Good afternoon, and thanks for joining us today. Let's dive right in and review the second quarter. After Alan and I give our overviews, we'll be happy to take your questions. Before we discuss the second quarter, I want to just take a moment to tell you how ShotSpotter is doing in general. Even though we have a tremendous amount of work to do, I'm happy to report that we're doing quite well. This is an exciting time for us here at the midpoint of 2022. Not only is this our fifth year anniversary as a public company, it's also nearly two years into our effort to accelerate the company's revenue and profit growth through the build-out of our precision policing platform.
As most of you know, this strategy was inspired by our goal to provide value and impact beyond acoustic gunshot detection into adjacent capabilities, including investigative and AI-based analysis tools. We now have several quarters under our belt, and based on our experience to date, we believe the decision to build out this broader platform in order to grow our revenue and TAM opportunity was strategically sound. We're seeing that with the steady growth of our core gunshot detection customer base and coverage footprint, and we're seeing it with the emerging adoption and growing interest from the market in our multi-product solution set. ShotSpotter is a critical solution provider to law enforcement agencies around the country. Customer insight and intimacy is our currency.
We know many of the key decision-makers in law enforcement and are intimately familiar with the funding and political environment in which they operate, and we know how their needs are changing, and we are grateful for their trust in our ability to meet those needs. Our strong execution on a tactical basis was evident in Q2. We reported revenue of $20 million, up 37% from $14.6 million a year ago. GAAP net income was $3 million, or $0.24 per diluted share in Q2 this year, compared to a GAAP net loss of $250 thousand for Q2 last year. Our adjusted EBITDA was $4.1 million at 20% margin this quarter, which was an increase of 39% from the $2.9 million in the second quarter of 2021.
Let's specifically review ShotSpotter Respond's momentum. We went live in four new cities during the quarter: Perris, California, North Miami Beach, Florida, Cape Girardeau, Missouri, and Forest City, Arkansas. We also saw expansions in six current customer coverage areas. This traction looks like it will continue into the second half of 2022, with 12 new cities and 8 expansions that are already contracted and being deployed to go live this year. Our international presence also continues to grow, with two new recently contracted deployments in process with Cape Town, South Africa, and an expansion in the Bahamas. As many of you know, selling to government entities is complex and can create slightly longer sales cycles.
The good news is our customers have funded mandates, they do not go out of business, and they tend to be quite loyal once you've earned their trust through consistent performance and execution. This provides an opportunity for long-duration revenues that are extraordinarily sticky with low churn. In the first half of this year, we secured multi-year contracts in 68% of our new mile bookings, and more than 25% of our renewal bookings were multi-year, and 52% of total renewals included a price increase. Clearly, we're pleased with the continuing adoption and expansion of Respond and also the stickiness. We had zero attrition year - to - date and anticipate close to zero attrition for the remainder of 2022. Respond, of course, is a core product offering, but we're equally delighted with the growing interest in pipeline build of our other solutions in our platform.
COPLINK X, which we are currently marketing and selling through our Forensic Logic acquisition, has been in our portfolio only for a few months, but we're already seeing lots of inquiries and requests for demonstrations of how this cloud-based data source can be integrated into our customers' daily investigative work. We recently received an award of a seven-figure ARR deal from a state agency that we expect to take live in Q4 of this year. We're really quite bullish on this part of our platform being a significant growth driver for the company in 2023 and beyond. In the second quarter, we also saw very encouraging progress with ShotSpotter Investigate, our fully functional case management system.
In Q2, we introduced ShotSpotter GCM, or Gun Crime Management, which automates much of the inputting, coding, and tagging of the data from gunfire incidents that we identify and report out to our customers. We built this capability in-house, leveraging our existing expertise and experience, and developed it to integrate with the other crime management and analysis applications available on our platform. Because we work so closely with our customers, we know this is the capability that they will value as it enhances the utility of our overall solutions. We're feeling quite confident about ShotSpotter as we enter the second half of 2022 and lay the foundation for 2023 growth and beyond. At a macro level, we're seeing a pronounced and measurable uptick in crime, along with increased pressure for law enforcement transparency.
