$ALDX As a sub $300 mm mkt cap this will likely be removed from $XBI 06/19 Market makers and specialized algos have been prepping for that imo, getting short in order to capture a profit on the disgorgement of index and faux index holdings. Type A news and 13-G s also forthcoming. NIA

$ALDX 10-Q was out Thursday. They ran very lean Q1 & No ATM issuance effective 03/31/2026. Some fan boys will like that. Not selling treasury stock with price at 2.5 x book value ….I question that strategy. Nearly half a billion dollar cumulative deficit in this company . Doesn’t appear to be much to show for that level of investment. GL NIA

$ALDX shareholders can vote NO on the proposed compensation for the CEO/exec team. Giving him effectively options on 4% of the company is way too much reward for the multiple CRLs IMO.

$ALDX Okay, here’s the problem with ST as a DD resource. Our culture sort of dictates that for most participants that DD is not organic, ongoing for retail. That we just hear or see something, a narrative, an idea, a case and then we lock in. Join the club. This poster has no followers to speak of. He ran circles around Perceptive Advisors and others on this ticker. He has made all of his work public. His citizen’s petition arguably eased or illuminated the CRL path for FDA. He shared his work and his opinion freely BEFORE the CRL. He got ZERO likes on his post here. His posts on $ALDX have been pure gold. Suggestion. Learn “how to learn” about picking stocks. And if you find someone in bio who is this fluent in clinical trials. Follow them. 99% of us don’t understand the science and 50% of us busy telling each other how great the science is on some of these tickers. Think about that. GL PS Thank you @TripleGateCptl for generously putting your work into public domain at FDA, ST & X

$ALDX I just took note on yahoo finance that Perceptive Advisors sold 4,828,000 shares on April 3. They had previously reported owning 4,190,000 shares 12/31/25. I’ll assume that they are flat. NIA.

$ALDX Catalysts in my view are: 10-Q; shareholder call (they have yet to communicate with shareholders 7 wells after CRL #3); 13 G’s; Type A meeting results. Capitalization disclosure proforma any ATM share issuance in Q1 (signicant prints $4 + would be bullish imo, Median print prices would tend to put a cap on the SP imo). These 5 catalysts should all speak for themselves. If the company has a rabbit to pull out of its hat they are being extraordinarily patient in terms of showing any leg to shareholders.
