BOSTON BEER CO INC

The Company calculates net (loss) income per share using the two-class method, which requires the Company to allocate net (loss) income to its Class A Common Shares, Class B Common Shares and unvested share-based payment awards that participate in dividends with common stock, in the calculation of net (loss) income per share.

The Class A Common Stock has no voting rights, except (1) as required by law, (2) for the election of Class A Directors, and (3) that the approval of the holders of the Class A Common Stock is required for (a) certain future authorizations or issuances of additional securities which have rights senior to Class A Common Stock, (b) certain alterations of rights or terms of the Class A or Class B Common Stock as set forth in the Articles of Organization of the Company, (c) other amendments of the Articles of Organization of the Company, (d) certain mergers or consolidations with, or acquisitions of, other entities, and (e) sales or dispositions of any significant portion of the Company’s assets.

The Class B Common Stock has full voting rights, including the right to (1) elect a majority of the members of the Company’s Board of Directors and (2) approve all (a) amendments to the Company’s Articles of Organization, (b) mergers or consolidations with, or acquisitions of, other entities, (c) sales or dispositions of any significant portion of the Company’s assets, and (d) equity-based and other executive compensation and other significant corporate matters. The Company’s Class B Common Stock is not listed for trading. Each share of the Class B Common Stock is freely convertible into one share of Class A Common Stock, upon request of the respective Class B holder, and participates equally in dividends.

The Company’s unvested share-based payment awards include unvested shares (1) issued under the Company’s investment share program, which permits employees who have been with the Company for at leastone year to purchase shares of Class A Common Stock and to purchase those shares at a discount ranging from 20% to 40% below market value based on years of employment starting aftertwo years of employment, and (2) awarded as restricted stock units at the discretion of the Company’s Board of Directors. The investment shares vest over five years in equal number of shares and the restricted stock units generally vest over four years in equal number of shares. If a dividend is declared, the unvested shares would participate equally. See Note M for a discussion of the current year unvested stock awards and issuances.

Included in the computation of net (loss) income per diluted common share are dilutive outstanding stock options and restricted stock that are vested or expected to vest, to the extent such awards are dilutive. At its discretion, the Board of Directors grants stock options and restricted stock units to senior management and certain key employees. The terms of the employee stock options are determined by the Board of Directors at the time of grant. To date, stock options granted to employees vest over various service periods and/or based on the attainment of certain performance criteria and generally expire after ten years. The restricted stock units generally vest over four years in equal number of shares. Each restricted stock unit represents an unfunded and unsecured right to receive one share of Class A Stock upon satisfaction of the vesting criteria. The unvested shares participate equally in dividends, if declared, and are forfeitable. The Company also grants stock options and restricted stock units to its non-employee directors upon election or re-election to the Board of Directors. The number of option shares granted to non-employee directors is calculated based on a defined formula and these stock options vest immediately upon grant and expire after ten years. The restricted stock units granted to non-employee directors vestone year post grant date.

Net (Loss) Income per Common Share - Basic

The following table sets forth the computation of basic net (loss) income per share using the two-class method:

Net (Loss) Income per Common Share - Diluted

The Company calculates diluted net (loss) income per share for common stock using the more dilutive of (1) the treasury stock method, or (2) the two-class method, which assumes the participating securities are not exercised.

For the thirteen weeks ended March 28, 2026, the Company was in a net loss position. As a result, all potential common shares were anti‑dilutive, and diluted net loss per common share is the same as basic net loss per common share. Accordingly, the computation of diluted net loss per common share reflects the same allocation of net loss and the same weighted‑average common shares outstanding as those used in the calculation of basic net loss per common share.

For the thirteen weeks ended March 29, 2025, the Company reported net income. Diluted net income per common share reflects the allocation of earnings to participating securities under the two‑class method and the inclusion of dilutive share‑based awards in the diluted weighted‑average common shares outstanding.

The following table sets forth the computation of diluted net (loss) income per common share for the periods presented:

For the thirteen weeks ended March 28, 2026, in accordance with the two-class method, weighted‑average stock options to purchase 251,438 shares were outstanding but not included in computing dilutive income per common share because the net loss position of the Company made them anti‑dilutive.

