Thank you, Don. I really appreciate it and couldn’t be happier being part of the team. As we execute the plan that Don laid out and invest in increasing our PyroThin capacity to Plant 2, we think that it’s worth stepping back and spending some time, communicating in detail what makes this such a compelling mission. Thermal runaways and uncontrolled energy released in the cell triggered by various design, manufacturing and usage issues that ultimately result in the decomposition of all of the materials in the cell. A runaway cell’s high temperature can push the nearby cell into thermal runaway and such propagation usually destroys the battery or starts a fire. A lithium-ion battery pack when on fire consumes everything that it can due to its high temperature, including an entire car. These fires usually worsen with water as it reacts with lithium to expand the fire and only Class B type of extinguishers can be used to control them and put them out. The amount of energy released in thermal runaway is significant and equal to more than the energy used to charge the pack, given the formability of some of the materials within the pack. So, this is one of the most complex system-level issues that our customers face as they integrate and launch safe and reliable electric vehicles in record time. It’s really exciting to be enabling a safe and reliable transition experience through electrification as part of some great vehicle nameplates and body styles that we can all safely enjoy with our families. If we put ourselves in our customers’ shoes, integrating an EV is no easy exercise. This complexity increases when an OEM takes over the design and integration of the battery pack as well. In this feat of system integration, a vehicle has many diverging requirements or considerations that characterize it, where making one better tends to affect the other. These things determine whether your car is big, small, fast, efficient, agile, full of feel or boring to drive. Things like the vehicle size, weight, range, its performance targets, charging, discharging rates, ease of assembly, crashworthiness, recyclability, etcetera, drive battery pack design and architecture decisions. These decisions include what cell chemistry, what form factor, pack design, or layout are used, all with the intent of providing as much energy density per unit of mass and space in the vehicle. A key issue is that this energy density needs to stand the test of time and persist within an acceptable and consistent range that consumers see every day on their gauge as they fast charge or drive their vehicles in all sorts of temperatures and conditions for over 10 years. The integration is very complex even if safety is de-prioritized. However, we are seeing most OEMs go the extra mile prioritizing safety and addressing thermal runaway with both active measures in passive systems such as our PyroThin thermal barriers. Our value proposition is highest in NMC and mixed silicon graphite anode chemistry. The OEMs that most eagerly reach out to solve their challenges are focused on pouch or prismatic form factors, given their high-energy density and the space for passive protection features as these enable. The recent news of manufacturing defects, strong impacts, or erratic charge in new cycles causing EV fires are evidence that active systems alone can’t prevent thermal runaway 100% of the time. OEM investment in advanced active systems is expensive and time-consuming from an R&D standpoint as their validation requires testing multiple variants of every control strategy, times every type of cell, module and pack to the point of failure. Validating advanced controls for electrochemical processes is hard. We are encouraged by recent investments from OEMs and other Tier 1s in this space, given that we are all in the first inning of ensuring electric vehicle safety. But our customers foresee a passive system as a key part of their battery pack design in the same way that a vehicle with traction control, automatic emergency braking and collision avoidance systems still requires crumple zones, high-strength steel beams and doors, impact-resistant fuel systems, airbags and seatbelts. Again, this is a multi-variable problem with varying requirements, customer priorities and approaches. But as we started production and engage in conversations with more customers, the need for passive design elements and materials that work to provide thermal and fire safety as a system is becoming increasingly clear. There is no silver bullet to prevent or stop the effects of thermal runaway, and we intend to work with the rest of the industry to provide a very good lead bullet to this problem for a long time. We all know that not all materials are alike. And when these materials are fighting for precious space and weight inside of a battery pack to perform a critical safety function, they better deliver and prove their worth. At the core, our customers are looking for the thinnest and lightest material that provides the highest level of runaway prevention and protection. They also want a material that can compress and recover without degradation to keep the cells in their place as their form changes during their lifecycle. On the left, you can see in a simplified way how PyroThin and other materials work together as gas barriers, cell-to-cell barriers and compression pads inside of the pack. They tend to behave very differently on this thermal runaway – thermal resiliency or fireproofing range, along with the range of force under which they can be compressed and then be able to fully recover. You can also see that per unit of thickness, it would take twice the material and 2.8x the mass of the closest cell-to-cell barrier material to deliver the performance of PyroThin. These charts also show why increasing the thermal and fire resistance of the material per unit of thickness and weight, along with broadening its compressibility and recovery range are at the heart of our PyroThin R&D efforts. A thermal barrier that also acts as a compression pad is an example of how we will optimize content per vehicle or CPV. Beyond that, we will continue to focus R&D on the scalability of our manufacturing processes for the Aerogel base, along with automation tooling and systems for thermal barrier fabrication. On the far right, you can see how we’re currently thinking about CPV. Given that we’re in the first innings of this type of vehicle content, having just started supplying production parts in the last quarter, we’re showing you a broad range of where our supplied CPV lies, whether we’re a Tier 1 or Tier 2 supplier. Our understanding is informed by the vehicle programs that we’re supplying and it’s evolving with our quoting. What we know for sure is that we won’t win by solely focusing on increasing CPV, as we need to earn every cubic inch or ounce inside customers’ battery packs. We are focused instead on increasing the percentage of the overall thermal barrier content that is PyroThin. For our projection, we’re assuming a CPV that settles in the range of $300 to $325, with PyroThin content making up around 60% of that, understanding that this will vary with design changes, new program awards and customers’ increasing desire to prioritize safety. We really look forward to enabling customers accelerating EV product plans and evolving needs with a system-level approach to thermal runaway solutions. Serving as the partner with the right R&D, validation, design, integration and production capabilities gives us the right to play in multiple levels of the value chain, and we will continue delivering accretive CPV. Again, these are our initial thoughts and we will provide updates as our thinking evolves. With that, I’m happy to turn the call back to Don to summarize our strategy and deliver his closing remarks.
