Earnings call summaries
Pick a quarter — each call distilled into takeaways, results, and a bull vs bear read.
Altimmune said Q2 was in line with expectations, with PERFORMA phase III in MASH now enrolling and RECLAIM data in AUD strengthening the case for a broader liver-disease franchise around pemvidutide.· August 12, 2026
- PERFORMA phase III in MASH has started enrolling globally, with about 300 sites planned and management saying activation is moving quickly.
- RECLAIM in AUD met its primary endpoint and key FDA-recognized secondary endpoints, including a 1.45 heavy drinking days per week treatment difference, about 2/3 achieving a 2-level WHO RDL reduction, and more than twice as many patients reaching 0 heavy drinking days versus placebo.
- Management highlighted additional signals beyond drinking, including a 9.1% weight reduction versus placebo and exploratory improvement in FIB-4 in patients above 1.3 at baseline.
- RESTORE in ALD finished enrollment, top-line data are expected in the second half of 2027, and the protocol was amended to assess liver stiffness at both week 48 and week 24.
- Cash was $519 million at June 30, 2026, and management said the runway funds the company through the MASH 52-week readout expected in 2029, but does not yet fund a potential AUD phase III.
Altimmune did not report revenue. Q2 2026 R&D expense was $18.7 million versus $17.2 million a year ago, driven by ALD trial investment and MASH phase III startup costs; Q2 2026 G&A was $7.6 million versus $5.7 million a year ago. Net loss was $22.8 million, or $0.12 per share, compared with a net loss of $22.1 million, or $0.27 per share in Q2 2025. For AUD, Christophe Arbet-Engels said pemvidutide 2.4 mg cut heavy drinking days versus placebo by 1.45 per week at week 24, about 2/3 of patients achieved a 2-level WHO RDL reduction versus 1/3 on placebo, more than twice as many achieved 0 heavy drinking days, and weight fell 9.1% versus placebo. June 30, 2026 cash was $519 million, and year-to-date the company raised approximately $310 million, including a $225 million follow-on offering in April. Forward-looking guidance: PERFORMA 52-week MASH readout is expected in 2029; RESTORE top-line ALD data are expected in the second half of 2027; management said a potential AUD phase III is not yet fully funded and would likely be financed with non-dilutive sources such as royalty, debt, or strategic partnerships after FDA/EU feedback on design and scope.
Jerry Durso said 2026 is a year of significant progress as Altimmune becomes a late-stage company focused on serious liver diseases. His tone was confident and upbeat, emphasizing speed of execution, the start of PERFORMA enrollment just three months after securing funding, and the strengthening evidence base for pemvidutide across MASH, AUD, and ALD. He framed the RECLAIM data as expanding the opportunity into a broader liver franchise and repeatedly stressed differentiation through the drug’s dual mechanism and focus on higher-risk patients.
Gregory Weaver said Q2 financials were in line with expectations. He gave specific figures: R&D was $18.7 million, G&A was $7.6 million, and net loss was $22.8 million, or $0.12 per share; June 30 cash was $519 million after about $310 million raised year-to-date, including the $225 million follow-on. He said that cash funds the company through the PERFORMA 52-week MASH readout in 2029, while a potential AUD phase III would need non-dilutive financing options such as royalty, debt, or partnerships once the regulatory path and study scope are clearer.
Analysts focused on MASH trial competition, ALD protocol changes, AUD phase III design, funding, and durability of the AUD effect. Management said PERFORMA’s 300-site global setup, site relationships, and design should help enrollment, and they expect the pace to be toward the lower end of a typical 18-to-24-month window. On AUD, they said one pivotal phase III may be sufficient under recent FDA guidance, they expect to align the primary endpoint with regulators, will broaden the population to include BMI below 25 and possibly ALD overlap patients, and are still working through the detailed timing and funding plan after the end-of-phase-II meeting.
The bull case from the call is that pemvidutide now has positive human data in two major programs, with AUD results showing not just drinking reductions but also weight loss and exploratory liver signals. Management sounded increasingly confident that the drug’s dual liver-and-drinking profile could differentiate it in moderate-to-severe AUD and ALD, while MASH remains on track with a large phase III study now underway. The balance sheet is also strong, with $519 million in cash and runway through the MASH readout.
The main risks are that AUD phase III is not yet designed, not yet funded, and still depends on feedback from FDA and European regulators. Management also acknowledged that RESTORE in ALD is being amended and will only read out in the second half of 2027, so the liver-benefit thesis still needs confirmation in longer-duration studies. In MASH, competition for sites and patients is real, and the company still has to prove enrollment speed and eventual efficacy in a crowded phase III landscape.

A “Sell” may be a pre-scheduled 10b5-1 plan sale rather than a discretionary decision — read insider selling with that in mind.
