Haemonetics Reports 8% Revenue Growth for Second Quarter of Fiscal 2012, Adjusted Earnings Per
Share of $0.72 and Updates Previously Provided Full Year Earnings Guidance

Braintree, MA, October 31, 2011— Haemonetics Corporation (NYSE: HAE) today reported second quarter 2012 GAAP net revenues of $179.4 million, up 8%, net income of $13.9 million, down 35%, and earnings per share of $0.54, down 36%. Excluding transformation costs and contingent consideration income, adjusted second quarter net income was $18.7 million, down 7%, and adjusted earnings per share was $0.72, down 9%. Excluding currency impacts, net revenue was up 6% in the quarter.¹

Year to date, Haemonetics reported GAAP net revenues of $350.0 million, up 6%, net income of $30.8 million, down 22%, and earnings per share of $1.18, down 23%. Excluding transformation costs and contingent consideration income, adjusted first half net income was $35.8 million, down 9% and adjusted earnings per share was $1.37, down 11%. Excluding currency impacts, first half fiscal 2012, net revenue was up 4%.¹

Brian Concannon, Haemonetics’ President and CEO, said: “The quality issues with the OrthoPAT^® device recall and HS Core Bowl continued to negatively impact our operating income and earnings per share in the second quarter. We have determined the root cause for both products, and remediation and recovery plans are well underway. However, we have now concluded that we underestimated the costs to remediate and the impact that dealing with the quality issues had on elements of our business. Our revised guidance fully reflects our learning. We expect to put these issues behind us by the end of the fiscal year.”

STRATEGIC AND SEGMENT GROWTH HIGHLIGHTS

Haemonetics continues to make progress expanding its business. The Company reported the following second quarter fiscal 12 highlights:

	•		14% revenue growth in plasma disposables, as increasing collection volumes drives revenues.
	•		7% revenue growth in the software business, a key enabler of blood management solutions.
	•		22% revenue growth in diagnostic disposables products, with rapid uptake by leading US hospitals.
	•		IMPACT® accounts increasing to 226 as more customers embrace the value of blood management.
	•		The OrthoPAT recall remains on track with over 500 devices replaced to date.

In the quarter Haemonetics reported adjusted gross margin of 50.9%, down 170 basis points, and adjusted operating margin of 14.2%, down 270 basis points. The Company’s adjusted operating expenses were $65.8 million, up 10%. Gross and operating margins were significantly impacted by the recall of OrthoPAT devices. The negative impact on operating results associated with the OrthoPAT recall and other product quality initiatives was approximately 180 basis points of gross margin, $4 million of operating earnings or $0.12 per share in the quarter and 170 basis points of gross margin, $7 million of operating earnings or $0.20 per share year to date.

     Mr. Concannon added: “Despite the quality issues, the fundamentals of this business remain strong. With the exception of OrthoPAT^® disposables, where the recall impacted revenues, we saw continued growth across all other product categories. We continue to see a growing demand for our products and services as more customers seek economic savings and improved clinical outcomes using our blood management solutions.”

As noted, in the quarter revenues were $179.4 million, up 8%. A break-down vs. the prior year quarter follows:

Plasma

Plasma disposables revenue was $64.4 million, up 14%. Momentum continued in Haemonetics’ plasma business in the quarter following a cyclical adjustment in the commercial Plasma business last year. Plasma revenues are still being negatively impacted by a change in collection practices in Japan.

Blood bank

Platelet disposables revenue was $42.2 million, up 6%. Platelet revenues continue to benefit from strong sales in emerging markets.

Red cell disposables revenue was $11.6 million, up 3%. Red cell revenues grew due to increasing demand for red cells as the Company leveraged its IMPACT selling approach in the market.

Hospital

Surgical disposables revenue was $16.2 million, up 1%. The Elite^® product launch is expected to accelerate in the second half of fiscal 12. OrthoPAT orthopedic perioperative autotransfusion system disposables revenue was $7.3 million, down 12% and remains impacted by the voluntary recall of pre-2002 devices.

Diagnostics revenue was $5.7 million, up 22%. Revenue growth related to the TEG^® Thrombelastograph^® Hemostasis Analyzer business was also driven by the Company’s IMPACT initiative.

Software Solutions revenue was $17.2 million, up 7%. The enhanced offering of software products for Blood Bank and Hospital customers continues to drive revenue growth.

