Vinczeller Shiela, Chief Human Resources Officer, has demonstrated a consistent pattern of insider transactions focused solely on shares of ATR, as disclosed in SEC Form 4 filings. Over the course of 25 transactions, Shiela has exclusively engaged in selling and exercising options, with no recorded purchases. The total value of these transactions amounts to $783,711.12, reflecting a clear selling bias. Notably, Shiela’s most significant sale occurred on September 5, 2025, when shares worth $161,006.44 were disposed of. This transaction stands out as the largest single sale in the dataset. Recent activity continues to align with this trend. Between February 24, 2026, and March 19, 2026, Shiela executed multiple transactions, including sales and exercises of options, totaling $180,585.85 in value. These included a $18,000.50 sale on March 17, 2026, and a $42,840.45 transaction on March 15, 2026. Earlier in 2026, Shiela also exercised options and sold shares on February 23, 24, and 25, with values ranging from $13,697.28 to $31,566.66. This consistent pattern of exercising options and selling shares suggests a strategic approach to managing equity holdings in ATR. Shiela’s transactions are concentrated entirely within ATR, indicating a focus on this single company. The absence of buying activity and the recurring nature of sales and option exercises highlight a clear disposition toward reducing equity exposure in ATR over time. This activity provides a transparent view of Shiela’s insider trading behavior, reflecting a sustained and deliberate approach to managing personal holdings in the company.
