MultiLane Test Products (MLTP) builds test and measurement instruments for the very high speed electrical connections inside data centre equipment, including bit error rate testers and time domain reflectometers used to validate interconnects running at 224 gigabits per lane and beyond. It was formed in 2026 as a joint venture between the semiconductor test equipment maker Teradyne, which takes the majority stake and brings its global electronics test sales and service reach, and MultiLane, a Lebanon based high speed instrumentation specialist that contributed all of the assets of its test and measurement business while keeping its separate interconnect and data centre product lines. The venture targets the AI data centre supply chain, covering test needs from wafer level through to installed systems.

MultiLane Test Products Holding LLP (MLTP) files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from Teradyne and MultiLane Announce Formation of Joint Venture, MultiLane Test Products (Teradyne investor relations), MultiLane Test Products: A Joint Venture Between MultiLane and Teradyne (ECOC exhibition news) and Teradyne, MultiLane Announce Formation of Joint Venture, MultiLane Test Products (I-Connect007). The ownership figures below come from the holders' filings instead, and are sourced row by row.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.
- Teradyne, Inc., as of 8 Apr 2026. On 8 Apr 2026 Teradyne and HTP Holding SAL ('MultiLane') formed MLTP, a joint venture, to which MultiLane contributed the assets of its test and measurement business. Teradyne holds a controlling 75% ownership interest and consolidates MLTP; the remaining 25% is a genuine third-party noncontrolling interest held by HTP Holding SAL, not a wholly owned subsidiary. It is listed here as a holding, following the Nucor/Moody's ICRA precedent for a consolidated entity with a real minority third party, rather than excluded as a wholly owned subsidiary. Total purchase price for the transaction was approximately $157.8 million, subject to customary post-closing adjustments, per Teradyne's Q2 2026 10-Q Note D ('Acquisitions'); that figure is used as value_usd. Teradyne's condensed consolidated balance sheet at 28 Jun 2026 separately reports 'Equity attributable to noncontrolling interests' of $36.151 million, which is HTP Holding SAL's 25% share of MLTP's consolidated net assets as of that date, a different figure from the transaction purchase price and not substituted for it. LLP ownership is not share-denominated, so shares is null. source
What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of MultiLane Test Products Holding LLP (MLTP) where a holder stated one, and are missing where no holder did.
