Thank you, Samantha. Good afternoon, everyone, and thank you for joining us today for Connection's Q2 2022 conference call. I'll begin this afternoon with an overview of our second quarter results, highlights of our performance, and then share our updated thoughts on our business and the remainder of the year. Tom will walk us through a more detailed look at our financials. We had an outstanding second quarter. Our team continued to execute well against our strategic objectives across each of our business segments with all-time record quarterly results for revenue, gross profit, and net income. We experienced double-digit growth across all three of our business segments. These exceptional results demonstrate the continued execution of our business strategy to connect our customers with technology that enhances growth, elevates productivity, and empowers innovation. The technology and solutions that we provide are highly valued by our customers.
As we look forward, we believe that our products and services will become even more essential in helping our customers to achieve their business objectives with technology. On a consolidated basis, Q2 revenue grew by 17.7% compared to last year's second quarter. The Business Solutions segment grew 22.9%, while the Enterprise segment grew 13.6%, and the Public Sector grew 16.5%. In addition, we continue to see our customers' business environments evolve as they adapt to supporting both remote and in-office work. Customers are focusing on the need to improve security, increase productivity, manage costs, and modernize their businesses. Our vertical markets teams delivered strong double-digit revenue growth in our finance, manufacturing, and retail markets, with growth rates of 40%, 16%, and 10% respectively.
Our healthcare vertical, which is our largest vertical, grew revenue 5% year-over-year, following a growth rate of 30% in Q2 of 2021. During the quarter, we saw pockets of improvement in the supply chain, which resulted in a slight decrease in our backlog sequentially, although still significantly higher than a year ago. The overall supply chain remained challenged, and we expect it to continue through at least the balance of the year. Our team has continued to leverage our partner relationships, scale, technology integration and distribution center, and logistical capabilities, as well as our strong balance sheet to navigate the ongoing supply constraints on behalf of our customers. Now let's discuss our Q2 performance in a little greater detail. As I stated earlier, second quarter revenue was up 17.7% to $828.5 million from 2021.
While gross profit was up 17.7% to $136.9 million, both all-time records. Gross margins were 16.5%, up 4 basis points from Q2 2021. Operating income in Q2 was $34.8 million, an increase of 46.3% or 4.2% of net sales, compared to $23.8 million or 3.4% of net sales in the prior year quarter. In Q2 2022. Our diluted earnings per share was $0.96, an increase of 46.5% from $0.66 in Q2 2021. We ended Q2 with $94.9 million of cash and cash equivalents. We'll now look a little deeper into segment performance.
In our business solutions segment, our Q2 net sales hit an all-time record of $328.4 million, an increase of 22.9% compared to $267.3 million a year ago. Gross profit in the business solutions segment was $65.5 million, an increase of 27.7% from a year ago. Gross margin increased 75 basis points to 19.9% in the quarter compared to the prior year, primarily due to changes in product mix. We saw an increase in demand for data center products with strong growth in the storage and server categories, cloud, security, and software also experienced good growth. In addition, demand for workplace transformation products remained strong.
Our customers continue to invest in technology to gain a competitive advantage, and they turn to us to calm the confusion and guide them through their transformations. In our public sector solutions business, Q2 net sales were $151.2 million, an increase of 16.5% compared to $129.7 million a year ago. Sales to state and local government and educational institutions were $131.2 million, an increase of 24.8% compared to the prior year, partially offset by a decrease in sales to the federal government year over year. The Emergency Connectivity Fund continues to be a driver of demand in the K-12 market, and that will extend through December of 2023. Furthermore, the infrastructure stimulus bill allocates funds for technology purchases that should continue to create opportunities for our SLED business.
Gross profit for the public sector was $20.8 million, an increase of 15.5% compared to Q2 of 2021. Gross margin decreased by 12 basis points to 13.8%, primarily due to changes in both product and customer mix. In our enterprise solutions segment, Q2 net sales were $348.9 million, an increase of 13.6% compared to $307.2 million a year ago. Gross profit for the enterprise segment was $50.6 million, an increase of 7.6% compared to the prior year quarter. Gross margin for the quarter decreased to 14.5%. While the gross margin this quarter is in line with historical rates, they are 80 basis points lower than the prior year.
As you may recall, in Q2 2021, the enterprise segment benefited from multiple data center rollouts that did not repeat in the current quarter. I'll now turn the call over to Tom to discuss additional financial highlights from our income statement, balance sheet, and cash flow statement. Tom?
