David Hornik - Director

Thanks, Vern. Hi, everyone and thank you for joining us today. As you may have seen from the press release we issued this afternoon, I am thrilled to share that after a broad and extensive search to identify the company's next leader, Todd Nightingale has been appointed our next Chief Executive Officer of Fastly. Fastly's large enterprise customer base, robust product roadmap and unrivaled customer satisfaction gives us confidence about Fastly's future and the significant opportunities ahead. As we search for the company's next leader, the Board was committed to finding a candidate that could help build upon Fastly's strong foundation and lead it into the next stage of growth.

The Board is confident that Todd's customer-oriented leadership style and extensive background helping customers transform their infrastructure and digitize their businesses will greatly benefit Fastly and position the company for future success. Hailing from Cisco, where he currently serves as Executive Vice President and General Manager of Enterprise Networking and Cloud, Todd is a proven and passionate technology leader. Todd understands that now more than ever, enterprises need innovative solutions that enable them to deliver globally performing, secure and reliable applications to their customers. He will officially join us as CEO on September 1 and Joshua will remain with the company for a period of time to ensure a smooth and successful transition.

Please note that at this time, we won't be addressing any questions regarding Todd's appointment during today's Q&A but we'll plan to share more information after it's started.

With that, I'll turn the call over to Joshua.

Joshua Bixby - Chief Executive Officer

Thank you, David. Hi, everyone and thanks for joining us today. Today, I will talk about the quarter and then we will invite Ron to provide some more color on this quarter's results. Then we will take some questions which, as David indicated, we ask that you focus on the results and the outlook.

In the second quarter 2022, we reported revenue of $102.5 million, representing flat sequential growth and 21% growth year-over-year. These results exceeded the top end of our guidance range of $99 million to $102 million and represent another record revenue quarter. Our customer retention and growth engine remains strong. Our LTM NRR was 117% and our DBNER was 120% in the second quarter. Our average enterprise customer spend was $730,000, representing a 1% quarter-over-quarter increase. Our total customer count in the second quarter was 2,894 of which 471 were enterprise customers. Our total customer count increased by 14 in Q2, down from 76 in Q1. Our total customer count was impacted by higher churn at the low end of our customer base which we believe was impacted by the uncertain macro environment impacting smaller customers and the dynamics we have described before in which small customers opt for our more robust developer-friendly trials.

We continue to focus on landing new enterprise and large customers. For example, in the second quarter, the average monthly revenue run rate of the new customers we added to the platform was 85% higher than those that churned. In terms of developer traction, we added over 100,000 developers to our platform across Glitch and our Compute@Edge platform and we are pleased to see so many new developers experimenting with us. It is encouraging to see our enterprise customer count increased by 14 compared to 12 in the first quarter. This increase in enterprise customers validates our efforts in sales and marketing to retain and expand our customers' revenue, particularly focused on larger customers. This was the case with 2 Fortune 500 customers, one, a leading CRM company with world-class enterprise customers and the other a global digital payments juggernaut. Both customers expanded their use of Fastly across multiple product lines in the second quarter.

You may have seen the announcement last week that Fastly is now an official global sponsor of the Mercedes AMG Petronas Formula One team. This long-term partnership reflects our shared commitment to experiences that are fast, safe and leading edge, both on the track and on the Internet. You will be hearing more about this growing relationship on the track and on our platform in the coming quarters.

As we discussed in detail last quarter, one of the key initiatives we have undertaken in 2022 is the deployment of our new architecture for key metro regions. As previously discussed, we believe we will achieve material gross margin leverage by doubling down our efforts on server efficiency with this new architecture which is coupled to our proprietary software development. As discussed previously, we have been running duplicate sites which is a gross margin headwind. However, our gross margin in the second quarter was further adversely impacted primarily by onetime cost true-ups and other smaller items. Ron will provide more details in his section as well as our strategic initiatives at reducing supply chain risks and carrying costs on our infrastructure capex. Our gross margin declines are an area of focus and we remain committed to taking the necessary steps to see this improve. Like last quarter, the pricing dynamics in the business have not materially changed and have not been a major contributor to our recent decline.

The team at Fastly remains united in our common mission which is to fuel the next modern digital experience by providing developers with a programmable, secure and reliable edge cloud network that they adopt as their own. Central to this common mission is the key role developers play in our journey and the new and expanding power of distributed edge compute and security. As they use our trusted platform, they become more interested in its features and that keeps them engaged and retained as customers as they scale. To reinforce this effort, we have acquired Glitch, announced on the heels of our Q1 results, a platform of 1.8 million developers, bringing together two of the world's best ecosystems for application development into a single seamless developer experience to deliver globally performance, secure and reliable applications at scale. Now developers can innovate, create and share full stack web apps without having to run the infrastructure or manage tools themselves. We are very excited about Glitch as it provides a giant leap forward in our developer relations efforts.

