CRO Richard J Petley sells 17,227 shares at $35.00–$35.01 on TDC; scheduled 10b5-1 plan

Richard J Petley, Chief Revenue Officer, executed 2 separate sales totaling 17,227 shares for $602,952.03 under a pre-arranged 10b5-1 trading plan adopted on 2025-12-05. His post-transaction holdings of 188,571 shares represent an 8.4% reduction from pre-transaction holdings of 205,798 shares. The stock currently trades at $36.51, above the blended average price of $35.00 at which the sales occurred. Teradata's fundamentals show quarterly revenue of $444,000,000.00 and net income of $335,000,000.00, with annual revenue declining 5.0% year-over-year and a P/E of 8.17. Because this transaction is scheduled under a 10b5-1 plan rather than discretionary, the filing reflects predetermined execution rather than a timing-driven decision.

TDC CEO Stephen McMillan sells 20,000 shares worth $634K; fifth open-market sale at the company in 36 months.

Stephen McMillan, Teradata's President and CEO, sold 20,000 shares on May 12, 2026, representing a modest reduction from his direct holdings. This is the fifth open-market sale McMillan has executed at Teradata within the past three years, continuing an established pattern of selling rather than buying. The stock was trading below its 52-week high at the time of the sale. Looking at prior outcomes, McMillan's previous sales at Teradata show mixed timing: at the 90-day horizon, two of his three evaluated prior sales preceded stock gains (poorly-timed exits), while one preceded a decline (well-timed). His most recent prior sale in February 2026 saw conflicting results—the stock fell sharply in the following month but recovered over a longer timeframe. Teradata remains a profitable company, though recent fundamentals show declining revenue growth and modest near-term earnings momentum, which provides limited context for interpreting this disposition as either a structural concern or routine portfolio management.

Chief Revenue Officer Petley sells 34,317 shares for $1.06M as stock pulls back from recent highs.

Chief Revenue Officer Richard J. Petley liquidated a meaningful portion of his holdings in a single transaction, disposing of roughly fourteen percent of his stake. The sale comes as the stock has retreated notably from its recent peak, though it remains modestly higher than it was earlier in the year. Teradata itself is a profitable company with significant revenue scale, supporting a valuation at a reasonable multiple to earnings. Petley's filing history shows he has not previously bought or sold shares on the open market during the prior three-year period—his past Form 4 filings involved only stock-based compensation transactions. This marks his first open-market sale, making the timing and scale noteworthy: a substantial liquidation of his position during a pullback, without a pattern of prior trading to contextualize whether this represents a shift in his relationship with the company.
