Was the MTRN CEO’s 14-share disposition an open-market sale?

No. The 14 MTRN shares were disposed of as a tax-withholding transaction, not an open-market sale. The shares were delivered to satisfy tax liabilities related to equity compensation, a routine administrative step that does not represent discretionary selling activity.