For the thirteen weeks ended March 29, 2025, in accordance with the two-class method, weighted-average stock options to purchase 162,934 shares were outstanding but not included in computing dilutive income per common share because their effects were anti-dilutive.

Additionally, performance-based stock options to purchase 40,103 shares of Class A Common Stock and 85,209 performance-based stock awards were outstanding as of March 29, 2025, but not included in computing diluted income per common share because the performance criteria were not met as of the end of the reporting period.

I. Commitments and Contingencies

Contractual Obligations

As of March 28, 2026, projected cash outflows under non-cancellable contractual obligations are as follows:

The Company expects to pay $152.8 million of these obligations in the remainder of fiscal 2026, $22.7 million in fiscal 2027, $12.6 million in fiscal 2028, and $38.6 million in fiscal 2029 and thereafter. The commitment amounts exclude any impact related to the tariff programs announcement by the U.S. government.

Litigation

The Company is party to legal proceedings and claims, including class action claims, where significant damages are asserted against it. Given the inherent uncertainty of litigation, it is possible that the Company could incur liabilities as a consequence of these claims, which may or may not have a material adverse effect on the Company’s financial condition or the results of its operations. The Company accrues loss contingencies if, in the opinion of management and its legal counsel, the risk of loss is probable and the loss can be estimated. Material pending legal proceedings are discussed below.

Supplier Dispute. As previously reported, including in the Company’s Annual Report on Form 10-K for the year ended December 27, 2025, on December 31, 2022, Ardagh Metal Packaging USA Corp. (“Ardagh”) filed an action against the Company alleging, among other things, that the Company had failed or would fail to purchase contractual minimum volumes of certain aluminum beverage can containers in 2021 to 2026. The trial on the dispute commenced on March 23, 2026 and on April 6, 2026, the jury returned a verdict awarding damages to Ardagh. As a result of the verdict, during the first quarter of 2026 the Company recorded a non-recurring pre-tax litigation expense of $175.5 million and related pre-judgement interest expense of $36.5 million. The pre-judgement interest has not yet been determined and potential outcomes range between zero and $36.5 million. In addition, the Company recorded $4.0 million of legal fees within general and administrative expenses. The total pre‑tax impact of these items was $216.0 million. As of March 29, 2026, the $216.0 million litigation-related liability was included in accrued expenses and other current liabilities on the accompanying condensed consolidated balance sheet. The recorded amounts are within the range previously disclosed by the Company of between zero and $300 million, plus interest if assessed.

The Company denies that it breached the terms of the parties’ contract and intends to pursue all available post‑trial motions and appellate remedies. As of the filing date of this Quarterly Report, a final judgment has not been entered and post‑trial motions have not yet been filed. The Company cannot estimate when or if damages or interest will ultimately be paid or when this matter will ultimately be resolved.

J. Income Taxes

The following table presents the Company’s effective income tax rates for the thirteen weeks ended March 28, 2026 and March 29, 2025:

For the thirteen weeks ended March 28, 2026, the Company recorded an income tax benefit, resulting in an effective tax rate of 23.1%, compared to an income tax provision with an effective tax rate of 31.9% for the thirteen weeks ended March 29, 2025. The change in the effective tax rate period over period was primarily driven by a pre‑tax loss in the first quarter of 2026 compared to pre‑tax income in the first quarter of 2025, as well as changes in the impact of non‑deductible expenses.

As of both March 28, 2026 and December 27, 2025, the Company had approximately $0.5 million of unrecognized income tax benefits.

The Company’s practice is to classify interest and penalties related to income tax matters in income tax expense. As of March 28, 2026 and December 27, 2025, the Company had approximately $0.1 million accrued for interest and penalties recorded in other liabilities.

The Company's federal income tax returns remain subject to examination forthree years. The Company’s state income tax returns remain subject to examination forthree orfour years depending on the state’s statute of limitations. The Company is currently under one state income tax audit as of March 28, 2026.

K. Line of Credit

In December 2022, the Company amended its credit facility in place that provides for a $150.0 million revolving line of credit to extend the maturity date to December 16, 2027. Under the terms of the amended agreement, the Company may elect an interest rate for borrowings under the credit facility based on the applicable secured overnight financing rate ("SOFR") plus 1.1%. As of March 28, 2026, no borrowings were outstanding. As of March 28, 2026 and December 27, 2025, the Company was not in violation of any of its financial covenants to the lender under the credit facility and the unused balance of $150.0 million on the line of credit was available to the Company for future borrowings.