Thanks, Tim. SG&A decreased 82 basis points to 12.3% of net sales in this quarter due to improved efficiencies on higher revenue. On a dollar basis, SG&A increased $9.6 million compared to the prior year quarter. The increase in SG&A was primarily due to an increase in personnel cost associated with an investment in incremental headcount focused on building stronger marketing and technical organizations, and an increase in variable compensation due to higher levels of gross profit. Q2 operating income was $34.8 million, up 46.3% this quarter from $23.8 million a year ago. Our effective tax rate was 27%, down from 27.3% in the same period a year ago. Net income for the quarter was $25.4 million, an increase of 46.9% from $17.3 million a year ago.
Diluted earnings per share was $0.96, an increase of 46.5% from the prior year period. Our trailing twelve-month adjusted earnings before income taxes, depreciation, and amortization, or adjusted EBITDA, was $140.5 million compared to $96.7 million a year ago, an increase of 45%. Cash flow used in operations for the first six months of 2022 was $8.4 million versus cash flow generated from operations of $31.8 million for the same period a year ago. The decrease in cash flow from operations reflects higher levels of business activity, and consequently, both accounts receivable and inventory increased in the first six months of the year. In the quarter, we generated $29.9 million in operating cash flow as our DSO improved by three days and our inventory balance decreased by $11.4 million.
Our net cash used in investing activities of $4.6 million in the first six months of 2022 was primarily the result of equipment purchases and IT initiatives. We also have $12.7 million for stock repurchases under our existing stock purchase program. I will now turn the call back over to Tim to discuss current market trends.
Thanks, Tom. I want to take a few minutes to review some of the highlights in our business. Our growth in Q2, again, is largely attributable to the customized IT solutions that we deliver on behalf of our customers as they continue to work through their digital transformation and efforts to gain competitive advantage with technology. Our customers look to Connection to deliver these innovative solutions. Towards that end, we continued to leverage our managed services capability, and we're excited about the performance and the volume of activity that we experienced during the second quarter at our technology integration and distribution center. Our customers trust us with their mission-critical solution deployments, and in fact, we achieved a record volume of custom configurations in the quarter.
Our years of experience with supply chain optimization and our ability to deliver custom solutions continue to be important components of our growth and a competitive differentiator for us. Our growth was also attributed to our expertise in delivering custom solutions to our vertical markets. For example, in the retail vertical, we grew revenue 10% year over year as a result of retailers investing in employee productivity, the customer experience, and inventory management systems. Revenue for the manufacturing vertical grew 16% year over year as manufacturers focused on productivity, cost reduction, and improved quality through the use of innovative technologies as a means to meet business objectives and gain long-term competitive advantages. These changes are driving investments in networking, security, hybrid data center, and end user devices.
Looking forward to the remainder of 2022, customers will wanna manage costs while leveraging technology for greater efficiency and as an enabler for competitive advantage. We expect our customers to continue to focus on data center, security, and cloud transformation. As discussed, we believe that supply chain constraints will continue to plague the industry. Although the worst is behind us, headwinds will continue into 2023. We expect our quarter-on-quarter growth rates to be lower in the second half than the first half. These expectations are a result of a tougher comparison from the prior year and our customer-serving global markets becoming more deliberate in their technology investments. We believe we can still deliver organic growth rates that are 200 basis points-300 basis points above the IT industry and continue to take market share.
We remain focused on helping our customers achieve their productivity and efficiency goals while keeping them secure and connected in this evolving hybrid work environment. I'd like to take a moment to thank our valued employees for their continued effort and extraordinary dedication during this rapidly changing environment. We will now entertain your questions. Operator?
Thank you. At this time, we'll conduct the question and answer session. Please wait for your name to be announced. We will stand by while we compile the Q&A roster. Our first question comes from Anthony Lebiedzinski.
Yes.
Right.
Go ahead, Anthony.
No worries. Good afternoon. Thank you for taking the questions. I guess, you know, first, you know, Tim, you talked about the customers now being more deliberate and certainly recognizing that you do face tougher comparisons now in the back half of the year. You know, are you seeing that kind of across the board in each of your three main segments, or are there any of the segments that you're seeing perhaps, you know, a bit more modest growth? Just how should we think about that?
Well, thanks, Anthony. Clearly in the second half, if you look at the macroeconomic backdrop, the customers that we think are gonna be most affected are those customers that are large and perhaps have a global presence. Some of our large customers are slowing down for the second half. We're pretty confident overall. We've got an extraordinary backlog heading into the back half of the year. Overall, we're bullish on the business. I would say SMB has been resilient and remains very strong. We're going into the busy season for public sector. As you know, September is a busy month for federal. I'd say enterprise is probably the most under pressure, but that I think is consistent with what you're seeing out there in the competitive landscape. I think we're in great company.