Equipment and other revenue was $14.8 million, up 4% following a first quarter in which a 13% decline occurred. Equipment revenues are influenced by the timing of tenders and capital budgets.

Haemonetics reported second quarter fiscal 12 revenue growth in all regions with sales up 10% in North America, 9% in Japan, 13% in Asia and 1% in Europe.

Cash Flow and Share Repurchase Activity

The Company reported continued strong cash flows. Excluding transformation costs in fiscal 12 and 11 and deal costs in fiscal 11, adjusted first half operating cash flow was $57.1 million, up 8%, and free cash flow was $33.4 million, up 15%. During the second quarter of fiscal 12, the Company repurchased approximately 852,400 of its common shares in the open market, completing its authorized $50 million repurchase program.

Guidance

The company now expects fiscal year 12 revenue growth of 6-7%, slightly above the high end of its previous guidance range. Plasma is now expected to grow 11-12% and hospital products 0-2% due to the quality remediation. Full year adjusted gross margin is now expected to approximate 52%, operating income $110 — $112 million, earnings per share $3.00 — $3.10 and free cash flow in excess of $70 million.

These new estimates reflect an increase in the estimated full-year impact of the OrthoPAT and HS Core quality issues. The impact on operating income due to lost sales and gross margin and increased quality and regulatory expenses, is now expected to be approximately $13 million or $0.37 per share, up from our previous estimate of $9 million or $0.25 per share.

Full year guidance also includes revised estimates of operations cost savings delays and hospital product sales delays, other than OrthoPAT, enumerated in the table which follows:

Haemonetics Corporation Financial Summary
Reconciliation of Non-GAAP Measures

Haemonetics has presented supplemental non-GAAP financial measures as part of this earnings release. A reconciliation is provided below that reconciles each non-GAAP financial measure with the most comparable GAAP measure. The presentation of non-GAAP financial measures should not be considered in isolation from, or as a substitute for, the most directly comparable GAAP measures. There are material limitations to the usefulness of non-GAAP measures on a standalone basis, including the lack of comparability to the GAAP financial results of other companies.

These measures are used by management to monitor the financial performance of the business, inform business decision making, and forecast future results. Performance targets for management are established based upon these non-GAAP measures. In the reconciliations below, we have removed restructuring and transformation costs from our GAAP expenses. Our restructuring and transformation costs are principally related to HS Core customer related expenses, restructuring of certain departments and the disposal of a product line. We believe this information is useful for investors because it allows for an evaluation of the Company with a focus on the performance of our core operations.

Non-GAAP Gross Profit

The use of these non-GAAP measures allows management to monitor the level of total gross profits without the costs of our business transformation. We establish our budgets, forecasts, and performance targets on this basis.

Non-GAAP S,G&A and Non-GAAP Operating Expenses

The use of this non-GAAP measure allows management to monitor the ongoing level of spend that is necessary to support the business in a period when we are not transforming our business or completing an acquisition of in-process research and development. We establish our budgets, forecasts, and performance targets excluding these costs.

Non-GAAP Operating Income and Non-GAAP Income before Income Taxes

The use of these non-GAAP measures allows management to monitor the level of operating and total pre-tax profits without the costs of our business transformation. We establish our budgets, forecasts, and performance targets on this basis.

Non-GAAP Net Income and Earnings per Share

The use of these non-GAAP measures allows management to monitor the level of net income and earnings per share excluding both the costs of our business transformation, as well as any related tax effects. We establish our budgets, forecasts, and performance targets on this basis.

Presented below are additional Constant Currency performance measures. We measure different components of our business at constant currency. We believe this information is useful for investors because it allows for an evaluation of the Company without the effect of changes in foreign exchange rates. These results convert our local foreign currency operating results to the US Dollar at constant exchange rates of $1.20 per Euro, and 110 Yen to the $1.00. They also exclude the results of our foreign currency hedging program described in Note 7 to our consolidated financial statements in our Form 10-K.

Presented below are additional Constant Currency performance measures. We measure different components of our business at constant currency. We believe this information is useful for investors because it allows for an evaluation of the Company without the effect of changes in foreign exchange rates. These results convert our local foreign currency operating results to the US Dollar at constant exchange rates of $1.20 per Euro, and 110 Yen to the $1.00. They also exclude the results of our foreign currency hedging program described in Note 7 to our consolidated financial statements in our Form 10-K.
