I will now turn the call over to Ekso Bionics Chairman and CEO, Steven Sherman.
Thank you, David and thank you to everyone for joining us today. We achieved strong revenue growth in the second quarter, reflecting the continued execution by our team. We are successfully raising awareness of the benefits that our innovative Ekso NR devices are bringing to patients. This is resulting in strong demand with inpatient rehabilitation facilities and network operators. Now, with the recent clearance by the U.S. Food and Drug Administration, giving us the ability to market Ekso NR for use with MS patients, we are poised to help a significantly larger patient population. Our Ekso Works business continues to build momentum with large key customers as they more clearly understand the overhead productivity and safety benefits that our Ekso EVO devices deliver.
W e expect this segment to be a significant contributor to our growth in the future. Financially, we are in a solid cash position. Our dedicated team of professionals are constantly improving efficiencies. Our commercial team is deepening customer relationships. Management team is motivated by our core responsibility, which is to maximize shareholder value. Now I will turn the call over to our President and Chief Operating Officer, Scott Davis.
Thank you, Steven. Ekso Bionics generated strong revenue growth in the second quarter, reflecting the continued positive traction we are making with network operators. This momentum resulted in year-over-year revenue growth of 57%, led by our EksoHealth segment, which delivered $3.2 million of revenue. We achieved a couple of major company milestones this quarter. First, we delivered on the largest order in Ekso's history. This multi-unit order was comprised entirely of capital purchases. We're proud of this accomplishment and believe that it highlights our commercial team's effort to engage with large network operators who are now choosing to make EksoNR their standard of care in neurological rehabilitation.
Second, as Steven just mentioned, the FDA's 510(k) clearance to market Ekso NR for use with MS patients not only gives more patients in need the opportunity to rehab using our leading exoskeleton devices but it also meaningfully expands our total addressable market. I'll touch more on this in a moment. Turning back to our performance for the quarter. We booked 17 Ekso NR units, a majority of which were capital purchases. Demand continues to improve as capital budgets previously restricted by COVID are opening up. Our cumulative conversion and renewal rate remains strong at 82%, with approximately one point nine million dollars of contracted unrecognized revenue under our subscription model. Additionally, we have witnessed an encouraging trend whereby our customers are increasingly committing to multi-year subscription agreements, which indicates their confidence in the value proposition of the Ekso NR.
For example, Avera McKennan, a network operator in Sioux Falls, South Dakota and our first customer in the state, recently secured a multi-year EksoNR subscription. In the international market, we're pleased to have recorded a strong booking quarter, particularly in Europe. The strength in Europe underscores our investment in lucrative indirect partnerships in that region. In APAC, we generated a solid number of bookings as well, adding to our optimism. We continue to see these regions as important growth drivers in the years to come. Now for a discussion on the FDA clearance of the EksoNR for multiple sclerosis indication and what it means for MS patients and our business. EksoNR is the first exoskeleton device to receive FDA clearance for rehabilitation use in patients with MS.
With this, we are excited to bring our device to a broad group of patients in need. According to the National MS Society, there are nearly one million people in the U.S. living with MS and more than 2.8 million globally. Every five minutes, someone is diagnosed with MS. These patients will have access to a wearable robotic device, potentially improving their mobility and supporting them in their rehabilitation. I'd like to share a story of how a patient with MS benefited from an EksoNR from the Kessler Foundation, one of the facilities that provided data to help us receive this clearance. Pilar Santillana was diagnosed with MS in 2006 and as the progression of the disease worsened, it impacted her ability to walk.
Pilar joined a novel pilot study led by Dr. Guang Yue at the Kessler Foundation, evaluating robotic exoskeleton training in MS using EksoNR. As part of the eight-week study, Pilar learned how to balance, stand up straight and improve her posture and gait mechanics. At the end of the 8-week training session, Pilar said, "What I had done with the exoskeleton, three months of physical therapy could never do." Dr. Guang Yue was quoted as saying, "Initial findings suggest that robotic exoskeleton training improves mobility and cognition and may play an important role in the future rehabilitative care for people with MS." We're proud of Pilar's progress and hope to see many more success stories like hers. Turning to an update on the progress with our industrial segment, EksoWorks.
We're making inroads with several large customers with sizable employee headcounts who can benefit from significant workplace productivity and safety features that EVO provides. We continue to see demand primarily emerging in the automotive, aerospace and solar energy verticals. Our current strategy is geared toward developing larger customers, which can result in a longer sales cycle like it did this quarter. For the second quarter, EksoWorks delivered approximately $237 thousand of revenue. As construction, general manufacturing and green energy ramps up across the country, we remain committed to educating and expanding customer access of EVO to a wider number of industrial verticals. As we've previously mentioned, our target industrial verticals represent a vast addressable market opportunity of approximately $5 billion.
