Aprea Therapeutics reported a third-quarter 2026 net loss of $4.81 million, up from $2.97 million a year earlier, even as its per-share loss narrowed. The quarter ended Sept. 30, and the company has not yet commercialized any product candidates.

Why it matters

A larger total loss paired with a smaller per-share loss shows how share issuance can change the reading of a clinical-stage company's results. For operators, the figures are a reminder to look at share count and funding runway alongside headline loss when evaluating early-stage partners or vendors.

Aprea's Q3 2026 net loss rose to $4.81 million from $2.97 million, while cash and equivalents climbed to $37.85 million from $14.60 million at year-end 2025. Weighted-average common shares rose to 53.68 million from 6.37 million, which drove the per-share loss down to $0.09 from $0.47.

The players

Aprea Therapeutics

A clinical-stage biopharmaceutical company developing oral WEE1 inhibitors and yet to commercialize any product candidates.

EORTC-NCI-AACR Symposium

A major international oncology research conference co-hosted by the European Organisation for Research and Treatment of Cancer, the U.S. National Cancer Institute and the American Association for Cancer Research.

The details

Research and development expenses rose to $3.34 million from $1.64 million, mostly due to the Phase 1 study of APR-1051, an oral WEE1 inhibitor. The 2026 share count included 39.8 million shares issuable through warrants exercisable for nominal consideration, which increased the weighted-average base used to calculate per-share loss. The company projects its current operating plan will cover cash needs into the first quarter of 2028.

Dec. 31, 2025: Cash and equivalents comparison point of $14.60 million.
Sept. 30, 2026: Third quarter ended with the reported net loss.
Q2 2027: Expected completion of dose escalation and backfill expansion enrollment.
Nov. 20, 2026: Updated interim results presented at the EORTC-NCI-AACR Symposium in Barcelona.

Market Landscape

Clinical-stage biotech companies often finance through equity and warrants, which can sharply raise weighted-average share counts between reporting periods. This quarter's comparison shows per-share loss improving alongside a larger absolute loss, a dynamic analysts commonly examine when comparing early-stage peers.

Operators evaluating biotech partners or suppliers should compare cash runway and share dilution, not only the headline loss. Finance teams tracking vendor health may want to review how warrant issuance affects per-share metrics before drawing conclusions.

The takeaway

A rising share count can narrow reported per-share losses even when total losses grow, so review weighted-average shares and cash runway together. Companies projecting runway into 2028 should be monitored against the Q2 2027 enrollment milestone the company has identified.
