TUCSON, Ariz., November 8, 2018 – HTG Molecular Diagnostics, Inc. (Nasdaq: HTGM) (HTG), a provider of instruments, reagents and services for molecular profiling applications, today reported financial results for the three and nine months ended September 30, 2018.

Recent Accomplishments & Highlights:

• Achieved revenue of $4.7 million and $13.8 million for the three and nine months ended September 30, 2018, respectively, which represents a 26% and 101% increase over the same periods in 2017, respectively.

• Announced three amendments to the second PDP Program (SOW Two) under the Master Assay Development, Commercialization and Manufacturing Agreement (the Governing Agreement) with QIAGEN Manchester Limited (QML). Development activities for the clinical trial assay have been completed, and the amendments relate to the next phase development activities, including the use of the investigational use only (IUO) assay developed in the initial-phase in a retrospective clinical trial and in additional disease indications.

• Entered into an amendment to the third PDP Program (SOW Three) under the Governing Agreement with QML. Initial assay development activities under SOW Three are complete, and the amendment provides for the development of an IUO assay, subsequent retrospective testing of clinical trial samples, design verification and, subject to satisfactory achievement of relevant performance and regulatory milestones, regulatory submission in the US and EU necessary for the commercialization of a companion diagnostic assay for a corresponding pharmaceutical company drug.

• Launched the HTG EdgeSeq Precision Immuno-Oncology Panel and began delivery of orders to translational and clinical researchers working in the field of cancer immunology and/or cancer immunotherapy. This research use only profiling panel provides a large, comprehensive set of genes involved in the host immune response to tumors.

• Announced the pre-launch introduction of the new HTG EdgeSeq Mouse miRNA Whole Transcriptome Assay (WTA) with product availability for shipment expected in the fourth quarter of 2018. The HTG EdgeSeq Mouse miRNA WTA is designed for use with disease mouse models, including oncology, to identify and quantify the expression of a wide range of miRNAs in a variety of sample types, including formalin‑fixed paraffin-embedded tissue.

• Appointed Dr. Maureen T. Cronin as HTG’s new Chief Scientific Officer and Senior Vice President in November 2018. Dr. Cronin brings extensive experience in genomic technology, laboratory test and pharmaceutical company therapeutics development, as well as regulatory compliance and academic clinical research to HTG.
