Management Comments

• The reporting person confirmed that the sales were mandatory 'sell-to-cover' arrangements and not discretionary trades.

Industry Context

StockSavvy.ai notes that routine 'sell-to-cover' transactions by C-suite executives are standard practice in the technology sector to manage tax liabilities arising from equity compensation programs and generally do not signal a change in management sentiment regarding company prospects.

Comparison to Industry Standards

• The use of Rule 10b5-1 plans is a standard governance practice for executives at major tech firms like Meta, Alphabet, and Microsoft to avoid potential insider trading concerns.
• The 'sell-to-cover' mechanism is a common administrative procedure for equity-based compensation in publicly traded companies.

Corporate Governance

Related Party Transactions

• The reporting person serves as trustee for several family trusts (Susan P. Reinstra 2022/2023 Annuity Trusts, San Domenico Trust, Mark L. Reinstra 2022/2023 Annuity Trusts) which hold shares of the issuer.

Stakeholder Impact

• Minimal impact on shareholders as the sales were non-discretionary and tax-related.

Next Steps

• Continued monitoring of future Form 4 filings for any discretionary trading activity.
