Thank you, Lauren, and good morning, everyone. Let's begin with a brief review of our third quarter results. We are very pleased to report consolidated sales increase 2.8% to $3.04 billion as we continued to gain market share. Comp store sales increased 1.7% on top of a 6.5% increase in the same period last year. Our strong comps were driven by a 1.1% increase in transactions and a 0.6% increase in average ticket. Collectively, our back-to-school categories did very well and we're pleased with the results from our House of Sport locations. Our noncomp sales growth of roughly 110 basis points this quarter was primarily driven by sales at Moosejaw.
On a non-GAAP basis, gross profit in the third quarter was $1.07 billion or 35.1% of net sales and improved 88 basis points compared to last year. This improvement was driven by lower supply chain costs, which leveraged 78 basis points. Merchandise margin increased 23 basis points and as expected, this increase was primarily driven by anniversary of our clearance activity from last year and partially offset by higher shrink of approximately 50 basis points. To be clear, absent the shrink headwind, our merchandise margin would have increased over 70 basis points. [ Combating theft ] remains a top priority, and we continue to invest in efforts to keep our stores, teammates and athletes safe.
On a non-GAAP basis, SG&A expense increased $50.1 million to $729.9 million and deleveraged 102 basis points compared to last year. This was favorable versus our expectation due to better-than-expected sales, targeted actions to control discretionary costs and benefits from our business optimization actions.
As we have highlighted on prior calls, the year-over-year deleverage this quarter was driven by our investments in our base rate, talent and technology to create a better athlete experience as well as investments in marketing. These areas of investments were partially offset by $8.2 million of expense reduction or 26 basis points of leverage associated with changes in the investment value of our deferred compensation plan, which is fully offset in other income.
Interest expense was $14.4 million, a decrease of $11.7 million compared to the same period last year. This decrease was primarily due to the inducement charges incurred in the prior year related to the exchange of our convertible senior notes and the interest savings this year from the retirement of those notes.
Other income totaled $10.1 million compared to $4.8 million in the same period last year. This $5.3 million increase in income was driven by a $13.3 million increase in interest income as a result of higher average interest rates on our cash and cash equivalents. This increase to other income was partially offset by $8.2 million expense increase from change in the value of our deferred compensation plans, which fully offsets the SG&A expense reduction I mentioned earlier.
Driven by our strong sales, higher gross margin, along with lower interest expense, non-GAAP EBT was $321.1 million or 10.6% of net sales. This compares to an EBT of $304.2 million or 10.3% of net sales in 2022. In total, we delivered non-GAAP earnings per diluted share of $2.85. This compares to a non-GAAP earnings per diluted share of $2.60 last year, an increase of 10%.
As Lauren said, to continue fueling our long-term growth, we have optimized our organization to better align our talent, organizational design and spending in support of our most critical strategies while also streamlining our overall cost structure.
First, we are resourcing DICK'S for growth. As we have discussed -- as we discussed on our last call, during the third quarter, we took actions to change our resourcing and organizational structure, primarily at our customer support center.
Second, we are taking steps to optimize our outdoor specialty business and are forming one team that will support the operations of Public Lands and Moosejaw. This will allow us to quickly leverage the best practices across our outdoor specialty business to drive growth while operating more efficiently.
We started to see the SG&A benefits from these actions during the third quarter and expect to see continued benefits into Q4 and 2024. These actions, along with our overall focus on improving productivity and reducing discretionary costs will help enable us to significantly moderate our SG&A expense growth in 2024 as compared to this year.
As a result of these actions, we incurred pretax charges totaling $52.5 million during the third quarter. This included a $6.3 million of inventory-related write-down associated with rationalization of non-go-forward Moosejaw inventory. These charges were included in our GAAP earnings per diluted share of $2.39. For additional details on this, you can refer to our non-GAAP reconciliation table of our press release that we issued this morning.
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 decreased 2% compared to Q3 of last year. Our inventory is well positioned, and we are excited about our assortment for the holiday season.
Turning to our third quarter capital allocation. Net capital expenditures were $151 million and we paid $81 million in quarterly dividends. We also repurchased 3.5 million shares of our stock for $388.1 million at an average price of $112.46. Year-to-date, we have returned over $900 million to shareholders through share repurchases and dividends.
Let me wrap up with our outlook for 2023. As Laura noted, as a result of our Q3 performance, we are raising our full year outlook. We are confident in our key strategies and are well positioned to execute against what is in our control. At the same time, we are being appropriately cautious, particularly at the low end of our expectations, considering the ongoing macroeconomic uncertainties.
For the year, we now expect non-GAAP earnings per diluted share in the range of $12 to $12.60 compared to our prior expectation of $11.50 to $12.30. This continues to include approximately $0.20 coming from the 53rd week. In addition, we now expect comparable store sales in the range of positive 0.5% to positive 2% compared to our prior expectation of flat to positive 2%. Including the 53rd week, we expect roughly 250 basis points of noncomp sales growth for the full year. Specifically, this includes approximately $150 million in sales from the 53rd week, which is a smaller than average sales week for us.
At the midpoint, non-GAAP EBT margin is expected to be approximately 10.4% compared to our prior expectation of 10.2%. We expect modest improvement in gross margin for the full year, which continues to include an approximate 50 basis point unfavorable impact from higher shrink compared to 2022.
Specific to Q4, we expect to deliver continued gross margin and merch margin expansion on a year-over-year basis with some improvement versus our Q3 expansion. We also continue to expect SG&A expenses to deleverage on a full year, primarily due to the proactive investments in our growth strategies. Specific to Q4, we expect SG&A to deleverage by a similar magnitude as the third quarter.
Our earnings guidance is based on an effective tax rate of approximately 21% and an approximately 86 million average diluted shares outstanding compared to our prior expectation of approximately 87 million average diluted shares outstanding. In addition, we expect net capital expenditures between $550 million to $600 million for the year. As part of our business optimization, we incurred pretax charges totaling $52.5 million during the third quarter and currently expect to incur charges of approximately $10 million in fourth quarter. These charges were excluded from today's non-GAAP outlook. We are still conducting our business optimization review, which we expect to be completed during fiscal 2023.
This concludes our prepared comments. Thank you for your interest in DICK'S Sporting Goods. Operator, you may now open the line for questions.
