1 EXHIBIT 99.3 UNAUDITED PRO FORMA CONDENSED CONSOLIDATED COMBINED FINANCIAL STATEMENTS INTRODUCTION On December 2, 2023, MACOM Technology Solutions Holdings, Inc. (“MACOM”) completed its acquisition (the “Business Combination”) of the radio frequency business (the “RF Business”) of Wolfspeed, Inc. (the “Seller”) pursuant to an Asset Purchase Agreement (the “Purchase Agreement”) entered into with the Seller on August 22, 2023. The following unaudited pro forma condensed consolidated combined financial information is provided to aid you in your analysis of the financial aspects of the Business Combination. The unaudited pro forma condensed consolidated combined financial statements are based on MACOM’s historical audited consolidated financial statements and the historical combined carve-out financial statements of the RF Business, as adjusted to give effect to the Business Combination and related transactions. The historical financial statements of MACOM were prepared based on a 52- or 53-week fiscal year ending on the Friday closest to the last day of September, which was September 29, 2023 fiscal year-end. The historical financial statements of the RF Business were prepared based on a 52- or 53-week fiscal year ending on the last Sunday in the month of June, which was June 25, 2023 fiscal year-end. Following the consummation of the Business Combination, the RF Business is consolidated into the financial statements of MACOM using the same fiscal year-end as MACOM.

4 NOTES TO THE UNAUDITED PRO FORMA CONDENSED CONSOLIDATED COMBINED FINANCIAL STATEMENTS 1. Description of the Business Combination On December 2, 2023, MACOM completed the acquisition of certain assets and specified liabilities of the RF Business, in accordance with the Purchase Agreement with the Seller, which will be accounted for as a business combination. The RF Business includes a portfolio of GaN on Silicon Carbide products used in high performance radio frequency and microwave applications. As part of the Business Combination, we expect to assume control of a wafer fabrication facility in Research Triangle Park, North Carolina (the “RTP Fab”) approximately two years following the closing of the Business Combination (the “RTP Fab Transfer”). Prior to the RTP Fab Transfer, the Seller will continue to operate the facility and supply wafer product and other fabrication services to us pursuant to various agreements entered into between the parties concurrently with the closing of the Business Combination. In addition, MACOM will lease an identified office space at the RTP Fab until the RTP Fab is conveyed to MACOM. Total purchase consideration for the acquisition of the RF Business consisted of: (i) $75 million in cash; and (ii) 711,528 shares of the MACOM’s common stock, par value of $0.001 per share, with a fair value of $60.8 million at closing of the Business Combination based on the Nasdaq closing price for MACOM’s common stock on December 1, 2023. If the RTP Fab has not transferred to MACOM by the fourth anniversary of the closing date, the Seller will forfeit 25% of the share consideration. The purchase consideration is subject to working capital and other adjustments as provided in the Purchase Agreement. 2. Basis of Pro Forma Presentation The unaudited pro forma condensed consolidated combined financial statements were prepared in accordance with Article 11 of SEC Regulation S-X, as amended by the final rule, Release No. 33-10786, Amendments to Financial Disclosures about Acquired and Disposed Businesses. Release No. 33-10786 replaced the existing pro forma adjustment criteria with simplified requirements to depict the accounting for the transaction (“Transaction Accounting Adjustments”) and present the reasonably estimable synergies and other transaction effects that have occurred or are reasonably expected to occur (“Management’s Adjustments”). Management has elected not to present Management’s Adjustments and only presents Transaction Accounting Adjustments in the unaudited pro forma condensed consolidated combined financial information. The adjustments presented in the unaudited pro forma condensed consolidated combined financial statements have been identified and presented to provide relevant information necessary for an understanding of the combined company after the consummation of the Business Combination. The unaudited pro forma condensed consolidated combined financial statements are based on the MACOM’s historical audited consolidated financial statements and the RF Business’s historical combined carve-out financial statements as adjusted to give effect to the Business Combination. The unaudited pro forma condensed consolidated combined balance sheet as of September 29, 2023 combines the historical balance sheet of MACOM as of September 29, 2023 and the historical combined carve-out balance sheet of the RF Business as of September 24, 2023, on a pro forma basis as if the Business Combination had been consummated on September 29, 2023. The unaudited pro forma condensed consolidated combined statements of operations for the year ended September 29, 2023 give pro forma effect to the Business Combination as if it was completed on October 1, 2022, the beginning of the earliest period presented. The unaudited pro forma condensed consolidated combined statements of operations for the year ended September 29, 2023 combines the historical operations of MACOM for the year ended September 29, 2023 and the historical combined carve-out statements of operations of the RF Business for the year ended June 25, 2023. The unaudited pro forma condensed consolidated combined financial statements were prepared using the acquisition method of accounting with MACOM considered the accounting acquirer of the Seller’s RF Business. Under the acquisition method of accounting, the purchase price is allocated to the underlying assets acquired and liabilities assumed by MACOM based on their respective fair market values. Any excess of total consideration transferred over the fair value of the net assets acquired would be recorded as goodwill in these pro-forma financial statements. Refer below to Note 3, Accounting Treatment for the Business Combination.

