Neogen Announces Third-Quarter 2023 Results

LANSING, Mich., March 30, 2023 – Neogen Corporation (NASDAQ: NEOG) announced today the results of the third quarter ended February 28, 2023.

“The breadth of our product portfolio contributed to both legacy Neogen segments delivering quarterly core growth in a weaker end market environment,” said John Adent, Neogen’s President and Chief Executive Officer. “The performance of the former 3M Food Safety Division was mixed, with market demand offset by the production backlog situation at our transition manufacturing partner, where we believe significant engagement from senior levels of their organization and a modified reporting structure provide a path to successful resolution. Despite navigating what we expect to be a transitory issue, market reception to the merger has been positive and we are focused on positioning the combined business for long-term success. We have a growing pipeline of targeted synergy opportunities and recently opened our new distribution center in Mount Sterling, Kentucky, which will be a single, more-efficient point of distribution in the U.S. for the entire company. We also continued to add critical personnel, with additions to our back-office and ancillary teams, who will play a key role in supporting our larger enterprise.”

Adent continued, “We are excited about the opportunities we have ahead of us as the clear, pure-play leader in the food security market, with a portfolio consisting of over 95% consumable products. While our market is not immune to economic slowdowns, it historically has been resilient and has what we believe are long-term, secular tailwinds – heightened pathogen awareness, the growing prevalence of food allergies and increasingly health-conscious consumers who demand to know what’s in their food. There is clearly work that remains ahead of us, but I’m proud of the progress we’ve made and the efforts of our team members globally as we integrate a high-quality business and lay the groundwork for One Neogen moving forward.”

Financial and Business Highlights

Revenues for the third quarter were $218.3 million, an increase of 70.2% compared to $128.2 million in the prior year. Core revenue growth, which excludes the impacts of foreign currency translation and acquisitions completed in the last 12 months, was 4.0%, while acquisitions contributed 68.1%. Foreign currency was a headwind of 1.9%. International sales, which accounted for 49.6% of total company revenue, grew 8.9% on a core basis.

The third quarter marked the 123rd of the past 129 quarters that Neogen reported revenue increases compared to the same quarter in the prior year.

Net income for the third quarter was $8.2 million, or $0.04 per diluted share, compared to $5.4 million, or $0.05 per diluted share, in the prior-year period. The increase in net income was driven primarily by incremental revenues from the former 3M Food Safety Division, which generated margins higher than the legacy company average margin. This increase was partially offset by transaction and integration costs, interest expense and the amortization of acquisition-related intangibles, all related to the recently completed merger with the former 3M Food Safety Division. Adjusted Net Income was $26.5 million, or $0.12 per diluted share, compared to $16.2 million, or $0.15 per diluted share, in the prior-year period. Higher Adjusted EBITDA drove the increase in Adjusted Net Income, more than offsetting the increase in interest expense. On a per-share basis, Adjusted Net Income was lower by $0.03 in the third quarter compared to the prior-year period, a result of the increase in shares outstanding related to the 3M Food Safety transaction.

Gross margin, expressed as a percentage of sales, was 49.5% in the third quarter of fiscal 2023. This compares to a gross margin of 44.8% in the same quarter a year ago, with the increase primarily due to the higher gross margins generated by the incremental revenues from the former 3M Food Safety Division.

Third-quarter Adjusted EBITDA was $51.3 million, representing an Adjusted EBITDA Margin of 23.5%, compared to $24.9 million and a margin of 19.4% in the prior year. The margin expansion was primarily driven by the increase in gross margin, which more than offset expenses added during the quarter to accommodate the expanded scale of the business.

Food Safety Segment

Revenues for the Food Safety segment were $151.5 million in the third quarter, an increase of 141.5% compared to $62.8 million in the prior year, consisting of 5.8% core growth, 139.1% from acquisitions, and a foreign currency headwind of 3.4%. The core growth was led by the Culture Media & Other category, which benefited from a large order from a vaccine manufacturer. In the Bacterial & General Sanitation product category, a solid increase in sales of Soleris® spoilage detection products was partially offset by a decline in sales of AccuPoint® general sanitation products, due in part to supply challenges, resulting in modest core growth. The Natural Toxins, Allergens, & Drug Residues category experienced a slight core revenue decline, with increases in sales of aflatoxin test kits offset by a decline in sales of allergen test kits, due in part to supply challenges, and the discontinuation of a drug residue product line consisting of test kits for international dairy markets.

Animal Safety Segment

Revenues for the Animal Safety segment were $66.7 million in the third quarter, an increase of 1.9%, compared to $65.5 million in the prior year’s third quarter, consisting of 2.2% core growth and a foreign currency headwind of 0.3%. The core growth was led by the Company’s portfolio of biosecurity products, driven largely by insect control share gains in the animal protein market. The core growth in biosecurity products was partially offset by core revenue declines in Veterinary Instruments & Disposables, due to a difficult comparison to new business won in the prior year, and in Animal Care & Other, due to lower sales of antibiotics and vitamin injectables.

The Company’s worldwide genomics business performed well in the quarter, with core growth of 7.7%, led by volume increases in the global beef markets, partially offset by declines in testing in China caused by a continuation of COVID-related lab closures.

Liquidity and Capital Resources

As of February 28, 2023, the Company had total cash and investments of $183.2 million and total outstanding debt of $900.0 million, which reflects a repayment of $40.0 million in the quarter, as well as committed borrowing headroom of $150.0 million.

Non-GAAP Financial Measures

This press release includes certain non-GAAP financial measures, which management believes are useful to investors, securities analysts and other interested parties. Management uses Adjusted EBITDA as a key profitability measure. This is a non-GAAP measure that represents EBITDA before certain items that impact comparison of the performance of our business either period-over-period or with other businesses. Adjusted EBITDA Margin is Adjusted EBITDA for a particular period expressed as a percentage of revenues for that period.

Management uses Adjusted Net Income as an additional measure of profitability. Adjusted Net Income is a non-GAAP measure that represents net income before certain items that impact comparison of the performance of our business, either period-over-period or with other businesses.

Core revenue growth is a non-GAAP measure that represents net sales for the period excluding the impacts of foreign currency translation rates and the first-year impacts of acquisitions and disposals, where applicable. We present core revenue growth because it allows for a meaningful comparison of year-over-year performance without the volatility caused by foreign currency gains or losses, or the incomparability that would be caused by the impact of an acquisition or disposal.

These non-GAAP financial measures should be considered only as supplemental to, and not as superior to, financial measures prepared in accordance with GAAP. Please see below for a reconciliation of historical non-GAAP financial measures to the most directly comparable financial measures prepared in accordance with GAAP.
