Griffith William J.G. has filed 108 Form 4 transactions across three companies, with a net buying bias. His open-market purchases total $48.98 million against $34.00 million in open-market sales, a spread of roughly $15 million. The buying has been concentrated and recent. On July 8, 2026, he bought $7.22 million of NTSK stock, followed by a $2.96 million purchase on July 10 and an $804,546 purchase on July 13. Those three buys, all in NTSK, account for $10.98 million of the total. The selling side is tied to TTAN. On June 22 and June 23, 2026, Griffith filed six open-market sales in TTAN totaling $5.99 million. The largest single sale was $3.38 million on June 23, with another at $2.52 million the same day. The remaining four sales were small, ranging from $5,355 to $50,766. He also received a TTAN grant on June 17, valued at zero, which is compensation rather than a purchase. The rest of the recent activity is mechanical. On August 3, 2026, Griffith filed three zero-value transactions in PCOR under code J, which is a conversion of a derivative security. He had a PCOR grant on June 4. On July 13, he filed six zero-value J transactions in TTAN. Four NTSK conversions on March 13, also zero value, round out the recent filings. The pattern is straightforward: he is putting cash into NTSK, trimming TTAN, and holding positions in PCOR without new money.
