Minneapolis, Minnesota - May 10, 2023 - SunOpta Inc. ("SunOpta" or the "Company") (Nasdaq:STKL) (TSX:SOY), a U.S.-based global pioneer fueling the future of sustainable, plant-based and fruit-based foods and beverages, today announced financial results for the first quarter ended April 1, 2023. 

All amounts are expressed in U.S. dollars and results are reported in accordance with U.S. GAAP, except where specifically noted.

First Quarter 2023 highlights:

• Excluding the divested sunflower business, total company revenues of $223.9 million were up 0.4% from the prior year period. Plant-Based Foods and Beverages revenues increased by 9.3%, partially offset by a 9.7% decline in Fruit-Based Foods and Beverages revenues. 

• The Plant-Based Foods and Beverages segment revenue growth was led by a 25% increase in plant-based milk products, partially offset by declines in lower margin broth and ingredients.

• Gross profit margin was up 80 basis points on a reported basis and improved 320 basis points to 15.2% adjusted for startup costs related to the new Texas plant.

• Earnings from continuing operations were $1.4 million compared to $1.0 million in the prior year period.

• Adjusted earnings¹ attributable to common shareholders were $6.0 million or $0.05 per diluted common share, compared to adjusted earnings of $0.9 million or $0.01 per diluted common share in the prior year period. 

• Adjusted EBITDA¹ of $23.6 million, was up 50.5% versus $15.7 million. As a percentage of revenue, adjusted EBITDA was 10.5% compared to 6.5% in the prior year period.   

"We delivered another quarter of significant increase in profitability as margin-focused portfolio optimization and revenue expansion initiatives continue to flow through to profit," said Joe Ennen, Chief Executive Officer.  "We continue to have strong momentum in our businesses by leveraging our value proposition of operating expertise, available capacity and strong R&D and innovation capabilities.  Plant-based milk products revenue increased 25% year-over-year including an 89% increase in oat.  This growth was broad-based from a customer perspective and all go-to-market approaches were positive.  Strong plant-based operational execution continues, as evidenced by a gross profit margin of 20%, excluding start-up costs.  To that point, production start-up at our new plant in Texas continues to be on schedule, setting the stage for strong second half growth.  We remain well positioned competitively, confident in our outlook for 2023, and steadfast in our focus on Fueling the Future of Food."

First Quarter 2023 Results

Excluding the divested sunflower business, total company revenues of $223.9 million were up 0.4% from the prior year period. Plant-Based Foods and Beverages revenues increased by 9.3%, partially offset by a 9.7% decline in Fruit-Based Foods and Beverages revenues.

The Plant-Based Foods and Beverages segment generated revenues of $129.4 million, a decrease of 4.5% compared to $135.5 million in the first quarter of 2022.  Excluding the impact of our sunflower business, which was divested in October, revenue from Plant-Based Foods and Beverages increased 9.3%, with pricing accounting for 10.2% of the growth, partially offset by an unfavorable volume/mix impact of 0.9%.  Volume reflected continued penetration and strength in oat-based offerings, coconut and soy milks, and teas, slightly more than offset by declines in broth and ingredients. 

The Fruit-Based Foods and Beverages segment generated revenues of $94.5 million, a decrease of 9.7% compared to $104.7 million in the first quarter of 2022. Pricing increased 1.3% reflecting actions to offset inflationary pressures on fruit inventories and operating expenses, while volume/mix declined 11.0% driven by lower demand for frozen fruit, the impact of one-time incremental volumes from a frozen fruit customer in 2022 that did not recur, partially offset by strong demand and higher pricing for fruit snacks, as well as incremental sales from our line of smoothie bowls.

Gross profit of $28.2 million for the first quarter was relatively flat compared to the prior year period.  As a percentage of revenues, gross profit margin was 12.6% compared to 11.8% in the first quarter of 2022, an increase of 80 basis points, as reported. Gross profit in the Plant-Based Foods and Beverages segment was essentially flat at $20.2 million, while gross margin increased 60 basis points to 15.6%. Excluding the impact of start-up costs related to the new plant in Midlothian, Texas, adjusted gross margin for the Plant-Based Foods and Beverages segment was 20.0% in the first quarter of 2023, compared to 15.3% in the first quarter of 2022.  The 470-basis point increase in adjusted gross margin reflected an approximately 170 basis point improvement following the sale of our lower-margin sunflower commodity business, impacts from pricing actions taken in 2022 and the positive gross margin impact of a mix shift in our plant-based ingredient operations with increased internal use of oat base to support our beverage business and lower external sales. Gross profit in the Fruit-Based Foods and Beverages segment of $8.0 million, was flat compared to the prior year period, while gross margin increased 80 basis points to 8.5% mainly driven by strong revenue growth in fruit snacks, partially offset by a higher mix of lower margin bulk frozen fruit sales.

Segment operating income¹ was $2.5 million, or 1.1% of revenue in the first quarter of 2023, compared to segment operating income of $4.0 million, or 1.7% of revenues in the first quarter of 2022. The decrease in segment operating income was driven by increased SG&A due to higher stock-based incentive compensation expense and business development costs partially offset by a $1.7 million foreign exchange benefit.

Earnings attributable to common shareholders for the first quarter of 2023 were $0.7 million, or $0.01 per diluted common share, compared to income of $3.8 million, or $0.04 per diluted common share during the first quarter of 2022. 

