Earnings (Loss) Per Share

9 Months Ended

Sep. 30, 2025

The following table sets forth the computation of basic and diluted weighted average common shares outstanding and associated net income (loss) per common share attributable to Bruker Corporation common shareholders (in millions, except per share amounts):


	Three Months Ended September 30,					Nine Months Ended September 30,
	2025			2024		2025			2024
Net (loss) income attributable to Bruker Corporation	$	(59.6	)	$	40.9	$	(34.6	)	$	99.4
Dividends on Series A Mandatory Convertible Preferred Stock		2.8		—			2.8		—
Net (loss) income attributable to Burker Corporation common shareholders	$	(62.4	)	$	40.9	$	(37.4	)	$	99.4

Weighted average common shares outstanding:
Weighted average common shares outstanding - basic		151.8			151.5		151.7			148.1
Effect of dilutive securities:
Stock options, restricted stock units, and employee stock purchase plan		—			0.5		—			0.6
Series A Mandatory Convertible Preferred Stock		—			—		—			—
Weighted average common shares outstanding - diluted		151.8			152.0		151.7			148.7
Net (loss) income per common share attributable to Bruker Corporation common shareholders:
Basic	$	(0.41	)	$	0.27	$	(0.25	)	$	0.67
Diluted	$	(0.41	)	$	0.27	$	(0.25	)	$	0.67

The Company computes basic net income (loss) per common share based on the net income (loss) attributable to Bruker Corporation common shareholders divided by the weighted average number of common shares outstanding during the period. The Company computes diluted net income (loss) per common share based on the net income (loss) attributable to Bruker Corporation common shareholders divided by the weighted average number of common shares outstanding plus potentially dilutive common shares outstanding during the period.

Potentially dilutive common shares from employee equity incentive plans are determined by applying the treasury stock method to outstanding stock options, restricted stock units, and employee stock purchase plan. Potentially dilutive common shares from the Series A Mandatory Convertible Preferred Stock are determined by applying the if-converted method on the outstanding Series A Mandatory Convertible Preferred Stock and separately for the Series A Mandatory Convertible Preferred Stock dividends. Under the if-converted method, the Series A Mandatory Convertible Preferred Stock dividends are added back to net income attributable to Bruker Corporation common shareholders and the Series A Mandatory Convertible Preferred Stock is assumed to have been converted at the beginning of the period, determined using the average common stock price for the period, with the resulting common shares included in the weighted average number of common shares outstanding, if the effect is dilutive. Because the Company reported a net loss for the three and nine months ended September 30, 2025, the number of shares used to calculate diluted net loss per common share for those periods is the same as the number of shares used to calculate basic net loss per common share because the potentially dilutive shares would have been antidilutive if included in the calculation.

The following common share equivalents have been excluded from the computation of diluted weighted average common shares outstanding, as their effect would have been anti-dilutive (amounts in millions of shares):


	Three Months Ended September 30,				Nine Months Ended September 30,
	2025		2024		2025		2024
Stock options, restricted stock units, and employee stock purchase plan		1.3		0.3		1.3		0.3
Series A Mandatory Convertible Preferred Stock		5.4		—		1.8		—