We are also building partner momentum to broaden and deepen our developer reach. As you may have seen last week, we announced a reseller partnership with HUMAN to resell their industry-leading bot detection to help security and fraud teams keep cybercriminals out of their online applications and services. Using superior detection methods, hacker intelligence and collective protection across the web, HUMAN detects and defeats bot attacks and fraud with unmatched scale, speed and precision. Now customers can get all the benefits of Fastly's next-gen WAF, the first and only unified WAF solution with HUMAN's exceptional bot protection management capabilities. In the coming quarters, we will continue to expand our roster of partners to expand the scope and reach of our platform.

Moving on to our product highlights for the second quarter. Our delivery products which are part of our network services portfolio continued to receive strong market validation. Fastly was recognized as a customer choice in the 2022 Gartner Peer Insights Voice of the Customer Global CDN. Fastly received the highest customer rating of 4.8 out of 5 stars and the highest customer willingness to recommend at 97%. We earn recognition due to our network size and scale, developer focus, web security and customer support. Positive customer sentiment continues to lead to significant up-sells with our largest customers. For example, in the second quarter, a leading social media platform with over 50 million daily active users chose to expand our relationship with additional products after undertaking a competitive RFP process.

We continue to accelerate Fastly's product delivery. In the second quarter, we had 14 releases in total compared to 11 releases in the first quarter. Observability has been a top priority in 2022 and we announced general availability of both Origin Inspector and Domain Inspector which both can be self-enabled straight from the Fastly UI. For companies using a single origin, multi-cloud or multi-CDN architecture, Origin Inspector unlocks end-to-end visibility of Internet traffic traveling from the origin to the Fastly edge cloud. Domain Inspector allows our customers to effortlessly monitor traffic for a single fully qualified domain name or multiple domains assigned to a Fastly service.

On the security front, we had several new developments. Fastly's next-gen WAF edge deployment is now in general availability. Given the rise of new threats in late 2021 and into early 2022, such as Log4J and Spring Shell, we added new APIs for deprovisioning, improved origin sinking and now support the percentage ramp-up feature to control the amount of traffic through the edge security service. Our delivery customers are easily migrating to our expanded security offering. In the second quarter, an online discovery platform serving over 300 billion content recommendations monthly extended its Fastly edge delivery needs with the Next-Gen WAF product.

Along with Fastly's next-gen WAF, we added CBE signals, allowing virtual patching functionality to be configured through a web interface. We introduced Fastly Security Labs, a new program that empowers customers to be the first to test new detection and security features directly to the security product team, bolstering the quality of our Next-Gen WAF. We also added features to our image Optimizer and we added JavaScript SDK to Compute@Edge supported languages. Compute@Edge continues to be critical in winning new business. For example, a Japanese e-commerce marketplace, chose Fastly specifically because of our JavaScript support in a competitive deal for Compute@Edge that did not include delivery. Our continued strong execution on the product and engineering front is very exciting and our significant increase in release velocity reinforces our commitment to developers and platform builders.

Underpinning all of our technology is our lightning fast network. We continue to remain consistently faster than our peers in the U.S. and Europe, even surpassing some of our toughest critics and customers' expectations. This performance advantage validates our unique architecture and we are continuing to invest in this development to fuel growth. Performance paired with security is one of the most critical decision-making metrics for our customers. That is why we are excited and proud to be part of Apple's new iCloud private relay service that's designed to protect users' privacy on the Internet. And we're also collaborating with Apple, Google and others to develop and standardize the technology behind private access tokens to provide secure anonymity to end users.

I will close out by saying that working closely with world class customers like Apple is further validation of Fastly's technology and platform solution and we look forward to further opportunities to collaborate with industry leaders.

To discuss the financial details of the quarter and guidance, I now turn the call over to Ron. Ron?

Ron Kisling - Chief Financial Officer

Thank you, Joshua and thanks everyone for joining us. Today, I will discuss our business metrics and financial results and then review our forward guidance. Note that unless otherwise stated, all financial results in my discussion are non-GAAP-based metrics.

Total revenue for the second quarter increased 21% year-over-year to $102.5 million, exceeding the top end of our guidance of $99 million to $102 million. In the second quarter, revenue from Signal Sciences products was 13% of revenue, a 56% year-over-year increase or 41% increase after purchase price adjustments related to deferred revenue are reflected. While we are not immune to the macroeconomic trends, we are seeing healthy traffic expansion from our enterprise customers and given our relatively smaller market share, we are benefiting from share gains in an otherwise challenging environment. Our dollar-based net expansion rate, or DBNER, was 120%, up slightly from 118% in Q1 and our trailing 12-month net retention rate was 117% up slightly from 115% in the prior quarter. We continue to experience very low churn of less than 1% and our customer retention dynamics remain strong.

