HALF-YEAR REPORT JANUARY – JUNE 2006

• Biacore continued to make very good progress in the second quarter of 2006. Overall sales increased by 21% to SEK 161.6 million (133.1).

In the first six months of 2006, total sales grew by 20% to SEK 299.5 million (249.1). Excluding the effect of exchange rates, sales increased by 17%. • Operating income for the second quarter increased by 41% to SEK 33.1 million (23.4). This much improved operating result was due to the strong sales performance and an improved gross margin. The operating margin in the second quarter was 20.5% (17.6). Operating income in the first half of 2006 increased by 72% to SEK 64.0 million (37.3). • Net income in the second quarter of 2006 amounted to SEK 23.2 million (113.3).

Diluted earnings per share in the first half-year 2006 were SEK 4.26 (12.85). • On June 20, 2006, GE Healthcare (“GEHC”) announced a public cash offer to the shareholders of Biacore to acquire all outstanding shares in Biacore. Biacore’s shareholders are being offered to tender their shares to GEHC for the consideration of SEK 330 in cash for each share in Biacore. On the same day, the Board of Directors of Biacore issued a statement expressing its opinion that the transaction is in the shareholders’ best interest and unanimously recommended the shareholders in Biacore to accept the offer. The Board’s recommendation is, among other factors, based on a fairness opinion from Carnegie Investment Bank AB that the offer is fair to the shareholders in Biacore from a financial point of view. • Biacore has modified its forecast for the full-year 2006. The Company expects sales to increase at a somewhat higher rate than in 2005 with operating income growing faster than sales. As usual, the Company’s performance will vary between the quarters. The previous forecast stated: “Biacore still expects sales for the full-year 2006 to increase at approximately the same rate as in 2005. Operating income for the full-year is expected to grow at a faster rate than sales. As usual, the Company’s performance will vary between the quarters.”
