EVP Kathryn M Horgan sold 5,500 STT shares at $162.78 on 2026-06-11 via scheduled 10b5-1 plan; retains 108,694 shares.

Kathryn M Horgan, Executive Vice President, sold 5,500 shares of STATE STREET CORP at $162.78 for $895,290.00, reducing her holdings from 114,194 to 108,694 shares. This transaction was executed under a pre-arranged 10b5-1 trading plan adopted on 2026-03-12, meaning it was scheduled and not discretionary. Her prior trades at STT show mixed outcomes: a 2026-02-23 sale resulted in -0.1% after 30 days, while other recent STT sales (2025-11-28, 2025-05-30, and 2024-08-15) saw 30-day returns ranging from +1.3% to +11.6%. The current stock price of $167.37 is -1.9% from the 52-week high of $170.54, and the stock has gained +9.5% over 30 days and +37.7% over 90 days since this sale date.

W. Bradford Hu, EVP and Chief Risk Officer, sold 9,212 shares of STATE STREET CORP on 2026-05-26 at $155.35, reducing his holdings from 68,764 to 59,552 shares—a 13.4% reduction. This sale was executed under a pre-arranged 10b5-1 trading plan adopted on 2026-02-24, making it a scheduled transaction rather than a discretionary decision. STATE STREET is trading at $157.61 against a 52-week high of $159.31, with the stock up 22.5% over 90 days and 3.4% over 30 days. The company's fundamentals show quarterly revenue of $3,796,000,000.00 with net income of $764,000,000.00, and annual revenue growth of 7.3%, with a P/E of 14.24 and market cap of $43,621,252,071.13. As a pre-arranged plan, this transaction carries no signal regarding Hu's current assessment of company conditions.

State Street CEO Hanley sold 14,553 shares at $155.35 via pre-arranged 10b5-1 plan on 2026-05-26

Hanley Ronald P O, who was Chairman, CEO and President at the time, sold 14,553 shares (14.6K shares) of State Street on 2026-05-26 at $155.35, reducing his holdings by 5.4% to 255,512 shares. This transaction was executed under a pre-arranged 10b5-1 trading plan adopted on 2025-11-26, meaning it was scheduled rather than discretionary. His prior trades at State Street show mixed 30-day returns (+2.0%, +1.0%, +1.5%, +1.3%, +10.2%) but consistently positive 90-day returns ranging from +1.4% to +25.6%, though this historical pattern does not determine the significance of this particular scheduled sale. The stock currently trades at $157.61, near the 52-week high of $159.31, with State Street showing solid fundamentals including $3.8B in latest quarterly revenue, $764.0M net income, and a P/E of 14.24.

State Street COO Tahiri Mostapha sold 9,611 shares at $152.93 for $1.5M, reducing holdings by 12.9%

Tahiri Mostapha, EVP and COO of State Street Corp, executed a sale of 9,611 shares at $152.93 on 2026-04-22, reducing his holdings from 74,253 shares to 64,642 shares. The sale occurred near the stock's 52-week high of $153.57, with the company recently posting strong operational momentum: revenue of $3.5B, net income of $861.0M in the latest quarter, and annual revenue growth of 7.3%. The 30-day price change of +18.8% and 90-day change of +19.6% indicate significant recent appreciation prior to this sale. As a senior executive with material holdings, this activity warrants observation in the context of recent stock performance and the company's operational trajectory.

EVP John Plansky sells 16.1K STT shares at $124.32, reducing stake 22.3%; stock now -9.6% from high

John Plansky, Executive Vice President, sold 16,100 shares of State Street on 2026-03-11 at $124.32, reducing his holdings from 72,262 to 56,162 shares (a -22.3% reduction). The transaction occurred when STT was trading -9.6% from its 52-week high of $136.29, and the stock has declined -6.8% over the past 30 days and -3.5% over 90 days. His prior three sales at State Street produced positive 90-day returns of 27.3%, 10.0%, and 16.2% respectively (collectively not well-timed for detecting downturns), suggesting his historical sales at this ticker have preceded rallies rather than declines. The company remains fundamentally solid with $3.5B in quarterly revenue, $861.0M in net income, and a 10.60 P/E ratio, but the recent price weakness and Plansky's continued reduction of his concentrated position warrant monitoring to determine whether this reflects confidence-neutral rebalancing or emerging headwinds.

