REGRegency Centers · Insider ownership research

Regency Centers insiders sold $40.9M in the past 12 months. How much of their stake is that?

"% of total stake" is the shares in this event against all the vested shares the person held that day, across every share class and holding entity, after that day's vesting. "n/a" means the person's holdings don't reconcile, or the row is a purchase. "Holdings record incomplete" means more shares were sold than the filings show the person held that day, so a percentage would be wrong.

Is this normal? More than usual: about 3x the 5-year average. 6 insiders sold; the average is 5 a year. Year by year

Left out: Martin Stein Jr. and Gary Anderson (holdings couldn't be fully reconciled); Lisa Palmer, Nicholas Wibbenmeyer and Alan Roth (most of their shares vested during the period, so a percentage would mislead); Mark Parrell (held no vested shares at the start).
Disclosed company stock is not an insider's whole wealth.

Who sold, and how much of their stake

Officers and directors, past 12 months. Each bar is 100% of that person's own stake; not comparable between people. The stake is the vested shares held at the start of the period (Oct 9, 2025); the gold part is what they sold.

Common questions

Is the Regency Centers CEO selling stock?

Yes. Lisa Palmer sold 26K shares ($2.0M) in the past 12 months, none of it under a trading plan disclosed in the filings.

Why are Regency Centers insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 0% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 100% had no disclosed plan. A trading plan schedules sales in advance.

Are any Regency Centers insiders buying?

No. Officers and directors reported no purchases in the past 12 months.

How much of their stake did Regency Centers insiders sell?

About 4.3% overall. As a group they ended with more shares than they started with. These figures leave out Martin Stein Jr., the largest holder (holdings couldn't be fully reconciled). That covers the 12 months to Oct 9, 2026 and counts vested shares reported on SEC Forms 3, 4 and 5, which is not an insider's whole wealth.

16 of 18 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (16 exactly, 0 with a minor or footnoted difference). For 2 we show sales but not holdings; the ! icon on their rows explains why. Percentages cover 12 of 18 officers and directors. Left out: Martin Stein Jr. and Gary Anderson (holdings couldn't be fully reconciled); Lisa Palmer, Nicholas Wibbenmeyer and Alan Roth (most of their shares vested during the period, so a percentage would mislead); Mark Parrell (held no vested shares at the start). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

What explains the selling$40.9M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $40.9M across 525,272 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

No plan disclosed · $40.9M

Sales with no 10b5-1 plan and no tax reference in the filing. $36.4M of it is Martin Stein Jr.. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Martin Stein Jr., May 4, 2026

Taxes

69,614 shares ($5.1M) were withheld by the company for taxes, which isn't a market sale.

Open-market sales (Form 4 code S) by people who were officers or directors, in split-adjusted shares. Earlier years include people who have since left. A sale that an outside holder also reports (a family trust, a fund) is counted with outside holders in every year. Shares, not dollars, are compared, so a change in the stock price doesn't look like a change in selling. Years the filings don't fully cover are shown but left out of the average.

Known gaps and uncertainty2 insiders whose holdings couldn't be fully reconciled

Martin Stein Jr.: holdings couldn't be fully reconciled (difference of 205,577 shares). Balance changed without a matching transaction, and the footnote does not state the amount: +167,490 shares on Nov 10, 2025 (General Partnership). Filing, Nov 10, 2025

Footnote: "By two general partnerships, which the Reporting Person is a general partner."

Gary Anderson: holdings couldn't be fully reconciled (difference of -1,421 shares). Filings report each grant's shares as the balance instead of a running total. Filing, May 11, 2026

Footnote: "Vesting of restricted stock grant pursuant to Regency's Omnibus Incentive Plan."

Inferred rename: "a limited partnership, the general partner of which is controlled by Mr. Stein's family" is treated as the same holder as "Note 1", because the old name was never reported again and the new one opened with the same balance (160,263 shares). Old name, new name

Inferred rename: "two general partnerships in which Mr. Stein is a general partner" is treated as the same holder as "Note 2", because the old name was never reported again and the new one opened with the same balance (415,382 shares). Old name, new name

Inferred rename: "a trust for Mr. Stein's benefit" is treated as the same holder as "Note 3", because the old name was never reported again and the new one opened with the same balance (4,000 shares). Old name, new name

Inferred rename: "Note 3" is treated as the same holder as "two additional grantor retained annuity trusts, repsectively", because the old name was never reported again and the new one opened with the same balance (251,892 shares). Old name, new name

Inferred rename: "two additional grantor retained annuity trusts, repsectively" is treated as the same holder as "See Note 2", because the old name was never reported again and the new one opened with the same balance (196,528 shares). Old name, new name

Inferred rename: "Note 5" is treated as the same holder as "See Note 3", because the old name was never reported again and the new one opened with the same balance (160,263 shares). Old name, new name

Inferred rename: "Note 6" is treated as the same holder as "See Note 4", because the old name was never reported again and the new one opened with the same balance (415,382 shares). Old name, new name

Inferred rename: "See Note 2" is treated as the same holder as "two additional grantor retained annuity trusts, respectively", because the old name was never reported again and the new one opened with the same balance (196,528 shares). Old name, new name

External context: we only cite outside events when a documented connection exists. None is shown for this period.

Sources and methodology1,598 filings from SEC EDGAR, and how we read them

All 1,598 Forms 3, 4 and 5 filed for Regency Centers (SEC CIK 910606) from Jun 21, 1996 to Aug 7, 2026, retrieved from SEC EDGAR on Oct 9, 2026. Prices are the ones reported in each filing, often weighted averages. 72 older filings exist only on paper and could not be read.

Holdings. Each holding line (a share class plus an owner, such as a trust or LLC) carries its last reported balance forward. Entities first reported during the period start at zero, so transfers between an insider's own trusts don't count as selling. Lines not reported for three years or more are listed separately and left out of totals.

Sales. A sale counts as under a 10b5-1 plan if its footnote cites one or the filing's Rule 10b5-1 box is checked, and as tax-related if its footnote cites tax obligations or sell-to-cover. Shares withheld by the company for taxes are listed separately. Sales with neither attribute are labeled "no plan disclosed".
