Good afternoon everyone. Welcome to Intrexon's first quarter 2018 investor conference call. I'm Tom Shrader, Vice President of Communications and Strategy at Intrexon. And I'm joined by Joel Liffmann, Senior Vice President of Finance; and Thomas Bostick, Intrexon's COO. R.J. Kirk, our CEO, will join us for the Q&A session. Forward-looking statements. During this conference call, we will make various forward-looking statements. Investors are cautioned that our forward-looking statements are based on current expectations and are subject to risks and uncertainties. A number of factors could cause actual results or outcomes to differ materially from those indicated. Please read our Safe Harbor statement contained in the earnings press release as well as Intrexon's most recent SEC filings for a more complete description. This afternoon's press release and our discussions may reference certain non-GAAP financial measures, including adjusted EBITDA and adjusted EBITDA per share. We use these financial measures as a more accurate estimate of our ongoing financial position. Reconciliations to GAAP measures are contained in the earnings press release as well as on the Investors section of our website. The format of today's call will include a review of Intrexon's progress last quarter and some more recent updates by myself and Tom Bostick and then a recap of our financial situation by Joel Liffmann. The call will end with a Q&A session. Again, our CEO, R.J. Kirk, will join us for the Q&A part of the call. Okay, next slide. So, just an intro to Intrexon's healthcare division. As a reminder, the most advanced human therapeutic efforts at Intrexon are now grouped into two wholly-owned subsidiaries; ActoBio Therapeutics for L lactis-based delivery of fully folded biological therapeutics; and Precigen for cell and gene-based therapies. These reorganizations were made as part of Intrexon's move to more fully develop our own discoveries and move away from the early-stage partnering strategy we call the ECC model. These moves don't preclude partnering and several of our historical collaborations continue, but future partnerships will likely occur later. This change will reduce our ECC revenues in the short-term, but were designed to drive long-term shareholder value. Okay, next slide. Okay, this time we're going to start with ActoBio Therapeutics, our subsidiary run by Pieter Rottiers. We believe ActoBio represents a novel delivery approach but a relatively de-risked approach overall because many of the therapeutics delivered by L lactis are active and systemic therapeutics. On the slide, you can see a detailed time line of ActoBio's expected clinical activities. Today we are talking about a new trial, but Acto has an ongoing Phase II trial with AGO13 in oral mucositis. And the time line for the trial is indicated on that slide as well. Okay, today's -- the actual news in the program, AG019, a product candidate enabled by ActoBio technology is being developed in a joint venture between Acto and T1D Partners, and its IND has been cleared by the FDA to initiate a Phase I/II trial study for the treatment of early onset Type 1 diabetes. We expect to begin dosing this summer as also indicated on the slide. Okay, AGO19 is an L lactis strain that simultaneously delivers the Type 1 diabetes antigen pre-insulin along with the inflammatory cytokine, IL-12. The Phase I portion of the trial will deliver AGO19 alone to demonstrate safety, and then the Phase II portion of the trial will add low-dose anti-CD3 to further calm the immune system and second, to stimulate T cell homing to the gut. Next slide, some details about the trial. This trial represents the first experience in humans for AGO19, but it's based on very well-behaved preclinical data. So, what do we mean by well behaved? On the figure, you can see detailed preclinical experiments with diabetic mice. As you see from the figure, each of the three components from the trial when tested induced some fraction of mice to deliver to -- revert to a non-diabetic state. Perhaps more interesting, all of the double therapies were better than the single therapy and the triple therapy that we will test on our trial was the best of all. So, that's remarkably consistent data. Also indicated in our press release, in animals with early-stage disease as defined by glucose levels, the triple therapy reverted nearly 90% of animals to a normal glycemic state. Obviously, repetition of anything like this in humans would be transformational. Okay, next slide, turning now to Precigen. As a reminder, much of Precigen's pipeline remains under wraps, but we have said that many of the programs will involve our technologies that allow regulated expression of large genetic payloads. So, on the slide, we're happy to announce today that our gene therapy trial in heart failure is open and enrolling. So as of today, the trial is a little bit similar to AGO19 in the sense that Precigen has used sophisticated delivery technologies to take a multi-genic approach in an area where single-gene approaches have shown promise. For a review of the details of this program, Precigen has engineered the delivery of genes from each of the three major classes of proteins implicated in the repair of cardiac tissue: stem cell factors to generate new cardiomyocytes; proteins for efficient calcium handling, so damaged cardiomyocytes can relax more fully and function more efficiently; and finally, an angiogenic factor that help resupply oxygen to the damaged