Michelle Zatlyn (President, Board Co-Chair) sold 99,064 shares for $27,419,061.29 via scheduled 10b5-1 plan, reducing common holdings 67.6%.

Michelle Zatlyn executed 26 separate sales totaling 99,064 shares for $27,419,061.29 across 2026-07-13 to 2026-07-15, reducing her non-derivative holdings from 146,489 shares to 47,425 shares. This transaction is part of a pre-arranged 10b5-1 trading plan adopted on 2026-02-27, meaning the sales were scheduled rather than discretionary. The sales occurred as NET's stock traded near its 52-week high of $291.00, currently at $273.04. Zatlyn retains significant equity exposure through derivative securities including 1,254,114 employee stock options and 1,221,111 additional options across multiple tranches. While the company achieved 29.8% annual revenue growth, it reported a net loss of $-22,927,000.00 in its most recent full fiscal year, which provides context for evaluating this scheduled divestiture by a president-level executive.

Director Carl Ledbetter sold 5,000 NET shares at $268.11 under 10b5-1 plan; retains 888,073 shares post-sale

Carl Ledbetter executed a sale of 5,000 shares (5.0K shares) on 2026-07-07 at $268.11 per share, reducing his holdings to 888,073 shares (-0.6% vs pre-transaction holdings). The sale is part of a pre-arranged 10b5-1 trading plan adopted on 2026-02-25, making this a scheduled transaction rather than a discretionary decision. Over his cross-ticker open-market history, his prior 20 sells have posted an average 90-day return of +0.8%, though his same-ticker history at NET shows recent sales on 2026-06-01 with measured 30-day returns ranging from -0.8% to +1.0%. The company reported revenue of $639,755,000.00 in the latest quarter with annual revenue growth of +29.8%, but remains unprofitable with full-year net income of $-22,927,000.00, a context that differs meaningfully from his recent trading pace at this ticker.

Cloudflare CEO Matthew Prince completes 23 scheduled sales totaling 86,014 shares for $21,099,988.17 via pre-arranged 10b5-1 plan

Matthew Prince executed 23 separate sales totaling 86,014 shares for $21,099,988.17 across July 2–6, 2026 at prices ranging from $239.64 to $250.39, with a blended average of $245.31. This transaction was part of a pre-arranged 10b5-1 trading plan adopted on 2026-02-26, meaning the sales were scheduled and non-discretionary. While the non-derivative holdings post-transaction show zero shares, Prince maintains substantial derivative holdings of 9,975,371 Class B Common Stock shares across three ownership vehicles, indicating his position in the company continues materially. The company remains unprofitable on a full-year basis (net income of $-22,927,000.00), though revenue grew 29.8% year-over-year to $639,755,000.00 in the latest quarter. Because this activity is governed by a scheduled 10b5-1 plan, the execution reflects predetermined parameters rather than current discretionary market judgment.

Matthew Prince executed 25 separate sales totaling 71,174 shares for $17,600,256.43 at a blended average price of $247.28, all via a pre-arranged 10b5-1 trading plan adopted on 2026-02-26. The sales span two trading days (2026-07-01 and 2026-07-02) across a narrow price range ($239.84–$252.14), consistent with scheduled algorithmic execution rather than discretionary timing. Post-transaction, Prince retains derivative holdings of 11,454,202 Class B shares across three ownership vehicles, meaning his economic interest in the company remains substantial. Cloudflare reported revenue of $639,755,000.00 for the latest quarter and annual revenue growth of +29.8% year-over-year, though the company remains unprofitable with net income of $-22,927,000.00 over its most recent full fiscal year.

This filing is part of a pre-arranged 10b5-1 trading plan adopted on 2025-02-11, meaning the sales were scheduled and not discretionary. While Prince's non-derivative holdings fell to zero, he retains 4,296,167 Class B Common Stock shares as derivative holdings, so this represents a scheduled reduction of a specific batch rather than a complete position exit. Prior trades by Prince at Cloudflare show positive outcomes over a 30-day horizon (ranging from +5.6% to +8.0% across 5 recent sales on 2026-05-21), consistent with his cross-ticker track record average of +8.0% over 30 days. The company reported annual revenue growth of +29.8% against the latest quarter revenue of $639,755,000, but remains unprofitable with a full-year net income of $-22,927,000, reflecting an early-stage profitable-trajectory tension in the business.

CEO Matthew Prince sold 104,768 shares for $23,221,887.48 on 2026-06-22/23 under 10b5-1 plan; retains 8,749,486 derivative holdings.

Post-transaction, his non-derivative holdings are zero; however, his derivative holdings total 8,749,486 shares across two Class B ownership vehicles, meaning his economic stake in the company remains substantial. Cloudflare is currently unprofitable (net income $-22,927,000.00 on $639,755,000.00 revenue) and the company is up 3.4% over 30 days and +6.4% over 90 days, placing the stock 19.3% below its 52-week high of $276.82.

However, significant derivative holdings remain across the filing: 1,338,454 employee stock option shares, 1,312,813 employee stock option shares, 1,287,172 employee stock option shares, and three separate tranches of 25,641 Class B common shares, totaling 4,015,362 shares in derivative securities, indicating the insider's overall economic position in the company remains substantial. As a scheduled trade under a 10b5-1 plan rather than a discretionary transaction, this sale reflects pre-planned capital allocation rather than a current judgment about valuation; investors should note the company reported $-22.9M net loss on $639.8M revenue in the latest quarter, though annual revenue growth was +29.8%.
