Exhibit 99.1

The pro forma adjustments in the following tables are based on the best information available and assumptions that management believes are factually supportable and reasonable; however, such adjustments are subject to change. In addition, such adjustments are estimates. The unaudited pro forma consolidated information is for illustrative and informational purposes only and is not intended to reflect what our consolidated results of operations would have been had the disposition occurred prior to the dates indicated and is not necessarily indicative of our future consolidated results of operations. 

For each of the periods presented, the column labeled “Pro Forma” reflects the Company’s revenue and cost of revenue as if the Transaction had already occurred and the Company had been selling its T-SPOT.TB test kits at an estimated market rate. For purposes of the pro forma adjustments, revenue is based on U.S. laboratory test volumes, as opposed to shipments of T-SPOT.TB test kits. This methodology may not be indicative of the future timing of revenue. 

The As Reported and Pro Forma columns include blood donor screening revenue and cost of revenue, despite the Company’s decision to exit this business upon the closing of the Transaction.
