Ladies and gentlemen, thank you for standing by. My name is Brent, and I will be your conference operator today. At this time, I would like to welcome everyone to the Datto third quarter 2021 earnings conference call. All lines have been placed on mute to prevent any background noise. After the speaker's remarks, there will be a question and answer session. If you would like to ask a question at that time, simply press Star, followed by the number one on your telephone keypad. If you'd like to withdraw your question, again, press Star one. It is now my pleasure to turn today's call over to Mr. Ryan Burkart, Director of Investor Relations. Please go ahead. Thank you, operator. Good afternoon, everyone, and thank you for joining us today to review Datto's third quarter 2021 financial results. With me on the call today are Tim Weller, Chief Executive Officer, and John Abbot, Chief Financial Officer. During this call, we may make statements related to our business that would be considered forward-looking statements under federal securities laws, including projections of future operating results for our fourth quarter and full year ending December 31, 2021. As a result of a number of factors, actual results may differ materially from those projected in such statements. These factors are set forth in the earnings release that we issued today under the section captioned "Forward-Looking Statements," and these and other important risk factors are described more fully in our reports filed with the Securities and Exchange Commission. We encourage all investors to read our SEC filings. The following statements reflect our views only as of today and should not be relied upon as representing our views as of any subsequent date. In addition, Datto undertakes no obligation to publicly update or revise any forward-looking statements made here. Additionally, non-GAAP financial measures will be discussed on this conference call. A reconciliation of these non-GAAP financial measures to the most directly comparable GAAP financial measures is available in our third quarter 2021 earnings press release, which can be found on our investor relations website. A financial supplement and webcast of today's call are also available on our investor relations website. I would also like to inform you that we will be participating in two investor conferences in the coming weeks, including the RBC Capital Markets Global Technology Conference and the Barclays TMT Conference. Please reach out to me if you're interested in joining our schedule. With that, I'll turn the call over to our Chief Executive Officer, Tim Weller. Tim? Thank you, Ryan, and many thanks to everyone for joining us on the call this afternoon. We are excited to report strong Q3 results and to raise guidance again for 2021. I'll begin with a few highlights from the quarter, followed by an update on two significant product launches that we made in security and cloud, which solidify our leading position in providing cybersecurity solutions for our MSP partners. Finally, I'll turn the call over to John Abbot to discuss our financial results and guidance in more detail. The third quarter was another record quarter for Datto. Subscription revenue growth was 20% year-over-year, reflecting another quarter of sequential acceleration. Our growth continues to be paced in percentage terms by Datto SaaS Protection and Datto RMM, both of which also have strong new security add-ons. Our business continuity and disaster recovery product, BCDR for short, continues to re-accelerate with another sequential increase in new ARR. Overall, all major products and geographies saw healthy growth. We ended the quarter with $627 million of ARR, up almost $29 million from Q2, and we added 400 net new MSPs in the quarter, bringing the total number of MSP partners we serve to 18,200. ARR per MSP also continued to increase, demonstrating the ongoing strength of our MSP cohorts. Overall, I'm delighted with the way our partner-facing teams executed in delivering another great quarter. On the product side in Q3, we launched two new significant offerings, SaaS Defense as a security add-on for our SaaS Protection Continuity product, and Datto Continuity for Microsoft Azure, extending our flagship BCDR product into the public cloud, where Azure is far and away the most popular with MSPs. I'll give some additional details on each now. Let me start with SaaS Defense, our newest security product. This product addresses the number one cybersecurity attack vector, which is email and related attachments. In fact, MSPs report that 64% of ransomware attacks on their clients originate in Microsoft 365 inboxes. Our SaaS Defense solution has its foundations in our acquisition earlier this year of BitDam, an Israel-based company. We have run independent third-party testing of our proprietary technology against five of the most widely used email security solutions available today, and we come out in the top one or two on effectiveness and had the lowest false positive rate. SaaS Defense even finds zero-day threats. Following the acquisition, we worked diligently with our new team members to tailor the product for MSP delivery. According to data from the FBI, phishing has