Thank you, Mohammad, and good morning, everyone. As you may have seen from our press release this morning, we had a strong first quarter, and we are pleased with how well we performed against the backdrop of the persistent global COVID-19 pandemic and impact on fruit supply due to the 2 hurricanes in Guatemala in the fourth quarter of 2020.
We also dealt with rising inflationary pressures during the first quarter.
Now let's review our first quarter of 2021 results. Net sales decreased $29.7 million or 3% to $1.88 billion compared with the prior year period, with favorable exchange rates benefiting net sales by $16 million. The decrease was primarily attributable to lower net sales in our fresh and value-added and banana business segments. Adjusted gross profit increased 39% to $107 million, and our adjusted gross profit margin increased to 10% compared with 7% in the prior year period.
We benefited from increased profitability in our fresh and value-added business segment, partially offset by higher food production, procurement and distribution costs. However, I would like to point out that if you apply the adjusted gross profit margin for the fresh and value-added products segment of 8.7% to the $19 million of net sales impacted by COVID-19 in this segment, we estimate we would have delivered an additional $1.7 million in adjusted gross profit.
Adjusted operating income increased 140% to $58 million compared with the prior year period, mostly driven by increased gross profit. And adjusted net income increased 154% to $42 million compared with the prior year period. We achieved a diluted earnings per share of $0.90 compared to diluted earnings per share of $0.27 in the prior year period. Excluding nonoperational and nonrecurring items, we delivered adjusted diluted earnings per share of $0.88 compared with adjusted diluted earnings per share of $0.34 in the prior year period.
Adjusted EBITDA increased 61%, and adjusted EBITDA margin increased 300 basis points when compared with the prior year period. Let me now turn to segment results, beginning with our fresh and value-added product segment.
For the first quarter of 2021, net sales decreased $30 million or 5% compared with the prior year period. The primary drivers of the variance were lower sales volumes of melons as a result of the hurricanes in Guatemala. The impact of COVID-19 to net sales in January and February in our fresh-cut vegetable and vegetable product lines, an increase in avocado volume, which was offset by lower per unit sales price that impacted the industry, an increase in pineapple volume in most of our regions and an increase in net sales in our prepared food products line due to higher per unit sales prices.
For the quarter, adjusted gross profit in our fresh and value-added product segment increased 9% to $55 million, and adjusted gross profit margin increased 100 basis points.
During the quarter, we began to benefit from the actions we took in 2020 to optimize our operations, primarily in the following product lines: fresh-cut fruit, melon, avocados and our prepared food products.
Fresh-cut fruit margins recovered back to double digits. Rationalization in our domestic melon operations and higher per unit sale prices helped offset the damage from the hurricanes. Avocado gross profit margin doubled during the quarter and achieved the double digits. Prepared food products margins achieved the high teens.
We also pursued volume expansion during the quarter in the following product lines. Pineapple volume increased 22%, and avocado volume increased 12%. Gross profit in our non-tropical product line decreased primarily in rates as a result of damage caused by severe rainstorms to some of our farms in Chile, which resulted in a $3.1 million inventory write-off.
Our Mann Packing business was impacted by lower sales volume in our food service distribution channels, which drove higher per unit product costs.
Net sales in our banana segment decreased $9 million to $418 million while adjusted gross profit increased 93% or $23 million during the quarter, primarily driven by lower net sales in North America and the Middle East, mainly as a result of decreased sales volume, partially offset by strong demand in Asia.
Overall volume decreased 8%. Pricing increased 7%, which offset an increase in production and procurement costs due to the impact of hurricanes Eta and Iota in Guatemala as well as inflationary pressure on cost of goods sold.
Now moving to selected financial data. Selling, general and administrative expenses decreased $4 million to $49 million compared with $53 million in the prior year period. The decrease was primarily due to cost-saving initiatives in our North America region that resulted in reduced promotional expenses and lower selling and marketing costs.
The foreign currency impact at the gross profit level for the first quarter was favorable by $13 million compared with an unfavorable effect of $6 million in the prior year period. Interest expense net for the first quarter at $5 million was in line with the prior year period.
The provision for income taxes was $11 million during the quarter compared with income tax of $300,000 in the prior year period. The increase in the provision was due to -- sorry, the increase in the provision for income tax of $10.7 million is primarily due to increased earnings in certain jurisdictions.
During the quarter, we generated $47 million in cash flow from operating activities compared to $2 million in the prior year period. The increase was primarily attributable to higher net income and higher balances of accounts payable and accrued expenses, principally due to our optimization efforts associated with the working capital.
As it relates to capital spending, we invested $34 million in the first quarter compared with $17 million in the prior year period. Our investments were mainly related to our new refrigerated container ships, one of which was received during the first quarter and expansion and improvements to facilities in North America and Asia.
As of the end of the quarter, we received cash proceeds of $42.4 million in connection with our asset sales under the asset optimization program of which approximately $40 million was received in 2020. The gain during the first quarter of 2021 primarily related to a gain on the sale of a refrigerated vessel. We believe we are on track to achieve the $100 million program by the first quarter of 2022.
We paid down our long-term debt by $8 million, resulting in a total debt balance of $534 million. And based on a trailing 12 months, our total debt to adjusted EBITDA ratio stands at 2.4x.
As announced this morning in our financial results press release, our Board of Directors declared a quarterly cash dividend of $0.10 per share payable on June 11, 2021, to shareholders of record on May 19, 2021.
This concludes our financial review. We can now turn the call over for Q&A.
