Trading Arrangements

During the quarter ended September 28, 2025, our directors and officers (as defined in Rule 16a-1(f) under the Exchange Act)adopted orterminated the contracts, instructions or written plans for the purchase or sale of Arlo’s securities set forth in the table below:

(1)Contract, instruction or written plan intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) under the Exchange Act.

(2)“Non-Rule 10b5-1 trading arrangement” as defined in Item 408(c) of Regulation S-K under the Exchange Act.

(3)Adopted for personal tax planning purposes.

(4)This plan covers shares underlying certain of Mr. Binder’s equity awards, and with respect to one such equity award, the actual number of shares to be sold will depend on (i) the shares granted to Mr. Binder in the first quarter of 2026 in settlement of his annual bonus (which is assumed to be achieved at 100% of target and settled using a price per share based on a 30-day average as of August 21, 2025, which was the adoption date of this plan), and (ii) state and federal tax rates applicable on the relevant vesting date. With respect to certain of the equity awards in this plan, Mr. Binder has designated certain target prices for the sale of shares, and if our stock is not trading at or above such target prices, the shares cannot be sold.

(5)The actual number of shares that may be sold under this plan is equal to the number of shares that remain unsold under Mr. Faison’s plan that was previously adopted on August 26, 2024 and disclosed in the Quarterly Report on Form 10-Q for the quarter ended September 29, 2024.

In addition, our officers (as defined in Rule 16a-1(f) under the Exchange Act) have entered into sell-to-cover arrangements adopted pursuant to Rule 10b5-1 authorizing the pre-arranged sale of shares to satisfy our tax withholding obligations arising exclusively from the vesting of RSUs and PSUs and the related issuance of shares. The amount of shares to be sold to satisfy our tax withholding obligations under these arrangements is dependent on future events which cannot be known at this time, including the future trading price of our shares. The expiration date relating to these arrangements is dependent on future events which cannot be known at this time, including the final vest date of the applicable RSUs and PSUs and the officer’s termination of service.
