ISO IsoPlexis Corporation

As previously disclosed, on December 21, 2022, IsoPlexis Corporation, a Delaware corporation (“IsoPlexis”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Berkeley Lights, Inc., a Delaware corporation (“Berkeley Lights”), and Iceland Merger Sub Inc., a Delaware corporation and a wholly owned subsidiary of Berkeley Lights (“Merger Sub”), pursuant to which, upon the terms and subject to the conditions set forth in the Merger Agreement and in accordance with the Delaware General Corporation Law, Merger Sub will be merged with and into IsoPlexis (the “Merger”), with IsoPlexis surviving the Merger as a wholly owned subsidiary of Berkeley Lights. On February 13, 2023, IsoPlexis filed a definitive proxy statement with the Securities and Exchange Commission (“SEC”) in connection with the proposed Merger (as supplemented on February 16, 2023 and March 2, 2023), which also constitutes a prospectus of Berkeley Lights (the “Joint Proxy Statement/Prospectus”).

Since the initial filing of the Joint Proxy Statement/Prospectus, five complaints have been filed in federal courts in New York and Delaware by purported IsoPlexis stockholders against IsoPlexis and the members of the IsoPlexis board of directors (the “IsoPlexis Board”) in connection with the Merger: Dunbar v. IsoPlexis Corporation., et al., Case No. 1:23-cv-00899 (filed February 2, 2023) (S.D.N.Y.); Cataldi v. IsoPlexis Corporation, et al., Case No. 1:23-cv-00981 (filed February 6, 2023) (S.D.N.Y.); Weiss v. IsoPlexis Corporation, et al., Case No. 1:23-cv-01463 (filed February 22, 2023) (S.D.N.Y.); O’Neill  v. IsoPlexis Corporation, et al., Case No. 1:23-cv-00197-UNA (filed February 22, 2023) (D. Del.); and McDaniels v. IsoPlexis Corporation, et al., Case No. 1:23-cv-01544 (filed February 23, 2023) (S.D.N.Y.). (collectively, the “Stockholder Litigation”). Each of the complaints in the Stockholder Litigation include allegations that, among other things, the registration statement on Form S-4 filed by Berkeley Lights in connection with the proposed merger on January 30, 2023 (the “Initial Form S-4”) and/or the Joint Proxy Statement/Prospectus omitted certain material information in violation of Sections 14(a) and 20(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 14a-9 promulgated under the Exchange Act, rendering such document, as applicable, false and misleading. Additionally, attorneys representing several purported IsoPlexis stockholders and a purported Berkeley Lights stockholder have sent demand letters alleging similar insufficiencies in the disclosures in the Joint Proxy Statement/Prospectus (such letters, the “Demand Letters”, and together with the Stockholder Litigation, the “Litigation Matters”).

The complaints filed in the Stockholder Litigation seek various remedies, which include, among other things: (i) enjoining the defendants from proceeding with the proposed Merger unless and until the defendants disclose certain allegedly material information that was allegedly omitted from the Initial Form S-4 and/or the Joint Proxy Statement/Prospectus; (ii) rescinding the Merger Agreement or any of the terms thereof to the extent already implemented or granting rescissory damages; (iii) awarding the plaintiffs the costs and disbursements of the action, including reasonable attorneys’ and expert fees and expenses; (iv) directing the defendants to account to the plaintiff for all damages suffered as a result of the alleged wrongdoing; (v) declaring that the defendants violated Sections 14(a) and/or 20(a) of the Exchange Act; and (vi) granting such other and further relief as the court may deem just and proper.

IsoPlexis and Berkeley Lights believe that the allegations contained in the Litigation Matters are without merit and that no further disclosures are required to supplement the Joint Proxy Statement/Prospectus under applicable laws. However, in order to avoid the risk of the Litigation Matters delaying or adversely affecting the Merger and to minimize the costs, risks and uncertainties inherent in litigation, and without admitting any liability or wrongdoing, IsoPlexis and Berkeley Lights have determined to voluntarily make the following supplemental disclosures to the Joint Proxy Statement/Prospectus, as described in this Current Report on Form 8-K. Nothing in this Current Report on Form 8-K shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein. To the contrary, IsoPlexis and Berkeley Lights specifically deny all allegations in the Litigation Matters and that any additional disclosure was or is required.

