(Reuters) -Aerospace supplier TransDigm Group on Thursday forecast its annual profit and revenue below analysts' expectations and highlighted risks around the pace of commercial jetliner production as the industry battles persistent supply shortages.

Shares of the company, which supplies aircraft components such as cockpit security systems and engine sensors for commercial and military jets, were down 4.5%.

The company said it had initiated cost reduction measures such as furloughs and headcount reductions in recent weeks.

While TransDigm has predominantly benefited from booming demand for repairs on older jets in recent quarters, it also sells parts for new jets to planemakers Boeing and Airbus.

Boeing is working to emerge from a recent crisis after a near two-month walkout by about 33,000 workers halted production of most of its jets, with uncertainty prevailing on the company's production targets in 2025. Its rival Airbus continues to struggle with its own parts pressures.

"The lingering effects of the recently resolved Boeing strike has pushed OEM recovery further to the right," a company executive said on a post-earnings call.

TransDigm expects the rise in sales to jet makers in 2025 to be slower than that in its aftermarket business.

"The commercial OEM guidance contains an appropriate level of risk around the expected OEM production build rates for fiscal 2025," it said in a statement.

The Ohio-based supplier expects its fiscal 2025 adjusted profit per share to be between $35.36 and $37.28, compared with analysts' average estimate of $39.01, according to data compiled by LSEG.

It also forecast annual sales of $8.75 billion to $8.95 billion, the midpoint of which is below expectations of $8.92 billion.

For the fourth quarter, it posted an adjusted per-share profit of $9.83, above analysts' expectations of $9.29.

Net Sales for the quarter through Sept. 30 jumped 18% to $2.19 billion, edging past estimates of $2.17 billion.
