Case at review: Rising datacenter power density will increase the commercial content of rack-to-chip conversion and cooling suppliers, provided design wins become revenue without eroding margins.
MPS describes shipping power modules and contributions from optical-module and rack networking power solutions. This provides a commercial starting point beyond a generic efficiency narrative.
Horizon: 6–24 months; test socket conversion and margins at the next two quarterly reports.
Failure conditions: Named design wins are removed or fail to enter commercial shipment · Relevant revenue grows only through price concessions that erode margins across two reports
- Earlier on a named design win, design-out or material product-ramp change; verify supplier-specific economics.
AI power delivery: a licensing raise widens conversion; reported proof starts October 20

EOD 2026-10-06 campaign checkpoint (book-blind Opus review)
Hold, modestly strengthened and still bounded. Reviewed on the 2026-10-06 settled close against the standing condition (a named design win, design-out or material product-ramp change, verified with supplier-specific economics). The condition fired on Vicor: its September 21 release raised third-quarter sequential growth guidance from near 10% to over 20% on royalties from a new non-exclusive licence, with four OEM and hyperscaler licensees, and a further raise to over 30% was relayed on September 30 but is not on a filing. Conversion evidence now spans two suppliers instead of one. Neither failure condition has started: no named design was removed, and the incremental revenue is royalty-led rather than bought with price concessions. The countercase is equally specific: royalties are not module shipments, Monolithic Power's third-quarter figure is still a guide, Navitas is pre-scale (June-quarter revenue down 27.3% year over year) and Vertiv added capability by acquisition rather than proving content. On the 2026-10-06 tape, Monolithic Power (one year +52.22%, 14.3% above its 200-day), Vicor (+498.94%, 37% above) and Eaton (+17.12%, 14% above) hold intact long trends; Vertiv (+55.49% on the year) sits 4.7% below its 200-day and Navitas 9.7% below, so their long trends are under test. Rates were judged on September 30 to have little direct bearing on per-rack content. The two-report margin test the horizon names starts with Vicor on October 20 and Monolithic Power on October 29.

- Vicor third quarter (scheduled 2026-10-20): product revenue versus royalties; confirm the September 30 guidance raise on a filing; operating margin against the June quarter's 24.3%.
- Monolithic Power third quarter (scheduled 2026-10-29, after the close): revenue against the $1.14–1.16B guide, Enterprise Data mix, operating margin against 31.0%, and status of the tax-accounting material weakness.
- Vertiv third quarter (provider date 2026-10-21; one summary lists October 28 — confirm): organic growth separated from the UtilityInnovation and King acquisitions; the $14B sales outlook.
- Navitas (2026-11-02) and Eaton (2026-11-03) prints roll into the following review; Navitas needs revenue near the $13.0–14.0M guide before it counts toward conversion.
- Obtain a primary source for Vicor's September 21 release and the relayed September 30 raise so both can be linked directly rather than through the September 28 profile.
AI power delivery: Vicor's own patent case does not fire the licence trigger; reported proof still starts October 20
Campaign review · 2026-10-16 · data as of 2026-10-16
EOD 2026-10-16 checkpoint: licence-dispute clause checked, not fired as written (Vicor's own patent case); dated checks corrected from receipts
Hold. As of the October 16, 2026 settled close the case is undecided and unbroken, and the clause that prompted this early review did not fire as written. The trigger names a licence termination or dispute; the only dispute on record is one Vicor brought. Vicor's investor press room lists an October 12 announcement that the US International Trade Commission opened an investigation into vertical power delivery modules and computing systems alleged to infringe a Vicor patent. That comes from a summary of the press-room listing: the release and the Commission's notice have not been read, the respondents are not named in anything reviewed, and the item is single-source and secondary until they are. A patent complaint the company files neither ends nor contests an existing licence, and the clause sits among adverse triggers beside a design-out and a guidance cut, so Vicor's own enforcement does not meet it. It still bears on the royalty leg in both directions: enforcement is part of how Vicor turns its architecture into licences, while an adverse ruling or a costly case would weaken that leg. Neither failure condition has started: no named design was removed, and the margin-concession test cannot begin before the first report. Neither support has new reported evidence since October 6; the latest filed figures remain the June quarters (Monolithic Power operating margin 31.0%; Vicor 24.3%, with royalties 21.2% of revenue). Vicor fell 12.92% on October 16 to $191.50 on volume 1.81 times its average, against a 3.6% median decline in its AI power peer group that day; no news item, scheduled company event or filing on record explains it, so the cause is unknown, and price is not a test of this case. On that close all five names sat below their 200-day averages: Vicor 14.6% below but up 216.69% over one year (excess return +201.15 points), a long trend under test rather than broken; Monolithic Power 7.1% below, up 17.92%; Vertiv 23.1% below, up 16.08%; Eaton 0.7% below, up 4.17% with a one-year excess return of -11.36 points; Navitas 37.5% below and down 46.64%, a broken price trend consistent with the case already counting it as unconverted. The order of tests is unchanged: Vicor's third quarter on October 20 before the open (product revenue against royalties, whether the raise to over 30% appears in reported results, operating margin), Vertiv now expected October 28 (provider estimate, replacing October 21), Monolithic Power on October 29 after the close, then Navitas (provider estimate now November 3) and Eaton (November 3).

- Vicor third quarter (2026-10-20 before the open; provider calendar, and the company's investor page lists an 8:00 AM EDT call): product revenue versus royalties; whether the September 21 raise and the September 30 raise to over 30% appear in reported results; operating margin against the June quarter's 24.3%; any legal-cost line or respondent detail on the patent case.
- Capture Vicor's October 12 release and the Trade Commission's notices so the patent case can be linked from a primary source; record the respondents. If any respondent is another supplier this case follows, review before that supplier's report.
- Vicor's own investor overview now lists the September 30 guidance release, per a summary of that page; capture the release text to close the earlier primary-source gap.
- Vertiv third quarter (provider estimate 2026-10-28, observed October 15; the October 21 date is superseded): organic growth separated from the UtilityInnovation and King acquisitions; whether the $14B sales outlook holds.
- Monolithic Power third quarter (2026-10-29 after the close, per the company's release): revenue against the $1.14-1.16B guide, Enterprise Data mix, operating margin against 31.0%, and status of the tax-accounting material weakness.
- Navitas (provider estimate 2026-11-03, previously November 2) and Eaton (2026-11-03, provider calendar) roll into the following review. Read Navitas's October 6 8-K (the Claros merger closing, per its news summary) and Eaton's October 16 8-K first; separate any acquired Navitas revenue.
- Keep Vicor's October 15 and October 16 declines at cause unknown unless a dated receipt appears.
