Filing notes and footnotes

Explanation of responses 5 footnotes

Footnote F1

TCW Strategic Income Fund, Inc. (NYSE: TSI) (the "Fund") issued to the stockholders of record (the "Record Date Stockholders") at the close of business on February 19, 2026 (the "Record Date") transferable rights (each a "Right" and, collectively, the "Rights") entitling such Record Date Stockholders to subscribe for shares of common stock, par value $0.01 per share (the "Common Stock"), of the Fund (the "Offer") at a discount to the market price of the shares of Common Stock. The Fund distributed to Record Date Stockholders one Right for each share of Common Stock held on the Record Date.

Footnote F2

(Continued from footnote 1) Record Date Stockholders were entitled to purchase one new share of Common Stock for every three Rights held (1-for-3); however, any Record Date Stockholder who owned fewer than three shares of Common Stock as of the Record Date was entitled to subscribe for one share of Common Stock. Fractional shares of Common Stock were not issued. The subscription period commenced on the Record Date and expired on March 18, 2026.

Footnote F3

The final subscription price of $4.47 per share of Common Stock was determined based upon the terms of the Offer. Record Date Stockholders who exercised all of their primary subscription Rights (other than those Rights to acquire less than one share of Common Stock that could not be exercised) were eligible for an over-subscription privilege entitling Record Date Stockholders to subscribe for additional shares of Common Stock not purchased pursuant to the primary subscription. The Offer was over-subscribed. The over-subscription requests exceeded the over-subscription shares of Common Stock available.

Footnote F4

(Continued from footnote 3) Accordingly, the shares of Common Stock subscribed for pursuant to the over-subscription privilege of the Offer were allocated pro rata among those fully exercising record date shareholders who over-subscribed based on the number of shares of Common Stock they owned on Record Date. The number of share Common Stock acquired was confirmed to exercising Rights holders on March 27, 2026, following the pro-ration and allocation of shares of Common Stock pursuant to the over-subscription privilege.

Footnote F5

In connection with the Offer, the Reporting Person exercised 307,915 Rights to acquire 102,638 shares of Common Stock, and received an additional 91,123 shares of Common stock pursuant to the over-subscription privilege. In total, the Reporting Person acquired 193,761 shares of Common Stock in connection with the Offer.
