Thank you, Lauren, and good morning, everyone. Let's begin with a brief review of our third quarter results.
We are excited to report a consolidated sales increase of 7.7% to $2.96 billion. As Lauren noted, comparable store sales increased 6.5% on top of a 12.8% increase in the same period last year, a 23.2% increase in Q3 of 2020 and a 6% increase in Q3 of 2019. Our strong comps were driven by a 3.7% increase in transactions and a 2.8% increase in average ticket.
Within our portfolio, the back-to-school categories did very well, driven by our differentiated assortment across footwear, apparel and team sports. When compared to 2019, sales increased 51%. This reflects a significant sequential acceleration in our sales trends versus 2019 from recent quarters.
Gross profit in the third quarter was $1.01 billion or 34.22% of net sales and declined 423 basis points versus last year. However, it increased 463 basis points over Q3 of 2019. As expected, the year-over-year decline was driven by merchandise margin rate decline of 438 basis points.
During the quarter, we focused on cleaning up some targeted inventory overages due to late arriving spring products. We moved excess apparel inventory to our value chain concept and have been very successful in liquidating much of this product. We intend to continue addressing this overage in Q4 in order to start 2023 clean.
Our Q4 merchandise margin expectations are appropriately reflected within our annual outlook. Compared to 2019, our merchandise margin rate is 141 basis points higher driven by a differentiated assortment, combined with our sophisticated and disciplined pricing strategies and a favorable product mix. Because of these structural drivers, we continue to expect our merchandise margin rate to remain meaningfully higher than pre-COVID levels on an annual basis.
SG&A expenses were $679.7 million or 22.97% of net sales and leveraged 3 basis points compared to last year on the increase in net sales. The $48 million increase in SG&A dollars was driven by investments in hourly wage rates, talent and technology to support our growth strategies.
Interest expense was $26.1 million, an increase of $20.1 million on a non-GAAP basis compared to the same period last year. This increase was primarily due to $13.8 million of interest expense related to our $1.5 billion senior notes issued during Q4 of 2021. The current quarter also included $8.8 million of inducement charges related to our exchange of approximately $221 million of outstanding principal of our convertible senior notes.
Driven by a structurally higher sales, expanded margins and operating efficiency compared to pre-COVID levels, EBT was $304.1 million or 10.28% of net sales. This compares to a non-GAAP EBT of $59.9 million or 3.05% of net sales in 2019 and an increase of $244.2 million or 723 basis points as a percentage of net sales.
In total, we delivered non-GAAP earnings per diluted share of $2.60. This compares to a non-GAAP earnings per diluted share of $3.19 last year and represents a 400% increase over 2019's non-GAAP earnings per diluted share of $0.52.
Now looking to our balance sheet. We ended Q3 with approximately $1.4 billion of cash and cash equivalents and no borrowings on our $1.6 billion unsecured credit facility. Our quarter end inventory levels increased 35% compared to Q3 of last year. As a reminder, we were chasing inventory last year amidst industry-wide supply chain disruptions. Therefore, the better comparison is against Q3 of 2019. And compared to Q3 2019, our 51% increase in sales was well ahead of our 31% increase in inventory. Our inventory is healthy and well positioned.
Now turning to our third quarter capital allocation. Net capital expenditures were approximately $100 million and we paid $41 million in quarterly dividends. During the quarter, we exchanged approximately $221 million of outstanding principal of our convertible senior notes for cash and unwound the corresponding portion of the convertible note hedge and warrants or 4.3 million shares of our common stock. After completing this exchange, we have taken out approximately $421 million with approximately $154 million in aggregate principal of the convertible notes still outstanding.
Beyond retiring nearly 3/4 of our convertible notes, year-to-date, we have returned $485 million to shareholders through dividends and share repurchases while continuing to invest in the profitable growth of our business.
So let me wrap up with our outlook for 2022. As a result of our strong Q3 performance and the quality of our assortment for the holiday season, we are raising our 2022 guidance. Importantly, our updated outlook continues to incorporate an appropriate level of caution given the uncertain macroeconomic backdrop. For the year, we now expect comparable store sales in the range of negative 3% to negative 1.5% compared to our prior expectation of negative 6% to negative 2%.
In addition, we now expect non-GAAP earnings per diluted share in the range of $11.50 to $12.10 compared to our prior expectation of $10 and $12. EBT margin is now expected to be approximately 11.4% at the midpoint, more than double our 2019 rate. Our earnings guidance assumes an effective tax rate of about 25% and is based on approximately 88 million average diluted shares outstanding.
In closing, we are very pleased with our Q3 results, and we remain very enthusiastic about the future of DICK'S. This concludes our prepared comments. Thank you for your interest in DICK'S Sporting Goods. Operator, you may now open the line for questions.