tissue. So, that's the trial, again, its three components, all of which have been validated. So, now to turn to a final update of human therapeutics. The next slide is our updated scorecard. So, as I just said, AGO19, the IND has cleared, and we expect dosing this summer. Second, the Xogenex gene therapy trial for heart failure has started and is actively enrolling patients. And then finally, just a quick update on the point-of-care CD19 trial. We filed the IND as scheduled and we're waiting to hear. So, that's an update for healthcare. Next, we'll turn to energy. Okay, next slide. So, now we'll turn to an energy update. First off, we can say that our partnership process is on track, and we continue to plan to break ground on a commercial 2,3 BDO plant by the end of the year. Next slide, our methane bio conversion platform, or MBP. MBP is our program to turn natural gas, the lowest cost and most available source of carbon, into more valuable and usable carbon forms. Carbon upgrading has been going on for nearly 100 years, but we believe our approach will be both more efficient and less CapEx-intensive than anything currently available. As a reminder, our carbon upgrading is carried out by an unusual bacterial species called the methanotroph that usually uses natural gas and that we have engineered to make fuels an industrial building blocks. Okay, methane upgrading. This slide indicates that the key to our approach is the ability to start from low-cost natural gas rather than higher cost sugars. The curve on the slide documents the price gap between gas and oil. It's not always constant, but it's generally pretty significant. To give a calibration point, in terms of carbon cost, a $3 natural gas equates to oil at about $18 per barrel, while the per-carbon cost of sugars is higher than fuels. Today, natural gas is trading lower than $3, and oil is trading between $70 and $80 per barrel. Just to summarize, it's already possible to convert other carbon sources to fuel, other companies have done this. What's important is to start from a carbon source that makes commercial sense. For the reasons above, we believe natural gas makes good sense as a starting material. Next slide, our initial products. On the slide is an overview of the six products we have proven we can make and the three we have -- on which we focus; isobutanol, 2,3 BDO and 1,4-BDO. As you can see, all are significant markets. 2,3-BDO is now considered our lead product because progress in the program was rapid, and we reached profitable yields of 2,3-BDO before isobutanol, despite starting much later. Some of the attractive features of 2,3-BDO are indicated on the slide and included. The market is growing. The demand for 2,3-BDO is growing faster than GDP. In addition, there is something like 20 suppliers, so there's no monopoly. It's easy to get into the market if you can make the product. I -- the field has attractive contracts. They're generally long-term. And then, as I'll reiterate in a minute, catalytic conversion to 1,3-butadiene has already been established. So 2,3-BDO is our lead product, and it's an attractive product. If you can make the product to spec, you can sell it. Okay, next slide, our scorecard for the energy sector. The important thing this quarter is that we made progress with 2,3-BDO with isobutanol and with 1,4-BDO. And as we've indicated before, one of the key features of the energy program is that we're getting better at the overall process of pathway engineering. Our target projects all have common steps in their synthesis, and many of the products have overlapping pathways of synthesis. So, advances in one product can help with others. The growth curve concept is indicated on the slide where our first target, isobutanol, moved slowly while some others, including 2,3-BDO, saw rapid yield increases when we started later. The important point is that the genetic toolbox we built is paying dividends across the Board. As I've previously mentioned, these products share a common pathway. So, many of the learnings from -- that we now have from 2,3-BDO at high yields will translate to isobutanol and the 1,4-BDO program. So, a review of the quarter. For the quarter, we had several advances. The major advance this quarter was about a 25% increase in the yields of 2,3-BDO, our lead product. We previously announced that we would break ground for a 40,000-ton facility this year and this advance in yield keeps us on that track. A second important advance with 2,3-BDO was successful catalytic conversion of our pilot plant product to 1,3-butadiene. 1,3-butadiene is the immediate starting point for synthetic rubber and demonstrating conversion of 2,3-BDO to 1,3-butadiene was important. In fact, our conversion partner commented that our 2,3-BDO was unusually pure. This feature is attractive to buyers, and we are in discussions regarding the possibility of long-term take-or-pay contracts. Okay. And finally turning to isobutanol. We also had a significant advance in the reengineering of the problem enzyme in isobutanol synthesis. We've said previously that the bottleneck in isobutanol production resulted from a single enzyme that we call promiscuous. This quarter, Intrexon scientists successfully reengineered this enzymatic activity, resulting in a 40% improvement in yield. As a result after a somewhat lengthy delay, we hope to begin, start talking about isobutanol synthesis again. So on that lofty note, I'll turn things over to Tom Bostick for an update on the rest of our businesses.
