Basic net loss per Class A common share has been calculated by dividing net loss for the period, adjusted for net loss attributable to non-controlling interests, by the weighted average number of Class A common shares outstanding during the period. In periods in which the Company reports a net loss attributable to Maravai LifeSciences Holdings, Inc., diluted net loss per Class A common share attributable to the Company is the same as basic net loss per Class A common share attributable to the Company, since dilutive equity instruments are not assumed to have been issued if their effect is anti-dilutive. The Company reported a net loss attributable to Maravai LifeSciences Holdings, Inc. during the three and six months ended June 30, 2026 and 2025.

Shares underlying contingently issuable awards that have not met the necessary conditions as of the end of a reporting period are not included in the calculation of diluted net loss per Class A common share attributable to the Company for that period. The Company had contingently issuable performance stock units outstanding that did not meet the market conditions as of June 30, 2026 and 2025 and, therefore, were excluded from the calculation of diluted net loss per Class A common share attributable to the Company. The maximum number of potentially dilutive shares that could be issued upon vesting for such awards was 3.3 million as of June 30, 2026 and 3.3 million as of June 30, 2025. These share amounts were excluded from the potentially dilutive securities in the table above.
