Full Year Summary

LEHIGH VALLEY, Pa. (October 19, 2012) – Air Products (NYSE:APD) today reported net income of $305 million* and diluted earnings per share (EPS) of $1.42* on a non-GAAP, continuing operations basis, for its fiscal fourth quarter ended September 30, 2012. This excludes: an after-tax impairment charge of $127 million, or $0.59 per share, for the restructuring of our photovoltaic business; an after-tax charge of $35 million, or $0.16 per share, for exiting the polyurethane intermediates business; and an after-tax charge of $6 million, or $0.03 per share, to write-down assets following a customer bankruptcy and mill shutdown.

On a GAAP basis, net income and diluted EPS from continuing operations were $137 million and $0.64, respectively, for the quarter.

The discussion of fourth quarter results and guidance in this release is based on non-GAAP continuing operations. A reconciliation to GAAP results can be found at the end of this release.*

Fourth Quarter Financial Results

Fourth quarter revenues of $2,606 million increased four percent versus prior year. On an underlying basis, sales were up four percent on higher volumes in the Tonnage Gases, Equipment and Energy, and Electronics and Performance Materials segments. Acquisitions contributed six percent, which was offset by lower energy pass-through and a stronger dollar. Operating income of $408 million was up three percent versus prior year. Operating margin of 15.7 percent was down 10 basis points.

Sequential sales grew 11 percent, with underlying sales up three percent on higher volumes in the Tonnage Gases, Equipment and Energy, and Electronics and Performance Materials segments. Acquisitions contributed six percent. Operating income grew three percent sequentially.

For fiscal 2012, sales of $9,612 million decreased one percent, with base volume growth and acquisitions more than offset by lower energy pass-through and a stronger dollar. Operating income of $1,534 million was down one percent and diluted EPS of $5.40 increased one percent from the prior year.

Commenting on the fiscal year, John McGlade, chairman, president and chief executive officer, said, “The fourth quarter was a continuation of the economic trends that we have seen throughout the year, with global manufacturing growth continuing to slow. This has led to weak volumes in 2012, which we have been able to offset with increased productivity and cost reductions.

“During this past year we made a number of portfolio moves, including selling our European homecare business, purchasing Indura to enhance our Latin American position; buying the other half of our DA NanoMaterials joint venture; and taking a 25% stake in AHG, the largest industrial gases company in Saudi Arabia. In this most recent quarter, we continued our efforts to further position ourselves for the future by exiting our polyurethane intermediates business and restructuring our photovoltaic businesses.”

Outlook

Looking ahead, McGlade said, “We are starting our 2013 fiscal year with weak economic momentum worldwide. Our focus will be on taking actions in the areas that we believe can have the greatest impact on improving margins and returns. They include loading our Merchant assets, executing our new Tonnage investments on time and on budget; continuing to make improvements in our Electronics and Performance Materials segment and achieving even better productivity.”

The company today announced initial guidance for fiscal year 2013 EPS in the range of $5.65 to $5.85 per share. For the first quarter of fiscal 2013 ending December 31, 2012, EPS is expected to be between $1.26 and $1.31 per share.

The company also announced that it expects capital spending in fiscal year 2013 to be between $2.0 and $2.2 billion.

Capital Expenditures

We utilize a non-GAAP measure in the computation of capital expenditures and include spending associated with facilities accounted for as capital leases. Certain contracts associated with facilities that are built to provide product to a specific customer are required to be accounted for as leases, and such spending is reflected as a use of cash within cash provided by operating activities, if the arrangement qualifies as a capital lease. Additionally, the purchase of noncontrolling interests in a subsidiary is accounted for as an equity transaction and will be reflected as a financing activity in the statement of cash flows.

(Millions of dollars, unless otherwise indicated)

1. DISCONTINUED OPERATIONS

In January 2012, the Board of Directors authorized the sale of our Homecare business, which had previously been reported as part of the Merchant Gases operating segment.

On 8 January 2012, we reached an agreement for The Linde Group to purchase our Homecare business in Belgium, Germany, France, Portugal and Spain. This business represented approximately 80% of our total Homecare business revenues.

The transaction with Linde closed on 30 April 2012. Total sale proceeds of €590 million ($777) were received in cash at closing. This amount included contingent proceeds of €110 million ($144) related to the outcome of certain retender arrangements. The gain related to the contingent proceeds is deferred in other noncurrent liabilities and will be recognized in the results of discontinued operations when the contingencies are resolved and the final proceeds are realized per the terms of the agreement. We are also entitled to additional cash proceeds based upon collection of accounts receivable. As of 30 September 2012, €26 million ($32) was received and we anticipate receipt of the remaining €6 million ($8) during the next fiscal year. A gain of $207.4 ($150.3 after-tax, or $.70 per share) was recognized on the sale of this business in the third quarter of fiscal year 2012.

