12.	PROFIT/(LOSS) PER SHARE

Basic earnings per ordinary share

Basic earnings/(loss) per ordinary share for the group is computed by dividing the profit after taxation of US$875,000 (2020: loss of US$6,388,000) (2019: loss of US$28,914,000) for the financial year by the weighted average number of ‘A’ ordinary shares in issue. Basic earnings/(loss) per ordinary share for continuing operations is computed by dividing the profit after taxation for continued operations of US$929,000 (2020: loss of US$6,013,000) (2019: loss of US$28,991,000) for the financial year by the weighted average number of ‘A’ ordinary shares in issue.

As at December 31, 2021, this amounted to 83,606,810 shares (2020: 83,606,810 shares) (2019: 83,606,810 shares).

‘A’ ordinary shares		83,606,810			83,606,810			83,606,810

Basic earnings per share denominator		83,606,810			83,606,810			83,606,810

Reconciliation to weighted average earnings per share denominator:
Number of ‘A’ ordinary shares at January 1 (Note 20)		96,162,410			96,162,410			96,162,410
Weighted average number of shares issued during the year*		-			-			-
Weighted average number of treasury shares		(12,555,600	)		(12,555,600	)		(12,555,600	)

Basic earnings per share denominator		83,606,810			83,606,810			83,606,810

* The weighted average number of shares issued during the year is calculated by taking the number of shares issued multiplied by the number of days in the year each share is in issue, divided by 365 days.

Diluted earnings per ordinary share

Diluted earnings/(loss) per ordinary share for the group is computed by dividing the adjusted profit after tax of US$4,299,000 (2020: loss of US$533,000) (2019: loss of US$24,512,000) for the financial year by the diluted weighted average number of ordinary shares in issue of 106,518,650 (2020: 105,024,732) (2019: 101,870,064). Diluted earnings/(loss) per ordinary share for continuing operations is computed by dividing the adjusted profit on continuing operations of US$4,353,000 (2020: loss of US$158,000) (2019: loss of US$24,590,000) for the financial year by the diluted weighted average number of ordinary shares in issue of 106,518,650 (2020: 105,024,732) (2019: 101,870,064). The adjusted profit after tax on continuing operations is computed by adding back the interest expense, accretion interest and movements in the fair value of the derivatives on the exchangeable notes to the loss after taxation for continuing operations.

Under IAS 33 Earnings per Share, diluted earnings per share cannot be anti-dilutive. Therefore, diluted loss per ordinary share in accordance with IFRS would be equal to basic loss per ordinary share when a loss occurs.

The basic weighted average number of ordinary shares for the Group may be reconciled to the number used in the diluted earnings per ordinary share calculation as follows:

	December 31, 2021		December 31, 2020		December 31, 2019
Basic earnings per share denominator (see above)		83,606,810		83,606,810		83,606,810

Diluted earnings per share denominator		106,518,650		105,024,732		101,870,064

The profit/(loss) after tax for the year may be reconciled to the amount used in the diluted earnings per ordinary share calculation as follows:

	December 31, 2021 US$‘000			December 31, 2020 US$‘000			December 31, 2019 US$‘000

Earnings per ADS

In June 2005, Trinity Biotech adjusted its ADS ratio from 1 ADS: 1 ordinary share to 1 ADS: 4 ordinary shares. Earnings per ADS for all periods presented have been restated to reflect this exchange ratio.

Basic earnings per ADS for the Group is computed by dividing the profit after taxation of US$875,000 (2020: loss of US$6,388,000) (2019: loss of US$28,914,000) for the financial year by the weighted average number of ADS in issue of 20,901,703 (2020: 20,901,703) (2019: 20,901,703). Basic earnings per ADS for continuing operations is computed by dividing the profit after taxation of US$929,000 (2020: loss of US$6,013,000) (2019: loss of US$28,991,000) for the financial year by the weighted average number of ADS in issue of 20,901,703 (2020: 20,901,703) (2019: 20,901,703).
