A row is a disclosure, not an execution record: the filing reports a date, a bracket, and the reported owner, but not the price, share count, or reason. Compare the trade date with the filing date to see how long the transaction stayed private.
How long disclosure took
Days from trade date to filing date for 3 rows. The STOCK Act allows 30 days from notification and no more than 45 days from the trade. A late row is a timing fact, not evidence of wrongdoing.

What Gilbert Cisneros's TNDM filings don’t tell you
A disclosure row records a trade date, an amount bracket, and who owned the asset. It does not say why the trade was made, whether the position is still held, or anything about the business behind the ticker: revenue trends, margins, balance-sheet risk, or valuation. Those answers are in company filings, not congressional ones.