At the same time, and this cannot be underestimated, police departments are struggling to maintain full staffing to address the increasing demands for service and accountability. According to the May 2021 Occupational Employment and Wage Statistics report conducted by the Bureau of Labor Statistics, in 2020, the number of police officers employed nationwide declined 1.6%. This is the first time this has happened in over a decade. Increased funding through healthier federal, state, and municipal budgets, while constructive, will not be enough to bridge the gap. We believe this creates strong structural tailwinds for the adoption of technology solutions that drive smarter, intelligent-led strategies, leading to more efficient, effective, and equitable community policing.
We're extremely proud to have been successful in keeping our momentum through a global pandemic, fears of an impending recession, supply chain constraints, and inaccurate reporting about our company. Despite those challenges, we continue to persevere, and we believe we are right on track to execute on the significant opportunity ahead of us. Alan will go through the numbers in more detail, but looking forward, we're maintaining our full year revenue guidance for 2022 at $81 million-$83 million, which is 41% year-over-year growth at the midpoint. Our adjusted EBITDA margin guidance also remains at the previously guided 19%-21% of our forecasted revenues for 2022. One bit of non-operating news worth mentioning is that the judge in our defamation suit against Vice Media did grant their motion to dismiss.
While we're disappointed in that decision, we are pleased that Vice Media, even after the dismissal, has stepped up and agreed to do the right thing. They have publicly corrected the record on key misstatements, which were at the heart of our defamation suit in the first place. They have now joined the Associated Press and several other publications to repudiate the false narrative that ShotSpotter had somehow engaged in tampering with evidence at the behest of law enforcement. We believe we made the appropriate decision to defend ourselves and our customers by pursuing our defamation complaint, which, by the way, provided a critical venue for us to correct the record. However, we're now pleased to put this unfortunate matter behind us and focus on our work of saving lives, helping communities become safer, and doing work that matters. Alan, over to you.
Thank you, Ralph. We're very pleased with our performance in the second quarter. As Ralph mentioned, this quarter we went live in four new Respond cities and expanded in six current cities. We are seeing an increase in the interest of our solutions. In fact, we already have 20 new Respond contracts executed. Of these, 12 are contracts with new cities, and eight are expansions with current customers. Ralph also mentioned our two new international contracts. This is the highest level of new contracts that we have had at any earnings release since going public. In fact, several of them have already gone live since the end of the second quarter. Let me provide more details on the quarter, and then I will share some thoughts around the balance of the year.
Second quarter revenues were slightly ahead of expectations at $20 million, a 37% increase over the $14.6 million in the second quarter of 2021. Revenue increased as our deployed miles are up year - over - year, and we also had a higher level of professional services in our LEEDS division. Gross profit for the second quarter of 2022 was $11.6 million or 58% of revenue versus $8.3 million or 57% of revenue for the prior year period. Gross margin may continue to be impacted to a slight small extent as we continue to replace 3G sensors throughout the end of the year.
We also saw impressive growth in adjusted EBITDA for the second quarter, which was $4.1 million, a 39% increase from the $2.9 million in the second quarter of 2021. As a reminder, adjusted EBITDA, a non-GAAP financial measure, is calculated by taking our GAAP net income and adjusting out interest income taxes, depreciation, amortization, stock-based compensation expenses, and acquisition-related expenses, including adjustments to our contingent consideration obligation. Turning to our expenses. Our operating expenses for the second quarter were $8.4 million or 42% of revenues versus $8.5 million or 57% of revenues in the second quarter of 2021. Operating expenses includemd higher personnel related costs as well as costs associated with Forensic Logic, which was acquired in January 2022.
That said, operating expenses for the second quarter were offset by a contingent consideration adjustment, a reduction of approximately $3.4 million related to the potential earn-out payments associated with our Forensic Logic acquisition, which have been reduced for 2022 but increased for 2023 due to a delay in some expected contracts. Breaking down our expenses, sales and marketing expense for the second quarter was $5.8 million, or 29% of total revenue, versus $3.9 million or 27% of total revenue for the prior year period. Our sales and marketing teams continue to build our sales pipelines and expand our marketing efforts. We continue to focus on maintaining high levels of customer satisfaction, which helps keep our attrition rate low.
