| 1. ORGANIZATION | |
| Rocky Holding, Inc. (“Rocky Holding” or the “Company”) is a Delaware holding company and was incorporated on December 13, 2013. The Company was formed for the purpose of effecting a strategic combination of RF Micro Devices, Inc., a North Carolina corporation (“RFMD”) and TriQuint Semiconductor, Inc., a Delaware corporation (“TriQuint”) through a “merger of equals,” in connection with the transactions contemplated by the Agreement and Plan of Merger and Reorganization, dated as of February 22, 2014 and amended as of July 15, 2014, by and among RFMD, TriQuint and the Company (“Merger Agreement”), and as described in the Company’s Registration Statement on Form S-4 (“Form S-4”) filed with the Securities and Exchange Commission (“SEC”) on April 14, 2014, and as subsequently amended (File No. 333-195236). The Registration Statement was declared effective on July 30, 2014. Prior to the closing of the transactions, Rocky Holding will form two direct subsidiaries, Trident Merger Sub and Rocky Merger Sub. Pursuant to the Merger Agreement, Trident Merger Sub will merge with and into TriQuint, and Rocky Merger Sub will merge with and into RFMD (the “Mergers”). As a result of the Mergers, TriQuint and RFMD will each become a wholly owned subsidiary of Rocky Holding. It is anticipated that prior to completion of the Mergers, Rocky Holding will change its name, adopt a NASDAQ symbol for its common stock and register a new trade name and logo that reflect the key attributes of the combined Company. As a result of the transactions contemplated by the Merger Agreement, former TriQuint stockholders and former RFMD shareholders will own common stock in Rocky Holding. Rocky Holding’s principal executive offices are currently located at 7628 Thorndike Road, Greensboro, NC 27409-9421 and its telephone number is (336) 664-1233. | |
| The Company has not commenced operations, has no significant assets or liabilities, and has not carried on any activities other than those incidental to its formation and the matters contemplated by the Merger Agreement. As of June 28, 2014, RFMD is the Company’s sole stockholder and the Company does not hold any equity interest in any other legal entity. |

| The accompanying unaudited Condensed Financial Statements of the Company have been prepared in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) pursuant to the rules and regulations of the SEC regarding interim financial reporting. Accordingly, the unaudited condensed financial statements do not include all of the information and footnotes required by U.S. GAAP for complete financial statements and should be read in conjunction with the Company’s Form S-4.

Although these estimates are based on management’s best knowledge of current events and actions that the Company may undertake in the future, actual results may be different from these estimates. The results of operations for the three months ended June 28, 2014 are not necessarily indicative of the results to be expected for any future period or the full fiscal year. | |
| The Company uses a 52- or 53-week fiscal year ending on the Saturday closest to March 31 of each year.
