Thanks, Jen. Good morning, everyone. As Jay mentioned, third quarter results marked continued progress on our strategic priorities to grow our brands and set us up for improved profit flow-through. Strong brand momentum, combined with actions taken on our profit improvement initiatives, resulted in improved gross margins and operating income year-over-year. We entered in the quarter with momentum that continued into the early holiday season, fueling a strong top line result.
Consolidated revenue of $1.3 billion was up 5% to last year, and comparable sales also rose 5%. Operating income of $125 million reflected a 9.6% operating margin. Gross profit of $544 million increased $64 million, representing a gross margin of 41.8%, up 310 basis points to last year. As Jay noted, we achieved some of our highest merchandise margins on record, reflecting strong demand, lower costs and a number of benefits from our profit improvement initiatives.
Inventory discipline resulted in lower markdowns as we maintained healthy promotions. With the change in our clearance model announced last quarter, we continue to sell through end-of-season merchandise at better margins. We also saw leverage on rent, reflecting our focus on strengthening fleet productivity at AE and the ramp-up of new Aerie stores as well as delivery, distribution and warehousing costs with efficiencies across several key metrics, including lower shipments per order and lower cost per shipment.
SG&A expense of $362 million was up 16% from last year and in line with guidance. Consistent with strong business trends, roughly half of the increase was driven by incentive expense after 0 accruals last year. As discussed last quarter, incentives are weighted to the back half of this year. The payroll also increased largely due to higher wages. Depreciation was up year-over-year and in line with guidance provided last quarter, primarily reflecting our investment in new stores.
As noted previously, we have reset incentives to reflect improving business performance with incentives now on our base and an ongoing focus on cost efficiencies, we're well positioned to leverage our expense based on modest top line growth next year. EPS for the third quarter of $0.49 per share.
Turning to our brands. Aerie revenue and comparable sales increased 12% in the third quarter, a positive noncomp lift from these stores was offset by lower third-party fell off, reflecting greater inventory control and our shift to a more profitable clearance model. Aerie's operating margin of 19.3% hit an all-time high, expanding over 3 points to last year as the brand continued to scale, and we saw improved markups, lower markdowns and early benefits from the clearance shift. American Eagle revenue and comps increased 2% with the operating margin expanding 70 basis points to 21.5%. As we discussed on numerous occasions, our focus over the past several years has been strengthening the profitability of the AE brand. I'm extremely pleased with the progress we've made, expanding profit margin by 400 basis points since third quarter of 2019.
We're now turning our attention to growing the top line with a sharp eye on profit flow-through. Consolidated ending inventory cost was down 4% compared to last year with units down 3%. Inventory levels remain healthy and controlled as we maintain buying discipline and case demand. We ended the quarter with a balance sheet in a strong position, including $241 million of cash and total liquidity of $875 million, including our revolver.
Capital expenditures totaled $43 million, and we continue to expect full year CapEx to be in the range of $150 million to $175 million. Our plan for our consolidated store count in 2023 remains roughly flat to last year, reflecting approximately 25 new Aerie store openings offset by approximately 25 net closures for the AE brand.
Before I move on to our outlook, I'd like to provide more color on our ongoing profit improvement work. Last quarter remained an important change to our clearance model. This is tracking in line with plan to generate $25 million in savings in 2023 and $50 million in savings on an annualized basis. As we continue to lock down efficiencies that have supported our gross margin expansion, other significant work streams within SG&A have also been identified and are being actioned on.
We are instilling an internal culture around continuous improvement and expense management. The results of which are incorporated into our 2024 plans. As a result, next year, we expect to drive continued gross margin expansion, leverage on SG&A and depreciation, operating rate expansion and healthy earnings growth, structuring the business to deliver this at low single-digit revenue growth. A more positive trend would drive incremental leverage and profit flow-through. We'll give further details in future months as we provide our specific expectations for 2024 and beyond in the spring.
Quarter-to-date, we are seeing sustained momentum across our brands with revenue up in the mid-single digits. Additionally, we continue to make good progress in executing on profit improvement initiatives. With this background, we're raising our full year outlook for operating income to the high end of prior guidance. We now expect to be in the range of $340 million to $350 million. This reflects revenue up mid-single digits with comps up low to mid-single digits.
For the fourth quarter, this implies operating income in the range of $105 million to $115 million, with revenue up in the high single digits, including a 4-point tailwind from the 53rd week. Comp sales are projected to be up in the mid-single digits. SG&A is expected to be up approximately 20%, including a 5-point impact from the 53rd week. As previously discussed, it also includes higher incentive accruals, which are skewed to the back half of this year. As Jen mentioned, we look forward to providing more color on our long-term strategic priorities and financial goals at our Spring Investor Meeting.
With that, I'll open it up for questions.
