Significance 6/10

CEO Mainolfi sold 30,000 shares at blended avg $81.18 on 2026-04-29; prior 5 KYMR sales all declined 12.9%–16.4% in 30 days

Mainolfi executed 3 separate sales totaling 30,000 shares for $2,435,377.20 at prices between $80.74 and $82.45, representing a -4.3% reduction in his holdings to 666.2K shares. The timing context is notable: his prior 5 trades at KYMR (all on 2026-02-25) showed consistent 30-day declines ranging from -12.9% to -16.4%, suggesting a pattern of selling into strength at this ticker. The current stock price of $81.51 sits -14.2% below its 52-week high of $95.03 and recently gained +2.6% (30-day). However, the company fundamentals present headwinds: annual revenue contracted -16.7% year-over-year, the latest quarter posted only $2.8M in revenue against a $-82.2M net loss, and the company remains unprofitable. The near-term sales follow established pattern: after similar-sized exits two months prior, equity holders absorbed double-digit declines. This sale occurs against weak operational performance and a documented pattern of subsequent stock weakness at this company.

Significance 6/10

CEO Mainolfi sells 30,000 shares for $2.7M at blended $90.26 as stock nears 52-week high of $94.30

Nello Mainolfi, Kymera's Chief Executive Officer, executed 5 separate sales totaling 30,000 shares for $2,707,812.59 on February 25, 2026, reducing his holdings by 4.3% to 666,195 shares. The transactions occurred at prices ranging from $89.78 to $93.49, with a blended average of $90.26—just 3.8% below the 52-week high of $94.30. This is noteworthy given Kymera's deteriorating fundamentals: the company reported annual revenue growth of -40.1%, a latest-quarter revenue of $2,764,000.00, and a net loss of $-82,175,000.00 for the fiscal year. At the same time, the stock has surged +27.6% over 30 days and +33.6% over 90 days, creating a tension between price momentum and operational results. His prior trades at KYMR show a mixed timing pattern: two December 2025 and one October 2025 sales have each posted negative 30-day returns (-7.4%, -6.8%, -14.0%), while two October 2025 sales posted positive returns, yet 0 of 2 measurable 90-day outcomes were well-timed (the stock rose after those sales). The current sale occurs near the peak of a strong rally into structurally weak fundamentals.

$2,341,939
Significance 4/10

CEO Mainolfi sold 30,000 KYMR shares for $2.3M at $78.06 avg; holds 663.1K post-sale. Company posted -40.1% annual revenue decline.

Mainolfi executed 2 separate sales totaling 30,000 shares for $2,341,939.35, reducing his stake by 4.3%. The stock has risen 16.4% over the past 30 days and 39.0% over 90 days from trough, but remains 17.5% below its 52-week high of $94.30. Fundamentally, Kymera faces headwinds: annual revenue contracted 40.1% year-over-year to $2.8M in the latest quarter, and the company posted a $-82.2M net loss for its most recent full fiscal year. At the same ticker, Mainolfi's 5 prior trades show mixed timing: one measurable 90-day outcome (September 2025 sell) returned +74.9%, contradicting a well-timed pattern. The recent sales in December and late October occurred as the stock staged a rebound, offering no clear signal of foresight into either the near-term rally or the company's structural revenue decline.

Significance 6/10

CEO Mainolfi sold 100,000 shares at $89.17 for $8.9M; stock near 52-week high at $94.30 after +60.8% in 30 days.

CEO Nello Mainolfi sold 100.0K shares at $89.17, reducing holdings by 13.1% to 660.5K shares. The sale occurred at a price near the 52-week high of $94.30 (the filing records current price at $94.30, with the transaction at $89.17). The stock has surged +60.8% over the past 30 days and +116.9% over 90 days, placing the sale in a context of significant recent appreciation. At KYMR specifically, Mainolfi's prior four measurable sells all posted positive 30-day returns (+13.7%, +11.2%, +10.4%, +23.4%), with one of one prior sells at the 90-day mark showing a well-timed outcome (the June 2025 sale, which saw a -15.9% decline). The company faces fundamental headwinds: annual revenue contracted -40.1% year-over-year, the latest quarter posted only $2.8M in revenue against a -$82.2M net loss, and the enterprise remains unprofitable. This sale of a material block by the CEO follows an established pattern of regular dispositions at this ticker and occurs as the stock reaches elevated valuations.

Significance 5/10

CEO Mainolfi sells 30,000 KYMR shares (30.0K) for $1,829,736.92 in 3 transactions; holds 660.5K shares post-transaction.

Mainolfi executed 3 separate open-market sales totaling 30,000 shares for $1,829,736.92, reducing his holdings from 690.5K to 660.5K shares (-4.3%). The blended sale price of $60.99 sits 1.6% above the current price of $60.03, near the 52-week high of $62.89, against a backdrop of 37.2% gains over the past 90 days. At the same ticker, his prior sell on 2025-06-03 posted a -15.9% 90-day return (well-timed), but the company's fundamentals remain challenged: annual revenue contracted -40.1%, the latest quarter showed $11.5M revenue against a $-76.6M net loss, and the company has been unprofitable over its full fiscal year. The transaction occurs in a period of significant price appreciation, yet without visibility into his purchase history, settlement patterns, or personal liquidity needs, the sales alone do not establish a directional thesis about near-term stock performance.

Significance 6/10

CEO Nello Mainolfi sold 30,000 shares of KYMR at $49.00 on 2025-09-16; stock up 14.4% in 30 days but company posted -40.1% revenue decline.

Mainolfi sold 30,000 shares at $49.00, reducing his stake by 4.3% to 660,482 shares remaining. The sale occurred within a 14.4% 30-day rally and just 6.9% below the 52-week high of $52.40, suggesting the transaction executed during a period of upward momentum in the stock. His cross-ticker track record shows a 100.00% well-timed rate on prior sells, with the prior KYMR sale on 2025-06-03 also well-timed at the 90-day mark (both resulted in negative 90-day returns). However, the company's fundamentals present a sobering context: revenue contracted 40.1% year-over-year, the latest quarterly revenue stood at only $11.5M, and the company has sustained ongoing unprofitability with a -$76.6M net loss in the most recent period. The timing of this sale during a sharp rally, combined with the insider's demonstrated pattern of selling before subsequent declines at this exact ticker and the company's deteriorating financial trajectory, warrants investor scrutiny.

Significance 6/10

CEO Mainolfi sells 30,000 KYMR shares at $49.00; holds 660,482 post-sale as stock down 16.8% from 52-week high

Nello Mainolfi, Chief Executive Officer of Kymera Therapeutics, sold 30,000 shares at $49.00 on 2025-06-03, reducing his stake by -4.3% to 660,482 shares. The transaction occurred near the company's 52-week peak of $52.40, with the stock currently trading 16.8% below that high at $43.58. The context is material: Kymera reported Revenue $22,100,000.00 for the latest quarter against Net income $-65,581,000.00, with Annual revenue growth (FY vs prior FY) of -40.1%, reflecting significant operational headwinds. A CEO sale of material magnitude near cyclical peaks warrants investor attention, particularly given the company's sustained unprofitability and negative revenue trajectory.