These supplemental disclosures will not change the consideration to be paid to IsoPlexis stockholders in connection with the Merger or the timing of the special meeting of IsoPlexis stockholders (the “Special Meeting”) to be held on March 16, 2023, at 11:00 a.m. (Eastern Time), virtually via the internet at meetnow.global/MXPL9X4. The IsoPlexis Board continues to unanimously recommend that you vote “FOR” the proposals to be voted on at the Special Meeting described in the Proxy Statement.

The following disclosures in this Current Report on Form 8-K supplement the disclosures contained in the Joint Proxy Statement/Prospectus and should be read in conjunction with the disclosures contained in the Joint Proxy Statement/Prospectus, which in turn should be read in its entirety. All page references are to the Joint Proxy Statement/Prospectus, and terms used below, unless otherwise defined, shall have the meanings ascribed to such terms in the Joint Proxy Statement/Prospectus.

The first sentence of the eighth paragraph under the sub-heading “—Selected Publicly Traded Companies Analyses” on page 88 is amended and supplemented as follows (with new text underlined and in bold):

Although the selected companies were used for comparison purposes, none of those companies is directly comparable to IsoPlexis or Berkeley Lights nor, except for the ranges of multiples applied in the selected publicly traded companies analyses described above, were individual multiples derived for the selected companies independently determinative of the results derived from such analyses.

The disclosure in the section entitled “The Merger” under the heading “Opinion of IsoPlexis’ Financial Advisor—Summary of Evercore’s Financial Analyses”, beginning on page 93 of the Joint Proxy Statement/Prospectus, is hereby amended as follows:

The following paragraph on page 93, under the sub-heading “—Discounted Cash Flow Analyses—IsoPlexis—Standalone”, is amended and restated by replacing such paragraph in its entirety with the following (with new text underlined and in bold):

Evercore performed a discounted cash flow analysis of IsoPlexis to calculate the estimated present value of the standalone, unlevered, after-tax free cash flows that IsoPlexis was forecasted to generate during calendar years 2023 through 2031 based on the IsoPlexis forecasts, including the impact of future equity raise based on the Financing Estimates, the cost of stock based compensation of IsoPlexis (which was treated as a cash expense) based on the SBC Estimates and the impact of certain tax attributes of IsoPlexis based on the Tax Attributes Estimates. Evercore calculated terminal values for IsoPlexis by applying perpetuity growth rates of 4.0% to 5.0%, which range was selected based on Evercore’s professional judgment and experience, to a terminal year estimate of the unlevered, after-tax free cash flows that IsoPlexis was forecasted to generate based on the IsoPlexis forecasts. The cash flows and terminal values in each case were then discounted to present value as of December 31, 2022 using discount rates ranging from 17.0% to 19.0%, representing an estimate of IsoPlexis’ weighted average cost of capital, as estimated by Evercore based on its professional judgment and experience and based on the capital asset pricing model, which requires certain company-specific inputs, including debt to equity ratio, debt to total capitalization ratio, pre-tax cost of debt, and levered and unlevered betas, as well as certain financial metrics for the United States financial markets generally. Based on this range of implied enterprise values, IsoPlexis’ estimated net debt of approximately $14 million as of December 31, 2022, and the estimated number of fully diluted outstanding shares of IsoPlexis common stock of approximately 174,800,000 as of December 16, 2022 (including the impact of future equity raise based on the Financing Estimates), in each case as provided to Evercore by IsoPlexis management, this analysis indicated a range of implied equity values per share of IsoPlexis common stock of $1.78 to $2.34, compared to the closing price of IsoPlexis common stock of $0.75 per share on December 20, 2022.

