Analyst · Michael Nemeroff with Credit Suisse
Thank you, Steve, and to everyone participating on this afternoon's call. I'll begin by summarizing our third quarter results and end by updating our guidance for the remainder of the year before we open the call to questions.
As Steve noted, we had another strong quarter. Alarm.com experienced growth in our domestic business as more of our service providers standardized on the Alarm.com platform and scaled up their operations to drive future growth. And we also continue to add new service provider partners who are now selling Alarm.com's interactive security and automation products and services to their residential and commercial customers.
We also made progress in expanding our rest-of-world footprint and announced new strategic partnerships with international service providers. And the quarter saw us release additional first-to-market products and enhancements to the Alarm.com platform that will enable our service provider partners to grow their businesses in the future.
Before I turn to our financial results, for those of you who are new to the Alarm.com story, I will quickly summarize the components of our revenue. We generate 2 primary sources of revenue. The first is SaaS and license revenue, which is recurring in nature and comprises about 2/3 of our total revenue today. It is also our fastest growing source of revenue. We also generate hardware and other revenue, which contributes about 1/3 of our total revenue. It is principally derived from the sale of hardware that enables the Alarm.com services. In some instances, we selectively choose to design, produce and sell our own proprietary hardware, while in many other instances we integrate hardware produced and sold by our ecosystem partners for use within the Alarm.com platform.
Our third quarter was strong and exceeded our expectations. Total revenue for the third quarter increased 26% over the prior year to $54 million, with SaaS and license revenue contributing the majority of the growth. SaaS and license revenue of $36.2 million, increased 27% over the prior year. The growth in SaaS and license revenue was primarily the result of the year-over-year increase in the total number of our service provider customers who subscribe to the Alarm.com services.
As you heard Steve mention, our service provider partners are standardizing on our offerings and continue to aggressively deploy our technology to their customers, driving growth in their customer base.
We also recognized about $485,000 of SaaS revenue in the current quarter from SecurityTrax and Secure-i, 2 small acquisitions we closed in the fourth quarter of 2014 and the first quarter of 2015. Our SaaS and license revenue renewal rate was 93% for the 12 months ended September 30, 2015. The rate was 94% for the same period in the prior year. Hardware and other revenue of $17.8 million increased 24% over the prior year, resulting from higher sales volumes in most product categories with video cameras sales contributing about half of the overall increase in hard revenue. We are seeing then an increasing percentage of new customers are including our cloud-based video service in their systems.
Hardware revenue for the third quarter was also bolstered by the timing of some orders where our partners build inventory late into the third quarter. We expect that these partners will utilize this hardware in the fourth quarter, and therefore, expect that our fourth quarter hardware revenue will decrease sequentially as it has generally, historically. As we stated in the past, hardware revenues can be lumpy, and this is why we only guide on annual hardware revenue. SaaS and license revenue gross margin was 81% during the quarter, a 200 basis point increase over the prior year, with the margin expansion driven by realizing economies of scale from growth in our subscriber base. Hardware and other revenue margin increased to 26% as compared to 20% in the third quarter of the prior year. Hardware and other revenue gross margins fluctuate from quarter-to-quarter based on product mix.
The increase in hardware margin in the third quarter was partly due to reductions in the cost of certain hardware SKUs, and additionally, we recently implemented improvements to our supply chain logistics, which reduced the carrying costs of some of our products. Our total gross margin for the quarter was 63%, up from 59% in the comparable quarter of the prior year.
Turning to operating expenses, we continue to reinvest the cash flow generated by our core interactive security and automation platform business in North America back into the business. Our investments are primarily in research and development as we continue to hire engineers to accelerate the pace with which we bring new innovative products and services to market. We are also adding headcount and resources as we expand internationally.
Our investments also include developing home and commercial automation platforms as well as energy management solutions for markets adjacent to our core business. We report the results of these businesses in a separate segment in our financial statement.
Total sales and marketing expenses in the quarter increased to $8.4 million and represented 16% of total revenue during the third quarter of 2015, a decrease from 19% of total revenue during the third quarter of the prior year. On a total dollar basis, sales and marketing expenses in the quarter increased 4% over the third quarter of 2014. The increase resulted from additions to headcount to support the growth in our core domestic business as well as international expansion. The increase in compensation expense was partially offset by a decrease in discretionary spending, including advertising events. This was largely attributable to a shift in the timing of our Annual Partner Summit event from the third quarter of 2014 to the fourth quarter of 2015.
General and administrative costs increased 47% to $9.9 million over the comparable quarter of the prior year. The third quarter of 2015 included $3 million of legal expenses related to intellectual property litigation, which we exclude from adjusted EBITDA. The third quarter of 2014 included no legal fees related to litigation. Exclusive of these legal expenses, general and administrative costs were $6.9 million in the quarter, an increase of 3% over the prior year and represented 13% of total revenue in the third quarter of 2015, a decrease from 16% of total revenue in the same quarter of 2014.
