable on Form 4; Rule 16b-3 only exempts it from short-swing profit liability, not from the reporting obligation.

What are the Section 16 exemptions for equity awards? Rule 16b-3 is the primary exemption for compensatory transactions. It covers grants, exercises, vesting events, and net settlement transactions that are board- or committee-approved. Certain small acquisitions (under Rule 16a-6) may be deferred to Form 5. Gifts were previously deferrable to Form 5 but must now be reported on Form 4 within two business days following SEC rule amendments effective February 2023.

Can an insider cash out equity awards? Yes. A cashless exercise of stock options (sell-to-cover) and a same-day sale are both permissible and reportable. The exercise is reported in Table II (code "M"), the share acquisition in Table I (code "M"), and the sale in Table I (code "S"). Net settlement (tax withholding) is a related mechanism where shares are withheld rather than sold in the market, reported with code "F."

Do FPI insiders need to report equity awards they received before March 18, 2026? Yes. The initial Form 3 (due March 18, 2026 for insiders who were directors or officers as of that date) must report all current equity holdings, including awards granted before the effective date. Going forward, any transaction in those pre-existing awards is reportable on Form 4 within two business days.

The forms are short. The compliance is not. Building the right workflow before the first filing is the only way to avoid the errors that compound across every subsequent transaction of the same type.