The following paragraph on page 93, under the sub-heading “—Discounted Cash Flow Analyses—Berkeley Lights—Standalone”, is amended and restated by replacing such paragraph in its entirety with the following (with new text underlined and in bold):

Evercore performed a discounted cash flow analysis of Berkeley Lights to calculate the estimated present value of the standalone, unlevered, after-tax free cash flows that Berkeley Lights was forecasted to generate during calendar years 2023 through 2031 based on the IsoPlexis forecasts, including the cost of stock based compensation of Berkeley Lights (which was treated as a cash expense) based on the SBC Estimates and the impact of certain tax attributes of Berkeley Lights based on the Tax Attributes Estimates. Evercore calculated terminal values for Berkeley Lights by applying perpetuity growth rates of 4.0% to 5.0%, which range was selected based on Evercore’s professional judgment and experience, to a terminal year estimate of the unlevered, after-tax free cash flows that Berkeley Lights was forecasted to generate based on the IsoPlexis forecasts. The cash flows and terminal values in each case were then discounted to present value as of December 31, 2022 using discount rates ranging from 17.0% to 19.0%, representing an estimate of Berkeley Lights’ weighted average cost of capital, as estimated by Evercore based on its professional judgment and experience and based on the capital asset pricing model, which requires certain company-specific inputs, including debt to equity ratio, debt to total capitalization ratio, pre-tax cost of debt, and levered and unlevered betas, as well as certain financial metrics for the United States financial markets generally. Based on this range of implied enterprise values, Berkeley Lights’ estimated net debt of approximately negative $111 million as of December 31, 2022, and the estimated number of fully diluted outstanding shares of Berkeley Lights common stock of approximately 77,000,000 as of December 16, 2022, in each case as provided to Evercore by IsoPlexis management, this analysis indicated a range of implied equity values per share of Berkeley Lights common stock of $2.67 to $3.36, compared to the closing price of Berkeley Lights common stock of $2.28 per share on December 20, 2022.

The following paragraph on page 93, under the sub-heading “—Discounted Cash Flow Analyses—Berkeley Lights—Pro Forma”, is amended and restated by replacing such paragraph in its entirety with the following (with new text underlined and in bold):

Evercore performed a discounted cash flow analysis of Berkeley Lights on a pro forma basis giving effect to the merger to calculate the estimated present value of the unlevered, after-tax free cash flows that Berkeley Lights on a pro forma basis giving effect to the merger was forecasted to generate during calendar years 2023 through 2031 based on the IsoPlexis forecasts, taking into account the projected Synergies, and including the cost of stock based compensation of Berkeley Lights on a pro forma basis (which was treated as a cash expense) based on the SBC Estimates and the impact of certain tax attributes of Berkeley Lights on a pro forma basis based on the Tax Attributes Estimates. Evercore calculated terminal values for Berkeley Lights on a pro forma basis by applying perpetuity growth rates of 4.0% to 5.0%, which range was selected based on Evercore’s professional judgment and experience, to a terminal year estimate of the unlevered, after-tax free cash flows that Berkeley Lights on a pro forma basis was forecasted to generate based on the IsoPlexis forecasts. The cash flows and terminal values in each case were then discounted to present value as of December 31, 2022 using discount rates ranging from 17.0% to 19.0%, representing an estimate of the weighted average cost of capital of Berkeley Lights on a pro forma basis, as estimated by Evercore based on its professional judgment and experience and based on the capital asset pricing model, which requires certain company-specific inputs, including debt to equity ratio, debt to total capitalization ratio, pre-tax cost of debt, and levered and unlevered betas, as well as certain financial metrics for the United States financial markets generally. Based on this range of implied enterprise values, the estimated net debt of Berkeley Lights of approximately negative $97 million on a pro forma basis as of December 31, 2022, and the estimated number of fully diluted outstanding shares of Berkeley Lights common stock on a pro forma basis (based on the number of fully diluted outstanding shares of Berkeley Lights common stock of approximately 102,100,000 as of December 16, 2022 plus the estimated number of shares of Berkeley Lights common stock to be issued to holders of shares of IsoPlexis common stock based on the exchange ratio of 0.6120x pursuant to the merger agreement), in each case as provided to Evercore by IsoPlexis management, this analysis indicated (i) an aggregate equity value for Berkeley Lights on a pro forma basis giving effect to the merger (at the mid-point of the perpetuity growth rates and discount rates) of $826 million and (ii) a range of implied equity values per share of Berkeley Lights common stock on a pro forma basis giving effect to the merger of $7.22 to $9.17.