As Joshua stated, we had 2,894 customers at the end of Q2, of which 471 were classified as enterprise, those customers with an excess of $100,000 of revenue over the previous 12 months. Enterprise customers accounted for 88% of total revenue on a trailing 12-month basis, down slightly from their 89% contribution in Q1 and increased their average spend to $730,000 from $722,000 in the previous quarter, demonstrating our continued ability to expand our business within our largest customers and our strong customer retention. Our top 10 customers comprised 34% of our total revenues in the second quarter of 2022, in line with their contribution in the first quarter of 2022.

Before I begin a detailed discussion of our financial performance, let me step back and take a moment to discuss the changes taking place within Fastly's financial organization. As we have discussed, since I joined Fastly 1 year ago, we have been in the process of transforming our financial team, our operations and the management of our balance sheet. This has resulted in several changes that we believe will not only strengthen Fastly's financial position longer term but also improve faster competitive positioning and its transparency to the investor community.

Let me briefly discuss these improvements. First, we used our strong cash balance to repurchase approximately $235 million of the principal amount of our convertible debt at a 25% discount to its principal value resulting in a $54 million gain on this repurchase. Secondly, we made advanced payments for capital hardware of $29.3 million to suppliers on purchase commitments we had made in early 2021 to reduce our exposure to supply chain constraints. These advanced payments will reduce carrying costs by over $1 million over the next 12 months depending on our deployment schedule of the committed equipment.

Third, we have improved our capacity planning process with better forecasting and cross-functional reviews to better align capacity investments with expected traffic levels. We believe this will result in improved gross margins in the medium to long term. In addition, we now expect our cash capex for 2022 which includes purchases of PP&E and capitalized internal use software and excludes advanced payments for PP&E and repayments of finance leases to decline to a range of 10% to 12% and from our previously expected range of 12% to 14%.

Fourth, we have improved our controls around cost of revenues and made adjustments to our accounting for free developer and charitable organization accounts and recorded a onetime Q1 true-up to our cost of revenues of approximately 160 basis points in the second quarter. And lastly, for the second half, we have put in place additional controls around hiring and non-headcount spending. As we previously shared, our expenses in 2022 were weighted to the first half of the year. And with these adjustments, we expect second half operating expenses to decline as compared to the first half. In addition, as we improved our cost controls, we experienced some onetime true-up of costs in the second quarter, primarily in sales and marketing.

I will now turn to the rest of our financial results for the second quarter. Our gross margin was 50.4% for the second quarter compared to 52.6% in the first quarter of 2022. This gross margin is below the flattish sequential level we anticipated during our last quarterly earnings call. This is primarily due to a onetime true-up to our cost of revenue I discussed above as well as other smaller onetime items that, had they not occurred, would have led to an approximate decline of only 50 basis points sequentially. We realized the optics of this gross margin trend are unfavorable and I want to confirm that we did not see any meaningful decrease in our pricing in Q2 compared to the first quarter. And our prior discussion on our network investments in the next-generation architecture remains intact and we expect gross margin improvement in the second half. We continue to expect gross margin to increase meaningfully for the remainder of 2022 towards the low to mid-50s.

Operating expenses were $78.6 million in the second quarter, up 18% over Q2 2021 due to increased headcount across the organization, higher-than-expected salary increases, an acceleration in T&E expenses, increased investment in product and go-to-market activities and as I previously mentioned, certain one-time expense items. We experienced several one-time expense items in Q2, primarily in sales and marketing that we do not expect to repeat in the second half of 2022. A little over half of the quarter-to-quarter increase in opex was due to one-time expense items in the quarter.

While we now anticipate operating expenses for 2022 to be higher than we planned at the beginning of the year, as we previously stated, we still expect expenses to be lower in the second half as compared to the first half. Our operating loss for the quarter was $26.9 million and our net loss was $28 million or a $0.23 loss per basic and diluted share compared to an operating loss of $17.6 million, a net loss of $17.4 million and a $0.15 loss per basic and diluted share in Q2 2021.

Turning to the balance sheet, we ended the quarter with approximately $767 million in cash, cash equivalents, marketable securities and investments, including those classified as long term. During the quarter, we repurchased $235 million in aggregate principal amount of our convertible debt for $176.4 million or $0.75 on the dollar before related fees and transaction costs, reducing our debt balance to $703 million from $934 million. We will continue to use our balance sheet strategically to capitalize on low-risk opportunities that arise in the capital markets during these volatile periods.

