Syros and Tyme Technologies Announce Stockholder Approval of Merger

— Combined Company to Trade on Nasdaq Under Ticker “SYRS” —

— Syros Announces 1-for-10 Reverse Stock Split of Common Stock —

CAMBRIDGE, Mass. & BEDMINSTER, N.J., Sept. 15, 2022 – Syros Pharmaceuticals, Inc. (NASDAQ:SYRS), a leader in the development of medicines that control the expression of genes, and Tyme Technologies, Inc. (NASDAQ:TYME) today announced the results of the special meetings of the stockholders of Syros and TYME, respectively, each held on September 15, 2022. At TYME’s special meeting, TYME’s stockholders voted in favor of all proposals, including the proposal to adopt the agreement and plan of merger, dated July 3, 2022 (the “Merger Agreement”), pursuant to which a direct, wholly owned subsidiary of Syros will merge with and into TYME, with TYME surviving as a wholly owned subsidiary of Syros (the “Merger”). At Syros’ special meeting, Syros’ stockholders also voted in favor of all proposals, including the proposal to approve the issuance of shares of Syros’ common stock to holders of TYME’s common stock in connection with the Merger and to certain of Syros’ investors in connection with a concurrent private investment in public equity (“PIPE”) financing.

The closings of the Merger and the PIPE financing are anticipated to take place on or around Friday, September 16, 2022. Following the closing of the Merger, the combined company will trade on The Nasdaq Global Select Market under the ticker symbol “SYRS,” and will be led by Syros’ existing management team, including Nancy Simonian, M.D., Chief Executive Officer of Syros, and will remain focused on advancing Syros’ pipeline of small molecule medicines for the treatment of cancer.

In addition, Syros today announced that it will effect a 1-for-10 reverse stock split of its common stock that will be effective on Friday, September 16, 2022, prior to the closings of the Merger and the PIPE financing. Syros’ common stock will begin trading on Nasdaq on a split-adjusted basis when the market opens on Monday, September 19, 2022. The new CUSIP number for Syros’ common stock following the reverse stock split is 87184Q206.

On September 15, 2022, the holders of a majority of Syros’ outstanding shares of common stock also approved the reverse stock split and gave Syros’ board of directors discretionary authority to select a ratio for the split ranging from 1-for-5 to 1-for-15. Syros’ board of directors approved the reverse stock split at a ratio of 1-for-10 on September 15, 2022.

The reverse stock split affects all issued and outstanding shares of Syros common stock, as well as the number of authorized shares of Syros common stock and the number of shares of common stock available for issuance under Syros’ equity incentive plans. The reverse stock split will reduce the number of shares of the Syros issued and outstanding common stock from approximately 63 million to approximately 6.3 million (which numbers do not give effect to the shares of Syros common stock to be issued in connection with the Merger and the PIPE financing). In addition, the reverse stock split will effect a reduction in the number of shares of common stock issuable upon the exercise of stock options and warrants and upon the vesting of restricted stock units outstanding immediately prior to the reverse stock split, with a proportional increase in the respective exercise prices. The reverse stock split will proportionately reduce the number of authorized shares of Syros’ common stock from 700 million shares (which is the number of authorized shares that will be outstanding immediately prior to the reverse stock split, in connection with Syros’ receipt of the approval of its stockholders to increase the number of authorized shares from 200 million to 700 million) to 70 million shares. The reverse stock split will not change the par value of the common stock or the authorized number of shares of preferred stock of Syros.

The reverse stock split will affect all holders of common stock uniformly and (before giving effect to the shares of Syros common stock to be issued in connection with the Merger and the PIPE financing) will not alter any stockholder’s percentage ownership interest in Syros, except to the extent that the reverse stock split would result in a stockholder owning a fractional share. No fractional shares of common stock will be issued in connection with the reverse stock split; stockholders who otherwise would be entitled to a fractional share of common stock will be entitled to receive a proportional cash payment.

Syros’ transfer agent, Computershare, is acting as the exchange agent for the reverse stock split. For those stockholders holding physical stock certificates, Computershare will send instructions for exchanging those certificates for shares held in book-entry form representing the post-split number of shares. Stockholders holding their shares in book-entry form or in brokerage accounts need not take any action in connection with the reverse stock split. Beneficial holders are encouraged to contact their bank, broker or custodian with any procedural questions.

About Tyme Technologies, Inc.

TYME is an emerging biotechnology company developing cancer metabolism-based therapies (CMBTs^™) that are intended to be effective across a broad range of solid tumors and hematologic cancers, while also maintaining patients’ quality of life through relatively low toxicity profiles. Unlike targeted therapies that attempt to regulate specific mutations within cancer, TYME’s therapeutic approach is designed to take advantage of a cancer cell’s innate metabolic weaknesses to cause cancer cell death.

TYME is currently focused on developing its novel compound, SM-88 and its preclinical pipeline of novel CMBT^™ programs. TYME believes that early clinical results demonstrated by SM-88 in multiple advanced cancers, including prostate, sarcomas and breast, reinforce the potential of its emerging CMBT^™ pipeline.
