High conviction

This is a high-conviction signal — the insider is a first-time or occasional buyer, historically the strongest subset. Such buys have outperformed the S&P 500 by a median ~3% over the 30 days after the trade (n ≈ 3,001, 2024-2026). Past results don't predict the future. How we measure this ↗

AECOM president Lara Poloni bought 4,224 shares ($298.3K) at $70.63 as stock down 47.9% from 52-week high

Lara Poloni, AECOM's president, purchased 4,224 shares for $298,341.12 on 2026-06-16 at $70.63 per share, raising her holdings from 149,222 to 153,446 shares. The transaction occurs with ACM trading at a significant discount—47.9% below its 52-week high of $135.52 and down 21.6% over the past 90 days. Her prior trading activity at ACM shows a strong pattern: all 3 previous transactions were sells, and all 3 were well-timed at the 90-day mark, with cumulative 90-day returns of -7.4%, -8.6%, and -1.2%. This buy represents a shift in her recent trading direction at this ticker, following a history of timely exits before declines. The timing coincides with depressed valuation relative to recent trading ranges, though the company maintains solid fundamentals with $3.8B in quarterly revenue and a P/E of 17.97.

Significance 6

CFO Kapoor Gaurav buys 1,420 shares of AECOM (ACM) at $71.12; stock down 47.6% from 52-week high of $135.52.

CFO Kapoor Gaurav purchased 1,420 shares at $71.12 on 2026-05-14, raising his holdings to 88,053 shares. The buy occurs after significant stock deterioration: the current price of $71.00 is 47.6% below the 52-week high of $135.52, and the stock has declined 16.6% over 30 days and 19.6% over 90 days. While insider buying during weakness can signal conviction in valuation, the magnitude of the decline and the executive's modest purchase size relative to his large existing position warrant scrutiny regarding whether this reflects opportunistic averaging or other factors. The company maintains solid fundamentals with $3.8B in quarterly revenue and a P/E of 18.07, though annual revenue growth is minimal at 0.2%.

Significance 6

CEO Rudd Troy buys 4,225 shares of AECOM at $71.02; stock down 47.6% from 52-week high

CEO Rudd Troy purchased 4,225 shares for $300,059.50, bringing his holdings to 142,207 shares, at a time when ACM is trading at $71.00—47.6% below its 52-week high of $135.52 and down 16.6% over the past 30 days. His historical sell activity shows a poor timing pattern (0.00% well-timed rate on 15 prior sales with avg 90d return +8.1%), suggesting limited predictive value from his past transactions. The current buy occurs amid significant recent weakness and declining momentum, though the company maintains a P/E of 18.07 and generated $179.9M in net income on $3.8B in revenue last quarter. This open-market purchase by the CEO at depressed valuations warrants attention as a potential conviction signal about near-term support, though his track record of poorly-timed exits raises questions about execution judgment.

Significance 5

AECOM President Poloni Lara sold 17,533 shares for $1.7M at blended avg $97.02; stock now $96.69, down 28.0% from 52-week high

Polani Lara, PRESIDENT of AECOM, executed 2 separate sales totaling 17,533 shares (a 10.5% reduction from 166,755 pre-transaction holdings) for $1,701,134.95 at an average price of $97.02 per share on 2025-12-17. The company trades at $96.69 today, near the bottom of its 52-week range and down 26.7% over the trailing 30 days and 27.3% over 90 days. His prior sale at ACM in December 2023 showed neutral timing (90d return -1.2%), and his cross-ticker track record of 1 prior sell yielded a 100.0% well-timed rate at the 90d mark. The current transaction occurs as AECOM's stock has experienced sharp recent weakness from its $134.35 52-week high, though fundamentals remain modest (P/E 16.47, $131.0M net income on $4.2B revenue with +0.2% annual growth). The sale's significance is elevated by the material dollar value and substantial share count reduction, though motivation remains unclear absent explicit plan disclosure.