Our free cash flow reflects the impact of the advanced payments on capital equipment commitments of $29.3 million, capital expenditures of $15 million which include cash purchases of capital equipment, capitalized internal use software and payments on finance leases in the quarter, resulting in the decrease in free cash flow to negative $61 million. Our cash capital expenditures were 11% of revenue in the second quarter and our capital expenditures include capitalized software. This, along with our foundational technology drives efficiency and leverage in our network which is a competitive differentiator.

We previously shared that we made commitments for future equipment needs in early 2021 in response to supply chain challenges. As I discussed previously, as part of these commitments, we made advanced payments of $29.3 million in the second quarter and we will be making additional advanced payments of approximately $16 million over the next three quarters to secure availability of this equipment and reduce ongoing carrying cost fees from these vendors.

We expect to take delivery of equipment covered by these commitments and deploy it over the remainder of 2022 and 2023. These payments will favorably impact our gross margin by reducing carrying costs and we do not incur any operating costs, including depreciation until we deploy this equipment. And despite our transition to our next-generation network architecture and acceleration of some investments due to supply chain constraints. As I previously discussed, with the benefits from our improved capacity planning processes, we now expect our cash capital expenditures in 2022 to decline to a range of 10% to 12% of revenue from our previously expected range of 12% to 14%.

I will now turn to discuss the outlook for the third quarter and full year 2022. I'd like to remind everyone again that the following statements are based on current expectations as of today and include forward-looking statements. Actual results may differ materially and we undertake no obligation to update these forward-looking statements in the future, except as required by law.

Our third quarter and full year 2022 outlook reflects our continued ability to deliver strong top line growth via improved customer acquisition and expansion within our enterprise customers, driven in part by new and enhanced products. Our revenue guidance is based on the visibility that we have today and given our usage-based business model, we expect to gain additional visibility to our annual guidance as the year progresses.

Historically, our first and second quarter revenues are generally flat with revenues increasing in the second half of the year. As a result, for the third quarter, we expect revenue in the range of $102 million to $105 million, representing 19% annual growth at the midpoint. We expect a non-GAAP operating loss of $21.5 million to $18.5 million and a non-GAAP loss per share of $0.18 to $0.15.

For the full year 2022, we are increasing our prior revenue guidance by $10 million to a range of $415 million to $425 million, representing 19% annual growth at the midpoint. We expect a non-GAAP operating loss of $78 million to $72 million and a non-GAAP net loss of $0.68 to $0.63 per share, reflecting the impact from lower gross margins and higher expenses I discussed previously. And to reiterate, we anticipate gross margins to improve in the second half of 2022.

Before we open the line for questions, we would like to thank you for your interest and your support in Fastly. Operator?

Question & Answers

Operator

[Operator Instructions] Your first question comes from the line of Frank Louthan with Raymond James. Your line is open.

Frank Louthan - Raymond James - Analyst

Great. Thank you. So just to be clear on the gross margins, if you – adding back the charge you took, it would have been more like 46.5%, is that correct? And then I missed what you said the back half would be and does this mean that the upgrade you are doing there is finished and the back half is sort of the full benefit of that or can we still expect gross margins to ramp going into '23? Thank you.

Ron Kisling - Chief Financial Officer

Yes, this is Ron. Couple of things. On gross margin, if you back out kind of the one-time activities or adjustments, as we said, we would have been about 50 basis points below where we sort of guided which was flat. So that would work out on a non-GAAP basis to be around 52% gross margins in the quarter, ignoring the one-time cost. As for the technology migration at our largest sites that is on track and is one of the drivers in the second half for improved gross margins as we are decommissioning the redundant sites that we put in place as we made this technology migration.

Frank Louthan - Raymond James - Analyst

Okay, great. Thank you. And can you walk us through the acquisition and just how you expect that to boost your other offerings in the space? Thanks.

Joshua Bixby - Chief Executive Officer

Sure. Hey, Frank, it's Joshua here. I think as we've said all along, as a platform for platform builders and as an organization that really supports developers, that journey doesn't just start when you are ready as an enterprise to adopt the technology. We have known for the lifetime of our business that that journey starts when you start experimenting. When you have a problem at 2 o'clock in the morning that you can't sleep and you are trying to solve, developers will wake up and they will try to solve problems. And so for us, the Glitch acquisition is incredibly important, because it continues that journey, actually drives that journey earlier into the developer lifecycle. Glitch is a tool that, as we said, is used by 1 million plus developers who are out there solving problems. And really what Compute@Edge is designed for us to solve problems for these people who build platforms and who are delivering platform. So we see it as being very important on the sales journey and not only that developer moment of inspiration but that carries through the entire enterprise cycle. So, we believe it's going to serve two main purposes, obviously, on the revenue side. But the other thing, when you get so many people experimenting with the tools, you actually start to find new use cases. And the innovation of the community starts to become part of that innovation cycle. And one of the things that you've seen from the business over the last few quarters and really highlighted this quarter is we are delivering – there is 14 important releases. Our – we are accelerating. We are getting faster. And I'm really proud of the team for doing that. And when we look at a community of millions of people experimenting, that only accelerates that. So I think it really helps in both areas of the business. It's very exciting.