Moving forward, our commercial team is focused on building customer awareness and engagement to ensure the success and safety of our customers' workforce. I'd like to take a moment to comment on the challenges associated with the global supply chain and our plans to mitigate its effect on our business. Like so many other businesses, we're not immune to the tight supply market. Our devices are comprised of more than 600 unique components. As discussed earlier, we're pleased with the healthy demand environment. However, with that comes a greater need for supplies, resulting in manufacturing pressures. To ensure that we can fulfill current and future orders in a timely manner, we made the decision to order parts well in advance of when we would ordinarily do so.
This has led to an increase in our use of cash and when combined with inflationary pressures, can impact our gross margins. Nevertheless, we are well-financed and well-prepared to navigate through the current market environment. We have an experienced team of professionals managing our business, allowing us to prudently manage our expenses and limit our cash burn. Finally, I'd like to briefly highlight a corporate update. We're currently in the process of moving our headquarters across the San Francisco Bay to a new facility in San Rafael in Marin County. Our new headquarters aligns with our current management, administrative and manufacturing needs. We expect to complete this move during the third quarter. Looking ahead to the second half of the year, our outlook remains that of cautious optimism.
Driven by the strength of our commercial team, we are increasingly encouraged by the progress of our growing customer engagement levels and international opportunities. Our innovative wearable exoskeletons are among the most studied exoskeleton devices in the industry, with more than 180 unique publications demonstrating significantly improved patient outcomes. Now, with the EksoNR receiving FDA clearance for MS, we are excited to bring our game-changing solutions to a greater number of patients who are in need. Before turning the call over to Jerome Wong, who will discuss our second quarter 2022 financial results, I'd like to recognize his recent appointment as our interim CFO. Jerome has served as the company's controller since May of 2017 and brings more than 20 years of experience in finance, accounting and strategy to this role.
His knowledge of our finance and accounting controls enables a seamless transition. Now, I'd like to turn the call over to Jerome.
Thank you for those kind words, Scott. Now onto a summary of our second quarter 2022 financial results. Ekso generated second quarter 2022 revenue of $3.5 million compared to $2.2 million for the second quarter of 2021, an increase of 57%. This increase in revenue was primarily driven by an increase in the volume of EksoNR device sales. Our gross profit for the second quarter was $1.6 million, representing a gross margin of approximately 47% compared to a gross margin of 58% for the same period in 2021. The overall decrease in gross margin was primarily due to the increase in EksoHealth service and inventory costs due to the continued global supply shortage, partially offset by a favorable change in product mix.
As we noted on previous calls, gross margin tends to fluctuate from quarter to quarter based on channel and product mix, as was the case this quarter. Operating expense for the second quarter of 2022 were $4.9 million compared to $4.6 million for the second quarter of 2021. During the second quarter of 2022, the company incurred increased expenses related to increased sales and marketing activities and higher research and development expenses due to sustaining engineering activity for the EksoNR and the development of next generation products. Net operating loss in the second quarter of 2022 was $3.2 million, compared with a net operating loss of $3.3 million in the prior year period.
Gain on warrant liabilities for the quarter ended 30 June 2022 associated with the revaluation of warrants issued in 2019, 2020 and 2021 was $1 million, compared with a gain of $0.9 million due to the revaluation of warrants issued in 2019, 2020 and 2021 for the same period in 2021. Turning to our 2022 first half results. Revenue increased $1.9 million or 46% to $6 million for the six months ended 30 June 2022, compared to $4.1 million in the same period of 2021. The increase in revenue was primarily driven by an increase in the volume of EksoNR device sales and the recognition of previously deferred prepaid royalties associated with a license and distribution agreement that expired.
Gross profit for the six months ended 30 June 2022 was approximately $2.9 million, representing a gross margin of approximately 47%, compared to a gross profit of $2.5 million for the same period in 2021, representing a gross margin of 61%. Operating expenses for the six months of 2022 were $10.3 million compared to $9 million for the same period in 2021. During the first half of 2022, the company incurred increased general and administrative expenses, primarily due to non-cash stock-based compensation and severance expense and higher research and development expenses due to an increase in product development activities. Net operating loss in the first half of 2022 was $7.5 million, compared with $6.5 million for the comparable period in 2021.
Gain on warrant liabilities for each of the first half of 2022 and 2021 was $0.9 million in each case from the revaluation of warrants issued in 2019, 2020 and 2021. Cash used in operating activities in the first half of 2022 was $8.5 million. As of 30 June 2022, the company had a strong cash balance of $31.9 million. Please see our 10-Q filed earlier today for further details regarding the quarter. Operator, you may now open the line for questions.

Our first question today is coming from RK from H.C. Wainwright. Your line is now live.
