Thanks, Jen, and good afternoon, everyone. As I recap our performance, it's important to note the impact of operating 1 less week in 2018 in keeping with the retail calendar. This adversely affected both sales and operating profit for the year and the fourth quarter.
Throughout 2018, American Eagle and Aerie demonstrated strong brand performance. Total revenue reached record highs for the fourth quarter and the year, with broad-based strength across regions and channels. Investments in our store experience, our people and marketing have contributed to greater consistency and improved results across the business.
In the fourth quarter, we delivered strong quality of sales metrics and reduced markdowns in what was a promotional holiday season. Please keep in mind that my comments will focus on the adjusted financials, which exclude certain items as detailed in the press release and tables on Pages 6 through 9 of the investor presentation.
Now looking at the fourth quarter. Total revenue for the 13 weeks increased 1% to $1.24 billion compared to $1.23 billion for the 14-week period last year. Total revenue grew by $15 million despite operating with 1 less week, which approximated $60 million in lost revenue. Comparable sales for the 13 weeks increased 6%, following an 8% in the prior year. The quarter marked our 16th consecutive quarter of positive comp growth. Additional sales information can be found on Page 11 of the investor presentation.
By brand, fourth quarter American Eagle comps were up 3%, building on a 5% increase last year, and Aerie comps increased 23%, following a 34% increase in the prior year. Our stores business continued to demonstrate momentum, posting a mid-single-digit comp increase, with positive results across both brands. The investments that we've made in our stores, including talent and payroll, have delivered positive sales trends throughout the year.
Digital was also strong, posting a positive high single-digit increase in the quarter, its highest volume quarter ever. Digital penetration rose to 31% of revenue in the fourth quarter and 28% for the full year.
Overall, quality of sale metrics were healthy, particularly in stores supporting our investments in field talent and wages. On a consolidated basis, traffic and transactions increased, with store traffic positive in the quarter, outperforming the mall for both brands. Investments in store payroll and a positive response to our merchandise collections also drove an improved conversion rate. Controlled promotions led to a slight increase in the average unit retail price and transaction value.
Gross profit dollars increased to $431 million, up 1% from $425 million last year. The gross margin rate was flat at 34.6% of revenue. Lower markdowns were offset by higher delivery costs due to increased transaction counts and increased incentive expense.
SG&A expense of $288 million increased 9% from $264 million last year. As a rate to revenue, SG&A rose 160 basis points to a rate of 23.1% of sales. Investments in our brand's field talent, customer-facing store payroll, higher wages, advertising and incentives drove the majority of the increase. As well -- as we've noted, these investments have strengthened our brands and the quality of sales.
Depreciation and amortization decreased 5% to $41 million, improving 30 basis points to 3.3% as a rate to revenue.
Operating income of $101 million compared to $118 million last year and as a rate to revenue declined to 8.2% from 9.6% last year. One less week in the fourth quarter adversely affected operating income by approximately $18 million.
The effective tax rate decreased to 26.5% compared to 34.2% last year, primarily due to the impact of U.S. tax reform.
Fourth quarter earnings per share of $0.43 exceeded our guidance of $0.40 to $0.42 and compares to adjusted EPS of $0.44 last year, which excluded $0.08 of tax benefits related to U.S. tax reform.
Now a few comments and highlights regarding our annual results. Total revenue for the 52 weeks increased to 200 -- increased $240 million or 6% to a record $4 billion compared to $3.8 billion for the 53-week period last year. One less week in the year resulted in lost revenue of approximately $40 million.
Consolidated comparable sales for the year accelerated to 8%, building on a 4% increase last year. Comps were fueled by strong brand performance throughout the year. AE Brand increased 5%, and Aerie comps were up 29%. AE comps were consistently positive during 2018, and Aerie continues to grow at a fast pace, with this year marking 4 straight quarters of double-digit growth.
Gross profit dollars increased $115 million to $1.5 billion, rising 70 basis points to 36.9% as a rate to revenue. An improved markdown rate and rent leverage were partially offset by increased delivery expense due to a strong digital business and higher compensation.
SG&A of $981 million rose 11% and 110 basis points to 24.3% as a rate to revenue. Throughout the year, we made delivered investments in our brands, the customer experience and our people, which drove the dollar growth.
For the year, operating income was $339 million, increased 4% from $325 million last year. As a rate to revenue, operating income decreased to 8.4% from 8.6%. This excludes restructuring and related charges of $2 million and $22 million, respectively. Operating income was adversely affected by approximately $12 million due to operating 1 less week in the fiscal year.
Annual adjusted EPS of $1.48 increased 28% from adjusted EPS of $1.16 last year. For additional information, please refer to Pages 7 and 8 of the investor presentation.
Now turning to the balance sheet. Total ending inventories at cost increased 7% to $424 million. Inventory ended the year in line with our expectations and consistent with our demand. We ended the year with $425 million in cash and investments, up $12 million from last year. As a result of our strong free cash flow during 2018, we returned a total of $242 million to shareholders. We paid dividends of $97 million, reflecting a 10% dividend increase in the first quarter of 2018. And we repurchased 7.3 million shares for $144 million. Consistent with our guidance, capital expenditures totaled $180 million for the year. In 2019, we expect CapEx to be in the range of $200 million to $215 million. The increase in capital spending is driven primarily by increased Aerie store openings.
2018 store activity can be found on Pages 15 through 17 of the investor presentation. Total gross square footage increased 1% for the year due to additional square footage for Aerie store openings. We opened 12 new Aerie stand-alone stores and closed 6 old format stores, and we also opened 29 new Aerie side-by-side locations. For the AE Brand, we opened 16 total locations and closed 15. Our real estate priorities in 2019 are to accelerate the growth of Aerie with approximately 60 to 75 store openings, to reposition and remodel AE stores and to continue expanding globally through our franchise partnerships.
Now regarding our outlook. In the first quarter of 2019, we expect earnings per share of $0.19 to $0.21 based on comp sales in the positive low single digits.
In closing, we remain focused on driving better earnings flow-through while fueling growth in our brands. The future is bright as we look to the opportunities ahead. Our goal is to deliver consistent bottom line results while creating sustained shareholder value.
And now we'll open it up to questions.
