Thanks, John. In many ways, the environment today feels completely different than 3 years ago when the pandemic was just beginning and no one knew what to expect, but today even as the pandemic feels further and further behind us, we continue to face elevated macro uncertainty and volatility as the world continues to transition toward a new normal. From a macro perspective, inflation remains high and stubbornly persistent, having recently peaked at decades high levels. To control this inflation, the Federal Reserve has been raising interest rates at an unprecedented pace. But for now, despite the building economic pressure from both inflation and higher interest rates, the U.S. unemployment rate is lower today than it's been in 50 years. And as Christina mentioned, consumer spending patterns continue to evolve, putting significant pressure on our discretionary categories.
While I'm guessing we're all looking forward to the day when economic conditions begin to stabilize and normalize, I'm pleased that today, even in the face of all these challenges, we're continuing to see deeper engagement from our guests. That's most visible on our traffic, which grew just under 1% in Q1 and has now grown for 12 consecutive quarters. In fact, since 2019, prior to the pandemic, first quarter total sales have increased more than 43%. The vast majority of that growth is the result of an increase in sales per square foot over that time of which a significant portion has been driven by traffic.
Total sales grew 0.5% in the first quarter, reflecting flat comparable sales, combined with the contribution from new locations. Total revenue growth of 0.6% reflected sales growth, combined with double-digit growth on the other revenue line, led by our Roundel ad business. As Brian mentioned, sales trends softened over the course of the first quarter. More specifically, we began the quarter with positive comp growth in the month of February and then saw the trends soften into low single-digit declines by the end of April and so far into May.
Our first quarter gross margin rate of 26.3% was about 60 basis points higher than a year ago. Among the drivers, we saw more than a percentage point of favorability in merchandising, driven primarily by a reduction in freight and transportation costs, along with the benefit of retail pricing and a lower clearance markdown rate as we compared over last year's inventory actions. We also saw a small gross margin rate benefit from lower digital volume and a more favorable mix of lower cost same-day fulfillment.
Offsetting those 2 sources of benefit, shrink reduced our gross margin rate by a full percentage point compared with a year ago. As Brian highlighted, pressure from shrink has continued to increase, and we now expect that if current trends continue, shrink will reduce our full year profitability by more than $500 million compared with last year. One note, the impact of merchandise mix on our first quarter gross margin rate was approximately neutral as the rate impact of sales declines in our highest-margin categories was offset by sales declines in lower-margin rate categories.
Consistent with the guidance we provided for the quarter, our first quarter SG&A expense rate was 19.8%, up about 90 basis points from a year ago. This increase reflects our continued purposeful investments and paying benefits for our team, combined with inflationary cost pressures throughout our business against a backdrop of flat comparable sales, partially offset by the benefit of productivity increases and strong expense discipline across the company. Our first quarter D&A expense rate was down about 10 basis points, reflecting lower accelerated depreciation related to our remodel program compared with last year. Altogether, our first quarter operating income rate to 5.2% was higher than expected, due primarily to upside in our gross margin rate as the benefits from lower freight and transportation costs and our efficiency efforts offset a higher-than-expected impact from shrink.
As John mentioned, Q1 ending inventory was about 16% lower than a year ago. Within that inventory number was a decline of more than 25% in discretionary categories, reflecting the excess inventory we were carrying last year and the cautious approach we are taking this year. Partially offsetting the decline in discretionary inventory are the purposeful inventory investments we're making in our frequency categories, along with some strategic bets in support of long-term share opportunities. We believe our cautious inventory approach has served us well so far this year and will continue to be the right approach going forward.
As I turn now to capital deployment, I'll start where I always do, by reiterating our long-standing priorities. First, we fully invest in our business in projects that meet our strategic and financial criteria. Second, we support the dividend and look to build on our record of annual increases, which we've maintained since 1971. And third, only after we've supported those first 2 priorities, we deploy any excess cash to repurchase shares over time within the limits of our middle A credit ratings. Regarding the first priority, we made capital investments of $1.6 billion in the first quarter as we continue to remodel stores, open up new locations, build upstream inventory replenishment capacity and ramp up our sortation center strategy.
