Stakes of 5% or more
No 13D or 13G filing on MXL in the last two years from the filings we read (13G only for companies we track; the sweep began Sep 2026).
A 13D means the holder crossed 5% with intent beyond passive ownership and had to state a purpose; a 13G is the passive version. Every new 13D on tracked companies.
