In conjunction with this shutdown, ActoBio's portfolio of intellectual property is available for prospective transactions. Precigen Exemplar Exemplar is committed to enabling the study of life-threatening human diseases through the development of MiniSwine Yucatan miniature pig research models and services. Historically, researchers have lacked animal models that faithfully represent human diseases. As a result, a sizeable barrier has blocked progress in the discovery of human disease mechanisms; novel diagnostics, procedures, devices, prevention strategies and therapeutics; and the ability to predict in humans the efficacy of those next-generation procedures, devices, and therapeutics. Exemplar's MiniSwine models are genetically engineered to exhibit a wide variety of human disease states, which provides a more accurate platform to test the efficacy of new medications and devices.
As of December 31, 2024, Exemplar had 25 employees. Exemplar's primary domestic production facilities are located in Sioux County and Johnson County, Iowa, and include approximately 57,960 square feet of production, lab, and office facilities. Competition: Healthcare Business While we believe that our novel approach to developing the next generation of gene and cell therapies utilizing our AdenoVerse and UltraCAR-T platforms to target the most urgent and intractable challenges in immuno-oncology, autoimmune disorders, and infectious diseases provides us with competitive advantages, our industry is highly competitive and subject to rapid and significant technological change.

We have completed a Phase 1 clinical trial of PRGN-2009 as a monotherapy or in combination with bintrafusp alfa, or M7824, an investigational bifunctional fusion protein, for patients with HPV-associated cancers in collaboration with the National Cancer Institute, or NCI, pursuant to a cooperative research and development arrangement, or CRADA. PRGN-2009 is being evaluated in two Phase 2 clinical trials in combination with anti-PD1 monoclonal antibody, pembrolizumab, for patients with HPV-associated cancers in collaboration with NCI pursuant to a CRADA.
The first Phase 2 clinical trial is designed to evaluate PRGN-2009 in combination with anti-PD1 antibody, pembrolizumab, in adult patients with newly-diagnosed HPV-associated oropharyngeal cancer is ongoing in collaboration with NCI pursuant to a CRADA. The primary objective of the study is to determine if there is an increase in CD3+ tumor infiltrating T cells post treatment compared with pre-treatment. Secondary objectives include safety and overall survival (OS). The second Phase 2 clinical trial is randomized, open-label clinical trial of PRGN-2009 in combination with pembrolizumab to treat patients with recurrent or metastatic, or R/M, cervical cancer. Patients in the Phase 2 trial will be randomized 1:1 to the combination of PRGN-2009 and pembrolizumab (cohort 1) or pembrolizumab monotherapy (cohort 2).

Behind the comparison

Sources and methodology

Price return uses split-adjusted daily closes and excludes dividends. Both stocks start on the first shared trading day within the selected window. Unavailable metrics leave gaps.

Financials use SEC canonical statements available by the displayed cutoff, retaining each company's fiscal period end. Annual and quarterly amounts are shown separately. P/E is unavailable when earnings do not support a positive ratio.

Business overlap uses industry tags from annual filings released in 2025. Each core activity receives full weight; each material activity receives one quarter of that weight. Rarer industries carry more weight. We sum the smaller exposure for each shared activity and divide it by the sum of the larger exposure for every activity in either company. This measures business overlap, rather than price correlation or expected returns.

Search eligibility requires distinct issuers, a shared core category and at least 20% weighted overlap, supported by industry or sector evidence and specific business activities. Broad classifications require stronger overlap within the same sector. Comparisons also need at least 252 shared price observations within two years, recent trading and a common sourced revenue or net-income trend. Missing P/E or gross margin alone does not exclude a comparison. The eligibility snapshot refreshes daily. Related comparisons use a separate, stricter peer rule; their ten-peer discovery limit does not limit search eligibility. Other stock pairs remain available in the comparison tool.

Statements available through 2026-10-23. Industry snapshot: 2025-12-31 · 5,721 classified issuers.