We are actively marketing the remaining portion of the Homecare business, which is primarily in the United Kingdom. We hope to close on the sale of this business before the end of calendar year 2012. In the third quarter of 2012, we recorded an impairment charge of $33.5 ($29.5 after-tax, or $.14 per share) to write down the remaining business to its estimated net realizable value. Additional charges may be recorded in future periods dependent upon the timing and method of ultimate disposition.

The Homecare business is being accounted for as a discontinued operation. The results of operations and cash flows of this business have been removed from the results of continuing operations for all periods presented. The assets and liabilities of discontinued operations have been reclassified and are segregated in the consolidated balance sheets.

2. BUSINESS RESTRUCTURING AND COST REDUCTION PLANS

In 2012, the company recorded an expense of $327.4 ($222.4 after-tax, or $1.03 per share) for business restructuring actions and cost reduction plans in our Polyurethane Intermediates, Electronics and European Merchant businesses. The net loss is reflected on the consolidated income statements as “Business Restructuring and Cost Reduction Plans.” The charges for these plans are excluded from segment operating income.

During the second quarter of 2012, we recorded an expense of $86.8 ($60.6 after-tax, or $.28 per share) for actions to remove stranded costs resulting from our decision to exit the Homecare business, the reorganization of the Merchant business and actions we are taking to right size our European cost structure in light of the challenging economic outlook. This charge includes $80.8 for severance and other costs associated with the elimination of approximately 600 positions and $6.0 for the write-down of certain assets. The charge relates to the businesses at the segment level as follows: $77.3 in Merchant Gases, $3.8 in Tonnage Gases, and $5.7 in Electronics and Performance Materials. The planned actions are expected to be completed by the end of the second quarter of fiscal year 2013.

During the fourth quarter of 2012, we completed actions in the Polyurethane Intermediates (PUI) business to improve costs resulting in a net expense of $54.6 ($34.8 after-tax, or $.16 per share). The company sold certain assets and the rights to a supply contract for $32.7 in cash at closing. A supply arrangement with terms at fair market value was established with the buyer to serve the retained product supply contracts so that our PUI production facility in Pasadena, TX could permanently close. In connection with these actions, we recognized an expense of $26.6, for the net book value of assets sold and those committed to be disposed other than by sale. The remaining charge was primarily related to contract terminations and an environmental liability. The PUI facility will be dismantled, with completion expected in fiscal year 2013. The costs to dismantle will be expensed as incurred and reflected in continuing operations in the Tonnage Gases business segment. Since we will have material ongoing involvement with the business through retained PUI product supply contracts, the results of this business will continue to be reflected in continuing operations in the Tonnage Gases Segment.

During the fourth quarter of 2012, we completed an assessment of our position in the photovoltaic (PV) market resulting in $186.0 of expense ($127.0 after-tax, or $.59 per share) primarily related to the Electronics and Performance Materials business segment. Air Products supplies the PV market with both bulk and onsite supply of gases including silane. The PV market has not developed as expected and as a result, the market capacity to produce silane is expected to exceed demand for the foreseeable future. As a result, we have entered into negotiations to terminate a long-term, take-or-pay contract. We recorded a charge of $93.5 for an offer that we made to terminate the contract. Although a settlement could differ from this amount, we do not expect it to be material to our financial position. It is uncertain when a settlement will be reached. The remaining charge was recorded in connection with the expected loss on purchase commitments, the disposal of certain assets serving PV and Electronics customers, the write-down of inventory to its net realizable value, and the write-down of accounts receivable.

3. BUSINESS COMBINATIONS

Indura S.A.

On 1 July 2012, we acquired a 51.8% controlling equity interest in the outstanding shares of Indura S.A., from the majority shareholder. On 3 July 2012, we acquired an additional 13.0% equity interest from other shareholders. Following the acquisition date, 100% of the Indura S.A. results are consolidated in our financial statements. The portion of the business that is not owned by the company is recorded as noncontrolling interests. We paid cash consideration in Chilean pesos (CLP) of 345.5 billion ($690) and assumed debt of CLP113.8 billion ($227) for these interests. This preliminary purchase price is subject to working capital and debt adjustments which have not yet been completed. Under the purchase agreement, we have a commitment to purchase an additional 2.0% equity interest within twelve months of the acquisition date. The agreement also provides the largest minority shareholder a right to exercise a put option to require Air Products to purchase up to a 30.5% equity interest during the two-year period beginning on 1 July 2015, at a redemption value equal to fair market value (subject to a minimum price based upon the acquisition date value escalated by an inflation factor). Prior to the acquisition, Indura S.A. was the largest independent industrial gas company in South America. Indura S.A.’s integrated gas and retail business comprises packaged gases and hardgoods, liquid bulk, healthcare and on-sites.

