The period balance: money in, money out
In the Form 4 filings submitted between Sep 2, 2025 and Aug 18, 2026 there is not one open-market purchase of NiSource Inc.: 9 sales worth $5.3M and zero dollars bought.
Only codes P and S count, where an insider puts in or takes out their own money. A selling balance like NiSource Inc.'s is the norm in the S&P 500, where much of the pay comes as stock. It is not a recommendation to buy or sell: it is what was filed.
Every transaction, code by code
| Code | What it means | Trades | Reported amount |
|---|---|---|---|
| A | Grant or award | 27 | $33.9M |
| F | Tax withholding (shares surrendered for taxes) | 10 | $14.2M |
| S | Open-market sale | 9 | $5.3M |
| J | Other transaction (explained in the filing) | 1 | $0 |
| Total | Everything filed in the period | 47 | $53.4M |

Who has traded
Over the 15 months of history, 19 distinct people or entities have filed NiSource Inc. transactions: none bought on the open market and 6 sold. Counted by CIK, the fixed number the SEC gives each filer, and not by name, which each filer types their own way.
Of the 6 who sold on the open market (9 sales in all), the three biggest sellers account for $4.2M of the $5.3M: 78% of the money in three people.

How to read this data
2 of the 9 sales in the table are flagged as scheduled (10b5-1 plan): signed months ahead and executed automatically, so they say nothing about what the insider thinks today. NiSource has no open-market purchase (code P) in the history, the most common case in the S&P 500: insiders are already paid in stock. The latest filing is from Aug 18, 2026, and a Form 4 arrives up to two business days after the trade.
18 of the 20 rows in the table carry footnotes from the Form 4 itself, folded into the code column and copied verbatim; a row with no footnote means the filing has none.