The 3% increase in total G&A expense resulted from higher rent expense as our headcount increased company wide as well as a small increase in personnel and G&A-related functions.
Research and development expense was $9.8 million in the quarter. This is a 61% increase over the prior year and represented 18% of third quarter total revenue as compared to 14% of total revenue in the third quarter of 2014. The growth in total R&D expense was driven by compensation expense as we continue to hire into engineering and other R&D-related functions. The total number of employees in research and development grew to 247 on September 30, 2015, as compared to 164 employees on September 30, 2014. As I mentioned last quarter, we plan to continue to increase our investment in R&D throughout the remainder of 2015 to extend our leadership position in the development of smart home and enterprise technology.
Total operating expenses, excluding amortization and depreciation, increased to $28.2 million in the third quarter of 2015, or a 35% increase over the prior year. On an adjusted basis, excluding stock-based compensation, amortization and depreciation and legal fees related to intellectual property litigation, total operating expenses increased to $24.4 million, which is a 21% increase over the prior year. On the same adjusted basis, total operating expenses represented 45% of total revenue during the third quarter as compared to 47% of total revenue in the third quarter of 2014.
Adjusted EBITDA improved to $9.7 million as compared to $5.1 million in Q3 2014. Adjusted EBITDA represented 18% of total revenue in the third quarter as compared to 12% of total revenue in the third quarter 2014. The growth in adjusted EBITDA and margin resulted primarily from the year-over-year growth in SaaS and license revenue and higher associated gross profit and to a lesser extent, from the increasing gross profit on hardware and other revenue.
Leverage in certain operating expenses also contributed to the increase in adjusted EBITDA, specifically in general and administrative costs. A decrease in sales and marketing expenses as a percent of revenue in the quarter also contributed to the increase in adjusted EBITDA. However, marketing initiatives vary from quarter-to-quarter, and we expect to increase our marketing spend in the fourth quarter of 2015.
That said, our efficient go-to-market approach of partnering with our service provider partners should be a source of sales and marketing leverage in our core business over time.
We ended the quarter with cash and cash equivalents of $126.6 million, up from $20.9 million as of June 30, 2015. The company raised $98 million in net proceeds from its initial public offering, which closed in July 2015. The company generated $13.5 million in cash flow from operations during the quarter, an increase of $13.6 million over the third quarter of 2014. The increase was primarily due to the timing of payments for trade payables and other liabilities and to a lesser extent, cash collections and accounts receivable and an increase in net income and noncash charges.
Capital expenditures of $4.5 million during the quarter increased from $3.9 million during the same quarter of 2014. Over 2/3 of our capital expenditures in the quarter were subsidized by buildout incentives related to the buildout of our new office space.
I'll conclude by providing our guidance for the remainder of the year. We are raising our full year 2015 total revenue guidance to a range of $197.7 million to $200.1 million as compared to the previous guidance range of $193.9 million to $195.3 million.
Full year SaaS and license revenue expectations are being raised to a range of $139.9 million to $140.1 million or $37.7 million to $37.9 million in the fourth quarter of 2015.
We're also raising our hardware and other revenue guidance now forecasted to be between $57.8 million and $60 million for 2015. Our expectations for full year 2015 adjusted EBITDA are being raised to a range of $27.7 million to $29.1 million versus our previous guidance range of $20.3 million to $21.3 million. The increase in our annual adjusted EBITDA guidance also reflects about a 3% increase in our expectations for full year 2015 adjusted EBITDA margins. Note that while we are significantly raising full year adjusted EBITDA guidance, we do expect that Q4 will show sequentially lower adjusted EBITDA versus Q3 as we continue to execute our plan to increase our R&D spending and product development capability.
Fourth quarter R&D costs will increase from the significant number of university engineering and other technical role hires that began their employment with the company in late August and September.
Additionally, fourth quarter marketing expenses will increase sequentially over Q3 by approximately $1 million, in large part due to the shift in the timing of our Annual Partners Summit event into the fourth quarter, as I previously mentioned.
Non-GAAP adjusted net income for the full year guidance is raised to an estimate of $14.9 million to $15.6 million, and our non-GAAP adjusted net income attributable to common stockholders is also raised to a range of $5.2 million to $5.4 million or $0.20, $0.21 per diluted share based on an estimate of 26.5 million weighted average diluted shares outstanding.
We project full year 2015 stock-based compensation expense of about $3.8 million, and our full year tax rate is expected to be approximately 37%.
In summary, we are pleased with our third quarter results, and our outlook for the remainder of 2015 is positive as reflected in our updated guidance. We will now turn the call over to the operator for Q&A.