Thank you. Good afternoon, Scott and Steven and Jerome.
RK.
Hi. A couple of quick questions from me. You know, it's great to see that, you know, most of your sales came from the multi-unit orders. I mean, sorry. In terms of that, of the 17 units that got sold under this, can you give us a little bit more color on that? And also, you know, when you start doing trials with some of these potential clients, you know, do you know, gravitate more towards the multi-unit orders clients or, you know, you're going to be agnostic at this point?
Okay. Thank you for your question. Really two-part question. You know, talking about the 17 bookings that were made in the quarter. Of those bookings, we had a mix of both capital as well as subscription. I'm sorry, five of those being subscription and the balance being capital of that, you know, of the orders that we had. In terms of selling into IDNs relative to some of the, you know, smaller clinics that are out there, our sales team really has a focus with focused sales professionals that are targeting the larger IDNs and then also the slightly larger regional IDNs. We still have a sales focus on some of the smaller clinics as well. We have a portion of our sales team that continues to work with those network providers, with those IRFs.
If you look at the bulk of what we're really working on is really the larger customers and that is absolutely paying off as we've seen a significant increase, you know, over the years in sales to those larger IDNs. From 2019 and 2020, somewhere around 30% of sales and now upward of 70% in 2021 and 2022.
Perfect. Then, you also said in ex-US, especially in APAC, you had solid numbers. I would like to understand what that solid number means.
Okay. You know, in APAC, we had two bookings that were in Hong Kong. In Europe, we had 8 total bookings that were capital and driven through distribution in that market this quarter. All of them were actually through distribution in Europe.
Perfect. In terms of multiple-year subscription, you said that there is increasingly more interest in having multiyear subscriptions. Obviously it's good news on one end and on the other side, you know, how are these set up in the sense, you know, what is a multiyear? Is it more than two years? And if so, is there a clause as to conversion to a capital purchase at the end of, you know, the second or the third year, whatever is the term?
Sure. Great question. In general, when we talk about a multiyear subscription, we're selling 24-month subscription within our program. Typically, if it's reaching beyond that, we would consider capital procurement options, whether through a direct capital purchase or through a capital lease for the customer. 24 months has a, the part of the reason for that is as our clinics are rolling out new programs with Ekso, we want to give them sufficient time to really realize the benefits of implementing a neuro rehab program using the EksoNR. What we found is, you know, within a 12-month period, certainly they can experience those benefits but, you know, it really takes, you know, 18 months to really start to, you know, enjoy the benefits of that.
As a result, we anticipate that driving, you know, customers who will resubscribe at the end of that term because they've had successful programs.
Very good. Going to the new indication, MS. You know, you gave us the number of patients in terms of annual incidents. What is the real market opportunity for you in terms of rehab? And when your commercial folks go out there, is that a different call point or is the same rehabilitation unit handles both, you know, stroke and other patients along with MS or are they two different places that they need to go to?
Great question. We are very excited over our MS indication, largely because we can help an entirely new segment of patients with these great outcomes. One of the things that's quite different about an MS patient relative to some of the other neuro patients that we have with, you know, SCI or acquired brain injury, is that, you know, these patients will have a continuation of sort of degradation over, you know, the period of having their, you know, this disease. We like to say that, you know, with Ekso, patients walk out of an Ekso. With MS, this is something that can be used as a treatment to prolong and preserve their health and fight against this illness and give them all the health benefits from that.
To that end, yes, there's a large addressable market that exists for this. There is crossover. You know, for some patients who have you know, acute spells of this, certainly inpatient rehabilitation is an area that they would use it. This expands our reach into outpatient rehabilitation. We have crossover into outpatient right now but this is effectively bringing us down the continuum of care into outpatient as well.
Very good. And then my last question here before other folks can jump in. On the supply chain, I know you talked about this during the last quarter call and it looks like you have a handle on this right now. What is the status, you know, in terms of managing the supply chain? And I also see that your inventories number has gone up quite a bit, more like a 50% than last quarter. I mean, than December, rather. Does that mean over time, you know, your gross margins should improve because some of these inventories that are currently on books will get reduced?
That's correct. As we've talked about for the last couple of quarters, supply chain challenges have been just something that's been plaguing not only us but everybody. Anyone who's dealing with circuit boards or even mechanical parts, it's been challenging. We did place orders much more aggressively than we ordinarily would have to ensure that we maintain the supplies necessary to meet our growing demand. As you can see, the result of that is that our inventory is up and yes, of course, it also is having an impact on margins. What we expect over time, as we've gotten ahead of this and assuming at least consistency and no further degradation in the supply chain environment, we expect that over time that will begin to normalize.
You know, we are obviously looking for ways to, you know, improve those costs as we move through the crisis and get us back to a margin position that is more along what we expect.
