Mauch Robert P.

Mauch Robert P., President & CEO of CoreSite Realty Corporation (COR), has demonstrated a consistent pattern of selling activity in recent months, with no recent purchases recorded in SEC filings. Since September 2025, Mauch has executed multiple sales of COR stock totaling approximately $21.4 million, offset by $2.5 million in buy transactions over his full trading history. The most recent transactions include a sale of $1.35 million worth of shares on February 20, 2026, following a $479,160 sale two days prior. Earlier disposals were similarly substantial, including a $1.81 million sale on January 20, 2026, and a $1.75 million transaction on December 18, 2025. The filings show Mauch’s sales are often paired with smaller market purchases (coded "M"), likely related to option exercises or tax obligations, such as the $323,871 acquisition on February 20, 2026, coinciding with his larger sale that day. Notably, his dispositions have been frequent, with seven sales in the most recent reporting period, all concentrated in COR. The absence of any recent buys and the recurring pattern of high-value sales suggest a directional reduction in his holdings, though the filings do not indicate whether these transactions are part of a prearranged trading plan. The activity remains confined to a single company, with no diversification across other securities in the reported period.
