Basis of Presentation

The accompanying unaudited condensed consolidated financial statements include the accounts of The Marzetti Company and our wholly-owned subsidiaries, collectively referred to as “we,” “us,” “our,” “registrant” or the “Company” and have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and SEC Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In our opinion, the interim condensed consolidated financial statements reflect all adjustments necessary for a fair presentation of the results of operations and financial position for such periods. All such adjustments reflected in the interim condensed consolidated financial statements are considered to be of a normal recurring nature. Intercompany transactions and accounts have been eliminated in consolidation. The results of operations for any interim period are not necessarily indicative of results for the full year. Accordingly, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in our 2026 Annual Report on Form 10-K. Unless otherwise noted, the term “year” and references to a particular year pertain to our fiscal year, which begins on July 1 and ends on June 30; for example, 2027 refers to fiscal 2027, which is the period from July 1, 2026 to June 30, 2027.

Property, Plant And Equipment

Property, Plant and Equipment

Property, plant and equipment are recorded at cost, except for those acquired as part of a business combination, which are recorded at fair value at the time of purchase. We use the straight-line method of computing depreciation for financial reporting purposes based on the estimated useful lives of the corresponding assets.

Earnings Per Share

Earnings per share (“EPS”) is computed based on the weighted average number of shares of common stock and common stock equivalents (restricted stock awards, restricted stock units, stock-settled stock appreciation rights and performance units) outstanding during each period. Unvested shares of restricted stock awards granted to employees are considered participating securities since employees receive nonforfeitable dividends prior to vesting and, therefore, are included in the earnings allocation in computing EPS under the two-class method. Basic EPS excludes dilution and is computed by dividing income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted EPS is computed by dividing income available to common shareholders by the diluted weighted average number of common shares outstanding during the period, which includes the dilutive potential common shares associated with nonparticipating restricted stock awards, restricted stock units, stock-settled stock appreciation rights and performance units.

The amendments should be applied either prospectively to financial statements issued for reporting periods after the effective date or retrospectively to any or all prior periods presented in the financial statements. This guidance will be effective for our annual disclosures in fiscal 2028 and for our interim-period disclosures in fiscal 2029.
