Additional SEC filing notes

Filing notes and footnotes

Rule 10b5-1 trading plan

These transactions were reported as open-market trades under a Rule 10b5-1 plan. The plan lets an insider set trading instructions in advance, which can reduce the risk of trading while in possession of material nonpublic information.

Original filing language: transaction made pursuant to a contract, instruction, or written plan intended to satisfy Rule 10b5-1(c).

Explanation of responses 3 footnotes

Footnote F1

The sale was effected pursuant to a Rule 10b5-1 trading plan adopted by the reporting person on February 26, 2026.

Footnote F2

Amounts reflect the shift from indirect to direct ownership of 1,000 shares to correct an administrative error in the reporting person's Form 4 filed on June 2, 2026, which was carried over on the reporting person's Form 4 filed on June 5, 2026. The June 2, 2026 filing inadvertently reported that the sale of 1,000 shares was deducted from the reporting person directly, rather than the Christopher Paisley TTEE Paisley Living Trust DTD 12/28/94. Total beneficial ownership was correctly reported on both prior filings.

Footnote F3

The shares are held by the Christopher Paisley TTEE Paisley Living Trust DTD 12/28/94.