Our R&D expenses for the second quarter were $2.5 million, or 13% of total revenue, compared to $1.7 million, or 12% of total revenue for the prior year period. We continue to invest in increasing the functionality of all of our products. G&A expenses for the quarter were approximately $100,000, or less than 1% of total revenue, compared to $2.8 million, or 19% of total revenue for the prior year period. The reduction in G&A expenses was primarily related to the offset from the contingent consideration adjustment related to the Forensic Logic earn-out expectations. We expect our G&A expenses will continue to increase in both percentage of revenue and in absolute dollars as our company grows.
For the third and fourth quarters, we expect it will increase as a percentage of revenues from what we experienced in the second quarter. Our GAAP net income was $3 million, or $0.25 per basic share, and $0.24 per diluted share for the quarter based on 12.1 millio n and 12.3 million basic and diluted weighted average shares outstanding, respectively. This compares to a loss of $250,000 or a loss of $0.02 per share based on 11.6 million basic and diluted weighted average shares outstanding for the prior year period. Our adjusted net income for the second quarter was a loss of $427,000 or a loss of $0.04 per share based on 12.1 million basic and diluted weighted average shares outstanding.
This compares to a loss of $244,000 or a loss of $0.02 per share based on 11.6 million basic and diluted weighted average shares outstanding for the prior year period. Adjusted net income, a non-GAAP financial measure, is calculated by taking our GAAP net income and adding back acquisition related expenses, including adjustments to our contingent consideration obligation. Deferred revenue at the end of the quarter increased to $35.8 million from $26.7 million at the end of Q4 2021, and the increase was primarily related to our growth in revenues and the addition of Forensic Logic deferred revenue. We ended the quarter with $3.4 million in cash and cash equivalents versus $15.6 million at the end of fourth quarter 2021.
The decrease is primarily related to almost $28 million in accounts receivable that we had at the end of the second quarter, much of which has already been collected. Our current cash balance is greater than $14 million. During the second quarter, we also repurchased 49,369 of our shares at an average price of $29.35 for approximately $1.45 million. We have approximately $15 million available on our line of credit if ever needed. While the actual line of credit is still $20 million, we did issue a $5 million letter of credit related to one of our customers contract requirements. That said, this issued letter of credit does not actually add any debt, so we still have no short or long term debt outstanding.
Turning to our full year 2022 outlook, we are maintaining our full year revenue guidance at $81 million-$83 million, and we are maintaining our expected adjusted EBITDA margin at 19%-21%. Now back to you, Ralph, for some final thoughts, and then we'll be happy to take your questions.
Thanks, Alan. In closing, we believe that we have the wind at our back operationally with very constructive macro market trends. Our annual revenue rate is strong and durable. Our unit economics are compelling, and we believe we have developed a large and sustainable competitive moat. In addition, our scale and operational efficiency continue to expand. Here at the midpoint of 2022, we're feeling quite optimistic, not only for a strong finish for the year, but also a robust and quick start into 2023. With that, let's open it up for questions.
Ladies and gentlemen, at this time, we'll begin the question and answer session. To ask a question, you may press star and then one using a touch-tone telephone. To withdraw your questions, you may press star and two. If you are using a speakerphone, we do ask that you please pick up the handset prior to pressing the keys to ensure the best sound quality. Once again, that is star and then one to join the question queue. We'll pause momentarily to assemble the roster. Our first question today comes from Richard Baldry from Roth Capital Partners. Please go ahead with your question.
Thanks. I know you've, you know, announced you've got a large number of contracted deals for the second half. I think you said 12 new cities and eight expansions. I'm curious if you can talk about the pipeline outside of that you know, would obviously impact more either fourth quarter if they close soon or more like 2023, how you feel about that given the large number of wins you've had both in the first half and already signed for the second half. Thanks.
Yeah. Thanks for that question. Maybe I'll start and Alan, jump in as appropriate. We're actually feeling quite bullish about our bookings momentum, just not with Respond. There's some additional bookings that we expect to happen outside the ones that we referenced in our earnings report here. We're continuing to see very strong pipeline build with our Connect solution and Investigate. I think we talked a little bit about a fairly large booking transaction we had through our Forensic Logic acquisition with COPLINK X that we're expecting some additional traction there. It's gonna be a very busy second half for us this year, and I think that's what gives us a lot of confidence about how we're gonna be thinking about 2023 and beyond.