exploded as the number one cybercrime, and it is aimed at theft of login and password credentials. These stolen credentials are used by other cybercriminals to launch large coordinated ransomware attacks. SaaS Defense is based on a novel set of intellectual property that independent testing has shown to be best in class against sophisticated phishing and malware that target Microsoft 365 inboxes, OneDrive, SharePoint, and Teams. It is a robust yet simple to use security solution that eliminates the need for additional MSP headcount or in-depth security training. In addition, it is bundled with our SaaS Protection product, creating a strong margin opportunity for our MSP partners and a low friction purchasing motion. The initial response to SaaS Defense has been outstanding as partners recognize the critical need for email security today, and love that SaaS Defense is highly effective, easy to use, and fits seamlessly with SaaS Protection. SaaS Defense is a first line of security defense, like AV or firewalls, preventing malware from running. In the second line of defense is Datto Ransomware Detection for RMM, which is now deployed on over 1.4 million endpoints, up from over 1 million on our last call. Our solution addresses escalated situations where the attacker has actively bypassed the in-place antivirus or EDR solution, and malware is running on servers or PCs under direct control of the attacker. Without our ransomware detection, each of these events would likely end in ransomware or worse. We are incredibly proud of each save over the past year, and there have been many. We intend to continue to expand our product offerings on the front lines of defense going forward. Now let's talk about the last line of security defense, which is recovery. Our market-leading continuity products have been the last line of defense and security for MSPs and their clients since day one. The importance of bulletproof flexible recovery is only increasing as cyberattacks become more common. As a leader in continuity, we're now doing about 75,000 restores per month and growing. With our Cloud Deletion Defense, we have also performed over 400 complete saves for partners and their clients on the brink of total data loss over the past couple of years. These are scenarios where a cyber attacker locks a client's primary servers with ransomware, then actively erases all backup images, local and cloud, using stolen credentials. In each case, the immutable copies in Datto's cloud saved the day and prevented what could have been a business-ending event for the end client. That brings me to the newest member of the Datto Continuity family, Datto Continuity for Microsoft Azure. We've brought MSPs and the investment community on the development journey all year, so we were thrilled to officially launch it in September. Much like Datto SaaS Defense, the early response from partners has been incredibly energizing. Datto Continuity for Microsoft Azure, or DCMA for short, is a comprehensive business continuity and disaster recovery solution that protects MSPs and their clients' Azure public cloud workloads, providing protection against malicious ransomware attacks, security breaches, server software problems, and cloud outages. We recently announced our strategic partnership with Microsoft, which was key in our development efforts and features a strong co-marketing relationship on DCMA. We believe Datto Continuity for Microsoft Azure is the most secure, highest performing continuity solution in the Azure ecosystem. On top of all this, DCMA is fully integrated into the Datto platform, so MSPs can manage and protect their clients' live applications and data in Azure right alongside workloads in private clouds, on virtual machines, or on premises, all from a single unified platform. Importantly, our DCMA product restores Azure virtual machine images in the Datto cloud, which allows MSPs to get their clients' environments running quickly, even if Azure itself is experiencing a cloud outage. While it's early in the public cloud move for SMBs, worldwide end user spending on public cloud services is forecasted to grow more than 23% this year to greater than $330 billion, according to Gartner. This should prove to be a key growth area for MSPs and Datto for years to come, as MSPs support their clients in the migration to infrastructure as a service, or IaaS. We are now in position with a leading and differentiated solution to help our MSP partners on this journey. Lastly, I will note that applications and data are growing everywhere. In the public cloud led by Azure, but also in private clouds, virtual machines, and on-prem. We're seeing solid continuity growth in all arenas. MSPs are also managing and protecting an increasing share of these SMB digital assets as they continue as an industry to eat into the $1.3 trillion of global SMB IT spend. MSPs are even pushing into co-managed services, partnering with IT departments and enterprise government and EDU clients. Datto's market-leading comprehensive portfolio of continuity solutions allows MSPs to protect digital assets wherever they live. Those were the two major new product announcements in Q3. We continue to have releases every quarter and