Otter Tail Corporation Announces Record Second Quarter Earnings, Maintains Electric Segment Guidance and Increases Consolidated 2024 Annual Earnings Guidance

FERGUS FALLS, Minnesota - Otter Tail Corporation (Nasdaq: OTTR) today announced financial results for the quarter ended June 30, 2024.

SUMMARY

•Diluted earnings per share increased 6% to $2.07 per share compared to the second quarter of 2023.

•Midpoint of 2024 earnings guidance increased 8% to $6.92 per share, or a return on equity of 18.7%.

•Received approval from the Minnesota Public Utilities Commission on Integrated Resource Plan.

CEO OVERVIEW

"We are pleased with our second quarter financial results," said President and CEO Chuck MacFarlane, "as our team members continue to perform well amid changing market conditions. Plastics segment earnings increased 9 percent compared to the second quarter of 2023 due to higher sales volumes driven by customer sales volume growth and improved end market demand, partially offset by lower sales prices. Manufacturing segment earnings increased 15 percent, primarily driven by higher margins at BTD Manufacturing, partially offset by lower sales volumes. Electric segment earnings decreased 6 percent from the same time last year due to the impact of unfavorable weather.

"In May, Otter Tail Power received approval from the Minnesota Public Utilities Commission on its Integrated Resource Plan. The decision authorizes the addition of 200 to 300 megawatts of solar generation by 2027, and 150 to 200 megawatts of wind generation and 20 to 75 megawatts of battery storage by 2029. Otter Tail Power also received approval to designate the Minnesota portion of Coyote Station as an emergency-only resource starting as early as 2026, retaining the reliability benefits from the facility while simultaneously reducing its output and emissions.

"The process to receive final approval of our Integrated Resource Plan was complicated by changing energy policy and environmental regulation impacting the power system and changing market conditions in MISO influencing our preferred plan since our initial filing in 2021. I am grateful to our team members and the other parties to the docket for reaching a favorable outcome that helps to preserve reliability while we continue transitioning to cleaner energy.

"Despite our strong quarterly financial results within the Manufacturing segment, we continue to face end market demand related headwinds and anticipate conditions to soften further in the second half of 2024. We will continue to take action to manage costs and mitigate the impact of lower sales volumes.

"Our Plastics segment continues to perform exceptionally well, capitalizing on customer sales volume growth and distributor and end market demand. The sales price of PVC pipe continues to decline but at a slower rate than what we originally anticipated.

"We are increasing our 2024 diluted earnings per share guidance to a range of $6.77 to $7.07 from our previous range of $6.23 to $6.53 primarily due to continued strength within the Plastics segment."

QUARTERLY DIVIDEND

On August 5, 2024, the corporation's Board of Directors declared a quarterly common stock dividend of $0.4675 per share. This dividend is payable September 10, 2024 to shareholders of record on August 15, 2024.

CASH FLOWS AND LIQUIDITY

Our consolidated cash provided by operating activities for the six months ended June 30, 2024 was $223.5 million compared to $184.5 million for the six months ended June 30, 2023, with the increase primarily due to increased earnings from our Plastics segment.

Investing activities for the six months ended June 30, 2024 included capital expenditures of $175.5 million and the purchase of long-term marketable securities of $50.1 million. Capital expenditures during the period were largely within our Electric segment, including investments in our wind repowering and advanced metering infrastructure projects, but also included continued investments in our manufacturing facility expansion projects in Arizona and Georgia. Financing activities for the six months ended June 30, 2024 included the issuance of $120.0 million of long-term debt at Otter Tail Power; the proceeds of which were used to repay short-term borrowings, fund capital investments, and support operating activities. Financing activities for the six months ended June 30, 2024 also included dividend payments of $39.1 million.

As of June 30, 2024, we had $170.0 million and $148.1 million of available liquidity under our Otter Tail Corporation and Otter Tail Power Credit Agreements, respectively, along with $230.7 million of available cash and cash equivalents, for total available liquidity of $548.7 million.

The following table summarizes the estimated effect on diluted earnings per share of the difference in retail kilowatt-hour (kwh) sales under actual weather conditions and expected retail kwh sales under normal weather conditions for the three months ended June 30, 2024 and 2023.

	2024 vs Normal	2024 vs 2023	2023 vs Normal
Effect on Diluted Earnings Per Share	$	(0.03)	$	(0.07)	$	0.04

Operating Revenues decreased $0.9 million primarily due to a decrease in retail revenue from the impact of unfavorable weather, as well as decreased transmission revenue. During the second quarter last year updates were made to estimated project costs for certain transmission projects and previously estimated recovery amounts for annual operating expenses were finalized which resulted in a nonrecurring increase in revenue during the period. The impact of unfavorable weather and decreases in transmission revenues were partially offset by an increase in retail revenues due to an interim rate increase in North Dakota in connection with our rate case filed in November 2023, increased fuel recovery revenues, and increased commercial and industrial sales.

