Insider purchases (SEC Form 4, open-market, last ~7 months) (TSLX)

1 purchase, $142K. Private placements, offerings, dividend reinvestment and employee stock purchase plan buys are excluded.

Insider type follows Cohen, Malloy & Pomorski (Journal of Finance, 2012). An insider who traded the stock in the same calendar month in each of the past three years is a routine trader; one who traded in each of those years without such a pattern is an opportunistic trader. In their study, trades by opportunistic insiders predicted future returns and trades by routine insiders did not. Counts open-market purchases and sales only (SEC Form 4 codes P and S) by that insider in that company. Not investment advice.

From Sixth Street Specialty Lending, Inc.'s Latest SEC 10-K Filing (filed 2026-02-12)

Key Strengths & Strategy (as disclosed to the SEC)

• Since we began our investment activities in July 2011, through December 31, 2025, we have originated approximately $53.3 billion aggregate principal amount of investments and retained approximately $11.8 billion aggregate principal amount of these investments on our balance sheet prior to any subsequent exits and repayments.
• On May 6, 2025, we, the Adviser and certain of our affiliates were granted an exemptive order from the SEC that allows us to co-invest, subject to certain conditions, with certain of our affiliates (including affiliates of Sixth Street) in middle-market loan origination activities for companies domiciled in the United States.
• We expect that with the ability to co-invest with Sixth Street affiliates we will continue to be able to provide "one-stop" financing to a potential portfolio company in these circumstances, which may allow us to capture opportunities where we alone could not commit the full amount of required capital or would have to spend additional time to locate unaffiliated co-investors.
• Within our portfolio, we aim to maintain the appropriate proportion among the various types of first-lien loans, as well as second-lien debt and mezzanine debt, which allows us to achieve our target returns while maintaining our targeted amount of credit risk.

Partnerships

• On April 15, 2011, we entered into the Investment Advisory Agreement with our Adviser.
• On March 15, 2011, we entered into the Administration Agreement with our Adviser.

Legal & Regulatory Risks (Item 1A, quoted)

• Changes in tax laws may adversely affect our business.
• Failure or alleged failure to comply with applicable data protection and privacy laws and regulations could subject us to ongoing costs and, in some cases, fines and reputational harm.
• Trade negotiations and related government actions may create global supply chain issues and regulatory uncertainty for our portfolio companies and our investment strategy and adversely affect the profitability of our portfolio companies.
• Changes in laws or regulations governing our operations may adversely affect our business.