Frank Louthan - Raymond James - Analyst

Alright. Great. Thank you very much.

Joshua Bixby - Chief Executive Officer

Your next question comes from the line of Fatima Boolani with Citigroup. Your line is open.

Unidentified Participant - - Analyst

Guys, this is Mark on for Fatima. Thanks for taking our questions. So it sounds like the strong expectations for the balance of the year. But can you give a sense of the puts and takes and maybe key drivers of guidance for the second half that you've actually seen that gives you confidence for the robust outlook on the top line for the back half, especially in the current environment. Thanks.

Joshua Bixby - Chief Executive Officer

Yes. It's Joshua here. I think that as we talked about, when you look at the enterprise number for the quarter, what we're seeing is large – our largest customers and those that are growing into that scale are more optimistic, are in the middle of these transformations, have large budgets. And so we are definitely seeing that side of the market, the market we really focus on continuing to grow. And I think when you look at the guidance for the year and the quarter and the next quarter, what you see is it's really off the back of those large customers. So we acknowledge that there is uncertainty across the entire customer base but we are definitely seeing within our larger, more established customers, we're seeing more their ability to plan farther out and the projects that they are working on are central to their digital transformation. What we've seen historically in all of these times of economic upheaval is that people do invest in digital transformation. They do invest in the channels that are working and they invest in ways to innovate. Right now, those channels are on the Internet and the innovation is directly related to where the edge cloud provides so much value. Performance matters, security matters and it matters even more in uncertain times. So I think it's very much related to the momentum in the largest customers. That's really why we've been able to raise guidance and we continue to see strength in the business. But by no means is it clear past sailing here? We absolutely see that there is uncertainty ahead of us.

Unidentified Participant - - Analyst

Okay. Great, thanks for that. And then maybe just moving on to the security business, thank you for the high-level details but maybe can we get an update on the momentum anything quantifiable would be much appreciated. Whether it's year-over-year sequential growth on your assets there? And then just given your 1% increase on the average enterprise customer spend, when can we maybe see some more apparent ramp there on the security business, maybe adoption from the customers? Thanks.

Joshua Bixby - Chief Executive Officer

Sure. So on the customer spend side, I think that that's a number that you have to look at over a longer period of time. There is puts and takes to that. I think overall, we're going to continue to see that go up as you say, as our customers start to and continue to adopt the security offering but also the compute offerings as well as other offerings. So what we continue to see and I mentioned that with a few Fortune 500 customers who have broadly adopted across the portfolio and increase their usage. That's a pattern that we're seeing and that will take some time to flow through. I think overall in the security business, Ron hit on the SigSci specific numbers. But if you go zoom out a little bit and look more broadly, what you'll see is that momentum is broad. We continue to innovate in that product line. We talked about the introduction of our Security Labs product. We talked about some of the private relay work that we're doing. I mean security is very much top of mind for our customers and we continue to see wide adoption. One of the encouraging elements for me is how often the next-generation WAF platform is being leveraged into our largest accounts across all of our business units. So from media through to high tech, through to technology, we are seeing that absolutely be adopted even in areas where initially, when we acquired Signal Sciences, we weren't sure how broad that adoption would be. So we have been pleasantly surprised and you can see that from the growth in that particular product offering.

Perfect. Thank you guys so much.

Your next question comes from the line of Rudy Kessinger with D.A. Davidson. Your line is open.

Rudy Kessinger - D.A. Davidson - Analyst

Great, guys. Thank you for taking my questions. Joined a little bit late, so I apologize if you addressed this in your prepared remarks. But when I look at the guide for the year, you're taking rev up $10 million you're taking the operating loss guide down by $10 million. What are the puts and takes? I know you're still saying gross margins will ramp in the second half. But if I look at that $10 million op loss reduction, how much of that is attributed to the Glitch, attributed to a lower gross margin outlook, increased opex spend on product or sales elsewhere. Just could you break it down for me?

Joshua Bixby - Chief Executive Officer

Sure. Ron, do you want to take that one?

