Sentiment Analysis:

Overall Tone: Positive

• CEO stated 'We are looking good for Stage C, but we can't make any promises. But I would say that we're hitting everything we need to, and it's looking good.' CFO reported increased headcount and tape-outs, with significant growth expected in the second half. Management highlighted progress on optical loss reduction and partnerships, emphasizing long-term mission and confidence in roadmap.

Q&A:

• Question from Tanuti Yohan (Rosenblatt): You had published results on edge coupling losses, and you spoke about them today, too. Can you talk a little bit about the 16 other components that you were engineering to minimize losses?
  Response: Management identified 16-17 major components where loss reduction is critical, including beam splitters, phase shifters, ring resonators, and detectors, and noted architectural simplifications like reducing the number of beam splitters.

• Question from Kingsley Crane (Canaccord Genuity): I just wanted to check in on project optimism and just if there was any update there on potential to secure that funding or the timing around that or just any incremental understanding of the milestones there.
  Response: Management stated the project is in 'final discussions now,' with hopes to have more information in the next month or two.

• Question from Kingsley Crane (Canaccord Genuity): And then maybe just on the joint QML and workforce training that you're doing with Lockheed Martin, I'm kind of just curious. how they came about, how excited you are about the program, and then potential to evangelize Penny Lane, but also just quantum computing in general.
  Response: Management expressed excitement, noting Lockheed Martin is a longtime user of Penny Lane; the program aims to democratize quantum algorithm development by leveraging Xanadu's platform and educational resources to train engineers.

• Question from Nihal Chokshi (Northland Capital Markets): You know, R&D engineers, R&D talent is... to achieving this 2030 objective. Has this talent pipeline for R&D engineers changed materially since becoming public?
  Response: Management stated the talent pipeline has improved positively due to increased awareness, ability to offer RSUs, and liquidity, leading to a larger pool of applicants and better hires.

• Question from Nihal Chokshi (Northland Capital Markets): And then my last question is that in your press release, you mentioned a seminal Penny Lane paper that's been cited 2,000 times. When was the seminal Penny Lane paper actually published?
  Response: The paper was first published on the archive around eight years ago, with formal publication about a year later, and has been generating citations since.

• Question from Todd Coupland (CIBC): I was wondering if you could comment on the optical loss performance so far and rank that, I guess, against DARPA-C expectations and include in that an update on where you think you might get by year-end when you expect an announcement on that.
  Response: Management stated performance is looking good for DARPA Stage C, with the loss gap decreasing 200 times over four years and a 5-10 times reduction remaining to reach fault tolerance, on track for the roadmap.

• Question from Todd Coupland (CIBC): And then my second question, it has to do with OpEx and CapEx growth expected in the second half of the year. How should that look versus what you just reported?
  Response: Management expects OpEx and CapEx to increase significantly in the second half due to added engineering talent and increased tape-outs, with more details to be provided at the analyst day.

• Question from Paul Treiber (RBC Capital Markets): In regards to the FAB runs, you mentioned the 50% increase and 75% increase. What's the current run rate for the annual FAB runs? And then what's the magnitude of increase that you expect from current levels?
  Response: Management stated the silicon nitride foundry run increased from ~100 to 150 wafers (a 50% increase) and expects further increases, while the silicon nitride run is at ~175 wafers per month and also expected to grow.

Okay, let's see. The user wants me to rewrite the input into a concise earnings-call question. The input is "Has the R&D engineering talent pipeline changed materially since going public?" First, I need to make sure I follow the rules. The output must be exactly one line, only the final question text, end with a question mark if possible. No explanations or anything else. If the input isn't a question or is too vague, output it as-is.The original input is a question, so I can rewrite it. The key elements here are R&D engineering talent pipeline, changed materially, and since going public. The user is asking if there's been a significant change in the talent pipeline after the company went public.I need to make it concise. "Materially" is already a strong term, so maybe that's okay. "Changed materially" is good. The phrase "since going public" is clear. Maybe "R&D engineering talent pipeline" can be shortened? Perhaps "R&D talent pipeline" is sufficient, as engineering is part of R&D. Let me check if that's acceptable. If the original mentions engineering, maybe it's better to keep it for specificity. But maybe the user wants it as concise as possible. Let me see.Original: "Has the R&D engineering talent pipeline changed materially since going public?"Possible rewrite: "Has the R&D engineering talent pipeline changed significantly since the company went public?" But the original says "materially," which is a term often used in financial contexts. Maybe "materially" is better to keep for accuracy. Also, "since going public" is concise. Wait, "since going public" could be "post-IPO" but that might assume the company went public via an IPO. The original uses "going public," which is more general. So maybe keep "since going public."Is there a way to make it shorter without losing meaning? Maybe "Has the R&D engineering talent pipeline changed materially since the company went public?" That's slightly longer but more explicit. But the original didn't include "the company," so maybe that's unnecessary. The original is "Has the R&D engineering talent pipeline changed materially since going public?" That's already pretty concise. Maybe that's the best version. It's a clear, concise question ending with a question mark. I don't see a need to change it further. So the answer would be the same as the input, but maybe the user wants it rephrased. Wait, the instruction says to output exactly one line, only the final question text. If the input is already a clear question, maybe the answer is the same as the input. Wait, but the user says "rewrite the input into ONE concise earnings-call question." So maybe the input is already a valid question, but perhaps they want it to be more concise. Let me check.Original: "Has the R&D engineering talent pipeline changed materially since going public?" Is there a way to make it more concise? Maybe remove "engineering" if it's implied by R&D. But R&D can include other areas. However, the user specified "engineering talent pipeline," so maybe it's better to keep it. Alternatively, "R&D talent pipeline" might be sufficient if engineering is part of R&D. But the original includes "engineering," so perhaps keeping it is better for accuracy. I think the original is already concise enough. Therefore, the output should be the same as the input. Wait, but the user says if the input is already a clear question, output it as-is. Wait no, the instruction says: "If the input is NOT a question, is too vague, or lacks enough information to form a clear earnings-call question, output the input EXACTLY as-is, with no modification." Since the input is a clear question, we need to rewrite it into a concise one. Wait, but maybe the input is already concise. Let me check again. The user wants it rewritten into one concise question. So if the input is already a concise question, then output it as is. But maybe the input can be made more concise. Alternatively, maybe the answer is "Has the R&D engineering talent pipeline changed materially since the company went public?" which adds "the company" for clarity. But the original didn't have that. Hmm. Alternatively, "Has there been a material change in the R&D engineering talent pipeline since going public?" That's slightly different structure but more concise. However, the original uses "changed materially," which is active voice. Maybe that's better. I think the original is already a valid, concise earnings-call question. Therefore, according to the rules, if it's a clear question, we should output it as is. Wait, no, the instruction says that if it's a clear question, we need to rewrite it. Wait, no. The instruction says: if the input is NOT a question, is too vague, or lacks info, output as-is. Otherwise, - Tyler Anderson (Craig-Hallum Capital Group)

2026Q1: The company’s reputation and hiring have benefited from going public, but existing customer and partnership discussions have not fundamentally changed. Large corporations that were already engaged continue to collaborate. - [Dr. Christian Weedbrook](CEO)
