Beta40% was sold under disclosed trading plans, 60% to cover taxes. The largest seller, Ronald Silver (Pfo & Pao), sold $831K.Share-of-stake figures for this company are being verified and will be added when that check is finished. Why
Routine activity: 40% of sales were under disclosed plans, and no insider sold more than 1% of vested holdings.
A share of stake is shown for 0 of the 7 officers and directors who sold. 15 are left out Disclosed company stock is not an insider's whole wealth.i
Left out: Thomas MCCOURT, Mark Currie, Michael Shetzline, Minardo John, Ronald Silver, Alexander Denner, Tammi Gaskins, Andrew Dreyfus, Julie McHugh, Jon Duane, Gregory Martini, Jay Shepard, Marla Kessler, Catherine Moukheibir and Jeffrey Silber (share of stake is being verified).
Officers and directors, past 12 months. Their share of stake is being verified and is not shown yet; amounts and trading plans are below.
Officers and directors, Oct 2025 to Oct 2026. Each sale is counted once: under a disclosed plan, else to cover taxes, else no plan disclosed.
No officer or director trades were reported for the past 30 days. The most recent before that:
| Who | Shares | Price | % of total stake | Total stake after | Trade date | Filed |
|---|---|---|---|---|---|---|
| Ronald Silver Pfo & Pao | 127,890 | $4.52 | n/a | n/a | Jul 7, 2026 | Jul 9, 2026 |
Alexander Denner (for the outside shareholder represented on the board) sold $20.5M in the past 12 months. Large shareholders and the funds or companies that board members represent are not part of management, so they are left out of the figures above.
Yes. Thomas MCCOURT sold 198K shares ($740K) in the past 12 months, none of it under a trading plan disclosed in the filings.
Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 40% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 60% were to cover taxes. A trading plan schedules sales in advance.
No. Officers and directors reported no purchases in the past 12 months.

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.
Holdings and share of stake are being verified. Balances, unit counts and every share-of-stake figure for Ironwood Pharmaceuticals Inc are held back until that check is finished. Sales, proceeds, plan and tax status, titles and dates come straight from individual filings and are complete.
External context: we only cite outside events when a documented connection exists. None is shown for this period.
All 804 Forms 3, 4 and 5 on record for Ironwood Pharmaceuticals Inc (SEC CIK 1446847), filed from Feb 2, 2010 to Sep 17, 2026; 28 of them were filed in the 12 months this page covers, retrieved from SEC EDGAR on Oct 16, 2026. Prices are the ones reported in each filing, often weighted averages. 2 filings were left out because Ironwood Pharmaceuticals Inc filed them as an owner of another company's stock.
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".
