​ ​ Item 2.02 Results of Operations and Financial Condition On March 27, 2024, Altimmune, Inc. (the “Company”) issued a press release announcing the Company’s financial results for its full year and fiscal quarter ended December 31, 2023. A copy of this press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K. The information included in this Current Report on Form 8-K (including Exhibit 99.1 hereto) that is furnished pursuant to this Item 2.02 shall not be deemed to be “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that Section or Sections 11 and 12(a)(2) of the Securities Act of 1933, as amended.

Item 8.01 Other Events On March 27, 2024, the Company announced results of the body composition analysis from its 48-week MOMENTUM Phase 2 obesity trial of pemvidutide. As announced on November 30, 2023, the trial enrolled 391 subjects with obesity or overweight with at least one co-morbidity and without diabetes. Subjects were randomized 1:1:1:1 to 1.2 mg, 1.8 mg, 2.4 mg pemvidutide or placebo administered weekly for 48 weeks in conjunction with diet and exercise. The 1.2 mg and 1.8 mg doses were administered without dose titration, while a short 4-week titration period was employed for the 2.4 mg dose. At baseline, subjects had a mean age of approximately 50 years, mean body mass index (BMI) of approximately 37 kg/m2 and mean body weight of approximately 104 kg. Approximately 75% of subjects were female. The body composition analysis showed that 74.5% of weight loss was derived from adipose tissue and only 25.5% from lean mass, comparable to the effects historically associated with weight loss from diet and exercise programs.

About Altimmune Inc. (ALT) Earnings

This page provides Altimmune Inc. (ALT) earnings call transcripts from SEC 8-K filings along with AI-powered predictions for post-earnings price movements. Our machine learning models analyze historical earnings data, pre-earnings price patterns, volume changes, and volatility to predict 1-day, 5-day, and 20-day returns after each earnings release.

Earnings transcripts are sourced directly from SEC EDGAR filings. Predictions are generated using gradient boosting models trained on ALT's historical earnings reactions. All predicted returns are shown as percentages, and predicted prices are calculated from the closing price at the time of prediction. Past performance does not guarantee future results.
