Thanks, Allison and good afternoon, everyone. Our second quarter saw healthy sales growth, operating profit and cash flows. This was on top of 27% net sales growth in the same period last year. We secured additional distribution at Walgreens, launched end cap [ph] displays at Rite Aid, started testing skin care at Ulta Beauty and began retail expansion in Germany. Offsetting this progress, we've seen a notable deceleration on our track channel sales. I'll review what we're doing to reverse these trends. Before doing so, I'd like to provide context on where we currently stand. e.l.f. is a 15-year old grand compared to legacy players that are over 100 years old. We are still young in our brand building journey and believe we have tremendous whitespace ahead of us. As I reflect on the past four years, we've done a number of things well to build competitive advantage. We have a brand that beauty enthusiasts love with the highest value and retention ratings in our category. We have an innovation capability that can launch 100 new items a year in as few as 13 weeks in both color and skin care. We've built a strong distribution base and remain the most productive color cosmetics brand at Target and Wal-Mart on a sales per linear foot basis. Our compelling proposition for retailers continues to get rewarded with new distribution and space. We've honed an operational advantage that provides the best combination of cost, quality and speed in our industry and we've built a great team and infrastructure to further scale the business. With that backdrop, let me now review the three things we're doing to address recent softness in track channels. First, it's time to spend more behind the brand. Second, putting more focus on our key items. And third, taking measures to get optimal assortment at retail. Let me take you through each of these. First, it's time to spend more behind the brand. Over the last four years, we've grown our community to 37 million followers and have increased unaided awareness from less than 3% to 17% using our authentic and efficient program such as Beautyscape. As greater the ROI of these activities has been, the marketplace continues to get increasingly crowded and noisy. In the last 18 months, we've seen the growth of multiple mega influencer driven brands that are competing for our younger consumers' attention. We believe our brand proposition is highly compelling with high quality, extraordinary value and 100% cruelty free, yet, we've not invested enough to communicate our message. We believe now is a natural time to increase investment behind the brand. If you think of our evolution, we spent the first four years building our distribution. We now have a strong footprint that we believe will benefit from increased brand support. We will test broader awareness and engagement efforts in the back half of this year that we can expand in 2019. We intend to fund this investment in part through operating leverage in the business. For example, we're making capital investments in our distribution facilities that we expect to drive labor savings. One of these projects is opening a second distribution center in Ohio to serve our e-commerce business. We expect this facility to reduce our operating costs, enable two day standard delivery to 90% of the country. Another project involves bringing similar automation in our West Coast warehouse. We expect these projects to be completed in 2019. Second is putting greater focus on key items. We have real strength in innovation output and speed. We launch over 100 items per year in as fast as 13 weeks. While we are proud of this innovation capability, we have an opportunity to bring greater focus to some of our best items. We have primarily marketed products when we first put them in our direct channels, but have not done nearly as good a job when we expand distribution to our national retailers. Our plan is to bring greater focus to some of our best products and support them with more holistic storytelling. As an example, in June, we put focus behind having America's number one primers. In August, we'll put an integrated effort behind beauty shield magnetic mask. Our $24 magnetic mask is the great example of our high quality extraordinary value proposition as the only other thing like it in the market is a $75 prestige product. You'll also see us further amplify our leadership position with America's number one brushes. Third is taking steps to get optimal assortment at retail. Each year, we launch new items in our direct channels. We take sales and consumer review data and make assortment recommendations to our national retail partners for their annual shelf resets. We have a strong track record over the past 10 years of driving productivity through this model. This year, we did not have the appropriate mix between new and existing products. Our new products are performing to our expectations, while we saw a greater drop off in our carry forward items. Given how much our consumers value innovation, it is important to get more of our new items on shelf. A key enabler to improve our assortment is Project Unicorn. This is a major product, package and shelf initiative that elevates brand presentation and improves navigation. By eliminating and changing outer packaging on select SKUs, this initiative will enable us to fit more new products within existing space. Project Unicorn will also allow us to highlight our premium componentry and colors, showcase our leadership position in categories like by brushes and primers and tell better product stories. Many of our national retail partners are enthusiastic about the improved space efficiency and presentation Project Unicorn will bring when it hits shelves in the spring of 2019. In summary, we're highly focused on addressing current business trends within track channels. These changes will take some time to fully implement, so we believe it's prudent to revise our 2018 outlook. John will discuss this in more detail later in the call. Importantly, the current challenges have not dampened our enthusiasm for the long term potential of the e.l.f. brand. Speaking both personally and as the second largest shareholder in the company, I have tremendous confidence in our ability to leverage the platform that we've assembled to drive value. To that end and as announced today, my plan is to purchase an additional $0.5 million of e.l.f. shares. My ownership stake is over 12% of the company and I have purchased 92% of my shares. Our entire team is highly aligned to delivering long-term shareholder value. My confidence is further bolstered by the wins we continue to get in a competitive marketplace. Even with recent trends, we remain the most productive brand on a sales per linear foot basis at our two largest customers, Wal-Mart and Target. Our Ulta Beauty expansion has exceeded our expectation and we recently started testing skin care in a subset of their stores. We offer compelling retailer proposition and continue to gain distribution and shelf space. As previously announced, we are expanding into additional Walgreens stores. We're also pleased to announce that we'll be broadening distribution to Rite Aid. An issue with an end cap display program this year and in line distribution to follow in 2019. The brand continues to resonate internationally with expansion into additional super drug stores slated later this year and the launch into Feelunique, the largest beauty e-tailer in the UK. We are beginning our initial distribution in Germany with the subset of Mueller stores. [indiscernible], a major European retailer launched e.l.f. online in Germany and will test in a subset of their retail doors, an approach similar to that of Ulta Beauty in the US. While many of these developments do not significantly impact 2018 revenue, they show the power of our brand and continue to gain space and distribution. I will now turn it over to John to discuss our financial results and 2018 outlook.
