Thank you, Jim, and good afternoon, everyone. We are very excited about our acquisition of Spindle Biotech, and we feel that integration with our LinearDNA IVT template to create our new Linea IVT platform overly compelling and differentiated offering to mRNA stakeholders and addresses two key pain points in mRNA manufacturing. One, we use the plasmid DNA as starting material and two, double stranded or DS RNA contamination. When utilizing the customer's mRNA production workflow, we believe our Linea IVT platform will produce a higher purity mRNA product with a simplified workflow compared to conventional mRNA production. The mRNA market continues to grow at breakneck pace with approximately 350 therapies in preclinical or clinical development. These therapies target a wide range of indications, ranging from infectious disease to oncology and genetic disorders with an increasing number of therapies reaching late clinical trials. mRNA vaccine for common infectious diseases such as RSV, are on the horizon and represent very large mRNA manufacturing opportunities. It's with these opportunities in mind that we have launched the Linea IVT platform. Our Linea IVT platform is built upon the integration of our LinearDNA IVT template and the proprietary fusion RNA polymerase or RNAP that we acquired from Spindle. The novel RNAP developed by Spindle is a fusion protein consisting of wild-type T7 RNAP and DNA-binding domain. The DNA-binding domain has a high affinity for certain chemical compounds that can be efficiently added to our LinearDNA IVT template via PCR. Our PCR-based platform's unique ability to add these chemical modifications efficiently and cost effectively is the enabling technology for Spindle Biotech something allowing us to extract the full benefit of this Spindle RNAP. At the time of the acquisition, Spindle was pre-commercial but has attracted an amicable list of partners drawn from the upper tier biotech. So it held back the inability to manufacture chemically modified IVT template at scale. Our PCR-based LinearDNA platform solve this issue and unlocks the full value of the Spindle RNAP. As you noted, acquiring Spindle and launching the Linea IVT platform expands our mRNA related total addressable market. On a stand-alone basis, our Linear IVT -- or excuse me, our LinearDNA IVT templates are relative to approximately 5% of the mRNA manufacturing balance sheet. And only a limited amount of DNA template is required to produce very large amounts of mRNA with the ability to now sell a paired IVT template with the Spindle RNAP under the Linea IVT platform, we expect to have relevance to over 20% of the mRNA manufacturing value chain, representing an approximate 4x increase in the company's mRNA related total addressable market. As I noted, our newly launched Linea IVT platform address two key pain points interventional mRNA manufacturing. Avoiding the use of plasmid DNA IVT template and minimizing DS RNA contamination all while also providing simplified workflow. On the top of Slide 9, which is the current slide, represents a conventional mRNA production workflow that utilizes plasmid DNA and conventional wild-type T7 RNAP. The bottom of that slide represents a potential Linea IVT mRNA production workflow using both chemically modified Linea's DNA IVT template and the Spindle RNAP. I will highlight two important differences between processes. The first difference is the simplification of the front end of the mRNA manufacturing prop. The use of DDNA or plasmid DNA as a template causes long lead times to require numerous steps and costs specific to its use, including expensive enzymes and increased regulatory scrutiny and additional filtration steps. By replacing plasmid DNA with LinearDNA in the bottom workflow, these upstream plasmid-related pain points are reduced, resulting in a simpler mRNA workflow. We estimate that using LinearDNA to move to about 40% of the extreme steps involved in conventional plasmid-based IVT, which is the top workflow. Second difference is in the streamlining of the back end of the mRNA manufacturing process by reducing DS RNA contamination through unique combination of chemically-modified linear template and the Spindle RNAP. DS RNA contamination is a byproduct of wild-type T7 RNAP used in all mRNA manufacturing. T7 is used throughout the mRNA industry due to its ability to create large amounts of RNA from a small amount of DNA template. But there are trade-offs, including the production of problematic DS RNA. DS RNA is a stimulatory and inflammatory byproduct that needs to be removed from mRNA, which is a single trend construct before it can be used as the therapeutic. Currently, DS RNA is removed via expensive and complex downstream purification method. Now due to the ability of our Linea IVT platform to significantly reduce DS RNA contamination without sacrificing mRNA yields, we believe the need for downstream purification will be reduced and further streamlining the mRNA workflow for our customers. So in summary, by simplifying both the upstream and downstream aspect of mRNA production, we believe our Linea IVT platform can enable our customer to produce better RNA with reduced workflow -- with reduced peripheral steps and time lines. Now shortly after we acquired Spindle, we attended a key industry conference call. The reception to our new platform is very encouraged. The plasmid DNA and DS RNA contamination pain points addressed by our IVT platform are called across the industry. And it's clear that manufacturers and developers are seeking new and differentiated approaches to mRNA production. Equally encouraging the mRNA initiatives are gaining strong traction within the industry. We are today is due to the highest number of valuation customers since the launch of our IVT template one year ago. These customers range from preclinical mRNA therapy developers to CDMOs to large therapy developers pursuing mRNA vaccines for common respiratory illnesses. Our future planned cGMP quality production capabilities are critical to converting these customers from the evaluation stage to large sale supply agreements, and we remain committed to launching this capability in early calendar year '24. Looking ahead, our business development efforts are focused on further elevating our profile in the marketplace and building a broader base of interest in our Linea IVT platform. Our efforts will also center on continued optimization of the platform for both conventional mRNA products as well as a growing number of self-amplifying or SA mRNA therapies. At the same time, we are hard at work at updating our sales and marketing material to highlight the Linea IT platform to new and existing customers. Finally, we remain committed to building our patent state around our Linea's Rx products and services. The acquisition of Spindle brought with it a large portfolio of pending international patent applications covering the enzyme as well as various other modalities of next-generation RNA production. In addition, the company continues to pursue patents protection around both the LinearDNA and Linea IVT platforms. Now let me turn the call back to Jim for further remarks.