With 1 quarter of the year behind us, we continue to expect our full year CapEx will be in the $4 billion to $5 billion range. Regarding the second priority, we paid dividends of $497 million in the first quarter, up from $424 million last year, driven by a 20% increase in the per share dividend, partially offset by a decline in average share count.
And finally, given the impact of the current environment on our financial performance, we didn't repurchase any shares in the first quarter. In the near term, we'll maintain that approach and don't intend to resume repurchase activity until it's compatible with our long-term credit rating goals.
On that note, I'm pleased with our progress in strengthening our balance sheet. Even as profitability remains well below our long-term potential, we've already seen an encouraging improvement in our operating cash flows. More specifically, our operations generated $1.3 billion of cash in Q1 in stark comparison to a year ago when our operations absorbed $1.4 billion. This dramatic year-over-year improvement was driven almost entirely by changes in our inventory investment compared with last year.
And finally, I want to end my review of the quarter with our after-tax returned on invested capital. For the trailing 12 months through the first quarter of this year, our after-tax ROIC was 11.4% compared with 25.3% a year ago, reflecting both the change in profitability and the increase in working capital we began to see a year ago. As we move further into the year, we expect to see higher profitability than a year ago and continue to benefit from the inventory efficiency reflected in this quarter's cash flow. Based on these expectations, we anticipate a recovery in the ROIC metric this year and expect to continue building back toward our longer-term potential in 2024 and beyond.
So now let me turn to our expectations for Q2 and the full year. As I mentioned, on the sales line, we experienced notably softer comp trends as we exited the first quarter and moved into May. As a result, we're anticipating second quarter sales in a wide range centered around a low single-digit decline, consistent with those recent trends. In terms of profitability, we're expecting a range of possibilities as well.
On the gross margin line, we believe that many of the same trends that emerged in Q1 will continue in the second quarter, including a meaningful tailwind from freight and transportation costs, and a significant headwind resulting from inventory shrink. Similarly, on the SG&A expense line, we'll continue to face broad-based inflationary pressures and expect to benefit from efficiency efforts and cost discipline across our team. However, if our second quarter comp sales end up declining in the low single digits, which is where they are trending currently, we'll see greater SG&A rate pressure related to cost deleverage than we experienced in Q1.
In light of all of these expectations, we believe our Q2 operating margin rate will be much higher than the very low rate we earned a year ago, but lower than the 5.2% we saw in Q1. Altogether, our expectations translate to a second quarter GAAP and adjusted EPS range of $1.30 to $1.70. As we look beyond Q2, we continue to believe that we entered this year with the appropriate level of caution planning conservatively in light of a tough macro environment and rapidly changing consumer trends. While we're facing some clear headwinds in the short term, we also have multiple actions underway to mitigate them, including ongoing efficiency work and cost saving efforts that we expect to flow into the P&L in the second half of the year.
While we feel good about these efforts, we also remain cautious on the overall environment in light of the macro industry pressures we've outlined today. Taking this all into account, we are maintaining the full year guidance we provided at our Financial Community Meeting in February. Namely, we're planning for full year comparable sales in a wide range centered around flat. We expect to grow our full year operating income by $1 billion or more, and we expect our business to generate full year GAAP and adjusted EPS of $7.75 to $8.75.
As I get ready to turn the call back over to Brian, I want to reiterate my confidence in our longer-term prospects for profitable growth. Even today against a very challenging backdrop, we're starting to assemble the building blocks for a recovery in our operating margin rate back towards its longer-term potential. And while spending pressures in discretionary categories are currently outweighing the continued strong growth we've seen in our frequency categories, we're confident that the economy and the consumer will stabilize over time and will once again benefit from growth in the more discretionary portion of our assortment.
In the meantime, we have the capacity to navigate this environment with a strong balance sheet and a resilient business model. We have the right long-term strategy, and we're privileged to work with the best team in retail. I want to express my sincere thanks to our entire team. You are, by far, our most valuable long-term asset.
With that, I'll turn it over to Brian.
