OptiBiotix Health PLC: what insiders have been doing
OptiBiotix Health PLC is a listed company. Its insiders report their share dealings to RNS (LSE). Over the twelve months to 8 November 2026, 2 filings were filed, from 1 insider.
The flow runs one way only: 1 insider bought (2 purchases totalling €11k) and nobody sold on the market. The totals exclude 1 filing filed without an amount. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Those buying include 1 senior executive. At €11k, the purchase published on 29 May 2026 by David Blain is the largest of the period.
The most recent open-market purchase was published on 1 June 2026, 160 days ago.
With 2 filings in twelve months, the company is quieter than the median of 6 filings across the 833 companies we follow on the same exchange. Our records for OptiBiotix Health PLC go back to 2025, with 5 purchases and no sales on the open market in total.
