Explanatory Note

On March 20, 2023, the Delaware corporation formerly known as “Graybug Vision, Inc.” completed its previously announced merger transaction in accordance with the terms and conditions of the Agreement and Plan of Merger and Reorganization, dated as of November 21, 2022, as amended on February 10, 2023 (the “Merger Agreement”), by and among Graybug Vision, Inc. (“Graybug”), Camaro Merger Sub, Inc., a wholly owned subsidiary of Graybug (“Merger Sub”), and CalciMedica, Inc. (“CalciMedica”), pursuant to which Merger Sub merged with and into CalciMedica, with CalciMedica surviving the merger as a wholly owned subsidiary of Graybug (the “Merger”). Additionally, on March 20, 2023, the Company changed its name from “Graybug Vision, Inc.” to “CalciMedica, Inc.” (the “Company”). See Item 2.01 for additional information regarding completion of the Merger.

Item 2.01 Completion of Acquisition

As previously disclosed, on November 21, 2022, Graybug, Merger Sub and CalciMedica entered into the Merger Agreement. Upon the terms and subject to the satisfaction (or waiver) of the conditions described in the Merger Agreement, including the approval of the transaction by Graybug’s stockholders, Merger Sub would be merged with and into CalciMedica, with CalciMedica surviving the Merger as a wholly owned subsidiary of Graybug. The Merger intended to qualify as a tax-free reorganization for U.S. federal income tax purposes. In connection with the Merger, certain officers, directors and stockholders of CalciMedica and continuing directors of Graybug entered into lock-up agreements, pursuant to which they accepted certain restrictions on transfers of the shares of the Company for the 180-day period following the effective time of the Merger.

On March 17, 2023, in connection with the transactions contemplated by the Merger Agreement and following a special meeting of Graybug’s stockholders (the “Special Meeting”), Graybug filed an Amended and Restated Certificate of Incorporation (the “Graybug Charter”) (i) effecting a reverse stock split of Graybug’s common stock, par value $0.0001 per share (“Graybug common stock”), at a ratio of 14:1 (the “Reverse Stock Split”) and (ii) allowing for the exculpation of specified executive officers for certain breaches of fiduciary duty. Graybug common stock commenced trading on the Nasdaq Global Market on a post-Reverse Stock Split adjusted basis on March 20, 2023 under the ticker symbol “GRAY.” In connection with the Reverse Stock Split, Graybug obtained a new CUSIP number for Graybug common stock which is 38942Q 202.

On March 20, 2023, Graybug, Merger Sub and CalciMedica consummated the transactions contemplated by the Merger Agreement following the Special Meeting. Pursuant to the Certificate of Merger, filed by Merger Sub, which became effective at 4:03 pm Eastern Time on March 20, 2023 (the “Merger Certificate”), Merger Sub was merged with and into CalciMedica and CalciMedica became a wholly owned subsidiary of the Company. At the effective time of the Merger, each outstanding share of CalciMedica capital stock (after giving effect to the automatic conversion of all shares of CalciMedica preferred stock into shares of CalciMedica common stock (“preferred stock conversion”), the automatic exercise of certain CalciMedica warrants to purchase shares of CalciMedica capital stock in accordance with their terms (the “CalciMedica warrant exercises”), the conversion of CalciMedica convertible promissory notes, as may be amended, into CalciMedica common stock pursuant to their terms (“convertible promissory note conversion”) and the closing of the private placement (as defined below), and excluding any shares held as treasury stock by CalciMedica or held or owned by Graybug or any subsidiary of Graybug or CalciMedica and any dissenting shares) was converted into the right to receive 0.0288 shares

of Graybug common stock, which resulted in the issuance by Graybug of an aggregate of 3,946,538 shares of Graybug common stock to the stockholders of CalciMedica in a transaction exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”) in reliance on Section 4(a)(2) of the Securities Act and the rules promulgated thereunder. In addition, Graybug assumed the CalciMedica 2006 Stock Plan and each outstanding and unexercised option to purchase CalciMedica common stock and each outstanding and unexercised warrant to purchase CalciMedica capital stock (excluding the warrants which were automatically exercised pursuant to the CalciMedica warrant exercises) which became options and warrants to purchase shares of Graybug common stock. In connection with the Merger, Graybug, CalciMedica and Merger Sub waived the condition that the shares of Graybug common stock to be issued in the Merger be approved for listing on Nasdaq as of the Closing and agreed to use reasonable best efforts to file with the Securities and Exchange Commission (“SEC”) a registration statement on Form S-3 registering the resale of shares of Graybug common stock issued to the stockholders of CalciMedica in the Merger and maintain Graybug’s listing on Nasdaq.

