McCormick & Co. is experiencing its worst monthly performance in 46 years, with shares plummeting 28% in March as investors squarely rejected the spice maker's proposed $23 billion acquisition of Unilever's foods business.

The Hunt Valley, Maryland-based company announced the deal in early February, proposing to acquire Unilever's foods division in what would be one of the largest food industry mergers in recent history. The transaction, valued at approximately $23 billion including debt, would combine McCormick's seasoning portfolio with Unilever's food brands including Hellmann's, Knorr, and Magnum.

Market Context

The broader food sector has faced pressure throughout March as inflation concerns and weak consumer spending have weighed on packaged food companies. The S&P 500 Food Products Index has declined 4.2% this month, while the Dow Jones Industrial Average has remained relatively flat. McCormick's 28% decline stands out as an extreme outlier within the sector, suggesting market participants are specifically penalizing the company for the proposed transaction.

The deal announcement initially triggered a sharp selloff as analysts questioned the strategic rationale and financing structure. McCormick plans to fund the acquisition through a combination of $7 billion in new debt, $8 billion from a term loan B facility, and the remainder through equity issuance. The company has also announced it will suspend its quarterly dividend following deal closing.

Analysis

Institutional investors have led the selloff, with hedge funds and active managers expressing concern over McCormick's leverage profile post-acquisition. The combined entity would carry approximately $20 billion in net debt, pushing the company's leverage ratio well beyond its historical norms.

Analysts have grown increasingly skeptical. Jefferies downgraded McCormick to underperform from hold, citing execution risk and the challenging integration of Unilever's diverse food portfolio. Barclays flagged concerns about the company's ability to generate sufficient synergies to justify the premium valuation.

Retail sentiment has also turned negative, with short interest rising 180 basis points to 8.2% of float over the past month. Options market activity shows elevated put volume, indicating traders are positioning for further declines.

The deal faces regulatory scrutiny given the combined market share in multiple product categories. European regulators have already signaled preliminary concerns about competition in certain seasoning and condiment markets.
