Shares of HealthSouth ( (HLS) ) jumped 7% on Wednesday after the post-acute healthcare services provider reported a strong first quarter and raised full-year guidance. Analysts believe the company is starting to benefit from recent acquisitions. 

"The company appears to be solidly back on track after a 2015 that we described as 'un-HealthSouth-like,'" wrote Barclays analyst Joshua Raskin, who has an equal weight rating on the stock, in a Wednesday note.

The Birmingham, Ala.-based provider of facility-based and home-based post-acute services reported a 23.1% rise in adjusted Ebitda to $192.1 million, beating the consensus of $188.6 million.

"We believe the beat versus consensus was driven by stronger-than-expected admissions in home health and contribution from the Reliant and CareSouth acquisitions," wrote JMP Securities analyst Peter Martin, who has a market outperform rating on the stock, in a note.

HealthSouth completed its acquisition of the operations of Reliant Hospital Partners LLC and affiliated entities for approximately $730 million in October of last year.  HealthSouth's Encompass Home Health operating unit completed its $170 million purchase of the home health and hospice agency operations of CareSouth Health System in November.

In the first three months of 2016, HealthSouth had net operating revenues of $909.8 million, up 22.8% from the year-ago period.

The company's home health and hospice segment had revenue of $160.6 million, up 45.6% year over year, and the inpatient rehabilitation segment had revenue of $749.2 million, up 18.9%.

HealthSouth increased its full-year 2016 guidance for net operating revenues of $3.58 billion to $3.68 billion, versus previous guidance of $3.55 billion to $3.65 billion.  The company expects adjusted Ebitda of $770 million to $790 million, compared with the previous outlook of $765 million to $785 million. It expects adjusted earnings per share from continuing operations attributable to HealthSouth of $2.37 to $2.49, compared with initial guidance of $2.32 to $2.44.
