Earlier Insider Trading filings

Filed: 2026-05-13

Kevin Carpenter, SVP-Chief Supply Chain Officer, acquired 28,509 restricted stock units (RSUs) at $0 price, representing compensation rather than open market purchase, indicating continued equity incentivization of senior management.
The RSUs vest in two tranches over approximately 12-15 months (beginning March 1, 2027 and May 18, 2027), suggesting the company is using time-based vesting to retain key supply chain leadership during what may be a critical operational period.
This is a non-discretionary equity grant as part of standard long-term incentive compensation programs, which is routine executive compensation activity with no insider selling pressure or trading signal implications.

Filed: 2026-05-13

Director Sharp acquired 2,619 restricted stock units (RSUs) valued at $0 acquisition price on May 12, 2026, as part of standard annual director compensation, indicating routine equity grants rather than discretionary insider buying.
The RSUs vest on May 12, 2027, or at the next Annual Meeting of Stockholders (whichever comes first), representing a standard one-year vesting schedule typical for director compensation packages.
Sharp's total beneficial ownership increased to 5,733 shares following this transaction, but the transaction reflects automatic compensation allocation rather than market confidence signals that would accompany voluntary insider purchases.
The filing was executed by an attorney-in-fact (Tiffany B. Williams) rather than the director personally, which is routine administrative practice for director compensation grants but suggests no special circumstances around this acquisition.

Director Stephen E. Macadam received 2,619 Restricted Share Units (RSUs) as part of annual director compensation on May 12, 2026, with full vesting occurring on May 12, 2027 or at the next Annual Meeting of Stockholders.
This is a routine equity compensation grant at $0 purchase price, indicating standard director compensation practices rather than discretionary insider buying or selling.
Macadam's beneficial ownership increased to 38,588 shares following this RSU grant, reflecting his ongoing role as a board director with vested interests in company performance.
The transaction involves no material trading activity or concerning insider selling patterns; this is a compensation-related event rather than a market signal about company outlook.

Filed: 2026-05-13

Director Jane Leipold acquired 2,619 restricted share units (RSUs) as part of 2026-2027 annual director compensation on May 12, 2026, with full vesting on May 12, 2027 or at the next Annual Meeting, whichever occurs first.
The grant of RSUs at $0 price represents standard director compensation equity awards rather than discretionary open-market purchases, indicating normal governance practices without any indication of insider confidence through personal capital deployment.
Following this transaction, Leipold directly owns 20,538 shares, representing a modest director-level position that does not suggest significant personal investment conviction in ATMU at current levels.

Filed: 2026-05-13

Director Stuart A. Taylor II acquired 2,619 restricted share units (RSUs) on May 12, 2026, as part of standard annual director compensation, with no purchase price paid, indicating this is a routine equity grant rather than open market buying activity.
The RSUs vest on May 12, 2027, or at the next Annual Meeting of Stockholders (whichever is earlier), representing a typical one-year vesting schedule for director compensation that aligns leadership incentives with shareholder interests.
Taylor's total beneficial ownership following this transaction is 11,697 shares held directly, suggesting a modest director-level stake in the company without evidence of significant insider confidence through discretionary purchases.

Filed: 2026-05-13

Director Diego Donoso received 2,619 restricted share units (RSUs) valued at $0 as part of standard 2026-2027 annual director compensation, with full vesting occurring on May 12, 2027 or at the next Annual Meeting of Stockholders.
The RSU grant at $0 price indicates this is a non-cash equity compensation award rather than a market purchase, representing routine director retention and incentive alignment practice.
Donoso's post-transaction beneficial ownership increased to 11,697 shares, suggesting meaningful existing stake in the company prior to this director compensation grant.
The filing was executed by attorney-in-fact Tiffany B. Williams on May 13, 2026, one day after the transaction date, indicating proper compliance with SEC reporting requirements.