L. Fair Value Measures

The Company defines fair value as the price that would be received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).

•

Level 1 — Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

•

Level 2 — Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. If the asset or liability has a specified (contractual) term, a Level 2 input must be observable for substantially the full term of the asset or liability.

•

Level 3 — Level 3 inputs are unobservable inputs for the asset or liability in which there is little, if any, market activity for the asset or liability at the measurement date.

The Company’s cash and cash equivalents are held in money market funds. These money market funds are measured at fair value on a recurring basis and are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices. The money market funds are invested substantially in United States Treasury and government securities. The Company does not adjust the quoted market price for such financial instruments. Cash, accounts receivable, and accounts payable are carried at their cost, which approximates fair value, because of their short-term nature. Other accrued expenses and liabilities, including accrued litigation‑related loss contingencies, accrued interest, and accrued legal costs, are measured at accrued amounts in accordance with their applicable accounting guidance and are not required to be recorded at fair value; accordingly, these amounts are excluded from the Company’s fair value measurements and related hierarchy disclosures.

As of March 28, 2026 and December 27, 2025, the Company had money market funds with a “Triple A” rated money market fund. The Company considers the “Triple A” rated money market fund to be a large, highly-rated investment-grade institution. As of March 28, 2026 and December 27, 2025, the Company’s cash and cash equivalents balance was $164.1 million and $223.4 million, respectively, including money market funds amounting to $157.8 million and $216.7 million, respectively.

Non-Recurring Fair Value Measurement

The fair value as of the issuance date of the Company's note receivable is classified within Level 2 of the fair value hierarchy as the fair value was partially derived from publicly quoted inputs of market interest rates for a loan of similar terms, provisions, and maturity. See Note G for further discussion on the note receivable.

M. Common Stock and Stock-Based Compensation

Additionally, on March 1, 2026, employees elected to purchase a combined 11,083 shares under the Company’s investment share program. The weighted average fair value of the restricted stock units and investment shares, which are sold to employees at discount under its investment share program, was $226.78 and $132.59 per share, respectively.

Weighted average assumptions used to estimate fair values of shares purchased under the Company's investment share program are as follows:

The following table provides information regarding stock-based compensation expense included in operating expenses in the accompanying condensed consolidated statements of comprehensive operations:

Stock Repurchases

In 1998, the Company began a share repurchase program. Under this program, the Company's Board of Directors has authorized the repurchase of the Company's Class A Stock. On October 2, 2024, the Board of Directors authorized an increase in the aggregate expenditure limit for the Company’s stock repurchase program by $400.0 million, increasing the limit from $1.2 billion to $1.6 billion. The Board of Directors did not specify a date upon which the total authorization would expire and, in the future, can further increase the authorized amount. Share repurchases under this program for the periods included herein were effected through open market transactions.

During the thirteen weeks ended March 28, 2026, the Company repurchased and subsequently retired 107,380 shares of its Class A Common Stock for an aggregate purchase price of $23.8 million. As of March 28, 2026, the Company had repurchased a cumulative total of approximately 15.9 million shares of its Class A Common Stock for an aggregate purchase price of approximately $1.395 billion and had approximately $205 million remaining on the $1.6 billion stock repurchase expenditure limit set by the Board of Directors.

N. Segment Reporting

Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision maker ("CODM"), or decision making group, in deciding how to allocate resources in assessing performance. The Company hasone operating segment andone reportable segment that produces and sells alcohol beverages under various brands. All brands are predominantly beverages that are manufactured using similar production processes, have comparable alcohol content, generally fall under the same regulatory environment, and are sold to the same types of customers in similar size quantities at similar price points, with similar profit margins, and through the same channels of distribution. The Company’s CODM is the chief executive officer.

The accounting policies of the segment are the same as those described in the summary of significant accounting policies. The CODM assesses performance for the segment based on net (loss) income, which is reported on the income statement as consolidated net (loss) income. The measure of segment assets is reported on the balance sheet as total consolidated assets.

The table below summarizes the Company’s measures of segment net (loss) income that the CODM considered in determining how to allocate resources and assess segment performance for the thirteen weeks ended March 28, 2026, and March 29, 2025:
