GRATs on Form 4: Estate Planning That Looks Like Selling

You are scanning an insider's Form 4 and you see a line that says shares were moved into something called a "GRAT." The transaction shows a large number of shares leaving a direct holding. It looks, at a glance, like the executive is offloading stock. In almost every case, it is not. A GRAT transfer is an estate-planning move, and reading it as bearish selling is one of the easier mistakes to make with insider filings.

This guide explains what a grantor retained annuity trust is, why insiders use them, and how to tell a GRAT transfer apart from a genuine open-market sale when you are reading a Form 4 on a page like an insider's profile.

What a GRAT Actually Is

A grantor retained annuity trust (GRAT) is a legal structure wealthy individuals use to pass assets to heirs while minimizing gift and estate taxes. The person who sets it up — the grantor — puts assets like company stock into the trust and, in return, receives a fixed annuity payment back over a set number of years. When the trust term ends, any appreciation above a baseline rate passes to the beneficiaries (usually children) outside of the grantor's taxable estate.

For a corporate insider whose net worth is concentrated in company stock, a GRAT is a standard wealth-transfer tool. Moving shares into a GRAT does not put those shares on the open market — it relocates them from one ownership form to another within the insider's family planning structure.

Why It Shows Up on a Form 4

Insiders — officers, directors, and 10% owners — must report changes in their beneficial ownership of company stock on Form 4. That includes not just buying and selling, but also transfers between the various entities through which they hold shares: family trusts, LLCs, foundations, and GRATs. So when an insider funds a GRAT with stock, the transfer appears on a Form 4 as a disposition from one holding and an acquisition in another.

The key tell is the transaction code and the footnotes. GRAT transfers typically carry a "J" code (other acquisition or disposition) rather than an "S" (open-market sale), and the footnotes will explicitly describe the move — for example, "represents shares contributed to the grantor retained annuity trust of the reporting person." There is no sale price, because nothing was sold.

A Real Example

Consider a recent filing from Kenneth Duda, the president and CTO of Arista Networks (ANET). In May 2026, one of his Form 4 filings documented the transfer of 200,000 shares into grantor retained annuity trusts — 100,000 into his own GRAT and 100,000 into a GRAT for his spouse. The shares moved from a family trust into the annuity trusts; none were sold on the market. A reader who saw only the share count leaving the family trust might assume the CTO was reducing his stake, when in reality he was passing potential appreciation to his heirs in a tax-efficient way.

Contrast that with the same insider's exercise-and-sell activity, where options are exercised and shares are genuinely sold into the market at a stated price under a trading plan. Those are real sales; the GRAT transfer is not. The two coexist in the same insider's filings, which is exactly why reading the codes and footnotes matters.

How to Tell a GRAT Transfer From a Real Sale

When you encounter a large share movement on a Form 4, run through this checklist before concluding anything about sentiment:

• Check the transaction code. An "S" is an open-market sale. A "J" (other) or a transfer-type code, paired with a GRAT footnote, is estate planning.
• Look for a price. A genuine sale has a price per share. A GRAT contribution has no sale price because no money changed hands in the market.
• Read the footnotes. Form 4 footnotes spell out the nature of the transaction. Words like "grantor retained annuity trust," "contributed to," "transfer," and "no consideration" all point to estate planning, not selling.
• Track total beneficial ownership. After a GRAT transfer, the insider's overall beneficial ownership often barely changes, because the shares simply moved to a related entity the insider still influences.

Why This Matters for Investors

The whole point of distinguishing a GRAT transfer from a sale is that they carry opposite signals. A genuine, unplanned open-market sale by an insider can be a meaningful data point. A GRAT contribution is a sign of an insider doing routine wealth and estate planning — often a sign of confidence that the stock will keep appreciating, since GRATs are most effective precisely when the contributed assets grow. Misreading one as the other can lead you to exactly the wrong conclusion. When in doubt, cross-check the insider's filings against the company's broader ownership on its stock holder page and the insider's full transaction history before drawing any conclusion.

FAQ

What is a GRAT on a Form 4 filing?

A GRAT, or grantor retained annuity trust, is an estate-planning trust. On a Form 4, a GRAT transfer appears as shares moving into the trust — an ownership-form change, not an open-market sale. It is used to pass stock appreciation to heirs in a tax-efficient way.

Does a GRAT transfer mean an insider is selling stock?

No. A GRAT transfer relocates shares within the insider's family planning structure rather than selling them on the market. It typically carries a "J" or transfer code with no sale price, distinguishing it from a genuine "S" open-market sale.

How can I tell a GRAT transfer from a real insider sale?

Check the transaction code (S means sale; J or a transfer code with a GRAT footnote means estate planning), look for whether a price per share is listed, and read the footnotes, which describe the nature of the transfer explicitly.

Why do corporate insiders use GRATs?

Insiders whose wealth is concentrated in company stock use GRATs to pass future appreciation to heirs while minimizing gift and estate taxes. The grantor receives fixed annuity payments back, and appreciation above a baseline rate passes to beneficiaries outside the taxable estate.

Is a GRAT transfer a bullish or bearish signal?

If anything, it leans bullish. GRATs work best when the contributed assets appreciate, so funding one signals an insider expects the stock to keep rising. It is the opposite of an unplanned discretionary sale, which can be a bearish data point.

Where can I see GRAT transfers in a company's filings?

GRAT transfers appear on an insider's Form 4 filings, viewable on the insider's profile page and cross-referenced against the company's stock holder page on 13F Insight. Look for the transaction footnotes that describe annuity-trust contributions.
