Read MoreHide Full Article

Armata Pharmaceuticals, Inc. (ARMP - Free Report) shares ended the last trading session 103.2% higher at $7.05. The jump came on an impressive volume with a higher-than-average number of shares changing hands in the session. This compares to the stock's 13.8% gain over the past four weeks.

The massive stock price surge was observed after the company reported positive mid-stage results for its investigational bacteriophage therapy, AP-SA02, targeting Staphylococcus aureus bacteremia (SAB). The late-breaking data, presented at IDWeek 2025, demonstrated significantly higher cure rates and zero relapse among patients treated with AP-SA02 in combination with standard antibiotic therapy, compared to placebo. The treatment also showed a favorable safety profile with no serious drug-related adverse events. Importantly, the study marked the first randomized clinical study to confirm the efficacy of intravenous phage therapy for S. aureus infections, highlighting its potential as a novel approach against antibiotic-resistant bacteria. The findings reinforce Armata’s plan to advance AP-SA02 into a pivotal phase III study in 2026, pending alignment with the FDA, fueling investor optimism over the company’s leadership in next-generation antibacterial therapeutics.

This company is expected to post quarterly loss of $0.42 per share in its upcoming report, which represents a year-over-year change of -180%. Revenues are expected to be $1.38 million, down 53.5% from the year-ago quarter.

Earnings and revenue growth expectations certainly give a good sense of the potential strength in a stock, but empirical research shows that trends in earnings estimate revisions are strongly correlated with near-term stock price movements.

For Armata Pharmaceuticals, the consensus EPS estimate for the quarter has remained unchanged over the last 30 days. And a stock's price usually doesn't keep moving higher in the absence of any trend in earnings estimate revisions. So, make sure to keep an eye on ARMP going forward to see if this recent jump can turn into more strength down the road.
