Analyst · Wells Fargo
Thanks so much, Alex, and good afternoon, everyone. Full details of our third quarter results are available in our shareholder letter. So I'm not going to repeat many of the numbers, but I would like to discuss a few key results and strategic milestones, highlight some aspects of our financial framework to help you understand the fundamentals of the Root model and provide more detail on how we are thinking about the rest of the year. I'll do all of this through the core objective framework that Alex spoke about at the top.
A successful insurance technology business like Root needs to drive significant growth, enhance profitability via loss ratio and retention improvements and optimize customer acquisition via direct marketing and a strong user experience. Across each of these 3 core objectives, our year-to-date trends have improved significantly as our business continues to mature.
Growth is our top priority as it enriches our flywheel with more data. To this end, we posted strong growth during the third quarter and year-to-date periods by all measures that we deem important. We ended the quarter with premiums in force of $600 million, up 41% from last year.
Total policies grew 35%, and average auto premium increased 6% compared to the prior year period. Direct written premiums were $471 million for the 9 months ending September 30, 2020, up 53% versus prior year. And the amount of our policies earned year-to-date, direct earned premium, grew 93% to $450 million compared to the 9 months ending on September 30, 2019.
The 41% growth rate in premiums in force based primarily on strong share expansion in existing markets launched in 2019 or earlier demonstrates the depth of share available in our currently active states. Our team is obsessed with understanding the local factors that drive our customers' decision and allow us to continue to grow in each market we serve.
Now that we have a more mature product informed by millions of customer experiences, we plan to bring Root nationwide. After disciplined expansion into 30 states, we're ready to accelerate that reach. To this end, we are incredibly excited to announce that in November, we closed the acquisition of a shell insurance company with property and casualty licenses in all states, plus the District of Columbia.
With this new access to the vast majority of the U.S. market, our teams are gearing up to launch in new states throughout 2021. We recognize from experience that state expansion requires individualized rate plans, tailored state management and methodical growth. Beyond state expansion, we can further tap into this massive market by addressing the customer's need for insurance holistically.
Although we firmly believe auto is the gateway product, we've recently expanded our offering to include both homeowners and renters as additional tools to building a strong and lasting customer relationship. Protecting our customers' other investments with these additional products is a natural way for us to improve retention and grow our premium base.
Our data-driven edge has been built on the significant volume of rich data fueled by our customer growth. We believe we have a powerful first-mover advantage here, now 5 years in the making, which only strengthens as we continue to grow. Collecting more data enhances our predictive modeling capabilities in a virtuous cycle to power our flywheel. Our proprietary telematics solution integrates driving activity data with actual claims experience and applies our machine learning capabilities to derive precise insight from the growing dataset.
We collect roughly 4 terabytes of rich behavioral data on a daily basis directly from powerful sensors within our customers' smartphones. These sensors allow us to track driving patterns that are most relevant in determining a person's driving ability such as hard braking, abrupt turning and distracted driving. In the third quarter of 2020 alone, we collected an additional 1.5 billion miles of integrated driving and related claims data increasing our total miles collected to more than 14 billion.
But it is not just the number of miles or claims that matters, it is the ability to translate this data into behavioral insights with a high degree of accuracy across hundreds of phone models and then understand how these behaviors cause losses, not explained by other variables. And when they do cause a loss, how much exactly that claim will cost. It's also the ability to improve our business by identifying underwriting and claims fraud and managing our claims cost with real-time data.
Not only are we constantly monitoring and analyzing this rich data internally for the benefit of our proprietary telematics program, but given our commitment to transparency, we now share our cumulative mileage data with the world. As the COVID-19 pandemic began to unfold in early 2020, a we utilized our unique access to real-time driving trends and started providing it for all to see via our website.
This transparency helps our industry answer important questions such as how much driving actually decreased as well as the ways in which driving patterns changed. Beyond a simple mileage measurement, we've been able to gain additional insights through our telematics focus about drivers profiles to more accurately assess their true driving exposure during this unique time.
Our growing data set powers our flywheel and plays right into our second core objective, leveraging our data science expertise to enhance profitability via loss ratio and retention improvements. Through continued improvement in our telematics scoring with the industry's largest and growing data set of behavioral data and claims experience, we are creating a risk segmentation advantage and making auto insurance fairer for consumers.
As our unique approach gains traction and we amass more customers, it improves the overall seasoning of the book and drives down our direct loss ratio over time. Our quarterly results reflect our strong progress in this area. Our direct accident period loss ratio was 85% in the third quarter, a 16-point improvement from 101% in the third quarter of 2019. Meanwhile, our direct loss-adjustment expense was 10% in the third quarter, a 3-point improvement from 13% in the same prior year period.
