Research Alert: CFRA Maintains Hold Rating On Shares Of United Rentals Inc.
CFRA, an independent research provider, has providedwith the following research alert. Analysts at CFRA have summarized their opinion as follows:We lift our 12-month target price to $1,100 from $950 following a strong first quarter, valuing shares at 20.5x our 2027 EPS outlook of $54.28 (in line with previous estimate; 2026 EPS also in line). We believe a higher multiple is justified given URI's firming market leadership within an expanding rental equipment industry. A robust Q1 beat enabled URI to raise its full-year revenue guidance to $16.9B-$17.4B and adjusted EBITDA to $7.625B-$7.875B, citing momentum heading into a busy season. With leverage well below historical levels, we believe accretive M&A deals could serve as a potential catalyst for additional guidance increases. Margin compression has been a sticky issue for URI, but Q1 indicated that pricing may have turned around and that headwinds are starting to ease as quarterly results begin to lap when tariff-related inflation began to pick-up. We remain cautious on margins, though are encouraged by signs of stabilization. New project activity is likely supporting pricing trends, in our view.

Research Alert: CFRA Keeps Buy Opinion On Shares Of The Hartford Insurance Group, Inc.
CFRA, an independent research provider, has providedwith the following research alert. Analysts at CFRA have summarized their opinion as follows:We trim our 12-month target price by $8 to $155, valuing HIG shares at 11.3x our 2026 operating EPS estimate of $13.75 (cut by $0.45) and at 10.6x our 2027 EPS estimate of $14.65 (cut by $0.30), vs. the shares' one-year average forward multiple of 10.3x and peer average of 13x. Q1 EPS of $3.09 vs. $2.20 a year ago missed our $3.60 estimate and $3.39 consensus view. Operating revenue growth of 6.2% was in line with our 6%-10% forecast, amid 5.3% earned premium growth, 13% higher net investment income, and 7.9% fee revenue growth. Q1 written premium growth of 4% and full-year 2025 growth of 7% bode well for 2026 revenue trends as premiums are earned. Underwriting results improved significantly, with Personal Lines combined ratio improving to 87.7% from 106.1% and underlying combined ratio to 85.0% from 89.7%. Business Insurance combined ratio was stable at 94.8%. Weighing the Q1 EPS miss with HIG's decent top-line growth and discounted valuation to peers, we view the shares as undervalued.
