Aaron, it's Paul here. So yes, we did lower slightly our guidance on our guidance on both OpEx and CapEx and, as we stated, in responding to a challenging macro environment. I mean, you will have noticed that we have been ramping up our costs, $38 million total costs in Q2, $14 million higher than the prior year. And last year, you can see that the pace has been from last year, you can see that the pace has been increasing. We're investing, as we stated, in research and development product, development, next-generation products, MEAs, plates, stacks, modules. Also focused on cost or product cost reduction, as well as scaling up our production and manufacturing scalability facilities and market development. Also investing in Europe and the U. K. with our corporate development activity as well. So yes, we did say that we would be reducing it. And when we say a challenging macro outlook that encompasses a few different things. It not only encompasses sort of the prudence on any sort of lower priority, less essential spending that we have, so really scrutinizing the prioritization. But that is, by no means, as a message that we are backing off on our commitment to scale up and invest in our products. We think that's extremely important, especially as we talk to customers and secure larger orders, they're looking for us to be able to have the best technology, be able to produce it at scale and at quality. And so we will continue to focus on that. So -- but there is maybe a few areas where we could cut back without impacting that objective. But the other area, too, is that we acknowledge also that there have been supply chain challenges, right? That could -- that we see could persist into 2023. So while we are ordering parts and production equipment and such, it is taking longer. The lead times are getting pushed out due to supply chain challenges, which will impact spending in the year. And it also -- the final area is it also acknowledges the reality of us onboarding really well-qualified people. We've done a great job this year and scaled up, I think, by about net 80 people, mostly in engineering, but it's slightly behind the pace we thought we would be at. We'll continue to press forward and look for those people, but it is a reality of the environment we're in. So taking that all together, we see our spending to be slightly less than the guidance that see our spending to be slightly less than the guidance that we provided on both OpEx and CapEx.
