Cloudflare's Zatlyn Exercises and Sells $5.4M in NET Stock

On May 27, 2026, Michelle Zatlyn — co-founder, President, and Board Co-Chair of Cloudflare — did something that looks dramatic on a transaction ticker and is almost mechanical underneath: she exercised 25,641 stock options and, in the same session, sold an identical 25,641-share block of NET for roughly $5.4 million. The sales printed across a tight band from about $208.45 to $213.25, a VWAP near $209. To a scanner watching only Form 4 Table I, the line that follows is the one that misleads: Class A shares owned after the transaction fell to 25,641, and the conversion leg shows a zero. Read in isolation, it reads like an exit. It is not.

The differentiated fact here is the share class structure, and it changes the whole story. Zatlyn's transaction was a cashless exercise-and-sell — she converted options into stock and immediately monetized the same quantity, the signature of a prearranged exercise program rather than a discretionary call on the stock. More importantly, the Form 4 (accession number 0001786951-26-000008) shows she still holds roughly 1.36 million shares through derivative and indirect positions reported in Table II. The President of Cloudflare did not walk away from the company she helped build; she harvested a vested option tranche and kept the overwhelming majority of her economic stake intact.

Why the timing looks better than it was

The headline temptation is the calendar. Zatlyn sold on May 27. The next day, NET rose about 8%; the day after that, it added another 6%. Sell low, watch it rip — except that framing assumes she chose the date, and the exercise-and-sell structure argues she did not. Cashless exercises are typically triggered by option vesting schedules or a Rule 10b5-1 trading plan adopted months earlier, which means the May 27 print was set in motion long before the late-May rally. The cleaner read is that an automated program crossed paths with a good week for the stock, not that an insider mistimed a bearish bet.

What drove the rally matters for context. Cloudflare reported Q1 2026 revenue of $639.8 million, up 34% year over year, beating estimates and lifting full-year guidance toward the $2.80–$2.81 billion range, with Q2 revenue guided to roughly $664–$665 million. The company is leaning hard into an "AI-first" posture — its Workers AI and AI Gateway products, plus a high-profile tie-up to run Anthropic's Claude managed agents on Cloudflare's network — and that narrative is what investors rewarded into the end of the month. The same restructuring story carries a sharper edge: Cloudflare also signaled a roughly 20% workforce reduction with $140–$150 million in associated charges, a cost reset that the market chose to read as margin discipline rather than weakness.

The ownership picture, stated correctly

Here is the part that separates a data-rich read from a transaction rehash. After May 27, Zatlyn's directly held Class A position sits at 25,641 shares per Form 4 Table I, with about 1.36 million additional shares held via derivative and indirect structures in Table II. She is not, on the latest filing, a greater-than-5% beneficial owner of Cloudflare. That distinction belongs to co-founder and CEO Matthew Prince, whose most recent Schedule 13G reported a 7.7% stake — roughly 26.3 million shares — making him by far the largest insider holder and the controlling founder voice on the cap table.

The institutional register around them is genuinely active money, not just index plumbing. Cloudflare's largest 13F holder is Capital World Investors, the Capital Group active arm, near $4.7 billion of reported NET value, with sibling fund Capital International Investors holding another ~$2.2 billion. Growth specialist Baillie Gifford remains a top-five holder at roughly $3.3 billion and has filed 13Gs above 5% in the past, while Morgan Stanley and FMR LLC (Fidelity) round out the conviction-weighted names. Index vehicles like BlackRock's iShares complex and Vanguard sit high on the value table too, but those positions reflect benchmark weight, not a view — worth separating before anyone calls the whole holder base "smart money."

What to actually watch next

Forward markers, not vibes. The next scheduled catalyst for NET is Q2 2026 results, due in early August 2026, where the test is whether the company hits its $664–$665 million revenue guide and shows the restructuring charges flowing through without denting the AI-product momentum. On the insider side, the thing to track is not whether Zatlyn sold once — it is the cadence: if her exercise-and-sell prints recur on a roughly monthly or quarterly rhythm at similar share counts, that confirms a plan-driven program and removes any signal value from individual sales. A break in that cadence, or a discretionary open-market sale outside the option mechanics, would be the line worth flagging.

FAQ

Did Michelle Zatlyn sell all her Cloudflare shares? No. She sold 25,641 Class A shares for about $5.4 million on May 27, 2026, but retains roughly 1.36 million shares through derivative and indirect holdings reported in Form 4 Table II, and remains Cloudflare's President and Board Co-Chair.

Why did Zatlyn sell NET right before the stock rallied? The sale was a cashless exercise-and-sell — she exercised 25,641 options and sold the same quantity the same day — which is characteristic of a prearranged option or Rule 10b5-1 program set months in advance, not a discretionary trade timed to the rally that followed on May 28–29.

Who is Cloudflare's largest insider shareholder? Co-founder and CEO Matthew Prince, whose most recent Schedule 13G reported a 7.7% stake of roughly 26.3 million shares — far larger than Zatlyn's direct position.

When is Cloudflare's next earnings report? Q2 2026 results are expected in early August 2026, the next scheduled test of the company's $664–$665 million revenue guidance and its 20% restructuring plan.
