Accelerant Holdings (ARX) Soars 57% as Buyer Bets Big on Firm
Accelerant Holdings (NYSE:ARX) shares rose about 57% after Thoma Bravo agreed to acquire the company for $4 billion. The offer price is $20.25 per share, a 49% premium to the prior close. ARX said shareholders may receive a 6% annual ticking fee if regulatory approvals delay closing, expected in H1.
How this was made

The 30-second read
Why it matters
The disclosed offer price, premium, and ticking-fee clause create a clear catalyst for deal-spread trading, while the first-half closing timeline makes regulatory approval timing a near-term driver.
Market read
A disclosed all-cash style acquisition price with a premium and delay compensation is a direct, tradable catalyst for ARX and deal-arb positioning.
What to watch
The article does not quantify regulatory approval risk or shareholder vote thresholds, which are key determinants of deal-spread compression versus widening.
Background
ARX is set to become private after Thoma Bravo’s $4 billion acquisition, following strong Q2 results.
Ticker impact
Accelerant Holdings agreed to be acquired for $4 billion by Thoma Bravo, with a $20.25 offer price and a 6% ticking fee if approvals delay closing.

The article discloses a specific acquisition price, premium, and delay compensation, plus expected timing in the first half of the year, all of which directly affect deal-spread and closing odds.
Market effects

Primarily US-listed deal dynamics, with limited direct regional spillover mentioned.
Thoma Bravo’s software-focused strategy may reinforce cross-border interest in insurance tech assets, but no global specifics are provided.