STATE STREET CORP Director Porter purchases 2,500 shares at $124.99; holdings rise 39.1% to 8,898 shares.

Director Brian J. Porter purchased 2,500 shares of STATE STREET CORP at $124.99 on 2026-03-05, increasing his holdings from 6,398 to 8,898 shares—a 39.1% increase in his position. The purchase occurred when the stock was trading near its 52-week high of $136.29 (currently $121.93, down 10.5% from that peak and down 7.9% over the past 30 days). STATE STREET trades at a P/E of 10.49 with a $34.0B market cap and posted $3.5B in latest quarterly revenue with net income of $861.0M and annual revenue growth of 7.3%. The director's open-market acquisition is a factual signal of insider investment; however, given the stock's proximity to its 52-week high at time of purchase and recent price weakness, the transaction merits examination of broader market context to understand the underlying motivation.

Significance 4

CEO Ronald O'Hanley sold 29.1K STT shares at $125.70 on 2026-03-02 for $3.7M; retains 270.1K shares.

O'Hanley sold 29,107 shares (9.7% reduction) at $125.70, bringing holdings to 270,065 shares. His same-ticker history shows 5 prior STT sells, none of which were well-timed at the 90-day mark—all five posted positive 90-day returns ranging from +1.4% to +19.8%, indicating the stock rose after each prior sale. State Street's current valuation shows a P/E of 10.89, annual revenue growth of +7.3%, and quarterly revenue of $3,545,000,000.00; the stock is currently -7.2% from its 52-week high of $136.29. The recurring pattern of prior sales followed by stock appreciation, combined with the CEO's retention of substantial holdings (270.1K shares remain), provides limited clear directional signal about near-term prospects.

Significance 5

STT EVP Joerg sold 8,765 shares at $128.00 on 2026-02-23 for $1.1M; holds 53,925 shares post-transaction.

AMBROSIUS JOERG, Executive Vice President of State Street Corp, sold 8,765 shares at $128.00, reducing his holdings by 14.0% to 53,925 shares. The sale occurred at a price $3.62 below the current price of $131.62 and near the middle of the 52-week range of $75.33–$136.29. This represents a discretionary reduction in a substantial executive position, though without scheduled trading plan disclosure, the timing context and motivation cannot be determined from the filing alone. Investors should monitor whether this reflects normal portfolio management by a mid-level executive or signals broader sentiment among State Street's leadership.

STT EVP Kathryn M Horgan sold 5,676 shares at $127.10 on 2026-02-23; holds 104,687 shares post-transaction.

Kathryn M Horgan, Executive Vice President at State Street Corp, sold 5,676 shares (104.7K held post-sale) in an open-market transaction, reducing her position by 5.1%. The stock currently trades at $131.62, up 3.2% over the past 30 days and 11.9% over 90 days. Across her same-ticker history at STT, her prior four sales have yielded mixed post-transaction outcomes: the three measurable 90-day periods show returns of +19.3%, +0.8%, and +19.0%, with none qualifying as well-timed (zero of three prior sales preceded declines). Her cross-ticker track record shows an average 90-day return of +13.0% after sells with a 0.00% well-timed rate, indicating her sale timing has not historically preceded share-price declines. The company reports a solid financial position with $3.5B quarterly revenue, $861.0M net income, and a P/E of 11.33.

EVP Horgan sells 5,676 STT shares at $118.55; holds 104,978 shares post-sale. Stock +2.9% (30d), -1.7% from 52wk high.

Kathryn M. Horgan, Executive Vice President of State Street Corp, executed an open-market sale of 5,676 shares at $118.55 on 2025-11-28, reducing her holdings from 110,654 to 104,978 shares. The stock currently trades at $119.02, only 1.7% below its 52-week high of $121.11, with positive recent momentum (+2.9% over 30 days, +5.3% over 90 days). Her prior sales at STT have historically failed to precede downturns: across three prior sales at this ticker, the average 90-day return was +13.0% (with two of three trades showing 90d gains of +19.3% and +19.0%), meaning she sold before price appreciations rather than declines. The transaction size is modest relative to her remaining stake, and occurs near the upper end of the stock's trading range, where historical insider timing at this ticker shows no pattern of well-timed exits.