The acquisition of Indura S.A. was accounted for as a business combination. The results of Indura S.A. have been consolidated within our Merchant Gases business segment. For the quarter ended 30 September 2012, our Merchant Gases business segment includes Indura S.A. revenues of $140.0 and operating income of $9.3, which is net of acquisition related costs we incurred of $5.6.

DuPont Air Products NanoMaterials LLC

On 29 February 2012, we entered into a definitive agreement with E.I. DuPont de Nemours and Co., Inc. to acquire their 50% interest in our joint venture, DuPont Air Products NanoMaterials LLC (DA NanoMaterials). DA NanoMaterials’ revenues for calendar year 2011 were approximately $90.

The acquisition closed on 2 April 2012 for $158 ($147 net of cash acquired of $11) and was accounted for as a business combination. Beginning in the third quarter of 2012, the results of DA NanoMaterials were consolidated within our Electronics and Performance Materials business segment.

Prior to the acquisition date, we accounted for our 50% interest in DA NanoMaterials as an equity-method investment. The fiscal year ended 30 September 2012 includes a gain of $85.9 ($54.6 after-tax, or $.25 per share) as a result of revaluing our previously held equity interest to fair market value as of the acquisition date. This gain is reflected on the consolidated income statements as “Gain on previously held equity interest.”

4. INCOME TAXES

Q1 Spanish Tax Settlement

We were challenged by the Spanish tax authorities over income tax deductions taken by certain of our Spanish subsidiaries during fiscal years 2005-2011. Although we continue to believe that all positions taken were compliant with applicable laws, in November 2011 we reached a settlement with the Spanish tax authorities for €41.3 million ($56) in resolution of all tax issues under examination. Of this settlement, $43.8 ($.20 per share) increased our income tax expense and had a 3.3% impact on our effective tax rate for the fiscal year ended 30 September 2012. The cash payment for the settlement was principally paid in January 2012.

Q2 Spanish Tax Ruling

As of 30 September 2011, our unrecognized tax benefits included an amount related to certain transactions of a Spanish subsidiary for years 1991 and 1992, a period before we controlled this subsidiary. In March 2009, the Spanish appeals court (Audiencia Nacional) ruled in favor of our Spanish subsidiary. The Spanish government appealed this court decision to the Spanish Supreme Court, and as a result, we did not reverse the liability accrued for these unrecognized tax benefits. On 25 January 2012, the Spanish Supreme Court released its decision affirming the decision of the Audiencia Nacional in favor of our Spanish subsidiary. As a result, in the second quarter of 2012, we recorded a reduction in income tax expense of $58.3 ($.27 per share), including interest and penalties, and a reduction in unrecognized tax benefits. The reduction in income tax expense had a 4.4% impact on our effective tax rate for the fiscal year ended 30 September 2012.

5. CUSTOMER BANKRUPTCY

As a result of events which occurred during the fourth quarter of 2012, we recognized a charge of $9.8 ($6.1 after-tax, or $.03 per share) primarily related to the write-off of onsite assets due to a customer bankruptcy and mill shutdown. The customer, which received products from the Tonnage Gases segment, filed for bankruptcy in May 2012. Sales and operating income associated with this customer are not material to the Tonnage Gases segment’s results. We do not expect to recognize additional charges related to this customer.

RECONCILIATION

NON-GAAP MEASURE

(Unaudited)

We utilize a non-GAAP measure in the computation of capital expenditures and include spending associated with facilities accounted for as capital leases and purchases of noncontrolling interests. Certain contracts associated with facilities that are built to provide product to a specific customer are required to be accounted for as leases, and such spending is reflected as a use of cash within cash provided by operating activities, if the arrangement qualifies as a capital lease. Additionally, the purchase of noncontrolling interests in a subsidiary is accounted for as an equity transaction and will be reflected as a financing activity in the statement of cash flows.

The presentation of this non-GAAP measure is intended to enhance the usefulness of information by providing a measure which our management uses internally to evaluate and manage our expenditures.

Below is a reconciliation of capital expenditures on a GAAP basis to a non-GAAP measure.
