EXHIBIT 99 EXHIBIT (b)(6) Investment Banking Presentation to THE SPECIAL COMMITTEE OF THE BOARD OF DIRECTORS OF WANDEL & GOLTERMANN TECHNOLOGIES, INC. March 10, 1998 THE ROBINSON-HUMPHREY COMPANY Investment Bankers Since 1894 - -------------------------------------------------------------------------------- Introduction and Methodology - -------------------------------------------------------------------------------- o The special committee of the Board of Directors of Wandel & Goltermann Technologies, Inc. ("WGTI") has asked Robinson-Humphrey to provide information to the Special Committee in connection with its evaluation of the proposal for the acquisition of WGTI shares currently held by persons other than Wandel & Goltermann Management Holding GmbH ("WG Holding"). o In evaluating a per share purchase price range for the shares of WGTI currently held by persons other than WG Holding, Robinson-Humphrey conducted, among other analyses, a (i) Review of the industry and the competitive climate in which WGTI operates, and its competitive position; (ii) Review of the business, historical financial performance and future prospects of WGTI; (iii) Review of the historical and current market prices and trading patterns of the Common Stock of WGTI; (iv) Review and analysis of the market prices of securities of, and financial data of, other companies engaged in similar businesses as WGTI; (v) Review and analysis of prices and premiums paid in, and other terms of, other recent "going private" acquisition transactions; and a (vi) Discounted cash flow analysis of WGTI. o Robinson-Humphrey also held discussions with members of the senior management of WGTI regarding the Company's past and current business operations, financial condition and future prospects. o Robinson-Humphrey relied without independent verification upon the accuracy and completeness of all of the financial and other information reviewed by it for purposes of its analysis. Robinson-Humphrey assumed that the financial forecasts of WGTI were reasonably prepared on a basis reflecting the best current available estimates and judgements of WGTI's senior management as to the future financial performance of WGTI. o See attached Exhibit A for the historical and projected financial statements Robinson-Humphrey used in its analysis. -1- - -------------------------------------------------------------------------------- Summary of Selected Comparable Company Analysis - -------------------------------------------------------------------------------- o Robinson-Humphrey reviewed and compared certain financial, operating and stock market information of WGTI and two comparable groups of publicly traded companies in the Network Solutions industry. o The "Network Analysis" publicly-traded companies included in our analysis were Applied Digital Access, Concord Communications, Digital Lightwave, Hewlett-Packard, Network Associates, RADCOM, Tekelec and Tektronix. The "Network Management and Equipment" publicly-traded companies included in our analysis include the "Network Analysis" companies plus Dynatech, Fluke, GenRad, Keithley Instruments, MicroTest, Objective Systems Integrators, Retix, TCSI, Teradyne, Bay Networks, Cabletron, Cisco and 3Com. o Robinson-Humphrey calculated current market price as a multiple of book value and as a multiple of estimated earnings per share ("EPS") for calendar 1998 and 1999. The EPS estimates were based on the mean of publicly available earnings estimates made by research analysts as provided by First Call Investor Service. In addition, Robinson-Humphrey calculated firm value (market capitalization plus debt minus cash) to calendar 1997 revenues for each of the publicly traded companies. o Robinson-Humphrey averaged the multiples of the comparable companies in order to apply these multiples to WGTI's values. To accurately reflect average values for statistical purposes, Robinson-Humphrey excluded certain outlying values that differed from the relative groupings of the other values. Robinson-Humphrey believes that these outlying values for certain companies reflect temporary market aberrations that can skew mean values. o With respect to the "Network Analysis" companies, the estimated calendar 1998 price/earnings ratios ranged from 87.9x to 10.0x, with an average of 31.8x, thus implying a value of $19.63 per share for WGTI. The estimated calendar 1999 price/earnings ratios ranged from 43.3x to 10.5x, with an average of 24.1x, thus implying a value of $24.75 per share for WGTI. The current market value to book value multiples ranged from 12.7x to 1.8x, with an average of 6.1x, thus implying a value of $27.13 per share for WGTI. The firm value to calendar 1997 revenue multiples ranged from 7.53x to 1.08x, with an average of 3.11x, thus implying a value of $32.39 per share for WGTI. -2- - -------------------------------------------------------------------------------- Summary of Selected Comparable Company Analysis - -------------------------------------------------------------------------------- o With respect to the "Network Management and Equipment" companies, the estimated calendar 1998 price/earnings ratios ranged from 87.9x to 10.0x, with an average of 24.5x, thus