Sure. Thanks, Chris, for the question. Let me talk a little bit about how we see gross margin progressing through the year. So we expected last quarter, and we continue to expect now, that Q2 is going to be our most challenging quarter in terms of margin pressure. And you saw that with our margins down about 33%. We continue to expect sequential improvement as we move throughout the balance of the year. And we continue to expect by Q4, we are in a position where we start to rebuild margins, and then we'd expect that to continue into fiscal year '23. Now to your question about what are the drivers in the back half of the year that will drive that sequential improvement.
I'd point to a few. The first is pricing. Pricing will continue to build in terms of the value it generates for us as we move through the year. In Q1, it was fairly limited. It was about 50 basis points of benefit to margin. This last quarter, it was about 100 basis points. I think by Q3, it's starting to approach 200. It's probably still a little bit south of 200. And by the fourth quarter, I think the benefit will be well over 200 bps to gross margin. So you're going to see that building value from the pricing actions we have taken or the additional ones we announced today that we'll take over the back half of the year.
In addition, when you think about our cost savings program, we're on track to have another very good year, but you will see that phasing in a little bit more back-half weighted. And so in the front half of the year, we generated about 80 to 90 bps of benefit. You should see that north of 100 bps in the back half of the year, and that's just the timing of the projects, how they happen to play out this year. And then the other item I'd point to is, as you look at the cost inflation we're dealing with, Q2 was the most challenging quarter from a year-over-year perspective.
As we get to the back half of the year, while we're still operating in an inflationary environment, the year-over-year change is much smaller because we really started to see a run up in commodities at the beginning of calendar year '21 with the ice storm in Texas. And so on a sequential basis in Q3 and Q4, those increases in both commodities, transportation, in manufacturing, they'll be a lower hit to margin as we move through the quarters. And then finally, Chris, to your last comment, which is spot on as it relates to mix. We've talked about this for the last few quarters.
We had a temporary benefit during the pandemic when we significantly reduced the number of products we offer to increase supply. As we are reintroducing our full line of products, including multipacks, that does have a mix hit. There will be about four quarters of that unwinding that temporary benefit, which will go through Q3, the current quarter end. And by the fourth quarter, we've lapped that, and we should not see a mix drag to margins, so we'll also get that benefit.
And then the last one is, as you mentioned, deleveraging. With volumes down in the front half of this year, there was some deleveraging that impacted margins. But in the back half of the year, we expect volumes to be flat, if not up. And so we should not expect that drag either. And so those are the elements of how we move through the year and why we expect to see margins building as we move through Q4.