Could you maybe talk about whether any of the deals that you've won or that are ahead have managed to tap any new funding sources, whether that's, you know, federal set-asides in legislation or earmarks successfully used?
Yeah. It's a fabric of funding sources that's all over the place. A lot of it's being driven by municipal budget health, but there's also some fairly robust support coming in from the federal government. We also just have continued support from the president that refers to acoustic gunshot detection technology as being a viable solution to use some of these funding streams available, that he's making available to address violent crime.
Maybe last one for me. I guess I assume that there was still some litigation costs in the second quarter. Can you talk about sort of the scale of that and if that all comes out for the third quarter and the second half, or if there's any residual sort of mopping up of those expenses? Thanks.
Yeah. This is Alan, so I'll take that and Ralph you can add as well. There were definitely legal expenses in the second quarter from a GAAP basis, though it was less than what we had in the first quarter. We did continue a little bit into Q3, as you expect, where we were finalizing the final things with Vice. Those expenses are in for at least one month, but we do expect that our legal expenses are gonna go down in Q3 and Q4 based on what we know right now.
Great. Thanks for the great start to the year.
Thank you.
Once again, if you would like to ask a question, please press star and then one. To withdraw your questions, you may press star and two. Our next question comes from Matt Pfau from William Blair. Please go ahead with your question.
Hey, guys. Thanks for taking my question. Wanted to ask on the pipeline and how do you feel about your ability to get those deals implemented this year, particularly given it's more backlogged than you've had historically as a public company?
You wanna take that, Alan?
Yeah. Yeah. Sure. This is Alan. I think we certainly feel really good about the fact they're already signed, so that's great. We are working. Some have already gone live. Some of those are smaller contracts, might be a Tier 4 or Tier 5, so maybe 1 or 2 miles. Those may go a little faster. The rest of them, sometimes it's a little hard to tell when we get the access to to hang the sensors exactly how fast we'll be able to go live with those. But you know, we've already said that we're expecting to go live north of 120 miles by the end of the year. We still believe that to be true. But the contracts that we have already signed are going to help us get there.
Again, until we actually get them live, you know, we can't recognize the revenue. We'll see how that goes. The entire team is working hard to make sure we can go as fast as we can on those because we have more in the pipeline that are gonna get signed as well as the year goes on.
Yeah. I think I would just add, Alan, that we're not seeing any supply chain constraints that would prevent us from a materials point of view to be able to accomplish the 120+ miles this year.
That's correct. Mm-hmm.
Okay. Great. Then I wanted to follow up on the comments around Forensic Logic and the COPLINK X product. You cited you're seeing good demand there, and you called out the win with the state of Massachusetts. There were also some comments on the contingent consideration around some delays. Just maybe a little bit more detail on, you know, what's going on in that business, both on the positive side and then on the delay side as well.
Sure. This is Alan. I'll start, and then, you know, Ralph can add too. You may recall that when we went into the year, we expected to get about $6 million in ARR related to the Forensic Logic acquisition. We will be north of that. We've also, though, not mentioned exactly what is required to get the earn-out considerations for both 2022 and 2023. They are getting new contracts. They might be just a little later than we would have expected for them to get a higher amount of the 2022 earn-out expectation, but it also increases the expectation that they'll get a little more revenue in 2023.
Okay. Great. Thanks, guys, for taking my questions. Appreciate it.
Sure.
Ladies and gentlemen, seeing no additional questions, we'll end today's question-and-answer session. If your question was not taken, you may contact ShotSpotter's investor relations team by emailing ssti@gatewayir.com. I'd now like to turn the floor back over to Mr. Clark for closing remarks.
Great. Thank you very much for that. Really appreciate everyone dialing in. As Alan and I discussed, we're having a tremendous year this year and expect to finish out very strong. Appreciate your interest and looking forward to chatting with many of you on our follow-on calls.
Ladies and gentlemen, with that, we will conclude today's conference call. We thank you for joining us today. You may now disconnect your lines.