implying a value of $15.10 per share for WGTI. The estimated calendar 1999 price/earnings ratios ranged from 43.5x to 10.5x, with an average of 21.9x, thus implying a value of $22.52 per share for WGTI. The current market value to book value multiples ranged from 12.7x to 1.5x, with an average of 5.2x, thus implying a value of $23.09 per share for WGTI. The firm value to calendar 1997 revenue multiples ranged from 7.53x to 0.61x, with an average of 2.68x, thus implying a value of $28.08 per share for WGTI. o See attached Exhibit B for the implied valuation averages Robinson-Humphrey used in its analysis. -3- - -------------------------------------------------------------------------------- Summary of Selected Mergers and Acquisitions - -------------------------------------------------------------------------------- o Robinson-Humphrey reviewed and compared 21 selected recent mergers and acquisitions in the network solutions industry, including (i) Bay Network's proposed acquisition of Netsation; (ii) Clayton Dubilier's proposed acquisition of Dynatech; (iii) McAfee Associates' acquisition of Network General; (iv) Tivoli Systems' acquisition of Unison Software; (v) Network General's acquisition of Cinco Networks; (vi) Ascend's acquisition of Cascade; (vii) 3Com's acquisition of US Robotics; (viii) Network General's acquisition of 3DV Technology; (ix) Compaq's acquisition of Microcom; (x) Dynatech's acquisition of Itronix; (xi) McAfee Associates' acquisition of FSA; (xii) Computer Sciences' acquisition of Continuum; (xiii) McAfee Associates' acquisition of Vycor; (xiv) Dynatech's acquisition of Synergistic Solutions; (xv) IBM's acquisition of Tivoli Systems; (xvi) Microtest's acquisition of Hotware; (xvii) Adobe's acquisition of Frame Technology; (xviii) McAfee Associates' acquisition of Saber Software; (xix) Microcom's acquisition of Extension Technology; (xx) Sybase's acquisition of Powersoft; and (xxi) McAfee Associates' acquisition of Brightwork Development. o For these selected mergers and acquisitions, Robinson-Humphrey calculated purchase price as a multiple of book value and firm value as a multiple of latest twelve months revenues. The purchase price to book value multiples ranged from 13.0x to 2.4x, with an average of 7.7x, thus implying a value of $34.68 per share for WGTI. The firm value to latest twelve months revenues multiples ranged from 7.39x to 1.08x, with an average of 3.32x, thus implying a value of $34.47 per share for WGTI. o Robinson-Humphrey also specifically focused on the multiples to book value and latest twelve months revenues for the recent acquisition by McAfee Associates of Network General and the proposed acquisition by Clayton Dubilier of Dynatech. These two acquisitions involved companies (Network General and Dynatech) which are competitors of WGTI. The purchase price to book value multiples for these two transactions ranged from 6.0x to 4.7x, with an average of 5.3x, thus implying a value of $23.90 per share for WGTI. The firm value to latest twelve months revenues multiples ranged from 3.21x to 1.94x, with an average of 2.57x, thus implying a value of $27.07 per share for WGTI. o See attached Exhibit C for the implied valuation averages Robinson-Humphrey used in its analysis. -4- - -------------------------------------------------------------------------------- Summary of Discounted Cash Flow Analysis - -------------------------------------------------------------------------------- o Robinson-Humphrey performed a discounted cash flow analysis using detailed projections developed by the Company for fiscal 1998 through fiscal 2001 as the financial extension of its strategic planning process. It should be noted that WG Holding was actively involved in this process and has approved the validity of these projections. o Robinson-Humphrey calculated a net present value of free cash flows (defined as earnings before interest after taxes plus depreciation and amortization less capital expenditures and any increase in net working capital) for fiscal 1998 through 2002 using discount rates ranging from 15% to 27.5%. Robinson-Humphrey calculated the Company's terminal values in fiscal 2002 based on multiples of fiscal 2002 projected EBIT ranging from 6.0x to 11.0x. o Using a discount rate of 20% and a terminal value multiple of 8.0x fiscal 2002 EBIT, the discounted cash flow analysis provides a valuation of $18.89 per share for WGTI. o See attached Exhibit D for the discounted cash flow analysis Robinson-Humphrey used in its analysis. -5- Exhibit A Page 1 Project TroubleShooter Historical Income Statement Information (In Thousands, Except for Per Share Amounts) Fiscal Year Ended September 30, ----------------------------------------------------------------------------------------------------- 1989 1990 1991 1992 1993 1994 1995 1996 1997 ---- ---- ---- ---- ---- ---- ---- ---- ---- Revenues: Nonaffiliates $ 7,485 $10,421 $11,387 $14,438 $18,005 $21,785 $23,658 $33,186 $29,001 Affiliates 6,881 6,659 9,211 12,768 15,080 18,387 21,604 25,900 25,454 ------- ------- ------- ------- ------- ------- ------- ------- ------- Total Revenues 14,366 17,080 20,598 27,206 33,085 40,172 45,262 59,086 54,455 % Revenue Growth -
