#### COMPANY PROPOSAL 5
<div align='center'>Approval of an Amendment to the Align Technology, Inc. 2005 Incentive Plan</div>

Our 2005 Incentive Plan, as amended and restated (the “Incentive Plan”), allows Align to grant stock options, restricted stock, restricted stock units, performance shares, performance units, stock appreciation rights and other stock-based and cash incentives to our employees and other eligible service providers. Our stockholders last approved, at our 2023 annual meeting of stockholders, the Incentive Plan as amended and restated and approved by our Board in March 2023. On March 19, 2025, our Board approved an amendment of the Incentive Plan (the “Incentive Plan Amendment”) solely to increase the number of shares authorized for issuance under the Incentive Plan by 2.5 million, from 32,168,895 to 34,668,895 shares.

The Incentive Plan has not been materially amended with respect to any other terms or provisions since stockholders last approved the Incentive Plan in 2023. To the extent stockholders do not approve this Proposal 5, the Incentive Plan will continue as if the Incentive Plan Amendment did not apply and was not adopted by the Board.
