Thank you, Jack. Our comments may contain certain forward-looking statements regarding possible events, including expectations that are not considered guarantees of future performance.

We are very happy with the financial results for the first quarter. Despite the weather challenges we experienced in our markets, overall, revenues were up 10%, and EBITDA grew by $1.6 million compared to the first quarter last year. We generated a bottom line profit of $1 million or $0.17 per diluted share, which was an $800,000 improvement over the first quarter last year. The increase in revenues and profit compared to the first quarter last year is primarily due to growth of our appliance replacement programs and recognizing $1 million in carbon offset revenues.
Our recycling segment continues to generate solid financial results. Recycling revenues of $12.1 million were up $3.8 million compared to the first quarter last year. The growth was primarily due to a 72% increase in appliance replacement program volumes, partially offset by a 16% decline in recycling-only volumes. Mark will talk more about our recycling division later in the call.
Byproduct revenues of $4.8 million were up $800,000 compared to the first quarter last year. The increase is the result of recognizing $1 million in carbon offset revenues. Of the $1 million, $700,000 was at ARCA, and $300,000 was at AAP. We expect to generate another $500,000 in carbon offset revenues during the latter part of 2014.
Revenues at AAP, which are also reported on the income statement as byproduct revenues, were $2.8 million in the first quarter, up $200,000 compared with last year. The increase was due primarily to $300,000 in carbon offset revenues, and partially offset by a 6% decline in recyclable appliances. Our recycling business, including AAP, generated an operating profit of $2.1 million in the first quarter, up $1.3 million compared with last year. Within that increase, AAP improved its operating profit by $400,000 due to a combination of the carbon offset sales previously mentioned, and a 65% reduction in the acquisition costs of certain recyclable appliances.
ApplianceSmart, our retail division, improved its operating profit despite the tough winter weather that negatively impacted top line sales. ApplianceSmart sales were down $1.5 million compared with the first quarter last year. The decrease in revenue was also a result of a 6% decline in same-store sales we believe to be weather-related and operating one less store. ApplianceSmart generated an operating profit of $100,000 in the first quarter, an improvement of $300,000 compared with last year. The improvement was due primarily to a more favorable sales mix and lower occupancy and operating expenses.
I will now turn the call over to Brad who will talk more about ApplianceSmart.