The following paragraph on page 95, under the sub-heading “—Selected Publicly Traded Companies Analysis—IsoPlexis”, is amended and restated by replacing such paragraph in its entirety with the following (with new text underlined and in bold):

Based on the multiples it derived for the selected companies and based on its professional judgment and experience, Evercore applied TEV/2023E Revenue multiple reference ranges of 1.6x to 2.1x to IsoPlexis’ estimated calendar year 2023 revenue, based on the IsoPlexis forecasts, to derive an implied enterprise value reference range for IsoPlexis. Evercore then subtracted IsoPlexis’ estimated net debt of approximately $14 million as of December 31, 2022, and divided by the estimated number of fully diluted outstanding shares of IsoPlexis common stock of approximately 41,400,000 as of December 16, 2022, in each case as provided to Evercore by IsoPlexis management, to calculate a reference range of implied equity values per share of IsoPlexis common stock. This analysis indicated a range of implied equity values per share of IsoPlexis common stock of $0.69 to $1.01, compared to the closing price of IsoPlexis common stock of $0.75 per share on December 20, 2022.

The following paragraph and table on page 96, under the sub-heading “—Precedent Transactions Analysis”, is amended and restated by replacing such paragraph and table in their entirety with the following (with new text underlined and in bold and deleted text marked with a strikethrough):

Evercore reviewed, to the extent publicly available, financial information related to the following selected transactions involving publicly traded target companies in the life sciences tools, diagnostics and medical technology industries.

Based on the multiples it derived for the selected companies and based on its professional judgment and experience, Evercore applied TEV/2023E Revenue multiple reference ranges of 1.6x to 2.1x to Berkeley Lights’ estimated calendar year 2023 revenue, based on the IsoPlexis forecasts, to derive an implied enterprise value reference range for Berkeley Lights. Evercore then subtracted Berkeley Lights’ estimated net debt of approximately negative $111 million as of December 31, 2022, and divided by the estimated number of fully diluted outstanding shares of Berkeley Lights common stock of approximately 76,800,000 as of December 16, 2022, in each case as provided to Evercore by IsoPlexis management, to calculate a reference range of implied equity values per share of Berkeley Lights common stock.

Evercore then subtracted IsoPlexis’ estimated net debt of approximately $14 million as of December 31, 2022, and divided by the estimated number of fully diluted outstanding shares of IsoPlexis common stock of approximately 41,400,000 as of December 16, 2022, in each case as provided to Evercore by IsoPlexis management, to calculate a reference range of implied equity values per share of IsoPlexis common stock. This analysis indicated a range of implied equity values per share of IsoPlexis common stock of $0.80 to $1.27, compared to the closing price of IsoPlexis common stock of $0.75 per share on December 20, 2022.

The following paragraph on page 97, under the sub-heading “—Precedent Transactions Analysis—Berkeley Lights”, is amended and restated by replacing such paragraph in its entirety with the following (with new text underlined and in bold):

Based on the multiples it derived from the selected transactions and based on its professional judgment and experience, Evercore selected a reference range of TEV/LTM Revenue multiples of 2.4x to 3.4x and applied this range of multiples to Berkeley Lights’ estimated calendar year 2022 revenue, based on the IsoPlexis forecasts, to derive an implied enterprise value reference range for Berkeley Lights.

Evercore reviewed selected publicly available share price targets (3 for IsoPlexis common stock and 4 for Berkeley Lights common stock) of research analysts’ estimates known to Evercore as of December 19, 2022, noting that the low and high share price targets ranged from (i) $2.00 to $5.00 for IsoPlexis common stock and (ii) $5.00 to $18.00 for Berkeley Lights common stock. This analysis indicated an implied exchange ratio of 0.333x based on the median of analyst price targets of $3.00 for IsoPlexis and $9.00 for Berkeley Lights, compared to the exchange ratio of 0.6120x pursuant to the merger agreement. Public market trading price targets published by equity research analysts do not necessarily reflect current market trading prices for the shares of IsoPlexis common stock and the shares of Berkeley Lights common stock and these target prices and the analysts’ earnings estimates on which they were based are subject to risk and uncertainties, including factors affecting the financial performance of IsoPlexis, Berkeley Lights and future general industry and market conditions.
