Vector is an early-stage company moving quickly into its revenue and sustainability phase. Under the guidance of a strong commercial team, the Company is advancing five verticals targeted at driving revenue and profitability: cGMP peptide manufacturing; VectorMist™ for perioperative pain management in laparoscopic surgery; Valor™ transdermal delivery of peptides; biomechanical molecular instruction technology for drug delivery; and localized delivery of oncology therapies for pancreatic cancer. Vector is currently focused on commercializing the first two verticals — peptide manufacturing and VectorMist — for launch in calendar year 2026, and is encouraged by the pace of progress across both.

Peptide Manufacturing: Scaling Toward First Revenue

Vector's peptide manufacturing operation is scaling up this quarter, with first production batches expected in August 2026 and initial revenue anticipated before the Company's fiscal quarter end in August. Vector's commercial focus is the sports medicine segment, where quality and trust are paramount, and the Company has signed agreements with leading athletes to serve as product spokespeople as part of its pre-launch marketing program.

Vector is one of only a small number of U.S. companies manufacturing pharma-grade peptides under FDA license and cGMP standards, with validated testing for sterility, endotoxin, potency, and purity performed on every batch. According to Grand View Research (2025), the global peptide market is approximately US$141 billion and is projected to reach US$295 billion by 2033. Demand is currently outstripping licensed supply: as of this release, Semaglutide (GLP-1) is on an industry-wide three-week backorder, underscoring the market's need for supply chains that are properly licensed, manufactured under cGMP, and independently tested. Production capacity is expected to reach approximately 800,000 vials per month beginning in early fall 2026, and the Company is targeting premium pricing with expected gross margins in the range of 60% to 80%. Samsung's recently announced purchase of CDMO PolyPeptide Group AG for US$1.8 billion to gain manufacturing capacity is, in the Company's view, a positive indication that Vector is strategically well positioned to take advantage of the rapidly growing demand for peptides.

The Company also recently announced the buildout of a highly technical distributor sales team with deep experience in the orthopedic and sports medicine channels to drive adoption at launch.

VectorMist: On Track for FDA 510(k) Submission

VectorMist, Vector's perioperative pain management technology for laparoscopic surgery, remains on track for submission to the FDA for 510(k) clearance, a process that typically involves a 90-day review from submission. Pending a favorable FDA review, the Company believes VectorMist could begin generating revenue before the end of calendar year 2026. Vector has initiated early distribution discussions with a number of companies in the laparoscopic field, and expects those discussions to intensify following the FDA filing.

Across every vertical, the Company's goal remains the same: to bring the science of precision to therapeutics — Smart, Steered, and Sustained.