sometimes every month across our product portfolio. Continuity, RMM, SaaS, PSA, and networking, with a particular focus on security features in each. Security continues to be at the core of everything we do at Datto. We highlighted this recently for MSP partners at our DattoCon event in early October. It was the largest event in our history, attracting more than 4,700 virtual attendees from 50 countries. Our primary message to the MSP community was that they are now on the front line in the global cybersecurity battle. Cybercrime is now a $1 trillion annual drag on the global economy, and the attackers are increasingly finding SMBs to be attractive targets. As the primary provider of IT services for their clients, MSPs are now squarely in the security business. There are two strong implications that follow. First, MSPs will increasingly choose their vendors based on security as the number one product attribute. Going forward, trust in the security of their vendors will matter more than bells and whistles or costs. Second, MSPs have a massive opportunity in providing security solutions to protect their clients and to profit and grow from doing so. For each of these two, we believe we are strongly positioned to be a partner of choice with the best technology solutions in the cybersecurity battle. As a vendor, we anticipate a large return on the years' long investment we have made and will continue to make in internal security. In fact, we announced at DattoCon that we are the only RMM vendor to have passed a stringent security audit called BSIMM, used by a consortium of leading technology and financial companies. We also pointed to a strong development pipeline on security products, which we will bring to market as sell-through offerings that MSPs can use to protect their SMB clients while also finding good margin for themselves. My call to action for MSPs at DattoCon was to define their security stack immediately and improve it over time. Datto will help our partners secure themselves and their clients, both as a trusted advisor and with our innovative products. We will benefit from differentiated, reliable products, our scale, and our persistent focus on security at our core. My DattoCon keynote address, including demos with our engineers of some key security and cloud products, is posted in the investor relations section of our website. DattoCon also featured a keynote from our chief information security officer, MSP interviews, and over a hundred vendor sponsors, consistent with our open ecosystem approach. Building on the security themes from DattoCon, we will offer investors a deeper look into Datto in a few weeks at our first ever investor day on Thursday, December ninth. We have an exciting agenda planned that will give you a better understanding of our products and technology, our unique go-to-market approach with our MSP channel partners, our financial model, and the incredible opportunities we see ahead in securing digital assets. We hope that you can join us. Look for registration information coming soon on our IR website. In summary, we are pleased to have delivered another record quarter and two significant new product launches that align with the MSP industry shift toward a security first approach. We see great momentum across our business today, and we're excited about our strong product cycle that will contribute to growth in 2022 and beyond. We remain well positioned to capitalize on the large and growing opportunity with our current product portfolio and roadmap and the deep trusted MSP relationships that we have built. Finally, I want to thank everyone on the global Datto team for all of your hard work and our MSP partners for their continued support. With that, I'll turn the call over to John. Thank you, Tim, and good afternoon, everyone. We're pleased to report terrific third quarter results today where we outperformed across the board. As I review our numbers, please note that I'll be referring to non-GAAP metrics unless otherwise specified. You can find a reconciliation of non-GAAP measures to GAAP measures in the press release that we issued this afternoon and in the supplemental financials posted on our website. Our third quarter results reflect great momentum across our suite of products and continued acceleration of our business. Third quarter recurring subscription revenue of $146.8 million grew 20% from Q3 last year. Subscription revenue growth has now accelerated every quarter this year. Subscription revenue comprised 93% of our total revenue, which came in at $157.9 million in the quarter, representing 21% year-over-year growth, well above the high end of our previous guidance. Our revenue results reflect a benefit from foreign exchange rates of approximately 1.5%. Strong operating results drove the upside to our guidance, with currency providing less of a tailwind than we had forecasted. ARR at September 30 was $626.7 million, up 20% from $522.8 million a year ago, and nearly a $29 million increase sequentially. We ended the quarter with more than 18,200 MSP partners, a net increase of 400 in the quarter. We grew the number of MSPs contributing over $100,000 in ARR to more than 1,300, a 24% increase from a year ago. Our