The Merger was treated as a reverse recapitalization under U.S. generally accepted accounting principles. CalciMedica is considered the accounting acquirer for financial reporting purposes.

Immediately prior to the consummation of the Merger, CalciMedica completed a private placement financing pursuant to which certain investors purchased approximately 20.7 million shares of CalciMedica common stock for an aggregate purchase price of $10.3 million (the “private placement”). In connection with the private placement, CalciMedica entered into a registration rights agreement with the private placement investors, pursuant to which CalciMedica granted certain registration rights with respect to the shares sold to the private placement investors in the private placement (the “Registration Rights Agreement”).

Immediately prior to the consummation of the Merger, CalciMedica filed a Certificate of Amendment to its Amended and Restated Certificate of Incorporation changing its name from “CalciMedica, Inc.” to “CalciMedica Subsidiary, Inc.” and Graybug filed a Certificate of Amendment (the “Certificate of Amendment”) to the Graybug Charter changing its name from “Graybug Vision, Inc.” to “CalciMedica, Inc.” The Company’s common stock commenced trading on the Nasdaq Global Market under the ticker symbol “CALC” on March 21, 2023.

Following the consummation of the Merger, the business previously conducted by CalciMedica became the business conducted by the Company, which is now a clinical-stage biopharmaceutical company focused on developing therapies for life-threatening inflammatory diseases with high unmet need. The Company’s proprietary technology targets the inhibition of calcium-release activated calcium (“CRAC”) channels designed to modulate the immune response and protect against tissue cell injury, with the potential to provide therapeutic benefits in life-threatening inflammatory diseases for which there are currently no approved therapies. The Company’s lead product candidate Auxora, a proprietary, intravenous-formulated CRAC channel inhibitor, is in development for acute pancreatitis and asparaginase-associated pancreatitis. The Company’s headquarters are located in La Jolla, California (CalciMedica’s former headquarters).

Immediately following the consummation of the Merger, there were 5,517,754 shares of the Company’s common stock issued and outstanding, with prior CalciMedica equityholders collectively owning approximately 72% of the Company and prior Graybug equityholders collectively own approximately 28% of the Company, in each case on a fully diluted basis.

The foregoing descriptions of the Merger Agreement, the Graybug Charter, the Merger Certificate, the Registration Rights Agreement and the Certificate of Amendment do not constitute a complete summary of the terms of the Merger Agreement, the Graybug Charter, the Merger Certificate, the Registration Rights Agreement or the Certificate of Amendment, and are qualified in their entirety by reference to the full text of the Merger Agreement, the Graybug Charter, the Merger Certificate, the Registration Rights Agreement and the Certificate of Amendment, copies of which are attached to this Current Report on Form 8-K as Exhibits 2.1, 3.1, 3.3, 4.1 and 3.2 hereto and are incorporated herein by reference.

As a result of the Reverse Stock Split, the number of issued and outstanding shares of Graybug common stock immediately prior to the Reverse Stock Split was reduced into a smaller number of shares, such that every 14 shares of Graybug common stock held by a stockholder immediately prior to the Reverse Stock Split were combined and reclassified into one share of Graybug common stock after the Reverse Stock Split.

