2010 full-year EPS of NT$1.91; gross margin hits 30%

(PRNewswire) — United Microelectronics Corporation (NYSE: UMC; TWSE: 2303) ("UMC" or "The Company"), a leading global semiconductor foundry, today announced its unconsolidated operating results for the fourth quarter of 2010.


Overview of Fourth Quarter 2010(1):

Revenue: NT$31.32 billion (US$1.08 billion) with 4.1% QoQ decrease
Gross margin: 32.1%; Operating margin: 21.1%
Capacity utilization: 94%
Net income: NT$6.42 billion (US$220.77 million)
Earnings per share: NT$0.52; earnings per ADS: US$0.089

(1) Unless otherwise stated, all financial figures discussed in this announcement are prepared in accordance with ROC GAAP, which differ in some material respects from generally accepted accounting principles in the United States. They are un-audited, unconsolidated, and represent comparisons among the three-month period ending December 31, 2010, the three-month period ending September 30, 2010, and the equivalent three-month period that ended December 31, 2009. For all 4Q10 results, New Taiwan Dollar (NT$) amounts have been converted into U.S. Dollars at the December 31, 2010 exchange rate of NT$29.08 per U.S. Dollar.

Revenue from 4Q10 was NT$31.32 billion, a 4.1% quarter-over-quarter decrease from NT$32.65 billion in 3Q10, and a 12.9% year-over-year increase from NT$27.75 billion in 4Q09. Gross margin was 32.1%, with 21.1% operating margin, NT$6.42 billion net income, and NT$0.52 earnings per ordinary share. In 2010, revenue for the full year was NT$120.43 billion, with NT$23.90 billion net income, and NT$1.91 earnings per share.

Dr. Shih-Wei Sun, CEO of UMC, said, "UMC is dedicated to the customer-driven development of advanced technologies and foundry manufacturing solutions. This commitment has led to considerable success in our efforts to broaden our customer base, optimize product mix, and boost profit capability. 2010 wafer shipments reached a record high of approximately 4.52 million 8-inch equivalent wafers, with revenue hitting another record high of NT$120.43 billion. Full-year operating profit, EPS, and an ROE of 11% also reached their highest levels in recent years. 2010 capital expenditures were US$1.8 billion. With the expansion of high-end capacities, 65nm and below revenue contribution for 4Q alone reached 35%, with 40nm products increasing to 5% of total revenue. Revenue contribution from 65nm and below products for the full year grew an impressive 170% as well."

Dr. Sun continued, "After experiencing growth momentum for over a year and a half at UMC, we anticipate revenue for the first quarter of 2011 to decline slightly due to appreciation of NT dollar, certain customers undergoing product and technology-node transitions, and other seasonal adjustments. UMC is optimistic about demand for high-end chips this year, with revenue contribution from 40nm growing quarterly in 2011 to become a main revenue driver. We will also begin 28nm customer-product pilot around the middle of this year. To satisfy customers' technology and capacity requirements while ensuring both stable growth and long-term ROE, we plan to invest about the same amount of CAPEX as last year. Looking ahead in 2011, UMC will build upon its solid foundation and continue advancing its technologies and service quality to provide its global customers the most appropriate foundry solutions."

Revenue decreased 4.1% QoQ to NT$31.32 billion from NT$32.65 billion in 3Q10, and increased 12.9% YoY from NT$27.75 billion in 4Q09. Gross profit was NT$10.05 billion, or 32.1% of revenue, compared to NT$10.65 billion, or 32.6% of 3Q10 revenue. Operating income for the quarter was NT$6.60 billion, or 21.1 % of revenue, compared to NT$7.19 billion, or 22.0% of 3Q10 revenue. The decrease in revenue was mainly due to the appreciation of the NT dollar, as guided. Net income in 4Q10 was NT$6.42 billion, compared to NT$8.72 billion in 3Q10.

Earnings per ordinary share for the quarter were NT$0.52. Earnings per ADS (2) were US$0.089. The basic weighted average number of outstanding shares in 4Q10 was 12,450,619,954, compared with 12,449,924,578 shares in 3Q10 and 12,686,971,252 shares in 4Q09. The diluted weighted average number of outstanding shares was 12,576,463,301 in 4Q10, compared with 12,569,431,682 shares in 3Q10 and 12,802,575,731 shares in 4Q09. The fully diluted share count on December 31, 2010 was approximately 13,706,788,000. On December 31, 2010, UMC held 458 million treasury shares acquired from the 13th and 14th share buy-back programs.

(2) One ADS represents five Taiwan-listed ordinary shares.

Detailed Financials Section

Revenue impact from the NT dollar appreciation in Q4 was 3.9%. The decrease in revenue was partially offset by lower depreciation within COGS of NT$5.88 billion, allowing the company to maintain a relatively flat gross margin. The total R&D expense was 7.1% of revenue in 4Q10.


COGS & Expenses
(Amount: NT$ million)	4Q10	3Q10	QoQ % change	4Q09	YoY % change

Operating Income	6,600	7,187	(8.2)	3,744	76.3

Net non-operating income during 4Q10 decreased QoQ to NT$426 million, mainly due to the decrease in cash dividends that UMC received in 3Q10. The negative net investment income was due to decreased valuation of ProMos shares.


Non-Operating Income (Expenses)
(Amount: NT$ million)	4Q10	3Q10	4Q09
Net Non-Operating Income	426	1,937	700

Other Gain (Loss)	79	(220)	(398)

Net cash outflow was NT$6.00 billion in 4Q10. Operating cash inflow was NT$15.31 billion. The rise in investing cash outflow primarily reflects the cash-based CAPEX in 4Q10 of NT$20.03 billion. The NT$907 million of financing cash flow was primarily from the redemption of treasury shares issued to employees from the company's 13th share buyback program. Free cash flow (3) for 4Q10 was negative NT$4.72 billion.

(3) Free cash flow = Operating cash flow – Capital expenditures

Blended Average Selling Price Trend

The blended average selling price (ASP) increased in US dollar terms during 4Q10, mainly due to product mix shifting to more advanced technology.

Shipment and Utilization Rate (6)

(6) Utilization Rate = Quarterly Wafer Out / Quarterly Capacity

Wafer shipments decreased 5.8% sequentially to 1,132K in 4Q10, compared to 1,202K 8-inch equivalent wafers shipped in 3Q10. The overall utilization rate for the quarter was 94%.


Quarterly Capacity Utilization Rate
	4Q10	3Q10	2Q10	1Q10	4Q09
Utilization Rate	94%	>99%	100%	88%	86%
Total Capacity (8" K equivalents)	1,234	1,220	1,183	1,154	1,132

Capacity (7)

(7) Estimated capacity numbers are based on calculated maximum output rather than designed capacity. The actual capacity numbers may differ depending upon equipment delivery schedules, pace of migration to more advanced process technologies, and other factors affecting production ramp-up.

Capacity during the fourth quarter was 1,234K 8-inch equivalent wafers. The increase in total capacity is mainly due to expansion of 65/55nm at Fab 12i. The estimated installed capacity in 1Q11 will increase to 1,259K 8-inch equivalent wafers mainly due to expansion at both Fab 12A and Fab 12i. Some 8-inch fabs' capacity will be lower due to fewer working days in February. The 4% capacity increase in 2010 mainly reflects the advanced capacity conversion from mature nodes and the company's backend loaded capacity execution last year.