sell-through model continues to drive strong growth within our installed base of partners. As they roll out data solutions to more SMBs, those SMBs consume more data and seats. They both adopt more Datto products. Our third quarter gross margin of 73% was in line with the strong margin we saw in Q3 2020. Third quarter operating expenses were $80.1 million, a 40% increase from Q3 last year as we continue to invest with a focus on security and cloud to drive revenue growth. As a reminder, expenses reached a low point last year in Q3 when we saw the full quarter impact of the expense reductions we had implemented in response to the COVID crisis. The vast majority of the increase in operating expenses this year was driven by personnel costs. Within OpEx, sales and marketing expenses were $32.8 million, an increase of $8.6 million from Q3 2020 as a result of expanded sales staffing levels as well as higher marketing and sales commission expenses. R&D expenses were $21.5 million, an increase of $6.8 million from Q3 2020, which underscores our continued investment in technology development and security. G&A expenses were $23.6 million, an increase of $8 million over Q3 last year, primarily driven by expenses associated with being a public company and recruiting costs related to increased hiring this year. Finally, depreciation expense within operating expenses was $2.1 million, compared to $2.4 million in Q3 2020. Operating income for the second quarter was $35.8 million compared to $39 million in Q3 2020. Adjusted EBITDA for the quarter, which excludes stock-based compensation, restructuring costs, and transaction-related and other expenses, was $43.8 million compared to $45.8 million in Q3 2020. Our adjusted EBITDA margins were 28%, reflecting continued hiring in the areas of security and cloud, some normalization of travel and return to office expense and costs associated with being a public company. CapEx in the quarter was $11.7 million, and free cash flow was strong again at $20.3 million. Our balance sheet remains very strong, with no debt and approximately $207 million in cash at the end of the quarter. Turning to guidance for the fourth quarter and full year, the increase in our 2021 guidance reflects our positive outlook for the continued acceleration of the business. For the fourth quarter of 2021, revenue is expected to be in the range of $161 million-$163 million. Adjusted EBITDA is expected to be in the range of $38 million-$40 million. Our Q4 total revenue guidance represents year-over-year growth of 16.5% at the midpoint, including a 0.5 percentage point of FX tailwind. We expect subscription revenue growth to be 17.5% at the midpoint. For the full year 2021, we're raising our revenue guidance to a range of $615 million-$617 million. We're also raising our adjusted EBITDA guidance to a range of $174 million-$176 million. Our full-year revenue guidance represents year-over-year growth of approximately 18.5% at the midpoint, including a two percentage point FX tailwind. This is up meaningfully from our prior guidance for full-year growth of 17.5%, which included a 2.5% FX tailwind. We expect subscription revenue to account for over 93% of total revenue in 2021. Capital expenditures for the year are expected to be in the high single-digit percentage range of revenue. As a reminder, for non-GAAP income taxes, we use an effective tax rate of 25%. For calculating EPS, we estimate approximately 168 million fully diluted shares for Q4, and 167 million fully diluted shares for the full year. In closing, we believe our Q3 results and 2021 guidance reflect the ongoing strength of the business. We're very excited about our momentum going into Q4 and look forward to talking more about our business and outlook at our upcoming Investor Day on December ninth. With that, we'll open up the call for questions. Operator? At this time, I would like to remind everyone, in order to ask a question, press star followed by the number one on your telephone keypad. Your first question comes from the line of Sanjit Singh with Morgan Stanley. Your line is open. Thank you for taking the questions. I guess, right off the top, congrats to the team for getting back to 20% ARR growth. You guys were a 20% grower before the pandemic, and to hit that, this level is quite the achievement. Which sort of leads to my next question, which is, kind of bluntly, do you think you can sort of keep it up at these levels, with the sort of major product cycle that you have, you know, that's sort of set to be launched? With that, Tim, you know, if it was another sort of enterprise company that doesn't have the channel model that you guys have, sometimes security slows down the sales cycle. With this big push into security, I'm just trying to see what the impact on the sales cycle at Datto would be relative to a traditional sort of company selling to the enterprise. That's great. Thanks, Sanjit. John's gonna take a shot at the numbers and I'll add something on security. We were really happy to see ARR growth continue to accelerate. That certainly has been the plan. See it hit the 20% mark this quarter was great. Look, we won't draw a line in the sand here today, but you can see a clear trend in the con-
