$MCRB $XBI $IBB Looks like we're approaching a ~$40M market cap. @Cellsci, is this where you're buying, or are you still calling for more downside? Personally, I think the risk/reward is very compelling down here. ✅ No debt ✅ Cash runway into 2027 ✅ Breakthrough Therapy + Fast Track designations ✅ Strong SER-155 data ✅ Expansion into irEC with management engaging potential partners, including companies with ICI franchises ✅ Directors chose stock options instead of annual cash compensation, aligning themselves with shareholders

$MCRB $XBI $IBB Obviously because I'm invested and bullish on the stock. The better question is why you're still spending so much time bear-posting the $MCRB board if you supposedly sold a while back. Most people move on after they exit a position. Anyone who's done even a little homework on this company can understand why investors are very interested at a sub-$50M market cap. If you're still bearish at this valuation, I don't know what to tell you... maybe it's time to find a different hobby.

$MCRB If MSKCC and Seres can build a natural history cohort of Grade 2-3 irEC patients treated with standard-of-care corticosteroids, it could serve as external control for SER-155 Phase 2 registrational trials. We haven't heard about this in the July 8th meeting but Kelly mentioned in a previous meeting (see below). Kelly Brady's "modestly sized Phase 2" language is more consistent with single-arm external control design than randomized placebo comparison. This would materially change the SER-155 development pathway. Phase 2 could be single-arm with external control (~100 patients, 18-24 month execution), Breakthrough Therapy expanded to irEC, accelerated approval pathway targeted, potential BLA approval in 2030-2031 versus 2033-2034 under conventional pathway. Development costs decrease, time to market compresses by 3-4 years, and development risk decreases meaningfully. M&A economics under this framework would enhance meaningfully.

$MCRB https://clinicaltrials.gov/study/NCT06801067 still shows "Recruiting." As of the July 28, 2026 update, MSKCC/Faleck as the sponsor of record has not changed the status from "Recruiting" to "Active, not recruiting" or "Enrollment Closed." It could be one of two situations: - Bureaucratic lag. MSKCC could have completed enrollment months ago but simply hasn't gotten around to changing the status flag. But the July 28, 2026 update should have been the moment to fix this if it were pure lag. - The trial is actively enrolling additional patients beyond the original 15. This is the more interesting possibility. If MSKCC intentionally kept the "Recruiting" status because they're expanding the study — either adding a second cohort, adding more patients for statistical power, or continuing to enroll patients into a longer-term safety follow-up cohort — then the study we saw the July 8 readout from is not the complete study. Prevention, repeat-dosing, expanding cohort with a specific cancer, etc

$MCRB Still here. I didn’t think that they would take it this low, but Wall Street is accumulating on weakness and so will I. I’m still of firm belief that at or slightly above Nestle’s $21/share stake is where this will end up, and I’m hoping for a nice CVR on the back end. The irEC results reinforce that Seres is a platform and not a single asset / single indication company. Recent occurrences: - Nestle joining MTIG - Luis Briz Ordieres mentioning the microbiome as Nestle’s future beyond just GI conditions (e.g., immunology) in a recent podcast - Nestle buying the Seres milestones out, shows a continued dialogue and a working relationship between the two along with Evercore and Lazard as representatives - Many, many other things pointing that this relationship runs deep Have patience, and just remember how quickly they can move this stock. Also, do you really think that this company is worth less than $50M? Lol
