Mike & Brent coin a new phrase in the context of white-collar corporate enforcement, “stack sweep,” to describe the potential enforcement risks–up and down the technology stack–that recent U.S. export controls settlements, policy statements, and guidance portend in focusing on broad end-use or end-user “catch-all” provisions that turn on “knowledge” defined to include “an awareness of a high probability.” Specifically, they discuss how two recent cases are short on facts but long on lessons (or, as Brent says, appear at first glance to be “dogs”) (01:07), discuss the Alpha & Omega Semiconductor (AOS) settlement announced July 2, 2025 (03:19), how reliance on the advice of counsel is as useful as the extent of facts disclosed to counsel (06:09), discuss the Unicat Catalyst Technologies settlement announced by the Bureau of Industry & Security (BIS) on June 24, 2025 and parallel settlements announced by the Department of the Treasury’s Office of Foreign Assets Control (OFAC) and the Department of Justice’s (DOJ’s) National Security Division (NSD) on June 16, 2025 (08:34), the lessons for pre-acquisition due diligence (11:03) including the importance to buyers of testing whether a target’s trade compliance program incorporates risks driving by the full definition of knowledge to include “high probability” awareness (for example, by specifically addressing risks under the catch-all provisions) (15:33), convergence across DOJ, Treasury, and Commerce regarding expectations for corporate compliance programs (17:50), and then Mike & Brent coin the phrase “stack sweep” to describe what would be the equivalent in corporate export controls enforcement to prior “industry sweeps” in corporate FCPA enforcement, in that catch-all, knowledge-driven end-use and end-user enforcement “sweeps” within the tech industry would be “sweeps” up and down the relevant technology stack (20:01). They then conclude with Brent’s back-by-popular-demand segment, “Managing Up” (25:52).
