The author discusses $XFAB's ER, confirming its exposure to CPO and 800V shifts, with photonics volume production expected in 2028 and SiC design wins for 800V deployment. The thesis is validated despite current revenue not being impressive, and the stock may rerate as growth opportunities materialize.

For $XFAB ER transcript: Just to recap, my idea on $XFAB foundry growth opportunities stemmed from SiC for 800v and photonixfab/MTP for CPO applicability. - $XFAB: "We are making progress in co-packaged optics". - "The transition to 800v... is expected to support demand for both SiC and GaN... for XFAB" So those analysts/people that were confidently bearposting about $XFAB that they had "0 exposure to 800V, photonics, CPO" just turned out plainly wrong. At the time I shared my idea, industry materials showed ASE and others cited photonixfab + XFAB as an upcoming CPO player in EU. And filings showed they had exposure names like $NVTS / $POWI in general. So glad $XFAB went out to explicitly clear things up to state they were developing in CPO/800v. Okay back to the ER: - "We continue to expect photonics volume production to start in 2028". Company currently has three silicon photonics projects in development with key partners. I thought it would ramp sometime in H2 2027, but was probably early by a few months. - Several new data center design wins, eg. 3 new SiC design wins (consistent with general 2027 ramp as 800v deployment takes off). So once those ramp in 2027-2028, (markets tend to price things ahead of time), I'd expect $XFAB to be rerated based on growth opportunities. TLDR: - Current revenue numbers not as impressive. - $XFAB confirmed direct exposure to CPO and 800V shifts (biggest win for thesis) - 800V exposure opportunities for SiC (should be 2027) - Timeline is 2028 ramp for photonics volume production Happy exposure thesis to CPO/800V was confirmed from this ER. Might be a bit of waiting for revenue ramp.

Company explicitly confirmed exposure to co-packaged optics (CPO) and 800V transition, with multiple SiC design wins and photonics volume production planned for 2028. The author's thesis on growth opportunities is validated.