Net Income decreased $1.1 million primarily due to the impact of unfavorable weather, as described above, partially offset by decreased operating and maintenance expenses, the interim rate increase in North Dakota, and increased commercial and industrial sales.

Manufacturing Segment

Three Months Ended June 30,
(in thousands)	2024	2023	$ Change	% Change
Operating Revenues	$	96,684	$	102,475	$	(5,791)	(5.7)	%
Net Income	6,835	5,969	866	14.5

Operating Revenues decreased $5.8 million primarily due to decreased sales volumes at both of our manufacturing businesses, with an overall sales volume decrease of 13% compared to the same period last year. At BTD Manufacturing, our contract metal fabricator, sales volumes declined primarily in the lawn and garden and agriculture end markets. A 31% decline in scrap metal revenues also contributed to the overall decrease in operating revenues. Decreased sales volumes and scrap revenues were partially offset by increased steel prices, resulting in a 5% increase in material costs, which are passed through to customers. At T.O. Plastics, our plastics thermoforming manufacturer, sales volume declines were primarily attributable to decreased sales of horticulture products as customers and distributors continued to reduce inventory levels from the high levels previously established due to supply chain challenges.

Net Income increased $0.9 million primarily due to increased margins at BTD Manufacturing driven by a positive impact from the timing of pass-through steel cost fluctuations and the selling of lower cost inventory, as well as favorable product mix compared to the same period last year. These positive impacts were partially offset by lower sales volumes and lower scrap sales, as described above. Decreased profit margins at T.O. Plastics driven by a reduced leverage of fixed manufacturing costs resulting from decreased production and sales volumes, as described above, also partially offset the overall increase in earnings compared to the same period last year.

Plastics Segment

Three Months Ended June 30,
(in thousands)	2024	2023	$ Change	% Change
Operating Revenues	$	132,824	$	121,478	$	11,346	9.3	%
Net Income	60,612	55,392	5,220	9.4

Operating Revenues increased $11.3 million primarily due to a 26% increase in sales volumes driven by customer sales volume growth and distributor and end market demand. Sales volumes in the second quarter of last year were negatively impacted by distributors' inventory management strategies amid uncertain market conditions. Although demand has recovered from last year, sales prices have continued to decline. Sales prices decreased 13% compared to the same period last year, partially offsetting the impact of increased sales volumes.

Net Income increased $5.2 million primarily due to increased sales volumes, as described above. Resin and other input material costs decreased 14% compared to the same period last year and have remained relatively stable during the first half of the year.

2024 BUSINESS OUTLOOK

We are increasing our 2024 diluted earnings per share range to $6.77 to $7.07. We expect our earnings mix in 2024, based on our updated guidance, to be approximately 31% from our Electric segment and 69% from our Manufacturing and Plastics segments, net of corporate costs.

The segment components of our 2024 diluted earnings per share guidance compared with actual earnings for 2023 are as follows:

2024 EPS Guidance	2024 EPS Guidance
2023 EPS by Segment	May 6, 2024	August 5, 2024
Low	High	Low	High
Electric	$	2.01	$	2.13	$	2.17	$	2.13	$	2.17
Manufacturing	0.51	0.45	0.49	0.36	0.40
Plastics	4.47	3.78	3.97	4.35	4.54
Corporate	0.01	(0.13)	(0.10)	(0.07)	(0.04)
Total	$	7.00	$	6.23	$	6.53	$	6.77	$	7.07
Return on Equity	22.1	%	17.1	%	17.8	%	18.3	%	19.0	%

The following items contribute to our revised 2024 earnings guidance:

Electric Segment - We are maintaining our guidance, expecting earnings to increase 7% over 2023.

Manufacturing Segment - We are decreasing our segment earnings guidance based on:

•Anticipated lower sales volumes as end market demand softens, primarily within the recreational vehicle, agriculture, construction and horticulture markets, and

•Declining operating margins as lower production and sales volumes negatively impact leverage of our fixed manufacturing costs.

Plastics Segment - We are increasing our segment earnings guidance based on:

•Better than expected financial results in the second quarter of 2024, and

•A slower decline in product sales prices than previously expected over the second half of 2024.

Corporate Costs - We are reducing our corporate cost estimate primarily due to an increase in expected income on our cash equivalent investments from a higher anticipated yield and an increase in invested funds driven by an increase in expected earnings and cash flows from our Plastics segment.
