In connection with the closing of the Business Combination on May 23, 2023 (the “Closing”), ROCG changed its name to “Tigo Energy, Inc.”

CUSIP No. 88675P103

SCHEDULE 13D

Page 6 of 10 Pages

Prior to the Business Combination, EGM II LP directly held (i) 32,334,554 shares of Legacy Tigo’s Series D convertible preferred stock (“Series D preferred stock”), which it acquired in January and February of 2021 for a purchase price of $0.4369 per share using its working capital, (ii) 4,423,401 shares of Legacy Tigo’s Series E convertible preferred stock (“Series E preferred stock”), which it acquired in May of 2022, for a purchase price of $1.2208 per share using its working capital, and (iii) an option to purchase up to 40,000 shares of Legacy Tigo’s common stock at an exercise price of $0.60 per share, which was granted to EGM II LP on June 23, 2022. Prior to the Business Combination, Tigo SPV directly held 20,952,280 shares of Legacy Tigo’s Series E preferred stock, which it acquired in June and July of 2022, for a purchase price of $1.2208 per share using its working capital.

Under the terms of the Merger Agreement, immediately prior to the effective time of the Business Combination (the “Effective Time”), Legacy Tigo (i) caused each share of Legacy Tigo preferred stock issued and outstanding to be automatically converted into a number of shares of Legacy Tigo common stock (the “Legacy Tigo common stock”) in accordance with Legacy Tigo’s charter (the “preferred stock conversion”).

Pursuant to the Merger Agreement, at the Effective Time, each share of Legacy Tigo common stock issued and outstanding immediately prior to the Closing were cancelled and converted into the right to receive 0.233335 shares of Common Stock. Also at the Effective Time, each outstanding Legacy Tigo stock option (each, a “Legacy Tigo stock option”), whether vested or unvested, converted into an option to purchase a number of shares of Common Stock equal to the product of (x) the number of shares of Legacy Tigo common stock underlying such Legacy Tigo stock option immediately prior to closing and (y) 0.233335, at an exercise price per share equal to (A) the exercise price per share of Legacy Tigo common stock underlying such Legacy Tigo stock option immediately prior to the Closing divided by (B) 0.233335.

Accordingly, under the terms of the Merger Agreement, immediately prior to the Effective Time, the 32,334,552 shares of Legacy Tigo’s Series D preferred stock and 4,423,401 shares of Series E preferred stock, each held directly by EGM II LP, and the 20,952,280 shares of Legacy Tigo’s Series E preferred stock held directly by Tigo SPV, was converted into Legacy Tigo common stock and, at the Effective Time, EGM II LP acquired (i) 9,133,224 shares of Common Stock in exchange for its Legacy Tigo’s common stock and (ii) an option to purchase 9,333 shares of Common Stock at an exercise price of $2.57 per share (the “Stock Option”), in exchange for its Legacy Tigo stock option, and Tigo SPV acquired 5,208,625 shares of Common Stock in exchange for its Legacy Tigo common stock. The Stock Option vests 25% on June 23, 2023, and the remainder in 1/48th monthly installments over the following thirty-six months.
