Impact and Significance

The proposed sale represents a negligible fraction (<0.001%) of Natera's 144,144,170 outstanding shares. Given that the shares were acquired via routine RSU vesting on October 27, 2026, this transaction likely reflects routine personal financial planning or tax-withholding management, carrying low market significance.
