INTERDIGITAL ANNOUNCES SECOND QUARTER 2010 FINANCIAL RESULTS

Expansion of Customer Relationships Drives Strong Revenue Growth and Profitability

KING OF PRUSSIA, PA — July 28, 2010 — InterDigital, Inc. (NASDAQ: IDCC) today announced results for the second quarter ended June 30, 2010.

Highlights for second quarter 2010:

	•		Net income of $35.0 million, or $0.78 per diluted share, a 32 percent increase over second quarter 2009;

	•		Revenue of $91.2 million (which includes $4.9 million related to past sales), a 22 percent increase over second quarter 2009; and

	•		Ending cash and short-term investments totaling $485.8 million.

William J. Merritt, InterDigital’s President and Chief Executive Officer, commented, “We continue to show strong growth in revenues and profitability in the second quarter, driven by new customer agreements and continued strong sales by our customers. Our addition of Capital Semiconductor as a customer for our SlimChip™ core reinforces the strength of this market-ready technology, and opens the possibility of new revenue streams.”

“We expect to continue our strong financial performance as we further expand our base of customers. In particular, we are focusing on expanding our customer base for LTE technology. We have made significant contributions to the worldwide standards bodies in several key areas of LTE technology, including power control, bandwidth on-demand, interference reduction and higher data throughput. These areas are central to the user experience and key to unlocking the potential of wireless communications,” continued Mr. Merritt. “With our pioneering wireless technologies, InterDigital continues to be a leader in building innovative solutions, benefiting users, device manufacturers and operators worldwide.”

Second Quarter Summary

Net income for second quarter 2010 totaled $35.0 million, or $0.78 per diluted share, an increase of 32 percent over second quarter 2009 net income of $26.4 million, or $0.59 per diluted share. Contributions from several new customers including Casio Hitachi Mobile Communications (“CHMC”), Pantech, Cinterion, Enfora, Beceem, and Capital Semiconductor (“CapiSemi”) as well as higher sales by nearly all of our existing per-unit licensees drove higher profitability in the quarter.

Total revenue in second quarter 2010 of $91.2 million, increased 22 percent from $74.9 million reported in second quarter 2009. Patent licensing royalties of $85.1 million increased $12.4 million, or 17 percent, over $72.7 million in second quarter 2009 driven by new agreements signed subsequent to second quarter 2009, the renewal of a patent license agreement in second quarter 2010, which contributed to both per-unit royalties and past sales, and higher sales by nearly all of our existing per-unit licensees. Technology solutions revenue in second quarter 2010 of $6.1 million more than doubled from $2.2 million in second quarter 2009 due to contributions from customers added during first half 2010, Beceem and CapiSemi,

as well as customer sales of products containing the company’s SlimChip modem core platform. Customers that accounted for ten percent or more of the $91.2 million of second quarter 2010 total revenue were Samsung (28 percent) and LG Electronics (16 percent).

Second quarter 2010 operating expenses of $38.1 million increased by $3.4 million, or 10 percent, over $34.7 million reported in second quarter 2009. Total operating expenses in second quarter 2010 included a cumulative charge of $0.9 million to increase the accrual rate for a performance-based cash incentive under the company’s long-term compensation program (“LTCP”). The expectation for an increased payout under the LTCP relates to the addition of new revenue-producing agreements signed in second quarter 2010, and the charge covers the first two and one-quarter years of the three-year performance period ending December 31, 2010. In addition, expenses rose $4.1 million as a result of sublicense fees and other non-personnel expenses to support the technology transfer under the new agreements entered into during first half 2010, new research and development projects initiated in the last twelve months and an increase in costs associated with due diligence related to potential patent acquisition opportunities. These and other increases were offset by the lower level of intellectual property enforcement activity ($2.4 million in second quarter 2010 versus $5.6 million in second quarter 2009).

Net interest and investment income for second quarter 2010 totaled $0.9 million, an increase of 42 percent from $0.6 million in second quarter 2009. The increase was primarily due to higher investment balances in second quarter 2010 as compared to second quarter 2009.

The company’s second quarter 2010 effective tax rate was approximately 35 percent, level with second quarter 2009.

Six Months Summary

The company’s first half 2010 net income totaled $83.8 million, or $1.87 per diluted share, more than double first half 2009 pro forma net income¹ of $41.8 million, or $0.93 per diluted share. The first half 2009 pro forma results do not include a $37.0 million repositioning charge incurred in first half 2009. This year-over-year increase in net income was driven by revenue contributions from several new customers added subsequent to second quarter 2009. On a GAAP-reported basis, first half 2009 net income totaled $17.8 million, or $0.39 per diluted share.