No fractional shares were issued in connection with the Reverse Stock Split. In accordance with the Graybug Charter, each stockholder who would otherwise be entitled to a fraction of a share of Graybug common stock upon the consummation of the Reverse Stock Split (after taking into account all fractional shares of Graybug common stock otherwise issuable to such holder) shall, in lieu thereof, be entitled to receive a cash payment in an amount equal to the fractional shares to which the stockholder would otherwise be entitled multiplied by $0.4961, the closing price of Graybug common stock on the Nasdaq Global Market on the date immediately preceding the effective time of the Reverse Stock Split (as adjusted to give effect to the Reverse Stock Split).

In accordance with the Graybug Charter, no corresponding adjustment was made with respect to Graybug’s authorized Graybug common stock or Graybug preferred stock. The Reverse Stock Split has no effect on the par value of the Graybug common stock or Graybug preferred stock. Immediately after the Reverse Stock Split and prior to the closing of the Merger, each stockholder’s percentage ownership interest in Graybug and proportional voting power remained unchanged, other than as a result of the rounding to eliminate fractional shares, as described in the preceding paragraph. The rights and privileges of the holders of shares of Graybug common stock were unaffected by the Reverse Stock Split.

The foregoing description of the Graybug Charter not complete and is subject to and qualified in its entirety by reference to the Graybug Charter, a copy of which is attached as Exhibit 3.1 to this Current Report on Form 8-K and is incorporated herein by reference.

In addition, as previously disclosed, on February 28, 2023, the board of directors of Graybug terminated Parisa Zamiri’s employment in advance of the anticipated closing date of the Merger.

Acceleration of Restricted Stock Units and Options; Amendments to Award Agreements

Upon the involuntary, without “cause” termination of the employment of Fred Guerard, PharmD., Robert S. Breuil and Parisa Zamiri (each an “Executive” and together the “Executives”) in connection with the closing of the Merger (in Dr. Zamiri’s case, upon her earlier termination of employment prior to closing), outstanding stock option (“Options”) and restricted stock units (“RSUs”) for Graybug common stock held by the Executives were accelerated in full pursuant to the terms of Graybug’s existing Change in Control Severance Policy. The severance benefits and vesting acceleration provided under the Change in Control Severance Policy to Dr. Guerard, Mr. Breuil and Dr. Zamiri are described in Graybug’s definitive proxy statement on Schedule 14A filed with the SEC on February 9, 2023 (the “Proxy Statement”) and are qualified in their entirety by reference to the full text of the Change in Control Severance Policy, which was filed as Exhibit 10.11 to Graybug’s registration statement filed with the SEC on Form S-1 on September 4, 2020.

On March 19, 2023, the board of directors of Graybug approved, and prior to closing of the Merger the Executives and Graybug entered into, amendments to the award agreements governing outstanding Options and RSUs held by each of the Executives (for each Executive, an “Option Amendment Agreement” and a “RSU Amendment Agreement”). Each Option Amendment Agreement extends the period of time during which the Executive party thereto may exercise those Options that they hold having an exercise price less than or equal to $1.33 per share (prior to adjustment to reflect a stock split occurring on or prior to March 20, 2023) through to March 1, 2024 as set forth in, and qualified in its entirety by reference to, the full text of the form of Option Amendment Agreement, a copy of which is attached as Exhibit 10.12 to this Current Report on Form 8-K and is incorporated herein by reference. Each RSU Amendment Agreement provides that, to the greatest extent possible and subject to certain conditions and limitations, those vested RSUs held by the Executives will be settled using “net-settlement” (i.e., withholding from shares to be issued upon settlement of the RSUs), as set forth in, and qualified in its entirety by reference to, the full text of the form of RSU Amendment Agreement, a copy of which is attached as Exhibit 10.13 to this Current Report on Form 8-K and is incorporated herein by reference. Except as set forth in the Option Amendment Agreements and the RSU Amendment Agreements, the provisions of the existing award agreements governing those Options and those RSUs held by the Executives continue to remain in full force and effect.

The 2022 Notes accrued interest at a rate of 6% per annum and had a maturity date of December 31, 2023. Immediately prior to the effective time of the Merger, the 2022 Notes converted into shares of CalciMedica common stock at a conversion price based on the equivalent valuation of the cash price paid per share by the private placement investors purchasing shares of CalciMedica common stock in the private placement multiplied by 0.85.
