National Instruments (Nasdaq: NATI) today announced record Q4 GAAP revenue of $278 million, an increase of 11 percent year-over-year. Non-GAAP revenue was $280 million, representing a 12 percent increase year-over-year. In Q4, the company's large order business, defined as orders greater than $20,000, grew 10 percent year-over-year, and the average order size reached a new all-time record of approximately $4,650.

GAAP net income was $24.3 million in Q4, with fully diluted earnings per share (EPS) of $0.20, and non-GAAP net income was $32.5 million, with non-GAAP fully diluted EPS of $0.27.

The company's non-GAAP results exclude the impact of stock-based compensation, amortization of acquisition-related intangibles, acquisition accounting for deferred revenue and acquisition-related transaction costs. Reconciliations of the company's GAAP and non-GAAP results are included as part of this news release.

"Despite recent economic headwinds, we executed well this quarter as we set a new quarterly revenue record and surpassed the $1 billion annual revenue milestone," said Dr. James Truchard, co-founder, president and CEO. "We believe this success has benefitted from the industry shift toward software-based instrumentation, and I believe our long-term investments in software and modular hardware continue to drive improvements in performance, size and productivity for our customers."

NI graphical system design products, which represented about 95 percent of the company's product portfolio, had approximately 14 percent year-over-year revenue growth in Q4 2011. Sales of NI instrument control products, which represented approximately 5 percent of NI revenue in the quarter, were down approximately 16 percent year-over-year in Q4 2011.

Geographically, revenue in U.S. dollar terms for Q4 2011 compared to Q4 2010 was up 9 percent in the Americas, excluding acquisitions, up 3 percent in Europe and up 11 percent in Asia. In local currency terms, revenue was up 5 percent in Europe and up 8 percent in Asia. Including acquisitions, the Americas revenue was up 21 percent.

As of Dec. 31, NI had $366 million in cash and short-term investments. The National Instruments Board of Directors approved a 40 percent increase in the quarterly dividend to $0.14 per share on the company's common stock payable on March 5 to shareholders of record on Feb. 13. This increase in the dividend reflects the progress NI has made since the 2009 recession in strengthening its business model and investing in growth.

Non-GAAP Presentation

In addition to disclosing results determined in accordance with GAAP, NI discloses certain non-GAAP operating results and non-GAAP information that exclude certain charges. In this news release, the company has presented its revenue, gross profit, gross margin, operating expenses, operating income, operating margin, income before income taxes, provision for income taxes, net income and basic and fully diluted EPS for the three- and 12-month periods ending Dec. 31, 2011 and 2010, on a GAAP and non-GAAP basis. NI is also providing guidance on its non-GAAP revenue and non-GAAP fully diluted EPS. When presenting non-GAAP information, the company includes a reconciliation of the non-GAAP results to the GAAP results. Management believes that including the non-GAAP results assists investors in assessing the company's operational performance and its performance relative to its competitors. The company presents these non-GAAP results as a complement to results provided in accordance with GAAP, and these results should not be regarded as a substitute for GAAP. Management uses these non-GAAP measures to manage and assess the profitability and performance of its business and does not consider stock-based compensation expense, amortization of acquisition-related intangibles, acquisition accounting for deferred revenue, adjustments related to the company's contract dispute with the GSA and acquisition-related transaction costs in managing its operations. Specifically, management uses non-GAAP measures to plan and forecast future periods, to establish operational goals, to compare with its business plan and individual operating budgets, to measure management performance for the purposes of executive compensation including payments to be made under bonus plans, to assist the public in measuring the company's performance relative to the company's long-term public performance goals, to allocate resources and, relative to the company's historical financial performance, to enable comparability between periods. Management also considers such non-GAAP results to be an important supplemental measure of its performance.

This news release also discloses the company's earnings before interest, taxes, depreciation and amortization (EBITDA) and EBITDA diluted EPS for the three- and 12-month periods ended Dec. 31, 2011 and 2010. The company also believes that including the EBITDA results assists investors in assessing the company's operational performance relative to its competitors. A reconciliation of EBITDA and EBITDA diluted EPS to GAAP net income and GAAP diluted EPS is included with this news release.

Forward-Looking Statements

This release contains "forward-looking statements," including statements related to validating the industry shift toward a software-based approach to instrumentation, being optimistic that NI's long-term software investment and the performance, size and productivity advantages of its hardware will allow NI to continue to transform the industry and provide quality solutions to its customers, increasing the dividend being a very effective method of returning cash to shareholders, pressure on short-term margins, leveraging the investments the company made in 2011 to drive sustained revenue growth and drive toward 18 percent non-GAAP operating income and NI's Q1 guidance for revenue, GAAP and non-GAAP EPS, non-GAAP effective tax rate and the amount of NI's GAAP to non-GAAP EPS adjustment. These statements are subject to a number of risks and uncertainties, including the risk of adverse changes or fluctuations in the global economy, component shortages, delays in the release of new products, fluctuations in customer demand for NI products, the company's ability to effectively manage its operating expenses, manufacturing inefficiencies, adjustments to acquisition earn-out accruals, foreign exchange fluctuations, the outcome of the company's dispute with the U.S. government on its GSA contract and the impact of NI's recent and any future acquisitions. Actual results may differ materially from the expected results.
