Zentek Ltd.: what insiders have been doing
Zentek Ltd. is a Chemicals company. Its directors and officers file their transactions with SEDI. From 5 November 2025 to 5 November 2026, the disclosure feed for Zentek Ltd. logged 38 filings by 7 insiders.
Not one open-market sale was filed. On the buying side, 2 insiders reported 8 purchases totalling €34k. Unlike grants, an open-market purchase is paid for by the insider, at the market price. On the buying side, the filings list 2 senior executives among the declarants. At €13k, the purchase published on 1 September 2026 by Wallman, Eric is the largest of the period (0.030% of market cap).
The most recent open-market purchase was published on 4 November 2026, 6 days ago. Between a trade and the moment it shows up on SEDI, the median delay is 3 days. This delay matters because a trade only becomes useful information once it is public.
Compared with its exchange (2,732 companies, median 15 filings), a count of 38 filings is above the norm. The full history, which starts in 2026, counts 8 purchases against no sales.
Elsewhere in the same sector, our signals recently picked up insider purchases at Symrise AG. This summary is built from SEDI disclosures alone and does not predict where the share price will go.
