Thirteen Weeks Ended April 30, 2022 and May 1, 2021
Net Sales. Net sales decreased $77.2 million, or 27.0%, to $208.2 million in the first quarter of 2022 from $285.4 million in the first quarter of 2021. The decrease in sales was due to a 29.2% decrease in comparable store sales, partially offset by a $5.6 million increase from net store opening and closing activity. The decrease in comparable store sales was due to outsized sales in the first quarter of last year driven by government stimulus payments, combined with inflationary pressures in the first quarter of this year that are particularly impactful to our core customers.
Cost of sales (exclusive of depreciation). Cost of sales (exclusive of depreciation) decreased $36.8 million, or 22.5%, to $127.0 million in the first quarter of 2022 from $163.8 million in the first quarter of 2021. Cost of sales as a percentage of sales increased to 61.0% in the first quarter of 2022 from 57.4% in the first quarter of 2021, due primarily to an increase in markdowns, as unusually low markdowns were taken in the first quarter of last year due to the outsized stimulus-driven demand. Compared to the first quarter of 2021, cost of sales increased 360 basis points, due to a decrease of 280 basis points in the core merchandise margin (initial mark-up, net of markdowns) and increases of 50 basis points and 30 basis points in freight costs and shrink expense, respectively, driven by the deleveraging effect of lower sales.
Selling, General and Administrative Expenses. Selling, general and administrative expenses decreased $6.9 million, or 8.8%, to $71.0 million in the first quarter of 2022 from $77.9 million in the first quarter of 2021. The decrease was due primarily to $5.9 million decrease in incentive based compensation as a result of unfavorable operating results in relation to budget this year (compared to overperformance in the first quarter last year) as well as increased costs last year related to the recognition of cash-settled stock awards based on the stock price. Also contributing to the lower expense were decreases in certain variable costs such as credit card processing fees and store supplies, partially offset by growth-related increases in costs for opening and operating more stores. As a percentage of sales, selling, general and administrative expenses increased to 34.1% in the first quarter of 2022 from 27.3% in the first quarter of 2021.
Depreciation. Depreciation expense increased $0.7 million, or 15.9%, to $5.4 million in the first quarter of 2022 from $4.7 million in the first quarter of 2021.
Gain on sale-leaseback. In the first quarter of 2022, we completed a sale-leaseback transaction for our distribution center in Darlington, South Carolina that resulted in a $34.9 million gain.
Income Tax Expense. Income tax expense was $9.4 million in the first quarter of 2022 compared to $8.1 million in the first quarter of 2021. Our effective tax rate for the first quarter of this year was 23.7% compared to 20.7% in the first quarter of last year, with the difference attributable to a favorable tax impact of restricted stock vestings in the prior year.
Net Income. Net income was $30.2 million in the first quarter of 2022 compared to $30.9 million in the first quarter of 2021 due to the factors discussed above.
Liquidity and Capital Resources
Capital Allocation
Our capital allocation strategy is to prioritize investments in opportunities to profitably grow our business and maintain current operations, then to return excess cash to shareholders through our repurchase programs. Our quarter-end cash and cash equivalents balance was $61.7 million compared to $131.3 million at the end of the first quarter last year. Until required for other purposes, we maintain cash and cash equivalents in deposit or money market accounts.
Our principal sources of liquidity consist of: (i) cash and cash equivalents on hand; (ii) short-term trade credit arising from customary payment terms and trade practices with our vendors; (iii) cash generated from operations on an ongoing basis; and (iv) a revolving credit facility with a $75.0 million credit commitment.
In addition, in April 2022, we completed a sale-leaseback transaction of our distribution center in Darlington, South Carolina, for net proceeds of $45.5 million.
Inventory
Our quarter-end inventory balance was $129.7 million, compared with $101.8 million at the end of the first quarter last year. The increase was primarily due to depleted inventory levels at the end of the first quarter last year driven by outsized sales,
