| /research/economics | H1 revenue was $1,459.389M, gross profit $1,065.940M and GAAP operating income $3.596M. Atlas represented a rounded 74% of H1 revenue and 73% of Q2, so the model labels derived Atlas dollars as proxies. Q2 GAAP operating profit of $28.4M contrasts with the Q3 $10.5M-$14.5M loss outlook. H1 CFO of $343.509M included $286.769M SBC; receivables provided $43.695M while deferred revenue used $24.183M. PP&E of $4.791M and finance-lease principal of $3.554M yield company FCF of $335.164M. Subtracting $117.673M award withholding leaves $217.491M, before $200.254M repurchases. Unrestricted cash and securities totaled $2,411.254M, with $3.411M restricted separately. RPO of $1,519.2M and cRPO of $797.3M are not an exhaustive consumption forecast. | H1 revenue was $1,459.389M, gross profit $1,065.940M and GAAP operating income $3.596M.

On September 28 the company reported that chief executive Chirantan Desai resigned effective that day to take a senior role at Meta Platforms, and that Dev Ittycheria, chief executive from September 2014 to November 2025 and still a director, became interim president and chief executive under his existing October 29, 2025 advisory agreement while a retained search firm seeks a permanent successor. The same release reaffirmed the September 1 third-quarter guide of $756M-$761M revenue and $1.57-$1.61 non-GAAP EPS and the fiscal 2027 guide of $2.99B-$3.03B revenue and $6.39-$6.58 non-GAAP EPS, and kept the September 29 investor day. No revenue, margin, cash or share input in this model changed; the transition is a leadership and execution variable, not a demand print. |
| /research/limitations/6 | None | The September 28 chief executive transition changes no modeled input. The third-quarter and fiscal 2027 guidance reaffirmed that day are the same figures used to calibrate this model; no interim-leadership discount or premium is applied to demand, margins or cash, and the operating-model cells are unchanged from the September 19 review. |
| /research/reviewed_at | 2026-09-19 | 2026-09-28 |
| /research/risks/6 | None | Chief executive transition: an interim leader, a search of undetermined length and the departure of the executive who set the fiscal 2027 plan can affect hiring, sales execution and product timing without changing the stated guide. |
