TDC TERADATA CORP /DE/ Insider Trading

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.

TDC CEO McMillan sells 50.0K shares at $30.26; stock now $31.49. 2 of 3 prior same-ticker sells were well-timed; 90d avg -6.8% on his cross-ticker record.

Stephen McMillan, President and CEO of Teradata, sold 50,000 shares on 2026-02-26 at $30.26, reducing his holdings from 713.2K to 663.2K shares (-7.0%). The current price of $31.49 is 16.9% below the 52-week high of $37.88, and the stock has posted +6.1% gains over 30 days and +10.0% over 90 days. McMillan's cross-ticker track record shows 3 prior sells with an average 90-day return of -6.8% and a 66.67% well-timed rate, while his same-ticker history at TDC shows 2 of 3 prior sales were well-timed at the 90-day mark. Against a backdrop of -5.0% annual revenue decline and a P/E of 21.72, the sale signals modest portfolio adjustment by the CEO at a price below recent highs, though the timing pattern does not definitively establish forward-looking conviction either way.

Lynrock Lake LP (10% owner) sold 61,990 shares across 3 transactions for $2,497,507.35 at blended average $40.29

Lynrock Lake LP, the 10% owner, executed 3 separate sales totaling 61,990 shares (62.0K shares) for $2,497,507.35 on 2026-02-11, reducing holdings from 9,416,666 shares to 9,354,676 shares (-0.7% of prior position). The sales occurred at a blended average price of $40.29, while the current price is $33.56, representing a 20% decline from the transaction prices. The insider's cross-ticker track record shows a negative average 90-day return after prior sales of -1.9% with a 26.32% win rate, suggesting a history of poorly-timed exits. With annual revenue growth at -4.5% and a P/E of 26.43, the fundamental backdrop appears challenged, yet the stock has risen 9.7% over 30 days and 23.2% over 90 days, indicating recent momentum recovery from the 52-week low of $19.20.

Teradata CFO (then) BRAMLEY CLAIRE sold 35,464 shares for $809,646.46 via scheduled 10b5-1 plan

BRAMLEY CLAIRE, who was CFO at the time, executed 4 separate sales totaling 35,464 shares for $809,646.46 on 2025-03-10 under a pre-arranged 10b5-1 trading plan adopted 2024-09-12. The blended average sale price was $22.83 across transactions ranging from $22.82 to $23.52 per share. Post-transaction holdings of 105,833 shares represent a 25.1% reduction in her position. Because this transaction is scheduled under a 10b5-1 plan rather than discretionary, it reflects a pre-determined trading schedule set months in advance and does not convey timing-based insight into near-term stock performance or management's contemporaneous confidence in valuation.

Ashton Hillary (CPO) sold 54.6K shares of TDC for $1.6M on Nov 7, reducing stake 45.0% to 66.8K shares.

Ashton Hillary, Chief Product Officer of Teradata, liquidated 54,610 shares at $29.10 on 2024-11-07 in a substantial single transaction reducing his holdings by 45.0%. At the same-ticker level, his prior two 2024 sales at TDC resulted in negative 90-day returns (-0.3% and -15.4%), while one 2023 sale posted +7.3%, giving a 2-of-3 well-timed rate at this ticker. His cross-ticker track record shows a 66.67% well-timed rate across 3 prior sells with an average 90-day return of -7.8%. The current price of $29.89 is -39.0% below the 52-week high of $48.99, and the stock has fallen 2.8% over the past 30 days despite a +15.2% 90-day rise, suggesting recent volatility. With a P/E of 34.76 and annual revenue growth of only 2.1%, the valuation context is notable for a mature data analytics vendor.

CEO McMillan sells 20,000 TDC shares at $30.00; stock now $29.89, down 39.0% from 52-week high of $48.99

McMillan, as President and CEO of Teradata, sold 20,000 shares (373.6K shares remain post-transaction) at $30.00 on 2024-11-08. The stock currently trades at $29.89, down 39.0% from its 52-week high of $48.99, suggesting a material pullback from recent peaks. His prior two sales at TDC were well-timed at the 90-day mark, with subsequent declines of -13.7% and -9.5%, respectively; this sell occurred at a price closer to current levels in a depressed market. The company carries a P/E of 34.76 with annual revenue growth of +2.1%, modest fundamentals that may reflect ongoing headwinds. The timing of this sale relative to the stock's steep decline from its 52-week high merits monitoring, though the sale was executed at a price not substantially above current market levels.