5 Management has made significant estimates and assumptions in its determination of the pro forma adjustments. The pro forma adjustments reflecting the Business Combination are based on certain currently available information and certain assumptions and methodologies that management believes are reasonable under the circumstances. The pro forma adjustments, which are described in the accompanying notes, may be revised as additional information becomes available and is evaluated. Therefore, it is likely that the actual adjustments will differ from the pro forma adjustments, and it is possible the difference may be material. Management believes that its assumptions and methodologies provide a reasonable basis for presenting all of the significant effects of the Business Combination based on information available to management at this time and that the pro forma adjustments give appropriate effect to those assumptions and are properly applied in the unaudited pro forma condensed consolidated combined financial statements. The unaudited pro forma condensed consolidated combined financial statements do not give effect to any anticipated synergies, operating efficiencies, tax savings, or cost savings that may be associated with the transaction. MACOM and the Seller have not had any historical trading relationship prior to the transaction. Accordingly, no pro forma adjustments were required to eliminate activities between the companies. 3. Accounting Treatment for the Business Combination MACOM is the legal acquiror of the RF Business. For accounting purposes, the transaction will be accounted for using the acquisition method in accordance with Accounting Standards Codification 805, Business Combinations (“ASC 805”). As such, the RF Business will be treated as the “acquired” company for accounting purposes. This determination is primarily based on the fact that subsequent to the Business Combination, MACOM’s stockholders have a majority of the voting power of the combined company, MACOM controls a majority of the governing body of the combined company, and MACOM’s senior management comprises the majority of the senior management of the combined company upon consummation of the Business Combination. Accordingly, for financial reporting purposes, the assets and liabilities of MACOM were stated at historical carrying values and its consolidated financial statements were presented as the predecessor to the combined company in the historical financial statements following the consummation of the Business Combination. Furthermore, for accounting purposes, the assets and liabilities of the RF Business were recorded at their fair values measured as of the acquisition date, and the excess of total consideration transferred over the fair value of the net assets acquired would be recorded as goodwill in the unaudited pro forma condensed consolidated combined balance sheet. The results of the RF Business will be presented within the consolidated results of MACOM from the date of the Business Combination going forward. 4. Preliminary Estimated Purchase Price and Purchase Price Allocation Because the Business Combination occurred relatively recently, the magnitude of the transaction and there is significant information to be obtained and analyzed, management performed preliminary fair value estimates for the purchase price allocation as of the date of this Current Report on Form 8-K/A. These estimates may change during the allowable measurement period, which is up to the point management obtains and analyzes the information that existed as of the date of the Business Combination necessary to determine the fair values of the assets acquired and liabilities assumed, but in no case to exceed more than one year from the date of the Business Combination. MACOM estimated the preliminary fair value of the RF Business assets and liabilities based on discussions with the Seller’s management, preliminary valuation studies, due diligence, and information presented in the Seller’s public filings. The final purchase price and purchase price allocation may be different than what is presented herein, and such differences could be material. Preliminary Estimated Purchase Price The following table summarizes the preliminary estimate of the purchase consideration (in thousands, except per share amount): Cash purchase consideration 75,000$ Number of shares of MACOM common stock issued at closing 711,528 MACOM closing stock price on acquisition date 85.41$ Equity purchase consideration 60,772 Fair value of total consideration transferred 135,772$

(k) Reflects a pro forma adjustment of approximately $7.2 million of MACOM’s non-recurring estimated transaction costs to be incurred after September 29, 2023 consisting of advisory, legal, accounting and auditing fees and other professional fees.

(e) Reflects a pro-forma adjustment to reduce historical rent expense in connection with the pro-forma adjustment to adjust right-of-use assets and lease liabilities for the operating leases assumed in the Business Combination to measure the lease liabilities at the present value of the remaining lease payments, as if the acquired leases were new leases of MACOM at the acquisition date (see Note 5(i) above). (f) Reflects the pro forma adjustment to record rent expense for the lease of the RTP Fab office space MACOM entered into with the Seller concurrently with the Business Combination (see Note 5(h) above).

(h) The pro forma basic and diluted number of shares presented in the unaudited pro forma condensed consolidated combined statement of operations are based upon the number of the Buyer’s shares issued and outstanding as if the Business Combination occurred on October 1, 2022. The calculation of weighted average shares outstanding for pro forma basic and diluted net income per share assumes that the shares issuable in connection with the Business Combination have been outstanding for the entirety of the period presented. The total number of weighted average common shares outstanding, basic, as adjusted is equal to the total number of weighted average common shares outstanding, diluted, as adjusted as the pro-forma earnings of the combined companies result in net loss, and, therefore, increasing the number of MACOM’s common shares issued to the Seller in connection with the Business Combination would be anti-dilutive. Pro forma weighted average common shares outstanding presented in the unaudited pro forma condensed consolidated combined statement of operations for the year ended September 29, 2023 - basic and diluted are calculated as follows (in thousands): Amortization included in cost of revenue To eliminate historical amortization related to patent and licensing rights (539)$ To record amortization expense for intangible assets acquired 14,883 Total pro-forma adjustment 14,344$ Amortization included in research and development expenses To eliminate historical amortization related to patent and licensing rights (61)$ Amortization included in selling, general and administrative expenses To record amortization expense for intangible assets acquired 3,934$ Weighted average common shares outstanding - basic, as reported 70,801 MACOM common stock issued to Wolfspeed in connection with the Business Combination 712 Total numbers of weighted average common shares outstanding - basic, as adjusted 71,513 Weighted average common shares outstanding - diluted, as reported 71,503 Total numbers of weighted average common shares outstanding - diluted, as adjusted 71,513
