EBITDA for the first three quarters of this year was NOK 33,732 million (USD 3,876 million), which was an increase of NOK 19,102 million versus the corresponding period in 1999. The increase in the third quarter was NOK 6,597 million. Operating income for the first three quarters of 2000 was NOK 21,223 million (USD 2,366 million), which was an improvement of NOK 16,220 million compared with the same period last year while the improvement in the third quarter was NOK 5,323 million. The substantial improvement was primarily the result of a significantly higher crude oil price and increased oil production in addition to higher margins and business volumes in Light Metals and Energy. Plant Nutrition also showed positive results as a result of cost reductions and higher margins. Hydro's net income for the third quarter of 2000 was NOK 3,896 million (USD 434.6 million), or NOK 14.90 (USD 1.66) per share, a six-fold improvement compared to the same period in 1999. The third quarter income was positively impacted by the sale of Hydro's interests in Dyno ASA and Sapa Autoplastics AB, as well as the sale of Saga Petroleum UK, all included in "Other Income". Collectively, these transactions provided Hydro a net profit of about NOK 1,600 million, which corresponds to NOK 6.10 per share. Earnings for non-consolidated investees in the first three quarters of 2000 increased by 73% to NOK 541 million compared with the same period last year. For the third quarter earnings increased by 17% to NOK 146 million compared with the same period last year. The growth was attributed to better earnings for companies within both Light Metals and Agriculture. Cash flow from operations in the first three quarters of 2000 was NOK 22.6 billion, an increase of 12.1 billion. The growth was primarily due to improved earnings. Hydro's investments in the first three quarters of 2000 totaled NOK 10.9 billion. About 53% of this was within the oil and gas operations. 3

Operating income was more than four-fold higher than in the first three quarters of 1999. The favorable change was mainly attributed to significantly higher oil and gas prices, together with an approximate 30% increase in oil and gas production stemming primarily from the acquisition of Saga Petroleum. Operating income in the third quarter of 2000 compared to the corresponding period of 1999 improved more than threefold. The increase was primarily due to higher prices, while production was 3% lower than in the same period last year. Hydro's oil and gas production in the third quarter 2000 averaged 367,000 barrels of oil equivalents per day, which was 3% lower than average production in the third quarter of 1999. The drop in production due to the sale of Saga Petroleum UK in August was about 22,000 barrels per day during the third quarter. Production has been lower than expected because of less gas extraction, as well as longer maintenance shut-down periods, and later than anticipated production build-up at Oseberg Sør. The average price of crude oil in the third quarter of 2000 was USD 30.0 per barrel, compared with USD 20.1 per barrel in the corresponding period of 1999. Stated in Norwegian kroner, the oil price was 70% higher. Average realized gas prices were also about 70% above prices in the third quarter of last year. Earnings were impacted by NOK 437 million in exploration costs during the third quarter, compared to NOK 423 million in the corresponding period last year. In Angola, Hydro was offered an interest of 30% in the deep water licence Block 34. The Angolan state oil company, Sonangol, will act as licence operator with Hydro as technical assistant. 4

Energy EBITDA and operating income for Energy in the first three quarters of 2000 were NOK 1,550 million and NOK 1,448 million, respectively. EBITDA and operating income each showed an increase of about 70% versus the first three quarters of last year, excluding one-time adjustments of NOK 123 million connected to the closure of a project in Ireland. The third quarter of this year showed a 42% improvement compared with the same period last year. High refinery margins contributed to an improvement in operating income by NOK 321 million within oil trading and refining activities in the first nine months of 2000 and an improvement of NOK 66 million in the third quarter this year, compared with corresponding periods in 1999. Income for the third quarter included a NOK 71 million loss in crude oil trading. Earnings from gas activities in Continental Europe were improved by NOK 52 million compared to the third quarter of last year. This arose from increased activity and improved margins. Electricity production in the third quarter of 2000 was 16% higher than in the same period last year, however market prices were comparatively lower, which resulted in about the same income for the third quarter this year compared with 1999. Oil Marketing EBITDA and operating income for Oil Marketing in the third quarter of 2000 were NOK 98 million and NOK 45 million, respectively. The corresponding figures in 1999 were NOK 144 million and NOK 65 million. Reduced earnings were attributed to lower realized margins, mainly due to high oil prices during the period. Hydro's share of net income in the retail marketing company, Hydro Texaco, in the first three quarters of this year was NOK 68 million, a reduction of NOK 16 million compared with the same period last year.