AECOM CLO Gan David Y. sold 15,502 shares for $1,514,889.02 under pre-arranged 10b5-1 plan

Gan David Y., Chief Legal Officer of AECOM, executed 2 separate sales totaling 15,502 shares for $1,514,889.02 on 2025-12-15 and 2025-12-17 at an average price of $97.72. The transaction is part of a pre-arranged 10b5-1 trading plan adopted on 2025-08-15, meaning it is scheduled and non-discretionary rather than a response to current market conditions. Following the sales, his post-transaction holdings stand at 41,549 shares, representing a -27.2% reduction from pre-transaction holdings of 57,051 shares. As a scheduled transaction under a 10b5-1 plan, this sale reflects a predetermined execution plan established several months prior and does not signal discretionary timing or conviction decisions by the insider.

CEO Troy Rudd sells entire 53,097-share stake in ACM for $6,348,193.77 via 10b5-1 plan

Troy Rudd, CEO of AECOM, executed 2 separate sales on 2025-08-15 totaling 53,097 shares for $6,348,193.77, liquidating his entire shareholding (100.0% reduction). The sales occurred at $119.41 and $120.12, yielding a blended average price of $119.56. This transaction is part of a pre-arranged 10b5-1 trading plan adopted on 2024-02-11, meaning the timing and structure were set in advance and do not reflect discretionary decision-making around current market conditions. Complete divestiture of a CEO's holding warrants documentation of the stated rationale in the filing, as markets typically scrutinize full insider exits regardless of their scheduled nature.

Significance 5

CLO Gan David Y. sold 20,898 shares of ACM for $2.3M across 4 transactions (Dec 16-18), reducing stake by 33.8% to 41,015 shares

Gan David Y., Chief Legal Officer of AECOM, executed 4 separate sales totaling 20,898 shares for $2,319,780.16 at a blended average price of $111.00 per share between December 16–18, 2024. This represents a substantial reduction in his holdings from 61,913 shares to 41,015 shares (a 33.8% reduction of pre-transaction holdings). The transaction occurred near the upper end of the company's 52-week range ($82.37–$116.97), with transaction prices ($110.19–$111.67) tracking 3–6% below the 52-week high of $116.97. The timing of these sales, concentrated in a narrow 3-day window, and the magnitude of the reduction warrant assessment against any scheduled trading plan disclosure. The current stock price of $106.93 is 8.6% below the 52-week high but remains above recent 30-day depreciation of 2.0%, suggesting the insider sold into relative strength.

CFO Gaurav Kapoor sold 42,400 ACM shares at $115.34 (Nov 6, 2024) via pre-arranged 10b5-1 plan; retains 31,228 shares post-sale.

As a scheduled transaction under Rule 10b5-1, this sale does not reflect discretionary decision-making at the current moment but rather a pre-arranged execution consistent with a plan established approximately 20 months prior. The CFO retains a material position of 31,228 shares post-transaction, indicating continued ownership stake in the company.

Significance 4

ACM CEO Rudd Troy sold 100,000 shares for $10.2M across 7 transactions via pre-arranged 10b5-1 plan.

Rudd Troy, Chief Executive Officer of AECOM, executed 7 separate sales totaling 100,000 shares (100.0K shares) for $10,245,210.65 ($10.2M) between October 1–3, 2024, at a blended average price of $102.45 per share. This disposition reduced his holdings from 277,555 shares to 177,555 shares, representing a 36.0% reduction in his pre-transaction position. The FLAG indicates this transaction is part of a pre-arranged 10b5-1 trading plan adopted on 2024-05-09 and is therefore scheduled and non-discretionary. Scheduled trades under Rule 10b5-1 are established in advance and execute mechanically, removing timing discretion from the executive and limiting their evidentiary value as signals of confidence or concern about the company's prospects.

CEO Rudd Troy sold 34,710 shares (34.7K) for $3.3M under pre-arranged 10b5-1 plan on 2024-08-15

Rudd Troy, CEO of AECOM, executed 2 separate sales totaling 34,710 shares for $3,344,485.94 at an average price of $96.36 on 2024-08-15. These sales were conducted pursuant to a pre-arranged 10b5-1 trading plan adopted on 2024-05-09, meaning the transactions were scheduled rather than discretionary. Following the sales, Troy maintained 277,555 shares (277.6K shares) in post-transaction holdings, representing an 11.1% reduction from his prior position of 312,265 shares. The scheduled nature of the plan means this transaction reflects an established trading schedule rather than a contemporaneous market decision.