Ron Kisling - Chief Financial Officer

Certainly. So I think a couple of drivers here. I think first, we did see Q2 operating expenses come in higher than we had planned at the beginning of the year. Some of that was driven by increased headcount across the organization. Glitch was a contributor to that increased headcount across the organization. We saw higher-than-expected salary increases, acceleration of T&E and increased investment in product and go-to-market activities in the first half as well as certain one-time expense items. So when you look at the impact on the first half, we now look or anticipate that operating expenses for the year as a whole will be higher than we planned at the beginning of the year. Although we still expect to see expenses down in the second half from first half as we put in place a lot of controls around our spending and hiring levels but largely due to that increase in spending from those drivers is why we took up the operating loss ranges for the year taking into account recognition of the increase in revenue. And from a gross margin perspective, while we still expect to see accretion in the second half, Q2 gross margins were lower than we had anticipated at the beginning of the quarter.

Rudy Kessinger - D.A. Davidson - Analyst

Got it. And then jumping to the gross margins, I mean, understanding there is 160 basis point impact in Q2, so really only down 50 points sequentially. But if I take a step back and compare the gross margins to, say, Q1 of 2020 pre-COVID were $57.6 million on a non-GAAP basis. And if I assume Signal Sciences is still about 80% gross margins, that would basically say that the rest of your business is running at about 46% gross margins, down about 12% from where you were pre-COVID. Understand you got some boost later in 2020 on gross margins. But I guess, just with the 12% kind of reduction in the rest of the business, what else is at play here besides the migration of some of your sites and the upgrades going on there and some pull forwards on capex? I have to imagine there is got to be some pricing pressure or mix shift in your business? What else is driving the gross margin compression?

Ron Kisling - Chief Financial Officer

Yes. I mean the big drivers and we talked about this through 2021 was an increase in our investments in our network infrastructure, both just in terms of investments in overall capacity as well as expansion internationally and particularly with new international sites when you initially deploy them, you're running at less than sort of full capacity. So those tend to be also a drag on gross margin. So a lot of that was driven by the investments we made in the network over the last, say, year or 18 months. Prospectively, as we look at the network, one, because of the investments we've made and two, as we continue to improve our forecasting we are able to align investments much more tightly with expected traffic. And so over time, we would expect capacity and traffic to come much more in line and drive improved gross margins as that sort of invest ahead of traffic is behind us.

Rudy Kessinger - D.A. Davidson - Analyst

Okay. Fair enough. Thanks for taking my questions.

Joshua Bixby - Chief Executive Officer

Thanks, Rudy.

Your next question comes from the line of Jim Fish with Piper Sandler. Your line is open.

Quinton Gabrielli - Piper Sandler - Analyst

Hi, guys. This is Quinton on for Jim Fish. Thanks for taking our questions. Maybe just first, enterprise revenue growth seemed to dip slightly compared to Q1 despite similar enterprise additions as last quarter. Are you seeing enterprise customers maybe slowed down on spend a little bit or take longer to decide on net new spending or was there something else impacting the mix of commercial versus enterprise this quarter, like some of your smaller enterprises maybe moving into the higher end of the commercial bucket?

Joshua Bixby - Chief Executive Officer

Ron, do you want to take that?

Ron Kisling - Chief Financial Officer

Sure. So I guess you had a couple of different dynamics around enterprise customers. I think when you look at it over kind of the medium-term continue to point to one, strong business with our enterprise customers. While on a trailing 12-month basis, it was down slightly at 1%, 88% of total revenues from 89%, we did see an increase in new enterprise customers this quarter of 14 compared to 12 in the last quarter and the average spend across our enterprise customers increased from $722,000 to $730,000. So we're seeing continued increase in terms of expansion within our enterprise customers. And seeing some growth in new enterprise customers is clearly a focus to take that growth in enterprise customers and look at how we accelerate that through the work that we're doing in marketing in terms of brand awareness and leads and the development of the sales organization to accelerate that.

Quinton Gabrielli - Piper Sandler - Analyst

Okay. That's helpful. And then maybe the last question from us is we've heard from recent reports how the gaming vertical specifically has continued to slow, especially as we move through the summer. To what extent is this slowdown along with slowing results from other verticals like streaming or e-commerce baked into the rate outlook provided? Are we assuming things continue to improve in the back half of the year or are current trends embedded into this guide? Thank you.

Joshua Bixby - Chief Executive Officer

Ron?

Ron Kisling - Chief Financial Officer

Yes. So as we look at guidance in the second half, I'd say we look at a couple of things. We look at the macro environment and certainly have taken into account what we believe the trends are across the key verticals that we play in as well as we look at what is the specific traffic that we expect to gain from our customers. We do a very detailed review of our customers in terms of what their plans are. And as we said, we've seen good expansion within those customers. And based on discussions with those customers, we've built out what we think are the traffic levels, our traffic shares are likely to be. And so it really is looking at our business, our traffic levels with our specific customers with recognition that the – it's a challenging environment. And I think the – as we sort of said on the call, we continue to see rate expansion. We continue to see new customers in a challenging environment given our relative market share that does give us some ability to sort of, if you will, mute some of the macro drivers.

