Tamboran Resources Corporation
An energy company drilling for unconventional natural gas in Australia's remote Northern Territory, Tamboran Resources explores and develops the vast Beetaloo Basin, one of the world's largest untapped shale-gas regions, to help feed Australia's domestic market. Founded in 2009 and based in Sydney, it holds the largest operated land position in the basin, using drilling techniques borrowed from North American shale plays to tap gas locked in ancient rock.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over all recorded history: +1.15M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
