| Mar 13 | Earnings update | Neutral | +6.8% | Reported Q4/FY25 results, highlighting CAPTN-3 progress and cash runway into 2027. |

Recent news, especially around CAPTN-3 progress and corporate actions, has generally seen modestly positive or stable price reactions, with one notable divergence on positive preclinical data.
Over the last few months, Purple Biotech has focused investors on its CAPTN-3 tri-specific antibody platform while managing listing and leadership issues. A toxicology milestone for IM1240 on Jan 7, 2026 and positive ESMO IO 2025 data in Dec 2025 underscored pipeline progress. Corporate actions included an ADS ratio change announced on Feb 25, 2026 to address Nasdaq’s bid-price rule, and Q4/FY25 results plus a CEO transition on Mar 13, 2026. Today’s regained-compliance update follows directly from that ADS action, closing the loop on the listing risk highlighted earlier.
Market Pulse Summary
This announcement confirms that PPBT regained compliance with Nasdaq’s minimum bid-price rule by sustaining a $1.00+ closing bid for 10 consecutive days, resolving a previously disclosed listing risk tied to its ADS ratio change. It fits a broader narrative of shoring up capital-market access while advancing the CAPTN-3 platform and lead candidate IM1240 toward the clinic. Investors may track future updates on trial initiation timelines, funding plans, and leadership transition alongside ongoing regulatory filings and preclinical milestones.
