ZILLMER JOHN J has been actively involved in insider trading across three companies—ARMK, CSX, and ECL—as evidenced by 29 transactions reported in SEC Form 4 filings. The data reveals a clear bias toward buying, with total buy values significantly outweighing sell values. Specifically, ZILLMER’s total buy value amounts to $2,913,937.25, compared to $1,410,815.11 in total sell value. Notably, the majority of these transactions involve ARMK, with substantial purchases such as a $1,900,016.28 acquisition on December 1, 2025, and multiple smaller buys throughout late 2025. ECL also features prominently, with purchases totaling $264,672.50 on February 13, 2026, and $248,039 on February 19, 2025. CSX, while part of the activity, shows no reported monetary value in recent transactions, suggesting they may involve non-monetary adjustments or grants.
Recent activity indicates a continuation of this buying trend, with ZILLMER’s latest transaction on February 13, 2026, involving ECL shares valued at $264,596.58. Notably, there have been no recent sell transactions, reinforcing the pattern of accumulation. The data underscores ZILLMER’s consistent investment in ARMK and ECL, with CSX playing a smaller, less financially significant role in the overall portfolio. This transactional behavior highlights a strategic focus on acquiring shares in these companies, particularly ARMK, which dominates the activity both in frequency and monetary value.