EBITDA in the third quarter this year increased by NOK 5

371 million. Operating income in the first nine months of this year was NOK 2,723 million, of which NOK 837 million was recorded in the third quarter. The improvement in the first nine months and in the third quarter of 2000 was primarily due to higher realized metal prices, a higher USD exchange rate, continued good results within metal trading activities, and slightly increased sales volumes. The average realized aluminium price for the third quarter was USD 1,502 per tonne against USD 1,430 per tonne in the corresponding period last year. The average realized aluminium price for the first nine months was USD 1,519 per tonne against USD 1,357 per tonne in the corresponding period last year. At the end of the third quarter, Hydro had contracts in place for about 80% of this year's remaining production at a price of approximately USD 1,540 per tonne. Changes in the LME price can result in significant fluctuations due to markedto-market adjustments of the sales contracts. Earnings for metal trading activities in the first nine months of 2000 were high and substantially above the level realized in the corresponding period of 1999. A large part of the positive result can be attributed to exceptionally good earnings from alumina trading tied to high activity levels and high prices. Earnings in the third quarter of this year were at about the same level as the second quarter, including a one-time effect within alumina trading where NOK 60 million was realized in connection with the settlement of a long-term contract. Earnings from the trading activities are expected to decrease in the fourth quarter and in 2001, due to an anticipated lower activity level and weaker market for alumina. Hydro's trading volume in the U.S. will be negatively impacted from the fourth quarter 2000 due to the interim reduction in production capacity of about 50,000 tonnes in annual output by the tolling agreement partner, Goldendale Aluminium Company. The reason for the reduction is due to high power prices in the Pacific Northwest region of the U.S. Aluminium Extrusion EBITDA for Aluminium Extrusion in the first nine months of this year increased by 29% to NOK 1,013 million while EBITDA for the third quarter was NOK 310 million, an increase of 19% compared to the same period in 1999. Operating income was NOK 548 million in the first three quarters of 2000 and NOK 170 million in the third quarter. The improvement in the first nine months was largely due to higher volumes, while margins remained unchanged versus comparable periods last year. Extrusion Europe showed strong earnings in the first three quarters of 2000, while earnings in the third quarter were about the same as last year. Growth in new orders in the third quarter showed some reduction, however the activity level remains high. Heat Transfer, the business unit that produces automotive components, has continued to experience performance setbacks compared with last year, mainly due to pressure on margins in Europe and the start-up of a new U.S. production unit for welded pipe. Building Systems in Europe has continued to show steady progress. The integration of Wells Aluminium, the U.S. company purchased in the first quarter, is going according to plan, but it has suffered a negative earnings impact due to a generally weaker market, especially within the truck sector. Other Light Metals EBITDA and operating income for Aluminium Rolled Products in the first nine months of 2000 were both lower than in the same period of last year. Earnings in the third quarter were adversely impacted by lower production and higher costs at the Holmestrand rolling mill, stemming from irregular operations after a maintenance shutdown this summer. The rolling mills have an adequate order situation. The market for coated products shows continued strong growth, but margins are under pressure. Automotive Structures in the first three quarters and third quarter of this year showed a significantly improved EBITDA compared with last year. Though experiencing underlying improvements, the largest contribution to a stronger EBITDA was a profit of NOK 72 million in the third quarter from the sale of Hydro's 40% interest in Sapa Autoplastics AB. The operating income for the first nine months of 2000 was negative, but better than the same period last year. Magnesium had a weaker EBITDA and operating income in the first three quarters and third quarter of 2000 versus the same periods last year. Sales volumes were higher, but realized margins were lower, mostly due to lower market prices. Demand for magnesium is strong, yet increased export from China more than offsets demand growth and contributes to considerable price pressure. 6