The increased predictive power of our telematics and our state management program have driven material total direct loss ratio improvements. Through the first 3 quarters of 2019, as we entered 7 new states, only 4 states in our footprint had direct accident period loss ratios below 90%.
Conversely, through the first 3 quarters of 2020, as the predictive power of our telematics improve and we matured in our existing states with only 1 new state launch, a total of 26 states had direct accident period loss ratios below 90% and 21 states were below 80%.
We believe that our first term post telematics underwriting loss ratio compares favorably to first term loss ratios at legacy insurance carriers. However, our total direct loss ratio cannot be compared apples-to-apples against other auto insurance players. Many of whom have been in business for several decades and have less than 20% of their total premiums coming from new customers as opposed to the approximately 50% share of new customers at Root during the trailing 12 months.
Moreover, it is overly simplistic to directly compare a personal auto insurance loss ratio to another personal line like homeowners or renters given massive differences in complexity of rating models, average premiums and retention. Forget about apples-to-apples, comparing auto to home to renters loss ratios is like comparing stake to yogurt to penne, all are nice foods, but they have little else to do with each other.
Finally, our business model is uniquely based upon underwriting out the highest risk drivers due to their disproportionate likelihood to be involved in an accident. In fact, our year-to-date direct loss ratio for the pre-telematics underwriting period is more than 20 points higher than the post-telematics period.
Given the youth of our book and how quickly we are growing, this significantly weighs on the total loss ratio in the short term. We expect to reduce this loss by more rapid identification of high-risk driver characteristics and underwriting out the unacceptable risk as well as improving the lifetime value of customers that we bring into the marketing funnel.
Similar to loss ratio, a mature portfolio will naturally experience higher retention rates at a macro level as the longer customers have been with an insurance provider, the stickier they become. For now, our current portfolio is at a disadvantage in this regard. Also related to maturity is price volatility, which, of course, can also impact retention.
A young insurance company like Root naturally experiences more price volatility as we launch new states, transition to company models for underwriting variables and develop new telematics scores. As we are managing the business for its long-term potential, we believe near-term volatility is always worth absorbing to drive the right long-term decision.
While select markets will experience price volatility as we open new states and address some existing states, we expect price volatility across the book to reduce over time. We are actively targeting retention improvements through product offerings and features, customer engagement via proprietary techniques and customer targeting, which all can drive meaningful improvements in this metric as the portfolio scales and matures.
As an example, the addition of renters and home insurance offers twofold retention improvement potential. First, through cohort mix shift as customers who desire to bundle can now shop with Root; and second, with cross sell. As auto customers with root who add an additional policy have shown to retain approximately 15% better than non-bundled customers at the completion of their first term. Product flexibility includes the ability to easily adjust coverage with one click and even to rejoin Root in a simple new streamlined app feature called Boomerang.
Since testing began earlier this year, Boomerang has successfully reinstated more than 15,000 policies, or the equivalent of 4.7% of our auto policies in force at quarter end. This is a great example of how basic blocking and tackling within our proprietary technology stack can capture meaningful improvements in our unit economics. Our data science-led customer targeting strategies allow us to better identify potential high-frequency shoppers as well as potentially longer retaining customers and pay the appropriate customer acquisition price to drive a target customer mix into our funnel.
Furthermore, we believe claims is the most important moment of truth for our customers and a long-term driver of retention as we build a more mature book of business. Our claims experience is truly differentiated and will allow Root to stand out to customers. From the beginning, we have always built claims with technology in mind, enabling us to handle claims faster and better than any of our competitors. We continue to automate a higher percentage of our claims volume in the third quarter, allowing customers to take pictures of an accident, answer a few questions, and within 24 hours, get a complete resolution and money in their bank accounts. This has improved customer satisfaction as well as reduce both claims and claims handling costs.
So back to that important question, how do we know it's all working? Adjusted gross profit, our key non-GAAP profitability measure shows how our growth, underwriting, maturation of our customer book and capital disciplines come together to generate variable profit and mark our progress towards building a sustainably profitable business.
We measure our progress towards profitability with adjusted gross profit to direct earned premium in order to best capture the contribution margin of our customer revenue. Loss ratio and customer retention are significant drivers in our profitability, and we expect these to improve over time. As our company grows and accumulates more internal loss and premium data, our data science and actuarial teams can construct more accurate predictive models. This is the flywheel at work.
We are now deploying the third iteration of our internal pricing model. Due to the increase in size of our internal data set, this iteration reflects a step-change in our approach, whereby we are able to accurately adjust more rating elements. This in turn allows us to provide fair and more accurate rates to our customers. Insofar as we've improved our loss cost accuracy by about 20%.
Early signs are that the fourth iteration of our pricing model will produce even more substantial benefit once it is deployed. We also expect further improvement in loss adjustment expense. Which we believe already is in line with industry-leading levels and will naturally experience further operating leverage as the business scales and our claims-related technology continues to improve.
