how to write about M&A deals I worked on as an intern on my resume?

I did a 6-month long internship at a boutique where I worked on multiple live deals. However, I'm not sure how to specify my contribution to the deals while ensuring confidentiality where applicable. These are the bullet points on my CV:

• Built a DCF model from scratch for a live buy-side M&A process involving a UK Industry company
• Refined DCF assumptions through market research to support [named company]'s acquisition of [named company]
• Built multiple 3-statement financial models analysing competitors to support [named company]'s acquisition of [named company]

In the first bullet point, the company is completely anonymised as this transaction is not publicly disclosed. Bullet points 2 and 3 publicly name the companies involved, as the deals have been publicly disclosed in both press releases and my bank's website.

Is this okay from a confidentiality standpoint? And is it okay for me to specify my high-level contribution in this way? I'm just a bit paranoid. Thanks.
