Exhibit 99.6

Subject: Morphic Enters into Agreement to be Acquired by Lilly

Dear NAME,

This morning, we announced that we have entered into an agreement to be acquired by Eli Lilly and Company (“Lilly”) (NYSE: LLY), in an all-cash transaction valued at approximately $3.2 billion. Under the terms of the agreement, Morphic shareholders will receive $57.00 in cash for each share of Morphic they own. The press release announcing this news can be found here [INSERT LINK].

Following careful consideration with the assistance of external financial and legal advisors, our Board determined that the transaction with Lilly is in the best interest of Morphic and its shareholders. The purchase price represents a premium of 79.0% to Morphic’s closing share price of $31.84 on July 5, 2024 and a premium of 87.2% to Morphic’s 30-trading-day volume weighted average price as of July 5, 2024, the last trading day before the announcement of the transaction.

Morphic believes – and has stated – that the patient impact of MORF-057 could be significantly enhanced by the partnership with a global medicines company. We are confident we have found that partner in Lilly, a globally recognized medicines company committed to improving patient health. In addition to creating shareholder value, we believe that the transaction will deliver benefits for patients – as Lilly’s scale, resources, global footprint and approval track record will help advance MORF-057 and our integrin discovery platform beyond what we could as a standalone company.

The transaction with Lilly is expected to close in the third quarter of 2024, subject to the satisfaction of customary closing conditions.

This is an exciting milestone for Morphic, and we look forward to completing it and providing value for our shareholders.

Thank you for your support.

Sincerely,

NAME

TITLE

Cautionary Notice Regarding Forward-Looking Statements

This communication contains “forward-looking statements” relating to the proposed acquisition of Morphic Holding, Inc., a Delaware corporation (the “Company”), by Eli Lilly and Company, an Indiana corporation (“Parent”). Such forward-looking statements include, but are not limited to, the ability of the Company and Parent to complete the transactions contemplated by the Agreement and Plan of Merger, dated July 7, 2024, between Parent, the Company and Rainier Acquisition Corporation, a Delaware corporation (“Purchaser”) and wholly-owned subsidiary of Parent (the “Merger Agreement”), including the parties’ ability to satisfy the conditions to the consummation of the tender offer (the “offer”) contemplated thereby and the other conditions set forth in the Merger Agreement, statements about the expected timetable for completing the transaction, the Company’s and Parent’s beliefs and

expectations and statements about the benefits sought to be achieved by Parent’s proposed acquisition of the Company, the potential effects of the acquisition on both the Company and Parent, and the possibility of any termination of the Merger Agreement. In some cases, forward-looking statements may be identified by terminology such as “believe,” “may,” “will,” “should”, “predict”, “goal”, “strategy”, “potentially,” “estimate,” “continue,” “anticipate,” “intend,” “could,” “would,” “project,” “plan,” “expect,” “seek” and similar expressions and variations thereof. These words are intended to identify forward-looking statements. The Company has based these forward-looking statements on current expectations and projections about future events and trends that it believes may affect the financial condition, results of operations, business strategy, short-term and long-term business operations and objectives and financial needs of the Company, but there can be no guarantee that such expectations and projections will prove accurate in the future.

All statements other than statements of historical fact are statements that could be deemed forward-looking statements. Actual results may differ materially from current expectations because of risks associated with uncertainties as to the timing of the offer and the subsequent merger; uncertainties as to how many of the Company’s stockholders will tender their shares in the offer; the risk that competing offers or acquisition proposals will be made; the possibility that various conditions to the consummation of the merger and the offer contemplated thereby may not be satisfied or waived; the effects of disruption from the transactions contemplated by the Merger Agreement on the Company’s business and the fact that the announcement and pendency of the transactions may make it more difficult to establish or maintain relationships with employees, suppliers and other business partners; and the risk that stockholder litigation in connection with the offer or the merger may result in significant costs of defense, indemnification and liability. Moreover, the Company operates in a very competitive and rapidly changing environment, and new risks emerge from time to time. Although the Company believes that the expectations reflected in such forward-looking statements are reasonable, it cannot guarantee future events, results, actions, levels of activity, performance or achievements, business and market conditions, the timing and results of any developments and whether the conditions to the closing of the proposed acquisition are satisfied on the expected timetable or at all. Additional factors that may affect the future results of Parent and the Company are set forth in their respective filings with the U.S. Securities and Exchange Commission (the “SEC”), including in each of Parent’s and the Company’s most recently filed Annual Report on Form 10-K, subsequent Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other filings with the SEC, which are available on the SEC’s website at www.sec.gov. The risks described in this communication and in Parent’s and the Company’s filings with the SEC should be carefully reviewed. Undue reliance should not be placed on these forward-looking statements, which speak only as of the date they are made. Parent and the Company undertake no obligation to publicly release any revisions to the forward-looking statements after the date hereof to conform these statements to actual results or revised expectations.