Your next question comes from the line of Will Power with Baird. Your line is open.

Charlie Erlikh - Baird - Analyst

Hi, guys. This is Charlie Erlikh on for Baird. Thanks for taking the question. I just wanted to ask about maybe asking another way the revenue guidance and it pertains to the growth algorithm. Are you seeing any sort of shift in growth contribution from maybe new bookings or new customers added to the platform versus growth from existing customers or has it been pretty consistent because we've heard from others that maybe existing customers are growing faster than new customer growth relative to past periods?

Ron Kisling - Chief Financial Officer

I think where – what we saw in the second quarter was really driven by growth within existing customers. And it was a combination of traffic as well as gaining new types of traffic and new types of business with those customers. So the expansion is really around book delivery and the types of services were within those customers. We continue to see new customers. Enterprise customers did increase in the quarter. We added to our total customer base. But our core dynamic, if you look at our business is typically customers that we add in the current year contributed 5% to maybe 7% of our revenue because our customers do typically ramp and contribute and expand over time. And I would say that pattern that we've seen in the past is intact.

Charlie Erlikh - Baird - Analyst

Okay. That makes sense. Also, I just wanted to ask if there was any changes in trends between like April versus May versus June and now July is behind us. Is there any change in the trend between those months or was it pretty consistent throughout?

Ron Kisling - Chief Financial Officer

I think what we saw and this kind of mirrors kind of what you see from our revenue traffic. We started to see traffic trend up as we got toward the end of the quarter. And I think that's fairly consistent with our overall pattern. Q1 and Q2 tend to be relatively flat. We start to see increased revenues in Q3 and further acceleration in Q4. And so traffic ramped as you moved through the quarter with higher traffic in June going into the summer months where we see the higher levels of traffic.

Charlie Erlikh - Baird - Analyst

Got it. Alright. Thanks.

Joshua Bixby - Chief Executive Officer

Thanks, Charlie.

Your next question comes from the line of Philip Rigby with RBC Capital Markets. Your line is open.

Philip Rigby - RBC Capital Markets - Analyst

Hi, great. Thanks for taking the question. I want to start with a follow-up on guidance. If I look at your guidance, it seems to imply a bit of a deceleration in 4Q. Is that just pertaining to the uncertainty that you talked about or are there other factors or assumptions in play there?

Ron Kisling - Chief Financial Officer

Yes, I'd say it's primarily tied to kind of the uncertainty. I mean we've taken a strong view that we're a usage-based business that creates some volatility. And so as we build our guidance, we take that into account. And certainly, as to the earlier question, we take into account kind of the macro trends that we're seeing as well as the trends we're seeing kind of on a micro basis within our own customer base.

Philip Rigby - RBC Capital Markets - Analyst

Got it. Thanks. And then you mentioned increased salaries for employees but I'm curious, if I look at where the stock is performing relative to some of the RSU issuances. I would be curious to hear your thoughts on stock-based comp for existing employees. Any changes in philosophy or strategies you're thinking of taking there? Yes, any insight would be great. Thank you.

Ron Kisling - Chief Financial Officer

Yes. So yes, so no real change in philosophy. I think retaining employees has been really critical, particularly in this competitive environment. And I think we have used a combination of things. We talked a little bit about salary increases in the first half being a little higher than we anticipated. And we have used a combination of equity and salary to be competitive. I anticipate, just as you look at kind of the changes in the macro economy and the hiring environment, I expect the competitiveness in the hiring environment to become less competitive rather than more competitive as we kind of see the rest of the year based on where you are seeing kind of the economy and overall hiring statistics which will certainly impact the level of competitiveness in the hiring environment.

Your next question comes from the line of Jeff Van Rhee with Craig-Hallum Capital. Your line is open.

Unidentified Participant - - Analyst

Hi. This is Daniel on for Jeff Van Rhee. Just a quick question on developers and the traction there and Glitch. Just if you could give us any additional color, walk us through, you said 100,000 incremental developers on the platform. Just any sort of sense of the scale of that relative to developers currently using Fastly or just any other metrics or color you have around developer momentum? Thanks.

Joshua Bixby - Chief Executive Officer

Yes, absolutely. When we acquired the platform, it was around 1.8 million, so you add 100,000 in the quarter, you get a sense for sort of how that's scaling. One of the things that Glitch has done exceptionally well has been very intelligent about how it scales its community. So, instead of sort of opening the doors and encouraging everyone to come, they have been very thoughtful. This is a team that comes out of building some of the best developer-led products that the world has ever seen. So, they understand how that works. And one of the things that they have learned is that in order to build an exceptional developer community, you need to have exceptional features and you need to be listening to your community early and iterating. So, they followed that model. So, what we are seeing is a very consistent growth path. That's what we saw very consistently over their history and that's what we will continue to see. Compared to Fastly's history, these numbers are huge. I mean if you look at what we were doing before Glitch, it was a fraction of this and that's what was so exciting about this deal for us is it just absolutely Turbocharge is our ability to get developers. One of the things that was also very important was that 60% are in that range of their developers really were enterprise developers. And so that also is a very important metric for us in terms of thinking about where the targets are because we want all developers to use Fastly and we particularly want those that work in enterprises to use us.