Adjusted earnings¹ in the first quarter of 2023 were $6.0 million or $0.05 per common share, compared to adjusted earnings of $0.9 million or $0.01 per common share in the first quarter of 2022.

Adjusted EBITDA¹ was $23.6 million or 10.5% of revenue in the first quarter of 2023, compared to $15.7 million or 6.5% of revenue in the first quarter of 2022.

Please refer to the discussion and table below under "Non-GAAP Measures".

¹ See discussion of non-GAAP measures

² The Company has included certain forward-looking statements about future financial performance that include non-GAAP financial measures, including Adjusted EBITDA. These non-GAAP financial measures are derived by excluding certain amounts, expenses or income, from the corresponding financial measures determined in accordance with GAAP. The determination of the amounts that are excluded from these non-GAAP financial measures is a matter of management judgment and depends upon, among other factors, the nature of the underlying expense or income amounts recognized in a given period. We are unable to present a quantitative reconciliation of the aforementioned forward-looking non-GAAP financial measures to their most directly comparable forward-looking GAAP financial measures because management cannot reliably predict all of the necessary components of such GAAP measures. Historically, management has excluded the following items from certain of these non-GAAP measures, and such items may also be excluded in future periods and could be significant amounts.

• Expenses related to the acquisition or divestiture of businesses or assets, including business development costs, impairment of assets, integration costs, severance, retention costs and transaction costs;
• Start-up costs of new facilities and equipment;
• Charges associated with restructuring and cost saving initiatives, including but not limited to asset impairments, accelerated depreciation, severance costs and lease abandonment charges;
• Asset impairment charges and facility closure costs;
• Legal settlements or awards; and
• The tax effect of the above items.

Non-GAAP Measures

In addition to reporting financial results in accordance with U.S. GAAP, the Company provides additional information about its operating results regarding segment operating income, adjusted earnings and adjusted earnings before interest, taxes, depreciation and amortization ("adjusted EBITDA"), which are not measures in accordance with U.S. GAAP. The Company believes that segment operating income, adjusted earnings and adjusted EBITDA assist investors in comparing performance across reporting periods on a consistent basis by excluding items that management believes are not indicative of its operating performance. The non-GAAP measures of segment operating income, adjusted earnings and adjusted EBITDA should not be considered in isolation or as a substitute for performance measures calculated in accordance with U.S. GAAP.

In order to evaluate its results of operations, the Company uses certain other non-GAAP measures that it believes enhance an investor's ability to derive meaningful period-over-period comparisons and trends from the results of operations. In particular, the Company excludes specific items from its reported results that due to their nature or size, it does not expect to occur as part of its normal business on a regular basis. These items are identified in the tables below. These non-GAAP measures are presented solely to allow investors to more fully assess the Company's results of operations and should not be considered in isolation of, or as substitutes for, an analysis of the Company's results as reported under U.S. GAAP.

Adjusted Earnings

When assessing its financial performance, the Company uses an internal measure that excludes charges and gains that it believes are not reflective of normal operations. This information is provided to allow investors to make meaningful comparisons of the Company's operating performance between periods and to view the Company's business from the same perspective as the Company's management. Adjusted earnings and adjusted earnings per diluted share should not be considered in isolation or as a substitute for performance measures calculated in accordance with U.S. GAAP.

The following is a tabular presentation of adjusted earnings and adjusted earnings per diluted share, including a reconciliation from earnings from continuing operations, which the Company believes to be the most directly comparable U.S. GAAP financial measure. 

(a) For the first quarter of 2023, start-up costs mainly related to the ramp-up of production at our new plant-based beverage facility in Midlothian, Texas, which were recorded in cost of goods sold ($5.8 million) and SG&A expenses ($0.6 million). For the first quarter of 2022, start-up costs mainly related to the hiring and training of new employees for the Midlothian facility, together with the integration of the Dream and West Life brands, which were recorded in cost of goods sold and SG&A expenses.

(b) Represents third-party costs associated with business development activities, including costs related to the evaluation, execution, and integration of external acquisitions and divestitures, internal expansion projects, and other strategic initiatives. For the first quarters of 2023 and 2022, these costs were recorded in SG&A expenses.

(c) Reflects the tax effect of the preceding adjustments to earnings calculated based on the statutory tax rates applicable in the tax jurisdiction of the underlying adjustment.

Segment Operating Income and Adjusted EBITDA

The Company defines segment operating income as earnings from continuing operations before income taxes, interest expense and other income/expense items, and adjusted EBITDA as segment operating income plus depreciation, amortization, stock-based compensation, and other unusual items that affect the comparability of operating performance as identified above in the determination of adjusted earnings. The following is a tabular presentation of segment operating income and adjusted EBITDA, including a reconciliation from earnings from continuing operations, which the Company believes to be the most directly comparable U.S. GAAP financial measure.

(a) For the first quarter of 2023, start-up costs mainly related to the ramp-up of production at our new plant-based beverage facility in Midlothian, Texas, which were recorded in cost of goods sold ($5.8 million) and SG&A expenses ($0.6 million). For the first quarter of 2022, start-up costs mainly related to the hiring and training of new employees for the Midlothian facility, together with the integration of the Dream and West Life brands, which were recorded in cost of goods sold and SG&A expenses.

(b) For the first quarters of 2023 and 2022, business development costs were recorded in SG&A expenses.

Adjusted Revenues

The following table presents adjusted revenues by segment and consolidated, together with a reconciliation from reported revenues. Adjusted revenues excludes revenues of the Company's former sunflower business, which was divested in October 2022.
