Billingsley Chester, CEO of MNTR, has filed 128 Form 4 transactions, and every single one involving cash was a purchase. His total buy value stands at $94,765.41, with zero sales, zero acquisitions, and zero shares sold back to the issuer. The pattern is one-directional: Chester has not recorded an open-market sale in any filing.
The recent activity is dense and consistent. Between February 26 and April 14, 2026, Chester executed 23 open-market purchases of MNTR stock, all coded as "P" on his Form 4s. The individual amounts are small, ranging from $0.20 on April 1 to $210 on March 25. The largest recent buy was $204.58 on March 11, followed by $132.32 on March 2 and $124 on April 8. The smallest, a $0.20 purchase on April 1, is negligible in dollar terms but still counts as a buy. Two transactions on April 3 were coded "C" for conversion of a derivative security, with values of $0.65 and $0, meaning no cash changed hands.
The buying has been steady rather than clustered. Chester made purchases on March 2, 4, 5, 6, 9, 11, 12, 13, 16, 18, 19, 20, 25, and 26, then resumed on April 1 and bought again on April 7, 8, 9, 10, 13, and 14. The dollar values fluctuate but never approach a large block. The total across all 128 filings is under $100,000, which suggests incremental accumulation rather than a single decisive position. With no sales on record, Chester's disclosed behavior is a consistent buyer of MNTR shares.
