MEDBOTX™ represents the evolution into a broader point-of-care manufacturing platform designed for personalized medicines, peptides and advanced dose formats

Potential U.S. peptide reclassification and possible inclusion of select peptides on the Section 503A Bulks List could create a timely opportunity for MEDBOTX™ in compounding pharmacies, hospitals and personalized medicine settings

Toronto, Ontario--(Newsfile Corp. - May 27, 2026) - PharmaTher Holdings Ltd. (CSE: PHRM) (OTCQB: PHRRF) ("PharmaTher" or the "Company"), a pharmatech company focused on enabling personalized medicine through robotic 3D printing, today announced that it is strategically evolving its platform focus from PatchPrint™ 3D printer to MEDBOTX™, the Company's robotic 3D printing platform designed for personalized medicines, peptides and advanced pharmaceutical dose formats.

PharmaTher believes MEDBOTX™ represents the next stage of the Company's growth and the evolution of its work in pharmaceutical R&D, microneedle patches, and 3D printing. By expanding beyond a single-dose format such as microneedle patches, MEDBOTX™ gives PharmaTher a broader and more scalable platform for personalized, patient-specific and small-batch pharmaceutical manufacturing. The Company expects MEDBOTX™ to become the central technology platform for its product development and sales, partnerships, and strategy in personalized medicines.

"MEDBOTX™ represents the next stage of PharmaTher's work in pharmaceutical drug development and manufacturing," said Fabio Chianelli, Chief Executive Officer of PharmaTher. "We believe our MEDBOTX™ platform provides a focused path to participate in the growing demand for personalized medicines, particularly peptides, where flexible, small-batch and point-of-care manufacturing may become increasingly important as the U.S. evaluates potential regulatory pathways for certain peptide compounds and specialty pharmaceuticals."

MEDBOTX™ is designed as a point-of-care and small-batch manufacturing platform that may support personalized dose forms, including polypills, tablets, oral films, gels, suppositories, chews, patches, osmotic-pump formats, and other advanced drug delivery formats. PharmaTher's initial commercial focus is expected to include personalized medicines, regulated peptide opportunities, compounded pharmaceuticals, and partner-facing formulation and development services.

MEDBOTX™ for Personalized Medicines

PharmaTher believes healthcare is moving toward greater personalization, including patient-specific dosing, alternative delivery formats, combination therapies, improved adherence and localized manufacturing. These trends are particularly relevant in settings where conventional mass manufacturing may not address the needs of specific patients, prescribers or clinical workflows.

MEDBOTX™ is designed to support this shift by enabling programmable, flexible and potentially scalable production of personalized medicines and advanced dose formats, which could be relevant for:

1. Hospitals and compounding pharmacies, including 503A pharmacies, seeking point-of-care capabilities to support individualized, prescription-based medicines;
2. PharmaTher's internal product pipeline, including custom peptides, psychedelics, and microneedle patch development programs; and
3. Specialty pharmaceutical and biotech partners seeking formulation development and small-batch production for clinical studies and commercialization.

Peptides: A Timely Opportunity for MEDBOTX™

PharmaTher believes peptides represent an attractive near-term opportunity for MEDBOTX™. Peptides are an important and growing class of therapeutic compounds, but many can present formulation, stability, delivery and manufacturing challenges. These challenges may create a need for flexible manufacturing platforms capable of supporting customized dose forms, small-batch production and patient-specific formulations.

The U.S. regulatory activity involving therapeutic peptides could become an important external catalyst for MEDBOTX™. The U.S. Food and Drug Administration's Pharmacy Compounding Advisory Committee is scheduled to meet on July 23-24, 2026, to discuss certain bulk drug substances being considered for possible inclusion on the Section 503A Bulks List, including BPC-157-related, KPV-related, TB-500-related and MOTs-C-related bulk drug substances.

If certain peptides gain a broader lawful pathway for compounding under appropriate medical supervision, PharmaTher believes MEDBOTX™ could become increasingly relevant as a platform for personalized peptide formulation development, small-batch production, and point-of-care manufacturing workflows in compound pharmacies and hospitals.

MEDBOTX™ Commercial Strategy

PharmaTher intends to focus its MEDBOTX™ commercialization strategy on platform opportunities that may include:

• System placements with compounding pharmacies, hospitals, clinics, research institutions and qualified partners;
• Consumables and formulation inputs that may support recurring revenue opportunities;
• Internal product development, including peptide and psychedelic formulations and microneedle patch programs;
• CDMO-style services for partners seeking formulation development and small-batch development; and
• Strategic collaborations involving bioprinting and bio-integrated applications, including hydrogel-based implants, tissue scaffolds, and smart wearables.

The Company expects its near-term MEDBOTX™ priorities to include advancing toward commercial launch, identifying commercial partnerships for regulated peptides and compounded pharmaceuticals, and positioning MEDBOTX™ as PharmaTher's primary platform for personalized medicine manufacturing.

MEDBOTX™ Commercialization Milestones

The Company's expected MEDBOTX™ commercialization milestones include:

Summer 2026: Completion of the MEDBOTX™ system for internal R&D and commercial demonstrations.

Fall 2026: Commencement of commercialization activities, including engagement with potential commercial partners, compounding pharmacy partners, hospitals, clinics, research institutions and pharmaceutical development collaborators.

Ongoing: Development of proprietary "printing recipes" for selected peptides and compounds, supported by GMP-aligned workflow software, AI-assisted formulation development, related process know-how, and new intellectual property filings to strengthen the Company's personalized medicine and advanced manufacturing platform.

PharmaTher is currently collaborating with a bioprinting manufacturer to finalize customizations and scale up manufacturing of MEDBOTX™.

PharmaTher's focus is clear: advance the MEDBOTX™ platform, engage commercial partners, develop proprietary formulation and manufacturing know-how, and build long-term value in the growing market for personalized medicines.