Operating income was NOK 800 million for the first three quarters of 2000 versus an operating loss of NOK 629 million for the same period in 1999. EBITDA for the first nine months was affected by non-recurring charges of NOK 417 million compared to NOK 367 million in 1999, while corresponding figures for the third quarter this year were NOK 67 million versus NOK 198 million in 1999. The underlying improvement in EBITDA year to date was NOK 1,628 million. Non-recurring items this year comprised approximately NOK 300 million due to the closure of plants and about NOK 200 million in costs associated with additional workforce reductions. The reversal of provisional losses tied to an ammonia contract provided a positive effect of approximately NOK 100 million. EBITDA in the third quarter of 2000 was NOK 516 million, an increase of NOK 687 million compared to the corresponding period last year, while operating income rose by NOK 668 million to NOK 65 million. The improvement in performance for third quarter was due to a combination of cost-reduction initiatives and favorable market effects. Of the total NOK 687 million posted for improvements in the third quarter, approximately NOK 345 million resulted from cost-savings, NOK 130 million from lower non-recurring items, and the remaining NOK 212 million from improved margins. The margin was negatively impacted by higher energy costs that were about NOK 200 million higher than the third quarter of 1999. Fixed costs in the first three quarters of 2000 were reduced by approximately NOK 845 million compared with the same period last year. Since 1998, accumulated savings in fixed costs in Plant Nutrition activities have totaled NOK 1.3 billion and NOK 450 million in variable costs. The work to achieve further cost reductions in Plant Nutrition activities are in line with the targets of the Agenda 99 improvement program and on schedule in relation to the goals set by the Hydro Agri Turnaround program. Plant Nutrition has reduced its workforce by about 2,000 people since January 1999. The international fertilizer markets showed consistent positive development through the third quarter. Urea prices were 30% higher at the end of the quarter compared with the beginning of this year. European prices for nitrogen fertilizer increased significantly in relation to European exchange rates, yet when converted to the US dollar, nitrogen fertilizer prices have not kept up with urea price increases. As a result, the nitrogen profit margin in Europe, compared to urea, continues to be low. The positive development in European prices continued through the third quarter after a low starting point for the new fertilizer season. Because of normal seasonal swings, the price effect from the second to the third quarter had a negative impact on European deliveries. New contracts for the fourth quarter are at significantly higher price levels than in the third quarter. 7

On 6 July, Hydro acquired 58% of the shares in Adubos Trevo S.A., a Brazilian fertilizer company with production capacity of 1.7 million tonnes. The company is expected to bring economies of scale to Hydro's fertilizer activities in Latin America. Gas and Chemicals EBITDA for Gas and Chemicals in the first nine months of 2000 showed an increase of 18%, while the operating income increased 25% in relation to 1999. The favorable change was primarily due to write-downs of NOK 61 million in the third quarter last year. A strong rise in the price of ammonia and natural gas together with reduced prices for technical nitrates have collectively put pressure on profit margins for nitrogen-based products. This has largely been offset by significant cost reductions. A/S Korn- og Foderstof Kompagniet KFK KFK achieved an EBITDA of NOK 395 million for the first three quarters of 2000, approximately the same amount as in the same period last year. The EBITDA this year was positively impacted by the sale of the animal feed operation for NOK 89 million. In the third quarter, EBITDA was NOK 151 million compared with NOK 206 million in the period last year. The operating income was NOK 58 million for the first nine months and NOK 57 million in the third quarter of 2000. KFK's fish feed activities revealed weaker earnings despite a volume increase of 19% in relation to last year, when it realized especially good profit margins. The competitive situation in the Danish feed and grain market has, together with increasing energy prices, contributed to a declining profit margin. Petrochemicals 411 275 173 282 EBITDA 730 563 72 185 78 190 Operating income (loss) 453 (93) EBITDA and operating income for Petrochemicals in the first nine months of 2000 were NOK 730 million and NOK 453 million, respectively. In 1999, the EBITDA included a pre-tax gain of NOK 383 million on the sale of Mabo AS and Hydro Coatings. Excluding these gains, the underlying improvement in EBITDA was about NOK 550 million. The progress was mainly due to a 65% increase in the price of S-PVC compared to last year. However, this was slightly offset by increased material costs for natural gas liquids and purchased ethylene. Prices for caustic soda weakened by 11% compared to the first nine months of last year. In the third quarter, EBITDA and operating income were NOK 282 million and NOK 190 million, respectively. Third quarter 1999 includes a pre-tax gain from the sale of Hydro Coatings of NOK 234 million. The underlying improvement excluding this gain was approximately NOK 100 million compares with the third quarter 1999 and is primarily due to higher prices for S-PVC. The price of S-PVC leveled out toward the end of the third quarter this year. Further price pressure during the the last quarter of 2000 is expected. 8

Net financial expense in the first nine months of 2000 was NOK 2,722 million, compared to NOK 820 million of last year. In the first nine months of the current year net financial items were affected by a currency loss of NOK 1,079 million, mainly as a result of a higher USD exchange rate. In the third quarter of 2000, net financial expense was NOK 733 million compared with NOK 435 million in the previous year. The net financial expense for the third quarter of 2000 included a net currency loss of NOK 432 million compared with a currency gain of NOK 295 million in the previous year. Net financial expense in the third quarter of 1999 included NOK 303 million related to losses on Saga's price hedging program. Capitalized interest on plant under construction totaled NOK 530 million in the first nine months of this year, compared with NOK 654 million in the previous year. Capitalized interest was NOK 194 million in the third quarter of 2000 and NOK 290 million in the same period of last year. Net interest bearing debt of NOK 30.9 billion declined by NOK 12.1 billion since the end of 1999. As of 30 September, 2000, Hydro's debt/equity ratio, calculated as long-term debt divided by equity plus minority interest, was 0.62. Adjusted for any excess cash and cash equivalents over a normal level, the debt/equity ratio was at Hydro s target of 0.5; Hydro's target. Thus, the adjusted ratio is at the same level as it was before the Saga acquisition. Taxes The provision for current and deferred taxes in the first nine months of 2000 was NOK 11,431 million, equivalent to 56% of pre-tax income, primarily current tax. The corresponding figure for the same period of last year was NOK 3,122 million equivalent to 54% of pre-tax income. The tax percentage was influenced by the gains recorded as "Other income" which were taxed at a lower rate. Excluding the effects of these gains, the tax percentage would have been approximately 61%. The increase in the effective tax rate was due to increased earnings from oil activities compared to the same period last year. Oslo, 16 October 2000 The Board of Directors 9

