## About

The Siltronic Corporation Pension Plan was created in 1968 to provide retirement security for employees of the US arm of Siltronic AG, the Munich-headquartered silicon-wafer manufacturer that supplies semiconductor giants including TSMC, Intel, and Samsung. The plan is a noncontributory defined-benefit arrangement, meaning the employer bears the full funding obligation. It covers Siltronic's United States workforce, centered on its Portland, Oregon production facility on Front Avenue. The plan's parent, Siltronic AG, remains a publicly traded entity with a concentrated shareholder base: the founding family's vehicle, Dr. Alexander Wacker Familiengesellschaft mbH, holds a 30.83% stake, Dutch investment company HAL Investments holds roughly 15.1%, and Taiwanese wafer rival GlobalWafers owns approximately 9.5% after a 2022 takeover bid for the whole group collapsed under German regulatory pressure. The plan deploys capital across a broad mandate spanning buyout, early-stage venture — from seed through startup and expansion stages — and fund-of-funds commitments. No individually named portfolio companies are publicly disclosed, consistent with the plan's private, single-sponsor structure. Geographic reach is concentrated in North America, aligned with its participant base. Total assets are not publicly disclosed by the plan. Altss research estimates approximately $105 million in plan assets, placing it in the smaller tier of corporate pension funds. The plan's sponsor, Siltronic AG, operates production sites in Burghausen and Freiberg in Germany, Singapore, and Portland, Oregon, with its corporate headquarters in Munich. The plan itself is administered from Portland. A modest philanthropic arm, the Siltronic Cent Donation Program, operates separately from the pension vehicle. What distinguishes the Siltronic Corporation Pension Plan is its position inside a critical but geopolitically fraught supply chain. Its sponsor is one of only five global manufacturers of 300mm silicon wafers, a market shaped by export controls, subsidized competition from China, and the failed GlobalWafers acquisition. The pension plan sits adjacent to a company where ownership and operational control intersect with German industrial policy and Taiwanese semiconductor ambitions — a structural context that shapes every long-term capital decision the plan makes.

## Questions

The plan covers US employees of Siltronic Corporation, the American subsidiary of Munich-based Siltronic AG. The parent company is listed on the Frankfurt Stock Exchange and is 30.83% controlled by the Wacker family holding company, with additional large stakes held by HAL Investments (about 15.1%) and GlobalWafers (about 9.5%). The plan is a separate legal entity, its assets protected from the sponsor's creditors under ERISA.

### What regulatory environment governs the plan?

As a US corporate defined-benefit plan, it is governed by ERISA, which imposes fiduciary duties, funding requirements, and reporting obligations. The plan files IRS Form 5500 annually, though those filings are not publicly analyzed in this profile.
