Super Micro names Mark Long CFO; the filing gives no reason

Super Micro changes CFO: David Weigand steps down and former Western Digital CFO Mark Long takes over immediately, with no reason given in the filing

Concept illustration in two side-by-side panels separated by a vertical double line. Each panel shows a green oval with blue lettering SUPERMICRO ending in a red dot, the black words SUPER MICRO below it, and under them a closed beige door. Each door has a white sign lettered CFO with a plain rectangular plate beneath it, grey-brown on the left door and red-orange on the right. Each door also has a lever handle on its left side and two hinges on its right edge.

Why it matters: Super Micro, a major AI server assembler, changes CFO with no reason given in the filing, so this issue draws no inference.

Super Micro filed on October 15 that its board appointed former Western Digital CFO Mark Long as CFO effective immediately on October 14, with David Weigand stepping down; the filing gives no reason and doesn't say where Weigand goes (Super Micro 8-K, 2026-10-15).

Answer check: Our July 31 call that the blended price on the official pricing page for Moonshot AI's Kimi K3 model would fall below US$0.50 per million tokens by October 15 missed. On October 15 the page's cached-input, input and output prices, weighted 7:2:1, blend to US$2.31 per million tokens, so Kimi K3's list price didn't move down as the call expected. Card →
