In a surprising number of Taipei IC packs, “synergy” is still a single stacked bar: procurement, footprint, and people, added as if they shared a clock. The board nods because the story is familiar. The problem arrives six months later, when the SPA’s schedule has to say which of those bars was a hope and which was a contracted effort.
Procurement savings are the easiest to over-claim. A Taiwanese buyer with a strong vendor list looks at a target in Vietnam and writes “harmonise suppliers.” That sentence hides three questions: whether the target’s customers will accept a change of component source, whether the saving is gross or net of dual-sourcing during transition, and whether anyone has spoken to the vendor who currently enjoys a related-party volume. M&A Advisory Consulting work that stops at the stacked bar is not analysis. It is a mood.
Footprint claims are slower and more honest when they are ugly. Closing a line in Taoyuan to move volume to a cheaper site sounds like arithmetic until you put the severance calendar next to the customer qualification calendar. Boards dislike that slide because it looks like delay. Delay is the point. If the qualification window is fourteen months, the year-one synergy number in the CIM is a literary device.
Headcount efficiency is where Taiwanese rooms go quiet. Family shareholding, long-tenured plant managers, and the social cost of a public listed buyer “cleaning up” a company it just praised in a press release all sit on the same page. Advisers who write “15% overhead reduction” without naming whose overhead are doing the board a disservice. In studio we make students split the claim into roles that turn over naturally, roles that require a plan, and roles that will not move without a fight they have not budgeted.
None of this means synergies are fake. It means the board pack should carry the same grain as the later disclosure schedules: owners, timing, and the sentence you are willing to say when the number misses. If you cannot write that sentence in English for a cross-border call, the Chinese version in the IC pack is probably doing decorative work.
