Thank you, David. Good morning, everyone. On Slide 6, net sales in the first quarter were $213.5 million, up 53.5% from a year ago, which was the quarter most heavily impacted by the pandemic. This sales level was near the midpoint of our guidance for first quarter revenue of approximately $212 million to $217 million. While we continue to see demand improve sequentially, like many other industrial companies, we experienced supply chain delays, which impacted revenue levels in the quarter. This was also the first quarter that the Dorner acquisition is included in our results. As David mentioned, Dorner exceeded our expectations, delivering over $34 million of revenue in a truncated quarter, given that we closed the acquisition on April 7.
Looking at our sales bridge. Sales volume was up $31 million or 22.5%. We also realized positive pricing as we saw year-over-year pricing improve by 1.4%. Foreign currency remains a tailwind and increased sales by 5% or $6.9 million. Let me provide a little color on sales by region. For the first quarter, we saw sales volume increase in the U.S. by nearly 28%. We realized 90 basis points of pricing. As a reminder, we have not yet benefited from the second price increase that we announced the last week of June as many of our shipments in the quarter were sitting in backlog at the start of the quarter.
Outside of the U.S., sales volume was up approximately 16% and pricing was up 2%. By region, sales volume was up 51% in Canada, up 39% in Latin America, up 12% in EMEA and up 7% in APAC. We are monitoring inflationary pressures globally and have announced additional price increases in the U.S. and Canada effective in August. In addition, we are looking at additional surcharges in Europe later in the quarter.
On Slide 7, we saw our gross margin improve sequentially to 34.7%, which compares with 34.4% in the fiscal fourth quarter. We achieved a record adjusted gross margin of 36.3%. This quarter, we incurred $3 million of inventory step-up expense and $500,000 of acquisition deal and integration costs that hit cost of sales. As part of purchase accounting, we value Dorner assets and liabilities at fair market value. The $3 million of inventory step-up expense represents the difference between the fair market value of Dorner's inventory and the actual inventoriable cost. This amount is then expensed based on inventory turns, which was all recognized in our first quarter and won't impact future quarters.
Overall, Dorner was 80 basis points accretive to adjusted gross margin this quarter. In addition to Dorner, adjusted gross margins reflected the operating leverage from higher sales volumes, which led to favorable year-over-year productivity in our factories. This was partially offset by the negative impact of supply chain challenges.
We are still benefiting from our 80/20 process, which contributed approximately $1.3 million incremental year-over-year gross profit expansion in the quarter largely from factory closure savings. We are focused on product line simplification this year and are making good progress with SKU and component reductions. Unfortunately, this part of the 80/20 process takes longer to realize benefits, but will pay dividends over a longer horizon.
Let's now review the quarter's gross profit bridge. First quarter gross profit of $74.1 million was up $29.3 million compared with the prior year. This was driven by several factors. First, Dorner contributed $14 million of gross profit. Sales volume added $11.6 million to gross profit compared to a year ago. We also saw positive productivity net of other cost changes of $2.9 million despite some supply chain challenges that I referenced. Foreign currency translation added $2.4 million to gross profit. Pricing net of raw material inflation was positive $700,000, which was offset by higher tariffs on products coming from China of $1 million. In the prior year quarter, we had factory closure and business realignment costs, which did not repeat. This quarter, we incurred $500,000 of acquisition integration costs and inventory step-up expense of $3 million. And as I previously mentioned, the inventory step-up expense will not reoccur in the future.
As shown on Slide 8, our SG&A costs were $57.2 million in the quarter or 26.8% of sales. Included in this total were $8.7 million of Dorner acquisition-related costs and $600,000 of business realignment costs, which we have included as pro forma items in our adjusted operating income, adjusted EBITDA and adjusted EPS calculations.
Excluding these onetime costs, our SG&A costs would have been $47.9 million or 22.4% of sales. I would point out that this number also has an incremental $5.9 million of our SG&A costs from the Dorner acquisition. This means that legacy Columbus McKinnon incurred $42 million of our SG&A costs, which was comparable to $42.3 million recorded in Q4, excluding acquisition deal costs and business realignment costs incurred in Q4.
For the fiscal second quarter, we are increasing our Q2 estimate for RSG&A to $52 million, which includes the full impact of the Dorner acquisition. This includes additional investments and strategic growth initiatives as well as higher variable selling costs, which reflect a higher level of sales in Q2 compared to Q1.
Turning to Slide 9. Adjusted operating income was $23.6 million. Adjusted operating margin was 11.1% of sales, up 750 basis points from the prior year. This margin expansion is driven by the operating leverage in the business, incremental pricing and the Dorner acquisition. At current FX rates, we expect total amortization expense of $6.3 million per quarter with Dorner.
As you can see on Slide 10, we recorded a GAAP loss per diluted share for the quarter of $0.27. Adjusted earnings per diluted share were $0.69, which were up substantially from $0.17 per share in the prior year and up $0.09 per share sequentially. I want to highlight that for this quarter and going forward, we are adding back amortization expense from the income statement on a tax-affected basis to our adjusted earnings per diluted share calculation. In Q1, this added $0.18 to adjusted earnings per diluted share. All periods on this chart have been restated for this. We feel that this is a better indicator of the true cash earnings performance of the company as we intend to be programmatic with our M&A strategy.
On a GAAP basis, we recorded the cost of debt refinancing this quarter of $14.8 million and acquisition deal and integration costs of $9.2 million. We also had the inventory step-up expense that I previously discussed. With the new financing that we completed in May, we expect interest expense of approximately $4.7 million in the second quarter and our diluted shares outstanding are anticipated to average 29 million shares in the second quarter as well. Our tax rate on a GAAP basis is expected to be in the range of 21% to 23%, and we will continue to use 22% as our tax rate for non-GAAP adjusted earnings per share.
On Slide 11, our adjusted EBITDA margin continues to increase and was 13.7% on a trailing 12-month basis. In the first quarter, with Dorner, adjusted EBITDA margin was 16%. Dorner was accretive to our adjusted EBITDA margin by 190 basis points. Our return on invested capital also continues to improve and was 7.8% in Q1, which slightly exceeded our current WACC. We continue to target a 19% EBITDA margin and expect our ROIC to be double-digits in FY '23, excluding the impact of future acquisitions. We remain highly confident that our strategy will enable us to drive profitable growth and achieve these objectives.
Moving to Slide 12. We used $11 million of free cash flow this quarter, which included a cash outflow of $10.9 million related to acquisition deal costs which were paid in the quarter. As sales have increased, we have also increased our working capital investment by approximately $26 million, which included additional investments in inventory to meet rising demand. Our working capital as a percent of sales was 12.5% of sales, which was in line with what we were expecting. CapEx was $3.6 million in the quarter. We expect CapEx of $20 million to $25 million for the full year.
Turning to Slide 13. As we discussed in May, we refinanced the capital structure post-Dorner acquisition, which included a bridge loan, an equity offering and a new term loan B. The new $450 million term loan B carries an interest rate of LIBOR plus 275 basis points with a 50 basis point LIBOR floor. This gives us a low-cost, flexible capital structure that will serve us well for the coming years.
As of June 30, on a pro forma basis, which includes Dorner's June LTM adjusted EBITDA, but excludes expected cost synergies, our net leverage ratio was approximately 3.0x. We expect to hit our target leverage ratio of 2x within 2 years, excluding any additional acquisitions. Finally, our liquidity, which includes our cash on hand and revolver availability, remained strong and was approximately $170 million at the end of June.
Please advance the Slide 14, and I will turn it back over to David.