Your next question comes from the line of Tom Blakey with KeyBanc. Your line is open.

Tom Blakey - KeyBanc - Analyst

Hey guys. Thanks for taking the question. My question – I have a couple, I have a follow-up for Ron here. But my first question was on Compute@Edge and developers as well. We are at a couple of million or almost a couple of million developers. Now how is Fastly thinking about incentivizing these developers to work on Compute@Edge. I don't – I am sure not all of them are well versed in that, just incentives there. And also maybe as an illustration, Joshua, like maybe what is that Japanese win? Like what are they working on? And what is kind of the economic opportunity alongside the app development platform? That's my first question.

Joshua Bixby - Chief Executive Officer

Sure, that's a great question. I think you are absolutely right. The edge is an area that is novel and new for a lot of developers. So, it really starts with bringing – making sure those tools are available and giving people the financial leeway in order to experiment. So, we talked about a program, a very successful program that we launched in Q4 and carried through to Q1. And we are still looking at ways where we can take this idea of taking the financial risk out of it in order for people to experiment. And the reason that's beneficial to take the financial risk out is because – and it comes back to that that question about use cases – is because it brings so much value. So, we see customers dramatically reducing their central cloud bills. We see customers dramatically improving the performance of their applications. We see customers – like some of the examples we have stated earlier, where their sites are becoming significantly more personalized without playing off this consistent theme of, I could make it personalized but it's going to make it slow. What Compute@Edge brings is the ability to not be making that trade-off. And those are the kinds of things that we are seeing but it absolutely starts with – it starts with this idea of experimentation and taking the risk out of it. And so that's really what we see and we see a lot of use cases which speak to bringing together the unique capabilities of Fastly and which really come back to this idea of performance and scale and security. That's what's central to all of this.

Tom Blakey - KeyBanc - Analyst

Good answer. And have incentivized, it just sounds like you are. And then for Ron on the gross margin, sorry, Ron. But the – I think on the last call, we talked about mid-50s for the year in '22, now kind of low to mid. There is a lot of one-timers in here. That's kind of a question, I suppose. And engaging with the percentage of maybe one-timers in the second half going into the second half of '22, what are you building Fastly for structurally in terms of what gross margins can be sustainable long-term, '23 and beyond? Do you think that would be helpful for everyone?

Ron Kisling - Chief Financial Officer

Yes. I think that's a good question. And I think what I would look to and I think was referenced earlier, if you kind of look back to kind of the margins we saw sort of in '21, I think there is an opportunity to get back to those margins as we get some of these one-time things behind us with the efforts we put in place to better align our capacity investments with traffic on a go-forward basis. And then I think from there, then you can see additional accretion over time as we add – as security grows as a share of that, as we add more Compute@Edge. But I think as what I would say, maybe a medium-term guideline would be to see kind of where we were in '21 and that's attainable just by getting beyond some of this technology transition that we talked about last quarter and managing capacity in line with traffic and bringing those two close to our line.

Tom Blakey - KeyBanc - Analyst

That's great answer. Thanks for the clarity Ron. Just as a clarification. Last question for me. Is that 10% to 12% capex comment, impressive. Does that include – that can't include the advanced payments in PP&E in '22. Does it and…?

Ron Kisling - Chief Financial Officer

Correct. It does not include the advanced payments. When we take delivery of that and actually deploy it, we will include that in our cash capex. So, that's when we actually take title of the equipment when we start depreciating it. So, as we take deliveries out of that, that will be reflected in our cash capex. We will take some deliveries from some of those commitments in the second half and so the deliveries against those purchase commitments are reflected in that outlook of 10% to 12% cash capex.

Tom Blakey - KeyBanc - Analyst

That's interesting. And maybe it's part of the upgrades that you are making to the network. Could you state now that you expect that range to kind of be consistent for at least the foreseeable future, like in the out years?

Ron Kisling - Chief Financial Officer

I mean I think, generally, I think as you look, absent any sort of other major sort of changes to the product, generally, I see that as the level. I mean ultimately, I think we are getting more efficient in terms of our capital deployment across the network and that would be kind of a good sort of medium-term guide.

Tom Blakey - KeyBanc - Analyst

Very good. Thanks guys.

Ron Kisling - Chief Financial Officer