Third quarter gross profit was $1 million, and our adjusted gross profit was $10 million. Again, the latter of which is our key profitability measure and was substantially better than a loss of $27 million in the third quarter of 2019 due to an improvement in direct loss ratio, loss-adjustment expense ratio and variable expenses, net of reinsurance ceding commissions.
Adjusted gross profit fully incorporates the work we've done on our reinsurance program, a critical efficiency lever for Root. We set out in 2020 to land the right reinsurance structure for our business today. We're proud to say that beginning July 1 this year, we transfer 70% of our premiums and related losses to reinsurers, while also gaining a 25% commission on written premium to offset some of our upfront and ongoing costs.
This reinsurance program is exactly what we need to allow our equity capital to drive growth and build a deeper moat around our technological advantage, and that's what ultimately matters. Reinsurance has implications for GAAP revenue, and our new reinsurance program will cause a reduction in GAAP revenue versus prior quarters. This is why we use direct earned premium as our primary top line metric for the business. It removes the volatility of our reinsurance program and really captures the revenues received from our customers.
Our third core objective is to optimize customer acquisition via direct marketing and a strong user experience. The structural tailwinds at play, whereby consumers are migrating from agency to direct channels and driving accelerated growth for direct-to-consumer brands leveraging mobile plays right into our hands.
We acquired 75% of our customers through direct mobile channels, driven by our unique onboarding experience that can be completed as fast as 47 seconds, which is highly differentiated and not easily replicated with legacy systems. This is our primary distribution source, our lifeblood. Yet this is only one part of an equation driving a long-term cost of acquisition advantage versus the industry.
Our data-science-led marketing strategy is another vital part of this equation and inherent to the data DNA of Root. We use data-driven targeting strategies across our marketing channels. Our digital distribution model also allows us to be more agile when we see opportunity present itself or, in some cases, slow with caution.
At the onset of COVID-19 in March, we reduced our performance marketing spend, maintaining and monitoring it with a watchful eye during the second quarter. In the third quarter, we resumed pre-COVID levels of marketing spend as we saw signs that the pandemic was accelerating structural shifts in auto insurance that support Root's direct-to-consumer and telematic strategies.
Our third and fourth quarter marketing strategies focus on a test and invest approach as we set the stage for our push into more states in 2021. We are targeting a build-out of new channels such as streaming video to establish a set of diverse acquisition channels that work together.
Additionally, we launched a brand focused campaign in the lead up to the presidential election in an effort to make Root more of a household name. The campaign features NASCAR driver and advocate Bubba Wallace. This work highlights the importance of bold progress and reflects Root's culture and commitment to fair pricing based on driving performance rather than demographics. We are extremely pleased with the positive exposure Root has garnered from this campaign thus far.
At Root, we are always looking for new ways to solve a problem by leveraging technology. While we have a team building a differentiated customer acquisition funnel, the question was posed in the quarter, "What about the customers that we underwrite out? Could we help them find insurance elsewhere and potentially launch a new revenue stream for the company?"
In less than a month, we launched a program to redirect customers with their permission to other carriers. And in so doing, we're able to offset 3% of our customer acquisition spend in the month of October, yet another example of what is possible with the nimble technology infrastructure we have at Root. In the near term, we expect the amplified brand spend will take time to drive acquisition efficiency and could result in temporarily elevated customer acquisition cost levels. However, the longer-term benefit will far outweigh any near term pressure, particularly as we expand our footprint nationally.
I'll close with some thoughts on how we're thinking about the business in year-end 2020 and beyond, and then we will welcome your questions. We will continue to prioritize growth because we believe our business only gets better as more data flows in. Which turns our flywheel and helps to unlock the full potential of our business model. More data allows us to deploy even more advanced algorithms, which allows us to further differentiate our product from the rest of the market while becoming an even better underwriter.
As our flywheel continues to develop, we expect our operational scale will realize economies of scale and grow margins. To be clear, we base all our strategic decision-making on building a business for long-term sustainable growth and profitability. The near-term targets that we're establishing today demonstrate that we are on track in delivering this framework. While 2020 has been a year that few could have expected and no one will soon forget, Root will continue to deliver strong financial results. Our current expectations for the full year of 2020 are as follows: direct earned premium of $595 million to $600 million, adjusted gross profit of $14 million to $16 million.
Root is a long-term focused company and management team. We're excited about our 2020 accomplishment, but even more about what is to come. We'll share our 2021 outlook when we report our Q4 and FY 2020 results in the new year. Until then, we look forward to pounding the virtual pavement actively engaging with our new and prospective investors and keeping you updated on our progress as we continue on this exciting journey together. Operator, please open up the lines for questions.
