Brophy Michael Burkes, Chief Financial Officer of Natera Inc. (NTRA), has demonstrated a consistent pattern of selling company shares, with no recorded purchases across 49 reported transactions. SEC filings reveal Burkes has disposed of over $21.8 million worth of NTRA stock, with all 21 recent transactions being sales. The largest dispositions occurred in January 2026, including a $8.87 million sale on January 21 and a $5.62 million transaction the previous day. Other notable sales include a $1.13 million transaction on February 3, 2026, and multiple six-figure sales throughout late January and July 2026, ranging from $188,576 to $464,594. The activity shows concentrated selling in early 2026, with bursts of transactions in late January and early February, followed by another cluster in late July. While two awards (coded "A") and one merger-related transaction (coded "M") appear in the record, these involved no monetary value. The complete absence of buy transactions and the sustained selling pattern across multiple years suggests a deliberate reduction in equity exposure to Natera. The transactions span various price points, with no single dominant method or price range, indicating potentially systematic diversification rather than reaction to specific price movements. All sales occurred under Rule 16b-3, which provides affirmative defenses for officer transactions.
