Stoneridge Reports First-Quarter 2021 Results

STRONG FIRST QUARTER PERFORMANCE DESPITE EXTERNAL HEADWINDS

2021 First-Quarter Results

2021 Full-year Guidance Update

NOVI, Mich. – April 28, 2021 – Stoneridge, Inc. (NYSE: SRI) today announced financial results for the first quarter ended March 31, 2021, with sales of $193.8 million and earnings per diluted share (EPS) of $0.00. Adjusted sales were $192.8 million and adjusted EPS was $0.06 for the first quarter, considering normalizing adjustments primarily related to the gain on the disposal of the assets of the soot sensor business divestiture, fair value adjustments and restructuring expenses. The exhibits attached hereto provide additional detail on the normalizing adjustments.

For the first quarter of 2021, Stoneridge reported gross profit of $46.1 million and adjusted gross profit of $46.7 million (24.2% of sales). Operating income was $2.1 million and adjusted operating income was $3.6 million (1.8% of sales). Adjusted EBITDA was $12.2 million (6.3% of sales).

Jon DeGaynor, president and chief executive officer, commented, “In the first quarter we delivered strong financial performance and exceeded our previously outlined expectations from both a revenue and earnings perspective. Most importantly, we achieved our operating objectives with strong operational efficiency and reduced controllable costs. However, similar to companies in our industry and around the world, we incurred incremental costs related to global supply chain disruptions which reduced our adjusted operating income by $2.7 million, or more than 40%, in the quarter. We will continue to execute on the things that we can control as we respond efficiently and effectively to the macroeconomic environment.”

DeGaynor continued, “During the quarter, we continued the transformation of the company by finalizing an agreement to divest our soot sensor business, which is yet another transaction that will allow us to focus our resources on the technology platforms that will drive future growth. We continue to expand our MirrorEye® platform, as we prepare for our first OEM launches in the second half of 2021 and expand our retrofit programs. During the quarter, we announced that two fleets, Maverick and Montgomery, intend to install MirrorEye® on 100% of their new trucks. In addition, we are excited to announce our partnership with PACCAR with the launch of our digital instrument cluster on their recently introduced heavy- and medium-duty trucks.”

First Quarter in Review

Control Devices adjusted sales, excluding the impact of the recently divested soot sensor business, totaled $97.6 million, a decrease of $0.3 million relative to the fourth quarter of 2020. First quarter adjusted operating margin, excluding the impact of the recently divested business, was 11.1%, a decrease of 140 basis points relative to the fourth quarter of 2020 primarily due to incremental costs related to supply chain related issues impacting gross margin.

Electronics sales totaled $88.7 million, an increase of $4.7 million relative to the fourth quarter of 2020 primarily due to increased sales in the off-highway end market as well as a favorable foreign currency impact of $1.0 million. First quarter adjusted operating margin was (0.7%), which was a decrease of 590 basis points relative to the fourth quarter of 2020 primarily driven by increased material and expediting costs as a result of supply chain disruptions, unfavorable product mix and incremental investment in engineering resources.

Stoneridge Brazil sales of $11.4 million decreased by $1.9 million relative to the fourth quarter of 2020 due to challenging macroeconomic conditions reducing demand in local end markets and unfavorable foreign currency impact of ($0.2 million). Stoneridge Brazil adjusted operating margin decreased by 90 basis points relative to the fourth quarter of 2020 primarily due to lower SG&A cost leverage from reduced sales offset by higher gross margin by 200 basis points.

Cash and Debt Balances

As of March 31, 2021, Stoneridge had cash and cash equivalents balances totaling $60.5 million. Total debt as of March 31, 2021 was $158.7 million. Total debt less cash and cash equivalents yielded a current net debt to trailing-twelve-month adjusted EBITDA ratio of approximately 2.9x. The Company expects to return to a more normalized net debt to trailing-twelve month adjusted EBITDA ratio of less than 2.0x by the end of 2021.

2021 Outlook

Bob Krakowiak, chief financial officer, commented, “We are maintaining our previously provided revenue guidance primarily due to first quarter outperformance and our expectation that our product portfolio will continue to outperform the underlying market, offsetting full-year forecasted production headwinds. Additionally, due to expected externalities and forecasted unfavorable product mix, partially offset by outperformance in the first quarter, we are reducing our full-year adjusted EPS guidance by $0.13 to a mid-point of $0.55. This results in full-year adjusted EPS guidance of $0.47 to $0.62.”

Further, the Company announced updated full-year adjusted gross margin guidance of 25.25% - 26.25%, adjusted operating margin guidance of 3.0% - 3.75% and adjusted EBITDA margin guidance of 7.5% - 8.25% primarily related to incremental supply chain related costs and other externalities, including currency exchange rates. The Company maintained the guided effective tax rate of 22.5% - 27.5%.