Total revenue in first half 2010 of $207.3 million increased 42 percent from $145.5 million reported in first half 2009. This increase was driven by a $56.8 million, or 40 percent, increase in patent licensing royalties primarily attributable to past sales resulting from the first quarter 2010 patent license agreement signed with CHMC. The remaining increase in patent licensing royalties was primarily attributable to new license agreements signed subsequent to second quarter 2009 with Pantech, CHMC, Cinterion, and Enfora, a renewal of an agreement in second quarter 2010, and a full six months of revenue from the patent license agreement with Samsung signed during first quarter 2009. Technology solutions revenue in first half 2010 of $8.4 million more than doubled from $3.4 million in first half 2009 due to contributions from new technology solutions agreements with Beceem and CapiSemi and customer sales of products containing the company’s SlimChip modem core platform. Customers that accounted for ten percent or more of the $207.3 million of first half 2010 total revenue were Samsung (25 percent), CHMC (16 percent) and LG Electronics (14 percent).

Not including the $37.0 million repositioning charge incurred in first half 2009, first half 2010 operating expenses decreased by 3 percent, or $2.4 million, to $79.6 million compared to first half 2009. This year-over-year decrease was driven by a $7.5 million decrease in development expenses, primarily related to the 2009 repositioning, partly offset by an increase in patent administration and licensing costs related to increased activity in management of the company’s patent portfolio and due diligence associated with patent acquisition opportunities. Total operating expenses in first half 2010 included a cumulative charge

of $1.8 million to increase the accrual rate from 50 percent to 70 percent for a performance-based cash incentive under the company’s LTCP in connection with revenue-producing agreements signed in first half 2010. This charge primarily relates to the first two years of the three-year performance period ending December 31, 2010.

Net interest and investment income for each of first half 2010 and first half 2009 totaled $1.5 million.

The company’s first half 2010 effective tax rate was approximately 35 percent, as compared to the first half 2009 effective tax rate of approximately 36 percent.

In first half 2010, the company generated $66.6 million of free cash flow² compared to $86.5 million in first half 2009. The decrease of $19.9 million in free cash flow was driven primarily by a reduction of $67.3 million in prepayments and fixed fee cash receipts from patent license agreements due to a higher level of such payments received in first half 2009 compared to first half 2010. This decrease was partially offset by an increase in payments from new and current licensees and technology solutions customers of $37.8 million, lower cash requirements for operating expenses and capital investments, and changes in working capital.

Near-Term Outlook

Scott McQuilkin, Chief Financial Officer, commented, “Our second quarter results reflect the growth of our customer base and strong sales from our existing licensees reflecting the rebound in industry mobile phone shipments. We will provide an update on our revenue expectations for third quarter 2010 after we receive and review the applicable patent license and product sales royalty reports. Finally, I am pleased to note that subsequent to the close of the second quarter, we received a scheduled $100 million payment from Samsung.”

¹		Pro forma net income is a supplemental non-GAAP financial measure that InterDigital believes is helpful in evaluating the company’s first half 2010 operating results relative to first half 2009. A limitation of the utility of pro forma net income as a measure of financial performance is that it does not represent the company’s total operating expenses for the period. For purposes of this press release, InterDigital defines “pro forma net income” as net income excluding the expense associated with the repositioning charge and the related tax benefit, both non-recurring items in first quarter 2009. InterDigital’s computation of pro forma net income might not be comparable to pro forma net income reported by other companies. The presentation of this financial information, which is not prepared under any comprehensive set of accounting rules or principles, is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with generally accepted accounting principles (“GAAP”). A detailed reconciliation of pro forma net income to net income, the most directly comparable GAAP financial measure, is provided at the end of this press release.

²		Free cash flow is a supplemental non-GAAP financial measure that InterDigital believes is helpful in evaluating the company’s ability to invest in its business, make strategic acquisitions and fund share repurchases, among other things. A limitation of the utility of free cash flow as a measure of financial performance is that it does not represent the total increase or decrease in the company’s cash balance for the period. InterDigital defines “free cash flow” as net cash provided by operating activities less purchases of property and equipment, technology licenses and investments in patents. InterDigital’s computation of free cash flow might not be comparable to free cash flow reported by other companies. The presentation of this financial information, which is not prepared under any comprehensive set of accounting rules or principles, is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with GAAP. A detailed reconciliation of free cash flow to net cash provided by operating activities, the most directly comparable GAAP financial measure, is provided at the end of this press release.
