The Expansion You Are Counting On Still Needs a Signature.
By Supply Signal | October 13, 2026 | 6 min read

This week, a conditional government loan commitment for domestic silicon carbide and gallium nitride production came with a checklist. One line of it is a customer's signature.
If a sourcing plan for 2027 or 2028 counts on that output, the plan now has dependencies that sit outside the supplier's factory. A second announcement covers silicon interposers for TSMC's CoWoS packaging under an initial five-year agreement, with the ramp expected to begin in the first half of 2028. And PC shipments fell by a fifth from a year ago, and some experts do not expect the situation to improve until 2029.
For a commodity manager, the work this week is continuity of supply. Find out which capacity in the plan is operating, which is funded, and which is still conditional.

The Loan Commitment Has a Checklist. One Line Is a Customer's Signature.
If your silicon carbide or gallium nitride plan assumes Wolfspeed's domestic buildout, treat that output as conditional. Wolfspeed disclosed a conditional commitment letter from the U.S. Department of War, acting through its Office of Strategic Capital, for a loan facility of up to $1.5 billion. The money is tied to a project with four parts: domestic silicon carbide wafer and power device production, domestic gallium nitride production, gallium-nitride-on-silicon-carbide epitaxial wafer technology for radio frequency parts, and domestic radiation-hardening capability. The terms of the project are still to be agreed.
The letter comes before the loan agreements, and Wolfspeed says it can give no assurance that it will negotiate and sign them.
The lender asks for customer documents before it signs. The conditions for signing include one or more letters of intent or definitive offtake agreements, on terms the lender accepts. Releases of funds after the first are conditioned on certain commercial arrangements, including offtake agreements, also on terms the lender accepts.
The releases also need a contribution from Wolfspeed. The company must bring at least $750 million of qualifying sources, received after June 28, 2026, or another amount the lender sets. Qualifying sources include new equity, excess cash and converted convertible debt. The $150 million for the first release must be new equity issued to third parties that are not affiliated with the U.S. government: $50 million before the facility takes effect, and $100 million that may come later but before the second release. The remaining $600 million can come from a wider set of sources, some at the lender's discretion.
For a buyer, I read the order this way. Wolfspeed needs customer letters or agreements before the loan is signed. The first release would refinance existing notes, and the later releases would fund the project. Without this financing, Wolfspeed says it may have to reduce the scope of its operations unless it obtains other financing. A buyer who waits for the capacity to appear may find its first output already promised to the customers who signed.
Other conditions include a definitive budget, amendments or waivers to existing debt, and the lender's own review, which it completes at its sole discretion. Wolfspeed must also make commercially reasonable efforts to convert a substantial majority of its convertible notes into equity. I treat each of these as a schedule risk, because any one of them can move the date on which a tool is ordered.

Five Years of Interposers for TSMC's CoWoS
If your product ships in a system that needs advanced packaging, keep this new U.S. output out of any schedule until the ramp begins. GlobalFoundries expects that in the first half of 2028. The company announced a manufacturing agreement with TSMC to supply silicon interposers for TSMC's CoWoS packaging from the United States. The agreement has an initial term of five years, and GlobalFoundries describes it as a $2 billion agreement. It will add capacity at its plant in Malta, New York.
Its forward-looking statements warn that planned expansions may not proceed as planned if funding the company expects to receive is delayed or withheld.
My reading: the announcement names one customer, so a system builder reaches this output through that customer's packaging allocation.

PC Makers Shipped a Fifth Fewer Machines
Plan memory on the long timeline. PC shipments fell 20.1% from a year earlier in the third quarter, a decline of 15.8 million units, according to IDC figures that Tom's Hardware reports.
Tom's Hardware gives two causes. Memory makers moved capacity toward the high-bandwidth memory that AI data centers buy, which left less capacity for consumer memory, and it reports memory prices up by as much as 500%. IDC's research director adds that vendors and channels loaded up on inventory in the first half of the year to get ahead of price increases.
The outlooks differ. Tom's Hardware reports that some experts do not expect the situation to improve until 2029, and that industry leaders, including Micron, say it will not improve for the next few years. Acer's chief executive expects PC prices to decline by the latter half of 2027 as Chinese memory capacity comes online.
I would plan a program that buys memory on the longer estimate. That means total cost of ownership and coverage assumptions that run through at least 2028.
Three Supplier Records to Update, One Assembly Site to Ask About
Update the approved-supplier record for three names, and confirm for each who now issues change notices and who supports the parts you buy. Navitas closed its merger with Claros on October 6. Microchip announced that it has acquired VORAGO Technologies, a provider of radiation-hardened and radiation-tolerant microcontrollers and microprocessors. Infineon announced that it has completed its acquisition of C2i Semiconductors, a firm that specializes in software-defined multiphase controllers and smart power stages for AI data center applications.
Rohm is expanding its use of outside assembly and test companies while it keeps wafer fabrication in-house, EE Times reports. In India, Rohm has announced partnerships with Tata Electronics for TOLL packages and with Suchi Semicon for TO-252 packages. The first products will be power MOSFETs, and the report says the aim is production for the local market before it potentially serves global demand. If you buy a Rohm power MOSFET in one of those packages, ask whether its assembly or test site will change and whether Rohm will issue a product change notice.
What to Watch For
I am watching four conditions on your behalf:
- Whether Wolfspeed reports signed loan agreements, or the first $50 million of new equity, in its next quarterly filing.
- Whether Wolfspeed names a customer, a product family or a volume in a letter of intent or an offtake agreement.
- Whether the first half of 2028 holds as the start of the GlobalFoundries ramp.
- Whether a memory maker names a date for improved supply.
What To Do This Week
- Document which silicon carbide and gallium nitride parts in each program depend on Wolfspeed wafers or devices, including parts bought from another device maker.
- Ask each silicon carbide and gallium nitride supplier whether it will seek a volume commitment from you, and on what terms.
- Add a status to every capacity announcement in a sourcing plan: operating, funded, or conditional.
- Keep U.S. interposer output out of any advanced-packaging schedule until GlobalFoundries reports that the ramp has begun.
- Model total cost of ownership through at least 2028 for each program that uses DRAM or NAND, with memory supply still constrained.
- Update the approved-supplier record for Navitas, Microchip and Infineon, and ask Rohm for the assembly and test site of each power MOSFET you buy in a TOLL or TO-252 package.
Wolfspeed's new output carries a financing and schedule risk until the loan, with its customer letters or agreements, is signed or other financing is in place. GlobalFoundries' new output waits on a ramp that it expects in the first half of 2028. Mark both as conditional until a supplier gives you a date and a quantity.