Thank you. Thanks for taking all my questions.
Thank you, RK.
Thanks. Our next question is coming from Kyle Bauser from Lake Street Capital Markets. Your line is now live.
Great. Thanks, Steven, Scott and Jerome for all the updates here and congrats on a really strong quarter. Maybe I'll follow up on the MS opportunity and sorry if I missed this, Scott but can you talk just a little bit more about maybe the broader opportunity as you kind of outlined it in terms of incidence but also prevalence? I mean, is there an opportunity to treat the prevalence pool here? And then separately, you know, if that's the broader opportunity in your assessment, what would be kind of the smaller, more focused near-term opportunity, whether that's in terms of number of patients or facilities, just kind of curious how you plan on kind of attacking that new opportunity.
Sure. Understood. Using EksoNR for MS is not a new thing. You know, we've had our customers and researchers using the product for that purpose sort of out of band historically. What the new MS indication gives us is the ability to market this. What that means is we can go back into our existing customers that we have and we've already started this with our sales and our clinical teams, to go back into our existing customers and let them know about the great potential outcomes that they can have with MS patients. You know, near term, you know, this is something that we're doing is just getting the word out to our existing customers.
As we, you know, move a little bit further out, again, this expands our reach into a broader continuum of care and allows us to, you know, knock on the doors of some of the outpatient facilities as well as this, you know, better aligns with their patient population. It's, you know, from a, you know, resourcing perspective, you know, one of the strengths that Ekso has is our great commercial team, including our sales and our clinical teams and as well as our marketing team. We are basically leveraging those teams and getting them out there to be able to spread the good word of how we can help more patients.
No, got it. Appreciate that. Maybe following up on that, now that you are able to market this on label, it sounds like you've already kind of deployed marketing and commercialization resources towards this. So I guess the question is, in terms of OpEx and incremental overhead and potentially changing any sort of marketing strategy, how should we think about kind of the run rate of SG&A going forward for the balance of the year?
Yeah. You know, we don't anticipate any changes, relative to this, indication. We've anticipated this for some time.
Sure. Got it. Just lastly, housekeeping. If it's handy, what was depreciation stock comp in the quarter just so I can back into EBITDA? Thank you.
One moment. We are just digging up the detail on that right now. One moment.
Maybe while we're digging that up, Scott, just lastly, in terms of the new headquarters, sorry, what did you say about Q3? I mean, is that maybe you could just outline briefly again the timing of that.
Sure. Timing. We have been in a long-term lease over here in Richmond and in a rather interesting and sizable facility. You know, we are extremely excited over finding our new location in San Rafael. We're in Richmond. Currently San Rafael is just over the Richmond Bridge, not far from where we are. We went from one side of the bay to the other side of the bay over in Marin County. The facility is right sized for our organization. It just fits our needs much better than the facility that we've been in.
On top of all that, it represents a savings to us, you know, as well. You know, it's a positive move for us but we are making this relocation and we're doing this in Q3. We'll be officially in before the end of Q3. Does that answer your question, Kyle?
That's perfect.
Okay.
Thank you.
Okay, now back to your depreciation question. Jerome can answer this.
Depreciation was about $125 thousand and then stock comp was $519 and it's all for Q2.
Excellent. Okay, great. Hey, thanks, guys, for all the updates and congrats on the quarter.
Yeah, we appreciate it, Kyle. Thank you.
Thank you. We've reached the end of our question and answer session. I'd like to turn the floor back over to Scott for any further closing comments.
Thank you, Kevin and thanks to everyone for joining us today. We're thrilled with the progress and milestone achievement in our second quarter, highlighted by the largest multi-unit capital purchase order in our company's history. We're pleased to have accelerated our revenue growth in the quarter. Additionally, receiving 510(k) clearance from the FDA to market our EksoNR for use in patients with MS not only gives us a greater pool of patient access but it allows them to have this as part of their rehabilitative solutions. It also significantly expands our market opportunity. Underscoring our success is our ability to execute under difficult market challenges that continue to impact the broader macro market. We're doing this for the patients who desperately need treatment options and are pleased that we have helped elevate the standard of care for neurorehabilitation.
Strengthening relationships with top network operators, we are generating more multi-unit deliveries that have yielded a stronger pipeline to support our future growth. Combined with deeper customer relationships across a variety of industrial verticals for EVO and proactive management of supply chain constraints, we are poised to sustain our momentum through the second half of 2022 and beyond. In closing, I'd like to express my gratitude to the entire Ekso team and our valued shareholders. We look forward to providing additional updates throughout the year. Thank you all and have a great day.
Thank you. That does conclude today's teleconference and webcast. You may disconnect your line at this time and have a wonderful day. We thank you for your participation today.