You saw our competition announce over the last couple of days, and they too had extraordinary results.
That's correct. As far as your backlog, I mean, you mentioned that it was down sequentially, but still up year-over-year. Can you give us a little bit more color as far as like the components of the backlog? Has that changed much? If you just talk about that'd be great.
Yeah. I think, Anthony, the part that eased up a little bit was certainly in the device area. When we look at, you know, the server storage, networking type things, that continues to be pretty challenged. I'd say, you know, the drop in our backlog wasn't gigantic, but it was, I'd say moderate, you know?
Okay. Got it. Okay. Thanks for that color. You know, a couple more questions here. You know, inventory was down sequentially. How should we think about where you think you'll end up the year with inventory?
As you know, Anthony, you know, last quarter I think was an all-time high. You know, we worked really hard to bring it down. As things start to ease up a little bit in the supply chain, we can ship, you know, more and more of what we have in inventory. I think as we go through the year, I think it will kinda gently moderate back towards, you know, kind of our normal levels, which are in the, you know, call it 130 range-150 range. I don't know if we'll get all the way there. I don't know if we'll get all the way there by the end of the year, but certainly that's where we're headed directionally.
Got it. Okay. That would be sort of nice progress from here. Then, lastly, in light of everything that's going on in the world, you know, as far as, you know, just, you know, macro concerns that are out there, have you made any changes to your own hiring plans?
Actually, we've been full steam ahead there. We've seen a nice recovery in our ability to hire. You know, there had been a little bit of a lull when things were under pressure a couple of quarters back. We're now getting back to a more normal cycle. We're starting sales classes in a much more usual and ordinary way, and we have no plans to let up on that. We are also investing in technical engineering and technical sales arenas.
Yeah. I would also add to that, Anthony. You know, in the last half of last year, you know, we did make some adjustments, you know, to our compensation programs and our benefit programs, and we have been able to reduce the turnover a fair amount.
Got it. Okay. Thank you very much and best of luck.
Thank you.
Thanks, Anthony.
Thank you, Anthony. Our next question comes from the line of Catherine Huntley of Raymond James. Hannah, your line is open.
Hey, guys.
Hey, Catherine.
Hey, Catherine.
Could you guys just talk a little bit about the managed service capabilities? Was that an incremental uptick quarter over quarter? Would you maybe attribute this to the stressed hiring environment that the customers are facing, so maybe they're turning to you guys and using your services instead?
Yeah, Catherine. That's a great observation. We see the demand picking up in a few areas. As I mentioned, it was a record quarter for us for advanced configuration. Certainly where employees are working remotely or in a hybrid fashion, more than ever before, our customers are asking us to completely outfit them to manage that image, that asset, and in some cases that install and de-install. The managed service components would be wrapping a help desk and emergency services around that. All the support that goes around that hybrid worker has been a driver of demand. We're also seeing an uptick for companies who want us to outfit either their office or their location, and we now are able to do that in a very deliberate and precise way in our technology integration and distribution center.
In many cases, we can deliver an office or a location with one shipment, everything preloaded, pre-configured and ready to go. That has really been the uptick in our volume.
Okay, awesome. Thank you so much for all of that color. Could you maybe just give us a sense for how far customers are booking orders out? I know that it may have been elevated during COVID, but has that started to come back down, or are you still seeing customers book orders really far out to get ahead of inventory? Thank you.
It does depend, I think, on the category. Some of our security and Net/Com products are booking way out in advance because those have the longest lead times between some other very long lead times and some data center products, and that is probably manufacturer-specific, but certainly very long lead times. The lead times around our device, our endpoint device business are getting much better as we're seeing a little easing of pressure there. It's mostly the infrastructure data center and security products that still have the extended lead times.
Yeah. I would tell you know, it's a supply chain, you know, like you heard me talk a little bit about the inventory. Hopefully, as the supply chain issues, you know, start to work their way through and lessen in severity, you know, we're gonna be able to convince our customers to get back to holding a month worth of inventory or a few weeks of inventory rather than, you know, multiple months. I think we'll try to pull all this stuff together and, you know, slowly work down the working capital we have invested in the company.
Awesome. Best of luck and great quarter.
Thank you.
Thanks, Catherine.
Thank you, Catherine Huntley. I would now like to send it back to the company for closing remarks.
Well, thank you, Cal. I wanna thank all of our customers, vendors, partners, our shareholders for their continued support. Once again, our dedicated coworkers for their efforts and extraordinary dedication through this time. Thanks. Have a great evening.
Thank you, gentlemen. Thank you for participating in today's conference. This does conclude the program, and you may now disconnect. Thank you.