EBITDA* and reconciliation to income before taxes and minority interest The transition to the new steering model, Value-Based Management, has moved Hydro's focus to cash flow-based indicators, before and after taxes. EBITDA, defined as income (loss) before tax, interest expense, depreciation, amortization, writedowns and certain other financial items, is an approximation of cash flow from operations before tax. It is being used as a measure to assess performance in Hydro's operational areas and business segments. Accordingly, EBITDA is a measure that includes results from non-consolidated investee companies and gains and losses on sales of activities classified as "Other Income (Loss)" in the income statement. It excludes depreciation, writedowns and amortization, as well as amortization of goodwill in non-consolidated investee companies. EBITDA should not be construed as an alternative to operating income and income before taxes as an indicator of the company's operations in accordance with generally accepted accounting principles. Nor is EBITDA an alternative to cash flow from operating activities in accordance with generally accepted accounting principles. Hydro's definition of EBITDA can differ from that of other companies. Hydro has also introduced cash return on gross investment (CROGI) as an annual rate of return measure. CROGI is defined as gross cash flow after taxes, divided by gross investment 1). Gross cash flow is defined as EBITDA less taxes, while gross investment is defined as total assets plus accumulated depreciation, amortization and writedowns, less shortterm interest-free debt 2). The EBITDA figures by core business area are presented in the table below, in addition to the reconciliation from EBITDA to income before taxes and minority interest. 1999 2000 2000 2000 EBITDA 2000 1999 1999 Year 4,075 6,982 7,697 7,976 Hydro Oil and Energy 22,655 8,265 13,579 1,065 1,803 1,659 1,566 Hydro Light Metals 5,028 2,687 3,760 150 1,041 1,276 846 Hydro Agri 3,163 1,450 1,141 500 523 364 1,999 Other 2,886 2,228 3,464 5,790 10,349 10,996 12,387 Total 33,732 14,630 21,944 3,202 3,173 3,282 2,844 - Depreciation 9,299 7,121 10,494 - - - - - Write-down - - 444 - Amortization of goodwill 14 19 19 16 of non-consolidated investees 54 41 79 750 883 867 746 - Interest expense 2,496 1,766 2,566 (295) 266 381 432 - Net foreign exchange loss (gain) 1,079 (254) 304 85 96 53 61 - Other financial items 210 157 184 2,034 5,912 6,394 8,288 Income before tax and minority interest 20,594 5,799 7,873 EBITDA information by segment in each of the core business areas, as well as an explanation of the financial performance of each segment, is included in the presentation of the business areas. *EBITDA: Earnings Before Interest, Taxes, Depreciation and Amortization. 1) Deferred tax assets are not included in gross investment. 2) Deferred taxes and taxes payable are not deducted from gross investment. 13

The consideration offered consisted of one Hydro share for each three Saga shares with an additional cash payment in NOK in an amount which ensured that the aggregate consideration per Saga share had a value of NOK 135. All of Saga s ordinary shares were acquired representing a total value of NOK 20.2 billion. An agreement between Hydro and Statoil required the transfer of interests in certain of Saga s oil and gas production licenses with a total market value of NOK 8.4 billion to Statoil with effect from 1 July, 1999. The consideration received in exchange for such interests consisted of Statoil s shares in Saga together with a cash payment of NOK 4.5 billion, which was paid in December 1999. Hydro s acquisition of the Saga ordinary shares, amounting to NOK 16.2 billion, was financed by a share issue of NOK 11.6 billion and a cash payment of NOK 4.6 billion. The acquisition resulted in a total excess value for Hydro of NOK 12.6 billion and this was allocated to oil and gas production licenses to be depreciated by the unit of production method. The excess value could be adjusted when a final decision is taken by the Norwegian authorities regarding Saga s tax position. Saga s activities were consolidated in Hydro s accounts with effect from 1 July, 1999.
